The importance of the role played by the so-called stress concentration factors (or symbolically referred to as Kts) in analysis and design in both mechanical and structural engineering is a well-established fact, and accuracy and ease in their estimation result in significant aspects related to engineering costs, and additionally on both the reliability in the design of parts and/or in the analysis of failed members. In this work, rectangular finite width plates of both isotropic and orthotropic materials with circular and elliptical holes are considered. Based on two key observations reported herein, it is shown in a partially heuristic engineering sense, that Howland's solution curve for the stress concentration factors for finite width plates with circular holes subjected to tension can be viewed as a master curve; accordingly, it can be used as a basis to rather accurately estimate stress concentration factors for isotropic finite width tension rectangular plates with centered elliptical holes and also rather accurately used to estimate stress concentration factors for orthotropic finite width rectangular plates under tension with centered elliptical holes. Two novel concepts are defined and presented to this effect: geometric scaling and material scaling. In all the examined and reported cases, the specific numerical results can be obtained accurately using a hand-held calculator making virtually unnecessary the need to program and/or use other complex programs based on the finite element method, just as an example. The maximum recorded average error for all the considered cases being 2.62% as shown herein. © Institution of Mechanical Engineers.

Background Recently, lesbian, gay, bisexual, and transgender (LGBT) scientific production is growing, but transgender (TG) people is less considered in the LGBT-related research, highlighting the lack of representative data on this neglected population. Methods: To assess the current status of scientific production on TG population, a bibliometric study was performed using the articles on TG people deposited in five databases, including PubMed/Medline, Scopus, Science Citation Index (SCI), Scientific Electronic Library Online (SciELO) and Latin American and Caribbean Health Sciences Literature (LILACS). Results: The PubMed/Medline search retrieved 2370 documents, which represented 0.008% of all articles recorded in Medline. The Scopus search identified 4974 articles. At SCI, 2863 articles were identified. A search of the SciELO database identified 39 articles, whereas the LILACS search identified 44 articles. Most papers were from the US (57.59%), followed by Canada (5.15%), the UK (4.42%), Australia (3.19%), The Netherlands (2.46%) and Peru (1.83%). These six countries accounted for 74.6% of all scientific output. Conclusions: The findings indicate that the TG-related research is low, especially in low-income developing countries, where stigma and discrimination are common. More awareness, knowledge, and sensitivity in healthcare communities are needed to eliminate barriers in health attention and research in this population. © CSIRO 2017.

Objective: To determine the factors of capacity related to the use of appropriate prenatal control in pregnant women in Sincelejo, Colombia in 2014. Methodology: A crosssectional analytical study was carried out with a sample of 730 pregnant women, chosen by conglomerate sampling. Information was collected by means of a social-demographic and family characterization survey, Apgar Family and Services Satisfaction Scales with sanitary services. Microsoft Excel V2010, SPSS V 17 were used for data tabulation and OR tests and Multivariated Analysis for the analysis. Results: 97.7 % of the pregnant women attend to prenatal control. Regarding reasons to attend prenatal control, 83,9 % (598) said they went to detect alterations and 14,6 % (104) following somenone else´s recommendations. 17 women did not attend to control and cited as reasons: too much paper work 47,1%(8), have missed the appointment 23,5 % (4), believe not needing control because they had delivered babies with no problem 23,5 %(4) and believe it is too early to start control (5,9 % (1). About the use of prenatal control, it was found that 75,6 %(552) uses appropriately this service. Conclusions: When doing a statistical analysis by odds ratios (OR), to find association with the factors of capacity, we found a statistically significant association between the adequate use of prenatal control and two variables of ability: affiliation to a health regime and satisfaction with prenatal control services. © 2016, Universidad del Norte.

The objective of this work was to evaluate the effect of organic and chemical fertilization applied during the dry and rainy season on the population density (CFU/g) and distribution of soil bacteria in the agroecosystem of Bothriochloa pertusa in the sabanas of Sucre. For the in-situ evaluation of fertilizers a plot of 2280 m2 was selected, defining an area of 1848 m2; using a completely randomized block with measures repeated for the climatic seasons. The treatments were: TEST control, ABM mineral fertilizer -urea, COMP chicken manure compost, COMB cattle manure compost and LOMB Vermicompost. In the chemical fertilizers was applied 218 kg/ha of urea (46%), and in the organic, 1.5 tonnes/ha of organic fertilizer. To determine the effect of fertilizers on the population density of bacteria in the treatments, were used analysis of variance not parametric, and on the distribution, analysis statistical descriptive. The data were analyzed in the statistical program R During the dry season, the soil with mineral fertilizer treatment, showed better distribution of gram-negative bacteria, and with Vermicompost, of Pseudomonadaceae; In rains, the treatment lombricompost presented major density of Gram-negative bacteria, better distribution of these and of positive Gram, and the treatment chicken manure compost, better distribution of Pseudomonadaceae and Cocobacilos Gram-negative. It is concluded that only in the soil treatment vermicompost during the rainy season, was affected the density of gram-negative bacteria, and the distribution of bacterial groups varied in each season, according to the group and treatment. © 2017, Fundacion CIPAV.

