Multidimensional effects through porous building elements is barely explored in the literature due to many difficulties such as modeling complexity, computer run time, numerical convergence and highly moisture-dependent properties. Furthermore, when the multidimensional effect is considered, thermal bridges may play an important role on the hygrothermal building performance due to local increase of heat and mass flux densities. Therefore, in order to analyze the effects of building lower and upper corners, a multidimensional model has been developed to calculate the coupled heat, air and moisture transfer through building envelopes. For improving the discretized model numerical stability, the algebraic equations are simultaneously solved for the three driving potentials: temperature, vapor pressure and gas pressure gradients. In the results section, the coupling of the upper corner, wall, lower corner, ground and floor are analyzed for different boundary conditions in terms of temperature and relative humidity profiles, vapor flow and heat flux, showing the importance of a detailed hygrothermal analysis for accurately predicting building energy consumption, thermal comfort and mould growth risk.

Araucaria angustifolia decreases its growth ratio during the fall and winter in response to adverse environmental conditions such as in temperate fruits where bud dormancy as a survival startegy. The aim of this study was to evaluate the dynamics of the respiratory activity of apical meristems of plagiotropic branches of Araucaria angustifolia. To determine the respiratory activity, samples with 0.4 g of apical buds of plagiotropic branches of young and adult plants were collected. These buds were maintained during two hours in 5 mL of 2,3,5-triphenyl tetrazolium chloride (1.2%) in a growth room at 25 °C. Then, it was maintained during one hour in 4 mL of absolute ethyl alcohol and then the absorbance was determined by reading in spectrophotometer at 560 nm. The respiratory activity of apical meristems of plagiotropic branches of Araucaria angustifolia changed during the year, reducing in mid-spring and become lower in the winter in both young and adult plants. Adult plants remained with lower respiratory activity for a longer period, until the beginning of summer. © 2016, Universidade Federal de Santa Maria. All rights reserved.

Objective: To evaluate the effects of low-level helium-neon (HeNe) laser on cutaneous wound healing in rats. Methods: Sixty Wistar rats were divided into control group and experimental group. A sutured longitudinal, dorsal-medial incision was made, with simple separate stitches. The experimental group was irradiated daily in three areas of the wound with HeNe laser (5mW maximum continuous power, 632.8 nm wavelength, 4 J/cm2 energy density and 0.015 cm2 laser beam area) for 36 seconds. The areas were evaluated on the third, seventh and fourteenth days postoperative. Histological sections were stained with hematoxylin-eosin to determine the type of inflammatory reaction according to the protocol by Vizzotto et al. (2003)* and with Picrosirius to identify types I and III collagen and the collagen maturation index (CMI). Immunohistochemical detection was employed with anti-CD45-LCA to recognize the inflammatory cells. Results: Both groups had the same inflammatory pattern. The experimental group had fewer inflammatory cells at the three evaluation times (p<0.001) with faster reduction in the number of leukocytes. The experimental group had greater total collagen density on the third day (p=0.001), with more type III collagen (p=0.001) and more type I collagen (p=0.001). There was no significant difference in the CMI. Conclusion: Low-level laser irradiation does not change the quality of the inflammatory response, but it does reduce its intensity; it increases collagen deposition in the early stages of the healing process and does not interfere with collagen maturation. © Revista Brasileira de Fisioterapia.

Objective To study the anatomy of the hamstring tendons insertion and anatomical relationships. Methods Were selected ten cadaver knees with medial and anterior intact structures. The dissection was performed from anteromedial access to exposure of the inserction of the flexor tendons (FT), tibial plateau (TP) and tibial tuberosity (TT). A needle of 40 × 12 and a caliper were used to measure the distance of the tibial plateau of the knee flexor tendons inserction at 15 mm from the medial border of the pattelar tendon and tibial tuberosity to the inserction of the flexor tendons of the knee. The angle between tibial plateau and the inserction of the flexor tendons of the knee (A-TP-FT) was calculed using Image Pro Plus software. Results The mean distance TP-FT was 41 ± 4.6 mm. The distance between the TT-FT was 6.88 ± 1 mm. The (A-TP-FT) was 20.3 ± 4.9 degrees. Conclusion In the anterior tibial flexor tendons are about 40 mm from the plateau with an average of 20 degrees. © 2013 Sociedade Brasileira de Ortopedia e Traumatologia.

In vendor-managed inventory systems, logistics decisions are centralized at the vendor, allowing inventory storage and transportation costs to be reduced simultaneously. The operation of such systems requires the solution of a complex combinatorial optimization problem, known as Inventory Routing Problem (IRP), which involves managing client inventory and determining the frequency and size of product deliveries as well as the route taken by the vehicle over a given planning horizon. We present three new dynamic formulations for an economic order quantity distribution policy for the multivehicle inventory routing problem (MIRP). A mixed-integer linear programming (MILP) model with additional practical constraints was used for the MIRP, considering a three-echelon logistic system. A new heuristic approach that breaks the MIRP down into the following two sub-problems was also proposed: the first sub-problem deals with the scheduling of deliveries and the formation of delivery clusters over the planning horizon; the second sub-problem builds the routes for the delivery clusters using classic route construction heuristics and a procedure for intra-route improvements. Adjustments between routes are performed with the aid of a new large neighborhood search (LNS) strategy. Small, medium, and large scenarios with different storage and transportation costs were generated using parameters based on data from the literature. Extensive computational tests were carried out to determine the effectiveness of the proposed distribution policy and the heuristic used.
