...Shane T. Moore Sept.12, 2013 Experiment 1: SLIME (Starting Labs Is Mighty Exciting) Abstract In this experiment we investigate the properties of SLIME. Substitution of polyvinyl alcohol instead of Guar gum makes this experiment quite accessible. The Slime is prepared by mixing a solution of (Na2B4O7*10H2O) sodium tetraborate decahydrate (Borax) and H2O with a solution of polyvinyl alcohol (pva) and H2O. Then stirring for ~10 minutes to obtain the final product, SLIME. The product was examined and noted on the non-Newtonian fluid properties. Object The object of this lab is to become familiar with writing scientific reports. In doing so, SLIME is prepared along with examining the results and investigating the non-Newtonian fluid properties. Theory Working with organic and inorganic materials to successfully turn out a product, observe and note step-by-step, is a fundamental process for writing a scientific report. By mixing the sodium borate solution with the PVA solution, non-Newtonian fluid- like properties start to become apparent. When kneading the SLIME, the strands of pva are held together on a molecular level by joining them with bridges of boron dioxide from a borate molecule. Sodium tetraborate decahydrate is commonly used.1 Procedure The experimental procedure conducted is...

...Under Standing Basic Aqidah I. Aqidah (from root word aqd; plural aqaid) Means tying, confirming, consolidation, affirmation, holding together and making firm. II. Aqidah can be defined as a principle/belief in which there is no room for doubt on the part of the one who believes in it. Therefore that which a person believes in is his aqidah whether it is true or false. in an Islamic context it refers to belief (in the heart) rather than (visible) actions, such as believing in the existence of Allah and in the Messengers. The aqidah of Ahl as Sunnah walJamaah, is the true aqidah with which Allah is pleased with. This is the aqidah of the best 3 generations The sahabaah The Tabiin & those who followed them in truth. III. Aqidah in shariah terminology Refers to things which a person must believe to be true in his heart & of which he should be certain & with which he should be content So that they are believed with certain faith that is unshaken by doubts. It is faith not contaminated by any kinds of doubts In accordance with reality Unaffected by doubt or speculation If knowledge does not attain the degree of certain faith it cannot be called aqidah. It is called aqidah because a person ties or attaches (ya'qidu) his heart to it. IV. Islamic aqidah Islamic aqidah means: belief in the Lordship & Divinity of Allah in His Names & Attributes in His Angels His Messengers The Last Day The divine Decree both good & bad All...

...Analyzing the elements of music is very important in order to play the music with feeling and understanding. The first element is melody. In the first seven bars of the Hallelujah Chorus, the melody is in the soprano with the notes D A B A. From 4'33", There was not exactly a melody in this piece, but since everybody is silent, you could hear many sounds that you do not normally focus on. On the recording I listened to, I heard a melody of the audience coughing, sniffing, whispering, and shifting in their seats. The second element, harmony is heard in Hallelujah a lot. For example, half of the first measure of the music is a D major chord (tonic), and it is followed by a dominant chord, then resolving back to the tonic, which creates an effect of building up tension, then letting it go. In 4'33", there is harmony when two people either shuffle, giggle, or make noise at the same time. Maybe they will cough in harmony. Rhythm is very important in the Hallelujah. For example, on the fourth bar of the SATB chorus, there is a dotted quarter note, then three eighth notes, followed by rest to create suspense. The rhythm of 4'33" is slightly harder to determine. There is not exactly any written rhythm, but the definition of rhythm is "The lengths of sounds and silences and their arrangements." I guess, then the rhythm must be four minutes thirty three seconds of rest. They next element is dynamics. For example, "Hallelujah" in the first few bars are very...

...protect the environment, the researchers decided to produce briquettes from algae and waste papers. An unnaturally high abundance of algae blocks sunlight from reaching underwater organisms, interferes with living creatures that filter water to gain food, and sometimes actually consumes oxygen, resulting in fish deaths. Some species of algae even produce toxins which may be poisonous to marine life. On the other hand, papers thrown and are not useful anymore also called waste papers can be beneficial to the environment and humankind. The combined algae and waste papers which have little significance to people can be used to make alternative briquettes that will reduce the usage of coals and will be able to protect the environment and help the peoples cooking needs. STATEMENT OF THE PROBLEM The researchers aim to produce an alternative briquette out of waste papers and algae dust. Specifically, the researchers seek to answer the following questions: 1. Is/Are there significant difference/s between the alternative briquette and the commercially available charcoal in terms of : a) Odor b) Smoke produced c) Cooking and Boiling Time 2. What is the size and shape of the briquette needed to produce efficient alternative for charcoal? 3. How does the amount of alternative briquette affect the length of cooking and boiling time? HYPOTHESES 1) There is/are...

