Police activity as an IZS unit in finding ammunition with specialization in aerial bombs in inhabited areas.
ZIKMUND, Pavel
It's been almost 70 years since the end of the worst military conflict of all times, the World War II, during which millions of people died. It is a sad fact that it still causes casualties even today. The problem lies in thousands of different pieces of munitions located throughout Europe. The biggest problem is posed by unexploded aerial bombs that have in recent years took its toll on bomb disposal experts as well as other people. The problem of aerial bombs are mainly American and British origin, which bear long-term mechanical - chemical igniter. The design of these igniters does not allow their simple unscrewing from the body itself, and even the handling of these aerial bombs may cause its explosion and the threat to all persons located in its vicinity. Even in our country can be found these air bombs with this type of igniter. This thesis deals with the possibilities of such a disposal with regard to economic and technological possibilities of the Czech Police bomb disposal experts. Therefore, research was conducted with a focus on how best to dispose of aerial bombs. Bomb disposal experts were approached to give their professional opinions. A part of the research was the study of foreign literature dealing with this issue. The sad fact is that this problem is not satisfactorily resolved anywhere in Europe. Abroad, various methods were used as appropriate, such as using high pressure water cutting or blasting the use of special keys. As demonstrated by accident in 2010 when in German Göttingen three bomb disposal experts died in liquidation of aerial bombs using high-pressure cutting, this method and similar have proven to be inappropriate. The preparation of these special methods takes an excessively long time, and in many cases the bomb requires manipulation. Bomb disposal experts of the Czech Republic along with other experts are developing and improving the explosive separation method using a special explosive (ammunition). The most appropriate seems the use of long flexible bomb explosive: RAZOR made by a Czech company - VÚPCH Pardubice - Semtín. The explosive is attached to the body of the bomb either on its perimeter or in the axis of the bomb and this leads to the separation of the lighter or pull out the body of the lighter without explosion of the body of the bomb. Practical experience shows that the use of this special method can reduce time to prepare bomb disposal and the handling of the bomb is minimal or none. Unfortunately, there is always a risk that there will be accidental explosion of aerial bombs and therefore is imperative to comply with all safety measures to the maximum extent possible.

Blastocystis in pigs
LAKATOSOVÁ, Lucie
The genus Blastocystis belongs among anaerobic unicellular, polymorphic organisms living in intestinal tract of many invertebrates and vertebrates including humans. Genetic variability and spectrum of hosts of this protist is tremendous. Several subtypes exist that are able to inhabit intestine of specific hosts. For example, the subtype 3 is probably the only human-borne subtype and is therefore most often isolated human subtype. It not clear how many species of Blastocystis exist. Anyway, the best known one is B. hominis isolated from humans. It is possible that Blastocystis is responsible for some diseases. It can be found in both healthy individuals and patients with gastrointestinal disorders. The Blastocystis infection can spread easily via orally transmitted cysts. Blastocystis is commonly found in epidemiological studies. During the year 2009/2010 I collected samples in the breeding and production facilities of a pig farm from different categories (bred or auction sows and boars, female barren, gravid, suckling, and one bred boar). A total of 46 samples was cultivated using two-phase media (Dobell Leidlaw).In most specimens I found Blastocystis and, to a lesser extent, trichomonads.

Confirmation of presence of chemical grouts in grouted rocks - proving methods
Ščučka, Jiří ; Vaculíková, Lenka
The confirmation of a presence of chemical grouts in the pore system of fine-grained soils or in the fine cracks of grouted rocks and engineering constructions is a common requirement in the laboratory analyses of geocomposite material (polyurethane resin+rock/soil, polyurethane resin+building material). The combination of two analytical methods can be used for the reliable detection of the injection medium in the grouted rock environment: optical fluorescence microscopy+digital image processing, - Fourier transform infrared (FTIR) spectroscopy of the powdered rock/soil sample.

Hora, Petr ; Šiňor, M.
In this contribution we pay attention to the propagation of the stress waves in an arbitrary complex inhomogeneous media. For the system of elastodynamic wave equations we have adopted the method of solution based on the local interaction simulation approach (LISA) and the sharp interface model (SIM).The implementation of LISA/SIM in 2D and 3D to computer codes is done in the C programming language. Preprocessor is done in the programming language Python with graphics library wxPython/wxWindows.

