A group of isotopes representing various stages of radioactive decay in which the heavier members of the group are transformed into successively lighter ones, the lightest being stable. In nuclear science, the decay chain refers to the radioactive decay of different discrete radioactive decay products as a chained series of transformations. Most radioactive elements do not decay directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is reached. Decay stages are referred to by their relationship to previous or subsequent stages. A parent isotope is one that undergoes decay to form a daughter isotope. The daughter isotope may be stable or it may decay to form a daughter isotope of its own. The daughter of a daughter isotope is sometimes called a granddaughter isotope. The time it takes for a single parent atom to decay to an atom of its daughter isotope can vary widely, not only for different parent- daughter chains, but also for identical pairings of parent and daughter isotopes. While the decay of a single atom occurs spontaneously, the decay of an initial population of identical atoms over time, t, follows a decaying exponential distribution, e-?t, where ? is called a decay constant. Because of this exponential nature, one of the properties of an isotope is its half-life, the time by which half of an initial number of identical parent radioisotopes have decayed to their daughters. Half-lives have been determined in laboratories for thousands of radioisotopes (or, radionuclides). These can range from nearly instantaneous to as much as 1019 years or more. The intermediate stages often emit more radioactivity than the original radioisotope. When equilibrium is achieved, a granddaughter isotope is present in proportion to its half-life; but since its activity is inversely proportional to its half-life, any nuclide in the decay chain finally contributes as much as the head of the chain. For example, natural uranium is not significantly radioactive, but pitchblende, a uranium ore, is 13 times more radioactive because of the radium and other daughter isotopes it contains. Not only are unstable radium isotopes significant radioactivity emitters, but as the next stage in the decay chain they also generate radon, a heavy, inert, naturally occurring radioactive gas. Rock containing thorium and/or uranium (such as some granites) emits radon gas that can accumulate in enclosed places such as basements or underground mines. Radon exposure is considered the leading cause of lung cancer in non- smokers.

It is also used as a coagulant in products like tofu.[3] In the natural state, unrefined calcium sulfate is a translucent, crystalline white rock. When sold as a color-indicating variant under the name Drierite, it appears blue or pink due to impregnation with Cobalt(II) chloride, which functions as a moisture indicator. The hemihydrate (CaSO4·~0.5H2O) is better known as plaster of Paris, while the dihydrate (CaSO4·2H2O) occurs naturally as gypsum. The anhydrous form occurs naturally as ß-anhydrite. Depending on the method of calcination of calcium sulfate dihydrate, specific hemihydrates are sometimes distinguished: alpha-hemihydrate and beta- hemihydrate.[4] They appear to differ only in crystal size. Alpha-hemihydrate crystals are more prismatic than beta-hemihydrate crystals and, when mixed with water, form a much stronger and harder superstructure.[5] Solution n should be 5 here Calcium sulfate (or calcium sulphate) is a common laboratory and industrial chemical.

