Only after the last tree to olo cortado.S after the last river is poisoned. S olo after the last fish is caught. Only then will you know that money can not eat. Indian Prophecy. Frequently Rick Garcia CBS has said that publicly. Increasingly it is alarming what might happen in the future to humanity that will not stop their growth, in the proper management of energy the effects this generated in its habitat, its use, because the consequences are already causing, where more and more damaging to their environment, endangering their survival. It is very important that countries through campaigns, actions, programs to engage their citizens, the world to cooperate with the responsibility of non-contamination and proper use of energy, to make a reality the preservation of species, if you really want to preserve an environment where people can live without fear of destruction. The problem is so serious that can not be avoided, while we remain in this dimension where we are forced to work with our media, advertising everything that can happen in order to provide greater evils. Hence the importance of remembering the remark brings us Gaia Vince, an interesting written on this topic Gaia Vince, published in New Scientist, where he describes the valid concern, that an average warming of the globe would make 4 C the world beyond recognition. In fact, human activity and has had such an impact that some people proposed to describe the period since the eighteenth century as a new geological era marked by human activity. “It can be seen as the Anthropocene,” says the winner of the Nobel laureate and chemist Paul Crutzen of the atmosphere, the Max Planck Institute, Germany.
The System of residues is as a computer and the statistics, has a continuous flow with entrances or input of the data, that are the source or origin of the residues, the way or phase of guiding and processing given them that they are the collection and the transport of the residues and the exits or output of the data that are the presentation of the given ones or discarding and/or disposal end of the residues in the case. Thus the importance always to compile and to collect given statistical for a management of the residues. Thus I show below the synthesis of the data, not as inference for a population universe, but yes as norteadoras statisticians of a route for the hospital administrators. I also clarify the aspects statistician-mathematicians of the hospital residues are mentioned in subitens 4,2 and 4.2.1 and 4.2.2 and 4.2.3 of the Resolution of Direction Student body RDC n 306 of the Anvisa that deals with minimum pointers (tax of accidents with residues perforate-cutting, variation of the generation of residues, variation of the ratio of residues of the Groups, B, C, D and and variation of the percentage of recycling) in its chapter V? Plan of Management of Residues of the Services of Health? PGRSS. A hospital together with other services of health answers for 1% 3% of all the residues produced in the city. Thus it does not represent Ambient Liabilities, as many want to boast. On the basis of given hypothetical that if approaches a little of the reality of a hospital x of great transport (n of stream beds > or = 150 and 500 surgeries/month), esteem in 2.000 people/day (between interned, accompanying patients, visiting, atendimentos ambulatoriais of less 24-hour of permanence, servers and employees of rendering terceirizadas companies of services and/or suppliers) the flow in this unit of health.
The plastics, when they are changedded into residues, can be valued, of form to be able to again come to be useful. The plastic recycling is a process of product quality, that is, of the quality of the residues for the systems of selective collections.
The conversion of the plastic residues in small grains that can be reused in the production of other products these plastic residues for stages, such as triturao, laudering, drying and granulation, the plastics if divide in two important categories, represent in surround 20% of the total consumed in the country, are the termosfixos and the thermoplastic ones. One of the durable materials most useful and known by the man is the plastic being the used material more in the modern world, but facing severe you criticize of impact in the environment. Through it, we protect our foods and the storage of the same ones, we brush teeth with it, the cooling ones in plastic bottles, computers, cellular, plumbing, in summary this in all the place, does not obtain to imagine the life without it. Being consumed frightfully in millions of tons, most this being sent for sanitary aterros and to another part simply play is, poluindo sources, the rivers and until the seas, (OLIVER, 2007). Through these plastic, ambientalistas data a movement was formed anti- alleges that we can live without it, but still is esteem that a million of birds dies and one hundred a thousand mammals per year, for will eat or be imprisoned in plastic objects. Also on the health human being it foresees that a used product in the plastic containers in the microwaves, call (BPA) this causing clutters in the women, as endometriosis, cysts in the ovrios, fibrides and cancer, on the Tereftalato Polyethylene, that is, to liberate di (2-etilhexil) ftalato that cause cancer in the human beings.. .
Everyone knows what a plastic. It so came into our lives and our way of life. What we have no idea of what would be done most things. But nobody thought about how it is harmful and how useful use? Let's take a closer look at the life of plastics in our environment. If you look around, in every room, kitchen, bathroom plastic surrounds us everywhere. Packaging, boxes, computers, containers for vacuum cleaners phones and toys and much more made of this substance. How does this affect our health and our children's health? There are some types of plastics, which are much harm to human health.
