Boolean algebra (XOR) structural algebraic, that is, to the logical operators and, or, negate and Yai exclusive deals. The name of this algebra, from the name of George Boole, English mathematician taken (1854) who tried to clash of algebraic predicate logic. Today Boolean algebra to the extent in the design of circuits, electronics goes to work. Claude Shannon, pioneer of the computer, figures the first time of this algebra in the design of computer interest....

The level of assurance in sterilization or the abbreviation SAL in microbiology to describe the probability of stay a unit(whether by the piece or material) after the process of sterilization, and sterilization. Manufacturers of medical equipment, design processes, sterilization to very low levels(one in a million) stay defined and standardized. In other words, in the definition of this coefficient, a is a hypothetical, so planning to be that as long as it should be from any one megabit undergo the process of sterilization is only a bit non-sterile stay.

attention to this point, it is essential that Microbiology is impossible to prove that all microorganisms is discovered, have been destroyed, because, firstly, may be undetectable cuddly only because this is the moment of Test in the appropriate environment, activities, understanding, and the Duma may include microorganisms is discovered, not discovered. so in these conditions, the coefficient of contingency SAL (or probability stay a bit) can be used....

In graph theory, etc. search, depth first (briefly DFS) is an algorithm scrolling graph that for scrolling or searching a tree or a graph goes to work.

search Strategy Depth-First, for scrolling the graph, as the name suggests, the \"search deeper in the graph, until possible\".

algorithm from the root starts (in the graph or tree without a root Vertex enviable as Root, choose to be) and in each step the neighbors of the vertices of the current through the ridge, the outgoing head of the current, respectively, and, as soon as the confrontation with the neighbor that had previously not seen. recursively, for which the helm as the head of the current runs. In the event that all the neighbors had previously been seen. the algorithm back round and makes the implementation of the algorithm for from which to helm the ongoing've reached, etc. continues. In other words, the algorithm as much as possible, to a depth of more and more and goes in the face of a deadlock rollback. This process, as long as all vertices, attainable from the root are seen continues.

Also in the issues that different states correspond to the vertices of a graph have, and problem solving requires finding the top of the goal with the peculiarities of the certain. search depth-first for acts. So that each time the algorithm to the first neighbor of a vertex in the Graph Search and in the result each time to a depth of more and more in the graph goes up to reach that all its neighbors have been seen that in the recent state of the ... algorithm to the first back that the neighbor is still not seen. This trend, to the point continues that the head goal is found, or probably all, the graph scrolling. Of course, the implementation of a clever algorithm with the choice of arrange the right to check the neighbors haven't seen the helm of the current to if the first algorithm to check the neighbor pay that for topical and selective guzzle to the helm of the goal closer. will be possible which usually in reducing the time to run effective.

from a practical point of view, for the implementation of the algorithm, a stack (stack) is used. So that each time the login to a head not seen, then the vertices in the Stack put and when back round the top of the stack, we remove. So during the whole algorithm, the first element of the stack top are check. Implementation details continue will come.

When in the graph, a portion of the search that makes it possible to save full them due to the memory limit does not exist, in the event that during the path traversal by an algorithm that from the roots start. very big. the algorithm the problem will be encountered. In fact, this is a simple solution that \" that up to now we've seen the save, We\" does not always work. As possible enough memory to do this, we don't have. Of course, this problem by limiting the depth of search in each time implementation of the algorithm can be solved that eventually the algorithm, the deepening of repetitive (Iterative Deepening) will last....

Poly that briefly PIB called. From the polymerization of ISO-bu toluene gotten that comes in masses different molecular applications of various production and consumption looks like. Rating this building saturation and passing the low water and . Grades, molecular mass, due to the softness of the atoms and neutral, and the acceptance of other grades as a filter at the base of The considered). Grades has a mass average molecular as liquid oily, clear, colorless, high viscosity, which set free, mineral oil are mixed, and additives to oil process. Grades, molecular mass, high usable developer, bitumen and fuel usages

the major applications of poly-ISO-butylene include: Z – Poly ISO butylene has a molecular mass in the production adhesive and base B - Poly ISO butylene has a molecular mass medium in the production of additives to engine oil C - Poly ISO butylene has a molecular mass, high in production efficiency, bitumen and fuel

Poly (PIB). Type polymers that: the thermoplastic of the polymeric material are that the molecules, they are of different sizes next to each other have been found and the bond between the chains of adjacent chemists of the type of Link is very weak, secondary ( ). In conclusion, the existence of these links, secondary poor mechanical properties of this type of polymers compactness is lower.Thermoplastic, because of the molecules different form. has a melting point certain are not. They are in the normal temperature environment, the Solid was cholera, this increase in temperature, soft and ductile. very high covalent bonds between the atoms in the linear chain had been destroyed, and the polymer burns or conversion to charcoal. When the polymer is exposed to oxygen, etc., ultraviolet, and about the invasion of the bacteria used, even at low temperatures, disappears. lower than the temperature of the environment behavioral crispy from your show.

the structure of the microscopic they usually are part crystalline and part amorphous or wholly amorphous. Frequently, to improve the mechanical properties, they have a small amount of material to add them. When tension acts to thermoplastic on the weak link between the chains of molecular overcome. chains relative to each other can spin it and slip. The ease of slipping them to the structure of the polymer, temperature and speed of deformation depends on. The application of poly-ISO-butylene: the use of poly (PIB) as a material substitute in the formulation (HIPS), PIB )), Poly ISO butylene, solvent, toluene was used as glue and in some places as oil, adhesive......

The photovoltaic or the abbreviation PV is one of the types of systems generating electricity from solar energy. In this method, the use of solar cells, solar panel produces direct electricity from the sun radiation becomes possible. Solar cells of the type of semiconductor that can , i.e., the second element is abundant the Earth's crust are made. When the light of the sun to a cell, photovoltaic sheds, etc. between the two negative electrode and a positive potential difference update, and this has caused a current flow between them.
