SURVEY ON V. CHOLERAE, V. VULNIFICUS AND V. PARAHAEMOLYTICUS IN BIVALVE MOLLUSCS OF THE ADRIATIC SEA AND PROPOSAL OF AN ANALYTICAL PROTOCOL

Bivalve molluscs from Adriatic sea were analyzed for V. parahaemolyticus, V. cholerae e V. vulnificus presence. The isolates on TCBS Agar and m-CPC Agar were selected on the basis of a new biochemical screening, that showed a good performance, because among 2344 strains from primary culture only 237 (10%) were presumptively assigned to the species of interest. The PCR analyses was performed for the target genes toxR hlyA, ctxA, tcpI (V. cholerae), toxR, tl, tdh, trh (V. parahaemolyticus), vvhA and viuB (V. vulnificus). Among the 9 strains confirmed to belong to V. parahaemolyticus specie, 6 were sucrose positive. On 215 samples of molluscs only 5 resulted positive for V. parahaemolyticus being toxR+, tl+, although non pathogenic (tdh-, trh-), and none for V. cholerae e V. vulnificus

Design criteria of the bolometer diagnostic for steady-state operation of the W7-X stellarator

A bolometric diagnostic system with features necessary for steady-state operation in the superconducting stellarator W7-X was designed. During a pulse length of 1800 s with an ECRH (electron cyclotron resonance heating) power of 10 MW, the components suffer not only from a large thermal load but also from stray radiation of the nonabsorbed isotropic microwaves. This paper gives an overview of the technical problems encountered during the design work and the solutions to individual problems to meet the special requirements in W7-X, e.g., component thermal protection, detector offset thermal drift suppression, as well as a microwave shielding technique. © 2010 American Institute of Physic

Group polarization effect on decisions by selected Kenyan secondary school disciplinary panels

This study investigated social group phenomenon of group polarization effects on disciplinary hearing decisions in selected Kenyan secondary school. The participants were 78 school personnel (females = 42%and males 58%) from ten secondary schools with both unisex (n = 39) and co-educational schools (n = 39). Both quantitative and qualitative data were collected and analyzed. The results suggested group polarization effects in disciplinary hearing decisions, in that there were shifts from pre to post-disciplinary hearing decisions. Persuasive arguments and social comparisons significantly influenced group polarization decisions.Department of HE and Training approved lis

Lacunarity, lexicography and beyond: integration of the introduction of a linguo-cultural concept and the development of L2 learners’ dictionary skills

The paper discusses the integration of presenting theoretical linguocultural knowledge and developing dictionary skills in advanced students of a foreign language. The proposed approach allows showing students the interdisciplinary character of various issues, one of which is cross-linguistic lacunarity. It is given as an example of a phenomenon, whose introduction can be combined with the development of students’ dictionary use abilities. Lacunarity consists in the lack of some source language elements in the target language. Two main kinds of lacunae are distinguished: linguistic and referential ones. The focal issue of the paper is how the information on the lacunary character of words can be presented to advanced students of English as a foreign language, in this paper Polish learners, so that they could consider the phenomenon in terms of bilingual lexicography: first, becoming aware of the specifics of their description; second, practising their dictionary skills by analysing entries for selected lacunary lexical and phraseological units; third, combining the information and skills in doing creative tasks, related to lacunarity and its bilingual lexicographic descriptions. Furthermore, additional activities are proposed for revising the acquired knowledge on lacunarity and advancing dictionary use. Offering students tasks, which require them to adopt a different perspective, aims to increase their involvement in the learning process and to foster their autonomy as learners. Encouraging learners to reflect on lacunae and their lexicographic description is expected to familiarize them with the phenomenon and simultaneously to develop their dictionary skills by doing especially designed [email protected] University of Bialystok101-11

Impacts of soil conditions and light availability on natural regeneration of Norway spruce Picea abies (L.) H. Karst. in low-elevation mountain forests

& Key message Natural regeneration of P. abies (L.) H. Karst. may reach high densities in lower mountain elevations. The highest densities were found in sites with moderate light availability, with low pH, and not near the riverbank. However, age-height classes differed in the predicted magnitude of response, but were consistent in response directions. Mosses and understory species typical of coniferous forests were positively correlated with regeneration density. & Context Norway spruce Picea abies (L.) H. Karst. in Central Europe is at risk under climate change scenarios, particularly in mountain regions. Little is known about the impact of environmental factors on the natural regeneration of P. abies in lowelevation mountain forests. & Aims We aimed to assess impacts of distance from the riverbank, soil pH, and light availability on natural P. abies regeneration. We hypothesized that (1) natural P. abiesregeneration would depend on light availability and soil pH and (2) there are understory plant species which may indicate the microsites suitable for natural regeneration of P. abies. & Methods The study was conducted in the Stołowe Mountains National Park (SW Poland, 600–800 m a.s.l.). We established 160 study plots (25 m2 ) for natural regeneration, light availability, soil pH, and understory vegetation assessment
