On the Dependence of Cirrus Parametrizations on the Cloud Origin
2019
<p>Particle size distributions (PSDs) for cirrus clouds are important for both climate models as well as many remote sensing retrieval methods. Therefore, PSD parametrizations are required. This study presents parametrizations of Arctic cirrus PSDs. The dataset used for this purpose originates from balloon-borne measurements carried out during winter above Kiruna (Sweden), i.e. north of the Arctic circle. The observations are sorted into two types of cirrus cloud origin, either in-situ or liquid. The cloud origin describes the formation pathway of the ice particles. At temperatures below −38 °C, ice particles form in-situ from solution or ice nuclea…
Antiviral and antioxidant properties of active alginate edible films containing phenolic extracts
2018
In this work, novel active edible films having antiviral activity were developed through the solvent casting method. Emulsified edible films were prepared by adding lipids into alginate films in order to improve their water vapour permeability. In addition, two natural extracts rich in phenolic compounds, specifically a green tea extract (GTE) and a grape seed extract (GSE) were used as active agents. Interestingly, incorporating GTE or GSE within the biopolymer matrix, the films exhibited significant antiviral activity against murine norovirus (MNV) and hepatitis A virus (HAV) since ∼2 log reduction were recorded for the 0.75 g extract/g alginate in the film, being GTE more efficient than …
Effect of green tea extract on enteric viruses and its application as natural sanitizer
2017
In this work, the effect of green tea extract (GTE) was assessed against murine norovirus (MNV) and hepatitis A virus (HAV) at different temperatures, exposure times and pH conditions. Initially, GTE at 0.5 and 5 mg/ml were individually mixed with each virus at 5 log TCID50/ml and incubated 2 h at 37 °C at different pHs (from 5.5 to 8.5). GTE affected both viruses depending on pH with higher reductions observed in alkaline conditions. Secondly, different concentrations of GTE (0.5 and 5 mg/ml) were mixed with viral suspensions and incubated for 2 or 16 h at 4, 25 and 37 °C at pH 7.2. A concentration-, temperature- and exposure time-dependent response was showed by GTE in suspension tests, w…

Amatas upes hidroloģiskā režīma ilgtermiņa un sezonālās izmaiņas
2017
Darba mērķis ir izvērtēt Amatas upes hidroloģiskā režīma sezonālās un ilgtermiņa izmaiņas mainīga klimata apstākļos. Darbā raksturots Gaujas baseina upju hidroloģiskais režīms un to ietekmējošie faktori, aplūkoti hidroloģiskā režīma pētījumi Latvijā un Baltijā. Veikts Amatas upes baseina fizioģeogrāfiskais raksturojums. Analizēti rezultāti par Amatas upes hidroloģiskā režīma raksturojošo parametru (caurplūdums, temperatūra, ledus izveidošanās un uzlūšanas datumi, ledstāves ilgums) sezonālajām un ilgtermiņa izmaiņām un to savstarpējo korelāciju ar meteoroloģiskajiem parametriem (gaisa temperatūra un atmosfēras nokrišņi) laika periodā no 1921.-2015. gadam. Noteces režīms raksturots, analizējo…
Zu interkulturellen Begegnungen in der gymnasialen Oberstufe : Erfahrungen finnischer Schüler mit finnisch-deutschen Schulpartnerschaften
2011
Nykyinen käsitys vieraiden kielten opettamisesta Suomessa painottaa kielen lisäksi myös kohdekulttuurin tuntemusta. Kielen opetuksessa tulisi huomioida sen kulttuurinen konteksti. Tämän tutkimuksen tavoitteena oli kartoittaa suomalaisten lukiolaisten kokemuksia ulkomaisesta ystävyyskoulutoiminnasta. Erityisen kiinnostuksen kohteena olivat lukiolaisten motiivit osallistua projektiin, heidän näkemyksensä projektin suunnittelusta ja toteutuksesta, sekä heidän kokemuksensa projektin vaikutuksista kulttuurienväliseen oppimiseen ja kielitaitoon. Työn teoreettisessa osassa tarkastellaan kulttuurienvälistä kompetenssia kansainvälisyyskasvatuksen tavoitteena Suomen lukio-opetussuunnitelmassa ja sen …
Nosacījuma palīgteikumi Britu nacionālā korpusa tirdzniecības sadaļā
2015
Bakalaura darbā tiek pētīti nosacjuma palīgteikumi Britu Nacionālā Korpusa tirzdniecības sadaļā. Pastāv dažādu veidu nosacījuma palīgteikumi, un to lietošanas nolūks atšķiras. Tie tiek izmantoti dažādās jomās: gan ikdienas komunikācijā, gan biznesa, gan tirzdniecības jomās. Nosacījuma palīgteikumus angļu valodā izmanto, lai izteiktu vispārīgus faktus un īstus vai neīstus notikumus. Darba mērķis ir izpētīt nosacījuma palīgteikumus Britu Nacionālā Korpusa tirzdniecības sadaļā, lai noskaidrotu, kādu funkciju tie pilda teikumos. Pētījuma darba metode ir kvantitatīva un kvalitatīva uz korpusu balstīta nosacījuma palīgteikumu analīze, izmantojot konkordances metodi. Pētījuma rezultāti attēlo visb…
CUSHAW2-GPU: Empowering Faster Gapped Short-Read Alignment Using GPU Computing
2014
We present CUSHAW2-GPU to accelerate the CUSHAW2 algorithm using compute unified device architecture (CUDA)-enabled GPUs. Two critical GPU computing techniques, namely intertask hybrid CPU-GPU parallelism and tile-based Smith-Waterman map backtracking using CUDA, are investigated to facilitate fast alignments. By aligning both simulated and real reads to the human genome, our aligner yields comparable or better performance compared to BWA-SW, Bowtie2, and GEM. Furthermore, CUSHAW2-GPU with a Tesla K20c GPU achieves significant speedups over the multithreaded CUSHAW2, BWA-SW, Bowtie2, and GEM on the 12 cores of a high-end CPU for both single-end and paired-end alignment.
Reverse inheritance in statically typed object-oriented programming languages
2010
Reverse inheritance is a new class reuse mechanism, an experimental implementation of which we have built for Eiffel. It enables a more natural design approach, factorization of common features (members), insertion of classes into an existing hierarchy etc. Due to its reuse potential in Eiffel we consider exploring its capabilities in other industrial-strength programming languages like C++, Java and C#.
