2017
Bakalaura darba tēma ir “Nepilna laika nodarbinātība Latvijā: studentu perspektīva”. Eiropas Savienības dalībvalstīs liela nozīme tiek piešėirta jauniešu bezdarba samazināšanai. Lai arī nepilna laika nodarbinātība Latvijā ir maz izplatīta, tā ir pieprasīta studējošu jauniešu vidū. Pētījuma mērėis ir noskaidrot studējošu jauniešu pieĦemtās prakses un to vērtējumu, apvienojot pilna laika studijas ar nepilna laika nodarbinātību Latvijā. Pētījuma rezultāti tiek skatīti darba, izglītības un citu dzīves jomu saskaĦošanas kontekstā. Bakalaura darbs satur 44 lappuses, 1 pielikumu, tā sagatavošanā izmantoti 28 literatūras un informācijas avoti.
Nepilngadīgo un pilngadīgo personu komunikācijas draudi un sekas iepazīšanās lietotnē "Tinder"
2021
Bakalaura darba tēma ir “Nepilngadīgo un pilngadīgo personu komunikācijas draudi un sekas iepazīšanās lietotnē “Tinder””. Darba mērķis ir izpētīt nepilngadīgo un pilngadīgo personu komunikācijas iespējamos draudus un sekas iepazīšanās lietotnē "Tinder". Bakalaura darba teorētiskā bāze pamatā balstās uz ārzemju pētījumiem par un ap aplikāciju “Tinder”: par pētījumiem, kuros analizēta “Tinder” un līdzīgu aplikāciju drošība un preventīvie drošības pasākumi situācijās, kad kāda no pusēm – pilngadīgais vai nepilngadīgais, lietojot sociālos tīklus iepazīšanās nolūkā, norāda nepareizu vecumu vai rada kādus citus draudus, kuru rezultātā var draudēt kriminālatbildība. Pētījumā tika veikta konstatē…
Heparin induces an accumulation of atherogenic lipoproteins during hemodialysis in normolipidemic end-stage renal disease patients
2014
Dyslipidemias may account for the excess of cardiovascular mortality in end-stage renal disease (ESRD). Lipoprotein studies in ESRD patients are usually relative to prehemodialysis samples even if significative changes may occur after dialysis. In this study, we aimed to investigate the effects of ESRD on triglyceride-rich lipoproteins (TRL) subpopulations distribution and acute change following hemodialytic procedures, including the relative contribution of heparin administration. We selected a group of normolipidemic male middle-aged ESRD patients free of any concomitant disease affecting lipoprotein remnant metabolism compared with controls. We separated TRL subfractions according to den…
Marks and Epigraphs on Iberian Amphorae. II
2015
Se presenta la segunda parte del repertorio de marcas y epígrafes sobre ánforas ibéricas, con la intención de completar un fenómeno heredero del mundo púnico. Se pretende ir acotando el/los posible/s significado/s de tales marcas, su distribución territorial y su marco cronológico. Las marcas incisas son, en esta ocasión, más numerosas que las impresas y se ha detectado una nueva técnica postcocción (con pintura y carbón) restringida al noreste peninsular. This paper is the second part of the repertoire of marks and epigraphs on Iberian amphorae. The goal is to complete this work, which is related to the Punic world, and know the possible meanings of such marks, their geographical distribut…
Matrix Metalloproteases in Arterial Hypertension and their Trend after Antihypertensive Treatment
2017
<b><i>Background/Aims</i></b><b><i>:</i></b> Arterial hypertension is characterized by vascular remodelling, atherosclerosis and cardiovascular complications. Matrix metalloproteases (MPPs) are endopeptidases produced by all the cells present in the vascular wall and are involved in the regulation of the extracellular matrix protein turnover. MMPs contribute to blood vessel formation, remodelling, angiogenesis; whereas an altered expression or activity of MMPs or their tissue inhibitors (TIMPs) results correlated with the development and progression of cardiovascular complications. <b><i>Methods:</i></b> We examined the…
Microphysical and radiative characterization of a subvisible midlevel Arctic ice cluod by airborne observations - a case study
2009
During the Arctic Study of Tropospheric Aerosol, Clouds and Radiation (ASTAR) campaign, which was conducted in March and April 2007, an optically thin ice cloud was observed south of Svalbard at around 3 km altitude. The microphysical and radiative properties of this particular subvisible midlevel cloud were investigated with complementary remote sensing and in situ instruments. Collocated airborne lidar remote sensing and spectral solar radiation measurements were performed at a flight altitude of 2300 m below the cloud base. Under almost stationary atmospheric conditions, the same subvisible midlevel cloud was probed with various in situ sensors roughly 30 min later. <br><br> …
Coastal zone water quality: Calibration of a water-turbidity equation for MODIS data
2013
AbstractA nephelometric turbidity algorithm has been specifically calibrated for coastal waters in Sicily. To this purpose, intensive field campaigns were performed in July, August and September 2008. Measurements were collected in situ in three different gulfs. Statistical analysis suggests that field data should be spatially grouped but temporally separated; hence, new calibration parameters have been proposed.Turbidity retrieved by applying the algorithm using literature coefficients and the ones calibrated in situ are shown and compared. The comparison demonstrated that a specific calibration was necessary for quantitatively monitoring turbidity in Sicilian gulfs.
The evolution of microphysical and optical properties of an A380 contrail in the vortex phase
2012
A contrail from a large-body A380 aircraft at cruise in the humid upper troposphere has been probed with in-situ instruments onboard the DLR research aircraft Falcon. The contrail was sampled during 700 s measurement time at contrail ages of about 1–4 min. The contrail was in the vortex regime during which the primary wake vortices were sinking 270 m below the A380 flight level while the secondary wake remained above. Contrail properties were sampled separately in the primary wake at 90 and 115 s contrail age and nearly continously in the secondary wake at contrail ages from 70 s to 220 s. The scattering phase functions of the contrail particles were measured with a polar nephelometer. The …
Determination and analysis of in situ spectral aerosol optical properties by a multi-instrumental approach
2014
Continuous in situ measurements of aerosol optical properties were conducted from 29 June to 29 July 2012 in Granada (Spain) with a seven-wavelength Aethalometer, a Multi-Angle Absorption Photometer, and a three-wavelength integrating nephelometer. The aim of this work is to describe a methodology to obtain the absorption coefficients (babs) for the different Aethalometer wavelengths. In this way, data have been compensated using algorithms which best estimate the compensation factors needed. Two empirical factors are used to infer the absorption coefficients from the Aethalometer measurements: C – the parameter describing the enhancement of absorption by particles in the filter matrix due …
Sources of discrepancy between aerosol optical depth obtained from AERONET and in-situ aircraft profiles
2012
Abstract. Aerosol optical properties were measured by NOAA's Airborne Aerosol Observatory over Bondville, Illinois, during more than two years using a light aircraft. Measured properties included total light scattering, backscattering, and absorption, while calculated parameters included aerosol optical depth (AOD), Ångström exponent, single-scattering albedo, hemispheric backscatter fraction, asymmetry parameter, and submicrometer mode fraction of scattering. The in-situ aircraft measurements are compared here with AERONET measurements and retrievals of the aerosol optical properties at the same location, although it is difficult to verify the AERONET retrieval algorithm at a site that is …
