how humans evolved to be natural omnivores

how humans evolved to be natural omnivores

Chemically, we lack cellulases or cellulosic symbionts that many herbivores have, and have lots of proteases that carnivores do. But we do have sucrases that let us digest fruits. Humans require vitamin B12 to thrive, which can only come from animal sources or certain bacteria (vegans must supplement their diet). We also require vitamin C, which is present in citrus fruits and organ meat, the latter probably being our evolutionary ancestor's main source.

Interestingly, we have very powerful livers (the detoxification organ) and a very strong ability to smell rot/decay/decomposition relative to other animals. This suggests we may have evolved as scavengers, eating dead (but not too decayed) carcasses killed by other animals.

Lastly, our closest evolutionary relatives, the chimpanzees, are omnivores. The leading theory as to how humans evolved is that we became long-distance runners and hunted food by running it down until it tired, and that our access to meat and protein enabled our brains to evolve further than otherwise. So meat-eating is in our history as well as our DNA and physiology.

Vegetarians need not despair: now that we've evolved beyond having to hunt, we don't need to eat meat to survive or thrive at all. A vegan diet is possible and healthy for humans (with care to get enough vitamin B12 and a diverse set of amino acids). A meat-only diet is also possible and even healthy (with care to get a diverse set of vitamins and minerals by eating organs, not just muscle and fat). Omnivores can pick and choose their foods, as opposed to, say, carnivorous cats, that would die on a vegan diet. Still, if someone tries to push a vegan diet on you by saying that we were originally herbivores, that's simply not true.

"Attached" TNG, Episode 7x08 Production number: 40277-260 First aired: 8 November 1993 159th of 176 produced in TNG 159th of 176 released in TNG 293rd of 801 released in all Written by Nicholas Sagan Directed by Jonathan Frakes In-universe date 47304.2 (2370) After escaping imprisonment on an alien world, Picard and Dr. Crusher find that their thoughts are connected by brain implants.

Dr. Crusher and Captain Picard are sharing breakfast in the captain's quarters. While Crusher tells Picard of the burgeoning romance between Nurse Alyssa Ogawa and Ensign Markson, Picard seems preoccupied. When confronted with his inattention, Picard confesses that he is, while not exactly worried, bothered by the idea of admitting only half of Kesprytt III to the Federation while leaving the other half out. Crusher attempts to alleviate his concerns by pointing out that the Kes inhabit about three-quarters of the planet and present all the characteristics necessary for admission, even if the Prytt are xenophobic and wish only to be left alone. If Australia had refused to join the United Earth Government in 2150, Crusher hypothetically asks Picard, should the people of Earth have been left out of the Federation? Picard is arguing that the cases are hardly analogous when he is interrupted by a communication from Commander Riker, alerting him to the fact that Ambassador Mauric is awaiting them on the planet. Picard and Crusher leave for the transporter room, but not before Crusher promises a special Vulcan dish for the next morning's breakfast.

Lieutenant Worf is standing ready at the transporter console and beams Picard and Crusher to Mauric's chambers, after receiving confirmation from Kes Security Relay Station One that they have dropped their defense shield and are ready to receive transport. Worf is about to leave the transporter room after successfully beaming down the two officers when he receives word from Security Relay Station 1 that Picard and Crusher never arrived. He is stunned.

Picard regains consciousness lying on a dirty stone floor in a dimly-lit room. Crusher is slumped against a wall nearby. He calls her by her name, and she wakes at his touch. Together they observe their surroundings, and find that the last thing either remembers is beginning to transport off the Enterprise. Picard deduces that they must be on Kesprytt, in a prison cell of some kind, although he can think of no reason for Ambassador Mauric to detain them. When he stands up to look at the barred window, Crusher notices a device of some sort protruding from the back of his neck. Upon closer examination, she finds an implant, connected directly to the brain stem; an identical implant also juts from her own neck. Picard asks if it could be a coercive device, and Crusher observes dryly that she doubts it's intended for their health.

The door slides open. Three guards enter, two armed with phasers and one carrying a tricorder. While they are being scanned with the tricorder, Picard demands to know what it is going on, but receives no answer. When Crusher asks why they are being held hostage, the guard with the tricorder responds that they are not hostages, but prisoners held by the authority of the Prytt Security Ministry, charged with conspiring with the enemy. She accuses the Federation of attempting to establish a military alliance with the Kes, and informs them that such an attempt will not be tolerated. When Picard tries to tell her that the Federation is not interested in destroying the Prytt, the guard will not listen, informing them that the truth will soon be known from their implants, which are being calibrated to their psi wave pattern. Picard tells her that the data from the implants will conclusively prove they are telling the truth and the guard says they will see about that. The guards leave.

Meanwhile, on the Enterprise, Data has run a diagnostic of the targeting components of the transporter and has determined that there has been no malfunction. Worf, however, has been looking at the sensor logs and has found an unusual concentration of antigravitons in the emitter coil. Data realizes that this suggests a tractor beam, which might have deflected the transporter beam to another set of coordinates. He is unable to determine the exact coordinates, but tells Riker that the beam originated somewhere in the Prytt Alliance. Worf wonders aloud what the Prytt Alliance could have wanted with Picard and Crusher, and Riker responds that it's going to be hard to find out the Prytt are xenophobic, and have consistently shied away from any outside contact at all. He decides to work through the Kes, and orders Worf to contact Ambassador Mauric and schedule a meeting immediately.

Picard is systematically trying the tiny bars on the window when he senses Crusher staring at him. She protests that she is only trying to think of a way to escape. He continues to search for a structural flaw, telling Crusher that the important thing to remember in any confinement situation is to think positively. Picard reminds her that there is a solution to every puzzle and a way out of every box they just have to find it. The door slides open, disclosing a male guard with a phaser and a covered plate. He sets the plate down just inside the door, keeping the phaser on them at all times, and leaves. Picard rushes the door as it closes, but is too late to keep it open. He swears, but Crusher observes that at least they won't starve. Upon lifting the cover, however, Crusher finds not food, but her medical tricorder. It is not only fully functional, but has been modified to include a map with an escape route. Picard gloomily observes that this may be part of a carefully-laid trap, but Crusher tells him that she would rather take her chances "out there," and he agrees. The code to the door has been programmed into the tricorder, and they creep out without further discussion.

