The economic efficiency of the cultivation of grapes as a branch of agriculture depends on the adaptation of grape varieties to the soil and climatic conditions of the place of growth. When developing new agricultural practices and technological solutions for the cultivation of grapes, it is necessary to assess the econom-ic efficiency of the proposed innovative ap-proaches. The cultivation of such grape varie-ties is becoming important and relevant, which, with high productivity and the use of differen-tiated care technology, require minimal costs when servicing the bushes and harvesting. In-creasing labor productivity in the viticulture industry is the most important condition for the intensive development of production. One of these conditions today is the formation of a bush according to the technology element, the shape of a bush AZOS-1, which allows to re-duce the cost of care and harvesting of grapes. The conducted research on the technology of cultivation of table grape varieties in connec-tion with the use of a new form of bush made it possible to economically substantiate the economic efficiency of growing grapes.

A ampliação do campo das políticas públicas, a partir da década de 1980 no Brasil, tem provocado o surgimento de uma diversidade de práticas nas quais se dirigem novas demandas para o campo da psicologia.  Com o intuito de problematizar o efeito destas demandas na reconfiguração deste campo, tomamos a naturalização como eixo norteador. Desenvolvemos inicialmente nosso argumento partindo da análise da naturalização como um elemento que se fez presente desde a instauração da psicologia, considerando as crises que operam em seu desenvolvimento desde o momento que ela se impôs a tarefa de renovação e ultrapassagem de modos de compreensão naturalizantes.  Esta renovação é um fato histórico que se repete no desenvolvimento da psicologia mantendo-se como uma tarefa sempre incompleta. Assim, para formularmos aspectos relativos às especificidades dos efeitos da naturalização das demandas nas instituições nos dedicamos a um retorno às elaborações iniciais dos analistas institucionais que se realizaram no contexto das manifestações de maio de 1968. De posse destes elementos passamos à análise do contexto atual das políticas públicas, partindo de uma reflexão sobre a inteligibilidade neoliberal e o quanto ela vem transversalizando tanto a dimensão das demandas quanto das práticas da psicologia. Depois avançamos sobre algumas considerações do quanto o redimensionamento da relação da política com a clínica pode criar alternativas perante as modulações do capitalismo vigente.

ResumenPresentamos en esta investigación el análisis de un tema de actualidad a través de la realidad representada en la ficción y la realidad mediatizada en la información. Debido a la naturaleza del objeto de estudio – las telecomedias españolas –realizamos un estudio de caso de tal modo que podamos comparar el tratamiento que el tema propuesto en los medios de comunicación, concretamente en la prensa, frente a la manera de exponerlo en las tramas de los capítulos de las series. Para analizarlo hemos considerado conveniente realizar un análisis narrativo audiovisual cualitativo a un tema estrechamente relacionado con la actualidad del periodo que se plantea en este estudio y que está presente en las series analizadas: 7vidas y aquí no hay quien viva. El tema elegido es la implantación de la Ley Antitabaco 28/2005 de 26 de diciembre y que fue recogida por ambas telecomedias en el primer capítulo que emitieron en el mismo mes de la promulgación de la ley. Abstract We present in this study the analysis of a current issue through the reality represented in fiction and reality mediated in information. Due to the nature of the object of study - the Spanish sitcom- conducted a case study so that we can compare the treatment that the proposed topic in the media, particularly in the press, in front of the way to put in chapters of the series. To analyze this we considered advisable to conduct a qualitative visual narrative analysis a subject closely related to current period arising in this study and is present in the series analyzed: 7 vidas and Aquí no hay quien viva. The theme is the implementation of the anti-smoking law 28/2005 of December 26 and was picked up by two sitcoms in the first chapter that issued in the same month of the enactment of the law. Palabras claveRepresentación, series de televisión, prensa, análisis cualitativo, 7 vidas, Aquí no hay quien viva.KeysworksRepresentation, spanish television fiction, press, qualitative analysis, 7 vidas, Aquí no hay quien viva.

A current issue of relevance for Mexico is the aging of the population, its demographic history has been strongly related directly to political and economic decisions. The ageing population faces significant income-generating challenges, which are essential to meeting its basic health needs, which are increasing considerably. For what is transcendental to characterize as precarious labour has permeated the elderly of the State of Hidalgo, on the basis of the integration of socio-demographic and economic indicators that allow the exploration of the conditions in which this segment of the population finds itself, which is growing every day and serves as an instrument for the generation of public policies.

This chapter examines the principles of integrated pest management (IPM). IPM often is defined as a program that, in the context of the environment and the population dynamics of pests, uses many different techniques and strategies in as compatible a manner as possible to maintain pest population levels below those causing economic injury. The concept of IPM was initially developed in traditional agriculture, where the success of a crop was measured in economic yield (quantity and quality of produce). The key to such agricultural IPM programs has always been establishing consistent and reliable “economic thresholds” — pest populations at which the cost of expected crop damage exceeds the cost of implementing control. In turf, the expected economic benefit from reducing a pest population usually is much more difficult to measure than in agriculture. It is difficult, if not impossible, to determine the economic value of suppressing pest insects. As a result, “economic thresholds” in turf IPM usually are more accurately described as “tolerance levels,” or “action thresholds.” In a turf IPM program, the turf manager must determine what pest populations can be tolerated without incurring unacceptable damage. The basic components of an IPM approach include assessing a site, monitoring and predicting pest activity, setting thresholds, managing turf stress, identifying and optimizing management options, and evaluating the results.

Abstract The Colorado potato beetle ranks as one of the most important potato pests, mainly due to its high feeding rate during all developmental stages, particularly third and fourth larval instar, and high fecundity. The effect of essential oil (EO) from anise (Pimpinella anisum L. [Apiales: Apiaceae]) prepared as conventional and encapsulated (EN) formulations on the mortality and antifeedant responses of young larvae of Colorado potato beetles was studied to evaluate the insecticidal and antifeedant effects of five concentrations of this EO and to assess the persistence of both formulations on potato plants. The EN formulation had a significantly higher residual amount compared with that of the conventionally formulated EO. Significantly different values of LC50 and LC90 (ppm) were established for the EO (LC50 = 1,700 and LC90 = 9500) and EN (LC50 = 3,100 and LC90 = 14,300) formulations. The effects of both P. anisum formulations (EO and EN) applied topically to Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) larvae were distinctly different from those observed with the contact treatment. At the highest concentration of 20,000 ppm, the mortality of the second instars of the L. decemlineata larvae did not exceed 25%. On the other hand, both tested formulations of P. anisum were highly effective when administered orally. The encapsulated EO formulation achieved a distinctly higher biological activity. Our results confirm that the EO from P. anisum, especially the encapsulated formulation, has high insecticidal properties that may lead to the development of new organic products for the control of Colorado potato beetles.
