When solving electromagnetic problems, integral equation methods, such as the Method of Moments, are known to yield to dense matrix systems whose solution usually supposes an intensive computational cost. Continuous efforts have been developed to overcome this drawback. In this paper, the goal is to generate a set of basis functions defined over the entire domain and characterized by a null radiated power coupling in the far-field region. This behavior permits to diminish the density of unknowns per wavelength, considering only a reduced set of the new basis. Furthermore, the resulting matrix has a sparse structure. All these factors amounts to considerable savings in terms of computer storage and CPU requirements. [less ▲]

Two high-resolution far-UV spectra of the low-excitation planetary nebula HD 138403 are analyzed which were obtained with the IUE satellite over the wavelength range from 1170 to 2070 A. It is shown that the nebula's far-UV spectrum comprises a stellar continuum on which are superimposed a few emission lines, numerous interstellar absorption lines, and various types of P Cygni profiles. Evidence is examined for substantial mass loss from the central nucleus, with terminal velocities of the order of 800 km/s. The observed nebular emissions are used to derive the electron density in the main nebula. The results are taken as supporting the hypothesis that a bipolar structure is expanding around HD 138403 via a selective radiation process involving an edge- or line-locking mechanism or both.

Because we acknowledge both the importance of the geographical context on agritourism and the richness of benchmarking, discussions aim to underline and to understand original agritourism practices in relation to their spatial context. According to Sznajder et al. (2009) attention has to be paid to the historical structure of economy, the state of farming, the demographic situation, the accessibility, the social attitudes, the capital resources. Therefore the structure of the farms, the available labour force and buildings, the capital resources as well as the surroundings (including landscape features, natural and cultural heritages) comprise the main characteristics. This special issue aims to explore both the local impacts of agritourism development and the positioning of agritourism on tourist market. [less ▲]

Based on evidence from nine countries (UK, Belgium, France, Germany, Italy, Poland, Croatia, Slovenia, and Ireland), this special issue analyses the fabrics of farm tourism in Europe. It identifies two main development trends: on one hand, a small scale and dispersed activities, at the other hand a product in response to tourist market demand. A brief overview of existing farm tourism practices in the European rural areas indicated an interesting interface between the forms and dimension of farm tourism embeddedness in local environment and at the same time, the ways and range of internationalization of farm tourism business.

Our aim was to identify elements useful in designing policies and programmes for conservation of farm animal genetic resources, taking as case study a group of European local cattle breeds. We first investigated the implications of differences among countries in the policies and programmes to be developed. Secondly, we analysed key elements common to countries, which may affect local breed viability. We used the herd size trend expected by the farmer in the near future as an indicator of breed viability. Fifteen breeds, for a total of 355 farms, were surveyed. To take into account the multiple factors influencing breeds’ demographic trends, the questionnaire included economical, technical and social aspects. Among the major differences across countries was the perception of the farmer on the value attributed to the local breed by society. Concerning the elements common to countries and their association to breed viability, the greater the collaboration among farmers and the stakeholders’ appreciation as perceived by the farmer, the greater the viability of the farm. An opposite trend was observed for the age of the farmer. Older farmers generally planned to soon cease farming or decrease herd size, whereas young farmers planned to increase the size of their herds. Implications of including these elements in conservation polices are discussed. [less ▲]

This study analyzes farmers' practices and willingness to adopt supplemental irrigation on rainfed crops in the Sahelian and Sudano-Sahelian areas of Burkina Faso. A survey of 629 farmers revealed a diversity of farming practices within and between two agro-climatic zones. Over 65% of farmers believe that supplemental irrigation is a good way to mitigate the adverse effects of dry spells on crop yields. Determining factors of farmers’ willingness to adopt supplemental irrigation were identified using a logistic model. Lack of information is the major obstacle to promoting this innovation. Farmers’ training and information dissemination are the best ways to increase the acceptance of this promising technology. [less ▲]
