Características relevantes de la simulación energética de viviendas unifamiliares

Energy simulation systems allow analyzing the environmental quality and demand of buildings, but they must have reliable and proper procedures. This paper identifies relevant conditions of energy simulation systems for the study of single-family homes, based on the analysis of a dozen programs and various experiences in south central Chile. A review of capabilities was conducted, simulating the same case in all systems and making interviews with expert users. Besides it studied the incidence of background data and different strategies for analysis the environmental performance of housing. Revealing significant characteristics in the energy study of detached residential buildings. Finally it suggests reviewing certain conditions to ensure the effectiveness of the environmental analysis and subsequent actions.Los sistemas de simulación energética de edificios permiten analizar la calidad y demanda ambiental de las construcciones, pero deben contar con procedimientos fiables y pertinentes.

The management of acute venous thromboembolism in clinical practice. Results from the European PREFER in VTE Registry

Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in Europe. Data from real-world registries are necessary, as clinical trials do not represent the full spectrum of VTE patients seen in clinical practice. We aimed to document the epidemiology, management and outcomes of VTE using data from a large, observational database. PREFER in VTE was an international, non-interventional disease registry conducted between January 2013 and July 2015 in primary and secondary care across seven European countries. Consecutive patients with acute VTE were documented and followed up over 12 months. PREFER in VTE included 3,455 patients with a mean age of 60.8 ± 17.0 years. Overall, 53.0 % were male. The majority of patients were assessed in the hospital setting as inpatients or outpatients (78.5 %). The diagnosis was deep-vein thrombosis (DVT) in 59.5 % and pulmonary embolism (PE) in 40.5 %. The most common comorbidities were the various types of cardiovascular disease (excluding hypertension; 45.5 %), hypertension (42.3 %) and dyslipidaemia (21.1 %). Following the index VTE, a large proportion of patients received initial therapy with heparin (73.2 %), almost half received a vitamin K antagonist (48.7 %) and nearly a quarter received a DOAC (24.5 %). Almost a quarter of all presentations were for recurrent VTE, with >80 % of previous episodes having occurred more than 12 months prior to baseline. In conclusion, PREFER in VTE has provided contemporary insights into VTE patients and their real-world management, including their baseline characteristics, risk factors, disease history, symptoms and signs, initial therapy and outcomes

Promoting an Active Life Through Threatening Communication: Effects on College Student’s Emotions

This pilot study was aimed to evaluate the acute effects of a sedentary-focused intervention through threatening communication on college student’s emotions. Thirty-six female college students (mean age 20.8 2.7 years) who participated voluntarily where exposed to five neutral and five sedentary-related threatening video messages. In order to evaluate the emotional impact of the messages, the subjects’ faces were recorded and analyzed during these expositions using a facial expression recognition software (FaceReader System 4.0), and assessing the time-lapse percentage of the following basic expressions: neutral, sad, angry, surprised, scared, and disgusted. Compared to the neutral messages, a non-significant increase in sad, angry,and disgusted expressions were observed after threatening intervention; nevertheless, the effect size (d) for the disgusted expression was .832. Moreover, the time-lapse percentage of neutral facial expression decreased after threatening messages althoughno statistical significance was reached (p= .174)

Estimation by PLFA of Microbial Community Structure Associated with the Rhizosphere of Lygeum spartum and Piptatherum miliaceum Growing in Semiarid Mine Tailings

The objective of this study was to compare the microbial community composition and biomass associated with the rhizosphere of a perennial gramineous species (Lygeum spartum L.) with that of an annual (Piptatherum miliaceum L.), both growing in semiarid mine tailings. We also established their relationship with the contents of potentially toxic metals as well as with indicators of soil quality. The total phospholipid fatty acid (PLFA) amount was significantly higher in the rhizosphere soil of the annual species than in the rhizosphere soil of the perennial species. The fungal/bacterial PLFA ratio was significantly greater in the perennial species compared to the annual species. The fatty acid 16:1ω5c, the fungal/bacterial PLFA ratio and monounsaturated/saturated PLFA ratio were correlated negatively with the soluble contents of toxic metals. The cyc/prec (cy17:0 + cy19:0/16:1ω7 + 18:1ω7) ratio was correlated positively with the soluble contents of Pb, Zn, Al, Ni, Cd, and Cu. The results of the PLFA analysis for profiling microbial communities and their stress status of both the plant species indicate that perennial and annual gramineous species appear equally suitable for use in programmes of revegetation of semiarid mine tailings
