Detergent properties of disinfectants are to remove liquid and solid contaminants from the surface and transferring them into the washing liquid in the form of solutions. Detergent action is manifested in the complex processes of interaction dirt, detergent and surfaces. The main phenomena determining the detergency, are the processes of physical and chemical adsorption, wetting, emulsification, foaming and stabilization. Methods for cleaning up surface based on the use of liquid detergent, include the processes of physical and chemical adsorption. Adsorption processes reduce the strength of contaminants on metallic surfaces in boundary layers, reduce the resistance to mechanical effects of pollution, contribute to an increase in dispersion and formation of microcracks on the surface of the material, which ultimately accelerates the removal of contaminants. By contacting solids and liquid detergent disinfectant on solid surfaces have a boundary layer, molecules which are not balanced with a liquid medium.
Therefore, the boundary layer has an excess free energy or adsorption activity. In general, the entire cleaning process can be structured in consecutive phases. Since almost all the pollution are hydrophobic, the water having a high surface tension, does not wet contaminated surfaces and contracts to individual drops. When dissolved in water, detergent disinfectant surface tension decreases, and the solution wets the pollution getting into its cracks and pores. It reduces the adhesion of the particle pollution among themselves and with the surface. Under the mechanical action, carried away by the molecules of detergent disinfectant mud particles into solution. Detergent molecules funds are adsorbed on the dirt and washed surfaces, which prevents the coarsening of the particles and their settling on the surface. As a result of pollution particles, in suspension are stabilized in the solution and removed with him. The quality of the cleaning solution adopted to judge by the number of formed foam. The foam helps keep the dispersed pollution and prevent its deposition on a clean surface. But to identify foaming cleanser with the action is not entirely correct, since it is not a specific characteristic of detergent action.
Drawing Technician in the Architecture. Bertran Stacke SUMMARY The present study it has for objective the elaboration of an article, being this, on Drawing Technician in the Architecture. A little on the work of the architect and its paper as professional using the drawing technician. 1. INTRODUCTION The objective of the article is to show the importance that the Drawing Technician has in companies and its projects. After theoretical study, a study of field with a company was made who uses the drawing technician. On the basis of all these information, the article were elaborated. 2.
THEORETICAL REFERENCIAL 2.1. DRAWING TECHNICIAN The drawing technician is a specialized branch of the drawing, characterized for its normalization and the appropriation that makes of the language of descriptive geometry. Such form of drawing is used as base for the projetual activity in you discipline as the architecture, design and engineering. In its more general context, the Drawing Technician engloba a set of necessary methodologies and procedures for the development and communication between projects, concepts and ideas and, in its more restricted context, mention the specifications to it techniques of products and systems. 2.1.1. DESCRIPTIVE GEOMETRY Descriptive Geometry (also called mongeana geometry or method of monge) is a branch of the geometry that has as objective to represent objects of three dimensions in a bidimensional plan.
This method was developed by Gaspard Monge and had great impact in the technological development since its systematization. 2.1.2. ARCHITECTURE The art or the technique is mentioned to it to project and to build the environment inhabited for the human being. In this direction, the architecture destacadamente deals with the organization of the space and its elements: in last instance, the architecture would deal with any problem of agency, organization, aesthetic and order of components in any situation of space arrangement.
Yogurt takes control of fermented milk and it adds to active bacteria cheers to him. She is one of healthful foods known for being a good source calcium and proteins, as well as other nutrients like the probiotic ones. All these are necessary to maintain our health and well-being. According to the most recent clinical studies in humans, a new type of yogurt exists that fights the Helicobacter plori, the bacterium that causes to the gastritis and the stomach ulcers. This new yogurt is original of Japan, and is praised by its unique approach to fight the ulcers. In the United States, approximately 25 million people have ulcers.
This yogurt is now available in Japan, Taiwan, and Korea. One announces that soon it will arrive at the United States. How the majority of the stomach ulcers Works Bacteri H. Plori are caused by bacterium H. plori, as well as by the excessive use of aspirins and NSAIDs (nonesteroideas anti-inflammatory drugs, by its abbreviations in English). Although the ulcers are commonly easy of to deal with the use about antibiotics and suppresors acids, many developing countries simply do not have access to options of treatment for the ulcers caused by bacterium H. plori. It is a new study, the investigators discovered that bacterium H plori seemed to depend on a called protein ureasa so that the bacterium adheres and infects to the cells in the cover of the stomach.
With base in this discovery, the investigators created a vaccine, injected chickens with ureasa, they hoped that the immunological system of the chickens created the antibodies for ureasa, and later collected the antibody of eggs. Next, the scientists gave him to eat to 42 people who had given positive for bacterium H. plori two cups or of yogurt simple or of yogurt with the antibody of ureasa by 4 weeks. After 4 weeks, that consumed yogurt fortified with the antibody of ureasa, they showed that its infection by bacterium H. plori had been finished. The acids of the stomach destroyed to antibody, but was not but until the antibody had worked fighting the bacterium. Even though yogurt is less effective to reduce to the levels of bacterium H. plori in comparison with antibiotics, still it is much more easy to take, since yogurt can be consumed every day and can become partly of the dietetic routine of the people.
This boarding searched to understand of what it consists the structure of the mind and as the cognitivas capacities are organized leaving of the estimated one of that the information process operates in ' ' mdulos' ' of form, relatively independent ones of the others, only processing a type of information of each time, possessing one form of innate and not apprehended functioning. According to Fodor, what it occurs in the truth, it is that throughout our lives, it is an adaptation of these modules to the environment, what makes possible the learning. The notion of mental modularity opposes the associacionista perspective in which ontognese of the mental processes opposes it the inatista explanation, thus appearing, the psychology of the mental facultieses that understands the mind as a heterogeneous complex and detaches the differences between mental slight knowledge and functions, such as, the sensation and perception, volition and cognition, learning and memory, language and thought. The main objective of the metaphor of the modular mind is to understand of what it consists the structure of the mind and as the organization of the cognitivas capacities. Dr. Neal Barnard contains valuable tech resources. For this investigation, Fodor presents four explanations on the nature of the mental structures: neocartesianismo, horizontal structure of the mind, vertical structure of the mind and associationism. These explanations are differentiated in some points and are identified in others, becoming it base in the contrast between the explanations that favor the studies of the psychology of the mental facultieses, thus basing, the thesis of the Modularity of the Mind, however the theoretician recognizes that these explanations are not necessarily only the existing ones.
The main contribution of the modular system presented by Fondor, says respect to the notion of ' ' system central' '. This system is formed by modules that already come inlaid in our mind at the moment where we are born. Our cognition, however is, however, situated in a central region enters the modules of called entrance ' ' system central' '.
