Abstract: most regions where cotton is cultivated in brazil present low soil fertility, especially concerning the available phosphorus (p). this study aimed to evaluate the phosphorus split application on irrigated cotton, for reaching a higher phosphate fertilization efficiency, in comparison to the traditional application at sowing. the experiment was conducted in quartzarenic neosol with 22 mg dm-3 of p (medium availability), in the north region of the minas gerais state, brazil. the design used was randomized blocks, in a (4x3) + 3 factorial scheme, with three replications. treatments consisted of p2o5 doses (0 kg ha-1, 30 kg ha-1, 60 kg ha-1, 120 kg ha-1, and 180 kg ha-1) and three split applications (80% and 20%; 60% and 40%; 40% and 60% of the p dose applied respectively at sowing and at 35 days after emergence (dae)), plus the application of 0 kg ha-1, 60 kg ha-1, and 120 kg ha-1 of p2o5 at sowing. the p source was the granulated triple superphosphate, and the p content in the shoots increased according to the doses applied. nutrient contents in the index leaf, except for p, were not influenced by p levels and split applications. the p content in the index leaf and the number of cotton bolls per plant increased with the increment of p doses, but were not affected by the phosphate fertilizer split application. the application of 40% of the p dose at sowing and the remaining amount split at 35 dae decreased the cotton boll yield, with no significant effect for the other split applications.
Utilization of a Blended Learning Approach to Teach Pediatric Resuscitation to Medical Residents  [PDF]
Tricia Swan
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.618201
Abstract: Because of the rarity of the event of pediatric resuscitations, residents are not able to practice and maintain skills that are critical for caring for these patients. Training must be focused on rapid decision making, identification of anatomical structures for intubation, selecting appropriate equipment and sizes for resuscitation procedures, selection of appropriate medications and leading a team in stressful situations. The goal of this study was to evaluate the ability of a blended learning approach to facilitate the acquisition and retention of pediatric resuscitation skills utilizing both simulation technology and on-line education resources.
Impact of Vehicular Array Position on Urban MIMO Channel Characteristics
Christopher C. Squires,Tricia J. Willink
International Journal of Antennas and Propagation , 2011, DOI: 10.1155/2011/675343
Abstract: MIMO channel measurements have been performed in urban environments with antenna arrays positioned on the roof and sides of the measurement vehicle. Analysis of the data shows that the array's position on the vehicle, along with the location and orientation of the vehicle with respect to the transmitter, can have a considerable impact on the channel characteristics observed. Array elements on the vehicle's roof receive the same multipath components, and, therefore, have identically distributed channel responses. However, the characteristics of the multipath components observed at each side of the vehicle can differ significantly. Specifically, shadowing from the vehicle combined with the directionality of the side-mounted array elements affects the angular distribution and powers of the received multipath components, affecting the achievable diversity and channel capacity. This can have significant impact on system performance and should be considered when designing and analyzing vehicular-based signalling techniques. 1. Introduction The capability of multiple-input multiple-output (MIMO) communications systems to exploit multipath diversity to improve system throughput and robustness has been extensively reported on since the early work in [1, 2]. A detailed review can be found in [3]. The signalling strategy used to achieve the desired performance depends on the characteristics of the channel. In particular, the spatial correlation observed depends on the number and angular diversity of the multipath components arriving at the receiver [4]; this changes as mobile terminals move through the physical environment. Thus, to determine the expected performance of a MIMO system, it is necessary to have a good representation of the channel characteristics. Many models of MIMO systems have been developed based on assumptions about the physical structure of the scattering environment, for example, ring models [5] and geometrically based stochastic models [6]. For a summary of these types of models, see [7, Chapter 4]. These models typically assume that the antenna elements at the receiving array have an unobstructed view of the scatterers. For vehicular applications, the antenna elements are close enough to observe the same set of scatterers; hence, the fading statistics and shadowing are the same at all antenna elements. When the array elements are separated by larger spacings, for example, in distributed array systems, the system becomes more robust to variations in shadowing and system capacity can be improved [8]. Although the importance of a well-designed

Abstract:

The purpose of this article is to provide suggestions for two early education policy levers proposed by the Organization for Economic Cooperation and Development (OECD) that can be specifically applied to oral language instructional in the classroom: Policy Lever 2—Designing and implementing curriculum and standards; and Policy Lever 3—Improving qualifications, training and working conditions. First, I describe the efforts the United States has made in terms of oral language instruction, and second I describe a professional development model (the Conversation Compassa?) that trains teachers to use instructional conversations with children age 2-6.