Having arrived on the Enterprise, Ambassador Mauric presents his formal apologies to Riker in the observation lounge on behalf of his government for the unfortunate incident involving the Enterprise's officers. Riker and Counselor Deanna Troi assure Mauric that the Federation does not blame the Kes for what happened, and that the Enterprise's primary concern is rescuing Picard and Crusher. Mauric offers his government's assistance, and assures them that the Kes are prepared to send a hostage rescue team into the Prytt capital city in three hours. Riker rolls his eyes, looks at Troi, and tells Mauric that they have not even attempted a diplomatic solution yet, and that he would rather not use excessive force until they have exhausted all other options. Options, however, are something Mauric sees little of: the Kes have no formal diplomatic relationship with the Prytt, no ambassadors, and no way of communication. Troi asks about the system in place for a planetary emergency, but Mauric says they have never had need of such a system.

Finally, when Worf suggests that they can determine the Prytt communication frequencies and simply establish a link themselves, Mauric replies that he must be blunt the Prytt are a xenophobic, fanatical people who refuse to engage in civilized discourse, and it has been nearly a century since there has been any diplomatic contact between the Kes and the Prytt. In response to Troi's suggestion that the Prytt might have changed over the century, Mauric is adamant that they've indeed changed very little. Riker is annoyed by the Kes ambassador, and tells him that with all due respect, the Enterprise must communicate with the Prytt before he will sanction the use of force. Although Mauric assents, his placating manner is subverted by his statement that he will continue making preparations for a hostage rescue mission. Riker agrees, and brings the meeting to a close by getting up, along with Worf and Troi. Mauric has one last request, however due to the presumed breach of the Kes communication network, he would like to establish a base of communications on the Enterprise. Riker assigns Worf to help him.

Worf leads Mauric and his young assistant to standard guest quarters. Mauric sends Worf into the room first to make sure there are no traps, then waits until his assistant carefully scans the entire suite before pronouncing it acceptable. Worf is offended by his excessive caution, and stiffly offers his assistance as Security Chief of the Enterprise. Mauric says they will manage alone, effectively dismissing Worf.

Meanwhile, Crusher and Picard escape from the Prytt base into subterranean caves, about thirty meters above a lava flow. They follow the escape map on the tricorder through a cave of erupting gas spouts, barely managing to flee the area before an enormous fire explosion of gas pursues them.

Back on the Enterprise, Lieutenant Commander Data has scanned the entire Prytt communication network and found the primary access module to their central government. On orders from Riker, Data hails the Prime Minister's office. The official who answers is initially unaware of the origin of the communication. Riker gets no further than identifying himself and his ship before the official interrupts in fear and anger and, upon learning that the ship has no authorization from the Prytt Security Ministry, abruptly terminates the connection.

Within seconds, the Enterprise is hailed by the Prytt Security Council, represented by Security Minister Lorin, who was the tricorder-bearing guard from Picard and Crusher's cell. Lorin demands the immediate cessation of all communication with her people. Riker counters by asking to discuss Picard and Crusher's confinement, but Lorin says there is nothing to discuss. As Mauric and his aide appear on the bridge, she continues by threatening aggressive action against the Enterprise unless it ceases all communication with the Prytt, and then abruptly ends the connection. Worf assures Riker that the Prytt pose no appreciable military threat to the Enterprise. Riker nonetheless orders the shields to be kept up for the time being.

Mauric then tells Riker that while the Enterprise's efforts to effect a diplomatic solution have stalled, a Kes operative has freed Picard and Crusher from Prytt custody and set them on their way to the border between Kes and Prytt. Riker asks how exactly the two officers are meant to cross the fortified border, and Mauric says the information is confidential. When Riker presses the matter, Mauric intimates that the bridge is not sufficiently secure for him to explain. Neither is the captain's ready room, Riker's next suggestion. Only the quarters assigned to Mauric and his aide are acceptable to the Kes ambassador, who claims that they are "safer". Riker is nonplussed, but agrees.

On the planet, Picard and Crusher are navigating through a maze of underground tunnels. Crusher announces that she is also thirsty, under the impression that Picard had just made the same observation aloud. He protests that he only thought about his thirst, and did not express it in audible speech. They realize that the transceivers must have calibrated to their psi wave pattern, as threatened by Loren back in the cell, and are now transmitting their thoughts to one another. Their attempts to prove the hypothesis are unsuccessful, and they wonder if it might have been a fluke. In any case, however, the immediate concern of finding a way out demands their attention.

The map sends them to a great hill of rock, indicating that a ledge about thirty meters up leads to a tunnel that connects to the surface. Picard has just started to climb when he stops and turns, having felt a sudden sense of fear from Crusher. Crusher admits her fear of heights, and Picard attempts to calm her by telling her to pretend that she is on the holodeck. They begin to climb toward the ledge.

Entering Mauric's quarters, promptly scanned by the aide, Riker notices the "redecorating" done by the Kes. Machines and gadgets of all kinds now fill the room, humming and whirring away. Mauric characterizes them as a few pieces of equipment necessary for security, as the aide pronounces Riker "all right" to enter. Riker and Mauric huddle over a desk to discuss the situation. Demanding complete confidentiality, Mauric tells Riker that the Kes employ operatives in Prytt territory. The escape map provided to Picard and Crusher will lead them to a tavern in a village near the border, where these operatives will be waiting to help them cross. Riker is skeptical of the advisability of sending Human Starfleet officers into a Prytt village, but Mauric downplays the risk in a manner that is faintly patronizing, citing the great deal of experience the Kes have with the Prytt. He attempts to reassure the skeptical Riker by pointing out that the Kes have no reason to wish Picard and Crusher harm, as they still hope that the Enterprise will support the Kes petition to enter the Federation. Riker smiles wanly.

Picard and Crusher emerge from underground into a sunny, deserted countryside. They hike down a hill amidst tall green grass as Picard observes that one of the two is hungry. Crusher admits it, and Picard pleads for her to think of something else, as he is becoming hungry himself just observing her thoughts of a large bowl of vegetable soup. Crusher remembers how her grandmother used to make it, with peas and carrots, but is interrupted by an exasperated Picard. She apologizes, but apparently indulges in the thought that he is being unreasonable. He abruptly stops and defends himself. They discuss the matter, and come to the decision that they cannot react to every thought that crosses the other's mind, and that there is a difference between thoughts and speech. Telepaths acquire new respect from the pair, as their experience demonstrates just how much clutter and flotsam the mind churns out on a continual basis.

