Veselīga dzīvesveida nodrošināšanas iespējas sākumskolas vecuma skolēniem
2021
Bakalaura darba tēma ir “Veselīga dzīvesveida nodrošināšanas iespējas sākumskolas vecuma skolēniem.” Temats izvēlēts, lai izpētītu, kādas ir veselības pamatnostādnes sākumskolas vecumā un kādas ir skolas, ārpusskolas aktivitāšu un ģimenes iespējas veselīgu ieradumu veidošanā. Tika pētīti skolēnu veselīga dzīvesveida noteicošie faktori un patiesie paradumi. Studiju darba teorijas izpētes daļā tika apskatītas un salīdzinātas dažādu autoru atziņas par veselīgu dzīvesveidu sākumskolas vecuma skolēniem, tā variācijām, ietekmējošajiem aspektiem un procesa attīstību kopumā. Praktiskajā pētījumā tika radīta un publicēta aptauja, kas sastāv no 22 jautājumiem par dažādiem veselīga dzīvesveida aspekti…
Dexamethasone premedication suppresses vaccine-induced immune responses against cancer
2020
ABSTRACT Glucocorticosteroids (GCS) have an established role in oncology and are administered to cancer patients in routine clinical care and in drug development trials as co-medication. Given their strong immune-suppressive activity, GCS may interfere with immune-oncology drugs. We are developing a therapeutic cancer vaccine, which is based on a liposomal formulation of tumor-antigen encoding RNA (RNA-LPX) and induces a strong T-cell response both in mice as well as in humans. In this study, we investigated in vivo in mice and in human PBMCs the effect of the commonly used long-acting GCS Dexamethasone (Dexa) on the efficacy of this vaccine format, with a particular focus on antigen-specif…
Tube transport of water vapor with condensation and desorption
2013
Attenuation and delay of active tracers in tube transport is an important current problem, but its full explanation is still lacking. To this end a model is introduced, where part of a tracer undergoes condensation and evaporation, treated as a diffusion-type process, in addition to Taylor dispersion. Condensation of water was verified by high-speed imaging, and the model solution fitted the breakthrough curves of laboratory measurements with pulses of water vapor of varying relative humidity. The model provides a transfer function whose performance was verified against field measurements. peerReviewed
Atsavināšanas sabiedrības vajadzībām tiesiskā regulējuma problēmas un iespējamie risinājumi.
2019
Bakalaura darba mērķis ir izpētīt atsavināšanas sabiedrības vajadzībām tiesiskā regulējuma problēmas un identificēt iespējamos risinājumus. Darba pirmajā daļā autore pēta īpašumu kā tiesību institūtu un tā mijiedarbību ar atsavināšanu sabiedrības vajadzībām. Darba otrajā daļā tiek analizēts atsavināšanas sabiedrības vajadzībām tiesiskais regulējums, aplūkojot gan tiesības uz īpašumu starptautiskajos cilvēktiesību dokumentos, gan Latvijas tiesisko regulējumu par īpašuma atsavināšanu sabiedrības vajadzībām. Trešajā daļā tiek analizēts taisnīgas atlīdzības saturs, kompensācijas veidi atsavināšanas sabiedrības vajadzībām problemātikas kontekstā un sniegti priekšlikumi. Darba apjoms ir 40 lapasp…

Task-Specific Organic Salts and Ionic Liquids Binary Mixtures: A Combination to Obtain 5-Hydroxymethylfurfural From Carbohydrates
2019
The increase in energy demand and depletion of fossil fuels are among major issues of modern society. Valorization and transformation of raw materials in products of industrial value represents a challenge. This justifies the growing interest of scientific research towards the identification of suitable media and methodologies able to pursue above goals, paying attention to matter of sustainability. On this subject, we studied sulfonic-acid functionalized diimidazolium salts as catalysts for the conversion of fructose and sucrose to 5-hydroxymethylfurfural (5-HMF) in an ionic liquid mixture. In general, using these salts allowed us to obtain 5-HMF in good yields from both substrates in mild…
Saliva in Food … How does it drive sensory perception?
2014
Saliva is a highly complex body fluid composed of many proteins, peptides, small organic molecules and ions. Saliva is produced and secreted by major and minor salivary glands to protect the mouth and to participate to the digestion. Generally distinction is made between resting saliva that is a result of autonomic stimulation, and stimulated saliva that is produced during chewing and taste stimulation. The link between saliva and sensory perception can be thus regarded through two main angles: the role of resting saliva as a background taste and the mechanistic role of saliva during eating. Indeed resting saliva (and its components) is continuously bathing our oral cavity and as such stimu…
Flavour & saliva interaction – a brief overview
2015
Saliva is a highly complex body fluid composed of many proteins, peptides, small organic molecules and ions. Saliva is secreted at rest and during eating by major and minor salivary glands. Resting saliva is continuously bathing our oral cavity and as such stimulates our taste receptors playing thus a role in taste sensitivity against some active taste substances. Beside, during eating, foods are chewed and a significant level of stimulated saliva is rapidly incorporated in the bolus. This in-mouth phenomena impact on flavor release and thus perception through saliva-food physical interactions but also through the action of biological compounds (enzymes mainly) against the food matrix. Sali…
Indistinguishability of Elementary Systems as a Resource for Quantum Information Processing.
2017
Typical elements of quantum networks are made by identical systems, which are the basic particles constituting a resource for quantum information processing. Whether the indistinguishability due to particle identity is an exploitable quantum resource remains an open issue. Here we study independently prepared identical particles showing that, when they spatially overlap, an operational entanglement exists which can be made manifest by means of separated localized measurements. We prove this entanglement is physical in that it can be directly exploited to activate quantum information protocols, such as teleportation. These results establish that particle indistinguishability is a utilizable …
