In this work it is assessed the performance of Portland cement-based mortar to the grouting of type II ceramic plates with the addition of unusable tire rubber powder. It is presented a bibliographical review about the subject in which is done the theoretical and methodological foundation of the whole investigative process. The analyzed universe comprises a sample of mortar to the grouting of conventional ceramic plates type II (reference sample) and five more samples to the grouting of ceramic plates type II, which were made up of the addition of unusable tire rubber powder in the respective proportion (in mass) of 4%, 8%, 12%, 16% and 20%. These mortar samples were subject to the trials of determination of the consistency index (Brazilian Standard NBR 13276:2005), water retention ( Brazilian Standard NBR 14992 Attachment B:2003), permeability in 240 minutes (Brazilian Standard NBR 14992 Attachment G:2003), absorption of water by immersion (Brazilian Standard NBR 9781:2013), resistance to compression (Brazilian Standard NBR14992 Attachment D: 2003), resistance to traction in the flexion (Brazilian Standard NBR 13279:2005), resistance of traction adherence (Brazilian Standard NBR 14081 part 4:2012) and hardened mass density (Brazilian Standard NBR 13280: 2005). It has been found out from the analyzes of the results in the trial the following situation: the reference mortar used met the established requirements in the norms of specifications corresponding to only six from the eight parameters assessed in the research; the mortar with addition of 4,0% of tire rubber powder met the established requirements corresponding to only the resistance to compression and the resistance of adherence to traction. Thus, the other kinds of mortar with addition of 8,0 %, 12,0 %, 16,0 % and 20,0 % of tire rubber powder met the requirements of specifications corresponding to only the resistance to compression and the resistance of adherence to traction. This result concludes that the adding of tire rubber powder does not grant improvement to the mortar of type II grouting to the laying of ceramic plates.

There is a bidirectional association between periodontal disease (PD) and diabetes mellitus, in which diabetes favors the development of PD and PD, if left untreated, can worsen the metabolic control of diabetes. Thus, periodontal disease should be treated to restore periodontal health and reduce the complications of diabetes. Therefore, the objective is assess the effect of full mouth periodontal therapy decontamination (Full Mouth Desinfection - FMD) in diabetic type II patients with chronic periodontitis during 12 months. Thirty-one patients in group one (G1) and 12 in group two (G2) were followed at baseline, 03, 06 09 and 12 months. There following clinical parameters were accessed: probing on bleeding (BOP), visible plaque index (PI), probing depth (PD), clinical attachment level (CAL) and gingival recession (GR). For diabetic patients, there were also made laboratory tests to evaluate blood parameters: fasting glucose and glycated hemoglobin. The results had been analyzed in two ways: all sites in the mouth and another with diseased sites. The Mann-Whitney, Friedman and Wilcoxon tests were used with 5% significance. Intergroup analysis of all sites it is clear that there was no significant difference over time concerning PD, BOP, PI, CAL and RG. However, when evaluating the diseased sites, we observed significant difference for CAL and PD, with higher values in G1. The intragroup analysis for all sites showed a statistically significant reduction at PD, PI and BOP in both groups. Intragroup analysis of periodontal affected sites showed a statistically significant reduction in PD, BOP and CAL in both groups. There was also a statistically significant increase in RG values. There was no significant change concerning glycated hemoglobin and fasting glucose in the G1. Therefore, it can be concluded that there were improvements in periodontal parameters over the 12 months of research, but without changes in glycemic levels of diabetic patients. Thus, periodontal therapy proved effective in maintaining oral health.

