Priekšrocības un trūkumi vācu valodas kā svešvalodas nodarbībās tiešsaistē
2021
Mana bakalaura darba mērķis ir izzināt, cik efektīvas ir vācu valodas mācības tiešsaistē no studentu un skolnieku puses. Šim nolūkam tiek tuvāk pētīts, kādas ir galvenās un visbiežāk sastopamās problēmas tiešsaistes apmācībās. Šīs pētījums balstās uz studentu un skolnieku aptaujas rezultātiem, pasniedzēju komentāriem, kā arī tiešsaistes mācību stundās izmantotiem materiāliem. Pētījuma gaitā tika secināts, ka lielākajai daļai studentu un skolnieku online mācības rada būtiskas problēmas, piemēram, mācību process aizkavējas (ir lēnāks), mācību materiāla apguvē ir vērojamas nepilnības, skolēniem un studentiem ir grūti ilgstoši koncentrēties.
The HPC Certification Forum: Toward a Globally Acknowledged HPC Certification
2020
The goal of the HPC Certification Forum is to categorize, define, and examine competencies expected from proficient HPC practitioners. The community-led forum is working toward establishing a globally acknowledged HPC certification process, a process that engages with HPC centers to identify gaps in users’ knowledge, and with users to identify the skills required to perform their tasks. In this article, we introduce the forum and summarize the progress made over the last two years. The release of the first officially supported certificate is planned for the second half of 2020.
Histone Code and Higher-Order Chromatin Folding: A Hypothesis
2016
AbstractHistone modifications alone or in combination are thought to modulate chromatin structure and function; a concept termed histone code. By combining evidence from several studies, we investigated if the histone code can play a role in higher-order folding of chromatin. Firstly using genomic data, we analyzed associations between histone modifications at the nucleosome level. We could dissect the composition of individual nucleosomes into five predicted clusters of histone modifications. Secondly, by assembling the raw reads of histone modifications at various length scales, we noticed that the histone mark relationships that exist at nucleosome level tend to be maintained at the high…
Basaltic Rocks Analyzed by the Spirit Rover in Gusev Crater
2004
The Spirit landing site in Gusev Crater on Mars contains dark, fine-grained, vesicular rocks interpreted as lavas. Pancam and MiniâThermal Emission Spectrometer (Mini-TES) spectra suggest that all of these rocks are similar but have variable coatings and dust mantles. Magnified images of brushed and abraded rock surfaces show alteration rinds and veins. Rock interiors contain â¤25% megacrysts. Chemical analyses of rocks by the Alpha Particle X-ray Spectrometer are consistent with picritic basalts, containing normative olivine, pyroxenes, plagioclase, and accessory FeTi oxides. MoÌssbauer, Pancam, and Mini-TES spectra confirm the presence of olivine, magnetite, and probably pyroxene. The…
Love, joy and necessity - A phenomenological study of food and meals in adolescents and young adults with cancer receiving high-emetogenic chemothera…
2021
Abstract Purpose This study explored how the phenomenon of meals appeared in the interrelationship between adolescents and young adults (AYAs) receiving high-emetogenic chemotherapy, their next of kin and health professionals in the clinical setting. Method Data were collected by 140 h of participant observation conducted to gain insights into the nature of how meals appeared in the interrelationship between 12 AYAs (age 15–29 years), their next-of-kin and health professionals. The AYAs were patients with oncological and haematological diseases recruited from three university hospital departments. Data analysis was guided by van Manen's hermeneutic-phenomenological approach. Results The ess…
Review of the relationship between aggregates geology and Los Angeles and micro-Deval tests
2021
Rock aggregates constitute the enormous volume of inert construction material used around the globe. The petrologic description as igneous, sedimentary, and metamorphic types establishes the intrinsic formation pattern of the parent rock. The engineering properties of these rocks vary due to the differences in the transformation process (e.g. hydrothermal deposits) and weathering effect. The two most common mechanical tests used to investigate the performance of aggregates are the Los Angeles (LA) and micro-Deval (MD) tests. This study reviewed the geological parameters (including mineralogy, grain and crystal size, grain shape, and porosity) and the relationship to Los Angeles and micro-De…
Flavor Release from i-Carrageenan Matrix: A Quantitative Structure-Property Relationships Approach
2006
International audience; We carried out a QSPR (quantitative structure-property relationships) approach to evaluate the influence of the chemical structure of aqueous matrixes over the partition coefficient between the gas phase and the matrix. The determination of the partition coefficient of flavor ingredients was performed by headspace analysis at equilibrium for both saline solution and -carrageenan gel. Starting from an initial list of 90 descriptors, we selected 10 descriptors to perform equation generation by the GFA (genetic function approximation) method available in the Cerius2 package. The best obtained equations involve only five descriptors, which encode electronic properties of…

Masteroppgave i helse- og sosialinformatikk HSI 500 Universitetet i Agder 2014 Implementation of personnel staffing and scheduling information systems receives growing attention both nationally and internationally. Goals include improvement of the efficiency and effectiveness of scheduling activities. Standardized scheduling activities, is expected to improve the quality of management information. The purpose of this study is to evaluate the implementation of Gat as a personnel staffing and scheduling information system at Sørlandet Sykehus HF. Data material was gathered through a quantitative survey based on defined scheduling activities through the RAPS-tutorial. The questions were catego…
Parallel macro pipelining on the intel SCC many-core computer
2013
In this paper we present how Intel's Single-Chip-Cloud processor behaves for parallel macro pipeline applications. Subsets of the SCC's available cores can be arranged as a pipeline where each core processes one stage of the overall workload. Each of the independent cores processes a small part of a larger task and feeds the following core with new data after it finishes its work. Our case-study is a parallel rendering system which renders successive images and applies different filters on them. On normal graphics adapters this is usually done in multiple cycles, we do this in a single pipeline pass. We show that we can achieve a significant speedup by using multiple parallel pipelines on t…
Gaistošo organisko savienojumu emisijas no kuņģa vēža audiem un to potenciālā bioloģiskā saistība
2018
Gaistošā organiskā savienojuma (VOC) emisija, ko var novērot izelpā, ir strauji augoša diagnostikas metode audzēju izmeklēšanā. VOC ir savienojums, kam istabas temperatūrā ir augsts tvaika spiediens, kas veicina tā iztvaikošanu gāzes formā. Šo gāzi var noteikt cilvēka audos un šķidrumos.( Haick et al 2014) Galvenokārt ir pētīta VOC saistība ar plaušu vēzi. Taču aizvien vairāk tiek veikti pētījumi, lai noteiktu, kādas ir iespējas VOC pielietot arī kuņģa audzēja gadījumā. Tā kā VOC molekula spēj mijiedarboties ar šūnu metabolītiem, apkārtējo vido, mikrobiem u.c., ir grūti saprast tā rašanās vietu. Šajā pētījumā tiks izmeklētas potenciālās savienojuma vietas, no kurām tas cēlies. Ir dažādi vie…
