The remaining portion of the semblante if conserve in the natural state … ' ' . questions. (LEBRUN, 1837, p.12) I was divided in studies on the Osteologia, of the Miologia and the Philosophy of the passions. David Karp has much experience in this field. The first part brings study on the Osteologia. It folloies, after that, taboas on the skeleton and later on the miologia. After that, the compendium still deals with the Physiology of the passions and, general consideraes on the study of the ratios of the human body. According to Elaine Days ' ' the workmanship is composed of the main related artistic theories to the anatomy used in the Acadmie Royale de Peinture et Sculpture in century XVII, even so has a small relative part to century XIX happened of the dictionary of Millin, giving special emphasis to the questions of propores' ' . The application on the part of the pupils of these theoretical and practical subsidies gave to consistency in the elaboration and molding to them of three-dimensional workmanships bi or.

From there, the necessity of the studies of Alive Model, Anatomy and Physiology of the Passions. The sculptor has for obligatoriness, to know the mechanism of functioning of the anatomy human being. He has since the Renaissance, many artists of the time already had shown interest for the study of the human body.

BIOFSICA OF THE HEARING

The object of study of this work, the auditory device of the mammals and the human beings, is a system with mechanisms that if relate between itself, converting mechanical stimulatons (mechanical waves) into information for the brain. These information are processed for the brain in form of electric impulse, where they cause the psicofsica sensation of the hearing. Beyond allowing the perception of the sounds, the hearing has also the capacity to transmit messages emotional, activating other directions and areas of the brain, being also of basic importance in the balance and position human being and as felt of localization of some animals. Since the insects until human beings, the sound is a precious agent of information communication, therefore can be observed the internal specialization of the auditory device and its structures. The methodology used in the elaboration of this work was the bibliographical revision and searches in half electronic.

The general objective was to understand of a general form the biofsico functioning of the auditory device, its functions, the internal phenomena and importance of this direction in the perception of the external stimulatons. The specific objectives had been: To summarily describe the physics of the sound; To describe some characteristics and properties of the sound; To describe the auditory device of the man and other mammals; To understand the structure and functions of the auditory device; To understand the types of anomalies of the hearing; To describe the ecolocalizao through the system of PHYSICAL hearing OF the SOUND a direct and common definition of characterizes it to sound as a material disturbance that if propagates through ondulatrios and longitudinal impulses, known as mechanical waves. Inside of its gamma of wave length, the mechanical waves are used as media for diverse species.. Further details can be found at Dropbox, an internet resource.

Magnetic Resonance

Amino possesss on carbon sp3 nitrogen (C? N), what it leads to an absorption in d 40,00. In nitrilas, the carbon atom sp absorbs in d 115 ppm. The RMN specter 13C? DEPT (intensification of the distortion for polarization transference) is used in the determination of on the hydrogen atom number 13C. Logically, hidrogenados carbon atoms do not present signal, in this type of specter. DEPT 135 shows signals for low (indicating metilnicos carbons) and signals for top (indicating metnicos and methylic carbons). In DEPT 90, only signals appear of groups CH.

In the specter of RMN 13C of the etanoato of etila, the signals in d 15 and 30 corresponds to methylic carbon atoms and the signal in d 60 corresponds to metilnico carbon. The carbon atom of the group carbonila has signal in d 170. The RMN specter 13C? DEPT shows a signal for low (d 60), therefore indicates metilnico carbon, and the signals in d 15 and 30 for top, therefore they indicate methylic carbons. In this specter, the referring signal to carbonlico carbon is not verified (in d 170), since it is a carbon not hidrogenado. With this study of the RMN, it was verified that one ' ' aumento' ' of the electronic density on determined atom of hydrogen or carbon-13 it implies in ' ' reduo' ' of the value of the chemical displacement of the same (effect shield). For in such a way it is necessary to know some groups that intervene, of certain form, in the electronic density. This fact is marcante in benznicos rings, with the positions orto, goal and stops. Groups that ' ' doam' ' electrons for the ring (positive effect mesmero) increase, in this, the electronic density, in the positions orto and stop of the ring.

They are examples of these groups: amino, hidroxila, metoxila and alquilas. Groups that ' ' retiram' ' electrons of the ring (negative effect mesmero) diminish, in this, the electronic density. They are examples: nitro, sulfnico, carboxila and aldoxila. To classify them in orto/for leading controllers and goal is to take in consideration the reacional question (reactions of substitution in the ring). Much can be explored of the Nuclear and applied Magnetic Resonance in diverse areas (chemical organic: natural synthesis and products; pharmacy: pharmaceutical chemistry and quality control; vegetal biochemist, among others) being of much importance its knowledge.
