Method and device for live-streaming with opportunistic mobile edge cloud offloading

A novel, pervasive approach to disseminating live streaming content combines secure distributed systems, WiFi multicast, erasure coding, source coding and opportunistic offloading using hyperlocal mobile edge clouds. The solution disclosed to the technical problem of disseminating live streaming content without requiring a substantial equipment, planning and deployment of appropriate network infrastructure points offers an 11 fold reduction on the infrastructural WiFi bandwidth usage without having to modify any existing software or firmware stacks while ensuring stream integrity, authorization and authentication

Тhe economic value of volunteering

Voluntary work is a non-remunerated activity, which is usually performed to satisfy a moral need of the individual as well as to contribute to the collective goal of the society. It usually leads to the creation of goods or services that would in a normal situation require the use of workforce that needs to be paid, meaning it would mean an expense. The goods and services produced through the voluntary work are usually not part of the official measures of production, but volunteers make significant contributions to the economy and society

Optical fiber relative humidity sensor based on a FBG with a di-ureasil coating

In this work we proposed a relative humidity (RH) sensor based on a Bragg grating written in an optical fiber, associated with a coating of organo-silica hybrid material prepared by the sol-gel method. The organo-silica-based coating has a strong adhesion to the optical fiber and its expansion is reversibly affected by the change in the RH values (15.0–95.0%) of the surrounding environment, allowing an increased sensitivity (22.2 pm/%RH) and durability due to the presence of a siliceous-based inorganic component. The developed sensor was tested in a real structure health monitoring essay, in which the RH inside two concrete blocks with different porosity values was measured over 1 year. The results demonstrated the potential of the proposed optical sensor in the monitoring of civil engineering structures

Mineral and volatile composition of agua-mel from Portugal

Agua-mel (honey-water) is a typical honey-based product produced by the Portuguese beekeepers, particularly in southern Portugal. Agua-mel was characterized by mineral content and volatiles contents. Mineral content evaluation was performed based on a random sampling of 14 samples from a total of 16 samples provided by local producers. Mineral content showed that potassium predominated in agua-mel samples (1270-4105 mg/kg). The concentration of aluminium in one sample was tenfold higher (5.8 mg/kg) than in the remaining samples (0.3-0.6 mg/kg). Agua-mel volatiles were isolated by hydrodistillation and analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) from a subset of eight samples. Cluster analysis showed two poorly correlated clusters (S (corr) < 0.3). Cluster I only sample was dominated by trans-beta-ocimene (19 %), gamma-terpinene (15 %) and 2-furfural (9 %). Cluster II that included the remaining seven samples showed two moderately correlated subclusters (S (corr) < 0.5). The six samples with high correlation from subcluster IIa were dominated by 2-furfural (18-41 %) and benzene acetaldehyde (12-39 %). n-Nonadecane (14 %), n-heneicosane and 2-furfural (both 13 %) were the main components of subcluster IIb sample. Although the presence of some volatile compounds can help in the correlation between agua-mel and honey botanical source, the final product varies largely according to the preparation process even for the same producer, in different years. Agua-mel detailed characterization may assist in bringing added value to this typical Portuguese honey-based product

Contribution for new genetic markers of rheumatoid arthritis activity and severity : sequencing of the tumor necrosis factor-alpha gene promoter

This is an open access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly citedThe objective of this study was to assess whether clinical measures of rheumatoid arthritis activity and severity were influenced by tumor necrosis factor-alpha (TNF-alpha) promoter genotype/haplotype markers. Each patient's disease activity was assessed by the disease activity score using 28 joint counts (DAS28) and functional capacity by the Health Assessment Questionnaire (HAQ) score. Systemic manifestations, radiological damage evaluated by the Sharp/van der Heijde (SvdH) score, disease-modifying anti-rheumatic drug use, joint surgeries, and work disability were also assessed. The promoter region of the TNF-alpha gene, between nucleotides -1,318 and +49, was sequenced using an automated platform. Five hundred fifty-four patients were evaluated and genotyped for 10 single-nucleotide polymorphism (SNP) markers, but 5 of these markers were excluded due to failure to fall within Hardy-Weinberg equilibrium or to monomorphism. Patients with more than 10 years of disease duration (DD) presented significant associations between the -857 SNP and systemic manifestations, as well as joint surgeries. Associations were also found between the -308 SNP and work disability in patients with more than 2 years of DD and radiological damage in patients with less than 10 years of DD. A borderline effect was found between the -238 SNP and HAQ score and radiological damage in patients with 2 to 10 years of DD. An association was also found between haplotypes and the SvdH score for those with more than 10 years of DD. An association was found between some TNF-alpha promoter SNPs and systemic manifestations, radiological progression, HAQ score, work disability, and joint surgeries, particularly in some classes of DD and between haplotypes and radiological progression for those with more than 10 years of DD.This work was supported by grant POCTI/SAU-ESP/59111/2004 from Fundação Ciência e Tecnologia.info:eu-repo/semantics/publishedVersio

