had been just recently discovered at the time 1895. It is energy released by the splitting (fission) or merging together (fusion) of the nuclei of atoms. The conversion of nuclear mass to energy is consistent with the mass-energy equivalence formula E = m.c², in which E = energy release, m = mass defect, and c = the speed of light in a vacuum. Nuclear chemistry can be used as a form of alchemy to turn lead into gold or change any atom to any other atom (albeit through many steps). Radionuclide (radioisotope) production often involves irradiation of another isotope (or more precisely a nuclide), with alpha particles, beta particles, or gamma rays. Iron has the highest binding energy per nucleon of any atom. If an atom of lower average binding energy is changed into an atom of higher average binding energy, energy is given off. What is nuclear fusion? Nuclear fusion is the process by which multiple like-

would be like without electricity. Yet like air and water, we tend to take electricity for granted. Everyday, we use electricity to do many jobs for us -- from lighting and heating/cooling our homes, to powering our televisions and computers. Electricity is a controllable and convenient form of energy used in the applications of heat, light and power. 7.1 The science of electricity In order to understand how electric charge moves from one atom to another, we need to know something about atoms. Everything in the universe is made of atoms--every star, every tree, every animal. The human body is made of atoms. Air and water are, too. Atoms are the building blocks of the universe. Atoms are so small that millions of them would fit on the head of a pin. Atoms are made of even smaller particles. The center of an atom is called the nucleus. It is made of particles called protons and neutrons. The protons and neutrons are very small, but

The 2 conditions given for hydrogen bonding are: 1) A hydrogen atom must be covalently bonded to O, N or F atom. I can understand this part, as O, N and F are highly electronegative and will leave the H with a positive dipole (more or less a H+ ion). 2) The other condition is that the atom with a lone pair which the H is hydrogen-bonded to must be O, N or F. 3.Kirjeldage erinevusi taime- ja loomarakkude vahel. 4.Kirjutage Henderson-Hasselbach´i võrrand.

The last supernova in our own galaxy exploded in 1604, rivaling Jupiter's brightness in the night sky and deeply impressing Johannes Kepler, the pioneering astronomer. A nearby supernova--within a few light-years--would bathe the Earth in lethal radiation. Yet the legacy of supernovas is as close as our own bodies. The carbon in our cells, the oxygen in the air, the silicon in rocks and computer chips, the iron in our blood and our machines--just about every atom heavier than hydrogen and helium--was forged inside ancient stars and strewn across the universe when they exploded billions of years ago. Eager to understand our origins and, in some cases, simply wild about things that go bang, astronomers have been struggling for decades to understand why stars that shine peacefully for millions of years suddenly blow up. Lately they've had two big breaks. One is a revelation about potent blasts of high-energy gamma
gains or loses an electron or electrons, when dissolved in a solvent like water. A classic example is table salt, chemical formula NaCl, which dissociates into a positively charge sodium ions and negatively charged chloride ions when dissolved in water. Water just so happens to be the most versatile solvent there is, a property it owes to the arrangement of its hydrogen and oxygen atoms. Without getting too into the details, every H2O molecule possesses a partial negative charge near its oxygen atom and partial positive charge near its hydrogen atoms. The polar nature of water's structure allows it to dissolve more substances than any liquid on Earth (which explains why it's known in chemistry circles as "the universal solvent"), including electrolytes like sodium, potassium, calcium, chloride, magnesium, and hydrogen phosphate. There are many other electrolytes, but these, in particular, are important for normal physiological function

as the co-inventor of the Geiger counter and for the Geiger-Marsden experiment which discovered the atomic nucleus. Geiger was born at Neustadt-an-der-Haardt, Germany. He was one of five children born to the Indologist Wilhelm Ludwig Geiger, who was professor at the University of Erlangen. Nagaoka Hantaro (August 15, 1865 December 11, 1950) was a Japanese physicist and a pioneer of Japanese physics in the early Meiji period. In 1904 he developed an early, incorrect "planetary model" of the atom (the Saturnian model).[1] The model was based around an analogy to the explanation of the stability of the Saturn rings (the rings are stable because the planet they orbit is very, very massive). So, the model made two predictions: * a very massive nucleus (in analogy to a very massive planet) * electrons revolving around the nucleus, bound by electrostatic forces (in analogy to the rings revolving around Saturn, bound by gravitational forces).

The toxicokinetics of formaldehyde after inhalation, oral, or dermal exposure has been reported in several species by many investigators. The toxicokinetics in all of the animals studied is similar across species lines. Formaldehyde is an essential metabolic intermediate in all cells. It is produced during the normal metabolism of serine, glycine, methionine, and choline and also by the demethylation of N-, S-, and O-methyl compounds. After oxidation of formaldehyde to formate, the carbon atom is further oxidized to carbon dioxide (CO2) or incorporated into purines, thymidine, and amino acids via tetrahydrofolatedependent one-carbon biosynthetic pathways. Exogenous formaldehyde appears to be readily absorbed from the respiratory and gastrointestinal tracts, but poorly absorbed following dermal application. Formaldehyde is metabolized to formate by the enzyme formaldehyde dehydrogenase; this appears to take place at the initial site of contact. Being

