Mexico: industrial policies and the production of information and communication technology goods and services

This study investigates the extent to which the digital boom has had repercussions on productive activity, in terms of both manufacturing (ict goods) and services (ict services), in addition to its potential ramifications in the rest of the Mexican economy. Input-output matrices are used and compared to those of Brazil and the United States. Mexico has fallen behind, particularly in the production of ict goods, and the productive chains of this activity have weakened. The ict services sector offers much greater potential than has been exploited thus far, with the advantage that it involves comparatively more value added and has major diversification possibilities. It is considered essential to find more effective industrial policies targeted on the ict goods and services sectors; but the experience of countries such as Brazil, which have applied more proactive approaches with mixed results, suggests that this will be challenging.

Identification and phylogenetic inferences on stocks of sharks affected by the fishing industry off the Northern coast of Brazil

The ongoing decline in abundance and diversity of shark stocks, primarily due to uncontrolled fishery exploitation, is a worldwide problem. An additional problem for the development of conservation and management programmes is the identification of species diversity within a given area, given the morphological similarities among shark species, and the typical disembarkation of processed carcasses which are almost impossible to differentiate. The main aim of the present study was to identify those shark species being exploited off northern Brazil, by using the 12S-16S molecular marker. For this, DNA sequences were obtained from 122 specimens collected on the docks and the fish market in Bragança, in the Brazilian state of Pará. We identified at least 11 species. Three-quarters of the specimens collected were either Carcharhinus porosus or Rhizoprionodon sp, while a notable absence was the daggernose shark, Isogomphodon oxyrhyncus, previously one of the most common species in local catches. The study emphasises the value of molecular techniques for the identification of cryptic shark species, and the potential of the 12S-16S marker as a tool for phylogenetic inferences in a study of elasmobranchs.

Efeito da adição de culturas láticas mesofílicas sobre a qualidade do queijo de coalho

O objetivo deste trabalho foi avaliar a característica do queijo de coalho, produzido a partir do leite bovino pasteurizado, mediante a utilização de bactérias láticas mesofílicas do gênero Lactococcus lactis ssp. cremoris e Lactococcus lactis ssp. lactis específicas. As culturas láticas oriundas do Banco de Bactérias Láticas da Universidade Estadual do Ceará foram ativadas junto às instalações do Laboratório de Bactérias Láticas da Universidade Federal Rural da Amazônia-UFRA, Campus de Belém. As culturas láticas foram ativadas durante três dias consecutivos em Leite Desnatado Reconstituído (LDR) 12% esterilizado e incubadas a 30 °C ± 2 °C, até a coagulação do leite. Após reativação, a cultura industrial foi obtida pela transferência do inoculo de 1% (v/v) para frascos de vidros contendo 500 ml de LDR 12% esterilizado, seguida de incubação a 30 °C ± 2 °C até a coagulação do leite, em seguida a cultura (fermento lático) foi adicionada diretamente no tanque de fabricação contendo o leite pasteurizado, mantendo-se a proporção de 1:1. Para avaliação tecnológica foram utilizados as seguintes culturas láticas isoladas de leite cru: Lactococcus lactis ssp. lactis (LL); Lactococcus lactis (atípico) (LLA); Lactococcus lactis ssp. cremoris (atípico) (LLCA); Lactococcus lactis ssp. cremoris (LLC),. As porções de Amostras foram retiradas, colocadas em processador de alimentos e processadas até formar uma amostra. Em seguida, foram acondicionadas em frascos estéreis, identificadas e mantidas em freezer para posterior análises de determinação do extrato seco, umidade (%), extrato seco total (EST), gordura (G), gordura no extrato seco (GES), acidez, pH, cloretos, nitrogênio total (NT), nitrogênio solúvel em pH 4,6, nitrogênio solúvel em TCA 12%. O índice de proteólise ou extensão da maturação foi avaliado pela divisão do NT. Para o teste de aceitação utilizou-se a escala hedônica estruturada de nove pontos, para avaliar o produto quanto ao aroma, aspecto geral, gosto e textura. O teste de fritura de acordo com metodologia descrita por Cavalcante et al., (2007). As análises microbiológicas das amostras de queijos experimentais nos 1º e 30º dia de maturação, encaminhadas ao Laboratório Central – LACEN, Divisão de Análises de Produtos – DEP. E consistiram em Contagem de bactérias Aeróbias Mesófilas, Determinação de Coliformes. Para o teste de fritura não houve análise estatística. O delineamento utilizado foi o Inteiramente Casualisado e foi utilizada a metodologia de modelos mistos para dados longitudinais, com objetivo de modelar a estrutura de (co)variância entre medidas coletadas na mesma unidade experimental em tempos diferentes, por meio do modelo y_ijk=μ+α_i+ δ_(i)+β_k+ α β_ik+ε_ijk. Utilizando-se o programa estatístico Statistical Analysis Systems - SAS (SAS INSTITUTE INC., 1992). Os tratamentos LL e LLA foram reprovados no teste de fritura. Houve ligação entre a característica derretimento com a umidade, acidez e proteólise. Os queijos que apresentaram maiores valores de proteólise apresentaram maior capacidade de derretimento. As amostras de queijo coalho tiveram boa aceitabilidade no teste de aceitação.