Nanometrology coordinate measurement machines uncertainties caused by frequency fluctuations of the laser
Hrabina, Jan ; Lazar, Josef ; Číp, Ondřej
One of considerable sources of displacement measurement uncertainty in nanometrology systems such as multidimensional interferometric positioning for local probe microscopy is the influence of amplitude and especially frequency noise of a laser source which powers the interferometers. We investigated the noise properties of several laser sources suitable for interferometry for micro- and nano-CMMs (coordinate measurement machines) and compared the results with the aim to find the best option. The influences of amplitude and frequency fluctuations were compared together with the noise and uncertainty contributions of other components of the whole measuring system. Frequency noise of investigated laser sources was measured by two approaches – at first with the help of frequency discriminator (Fabry-Perot resonator) converting the frequency (phase) noise into amplitude one and then directly through the measurement of displacement noise at the output of the interferometer fringe detection and position evaluation. Both frequency noise measurements and amplitude noise measurements were done simultaneously through fast and high dynamic range synchronous sampling to have the possibility to separate the frequency noise and to compare the recorded results.

Analysis of the meat oxherd breeds in an organic agriculture
ŠEBELKA, Štěpán
The aim of this thesis was to analyze the results of the Aberdeen Angus meet herd breeding in an ecological farming with the welfare relationship to the animals and at the same time to compare the efficiency after the system change of the farming at the farm Angus, Rančice, owned by Milan Šebelka. The research was done in the period of years 2005 ? 2012. The survey range includes 80 heads of thorough-bred cows as well as 266 heads of Aberdeen Angus calves born in the tracked period. The number of births and calving interval was dated by the cows. By the calves we noted the live weight and average daily gain in the growth process. The population of the calves was then sorted our by year of the birth, sex and by the way of farming. The data entries were elaborated in the MICROSOFT EXCEL and evaluated in STATISTICA. The cows had the calving interval of the period often from 351 to 380 days. In the herd with the most cows occurred at 3rd calf length interval. By the monitored number of calves no matter of the sex was noted the lowest live weight by the birth in transitional period (37.97 kg). The group of calves born in organic farming reached the highest average weight by the birth, in 120 days as well as in 210 days (38.88 kg, 190.91 kg, 307.81 kg). The lowest average weight in 120 days was noticed in transition period (176.93 kg), in 210 day in transition period again (271,56 kg). The best growth ability from the birth to 120 days was by the group of calves born in organic farming (heifers ? 1.177 kg, bulls ? 1.353 kg) compared to the lowest result in transitional period (heifers ? 1.091 kg, bulls ? 1.215 kg). The average daily gain from 120 till 210 days reached its minimum transitional period (heifers ? 1.082 kg, bulls ? 1.233 kg), the maximum numbers were noted in organic farming (heifers ? 1.253 kg, bulls ? 1.343 kg). The growth intensity from the birth till 210 days its minimum transitional period (heifers ? 1.074 kg, bulls ? 1.154 kg), the maximum numbers were noted in organic farming (heifers ? 1.209 kg, bulls ? 1.347 kg). In the ecological agriculture system was noted statistical better efficiency results (live weight, growth intensity) compared to conventional agriculture system.

KALBÁČOVÁ, Lucie
This master thesis is concerned with the analysis of methods of fixed assets acquisition, with a focus on leasing. Its aim is to evaluate the acquisition of fixed assets through leasing in comparison with alternative forms in the limited liability company Servistrade s.r.o. in terms of the financial resource provider. The theoretical part describes fixed assets, their classification, leasing, alternative forms of property acquisition and comparison thereof. The practical part begins with the characteristics of Servistrade s. r. o. The analysis is made upon the actual data submitted by the company. For the fixed assets acquisition, the company may provide leasing, instalment sale or bank loan. Evaluation of the best variant of assets acquisition (from the Servistrade provider?s viewpoint) was done in terms of cash flow, income tax and VAT. The evaluation was also conducted from the perspective of the tenant MMC Pardubice s. r. o.

