The importance to update the guidelines for the use of genetic testing in noncancer patients in Brazil

The Brazilian National Regulatory Agency for Private Health Insurance and Plans has recently published a technical note defining the criteria for the coverage of genetic testing to diagnose hereditary cancer. In this study we show the case of a patient with a breast lesion and an extensive history of cancer referred to a private service of genetic counseling. The patient met both criteria for hereditary breast and colorectal cancer syndrome screening. Her private insurance denied coverage for genetic testing because she lacks current or previous cancer diagnosis. After she appealed by lawsuit, the court was favorable and the test was performed using next-generation sequencing. A deletion of MLH1 exon 8 was found. We highlight the importance to offer genetic testing using multigene analysis for noncancer patients.

Reshaping higher education systems in the MENA region: the contribution of remote and virtual labs

Learning is not only happening in school or university; it is also an important aspect of the daily life that allows students to remain in their biological and physical environment helping to reshape it, by applying what they have learnt. Today, the higher education sector is a part of important strategies used by countries in order to foster their development. Despite its geographical location, i.e. its closeness to Europe and Asia, the MENA (Middle East and North Africa) region still needs an integrated strategy for the advancement, reform, and update of its higher educational landscape. Although some solutions have been experimented in the region in the field of higher education, they have not been able to raise the quality of education to the level comparable that observed in developed countries. In other words, many MENA higher education systems are facing problems, for which solution ought to be sought. We analyse the situation of higher education systems in the MENA countries and the factors that affect the delay in achieving the level of education existing in other world regions, e.g. Europe, especially in the higher education sector. During the discussion, the impact of new technology-enhanced tools, such as remote laboratories, in the process of development and consolidation of MENA universities, is particularly stressed.

Evaluation of the influence of testing parameters on the melt flow index of thermoplastics

The main goals of the present work are the evaluation of the influence of several variables and test parameters on the melt flow index (MFI) of thermoplastics, and the determination of the uncertainty associated with the measurements. To evaluate the influence of test parameters on the measurement of MFI the design of experiments (DOE) approach has been used. The uncertainty has been calculated using a "bottom-up" approach given in the "Guide to the Expression of the Uncertainty of Measurement" (GUM). Since an analytical expression relating the output response (MFI) with input parameters does not exist, it has been necessary to build mathematical models by adjusting the experimental observations of the response variable in accordance with each input parameter. Subsequently, the determination of the uncertainty associated with the measurement of MFI has been performed by applying the law of propagation of uncertainty to the values of uncertainty of the input parameters. Finally, the activation energy (Ea) of the melt flow at around 200 degrees C and the respective uncertainty have also been determined.

Towards high-available and energy-efficient virtual computing environments in the cloud

Empowered by virtualisation technology, cloud infrastructures enable the construction of flexi- ble and elastic computing environments, providing an opportunity for energy and resource cost optimisation while enhancing system availability and achieving high performance. A crucial re- quirement for effective consolidation is the ability to efficiently utilise system resources for high- availability computing and energy-efficiency optimisation to reduce operational costs and carbon footprints in the environment. Additionally, failures in highly networked computing systems can negatively impact system performance substantially, prohibiting the system from achieving its initial objectives. In this paper, we propose algorithms to dynamically construct and readjust vir- tual clusters to enable the execution of users’ jobs. Allied with an energy optimising mechanism to detect and mitigate energy inefficiencies, our decision-making algorithms leverage virtuali- sation tools to provide proactive fault-tolerance and energy-efficiency to virtual clusters. We conducted simulations by injecting random synthetic jobs and jobs using the latest version of the Google cloud tracelogs. The results indicate that our strategy improves the work per Joule ratio by approximately 12.9% and the working efficiency by almost 15.9% compared with other state-of-the-art algorithms.

Lugar, Espaço e Geografia - Do Real ao Virtual na Sociedade do Conhecimento

As alterações sociais, culturais, tecnológicas ou puramente virtuais a que se assiste são indiscutíveis e, porventura, irreversíveis. O ritmo da evolução tecnológica não permite pausas. A crescente densidade das redes e a velocidade dos fluxos de informação fazem aumentar a complexidade da análise, contrastando com uma diminuição dos tempos de resposta. Observa-se uma dinâmica cada vez mais acentuada no processo de transição entre a informação e o conhecimento, acelerando os inputs que influenciam ou dominam as práticas sociais, políticas e simbólicas da vida. Este artigo analisa conceitos como “informação” e “conhecimento” e outros, mais geográficos, como “lugar” e “espaço”; e de que forma pode a sua dinâmica influenciar o território, que deixa de ser (apenas) real para passar a ser, também, virtual. A Sociedade do Conhecimento surge a partir da Sociedade da Informação, num contexto evolucional da cadeia de valor “dado-informação-conhecimento-sabedoria” e onde o elevado potencial tecnológico extravasa as noções tradicionais da Geografia. Para ajudar a compreender as mutações observadas no território, explicando as suas causas e consequências surge a Geografia da Sociedade do Conhecimento, um ramo da Geografia vocacionado para a análise do desenvolvimento sócio-económico da sociedade moderna.

Geografia Virtual – A Representação do(s) Lugar(es) Físico(s) no Espaço da Internet

A Geografia tem a ver com o lugar, com a localização, com a sociedade, com o ambiente, com o espaço e com a região. Uma vez que no ciberespaço algumas destas variáveis são difíceis de definir, o campo de pesquisa da geografia virtual terá que ser aprofundado,. Este novo domínio da análise geográfica apresenta-se como uma forma de percepcionar a representação do(s) espaço(s) físico(s) no espaço virtual da Internet. Este artigo pretende mostrar um exemplo de um ‘interface’ de cartografia digital, disponível on-line, que pelas suas características inovadoras representa ‘o estado da arte’ na análise dos espaços reais ou geográficos, no espaço virtual da Internet. A sua escolha prende-se com o facto desta ferramenta utilizar conceitos e fundamentos da Geografia, aos quais foram aplicadas as modernas tecnologias de programação para ambientes da www, como as linguagens VRML, XML, Java e Flash.

Distributed Generation and Demand Response Dispatch for a Virtual Power Player Energy and Reserve Provision

Recent changes in the operation and planning of power systems have been motivated by the introduction of Distributed Generation (DG) and Demand Response (DR) in the competitive electricity markets' environment, with deep concerns at the efficiency level. In this context, grid operators, market operators, utilities and consumers must adopt strategies and methods to take full advantage of demand response and distributed generation. This requires that all the involved players consider all the market opportunities, as the case of energy and reserve components of electricity markets. The present paper proposes a methodology which considers the joint dispatch of demand response and distributed generation in the context of a distribution network operated by a virtual power player. The resources' participation can be performed in both energy and reserve contexts. This methodology contemplates the probability of actually using the reserve and the distribution network constraints. Its application is illustrated in this paper using a 32-bus distribution network with 66 DG units and 218 consumers classified into 6 types of consumers.
