Syndrom vyhoření / Burnout syndrome

Kratochvílová, Anna January 2016 (has links)
This dissertation deals with the topic Burnout Syndrome. Burnout syndrome stands for a state of exhaustion, emotional withdrawal and loss of confidence in personal performance. The dissertation consists of two parts, namely the theoretical part and the research part. The literature research part summarizes theoretical findings on the subject, such as a characteristic of burnout syndrome, its causes, symptoms and development or diagnostic methods. The analysis of these topics is based on individual authors research. In the research part findings gained from the theoretical part were used and verified. The chosen organization, a state institution, the Industrial Property Office of the Czech Republic, is briefly characterized. This part evaluates the incidence of burnout syndrome among employees in the selected organization. Information for the research part was obtained using a questionnaire aimed at both, managers and staff without additional subordinates. An unstructured interview with the President of the Office was also conducted. The information acquired was evaluated and interpreted and subsequently measures were proposed to eliminate identified inadequacy.

VESNICKÁ SÍDLA JAKO BIOCENTRA. VYUŽITÍ MAPOVÁNÍ ROSTLIN PRO HODNOCENÍ BIODIVERZITY. / Village{\crq}s places as biocentre. Improvement mapping plants to evaluation biodiversity.

RÁDR, Jiří January 2008 (has links)
The main aim of graduation theses was today{\crq}s loom of species distribution, which were in former times surely ample in integral area Blatensko. On the basis of it to rewiev the diversity. With village{\crq}s alternation the diversity changed, too. The 22 villages scattered in the whole area phytogeografically subregion Blatensko and the 59 plant species from archeofyts, apofyts and neofyts were selected. My objective was to note, if these species are still occurred in Blatensko region or not. The number of monitored plant species decreases and every year are more and more abundant.

Neologismy v současné angličtině

RŮŽIČKOVÁ, Andrea January 2010 (has links)
This thesis is to determine the word neologism as a term based on the present-day vocabulary point of view and furthermore, it tries to identify the formation processes based on which new words come to being. It also tries to analyze which of the formation processes dominate and which of them are no longer used. This analysis further observes the spheres, where neologisms most frequently occur. In spite of the fact that it may seem that new words can appear everywhere, there are areas, where they are more frequent than elsewhere. Such areas may be the IT sphere, scientific field and, of course, the pop culture.

Výskyt parazitů zažívacího aparátu u telat ve stáji a ve venkovním odchovu. / Prevalence of gastrointestinal parasites in calves reared indors and in hutches.

MOTTLOVÁ, Markéta January 2008 (has links)
On two farms in a two-year period (spring 2005,autumn 2005, spring 2006, autumn 2006) calves faecal samples from the rectum or from the floor were obtained for parasitologic examination. A total of 560 samples from 209 calves were examined using the floatation method in Sheather's sugar solution. In positive samples the presence of Giardia intestinalis cysts, Cryptosporidium parvum, C. andersoni and Eimeria spp. oocysts was found. The infection by C. parvum was the highest from the 1st to the 3rd week and the infection by C. andersoni was the highest from the 7th to the 8th week of the calves age. In both breedings Coccidia Eimeria spp. was the most diagnosed, followed by G. intestinalis. With calves bred in stables by two a higher probability of parasitic infection was detected (46,9 %) compared to breeding of calves in outer individual boxes (17,6). The excrements of the calves were mainly of pasty or even of mushy consistence and the prevalence of the parasites was in most cases diagnosed in single infections.

Hnízdní preference jiřičky obecné (Delichon urbica) v urbánní krajině

Dvořáková, Denisa January 2019 (has links)
The thesis evaluates the birdlife preferences of the common house martin in the territory of the Czech Republic. The survey of the literature focuses on obtaining information from available sources that relate to nesting preferences according to different criteria, such as environmental habitat conditions, influence of the human factor, and others. In the practical part of the thesis 12094 records have been collected concerning the nesting of the common house martin in the Czech Republic in the period from 2009 to 2017, drawn from the faunistic database of the Czech Society for Ornithology. The data was correlated with the data on the conditions found in the separate habitats and analysed by the statistical methods Boosted regression trees (BRT) and Generalized Least Squares (GLS). The obtained results show that owing to the insect life the common house martin most prefers the areas with field and wetland ecosystems, and rather also the suburban lowland region. A major negative influence on the common house martin appeared to be mining areas in industrial estate.

