Fixace těžkých kovů v cementové matrici s příměsí přírodního zeolitu / Immobilization of heavy metals in the cement matrix with the admixture of natural zeolite

Semerádová, Nikol January 2017 (has links)
Heavy metals released to the natural ecosystem constitute significant risks not only for organisms, but also for water supplies in the nature. There are a number of analytical methods for the determination of heavy metals. Each of them is suitable for different element and its character. Since the results of the analysis are applied during the solidification and stabilization, it is necessary to ensure the highest correlation between hazardous waste and solidification medium for maximum inhibition of toxic ions. This work investigates the stabilization of heavy metals binders based on cement base with admixture of the natural zeolite and its possible use for the solidification of heavy metals in soluble form.

Objektivizace léčebných metod v oblasti hlubokého stabilizačního systému páteře / The objectification of therapeutical methods used for improvement of the deep stabilizng spinal system

Malátová, Renata January 2009 (has links)
5 Summary So far, no commercially used device, capable of evaluating the condition of the deep stabilizing spine system (DSSS), has appeared on the market. Therefore, a so called muscle dynamometer (SD01, SD02), has been constructed that enables to reveal a possible dysfunction of the DSSS. During a six-week-rehabilitation-course, aimed at correcting the body posture and strengthening the DSSS muscles, a statistically significant change (p<0.001) between the values of input and output measurements of the chosen group tested has been obtained. Correctness of the approach to objectify the initial state of the patient and his progress during the treatment was shown by the completed measurements. The effectiveness of therapeutical training was confirmed. Based on positive experience from SD01, a new version of muscle dynamometer, SD02, was constructed. Measurements by SD02 were to establish the condition of DSSS (frontal spine stabilization) by a lay-sit test repeatedly from the test battery UNIFITTEST 6-60 and by the diaphragm test. Measurements were conducted on 45 samples. Basic somatic measurements were performed and then measurements with the SD02 were conducted during the diaphragm test and UNIFITTEST. For comparison of the values the pairing t-test was used (normal data distribution was verified by the...

Kamarýtová, Jitka January 2016 (has links)
1 Abstract Title: Exploitation of regular exercise based on the elements of developmental kinesiology for people suffering with back pain. Objectives: The aim of my diploma thesis was observing the effect of a group motional program based on tenets of developmental kinesiology for function of the motional system of clients suffering from back pain. Methods: The theoretical part of my diploma thesis was done with a method of literary recherché using technical literature, articles and studies. Experiment was chosen for the practical part, quasi in particular, which was complemented by method of qualitative research, personal case study in particular. There are two clinical casuistries paced in my thesis. There were two following methods for collecting data during my research: kinesiology analysis focused on anamnesis, check-up by sight, check-up by touch and functional probing (dynamic check-up of spine, diagnostically testing of deep stabilizing muscles.) Another methods used in my diploma thesis were assessments of pain with a usage of visual analogy scale and semi-structured interview. Pre-tests and post-test were identical. 10 people suffering from chronic back pain in an area of cervical spine or lumbar spine (5 clients suffering from chronic back pain in an area of lumbar spine and 5 clients suffering...

Korigovaný vis jako kompenzační prvek ve fyzioterapii / Corrected hanging up as compensation mode in physiotherapy

Waldmann, Tadeáš January 2017 (has links)
Title: Corrected arm hang as a compensatory element in physioterapy Objective: The main objective of this master thesis is to measure and compare the level of engagement of muscles stabilizing the scapula during arm hang and supported exercise. Methods: Our study included nine probands whose measurement results were evaluated quantitatively. The age of probands at the time of measurement was from 18 to 25 years. A condition for inclusion in the investigated group was absence of subjective symptoms, functional impairment, traumatic injury, orthopedic defects or diseases of the upper limb. All probands were active athletes. Biomonitor ME 6000 manufacturer Mega Electronics Ltd. was used for recording the electrical activity of the muscles. The obtained data were processed by the Megawin software. All measurements for the purposes of the study took place in the laboratory of biomechanics FTVS UK. The resulting data were compared intraindividual and interindividual. Results: The results demonstrated that middle and lower portions of m. Trapezius is more active in the corrected arm hang. In contrast, the supported exercise leads to greater activity of m. Serratus anterior and lower activity of upper portion of m. Trapezius. Keywords: arm hang, supported exercise, surface electromyography, stabilization...

Zasadilová, Anežka January 2020 (has links)
Author: Bc. Anežka Zasadilová Title: The effect of physiotherapy on patients with gastroesophageal reflux disease Objectives: The aim of this thesis is to design a therapeutic unit and evaluate its effect on long-term treatment in the therapy of selected patients with gastroesophageal reflux disease Methods: The group of patients treated for esophageal reflux disease was examined using a standardized questionnaire, esophageal manometry and postural tests. This was followed by a two-month therapy aimed at stretching and strengthening the diaphragm using several physiotherapeutic methods. After completing the therapy, the probands were measured again as in the same way as in the initial examination. The obtained data were evaluated by statistical analysis using a nonparametric test for one selection (Wilcoxon test). Results: The evaluation of the questionnaire survey resulted in the value of p-value = 0.007265, ie less than the selected level of alpha significance (= 0.05). Based on the Wilcoxon test, it was confirmed that the input score was statistically significantly higher than the output score. The evaluation of the esophageal manometry gave the value of p-value = 0.6956, ie greater than the selected level of significance alpha (= 0.05). Based on the Wilcoxon test, it was not confirmed that the...
