Neutrino masses and the scalar sector of a B-L extension of the standard model

We consider an electroweak model based on the gauge symmetry SU(2)(L) circle times U(1)(Y') circle times U(1)(B-L) which has right-handed neutrinos with different exotic B - L quantum numbers. Because of this particular feature we are able to write Yukawa terms, and right-handed neutrino mass terms, with scalar fields that can develop vacuum expectation values belonging to different energy scales. We make a detailed study of the scalar and the Yukawa neutrino sectors to show that this model is compatible with the observed solar and atmospheric neutrino mass scales and the tribimaximal mixing matrix. We also show that there are dark matter candidates if a Z(2) symmetry is included.

Frugivory and Seed Dispersal by Northern Pigtailed Macaques (Macaca leonina), in Thailand

Tropical rain forest conservation requires a good understanding of plant-animal interactions. Seed dispersal provides a means for plant seeds to escape competition and density-dependent seed predators and pathogens and to colonize new habitats. This makes the role and effectiveness of frugivorous species in the seed dispersal process an important topic. Northern pigtailed macaques (Macaca leonina) may be effective seed dispersers because they have a diverse diet and process seeds in several ways (swallowing, spitting out, or dropping them). To investigate the seed dispersal effectiveness of a habituated group of pigtailed macaques in Khao Yai National Park, Thailand, we examined seed dispersal quantity (number of fruit species eaten, proportion in the diet, number of feces containing seeds, and number of seeds processed) and quality (processing methods used, seed viability and germination success, habitat type and distance from parent tree for the deposited seeds, and dispersal patterns) via focal and scan sampling, seed collection, and germination tests. We found thousands of seeds per feces, including seeds up to 58 mm in length and from 88 fruit species. Importantly, the macaques dispersed seeds from primary to secondary forests, via swallowing, spitting, and dropping. Of 21 species, the effect of swallowing and spitting was positive for two species (i. e., processed seeds had a higher % germination and % viability than control seeds), neutral for 13 species (no difference in % germination or viability), and negative (processed seeds had lower % germination and viability) for five species. For the final species, the effect was neutral for spat-out seeds but negative for swallowed seeds. We conclude that macaques are effective seed dispersers in both quantitative and qualitative terms and that they are of potential importance for tropical rain forest regeneration. © 2013 Springer Science+Business Media New York.

Male Homosexuality in Brazilian Indexing Languages: Some Ethical Questions

Studies on ethics in information organization have deeply contributed to the recognition of the social dimension of Information Science. The subject approach to information is linked to an ethical dimension because one of its major concerns is related to its reliability and usefulness in a specific discursive community or knowledge domain. In this direction, we propose, through an exploratory research design with qualitative and inductive characteristics, to identify the specific terminology that Brazilian indexing languages allow for terms relating to male homosexuality. We also analyzed the terms assigned to papers published in the Journal of Homosexuality, Sexualities and Journal of Gay & Lesbian Mental Health between the years 2005 to 2009. From this analysis of terms and the Brazilian indexing languages, we see (1) the Brazilian context, (2) imprecision in the terminology, (3) indications of prejudices disseminated by political correctness, (4) biased representation of the subject matter, (5) and the presence of figures of speech.

Pedagogia do esporte: livro didático aplicado aos jogos esportivos coletivos

The study deals with the pedagogical possibilities of text books as a resource for Physical Education (PE) classes based on sports, specifically team sports. It started from a bibliographical review on the cited terms and after that we advanced our studies in order to propose a didactic text book on Team Sports for PE classes considering two benchmarks: one technical-tactic and the other social-educational. In order to do so, we used methods from linguistics, and the development of a Didactic Sequence allowed the selection and distribution of the contents to be presented in the book in an orderly and judicious way. The focus in Team Sports is justified by its social-cultural insertion and by the need to transform recent studies into new pedagogical procedures for practicing them. The didactic text book, as well as the adequate preparation of the professionals who will use it, is pointed out as facilitator in the process of teaching, experiencing and learning team sports.

Cromatografia gasosa ultrarrápida: uma visão geral sobre parâmetros, instrumentação e aplicações

Since the introduction of GC there has been an ongoing interest in reducing time of analysis resulting in new terms and definitions such as ultra fast gas chromatography (UF-GC). One of the most used definitions describes UF-GC as a technique that combines the employment of short narrow bore column with very fast temperature programming rates producing chromatographic peaks in the range of 50 ms and allowing separations times in 1-2 min or less. This paper summarizes the analytical approaches, the main parameters involved and the instrumentation towards UF-GC.