Dynamika výskytu orchidejí ve vybraném modelovém území v horských polohách / Dynamics of orchid occurrence in highlands

Černocká, Veronika January 2018 (has links)
All species of orchids are sensitive plants and records of their distribution are rare. Their rarity is related to their complex biology and their sensitivity to changes in the environment. It is necessary to pay attention to these threatened species, so that we could preserve them from extinction. For their effective protection we need to know the main causes of extinction of their localities. It is also useful to know the factors, which determine their distribution, so that we could find new localities, where they occur. In this thesis I analyzed some climatic, geographic and ecological factors in the Jeseníky mountains and their surroundings. First, I visited localities of orchids, which were registered in large databases of their presence in the past. The four most numerous species were analyzed using the program MaxEnt. Based on the revisions, existence of 2/3 of the revised localities was confirmed, 8% of the revised localities became extinct because of overgrowth or due to human intervention in the landscape. From the MaxEnt results it is clear, that for all species the most important factor at the 50 × 50 m scale, is the type of biotope and heterogeneity of the countryside. The most suitable biotopes are floodplain and wetland forests, mesophile meadows, natural scrubs, peat bogs and...

Výskyt parazitů zažívacího aparátu u mladého skotu. / Prevalence of parasites of alimentary system in young cattle.

ŽIDKOVÁ, Marcela January 2007 (has links)
In biennial following (spring 2005, autumn 2005, spring 2006, autumn 2006) we're rasitology examine 288 samples dropping from heifers and 288 samples dropping from bulls. Exhibits we're examined floatation in Sheather´s sugar solution. In examinate dropping we're proved present cysts Giardia intestinalis and oocysts Cryptosporidium andersoni and family Eimeria. In heifers was most frequent parasites coccidia Eimeria sp. (28,5 %). Flagellata Giardia intestinalis occur in 17 % of all designs. At least we're open up Cryptospordium andersoni (9,4 %). In bulls we're noted highest occurrence coccidia Eimeria sp. (19,1 %). Almost same occurrence we're found out near Giardia intestinalis (18,8 %). Very low prevalence we're have observed near Cryptosporidium andersoni (1,4 %).

Ellagotaniny - výskyt, metabolismus a účinky na lidský organismus / Ellagitannins -occurence, metabolism and effects on human body

Raabová, Karin January 2017 (has links)
CHARLES UNIVERSITY PHARMACEUTICAL FACULTY IN HRADEC KRÁLOVÉ DEPARTMENT OF PHARMACEUTICAL BOTANY AND ECOLOGY Title of the Diploma thesis: ELLAGITANNINS - OCCURENCE, METABOLISM AND EFFECTS ON HUMAN BODY Candidate: Bc. Karin Raabová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Diploma thesis 2016/2017, pp. 77 Ellagitannins belongs to a class of hydrolysable tannins, which are susceptible to hydrolysis to give ellagic acid in the digestive tract. Ellagitannins occur in many plant families, for example plants in the family Rosaceae, Myrtaceae or Lythraceae. There are naturally found in some fruits (pomegranate, strawberries, blackberries, raspberries, grapes), but also in the seeds of walnuts and thus form a diverse group of bioactive polyphenols with anti-inflammatory, antitumor, antioxidant and antimicrobial activity. Special instrumental methods (HPLC, DAD, MS) are most often used for subsequent evidence of occurrence of these compounds in plants and their identification. This diploma thesis is a literature review, which aimed at processing the available knowledge about the ellagitannins. Attention was focused on the biological activity demonstrated in an animal or human organism. Keywords: ellagitannins, occurrence, metabolism, effects, human body

Procesy řídící sympatrickou koexistenci di- a tetraploidního cytotypu v primární kontaktní zóně chrastavce rolního (Knautia arvensis agg.) / Processes governing sympatric coexistence of di- and tetraploid cytotypes in primary contact zone of Knautia arvensis agg.

Hanzl, Martin January 2012 (has links)
Intensive cytotype screening in the primary contact zone of relict serpentine Knautia arvensis agg. revealed a striking predominance of the derivative tetraploid (81 % of subpopulations) over the diploid maternal race. Eleven mixed-ploidy subpopulations with the close spatial proximity of both cytotypes were identified. Flow cytometric analyses of almost 5 000 individuals led to discovery of two extremely rare minority cytotypes (3x, 6x). Vegetation analyses were made at two different spatial scales and in both cases confirmed the absence of distinctions in habitat preferences of cytotypes. Slight microhabitat segregation of cytotypes was however apparent at the finest spatial scales. Cytotype distribution within mixed-ploidy sites was not random. Striking patterns of cytotype clumping into cytotype uniform patches and negative spatial correlations between diploid and tetraploid individuals were apparent at all sites. Distribution of life cycle stages of diploids and tetraploids within the mixed-ploidy subpopulations were significantly different. The clonality was the most common mode of reproduction in the subpopulations of both cytotypes. Seedlings accounted for only 7 % of new plants. Significant distinctions in the plant vigour between the cytotypes were showed during the in situ comparison in...
