Temperature and atmospheric pressure may be considered as predictors for the occurrence of bacillary dysentery in Guangzhou, Southern China

Introduction The control of bacillary dysentery (BD) remains a big challenge for China. Methods Negative binomial multivariable regression was used to study relationships between meteorological variables and the occurrence of BD during the period of 2006-2012. Results Each 1°C rise of temperature corresponded to an increase of 3.60% (95%CI, 3.03% to 4.18%) in the monthly number of BD cases, whereas a 1 hPa rise in atmospheric pressure corresponded to a decrease in the number of BD cases by 2.85% (95%CI = 3.34% to 2.37% decrease). Conclusions Temperature and atmospheric pressure may be considered as predictors for the occurrence of BD in Guangzhou.

Prevalence and genotype distribution of human papillomavirus: implications for cancer screening and vaccination in Henan province, China

Abstract: INTRODUCTION: To provide information for cervical cancer screening and vaccination in Henan province, China, the distribution of human papillomavirus (HPV) was analyzed. METHODS: The HPV genotypes were detected using gene array and flow-through hybridization. RESULTS: Overall, 38.1% (1,536/4,033) of the women were human papillomavirus deoxyribonucleic acid (HPV DNA) positive. The prevalence of high-risk HPV types was 32.4%. HPV 16 was the most prevalent genotype (8.9%), followed by HPV 52 (5.8%) and HPV 58 (4.4%). CONCLUSIONS: The data support close surveillance of women for cervical cancer screening, and HPV prophylactic vaccines including HPV16, HPV 52, and HPV 58 might offer greater protection in this area.

O Golfo da Guiné e a segurança energética dos EUA e da China

O objetivo deste estudo centra-se na análise e na comparação do contributo do petróleo do golfo da Guiné para a segurança energética dos EUA e da China no período 1990-2000, tendo presente a afirmação recente da região africana num quadro de escassez da matéria-prima. Foram elaborados três case studies visando caracterizar as potencialidades e riscos associados à região produtora e analisar o crescente envolvimento dos EUA e da China, através da implementação de políticas públicas conducentes à obtenção dos resultados visados e mediante o reforço da exposição da vertente empresarial. Os resultados obtidos traduziram-se no reforço do abastecimento dos EUA, mantendo uma posição ímpar perante o maior fornecedor regional, a Nigéria, enquanto a China assumiu posição de crescente relevância na região e sedimentou uma relação de grande preponderância face ao outro grande produtor, Angola. A existência de nexos de causalidade entre níveis de segurança energética e o recurso a instrumentos de políticas públicas é um domínio complexo, sendo de referir que o recurso ao economic statecraft pelos EUA, não afigura hipótese fundamentada enquanto fator explicativo das performances alcançadas por este país na região.

Effects of circular myotomy on the healing of esophageal suture anastomosis: an experimental study

For esophageal reconstruction in newborns with esophageal atresia, esophageal reunion with an end-to-end anastomosis is the ideal procedure, although it may result in leaks and strictures due to tension on the suture line, mainly in cases with a wide gap between the ends. Circular myotomy (Livaditis' procedure) is the best method to elongate the proximal esophageal pouch and reduce anastomotic tension. This experimental investigation in dogs was undertaken to attempt to verify that circular myotomy decreases the anastomotic leak rate in newborns with wide gap esophageal atresia, and to analyze whether the technique promotes morphologic changes in the anastomotic scar. A pilot study demonstrated that it is necessary to resect more than 8 cm (40% of the total esophageal length) in order to obtain high leak rates. In the experimental project, such resection was performed in dogs divided into two groups (control group, anastomosis only, and experimental group, anastomosis plus circular myotomy in the proximal esophageal segment). The animals were killed in the 14th postoperative day, submitted to autopsy, and were evaluated as to the presence of leaks and strictures, as well as to the features (macroscopic and microscopic aspects) of the anastomosis. Leak rates were the same in both groups. Morphometric analysis revealed that in animals in the experimental group, the anastomotic scar was thinner than the control animals, and the isolated muscular manchette distal to the site of myotomy was replaced by fibrous tissue. Correspondingly, a decreased number of newly formed small vessels were noted in the experimental animals, compared to control animals. We concluded that circular myotomy does not decrease the incidence of anastomotic leaks, and it also promotes deleterious changes in anastomotic healing.

