Published: May 2017

In Brazil livestock production is facilitated by the extensive areas of pasture available and the possibility of lower production costs compared to other feeding systems. However, native pastures with lack of adequate management can show severe nutritional deficiencies and cultivated pastures, managed erroneously, tend to decay. The use of forage legumes has potential benefits to the pastoral environment, such as incorporation of nitrogen to the system, increase on support capacity and quality of pastures intercropped with grasses, as well as improvement of nutrition to animals and these gains in performance. The use of legumes in ruminants production systems can be made, among other ways, under intercropped grazing with grass species, like supplement or protein sources and even as private supplementation to young animals (creep grazing). The objective of this essay is to discuss the potential use of forage legumes in sheep production, especially the main forms of use and results in animal performance during the past decade.

Authors: Irfan Muhammad , Ahmad Muhammad , Akhtar Sadia , Khan Muhammad , Khan Muhammad
Published: May 2017

The growing demand for niobium pentoxide, based on its use in separation processes, established its prominent significance as a leading candidate in the field of separation science and technology. This study reports the extraction of niobium pentoxide from pyrochlore ore occurring in Sillai Patai, KPK, Pakistan. It is difficult to recover niobium pentoxide from Pakistani ore due to its low concentration. Niobium pentoxide is an important material used in manufacturing industries for different purposes. Most of the commercially employed extraction processes are associated with serious environmental impacts and are not efficient in extracting niobium pentoxide from low concentration pyrochlore. Alkali potash has been used for separation and purification of niobium pentoxide because it is efficient and an environmentally friendly process. The leaching of niobium pentoxide is carried out in a batch reactor using alkali potash as a leachant. Various process parameters, including ore particle size, reaction temperature, reaction time and alkali to ore mass ratio, were examined statistically during the leaching process. It was observed that reaction temperature and ore particle size were more significant compared to other parameters. The maximum percent recovery of niobium pentoxide (95%) was obtained at 280?C in 90 min, while keeping the ore particle size 44 ?m and alkali to ore mass ratio of 7:1.

Published: May 2017

The Republic of Panama plans to expand its power generation park by including renewable energy. Currently, more than half of the Panamanian power generation park is comprised of hydroelectric power and the rest is completed by thermoelectric plants, but other energy sources such as wind, solar, geothermal and peat are available. This paper reviews the current status of the Panamanian power generation park, recent renewable energy developments, the legal framework and incentives in place for these projects, and the renewable energy resources available in the country. Finally, some hypothetical renewable energy projects are evaluated, to initially assess their economic feasibility. It can be concluded from this paper that: 1) hydro power is the only renewable currently in the Panamanian power generation park and comprises most of the future projects, 2) wind power is the other renewable with most potential in Panama, with the second-largest number of projects, 3) solar, geothermal and peat resources are available in Panama but there are no current developments to include them as part of large-scale power generation, 4) initial evaluation of two hypothetical hydroelectric and wind projects shows economic feasibility under the given assumptions; however, the project feasibility is dependent on specific site conditions.
Investigation of Three-Phase Thyristor Converters under Generalized Impedance Unbalance
Authors: Manuel Weiland  , Gerhard Herold
Published: May 2017

Line-commutated current converters operated in electrical power systems will work asymmetrically, if the system is not balanced. This asymmetrical operation causes non-characteristic harmonics in the currents and therefore a higher distortion level. As a high distortion level is always disadvantageous, it is worthwhile to find appropriate methods to lower the distortion level by reducing the amplitudes of these non-characteristic harmonics. In this paper, three-phase thyristor converters operated in systems with unbalanced AC-line short-circuit impedances are investigated. To achieve a competent and well-grounded understanding of the problem a suitable method of calculation has been developed. This method firstly offers the opportunity to calculate the operation of line-commutated current converters in an unbalanced three-phase system. Furthermore it offers the opportunity to optimize the operation of the unbalanced system. This optimization is done by balancing the systems operation and reducing the amplitudes of the non-characteristic harmonics using asymmetrical firing angles.
Spanish microgrids: current problems and future solutions
Authors: G. Fernández  , M. Trujillo  , J. F. Sanz  , J. Sallán
Published: May 2017

Some years ago microgrids (µ-grids) became the most promising solution to the problems of the current electric system. There are many studies that demonstrate the advantages of using µ-grids, among which the following can be highlighted: microgrids can improve power quality inside and outside them; supply reliability of the internal loads is higher [1][2]; and the generalization of µ-grids could extend the usage of distributed generation (DG) systems. Despite being very extended in the scientific and engineering world, the µ-grid concept is not usual in the ordinary world. Proof of this is that current electric legislation does not include their usage. Prior to its spread, µ-grids must have an appropriate legal and economic environment. Through this text, the authors would like to show the legal limitations that the µ-grids usage will find in Spain and the solutions that are applied in other countries and states. The final objective of this paper is to present a legal and economic framework that would promote the development of µ- grids in Spain.

