Compreendido por um bloco (A) constituído de material metálico, possuindo quatro parafusos para fixar o sensor à estrutura, bem como possui grande resistência mecânica a deformação quando ocorre a inclinação da estrutura, de maneira que o bloco (A) está ligado ao bloco (B) por meio de parafusos internos, sendo o bloco (B) desenvolvido em duralumínio, o qual sofre a ação de grandes tensões provocadas pela sensibilização decorrente da existência de dois orifícios retangulares (E) passantes que criaram as regiões sensoras (rs1) e (rs2), sendo que em cada região sensora existem duas membranas laterais ao orifício, de forma que, devido a sensibilização das regiões (rs1) e (rs2)

Descrito como o presente Privilégio de Invenção, refere-se a um dispositivo para a fazer a medição dos ângulos de diferentes tipos de estruturas, para tanto o mesmo possui um corpo mecânico, formando um sensor de inclinação (1), composto por três partes onde, a primeira parte é a base (2), dotada de um par de orifícios (3), para a inserção de parafusos que fixam o dispositivo junto a uma estrutura qualquer.

The aim of this study was to evaluate the association between cryoprotectants little studied in Brazil such as dimethylformamide and trehalose amid thinner, using protocols of fast and slow defrosting. Three adult Labrador Retrievier male, healthy dogs, weekly submitted to one semen collection during five-weeks period, were used. The base diluent medium used in this study was tris-citrate added with 3% of dimethylformamide + 3% glycerol (D1), 3% dimethylformamide and trehalose (D2) and 4% glycerol (D3). At defrosting, half of the semen samples from each diluent medium was defrosted by rapid method in water-bath at 75 °C for seven minutes, followed by a new immersion at 37 °C for 1 minute. The other half of the samples was defrosted by slow method, in water-bath at 37 °C for 1 minute. The semen was evaluated for sperm progressive motility and vigor, besides membrane integrity. For this, the semen samples were submitted to either hyposmotic and membrane integrity tests of the plasmatic membrane and acrosome (fluorescence). The results indicated that the use of glycerol as cryoprotector in TRIS diluter provides greater efficacy in cryopreserving spermatozoa of the canine species, when compared to dimethylformamide associated with trehalose or glycerol.

This research presents the results of a cephalometric radiography study, in frontal norm, that was used to measure the possible linear correlations between several linear dimensions of the face, in a sample of a 140 caucasian brazilians, with an average age of 20 years, who were distributed in 2 groups as follows: Control group - formed of 35 males and 35 females, with no apparent facial deformities and with dental oclusion, not necessarily, in Angle's Class I; Unilateral cleft lip and palate group - formed of 35 males and 35 females with surgical correction of the up in the first year and of the palate until the third year of life, without orthodontic treatment. ln each teleradiography, the following parameters were measured using a computer: - Lateral orbit width or external orbit width (LOe) - Medial orbit width or internal orbit width (LOI) - Zygomatic width or facial width (LZI) - Mastold width (LMa) - Maxilar width (LMx) - Nasal width (LNa) - Condilar width (LCo) - Antigonial width (LGa) The values obtained were treated statistically using quantitative analysis (arithmetic mean, standard deviation, standard mean error, Person's variation factor and Pearson factor linear correlation). Theirs significance was established by Student's t test. The Pearson factor linear correlations determined between transverse linear cephalometric width dimensions of face in frontal norm for individuals of both groups and sex, with an average age of 20 years, were: ...
