Burgová, Jana January 2013 (has links)
In the years 2008 - 2010 was realized trials with goal to influence the properties of the growing medium so, as the internal and external quality model plant (Viburnum opulus L.) grown in containers was significant increase. The whole of experiment was annually divided into equally two blocks, with different irrigation rates, which were also observed micro--climatic parameters both irrigation regimes. Was studied as well the influence of addition of soil conditioners on the properties of the growing medium. External quality of grown plants was assessed on the basis of morphological parameters (plant height, number of shoots, root collar diameter, dry matter of above-ground and root zone of plants and visual assessment of the root system) and internal quality based on the evaluation of physiological parameters (stomatal conductivity, chlorophyll fluorescence and chlorophyll content in the leaves). From the soil conditioners was investigated the impact of three commercially available agents with different composition and mode of action. It was a Hydrogel, TerraCottem and Agrosil LR. The properties of the growing medium, was affected by soil conditioners additive into the growing medium (peat--bark medium RKS II), but not enough for increase the quantitative parameters of cultivated plants, even the selected parameters in comparison with the control variant in both irrigation regimes were positively influenced, in order Hydrogel, Agrosil LR and TerraCottem

Vyhodnocení úspěšnosti sportovních plemen koní ve skokových soutěžích v České republice

Horká, Marie January 2016 (has links)
The aim of the study was evaluate sporting breeds of horses used for show jumping sport in the Czech Republic. In the literary section is describes the show jumping sport, history of show jumping sport and characterization of the breeds which are used in the Czech Republic and worldwide in the show jumping sport. The work insludes statistical evaluation of the effect breed on the performance of the horses. Performance is evaluated by the auxiliary points PPB to one start. Auxiliary points expressed the preformance of the horses. The points are calculeted according to the real resulsts in the competitions in the criminal points. The criminal points are converted to the auxiliary points. Data was used from the Summary of sport horses of 1995, 2005 and 2014, issued by the Czech Equestrian Federation. Data was further processed and statistically analyzed. Statistical conclusiveness of the breed on the performance was confirmed, in some cases it is also highly statistically conclusive. Breeds were further tested to determine which breed is the most performance and the most appropriate for show jumping sport. In the 1995 it was found, that the most performance for show jumping sport of the ranking top 300 horses are germans warmblood breeds with 6,25 PPB. In the 2005 was the most performance breed hanoverian horse with 8,30 PPB. In the 2014, besides germans warmblood breeds with average value of 8,28 PPB come to the foreground other warmblood breeds with 9,44 PPB and breeds like belgian warmblood with 8,07 PPB and holland warmblood with 7,75 PPB. In the statistics of all started horses in the 2014 was the most performance breed belgian warmblood with a value of 8,81 PPB. Statistically conclusiveness effect on performance was found also for sex. When the most performance are stallions with 4,56 PPB, then mares with 3,91 PPB and the geldings with 3,75 PPB are least performance.

1 Abstract Charles University in Prague, Faculty of Pharmacy in Hradci Králové Department of: Departmanet of Pharmaceutical technology Consultant: doc. PharmDr. Zdeňka Šklubalová Ph.D. Student: Hana Machutková Title of Thesis: Influence of different types and ratios of microcrystalline cellulose and lactose on physical properties of tablet blends and tablets. In this study, the properties of tablet blends prepared from five different kinds of microcrystalline cellulose (Avicel ® A-101, 102, 105, 112, 200) and three types of lactose in different proportions were evaluated. Moisture content, the bulk and tapped density and the angle of repose were compared for tablet blends. The addition of lactose to the mixtures caused the decrease in the moisture content in the tablet blends. After evaluating the flow properties, the mixtures with suitable characteristics were compacted at compression forces of 8 and 12 kN. The force required to eject the tablet, the table strength, the disintegration time and the friability of the resulting tablets were estimated. The worst compressibility was identified for mixtures with higher concentration of Avicel 105. Due to its very small and fine particles (approximately 20μm) the filling of matrix was not uniform making tablet compression unsuccessful and thus the of uniform...
