Telemedicine and mobile health with integrative medicine in developing countries

2014

International audience; African Home-based Care (AHC) and African Traditional Medicine (ATM) provide a number of self-sustainable primary health care workers in a rural region with the appreciation of ancestral knowledge and its contextual management. Even though most urban residents are able to afford and use conventional medicine to large extent, the implementations of modern medicine in rural areas and in poor peri-urban areas are limited. Our proposal is on how telemedicine solutions could enhance AHC and ATM practices and facilitate simultaneous delivery of both modern and traditional healthcare with evident added value to the recipients. This is indeed a fresh angle, as information an…

Approaches used to care for carious primary molars among pediatric dentists and general dental practitioners in Saudi Arabia

2018

Background The aim of this cross sectional study was (1) to identify and compare the approaches which are used to care for carious primary molars between pediatric dentists (PDs) and general dental practitioners (GDPs) in Saudi Arabia and (2) to evaluate the knowledge level of the most appropriate treatment decisions for both groups with regard to caries in primary molars and its relation with demographic variables. Material and Methods A random sample of 600 GDPs and all registered PDs (n = 100) in the Saudi dental society in 2016 were emailed a two part questionnaire; the first part included questions about demographic data and the second part investigated knowledge of the participants of…

Diffusion processes and growth on aluminum cluster surfaces

1997

Diffusion processes of adatoms on icosahedral and Wulff polyhedral aluminum cluster surfaces have been studied by molecular dynamics simulations using the effective medium theory. Activation energies of diffusion mechanisms along {111} and {100} facets and from one facet to another, including different hopping and exchange processes as well as more exotic events, have been calculated. Exchange diffusion of an adatom by a chain mechanism through a {100} facet between two {111} facets and hopping diffusion across the edge between two {111} facets via a pull of another adatom on the neighbour facet are shown to play an important role. Adatoms on {111} facets are mobile already at very low temp…

Ser uno mismo. Repensando la autonomía y la responsabilidad como coordenadas de la educación actual

2012

One of the main goals of education in the 21st Century is developing students’ autonomy and responsibility. The first is to guarantee the shaping of each individual’s identity, which at the same time entails a pledge to one’s self, to others and to the surrounding reality. The second is in response to our ability to make commitments. To this end we must first immerse ourselves in the concepts of individuality and freedom, which are at the heart of the subject’s awakening and the development of his or her identity. Second, we must outline to all people their rights and duties which will act as permanent reference points that are valid for any situation of interaction. This will finally allow…

On Angels and Demons. Analysis of a sequence in the iconographic programme of the encyclopedic moralization of fin´amors in Matfré Ermengaud´s Brevia…

2017

En el present treball parem esment a 3 il·luminacions del Breviari d’Amor de Matfré Ermengaut que són ben eloqüents –valga la sinestèsia: imatges que són eloqüents— de la vocació d’Ermengaut en pro de la cristianització de la fin’amors. A més, estableixen una mena de seqüència en el concert de diàleg entre història natural, història sagrada i atenció a l’amor, als amadors, a fi i efecte que estableix qui és el receptor concret de l’obra, qui el model a seguir (els àngels) i qui a defugir (el dimoni), i quin és l’àmbit d’actuació del «maligne» : la societat cortés, ecosistema de la fin’amor. This paper analyzes three illuminations of Matfré Ermengaud´s Breviari d´Amor which represent the aut…

Are There Essentially Incomplete Knowledge Representation Systems?

2001

A mathematical model of a knowledge representation system (KR-system) is proposed. Its prototype is the concept of an information system in the sense of Z. Pawlak; however, the model is, in fact, a substantial extension of the latter. In our model, attributes may form an arbitrary category, where morphisms represent built-in functional dependencies, and uncertainty of knowledge is treated in terms of category theory via monads. Several notions of simulation are also considered for such KR-systems. In this general setting, the semiphilosophical problem mentioned in the title, still open, is given a precise meaning.

Multicast access control concept for xDSL-customers

2006

Multicast is a tempting possibility for many broad- band services. It makes possible to deliver one data-stream to several receivers simultaneously. IP-Multicast is based on an open group concept. This means that it is possible for all the users to join the group and thus receive the data. The open concept is also the main reason why multicast has not been taken in wider use. There is two different solution to solve this problem, group access control and multicast data encryption. Group access control mechanisms focuses on restricting the group membership at the users edge device. Traffic encryption scheme relies on end-to-end encryption, so a key management architecture is also needed. We …

Designing disease-resistant crops : from basic knowledge to biotechnology

2020

Ancient records describe how plant diseases were attributed to many causes which included divine power, religious belief, and superstition. Far from these days, we now have detailed knowledge about how plant immunity is executed. Plants employ two types of sensors to perceive and defeat the litany of pathogenic organisms that attack them, whilst microbes deploy a myriad of specialized weapons to suppress immunity and promote infection. This opens a path to exploiting these insights to increase crop resistance. Here we describe novel biotechnological approaches for designing superior disease-resistant crops to fight agricultural losses in the field while reducing chemical inputs, towards a m…

Vertebrate Hedgehog is secreted on two types of extracellular vesicles with different signaling properties

2014

Hedgehog (Hh) is a secreted morphogen that elicits differentiation and patterning in developing tissues. Multiple proposed mechanisms to regulate Hh dispersion includes lipoprotein particles and exosomes. Here we report that vertebrate Sonic Hedgehog (Shh) is secreted on two types of extracellular-vesicles/exosomes, from human cell lines and primary chick notochord cells. Although largely overlapping in size as estimated from electron micrographs, the two exosomal fractions exhibited distinct protein and RNA composition. We have probed the functional properties of these vesicles using cell-based assays of Hh-elicited gene expression. Our results suggest that while both Shh-containing exo-ve…
