Plant-derived substances such as curcumin and trans-resveratrol, both of which have anti-inflammatory properties, may have a beneficial effect on human skin. The present study analyzed the effects of topical formulations containing curcumin or trans-resveratrol on the recovery and rejuvenation of skin after chemical peeling. The study was performed on rats, randomly divided into seven groups of six animals each. Superficial peeling was performed using a 50% glycolic acid gel, which was applied to the dorsal region of each animal. Rats were then treated with the experimental formulations for 15 days. On the sixteenth day, skin samples were taken and mounted on slides for histological analysis. Statistical analysis showed that the formulation containing trans-resveratrol led to increased dermal and epidermal thickness, while the formulation containing curcumin had no effects on epidermal thickness. The increased epidermal thickness may reflect greater skin vitality, although this was not directly evaluated. The increase in dermal thickness may be attributed to greater collagen production, which may increase skin firmness and elasticity, and lead to skin rejuvenation as well as wrinkle reduction. Formulations containing curcumin or trans-resveratrol may have potential for the topical treatment after peeling and of sensitive skin, in addition to being used for their antiaging properties.

With the increasing development of Brazil in recent years, major engineering construction works have been designed and built, partieutarly those involving large volumes of mass concrete, such as in the case of dams. Mass concrete, due to its large size and volume, presents a considerable temperature rise caused by cement grain hydration. This temperature rise can be sufficient to cause concrete crack and/or cracking, which may lead to serious problems. In this paper, we sought to study heat generation and temperature field in mass concrete through ANSYS software, which uses finite element method to analyze the problem. This program allows temperatures to be checked for different concrete ages. With that, it is possible to evaluate the temperatures obtained and the factors influencing the results in a short period of time at a low cost. With the help of the software, it is possible to check the temperatures for different concrete properties by analyzing them on different concreting days. Therefore, it was possible to establish that the properties of the concrete directly influence the temperature evolution phenomenon.

Abiotic parameters and phytoplankton were collected during 2010 and 2011 with the purpose of describing the phytoplankton distribution and the environmental characteristics. The diatoms were the most representative group in terms of species richness;in terms of density, the Cyanobacteria were more representative. Diversity and equitability were generally low in the estuary due to the dominance of Microcystis aeruginosa, an opportunistic and potentially toxic species of Cyanobacteria. The estuarine region is strongly impacted by high pollutant loads, especially nitrogen and phosphate compounds. Historical series of Apparent Oxygen Utilization (AOU) showed negative trends associated with changes in the estuarine system. The main biological components changed through 1999-2011 period. The dominance of the species changed from the Bacillariophyta in previous studies to the Cyanobacteria in our study. The species Microcystis aeruginosa, through its high density, dominance and frequency of occurrence, was the key species in the area.

This study aimed to elaborate on theoretical model of the perceptions, feelings, and meanings of early stress for people with depression. To perform a qualitative study based on the Symbolic Interactionism and Grounded Theory, we interviewed 12 patients diagnosed with depression. It was structured a model based on “walking between traumatic childhood and the adult life with depression,” integrating eight inter-articulated categories that represent the perceptions, feelings, and meanings of the experiences of the depressed individual with a history of early stress. The theoretical model constructed meanings and conditions that affect the individual from a traumatic childhood to depression in adulthood.

The identifying of the preferred breeding sites of sand fly immature forms is quite important to the understanding of the vector’s biology and the development of more effective control strategies for leishmaniasis. In the present study, it was analyzed experimentally;the potential of dog feces of serving as breeding substrate to Lutzomyia longipalpis. Two situations were tested: 1) the life cycle of the insects from larvae to adults, 2) the whole cycle from adults to adults. Our results demonstrated for the first time that: 1) L. longipalpis can be easily bred in dog feces, suggesting that it could represent a potential raising substrate to immature forms for this species;2) L. longipalpis larvae are able to make galleries on a substrate, literally burying themselves in this to function also as a shelter;3) from the previous information that dogs infected with Ancylostoma caninum can present dodecanoic acid in their feces, we suggested that this substrate may be particularly more attractive to L. longipalpis females seen that this molecule is the same component of their oviposition pheromone, which is produced by the accessory glands and secreted onto the eggs;4) after the copulation the males may landing on the substrate and continued beating the wings intermittently until the death in a similar behavior also noticed in other situations associated to kairomones response or pheromone production. Therefore, we suggested that it is very likely that dog excrements could serve as an important breeding substrate for L. longipalpis in endemic areas of visceral leishmaniasis in the New World.

Currently, engineering processes require reduced manufacturing time and low cost, in addition to the growing demand for workpieces with high accuracy. Workpieces with complex geometries and free forms has been a common practice in industries from different sectors such as： automotive, aeronautics, bioengineering among others. One way to satisfy the market requirements satisfactorily is making measurements more efficient to make the production process faster, in other words, it is necessary to make the inspection system more accurate and flexible. The coordinate measuring evolved over the past three decades and today it is the technology that best meets the requirements of modem manufacturing through CMMs （coordinate measurement machines）. The CMMs are important tool for design, fabrication and inspection of manufactured products, also used in the application of reverse engineering. These machines are also used by engineers in order to produce an accurate digital model in a virtual space for later use in CAD （computer-aided design）/CAM （computer-aided manufacturing）. It is worth mentioning that the accuracy of the modeling process of given piece depends on the number of control points that are captured on the workpiece surface. Consequently, the laser inspection systems are the best tools for use in reverse engineering, but more expensive when compared to contact measurement systems that use the TTP （touch trigger probe）, also used by CMMs. In this case, this paper aims to present an approach based on NURBS （non-uniform rational B-splines） to obtain free form curves and surfaces from a group of points obtained by using a contact sensor, the touch trigger probe. NURBS is an important mathematical tool and consists of generalizations of Bezier curves and surfaces and B-splines. The approach proposed in this paper can be applied for obtaining free form curves and surfaces in spur and helical gears. Experimental results obtained by measuring spur gears showed that the NU