A diabetes mellitus do tipo 1 (DM1) é o distúrbio endócrino-metabólico mais frequente em crianças. É uma doença autoimune resultado da destruição selectiva das células beta pancreáticas. A velocidade de destruição das células beta pode ser rápida em algumas pessoas e lenta em outras; esta última é típica de adulto é conhecido como diabetes autoimune latente em adulto (LADA). A sua etiologia envolve factores ambientais e genéticos, dos genes envolvidos a maior contribuição vem da região do genoma onde estão localizados os genes do Complexo Principal de Histocompatibilidade (MHC). A combinação de diferentes alelos do sistema de antigénio leucocitário humano tipo II (HLAII) esta associada a susceptibilidade da doença e as principais molécula envolvidas são a DQ e DR. O estágio pré-clínico da doença se caracteriza pela presença de auto-anticorpos, sendo o anti-GAD o mais sensível nesta patologia. OBJECTIVO: Analizar a frequência dos polimorfismos HLA-DR/DQ em angolanos portadores de diabetes tipo 1, residentes em Luanda. O tipo de estudo adotado foi casocontrolo num universo de voluntários provenientes da consulta externa de hospitais e clínicas locais no período de outubro de 2012 a outubro 2013. A amostra biológica utilizada foi sangue total, tendo sido processada no laboratório LABGENE, da Faculdade de Medicina (FM) da Universidade Agostinho Neto (UNA). Os auto-anticorpos, anti-GAD, foram doseados pelo método de ELISA. O ADN genómico foi extraído à partir de sangue total periférico e tipagem genética foi realizada mediante PCR-SSP.O alelo DQB1*02 (DQ2/DQ2) (p=0,033, OR= 4, IC (1,2-13,3) foi associado a susceptibilidade da DM1; os alelos DQB1*06 (DQ6/DQ6) (p=0,000, OR=0,30, IC (0,17-0,54); *11 (p=0,011, OR=0,14, IC=0,032-0,62); *13 (p=0,006, OR=0,13, IC=0,049-0,588) e *15 (p=0,001, OR=0,044, IC=0,005-0,39) foram associados a proteção. Foi encontrado 29,2% de positividade para o anti-GAD, não houve associação significativa (p=0,69) entre a resposta positiva do anti-GAD e a idade. Não foi encontrada associação significativa (p=0,39) entre o tempo de diagnóstico e resposta humoral. Observou-se associação significativa entre os alelos de risco DQB1*02 (p=0.000) e resposta positiva para anti-GAD; da mesma maneira houve uma associação significativa para os alelos DQB1*06 (p=0,002), DRB1*11 (p=0,048); *13 (p=0,004) e *15 (p=0,021) e a resposta negativa do anti-GAD.Os dados demostram o forte envolvimentos do gene HLA-II (DQ) com a suceptibilidade a DM1 e sugere que a autoimunidade se desenvolve na presença de susceptibilidade genética, quer dizer, em associação com alelos HLA-II específicos.

The green corn demand, production of quality bean grain and better use of land and water resources can be used by small farmers through the intercropping of common bean and green corn in off-season crops. Field experiments were conducted in the Polo Regional Extremo Oeste-APTA, in Andradina -São Paulo State, in 2005 and 2006. The objective was to evaluate the performance of green corn cultivars grown in single crop and intercropped with common bean. The randomized blocks design with 8 treatments constituted by the combination of two corn (CATIVERDE 02 and XB 7012) and three common bean cultivars of different growth habits: IPR Colibri (I), IPR Juriti (II) and IAC Carioca (III), with four repetitions was used. The influence of the intercropping on the performance of corn was not significant. The hybrid XB 7012 was more productive in intercropping and in single crop. The hybrid production more 8000 commercials ears and lengt ears when compared with the variety. The intercropping with the IPR Juriti or IPR Colibri cultivars were the most profitable for the producer.

O objetivo deste experimento foi avaliar o efeito de diferentes populações de plantas e espaçamentos entre linhas de cultivo na produção de massa seca, rendimento de grãos e componentes do rendimento da cultura do feijoeiro irrigado. O experimento foi conduzido no ano agrícola 1997/1998, em área do Departamento de Engenharia Rural da Universidade Federal de Santa Maria (UFSM), RS. A cultivar de feijão preto BR-FEPAGRO 44 - Guapo brilhante, habito de crescimento indeterminado (tipo II), foi submetida a três populações de plantas (175, 250 e 325 mil plantas há-1) e três espaçamentos entre linhas de cultivo (35, 50 e 65cm). Utilizou-se o delineamento experimental inteiramente casualizado, bifatorial, com quatro repetições. Irrigações por aspersão foram aplicadas quando a evapotranspiração máxima da cultura, estimada a partir da evaporação do tanque classe A, indicava um valor acumulado de 25mm. Os resultados demonstraram que as diferentes populações de plantas e espaçamentos entre linhas de cultivo não ocasionaram alterações no rendimento de grãos e massa de mil sementes. No entanto, o número de sementes por vagem e de vagens por planta aumentaram com a redução na população de plantas. Na fase do enchimento de grãos, a redução do espaçamento entre linhas de cultivo aumentou a massa seca da parte aérea das plantas. A cultivar de feijoeiro, BR-FEPAGRO 44 - Guapo brilhante, apresenta elevada plasticidade dos componentes do rendimento, havendo compensação no rendimento de grãos nas menores populações de plantas com aumento da produção por planta.
