In the electromagnetic specter, the region of frequency understood between 3 x 1012 Hz and 4,3 x 1014 Hz corresponds to the infra-red ray (IV). When this radiation is absorbed by a organic composition molecule, occurs ' ' deformaes' ' in the linkings between constituent atoms of the composition. The analysis of a specter gotten for absorption in the infra-red ray is of much value for the study and the briefing of the chemical structure of a substance (either gotten it of a medicine, of a vegetal extract, one shows ambient, of a chemical reaction). The region of the specter understood between frequency 4000 cm-1 and 625 cm-1 presents importance for Organic Chemistry. The deformations suffered for the chemical linkings, in result of the absorption in the infra-red ray, are perceived through vibracionais movements in the linkings, which involve angular deformations (in ' ' ngulos' ' of linkings) axial deformations (in the axles of the linkings). Of this form, the movements are found: stretching (symmetrical and anti-symmetrical), shears, twist, wag and rotation. In the Co2 molecule (carbonic gas), are verified angular deformation (= C =) in frequency 667 cm-1, while in the water molecule, occur angular deformation of linkings (H? H) in frequency 1595 cm-1.
Can be verified symmetrical axial deformation in the linkings of (H? H) in 3655 cm-1 and anti-symmetrical in 3755 cm-1. In this last case, in the water molecule, it is calculated that the axial deformation of each linking? H, corresponds to the frequency 3700 cm-1, a value ' ' intermedirio' ' between the two last ones. For Organic Chemistry, it does not interest the analysis ' ' complete and detalhada' ' of specters IV, many bands of absorption are ' ' desconhecidas' ' or they are ' ' desprezadas' ' , however frequencies of absorption of functional groups that matter, in the structural briefing, are taken in consideration, being compared with gotten data of other specters (others techniques) and with one ' ' biblioteca' ' data base of standards previously analyzed.
That ended our trip. During three weeks aboard the yacht-tri 'Crab', passed under sail more than 350 km from the small village of measured, on the banks of Kama, near Kazan, to the outskirts of . To be honest, the weather We did not indulge. The first week of a very strong head wind and big waves, we could not pass the area of the Kama mouth, of one of the most extensive areas of the Volga near Kazan, the width of the river is 30 km. Wind ripped off the foam with white lambs waves in some places lost sight of the shore – a full sense that you are at sea.
However, most mobile option for the working world in the kitchen is a lamp to 'Pin'. No responsibility: support – does not fit – took off. Brilliant! Lighting kitchen and dining room Modern kitchen are reasonably free approach to planning. Working the front does not need to be extended along the walls, it can be located, for example, in the middle of the room. In this way, can be created quite a lot of layout options – from a narrow high-tops for food 'on the move' pending in the center of the kitchen equipment. Such a plan requires a certain approach to the coverage as a location for the lights, but the ceiling does not have enough. Axis lighting shall not extend beyond the contour of the working surface, and best of all, if they intersect with the axis of the tabletop. The light from the hanging lamp should not be hit in the eye, so the scattering 'milk' or metallic shades in this case are the best solution.
Needless to once again talk about the eastern originality and scope of the project, organization and holding of Beijing xxix Olympic igr. of architectural grandeur, it is worth remembering that the Olympics games – is first and foremost, all athletes around the world in various disciplines. In total, 906 medals of Olympic athletes claimed 10 700. And it would be impossible without high-quality sports surfaces, special sporting and komplektarnogo .Stadion 'Bird's Nest', built in Beijing specifically for the Olympic Games-2008, for 100 years .Bolshoy interest functionaries, athletes and awareness of this structure is explained by the fact that athletics – it is the most medal sport in the Olympics (47 sets of medals). At this stadium, even long before its discovery and the Olympics, had already been registered the first record! This record was the company mondo. 6 specialists of the Company and 50 workers completed installation works in just 10 days, including the laying of 16,000 sq.m. Athletics coverage Mondotrack ftx and drawing layouts.
Inside of the school effective ways must be found so that each pupil understands the natural phenomena, the actions human beings and its consequence for I obtain, its proper species, the other beings livings creature and the environment. It is basic that each pupil develops its potentialities and adopts personal positions and constructive social behaviors, collaborating for the one construction society socially joust, in a healthful environment. The school inside of the Ambient Education must sensetize the pupil to search values that lead to a harmonious convivncia with the environment and the too much species that they inhabit the planet, assisting it to critically analyze it the principles that have led to the inconsequential destruction of the natural resources and some species. Having the clarity that the nature is not inexhaustible source of resources, its reserves are finite and must be used in rational way, preventing wastefulness and considering the recycling as vital process. That the too much species that exists in the planet deserve our respect. Moreover, the maintenance of biodiversity is basic for our survival. E, mainly, that it is necessary to plan the use and occupation of the ground in the urban and agricultural areas, considering that it is necessary to have worthy conditions of housing, work, transport and leisure, areas destined to the food production and protection of natural resources.
