1,4-dihidropiridīna AV-153-Na mijiedarbības ar DNS molekulu izvērtējums šūnas ietvaros
2016
AV-153-Na ir 1,4-DHP analogs ar antimutagēnām un DNS pasargājošām īpašībām, kas spēj mijiedarboties ar DNS molekulu caur interkalāciju. Maģistra darba mērķis bija izvērtēt AV-153-Na spēju iekļūt šūnā un vizualizēt tā iespējamo mijiedarbību ar DNS molekulu. Rezultāti parādīja, ka AV-153-Na spēj nokļūt šūnā. AV-153-Na flluorescence tika vizualizēta gan dzīvās, gan fiksētās šūnās. Fluorescence tika konstatēta gan šūnu citoplazmā, gan šūnu kodolos. Pētāmā 1,4-DHP mijiedarbība ar DNS halo netika vizualizēta, tomēr pēc apstrādes ar koncentrētu sāļu šķīdumu fluorecence saglabājas tikai šūnu kodolu apvalku rajonā. Apkopojot iegūtos rezultātus un jau publicētos datus secinām, ka AV-153-Na mijiedarbo…

Views on Religious Freedom among Young People in Belarus and Norway: Similarities and Contrasts
2019
The study of religious freedom has not received sufficient empirical attention from sociologists of religion, despite significant theoretical discussion of the governance of religious freedom. This article suggests empirical findings about the views on religious freedom in Belarus and Norway from the international research project &ldquo

Composite analysis of the tropopause inversion layer in extratropical baroclinic waves
2018
Abstract. The variability and similarities in the evolution of the tropopause inversion (TIL) layer during cyclongenesis in the North Atlantic storm track are investigated using operational meteorological analysis data (Integrated Forecast System from the European Centre for Medium-Range Weather Forecasts). For this a total amount of 130 cyclones have been analysed which evolved during the months August through October between 2010–2014 over the North Atlantic. Their paths of migration along with associated flow features in the upper troposphere/lower stratosphere (UTLS) have been tracked using the mean sea level pressure. Subsets of the 130 cyclones have been used for composite analysis us…
Lignin oxidation products in soil, dripwater and speleothems from four different sites in New Zealand
2020
Lignin oxidation products (LOPs) are widely used as vegetation proxies in climate archives, such as sediment and peat cores. The total LOP concentration, Σ8, provides information on the abundance of vegetation, while the ratios C/V and S/V of the different LOP groups also provide information on the type of vegetation. Recently, LOP analysis has been successfully applied to speleothem archives. However, there are many open questions concerning the transport and microbial degradation of LOPs on their way from the soil into the cave system. These processes could potentially alter the original source-dependent LOP signals, in particular the C/V and S/V ratios, and thus complicate their interpre…
Quantification of lignin oxidation products as vegetation biomarkers in speleothems and cave drip water
2018
Here we present a sensitive method to analyze lignin oxidation products (LOPs) in speleothems and cave drip water to provide a new tool for paleo-vegetation reconstruction. Speleothems are valuable climate archives. However, compared to other terrestrial climate archives, such as lake sediments, speleothems contain very little organic matter. Therefore, very few studies on organic biomarkers in speleothems are available. Our new sensitive method allows us to use LOPs as vegetation biomarkers in speleothems. Our method consists of acid digestion of the speleothem sample followed by solid-phase extraction (SPE) of the organic matter. The extracted polymeric lignin is degraded in a microwave-a…
Characterisation of NO production and consumption: new insights by an improved laboratory dynamic chamber technique
2014
Biogenic NOx emissions from natural and anthropogenically influenced soils are currently estimated to amount to 9 Tg a−1, hence a significant fraction of global NOx emissions (45 Tg a−1). During the last three decades, a large number of field measurements have been performed to quantify biogenic NO emissions. To study biogenic NO emissions as a function of soil moisture, soil temperature, and soil nutrients, several laboratory approaches have been developed to estimate local/regional NO emissions by suitable upscaling. This study presents an improved and automated laboratory dynamic chamber system (consisting of six individual soil chambers) for investigation and quantification of all quant…
Applicability and consequences of the integration of alternative models for CO2 transfer velocity into a process-based lake model
2019
Freshwater lakes are important in carbon cycling, especially in the boreal zone where many lakes are supersaturated with the greenhouse gas carbon dioxide (CO2) and emit it to the atmosphere, thus ventilating carbon originally fixed by the terrestrial system. The exchange of CO2 between water and the atmosphere is commonly estimated using simple wind-based parameterizations or models of gas transfer velocity (k). More complex surface renewal models, however, have been shown to yield more correct estimates of k in comparison with direct CO2 flux measurements. We incorporated four gas exchange models with different complexity into a vertical process-based physico-biochemical lake model, MyLak…
