(Vandens ūkio inžinerija, 2007)Straipsnyje pateiktas reguliuotų Pietryčių Lietuvos upelių, apaugusių sumedėjusia augalija, funkcionalumo (hidraulinio pralaidumo) modeliavimas ir galimybės planuoti reguliuotų upelių natūralizavimą. Sumedėjusios augalijos ... -
Anaerobic recycling of organic waste and recovery of biogas
(Ekologija, 2008)The authors analyse the quantitative and qualitative findings of research on biogas. Biogas was recovered by anaerobic biodegrading of various substrates: sewage treatment sludge, hen manure, and pig manure. The volume of ... -
Investigation of temperature dynamics in composted waste
(Ekologija, 2008)Waste management is a relevant issue for Lithuania. The municipal waste collection systems are not efficient, the equipment is worn out. The majority of waste that could be reused is disposed in the landfills. One of waste ... -
The impact of lime on water quality when draining clay soils
(Ekologija, 2008)A slightly decreasing trend of TP (r = 0.49) and PO4–P (r = 0.54) concentrations was determined in the stream where drainage water is discharged. As regards nitrogen concentrations, the differences in drainage treatments ... -
The safety design methodology of beams of hyperastatic bar structures
(Вiсник нацiонального унiверситету "Львiвська полiтехнiка". Теорiя i практика будiвництва, 2007)An assessment of structural and technological features in the design methodology of hyperstatic precast reinforced concrete and composite steel-concrete strucutres is discussed. Permanent and variable service, snow and ... -
Experimental and theoretical study of pollutant dispersion along a highway
(Geologija, 2007)A model of particle dispersion when there is a crosswind was created on the grounds of the Gaussian distribution of particles over a road. When the wind is absent, a cylindrical cut-shaped whirl of dust immediately changes ... -

Heterogeninių komponentų jungimas į sudėtinius komponentus: sprendimai ir jų realizavimas
(Informacinės technologijos : konferencijos pranešimų medžiaga, 2007)Komponentinės inžinerijos metodai turi būti praplėsti norint juos taikyti informacinėms sistemoms kurti. Darbe nagrinėjama heterogeninių komponentų jungimo į aukštesniojo lygmens sudėtinius komponentus problema. Pateikiamas ... -
On normal approximation of discounted and strongly mixing random variables
(Lietuvos matematikos rinkinys, 2007)We estimate the difference |Eh(Z_v)-Eh(N)|for bounded functions h: R->R satisfying the Lipschitz condition, where [...] with discount factor v such that 0<v<1. Here {X_n,n>=0} is a sequence of strongly mixing random variables ... -
Use of Poaceae f. species to decontaminate soil from heavy metals
(Ekologija, 2007)Soil contamination with heavy metals is a problem of worldwide concern and is still unsolved. Phytoremediation is a new and prospective technology that applies plants for cleaning lightly contaminated soils. Three kinds ... -
Spectral problem for the mean field Hamiltonian
(Lietuvos matematikos rinkinys, 2007)We consider the mean field Hamiltonian [...] is a finite set. Characteristic equations for eigenvalues and expressions for eigenfunctions of [...] are obtained. Using this result, the spectral representation of the solution ... -
Accumulation particularities of 90Sr and 137Cs radionuclides in different fish groups
(Ekologija, 2007)Radionuclide accumulation in settled and migratory fish caught in Lithuanian lakes and rivers was analysed. Migratory fish were found to accumulate radionuclides in muscles (53–63%) and bones (33–42%), mainly from food. ... -
Influence of biofilter’s temperature regimes on air cleaning
(Ekologija, 2007)Microorganisms cultivated in the biofilter in the course of air cleaning depend on ambient ecological factors that have impact on organism development, procreation, oxidation of pollutants etc. Among the major ecological ... -
Research into heavy metal concentrations in agricultural soils
(Ekologija, 2007)This paper describes soil pollution in a pig farm while fertilizing soil by organic fertilizers. The farm needs to get IPPC permit, so it is essential to determine pollution impact on the environment. The paper analyses ... -
