In the dissertation evaluated frost influence to the change of physical–mechanical properties of the reinforced concrete slabs for earth dam slope protection. Established ice thermal expansion linear load acting the slabs and proposed more exact calculation of this load. Evaluated deterioration indices and defects influence to slabs state and durability.

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.

The problems of particulate matter air pollution were analyzed, statistical data about particulate matter pollution in the world and in Lithuania were presented, necessity of particulate matter concentration assessment in the air of Žirmūnai and Žvėrynas districts of Vilnius were described, the main aims and tasks of work were described in the final master work. The data of Lithuanian air quality stations were analyzed too, and it was assessed that Vilnius is one of the most particulate matter polluted Lithuanian cities. The biggest concentrations of this pollutant during analyzed period were fixed in the Žirmūnai and Žvėrynas air quality stations. The methodology of investigation of particulate matter concentration in the air of Žirmūnai and Žvėrynas districts was described; places of measurement points, operation of a real time monitor „Microdust pro“ were characterized and the results of recording were presented, too. The model of particulate matter carry in Žvėrynas district with the help of „Phoenics“ modelling programme was made. The data of investigation (results of recording particulate matter concentration) and calculated results were compared, conclusions and suggestions given. The work has 6 chapters: introduction, the ambient air pollution with particulate matter; investigation of particulate matter concentration in the air of Vilnius districts, mathematical modelling of particulate matter concentration in the air of Žvėrynas district, general conclusions and...

This research deals with equivalent dose rate (EDR) in the ground level air caused by gamma radiation. Weighting factor for gamma radiation is equal one, so EDR in the ground air is identical absorbed ionic radiation dose. Highways A6 Kaunas-Zarasai and A11 Panevėžys-Šiauliai-Palanga were investigated. In this research the main parameters determining the level of equivalent dose rate in the ground air by the Lithuanian highways have been defined and analyzed. The objective of this research is to measure EDR in the ground air by the Lithuanian highways and compare to adequate average regional and with reference to modulation values evaluate variation reasons. In the expeditions EDR in the ground air was measured in winter and in summer. Samples of soil and asphalt were examined with gamma spectrometer and analyze presented. There was determined the dependence of EDR in the ground air from soil composition, floral or snow cover and distance to the asphalt cover. Cosmic radiation impact on EDR formation is equal to all locations. Natural origin radionuclides in soil gamma radiation have the main influence to EDR formation in the ground air. Modeling program VISIPLAN was used to define impact of radionuclides radiation in asphalt cover to EDR formation in the roadside zone. Modeling program InterRAS was used to define EDR in the ground air formation from gamma radiation of radionuclide in soil.

In the Master’s Thesis “Pre-investigation of Stormwater Quality at Metals Scrap Processing Plant” the literature review of 136 sources was performed with the focus on storm water pollution, physical and chemical properties of specific pollutants, origins of the pollution and pathways of the pollutants transport to the environment. Types of industrial storm water samples and sampling methodologies are described as well. Raprinfall data calculation are performed for the design of industrial storm water collection and treatment systems. The comprehensive analyses of storm water treatment are done. The experimental part of the work was carried out at the metal scrap processing industry with paved and unpaved aeries of the surfaces. During the research the industrial storm water screening characterisation was done at different locations of the whole territory. The treatment technology, including the sedimentation tank, retention tank and filtration trench was selected and calculated for the treatment of storm water of the investigated industry. The generalized conclusions and results of the work can be useful for state institutions, research institutions and the enterprises engaged in storm water management.

Žemė visais laikais buvo vertinama kaip visuotinė vertybė, kurios pagrindinė socialinė funkcija – tarnauti tautos gerovei. Bet kokia fizinė veikla keičia natūralią žemės būklę ir funkcijas, todėl atsižvelgiant į visuomeninių santykių, valstybės ekonomikos dinamikos ir raidos procesus, ypač svarbu, kad žemė būtų racionaliai ir efektyviai naudojama. Tai pagrindžia objektyviai nepaneigiamą pareigą valstybei nuosavybės į žemę, taip pat žemės valdymo ir naudojimo santykius reguliuoti taip, kad būtų suderinti visų žemės teisinių santykių subjektų interesai ir užtikrinta pagrindinė žemės funkcija. Žemės naudojimo valstybine kontrole būtent ir siekiama užtikrinti, kad valdant ir naudojant žemę, būtų laikomasi Lietuvos Respublikos žemės įstatymo bei kitų įstatymų, susijusių su žemės naudojimo priežiūra, taip pat apsaugoti valstybinės žemės nuosavybės teises. Žemės naudojimo valstybinė kontrolė - įstatymais ir kitais teisės aktais reglamentuotas žemės savininkų ir naudotojų veiklos priežiūros priemonių įgyvendinimo procesas, kuriuo siekiama užtikrinti tinkamą žemės ir gamtos išteklių naudojimą bei jų teisinę apsaugą, taip pat nustatyti nukrypimus nuo nustatytų reikalavimų ir užfiksuoti teisės aktų pažeidimus, bei pagal kompetenciją imtis įstatymų numatytų priemonių pažeidėjams nubausti. Už žemės naudojimo valstybinės kontrolės vykdymą atsakinga Nacionalinė žemės tarnyba prie Žemės ūkio ministerijos, tiesiogiai kontrolę vykdo teritoriniai žemėtvarkos skyriai. Baigiamajame darbe...

Any physical activity has impact on the natural state and functions of land, that is why the rational and effective use of land is so important. Public land use control has to ensure that the land administrators and land users respect and comply the laws regulating the land use and to protect the stateland ownership. Public land use control is the process of land administrators and land users activity supervision, which is regulated by laws, which is intended to ensure proper land and natural resources usage and legal protection, also identify deviation from the requirements and fixate violations, and under jurisdiction take legal actions to punish offenders. The Nacional Land Service under the Ministry of Agriculture of the Republic of Lithuania and territorial Land divisions are responsable for the public land use control.
