From isolated 1H-pyrazole cryptand anion receptors to hybrid inorganic-organic 1D helical polymeric anion receptors
2015
We report a novel 1-D helical coordination polymer formed by protonated polyamine 1H-pyrazole cryptands interconnected by Cu2+ metal ions that are able to encapsulate anionic species behaving as a multianion receptor. Switching from a monomeric receptor to a polymeric receptor is activated by metal ions and pH.
Crypthecodinium cohnii metabolisma matemātiskā modelēšana DHA ražošanas optimizācijai
2020
Datormodelēšana un bioķīmisko ceļu simulēšana ir sistēmbioloģijas pamatnostādnes, un pastāv vairākas metodes, kas var palīdzēt šo sistēmu izpētīšanā. Darbā izmantota divu sistēmbioloģijas modelēšanas metožu pieeja šūnu taukskābju sintēzes metabolisma pētīšanai. Darba ietvaros izveidots kinētiskais modelis, kas ietver glikolīzes ceļa reakcijas un reakcijas, kas ved līdz taukskābju sintezējošajam enzīmam- FAS, kā arī pilnveidots genoma izmēra metaboliskais modelis dinoflagellātam Crypthecodinium cohnii. Kinētiskais modelis tika parametrizēts saskaņā ar pieejamajiem eksperimentālajiem datiem. Aplūkoti stehiometriskajā modelī ietvertie metabolisma regulācijas mehānismi taukskābju sintēzei un ga…

More is not always better—non-linear effects in crowdfunding
2019
Abstract This research focuses on crowdfunding project features and its relation with the success of this project. The main purpose is to improve probability of success of crowdfunding projects. One can argue that “more is always better” resulting in attempts of daily updates. Contrarily, backers may be weary of numerous updates to work through, indicating a possible wear-out effect, implying the existence of an optimal level of updates. Our preliminary results show that previous research, built upon linear modeling, widely ignores important aspects of the relationship between key variables. We therefore picked six key variables that were previously marked as success drivers in crowdfunding…
OBTAINING POSITIONS OF ASTEROIDS FROM DIGITIZED PROCESSING OF PHOTOGRAPHIC OBSERVATIONS IN BALDONE OBSERVATORY (CODE 069)
2016
Digital processing of photographic plates of star fields allows to determine with high accuracy the coordinates and stellar magnitudes for all registered objects on these plates. The processing results can be used for a broad search for images of small bodies of the Solar system and determination of their coordinates. From the observations of earlier epoch, we can extract information about the locations of these bodies well before discovering them. Modern approach to processing early photographic observations with new technologies can be an effective instrument for rediscovery of asteroids and correction their orbits. We analyzed the results of digital processing of observations of clusters…
From research question to dissemination: how to design, analyse and present study results
2018
Today, the term “study” is very frequently used in quite a broad sense: survey, clinical trial, analysis, research and other terms with deeply different meanings are often generally indicated as “studies”. A “study” can be generally defined as a process composed of several actions aimed to verify one or more hypotheses (objectives), with the ultimate goal of sharing the answers (results) with a target audience, in the form of a scientific paper, presentation or poster.

Leadership – A Key Factor to a Succesful Organization – Part II
2013
Abstract Leadership is the well-known and often discussed process nowadays of influence exerted by one person, accepted and followed by all, over the other factors (human resource) that he works with, in order to reach the organizational goals. This research is the second part of a long cycle aimed to determine the knowledge and application of the leadership concept in the Romanian organizations considering the influences imposed by the external environment, often characterized by frequent changes. These changes may have positive or negative effects on organizations, and that is why organizations have to react fast in order to take advantage of opportunities and to protect from threats. We …
Heading at Enabling Settings for Learning
2021
The paper draws on two cases of learning settings that were converted to meet up-to-date educational requirements within these learning contexts. The authors address the role of stakeholder perspectives. Focusing on the learning situation, they present an articulation tool to aid dialogue between key stakeholder perspectives in a (re)design process. Dialogue is a way to figure out relevant issues and to establish the common ground between participants. The goal of a redesign process is that user requirements are well understood, and the design is embedded into local practices, informed of constraints and aware of potential opportunities regarding educational technology.
Vienšūņa Cryptosporidium spp. izplatība un invāziju veicinošie faktori liellopos Latvijā
2018
Cryptosporidium spp. ir nozīmīgs, diareju izraisošais patogēns, kura invāziju ietekmējoši faktori un ekstensitāte liellopos ir maz pētīti Latvijas teritorijā. Bakalaura darba ietvaros, laika periodā no 2017. gada rudens līdz 2018. gada pavasarim, tika analizēti 135 paraugi no septiņām saimniecībām, četros vēsturiskos Latvijas reģionos (Kurzeme, Zemgale, Latgale, Vidzeme). Visi paraugi tika izmeklēti ar koproloģisko metodi - Cryptosporidium spp. koncentrāciju un sekojošu krāsošanu ar modificēto Ziehl-Neelsen metodi, ar mērķi, noteikt ekstensitāti Latvijas teritorijā un invāziju ietekmējošos faktorus. Katrā no saimniecībām tika veikta informācijas ievākšana par pētāmo dzīvnieku, tā dzīvošanas…
