Synthesis, electron microscopy and X-ray characterization of oxymagnesite, MgO·2MgCO3, formed from amorphous magnesium carbonate
2014
At present, the peculiar compound called oxymagnesite, MgO·2MgCO3, an intermediate formed during thermal decomposition of hydrated magnesium carbonates, has only been described a handful of times without a distinct description of its formation or morphology. In the current work we present the first scanning and transmission electron microscopy images of an oxymagnesite crystal together with its crystallographic data. Oxymagnesite was synthesized in a controlled manner via decomposition of amorphous magnesium carbonates (AMCs) subjected to varying relative humidity. We show that oxymagnesite is formed only when AMC is hydrated above a certain level, which we attribute to structural inequival…

Mīksto kontaktlēcu kopšanas šķīdumu antimikrobās aktivitātes salīdzinājums
2017
Maģistra darbs ir uzrakstīts latviešu valodā. Mērķis: novērtēt dažādu kontaktlēcu kopšanas šķīdumu dezinficējošo aktivitāti un to ietekmējošos faktorus. Uzdevumi: Novērtēt ekspozīcijas laika un uzglabāšanas temperatūras ietekmi uz kontaktlēcu kopšanas šķīduma darbības efektivitāti pret S.epidermidis. Metode: tika veikti mikrobioloģiskie uzsējumi un izaugušo koloniju uzskaitījums. Šķīduma efektivitāte tika pārbaudīta atkarībā no ekspozīcijas laika (30 minūtes, ražotāja ieteiktais minimālais dezinfekcijas laiks, diennakts, 3, 7 un 30 dienas) pie 22-23°C un 5-6°C temperatūras. Rezultāti: Visi līdzekļi uzrāda baktericīdu iedarbību pret S.epidermidis un saglabā šo efektu ilgtermiņā. Mīksto konta…
Mūzikas ģenerēšana, izmantojot neironu tīklus
2018
Kļūstot arvien populārākiem neironu tīkliem tie tiek pielietoti arvien dažādākās nozarēs tai skaitā mūzikā. Mūzikas ģenerēšanas sfērā visizplatītāk ir ģenerēt jaunu melodiju, nevis papildināt jau esošu. Darba mērķis ir izveidot sistēmu, kas pieģenerē jaunu melodiju klāt jau eksistējošai melodijai, veidojot harmonisku muzikālu saspēli. Mērķa īstenošanai tika izpētīti neironu tīklu veidi, to piemērotība mūzikas ģenerēšanai, salīdzināti dziesmu reprezentāciju veidi, apskatītas datu kopas un izraudzīta piemērotākā. Darba praktiskajā daļā tika izveidota sistēma, kas izmantojot neironu tīklus ģenerē jaunu melodiju balstoties jau uz es…
Les thermes, le ski, et puis la nuit. Des stations illuminées à la valorisation des ressources environnementales nocturnes dans les territoires touri…
2015
International audience; Les réflexion engagées par le Collectif RENOIR interrogent le devenir des territoires touristiques au regard d’un processus émergent : la considération de la nuit et du paysage nocturne dans les projets de territoires. La mise en scène de ce que nous appelons des « ressources environnementales nocturnes » est appréhendée comme point de départ pour l’observation des stations touristiques en transition.Ce processus s’accompagne de mutations profondes, qui trouvent leurs sources dans la remise en cause d’un éclairage urbain (monumental, de voirie, de sécurisation, etc.) focalisé, jusque dans les années 1980, sur des aspects quantitatifs. Les différentes fonctions de l’é…

UV-B exposure causes DNA damage and changes in protein expression in northern pike (Esox lucius) posthatched embryos.
2012
The ongoing anthropogenically caused ozone depletion and climate change has increased the amount of biologically harmful UV-B radiation, which is detrimental to fish in embryonal stages. The effects of UV-B radiation on the levels and locations of DNA damage manifested as cyclobutane pyrimidine dimers (CPDs), heat shock protein 70 (HSP70) and p53 protein in newly hatched embryos of pike were examined. Pike larvae were exposed in the laboratory to current and enhanced doses of UV-B radiation. UV-B exposure caused the formation of CPDs in a fluence rate-dependent manner, and the CPDs were found deeper in the tissues with increasing fluence rates. UV-B radiation induced HSP70 in epidermis, and…
Ethyl hexanoate transfer in paper and plastic food packaging by sorption and permeation experiments
2008
The barrier properties of one treated paper packaging and one standard plastic film (bi-oriented polypropylene, biOPP) were assessed for ethyl hexanoate. Three methods based either on sorption (gravimetry and micro-atmosphere-derived method) or permeation kinetic determination were used in controlled conditions of aroma vapor concentration (107 Pa), temperature (25 degrees C) and relative humidity (about 0 %). Ethyl hexanoate solubility values were on the same range of magnitude for both packaging films in spite of their different nature and composition. Ethyl hexanoate affinity for both films was well predicted by their respective solubility parameters. Solubility values were different acc…
Characterization of Erwinia gerundensis A4, an Almond-Derived Plant Growth-Promoting Endophyte
2021
The rapidly increasing global population and anthropogenic climate change have created intense pressure on agricultural systems to produce increasingly more food under steadily challenging environmental conditions. Simultaneously, industrial agriculture is negatively affecting natural and agricultural ecosystems because of intensive irrigation and fertilization to fully utilize the potential of high-yielding cultivars. Growth-promoting microbes that increase stress tolerance and crop yield could be a useful tool for helping mitigate these problems. We investigated if commercially grown almonds might be a resource for plant colonizing bacteria with growth promotional traits that could be use…
