The aim of the diploma thesis is to determine the influence of using a agri-tractor in agriculture and its impact on the environment of sandy loam soil. The influence on the pedocompact is compared when using different mechanization under operating conditi-ons. A tractor with semi-trailer and TATRA agri-tractor with semi-trailer were used for that purpose. The main point of the work is a field-laboratory experiment, on the basis of which the influence of transitions of individual ensembles on the soil is evaluated. The experi-ment was carried out in 2015 on the land farm cultivate by Agrodružstvo Blížkovice. Key indicators of soil compaction were appraised during the experiment. Within the literary research soil itself is characterized in general, as well as the issues of soil compaction and various types of transport in agriculture. The experimental part includes the methodology used, the material researched together with the measurement results and further discussion on the topic. Transport operations represent more than 50 % of the total agricultural output volu-me. Along with the intensification of agriculture and simultaneous magnification of ag-ricultural technology the problem of excessive soil compaction had begun to deepen. The soil compaction negatively affects the physical and chemical caharcteristics of soil and reduces its fertility. Agricultural equipment manufacturers have been trying to develop new mechani-zation technologies to minimize soil compaction. Considering soil compaction, the use of a tractor with semi-trailer has appeared as more suitable. Appropriate solution seems to be using special central tire inflation system or in contrast different ways of their underinflation.

Title: Biomechanical aspects of the dynamics of intracranial pressure in traumatic brain injury Author: Ing. Martin Mayer e-mail: mayercz@seznam.cz Department: Department of Anatomy and Biomechanics Supervisor: doc. PaedDr. Karel Jelen, CSc. This PhD thesis "Biomechanical aspects of the dynamics of intracranial pressure in traumatic brain injury" is about the dynamics of intracranial pressure, particularly in relation to the external mechanical action of the patient. Severe head injury is the leading cause of death in patients under 35 years of age. Despite constantly-improving medical and nursing care only one third of patients, after recovery, regained the ability to live independently in the long term. Two-thirds of patients were severely disabled or died. The lifetime cost of such a patient who was not completely cured has been calculated to be $4,000,000. A significant consequence of craniocerebral injuries are secondary brain lesions, which among other means the rise in intracranial pressure (ICP), which can further exacerbate due to intracerebral or extracerebral causes. Therefore, the objective of the treatment is minimizing secondary injury, optimally at the phase of the primary lesion. However, realization of this requirement, about which we can say that is a conditio sine qua non, sometimes leads...

Introduction - This thesis focuses on the reaction of cardiovascular system to Lokomat therapy in patients with lesion of the spinal cord. It observes reaction of the heart rate and systolic blood pressure and compares with the cardiovascular response to the exercise on an upper body ergometer. Methods - We recruited 25 patients with spinal cord lesion under Th 5 and 4 patients with lesion above Th 5. The blood pressure was measured. The heart rate was measured by by ambulatory blood pressure monitor and an auscultatory method using a mercury manometer and a stethoscope a sporttester. Patients were measured during the Locomat therapy and the exercise on an upper body ergometer during the 6-minute arm test. Results - The parameters of systolic blood pressure and heart rate had a tendency to increase with the peak in 25th minute of the therapy. There was no significant difference between the patients with lesion under or above Th5. The parameters of heart rate were significantly higher on the upper body ergometer than on Lokomat. Conclusion - The Lokomat therapy does have a positive influence to cardiovascular system of patients with complete or incomplete spinal cord injury. When using this approach, the most important benefit is the possibility to activate all parts of body. Keywords: spinal cord injury,...

Title of thesis: Influence of intra-abdominal pressure on the stability of the lumbar spine Definition of the problem: This thesis addresses the problem of the stabilization mechanism of the lumbar spine and the influence of intra-abdominal pressure on the stability of the lumbar spine. Objectives: The aim of my thesis is to locate, evaluate and process all available resources and to bring up the issue of IAP and its influence on the lumbar spine. The work should provide the widest possible insight into the problems of IAP effects on the stability of the lumbar spine, summarize differing opinions, and allow easier orientation in the isme. Method: The work is treated as a search, focusing on the processing and retrieval of literature concerning the issue. Studies included range from 1953 to present. To which I will use a variety of sources of literature, internet and consultation with the head of my thesis. Results: The increase in IAP, which is provided by a synchronous contraction of the diaphragm, pelvic floor muscles and m. transversus abdominis, can effectively stabilize the spine. But you can not determine with certainty whether this mechanism to support the stability of the lumbar spine is indeed used or the stability is provided by contraction of muscles, leading to an increase in IAP, and...

Elastic sculpture - Cylinders Each object is created from men´s deodorant (spray) and silicone rubber. Shape and scale of the object depends on a size of spray which is cast in the geometric shape. Inflating the object by compression on the top part makes fast deformation or destruction. Instalation include 5-10 objects.

Problem: Running is one of the most widespread physical activities. Incorrect running technique, training quantity but also the runner's equipment can strongly affect health condition of the individual, both positively and negatively. For that reason various trends emerge in the area of running footwear. They include classical sports shoes with different types of impact attenuation as well as the minimalist footwear made to imitate barefoot running, which should be much more natural for humans, as insisted by B. Nigg in his book "Born to Run" - where he says that man was born to walk and run barefooted. Inappropriate shoes can cause various health complications, not only in the foot area. Objective: To find out how foot strike changes in the area of the foot-shoe interaction in running on flat ground when an amateur runner uses minimalist and sports footwear and to draw conclusions for training practice on the basis of the results. Methods: The thesis deals with amateur endurance running in different shoe types (minimalist and sports shoes). The study specimen consisted of 14 female runners (mean body weight 63,31 ± 4,89 kg, height 169,69 ± 4,71 cm, age 31,92 ± 5,34 years, speed in minimalist shoes (MO) 3,34 ± 0,06 m.s- 1 , speed in sports shoes (SO) 3,29 ± 0,06 m.s-1 , weekly mileage 37,54 ± 9,43...

Dissertation focuses on the influence of selected factors on the properties of the bond glued by acetate polyvinyl adhesives. Factors such temperature and moisture content of the environment, the pressing pressure and cyclic stress. Despite the same type of adhesive, the properties may vary for different producers of adhesives and according to which the product is not intended. Influence will be compared to the test samples of dried beech timber with regard to shear bond strength. They will be compared properties of adhesives from different manufacturers and different destination. Test samples and test progress carried out in accordance with current standards, or largely based on. This research should help users streamline the process of adhesive bonding and reduce the production costs of the bond.

This thesis deals with the description of particular types of motorcars´ drives, it especially handles with engineering solution of one or both of axels. In this thesis there are described power dissipations impacting moving vehicle. These power dissipations are needed to be overcome. In the practical part of the thesis the thesis deals with measuring of power dissipations of a one drive or all drive vehicle. Another point of measurement focuses on tire pressure rating and its impact on the power dissipations. All measurements were realized according to descibed methodology.
