Mafic and intermediate intrusions accompanying peraluminious granites of the Krušné hory Mts.batholit
Holečková, Pavla ; Jelínek, Emil (advisor) ; Ackerman, Lukáš (referee) ; Leichmann, Jaromír (referee)
Mafic and intermediate intrusions commonly accompany Variscan granitoid plutons in Europe. They are documented from different localities of Iberian Peninsula, from the French Massif Central, Schwarzwald, from different parts of the Bohemian Massif, in Romania, Greece, Corsica and Sardinia. They comprise wide petrographic varieties from quartz gabbros, diorites, granodiorites to monzonites. They usually constitute small bodies or veins, they often occur as mafic microgranular enclaves (MME) in granodiorites and in some granites. Dioritic intrusions are characterized by a relatively high amounts of lithophile elements (Rb, Sr, Ba, Cs, LREE), and they are simultaneously high in compatible elements (Ni, Cr, V a Co). Their isotopic ratios 87 Sr/86 Sr are in all compared locations similar and are close to the Bulk Earth (0.704 - 0.708). εNd values show larger scatter, some intrusions have more crustal composition (to -8), on the other hand, another intrusions have εNd positive, that points to a contribution of basic magma. The age of dioritic intrusions differs according to individual locality suggesting more than one magmatic episode. The oldest occur in the French Massif Central (361 - 365 Ma), whereas the youngest are documented in Iberia (312 - 310 Ma). The oldest mafic intrusions in the Bohemian...

Geochemistry and geochronology of mafic intrusions in the northern part of the Carlsbad pluton
Holečková, Pavla
ii SUMMARY In the NW part of Bohemian massif occur small bodies of mafic intrusive rocks. These rocks are called redwitzites and they include various rock types from diorites to quartz gabbros. They are always close to granites OIC (old intrusive complex). They are probably precursors of Late Variscan granitoid magmatism. Small body of redwitzites is situated near Abertamy (7 km NW of Jáchymov) in the western part of Krušné hory Mts. This body is inhomogeneous; it is formed by two types of mafic rocks. Both rocks distinguish in mineralogy and chemistry. First type, biotitic gabronorite, forms the western part of the body, another type, biotitic - hornblende quartz gabrodiorite, forms the NE part. The expressive sign of Abertamy redwitzites are flakes of brown biotite which can be as large as 2 cm. They are often poikilitic. Gabronorite is a fine-grained green-grey rock consisting of orthopyroxene, biotite, feldspar, quartz and hornblende. Most of the mafic minerals are altered to uralite. Accessories are represented by apatite, zircon, monazite, allanite and sphene. From the chemical point of view is gabronorite enriched in compatible elements (Mn, Fe, Mg, Ni, Cr, Sc, V, Ca, Co, Zn, Cu). Gabrodiorite is medium-grained rock and it is collored light gray. Its composition is similar to the gabronorite. It does...

Late consequences of knee injury.
Holečková, Pavla ; Eislerová, Iva (advisor) ; Kulhavá, Miluše (referee)
This thesis deals with the issue of knee injuries and gonarthrosis. The thesis has theoretical and empirical character. The theoretical section is divided into three main chapters. The anatomy of the knee joint is described in the first chapter. Second chapter deals with knee injuries; this part is focused on the injuries to ligaments, menisci, cartilage and patella. Gonarthrosis, its etiology, symptoms, treatment and prevention, is compiled in the last chapter. The empirical section contains the results of research. The research was performed as an anonymous questionnaire study. Respondents were older than 18 years and after the knee injury. The sample consisted of 102 respondents. The aim of the empirical section was to find out what kind of injuries the clients have experienced, their attitude towards the after-treatment of the injuries, their knowledge of gonarthrosis and whether they occupy themselves with its prevention. The results were processed into charts and graphs. The research show, that the most common injury is one to the anterior cruciate ligament. A third of the respondents does not follow the treatment regimen, most frequently they fail to walk on crutches or to wear a knee brace. More than 80% of respondents know the symptoms, but only 11,76% of respondents know stages of...