...Dark Matter: A Basic Understanding Introduction Many people, from the inquisitive, to those involved in the astronomical sciences have questioned the existence of Dark Matter. While it is called many things today, I will continue to refer to this unseen substance by its original name, Dark Matter. As it is still a theory being researched today to validate its existence and make-up, the discovery of dark matter was first presented to the world some time ago by two very intelligent astronomers. In coming to understand this matter, some of the most common questions we find ourselves asking are: What is it? And, How was it discovered? The most difficult question we all seem to face is Does it really exist? While quite tricky, this question is one that each of us have to conclude an answer to on our own. Therefore to start, I will address the more common questions first, and then I will provide my own answer to the question of its existence. Dark Matter: What is it? When first being introduced to Dark Matter, the first question we find ourselves asking is what is it? In and out of the scientific community dark matter is commonly referred to as the source of extra gravity, or the mysterious form of matter that is unseen. A more refined scientific definition for dark matter is a nonluminous, undetectable, invisible material in the universe that makes up about 70%-80% of its mass. In short, dark matter is an unseen form of material...

...are variations of reasons to why this situation occurs to a number of citizens in this globe; furthermore, these reasons also offer the information on what causes the increases and decreases within the unemployment-associated statistics presented on many articles and texts. One of the key reasons which signify the cause of being unemployed is lack of intelligence taken from past educational experience; this occurs through all educational timings. Many unemployed workers who tend to never obtain a job or a suitable career are due to their failed grades which seem unappealing and unqualified for the jobs requirements (Possibly, a certain-convinced length of knowledge and understanding is looked-for). Within a certain extent, for one employee to apply for a job, one requires to have a high understanding basic knowledge; for one of the leading countries, Great Britain, employees are required to achieve at least a C in GCSE Mathematics, Science, and certainly, English when taking these GCSE courses. For the period of high school in the United Kingdom, students are expected to fulfill the two GCSE years. The results from the exams then will be finalized and will be required when submitting the application for ones future career. Secondly, appalling common attitudes and behaviors which requires in ones individual personality could cause the situation of being jobless. Having an inhospitable individualism could affect the employees... on the usage of coal and is known as War on Coal. The environmental protection agency has funded many ads which support the President Obamas vision of limiting carbon dioxide emissions from coal fired power plants. The ad campaign will target five states New Hampshire, Illinois, Pennsylvania, Arizona and Washington D.C. According to environmental protection agency the congress has to decide if they are in favor of applying limits on highest carbon emitting sources or they prefer not to impose limits. The coal industry is urging President Obamas administration to ease carbon dioxide limits for coal plants. The coal industry also state the fact that they have invested a huge amount on pollution control and if the environmental protection agency forces t to close the coal fired power plant they will lose a large revenue. Also President Obama announced that we will use his executive authority to address global warming and his plan involves limiting the carbon dioxide emissions from power plants. The environmental protection agency previously proposed emissions limits that would effectively ban the construction of coal-fired power plants unless they used carbon capture technology, which is not commercially viable. According to the American coalition for clean coal electricity, more than 280 coal fired power plants will shut down due...

Use these types of binders to produce coal briquettes, the briquetting process can be free of drying system, producing water-proof briquettes, not afraid of rain, can be stacked out of the coal briquette factory, suitable for long-distance transportation, etc.

Coal dust can be blended with certain additives to form a coal briquette with catalytic, activating and sulfur-fixing functions, which accelerates the reaction speed of coal briquette in the combustion process, improves combustion conditions, and efficiently and rationally utilizes heat energy, greatly lower the harmful exhaust emissions.

The coal briquetting process is simple with a small investment. Coal dust is also lower in price. The coal dust only follows a two steps process of mixing and briquetting to obtain the finished coal briquette.

Civil coal briquette is mainly divided into honeycomb coal briquette and coal ball briquette according to the appearance and shape of coal. These briquettes are usually used for BBQ, heating, cooking, fireplace, etc.

Lime carbonized coal briquette uses coal briquette to decompose CO2 at high temperatures in a gasifier and use that as a raw material for carbonic acid producing. Its void ratio is 10 times higher than that of raw coal, so it has high chemical activity, and the binder source is wide and with low price.

However, due to the poor adhesion of lime, the thermal and thermal strength of coal briquette is not enough. It can only be applied to some of the furnaces. The amount of lime added is as high as 20% ~ 30%, and the coal briquette has low fixed carbon content.

This kind of coal briquette needs suitable anthracite for production, can be directly used in the furnace, the temperature is equivalent to anthracite. The disadvantage is that it is not waterproof, and can only be briquetted beside the furnace. The briquette application is subject to greater restrictions.

Industrial steam coal briquette is mainly used as fuel for industrial boilers, industrial furnaces, locomotives, etc. The coal briquette is produced by adding a certain amount of biomass to the fuel which is also called as a bio-coal briquette.

The bio-coal briquette is briquetting the 70% to 85% coal by weight and 15% to 30% biomass on a high pressure. Biomass can be referred to crop straw and biomass industrial waste such as firewood, rice husks, bark, wood chips, bagasse, etc.

Develop high-sulfur rate industrial coal briquette on coal gasification. Develop industrial coal briquette that can use coal slime and biomass to improve resource utilization. Developing cheaper industrial coal briquette based on local conditions, and higher quality, more energy-efficient coal briquettes are the way forward.
