The aim of this diploma thesis is to choose important reproductive parameters of sows from the available data, according to which it would be possible to statistically evaluate achieved reproductive level of analysed breed. It is necessary to define these parameters as accurately as possible with the shortest time required for measuring and collecting data. In the reproductive company SPV Plevnice were chosen 110 sows from different litters for the purpose of experiment. The day of weaning was on the 5th August 2015 and the sows were separated into 8 groups according to the order of actual litter, sow genotype and boar genotype, used for sow insemination. 13 basic reproductive parameters and 10 reproductive parameters reflecting sow genotype (BLBA x BAL) and boar genotype (4 breeds) BLBA = Czech large white x Landrace x Topigs, BAL = Czech large white x Landrase x Topigs x DanBred. The average value of born company piglets was 13,94. More specifically, total number of livebirths was 13,25 and total number of stillbirths was 0,68, which represents 4,88% of whole litter. Average number of weaned piglets per one sow and one litter was 12,16 with the loss of 1,06 piglet and statistical signifikance of risk and producing (p = 0,0436). The pregnancy rate after the first insemination reaches 89,82% and is influenced by average number of unproductive days 10,84 days. All these factors (including average lactation period of 27,06 days) forms meantime (154,03) with turnover 2,37 litters per year. As the most important factor is considered the indicator of weaned piglets per year, which in this case reaches 28,82 piglets/sow per year. In the next chapter there were given parameters in the term of old sow BLBA genotype and BAL genotype compared. In the next chapter the same comparation was used for boars. The impact of the breed was the best at sows of the last reproductive season, when the best boar L1536 had the highest number of livebirths with the average breeding loss (-1,1) 12,28 weaned piglets. Practically the same results had L1538 boar. However, in this case the number of livebirths was very low, so that the number of nurse sows was higher. The youngest L25 boar has the highest number of livebirths/sow per year, however concurrently the highest losses to weaning and therefore least weaned piglets in comparison with other boars. In terms of the distribution of the season, the worst results for the summer season (12.7 piglets born alive / litter).

Title Training and performance of a shot put thrower Aim of study The aim of study was to analyze performance development of shot put thrower Pavlína Radová in a five-year period. Analysis was focused on connection between the dynamics of athletic performance and the effect of training load during each of the two training cycles 2010/2011 and 2011/2012. Methods In this thesis, we used auto-analysis and comparison. Data for analysis of training load and performance development were obtained from the training diaries of the years 2010/2011 and 2011/2012. Results Sports performance development was majorly affected by character of training load and mental condition of the athlete in each yearly training cycle. Poorly chosen training load and insufficient regeneration lead to stagnation or decline in physical performance. Individual approach of the coach and his communication with trainee is very important. Key words Sports training, shot put, performance, analysis, training load

The aim of this thesis was to evaluate the reproductive performance of sows corporate program Czech PIC in a commercial breeding Ratiboř, Agricultural Cooperative Chyšky district Písek. The observed breeding herd was formed on December 31, 2016 with 119 sows and gilts. To evaluate the reproductive performance, the breeding-cows were divided into breeding sows inseminated and not inseminated, sow for 1st to 2nd litters (risk litters), 3rd to 5th litters (litter production) and for the 6th and higher. The breeding sows are frequently inseminated between 230th 269th day of life. In 2016, on average 25.2 live-born units were born per sow. The number of weaned piglets was at level of 21.8, it means the values were below the desired optimum. Good results were found in the length of intervening time (155.3 days), and the associated number of litters per sow. Sows reach 2.4 litters per year, and there is no problem with the beginning of rut after weaning. A rut mostly occurs on 4th and 5th day after weaning. The total cost for sows amounted to CZK 676,519.43 per year, when 1 kg of weaned pig costs CZK 53.75.

