27. Effect of Nutrient Sources on the Alginate Accumulation in the Culture Liquid of Azotobacter vinelandii D-05 and Obtaining Biocomposite Materials
ABSTRACT Using the classic biotechnological methods, the dependence of A. vinelandii D-05 culture alginate production from the media carbon and nitrogen content was investigated. The maximal alginate production was observed during cultivation bacterium in the medium with 2 to 4% of sucrose, but the maximal growth was found in the medium with 4% glucose. It w

28. Uso de procesos pirometalúrgicas para la obtención de renio
ABSTRACT Rhenium is a metal that has different obtainment methods. The most used comes from molybdenite roasting. Traditional pyrometallurgical methods like oxidizing roasting are applied, but there are also innovative pyrometallurgical methods as is roasting with carbothermic reduction. This paper presents the behavior of rhenium onto two different roasting

30. Efficacy indicators of four methods in outpatient addiction treatment
Abstract Background In Portugal, as far as we know, there are no recent studies that evaluated the comparative efficacy of therapeutic modalities in addiction problems by reference to a holistic and psychosocial model of effectiveness. Objectives Using a sample of Portuguese patients in outpatient treatment for drug and alcohol abuse, this study aimed to

31. Impact of Myocardial Revascularization Method on Smoking Cessation: Coronary Artery Bypass Grafting versus Percutaneous Coronary Intervention
Abstract Introduction: Smoking is a serious public health issue, being a precursor of heart disease and a predictor of sudden death due to myocardial ischemia. Major events in the patient's health can lead to radical changes in habits and the choice for different myocardial revascularization methods might differently impact smoking cessation and relapse. O

32. Dynamic Compressive Strength and Failure of Natural Lake Ice Under Moderate Strain Rates at Near Melting Point Temperature
Abstract This paper presents a series of uniaxial compressive experiments on natural lake ice under moderate strain-rate in the range of 10−1 to 102 s−1 at −0.1 °C. Natural lake ice samples of 8 cm by 8 cm in cross section and 20 cm high were used to investigate strain-rate dependence of uniaxial compressive strength and flaw effects on ice strength u

33. Longitudinal model for categorical data applied in an agriculture experiment about elephant grass
ABSTRACT Experiments where the response is a categorical variable are usually carried out in many fields such as agriculture. In addition, in some situations this response has three or more levels without an order between them characterizing a multinomial (nominal) response. Statistical models for scenarios where the observations of a nominal response can be

34. Current alcohol dependence and emotional facial expression recognition: a cross-sectional study
Abstract Background Several studies have demonstrated that chronic and excessive alcohol use causes social cognition deficits. Objectives Thus, the aim of the current study is to assess the associations between emotional facial expression recognition and current alcohol dependence. Methods The sample consisted of two groups: one was composed by current

35. Structural Characterization of ZnTe Grown by Atomic-Layer-Deposition Regime on GaAs and GaSb (100) Oriented Substrates
This work presents the characterization of ZnTe nanolayers grown on GaAs and GaSb (100) substrates by the Atomic Layer Deposition (ALD) regime. Under certain conditions, the alternating exposition of a substrate surface to the element vapours makes possible the growth of atomic layers in a reactor where the atmosphere is high-purity hydrogen. ZnTe was grown

36. INTRODUCING A CAUSAL PAR( p ) MODEL TO EVALUATE THE INFLUENCE OF CLIMATE VARIABLES IN RESERVOIR INFLOWS: A BRAZILIAN CASE
ABSTRACT The Brazilian electricity energy matrix is essentially formed by hydraulic sources which currently account for 70% of the installed capacity. One of the most important characteristics of a generation system with hydro predominance is the strong dependence on the inflow regimes. Nowadays, the Brazilian power sector uses the PAR(p) model to generate s
