Rheological characteristics of untreated and thermally modified wood under long-term loading in bending
Berková, Tereza ; Borůvka, Vlastimil (advisor) ; Ruman, Daniel (referee)
Heat-treatment belongs to the most ecological methods of wood preservation methods and increase of its natural stability in exposition to outdoor conditions. Research of mechanical properties opens new possibilities of thermowood usage in general.
Wood appertains to viscoelastic materials and due to long-term loading creeps. There currently rise both elastic deformation, deformation elastic in time and plastic deformation. Partially there are irreversible changes due to stress even after unloading.
This work presents first insight to the matters of thermowood rheology and inspects its behavior under long-term loading in bending. This paper compares ratio of these three types of deformation in untreated wood and thermally modified wood in seven different temperatures (140; 160; 180; 190; 200, 210°C). The samples were exposed to 600 hours applied loading covering 40% of ultimate stress (modulus of rapture). Test were performed under constant conditions in special creep units in conditioning kiln. Increasing deformation under constant load was analyzed by Burger rheological model.
The results show that samples treated under lower temperatures (140 and 160°C) exhibit greater creep than untreated wood. This result is positive for structural usage of wood. On the other hand the samples treated under higher temperatures levels (200 an 210°C) display deterioration of mechanical properties. This is due to changes in wood structures caused by heat-treatment.
The most important impact of this work goes to future research of this field. Next development has to apply for the best quality of samples and also select rather prismatic parallelism than transversal one. Also application of 40% ultimate stress loading appeared as too high and together with wood defects led to destruction of samples.

Evaluation Principles: Effective evaluation and financing system for research, development and innovation
Münich, Daniel
The objective of Ipn project “Effective evaluation and financing system for research, development and innovation“) is to replace from 2015 the existing Methodology of evaluating the results achieved by research institutions with a more effective system of institutional evaluation based on the international quality standards. The new evaluation in the form of informed peer-review will reflect the Ipn Audit recommendations as well as Long Term Evaluation Principles adopted by RVVI (Research, Development and Innovations Council). The new system will combine quantitative and qualitative evaluation of outputs and contributions of the creative activity of research institutions with clear and future oriented indicators in order to facilitate evaluation of their development dynamics, evaluate their outputs from the point of view of their quality, relevance, impact and effectiveness while respecting the departmental and institutional differences. It should enable periodic evaluation of the performance of Czech Research, Development and Innovation system as a whole and of its individual components in comparison with the global standards. The evaluation results should facilitate strategic management on the level of public administration as well as on the level of individual institutions and their departments. The evaluation process should be resistant to nepotism and should be supported by high quality international expert evaluators and bibliometrical criteria.

Effective System of Evaluation and Financing of Research, Development and Innovations Project: hopes and expectations
Hronová, Stanislava
Since 2004 the methodology of evaluating research and development results (later: methodology of evaluating results achieved by research institutions) applied in the Czech Republic has gone through many revisions which however have not changed the principles of what was devised as a not very suitable system. The deformations resulting from such evaluation became fully apparent when the results were directly linked to the distribution of funds provided for the long term development of a given organisation. In 2011 the Council for Research, Development and Innovation decided on the basis of discussions within expert community about the fate of evaluation methodology, negative effects it had on research institutions, partial outputs (at that time) of the RDI System International Audit in the Czech Republic to adopt the Long Term Principles of Evaluating the Research Institutions Results. These principles are the backbone of IPn Methodology Project that should provide the scientific community as well as the public administration with an instrument of evaluating research institutions and with the system of research and development in the Czech Republic respecting international standards and departmental differences, based on quantitative and qualitative criteria