Polycarbonate contains a substance as bisphenol A. It causes hormonal disorders. Which subsequently leads to various diseases – cancer, endocrine and other resonant. Plastics can be divided into 7 categories. Determine what kind of Plastics made a particular subject can be making out the figure of a triangle, whose walls are shown as arrows. – Polyethylene terephthalate. It is made bottles for various products such as juice, sunflower oil, Ketchup and others.
As well as packaging for cosmetics. This kind of cheap plastic, durable and safe enough for our lives. – High-density polyethylene. Used for the manufacture of disposable tableware, cosmetics, gels, and bottles for shampoo, containers for cleaners, covers, bottles, boxes, packing bags and toys. They are also safe, durable and easy to recycle. Withstand relatively high temperatures – up to +110 C. – Polivinlhlorid. It is used in the manufacture of linoleum, window profiles, packaging, household appliances, iskusttvennoy skin film suspended ceilings, curtain for the shower. This type of plastic is off, but it is difficult to recycle enough and toxic. – Low-density polyethylene. From it produces packaging materials, bags, CDs. It's easy, cheap, is considered safe, although its production uses utan, benzene and vinyl acetate. – Polypropylene. It is made from buckets, bags, caps, packaging of certain products, and packaging of household appliances. Withstands high temperatures (up to 175 C). It is believed that it is safe. – Polystyrene. Used for Manufactured by the well-known to all disposable utensils, cups of yogurt, toys, insulation boards, packaging for eggs, and more. He is not strong, but fairly cheap stuff. It is believed that the polystyrene obtained polymerization of styrene, a carcinogen. – Other types of plastics. They are little known, because their use is dangerous to our health. Yet sometimes they are used in the manufacture of glassware, bottles, etc. So try to avoid plastic utensils, Better use porcelain, metal or glass.
The civil constructions had not left to have its space, each more increasing time in this problematic one. The diverse machines, equipment, products that are used in the constructions had gained space in the studies in what respect to the norms of protection to the environment is said. What still it passes for studies is the sonorous pollution, the level of these civil constructions, therefore not only the equipment is the responsible ones for the noises, but normal actions of the worker, as ousting, locomotion and manual processes of the diverse utensils of the workmanships. 2. BIBLIOGRAPHICAL REVISION MACHINES AND EQUIPMENT Machine is all mechanical or organic device that executes or aid in the performance of the tasks, depending for this on a power plant. They can be of the light, average or weighed types, and also can, play some functions, as in agricultural industrial applications and pavements.
Already equipment is a device in itself, as a whole, used in the execution of a task or service. Examples: Wimbles, similar parafusadeiras and, electronic computers, and equipment, diverse tools, diverse machines. As some components of machines, we can cite the gears, the mechanisms, the engines amongst others. CONCRETE TRUCK MIXER a batoneira, concrete truck mixer or mixer of concrete is the equipment used for mixture of materials, in which if they add loads of rock, sand, cement and water, in the ratio and which had texture, in accordance with the type of workmanship. The criterion of the civil engineer can be increased other material types, as diverse types of cements and rocks, or additives. She is very used in the civil construction, mainly, for mixture of added as products and substances cousins the example in the construction of barrages and dams using itself the concrete in the mixture of the mortar. For having different composition, not being added the rock and being able themselves to add the hidratada whitewash, this is more used in covering, rejuntamentos and other preparos in the workmanship.
In the year of 1993 for about 5.900 Ha. in 2004 (LOYAL BASTOS & IT HISSES, 2004). In function of this increase of demand for water in the region, the number of perforateed tubular wells in the region passed of 1.000 wells in the end of decade 70 for about 6.000 in year 2004, being about 70% these wells currently in activity (BASTOS LOYAL & IT HISSES, 2004). In last the 50 years the world-wide population passed of 2,5 billion people for 6,1 billion. They is esteem that up to 2050 the planet has between 9 and 11 billion inhabitants. With this population growth, the demand also grows for foods, for energy, mineral water and resources, also increasing the pollution and the ambient degradation. Currently the ratio of area cultivated for person fell of 0,24ha/pessoa in 1950 for 0,12ha/pessoa in 2000.
It is calculated that in 2050 the ratio will be of 0,08ha/pessoa. The agriculturvel land is each scarcer time and the biotechnology already proved not to be efficient in the increase of the productivity. The life started with the water and the lack of it can extinguishing in them. According to ONU, up to 2025, two billion and seven hundred million people go to suffer severely with the water lack. The man is the great water consumer candy, on average is used 200 liters of water/day/person, in approach numbers. One knows that the consumption of a family in the city is six times bigger that of another family in the field, however, the water consumption in agriculture is responsible for 70% of the world-wide total. A sanitary discharge is equivalent the twelve liters, and to wash an amount of clothes in the machine, the approach consumption is of 120 liters. One kilo of meat corresponds the 18,000 liters of water that had been supplied direct or indirectly to the animal that gave origin to it, until the meat to be ready for the consumption.
