Effect of temeperature stress and water shortage on thousand grain weight of selected winter wheat varietes
Hlaváčová, Marcela ; Pohanková, Eva ; Klem, Karel ; Trnka, Miroslav
The aim of the presented study was to assess the effect of high temperatures and water shortage during anthesis on thousand grain weight (TGW) of two winter wheat varieties (Tobak and Pannonia). In addition, numbers of grains per spike were also assessed. The six growth chambers were used to simulate heat stress conditions within following gradient of temperature maxima: 26 degrees C (control chamber), 29, 32, 35, 38 and 41 degrees C. The relative humidity (RH) course and photosynthetically active radiation (PAR) intensity were controlled via protocols. Additionally, drought stressed (dry) and well-watered (wet) treatments were established within each growth chamber. The plants were removed from the growth chambers after 14 days and they were left until a full maturity, exposed to actual weather conditions. The TGW at 14% moisture were evaluated for particular treatments within both winter wheat varieties. TGW was generally more affected by high temperatures under drought stress than in well-watered conditions. The results revealed that Pannonia TGW was much more affected by the water deficiency in combination with high temperature (particularly 38 and 41 degrees C) than Tobak TGW.

MADEJOVÁ, Nina
Presented bachelor work set the target to review and evaluate the eating habits of children with preschool age. Research was carried out in chosen nursery school MŠ Palackého in years 2011/2012 and 2012/2013. Particularly 42 children (22 boys and 20 girls) were concerned in this survey. Age category was from 5 to 6 years. Generally the research was divided in three main parts. First part of bachelor work was based on snack and lunch evaluation from the point of view of macronutrients and micronutrients content followed by comparison with standards of particular age category. Next part of research includes the individual children Body Mass Index (BMI) evaluation taken at the beginning and at the end of the research together with the setting of percentile. Third part contains the study of eating habits outside the school based on questionnaire analysis. The result show that the energy intake from school meals did not exceed the 50% of boys recommended daily allowance and 55% of girls recommended daily allowance. Fat intake wasn?t within the norms either. Recommended daily allowance was fulfilled at 39% in case boys? case and 43% in girls? case. Carbohydrate was below the recommended average in case of boys but at the same time it reached the recommended level in girls? case. Contrarily the level of proteins was fulfilled highly above recommended norms of more than 60%. Level of calcium was also unsatisfying and it only reached the level of 24,5% of daily recommended level. Level of Iron (Fe) and Riboflavin (B2) was normative.

Evaluation of Body Composition of Soccer Players
Tvaroh, Miroslav ; Štochl, Jan (advisor) ; Chytráčková, Jitka (referee)
Název: Hodnocení tělesného složení hráčů fotbalu. Title: Evaluation of body composition of soccer players. V této diplomové práci jsem sledoval vliv pohybového zatížení na tělesné složení hráčů fotbalu během jedné sezóny na podkladě antropometrického měření. V minulosti se již mnoho studií zabývalo analýzou různých parametrů u hráčů fotbalu (včetně antropometrických), ale jen několik z nich sledovalo antropometrický vývoj během takto dlouhého období. Cílem bylo zjistit změny ve složení lidského těla mezi měřením na začátku sezóny (5.1.2005), průběžným (1.5.2005) a konečným měřením (15.8.2005). Během celého období sledování docházelo k trvalému snižování údajů o váze a Body Mass Indexu. S výjimkou řasy nad hřebenem kosti kyčelní, se tloušťka kožních řas zmenšovala od prvního měření. Významné změny byly pozorovány u procentuálního úbytku tuku naměřeném na konci sezóny v kontextu s předešlými měřeními. Během měření byl také zaznamenán nárůst hmotnosti kostí a svalů. Klíčová slova: antropometrie, složení těla, kožní řasy, fotbal 6

Simulation of circuit breaker maglatch dynamic behaviour
Konšel, Ladislav ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
This work includes the theory of circuit breaker construction and is focused mainly on overload function. It mainly deals with electronic circuit breakers, i.e. equipped with an electronic trip unit. The work is focused on the part of trip unit - maglatch of trip unit. For the purposes of simulation, the geometric model is created. Maxwell program is used for the simulation. The work describes the options for conditions input which are necessary for simulation. Using the distribution of magnetic field intensity and magnetic flux density in the section of trip unit maglatch is determined by the simulation. Furthermore, the force effects acting on the armature of the maglatch are calculated. Force values and the directions acting on the armature are determined by changing the simulation parameters - shift of the armature and coil current. Simulations are performed both for steady-state and for dynamic simulation – movement of armature is taken into account. The supply source for the maglatch is created by an external circuit.