The effect of radial heat transfer in a structured catalytic packing was studied by simulating the selective hydrogenation of butadiene in presence of butane and benzene on PdNiCe structured catalytic packing. The catalytic packing operated in a co-current downflow - cooled by the wall (temperature-programmed) - trickle-bed reactor. The model takes into account the presence of mass and heat transfer resistance and uses a heterogeneous kinetic rates model. The program solved, point by point, the mass and energy differential equation of a bidimensional plug flow type reactor model using a numerical method. To calculate the liquid concentrations, an adiabatic flash implemented along the reactor length takes into account the gas-liquid equilibrium. Several mass and heat transfer correlations and own kinetic and deactivation rate constants were used. The program calculates the volume of the reactor for a given conversion and characteristic of the catalysts, as well as the radial and axial profiles of concentrations, temperature, and activities along the cycle length. The sensitivity study performed for the heat transfer parameter demonstrated the influence of benzene, reactor geometry, and the type of heat transfer correlation used in activity, selectivity and stability for the selective hydrogenation of butadiene to butane. The effective heat radial conductivities obtained from published correlations are compared to our experimental values. © 2010 Elsevier Ltd. All rights reserved.

The phlebotomine sand fly Lutzomyia velezi sp.nov. was described and illustrated from male specimens collected by light trap in the Reserva Natural Cañon del Río Claro in the Central Cordillera of the Colombian Andes. The new species belongs to the series sanguinaria of the subgenus Helcocyrtomyia, which is represented in Colombia by Lutzomyia cirrita, Lutzomyia hartmanni, Lutzomyia sanguinaria, Lutzomyia scorzai, Lutzomyia sp. of Pichindé and Lutzomyia tortura. The new species can be differentiated from others of the subgenus by the combination of the following characteristics: long antennal ascoids, reaching level of the papilla, coxite with a single basal seta and fifth palpomere longer than or equal to the sum of the lengths of the third and fourth palpomeres.

In this paper we show that the C*-algebra generated by radial Toeplitz operators with (Formula presented.)-symbols acting on the Fock space is isometrically isomorphic to the C*-algebra of bounded sequences uniformly continuous with respect to the square-root-metric (Formula presented.). More precisely, we prove that the sequences of eigenvalues of radial Toeplitz operators form a dense subset of the latter C*-algebra of sequences. © 2016 Springer International Publishing

Objective: To describe the factors that influence over hypertensive patient's adherence to pharmacological and non pharmacological treatment. COOMEVA. Sincelejo, 2006. Materials and methods: Descriptive-quantitative transversal study. The sample was composed of 276 patients between the ages of 35 and 106 years old, 68% masculine and 32% feminine, whom were chosen through a simple random sampling. The information was obtained through a validated instrument and processed by SPSS software. Results: The average age was 61.5 years old. 98% of the participants have no risk factors for adherence problem. Within the factors that influence over treatment adherence, 95% of the patients manifest to have family support in order to complete the treatment, 98% have always had knowledge about their follow up appointments and think that the treatment has been beneficial. 52% of the patients express that having Arterial Hypertension worries them and generates distress because of the changes they must make in their daily life. Conclusions: The therapeutic adherence found in the study reflects that the patients are committed to their health care and attentive pleasant behavior from the health personnel motivates adherence to treatment. However, the study reports that 52% of the patients need strengthening strategies in assuming their disease in order to not be affected emotionally by it.

In this paper we present a calculation of the binding energy of a donor impurity in a cylindrical GaAs-Ga0.6Al0.4As quantum well wire (QWW) as a function of an applied magnetic field for different wire radii and different positions of the donor. The model considers an infinite length QWW with a carrier that is confined laterally by a parabolic potential and the presence of a uniform magnetic field applied parallel to the wire axis. The 1s-like impurity state is considered using the effective-mass approximation within the variational approach. We found that for a given wire radius the binding energy of the impurity increases with the magnetic field and that for a given magnetic field value it decreases with wire radius. Our results are in good agreement with previous theoretical reports. © 2010 Elsevier B.V.