The race industry and its elite enablers take it as self-evident that high black incarceration rates result from discrimination. At a presidential primary debate this Martin Luther King Day, for instance, Senator Barack Obama charged that blacks and whites “are arrested at very different rates, are convicted at very different rates, [and] receive very different sentences . . . for the same crime.” Not to be outdone, Senator Hillary Clinton promptly denounced the “disgrace of a criminal-justice system that incarcerates so many more African-Americans proportionately than whites.” Racial activists usually remain assiduously silent about that problem. But in 2005, the black homicide rate was over seven times higher than that of whites and Hispanics combined, according to the federal Bureau of Justice Statistics. From 1976 to 2005, blacks committed over 52 percent of all murders in America. In 2006, the black arrest rate for most crimes was two to nearly three times blacks’ representation in the population. Blacks constituted 39.3 percent of all violent-crime arrests, including 56.3 percent of all robbery and 34.5 percent of all aggravated- assault arrests, and 29.4 percent of all property-crime arrests. The advocates acknowledge such crime data only indirectly: by charging bias on the part of the system’s decision makers. As Obama suggested in the Martin Luther King debate, police, prosecutors, and judges treat blacks and whites differently “for the same crime.” The media love to target the federal crack penalties because crack defendants are likely to be black. In 2006, 81 percent of federal crack defendants were black, while only 27 percent of federal powder-cocaine defendants were. Since federal crack rules are more severe than those for powder, and crack offenders are disproportionately black, those rules must explain why so many blacks are in prison, the conventional wisdom holds. The press has covered this development voraciously, serving up a massive dose of crack revisionism aimed at proving the racist origins of the war on crack. Crack was never a big deal, the revisionist story line goes. But when Boston Celtics draft pick Len Bias died of a crack overdose in 1986, the media went into overdrive covering the crack phenomenon. “Images—or perhaps anecdotes—about the evils of crack, and the street crime it was presumed to stoke” circulated, as the New York Times archly put it in a December 2007 article. A “moral panic” (Michael Tonry’s term) ensued about an imaginary threat from a powerless minority group. Whites feared that addicted blacks would invade their neighborhoods. Sensational stories about “crack babies” surfaced. All this hysteria resulted in the unnecessary federal crack penalties. Those who tar the criminal-justice system as racist often make a broader claim: incarceration doesn’t even lower crime, making the nation’s skyrocketing prison rolls a particularly senseless injustice. Incarceration foes are right about one thing: the.

the resting membrane potential for most animal cells is negative, because the inside of thecell is more negatively charged than the outside of the cell----answer ===================================================================== ========== For the sensory system to capacity, neurons must have the capacity to send and get signals. These signs are conceivable in light of the fact that every neuron has a charged cell layer (a voltage contrast between within and the outside). The charge of this film can change because of neurotransmitter atoms discharged from different neurons and ecological boosts. Any voltage is a distinction in electric potential between two focuses; for instance, the detachment of positive and negative electric charges on inverse sides of a resistive boundary. To see how neurons impart, one should first comprehend the premise of charged films and the standard or \"resting\" layer charge. The lipid bilayer layer that encompasses a neuron is impermeable to charged atoms or particles. To enter or leave the neuron, particles must go through uncommon proteins called particle channels that traverse the film. Particle channels have diverse arrangements: open, shut, and idle . Some particle channels should be actuated with a specific end goal to open and permit particles to go into or out of the cell. These particle channels are touchy to the earth and can change their shape in like manner. Particle channels that change their structure because of voltage changes are called voltage-gated particle channels. Voltage-gated particle channels control the relative centralizations of various particles inside and outside the cell. The distinction in complete charge between within and outside of the phone is known as the layer potential. Particle channel arrangements Voltage-gated particle channels are shut at the resting potential and open in light of changes in film voltage. After enactment, they get to be inactivated for a brief period and will no longer open in light of a flag. Resting Membrane Potential For calm cells, the moderately static layer potential is known as the resting film potential. The resting layer potential is at harmony since it depends on the steady consumption of vitality for its upkeep. It is commanded by the ionic species in the framework that has the best conductance over the layer. For most cells, this is potassium. As potassium is additionally the particle with the most-negative harmony potential, as a rule the resting potential can be not any more negative than the potassium balance potential. A neuron very still is adversely charged on the grounds that within a cell is around 70 millivolts more negative than the outside (70 mV); this number shifts by neuron sort and by species. This voltage is known as the resting film potential and is created by contrasts in the convergences of particles inside and outside the cell. In the event that the film were similarly porous to all particles, every kind of particle woul.

Stiction or adhesion between the substrate (usually silicon based) and the microstructure occurs during the isotropic wet etching of the sacrificial layer. The capillary forces due to the surface tension of the liquid between the microstructure and substrate during drying of the wet etchant cause the two surfaces to adhere together. Separating the two surfaces is often complicated due to the fragile nature of the microstructure. Stiction is often circumvented by the use of a sublimating fluid (often supercritical CO2, which has extremely low surface tension) drying process where the liquid phase is bypassed. CO2 displaces the rinsing fluid and is heated past the supercritical point. As the chamber pressure is slowly released the CO2 sublimates thereby preventing stiction.
