Available Lysine in Protein, Assay Using o-Phthalaldehyde/ N-Acetyl-L-cysteine Spectrophotometric Method
1992
An assay was based on reaction of free e-amino groups in proteins with the o-phthalaldehyde/N-acetyl-L-cysteine reagent to form isoindoles, which absorb at 335 nm. The procedure was suitable for proteins or mixtures of proteins with available lysine contents of more than 5 moles lysine/mole protein and required absence of free amino acids and peptides. This method was simpler and more convenient than other methods, since it did not require hydrolysis, amino acid analysis, long heating periods or solvent extraction.

A new efficient, highly dispersed, Pd nanoparticulate silica supported catalyst synthesized from an organometallic precursor. Study of the homogeneou…
2018
[EN] A new Pd(0) catalyst supported on silica UVM-7 has been synthesized from the organometallic [Pd-2(mu-(C6H4) Pp(2))(2)(CH3CN)(4)](BF4)(2) precursor, characterized by the high dispersion, activity, and small size of the palladium nanoclusters fixed on the silica surface. The catalyst was tested for the Suzuki-Miyaura (SM) reaction of different 4-substitutedphenyl halides with phenylboronic acid. The kinetic study concurs with most of the catalytic action was carried out by Pd species originated by the partial solubilization of Pd immobilized on mesoporous silica. The Schmidt's analysis of differential selectivity (SADS) in several competitive SM reactions, together the STEM-HAADF and HRT…
What drives diners' eco-friendly behaviour? The moderating role of planning routine
2021
Research focusing on diners' intentions towards leftovers, which are considered one of the main sources of consumer food waste in restaurants, is still at a nascent stage and requires further investigation. The present study attempts to address this gap by investigating the antecedents of diners' intentions to take away leftovers and thereby mitigate food waste in an out-of-home setting. Towards this end, we examined the role of personal and social norms as antecedents of the facilitators, inhibitors, and intentions of taking away leftovers. Using the theoretical lens of the Stimulus-Organism-Response (SOR) paradigm, we tested the proposed hypotheses by analysing data collected from 281 din…

Cannabis and Psychosis: A Causal Association
2021
Nowadays, the use of cannabis is widespread around the world and THC content of confiscated cannabis has increased in the last years. This fact has raised some consequences, especially in the mental health of the people. Although there have existed some initial controversies about the relationship between cannabis and psychosis, at the present time there are some certainties of the causal association between them. Through the Bradford Hill postulates, we will try to demonstrate that cannabis produces psychosis. The strength of the association, the consistency along the studies, biological gradient, temporality, plausibility, coherence, experimentation, and analogies support the cause-effect…
Valūtas kursa ietekme uz Latvijas ārējās tirdzniecības bilanci
2020
Ārējās tirdzniecības bilance ir viens no svarīgākajiem rādītājiem, lai analizētu valsts ārējo tirdzniecību, kā arī tā ir svarīga daļa no maksājumu bilances. Latvijas ārējās bilances saldo jau vairākus gadus ir bijis negatīvs (Pēc pasaules bankas datiem), tāpēc šajā darbā tiek apskatīts kādi faktori vispār ietekmē ārējo tirdzniecības bilanci un kā valūtas kurss teorētiski varētu ietekmēt valsts ārējo tirdzniecības bilanci. Diplomdarba mērķis ir izvērtēt valūtas kursa ietekmi uz Latvijas ārējo tirdzniecību no 1995. gada līdz 2018. gadam, balstoties uz reālo efektīvo valūtas kursu, Latvijas IKP uz vienu iedz. un ārzemju eksporta partneru IKP. Pirmajā nodaļā vispārīgi tiek aprakstīta ārējā tird…
Sistēmu pārvaldīšanas platformas "Atlas" pilnveidošana
2021
Kvalifikācijas darba ietvaros tika izstrādāta Latvijas Bankas sistēmai “Atlas” jauna komponente “universālā ievadforma”. Komponentes mērķis ir ļaut veikt CRUD darbības ar dažādiem viena līmeņa objektu veida datiem pie nosacījuma, ka komponentes konfigurācijā ir norādīts konkrēts tīmekļa API jeb biznesa sistēma, kas nodrošina konkrēta datu veida CRUD darbību izpildi. Tādā veidā uz šīs komponentes pamata var izstrādāt datu rediģēšanas formas priekš dažādām lietotāju vajadzībām un datiem.
