Tvorba výnosu a kvalita ozimé pšenice v podmínkách setrvalého pěstování / The yield formation and quality of winter wheat in low-input conditionsPAVLÁTOVÁ, Kristýna January 2019 (has links)
The aim of this thesis is to evaluate basic yield formation and food quality of grain in selected winter wheat varieties, depending on the intensity of cultivation. There was 5 varieties chosen for the experiment of which 3 was linear (Patras, Turandot and Rumor) and 2 varieties was hybrid (Hyfi and Hybery). Each variety was repeated three times during the experiment. The vegetation was assessed in two variations - the checking one and the one fertilized by the nitrogen. This experiment was conducted in growing season 2017/2018 on the field of Faculty of Agriculture of University of South Bohemia. The withdrawal of the vegetal material for the purpose of the following sample analysis was done right before the harvesting. The yield formation and the health condition of the vegetation was assessed in the fieldwork. The determination of qualitative parameters was made with the help of the apparatus in the laboratory of the faculty. Then, the results was marked in tables and graphics. Finally, the statistical evaluation of the obtained data. An average yield of all assessed varieties of the winter wheat was 8,52 t.ha-1 at the checking variation. On the contrary, at the nitrogen fertilized one the average yield was 8,94 t.ha-1. The evaluated varieties in the growing season 2017/2018 had the baking quality A and B. Regarding the qualitative parameters, there was found lower values of volume quantity than those that are stated in the norm for the food wheat (at least 76,0 kg.hl-1). The highest values were found at the variety Turandot fertilized by nitrogen (77,8 kg.hl-1), which met the requirements of the ČSN 4611 00-2.

UtilizaÃÃo da ultrassonografia e qualidade da carne de cordeiros Santa InÃs de diferentes classes sexuais submetidos à restriÃÃo alimentar / Use of ultrasound and quality of lamb meat Santa InÃs of different genders subjected to food restrictionDayanne Lima de Sousa 24 February 2015 (has links)
FundaÃÃo de Amparo à Pesquisa do Estado do Cearà / Objetivou-se com o presente estudo avaliar a utilizaÃÃo da ultrassonografia e qualidade de carne de cordeiros Santa InÃs de diferentes classes sexuais submetidos à restriÃÃo alimentar. Foram utilizados 30 cordeiros, 15 castrados e 15 nÃo castrados, com aproximadamente dois meses de idade e peso corporal inicial mÃdio de 13,00  1,49 kg. Os cordeiros foram distribuÃdos em delineamento inteiramente casualizado em arranjo fatorial 3x2 (nÃvel de restriÃÃo x classe sexual), de acordo com a quantidade de alimento fornecida. A duraÃÃo do experimento foi determinada pelo tempo necessÃrio para que a mÃdia de peso corporal dos animais de um dos tratamentos atingisse 28 kg, ocasiÃo em que todos os 30 animais foram abatidos. NÃo houve interaÃÃo significativa entre os nÃveis de restriÃÃo e a classe sexual para Ãrea de olho de lombo (AOL), espessura de gordura subcutÃnea (EGS), profundidade do Longissimus dorsi na lombar (PLDL) e espessura de gordura subcutÃnea na lombar (EGSL) no momento do abate. Possivelmente, devido à reduÃÃo na oferta do alimento, a AOL, a EGS, a PLDL e a EGSL apresentaram valores mÃdios reduzidos em funÃÃo do aumento no nÃvel de restriÃÃo alimentar. Houve interaÃÃo entre os nÃveis de restriÃÃo alimentar e as datas de mensuraÃÃo para AOL, EGS, PLDL e EGSL. Foram observadas correlaÃÃes significativas entre as caracterÃsticas in vivo e as caracterÃsticas de carcaÃa. A AOL por ultrassonografia in vivo foi altamente correlacionada com a medida desta variÃvel na carcaÃa, demonstrando a eficiÃncia do mÃtodo. Houve interaÃÃo entre os nÃveis de restriÃÃo alimentar e as classes sexuais para as variÃveis intensidade de amarelo e pH no