Production of CO2 and emission trading system
Bravený, Adam ; Niesner, Jakub (referee) ; Ferdan, Tomáš (advisor)
The thesis is divided thematically into two parts. The first one describes the state of gaseous carbon dioxide production, being considered the main cause of greenhouse effect or global warming. By the summary of many sources it is revealed how CO2 is produced, what influences its concentration in air the most and the CO2 level trends. The second part is focused on European Union and Czech emissions trading system, which is actual and widely discussed topic in the last few years. The main rules, mechanisms of the market and a model case of allowances trading is presented. The existence of the whole system and its positive and negative effects on the economy and environment are discussed.

Vascular disorders of gastrointestinal tract - Diagnostics and endovascular therapy
MOKRÁ, Michaela
An important group of diseases affecting gastrointestinal tract is derived from impaired function of the blood vessels. These disorders involve bleeding (arterial and venous), aneurysms and intestinal ischaemia. Interventional approaches to treat gastrointestinal haemorrhage differ in arterial and venous bleedings. In treatment of arterial bleeding, embolization techniques are utilized for selective occlusion of a damaged artery. In case of venous varices, transjugular intrahepatic portosystem shunt (TIPS) must be introduced. Chronic mesenteric ischaemia is relieved by angioplasty with a stent placement. Endovascular extraction in acute intestinal ischaemia is performed with aspiration thrombectomy of the blood clot at the site of peripheral vascular occlusion. In our department, we treated 99 patients with disorders of gastrointestinal blood vessels in the course of two years. In 27 patients, we searched for the cause of arterial bleeding (in 33.3%, the bleeding was not confirmed). We performed 24 embolizations. In 55 patients, TIPS was placed; of these, additional embolization of portosystemic collateral was performed in 44 patients. Two patients suffering with mesenteric ischaemia were treated with PTA and stent placement. Seven patients with intestinal ischaemia were treated with the use of aspiration thrombectomy with a promising result - a complete recanalization was reached in 4 cases. Nowadays, endovascular therapy is a method of choice in therapy of vascular disorders of the gastrointestinal tract. In correct indications, endovascular therapy represents a save and effective method that shows a relatively good technical and clinical efficacy.
