Special Issue of ICETETS 2014 -Held on 24-25 February

Abstract The survey conducted recently reckons that by the year 2010 more than 10 billion wireless sensors have been deployed for various applications, as diverse as environmental monitoring, agricultural monitoring, machine health monitoring, surveillance, and medical monitoring. These networks connect the physical world with the digital world and provide us a better understanding of controlling our surroundings. Advances in wireless sensor network technology has lead to the availability of small and less cost sensor nodes which have the capability of sensing different types of physical and earthly conditions, data processing and wireless communications. Various sensing capabilities results in profusion of application area. Many routing, power management, and data dissemination protocols have been specifically designed for WSNs. We would like to highlight the strengths and performance issues of each routing technique and conclude the paper by bringing to your notice the possible future research areas

Enhancing the Security And Authenticity of Insurance Claims Using Blockchain Technology

"Blockchain technology allows digital information to be distributed but not copied, by creating the backbone to a new type of internet". Firstly, it was used for the Bitcoin, digital currency, now the technological community is finding more challenging uses for the blockchain technology. The objective of this poster is to make use of blockchain technology for insurance industries by analyzing its challenges and how blockchain technology can overcome them

Membrane transporters in the bioproduction of organic acids: state of the art and future perspectives for industrial applications

Organic acids such as monocarboxylic acids, dicarboxylic acids or even more complex molecules such as sugar acids, have displayed great applicability in the industry as these compounds are used as platform chemicals for polymer, food, agricultural and pharmaceutical sectors. Chemical synthesis of these compounds from petroleum derivatives is currently their major source of production. However, increasing environmental concerns have prompted the production of organic acids by microorganisms. The current trend is the exploitation of industrial biowastes to sustain microbial cell growth and valorize biomass conversion into organic acids. One of the major bottlenecks for the efficient and cost-effective bioproduction is the export of organic acids through the microbial plasma membrane. Membrane transporter proteins are crucial elements for the optimization of substrate import and final product export. Several transporters have been expressed in organic acid-producing species, resulting in increased final product titers in the extracellular medium and higher productivity levels. In this review, the state of the art of plasma membrane transport of organic acids is presented, along with the implications for industrial biotechnology.This work was supported by the strategic programme UID/BIA/04050/2019 funded by Portuguese fundsthrough the FCT I.P., and the projects: PTDC/BIAMIC/5184/2014, funded by national funds through the Fundacao para a Ciencia e Tecnologia (FCT) I.P. and by the European Regional Development Fund (ERDF) through the COMPETE 2020-Programa Operacional Competitividade e Internacionalizacao (POCI), and EcoAgriFood: Innovative green products and processes to promote AgriFood BioEconomy (operacao NORTE-01-0145-FEDER-000009), supported by Norte Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF).

Cecal Dieulafoy lesion is a rare cause of lower gastrointestinal bleeding: A case report

Dieulafoy lesions are a rare but life-threatening cause of gastrointestinal bleeding. Colonic Dieulafoy lesions are exceptionally rare, comprising only 2% of these lesions. We present a case of cecal Dieulafoy lesion as an unusual cause of lower gastrointestinal bleeding—along with hemoptysis. An 81-year-old male with pulmonary hypertension presented with a one-day history of hematochezia. He subsequently developed new small-volume hemoptysis/hematemesis with increasing oxygen requirements. Bronchoscopy revealed old blood in the left lower lobe, with no active bleeding. The hemoptysis was attributed to severe pulmonary hypertension. Colonoscopy revealed a 2-mm cecal Dieulafoy lesion with spurting bleeding, which was clipped. We report a rare case of cecal Dieulafoy lesion with only 13 other published cases. Our case was complicated by hemoptysis creating an interesting diagnostic dilemma. In patients bleeding from both oral and anal orifices, a brisk upper gastrointestinal bleed—as well as independent causes involving the gastrointestinal and respiratory tracts—should be considered
