The aim of this work was to investigate the effect of fertilizers on chemical composition of raw pumpkins and quality of processed pumpkin products. The material consisted of two Cucurbita maxima 'Stofuntovaja' and 'Bambino' pumpkins cultivar. Pumpkins were grown at the organic pomological garden of the Lithuanian Agricultural University in 2004-2005. The fertilization treatment was: organic-humatic - 30 l ha-1, complex fertilizers (10:10:20 - 500 kg ha-1, compost (mixture of composted manure 70% and plant waste 40%) - 40 t ha-1, complex + organic-humatic fertilizers - 500 kg ha-1 + 30 l ha-1. Biochemical composition and quality of processed pumpkins products (jams, bread and wine) was analyzed. It was determinate better biochemical composition in raw pumpkins grown with complex + organic-humatic fertilizers. Better sensual characteristics had products processed from pumpkins grown with organic-humatic fertilizers.

Supervised classification methods are applied in many fields. The main problem of applying these methods is how to select the most appropriate method in particular case. The literary review was fulfilled and the advantages and disadvantages of mostly used criterion of supervised classification methods comparisons were ascertained. Then the methodology of comparisons was suggested. The analysis of SAS system procedures and macro commands was made. It was ascertained that there is not comfortable software which allows comparing the results of supervised classification methods. This work demands a lot of work, good knowledge of SAS programming language and high qualification in programming. So, the main purpose of this work is to expand the statistical data analysis system SAS possibilities in comparison of supervised classification methods and classificate various data. In this work the possibilities of SAS system are expanded by the tool which allows comparing quality of the linear, quadratic, kernel, nearest neighbor’s discriminant analysis and logistic regression analysis methods. There were used classification error estimates which were got by resubstition, cross–validation leave one out, bootstrap and Monte Carl cross–validation methods, although classification error confidence intervals which were got by non-parametric bootstrap method. The test of created tool was made with various data (different sample sizes, various classis separability, violations of assumptions... [to full text]

Psychological peculiarities of the patiens with Parkinson‘s disease Objektives: the aim of this research was to assess and to compare characteristics of quality of life, depression and social support of the patients with Parkinson‘s disease and healthy ones. Methods: using Ferrans and Powers (1985) Quality of Life Index (QLI), wich measures general quality of life (QOL) and four domains – health and funktioning, social and economic, psychological/spiritual and family), Centre for Epidemiologic Studies Depression scale (CES – D), ( Radloff, 1977) and O‘Brien, Wortman, Kessler, Joseph (1993) social support scale was used to interview 60 patients with Parkinson‘s disease (mean age 67,2 years) and 73 healthy people (mean age 67,0 years). The Cronbach alpha coefficient for the QOL Lithuanian version was 0,94, for CES – D scale – 0,87. Results:the research showed that people with Parkinson‘s disease had lower QOL than healthy people (respektively 16,42 and 19,96, t = - 6,393, p = 0,001).Analysis between patients with Parkinson‘s disease and healthy respondents showed that patients with Parkinson‘s disease had in all domains lower QOL than healthy respondents and there were statistically significant differences in all domains (p < 0,05). The most difference in QOL average was found in scale of physical health (14,33 and 19,03 respectively, p < 0,05) proving that people with Parkinson‘s disease experience more serious problems.Research showed that the...

Milk quality is the rate which takes in a normal composition and a tipical characteristic. The standards and other documents like veterinary - sanitary instruction are making to secure and to control a quality of milk. In the period from 1938 to 2007 the standards of milk quality was changed very often and requirement of an animal welfare, of milk process and a primary milk processing, of staff hygiene and milk quality was tightened up. There was changed a primary milk quality valuation – for procurement milk temperature, acidity, milk cleanness and density. Most of all in the period from 1993 to 2007 was changed the norms and evaluation of milk bacterial pollution and somatic cell count. In 1970 in veterinary - sanitary instructions milk was sorted out, but in 2004 05 01 when Lithuania joined in to EU, sorts of milk was canceled.

Meat is one of the most important food products. European Union countries, including Lithuania, are the main meat producers in the world - their production comprises more than 16 % of processed meat. In the world commerce meat products conclude 12,8 % of market place, of which 39 % - pork. The purpose of the work - to analyse the preservative gas impact on freshness sustention of pork products. The main tasks are to review the freshness rates of pork products, their evaluation methods; to discuss the ways of long-lasting freshness sustention, which are usable in the processed food industry; to analyse the preservative gas method on the freshness sustention of meat products; to research and to compare the microbiological pollution of the sausages, packed in the preservative gas and not packed in it. The methods of research are: analysis of the primary documents; analysis of the secondary documents; analysis of the scientific literature; analysis of the statistics, microbiological research of pork sausages. The most effect of the preservative gas usable for the packing meat products is obtained by packing smoked sausages, which microbiological pollution after 20 days, increases 1,2 – 2 times.
