Water jet cutting of material
Jáchym, Jan ; Fialová, Simona (referee) ; Habán, Vladimír (advisor)
This bachelor thesis describes principles developement and usage of high - speed water jets for cutting. In the first part, it features description water jet cutting technology and its application, basic parts of high pressure system and sorts of generators pressure. In the second part, it divides water jet according to discreteness in time and chemical constitution. In the third part, it deal with studies usage so - called pulse jets, especially at ultrasonically modulated ones. It is described mechanism rise and break up of modulated high - speed jet on individual pulses.

Study of plunger pump with linear motor
Jáchym, Jan ; Uttendorfský, Petr (referee) ; Pochylý, František (advisor)
This thesis deals with study and design of plunger pump with linear motor. This pump can be used for blood pumping in heart surgery. The theoretical part of this thesis is focused on description of extracorporeal circuit, heart boosters and artificial heart. This thesis provides an overview of check valves which are used in heart surgery too. Basic equitations for pump design are derived and calculated in this thesis. The pump design and manufacturing by the 3D technology was made by previous results. Finally, in this thesis are compared theoretical results and experimental data.

Education through the Geography in Curricular Reformation Period of Czech Education System: Reflection of the Changes at Selected Prague's Grammar Schools
Jáchym, Jan ; Chromý, Pavel (advisor) ; Hanus, Martin (referee)
The thesis, as the title suggests, focuses on education of Geography and analysis of Geography as a subject at Prague grammar schools. The aim of the thesis is to evaluate the impact of curricular changes on teaching Geography. Furthermore, the thesis is to analyze the ideas of the Geography teachers on teaching methods and content taught to students in their lessons. The work also evaluates the variety of opinions of the pedagogues concerning this topic. It also discusses their different views on a new form of the state leaving exam. Moreover, it looks for the answer whether the new exam might change the methodology of Geography. This work is mainly based on a critical evaluation of expert materials as far as the school reform is concerned. The empirical part itself consists of the survey results and the assessment of directed interviews with 11 respondents, who are the Geography teachers at nine Prague grammar schools.

Education through the Geography in Curricular Reformation Period of Czech Education System: Reflection of the Changes at Prague's Grammar Schools
Jáchym, Jan ; Chromý, Pavel (advisor) ; Hanus, Martin (referee)
The thesis, as the title suggests, is devoted to education in Geography. More specifically, the work analyzes teaching Geography at Prague grammar schools. The work objective is to assess the effects of the ongoing curriculum amendments on teaching Geography and to assess, analyze and review: a) The differences in the approach towards education in Geography at individual Prague high schools. b) The ideas of Geography teachers themselves on how much time should be devoted to particular geographical topics or topics otherwise related to Geography. Next, the work assesses the homogeneity of opinions in this respect. It also studies the homogeneity of particular Geography theme plans at individual schools also with respect to the planned change in school leaving exams. The work is based on a critical assessment of expert materials concerning the school reform. The empirical part itself is grounded in survey results and the assessment of directed interviews with 11 respondents, who are Geography teachers at 9 Prague grammar schools.
