La politique régionale : entre compétitivité et respect de l'environnement

Aujourd'hui plus que jamais, le développement économique ne peut se faire au détriment de notre environnement naturel. Dès lors se pose la question de savoir comment parvenir à maintenir la compétitivité d'une économie, tout en tenant compte de l'impact qu'elle a sur révolution du cadre naturel. La présente recherche propose d'investiguer sur la question en se penchant sur les politiques publiques de promotion économique, et plus spécifiquement sur la politique régionale. Faut-il maintenir la confiance dans les courants néoclassiques, comme le laisse supposer la situation actuelle, renforcer la position d'une économie s'inscrivant au sein d'un cadre socio-environnemental ou encore repenser notre mode de fonctionnement économique quant à son développement ? Dans le cas présent, la politique régionale suisse est évaluée à la lumière de trois stratégies de développement économique. D'une part, il y a l'économie fondée sur la connaissance. Cette dernière est à la base de la philosophie actuelle en matière de politique régionale. Ensuite, il y a l'écologie industrielle, qui pour sa part fait la promesse d'un développement économique éco-compatible. Enfin, la troisième stratégie est celle de l'économie de fonctionnalité, qui propose de maximiser l'efficience d'une unité de matière première en limitant notamment la notion de propriété. Au travers d'une grille d'analyse construite sur le modèle des géographies de la grandeur, les trois stratégies sont confrontées aux objectifs de la nouvelle politique régionale suisse (NPR) ainsi qu'à ses modalités de mise en oeuvre. Il en ressort qu'en l'état actuel, la stratégie misant sur l'économie de la connaissance est la plus à même de relever le défi d'un développement économique durable. Toutefois, moyennant adaptations, les autres stratégies pourraient également se révéler être pertinentes. On constate notamment que les éléments clés sont ici l'innovation, ainsi que les dimensions spatiale et temporelle des stratégies. Nous recommandons dès lors d'adopter une approche territorialisée du développement économique, selon une logique de projet au sens de Boltanski & Chiapello. A notre sens, seules les propositions à même de fédérer les acteurs et disposant d'une vision intégrée du développement ont une chance de permettre un développement économique en harmonie avec notre cadre environnemental. - Today more than ever, economic development can't go ahead without consideration for our natural environment. This lays us with the question of how to maintain the competitiveness of an economy, and at the same time to manage the impact of it on the natural frame. This research aims to investigate this question through public policies fostering economy, more specifically through the regional policy. Must one trust the neo-classical way, as the actual situation let's think about it, reinforce the position of an economy within a socio- environmental frame or moreover reinvent our economical modus regarding development? In this case, an assessment of the Swiss regional policy is lead through three strategies of economic development. First, there is the knowledge economy. It is the core concept of the actual philosophy regarding regional policy. Second, there is the industrial ecology which aims to promote an eco-compatible economic development. Last, there is the functional economy, which proposes to maximize the efficiency of every used unit of natural resources by limiting in particular the notion of propriety. Through an analytic frame built on the model of geographies of greatness (géographies de la grandeuή, the three strategies are confronted to the objectives of the Swiss new regional policy (NRP) as well as its implementation. It turns out that actually, the strategy laying on the knowledge economy happens to be the best solution in order to promote a sustainable economic development. Nevertheless, with few adaptations, the other strategies could be pregnant as well. What we can see is that key- elements are here the innovation, as well as the spatial and temporal dimensions of these strategies. We recommend therefore to adopt a territorialised approach of economic development, with a project-based logic as meant by Boltanski & Chiapello. We are convinced that only propositions which are able to unit actors, and with an integrated point of view, have a chance to promote economic development in harmony with our environmental frame.

Development of an Improved Agricultural-Based Deicing Product, TR-581, 2010

Snow and ice removal on public streets is a critical part of the work of departments of transportation in northern U.S. states, including Iowa. Iowa is also a state rich in agricultural resources, some of which undergo industrial processes that generate a number of byproducts, e.g., in converting corn to ethanol or soy to biodiesel. It would be desirable to find those that, with a minimum of additional processing, can be used as a deicing compound, either alone or in combination with products currently in use. The focus of this work is therefore to investigate by-products from agricultural processes that may be suitable for use as deicing applications. This topic has been investigated in the past by others, with many patented products described in the literature. An initial screening was carried out to assess the potential acceptability of selected commercial products, as well as a glycerol developed for this project. Based on the variety of parameters tested, the product combination that shows the greatest promise for future application consists of 80% glycerol with 20% NaCl.

