Definition of the single integration site of the pathogenicity locus in Clostridium difficile.
1996
We determined the nucleotide sequence 3.8 kb upstream and 5.2 kb downstream of the toxin genes A and B of Clostridium difficile. Nine ORFs were discovered. Based on PCR-directed approaches, two were attributed to the pathogenicity locus (PaLoc). The other seven were found in every C. difficile isolate obtained from the human gastrointestinal tract, respectless of their toxinogenicity. The ORFs cdu1 and cdu2/2' upstream of the PaLoc displayed similarity to repressors of Gram-positive bacteria (cdu1), and to an Na+/H+ antiporter described for Enterococcus hirae (cdu2/2'). Downstream of the locus a putative ABC transporter (cdd2-4) was identified. With a set of three paired primers used in pol…
Micellar electrokinetic chromatography with bile salts for predicting ecotoxicity of aromatic compounds.
2004
The retention factors of several aromatic compounds were obtained by micellar electrokinetic chromatography (MEKC) using cholate, taurocholate, deoxycholate and deoxytaurocholate as micellar systems. The possibility of using these retention factors to describe and predict several ecotoxicological activities of different aromatic compounds was evaluated. Adequate correlations retention–ecotoxicity (log LC50 in fish and daphnia, log EC50 in green algae and daphnia, chronic values in fish and green algae, bioconcentration factor, and soil sorption coefficient) were obtained for the micellar systems studied. The predictive ability of the models obtained for these micellar systems was compared. …
Capturing daily family dynamics via text messages: development of the mobile diary
2010
In this paper we introduce a new tool, the mobile phone, for use in diary research. We demonstrate, with reference to two family studies conducted in Finland, how daily family dynamics can be captured by using the mobile diary. In both studies family members sent text messages (SMSs) in answer to structured diary questions three times a day over a one-week period. The participants kept also paper-and-pencil diaries. Two mobile diary items measuring mood (stressfulness and feelings of competence) both at home and at work are reported here as examples. For both items we found statistically significant daily and weekly variation as well as individual fluctuation. The data gathered by the mobil…
Mobilo ierīču apdrošināšanas produkta izveide un ieviešana sistēmā TIA.
2017
TIA ir globāla apdrošināšanas sistēma, kas pārvalda apdrošināšanas procesus no sākuma līdz beigām. Sākotnēji tā tika radīta priekš viena konkrēta uzņēmuma, bet tagad to izmanto plaši pasaulē. Darba mērķis bija izveidot un ieviest mobilo ierīču apdrošināšanas produktu uz TIA kodola versijas. Mobilo ierīču apdrošināšanas produkts tika plānots izveidot kā paraugu, kuru būtu iespējams realizēt nākotnē. Uzdevums bija izveidot produktu tā, ka tam būtu jābūt iespējai izvēlēties no saraksta konkrētu ierīču modeļus vai pievienot jaunus un aprēķināt tām prēmijas, izveidot polises. Tas tika realizēts ar 1 produkta līniju, kurā būs iespējams veikt minētās darbības. Darbā ir atrodams ne vien šī produkta…
Starpplatformu programmatūras izstrādes ietvaru pieeja mobilo lietotņu izveidei
2020
Ņemot vērā viedierīču arvien plašāko izmantošanu planētas iedzīvotāju ikdienā, mobilo lietotņu izstrādes bizness un lietotņu piedāvājums ir milzīgs, tāpēc arvien svarīgs kļūst jautājums par piemērotu tehnoloģiju izvēli lietotņu izveidē. Starp pieejamām tehnoloģijām ir gan tādas, kas ir nostabilizējušās un pastāv gadiem, gan salīdzinoši jaunas un attīstības fāzē esošas. Mobilo lietotņu izstrādātājam atbilstošas tehnoloģijas izvēle var būt nopietns uzdevums, kas potenciāli var novest pie problēmām projektam attīstoties. Darba mērķis ir izpētīt un pārbaudīt pēdējā laikā arvien populārāko starpplatformu ietvaru pieeju mobilo lietotņu izstrādē, īpaši fokusējoties uz jauno tehnoloģiju Flutter, ka…

dSDiVN: A Distributed Software-Defined Networking Architecture for Infrastructure-Less Vehicular Networks
2017
In the last few years, the emerging network architecture paradigm of Software-Defined Networking (SDN), has become one of the most important technology to manage large scale networks such as Vehicular Ad-hoc Networks (VANETs). Recently, several works have shown interest in the use of SDN paradigm in VANETs. SDN brings flexibility, scalability and management facility to current VANETs. However, almost all of proposed Software-Defined VANET (SDVN) architectures are infrastructure-based. This paper will focus on how to enable SDN in infrastructure-less vehicular environments. For this aim, we propose a novel distributed SDN-based architecture for uncovered infrastructure-less vehicular scenari…
Delay-oriented data traffic migration in maritime mobile communication environments
2012
Maritime ship-to-shore communication has to satisfy different user requirements while suffering dynamic communication circumstances. Satellite networks are the primary means to communicate between ship and shore. The idea of compensating the deficiency of satellite communication with other terrestrial networks is not new. However, focus was often on how to keep users always best connected, without considering respective application needs or the potential disconnections. In this paper, we propose a delay-oriented satellite data traffic migration solution, exploiting the route repetitiveness and predictability of ships, leveraging the delay tolerance of many communication applications, with t…
Mobile Encounter Network - the missing data link
2008
In this paper, we discuss about the applicability of a short-range wireless communication scheme called Mobile Encounter Network (MEN). Encounters between devices communicating while moving allows ad-hoc -type data transfer to be performed. A background for the emerging of such networks is given. The essential properties of the MEN data transfer are specified. Based on this, the role of MEN as a data transfer medium is discussed. The conclusion is that such networking technique may provide additional value compared to the traditional wireless communication.
