In this article an attempt was made to use the discriminant analysis to measure and evaluate the profitability of production types according to the economic size. Research was based on FADN database that included information about 615 production types according to the economic size from the European Union in the years 2004-2005.
This paper describes the indicators of the present and future economical situation. The discriminant analysis has been used. The real income increase, gross fixed capital formation and low USD/PLN exchange rate are the good prosperity indicators. The next year prosperity is indicated by high increase of the gross fixed capital formation, high current account and budget deficit values (as GDP %) and decreases of the private and public consumption expenditure, export and low unemployment rate at the end of the year.
Twelve morphometric variables of Cardaminopsis halleri individuals from four sites in upper silesia province were analyzed to establish the pattern of interpopulational relations. Two hundred plants were collected from two very polluted areas (near zinc-lead and zinc smelters) as well as from two other sites in unpolluted areas within the same bioclimatic region. stem size, dimensions of leaves and rosettes, as well as flower and seed numbers and in­dividual dry weights were studied using standard biometric methods. cluster analysis indicated overall differences among populations. Those four populations are different with respect to all variables. Discriminant function analysis confirmed seed number as the most important variable in the evaluation of interpopulational variability.
The aim of this study was to assess the financial situation of enterprises producing feeds, focusing on the potential risk of bankruptcy. Selected Polish models of discriminant analysis were used for the assessment of the financial condition of enterprises. Studies have shown that between the years 2006 to 2011, Cargill Polska, De Heus and Polmass had a good financial situation. The situation of PPUH Pasz Konspol and Fel Pasz was unfavourable, whereas Agrocentrum and Eurolpol were in a poor situation between 2007 and 2008. The assessment of the financial condition, by means of the applied early warning models, was not unequivocal for medium and small enterprises.
A new species of the digenean family Brachycladiidae Odhner, 1905 is described from the bile ducts of a Gervais’ beaked whale Mesoplodon europaeus Gervais (Ziphiidae) stranded on the North Atlantic coast of Florida. These parasites were assigned to Brachycladium Looss, 1899 and differed from other species of the genus in the relative size of the oral and ventral suckers, the form and size of the eggs and their extremely small body size. A canonical discriminant analysis was used to examine differences between these specimens and the smallest available individuals of B. atlanticum (Abril, Balbuena and Raga, 1991) Gibson, 2005, considered the morphologically closest species. The overall results exhibited significant differences between the two samples and a jack-knife classification showed that 96.2% of the specimens were correctly classified to their group. In view of evidence from morphological data, the specimens from M. europaeus are considered as new to science and are designated as Brachycladium parvulum n. sp.
Our study analyzed the fire (pyric) environment (vegetation or fuels, meteorology, topography, suppression time) of the large forest fires (greater than 1,000 ha) that occurred in Greece during 1990-2003. Statistical analysis of 84 large fires (representing 0.37% of the total number of fires) revealed that they usually spread under moderately to low relative humidity (21-40%) in the presence of strong to moderate northern winds. Approximately one-fourth of all large fires occur during heat waves (i.e. air temperature higher than 30℃ and air relative humidity 21-40%). Large fires occur as both surface and crown fires and usually spread in dense vegetation with a continuous duff layer. Successful containment requires a combination of both ground and aerial fire suppression forces. Although large forest fires usually have short initial attack time (less than 30 minutes), the suppression time is variable. The main differences between the large fires and all the others lie in the prevailing wind speed (strong for large fires, moderate for smaller fires) and the mode of propagation (mixed surface and crown spread for large fires, only surface spread for smaller fires). However, no unique characteristics of large fires were found that would distinguish them from smaller fires. This supports the hypothesis that any fire may become large under certain circumstances. The results of this study could be useful in forest fire danger rating and presuppression alertness in the context of judicial fire prevention and suppression planning.
Analizowano zmienność plonowania 8 odmian pszenicy ozimej na Dolnym Śląsku w latach 2001–2003 na podstawie Krajowego Programu Porejestrowego doświadczalnictwa Odmianowego. Plony odmian z pięciu miejscowości — środowisk Polski południowo-zachodniej porównywano w warunkach intensywnej i standardowej uprawy roli. Odmiany Kris, Jawa i Kobra odznaczały się istotnie wyższymi plonami w porównaniu do pozostałych obiektów zarówno w systemie intensywnej uprawy jak również w wariancie standardowym i powinny być zalecane do uprawy na terenie Dolnego Śląska. Natomiast znaczne obniżenie plonowania odnotowano u odmian Zyta i Soraja w systemie uprawy charakteryzującym się niższą dawką nawożenia azotowego i brakiem stosowania fungicydów. Analiza dyskryminacyjna wykazała zróżnicowany wpływ środowiska (miejscowości) na zmienność plonowania odmian pszenicy. Na kompleksach pszennym bardzo dobrym i dobrym uzyskano istotnie wyższe plony w porównaniu do kompleksu pszennego wadliwego i żytniego bardzo dobrego.
