El e-learning como un recurso de desarrollo educativo
Get PDFLas Tecnologías de la Información y de la Comunicación (TIC) tienen un gran potencial en todos los ámbitos de la educación, desde básica a universitaria, incluyendo educación continua y capacitación técnica, ya sea presencial o a distancia. El avance de las TIC es de particular significación para la educación superior, porque ella se caracteriza por ser un sistema en el cual se gestionan exclusivamente datos, informaciones y conocimientos. La educación superior, a través de sus funciones de enseñanza, investigación y extensión, es una compleja organización orientadas al uso, generación y difusión del conocimiento; por ello, es natural pensar que unas tecnologías especialmente destinadas a gestionar el conocimiento y a comunicarlo tengan amplia significación para la educación superior

Get PDFIntroduction: The graphene has received a great attention becauseof its extraordinary characteristics of high carrier mobility, excellent thermal conductivity, high optical transmittance, and superiormechanical strength. Developing a simple methods with the property of producing large quantities of high-quality graphene havebecome essential for electronics, optoelectronics, composite materials, and energy-storage applications. Materials and Methods: Inthis study, the simple one step and efficient method of grindingwas used to produce few-layers graphene nanoflakes from graphite.Different microscopic (TEM, SEM, and AFM) and spectroscopics(XRD, XPS, and Raman) charactrization tools were used to testthe quality of the resultant graphene nanoflakes. Results: The produced nanoflakes showed no traces of oxidation due to the grindingprocess. In addition, the applicability of the obtained nanoflakes aspotential supercapacitor electrodes was investigated. For that purpose, thin films of the few-layer graphene nanoflakes were developed using spray coating technique. In terms of both transparencyand conductivity, the prepared films showed equivalent propertiescompared to those prepared by more complex methods. The electrochemical properties of the prepared electrodes showed highspecific capacitance of 86 F g_1 at 10 A g_1 with excellent stability.The electrodes sustained their original capacity for more than 7000cycles and started reducing to 72 F g-1 after 10000 cycles. Conclussions: The method provides a simple, efficient, versatile, andeco-friendly approach to low-cost mass production of high-qualitygraphene few-layers. The electrochemical stability and flexibility ofthe developed thin films indicated that the films could be used aselectrodes in a wide range of electronic applications
Análisis de las concentraciones de radionúclidos de la atmósfera del aire de Duhok por espectrometría gamma
Get PDFIntroduction: Atmospheric air is directly related to human healthand irreplaceable to human life and thus an influential parameter ofenvironmental science. Radioactive materials in the air may resultin exposure of man every day of our lives by inhalation or ingestion of particulate matter suspended or deposited on vegetation orproducts derived from animals, which has been ubiquitous on earthsince its creation. The main goal of this study is to measure the radioactivity concentration of the natural and artificial radionuclidesof the Duhok air. Materials and Methods: Twenty samples of airfilters were collected from different locations of Duhok City andits surroundings by low volume air samplers pump in the summer/autumn and winter/spring seasons. Air filter samples were preparedand analyzed by a well-type thallium-activated sodium iodide NaI(-TI) detector. Results and Discussion: The average activity concentrations of 214Pb, 214Bi, 212Pb, 228Ac, 40K and 137Cs are4.98±1.20, 4.54±1.27, 9.76±1.17, 10.72±2.35, 211.91±62.19 and1.78±0.61 mBq/m3 respectively of the summer/autumn seasons.Whereas, in the winter/spring seasons are 3.89±1.23, 4.21±1.43,5.05±1.08, ND, 147.49±46.38 and 1.78±0.69 mBq/m3 respectively. Conclusions: The activity concentrations results confirmedseasonal variations for all study locations. Activities of all radionuclides, except an anthropogenic radionuclide 137Cs which remainsabout the same in both seasons, record higher values in summer/autumn season. Moreover, all activities are less than the acceptablelower level. It is clear that the prominent radioelements that affected by atmospheric condition is 40K even though it is less than thereported lower level of the EP
Medición de la concentración de radón (222Rn) y torón (220Rn) en diferentes plantas (vegetales) ubicadas en la ciudad de Sulaimania empleando el detector CR-39
Get PDFIntroduction: Radon is a radioactive gas released from the normaldecay of uranium in rocks and soil depending on local geology. Radioactive decay of uranium through radium produces radon. Materials and Methods: In the present work, seventeen plant (vegetables) samples collected from Sulaimania Governorate. The plants have been analyzed and examined to measure the level of radon (222Rn) and thoron (220Rn) using plastic track detector (CR-39) for evaluation of radon and thoron concentration in this region. Results and Discussion: The results indicated that the higher andlower radon concentration have been found in Halabjay-con, and inSulaimani-center, to be (119.72 Bq.m-3, 3.236 pCi/L), (54.36 Bq.m-3,1.469 pCi/L), respectively, and the higher and lower thoron concentration have been found in Qaladza and in Sulaimani-center, to be (733.66 Bq.m-3, 19.828 pCi/L), (227.33 Bq.m-3, 9.117 pCi/L), respectively. Radiation level compared with the standard level known by the EPA (4 pCi/L) and190 Bqm-3. The concentration of radon in all sample plants is less than international standard level 4(pCi/L)and190 (Bqm-3), therefore the human in safety. The average effective dose equivalent (EDE) of radon from plants determined was (7.2) μSv.y-1 for all the samples. This is lower than the normal value of (1.3) mSv.y-1 given by EPA. Conclusions: This study showed that the contamination in the plant (vegetables) is normal and is not considered a great radial dose for plants and consequently for humans

