Buřičová, Karolína January 2022 (has links)
The work is devoted to new possibilities for the recovery of secondary raw materials and track bed waste with a combination of both suitable and unsuitable soils. The aim of the thesis is to develop a new functional sample suitable for the recovery of a substructure of railways based on secondary raw materials. The theoretical part addresses the issue of the use of soil and secondary raw materials as the base layers of railway structures, and is focused on the possibilities of soil adjustments or enhancement. The practical part is focused on the analysis and selection of potentially suitable raw materials, the design of new raw material mixtures containing concrete recyclables, waste from cleaning the auto mixer and waste from cleaning the rail bed. Further, to modify the mixtures designed with fluid ash from biomass combustion to achieve higher toughness. Then they will be experimentally verified and based on the results the optimal formula for use in the solid of the railway bottom will be determined. Final optimal recipe achieving basic required parameters for use in active zone without the requirement for frost resistance and ecology is composed of 30 % of F4-CS, 4 % of portland cement CEM II-B/LL, 3 % of lime hydrate, 70 % of recycled concrete and 10 % of fluid ash from biomass combustion.

Čížková, Karolína January 2015 (has links)
This thesis examines the influence of active exercise according to the concept of the Dynamic Neuromuscular Stabilization on local sensory perception in the mid-thoracic spine in elite athletes - cross-country skiers. It also describes the most common health problems in these athletes and assesses the impact of the integration of active exercise according to the DNS concept into everyday practice of cross-country skiers on the intensity and frequency of pain in cervical, thoracic and lumbar spine. It also presents theoretical knowledge about the concept of the Dynamic Neuromuscular Stabilization and interdependence of quality of sensory and motor functions. Methods: The study included a total of 20 elite athletes - cross-country skiers aged 17- 27, randomly divided into two groups. The training group integrated into their practice selected three exercises according to the Dynamic Neuromuscular Stabilization targeting segmental motion in the thoracic spine. A total of five measurements were performed on the quality of sensory perception during two months for all athletes. Furthermore, we evaluated the immediate effect of the therapy in the test group through the examination of sensory perception before and immediately after the treatment. At the beginning and at the end of the study each athlete...

Efekt konceptu DNS u pacientů s chronickým vertebrogenním syndromem bederní páteře / The effect of the cencept of DNS in patients with chronic vertebrogenic syndrome of lumbar spire

Šulová, Eva January 2014 (has links)
The main aim of the presented diploma thesis was to record objective and subjective changes after therapy with DNS concept in a group of 13 people with LBP. Moiré projection topography was used to record postural changes after 5.5 week therapeutic intervention. It was not clear, whether DNS exercise would help them to achieve visible postural changes and whether this technique is able to record these changes, which would mean that it is a suitable option for objectivisation of therapies focusing on correction of stabilisation and postural functions. Pedoscan was used for further objectivisation of the effect of DNS concept. The chosen correlate of the mentioned objective evaluation was Oswestry disability index, evaluating limitations of common everyday activities resulting from pain in the lower back, and the Numeric pain scale. Patients underwent 5 hour-long physiotherapeutic lessons, the recommended frequency of exercises in the household environment was 3-4 times per day. The probands exercised with the use of DNS concept according to the individual examination findings, especially in the area of the integrated spine stabilisation system. The data were statistically elaborated by Wilcoxon Signed-Rand test, which a non-parametric variant of the pair T-test. It is obvious from the results that...

Burešová, Vendula January 2015 (has links)
The main target of this thesis was to detect objective changes in the implementation of four postural locomotor tests DNS and during walking. The movements were recorded using the optical MoCap - the kinematic analysis Qualisys. The particular interest of the investigation was to determine the current stabilization of the spine system in individual subjects aged 25 to 55 years, which was documented by means of the angular deflection of each segment, the flat segment deviation or the shift of the marker in a coordinate system. The measurement results were compared between ten individuals with LBP and ten persons without any difficulty who were placed into the control group. The data were collected using the software QTM and Visual3D and subsequently were statistically processed. A statistically significant difference was observed during walking when comparing the angular deflection of the pelvis to the chest at the rotation and lateroflexion (ř). The significant difference of the pelvis shift toward the chest during flexion and rotation (ř) was showed in a deep squat test, but the difference was not confirmed in lateroflexion (ř). Furthermore, no statistical difference of the lateral deflection of the same segment (pelvis or chest) (cm) in patients with LBP compared to all subjects during the...