The analysis and outcome of the thesis are believable to help cellphone producers in Vietnam market to understand more about their clients and to set up feasible business strategies for increasing business output.
4. Methodology
Theoretical part of the bachelor thesis mostly presents about behavior theory, factors that affects behavior and the decision-making process of customers.
The practical part focuses on the research methods by using quantitative and qualitative research methodology together. By creating an online questionnaire (via social networks) with detailed questions related to the topic of thesis will be conducted and aimed to those who are student at Thang Long University in Vietnam. The data collected from the questionnaire which is filled in by students on the internet will be analyzed and recapitulated to give out objective assessment on consumer behavior to a particular product.
5. Main Findings
The responses of students at Thang Long University to the consumer behavior on mobile phone market questionnaire reveal that:
Information of sample: The questionnaire result indicated that 100% of students had mobile phones. It means that mobile phone is very popular in any social class as well as is very essential in the student life.
Through the survey, student who are living in the city accounted for 76%, is higher than in country side with 24% and the financial condition usually flutuates from 3 million to 4 million Dong, which accounted for 52%. Almost students in Viet Nam have had a part-time jobs to be more self-sufficient and independent on their family. That is why part-time jobs accounted of highest proportion with 54% of the 50 sample studied. The other incomes students come from their family with 26% and 12% is scholarship they received from university).
Mobile phone consumer behavior: Through the study of student consumer behavior on mobile phone market in Vietnam, the main results are shown as the following:
Understanding cognitive demand: The study result indicated that most of students realized the importance of mobile phone in their life. Student uses mobile phone for many different purposes, but almost students use mobile phone to serve works as well as to contact with their friends (89%). Besides, they did make lots of researches before purchasing a mobile phone. In which, the most reliable resources of information are from family, friends, and sellers (44%).
Evaluating plans: When students decided to buy a new mobile phone, they would mostly care about the quality (90%) and the useful on selecting products. Black and white are two basis colors that selected by students (33% and 35% respectively). Student also concerned with long battery life and the good at call quality, which respectively accounted for 64% and 58%.
Decision-making: The student tends to choose of buying a new mobile phone at store with 68% and they can accept to buy them at price from 5-7 million Dong to over 7 million Dong because of high operation as well as the variety applications. It can be seen from the survey that student using the Internet as the main activity, which accounted for 52%. Iphone (Apple) and Samsung are the favorite brands of student when selecting to buy mobile phone.
Post-purchase behavior: Mobile phone markets have launched the beautiful models, diversity designs as well as an important functions have been upgraded leads to change behavior consumer on purchasing phones. The results showed that there was a remarkable amount of student felt normal with their current mobile phone (34%), it means that they might be change a new phone in next time. Students who not satisfied with their mobile phone accounted for 10% because of broken or out of order.
6. Conclusion and the limitation of the study
In conclusion: From the result of study, it could be said that student behavior in purchasing and using a mobile phone was mostly and highly influenced by the technological status of device. The results of this study also help the businesses to understand the consuming behavior of students and have more appropriate marketing strategies to increase the consumption of mobile phones.
The limitation of the study: The study of consumer behavior on purchasing a mobile phone of students in Viet Nam is a long process and requires a lot of analysis. Meanwhile, these mainly methodology of this study is to approach direct interviews by created a survey form online with some questionnaires table and sent them to students who studying in Thang Long University via Internet (Facebook, department page, created group chat) without combination with other methods to better understand all of issues on students consumer behavior. In a reality, people can choose a mobile phone based on many criteria, however, this study just focused on basic criteria which widely has known already.

