Early trichinosis disease – characteristics and evaluation of known available detection methods.
Janáček, Martin ; Farkač, Jan (advisor) ; Nakládal, Oto (referee)
Trichinellosis is a worldwide serious disease transmittable from animals to humans. The disease agent is Trichinella spp., which belongs to the phylum of parasitic nematoda called Nematodes. There are 12 genotypes of Trichinella currently known but the most important for the Czech Republic and neighboring countries are T. spiralis, T. britovi and T. pseudospiralis.
Man can be infected by ingestion of raw or undercooked meat of infected animals. Treatment is very expensive and can be fatal, therefore a great emphasis is placed on prevention, especially control of animal carcasses which are intended for human consumption. The most famous method, also approved by law, is the digestive method, however there are many other methods for testing the presence of a parasite or for specification of genotype.
This paper mainly deals with comparison of known and available methods of detection of trichinosis originators. Furthermore this paper gives character description of majorgenotypes of Trichinella.

Strenght, fracture and fatigue properties of base materials and weld joint of inflow piping to water turbine (PART I - Weld plate to plate)
Dlouhý, Ivo ; Kruml, Tomáš ; Čupera, Pavel ; Chlup, Zdeněk ; Šiška, Filip
Sets of strength, strain, fracture toughness and fatigue properties are summarised in the report characterising the base material, heat affected zones and weld joint material of steel used in water turbine system. Data obtained from 30 mm sheet materials and its weld joint are given. Tests have been carried out in agreement with recent standards and loading curves for finite element calculations have been also supplied. Crack resistance curves have been also generated by unloading technique at 0 and +20°C. Tests of compact tensions in transition regions enabling to determine reference temperature have been carried out. There are also data from fatigue tests, namely cyclic response and fatigue life curves, for the same materials.

Use of image analysis in the monitoring of critically endangered species Spiranthes spiralis
IPSER, Zdeněk
A population of an endangered orchid species Spiranthes spiralis was discovered in 1980 in the National natural monument Pastviště u Fínů in village Albrechtice, near Sušice. Since 1985 the number of flowering individuals of this population has been regularly monitored. Since autumn 1998 all the specimen found there have been marked and biometrically measured. Since the beginning of monitoring, big fluctuations in the number of flowering specimens or in survival of the individual plant rosettes have been observed among the years. The aim of this thesis was to design the so called index of shading and to verify the possibility of its use to explain some phenomena of plant population dynamics. The index was designed with image analysis and biometric data. The hypothesis has been tested, that the basic variable determining the plant{\crq}s fitness (survival, flowering, vegetative propagation etc.) is the rate of shading by neighboring vegetation (expressed with the index of shading). It has been found that the effect of shading on flowering is not significant or hidden by other factors (such as the course of the weather in the season etc.). The size of the leaf area affects the probability of flowering, number of blooms and height of the inflorescence stem. My thesis also focused on costs of flowering, survival probability (since 1998) and flowering dynamics (since 1986).

Strength, fracture and fatigue properties of materials and weld joints from feeder piping of water turbine
Dlouhý, Ivo ; Kruml, Tomáš ; Čupera, Pavel ; Chlup, Zdeněk ; Šiška, Filip
Sets of deformation, strength, fracture mechanical and fatigue properties of base materials and weld joints from feeder piping of water turbine is summarised in the report. There are data from 30 mm thick steel sheet and weld joint of this sheet with the casting part. R-curves have been also measured by loading - unloading method at room temperature and at 0°C. In addition tests of CT specimens in the upper shelf and transition region have been carried out with the aim to specify the lowest (conservative) value of the fracture toughness. Fatigue tests are reported too, mainly based on cyclic response curves and life time curves of the base material and heat affected zone of the weld joint between sheet materials.

SMSystem for Scoliosis
Hubertová, Ivana ; Smíšek, Richard (advisor) ; Jandová, Dobroslava (referee)
The practical part describes the progress of research on a group of 6 volunteers with a diagnose of the scoliosis. 8 static and dynamic tests were used to test the effect of SM- System - to assess differences of thoracolumbal triangles, to asess differencess in shoulder heigh, for measurement of the distance from the knee to the groung in a sitting position, for measurement of the distance from acromion to the ground lying on the bed, to test the difference in standing on two scales, to test standing on one leg, to verify the involvement of latissimus dorsi spiral during exercise and to verify the involvement of the deep stabilization system during exercise. In the second part the efect of spiral stabilization was verified through examination in the diagnostic and therapeutic kinesiology computer system. In the third part the influence of SM-System exercise was assessed on subjective perception of proband pain. Practically all tests with the spiral stabilization were proved as successful. Thus it was shown that SM-System exercise has a promising effect to the patients with scoliosis.