When Picard thinks a joke to see if Crusher is "still listening," she realizes that the link is growing stronger. Picard suggests putting some distance between them to see if that helps, although he sarcastically observes, "not that I'm growing tired of hearing your most intimate thoughts." As soon as they are only a couple of yards apart, however, they are overcome with pain and nausea. Crusher's tricorder tells them there's nothing physically wrong with them, but a second try yields the same result, this time with only a step's distance. They continue their journey side by side.

As their link grows stronger, Picard "remembers" Dr. Crusher's memory as if it were his own. He finishes a sentence about a boy, Tom Norris, that Crusher had a crush on when she was younger. Crusher acknowledges Picard's sudden knowledge of shame on the doctor's part, and Crusher admits she acted unkindly towards Norris by asking him whether he was growing in a beard or if it was just dirt on his face. Crusher thought at the time that she was merely being cute but she ended up hurting his feelings. At that moment, they see who they think is a Prytt operative, but was probably a Kes operative.

Meanwhile on the Enterprise, Riker and Mauric argue about how safe Picard and Crusher are and whether or not they will know to meet up with their operatives. Mauric makes the accusation that since Picard and Crusher did not meet with their operative at the border, that they must be meeting the Prytt in secret in order to negotiate a military alliance. Riker says it's ridiculous, and denies it. Mauric doesn't believe him and wants to leave the ship. Riker agrees, and tells him to take his "junk" with him.

Picard and Crusher try to find something to eat before nightfall, but there is nothing edible on the planet's surface. Gathered around a fire, Picard tells Crusher that they will probably be on the Enterprise by tomorrow and that she can plant herself in front of a replicator with a fork and knife. Crusher and Picard talk about breakfast and the Vulcan dish she was meant to have prepared. Picard, it turns out, just wants a simple meal in the morning, not the elaborate things they have been eating. Crusher realizes that he wants coffee and croissants, and by her own admission, says she also likes the simple things. They then both agree that coffee and croissants are what they shall be having for breakfast in the future. When she mentions when she took a trip with her son Wesley when he was very young to Balfour Lake, she begins to reference her deceased husband, Jack Crusher, and then she senses Picard's feeling towards her. Picard, a bit embarrassed, at first denies it, but Crusher realizes that Picard has had romantic feelings towards her even when she was married. Picard admits that because he was afraid of what would happen, he tried denying her application to be aboard the Enterprise; he also says that he had those feelings from when Crusher was married and then hated himself for wanting to act on his romantic feelings when Jack died. He never did act on them and he says that eventually, those feelings went away. Crusher acknowledges that and then says they are now good friends, seven years later. Feeling both a little awkward from this experience, Crusher announces that they have a lot of ground to cover tomorrow and probably should get some sleep. Picard and Crusher both lay down near the fire and fall asleep.

Riker tries to contact the Prytt again, but they will not listen. Fed up by the two nations' lack of communication, Riker has Worf transport the Prytt security minister, Lorin, directly to the observation lounge against her will, to force a dialogue with Mauric. However, the "dialogue" is entirely unproductive, as the two ministers hurl various conspiracy theories at each other for instance, Lorin says the Prytt "know" about the Kes's plans to build new orbital attack satellites with Federation technology, and warns Mauric that they have already prepared defenses; Mauric calls these accusations ridiculous, but rejoins that the Kes "know" about the Prytt's plans to use Federation aid to regain control of certain territory; Lorin says the Prytt don't need aid, the territory is quite clearly theirs and so on.

Riker slams a hand down on the observation lounge's table and tells both ministers he is finished with them. He allays Lorin's concerns by assuring her that the Kes's application for Federation membership will be denied. Mauric, outraged, says Riker has no authority to make such a decision, and threatens to go over his head to the Federation Council. Riker rejoins that his report to the Council will carry serious weight, and his report will state in no uncertain terms that the Kes, while outwardly democratic and friendly, are also paranoid and suspicious to the point of insanity. The Federation does not ask much from its members, but it does assume that they are at least willing to trust each other, and the Kes have a long way to go before they can meet this basic requirement. Moreover, although the Federation was initially willing to consider admitting KesPrytt because the Kes are the majority faction, Lorin and Mauric's "dialogue" has graphically illustrated that the division between the Kes and the Prytt is a much deeper problem than the Kes were willing to admit, and disqualifies their world for membership.

Addressing Lorin, Riker demands the return of Picard and Crusher, but she stubbornly insists that they are still suspected of espionage. Riker turns up the heat on Lorin, telling her that if anything happens to their missing officers, then Starfleet will subject her country to increasing scrutiny, ranging anywhere from more starships in orbit to sensor sweeps to maybe even away teams conducting interrogations of hundreds of Prytt citizens a very unsettling prospect to Lorin, as Riker makes clear that she will be held responsible by her own people for the Federation intrusion.

On the planet's surface, Picard and Crusher are attacked by the Prytt. They run for a while before getting to the border. Crusher disables the force field just long enough for Picard to get through but she is captured by the Prytt. However, Riker has finally made Lorin understand, and she tells her operatives on the surface to give the Enterprise the coordinates of both Picard and Crusher. The Captain and Doctor both arrive in the transporter room and they continue to share some thoughts, literally, while Riker walks behind them utterly confused as to why they are laughing.

Later that night, Picard and Crusher have just finished an elegant dinner, and both have already had their implants removed. Picard and Crusher are both relieved that they won't be hearing each other's thoughts any longer. Crusher then says "a penny for your thoughts" to Picard and reveals that while she was trying to sleep on Kesprytt, Picard fell asleep faster than her and that he had some very interesting dreams. Picard asks her not to blame him for his dreams because it wasn't something he had control over, as he was sleeping. Crusher then asks what about the things he does have control over, such as his thoughts when he was awake. Picard says that now that they both know how they feel, maybe they shouldn't be afraid to explore the possibilities that are in store for them. Crusher replies "Or maybe we should be afraid.", she then kisses Picard on the cheek. Crusher suggests maybe she should be going now. Picard agrees and they kiss on the lips. She departs from the room and stands outside the door reflecting for a moment on what happened. Picard goes to the dinner table and blows out the candles and looks out the window into space.

