Imaging diagnosis is a medical specialty that uses imaging techniques to perform diagnosis. In diagnostic imaging various methods are used such as direct absorption of photons - SPA and DPA, radiographic photometry, the dual-energy radiographic absorptiometry - DEXA, ultrasound, magnetic resonance imaging, computed tomography and optical densitometry in radiographic image. The dog can be considered one of the most widely used animals in the study of bone diseases and searching for a reliable diagnosis, although not an ideal model for the study of osteoporosis, because these animals tend not to develop a decrease in bone mineral density. The objective of this study was to analyze bone density in mongrel dogs from the determination of the variation of density along the radio-ulna bone and also the mean value related to gender, weight and age of individuals. The density analysis carried out showed that for this data set, there is a significant difference in the case of gender and age of the animal and may generalize according to these variables. The only significant difference was found in the weight, which increases bone mass is related to weight gain through the growth of the animal

This research aims to discuss the division of royalties from a legal perspective and its substitute role towards the non-taxation at source, in other words the taxation of destiny at the Brazilian petroleum industry. The analysis aims to deal with the historical evolution in relation to the aspect of royalties’ payment and its deviation of compensatory character in order to supply the ICMS function. There are some specific study objects in this research: 1. how the transformation of royalties’ payment led to financial compensation; 2. to whom the transference of mineral rent belongs – to the UNIÃO or to the fortunate regions which the oil is extracted; 3. would a tax reform be enough to minimize the competition of States and Cities towards the royalties? The research aims to clarify the real expectation that States have on the royalties’ payment. There is no compensation for damage to the environment as it is stated by the initial characteristic of the Constitution, and, by the contrast, from a compensatory character, there is a lacking of taxation from the sector mentioned before, this fact damages the producing states checked out by this research

The focus of this research study were gas exchange between soil and atmosphere of nitrous oxide (N2O) between different fertilization treatments Corn The research, conducted in the experimental field Dedelow - Brandenburg / Germany, analyzed three different fertilization treatments, aiming to quantify GHE emissions, to identify the influence of the residue of biogas in the release of these gases process in agricultural soils in search for a solution fertilization less harmful to the environment and the greenhouse effect , based on the comparison of three treatments: organic fertilization, mineral fertilization and no fertilization. It was found through the analysis of the measurements that the first was the one which issued N2O, showing that even though coming from the residue of biogas , when returned to the soil, it becomes harmful to the environment and global warming . The cultivation of energy crops can lower or raise the emissions of greenhouse gases, so it is necessary for further research on this question not only in Germany , where such research is in continuity, but also in Brazil, a pioneer in the introduction to his energy matrix of a biofuel produced from cane sugar

This study used histomorphometric analysis to investigate the effect of sodium alendronate, used for the treatment of osteoporosis, on the repair of surgically-induced bone defects in the tibia of castrated rats. Methods: The castrated animals were given subcutaneous injections of sodium alendronate (0.7mg/Kg) diluted in saline once a week; the control animals were given the same dose of saline. At 16, 30 and 44 days after the first injection of sodium alendronate, the animals were sacrificed and the right tibias were removed and processed for histomorphometric analysis. The volumetric bone mineral density was estimated by a reticular grid (25 points) attached to a light microscope. The number of points on the bone tissue was counted in the histological sections, totaling 100 points/animal. Results: The results revealed that sodium alendronate stimulated bone formation in castrated rats in all occasions, mainly at 16 and 30 days. Conclusion: Sodium alendronate affects mineral homeostasis, promoting bone repair.
