1. ANALYTICAL EXPRESSIONS FOR THE CONCENTRATION AND CURRENT IN THE REDUCTION OF HYDROGEN PEROXIDE AT A METAL-DISPERSED CONDUCTING POLYMER FILM
A mathematical model describing the reduction of Hydrogen peroxide (H2O2) to water in a metal dispersed conducting polymer film is discussed. The model is based on a system of reaction-diffusion equations containing a non-linear term related to Michaelis-Menten kinetics of the enzymatic reaction. The approximate analytical expressions corresponding to the co

2. La vida social de la energía: apuntes para el estudio territorializado de las transiciones energéticas
Abstract This paper presents a theoretical and methodological proposal for the sociological study of energy transition towards non-conventional renewable energy, as a process of induced transformation related to climate change, whose courses of action are not exempt from socio-technical controversies. The proposal is based on a four-year research program on

3. New insights into genomic selection through population-based non-parametric prediction methods
ABSTRACT: Genome-wide selection (GWS) is based on a large number of markers widely distributed throughout the genome. Genome-wide selection provides for the estimation of the effect of each molecular marker on the phenotype, thereby allowing for the capture of all genes affecting the quantitative traits of interest. The main statistical tools applied to GWS

6. Milk production and its relationship with milk composition, body and udder morphological traits in Bedouin goat reared under arid conditions
ABSTRACT. This research aims to assess the performances of lactating Bedouin goat under arid conditions, focusing on the relationship of milk yield with body and udder morphology and growth traits. Fourteen goats and their kids were followed during early lactation (90 days post-partum). Mean daily milk yield was 0.56 kg. Milk fat, proteins, lactose, solids n

7. Efficient numerical method for solution of boundary value problems with additional conditions
Abstract An efficient numerical method for solution of boundary value problems with additional condition is presented. The approach is based on the shooting method but the procedure of seeking “the proper shot” allows one to satisfy “additional” boundary conditions. General considerations are illustrated by a real example. The computational example c

8. Lifestyle intervention using the psychoeducational approach is associated with greater cardiometabolic benefits and retention of individuals with worse health status
ABSTRACT Objective This study aimed to compare the effects of two lifestyle intervention programs for type 2 diabetes mellitus (T2DM) prevention – traditional or interdisciplinary psychoeducation-based intervention – in daily habits and cardiometabolic risk factors and investigate the role of the psychoeducational approach for the retention of individu

9. In-house method validation and occurrence of alpha-, beta-endosulfan, endosulfan sulphate, lambda-cyhalothrin, procymidone and trifluralin residues in strawberry
A method for determination of organohalogen pesticides in strawberry by gas chromatography with electron capture detection was validated and applied in a monitoring program. Linearity, matrix effects, and day effect were evaluated for the analytes alpha-endosulfan, beta-endosulfan, endosulfan sulphate, lambda-cyhalothrin, procymidone, and trifluralin. The li

10. Establishing the minimal number of virtual reality simulator training sessions necessary to develop basic laparoscopic skills competence: evaluation of the learning curve
Introduction Medical literature is scarce on information to define a basic skills training program for laparoscopic surgery (peg and transferring, cutting, clipping). The aim of this study was to determine the minimal number of simulator sessions of basic laparoscopic tasks necessary to elaborate an optimal virtual reality training curriculum. Materials a

Programa de intervenção interdisciplinar em hábitos de vida em indivíduos de risco cardiometabólico: análise de fatores dietéticos associados à melhora do metabolismo glicídico / Interdisciplinary intervention program on lifestyle in individuals at cardiometabolic risk: analysis of dietary factors associated with improvement in glucose metabolism
Introduction: Cardiometabolic diseases are global public health problems with social and economic repercussions. Unhealthy diet is seen as one of the main modifiable risk factors, being of central importance for the prevention of these diseases. Despite the evidence that certain nutrients are associated with diseases, causal relationships are still under dis
