Steponkienė, Ana 25 June 2014 (has links)
Ixodes genties erkės yra krauju mintantys nariuotakojai, visų – stuburinių gyvūnų, taip pat žmogaus parazitai. Ixodes ricinus erkės perneša daugybę ligų sukėlėjų, tokių kaip: erkinio encefalito (erkinio encefalito virusas), Laimo ligos (Borrelia burgdorferi sensu lato bakterijos), bebeziozės sukėlėjus (Babesia microti ir Babesia divergens). Taip pat platina ir Anaplasma phagocytophilum bakterijas. Šiuo metu erkių platinamos ligos yra dažniausios vektorių sukeliamos infekcijos Europoje. Pastaraisiais metais išpopuliarėjo molekulinės biologijos metodai, paremti patogenų nukleino rūgščių polimerazės grandinine reakcija ir RLB hibridizacija. Šie metodai laikomi tinkamiausiais, jautriausiais ir specifiškiausiais erkių platinamų ligų sukėlėjų diagnostikai. Šiame darbe naudoti molekuliniai metodai erkių platinamų ligų sukėlėjų: erkinio encefalito viruso, Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato ir Babesia spp., nustatymui iš 2200 erkių, surinktų keturiuose Lietuvos rajonuose. Tyrimų metu nustatyti šeši erkinio encefalito viruso infekcijų atvejai, iš kurių penki teigiami mėginiai nustatyti Radviliškio raj. surinktose erkėse ir vienas – Utenos raj. Anaplasma phagocytophilum bakterijų infekcijos yra dažniausiai pasitaikančios infekcijos Lietuvos erkėse. Tyrimų metu nustatyti 37 (3 %) teigiami Anaplasma phagocytophilum mėginiai, iš kurių 17 (46 %) nustatyti Kėdainių raj. surinktose erkėse, 15 (32 %) – Klaipėdos, 5 (14 %) – Radviliškio ir 3 (8 %) – Utenos raj. Tarp šių... [toliau žr. visą tekstą] / Ticks of genus Ixodes that infect livestock, deer, dogs, and a wide variety of other species including humans. Ixodes ricinus can also transmit numerous diseases including tick-borne encephalitis, Lyme diseases (Borrelia burgdorferi sensu lato infections), babesiosis (Babesia microti and Babesia divergens infections). It can also spread Anaplasma phagocytophilum bacteria. Now tick-borne infections are the most frequent human vector-borne infections in Europe, the incidence of these infections has been on rise, and new infections have emerged. In recent years, molecular detection methods based on PCR amplification of the nucleic acids of pathogens and Reverse Line blot hybridization have been showed to be effective, sensitive and specific methods for diagnosis of tick-borne diseases. In this work were used molecular detection methods for tick-borne pathogens: tick-borne encephalitis virus (TBEV), Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, and Babesia spp., diagnostics in 2200 ticks collected in four Lithuanian regions forests. During investigation were identified six cases of TBEV, which five positive samples were from ticks collected in Radviliškis region and one from Utenos region forest. Anaplasma phagocytophilum bacteria infections were most frequent in Lithuanian ticks, during researches were identified 37 (3 %) cases (17 (46 %) in Kėdainių region, 15 (32 %) – Klaipėdos, 5 (14 %) – Radviliškio, and 3 (8 %) – Utenos region). In these 81 % were in adult... [to full text]

To evaluate the quality of the bearing without disassembling it, vibration signal monitoring and analysis methods were used. The following tasks were completed in order to accomplish the goal of the thesis: • Reviewed bearing quality evaluation and failure detection methods used in industry. • Created and implemented a method which could evaluate the quality of a bearing. • Experimentally tested the efficiency of the method. • Investigated the used oil influence on the quality detection. The quality of the bearing and its elements can be measured using bearing elements vibration acceleration root mean square method. This method does not require the disassembling of the bearing which might not be avoided when using other methods. The efficiency of the method was proven by performing extensive mechanical analysis on studied bearings, which required to disassemble the bearing and check in detail the quality of the bearing. The collected results were compared with the ones received from the implemented method. Some additional methods were created and implemented which would give more information about the bearing and its quality. The vibration acceleration signal centering method was implemented and its efficiency was checked experimentally.

Úprava, ověření, standardizace a vydání elektronické podoby screeningového dotazníku Dětské autistické chování (DACH) / Editing, validation, standardization and preparation for publication of electronic version of an screening diagnostic questionnaire DACH

Šporclová, Veronika January 2016 (has links)
The questionnaire DACH was created within the pilot survey of the dissertation project of PhDr. Kateřina Thorová, Ph.D. Since it was put into practice, the questionnaire has become a relatively common tool used in the diagnosis of Autism Spectrum Disorders. The theoretical section of my dissertation introduces the reader to the wider context of Autism Spectrum Disorders - from ethiology to treatment (therapy). The empirical section then focuses on editing, validation and standardization of the DACH questionnaire created by Thorová. Empirical testing of the DACH was conducted on a sample of 240 people. Statistical analysis of the collected data demonstrated a relatively high level of reliability, sensitivity and specificity of the method, along with a high predictive value of positive results. The correlation between the questionnaire results and the results of the diagnostic assessment with the use of the methods of the "golden standard" for autism was lower, but can be considered as satisfactory. The main goal of my dissertation is to develop a standardized Czech method for screening early symptoms of autism in children. For wider access of the practical applications of this project, an electronic version of the DACH questionnaire is available, including scoring and general recommendations. The...