O Elvis de Macau. Relatos de uma distopia na China

A explosão de Macau nos últimos dez anos deve-se a um conjunto de factores, que este texto procura descrever, propondo uma necessária reflexão. Depois da liberalização do jogo em 2001/2002, o Sands Macau inaugura, em 2004, como o primeiro casino da nova vaga. Em 2005, Macau é Património Mundial da Humanidade pela UNESCO. O Cotai é inicialmente um projecto da administração portuguesa como uma nova cidade para 150 000 habitantes. O Cotai Strip nasce de uma epifania de Sheldon Adelson, chairman da Las Vegas Sands Corporation, em 2003. Em 2007, o Venetian inaugura como “flagship” do Cotai Strip e, em 2011, o Galaxy amplia a dimensão delirante da arquitectura do jogo. No pós-Portugal, a condição de Macau como espaço híbrido, colonizado, transitório, aumenta exponencialmente enquanto “Região Administrativa Especial” da República Popular da China. Macau é hoje uma distopia suave, corporizada nos casinos; uma vida subterrânea que se expressa no skyline.

A comunicação intercultural ao nível da intervenção pedagógica no ensino do português como língua estrangeira a alunos chineses na China

A globalização aproxima os povos: o mundo chinês e o mundo português nunca tiveram uma relação tão estreita como a atual. Apesar de os portugueses terem ido os primeiros ocidentais a entrar na China com a chegada de Jorge Álvares a uma ilha chinesa, em 1513, e os últimos ocidentais a deixar o governo de um território chinês, com a transferência da administração portuguesa de Macau para a China a 20 de dezembro de 1999, nunca haviam sido registados, nos últimos séculos, grandes contatos ou intercâmbios comerciais e culturais entre a China e Portugal e entre o mundo chinês e o mundo lusófono, em comparação com os contatos entre o mundo chinês e outros mundos ocidentais: como o inglês, o francês, o alemão e o espanhol. Os objetivos gerais desta investigação são três: 1 - Reconhecer o papel do desenvolvimento da competência omunicativa intercultural no contexto do ensino-aprendizagem do português como LE na China. 2 - Promover o desenvolvimento da competência comunicativa intercultural dos alunos chineses no processo de aprendizagem da língua portuguesa na China. 3 - Analisar os métodos pedagógicos e de integração curricular para apoiar e desenvolver um ensino mais eficaz do português como LE na China. O desenvolvimento do nosso trabalho articula-se em duas áreas científicas: Ciências da Linguagem e Ciências da Educação. A abordagem metodológica utilizada é o estudo de caso, com recolha de dados primários realizada através de questionários, entrevistas e observação participante em profundidade, que permitiu a confirmação e/ou refutação das hipóteses levantadas, privilegiando a metodologia qualitativa. Os resultados permitem estabelecer uma relação significativa, do ponto de vista pedagógico, entre a comunicação intercultural na educação e as práticas pedagógicas desenvolvidas no ensino do português como língua estrangeira na China. Contudo e de acordo com a nossa pesquisa, o maior problema que impede as práticas pedagógicas para desenvolver as competências comunicativas no ensino, é a falta de materiais didáticos com estrutura para elaborar um programa de atividades coerentes e complementares nas aulas.

Context costs and comparative advantages in the telecommunications sector in Portugal and China

This Work Project aims to discuss the Context Costs and Comparative Advantages of the Telecommunications sector both in Portugal and China. The work was built mostly on primary research by interviews with relevant people (business persons, University Professors and Agencies directors), and by economic data publicly available. A list of context costs and comparative advantages was drawn for each country and possible resolutions suggestions were made in the end. The context costs depend heavily on the economic situation of the countries and it should be taken into account when assessing the degree of magnitude of each cost of context. The competitive advantages of each country were drawn in comparison with one another. Some key results stand out: firstly, Portugal’s costs of context depend mainly on governmental decisions, uncertainties and instability and China’s cost of context depend primarily on cultural norms, mainly the Guanxi; second, the telecommunications sector shares most of its context costs and advantages with other sectors; third, China as an economic power could use the telecommunications sector as a way to further develop and boost its economy.

