Sliding and Lifting Platform
Kučo, Stanislav ; Suchomel, Petr (referee) ; Škopán, Miroslav (advisor)
This thesis describes a project of a mobile stage device that will be used for a concert tour of Lucie. The first part characterizes the given task and expounds description and function of the device itself. The second part focuses on the design concept of supporting frames. This is followed by design and calculation of all mechanisms, actuators and construction of individual moving parts of a sliding and lifting platform. The last part verifies stability of the whole construction in accordance with appropriate standards. The thesis also contains technical documentation, which is to be found in appendix.

Electromechanical alternative of linear hydraulic tractive unit
Hammer, Jaroslav ; Suchomel, Petr (referee) ; Kašpárek, Jaroslav (advisor)
In this diploma thesis is accomplished description of existing condition of decorating linear tractive unit. Analysis of safety requirements for linear tractive unit is also accomplished. Eligible construction concept of frame of electromechanical linear tractive unit is chosen. Selection and calculation of ball screw and nut is made also with draft of its eligible support . Choose of eligible engine and clutch for gearing of engine torque from engine to the ball screw is done too. Further is designed eligible concept of gearing of the rotary motion of ball screw to straight motion of bottom pulley block, which now interacting with upper firm pulley block provides lifting of tensile rod with coulisse.

Church autonomy in the Czech Republic as an expression of religious freedom and its legal limits
Suchomel, Petr ; Gerloch, Aleš (advisor) ; Řepa, Karel (referee)
The thesis title The church autonomy in the Czech Republic as an expression of freedom of religion and its legal limits ABSTRACT The rigorous thesis deals with the constitutionally guaranteed autonomy of churches and religious societies as one of the essential elements of freedom of religion. It examines what is necessary content of it and seeks the highest permissible limits of its legal restriction in a democratic state governed by the rule of law (in general) and in the Czech Republic (in particular). It represents the autonomy of churches and religious societies as an integral part of religious freedom, which is an inalienable human right and freedom. The general part of the thesis analyzes the content of freedom of religion and the content of church autonomy, trying to define its maximum limits, especially through the development of constitutional law in individual European states (by comparing their constitutions) and through the abundant judicature of the European Court of Human Rights. The special part of the thesis deals with the development of freedom of religion and church autonomy in the territory of the Czech Republic since reception of Austrian law in former Czechoslovakia during the First Republic, through the "period of darkness" under communist totalitarianism to the present day.

Skull Base Meningiomas
May, Michaela ; Beneš, Vladimír (advisor) ; Smrčka, Martin (referee) ; Suchomel, Petr (referee)
This dissertation is a set of 5 studies focused on skull base meningiomas. The anatomical study explored the dislocation of the outer and inner arachnoid membranes by the skull base meningiomas. The findings can be applied during surgical resection to predict the presence or absence of the arachnoid dissection plane and the adherence of critical neurovascular structures. The Czech multicentric study documented overall survival 98.1 %, morbidity 13.2 %, and mortality 1.3 %. Predictive factors of histological grade, the extent of resection, clinical outcomes, risk of recurrence and progression were analyzed. Petroclival meningiomas originating within the interpeduncular and prepontine cisterns were the most surgically challenging. Our prospective study focused on the examination of olfaction in olfactory groove meningiomas. The predictors of olfaction preservation were intact olfaction, lower volume and unilateral surgical approach. Olfaction examination is essential to choose surgical strategy and evaluate functional outcome. In a retrospective study of Simpson grade IV resections, adjuvant stereotactic radiosurgery was associated with longer progression-free survival, time-to- progression, and overall survival. Due to the high percentage of progressions (50 %) and the long overall survival (10...

Cervical spondylotic myelopathy: development of clinical symptoms and surgical management
Štěpánek, David ; Choc, Milan (advisor) ; Suchomel, Petr (referee) ; Ostrý, Svatopluk (referee)
Based on contemporary theoretical knowledge in this prospective study we outline the relationship between a chosen surgical approach (anterior or posterior approach) as it relates to the localization of spinal cord lesion (anterior or posterior spinal pathways) assessed by the use of evoked potentials (SEP, MEP) and the effect of this approach on the postoperative state of patients with cervical spondylotic myelopathy. Furthermore we evaluate clinical outcome of these patients according to several aspects of their MRI and X-ray findings. The study, from 2006 to 2010, comprised 65 patients with clinical signs of cervical myelopathy. These patients had been indicated for surgery, which subsequently was performed by using either the front (anterior - a) or back (posterior - p) approach. The patients were assessed using Nurick and mJOA scores before surgery, then at 12 months, and finally 24 months after surgery. In addition, they were preoperatively examined with a battery of evoked potentials (EP) - somatosensory evoked potential (SEP) and motor evoked potential (MEP) tests. Based on EP, principal spinal cord disability was determined: A - anterior (maximum changes in MEP), P - posterior - maximum change in SEP). The entire group was, on the basis of EP partitioning and the surgical approach used, divided...

Modelling of changes of the intracranial pressure (ICP) during physiological and pathological processes
Vaněk, Petr ; Otáhal, Jakub (advisor) ; Suchomel, Petr (referee) ; Sameš, Martin (referee)
The more we know about the circulation of CSF through ventricle system, brain parenchyma, subarachnoideal space and the development of intracranial pressure (ICP), the more we understand different pathologies and pathological processes of the central cervous system. The knowledge about the basic hydrodynamic charecteristics of craniospinal system is a key factor for understanding a wide range of pathological situations affecting CNS, these are for example intracranial hypertension, normal pressure hydrocephalus and syringomyelia. In the presented paper, we are presenting a newly developed measuring system Visionbrain that enables us to gain the biological data and consequently to analyse them. At the same time, the results of such measurements were used to specify the compertmental model of CSF circulation. The model devides craniospinal system into five divisions - two intracranial and three spinal. Such model is the third generation of this model and, compared to the older version, it includes two intracranial veins. Thanks to this stucture, the model enables us simultaneous modeling of heart and respiratory pulsations of CSF. Compared to the other published models, it also includes defined structure of spinal part. The model is derived using laws of conservation and it encompasses pressure...

Neuromodulation-the importance ofpostoperativeepiduralfibrosis
Masopust, Václav ; Pokorný, Jaroslav (advisor) ; Suchomel, Petr (referee) ; Hakl, Marek (referee)
Background Epidural fibrosis (EF) is defined as nonphysiological scar formation, usually at the site of neurosurgical access into the spinal canal, in intimate vicinity to and around the origin of the radicular sheath. From the very onset, EF behaves as a reparative inflammation causing, as a rule, symptoms of characteristic nature and clinical course (pain). Treatment of epidural fibrosis causing failed back surgery syndrome (FBSS) by neuromadulation technique is very expensive. Finding of suitable parameters for the indication of treatment is therefore very important. Aims The study is based on evidence of the importance of epidural fibrosis for the development of chronic pain. Research is also focused on the comparison of the range fibrosis and the effect of stimulation (spinal cord stimulation - SCS). The goal is to find a suitable selection factor for the indication of neuromodulation. Methods I. A double-blind prospective study was conducted to investigate a cohort of 200 patients requiring surgical treatment for intervertebral disc hernia (hernia disci intervertebralis). The patients were randomly and blindly divided into 2 groups, one on peroperatively applied local doses of a mixture containing corticosteroids, the other without such medication. All the requirements of a double-blind...