Management of Nursing Care for Newborn Using Classification Systems NANDA, NIC and NOC
MICHALOVÁ, Veronika
We have dealt in this thesis with problems of nursing care of the newborn from the perspective of standardized classification systems NANDA, NIC and NOC which offer many opportunities for streamlining, simplifying and improving of the quality of care. The theoretical part of this thesis focuses on nursing care of physiological newborn during the first moments after the birth until leaving hospital. Furthermore, the common nursing language which is included in standardized classification systems NANDA, NIC and NOC.The empirical part of the thesis was prepared with the help of qualitative - quantitative strategy. We chose to collect valid data a research method of content analysis of documents, modelling, thought experiment and a structured interview. The first aim of the research was to identify the use file from various classification systems related to nursing care of physiological newborn. We selected 9 nursing diagnoses from the publication NANDA International Taxonomy II through content analysis, 9 nursing interventions from Nursing Interventions Classification (NIC), 5 expected results related to the care of physiological newborn from the publication Nursing Outcomes Classification (NOC). We worked out a research form and submitted it in the way of a specific questionnaire to the validation of respondents ? who were experts in the field of nursing care of the newborn, it was made from the selected NANDA nursing diagnoses, NIC interventions and expected results of NOC. The second aim was to verify the usability of the selected files from the classification systems NANDA, NIC and NOC in clinical practice. The results of validation of NANDA nursing diagnoses were done by Diagnostic Content Validity Model ? DCV by Fehring. We determined the absolute and relative frequency of their designation within classification systems NIC and NOC. Nurses working at neonatal wards were our basic research populations; we created a targeted selection of two research samples divided by educational attainment. The first research sample consisted of 20 nurses with university education. The second research group was represented by 18 nurses with secondary education. The survey was realised in the time from January to March 2013 in the neonatal wards of the Hospital České Budějovice, a.s. Hospital Strakonice, a.s., Hospital Písek, a.s. Our third aim was to determine the attitudes of neonatal nurses to usage of classification systems in daily practice. We focused questions directed to the respondents on the knowledge and source of acquired knowledge, their attitude and possible reasons preventing the implementation of classification systems into clinical practice. The results showed nurses are reluctant to the usage and implementation of new standardized classification systems into clinical practice. The output of this thesis is the basic concept of nursing diagnosis according to NANDA-I, NIC and NOC focused on nursing care of physiological new-born in the area of the Czech Republic. 12 NANDA nursing diagnoses taxonomies was verified with 128 characteristics, 9 NIC nursing intervention taxonomies with 183 activities and 5 results of NOC nursing care with 72 areas of evaluation. There was selected in this survey 100 characteristics of NANDA taxonomy (62 %). It was chosen as being applicable in practice 130 from 9 selected files of NIC (71 %). It was selected 39 indicators (54 %) within 5 files of expected NOC results. The survey brought a lot of interesting information and also revealed even the lacks in the area of nursing care of physiological new-born; research also showed the lack in the area of nursing care of physiological newborn.

The genome size determination in sturgeons using 2-D a 3-D image cytometry.
SRP, Jiří
The genome size of evolutionary polyploid, neopolyploid and hybrid sturgeons is well known for its high variability. Aim of this study was 1) to specify the genome size of polyploid and neopolyploid sturgeons using an analysis of 2-D and 3-D images of specifically stained cells nuclei, 2) to evaluate the samples of populations for cytogenetic analysis needs and thereafter, 3) to compare both methods and record the data either for next research or for negative selection from the broodstock. This test has been done at the laboratory of molecular, cellular and quantitative genetics, Faculty of Fisheries and Protection of Waters USB in Vodňany using all sturgeons spawners and using samples obtained from some foreign fish farms which cooperated with the faculty. The samples included A. ruthenus, A. baerii, A. stellatus, A. gueldenstaedtii and Huso huso, intentionally bred hybrids of A. gueldenstaedtii (8n) x A. baerii (12n), A. baerii (8n) x A. ruthenus (4n), A. gueldenstaedtii (8n) x A. baerii (10n) a A. gueldenstaedtii (8n) x A. ruthenus (4n). As methods have been chosen image cytometry and confocal microscopy which use image digitalization and subsequently its computer analysis. The genome size was measured from the size of specifically stained nuclei of erythrocytes in specimens sampled. Result of this study was measuring the genome size in sturgeons under study using different methods, recording the obtained data, description of spatial conformation changes of cell nucleus with increasing ploidy level and deduction of impact to their physiology and comparing the methods between each other. The conclusion is necessity of another sturgeons genome size determination , choice of the best methods for more effective search and research of non-standard individuals and subsequently an examination of their physiological differences.
