| Considering the need for reliable standardized routine toxicity tests for the marine environment, a short-term bioassay with <i>Artemia</i> nauplii has been developed for routine testing. The major reason for the selection of brine shrimp as test species is the continuous availability of <i>Artemia</i> under the form of dry cysts from which the larvae are hatched very easily. This unique advantage solves one of the major problems of aquatic ecotoxicological tests, namely stock recruitment and/or culturing; the <i>Artemia</i> test can be performed anywhere and at any time from dry biological material available "on the shelf".An extensive study has been performed on various brine shrimp tests published in scientific... |

| ABSTRACT: The phenological stage, post-harvest processing and quantity of material can interfere in the allelopathic activity of extracts. The objective of this study is to test the allelopathic effect of aqueous extracts of the leaves of Annoni grass (Eragrostis plana), an invader of natural pastures. Twelve extracts were prepared by combining the phenological stage of the plants when harvesting the leaves (vegetative; flowering), post-harvest processing before extraction (fresh; dry at 40 oC), and the amount of plant material (5, 15, and 25 g 100 mL-1 distilled water). Two bioassays were conducted in a germination chamber, with evaluation of germination and growth of seedlings of lettuce (Lactuca sativa) and white clover (Trifolium repens). The extracts... |

| ABSTRACT: The commercialization of ryegrass seeds with the presence of resistant biotypes is a serious issue that increses the dispersion of resistance to new areas without this problem. Therefore, this study aimed to develop a quick test to detect susceptible and resistant seeds to the glyphosate herbicide in order to identify contaminated seed lots with glyphosate resistance. Three experiments were carried out, one in greenhouse and the other two in the seed laboratory. First, the resistance factor (RF) was determined by a dose-response curve experiment in biotypes suspected to be resistant and susceptible to glyphosate. Then, the germination test was conducted with the selected biotypes under increasing glyphosate rates (0, 3.5, 6.9, 13.9, 27.8, 55.5,... |

| Benchmarking is the practice of establishing the relative performance of a business or enterprise against an appropriate standard, generally industry standards derived from a survey of farms. The Policy Commission into the Future of Farming and Food (2002) highlighted a need to spread and improve benchmarking on farms. The requirements of effective benchmarking are illustrated in a ten step framework. The ten steps illustrate the range of expertise and resources a manager requires before being able to justify allocating resources to benchmarking. A comparison of alternative farm surveys and methodologies used to collect, analyse and report industry standards illustrates the difficulties farmers can have in identifying appropriate, robust and accurate... |

| The growing importance and scope of technology transfer processes undertaken all over the world settles the question of the necessity for their proper identification. The multi-aspect character and complexity of these phenomena create specific problems in conducting analytic work. Although technology transfer is an element of the Science-Technology-Innovation (STI) system, it does not have a proper place in the existing methodology system of this area. The aim of this article is to point out the necessity to create a proper, complex and comprehensive methodology for researching technology transfer processes, which would contribute to better understanding of the processes themselves and at the same time enable their proper development. |

| This article aims to highlight the methodological bases and principles, sometimes implicit, that have served as support for the development of a referential similar to the one retained as part of the French decree on "Agriculture Raisonnée", namely the Quali'Terre referential. We show that the innovations introduced by this referential are of various natures: i) a change of perspective by taking a position at the level of the farming system and not of a given parcel of land or production, ii) use of the HACCP method for identification and most especially the prioritization of risks and the preventive measures to be implemented, iii) the introduction of the concept of continual improvement for the farmer. Even, if from an agronomic point of view, the... |

| This paper explains the development and implementation of a methodology for assessing the economic impacts of large-scale environmental regulations. The development process began with a literature review surveying channels through which environmental regulations might influence economic performance. Avenues deemed suitable were incorporated into a computable general equilibrium (CGE) model of the California economy. This model is based on the California Department of Finance's Dynamic Revenue Analysis Model (DRAM). Modifications to DRAM for the current project include a revised sectoring scheme that features industries of particular regulatory interest, revamped data matrices that accommodate this new sectoring scheme, a new air pollution module,... |
