3D printers
Göbel, Lukáš ; Synek, Miloš (referee) ; Pavlík, Josef (advisor)
Bachelor's thesis is divided into two parts. The first part deals with the general use of 3D printers in the industry, describes the pre-processing and post-processing operations and used materials. The second part is concentrated on the construction solution and describes each principle of the 3D printing machines, including their advantages, disadvantages and applications. Also some selected common printing technologies are mentioned with examples of their parameters and used materials.

Objectivity of gymnasts' achievements judging in relation by Code of Points Men's Artistic Gymnastics changes
Chrudimský, Jan ; Novotná, Viléma (advisor) ; Pavlík, Josef (referee) ; Strešková, Elena (referee)
Title: Objectivity of gymnasts' achievements judging in relation by Code of Points Men's Artistic Gymnastics changes The problem of our work is an objectivity of gymnastics way of ranking or judging. Analysis of results reached at chosen men's artistic gymnastics competition and also a method of gymnastics judging was used for solving purpose of our thesis. The evaluation of gymnasts achievements are realized by referees according to Code of Points (CoP) Men's Artistic Gymnastics (MAG), which are periodically changed. The purpose was verify possibility of determination degree of objectivity judging gymnastic performances in relation to changes rules of men's artistic gymnastics realized in years 2006, 2009, 2013 through analysis of gymnastics results in seniors and juniors categories reached on important international competitions. We used methods and techniques of statistical description for ordinal data; Sign test; Wilcoxon test; contingency table and sign diagram for contingency table. For evaluation rate of interrater concordance referees of panel "B" or "E" we used ICC and Pearson's correlation coefficient. For evaluation of bilateral discriminability of reached gymnastics results we used SEM and calculation of Critical Differences. In connection with changes of CoP MAG on monitored period...

The influence of stretching exercises on the range of joint flexibility in students PF UJEP in Ústí nad Labem
Kabešová, Hana ; Novotná, Viléma (advisor) ; Havel, Zdeněk (referee) ; Pavlík, Josef (referee)
THE INFLUENCE OF STRETCHING EXERCISES ON THE RANGE OF JOINT FLEXIBILITY IN STUDENTS AT JAN EVANGELISTA PURKYNĚ UNIVERSITY IN ÚSTÍ NAD LABEM The dissertation evaluates the influence of stretching exercises on the range of joint flexibility in students of the study programme Physical Education and Sport at Jan Evangelista Purkyně University in Ústí nad Labem. In total, 128 students aged 21 - 25 (78 women, 50 men) enrolled in the subject Basic Gymnastics took part in the experiment, conducted in the period from February to May of the academic year 2008/2009. Of these, 59 students were excluded by a physiotherapist - i.e. hypermobile men and hypermobile women as well as women with normal flexibility (excluded purposefully) subject to the results of the Thomayer test. In total, data from 39 men and 30 women were used. From April 2009, over a period of six weeks (before the end of the summer term tuition), an intervention flexibility programme including the Anderson static stretching method and the PNF stretching method by Sölveborn were applied for the research file. To evaluate the level of joint flexibility, the Sit and Reach Test and credit exercise to estimate joint flexibility were used. In a controlled interview, out-of-school activities were analysed, which contained stretching exercises with a...

Využití diagnostických metod pro optimalizaci výživy brambor
Pavlík, Josef
The bachelor thesis is aimed at the use of diagnostic methods to optimize the nutrition of potatoes in operational practice. The pilot field experiment was established in Lutopecny in the Zlín Region. The following variants were included in the experiment: 1. LAV + 8% urea solution, 2. ALZON 46 by Nmin and 3. ALZON 46 by Nmin + 8% urea solution. The first option reflects the traditional system of potato fertilization on the grower's land. On the second variant, the nitrogen nutrition of the potatoes was optimized according to the content of mineral nitrogen (Nmin) in the soil and the urea with the nitrification inhibitor (ALZON 46) was chosen. The third variant is based on variant n.2 and should be supplemented with foliar application of urea according to nitrogen and phosphorus content in plant biomass. Although the nutritional status of the crop was good, supplemental fertilization with 8% urea solution was applied. The average of total tuber yield was 30% lower in the traditional technology variant than in the nitrogen-optimized variants. Supplemental fertilization with 8% urea solution per sheet in option 3 did not cause additional yield increase because the nutrient status of the urea fertilization with nitrification inhibitor based on the Nmin content of soil was assessed as optimal. Based on one-year results, it is advisable to correct the nitrogen dose for potato fertilization after planting according to the mineral nitrogen content of the soil.