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.41007
Abstract:

Though the high prevalence of biomass fuel use in the developing world is widely known, the use of burning biomass for cooking and heating in the developed world is under-recognized. Combustion materials including coal and wood are also used for heating in some areas of the United States. We conducted a pilot study to assess the feasibility of conducting indoor environmental monitoring in rural Appalachia. We sought to explore the type of biomass being used for home heating and its impact upon indoor air quality in non-heating and heating seasons. Residential indoor air monitoring for particulate matter (PM) and nitrogen dioxide (NO2) was conducted in Lee County, Virginia. Homes had evidence of poor indoor air quality with high concentrations of indoor PM and a large burden of cigarette smoking. Further characterization of indoor combustion material use in this region to determine the health impacts associated with such exposures is warranted.

International Journal of Behavioral Nutrition and Physical Activity , 2004, DOI: 10.1186/1479-5868-1-7
Abstract: Participants (N = 897) were employees from three large worksites who completed self-report inventories containing measures of self-efficacy, outcome expectations, perceptions of the workplace environment (PWES), and physical activity behaviour during both leisure-time and incorporated throughout the workday.Results of both bivariate and multiple regression analyses indicated the global PWES scores had a limited association with leisure-time physical activity (R2adj =.01). Sequential regression analyses supported a weak association between physical activity incorporated in the workplace and PWES (R2adj = .04) and the partial mediation of self-efficacy on the relationship between PWES and workplace physical activity (variance accounted for reduced to R2adj = .02 when self-efficacy was controlled).Overall, the results of the present investigation indicate that self-efficacy acted as a partial mediator of the relationship between perceived environment and workplace physical activity participation. Implications of the findings for physical activity promotion using ecological-based approaches, and future directions for research from this perspective in worksite settings are discussed.Regular physical activity has been established as a mechanism to prevent and treat various chronic illnesses such as heart disease, diabetes, cancer, obesity, osteoporosis and psychological ailments [1-4]. However, the majority of adults in industrialized nations are not physically active enough to accrue health benefits [1,5-7]. In response to this important issue, researchers are investigating effective ways to increase physical activity by furthering our understanding of physical activity behaviour determinants in numerous settings [8].The workplace has been identified by various governments [1,9,10] as a key setting to promote physical activity, due in part to the accessibility of people within their occupation [11]. The majority of Canadian adults are in the workforce and spend half of t

Abstract: O texto aborda o cenário de produ o dos programas de forma o em saúde dirigidos às universidades, retratando prescri es, tens es e rupturas ao buscar alguns caminhos percorridos para reorientar a forma o de profissionais de saúde no Brasil. Retoma iniciativas e propostas nas universidades e nas Conferências Nacionais de Saúde (CNS), destacando a intera o ensino-servi o, as Diretrizes Curriculares Nacionais e a própria concep o de Educa o Permanente em Saúde (EPS). Na sequência, é abordada a Política Nacional de Educa o Permanente em Saúde (PNEPS) que orienta para uma forma o constante de trabalhadores e de futuros profissionais da saúde, através de estratégias e a es coordenadas pela Secretaria de Gest o do Trabalho e Educa o em Saúde (SGTES) criada no início do Governo Lula. O estudo dos movimentos para mudar as gradua es de saúde apresenta a es semelhantes, conquistas e também descontinuidades nesse processo de constitui o da política de forma o em saúde como estratégia de consolida o do SUS. Iniciativas, a es e preocupa es continuam presentes e envolvendo universidades, servi os de saúde, governo e sociedade na tentativa de adaptar, reorientar, reinventar ou colocar em movimento as estratégias de mudan a na forma o em saúde. Abstract This paper addresses the production scenario of health training programs directed to universities portraying requirements, tensions and disruptions to fetch some paths taken to reorient the training of health professionals in Brazil. Initiatives and proposals taken up in universities and National Health Conferences, emphasizing the interaction between teaching and service, the National Curriculum Guidelines and the very conception of Continuing Education in Health. As a result, we have the National Policy on Permanent Education in Health that guides to a constant training of workers and future workers and health professionals through strategic and coordinated action by the Secretary of Labor Management and Health Education created in beginning of the Lula government. The study of movements to change the degrees of health has similar actions, achievements and also discontinuities in the process of incorporation of training in health policy as a strategy of consolidation of the SUS. Initiatives, actions and concerns are still present and involving universities, health services, government and society in trying to adapt, refocus, reinvent or set in motion strategies for change in health education.