"And when Jack died, you felt guilty." "I felt guilty before he died. Having feelings like that for my best friend's wife... and then later after the accident, I promised myself that I would never tell you how I felt. It would be like betraying my friend." "That's why you didn't want me on the Enterprise seven years ago."

"We still plan to take our petition directly to the Federation Council! They'll listen-!" "They will also listen to the reports of the Captain of the Enterprise and his First Officer! And I can tell you right now the First Officer's report will go something like this: 'Kesprytt, a deeply troubled world with social, political, and military problems that they have yet to resolve. The Kes, while a friendly and democratic people, are driven by suspicion, deviousness, and paranoia. It is the opinion of this officer that they are not ready for membership.'"

mobile crushers - metso outotec

mobile crushers - metso outotec

Mobile crushers are often referred to as mobile crushing plants. They are track-mounted crushing machines which, thanks to their mobility, can maximise productivity and reduce operating costs while increasing safety and reducing environmental impact.

The concept of mobile and semi-mobile crushers has been around for a long time, but for years many machines were very heavy and moving them required thoughtful planning. As result, the crushers that were supposed to be mobile were seldom relocated and tended stay put in permanent facilities.

Nowadays, the weight of mobile crushers has decreased considerably, and crushing as well as mobility properties improved notably. Mobility is not substitute for effective crushing anymore, and tracked mobile crushers meet the same basic criteria as stationary plants.

Mobile cone crushers are traditionally used as secondary, tertiary, and quaternary crushers. However, if the grain size of the processed material is small enough by nature, then they can also operate at the first stage of the crushing process.

Mobile HSI crushers have a horizontal impact crushing unit and they are used as primary, secondary, or tertiary crushers. Mobile VSI crushers, in turn, are equipped with vertical shaft impact crushing unit, and they are extremely efficient in the last stage of the crushing process, producing precisely shaped cubical end products.

Metso Outotecs mobile crushing equipment consists of two different product families, Lokotrack mobile crushers and Nordtrack mobile crushers. Both families can be utilized in aggregates production in quarries and construction sites, recycling applications, as well as in mining operations.

Nordtrack, on the other hand, is ideal if you work in short-term contracting jobs or are just starting your own operations. The family consists of two mobile jaw crusher models and one mobile impact crusher.

She descended upon Fdlan several thousand years in the past and took on a human form to live among the people. Her blood was used to create a race of beings called the Nabateans, also known as the Children of the Goddess. Her descendants would help pave a future for Fdlan of great technological and societal advancement. Her blessings were soon abused by the people of Fdlan, more specifically the people of a civilization named Agartha, leading to countless, pointless wars and even attempted to kill Sothis herself, seeing themselves as gods. The war resulted in massive bloodshed and Sothis exhausting her power to restore the land, taking place over centuries. One of her final children, Rhea, was born just as she finished restoring Fdlan. Needing to recover, she rested in the Holy Tomb, while the remaining Agarthans went underground.

A secret underground civilization composed of the remnants of Agartha, known as Those Who Slither in the Dark, used Sothis's vulnerability to their advantage. They convinced a lowly bandit, Nemesis, to raid the Holy Tomb and steal Sothis's remains. Using her blood, they planted her Crest of Flames into Nemesis, while also fashioning her bones using their technology to create the Sword of the Creator, a sword of unparalleled power when used in tandem with the Crest of Flames. Nemesis subsequently slaughtered many of the remaining Nabateans at Zanado using the sword, and Those Who Slither in the Dark used their blood and bones to create Crests and Heroes' Relics for at least eleven of Nemesis's allies. Rhea, the only survivor of the massacre, enraged and grief-stricken by the slaughter of her people and the theft of her mother, took on the name of Seiros and waged war against the King of Liberation to avenge her family and reclaim Sothis's remains. In the process, she founded the Adrestian Empire and the Church of Seiros, the latter devoted to the worship of Sothis.

Rhea was able to kill Nemesis and reclaim both Sothis's Crest Stone and the Sword of the Creator from him. Still in despair from the death of her mother, Rhea desired to revive her mother to recover what she had lost. Rhea's first attempt to revive Sothis using the Chalice of Beginnings and the blood of the Four Apostles resulted in the creation of an Umbral Beast, with the Apostles going into isolation shortly after. Rhea's later attempts involved creating a human vessel implanted with Sothis's Crest Stone in the hopes that Sothis could use them as a means to revive herself within them. Her first and subsequent attempts never manifested Sothis's consciousness, leading to several centuries passing, each time failing to produce a proper host for her mother's soul.

By the Imperial Year 1159, her twelfth vessel, Sitri, was yet again another failure, but things were different this time. Sitri fell in love with the Knights of Seiros captain, Jeralt and the two were married and expecting a child. Jeralt bore the Crest of Seiros due to Rhea transfusing her blood into him when he took a mortal blow meant for her. The union of Sitri and Jeralt resulted in a child, Byleth, who was born without a heartbeat. Sitri, near death from childbirth, pleaded with Rhea to place the Crest Stone into her child and she obliged. The transplant revived the child, and Sitri died shortly after. The extraordinary circumstances behind Byleth's conception lead to them being the perfect vessel for Sothis. However, before Rhea could take advantage of this miracle, Jeralt, having grown suspicious of Rhea as result of the death of his wife and Byleth's mysterious behavior and lack of a heartbeat, took advantage of a fire at the monastery to fake Byleth's death and disappear. Rhea was deeply distressed by Byleth's apparent death, and it would be 20 years before she would see Jeralt and Byleth again. Being a compatible vessel for Sothis, Byleth would occasionally see her in their dreams while growing up.

Shortly after this dream, Bylethalongside their father Jeraltare asked by three young students to help them repel some bandits. While most are dispatched, the leader, Kostas, manages to ambush Edelgard, and Byleth leaps between the two. Just as Kostas's axe is about to strike Byleth, time suddenly stops as Sothis uses her power to freeze time. She berates Byleth for their recklessness but is suddenly shocked by the fact that she is now able to remember her name. Pondering Byleth's fate, the two realize that Sothis can not only pause time, but also rewind it, granting Byleth a second chance to redo their rescue, this time disarming Kostas. Sothis continues with Byleth, speaking directly to them telepathically, unseen by the rest of the world. She also grants them the usage of her time manipulation power which she calls Divine Pulse.