Hydrogen Production for Solar Energy Storage
Authors: P. Moldrik a  , Z. Hradilek
Published: May 2017

Using solar energy in photovoltaic power plants is an important method of electricity generation from renewable sources. Its potential is vast and technically easy to utilise. At present, photovoltaic power plants are the fastest-growing renewable energy source (RES) in the Czech Republic. Their installed capacity reached 1390 MWp (December 2010). Only in the last two years more than 1300 MWp was put in operation. This rapid development of photovoltaic sources is having a negative effect on the electric power system control. One option for mitigating this effect is to store the energy generated by photovoltaic in times of excess power in the grid and supply it to the grid when required, i.e., during peak periods of the daily load curve. There are numerous different storage technologies. The hydrogen system can be used to provide for storage of electric power in large amounts as well. This paper describes the state-of-the-art in the field of our research into solar energy storage in the Technical University of Ostrava.

Published: May 2017

Thermal solar energy offers a huge opportunity to reduce fuel dependency and environmental impact created by fossil fuel consumption. One of the main disadvantages of this renewable energy is its intermittence which decreases thermal solar power plants performance. In order to reduce cost electricity is necessary to create thermal solar plants which include thermal storage. There are different options of thermal storage: sensible, latent and chemical heat. It has been demonstrated that latent heat could store large amount of energy per unit mass. Moreover, latent heat storage could store fusion heat at a constant temperature which is the phase transition temperature of the phase change materials (PCM). However, these materials have a critical limitation that needs to be resolved in order to reduce operation cost of solar plants. This limitation is their low heat conductivity. This paper gathers the main solutions that are being analyzed in order to increase the possibilities to use PCMs in a high temperature thermal storage that is essential to develop optimum thermal solar power plants

Authors: Fernandes Maria Gilderjane Silva , Silva Filho Luís Abel da
Published: May 2017

O processo de industrialização brasileira ocorreu de forma concentrada, de modo que as regiões Sudeste e Sul sobressaíram em relação às demais. Políticas de desconcentração industrial foram elencadas com o fito de promover redistribuição da indústria em todo o território nacional. Destarte, é pretensão deste artigo analisar a dinâmica industrial brasileira e nordestina à luz das políticas de desconcentração industrial. Do ponto de vista metodológico, recorreu-se a uma revisão de literatura e, em seguida, à utilização de métodos de analise regional, a partir de dados da Relação Anual de Informações Sociais – RAIS do Ministério do Trabalho e do Emprego – MTE. Os principais resultados mostram que o processo de desconcentração industrial ocorre de forma ainda concentrada no eixo Sudeste e Sul, com perda de participação daquele e ganho relativo deste. Além disso, a redução acontece de forma pífia, sendo que ainda há forte concentração industrial nas regiões de maior dinamismo econômico. No que se refere ao Nordeste, a dinâmica da região ocorre com forte concentração nos estados da Bahia, Pernambuco e Ceará, sendo relativamente leve o ganho de participação dos demais ao longo dos anos.
Evolução dos sistemas agrários no território de produção do “abacaxi terra de areia” no litoral do Rio Grande do Sul

Published: May 2017

O cultivo do abacaxi conhecido como abacaxi “terra de areia” é desenvolvido em pequenas propriedades no Litoral Norte do Rio Grande do Sul. A região é a maior produtora de abacaxi do estado. Uma das possibilidades de agregar valor ao abacaxi seria através de uma Indicação de Geográfica (IG). Nosso estudo faz parte de um projeto de pesquisa que pretende levantar dados e discutir o potencial do abacaxi “terra de areia” em obter uma IG. Sendo um requisito identificar a origem da cultura na região e sua história, utilizamos a metodologia dos sistemas agrários (SA). O objetivo do artigo é apresentar os resultados dessa pesquisa: a reconstituição dos sistemas agrários do Litoral Norte do RS, situando o cultivo do abacaxizeiro na história da região. Num contexto histórico longo, vimos que o cultivo do abacaxi é bastante recente e que sua implantação está relacionada à busca de alternativas para as propriedades rurais dessa região. Pudemos constatar também que o núcleo urbano que deu origem ao município Terra de Areia, que empresta seu nome ao abacaxi, surge aproximadamente no mesmo período: ambos a partir da década de 1940. Os primeiros abacaxizeiros passaram por um período de adaptação e seleção natural e artificial de algumas décadas. A condição de solo em Terra de Areia foi apontada como um fator importante para o estabelecimento do abacaxi. Nos locais onde o solo é mais fértil, os produtores passaram a se dedicar a outros cultivos.
A pobreza rural no estado do Espírito Santo: invisibilidade e ações de enfrentamento a partir da implementação do programa incluir no campo
Authors: Rodriguez Celia Jaqueline Sanz , Conterato Marcelo Antonio
Published: May 2017

