No ķirurģiskā materiāla izdalīto Klebsiella spp. baktēriju β-laktamāžu producēšanas noteikšana
2021
Klebsiella pneumoniae un Klebsiella oxytoca ir Gram-negatīvas nosacīti patogēnas baktērijas, kas izraisa urīnceļu, plaušu u.c. orgānu infekcijas. Klebsiella spp. raksturo plaša rezistence pret β-laktāmu antibakteriālajiem līdzekļiem, kur klīniski nozīmīgāka ir paplašināta darbības spektra β-laktamāze (ESBL). Darbā apkopota literatūra par Klebsiella spp. morfoloģiju, infekcijām, antibakteriālu terapiju un tās rezistences mehānismiem. Praktiskajā daļā tika iegūti Klebsiella spp. antibakteriālas jutības dati, pamatojoties uz disku difūzijas testiem (DDT), E-testiem, un arī lietojot molekulārbioloģiskās izmeklēšanas metodes: DNA STRIP® tehnoloģiju. Pētījums tika veikts Rīgas Traumatoloģijas un …
Mechanism of the Citrate Transporters in Carbohydrate and Citrate Cometabolism in Lactococcus and Leuconostoc Species
1998
ABSTRACT Citrate metabolism in the lactic acid bacterium Leuconostoc mesenteroides generates an electrochemical proton gradient across the membrane by a secondary mechanism (C. Marty-Teysset, C. Posthuma, J. S. Lolkema, P. Schmitt, C. Divies, and W. N. Konings, J. Bacteriol. 178:2178–2185, 1996). Reports on the energetics of citrate metabolism in the related organism Lactococcus lactis are contradictory, and this study was performed to clarify this issue. Cloning of the membrane potential-generating citrate transporter (CitP) of Leuconostoc mesenteroides revealed an amino acid sequence that is almost identical to the known sequence of the CitP of Lactococcus lactis . The cloned gene was exp…
Dynamic scheduling of periodic skippable tasks in an overloaded real-time system
2008
International audience; The need for supporting dynamic real-time environments where changes in workloads may occur requires a scheduling framework that explicitly addresses overload conditions, allows the system to achieve graceful degradation and supports a mechanism capable of determining the load to be shed from the system to handle the overload. In applications ranging from video reception to air-craft control, tasks enter periodically and have response time constraints, but missing a deadline is acceptable, provided most deadlines are met. Such tasks are said to be occasionally skippable and have an assigned skip parameter. We look at the problem of uniprocessor scheduling of skippabl…
The involvement of autistic children in early childhood education
2023
Research on the involvement of autistic children in daily activities in inclusive early childhood education is scarce. In Finland, all children, including autistic children, under the age of seven (before basic education) are entitled to participate in early childhood education and care. Children also attend compulsory, free-of-charge pre-primary education during the year before their basic education begins. Furthermore, attending early childhood education and care is not dependent whether a child requires day care because of their parents’ work. Autistic children attend early childhood education in inclusive day care centres. Thus, in this study, we examined the involvement of autistic chi…
Age-related operator deficits in a realistic instrument-control task: Assessment of possssible motor, cognitive and mental causes
2017
Abstract With advancing age, motor and mental functions gradually change. As these changes have been revealed by standardized laboratory tests, it remains unclear how much they affect older persons' performance in industrial workplace tasks. The present study therefore compared young and older participants in a task modeled after a complex, realistic industrial workplace scenario, and additionally assessed motor, cognitive and mental variables that might have an impact on overall task efficiency. 25 participants (13 young, mean age 25 years; 12 older participants, mean age 65 years) sat in front of a panel with multiple displays - indicating the momentary state of a simulated nuclear power …
EAGLE 2006 - Multi-purpose, multi-angle and multi-sensor in-situ and airborne campaigns over grassland and forest
2009
EAGLE2006 – an intensive field campaign for the advances in land surface hydrometeorological processes – was carried out in the Netherlands from 8th to 18th June 2006, involving 16 institutions with in total 67 people from 16 different countries. In addition to the acquisition of multi-angle and multi-sensor satellite data, several airborne instruments – an optical imaging sensor, an imaging microwave radiometer, and a flux airplane – were deployed and extensive ground measurements were conducted over one grassland site at Cabauw and two forest sites at Loobos and Speulderbos in the central part of the Netherlands. The generated data set is both unique and urgently needed for the developmen…

Tardigrades of Finland: new records and an annotated checklist
2020
Species checklists are powerful and important tools of communication between taxonomists and applied environmental biologists, which in turn lead to well-planned and successful conservation strategies and ecological studies. Despite this, only recently the interest on compiling systematic checklists is growing among taxonomists who study tardigrades—micrometazoans that inhabit almost every habitat worldwide. As the Finnish records of tardigrades (a.k.a. water bears) species are incomplete, outdated and no checklist has ever been compiled for this country, an easy-to-consult checklist is here reported. This checklist covers all Finnish tardigrade taxa identified in the past and in the 13 sam…
