Import 22/07/2015Diplomová práce je zaměřena na zpracování návrhu strategie pro podnik Rajnošek s.r.o. Podnikatelská činnost tohoto podniku se týká autodopravy, zemních a jeřábnických prací v Jihomoravském kraji. V teoretické části jsou vymezeny základní pojmy, které nezbytně souvisí s tematickým celkem této práce. Také jsou zde popsány jednotlivé metody, které byly aplikovány na zkoumanou společnost při analýze celkového stavu firmy. V praktické části je nejprve detailně představen zvolený podnik a následně je provedeno několik typů analýzy, po jejichž vyhodnocení došlo k návrhu jednotlivých doporučení, jež by měla vést k žádoucím změnám a především k formulaci nejvhodnější firemní strategie.The thesis is focused on the development of the strategy proposal for the company Rajnošek s.r.o. The business activity of the company covers transport, earthworks and crane work in South-Moravian region. The theoretical part of the basic concepts that are necessarily associated with thematic units of this work . Also described are various methods that have been applied to the study of the organization in analyzing the overall condition of the company. In the practical part is the first detailed presentation of the selected company and subsequently made several types of analysis, evaluation, after which there was a draft of the recommendations which should lead to the desired changes and especially to the most appropriate formulation of corporate strategy.152 - Katedra podnikohospodářskávelmi dobř

Ocean acidification impacts spine integrity but not regenerative capacity of spines and tube feet in adult sea urchins

Increasing atmospheric carbon dioxide (CO2) has resulted in a change in seawater chemistry and lowering of pH, referred to as ocean acidification. Understanding how different organisms and processes respond to ocean acidification is vital to predict how marine ecosystems will be altered under future scenarios of continued environmental change. Regenerative processes involving biomineralization in marine calcifiers such as sea urchins are predicted to be especially vulnerable. In this study, the effect of ocean acidification on regeneration of external appendages (spines and tube feet) was investigated in the sea urchin Lytechinus variegatus exposed to ambient (546 µatm), intermediate (1027 µatm) and high (1841 µatm) partial pressure of CO2 (pCO2) for eight weeks. The rate of regeneration was maintained in spines and tube feet throughout two periods of amputation and regrowth under conditions of elevated pCO2. Increased expression of several biomineralization-related genes indicated molecular compensatory mechanisms; however, the structural integrity of both regenerating and homeostatic spines was compromised in high pCO2 conditions. Indicators of physiological fitness (righting response, growth rate, coelomocyte concentration and composition) were not affected by increasing pCO2, but compromised spine integrity is likely to have negative consequences for defence capabilities and therefore survival of these ecologically and economically important organisms
