introduction agricultural sustainability is regarded as a key factor for long term profitability of farming in rural areas. researchers believe that an agricultural system is sustainable if it includes environmental quality, economic viability, and employment and social performance. agricultural sustainability can be analyzed on diverse spatial scales, from the field to a regional, national or ...

1. 2. where I t has been pointed out that the S(')-bounded rudimentary predicates as given by Definition 6 of [1] do not possess the property asserted in the paragraph which starts on page 73 and ends on page 74. This may be corrected by replacing points 1, 2, and 3 of Definition 6 by the following: a(x, i, a) and ~ ( x , i, a) are in RUD s . I f c is a positive integer then both Q(x, u, v, w) ...

THE word ichthyosis is derived from the Greek word Ichthys meaning a fish. Patients with ichthyosis exhibit prominent scales occurring more or less diffusely all over the body. Usually the scales are large and centrally adherent with loose edges. Ichthyosis is a disorder of keratinization. Ichthyosis forms a group of genodermatoses transmitted by autosomal dominant or, as recently shown by Well...

Imprecise probabilistic beliefs are modelled as incomplete comparative likelihood relations admitting a multiple-prior representation. We provide an axiomatization of such relations for the case in which the set of priors is “convex-ranged”. We also show that the multiple-prior representation is unique whenever the set of priors is “almost-convex-ranged”. Such uniqueness ensures the adequacy of...

I am indebted to my advisor Juergen Eichberger for his helpful guidance and to Alexander Zimper for his helpful suggestions and illuminating discussions. I would like to thank Hans Haller, Clemens Puppe, Itzhak Gilboa, Hans Gersbach, Klaus Ritzberger, as well as the participants of the RUD conference in Evanston, of the FUR XI conference in Paris and of the PhD seminar at the University of Heid...

phytoplanktons are the first bio- indicators of pollution in aquatic ecosystems. phytoplankton assemblage and aquatic ecosystems are always influenced by environmental factors therefore these environmental changes and threats must be understood in any ecosystem. phytoplankton are inexpensive and readily available bio- indicators. in the present study, phytoplankton were used to study the sefid ...

INTRODUCTION In periapical surgery, the absence of standardization between different studies makes it difficult to compare the outcomes. OBJECTIVE To compare the healing classification of different authors and evaluate the prognostic criteria of periapical surgery at 12 months. MATERIAL AND METHODS 278 patients (101 men and 177 women) with a mean age of 38.1 years (range 11 to 77) treated w...

Morphological udder traits have recently become of greater interest from farmers to researchers. In dairy ewes, the udder is very important due to its physiological and conformational characteristics. External udder traits were measured in ewes (Ovis aries L.) of nine genotypes (355 ewes) created of the basis of Improved Valachian (IV), Tsigai (T), and Lacaune (LC) breeds (six traits; 1185 data...
