In master thesis researches to appreciate the agrarian strain to basin of river Tatula in the North karst region area of Lithuania. Object of the work: The basin of river Tatula, which is in the North karst region area of Lithuania. Aim of work: 1. gather up the water samples of river Tatula in autumn and spring; 2. to do ourselves the water quality researches of river Tatula; 3. to collect farmers in basin of river Tatula by questionnaires method; 4. to sum up the results and to dimension pollution’s sizes and sources; Methods of the work: The river samples were taken in 2003, 2004 autumn and 2004, 2005 spring. Water samples were taken up to the river, middle of the river and down to the river. Then water samples were transported to a laboratory, where would be setted: pH of the water, permanganate oxidation, BDS, ammonium azote concentration, phosphate phosphorus. Also were collected farmers who were farming in basin of Tatula by questionnaires method. Work out results of the waters quality shows that agrarian work effect partially influence pollution basin of river Tatula. When were done water‘s researches of river Tatula were setted ammonium azote concentration exceeded DLK and river water's quality was bad, compare with the other assay parameters water‘s quality is unbroken DLK. Keywords: The North karst region area of Lithuania, the basin of river, the agrarian strain, BDS7, pH, ammonium azote.

<div><div><div><p>The radionuclide 10Be is produced in the atmosphere and is delivered to Earth’s surface in meteoric rain and aerosols. The stable nuclide 9Be is present in trace concentrations within rocks in Earth’s crust and is released via chemical weathering. Together, these two isotopes have been employed to study a wide range of Earth processes. Here I explore new terrestrial archives of Be isotopes: cave speleothems and terrestrial Mn-oxides. Until this point, these archives have barely been studied. Only one published dataset of Be isotopes in cave speleothems exists (Lundblad, 2006), and to my knowledge, terrestrial manganese oxides are yet to be explored. However, since speleothems and Mn-oxides precipitate from groundwater, they have the potential to encode temporal variations in the 10Be/9Be ratio of water and colloids in the vadose zone.</p><p>I develop a framework for using the 10Be/9Be ratio in the dissolved phase and/or secondary weathering products as a metric of chemical weathering rate. I am motivated by several over-arching questions:</p><ol><li><p>1) Which factor, or factors, is/are dominant in controlling Be isotopes in speleothems and terrestrial Mn-oxides?</p></li><li><p>2) Can Be isotopes in speleothems be used as a metric of weathering rate over time, particularly across glacial/interglacial cycles?</p></li><li><p>3) Can Be isotopes be used to date the formation of terrestrial Mn-oxides?</p></li></ol><p>I measure Be-isotope concentrations in speleothems from Soreq Cave, Israel. By applying an equation that I derive in this thesis, I use the temporal variation in the speleothem10Be/9Be ratio to calculate chemical weathering rates over the last 168 ka. Chemical weathering varies with independent proxies for temperature. The weathering-temperature relationship can be fit to an Arrhenius relationship, and the calculated activation energy (Ea) matches other field-based estimates for feldspar, an abundant mineral in the soil above the cave. In the Appendices I present additional results of Be-isotope measurements in a flowstone from Buffalo Cave in South Africa, as well as Mn-oxides from the Appalachians.</p></div></div></div>

This thesis analysis the funding possibilities from structural funds for the development of water management in villages as well as different legal acts and international covenants whose regulations corresponds the project The Development of the System for Collecting Waste Water in Kirdoniai Village of Birzai District. It also analysis whether this project corresponds the SPD, its impact on the environment and the EU horizontal politics. In this thesis a lot of data are used, which were processed using ordinary statistical methods along with cost-benefit analysis recommended by the European Commission and the method proposed by the Environmental Project Management Agency used for financial and economic analysis. For data processing DAM and the MS Excel programmes were used. During the research the characteristics of Kirdoniai Village territory in Birzai district were analysed as well as the existing situation of drink water supply and the collection of waste water. It was also examined who could benefit from this project, what problems could this project solve. The formulation of the investment project was carried out. The research results were used by the Municipality Administration of Birzai district, which submitted the application according to the 1st priority “The development of social and economic infrastructure”, the 1.3 measure “The improvement of environment’s quality and the prevention of environmental damage” of activities’ group “The supply of drink water and...
