Vliv druhového složení květnatých pásů ve městech na skladbu opylovačů.
FIŠEROVÁ, Alena
This masters thesis studies the influence of species diversity of bloomig flowers in the flower strips on the composition of pollinators community, which is wisiting the flower strips. The flowers are blooming plentiful during the whole season and therefore they are providing resources for the functional groups of pollinators. Therefore these flower strips are helping to increase the biodiversity in cities.

Wastewater Treatment Using House Sewage Treatment Plants {--} Hygienic Aspects and Usage in the Czech Republic
FIŠEROVÁ, Alena
Constructed wetlands (CWs) originate from natural wetlands and are used for waste water treatment as an alternative to conventional treatment. This thesis was aimed at providing a literary summary of the types of house sewage water treatment plants and constructed wetlands used in the CR and abroad, of their hygienic aspects, functionality, treatment efficiency, expensiveness and the possibilities of their use in the conditions of the CR and their advantages and disadvantages. It also deals with a proposal of a suitable type of house CW for the conditions of the CR and a list of the necessary steps in construction of a house CW. Quite similar systems are being used for house sewage treatment in the Czech Republic and abroad {--} mostly septic tanks, ground mounds, constructed wetlands, active treatment plants and biodiscs. Alternative water treatment methods are generally not suitable for buildings having (now or in the future) the possibility of connection to municipal sewerage systems. They are on the other hand suitable for buildings not connected to sewerage systems or for seasonal objects, remote places and holiday houses with seasonal waste water production. A system with horizontal subsurface flow is mostly used as a CW in the Czech Republic. This CW type ensures sufficient removal of organic contamination and insoluble substances, but the efficiency of nitrogen and phosphorus removal is relatively low. However it is fully sufficient in the instance of low PE numbers, as the loading rate is usually low and the concentration of contaminants in the output water meets the prescribed limits. Foreign researches show that hybrid systems combining horizontal flow with vertical flow and with recirculation are more suitable for improving efficiency of nitrogen removal. Systems with vertical flow and intermittent waste water dosage showing particularly good results in ammoniac removal are also suitable for nitrogen removal. Special materials with higher iron, aluminium or calcium content are most suitable as filling of a constructed wetland or as additional filters or for improvement of phosphorus removal from waste water as they are able to reach efficiency of up to 90 %. In my thesis I came to a conclusion that a CW with horizontal subsurface flow is the most suitable type of house constructed wetland treatment for the conditions in the CR, mainly because it is the most frequently used and thus best proven CW type with sufficient efficiency of treatment for the substances required by standards.

EFFICIENCY OF ENTEROCOCAL AND THERMOTOLERANT COLIFORMING BACTERIA REMOVAL IN CONSTRUCTED WETLAND USED FOR WASTEWATER TREATMENT
FIŠEROVÁ, Alena
Constructed wetlands (CWs) have their origin in natural wetlands and they are used for a wastewater treatment as an alternative of the classical technology. In the Czech Republic are used only CW with subsurface horizontal flow with emergent macrophytes for the wastewater treatment. The efficiency of the enterococal and thermotolerant coliforming bacteria removal was followed in the CW in Slavošovice. In the regular intervals (2-6 weeks) from May 2006 to March 2007, wastewater was sampled at the inflow, after the mechanical pretreatment and at the outflow. The number of the enterococal and thermotolerant coliforming bacteria was calculated in the samples and the efficiency of the bacterial removal was evaluated during winter and summer seasons.

Neobnovitelné přírodní zdroje
Vařeková, Veronika ; Dvořák, Antonín (advisor) ; Fišerová, Alena (referee)
Kromě souvisejících, ale vedlejších témat jsou stěžejním tématem této práce neobnovitelné přírodní zdroje. A sice jejich zásoba ve světě a zabezpečení se zaměřením na Českou republiku, která se nás pochopitelně dotýká nejvíce. Práce také poukazuje na aktuální otázky a problémy, které dnes svět, v souvislosti s títo tématem, řeší.

Ecolabelling

Bakalárska práca s názvom "Označovanie ekologicky šetrných výrobkov" je venovaná označovaniu ekologicky šetrných výrobkov so zameraním na ekoznačenie v Českej republike, resp. na Program označovania výrobkov ochrannou známkou "Ekologicky šetrný výrobok".Zaoberá sa jeho pokrokmi,ale i problémami,ktorým musí čeliť.Poukazuje i na miesto ekolabelingu v širšom systéme dobrovoľných environmentálnych značení(predovšetkým na základe delenia Medzinárodnej organizácie pre štandardizáciu).V súvislosti s Európskou úniou ponúka práca informácie o ekoznačke EU-"The Flower".