In the aftermath of Jeralt's death, Byleth seeks revenge against his murderer Kronya. Though they are able to severely wound her, Solon appears and sacrifices her to send Byleth into a void. Unable to escape, Sothis bestows her full power onto Byleth by merging with them, fusing their souls. With her power, Byleth is able to escape, and while the two are forever bonded, she no longer appears before them.

Rhea, having seen Byleth with her mother's power, requests that they sit on Sothis's throne in the Holy Tomb in hopes that Sothis' mind would also merge with Byleth's. However, to her surprise, nothing happens as Sothis' mind had, in Rhea's words, already "vanished" from Byleth. They are still connected in a way, as seen in other scenes.

Sothis can be Byleth's lifelong partner should they choose her prior to the final battle of all four routes. Sothis's consciousness returns to confess her feelings to Byleth. She states that when she granted her full power to them, her soul had permanently bonded with them. When Byleth points out she said she could no longer speak to them, Sothis only replies that she also said they would always be together, and that she decided to come back to them in this way because Byleth was lonely. Even in the Crimson Flower route where Byleth loses the Crest of Flames, Sothis states that she no longer requires it as she is bound directly to their soul. Though still unseen by the rest of the world, Sothis happily declares her love for Byleth and plans to spend the rest of eternity with them.

Despite her youthful appearance, Sothis speaks and acts as though she were a grandmother. She is frustrated at her inability to recall her past. She is usually sleepy, especially in the earlier chapters of the story and sometimes dozes off or fades during conversations.

In the times she is awake, she offers commentary and questions the state of things, providing advice to Byleth on how to proceed. However, despite being a passenger within Byleth, she sees herself as above them, and sharply admonishes them when they respond to her with comments she deems foolish. She demands a certain level of respect despite the fact that she is ultimately powerless on her own as she must use Byleth as a means to interact with the outside world, albeit in a limited manner.

A feature available only in New Game+, Byleth can acquire the Sothis Shield. A unique battle command, they can use it once per battle. When used, Byleth will call upon Sothis, who will grant the player's entire force a temporary +7 buff to Resistance. The effect lasts three turns, decreasing in power each turn.

Sothis is a Dark Mythic Hero who is an Infantry Red Dragon unit as well. She is a potent offensive unit who can be terrifying to face and immensely useful on the other hand. Unfortunately, because she is a Dark Mythic Hero, she is not suited for offensive Aether Raids as using her incurs a score penalty. Nonetheless, for defensive Aether Raid teams or general Arena Teams, Sothis sits at the top as a powerful asset with no particular weakness in any of her stats other than middling defensive stats, but her weapon and skills solve this. Her Spd is among the best in the game, especially with an Asset, allowing her to easily prevent follow-up attacks and execute them herself against key match-ups as well as a respectable base 34 Atk for solid offense all around.

Sublime Surge negates "effective against dragon" weapon effect, thus neutralizing common anti-dragon threats like Marth, Lucina, Alm, and Legendary Tiki, covering what would have been her one glaring weakness. It also packs Distant Counter for good measure, allowing her to retaliate against strong ranged options while also exploiting their lower defensive stat. Her unique special Sirius boosts he damage by 30% based on her Spd stat and also recovers 30% of the damage she dealt, giving her solid damage and recovery when it activates.

Sothis's base kit focused mainly on offense with Atk/Spd Solo to boost her two key stats when isolated from her allies, Wrath to quickly charge her special when injured, and her new Time's Pulse grants a special cooldown -1 effect if her special was charged at the beginning of the turn.

Sothis is a tricky unit as her weapon immediately removes her weakness to anti-dragon weapon units. Blue close range units who can either bypass her speed tier and/or survive her magic based attacks are the best options. Fallen Hardin or Selkie are two excellent choices given that the former can double her regardless with Vengeful Fighter equipped and has decent bulk while the latter has the natural Res to resist her attack while her Spd neutralizes both of their abilities to follow-up, thus leaving it a matter of color advantage on Selkie's part. Guard and Special Fighter are the best skills to slow down her offense as she does rely on Sirius to cause as much damage as possible. Legendary Marth does not have dragon effectiveness as normal, but he has Binding Shield, neutralizing her ability to attack or perform follow-up attacks depending on who initiates battle. She is susceptible to Resistance based Ploys as well as Panic Ploy since she has average HP. Dazzling Staff/Wrathful Staff can also help to chip her down or if they attack an enemy within two spaces of her, using the two staffs with Savage Blow to chip away 14 of her health per attack.

Winter Sothis is more or less like her Mythic form, but in most ways, even more terrifying. She is a Green armored dragon with perhaps one of the strongest statline distributions with an incredible 51 Neutral Atk and 44 Spd with her weapon. Her Res is excellent as is her HP and while her Def is mediocre at best, it is still workable overall. She has only one noticeable weakness, but other than the main one listed bellow, she is an excellent armored fighter and can run a mixed bulk set with ease that allows her to perform in either turn without much difficulty.

Snow's Grace automatically neutralizes her Dragon status, allowing her to fully exploit her breath's adaptive damage against ranged units without suffering from dragon slaying weapons. For good measure, she gains +3 Spd to bring her to the aforementioned 44 neutral Spd. Finally, the weapon is at its strongest so long as she is over 50% health as she gains a +5 boost to her four core stats during combat as long as she fulfills this requirement. She also retains her unique special Sirius which boost her Atk by 30% of her Spd (thus a base 15 true damage with her neutral Spd and weapon in effect) and also heals her for 30% of the damage she dealt. This serves as an excellent damage boost and heal in one package, making it further difficult to engage her safely without restoring her back to health.

Distant Counter allows her to counterattack ranged enemies, cementing her ability to effectively check or threaten just about any unit in game. Special Fighter accelerates her special cooldown while slowing her enemies so long as her HP is 50% or more. Finally Threaten Attack Resistance inflicts Atk/Res -5 on enemies within two spaces while also boosting her Atk/Res by 5 if there is an enemy within two spaces of herself.

Her only notable weakness is her Armor status, which leaves her vulnerable to Armor slaying weapon users like Tobin or Hana who also have color advantage and can exploit her lower Def. While Legendary Marth does not deal effective damage, the Binding Shield prevents her from attacking. Firesweep Weapons can attack her in similar fashion without fearing retaliation. Finally Dazzling Staff/Wrathful Staff combo users can also achieve this same effect. Bear in mind that her bulk overall mitigates these to an extent where only a few instances occur where these are true counters.