O tema pobreza, incluindo a extrema pobreza rural, é alvo de inúmeras reflexões acadêmicas e de ações de enfrentamento por parte do poder público. O objetivo deste artigo é fazer uma análise do Programa Incluir no Campo que atuou com famílias residentes no meio rural em situação de extrema pobreza no estado do Espírito Santo. Para a análise do programa realizamos entrevistas semiestruturadas com gestores e extensionistas rurais, análise de dados censitários sobre a pobreza no estado do Espírito Santo e também estudo sobre os principais aspectos que orientam o Programa Incluir no Campo. Entre os extensionistas entrevistados há consenso da inapropriedade do uso exclusivo da variável renda para a seleção das famílias a serem beneficiadas pelo Programa e, sobretudo, a invisibilidade das pessoas em situação de extrema pobreza no meio rural. Do ponto de vista quantitativo, os dados censitários evidenciam diferenças significativas em relação à intensidade do fenômeno pobreza na comparação entre rural e urbano. Por último, a análise do Programa apontou uma nítida contradição entre os pressupostos da perspectiva das capacitações, presentes na sua concepção, e a utilização do fator renda como critério para definição do público-alvo.

ABSTRACT

 

Quantitative Structure-Activity Relationship (QSAR) study have been conducted to  antimalarial active compounds of cassane-type diterpenes isolated from seed kernels of Bagore (Caesalpinia crista Linn.), using the atomic net charges data resulted from AM1 method of semi-empirical calculations. The aim of this research is to determine the mathematic equation model of quantitative structure-activity relationship from antimalarial active compounds of cassane-type diterpenes isolated from seed kernels of Bagore (Caesalpinia crista Linn.) using the electronic parameter of AM1 method. The best QSAR equation model was determined by multiple linier regression analysis and tested by leave-one-out type of cross validation methods. The result indicates that the biological activity is represented by a linier function of activity versus atomic net charges of C1,  C2, C3, C4, and C6 which is expressed by :

Log (1/C) = -7,362(+ 4,251) qC1 +3,258 (+ 4,590) qC2 + 11,038 (+4,485) qC3 + 29,421  (+20,542) qC4 + 19,849 (+6,171) qC6 + 8,541 (+2,256)

The equation is significant at 95% level. The cross validation analysis give minimal value of PRESS=64,372 and SEP = 2,93; where Log (1/IC50) = biological activity and q = atomic net charges

In 2013, raw pork was the suspected vehicle of a large outbreak (n = 203 cases) of Salmonella Muenchen in the German federal state of Saxony. In 2014, we investigated an outbreak (n = 247 cases) caused by the same serovar affecting Saxony and three further federal states in the eastern part of Germany. Evidence from epidemiological, microbiological and trace-back investigations strongly implicated different raw pork products as outbreak vehicles. Trace-back analysis of S. Muenchen-contaminated raw pork sausages narrowed the possible source down to 54 pig farms, and S. Muenchen was detected in three of them, which traded animals with each other. One of these farms had already been the suspected source of the 2013 outbreak. S. Muenchen isolates from stool of patients in 2013 and 2014 as well as from food and environmental surface swabs of the three pig farms shared indistinguishable pulsed-field gel electrophoresis patterns. Our results indicate a common source of both outbreaks in the primary production of pigs. Current European regulations do not make provisions for Salmonella control measures on pig farms that have been involved in human disease outbreaks. In order to prevent future outbreaks, legislators should consider tightening regulations for Salmonella control in causative primary production settings.

A new rapid assay for detecting oseltamivir resistance in influenza virus, iART, was used to test 149 clinical specimens. Results were obtained for 132, with iART indicating 41 as ‘resistant’. For these, sequence analysis found known and suspected markers of oseltamivir resistance, while no such markers were detected for the remaining 91 samples. Viruses isolated from the 41 specimens showed reduced or highly reduced inhibition by neuraminidase inhibition assay. iART may facilitate broader antiviral resistance testing.