mÃsculo Longissimus lumborum e para forÃa de cisalhamento no mÃsculo Semimembranosus. Para os animais nÃo castrados, a intensidade de amarelo foi maior para o nÃvel de 30% de restriÃÃo no mÃsculo Longissimus lumborum. NÃo houve interaÃÃo significativa entre os nÃveis de restriÃÃo e a classe sexual para os aspectos de qualidade relacionados à saturaÃÃo de cor, tonalidade da cor, luminosidade, intensidade de vermelho, capacidade de retenÃÃo de Ãgua e perda de peso por cocÃÃo para os mÃsculos Longissimus lumborum e Semimembranosus. Cordeiros Santa InÃs submetidos à restriÃÃo alimentar apresentam menores valores para AOL, EGS, PLDL e EGSL, sendo estas avaliadas in vivo. Embora a restriÃÃo alimentar e a classe sexual tenham influenciado as variÃveis relacionadas à qualidade da carne dos animais avaliados, os valores mÃdios observados sÃo considerados aceitÃveis pela literatura. Os nÃveis de restriÃÃo alimentar e a classe sexual influenciaram algumas caracterÃsticas importantes da qualidade da carne de cordeiros Santa InÃs. / The objective of the present study to evaluate the use of ultrasound and quality lamb meat Santa InÃs of different sex class subjected to food restriction. Were used thirty Santa InÃs lambs, 15 castrated and 15 nonâcastrated, with approximately two months of age and initial body weight in average of 13  1.49 kg. The lambs were assigned to a completely randomized design in a 3x2 factorial arrangement (levels of feed restriction x sex class), according to the amount of food provided. Experiment period was determined based in the time required for the animals one of the groups achieved 28 kg of body weight in average, when all 30 animals were slaughtered. There was no significant interaction between restriction levels and sexual class to rib eye area (REA), subcutaneous fat thickness (SFT), depth of Longissimus dorsi in the lumbar (DLDL) and thickness of subcutaneous fat in the lumbar (TSFL) at slaughter. Possibly due reduction in food supply, the REA, the SFT, the DLDL and The TSFL showed average values reduced in function increase levels of feed restriction. There was interaction between levels of feed restriction and the measurement dates to REA, SFT, DLDL and TSFL. Significant correlations were observed between the in vivo characteristics and carcass characteristics. The REA by ultrasound in vivo was highly correlated with the measure of this variable in the carcass, demonstrating its efficacy. There was interaction between levels of feed restriction and sex classs for the variables intensity of yellow and pH in Longissimus lumborum and shear force in Semimembranosus muscle. To animals non-castrated, the intensity of yellow was higher with 30% restriction on the Longissimus lumborum. There was no significant interaction between restriction levels and sexual class to quality aspects related to color saturation, color tone, luminosity, red intensity, water retention capacity and weight loss for cooking for Longissimus lumborum and Semimembranosus muscles. Santa Ines lambs subjected to food restriction have lower values for REA, SFT, DLDL and TSFL, which are valued in vivo. Although feed restriction and sexual class have influenced the variables related to the meat quality of animals evaluated, the mean values observed are considered acceptable in the literature. The food restriction levels and sexual class influenced some important features of meat quality Santa Ines lamb.

Methods of the work: pansy biometric parameters were measured using the methodology by J. Vaidelys (2005). Measurements were carried out on 20th April. When plants reached the flowering stage (BBCH 60 - 65) during which assessment of pansy size of flowers, and the stalks lengths, seedling height and diameter, calculated the number of flower buds and leaves and set the beginning of flowering.
