Steam boiler with grate firing burning mix coal and wood (mixing ratio 30/70-wood)
Dvořák, Aleš ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This diploma work attends to presentation of steam grid boiler for wood and brown coal burning in scale (30/70-wood) in load 60t/h, with parametres of outgoing vapour p=7MPa, t=490°C. The work is splitted to several chapters. At the beginning I’m going to make stechiometric calculation and entalpic calculations of air and compustion gas. After that I’m going to calculate heat balance, losses of boiler and set heat efficiency of boiler. Then I’m going to suggest combustion chamber of boiler and make heat calculation. After suggestion of combustion chamber I’m going to set proportions of pulls and heat-delivery surface. In last chapter I’m giong to check heat balance. Inclosure of my work contains drawing documentation of steam boiler.

Steam boiler for burnig mix of wood and sub-bituminous coal(mixing 50/50).35t/h
Chmelíček, Jiří ; Kohout, Přemysl (referee) ; Skála, Zdeněk (advisor)
This master´s thesis deals with the constructional and calculation design of the boiler for burning wood and sub-bituminous coal. The work is divided into several parts. First, stoichiometrics calculation and enthalpy calculations of air and flue gas are performed. It is calculated heat balance of the boiler, the boiler losses and the thermal efficiency of the boiler is determined. After designing the combustion chamber thermal calculation is made. Then, the dimensions and individual heating surfaces are proposed. At the end of the calculations are controlling the overall energy balance.

Test of medicaments perspective for exploitment at the fishing profession
SCHEINER, Pavel
The aim of the study was to assess the effects of orally applied praziquantel on the treatment efficacy against most abundant tapeworms (Atractolytocestus huronensis Anthony, 1958 and Khawia sinensis Hsü, 1935) of common carp (Cyprinus carpio Linnaeus). Naturally infected fish (one-year-old; K1+) were divided into 3 trial groups containing 17 specimens and administered with praziquantel mixed in heat-treated amyloid vehicle (in doses of 50 mg.kg-1 body weight). In 3 groups of control, the fish were administered amyloid vehicle only. Fish were examined by using of gut dissection 2, 4 and 6 days after administration. At 48 hours post-treatment, significantly lower prevalence of both parasites was found. The invasion of A.huronensis was fully eliminated in all fish after 96 hours whereas some specimens of K.sinensis still persisted in the gut of few fish. The full elimination of both parasites was observed 6 days after administration. Our results showed that elimination of K. sinensis takes longer than elimination of A.huronensis. The dose of 50 mg kg-1 of orally applied praziquantel is effectual to control A.huronensis and K sinensis infections in common carp successfully. The effect of oral applied praziquantel on the hematology and biochemical parameters blood of common carp (Cyprinus carpio L.), infected by the tapeworms Atractolytocestus huronensis and Khawia sinensis was the object of analyse. It was the partial goal of the work. The infected fishes were divided to the six groups. The praziquantel was applied stirred in amyloid vehicle in dose 30 mg/kg of quick materiality for two groups and for two to other groups in dose 50mg/kg of quick materiality. Only clean amyloid vehiculum was applied to two control groups. Blood taking and resulting patoanatomic investigation was effected 24 and 96 hours after application of praziquantel. Results of hematology investigation of blood obtained 24 hours after the application point on significant fall (p< 0,01) of the number of erythrocytes, hemoglobin and hematocrit in both groups E1 and E3, which achieved the original surface after 96 hours. The significant upsurge (p<0,05) of the surface serum hepatic enzyme ALT was recorded after 96 hours.

Roupcová, Pavla ; Schneeweiss, Oldřich
Changes in the phase composition and the mean particles size of nanocrystalline Zr-Fe powdered prepared by mixing of pure ZrO2 and iron oxides were investigated in dependence of the heat treatment in vacuum and hydrogen atmosphere.

Synthesis of Heterostructure Particles by CVD Method in a Tube Flow Reactor
Moravec, Pavel ; Smolík, Jiří ; Levdansky, V.V. ; Keskinen, H.
Powders of mixed or heterostructure fine particles are of even greater value than the single component ones. During last decade we prepared single component fine particles of silica, alumina, titania and zirconia by decomposition of organoelement precursors in an externally heated tube flow reactor. On the basis of experience with the synthesis of single component particles we prepared mixed or coated multicomponent particles Al2O3-SiO2, TiO2-SiO2 and ZrO2SiO2 by simultaneous decomposition of two precursors in one reactor.

Ekonomika variant skladeb konstrukcí dřevostaveb
Kuchař, Marek
Thesis is processed in the form of marketing mix and it is bent on own proposal compositions of construction wood constructions that are fit for attic log house. Individual particulars of compositions are comminuted in the work are hand-lettered comminuted. Suggested composition are advised by heat technical and acoustic characteristics according to valid recipes doctoring this problems. Fire fundamentals near single compositions are also solved. Suggested composition were to be further on fancieds on surface 1 m2. Compositions from free companies implementing log house were evaluted. Near suggested compositions was buckthorn their publicity and was suggested fit marketing strategy.

Pěstebně-ekonomická analýza listnatých mlazin s různou příměsí dubu vzniklých kombinovanou a umělou obnovou
Zapletal, Miroslav
Abstract of the work This thesis deals with the growth characteristics of oak at the stage of coppice that was based in different variants depending on the type of mixing and method of recovery (combined, artificial). The research areas are located in Kostelec woods which is about 7 km from the Holešov town in the district of Kroměříž. In total there are five areas evaluated, the area (I, II) Option 1 - monoculture and area (III - V) Option 2 - mixed (combined and artificial regeneration). Crops were chosen so as they are the same age, only the area V is older and without silvicultural intervention. The measurement of tree species was carried out in each alternative on the pad of 3.14 m2 (r = 1 m) in a regular grid of 5x5 m. On each space were measured height, výčetní tloušťka a cenotické postavení of all trees and quality of the treetop. Collected data are recorded in tables and graphs. The results of the thesis show that the oaks in option (1) in all the above parameters are better than in the variant (2).