Sothis appears in Super Smash Bros. Ultimate during Byleth's reveal trailer. The scenario is a spoof of Where the Goddess Dwells where Solon captures male Byleth in the void. Instead of giving him her powers, she uses an invitation for Smash to escape the void. Later, after Byleth is shown being defeated by the numerous swordsmen in Smash, in which Sothis asks how he plans on dealing with them despite being a swordsman himself. The scene immediately cuts to female Byleth instead, revealing that she is also playable in Ultimate. For her cheek, Sothis bequeaths Aymr, Areadbhar, and Failnaught for them to use in their moveset. Sothis cheers on Byleth as they enter Smash, vowing to lend her power.

In game, Sothis appears in Byleth's Final Smash, Progenitor God Ruptured Heaven during the start up sequence if the initial hit connects and grant Byleth her power saying "Your will and mine are now as one!", which transforms their hair color similar to how it is when the two merge. As the Final Smash concludes and the opponents are launched, Sothis is later heard saying "The end approaches!"

Byleth's sixth alternate costume directly references to Sothis, while Byleth's form when merged with Sothis is referenced in Byleth's seventh and eighth alternate costume. Sothis also appears as a Legendary Spirit as part of the Three Houses DLC spirits added to the game.

Its main features are that it is movable and walking freely, thus, the transition is more convenient to ensure safe operation. The station's output ranges from 10 to 650 tons per hour, and one production line can simultaneously produce four sizes of stones, sand and powder.

The mobile crusher can carry jaw crushers, impact crushers, cone crushers, vibrating screens, conveyors, etc. The complete ore processing line has significant quality, performance and price advantages, and is widely used in highway, railway, national defense and construction.

The crawler-type: crawler-type drive has the advantages of lowering the chassis of the whole machine, strong driving stability. The whole machine can work at complex sites with strong adaptability, especially good for climbing work.

It can also quickly enter the work site for immediate operation. The whole machine adopts steel structure which is sturdy and durable. Modular assembly makes various devices work together without affecting each other.

It can be divided into jaw crusher type, cone crusher type, hammer crusher type, impact crusher type, etc., due to the different types of crushers it carries, its function and adaptability are also different.

The jaw crusher is suitable for coarse crushing, the cone crusher and impact crusher are suitable for fine crushing, the hammer crusher can be used for one-time shaping, and the impact sand maker is used for sand making. In short, the user needs to combine his own needs when configuring the machines.

The two-machine mode usually consists of a mobile jaw crusher + a mobile cone crusher or a mobile jaw crusher + a mobile impact crusher. The two stations form a production line covering the processes of coarse crushing, fine crushing, screening, feeding and transportation;

When configuring a mobile crushing station, there have differences between the large output and small output. Generally, the line is 40-50 t/h. The small output can be matched into one mobile station and the large one generally requires two or more. Next, lets take a look at the specific configuration of the mobile crusher.

As far as the situation on the market is concerned, there are two main types of suppliers of mobile crushers. One is to have their own factories and sell the mobile crushing station by themselves. These suppliers are called direct sales manufacturers. And the other one is that there have no factories of its own, which means that they need to purchase the mobile crushing plant from others, and then sell the machines by themselves. This kind of supplier is called a sales-oriented manufacturer.

For these two manufacturers, the mobile crusher and other equipment processed by the former are closer to the factory price. The latter, because of the price difference in the middle, will be more expensive than the direct-selling manufacturer.

From the above, it can be seen that the direct-selling manufacturers are more favorable in price. Also, for direct-sales manufacturers, the problems of after-sales and accessory support of mobile crushers can be better guaranteed.

Henan HXJQ Machinery is a direct selling manufacturer, specializing in the production of various types of mining equipment for 40 years, with advanced technology and rich experience.

choosing a mobile impact crusher for recycling what you need to know

choosing a mobile impact crusher for recycling what you need to know

RPN connected with product experts and Canadian distributors representing eight of the leading global manufacturers of mobile impact crushers to gain a little more insight into the benefits, features and evolution of this integral tool of today's C&D, concrete and asphalt recycling industries.

Mobile impact crushers, also known as the tracked impact crusher or recycling impactor, are recognizable mainly due to the fact that these crushers are mounted on a tracked undercarriage. Overall range of capacity for mobile impact crushers is roughly about 100 to 500 tons per hour.

Today's mobile impact crushers are especially ideal for smaller-scale recycling operations, for on-site recycling of demolition waste, and for tight-space urban and roadside applications. These units feature a diesel or electric drive system, are transportable by trailer, and can be simply driven off at the location of material that needs to be processed, and go to work very quickly.

With their capability to produce accurately-sized end-product with a cubical end product shape, mobile impact crushers work well as closed circuit stand-alone plants, or they can add significant productivity to any operation, working in tandem with a jaw crusher or screen plant.

Tracked impact crushing plants have evolved greatly over the last several decades, as their designs have been continuously updated and as the crushing market has changed. Major trends include the introduction of electric drive and hybrid systems as opposed to diesel-hydraulic drive systems, and decreases in size, weight, fuel consumption, cost-per-ton, and sound and dust generation.

Today's mobile impact crushers are ideal for use in a wide range of applications, including as a mobile recovered concrete crusher, or for asphalt and mixed C&D waste. They are available compliant to Tier 4 Final emissions standards, and can be equipped with or without a built-in screen, as well as many options specifically geared towards creating recycled materials. Todays mobile impact crushers are safer, more mobile, easier to maintain and operate, and are available with sophisticated machine automation and monitoring.

"The growth in recycling of concrete and asphalt recycling industries has led to higher demand for smaller, more mobile crushers," says John O'Neill, McCloskey International's VP of sales. "Over the last 10 years we have improved our control panel systems to provide operators with more knowledge and information about what is going on inside their machines at all times. The units are also easier and faster to set up."

According to Daryl Todd of B.C.-based Frontline Machinery, the Canadian dealer for Belgium-based crushing and screening plant manufacturer Keestrack, "Wesee a strong movement towards turning concrete and asphalt rubble materials into higher quality recycled materials such as construction sand, washed recycled drain rock, road mulch, RAP (reclaimed asphalt pavement) and a host of other quality products with a much higher value.

