Optimized delta expansion for relativistic nuclear models

The optimized delta-expansion is a nonperturbative approach for field theoretic models which combines the techniques of perturbation theory and the variational principle. This technique is discussed in the lambda phi(4) model and then implemented in the Walecka model for the equation of state of nuclear matter. The results obtained with the delta expansion are compared with those obtained with the traditional mean field, relativistic Hartree and Hartree-Fock approximations.

Representações sociais como instrumento de informação para a saúde bucal coletiva

In addition to understanding the distribution of the populations’ health-disease process, epidemiology has sought to study the causality associated with this process, which humanity developed over time, and to interpret the narrative of this field of knowledge. A solid review of the literature was done to emphasize the importance of using popular knowledge as a qualitative health-related investigation strategy and to demystify the use of social representations in the field of dentistry. By initiating the design of a new paradigm for understanding the oral health-disease process, which favors the idea that it is also the result of a sociocultural production, knowledge of the circumstances and context in which it is inserted becomes critical for health assessment actions. Although scientific dentistry has advanced the understanding of oral diseases, communication with popular knowledge leaves much to be desired, since most professionals find themselves trapped in a fragmented model of care. Reconstruction of the logic by which the representations of oral health were produced and socialized over time can be considered a relevant and productive purpose of the representations in the dental area.

Green training supporting eco-innovation in three Brazilian companies: practices and levels of integration

Purpose – The purpose of this paper is to show results from the relationship between green/environmental training and the development of three projects of low-carbon eco-innovations in top Brazilian companies. Design/methodology/approach – This study includes three organizational projects for low-carbon eco-innovations in products (A, B and C) with the objective of reducing their impact on GHG emissions, the so-called low-carbon products. Data were collected from several sources of evidence, including in-depth interviews, document analyses and direct observations. Findings – The authors verified that the environmental training interface for mitigating climate change is relevant for the systematic development of low-carbon products in most of the cases studied. Originality/value – Low-carbon eco-innovations are a trend in the corporate world; however, there is not enough literature and practical evidence on this subject. Thus, this paper adds new evidence to the literature.

As contribuições do dialogismo de bakhtin e do signo em umberto eco para o ensino de língua estrangeira

This article discusses the dialogism in Mikhail Bakhtin and the grounds of the linguistic sign in Umberto Eco, with the intention to use the themes and authors, to support the teaching-learning methodologies of foreign language (English and Spanish) at the public school of São Paulo state. The conceptual approach of the two authors allows us to infer that learning a foreign language is effected by the appropriation of utterances and cultural knowledge, pedagogical concept that confronts the traditional method used in the São Paulo school, which is based mainly on grammar teaching and lexicons. The paper derives the theoretical research used to support a dissertation, posing and evaluates preliminary, the integration of traditional theaters in foreign language in public schools, with digital environments (in online courses), and also the educational effects -the use of audiovisual material at the classroom and online learning.

Availability of nutrients, productive properties, and quality of sunflower ( L.) seeds in acid soils amended with different molar ratios between Ca and Mg

Liming is indispensable in acid soils for amending acidity; however, the technique may alter the cation balance in soil and, consequently, may limit the availability and uptake of nutrients. We aimed to evaluate different molar ratios between calcium (Ca) and magnesium (Mg) on the availability of soil nutrients and their influence on the productive properties of sunflower and seed quality. The experiment was carried out in a greenhouse under two types of contrasting soils and six molar combinations of CaCO3and MgCO3 in amendment of soil acidity to raise base saturation to 70%. After incubation, soil analysis was undertaken to verify the ratios obtained and nutrient availability. Morphological and production variables were analyzed at the end of the experiment, as well as accumulation of nutrients in the achenes and their physiological quality. In spite of equal base saturation between the types of soil, there were differences in the available contents of these cations. The increase in the Ca contents limited the Mg contents to the critical level of the sunflower. This result had a negative influence on the production properties of sunflower and physiological quality. In contrast, there was a compensation of the crop with greater accumulation of nutrients in the achenes under lower yield.

An Affordable, Pratical Eco-House

An eco-house or zero-energy house is not a new concept- houses with extremely low impact on their surroundings and good use of local resources have been around for centuries. This particular eco-house is designed to offer full modern services and comforts while consuming very low energy and few expensive building materials. Ideally, someone would be able to use this thesis as a blueprint for actual construction.

Particulate composite based on coconut fiber and castor oil polyurethane adhesive: An eco-efficient product

This paper presents a study on the potential use of coconut fiber as material to produce particleboards, with two different densities (0.8 g/cm(3) and 1.0 g/cm3), using castor oil-based polyurethane adhesive and urea-formaldehyde. The quality of the product that can be produced by industry was evaluated according to the normative NBR 14.810:2006, where density, thickness swell (TS), absorption, modulus of elasticity (MOE), modulus of rupture (MOR) in static bending and internal bond (IB) were determined. From the results, there was a decrease in TS and increase in MOR of coconut fiber panels with polyurethane resin panels compared with coconut fiber and resin urea-formaldehyde. Scanning microscopy electronic images (SEM) indicated that castor oil-based polyurethane adhesive occupies the gaps between the particles, a factor that contributes to improved physical and mechanical properties of the panels. The assessment of durability through accelerated aging tests shows that panels protected with waterproofing material can be used in environments that have contact with moisture.

Anti-Aversive Effects of Cannabidiol on Innate Fear-Induced Behaviors Evoked by an Ethological Model of Panic Attacks Based on a Prey vs the Wild Snake Epicrates cenchria crassus Confrontation Paradigm

Several pharmacological targets have been proposed as modulators of panic-like reactions. However, interest should be given to other potential therapeutic neurochemical agents. Recent attention has been given to the potential anxiolytic properties of cannabidiol, because of its complex actions on the endocannabinoid system together with its effects on other neurotransmitter systems. The aim of this study was to investigate the effects of cannabidiol on innate fear-related behaviors evoked by a prey vs predator paradigm. Male Swiss mice were submitted to habituation in an arena containing a burrow and subsequently pre-treated with intraperitoneal administrations of vehicle or cannabidiol. A constrictor snake was placed inside the arena, and defensive and non-defensive behaviors were recorded. Cannabidiol caused a clear anti-aversive effect, decreasing explosive escape and defensive immobility behaviors outside and inside the burrow. These results show that cannabidiol modulates defensive behaviors evoked by the presence of threatening stimuli, even in a potentially safe environment following a fear response, suggesting a panicolytic effect.