The results of the work: growth regulator CCC, had an impact on pansy’s (Viola x witrockiana Gams) seedling quality parameters. Increasing the concentration of the solution (0,15%, 0,30%, 0,45%), amount of leaves and buds increasing trend. Different concentrations were significantly reduced pansy seedling height, stalk length and diameter of the plant, but did not affected the flower size. The biggest impact was 0,45 % concentration of the solution. Reliably produced the most leaves, pansy, which watered every 14 days compared with the control treatment. Flowering time was much influenced by watering every 14 days with the highest concentration of a solution, while the earliest flowering started when pansy was spray every 7 days with 0,15 % CCC solution.

Odrůdová kvalita sladovnického ječmene / Varietal quality of malting barleyKADLECOVÁ, Helena January 2015 (has links)
By purchasing malting barley the quality is evaluated according to standards, techniques, laboratory methods and qualitative indicators, which are set by norm. Evaluation of quality of barleycorn as a material for producing malt is used for setting the price, observing changes of the quality during storing etc. There were evaluated qualitative indicators of 13 sorts of malting barley, which were bought by company ZZN Pelhřimov between 2010-2014 from farmers, agricaltural cooperatives and companies and also self-employed farmers from the region Vysočina. These sorts were represented by different number of samples in connection with bought-up amount and number of supplies of each sort. Weighted averages were counted from results. Average figures of results of analysis were compared with the national average. Research institute of brewer´s and orchardist a.s. in Brno deals with monitoring of quality of malting barley in the Czech Republic and it evaluates annually ca. 500 harvest samples which were received by producers from all regions in the Czech Republic. The quality of malting barley showed a big variability in all parameters across all types and also in particular years. Malting quality is influenced by many factors especially by course of weather in each particular year. Limiting parameter of quality by purchasing malting barley was N- substances content in barleycorn. Germination capacity seems to be the most stable from all parameters. Lower figures of germination capacity were found only by winter types in connection with longer period of ripening after harvest.

Impact of Quantitative and Qualitative Parameters on Stock Performance / Påverkan kvantitativa respektive kvalitativa parametrar har på aktiemarknadens utvecklingNivre, Fredrik, Sjöbohm, Martin January 2022 (has links)
Stocks belonging to publicly traded companies is a topic which in society is mystified and by some considered to be an unpredictable phenomenon where you either make an economic loss or gain seemingly by chance. Despite this, there are numerous fields of work where the sole purpose is to predict the movement of stocks in order to maximize economic gain. The purpose of this report was to research whether or not these movements actually can be predicted by the usage of regression analysis. A regression model was constructed where the response variable used was the rate of change of a certain stock over 30 days and numerous different qualitative and quantitative parameters were used as regressors. This full model was then evaluated and improved in order to refine its construction and results yielded in order to present the best possible model. When researching and optimizing the model, it was found that several parameters turned out to be statistically significant for the model. The model itself did however come with some uncertainties in the form of a low R-squared value, meaning that despite the significance of said parameters, it contained a high amount of unrepresented variance. / Aktier tillhörande publikt handlade bolag är i samhället ett mystifierat ämne varvid vissa ser det som ett oförutsägbart fenomen, som kan genera antingen vinst eller förlust, till synes av slumpen. Trots detta finns det flertalet områden vars främsta syfte är att förutspå aktiers prisrörelser med ändamålet att maximera ekonomisk vinning. Syftet med denna rapporten var att studera huruvida dessa prisrörelser faktiskt kan förutspås med hjälp av regressionsanalys. En regressionsmodell skapades där rate of change för flertalet aktier under en period på 30 dagar användes som responsvariabel. Flertalet olika kvantitativa och kvalitativa parametrar för respektive aktie användes som regressorer. Den fullständiga modellen som byggde på all data utvärderades för att sedan förbättras, i syfte att förfina dess uppbyggnad och de resultat den genererade, för att skapa en så bra modell som möjligt. När modellen studerades och optimerades kunde det konstateras att flertalet parametrar var statistiskt signifikanta för modellen. Modellen hade dock osäkerheter i form av bland annat lågt R-kvadratvärde, vilket innebar att trots statistiskt signifikans i flertalet parametrar, kunde modellen inte förklara en stor del av förekommen varians.
