Estudo para determinação de uma metodologia para o ensaio de arrancamento que avalia aderência aço/concreto

This work talks about the importance of the steel adhesion to concrete, reinforced concrete structures, their testing and forms of measurement used and how the results are used in the structural design, which uses as a reference the NBR 6118 and NBR 7480. It also deals with the importance of a reliable assessment, discussing failures that the test used, NBR 7477, features in specific circumstances, as discussed under the EC-094. It also presents an initial proposal for simplified pullout test, which aims to analyze the grip on steel bars with diameter less than 10 mm, which results when used standardized testing by ABNT NBT 7477, has shown excessive variability, the main criticism of the trial today used without distinction to be established thick or thin bars. The proposal also presented methodology is in the consolidation phase, given the time and the volume of necessary tests. For this reason it is not possible to make a comparison between the values obtained and the results of the test used on the basis of the standard in force, this can only be done once the front with a continuation of this work

Analysis of the NMDA in Focal Cerebral Ischemia in Rats

NMDAR (N-methyl-D-aspartate receptor) is one subtype of ionotrophic glutamate receptor which is extensively distributed in the central nervous system (CNS). In the mammalian CNS, NMDAR serves prominent roles in the pathophysiologic process of cerebral ischemia. This study aimed to investigate the pattern of expression of protein and gene of the excitatory neurotransmitter NMDAR in experimental focal cerebral ischemia and the hole of neuroprotection with hypothermia and ketoprofen. 120 rats were randomly divided into 6 groups (20 animals each): control - no surgery; sham - simulation of surgery; ischemic - focal ischemia for 1 hour, without reperfusion; ischemic + intraischemic hypothermia; ischemic + previous intravenous ketoprofen, and ischemic + hypothermia and ketoprofen. Ten animals from each experimental group were used to establish the volume of infarct. Transient focal cerebral ischemia was obtained in rats by occlusion of the middle cerebral artery with an intraluminal suture. The infarct volume was measured using morphometric analysis of infarct areas defined by triphenyl tetrazolium chloride and the patterns of expression of the protein and gene NMDA were evaluated by immunohistochemistry and quantitative real-time PCR, respectively. Increases in the protein and gene NMDA receptor in the ischemics areas were observed and these increases were reduced by hypothermia and ketoprofen. The increase in the NMDA receptor protein and gene expression observed in the ischemic animals was reduced by neuroprotection (hypothermia and ketoprofen). The NMDA receptor increases in the ischemic area suggests that the NMDA mediated neuroexcitotoxicity plays an important role in cell death and that the neuroprotective effect of both, hypothermia and ketoprofen is directly involved with the NMDA.