Tubo digestório de Urostreptus atrobunneus (Diplopoda): estrutura e função

Millipedes are macro-arthropods of soil which perform a important role in maintaining the balance of the ecosystem, since they feed on decaying organic matter and because they promotes the soil enrichment, aeration and humidification. These animals are usually found in humid with low light places, under rocks and trunks. The diplopods exoskeleton is much resistant and impregnated with calcium salts. Due the secretion of defense, with strong and unpleasant smell, the animals of this class have few or no predators. Large diplopods populations are not observed, but explosions population can occur for unbalances enviromnmental, by climate change and by use of pesticides that may eliminate potential competitors. In this sense, the millipede Urostreptus atrobrunneus Pierozzi & Fontanetti, 2006, has presented points of infestation in urban centers of Sao Paulo state, causing many disorders of the human population. Because it is a newly described species, little is known of its aspects biological and morphological. Thus, the purpose of this study was to describe the structure and function of the digestive tract of the species U. atrobrunneus by means of histological, histochemistry and ultrastructural techniques. The results demonstrated that the digestive tract of U. atrobrunneus is similar to the descriptions given for other species. The foregut consists of a simple epithelium, composed of cells of different heights, covered by a cuticular intima, leaning on a thin basal membrane, followed by a well-developed muscular layer and an external membrane, around the foregut have a pair of salivary glands. The midgut epithelium has a pseudostratified, supported by a thick basal membrane, followed by a muscular layer and a layer of hepatic cells. The muscle is distributed unevenly coated with an external membrane, this portion is marked by the absence of cuticular intima... (Complete abstract click electronic access below)

Aplicação de coagulantes naturais no tratamento de lixiviado de resíduos urbanos

With the constant increase in the municipal solid waste (MSW) generation, mainly due to the high consumption patterns, it becomes difficult to manage correctly the solid waste and thus minimize their impact on the environment. One of the most problems of the large amount of waste generated is the liquid originated from physical, chemical and biological decomposition process of organic wastes, with dark color and bad smell, called leachate: it can reach the soil, polluting the groundwater and the surface water. Therefore, this study aimed to investigate the process of coagulation/flocculation/sedimentation applied in the treatment of the leachate generated in the not controlled landfill of Presidente Prudente, Sao Paulo...

Aplicação de engenharia tecidual na elevação de seio maxilar: uma revisão sistemática da literatura

The purpose of this literature review is to present the state-of-the-art on the application of tissue engineering techniques in sinus lifts procedures, reporting the influence of these techniques in increasing bone height and volume in the maxillary sinus, and the osseointegration of the implants installed in the grafted areas. PubMed and Scopus databases were searched using the keywords “scaffold” OR “engineered tissue” AND “sinus augmention” OR “sinus floor elevation”. In the initial search 463 articles were selected, of which 19 were selected abstracts reading, with nine papers selected by the end, for evaluation of the application of tissue engineering techniques in sinus lift procedures. Despite the positive results of tissue engineering procedures in sinus floor elevation reported in the selected articles, further studies are still needed, for a better standardization of experimental models and materials used, leading to definitive conclusions about the effects of the application of tissue engineering procedures on bone formation in maxillary sinus lifting procedures.

Programa de educação e prevenção em saúde bucal nas escolas: análise crítica de publicações nacionais

Objective: To conduct a survey on national databases about Oral Health Program (OHP) publications in schools, in the last eleven years. Material and Methods: A survey was conducted in two main bases of national publications in the field of dentistry: Bireme and Scielo. To start the research, it was used the articles theme/subject. In the search, it was used the keywords 'oral health education', 'programs and oral health and dentistry', 'programs and oral health and education'. Results: A total of 20 publications were selected. From these, seven (35%) had the aim to evaluate educational methods used in OHP, 12 (60%) evaluated the effectiveness of the OHP itself developed in the school and one (5%) reported the experience of OHP. Only two publications did not get positive results and the other eighteen obtained advantageous results. Conclusion: In the national scientific literature, there are few publications about the subject in question, suggesting that the successful experiences about OHP in schools must be published to be replicated in other parts of Brazil.

Market and Welfare Effects of Mandatory Country-Of-Origin Labeling in the Specialty Crops Sector

Public Law 107-171 of the U.S. Farm Security and Rural Investment Act of 2002 required country-of-origin labeling (COOL) for beef, lamb, pork, fish, perishable agricultural commodities (fresh and frozen fruits and vegetables) and peanuts. While a goal of this law was to benefit domestic consumers by allowing them to make informed consumption decisions, the effects of COOL on the interest groups involved have been the subject of a heated on-going debate.

MATHEMATICAL ANALYSIS OF MAXIMUM POWER GENERATED BY PHOTOVOLTAIC SYSTEMS AND FITTING CURVES FOR STANDARD TEST CONDITIONS

The rural electrification is characterized by geographical dispersion of the population, low consumption, high investment by consumers and high cost. Moreover, solar radiation constitutes an inexhaustible source of energy and in its conversion into electricity photovoltaic panels are used. In this study, equations were adjusted to field conditions presented by the manufacturer for current and power of small photovoltaic systems. The mathematical analysis was performed on the photovoltaic rural system I- 100 from ISOFOTON, with power 300 Wp, located at the Experimental Farm Lageado of FCA/UNESP. For the development of such equations, the circuitry of photovoltaic cells has been studied to apply iterative numerical methods for the determination of electrical parameters and possible errors in the appropriate equations in the literature to reality. Therefore, a simulation of a photovoltaic panel was proposed through mathematical equations that were adjusted according to the data of local radiation. The results have presented equations that provide real answers to the user and may assist in the design of these systems, once calculated that the maximum power limit ensures a supply of energy generated. This real sizing helps establishing the possible applications of solar energy to the rural producer and informing the real possibilities of generating electricity from the sun.
