Negative effects of high temperatures on cattle milk production is a specific problem. Dairy-cows, who produce much more heat than cows that are not milked, are more susceptible to high temperatures of the surrounding environment than other cattle. Changes in temperatures and atmospheric pressure were monitored throughout a year and then its influence on the milk production of cattle has been evaluated. It has been discovered that low temperatures do not have any significant influence on dairy-cows. However, at high temperatures dairy-cows suffer from heat stress and it leads to lower volumes of the daily milk production. The Holstein breed showed a higher sensitivity to temperature fluctuations than the Czech spotted breed; however, the Holstein breed milk production is better balanced in a long run (a year period).

The final thesis analyzes the influence of high temperatures on the quality of the glued joints glued with hotmelt polyurethane adhesive. The panels of particle board were finished with ABS edge by using modern technology for edgebanding. The samples were tested in peel test performed at an angle of 90° and shear under compression loading at an angle of 45°. The experiment was carried out for samples stored in standard conditions and samples placed in conditions simulating the internal environment in standardized transport units in intermodal transport. Results were compared with each other, they were also compared with the results for the glued joints with hotmelt ethylene vinyl acetate adhesive.

Jiří Ptáček Title of the diploma thesis: Influence of cycling movement of lower extremities on changes in blood pressure and pulse repetition frequency Department: Department of physiotherapy Supervisor: doc. MUDr. Jiří Kříž, Ph.D. The year of presentation: 2018 Abstract: Due to permanent neurological impairment, patients with spinal cord injury (SCI) are put at risk of complications caused by immobility such as ischemic heart diseases, obesity and metabolic syndrome, which again increases their morbidity and mortality. Based on recent studies, passive cycling (PC) could have protective influence on SCI patients' cardiovascular system. The objective of this thesis is to verify whether PC will effect a change in heart rate and blood pressure in SCI patients and whether or not this reaction depends on the position of spinal cord injury, and hence on intact sympathetic innervation (the line was drawn at Th6 - below and above) 17 patients of Special Unit at Motol...

Whereas the effects of a long-term activity of head-down tilt (HDT) in the angle between 3ř and 12ř were examined in details in cosmic medicine as the model of a state of weightlessness, literature concerning effect of HDT on cardiovascular control in the angle over 30ř is scarce. The aim of the thesis is to examine acute reaction of systolic, diastolic, mean arterial blood pressure and heart rate during three minutes of 30ř, 50ř and 70ř HDT, realized on a tilt (inversion) table with fixed legs. For the combination of HDT and head-up tilt (HUT), the following protocol was chosen: 5 minutes lying in a horizontal position (HOR), 3 minutes of 70ř HUT, 3 minutes of 30ř HDT, 3 minutes of HOR, 3 minutes of 50ř HDT, 3 minutes HOR, 3 minutes of 70ř HDT, 3 minutes HOR and 3 minutes of 70ř HUT. A non-invasive continuous Peňáz method, using Finapres Ohmeda, was used to monitor beat-by-beat blood pressure and heart rate. Blood pressure was also measured by sphygmomanometer each minute for calibration. In the angle of 30ř HDT, there was a significant decline of heart frequency (p < 0,01). During the 50ř HDT, there was a significant rise of systolic blood pressure in the third minute, of diastolic and mean arterial pressure each minute and the heart rate dropped significantly (all p < 0.05). In the 70ř HDT,...

In my thesis I'll focus on one of three disciplines in powerlifting. Specifically bench press. Aim of this thesis is confirmation of Smolov jr. training plan. Which is different from other training plans thanks to it's short term. Lasting only three weeks. Despite that I was able to find multiple articles, in which the author describes his own experience, introduces reader with the training plan and reports progress up to 10 Kg in the discipline. The research will be conducted by direct testing of the plan on a group of probands, including me. The resoult of which will be comparing of input and output values - like bodyweight, chest and arms circumference and of course maximal bench press performance per one repetition. The thesis will also include important information about bench-press as a sport, informations about diet, food supplements, regeneration and anatomy. Powered by TCPDF (www.tcpdf.org)

The aim of this work is to describe final properties of the electrodes based on the amount of pressure used during its production. In the theoretical part of this work, secondary electrochemical accumulators are described, with the focus on Li-ion accumulators. In the main part of this work, the production of Li-ion accumulators, with usage of different pressures during its production is described. In the final part of this work, the examination of these created cells for the classification of the optimal production pressure is described.

In this master’s thesis there is firstly conducted research about pressure measurement. Next there is mathematical description of thermodynamic conditions in used testing chamber by using magnetohydrodynamic and Maxwell equations. Next chapter deals with testing chamber itself, more precisely with function, model and changes done to it. In practical part there are data measured by used sensors, which are also closer described in this chapter. In next chapter there is comparison of reaction times of used sensors and their frequency specters, obtaining using fast Fourier transformation. Second to last chapter introduces very measurement on the real device and in the last chapter these data are analyzed and more closely described.

This thesis is focused on the optimization of pressure conditions in the water supply network. There is a deep theoretical and critical search of the state of the art and there are fields where there is an insufficient field of knowledge, the so-called "knowledge gap". Experiments are proposed here to determine the dependence of water consumption on pressure conditions. There is a description of experiments and way how it was carried out, which were carried out on the water connection, in the pressure zone and in the laboratory on the hydraulic loop. There is proposed a methodology of experimental determination of the mathematical dependence of water consumption on pressure so that it can be used for optimization problems, where consumption is considered as an optimization criterion. The results of individual experiments are evaluated and a critical discussion of the achieved results is carried out. Finally, the achieved results are compared with the values found in a deep literature search.

This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.

This paper deals with production of the structures fabricated using low temperature co-fired ceramics. Focus is on the lamination of raw ceramic tapes. There are presented classical thermo-compressive methods and a new method using chemical solutions for tape bonding. Describes new lamination technology and their advantages are the absence of elevated temperatures and high pressures. This method reduces using of higher temperatures and high pressure during lamination. On the other hand, chemical process of tape bonding is not flawless. There are many problems including solvent deposition, extreme sensitivity to dust and other processing parameters. It also describes the fabrication of structures by chemical way. Specifically, analyzes the method Cold Chemical Lamination and provides examples of possible deposition solvents which are needed for etching the surface of the LTCC tape during the lamination.
