Aluminum Sulphate

To work this subject the one is important to stand out the end that if considered and if the same it is justifiable for one better agreement of these processes. Thus being she is necessary to take in account some elementary concepts and consideraes for one better understanding of the considered subject, starting with substances, for example. ' ' The samples of substance that we remove generally of the nature are mixtures and are important to know the components that forma' ' (SARDELLA, 1 999). These basic concepts will be basic for such understanding, thus: substances and mixtures are. – substance: chemical species with physical properties and chemical fellow creatures. Teva shines more light on the discussion.

Former: Oxygen (O2) and Iron (Faith). – Mixture: set of chemical species that present different physical and chemical properties, which can be: Homogeneous when they present one only fase' Former: Chloride of Sodium (NCl) and gua (H2O) and heterogeneous when they present more than a phase, Former: Water (H2O) and Sand – (silica oxide, SiO2). With the thematic separation of Mixtures, another important subject that it can be focused is water and its treatment. In this aspect the separation processes can be work such as: filtration, sedimentation or decantation flocculation. – Filtration: mechanical process that serves to unfold heterogeneous mixtures of a dispersed solid in a liquid or gas.

Former: Solid particle separation of the coffee (FELTRE, 1996). – Sedimentation or Decantation: mechanical process that serves to unfold heterogeneous mixtures of a solid in a liquid or two imiscveis liquids between itself. Former: Mixture of water and sand (FELTRE, 1996). According to Feltre (1996), flocculation is the process used in the ETAS (Stations of Water Treatment) where if dissolves Aluminum Sulphate (Al2 (SO4) 3) and hidrxido of Calcium (Ca (OH) 2) to hold back contained solid particles in the water (FELTRE, 1996). Water can inside also be focused of the subject, wastefulness and its pollution.

University Vector

It only has chronic cases of the illness. With regard to the treatment it was informed that medicine ROCHAGAN more is not used due to prohibition of the same for the Health department, that alleges collateral effect. In this in case that a medical accompaniment is made. With regard to the work carried through for the monitoring epidemiologist the visit in the residences is only made when it has notification of the presence of the vector or when the illness is diagnosised. In this in case that the agent ones go until the residence look for the vector, in case that they find the vector, they collect the sample and they direct for analyzes and later they spray insecticide the residence.

As we can conclude that due the eradication to be in its controlled totality, the sanitary monitoring of Murtinho Port directed the attention for focos of other illnesses, a time that the Illness of Chagas in the city is with a mapping that provides a general vision of the situation.

Therefore It hisses standes out: During the pertaining to school period, the pupil is forming its critical identity and its capacity to argue and to create. In this phase of its life, it its concept will be elaborating on the world, and its necessity to extend its knowledge and to find answers for the doubts acquired in classroom must be supported by the available resources in the pertaining to school library and the aid given for the librarian. When disponibilizar the access to the information and instructing in search of connection in other sources; the librarian will be creating a laboratory of information through a pedagogical environment, that is much-needed for the pupil, how much the necessity to attend the content programmarian given in classroom to develop its logical reasoning on a specific substance or activity of research. Thus, the pupil will have to find the theoretical referencial in the library that he will make possible to create coherent opinions, reflexivas and critical that will enrich its participation and its accompaniment of the lessons, at the same time that he will increase its capacity to relate the learning of the school with its daily life (HISSES, 2005, p.125 and 126). The PERTAINING TO SCHOOL LIBRARY IN the CONSTRUCTION OF the KNOWLEDGE the pertaining to school library during much time was seen as local of punishment, where the pupils badly held were ordered to reflect on its action and behaviors.

However, the library is a place of construction, the constant construction of the knowledge.

Chaos and Radiation

The maximum celebrity of precursory Lorentz of the theory of the chaos, that &#039 says; ' Beating of wing of a butterfly in Brazil can cause an hurricane in the Texas' ' , also she is valid in radiology. In radiology, that is the part of the medicine that uses the ionizing radiations for disgnostic ends, can occur damages to the person who to receive this radiation, a time such radiation has as characteristic to ionize – to pull out atom electrons, what the molecule configuration can desestruturar, implying in real damages to the patient – as, for example, skin burning cancer. When a patient is submitted to a x-ray or cat scan, it receives a dose – amount from radiation in the part in question. Depending on the dose, two situations can occur: 1) has proximate damage or 2) have damage in long stated period. In the first one, we call determinstico effect, therefore it is determined by a dose threshold, that is, one has limited of dose in which it is certain that a damage will occur; in second, we call effect random, a purely probabilist effect, where the person can or not suffer a damage.

Let us emphasize the random effect. In such effect, as the proper name says, it has a stockage; storage of dose in the patient. Throughout the years, a person is submitted to one determined amount of examinations that use the ionizing radiations. In each one, it receives a dose from radiation characteristic of the examination? in a hand x-ray, the dose is minor who in one of thorax, that in turn is minor who a cat scan of any part of the body. This dose goes being ' ' armazenada' ' in the body, increasing the probability to unchain a cancer throughout the years. But as is a probabilist effect, a person can carry through an examination of hand x-ray? what is one of the techniques with lesser level of dose and to have cancer, or to carry through a cat scan examination? that it has high dose and not to have cancer. If one may use the expression in radiology: ' ' it is a lottery that nobody wants ganhar' '. The fact of that a small dose can unchain a cancer, corroborates with the principle of Lorentz.

The small dose would be the butterfly beating its wing, and the hurricane, the cancer. We have that to also lead in account, the call radiation of deep, that is that proceeding one from the cosmic space and of the nature to our redor, that for minor who is also can unchain cancer. If one the person to the 20 years, is submitted to a x-ray any, and to the 60 it develops cancer, this can have exactly been caused forty years behind. If it had not carried through that x-ray and taken that small dose, she would not have cancer. We conclude then, that the taken dose has forty years was the sufficient to unchain the cancer. Obviously, the cancer has many other factors associates who not them ionizing radiations, but this presented possibility real and is justified by the random effect. In the truth, any dose that a person receives, exactly being proceeding from the deep radiation of or radiological examinations, increases the probability to develop cancer. But, for to be a probability, a person can receive high doses throughout the life and nothing to happen
