Entorno virtual-real de la I¡información y formación técnica

While considering distance education as one of several means of access to education in asynchronous mode. We analyze the importance that the project has in this type of information, as well as the development of virtual education in the world. We consider field work, that makes it possible to formulate a series of final considerations, as concerning the role that information and communication technologies (ICT) plays, and the acceptance that it has, in the development of virtual education. The education scope cannot remain indifferent to the impact of new technologies and the knowledge society development. This assessment is supported the need to generate and develop appropriate documentation to the environment, but also, these are suitable for training, education and qualitative and quantitative improvement of teaching and learning processes. For this, we have given cause for, a tool could be useful to create a more educational documentation for students, but also, these are easily for teachers. So, the teacher is the knowledge provider inside and outside of the school

Comportamiento mecánico en función de la temperatura de aleaciones wolfranio-vanadio

Libro de proceedings de: XI Congreso Nacional de Materiales, Zaragoza, 23 junio 2010En esta investigación se evalúa el comportamiento mecánico del wolframio puro y de dos de sus aleaciones con contenidos de 2% y 4% de vanadio, fabricadas mediante prensado isostático en caliente (HIP). La caracterización mecánica se ha realizado mediante ensayos de flexión en tres puntos en atmósfera oxidante a distintas temperaturas comprendidas entre temperatura ambiente y 1000 ºC. Adicionalmente, se han realizado ensayos en inmersión en nitrógeno líquido para los de -197 ºC. Estos últimos valores pueden servir para una determinación más precisa de la temperatura la transición dúctil-frágil en éstos materiales, y de su posible comportamiento plástico o frágil a temperatura ambiente. Mediante estos ensayos ha sido posible obtener la tenacidad de fractura, la resistencia mecánica, el límite elástico y el módulo de elasticidad en función de la temperatura. Así mismo, se ha determinado la densidad y la dureza Vickers para dos cargas distintas, lo que permitido determinar la influencia de este parámetro en la medida realizada. Adicionalmente, se han examinado mediante microscopia electrónica de barrido las superficies de fractura. De esta forma ha sido posible determinar el modo de rotura y analizar la relación de las propiedades mecánicas macroscópicas con los micromecanismos de fallo involucrados.Este trabajo ha sido financiado por EFDA/CIEMAT WP08-09-MAT-WWALLOY, Ministerio de Ciencia e Innovación, MAT2007-29278-E, BIA2004-04835, y MAT2009- 13979-C03-02, y Comunidad de Madrid, SS2009/MAT-1585 y S2009/ENE-1679Publicad

The Children\u27s Community Center

We are the Children’s Community Center, a NGO thats wants to provide an emergency response to the new surge of Rohingya refugee children. We want to relieve the daily mental traumas of the refugee camps through the collaborative interaction of the different children within the camps. This center will also give parents the space to focus on their own healing without the preoccupation of childcare. Nexus Maximus IV The Challenge: Innovation for Refugees and Displaced Populations One of the great challenges of our time is how to help refugees and displaced populations, and how to prevent the causes in the first place. Every minute, 24 people around the world are forced to flee their homes. That’s 34,000 people a day who leave everything behind in the hope of finding safety and a better tomorrow. The impact of war, political, racial and religious conflict, and environmental crises of famine and climate change, have caused great suffering and there is a great opportunity to do better. The issues these populations and the countries who receive them face are diverse and complex. They include public health, housing/built environment, cultural integration, public safety, employment/economic and more. How can innovation address these challenges? How do we create the social systems and products to support a healthy, safe and integrated program for refugees? How do we address the physical, emotional, and social needs of refugees to restore hope and opportunity? The solutions may be as far ranging as the challenges, exploring the acute needs during a crisis, as well as the chronic needs of the permanently displaced; looking at immigration and adjustments to new cultures. We encourage participants to draw upon all disciplines, from health professions to architecture, engineering to design, ethics, communication and every way of thinking we have, to find better ways to innovate on physical solutions, processes, policies, systems, and more.

