Climate change impact assessment on various components of the hydrological regime of the Mal e River basin
Soňa Něme ková, Romana Slámová, Václav ípek
Journal of Hydrology and Hydromechanics , 2011, DOI: 10.2478/v10098-011-0011-y
Abstract: Climate change impacts on water cycle at regional scale have been recently very investigated and discussed issue. This study focuses on changes of not only total runoff but also others water balance components: soil water content and evapotranspiration, in a monthly step. The climate change was described using outputs of two different global circulations models, ECHAM and HadCM based on two divergent scenarios (optimistic B1 and pessimistic A2) according to the IPCC. The simulation of water cycle was processed in the mesoscale Malse basin (437 km2) in southern Bohemia using distributed physically based hydrological model SWIM. The outputs for the time horizon 2050 were assessed in comparison with mean values from the representative period 1987-1998. The study indicates vulnerability against predicted changes of both temperature and precipitation patterns referred to the selected scenarios. A decrease of total runoff was expected; however, hydrological balance will be different particularly in the monthly pattern within a year. The aim of this article is to describe the impact on various hydrological balance components.
To an Axiomatic Model of Rate of Growth  [PDF]
Václav Studeny, Ivan Mezník
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.49179
Abstract:

In the paper an axiomatic approach to express rates of growth is presented. The formula is given of rate of growth at a point as the limit case of rate of growth on an interval and the inverse formula is derived to compute present and future value of capital for an integrable rate of growth. Incidentally some inconsistencies in currently used formulas are pointed out.

PRESTA: associating promoter sequences with information on gene expression
Václav Mach
Genome Biology , 2002, DOI: 10.1186/gb-2002-3-9-research0050
Abstract: The PRESTA algorithm examines the putative GenBank/EMBL promoters and automatically removes most of the poorly annotated entries. The remaining records are connected to expressed sequence tags (ESTs) through a high-stringency BLAST search. The frequency and source of recovered ESTs provide an estimate of the activity and expression pattern of the promoter, and the ESTs' 5' ends assist in transcription start-site verification. The PRESTA database provides easy access to non-redundant upstream regulatory regions recently extracted by the PRESTA algorithm. The current size of this resource is 552 human and 241 mouse promoters. Surprisingly, no overlap between the PRESTA database and the Eukaryotic Promoter Database (EPD) was detected by sequence comparison.The PRESTA algorithm demonstrates the principle of promoter verification by mapping EST 5' ends. The publicly available PRESTA database collects hundreds of characterized and partially verified promoter sequences and is complementary to other promoter databases.Construction of large sets of well-characterized promoter sequences is driven by a general expectation that detailed comparative studies exploiting large groups of promoters will eventually lead to an understanding of promoter architecture. The two prominent currently available resources of upstream promoter sequences are the Transcription Regulatory Regions Database (TRRD) [1] and the Eukaryotic Promoter Database (EPD) [2]. They rely on published data and frequently neglect experimentally characterized but otherwise unpublished promoters submitted to GenBank [3] and EMBL [4] libraries. This suggests the idea of exploiting GenBank and EMBL as an alternative source of annotated upstream regulatory sequences. Unfortunately, any organism-wide GenBank/EMBL query intended to retrieve promoter sequences will recover records containing data of very variable quality. Removal of inadequate or poorly annotated entries requires considerable manual effort and can be great
A note on integral vortex strength
Václav Kolá
Journal of Hydrology and Hydromechanics , 2010, DOI: 10.2478/v10098-010-0003-3
Abstract: Controversial aspects of the conventional and widely used concept of the integral vortex strength are briefly discussed. The strength of a vortex is usually calculated as the circulation along the vortex boundary, or equivalently due to Green's theorem, as the surface integral of vorticity over the planar vortex cross section. However, the local effect of an arbitrary "superimposed shear" is fully absorbed by vorticity what makes the circulation a shear-biased vortex characteristic. The present paper shows that different vortex-strength models can be derived on the basis of different local vortex intensities proposed in the literature. The outcome of these models naturally differs, even for an ideally axisymmetric vortex. Three different vortex-strength models are compared and discussed by examining the unsteady Taylor vortex.

Vyvoj a proměny stranického systému na Faerskych ostrovech
Václav Brachtl
St?edoevropské Politické Studie , 2010,
Abstract: Party System Development in the Faroe Islands. The article deals with the creation of and changes in the party system of the Faroe Islands. Sartori’s party system typology is used. Attention is also paid to the cleavages shaping the Faroese party system. The story of Faroese party politics starts at the beginning of the 20th century when the Unionist and Self-Government parties were founded. The system was influenced mainly by Faroese-Danish relations and by economic crises in the 1920s and 1990s.
Field research as village community’s cultural awareness identification tool
Michali?ka Václav
Glasnik Etnografskog Instituta SANU , 2010, DOI: 10.2298/gei1002088m
Abstract: The conference paper will deal with possibilities of specific assets and outcomes of field research in a village as an enclosed housing, social and cultural space. It will focus on the role of field research as a tool of identification of cultural awareness of a village. The relationship between research, its outcomes and subsequent reaction of dwellers will be defined as well as question of impact of such research on local identity. The case study will show particular village with developed traditional craft production (already extinct). Apart from realizing (or re-building) local identity, new possibilities of reconstruction of the extinct technology or even particular aspects of historic environment open up here.
Utilization of residual reserves of coal strata outcrops by open-pit mining with a subsequent disposal of industrial waste
Kryl Václav
Acta Montanistica Slovaca , 1998,
Abstract: In the paper the author deals with the possibilities of open-pit mining of residual reserves of coal seam outcrops. Following the coal extraction, certified regional industrial waste can be disposed in the mined-out area, thus reducing the environmental burden of the region.
