Fenolické látky vo vybraných rastlinných druhoch
Boško, Rastislav
This diploma thesis deals with the analysis of phenolic compounds such as phenolic acids and flavonoids in selected plants, such as ribwort plantain (Plantago lanceolata L.) in which the content of chlorogenic acid, caffeic acid, verbascoside, ferulic acid, rutin and quercetin was monitored. The content of chlorogenic acid, coffee acid, routine, hyperoside, isoquercitroside, tiliroside, quercetin and kaempferol was monitored in small-leaved lime (Tilia cordata Mill.) In addition, the content of chlorogenic acid, caffeic acid, coumaric acid, rutin, hyperoside, isoquercitroside, quercetin and kaempferol was monitored in marigold (Calendula officinalis L.). Also the content of chlorogenic acid, coffee acid, rutin, hyperoside, isoquercitroside, quercetin and kaempferol was monitored in elderberry (Sambucus nigra L.). Similarly the extraction of phenolic compounds from these plants was carried out and subsequently subjected to chromatographic analysis on a UPLC liquid chromatograph with a PDA detector at the Research Institute of Brewing and Malting, Plc.
Zhodnocení rodu Tilia L. z pohledu zahradní a krajinářské architektury =: Evaluation of the genus Tilia L. from the point of view of garden and landscape architecture /
Ottomanský, Ondřej
The present dissertation entitled "Evaluation of the genus Tilia L. from the point of view of garden and landscape architecture" was elaborated between October 2007 and February 2018. The work is divided in the standard way for this type of final paper consisting of introduction, background sources, aims, literature survey, methodology, materials, results, discussion, conclusion, literature review etc, contains 339 pages of text, 437 pictures, 99 plates, 7 tables which are place in the text, especially in part of results. This work brings information about 23 cultivated species, the most important hybrids and more than 240 cultivars of lime trees. It summarizes information about the origin of the cultivated specimens, their characteristics and their description, accompanied by a large number of pictorial materials. There is summary of current situation from the point of view of systematic botany, name and origin of plants in culture, grown assortment and introduction of trees. The author also deals with issues of important lime trees collections, history of use in objects of garden art, but also focuses on the etymological origin of lime, symbolism and folk culture. From the point of view of the general characteristics of the genus, the work contains a brief outline of the genus structure, the geographical distribution, the important user and ecological-cultivating properties. From the described assortment has been determined basic assortment which has to be widely known and available: Tilia cordata, Tilia platyphyllos, Tilia tomentosa, Tilia tomentosa 'Petiolaris', Tilia ×euchlora, Tilia ×europaea. Based on the experience of growing in Oplany Klíče, an additional assortment has been set with regard to the needs of garden and landscaping architecture. From the phenological observations in Oplany Klíče has been made tables with sequence of unfolding leaves and flowering.

Thyme, linden and cuban oregano are plant that have positive effect of upper respiratory tract infections. The most common are used in the form of teas and syrups. In this thesis were analyzed methods, which are used to specify substances in plants. It describe methods like stem distillation, SPME and GC/MS. The main aim of the thesis was found out subsances, which occur in herbs. Thymol was the substance which was found in every analyzed herb. The thyme contain o-cymen, in mixture of thyme was proofed thymol, borneol, 1-octene- 3- ol, linalol, estragol a 4- terpeneol. The linden has substances estragol a - terpinen. Characteristic substancies od the mixture of linden were o-cymen, estragol a - terpinen. In the cuban oregano were proofed – pinen, camphor, - terpinen. The method SPME was used to analyzed substances in syrup and main substances were thymol a -elemen.
Representations of ideological and national-formation consciousness in journals for children in the inter-war period
Bachelor's thesis will be dedicated to description and comparison of Czech children's magazines published during the interwar period, specific trait of which was their affiliation to different clubs, organizations or the church.

It will also observe the extent of ideological agitation in each periodical or eventually the symbols of national consciousness, which it will interpret and compare as possible representations of various ideological goals.
Porovnání anatomické a morfologické stavby iterujících a reiterujících letorostů lípy (Tilia sp.)
Cristini, Valentino
These days, within Arboriculture are wather sprouts a very important discussed topic, so it is important to know their qualities and their main differences from normal (iterating) shoot. In the bachelor thesis are compared anatomical and morphological characteristics of normal (iterating) and epicormic (reiterating) annual shoots of selected individual of Tilia platyphyllos (largeleaf linden) in Brno, Czech Republic. By statistical correlation was found that there are demonstrable dependencies between different stem segments (pith, xylem, phloem and primary cortex) either at normal or at epicormic annual shoots.
Design of mixing ratio of two quarried aggregates fraction 0/4 mm for readymix concrete
Jastrzembská, Alena ; Dorazilová, Irena (referee) ; Bodnárová, Lenka (advisor)
This diploma thesis describes with mixing ratio of two kinds of small quarried aggregate for the production of ready mix concrete. The theoretical part summarizes the requirements of Czech technical standards to individual components of concrete, particularly the requirements for fine aggregates. In the practical part were designed the recipes for three classes of concrete and was done checking the properties of concrete in fresh and hardened state. Based on the results were determined the optimal mixing ratio of fine aggregate from location Smiřice and Lípa.
Srovnání vlastností druhů rodu Tilia rostoucích v alejích v okolí Hořic
Kráčmar, Jan
The goal of my thesis was to compare characteristics of two species of the genus Tilia growing in alleys close to Hořice town. Between Tilia platyphyllos Scop. and Tilia cordata Mill. following attributes were compared: stem height, stem diameter, the occurrence of knobs on the stems and its dependency on both species and treatments given to the tree. The values were obtained by tree measurements and processing the data into tables and graphs. The comparison showed that Tilia cordata Mill. reaches on evaluated locations higher stems than Tilia platyphyllos Scop. Tree diameter is affected by treatments: untrimmed Tilia platyphyllos Scop. individuals have bigger diameters. Tilia platyphyllos Scop. suffers more from knobs. Trimmed Tilia platyphyllos Scop. individuals suffer more from knobs in upper third of stems than those of Tilia cordata Mill.