Effect of long term fertilization on behalf fraction of nitrogenous substances in fodder alfalfa
Matunová, Jana ; Hakl, Josef (advisor) ; Josef, Josef (referee)
The representation fraction of crude protein in forage legumes significantly influences nitrogen utilization by ruminants. Similar researches were not previously realized. The aim of this thesis is valorizing of long-term fertilization on vegetation structure and representation fraction of crude protein in forage alfalfa. Experimental measurements were carried out at the Research Institute of Crop Production in Prague, Ruzyne. The crop of alfalfa was in the context of long-term fertilization experiment established in the spring of 2013. An attempt with a sown variety Moravia is arranged in the scheme of split-plot. Samples were taken only from the first cut in 2015, each of one line of 50 cm in every block. In the experiment are evaluated four contrasting versions of fertilization (unfertilized control crop, growth fertilized by organic, by mineral and by combination both types of fertilizers). Each variant was repeated for three times. This thesis showed that long-term fertilization influences the parameters of the structure stands of alfalfa. We observed a greater proportion of L/m2 in fertilized variants, an also these stems were higher. Additionally, we observed higher profits, which were in correlation with the sinking share of representation leaves in the growth. Analysis showed that the behalf of nitrogenous substances and individual crude protein fractions is not constant, but is changeable during different variants of fertilization. Unfertilized crop contained on the average 221 g/kg dry matter of nitrogenous substances. The highest protein coken were at crops fertilized organically, 248 g/kg. In the control variant was detected on the average of 328 g/kg of fraction A. This fraction was most abundantly represented in growths with mineral fertilizers, 418 g/kg. On the contrary variant fertilized by combination had the lowest contents of fraction A, 307 g/kg. The highest concentration of B1 was found in mineral fertilized crops, 75 g/kg. For nitrogenous fraction B2 was detected the
highest concentration in crop fertilized by combination of mineral and organic fertilizers, 531 g/kg. For nitrogenous fraction B3 was found the highest concentrations in mineral-fertilized growths (NPK). This value is 24 g/kg. By nitrogenous fraction C was found highest concentration in control growth and crop fertilized with mineral, 80 g/kg. On the contrary, in crops fertilized organically was measured lowest value, 67 g/kg. We can conclude from the results, that the best profile fraction of crude protein has variant fertilized with a combined manner.

Effect of internal factors on milk production and quality
Zvonař, Miroslav ; Toušová, Renata (advisor) ; Stupka, Roman (referee)
The theoretical part of my bachelor's thesis was focused on describtion of milked breeds of cattle and its breeding technique and technology, as well as diet and feed. I was trying to expleain effect of some inner factors such as genetic factors, health condition, reproductive indicators, lactation number and mastitis, on milk production and its quality. In practical demonstration, held in the Meclovska zemědělská Ltd. company on the farm Srby, the influence of these inner factors on milk production and its quality was observed.
Firstly, the research was focused on milk constituents proportions: protein, fat percentage and the number of somatic cells. Secondly, it was focused on performance evaluation during normal lactation, the age of the cattle when first calving, meantime, insemination interval and post partum interval. Data were found in the cattle performance inspection results from January 2015 to December 2015.
On this particular farm Srby, there are circa 660 cows of the Holstein cow breed. In this reported period the average volume of milk was 10 400 kg during normal lactation with the percentage of proteins 3,44 % and 3,84 % fat. The average amount of somatic cells was 354 thousand in 1 ml of milk.
Randomly chosen group of 100 pieces of cattle was selected for further research. The group was divided into two groups of 50 pieces of cattle. In the first group there were 50 first calf cows and in the second group there were cows on the second or higher level of lactation. The first group of first calf cows managed to produce in average of 9 521 kg of milk with 3,86 % of fat and 3,36 % of proteins. The average amount of somatic cells in 1 ml of milk was 72 thousand. In the second group consisted of cows on second or higher level of lactation, there were different results as the average milk production was higher 11 790 kg with average of 3,75 % of fat and 3,35 % of proteins. There was significantly less somatic cells in 1 ml of milk. The result was surprisingly great with 46 thousands somatic cells in 1 ml of milk.
First calf cows during the first calving were 741 days old on average. The average insemination interval in the first group of first calf was 72 days long and the average post partum interval was 102 days long. In the second group of cows on higher lactation level the average meantime was 396 days. The average insemination interval was 80 days and the average post- partum interval was 117 days, which is quite long and it could be implying to bad result, but we should consider high efficiency of observed dairy cows.
