Saistītu reāla laika sistēmu testēšana, izmantojot lietotāja uzvedības imitēšanu
2018
Programmatūras testēšana ir ārkārtīgi svarīga programmatūras izstrādes cikla sastāvdaļa, jo tas ir visefektīvākais veids, kā uzlabot programmatūras kavlitāti, atklājot tajā kļūdas. Aizvien izplatītāka kļūst automatizētā testēšana, kur, pretstatā manuālajai testēšanai, testēšanu veic bez cilvēka līdzdalības ar koda palīdzību. Bakalaura darba ietvaros ir apskatīti reāla laika sistēmu darbības principi, automatizētā testēšana un tās nozīme programmatūras izstrādāšanas procesā, kā arī pētīta pūļa uzvedība. Tika sastādīts automatizētā testa scenārijs un skripts, kas tika izmantots saistītu reāla laika sistēmu testēšanā un veikta testēšanas rezultātu analīze.
Testēšanas darbu izpildes laika noteikšanas metodoloģija
2019
Testēšanas darbu izpildes laiks ir būtiska informācijas tehnoloģiju projektu sastāvdaļa. Nepareizi noteikts testēšanas darbu izpildes laiks var novest pie vairākām negatīvām sekām, sākot no projekta izmaksu palielināšanas un nodevumu termiņu izmaiņām, beidzot ar projekta kopējās nerentablitātes sasniegšanu. Lai izvairītos no šādām sekām, eksistē vairākas pieejas, ar kuru palīdzību ir iespējams noteikt testēšanas ilgumu, tomēr industrijā nav vienota šī procesa standarta, kā arī katrai pieejai ir savi trūkumi, kas praksē noved pie tā, ka bieži vien testēšanas darbu ilgums nav noteikts precīzi. Bakalaura darba mērķis bija izveidot oriģinālu laika novērtējuma metodoloģiju, kas izdevīgi atšķiras…

Short-term effects of wood ants (Formica aquilonia Yarr.) on soil animal community structure
1999
Abstract Wood ants are known to affect the structure of invertebrate communities in tree canopies but it is not clear whether wood ants can affect the structure of soil animal communities. To isolate the direct effects of wood ants on soil fauna, I manipulated wood ant density in a 6-week mesocosm experiment by placing mesocosms (O 14 cm, height 13.5 cm) permeable to ants either on or outside the ant trails. The mesocosms contained litter, humus, and a diverse soil fauna typical of coniferous forest. I controlled earthworm species composition and biomasses by inoculating 470 mg fresh mass of epigeic lumbricid Dendrobaena octaedra (Sav.) or Dendrodrilus rubidus (Sav.) to the mesocosms. A 15-…
Cytotoxic Activity of Organotin(IV) Derivatives with Triazolopyrimidine Containing Exocyclic Oxygen Atoms
2020
In this study cytotoxicity of organotin(IV) compounds with 1,2,4-triazolo[1,5-a]pyrimidines, Me3Sn(5tpO) (1), n-Bu3Sn(5tpO) (2), Me3Sn(mtpO) (3), n-Bu3Sn(mtpO) (4), n-Bu3Sn(HtpO2) (5), Ph3Sn(HtpO2) (6) where 5HtpO = 4,5-dihydro-5-oxo-[1,2,4]triazolo-[1,5-a]pyrimidine, HmtpO = 4,7-dihydro-5-methyl-7-oxo-[1,2,4]triazolo-[1,5-a]pyrimidine, and H2tpO2 = 4,5,6,7-tetrahydro-5,7- dioxo-[1,2,4]triazolo-[1,5-a]-pyrimidine, was assessed on three different human tumor cell lines: HCT-116 (colorectal carcinoma), HepG2 (hepatocarcinoma) and MCF-7 (breast cancer). While 1 and 3 were inactive, compounds 2, 4, 5 and 6 inhibited the growth of the three tumor cell lines with IC50 values in the submicromolar …
TAPPARELLA AVVOLGIBILE A SISTEMA DESMODROMICO
2017
La presente invenzione riguarda una tapparella avvolgibile a sistema desmodromico. La tapparella della presente invenzione è dotata di un meccanismo che consente l'apertura delle lamelle sfruttando il peso stesso della tapparella. L'apertura delle lamelle viene attuata grazie alla particolare geometria del meccanismo e mediante l'interazione tra le guide e le parti scorrevoli della tapparella. La sua geometria riesce a determinare l’apertura o la chiusura delle lamelle. The present invention relates to a roller shutter with a desmodromic-system. The shutter of the present invention is provided with a mechanism allowing the slats to be opened by exploiting the weight of the blind itself. The…
On Shimura subvarieties generated by families of abelian covers ofP1
2018
We investigate the occurrence of Shimura (special) subvarieties in the locus of Jacobians of abelian Galois covers of P1 in Ag and give classifications of families of such covers that give rise to Shimura subvarieties in the Torelli locus Tg inside Ag. Our methods are based on Moonen–Oort works as well as characteristic p techniques of Dwork and Ogus and Monodromy computations.
Studies on a new potential dopaminergic agent: in vitro BBB permeability, in vivo behavioural effects and molecular docking evaluation.
2015
2-Amino-N-[2-(3,4-dihydroxy-phenyl)-ethyl]-3-phenyl-propionamide (DA-PHEN) has been previously synthesized to obtain a potential prodrug capable of release dopamine (DA) into CNS. However, DA-PHEN could act per se as a dopaminergic drug. In this study, the permeability transport (Pe), obtained by parallel artificial permeability assay (PAMPA), indicated a low passive transcellular transport (Pe = 0.32 ± 0.01 × 10(-6 )cm/s). Using the Caco-2 cell system, the Papp AP-BL in absorptive direction (3.36 ± 0.02 × 10(-5 )cm/s) was significantly higher than the Papp BL-AP in secretive direction (1.75 ± 0.07 × 10(-5 )cm/s), suggesting a polarized transport. The efflux ratio (Papp AP-BL/Papp BL-AP = 0…
Bisphosphonate prodrugs utilizing endogenous carriers
2016
Targeting of therapeutic agents to a specific site, as well as controlling the rate and time of release, has been intensively investigated and established over the last decades. These studies concerning drug delivery systems led to the formulation of several products that can improve the diffusion across the barriers after drug administration. For this purpose, the development of strategies of novel drug delivery systems for bisphosphonates had taken hold to improve both the bioavailability and safety. Firstly, they have been used for over a century in the branch of industry and later, in the 1960s, in medicine. Bisphosphonates are synthetic compound analogs to the naturally occurring pyrop…
