Owing to its ability to reduce the toxicity of environmental pollutants that are risk factors for diabetes and obesity, the use of probiotic bacteria might aid the treatment of these diseases. To determine the effects of chronic exposure to low-dose malathion on weight and glucose levels in mice, as well as to evaluate the protective role of a probiotic supplement. Weight and serum glucose levels of four groups of mice (control, malathion-exposed [10 ppm], probiotics and malathion + probiotics) were determined every 10 days for 180 days. Malathion administration induced an increase in weight and glucose levels in the malathion group mice in comparison with the other groups. Consumption of food contaminated with malathion residues increases glucose levels and favors weight gain, while consumption of probiotics reduces the effects generated by residues in food.

Network automation is the current challenge that operators face to accelerate end-to-end service delivery and improve network operations in the context of rapidly growing capacity needs. Optical networks have long been built using vendors’ turn-key solutions, resulting in complexity for the operator to automate its multi-vendor networks in a consistent way. Questioning the vendors’ lock-in in disaggregating the optical transmission systems (i.e., splitting the system into parts, where each part can be provided by a different vendor) provides advantages (e.g., cost) but also additional complexity. Openness and standardization appear as key for these multi-vendor scenarios. The path is not easy, but it is not a matter of choice: opening and interoperability are obligations that we face because of the need for automation. The journey that we detail in this paper is the one that we think will be sustainable from our side. The opposite, i.e., continue building vendors’ silos and staking per-vendor specialized applications, is not sustainable. We propose a step-by-step approach, starting with the non-disaggregated situation, followed by partial and full disaggregation architectures to the last evolution towards data centric networking. We present and discuss implementations that Orange has been contributing to and identify some gaps the industry should address. We show that current works in the communities of open source, open initiatives, and standardization bodies are addressing all these steps, and in this respect can accelerate the deployment of automation solutions in current and future optical transport networks.

LAGO, the Latin American Giant Observatory, is an extended cosmic ray observatory, consisting of a wide network of water Cherenkov detectors located in 10 countries. With different altitudes and geomagnetic rigidity cutoffs, their geographic distribution, combined with the new electronics for control, atmospheric sensing and data acquisition, allows the realisation of diverse astrophysics studies at a regional scale. It is an observatory designed, built and operated by the LAGO Collaboration, a non-centralised alliance of 30 institutions from 11 countries. While LAGO has access to different computational frameworks, it lacks standardised computational mechanisms to fully grasp its cooperative approach. The European Commission is fostering initiatives aligned to LAGO objectives, especially to enable Open Science and its long-term sustainability. This work introduces the adaptation of LAGO to this paradigm within the EOSC-Synergy project, focusing on the simulations of the expected astrophysical signatures at detectors deployed at the LAGO sites around the World.

Fashion products are goods purchased based on cultural and psychological values derived from a brand image as well as on the physical value of the product itself. Management of brand image has been one of the most important marketing strategies in the fashion industry. In this research, three best-selling young casual brands were tested with 200 male and female subjects to compare brand image, logo image, and advertisement image. The objective of the research were as follows: 1) to explore the effect of advertisement on the purchase of young casual wear and brand image management status through advertisements of domestic brands, and 2) to investigate differences in consumer perception on brand logo image and advertisement image. The results showed that most of young casual brands are depending much on star marketing rather than developing differentiated brand image through advertisements as indicated in brand image management status. Failure in development of differentiated and consistent brand image is a barrier to the long-term and continuous advancement of young casual brands. Therefore, more efforts should be made for the reinforcement of brand image for the consistent growth of domestic young casual brands.

\n Este trabalho aborda a detecção da condição de ilhamento e de seus impactos em redes de distribuição e em gerações distribuídas que empregam conversores CC-CA. Na literatura são encontradas dois grupos de técnicas para este tipo de aplicação. As técnicas passivas, que identificam a condição de ilhamento através do ajuste dos limites de variação dos relés de proteção, e as técnicas ativas, que inserem um sinal de realimentação positiva de forma a tornar o sistema instável no momento da desconexão. As técnicas ativas, por apresentarem um menor tempo de detecção e simples implementação em hardware, são preferencialmente utilizadas, apesar da injeção de distúrbios no sistema de controle da geração distribuída. O estado-da-arte em termos de detecção de ilhamento consiste em desenvolver uma técnica que possua alta capacidade de detecção, porém sem injeção de distúrbios no sistema de geração distribuída quando conectado à rede de distribuição. Neste trabalho, são abordadas duas formas para a redução da injeção de distúrbios e do tempo de detecção. Em uma primeira abordagem é proposto um projeto ótimo para o algoritmo de sincronização PLL (phase-locked loop), o qual permite a redução do ganho de realimentação positiva para técnicas em frequência e, consequentemente, a redução da injeção de distúrbios. Em uma segunda abordagem é utilizada a metodologia fuzzy de forma a garantir a detecção da condição de ilhamento sem nenhuma injeção de distúrbios no sistema de controle. Resultados de simulação e experimentais, obtidos por meio de uma bancada experimental controlada por DSP, são apresentados para validar as propostas presentes nesta dissertação\n

Recent years have witnessed the convergence of the traditional telco world to the IT and media worlds. With the migration to all-IP NGN networks to deliver next-generation telecommunication services, the service production infrastructure will undergo fundamental changes. Today?s communication service provider (CSP) architectures are based on separate stovepipes for fixed, mobile, and data services. In the pre-NGN era the business logic was mainly integrated in the software controlled digital switches.

Peer selection for query routing is a core task in peer-to-peer networks. Unstructured peer-to-peer systems (like Gnutella) ignore this problem, leading to an abundance of network traffic. Structured peer-to-peer systems (like Chord) enforce a particular, global way of distributing data among the peers in order to solve this problem, but then encounter problems of network volatility and conflicts with the autonomy of the peer data management. In this paper, we propose a new mechanism, INGA, which is based on the observation that query routing in social networks is made possible by locally available knowledge about the expertise of neighbors and a semantics-based peer selection function. We validate INGA by simulation experiments with different data sets. We compare INGA with competing peer selection mechanisms on resulting parameters like recall, message gain or number of messages produced.

We report on the introduction of a Architecture at Deutsche Telekom. Starting from the request a) to consolidate existing supportive ICT-Systems in training and education, b) to get a comprehensive overview of the company's training activities and c) to save money also within training and education, a project was set up in order to introduce a company-wide Learning Architecture.
