Revitalization of Technical Museum Brno
Projekt se zabývá rozšířením expozice Technického muzea v Brně. Budova dnes nemá dostatečnou kapacitu na vystavení větších dopravních exponátů. Navržená expozice dopravy tvoří svou velikostí urbanistický komplex založený na osách. Svým velkým měřítkem prezentuje monumentální objekty tak, jako by se jednalo o sbírku předmětů velikosti hraček. Typologie je minimalistická a variabilní tak, aby byla schopna reagovat na různé požadavky scénografů nebo veřejnosti. Analytická část zkoumá vývoj muzeální expozice a její současné trendy.Project of revitalization of Technical museum Brno deals with extension of its complex. Museum has not enough capacity to shelter and expose all its large vehicles. The extension of transport museum is designed as an urban complex based on axes. The large architectural scale presents monumental objects as small as collection of toys. Typology is minimalistic and variable so it could react on various demands of exhibitions designers and public. Analytical part examines researches about museum exhibition's evolution and contemporary trends.
Spontaneous Firings of Carnivorous Aquatic Utricularia Traps: Temporal Patterns and Mechanical Oscillations
Aquatic species of Utricularia are carnivorous plants living in environments poor in nutrients. Their trapping mechanism has fascinated generations of scientists and is still debated today. It was reported recently that Utricularia traps can fire spontaneously. We show here that these spontaneous firings follow an unexpected diversity of temporal patterns, from “metronomic” traps which fire at fixed time intervals to “random” patterns, displaying more scattered firing times. Some “bursting” traps even combine both aspects, with groups of fast regular firings separated by a variable amount of time. We propose a physical model to understand these very particular behaviors, showing that a trap of Utricularia accomplishes mechanical oscillations, based on continuous pumping and sudden opening of the trap door (buckling). We isolate the key parameters governing these oscillations and discuss the effect of their fluctuations
Quite a few reasons for calling carnivores "the most wonderful plants in the world"
A plant is considered carnivorous if it receives any noticeable benefit from catching small animals. The morphological and physiological adaptations to carnivorous existence is most complex in plants, thanks to which carnivorous plants have been cited by Darwin as ‘the most wonderful plants in the world’. When considering the range of these adaptations, one realizes that the carnivory is a result of a multitude of different features.
Scope: This review discusses a selection of relevant articles, culled from a wide array of research topics on plant carnivory, and focuses in particular on physiological processes associated with active trapping and digestion of prey. Carnivory offers the plants special advantages in habitats where nutrient supply is scarce. Counterbalancing costs are the investments in synthesis and the maintenance of trapping organs and hydrolysing enzymes. With the progress in genetic, molecular and microscopic techniques, we are well on the way to a full appreciation of various aspects of plant carnivory.
Conclusions: Sufficiently complex to be of scientific interest and finite enough to allow conclusive appraisal, carnivorous plants can be viewed as unique models for the examination of rapid organ movements, plant excitability, enzyme secretion, nutrient absorption, food-web relationships, phylogenetic and intergeneric relationships or structural and mineral investment in carnivory
Female germ unit in Genlisea and Utricularia, with remarks about the evolution of the extra-ovular female gametophyte in members of Lentibulariaceae
Lentibulariaceae is the largest family among carnivorous plants which displays not only an unusual morphology and anatomy but also the special evolution of its embryological characteristics. It has previously been reported by authors that Utricularia species lack a filiform apparatus in the synergids. The main purposes of this study were to determine whether a filiform apparatus occurs in the synergids of Utricularia and its sister genus Genlisea, and to compare the female germ unit in these genera. The present studies clearly show that synergids in both genera possess a filiform apparatus; however, it seems that Utricularia quelchii synergids have a simpler structure compared to Genlisea aurea and other typical angiosperms. The synergids are located at the terminal position in the embryo sacs of Pinguicula, Genlisea and were probably also located in that position in common Utricularia ancestor. This ancestral characteristic still occurs in some species from the Bivalvaria subgenus. An embryo sac, which grows out beyond the limit of the integument and has contact with nutritive tissue, appeared independently in different Utricularia lineages and as a consequence of this, the egg apparatus changes position from apical to lateral
Potential for chromium (VI) bioremediation by the aquatic carnivorous plant Utricularia gibba L. (Lentibulariaceae)
Products of Culture of Islamic Countries from the Point of View of their Impact and Infleunce: The Case Study of the Specificities of Cultural Transfer
This diploma thesis will focus on music, film, literature and visual arts of Islamic coun-tries, as a material that leaves the original cultural and religious context and is being "sent" to be received in the context of the stabilised Western culture. Guided by her own judgment, the author of this diploma thesis shall select the most important and inte-resting artists who were born or are still living in one of the Islamic countries. And she will further interpret their work in terms of their influence and impact on the Western culture. As to the methodological approach, this diploma thesis is based on the concept of the cultural transfer, as it has been examined and defined in cultural studies in recent decades
Prague restaurant and pub names from an onomastic point of view
This bachelor thesis deals with the topic of chrematonymy. It contains a detailed list of Prague's restaurants and, using academic literature, provides an analysis of the individu-al semantic groups together with their motivations. The aim of the present thesis is to provide an overview of restaurant names in the Czech capital as well as to contribute to the overall knowledge of the local chrematonymy
Extracellular enzyme activities in benthic cyanobacterial mats: comparison between nutrient enriched and control sites in marshes of northern Belize
Auxiliary selection in present-day Italian
This thesis is dedicated to researching the use and importance of auxiliary verbs in tempi composti (compound tenses) in Italian language and grammar. Some of these verbs show variability and in some instances they might prefer a different auxiliary verb than is the one commonly allocated to them. In the theoretical section of this thesis, compound tenses and auxiliary verbs are introduced. That is followed by the explanation of theories that were presented by authors Antonella Sorace and Delia Bently, including non-accusative hypothesis. The research section of this thesis was based on following the categories presented in the non-accusative hypothesis. Numerous various verbs were chosen and subsequently tested in CORIS and ItWac. Their occurrence and preferences towards the auxiliary verb(s) was compared and contrasted with the above mentioned thoeries
