Topobatimetria e geração de modelo digital de terreno no monitoramento da dinâmica fluvial do ribeirão Guaratinguetá

This research was developed with the goal of creating a Digital Terrain Model(DTM),through a topo-bathymetric data gathering that allows the monitoring of the fluvial dynamics of part of Guaratinguetá’s creek, where preliminary evaluations identified, in a short period of time, intense changes on its riverbed. Modern topography technics and tools were used for the data gathering, such as the use of geodesic GPS and Total Station. The DTM was primal for the project e execution of the desilting works of the researched part of the creek, being used to estimate the amount of soil to be moved. The comparison between the digital terrain models generated before and after the desilting has showed the efficiency and aplicability of this technique in the monitoring of the fluvial dynamics changes of Guaratinguetá’s creek

Proposta de recuperação e manejo de nascente em área rural do município de Álvares Machado – SP

The lack of proper planning in intervention works of runoff water on rural properties and rural public roads leads to economic damage and loss of environmental quality. The impact of the action without technical base is soil erosion, siltation of water sources, loss of the quality and availability of water, invalidating areas for cultivation and livestock. The conservation of headwaters requires beyond regeneration of the environmental characteristics the repair and management of the degraded watercourse in order to control erosion. This graduate work in Environmental Engineering from Universidade Estadual Paulista Julio de Mesquita Filho - UNESP Presidente Prudente proposes a headwater recuperation and management in rural area of Álvares Machado municipality, São Paulo State, through the method of deep drainage applied to the case of a rural road near the outcrop of water. This technique consists in the installation of draining structures in sub-areas of the road surface, or sub-gutter and/or in the platform border in order to conduct the underground flow of water and reduce the loss of sediment in water flow. Therefore, was performed a historic study of use and occupation of land in the municipality of Álvares Machado, portraying transformations of the landscape caused by human action. Geology, geomorphology, pedology and hydrogeology data were collected from the study area in order to establish the conditions that led into the current situation of degradation and formulate an effective intervention strategy for civil works

So in general we can say that this ... (Complete abstract click electronic access below)

Reparação de enxertos ósseos autógenos recobertos ou não por membrana de ptfe-e em ratas ovariectomizadas. Estudo histológico e histomorfométrico

Abstract : The objective of this study was to evaluate quantitatively and to describe qualitatively the process of bone repair in the interface of receptor bed and graft autogenous bone block with or without a e-PTFE membrane, in osteopenia induced rats. To this end, we used forty-eight Wistar rats weighing about 300g, in which, with the aid of 4.1 mm trephine a graft was removed from the parietal bone and fixed to the surface of the left mandibular ramus. The animals were randomly divided into four experimental groups: Group 1 (n=12): SHAM operated and autogenous bone graft only; Group 2 (n=12): SHAM and autogenous bone graft covered by e-PTFE membrane; Group 3 (n=12): ovariectomized rats (OVX) and autogenous bone graft only; Group 4 (n=12): OVX and autogenous bone graft covered by e-PTFE membrane. The animals in each group were sacrificed at three time periods: 21, 45 and 60 days, each time with 4 animals per group. The specimens were decalcified and included, the sections were stained with HE and subjected to histological and histomorphometric analysis in light microscopy. The results of the ANOVA showed that the variables on the condition (OVZ and SHAM), and the time (21, 45 and 60 days) were statistically significant, and can be established with the Tukey test (5%) that the period 21-day differs significantly from the periods of 45 and 60 days, which did not differ among themselves. The descriptive histological analysis showed integration of the graft in all animals. It was concluded that the initial integration of the graft bed was negatively affected in the presence of induced osteopenia, and that the use or not of a e-PTFE membrane did not interfere in the process of integration

Implantes curtos em região posterior da mandíbula

The rehabilitation of edentulous areas with osseointegrated dental implants is a well-documented, predictable procedure in the literature, with high success rates. However, the lack of bone at the recipient bed or proximity to anatomic structures limits the rehabilitation procedure especially at the posterior mandible. Thus, short implants are an alternative treatment for such cases of severe bone resorption. The purpose of this study was to review the success rate of short implants, especially those based in the posterior mandible and to show a clinical case. A literature review was made on electronic databases PubMed and Bireme with articles published between the years 2005 to 2012, using the keywords "short dental implants". It was concluded that the success rates of short implants are similar to those presented by conventional implants but still related to their geometry and surface treatment. Also, short implants can be considered as a viable alternative for the rehabilitation of severely resorbed jaws. However, many authors consider that more research is necessary when a short implant is compared to a long dental implant.