Euschistus heros mass rearing technique for the multiplication of Telenomus podisi

O objetivo deste trabalho foi melhorar a técnica de criação massal de Euschistus heros em laboratório. Ninfas e adultos foram criados nas densidades de 100, 200, 300 e 400 ovos por placa de Petri (9 cm diâmetro), e 50, 100, 150 e 200 casais por gaiola de criação (900 mL), respectivamente. Foram determinadas a taxa de sobrevivência dos estágios imaturos e a sobrevivência e reprodução de adultos. A sobrevivência das ninfas até o estágio de adulto foi maior (89%) quando criadas em densidade de 100 ovos por placa de Petri. A sobrevivência dos adultos foi independente da densidade, e 100 casais por gaiola de criação foi a melhor densidade encontrada para melhorar a qualidade dos insetos. Nessas condições, a fecundidade das fêmeas foi de 160,8±9,28 ovos por fêmea, e um total de 8.950±456 ovos por gaiola por mês foi produzido. A densidade de 200 casais por gaiola apresentou efeito negativo sobre a reprodução, que decresceu 65%. Com esta técnica, uma colônia de 35 gaiolas com 100 casais por gaiola produz cerca de 313,3 mil ovos por mês, quantidade suficiente para liberar o parasitóide de ovos Telenomus podisi em 35 ha de plantio de soja.The objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively. Survival rate of immature stages and survivorship and reproduction of adults were determinated. Survivorship of nymph to adult was the highest (89%) at density 100 eggs per dish. Adult survivorship was independent of density, and 100 couples per cage were the best to improve quality of the produced progeny. In these conditions, fecundity was 160.8±9.28 eggs per female, and a total of 8,950±456 eggs per cage per month was produced. Two hundred couples per cage showed a negative effect on reproduction, which decreased to 65%. With this technique, a colony of 35 cages with 100 couples per cage yields about 313.3 thousands eggs per month, which is enough to supply the egg parasitoid Telenomus podisi to colonize about 35 ha of soybean field

Graph theory analysis of resting-state functional magnetic resonance imaging in essential tremor.

Essential tremor (ET) is a neurological disease with both motor and non-motor manifestations; however, little is known about its underlying brain basis. Furthermore, the overall organization of the brain network in ET remains largely unexplored. We investigated the topological properties of brain functional network, derived from resting-state functional MRI data, in 23 ET patients vs. 23 healthy controls. Graph theory analysis was used to assess the functional network organization. At the global level, the functional network of ET patients was characterized by lower small-world values than healthy controls - less clustered functionality of the brain. At the regional level, compared with the healthy controls, ET patients showed significantly higher values of global efficiency, cost and degree, and a shorter average path length in the left inferior frontal gyrus (pars opercularis), right inferior temporal gyrus (posterior division and temporo-occipital part), right inferior lateral occipital cortex, left paracingulate, bilateral precuneus bilaterally, left lingual gyrus, right hippocampus, left amygdala, nucleus accumbens bilaterally, and left middle temporal gyrus. In addition, ET patients showed significant higher local efficiency and clustering coefficient values in the frontal medial cortex bilaterally, subcallosal cortex, posterior cingulate, parahippocampal gyri bilaterally (posterior division), right lingual gyrus, right cerebellar flocculus, right postcentral gyrus, right inferior semilunar lobule of cerebellum and culmen of vermis. In conclusion, the efficiency of the overall brain functional network in ET is disrupted. Further, our results support the concept that ET is a disorder that disrupts widespread brain regions, including those outside of the brain regions responsible for tremor.pre-print1168 K

Microbial Contamination in Milk Quality and Health Risk of the Consumers of Raw Milk and Dairy Products

d market. Milk quality and food safety concern in the consumers’ health and nutrition in public health surveillance prevent food-borne diseases, food poisoning, and zoonosis risk by raw milk and fresh dairy products. The aim of this work is focused on milk microbial contamination and its impacts on milk production and dairy industry with their implications in milk product quality, food-borne diseases from raw milk, and unpasteurized milk by food-borne pathogen microbial contamination and milk and dairy product spoilage. The microbial milk contamination source comes from herd hygiene and health status, mastitis prevalence, production environment, and milking parlor and milk conserving practices in dairy farm. Moreover, these facts are implicated in milk quality and milk spoilage and unsafe dairy products. The milk production system and the dairy plant operations keep track in pasteurized milk and fresh dairy products reviewing the traceability in field situational diagnosis report
