Avaliação morfométrica, realizada pelo exame ultrassonográfico, da veia porta, veia cava caudal e aorta abdominal em cães saudáveis de diferentes pesos corpóreos

The diameters and areas of portal vein, caudal vena cava and abdominal aorta are useful measurements in dogs. These values can be easily measured by ultrasonographic exam, and variations of normality can be an important indicator of hepatic or extra-hepatic alterations. This study aimed to measure the diameter and areas of portal vein, caudal vena cava and abdominal aorta in healthy dogs, with normal corporal score, divided in groups according to the body weight, and assess whether the data are influenced by animal weight. Thirty dogs were examined and divided into three groups (Group A: ≤ 10 kg Group B: from 10.1 to 20.0 kg; Group C: ≥ 20.1 kg). To measure the diameters and areas of portal vein, caudal vena cava and abdominal aorta, the animal was kept in left lateral decubitus position and the transducer was placed on the right lateral abdominal wall, at approximately the 10 th or 11 th intercostal space, in the porta hepatis region. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta were significantly lower for dogs in Group A with respect to other groups and the dogs from Groups B and C had similar results with each other. The diameters and areas of the portal vein, caudal vena cava and abdominal aorta may vary with the animal size, and reference values must be specific for small, medium and large dogs.

Maltodextrina em rações de leitões desmamados com diferentes pesos: Desempenho e morfometria intestinal

Two trials were conducted: in the first trial, 96 weaning pigs at the age of 21 days were used, in a block design, with a 2 x 2 factorial arrangement (two sources of carbohydrate and two weaning weight classes). In the second trial, 48 pigs were used, in a block design, with 2 x 2 x 2 x 3 factorial arrangement (two weaning weight classes x two sources of carbohydrate x two portions of the small intestine x three slaughter periods). The effects of the replacement of lactose by maltodextrin in diets of weaning pigs, with different weights, were evaluated on daily feed intake, daily weight gain, feed:gain ratio, villus height, crypt depth and thickness of the mucosa. In the first trial, from 0 to 17 days and from 0 to 29 days after weaning, effects of weight classes were detected on daily weight gain and daily feed intake. In the second trial, maltodextrin resulted in an increase in the average thickness of the intestinal mucosa and in average crypt depth, only in lighter animals. Maltodextrin can be used as an alternative to lactose in diets of weaning pigs.

Reprodutibilidade de medidas antropométricas estáticas de graduandos de odontologia e de mochos odontológicos

Objective: To evaluate the intraexaminer reproducibility of static anthropometric measurements of undergraduate dental students as well as the characteristics and regulating measurements of the dental stools used by them. Methods: Forty volunteers and 6 types of dental stools were evaluated. For the anthropometric measurements the employed equipments were: an adapted office chair, aflexible measuring tape with two adapted rods, a metallic device with a 90 degree central angle, string, a 35 x 24 cm rectangular wooden board, isolating tape and crepe tape. In order to standardize the position of the adapted office chair and the volunteers' feet, the floor was marked with the isolating and crepe tapes. A string was attached to the waist of each volunteer to mark the area corresponding to the kidney region making it possible to measure the seat-renal region area. The examined anthropometric measurements were height, trunkcephalic heigh, sacral-popliteal distance (OK?), hip width, popliteal height and the seat-renal region height. The evaluated characteristics of the dental stools relative to the seat were depth, horizontal width and minimum/maximum height. The back of the dental stool was evaluated as for the minimum/ maximum height adjustment. The anthropometric and dental stool measurements were obtained by a single examiner at two moments with a 1-week interval between the evaluations. Intra-class correlation coefficient (ρ) was used to estimate the intraexaminer reproducibility. Results: Excellent reproducibility was observed for all anthropometric measurements obtained (ρ=0.99) as well as for all dental stools evaluated (ρ=0.99). Conclusion: The method used to obtain the anthropometric and dental stools measurements was reproducible and can be used reliably.

Sistema para realização de medidas de luminescência com excitação por raios X

In this work is presented a versatile system for X-ray excited optical luminescence (XEOL) measurements. The apparatus was assembled from a sample holder connected to an optical fiber responsibly for the acquisition of the scintillation signal. The spectrum is registered with a CCD coupled in a spectrograph provided with diffraction gratings. The system performance was analyzed by exciting GdAlO3:Eu3+ 3.0 at.% with X-rays from a diffractometer and measuring the emission spectra. The system can be used to obtain precise and reliable spectroscopic properties of samples with various conformations without the loss of the required safety when dealing with ionizing radiations.

Estimativa do tempo de produção de chorume em aterro controlado por meio de medidas de resistividade elétrica

Landfill is an engineering work that aims at to accommodate residues in the smallest possible space in the soil, with minimum damages to the environment and the public health. One in the constructive forms of a controlled landfill is the excavation of ditches with appropriate dimensions, for disposition of solid residues without compactation or impermeabilization. Liquid effluents generated for similar volumes of residues, disposed in ditches with ages different from closing, it should result in physical and chemical alterations you correlated at the time of residence materials. With base in this hypothesis, measures of electric resistivity were accomplished through the of Eletrical Resistivity geophysical method, on residues ditches closed annually between 12/2001 and 12/2007, localized in control landfill of the Cordeirópolis city (SP). The leachate is a liquid effluent generated by the decomposition of organic matter and characterized by high content in total dissolved solids, whose interaction with geological environment results in alterations in terms of electrical resistivity susceptible to detection for the geophysical instrumental. The results suggest a resistivity reduction for leachate percolation produced for ditches recently and increase progressive of the resistivity for older ditches. The statistical comparative analysis with reference values for the area suggests ages of the finish production and percolation leachate for soil and rock below the ditches.