Portuguese footwear

This case study deals with the reasons why the Portuguese Footwear Cluster evolved from a small industry focused on the Portuguese internal market into a high-tech industry capable of designing and producing some of the best and most expensive shoes in the world. It went from using the low labor costs of an under-developed economy to produce long series of shoes for pre-designated brands in Northern Europe to having the ability to produce some of the highest quality shoes in the world, in small orders, designed and delivered in record timing, while offering a service of excellence. In 1960, when Portugal became a founding member of EFTA, the footwear industry in Portugal was globally irrelevant, producing low quality shoes directed to the puny internal market and its African colonies. The new free trade zone with economies much more developed that itself, led to the transfer of the labor-intensive, low skilled manufacture from the UK and Scandinavian countries to Portugal. Mostly through joint ventures, the industry was able to mechanize itself so it could produce shoes in long series at low prices. It grew based on that model up until the 1990s, when the emergence of the Asian countries meant either a different strategy or extinction. Taking advantage of a clarified leadership of its trade association, it used the European funds made available to it during the 1990s, to modernize its factory floors, so it could become more nimble and flexible, expand its design capabilities and dramatically change its image abroad. The role of the trade association, APICCAPS, was instrumental throughout the process going well beyond what came to be expected of trade associations. It used its privileged position to provide understanding regarding the current situation and competitive landscape, alerting for changes ahead and at the same time providing a strategic vision on how to deal with the challenges. Moreover, it helped companies get the resources they needed by creating a research center in collaboration with a University, by creating a process that allowed companies to learn from each other via the show casing of projects sponsored by the association or by helping industrials traveling to locations where new customers could be found. The case study provides insight on how the trade association leadership, which has no formal authority over its members, was able to guide and motivate an industry through a consistent positive approach. That approach focused on the solutions, on the opportunities and on the success stories of companies in the cluster rather than on what was wrong or needed to be addressed. Based on this case, one could use the leadership role of the trade association to discuss and change leaders’ roles and styles in other sectors or even companies.

Transfer zone of prestressed CFRP reinforcement applied according to NSM technique for strengthening of RC structures

This study presents an experimental program to assess the tensile strain distribution along prestressed carbon fiber reinforced polymer (CFRP) reinforcement flexurally applied on the tensile surface of RC beams according to near surface mounted (NSM) technique. Moreover, the current study aims to propose an analytical formulation, with a design framework, for the prediction of distribution of CFRP tensile strain and bond shear stress and, additionally, the prestress transfer length. After demonstration the good predictive performance of the proposed analytical approach, parametric studies were carried out to analytically evaluate the influence of the main material properties, and CFRP and groove cross section on the distribution of the CFRP tensile strain and bond shear stress, and on the prestress transfer length. The proposed analytical approach can also predict the evolution of the prestress transfer length during the curing time of the adhesive by considering the variation of its elasticity modulus during this period.

Microphysical evidence of the transition between predominant convective/stratiform rainfall associated with the intraseasonal oscillation in the Southwest Amazon

The distinction between convective and stratiform precipitation profiles around various precipitating systems existent in tropical regions is very important to the global atmospheric circulation, which is extremely sensitive to vertical latent heat distribution. In South America, the convective activity responds to the Intraseasonal Oscillation (IOS). This paper analyzes a disdrometer and a radar profiler data, installed in the Ji-Paraná airport, RO, Brazil, for the field experiment WETAMC/LBA & TRMM/LBA, during January and February of 1999. The microphysical analysis of wind regimes associated with IOS showed a large difference in type, size and microphysical processes of hydrometeor growth in each wind regime: easterly regimes had more turbulence and consequently convective precipitation formation, and westerly regimes had a more stratiform precipitation formation.