"The impact crusher's ability to handle steel-reinforced concrete, along with custom options, such as plastics and wood-waste removal systems, washing systems and more, has enabled recyclers to create much higher quality end products, and crush and process materials previously deemed only waste, or too difficult to process."

"The reason is the quality of the material and very cubical shape produced. The impact crusher is a first- and second-stage crusher in one unit, so you can crush a 600-mm product down to a final product for resale as recycling aggregate.

"Our machines are excellent in recycling asphalt, as we can slow down the rotor speed to crush the asphalt, but not the aggregate inside the asphalt, so the material can be reused in asphalt mixing plants, a huge savings on cost."

According to Norbert Dieplinger, Austria-based SBM Mineral Processing's international business development manager, "Specs are getting tighter so crushers must be much more accurate than in the past. For example, a few years back you could just crush aggregate down to 0- to 3-inch material and use it for road base. Now, engineers are allowing the use of more and more recycled asphalt into their mix, instead of all-natural aggregate and crushed concrete, and not just as road base material. With impact crushers, the shape is exactly what you need, you can get down to smaller sizes and they can process building debris with rebar."

Alexander Taubinger, Rubble Master's managing director and VP sales, says "Cost of ownership and costs per ton are key figures for our customer base." Rubble Master machines feature a diesel-electric drive that burns less fuel, and low maintenance costs are due to the company's latest design and product development.

"Back in the day, it was all about tons per hour. Machines were built overly strong and heavy with large, inefficient power solutions. This is second or third priority these days, since contractors have to meet other job requirements when it comes to most recycling applications."

He adds that with respect to end markets, Rubble Master has always been focused on the final product size and quality. "Lots of contractors still only think about reducing the size of material. It's all about reusable and resalable product size and quality these days."

The changing value of recovered metal, especially over the last decade, is a consideration for all recyclers and contractors managing recycled materials. For users of mobile impact crushers in the processing of concrete and C&D rubble, even with the fluctuating price of recovered steel seen over the last several years, efficient metal separation remains a key component.

"Unfortunately, with the way things have turned as of late, scrap iron is not worth a lot. But I can tell you that having systems in place to remove it is paramount," says Tim Harms, crushing and screening product manager, Kolberg Pioneer (a KPI-JCI & ASTEC Screens company.)

"If you have any metal contamination in your end product, you'll be in trouble trying to resell that product. So it's very important to get it removed. Ten years ago, scrap was of higher value and that was part of the equation. Now it's just the fact that you need to get it out so that you can resell the product. Impact crushers are very good at liberating scrap iron from concrete."

Stephen Whyte, product manager, mobile product development, KPI-JCI & Astec Mobile Screens, adds that the growth of the contractor/rental market has also been key in driving the growth of all tracked crushing and screening plants.

"Guys today can load a tracked impact crusher, go do a job for a week, load it off on the weekend, and they can be set, ready to go on the next site the following week," says Whyte. "It's the contractor/rental market that's really driven the mobile impact crusher market."

He adds that for impact crushing in general, mobile, tracked units are the least path of resistance to get into the business. "You've got the highest reduction ratio. You've probably got the lowest capital investment. And you can get the most bang for your buck'. Almost always you will see entry-level tracked impactors as the first choice for contractors getting into the C&D materials recycling business, no matter the brand."

The stand-out feature of the mobile crusher or tracked impactor for recycling applications, is its mobility, combined with high productivity per hour. Units are fully self-contained on their tracked undercarriage and can easily be driven off a trailer by one operator and quickly put to work, with excellent capability for moving directly to materials. Some models are even capable of tracking (moving about on their tracks) while crushing.

"The ability to move within the job site and job to job is important to the contractor, or other end user, thus driving the demand for portable crushers," says Jody Beasley, national sales director at Screen Machine. "One of the biggest expenses in material processing is physically handling the material. Every time material is moved, labour and expenses are involved. Tracked impact crushers bring the machine to the job site, right to the pile, and allow for very efficient material processing.

"It's all about tons per hour. Our machines have been designed to produce maximum tonnage and one significant way they do that more efficiently is through our patented Crusher Relief System. The Screen Machine Crusher Relief System allows the operator to raise the crusher lid up to six inches while the machine is in operation. This is a huge help in preventing jams inside the crusher and ultimately delivers thousands of additional tons of product over the life of the machine."

According to Stephen Whyte, KPI-JCI and Astec Mobile Screens, "Mobile impact crushers are higher capacity than they were when they first came on. When the first tracked machines came in, they were seen as crushers that were highly portable but would do less weight than the typical portable [trailer-mounted] machine. Whereas now, some of the tracked machines we manufacture can reach those same capacities, and compete with the portable setups.

"Another great feature with our impact crushers is that they allow operators to crush and track at the same time," he continues. "This is why you'll see a lot of these units being used along the highway. One operator can basically load the machine and operate the tracked crusher at the same time."

"This is very important," adds Kolberg-Pioneer's Tim Harms. "You can be crushing and don't have to disengage the crusher to track the machine. You can continue to crush while the machine is being moved around on its tracks, which is a big advantage with respect to time savings. Time is of a huge value. If you lose 10 percent of your time, just because you've got to wait for the crusher to stop so you can move it, those are dollars."

Traditionally, mobile impact crushers have used a diesel-hydraulic engine for the track-drive and power to the crusher. The advent of electric-drive and hybrid systems is one of the main advancements that has occurred over the last decade, and its development is seen by many as one of the most significant trends going forward, especially considering the importance of fuel efficiency, rising transport and operational costs and the global focus on reducing emissions.

"Lowest cost per ton produced is crucial in the customer's business," says Metso Minerals' product manager, Jouni Hulttinen, who adds that main focus areas in their Lokotrack line development have been ease of transport, maintenance and service, as well as safety and energy efficiency.

"Energy efficiency has been a very focused development area," says Hulttinen. "We have reduced fuel consumption up to 20 percent with our tracked impactors." He says one good example is the Lokotrack LT1213(S) (S' designates a built-in screen component) which uses a stand-by function' where the machine switches to idling mode if there is no load on the engine. "Just five minutes on stand-by, per hour, can save 10 litres of fuel per day."