Entretanto, esses materiais são quimicamente instáveis, o que impede a deposição de alguns materiais solúveis sobre eles, como por exemplo, eletrodos de tinta prata. Para solucionar este problema, desenvolvemos uma matriz condutora e quimicamente estável formada pelo polímero condutor poli(3,4-etileno dioxitiofeno):poliestireno sulfonado (PEDOT:PSS) e pelo material sílica-orgânico 3-glicidoxipropil trimetilsilano (GPTMS). Foram produzidos compósitos de PEDOT:PSS/GPTMS com diversas concentrações de PEDOT:PSS, com os quais foram produzidos filmes uniformes, insolúveis e com condutividade elétrica entre 2 S/cm e 400 S/cm. A dependência da condutividade elétrica destes materiais em função da temperatura e da concentração de PEDOT:PSS foi descrita pelo modelo de transporte de cargas variable range hopping (VRH-3D). Adicionando-se o material eletroluminescente (EL) inorgânico silicato de zinco dopado com manganês (Zn2SiO4:Mn) à matriz condutora de PEDOT:PSS/GPTMS foi obtido um compósito para a produção de dispositivos EL. Depositando-se este compósito EL sobre substratos de vidro contendo eletrodos transparentes de óxido de estanho e índio, foram obtidos dispositivos EL com tensão de operação de 30 V e eficiência luminosa de 1,3 cd/A. Além disso, a transmitância óptica e a resistência de folha de filmes do compósito condutor (PEDOT:PSS/GPTMS) foram avaliadas, demonstrando que este material apresenta propriedades compatíveis com a aplicação como eletrodo transparente. Por fim, foram produzidos dispositivos EL utilizando o compósito condutor PEDOT:PSS/GPTMS como eletrodos e o compósito EL PEDOT:PSS/GPTMS/ Zn2SiO4:Mn como material ativo. Com este experimento, foi demonstrada a possibilidade de fabricar dispositivos EL por rota líquida, onde o compósito PEDOT:PSS/GPTMS foi utilizado tanto para a fabricação dos eletrodos como para a produção do material ativo do dispositivo. / It is possible to fabricate light-emitting (LE) devices with LE composites as active material. These light-emitting composites are produced with a LE inorganic powder dispersed into a conducting polymer matrix. However, these composites are chemically unstable, limiting the deposition of soluble materials over it. To overcome this problem we developed a high-stability conductive matrix comprising the conductive polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) and the organic-silicate 3-glycidyloxypropyl)trimethoxysilane (GPTMS). Composites PEDOT:PSS/GPTMS with diverse weight concentrations of PEDOT:PSS were produced and used to fabricate high-stability films with electrical conductivity from 2 S/cm up to 400 S/cm. The charge transport in these conductive composites were studied as function of the temperature, as well as of the PEDOT:PSS concentration, and described by the 3D variable range hopping model. A light-emitting composite was produced adding to this conductive composite the inorganic electroluminescent powder Mn-doped zinc silicate (Zn2SiO4:Mn). Light-emitting devices, with turn-on voltage of 30 V and luminous efficacy of 1.3 cd/A, were produced with a coating of the developed LE composite done over glass substrates containing indium tin oxide transparent electrodes. Additionally, the optical transmittance and sheet resistance of films produced with the conductive composite PEDOT:PSS/GPTMS were evaluated showing that this material is suitable to fabricate transparent electrodes. Finally, were produced light-emitting devices employing the conductive composite PEDOT:PSS/GPTMS as electrodes and the light-emitting composite PEDOT:PSS/GPTMS/ Zn2SiO4:Mn as active material. This experiment has shown the fabrication of solution-processed light-emitting devices using the composite PEDOT:PSS/GPTMS as transparent electrode and as component of the active material.