Capacidade, dotação, talento, habilidades: uma sondagem da conceituação pelo ideário dos educadores

Embora o escopo deste trabalho seja de origem teórica, relata um estudo exploratório que busca situar a base de conceituação em Educação Especial para alunos Dotados e Talentosos, no Brasil, captando as definições compreendidas por profissionais da educação pela sondagem de sua opinião sobre que termos e expressões são usados, com que significados e em que situações. Os sujeitos incluíam 80 educadores interessados ou envolvidos na área (Grupo A) e 107 professores da rede pública no interior de São Paulo (Grupo B). Há poucas diferenças de opinião entre os sujeitos, nos dois grupos, com algumas exceções, principalente em questões relacionadas a nível de conhecimento e familiaridade com referencial teórico. Ambos os grupos indicam conceituação confusa, notadamente para os termos oficiais, superdotação e altas-habilidades; a maior carga de rejeição e exploração na mídia é alocada a superdotação. Os conceitos alta capacidade, alto desempenho e dotação são definidos em consonância com o referencial básico, que diferencia capacidade natural de capacidade adquirida; Talento reflete a ambiguidade encontrada na área, referindo-se, ao mesmo tempo, a capacidade natural e capacidade adquirida.

INFLUENCE of THE EVAPORATOR POSITION IN STATIC DOMESTIC REFRIGERATORS

The temperature and velocity distributions of the air inside the cabinet of domestic refrigerators affect the quality of food products. If the consumer knows the location of warm and cold zones in the refrigerator, the products can be placed in the right zone. In addition, the knowledge of the thickness of thermal and hydrodynamic boundary layers near the evaporator and the other walls is also important. If the product is too close to the evaporator wall, freezing can occur, and if it is too close to warm walls, the products can be deteriorated. The aim of the present work is to develop a steady state computational fluid dynamics (CFD) model for domestic refrigerators working on natural convection regime. The Finite Volume Methodology is chosen as numerical procedure for discretizing the governing equations. The SIMPLE-Semi-Implicit Method for Pressure-Linked Equations algorithm applied to a staggered mesh was used for solving the pressure-velocity coupling problem. The Power-Law scheme is employed as interpolation function for the convective-diffusive terms, and the TDMA-Tri-Diagonal Matrix Algorithm is used to solve the systems of algebraic equations. The model is applied to a commercial static refrigerator, where the cabinet is considered an empty three-dimensional rectangular cavity with one drawer at the bottom of the cabinet, but without shelves. In order to analyze the velocity and temperature fields of the air flow inside the cabinet the evaporator temperature, Te, was varied from -20 degrees C to 0 degrees C, and nine different evaporator positions are evaluated for evaporator temperature of -15 degrees C. The cooling capacity of the evaporator for the steady state regime is also computed for each case. One can conclude that the vertical positioning of the evaporator inside the cabinet plays an important role on the temperature distribution inside the cabinet.

Utilização de resíduos e derivados de madeira para confecção de uma guitarra elétrica

The residues generation is a quite serious problem in several industrial areas and also in the lumbering area. The search for the elimination or reduction of the volume of generated residues is endless, however limited, resulting in the search for a proper destination or better use, instead of simply burning it. A lot of uses and services are commonly proposed, but with low aggregated value to the residue. This work shows the usage viability of different discarded residues and wood composites in the production of an electric guitar. Cupiúba, ipê and jatobá residues have been used besides wood composites of pinus. The residues and wood composites have shown appropriate resistance, surfacing quality and design terms, and could be used to substitute the traditionally wood used in the production of the instrument as well as in other products of similar characteristics and with larger aggregated value.

A escrita de si na formação em educação física

The Self-writing on the formation in Physical Education Abstract: The objective of this article is to create a field of quarrels about Self-writing on the context of professional graduation in Physical Education, recognizing this writing exercise as a potential way to find what escapes to the knowledge terms and that force the thought to think the consistency of the meeting that across the graduation process. From this point, we want to reach the demands that are excluded in the formation speech - the demands of sensibility - recognizing them as expressions of an incarnate knowledge. Beyond the theoretical skills, the Selfwriting helps us to build a deeper understanding of the professional graduation, not because it play on a speech upon the practices, but for giving opening to the writing of the intensities forged in the meeting between practice and knowledge - where the professional intervention is installs.
