Introduction: Infections are a major cause of morbidity and mortality in pediatric patients undergoing kidney transplantation (KT). Aim and Methods: To determine the patterns of infectious complications during the first 6 months post transplantation, we report our single center experience with data from pediatric kidney recipients transplanted between 2006 and 2011. Results: Thirty-two children (20 males) were submitted to KT. The most common cause of end-stage renal disease (ESRD) was congenital anomalies of the kidney and urinary tract (CAKUT) accounting for 62%. Over the first 6 months post-transplant period, twenty-eight (87.5%) children developed a total of 77 infections, mainly urinary tract infections (UTI) (64.9%). CAKUT etiology of ESRD and UTI before KT increased the risk to develop more than one episode of UTI [71.4% vs. 14.3% and 81.8% vs. 18.2%, respectively;p des had mild or moderate severity. No deaths occurred. Conclusion: A significant number of patients presented infectious complications during the first 6 months post transplantation. UTI are the most common type of infection, followed by viral infections, particularly CMV. Recognition, prevention and early treatment of infections are of major importance.

New recycling alternative for multilayer films was successfully presented. Food packaging formed from different materials is difficult to recycle. The use of aluminum, glass, paper, paints, varnishes, and other materials in the rolling processes from plastic packaging is intended to optimize the efficiency of packaging. Nevertheless, these materials prevent the recycling of packaging because they become contaminants to the recycling process. Food multilayered packaging containing poly (ethylene terephthalate) PET, poly (ethylene) PE and aluminum was used as filler in the preparation of composites with post-consumer high density polyethylene matrix. Composites containing up to 50 wt% of filler were feasible to prepare, allowing the obtention of a material with varied mechanical and thermal properties. This feature allows the preparation of composites suitable for specific application. The addition of multilayer matter in the polyethylene matrix provided a material with excellent mechanical properties such as higher tensile impact strength (148 J/m) and elasticity (350 MPa) as compared to pure polyethylene (40 J/m and 450 MPa).

Rapid Solidification Processing of metals and alloys is established by increasing the undercooling through application of high cooling rates (102-106 K/s) or by reducing nucleation sites using low cooling rates (1 K/s). Melt undercooling opens new solidification pathways for new non-equilibrium phases and unusual microstructures. Several techniques have been developed to reduce nucleation sites and produce increased undercooling in metals and alloys, including the fluxing technique. In this work, an Al96Fe2Nd2 alloy was solidified through fluxing technique and its microstructure and microhardness were investigated as a function of the undercooling level. An increase in the undercooling level from 30 K to 109 K promotes changes in morphology and on the microhardness of the Al96Fe2Nd2 alloy.

Background: Alzheimer’s disease is a progressive and neurodegenerative disorder characterized by deterioration of brain functions. Psychosocial interventions such as music and photographic stimuli may contribute to cognitive and sensory exercise or rehabilitation. Objective: Evaluate musical and photographic stimuli in elderly people with Alzheimer’s disease. Methods: It is an uncontrolled clinical trial, before-after type, eleven subjects composing the sample. Participants were submitted to Katz Index, Autobiographical Memory Test, GDS-15, Mini-Mental State Examination. The collection instruments were used on the first and last day of intervention, individually. There were 2 sessions in the week with duration of 50 minutes totaling 20 sessions. Data were analyzed by descriptive and inferential statistics and as variables expressed as mean standard deviation. Results: There was a significant effect of cognitive activity (P , it was observed that a small advance (P = 0.05) of the daily life activities. With the analysis of GDS-15, it is verified that they are more effective for the increase of the previous self-estimation of the therapy (P = 0.94). In the application of the AMT, it is observed that there was a better recruitment of the memory for the neutral words. Conclusion: Musical and photographic stimuli had a positive effect on the cognitive level, daily life activities and autobiographical memory in seniors with Alzheimer’s disease.

One of the most studied topics in cartography is the extraction of interest cartographic features. Using the image of the cartographic feature extracted, the researchers can provide the update of the cartographic maps, more easily, and study other topics like the area of the cartographic feature. For this reason many automatic routines were created with the intent to perform the extraction of the cartographic features of interest. However, some features can not be found by the algorithm, so the current article aims to show the results with a semiautomatic routine where the user can interact with the algorithm choosing some options and showing some features of the extraction"s goals to help the routine realize the necessary. The results found until now with this algorithm are enough to say that this can be used to realize the cartographic features extraction independent of where it will be used for.

Diamond-like Carbon (DLC) coatings have attracted significant attention due to their low friction coefficient, high degree of hardness, chemical inertness, and high wear resistance as well as and their many possible uses in metallurgical, aeronautical, and biomedical applications. However, DLC has low adhesion strength to metallic substrates. Carbonitriding was performed before DLC deposition to improve this adherence. Different concentration of nitrogen in the gas mixture was used during the carbonitriding of Ti6Al4V alloy. DLC films were subsequently grown from methane using plasma enhanced chemical vapor deposition. The samples were characterized with Raman scattering spectroscopy, nanoindentation, and tribological tests. Films from 80.0% N2 had the best friction coefficient (0.07) and a critical load of ~22 N. In the scratching test, these films had adhesive failure and they completely detached from the substrate only in the end of the tests. SEM images show carbonitring promoted a significant increase in the surface defects (homogeneously distributed) but without the presence of microcracks. EDX analysis indicated that nitrogen element was diffused throughout the thickness of the samples. Hydrogen and carbon atoms from carbonitriding formed a diffusion-barrier layer that can be used as the first step for DLC deposition. This carbonitriding can also provide a carbide layer, which serves as the precursor for the nucleation and growth of DLC films.
