SEB bankas finanšu pakalpojumu analīze
2020
Bakalaura darba tēma ir “SEB bankas finanšu pakalpojumu analīze”. Latvijā šobrīd finanšu pakalpojumus piedāvā 13 komercbankas, tādēļ, lai veiksmīgi darbotos, bankai ir svarīgi nostiprināt savu pozīciju Latvijas finanšu tirgū, nepārtraukti attīstoties, piesaistot jaunus klientus, kā arī piedāvājot saviem klientiem jaunus un izdevīgus pakalpojumus. Bakalaura darba mērķis ir, pamatojoties uz speciālo literatūru, izpētīt komercbanku darbības nozīmi tautsaimniecībā, analizēt SEB bankas finanšu pakalpojumus, atklāt pozitīvos momentus un trūkumus pakalpojumu nodrošināšanā un kvalitātē, kā arī izstrādāt priekšlikumus finanšu pakalpojumu nodrošināšanas uzlabošanai. Pētījums norāda, ka SEB banka klie…
Inhibition of VEGF expression through blockade of Hif1a and STAT3 signalling mediates the anti-angiogenic effect of melatonin in HepG2 liver cancer c…
2013
Background: Hepatocellular carcinoma (HCC) growth relies on angiogenesis via vascular endothelial growth factor (VEGF) release. Hypoxia within tumour environment leads to intracellular stabilisation of hypoxia inducible factor 1 alpha (Hif1α) and signal transducer and activator of transcription (STAT3). Melatonin induces apoptosis in HCC, and shows anti-angiogenic features in several tumours. In this study, we used human HepG2 liver cancer cells as an in vitro model to investigate the anti-angiogenic effects of melatonin. Methods: HepG2 cells were treated with melatonin under normoxic or CoCl2-induced hypoxia. Gene expression was analysed by RT–qPCR and western blot. Melatonin-induced anti-…
Protective effect of adenylate deaminase (from Penicillium lanoso-viride) against acute infections in mice
1996
We examined the effects of the immunomodulator-adenylate deaminase (E.C. 3.5.4.6) from Penicillium lanoso-viride on experimental mice infections. Prophylactic intraperitoneal administration of adenylate deaminase (ADA) increased survival time and numbers of survivors after infection with Salmonella typhimurium, Pseudomonas aeruginosa and influenza A (H3N2) virus. Protection against influenza virus after intranasal ADA application was also observed. The influence of ADA was time and dose dependent. The most pronounced protection was obtained by administration of 3 U ADA/mice 24 h prior to infection. ADA had no antibiotic effect against these bacterial strains. Protective effects of ADA were …

Photochemical sample treatment for extracts clean up in PCB analysis from sediments.
2013
Sample purification can be considered the most polluting step of the whole analytical process for PCBs determination in sediment samples. The use of photochemical sample treatment represents an alternative methodology for extracts clean up allowing for a reduction of the used amount of organic solvents. The first application of a photochemical sample treatment for the selective removal or reduction of organic substances interfering with PCBs analyses in sediments is reported. The method's efficiency and robustness were compared with currently used chromatographic purification. Quality parameters such as recovery, linearity and reproducibility were studied. The entire procedure was validated…
Vācbaltiešu ietekme uz likumdošanas procesu Satversmes sapulces laikā
2016
Bakalaura darbs “Vācbaltiešu ietekme uz likumdošanas procesu Satversmes sapulces laikā” ir veltīts vācbaltiešu deputātu darbības analīzei Satversmes Sapulcē, izstrādājot Latvijas Republikas Satversmi un agrārās reformas likumu. Darba izstrāde tiek balstīta uz Satversmes Sapulces stenogrammās iekļauto informāciju. Vācbaltieši uzskatīja, ka Satversmē bija nepieciešams noteikt lielākas pilnvaras Valsts prezidentam, nevis parlamentārajai varai, norādot, ka šādi tiktu realizētas visas tautas intereses. Darbā tiek konstatēts, ka vācbaltiešu deputāti nespēja ietekmēt agrārā likumu izstrādāšanu, kā rezultātā vācbaltieši Latvijā cieta ievērojamus finansiālos zaudējumus, kā arī zaudēja priviliģētās g…
The Isgur-Wise function from the lattice
1995
We calculate the Isgur-Wise function by measuring the elastic scattering amplitude of a $D$ meson in the quenched approximation on a $24^3\times48$ lattice at $\beta=6.2$, using an $O(a)$-improved fermion action. Fitting the resulting chirally-extrapolated Isgur-Wise function to Stech's relativistic-oscillator parametrization, we obtain a slope parameter $\rho^2=1.2+7-3. We then use this result, in conjunction with heavy-quark symmetry, to extract $V_{cb}$\ from the experimentally measured $\bar B\to D^*l\bar\nu\,$\ differential decay width. We find $|V_{cb}|\sqrt{\tau_B/1.48{\mathrm ps}}= 0.038 +2-2 +8-3, where the first set of errors is due to experimental uncertainties, while the second …

Comparison of stable isotope composition and inorganic and organic contaminant levels in wild and farmed bluefin tuna, Thunnus thynnus, in the Medite…
2009
Abstract Stable isotope composition (δ13C and δ15N) and persistent pollutants, including heavy metals (Hg, Cd, Pb, As, Cu, Zn) and organochlorine compounds (PCBs, HCB and p,p′-DDE), were measured in muscle and liver tissues of wild and farmed bluefin tunas to investigate the changes occurring during the farming period and to assess the quality, in terms of contaminants, of the final product. At the end of farming, the food supplied was clearly integrated into the tuna tissues as derived from stable isotope signatures, and, contrarily to the literature findings obtained for other species, farmed tunas showed slight variations in persistent elements and chemical compounds in comparison with w…
