This article develops an estimation of the price elasticity of demand of a medication "type" for treating depression. This disorder affects physically and mentally a big part of the population around the world. This disorder is considered an important public health problem whose preva-lence has been increasing. For the purpose of this research two econometric models of vectors were estimated for the previous period of the issuance of Circular 03 of 2013, which regulates the price of medications in Colombia. The outcomes of the estimation show a non-significant price elasticity of 0.35 %, that is to say, changes in price do not generate the expected response in demand. This result suggests that the company, which produces this type of medication, exerts significant power in the market. Therefore, this result proves the need to implement the Circular.

Introduction: The gold standard to estimate individual usual intake is the mean of multiple day’s intake. This estimation procedure is based on Beaton´s model, who consider independence and two sources of variation: between and within subjects. There are evidences and physiological arguments against validity of Beaton´s hypothesis, this fact could have relevant effects in dietetic assessment. Subjects and Methods: A food consumption of 43 middle class university women was recorded during 28 days. They were trained in order to assure quality records. Results: Low values in energy intake were reported, and no differences between energy intake during weekend and weekdays was observed. Considering reported intakes for each person as a time series, no autocorrelations was observed considering lags within 1 to 7 days. Differences in within subjects variances was observed. Conclusion: Deficiencies in subject´s energy intake corresponds to disorders in university students´ nutrition, such deficiencies could be the explanation of the observed independence in daily energy intake despite evidences of the existence of correlations reported in different papers. The hypothesis of variance homogeneity was not true, so it was not correct to talk about a “within variance”, instead a population´s probability distributions for variances was considered, as a consequence Beaton´s model must be modified. A probability distribution to characterize the number of days needed to estimate energy intake for subjects in population was considered. © 2016, Sociedad Chilena de Nutricion Bromatologia y Toxilogica.

This paper presents and discusses the behavior of standard groups and piled rafts constructed with helical screw piles founded in the typical soil of the Federal District of Brazil (DF). The paper initially characterizes the soil deposit of a new Experimental Site in the DF via laboratory (standard characterization, triaxial) and field (standard penetration and flat dilatometer) tests. It then moves to explain a recently adjusted (hypoplasticity) constitutive model that takes on consideration the inherent soils structure to simulate the behavior of this typical geotechnical material. The model was calibrated via point load test analyses and incorporated into a finite element methodology (FEM) routine internal to the traditional Abaqus software. Real scale field load tests on standard pile groups and piled rafts executed with this pile type were carried out in the new site. FEM analyses were used to calibrate the model and to expand the knowledge on the shearing mechanisms, generated stresses, displacement fields, load sharing, group efficiency, and on the contribution of the supporting raft to the overall systems performance. Conclusions of practical and academic interest are given for this new type of foundation employed in the region. © 2015 Elsevier Ltd.

Natural non-renewable resources, such as minerals, are becoming increasingly depleted against a backdrop of intense industrialisation. Through the exergy analysis and thermoeconomic tools it is possible to assign a figure to the degree of depletion. This is because the exergy replacement cost represents the effort needed by humankind to return minerals to their original conditions from the "commercially dead state", Thanatia. The authors undertake an evaluation of the ten most significantly produced minerals in Colombia, since 1990. Via the 2011 mineral balance, this paper shows that the highest exergetic losses are in the extraction for export and not national consumption rates. The loss in mineral wealth, quantified in exergy terms for 2011 is 119.2Mtoe (4.99×109GJ) and has, since 1990, accumulated to 1,543.4Mtoe (6.46×1010GJ). In converting these losses into economic terms, it becomes clear that the nation must re-think its mineral export strategy, if it is develop sustainably. © 2015 Elsevier Ltd.

Companies involved in water and forest resource extraction in Colombia are obliged to compensate for any resulting impacts stemming from their activities, as agreed with the environmental authorities. Compensation usually relates to reforestation or the development of public service infrastructure. However, these initiatives should be more relevant to the local community and ensure that the protection of biodiversity is efficiently undertaken and optimized to support the greatest number of benefits to fauna and flora and the provision of ecosystem services. This paper shows how a partnership between Mansarovar Energy Colombia Ltd., a heavy oil extraction company, and the national and local environmental authorities, resulted in the establishment of buffer zones to support the conservation of the Regional Natural Park "Serranía de las Quinchas". In total one thousand hectares were added to the already existing 21,000 ha that legally constitute the park. This synergy led to a greater impact within the local community, compared to when each entity worked separately. Copyright 2016, Society of Petroleum Engineers.

Corporate sustainability increasing requires sustainable supply chain management. This concept has been successfully applied in Colombia, where Mansarovar Energy operates, but had not involved the hydrocarbon sector. Mansarovar saw an opportunity for the adoption of a sustainable supply chain model and in 2015 adapted one to meet their specific needs. The resulting Web+, where Mansarovar acted as the anchor company, is still in its pilot stage but results have been encouraging. The model was designed as a voluntary partnership to promote sustainability within supplier and contractor activities that are part of Mansarovar?s supply chain with the support of a certified training/enabler organisation. Ten participants were involved and the seven successfully proposed sustainability projects are estimated to save $117,000 per annum due to the resulting reduction in energy, waste and agro-chemicals consumption and other social or organizational co-benefits. This indicates that sustainable practices are all the more important when oil price drops and are integral to hydrocarbon sector profitability in both the short and long term.

The architecture of a software system is the result of balancing concerns expressed by system stakeholders using a decision-making process. Several industrial approaches have been proposed that recognize the importance of architectural decisions and their rationale, but most do not provide mechanisms to systematically formalize and manage this decision-making. This article proposes a strategy to enrich the activities of software architecture design, by using Business Process Management Notation (BPMN) in a clear, structured and consistent manner to keep the focus on decisions. This strategy consists of (1) an &x0022;as-is&x0022; process definition, analysis and improvement of the original process, and (2) a &x0022;to-be&x0022; process transformation, allowing to derive an enriched process. The approach is illustrated using the security perspective to architectural views in Rozanski and Wood's V&P method. This approach is a step towards the systematic consideration of software architecture design processes as decision-making activities. © 2014 IEEE.

Feature Models are widely used in Software Product Lines to represent commonalities and variabilities in a family of products and to support the interactive configuration of these products. They comprise features and options that can be included in a product and constraints about which combinations of features are allowed. Libraries and frameworks such as SPLOT and FaMa help engineers to determine if a feature model is valid, detect errors in the models and validate if a configuration (i.e., a set of features selected by an user) does not contradict the constraints in the model. Regrettably, these libraries are based on Java and cannot be used in.Net platforms such as the recent Windows Phone systems. For that platforms, there is a Microsoft Solver Foundation (MSF) library that provides a set of solvers such as the used to analyse feature models. This paper explains (1) how to translate feature models and configurations into Constraint Satisfaction Problems in MSF, and (2) how to use that library to determine if a model is valid, enumerate all the valid configurations, and detect core and dead features that may exist in the model. In addition, we present a performance evaluation of the approach. © 2016 IEEE.

"Ecoenvelopes" is about the development of building envelope solutions for tropical humid climates involving passive control of thermal gains on their surfaces, allowing for better internal conditions and comfort without the use of thermal machines. Environmental principles, design, and technological aspects are specifically defined based on the peculiar conditions (geo-climatic, technological, of biodiversity, economic and anthropic) present in the Colombian low altitude regions, marked by constant high temperatures. Thermal and CFD simulations orient the process of experimental verification in a permanent laboratory counting on partnerships and available know-how.
