Effect of temperature on anaerobic treatment of black water in UASB-septic tank systems
2007
The effect of northern European seasonal temperature changes and low temperature on the performance of upflow anaerobic sludge blanket (UASB)-septic tanks treating black water was studied. Three UASB-septic tanks were monitored with different operational parameters and at different temperatures. The results indicated the feasibility of the UASB-septic tank for (pre)treatment of black water at low temperatures with respect to removal of suspended solids and dissolved organic material. Inoculum sludge had little effect on COD(ss) removal, though in the start-up phase some poorly adapted inoculum disintegrated and washed out, thus requiring consideration when designing the process. Removal of …
Synthesis, Characterization, and Properties of Weakly Coordinating Anions Based on tris-Perfluoro-tert-Butoxyborane
2017
Abstract Image A convenient method for the preparation of strongly Lewis acidic tris-perfluoro-tert-butoxyborane B(ORF)3 (1), (ORF = OC(CF3)3) was developed, and its X-ray structure was determined. 1 was used as a precursor, guided by density functional theory (DFT) calculations and volume-based thermodynamics, for the synthesis of [NEt4][NCB(ORF)3] (3) and [NMe4][FB(ORF)3] (5) and the novel large and weakly coordinating anion salts [Li 15-Crown-5][B(ORF)4] (2) and [NEt4][CN{B(ORF)3}2] (4). The stability of [B(ORF)4]− was compared with that of some related known weakly coordinating anions by appropriate DFT calculations. peerReviewed

Consumption of ultra-processed foods : an assessment of the literature on determinants of ultra-processed food consumption and an investigation of th…
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Background Highly processed foods have been classified as ultra-processed, and consumption of such foodstuffs have expanded rapidly over the last decades. Ultra-processed foods are characterized as being accessible, attractive, palatable and often time-saving. An excess intake of ultra-processed foods has been associated with increased risk of e.g. overweight/obesity and diabetes type II. The aim of this master’s project was to investigate factors influencing consumption of ultra-processed foods. This resulted in one review paper on young adults, and one cross-sectional study where the association between time scarcity and ultra…

Māsu stereotipi par HIV/AIDS pacientiem
2022
Bakalaura darbs “Māsu stereotipi par HIV/AIDS pacientiem”. Tēmas aktualitāti pamato, ka 2020. gadā Latvija ierindojās otrajā vietā Eiropā ar jaunatklātiem HIV gadījumiem. Daudzi ārvalstu pētījumi liecina, ka ar HIV saistītā negatīvā attieksme pret PLWH māsu vidū kavē HIV profilaksi un ārstēšanu. Zināšanas, izglītības līmenis, pieredze aprūpē ar HIV pacientiem, ir nozīmīgi faktori stigmai. Tādēļ pētījuma mērķis ir noskaidrot māsu stereotipus par HIV/AIDS pacientiem. Darbā tika analizēta literatūra par HIV/AIDS un stereotipiem, kas vērsti pret HIV/AIDS pacientiem, un Dž. Vatsones māszinības teorija. Pētījuma veikšanai izmantota kvantitatīva, šķērsgriezuma metode, instruments – aptauja, kurā p…

Obesity and survival in operable breast cancer patients treated with adjuvant anthracyclines and taxanes according to pathological subtypes: a pooled…
2013
Obesity is an unfavorable prognostic factor in breast cancer (BC) patients regardless of menopausal status and treatment received. However, the association between obesity and survival outcome by pathological subtype requires further clarification. METHODS: We performed a retrospective analysis including 5,683 operable BC patients enrolled in four randomized clinical trials (GEICAM/9906, GEICAM/9805, GEICAM/2003-02, and BCIRG 001) evaluating anthracyclines and taxanes as adjuvant treatments. Our primary aim was to assess the prognostic effect of body mass index (BMI) on disease recurrence, breast cancer mortality (BCM), and overall mortality (OM). A secondary aim was to detect differences o…
Grain Composition and Functional Ingredients of Barley Varieties Created in Latvia
2015
Abstract Cereals, including barley, have been recognised as functional foods that provide beneficial effect on the health of the consumer and decrease the risk of various diseases. The aim of investigation was to determine the grain composition of barley varieties and perspective breeding lines bred in Latvia and to evaluate its functional ingredients. The results of analysis showed that protein content among varieties ranged from 106.6-146.8 g·kg-1, total dietary fibre 187.4-208.2 g·kg-1, β-glucans 42.8 g-49.4 g·kg-1, and amount of α-tocopherol 6.03-8.93 mg·kg-1. The sum of essential amino acids in barley grain samples was from 32.90 g·kg-1 to 38.71 g·kg-1. All varieties of hulled and hull…
Creixement cristal·lí mitjançant la tècnica MOCVD i caracterització morfològica i estructural dels òxids de cadmi i zinc
2019
L'òxid de cadmi (CdO) i l'òxid de zinc (ZnO) han estat postulats com dos materials amb gran potencialitat en un ampli ventall d'aplicacions tecnològiques. Pel que fa a les seues propietats físiques, ambdós presenten un caràcter semiconductor de tipus “n”, sense dopatge intencionat. A més, el seu bandgap directe a 2.2 i 3.3 eV, respectivament, asseguren un bon grau de transparència òptica en la regió infraroja i visible de l'espectre electromagnètic. La projecció d'aquests compostos en camps com la plasmònica o les tecnologies basades en transicions intersubbanda fa convenient el control per a l'obtenció de capes molt primes. Malgrat això, gairebé tots els treballs publicats reporten capes p…
