Fernandes, Igor Lima;Santana, Larice Oliveira;Silva Júnior, José Batista Da;Motta, Marcel Machado Da;Moura, Alex Rodrigues;Prudente, Ana Carolina Lisb?a;Torres Neto, Juvenal Da Rocha;
Journal of Coloproctology (Rio de Janeiro) , 2011, DOI: 10.1590/S2237-93632011000300009
Abstract: anus neoplasm accounts for 2 to 4% of colorectal tumors, being more prevalent around the seventh and the eighth decades. females are mostly affected, and the ratio is 3:1. its increased prevalence amongst the population in the past years is probably related to the higher number of people that are affected by sexually transmitted diseases, mainly human papillomavirus (types 16 and 18, mostly) and/or the human immunodeficiency virus. diagnosis is based on clinical findings and anatomopathological tests. the treatment of choice is radiochemotherapy, and the rescue surgery with abdominoperineal resection is used for recurrence and persistence cases. a retrospective and prospective longitudinal observational study was performed with 11 patients diagnosed with anal neoplasm from 2004 to 2010. six (54.5%) were females and five (45.5%) were males. the incidence was higher in the sixth decade, at the mean age of 54.45 years. the most frequent histological type observed was the epidermoid carcinoma, and the most frequent cell differentiation type was the moderately differentiated. chemotharapy associated with radiotherapy was used in 81.9% of the patients, and abdominoperineal resection was necessary as a rescue surgery in 18.2% of the patients.

Abstract: the experiment was performed to evaluate the productive response of a degraded b. humidicola pasture to different pasture recovery methods. it was used a split-plot within a confounded randomized block design. the main plot was represented by the combination among managements and fertilization levels and the sub-plot by the deferred periods. the experimental treatments were four recovery managements (no-tillage, harrowing, harrowing + corn as a companion crop, no-tillage + corn as a companion crop), two levels of nitrogen (0 and 100 kg/ha of n), two levels of phosphorus (0 and 100 kg/ha of p2o5) and, different periods of deferment (113, 156, 200 and 240 days), totalizing 64 treatments with three replications each one. it was found a significant interaction between recovery managements and p fertilization. the average dry matter accumulation (dma) was 7.52; 1.68; 1.10 and 4.43 t/ha of b. humidicola for no-tillage, harrowing, harrowing + corn as a companion crop, no-tillage + corn as a companion crop, respectively. the highest deferment period increased dma, plant heigth and b. humidicola participation in the botanical composition, as well reducing percentage of other species in the dma and percentage of uncovered soil. brachiaria humidicola pastures at the initial degradation stage, grown in low available phosphorus soils, may be recovered using a deferment period associated to a phosphorus fertilization.

Abstract: the maintenance of the normal metabolism of minerals in the bone is a result of several factors including the mechanical demands that are applied to the bones by muscle contractions and gravity force. the proposal of this investigation was to study a model of tail suspension of rats thus simulating the skeletal alterations that may occur in a microgravity environment. the model was analyzed in terms of animal tolerance and the ensuing effects on the mechanical resistance of the tibiofibular complex. after a three-point bending test in flexion the main mechanical parameters were obtained, (load and deflection at the ultimate limit, load and deflection at the yielding point, stiffness and resilience). 53 adult female rats were used and distributed in four groups according to the length of time in suspension (control, 7, 14 and 21 days). the model of suspension was efficient with good animals adaptation and it caused a significant weakness of bones mainly in the 21-day period.
Cluster Analysis for Political Scientists  [PDF]
Dalson Britto Figueiredo Filho, Enivaldo Carvalho da Rocha, José Alexandre da Silva Júnior, Ranulfo Paranhos, Mariana Batista da Silva, Bárbara Sofia Félix Duarte
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.515232
Abstract:


This paper provides an intuitive introduction to cluster analysis. Our targeting audience are both scholars and students in Political Science. Methodologically, we use basic simulation to illustrate the underlying logic of cluster analysis and we replicate data from Coppedge, Alvarez and Maldonado (2008) [1] to classify political regimes according to Dahl’s (1971) [2] polyarchy dimensions: contestation and inclusiveness. With this paper, we hope to help novice scholars to understand and employ cluster analysis in Political Science empirical research.

Acta Ortopédica Brasileira , 2003,
Abstract: Os autores estudaram a influência da nutri o protéica na consolida o de fraturas em 40 ratos Lewis divididos em 4 grupos de 10. Durante 6 semanas os grupos 1, 2 e 3 receberam respectivamente dietas com 0, 19% e 36% de proteínas. O grupo 4 recebeu dieta sem proteínas durante as 2 primeiras semanas e com 36% de proteínas nas 4 semanas seguintes. Foram realizadas fraturas nas tíbias esquerdas ao final de 2 semanas e após 4 semanas das fraturas os animais foram sacrificados para estudo dos calos ósseos. Para a avalia o dos resultados foram utilizadas medidas clínicas, bioquímicas, radiográficas, densitométricas, e histomorfométricas. Concluiu-se que a dieta hiperprotéica alterou a consolida o óssea produzindo um calo maior e mais resistente, mas n o alterou a qualidade em concentra o de cálcio e em porcentagem a quantidade de tecido ósseo.