Guidelines on the management of valvular heart disease: The Task Force on the Management of Valvular Heart Disease of the European Society of Cardiology.

80These guidelines focus on valvular heart disease in adults and adolescents, are oriented towards management, and will not deal with endocarditis and congenital valve diseases in adults and adolescents, since recent guidelines have been produced by the ESC on these topics. Although valvular heart disease is less common in industrialized countries than coronary disease, heart failure, or hypertension, guidelines are needed in this field for several reasons: valvular heart disease is common and often requires intervention; substantial advances have been made in the understanding of its pathophysiology; the patient population has changed with a continuous decline of acute rheumatic fever and an increased incidence of degenerative valvular diseases in industrialized countries. The incidence of endocarditis remains stable and other causes of valve disease are rare. Because of the predominance of degenerative valve disease, the two most frequent valve diseases are now calcific aortic stenosis and mitral regurgitation. Aortic regurgitation and mitral stenosis have become less common. Diagnosis is now dominated by echocardiography, which has become the standard to evaluate valve structure and function. Treatment has not only developed through the continuing progress in prosthetic valve technology, but has also been reoriented by the development of conservative surgical approaches and the introduction of percutaneous interventional techniques.openopenVahanian, A; Baumgartner, ; H, ; Bax, ; J, ; Butchart, ; E, ; Dion, ; R, ; Filippatos, ; G, ; Flachskampf, ; F, ; Hall, ; R, ; Iung, ; B, ; Kasprzak, ; J, ; Nataf, ; P, ; Tornos, ; P, ; Torracca, ; L, ; Wenink, ; A, ; Silvia, ; Priori, G.; Blanc, Jean-Jacques; Andrzej, ; Budaj, ; John, ; Camm, ; Veronica, ; Dean, ; Jaap, ; Deckers, ; Kenneth, ; Dickstein, ; John, ; Lekakis, ; Keith, ; Mcgregor, ; Marco, ; Metra, ; João, ; Morais, ; Ady, ; Osterspey, ; Juan, ; Tamargo, ; Luis, José; Zamorano, ; Annalisa, ; Angelini, ; Manuel, ; Antunes, ; Angel, Miguel; Fernandez, Garcia; Christa, ; Gohlke-Baerwolf, ; Gilbert, ; Habib, ; John, ; Mcmurray, ; Catherine, ; Otto, ; Luc, ; Pierard, ; Josè, ; Pomar, L.; Bernard, ; Prendergast, ; Raphael, ; Rosenhek, ; Sousa, Miguel; Uva, ; Juan, ; Tamargo,Vahanian, A; Baumgartner, ; H, ; Bax, ; J, ; Butchart, ; E, ; Dion, ; R, ; Filippatos, ; G, ; Flachskampf, ; F, ; Hall, ; R, ; Iung, ; B, ; Kasprzak, ; J, ; Nataf, ; P, ; Tornos, ; P, ; Torracca, ; L, ; Wenink, ; A, ; Silvia, ; Priori, G.; Blanc, Jean Jacques; Andrzej, ; Budaj, ; John, ; Camm, ; Veronica, ; Dean, ; Jaap, ; Deckers, ; Kenneth, ; Dickstein, ; John, ; Lekakis, ; Keith, ; Mcgregor, ; Marco, ; Metra, Marco; João, ; Morais, ; Ady, ; Osterspey, ; Juan, ; Tamargo, ; Luis, José; Zamorano, ; Annalisa, ; Angelini, ; Manuel, ; Antunes, ; Angel, Miguel; Fernandez, Garcia; Christa, ; Gohlke, Baerwolf; Gilbert, ; Habib, ; John, ; Mcmurray, ; Catherine, ; Otto, ; Luc, ; Pierard, ; Josè, ; Pomar, L.; Bernard, ; Prendergast, ; Raphael, ; Rosenhek, ; Sousa, Miguel; Uva, ; Juan, ; Tamargo