According to Norbert Dieplinger, the drive systems in crushers manufactured by SBM are available as diesel-electric or can be run 100-percent electric. "Not only does electric power reduce the carbon footprint, it can save contractors up to 30 percent on fuel costs when you compare them to the diesel-hydraulic drive systems that were common in the past and are still used by lots of manufacturers," he says.

"This permits high fuel efficiency and allows optimal loading of the crusher," explains Joe Schappert, Kleemann's senior technical sales manager. "Outstanding performance is made possible in part by the extremely efficient direct drive, with which these machines are equipped. A latest-generation diesel engine transmits its power almost loss-free directly to the flywheel of the crusher, via a robust fluid coupling and V-belts. This drive concept enables enormous versatility, as the rotor speed can be adjusted in four stages to suit different processing applications."

A first question to ask when considering a purchase, according to McCloskey's John O'Neill, is: what do you want the machine to do? He says it is necessary for a solid sense of reality to be a big part of the buying decision. "Too many times the customer is upset because they expect peak performance to be the norm, when they need to be looking at all aspects of their operation and how it can support the crusher and the desired end goals or products."

"What kind of support equipment is available and can it support the tonnage capacity of the crusher?" he asks. He adds that other important questions include: Who are the customers? What is the application you intend to use it for? What spec are you working with? How large are the piles to be crushed?"

"If the impact crusher needs a part or maintenance items, can you be confident that the manufacturer will get those parts to you as quickly as possible?" asks Screen Machine's Jody Beasley. "Our machines are manufactured in Ohio, and all parts orders are fulfilled here. We pride ourselves on the fact that more than 97 percent of in-stock parts orders ship the same day."

"All impactors are not created equal, and the differences are significant," says Daryl Todd, Frontline Machinery. "We strongly suggest taking a close look when comparing various models. Start off with the technical specifications, including engine horsepower, the weight of rotor and blow bars, as well as ease of transport, machine weight and dimensions."

Todd says there are many questions to ask, including: Is the rotor direct-drive from the engine, electric drive or hydraulic drive? What is the hopper capacity and feeding height? And what are the after-screen options - single-, double- or triple-deck? Does the machine have the ability to track while in full production? What type / quality are the key components such as hydraulics and electronics? And what is the type and quality of steel used in the frame, crusher housing and rotor? He adds that any mobile impact crusher should also have a user-friendly design, with ease of changing blow bars, and ease of access for maintenance and servicing.

Keestrack's Michael Brookshaw says one of the main questions to ask when considering an impact crusher is: can you transport the unit with your own transport means? "The material that you need to crush in your area is important," he says.

"Look at the costs per ton involved on the purchasing and running of the unit. What are the amounts of material that need to be crushed? Are they large deposits of 30,000 tons or smaller deposits of 500 to 1,000 tons? You should also consider the feed size and capacity that you will need. Would electric drive provide an advantage on the environmental side of the business?"

He adds that the technical aspects of the unit are also very important. Electric drive, pre-screen before the crusher, crusher overload system, pan feeder under the crusher, weight, as well as service and operator friendliness of the unit are all areas that need to be considered. Joe Schappert from Kleemann says that buyers considering a purchase should make sure they choose the correct size for the application and consider how product will flow through the crusher.

"The Kleemann Continuous Feed System (CFS) manages a more equal loading of the crushing area, in which the conveying frequencies of the feeder trough and the pre-screen are adapted independently of each other to the level of the crusher, thus significantly boosting performance.

"Our new impact crushers are differentiated by their size and productivity," continues Schappert. "Our model MR 110 Zsi EVO 2 has a crusher inlet opening of 43.3 inches (1,100 mm), and the MR 130 Zi EVO 2 has a crusher inlet opening of 51 inches (1,300 mm). These provide feed capacities of up to 350 or 450 tph, respectively.

"Consider diesel-electric drives," he adds. "Our latest EVO 2 Mobirex mobile impact crushers utilize direct-drive crushers and electric drives for the vibrating conveyors, belts and the pre-screen. This permits high fuel efficiency and allows optimal loading of the crusher."

Looking ahead, Daryl Todd of Frontline Machinery says there will be more hybrid technology, electric/diesel hybrids, meaning reduced fuel consumption, as well as improved noise reduction. He says that we'll also see advances in contaminant removal systems and washing systems integrated into closed-circuit impact crushers.

GPS systems are another area where Todd expects advances to continue. "GPS systems provide remote monitoring and control, tying in with onboard belt scales," he says. "This allows managers to have total insight into remote operations."

Michael Brookshaw of Keestrack says their telematic system allows customers, distributors and the manufacturer to monitor their machines, inform from distance and advise on capacity, running of the unit and fault finding.

"There has also been much development in the area of wear parts, which are more durable than ever," says Brookshaw. "Our electric-hybrid and full-hybrid system, which we call Keebrid, are excellent in the areas of durability, lower emissions, running costs and all environmental issues."

For McCloskey's John O'Neill, the trend of using one machine to do multiple parts of an operation will continue to decline. "The crusher should crush and the screeners should screen," he says. "Trying to squeeze it all onto one platform is hard and often results in compromises, which if not acceptable to the customer, can be disastrous on the job site."

Rubble Master's Taubinger expects to see improvements in efficiency in all regards. "We expect a very heavy focus on emissions such as dust and noise, as well as more fuel efficiency, safety and ease of operation."

"Advanced diagnostic tools can enable the operator to monitor processes in real time with the ability to adjust settings on a touch screen on the crusher, or even from inside an excavator cab. This leads to further increases in safety and efficiency with a reduction in maintenance, operating costs and downtime.

"Diesel-electric power is the future because of all the advantages it provides with respect to decreased fuel costs and decreased carbon footprint," adds Dieplinger, who also points out that this will make a big difference in years to come, especially considering new carbon taxes being implemented globally.

According to Metso's Jouni Hulttinen, base construction for bikeways, road base and industrial areas are growing end markets for material made from recycled C&D, concrete and asphalt. He says mobile impact crushers, and all types of crushers for recyclable materials, will increasingly move more towards application in the production of high-quality end products.

"Use of the end material has gone from the most basic application to higher-spec building materials," says Hulttinen. "The future trend will go more towards substituting aggregates, new concrete made from recycled concrete, and recycled asphalt added to make new asphalt." RPN