Get PDFIntrodução: Objetivou-se apreender as representações sociais de profissionais de saúde sobre mulheres que vivem com HIV. Materiais e Métodos: Pesquisa qualitativa e descritiva, com base na Teoria das Representações Sociais. Realizou-se entrevistas com 37 profissionais de serviços de referência em HIV de Belém-Pará, no período de setembro de 2012 a junho 2013. Resultados: O corpus foi submetido à análise pelo software Alceste gerando cinco classes, dentre estas: representações sociais dos profissionais de saúde sobre pessoas que vivem com HIV. Discussão: Os léxicos ilustrativos da classe apontaram a vitimização e a culpabilização da mulher com HIV. Há conteúdos positivos e negativos, dependendo do modo de contaminação. Conclusões: O HIV desperta sentimentos negativos: pena, revolta e culpa. As mulheres são categorizadas e julgadas pelos profissionais, podendo ser vítimas ou culpadas. Há necessidade de políticas de educação permanente aos profissionais de saúde sobre o HIV para que possam desconstruir tais conteúdos.

Exploring the relationship of threshold concepts and Hodges’ model of care from the individual to populations and global health
Get PDFThrough academia, professional disciplines seek – whenever possible – to base their actions on theory rather than fact and historical practices. This serves to improve certainty and place curricula, research, and practice on the best footing in terms of knowledge and quality. This emphasis extends to the workplaces in which professionalised disciplines are learned and practised. In healthcare, great importance is placed upon evidence-based findings to support clinical practice. Although subject to ongoing debate, the quality of research is assessed against a yardstick that culminates in a ‘gold-standard’ of clinical trials and systematic reviews. What healthcare professionals do, should, whenever possible, be based upon evidence, not ritualised practices and missives, such as “I was trained this way” and “This is how we do things here”.How to cite this article: Jones P.

No full textIntroduction: Learning processes necessarilyinvolve the interaction of the leamer and whatserves as a bridge of communication, known asa mediator, it is important to keep in mind thatlearning in some way implies the confluence ofmorphic fields that explain in some way how theyevolve. living systems that co learn, which arereconfigured to potentialize learning routes thatare written on the edges of complexity and orality,uncertainty and patterns of learning, which arerecorded in order structures that also privilegethe permanent reconfiguration of organismsand more than these the cells that form them.Materials and methods: The approach usedin the research process is qualitative, which allowsa holistic perception of reality, in those learningprocesses that each community has been buildingand privileging in the profiles that privilege learning,knowing, a particular and important case is that ofthe Cantoras of Colombia, who over time havepreserved their ancestry and have been writingtheir knowledge in the akásico field. Results anddiscussion: Morphic fields influence resulting ina record of knowledge that is preserved in timeand space, speaking musically: a sublime songof atoms that give quantum leaps when they arereconfigured to register in the neurons themselvesthe knowledge that each being pretends to reachand finds in the long way of learning. In thatmeeting of looks and voices, the article is based.
Conclusions: education requires a profoundtransformation, educational reforms are onlysuperficial strategies that give response orpossibilities of action, but do not open roads tosolve the various problems in which it is immersed.Consider a holistic view, allows to assume amediating role where each individual is building tothe rhythm of their possibilities, their virtues.Introducción: Los procesos de aprendizajes involucrannecesariamente la interacción del que aprende y aquello quesirve como puente de comunicación, conocido como mediador,es importante tener presente que aprender de algún modo implicael hecho que confluyan campos mórficos que explican de algunamanera cómo evolucionan los sistemas vivos que co aprenden,que se reconfiguran para potencializar rutas aprendientes queestán escritas en linderos de la complejidad y de la oralidad,la incertidumbre y en patrones de aprendizajes, que quedanregistrados en estructuras de orden que privilegian tambien lareconfiguración permanente de los organismos y más que estoslas células que los forman. Materiales y métodos: El enfoqueusado en el proceso investigativo es de corte cualitativo, el cualpermite una percepción holística de la realidad, en esos procesosde aprendizaje que cada comunidad ha ido construyendo yprivilegiando en los perfiles que privilegian el aprender, el conocer,un caso particular e importante es el de las Cantoras de Colombia,quienes a través del tiempo han conservado su ancestralidady han ido escribiendo en el campo akásico su conocimiento.Resultados y discusión: Los campos mórficos influyen dandocomo resultado un registro de conocimiento que se preserva enel tiempo y el espacio, hablando musicalmente: un canto sublimede átomos que dan saltos cuánticos cuando se reconfiguran pararegistrar en las neuronas mismas el conocimiento que cada serpretende alcanzar y encuentra en el largo camino del aprender. Enese encuentro de miradas y voces, se fundamenta el artículo.
Conclusiones: la educación requiere una transformaciónprofunda, las reformas educativas son tan solo estrategiassuperficiales que dan respuesta o posibilidades de acciones, perono abren caminos de solución a las diversas problemáticas en laque se encuentra inmersa. Considerar una mirada holística, permiteasumir un papel mediador donde cada individuo va construyendoal ritmo de sus posibilidades, sus virtudes