Avaliação da capacidade de regeneração in vitro em tomateiro industrial

Este trabalho teve por objetivo avaliar a capacidade de regeneração das cultivares de tomateiro industrial (Lycopersicon esculentum Mill) IPA-5 e IPA-6, utilizando quatro composições de meio de cultura descritos na literatura e cinco variações de inoculação. Foi testada uma nova variação de inoculação, denominada cotilédone fendido. A maior freqüência de formação de gemas vegetativas foi 100% no caso de IPA-5, e 65% no caso de IPA-6. Para induzir o alongamento de brotos, foram necessários três subcultivos dos explantes apresentando gemas. No caso de IPA-5, o número de brotos obtidos foi maior quando a indução de gemas foi realizada em meio contendo BAP (2,5 mg L-1) e AIA (0,2 mg L-1) seguido de três subcultivos, em meio como zeatina (0,5 mg L-1). Usando esse protocolo, a cultivar IPA-5 produziu uma média de 5,45 brotos alongados a partir do cotilédone fendido. Essa capacidade excedeu significativamente o cotilédone aparado, que produziu 4,4 brotos alongados por explante. No caso de IPA-6, a melhor combinação de meios e método de inoculação produziu 0,87 broto alongado por explante. Os brotos alongados foram enraizados e transferidos para casa de vegetação.

La rehabilitación y el uso del patrimonio histórico industrial

La reutilización de edificios industriales es un aspecto del proceso de reconversión de suelo industrial en otros usos, el cual se ha acentuado con la reestructuración industrial ligada a la aparición de lo que se denomina ciudad postindustrial. Dicho proceso ha llevado con frecuencia al abandono y a la degradación de los viejos edificios industriales, que muchas veces son derribados y sustituidos por otros nuevos dedicados a viviendas o a usos terciarios. En los dos últimos decenios, sin embargo, la conservación y la reutilización del patrimonio histórico industrial ha adquirido una gran importancia. Los viejos edificios industriales funcionalmente obsoletos poseen, en efecto, valores arquitectónicos y técnicos que hacen a veces necesaria y posible su conservación y reutilización adaptativa. Pero eso exige definir claramente criterios de selección, tras un proceso de inventario y catalogación, en el que deben tenerse en cuenta los criterios generales de catalogación del patrimonio histórico monumental. El artículo discute la conveniencia de conservar edificios funcionalmente obsoletos y aborda la cuestión de las estrategias de defensa, haciendo alusión al papel de los técnicos y a la necesidad del compromiso local.

Influência do manejo do solo e da rotação de culturas na qualidade industrial do trigo

A qualidade industrial do trigo é afetada por fatores genéticos e ambientais, como solo, clima, tratos culturais, e outros. O presente trabalho teve como finalidade avaliar o efeito de sistemas de manejo de solo e de rotação de culturas sobre características que definem a qualidade industrial de trigo (peso do hectolitro, peso de mil grãos, extração experimental de farinha, alveografia, teste de microssedimentação com lauril sulfato de sódio e número de queda). O delineamento experimental foi em blocos ao acaso, com parcelas subdivididas e três repetições. A parcela principal foi constituída pelos sistemas de manejo de solo (plantio direto, preparos convencionais de solo com arado de discos e de aivecas, e cultivo mínimo), e a subparcela, pelos sistemas de rotação de culturas (monocultura, um inverno e dois invernos sem trigo). O preparo convencional de solo com arado de discos e o cultivo mínimo reduziu o número de queda; o sistema de rotação com dois invernos sem trigo elevou o peso do hectolitro; a monocultura desse cereal reduziu o peso do hectolitro, elevou a força geral de glúten e a microssedimentação com lauril sulfato de sódio; a interação sistemas de manejo de solo, rotação de culturas e ano de cultivo afetou o peso de mil grãos e, o ano de cultivo teve grande influência em todas as características de qualidade industrial de trigo estudadas.
