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: mixed pastures of brachiaria decumbens with stylosanthes guianensis cv. mineir?o and b. brizantha cv. marandu with s. guianensis cv. mineir?o, under three stocking rates (0.8, 1.2 and 1.6 au/ha) were evaluated in regard to the animal daily gain and liveweight gain per ha, in the brazilian savanna, in order to suggest the most adequate management. a randomized block in a split-plot design with two replicates was used. the plots treatments were constituted of a 2x3 factorial, two grasses (brachiaria decumbens and b. brizantha cv. marandu) associated with stylosanthes guianensis cv. mineir?o and three stocking rates (0.8, 1.2 and 1.6 au/ha), and the split-plot as year seasons. weaned nellore steers (average initial weight of 138 kg), in the beginning of the experiment, were used. the grass, season and stocking rate affected the daily average weight gain. animals grazing b. decumbens showed higher dwg than those grazing b. brizantha (409 x 333 g/head.day). it was observed higher dwg in the rainy season in relation to the dry season (490 and 194 g/head.day). dwg decreased linearly as stocking rate increased, and values of 435, 371 and 308 g/head.day were estimated for stocking rates of 0.8, 1.2 and 1.6 au/ha, respectively. animals grazing b. decumbens showed higher production per ha than those grazing b. brizantha, with liveweight gains of 464 and 352 kg/ha.year, respectively. weight gain per ha was affected by grass and year season. the production per ha was higher in the rainy season than in the dry one, with average values of 331 and 77 kg/ha.year, respectively. the stocking rate did not affect production per ha, however, there was curvilinear tendency, indicating that the most adequate stocking rate ranged from 1.25 to 1.30 ua/ha.
The Effect of UV Light and CO2 in the Production of Polyunsaturated Aldehydes in Skeletonema costatum (Bacillariophycea)  [PDF]
Luiz Felipe C. da Motta Pacheco, Eduardo Uribe, Jorge Pino, José Troncoso, Andrés Quiróz
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.524379
Abstract:
Skeletonema costatum was submitted to two experiments using UV lights and CO2with the purpose of observing changes in the lipids profile and the synthesis of polyunsaturated aldehydes (PUA) after cell disruption. When cells receive CO2 supply, it was noticed that the production of PUA was significantly lower. The same was observed when the culture was treated with a dose of 45.9 kJ·m-2 of ultra-violet A/B ray. The premise to all experiments was the production of 2,4-heptadienal compared to the supply of EPA as substrate. As a result, the same synthesis rate was observed both when the CO2 treatment was applied and in the experiment control. On the other hand, the culture subjected to ultraviolet radiation showed a 68% greater demand with the utilization of the substrate. These observations suggested that EPA was consumed before cell disruption and was probably exuded to the surrounding environment as a sign of stress. Changes in cell morphology could be observed by the migration of the chloroplast nearby the cell wall, where PUA was produced, indicating a defense strategy.

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.

Abstract: forty singletons crossbred texel lambs were assigned to four treatments to compare their performance in either feedlot or at pasture, with or without supplementation. in the first treatment ("min"), the lambs received a mineral supplementation and stayed with their mothers up to 105 days old in a paddock of panicum maximum cv. coloni?o but only the lambs had access to the supplement. the second treatment ("prot") differed from the fist one only in that the lambs were supplemented with protein salt rather than mineral salt. in both third ("creep") and fourth ("feedlot") treatments the lambs had access to creep feeding but at 60 days of age animals from the fourth treatment were weaned and finished in feedlot until they reached 105 days of age. comparisons among treatments were done by contrasts and f-test. males gained more weight than the females counterparts from 21 days old until completion of the trial. lambs on creep and feedlot treatments had better performance than those on min and prot supplementation. at 105 days of age, the average weights of the males were: 36.98 kg (feedlot), 34.16 (creep), 32.14 kg (prot), and 30.24 kg (min). lambs on creep and feedlot treatments reached their finish weight (from 28 to 32 kg) at 84 days of age. no significant difference on performance was observed between "min" and "prot" treatments in the current study. it can be concluded that production of lambs at pasture was not compromised under the conditions of this trial.

Abstract: the plating process generates solid waste rich in heavy metals and aiming to reduce environmental impact of such waste, this work suggests a methodology for zinc reduction, through a 24 factorial planning, studying the influence of the following variables: acid concentration (15, 20 or 30% v/v), acid type (sulfuric or hydrochloric), acid volume (15, 20 or 25 ml) and extraction time (12, 24 or 36 h). through this methodology it is possible to establish the optimal conditions (15 ml of a 30% hydrochloric acid concentration during 12 h) to get a 100% efficiency in zinc extraction.

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.

Abstract: the effect of ultrafiltration and precipitation by tca on the peptide profile of casein hydrolysates was studied. after these treatments, the hydrolysates were fractionated by size-exclusion hplc and the rapid correct fraction area method was used for quantifying the peptides. these treatments changed the peptide profile having reduced the di- and tripeptide content of some enzymatic preparations. in order to explain these results, some considerations concerning operational conditions and peptide hydrophobicity were made.

Abstract: duplex stainless steels (dss) are characterized by the presentation of an interesting combination of good mechanical properties and corrosion resistance, having a wide application in chemical and petrochemical industry. generally, the manufacture and repair of any industrial equipment involve welding operations, even though it is very important to evaluate the influence of welding parameters. it is very important to obtain appropriate ferrite content in the weld metal, so that the variation of heat input can influence on the ferrite content directly. therefore, the aim this work is to evaluate the influence of the heat input on the microstructure and the microhardness of the weld metal of the dss. the weld overlay were performed with deposition of two layers on the structural steel astm a516 gr.60, using as filler metal the aws e2209-17 coated electrode. three energy levels (15, 20 and 24 kj/ cm) were used, varying the welding current and speed. it was verified that for energy levels used didn't have significant difference on the ferrite content, but the first bead deposited had a higher austenite content in relation to other beads. all conditions got microhardness below the critical value.
