Synthesis, Optical, and Morphological Studies of ZnO Powders and Thin Films Fabricated by Wet Chemical Methods
2020
Zinc oxide nanoparticles were prepared from Zn5(CO3)2(OH)6 precursor, capped with poly(vinylpyrrolidone) (PVP), and annealed at 600 °
Interactive methods for multiobjective robust optimization
2018
Practical optimization problems usually have multiple objectives, and they also involve uncertainty from different sources. Various robustness concepts have been proposed to handle multiple objectives and the involved uncertainty simultaneously. However, the practical applicability of the proposed concepts in decision making has not been widely studied in the literature. Developing solution methods to support a decision maker to find a most preferred robust solution is an even more rarely studied topic. Thus, we focus on two goals in this thesis including 1) analyzing the practical applicability of different robustness concepts in decision making and 2) developing interactive methods for sup…
Virtues for innovativeness : a mixed methods study of ethical organisational culture and organisational innovativeness
2016
Artikkeliväitöskirja. Sisältää yhteenveto-osan ja neljä artikkelia. Article dissertation. Contains an introduction part and five articles. This study examined ethical organisational culture, consisting of ethical organisational virtues, and organisational innovativeness. More specifically, the study explored the relationship between the phenomena. Ethical organisational culture was studied using Corporate Ethical Virtues (CEV) model, which is based on the virtue theory of business ethics. This research makes a contribution to prior research on ethical organisational culture by linking the concept of organisational innovativeness (OIN) to it. The overall goal of this study was to increase th…
Cilvēku tirdzniecības krimināltiesiskais raksturojums Latvijā un ārvalstīs
2016
Cilvēku tirdzniecība ir noziegums, kas mūsdienās skar ikvienu pasaules valsti. Katru gadu aptuveni 4 miljoni cilvēku tiek pārdoti un nonāk verdzības stāvoklī. Lai arī ir pagājuši vairāki gadsimti, kopš verdzība oficiāli ir atcelta, joprojām- cilvēki pārdod cilvēkus. Darba mērķis ir analizēt starptautiskā un nacionālā mēroga normatīvos aktus un vērst uzmanību uz katra uzdevumu un nozīmi cilvēku tirdzniecības apkarošanā; pētīt kaimiņvalstu normatīvo regulējumu cīņā pret cilvēku tirdzniecību, analizēt Latvijas tiesu praksi un konstatēt aktuālos problēmjautājumus; baltoties uz pētījuma rezultātā gūtajiem secinājumiem, sniegt priekšlikumus grozījumu veikšanai Krimināllikumā. Mērķa sasniegšanai t…
Studiju metodiķes darba automatizēšana
2021
Kvalifikācijas darba “Studiju metodiķes darba automatizēšana” mērķis bija atrast, izstrādāt un dokumentēt IT risinājumu, kas pēc iespējas efektīvāk varētu palīdzēt Datorikas fakultātēs Bakalaura studiju metodiķes ikdienas gaitās. Par sistēmas pamatu tika izvēlēta atklātā pirmkoda sistēma osTicket, kura ļauj reģistrēt lietotājus, un ērtā un efektīvā veidā dod iespēju apstrādāt lietotāju pieprasījumus. Sistēma ir veidota izmantojot PHP programmēšanas valodu. Kvalifikācijas darba ietvaros tika izstrādāta minimālā sistēma eksperimentālās ekspluatācijas sākumam.

Molluscan antimicrobial peptides, a review from activity-based evidences to computer-assisted sequences
2011
Antimicrobial peptides (AMPs) represent the most universal immune effectors. Molluscs constitute the second largest animal phylum, after Arthropods, in term of number of species. Only a negligible number has been investigated regarding AMPs. The choice of the species to be studied relied on their economical importance and availability. First studies on molluscan AMPs dated from 1996 and were based on biological activities of biochemical-purified fractions. Such approach released all the original structures we know, with biological activity sometimes different from one isoform to another. Then, molecular biology techniques were applied to molluscan AMPs starting in 1999. Complete screening o…
Finite groups with all minimal subgroups solitary
2016
We give a complete classification of the finite groups with a unique subgroup of order p for each prime p dividing its order. All the groups considered in this paper will be finite. One of the most fruitful lines in the research in abstract group theory during the last years has been the study of groups in which the members of a certain family of subgroups satisfy a certain subgroup embedding property. The family of the subgroups of prime order (also called minimal subgroups) has attracted the interest of many mathematicians. For example, a well-known result of Itˆo (see [8, Kapitel III, Satz 5.3; 9]) states that a group of odd order with all minimal subgroups in the center is nilpotent. Th…
Cell-cycle control in cell-biomaterial interactions
2000
Current biocompatibility testing involves the demonstration of cell proliferation, which is usually interpreted as a sign of positive biocompatibility when the materials sustain cell proliferation. As the field of biomaterials research is rapidly moving toward tissue-engineered devices and hybrid organs, control of cell function has become a main topic. Cell function, which involves specific differentiation pathways, cannot be separated from cell-cycle control. The study of cell-cycle control is an important extension of routine proliferation assays and has extensive roots in developmental and tumor biology. We studied the expression of the tumour suppressor gene p53 and the proliferation-a…
Measurement of the average shape of longitudinal profiles of cosmic-ray air showers at the Pierre Auger Observatory
2019
The profile of the longitudinal development of showers produced by ultra-high energy cosmic rays carries information related to the interaction properties of the primary particles with atmospheric nuclei. In this work, we present the first measurement of the average shower profile in traversed atmospheric depth at the Pierre Auger Observatory. The shapes of profiles are well reproduced by the Gaisser-Hillas parametrization within the range studied, for E>10 17.8 eV .A detailed analysis of the systematic uncertainties is performed using ten years of data and a full detector simulation. The average shape is quantified using two variables related to the width and asymmetry of the profile, and …
