Fathers'motivations for the presence at childbirth and their experiences in the sociological perspective
Krajíčková, Michaela ; Dudová, Radka (advisor) ; Lupač, Petr (referee)
This theses focuses on finding out the reasons for fathers to be present at childbirth and how they experience childbirth. These goals are viewed from a sociological point of view and therefore the topic is connected with sociological theories and also society's view of the father at birth. The theoretical part also mentions the development of society in terms of fathers at childbirth and related changes in society in connection with intensive fatherhood. The empirical part uses an interpretive phenomenological analysis in the form of a qualitative interview, which is important for a better understanding of respondents. It was found out what are the motives of fathers to go to birth, how they perceive the presence of fathers and how they experience the birth itself. The thesis discusses the influence of personality characteristics on the motives and experiences of fathers based on the information obtained. This research is exploratory and is perceived as a preliminary research for, in the future, quantitative research, which will develop the obtained information and results and thus it will be possible to find out possible connections between the motives for presence at birth and personality characteristics. Based on the information obtained from the interviews, we could say that the most common...

Determination of Pb sources in small catchment using Pb isotopes.
Krajíčková, Michaela ; Mihaljevič, Martin (advisor) ; Strnad, Ladislav (referee)
The contents and isotopic composition of lead (Pb) were studied in a small forested catchment Lesní potok. The catchment is located 30 km southeast from Prague near Jevany. Monitoring inputs and outputs in GEOMON, a network of small forested catchments in the territory of the Czech Republic, has been coordinated by the Czech Geological Survey since 1994. It was analyzed litter of spruce and beech, collected between 2013 and 2014, and an archival sample litter of spruce from 1997. Lead in soil was studied at two profiles cambisols in each diagnostic horizons. Samples of profile LP 38 were collected in 2005, the LP 39 a year later. Surface water and bulk precipitation were sampled monthly for one hydrological year 2013. The ICP-MS method was used to determine the concentration and isotope ratios of lead. To determine of sources Pb were used isotope ratios 206 Pb/207 Pb and 208 Pb/206 Pb. In spruce litter (3,87 mg.kg-1 ) was measured average Pb concentration higher than beech (0,98 mg.kg-1 ). Topsoil horizons contain elevated concentrations of Pb (up to 100,70 mg.kg-1 ) decreasing towards the deeper horizons. The Pb concentration in the soil was 61,28 mg.kg-1 . Bulk precipitation in with average Pb concentrations206 Pb/207 Pb = 0.87 µg.l-1 contained more Pb than surface water 206 Pb/207 Pb = 0.50 µg.l-1 ....

Lead and its Effects on Health under the REACH
Krajíčková, Michaela ; Bendl, Jiří (advisor) ; Mihaljevič, Martin (referee)
With decreasing use of leaded petrol and the subsequent creation of further restrictions of lead exposure in an urban environment plummeted. Because lead is still available in several types of articles, the reduction of lead in our environment has come to a halt before reaching sufficiently low levels. New EU regulation REACH introduces new rules for the marketing of substances, mixtures and articles on the market. In September 2012, ordered by the European Commission under the REACH proposal banning the use of lead and its compounds in jewelery. It is now proposed to limit lead in products, such as shoes, clothes, accessories, interior decoration, pens and keys. The objective of the thesis is to inform about the presence of lead in consumer commodities and its dangers. Lead and its compounds are highly toxic and can cause lots of health issues. Especially its neurotoxical effects can affect the development of children nervous system, so it is essential to lower the occurence of lead in products on the market.
