Nursing care after coronary artery bypass grafting
Chalupová, Veronika ; Vaňková, Milena (advisor) ; Brůček, Petr (referee)
Coronary artery bypass grafting (RIA, RMS, RD and RIVP) was performed in 59 years old man. Duration of cardiopulmonary bypass/cross clamp was 55 min/40 min resp. There were no complications during the operation. The main topic of the work is to describe and evaluate nursing care process. There are several pillars of modern and effective nursing care starting with M. Gordon s rules and WHO statements on the other hand. The nursing care of our patient had several stages - preoperative, early postoperative, early rehabilitation and full rehabilitation with the end of hospitál stay. On the preoperative day the patient was fully educated about process of operation and postoperative care. Early postoperative care was slightly complicated with bleeding, anyway the problem was solved without surgical intervention. Further nursing care (pain control, pulmonary rehabilitation etc.) was without complications. Just before leaving home after succesfull operation the patient was educated in secondary prevention of ischemic heart disease.

Emissions of greenhouse gases (N2O and CO2) from pasture soil as a result of activity of soil microbial community - preliminary results
Šimek, Miloslav ; Hynšt, Jaroslav ; Brůček, Petr ; Čuhel, Jiří
Cattle overwintering area was shown an important point source of N2O and CO2. The emissions of N2O were mostly directly related to the rate of animal impact as the greatest fluxes of N2O and the highest total cumulative N2O emissions as well were found at the most impacted site. The fluxes of N2O were however very variable in time and most of N2O was emitted during several short events in spring or in winter. Laboratory experiments suggested that total amount of nitrogen escaping from soil from impacted sites is much greater than indicated by field measurements of N2O fluxes and molecular nitrogen (N2) was shown as the main nitrogen gas. It is hypothesized that soil pH is a crucial soil factor controlling the mole fraction of N2O: under slightly alkaline conditions in severely impacted soils, denitrification is completed and most of nitrogen escapes from the soil as N2; under more acidic conditions, however, the activity of nitrous oxide reductase is partly reduced.

Dynamics of N2O emissions after C and N amendments of soil at the cattle overwintering area
Hynšt, Jaroslav ; Brůček, Petr ; Čuhel, Jiří ; Šimek, Miloslav
Field experiments were carried out at the cattle overwintering area in South Bohemia, Czech Republic, focused on the emissions of N2O after soil amendments with nitrate and glucose. Emissions were estimated using a permanent static chamber technique. Nitrate and glucose amendments caused very sharp increases of N2O fluxes, which however diminished after 2-3 days. Total amount of N2O escaping the soil was related to the amount of N and C added, and was calculated to 1-15 kg N.ha-1 (0.2-3% of N applied). Emissions were heterogeneous, which is shown by great differences among the individual chambers. Emissions were variable in time and very probably were controlled by temperature, as they approximately followed the air and surface soil temperature patterns. Despite the timing of amendment application, peaks of emissions were always determined 6 hours after the amendments.