Στην παρούσα ειδική ερευνητική εργασία μελετήθηκε η αγωγιμότητα σκότους και η μεταβατική φωτοαγωγιμότητα στο κενό και στον αέρα δειγμάτων υπό μορφή δισκίων συμπιεσμένης σκόνης διοξειδίου του τιτανίου (με την εμπορική ονομασία Evonik-Degussa (P25)) και δειγμάτων UP25 που προέκυψαν μετά από ανάμιξη σκόνης P25 και ουρίας (urea NH2CONH2) σε αναλογία βάρους 1:1, και τα οποία ψήθηκαν για 1 ώρα στους 450oC. Κατά το ψήσιμο καίγεται η ουρία και τροποποιεί την επιφάνεια του TiO2. Η αγωγιμότητα σκότους του δείγματος UP25 είναι μεγαλύτερη στο κενό από την αντίστοιχη του P25, γεγονός που αποδίδεται στην παρουσία της ουρίας, η οποία εισάγει κενές θέσεις οξυγόνου που δρουν σαν δότες ηλεκτρονίων. Στον αέρα η αγωγιμότητα σκότους του δείγματος UP25 είναι μικρότερη από την αντίστοιχη του P25 και αυτό οφείλεται στην προσρόφηση μορίων οξυγόνου στην επιφάνεια του TiO2, τα οποία δεσμεύουν ηλεκτρόνια και στην παρουσία αζώτου (από την ουρία), το οποίο εμποδίζει την προσρόφηση υγρασίας. Η φωτοαγωγιμότητα στο κενό φθάνει σε υψηλές τιμές και στα δυο δείγματα και εμφανίζεται ιδιαίτερα ευαίσθητη στο περιβάλλον. Η μεταβατική φωτοαγωγιμότητα αυξάνει με αργό ρυθμό στο κενό, φθάνοντας στον κόρο μετά από ημέρες και είναι σημαντικά μεγαλύτερη από αυτήν στον αέρα. Η «αύξηση» και η «μείωση» της φωτοαγωγιμότητας στον αέρα είναι πιο γρήγορη από την αντίστοιχη στο κενό και στα δυο δείγματα λόγω επανασύνδεσης. Στον αέρα η διαδικασία της επανασύνδεσης είναι ιδιαίτερα έντονη στο δείγμα UP25, καθώς η παρουσία του αζώτου μειώνει δραματικά την φωτοαγωγιμότητα λόγω της δημιουργίας μεγάλου αριθμού κέντρων επανασύνδεσης. / In the present master thesis, dark conductivity and transient photoconductivity in vacuum and in air were studied in samples of titania powder P25, which is a commercial product of Evonik-Degussa, and of UP25, prepared by mixing P25 and urea (NH2CONH2) powders in 1:1 weight ratio and consequent calcinations at 450 oC for 1 hour, in the form of pellet. The dark conductivity of UP25 is greater in vacuum than the corresponding one of P25 and this effect is attributed to urea’s presence, which introduces oxygen vacancies, that behave like electron donors. The dark conductivity in air of UP25 is lower than the corresponding one of P25, which is attributed to oxygen molecules adsorption on TiO2’s surface, which act as electron scavenger and nitrogen’s presence (by urea), which prevents water’s absorption. Photoconductivity in vacuum reaches very high values in both samples and is sensitive on the environment. Transient photoconductivity rises slowly in vacuum, saturating in days, and is much larger than that in air. The rise and the decay of the photoconductivity in air are faster than in vacuum for both samples, due to recombination. In air, the recombination process is significant mainly in sample UP25 since the nitrogen presence creates a large amount of recombination centers causing an important decrease of photoconductivity.

Electrical conductance in the ferromagnetic insulating (FMI) phase of manganites has been experimentally investigated. The investigations were performed on single crystals of compositions La0.82Ca0.18MnO3 and Nd0.7Pb0.3MnO3. The nature of electrical conductance is determined to be Shklovskii–Efros variable range hopping (SE–VRH). Further, at high bias levels, non–linear conductance (NLC) is observed. A “hot electron” model, that quantitatively explains the bias and temperature dependence of the NLC, consistent with the SE–VRH nature of electrical conductance, is presented. The limits of validity of the model are discussed.