Inorganic and organic trace mineral supplementation in weanling pig diets

A study was conducted to evaluate the s of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in five treatments: control diet (no added trace mineral premix); 50% ITMP (control diet with inorganic trace mineral premix supplying only 50% of trace mineral requirements); 50% OTMP (control diet with organic trace mineral premix supplying only 50% of trace mineral requirements); 100% ITMP (control diet with inorganic trace mineral premix supplying 100% of trace mineral requirements); and 100% OTMP (control diet with organic trace mineral premix supplying 100% of trace mineral requirements). Feed intake and daily weight gain were not affected by treatments, however, piglets supplemented by trace minerals presented better gain:feed ratio. No differences were observed at calcium, phosphorus, potassium, magnesium, sodium and sulfur excreted in feces per kilogram of feed intake. Treatments did not affect calcium, phosphorus, magnesium, sulfur and iron content in metacarpals. Trace mineral supplementation, regardless of level and source, improved the performance of piglets.

Use of the probability of stone formation (PSF) score to assess stone forming risk and treatment response in a cohort of Brazilian stone formers

Introduction: The aim was to confirm that PSF (probability of stone formation) changed appropriately following medical therapy on recurrent stone formers.Materials and Methods: Data were collected on 26 Brazilian stone-formers. A baseline 24-hour urine collection was performed prior to treatment. Details of the medical treatment initiated for stone-disease were recorded. A PSF calculation was performed on the 24 hour urine sample using the 7 urinary parameters required: voided volume, oxalate, calcium, urate, pH, citrate and magnesium. A repeat 24-hour urine sample was performed for PSF calculation after treatment. Comparison was made between the PSF scores before and during treatment.Results: At baseline, 20 of the 26 patients (77%) had a high PSF score (> 0.5). Of the 26 patients, 17 (65%) showed an overall reduction in their PSF profiles with a medical treatment regimen. Eleven patients (42%) changed from a high risk (PSF > 0.5) to a low risk (PSF < 0.5) and 6 patients reduced their risk score but did not change risk category. Six (23%) patients remained in a high risk category (> 0.5) during both assessments.Conclusions: The PSF score reduced following medical treatment in the majority of patients in this cohort.

Relative bioavailability of iron from organic sources for weanling piglets

Some authors consider minerals from organic sources more bioavailable for pig nutrition in comparison with inorganic sources. To evaluate the relative iron bioavailability from the organic source iron carbo-amino-phospho-chelate (ICAPC) to weanling piglets, it was conducted an experiment with 126 commercial piglets, using iron sulfate monohydrate (S) as standard. The experiment had a randomized block design with seven treatments (diet without adding specific source of iron, diet with 50, 100 and 150 ppm iron from S and diet with 50, 100 and 150 ppm iron from ICAPC), six replications and three animals per experimental unit. Performance parameters (average daily gain - ADG, feed: gain ratio - F:G) and blood variables (hemoglobin - Hb, hematocrit - Ht, transferrin - TR, latent iron-binding capacity - LIBC, total iron-binding capacity - TIBC, serum iron - Fe and transferrin saturation index - TSI) were evaluated. At the end of the experiment a piglet from each experimental unit was slaughtered and its liver and spleen removed for assessment of iron concentration by flame atomic absorption spectrometry (FAAS). The evaluated sources of iron yielded similar results for the variables of interest, but the increase in iron intake was followed by a linear increase in ADG, Hb, Ht, Fe and TSI as well as a linear decrease in the values of F:G, TR, LIBC and TIBC. Iron bioavailabilities from both ICAPC and S sources are similar for weanling piglets.