[2] [edit]5' Processing Main article: 5' cap [edit]Capping Capping of the pre-mRNA involves the addition of 7-methylguanosine (m7G) to the 5' end. To achieve this, the terminal 5' phosphate requires removal, which is done with the aid of aphosphatase enzyme. The enzyme guanosyl transferase then catalyses the reaction, which produces the diphosphate 5' end. The diphosphate 5' prime end then attacks the gamma phosphorus atom of a GTP molecule in order to add the guanine residue in a 5'5' triphosphate link. The enzyme (guanine- N7-)-methyltransferase ("cap MTase") transfers a methyl group from S-adenosyl methionine to the guanine ring.[3] This type of cap, with just the (m7G) in position is called a cap 0 structure. The ribose of the adjacent nucleotidemay also be methylated to give a cap 1. Methylation of nucleotides downstream of the RNA molecule produce cap 2, cap 3 structures and so on. In
SOOME Uurimistöö koostaja: Kertu Kristmann 10 klass. Õpetaja: Ene Lüüs Soome üldiseloomustus Soome Vabariik paikneb Põhja-Euroopas. Soome on üks Põhjamaadest, naabriteks on Rootsi ja Venemaa. Riik piirneb idast Venemaaga (1313 km piiri), põhjast Norraga (727 km piiri) ja läänest Rootsiga (586 km piiri). Kuigi soomlased on entiliselt võrdlemisi ühtne, jaguneb rahvas Soome viieks regiooniks: Pealinnaregioon, Lõuna-Soome regioon, LääneSoome regioon, Soome-Järveregioon ja Lapimaa. Riigikeelteks on Soome ja rootsi keel. Ärisuhtluses saab enamikul juhtudel kasutada inglise keelt. Soome pindala on 338 030 km² (305 470 km² maad, 31 560 km² siseveekogusid). Maast umbes 70% on kaetud metsaga, 10% on siseveekogude all ja 8% on haritavat maad. Riigi pindala kasvab umbes 7 km² aastas maapinna kerkimise tõttu. Soome Vabar...
[2] [edit]5' Processing Main article: 5' cap [edit]Capping Capping of the pre-mRNA involves the addition of 7-methylguanosine (m7G) to the 5' end. To achieve this, the terminal 5' phosphate requires removal, which is done with the aid of aphosphatase enzyme. The enzyme guanosyl transferase then catalyses the reaction, which produces the diphosphate 5' end. The diphosphate 5' prime end then attacks the gamma phosphorus atom of a GTP molecule in order to add the guanine residue in a 5'5' triphosphate link. The enzyme (guanine- N7-)-methyltransferase ("cap MTase") transfers a methyl group from S-adenosyl methionine to the guanine ring.[3] This type of cap, with just the (m7G) in position is called a cap 0 structure. The ribose of the adjacent nucleotidemay also be methylated to give a cap 1. Methylation of nucleotides downstream of the RNA molecule produce cap 2, cap 3 structures and so on. In
schemes and formal meters. Free verse is apparent throughout Whitman's works, which he patterned after ancient poetic forms, incantations, and praises from The Bible (Psalms) and Homer. He attempts to mirror the patterns of spoken language. Whitman's values are reflected in his subject matter and style. In "Song of Myself #1," for example, Whitman writes: I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you. (l.13) Whitman celebrates unity of all life and people. His belief in equality for all people is also depicted in these lines. The following line reflects Whitman's love of nature: My tongue, every atom of my blood, form'd from this soil, this air... (l.6) For Whitman to say he was formed from nature shows just how much he believed he was one with nature. The "I" has become identified with every element in the universe
1. STYLE The term "style" is polysemantic (has many meanings): a Latin word "stilus" originally meant a writing instrument used by ancient people. Already in classical Latin the meaning was extended to denote the manner of expressing one's ideas in written or oral form. Jonathan Swift defined style as "proper words in proper places". In present day English the word "style" is used in about a dozen of principle meanings: 1. the characteristic manner in which a writer expresses his/her ideas (e.g. style of Byron) 2. the manner of expressing ideas, characteristic of a literary movement or period 3. the use of language typical of a literary genre (e.g. the style of a comedy, drama, novel). 4. the selective use of language that depends on spheres / areas of human activity (e.g. style of fiction, scientific prose, newspapers, business correspondence, etc.). STYLISTICS Stylistics is the study of s...

It is the elusive “life” that no scientist has ever found because the consciousness that is looking for it is it. Physicists have discovered that the apparent solidity of matter is an illusion created by our senses. this includes the physical body, which we perceive and think of as form, but 99.99% of which is actually empty space. This is how vast the space is between the atoms compared to their size,and there is as much space again within each atom. The physical body is no more than a misperception of who you are. In many ways, it is a microcosmic version of outer space. To give you an idea of how vast the space ins between celestial bodies, consider this: light traveling at a constant speed of 186,000 miles (300,000 kilometers) per second takes just over one second to travel between the earth and the moon; light from the sun takes about eight minutes to reach the earth. Light from our nearest neighbor in space, a star

In this early 21st century, Africans don’t have the capacity to discover oil; we don’t have the capacity to transport the oil to the destination where it would be refined; we don’t have vessel to transport the oil back to us for consumption. At a time when Indians and the Pakistanis have both detonated the atom bomb, when China is providing the technology for quick acceleration of launching satellites into orbit, we Africans still don’t have the capacity even to refine the oil for ourselves. Kai! And we so happy there is oil in Ghana!) If you are talking of a state of Black economy, you have to talk about a people who are able to create products from its inception to market. You cannot talk of an economy where the people are mere consumers. Take a walk through the theatres of the marketplace

America, and soon a flood of material was being sent to Germany disguised as hundreds of periods in telegraph blanks, love letters, business communications, family missives, or sometimes as a strip of the tiny film hidden under a stamp. The very first discovered, and the most frightening, was one in which a spy was asked to discover "Where are being made tests with uranium?" at a time when the United States was fighting to keep secret its development of the atom bomb. The "Mexican microdot ring," which operated from a suburb of Mexico City, microphotographed trade and technical publications that were barred from international channels—a favorite was Iron Age, with statistics on American steel production—and sent them to cover addresses in Europe on a wholesale basis, with as many as twenty pats in a single letter. Technical drawings also went by microdot. Other microdots talked of
