Sensorimotoro funkciju novērtēšana cilindra un stūra testā pelēm pēc modelēta insulta
2021
Insults ir akūta neiroloģiska disfunkcija, kas izraisa neiroloģiskas, sensorimotoras un uzvedības izmaiņas. Lai izprastu insulta patoloģiskos mehānismus un izstrādātu jaunas terapijas, insults tiek modelēts eksperimentāli. Stūra un cilindra uzvedības testus izmanto, lai novērtētu sensorimotorās funkcijas grauzējiem. Maģistra darba mērķis ir izvērtēt cilindra un stūra testa pielietojumu modelēta insulta gadījumā pelēm divu mēnešu periodā. Pētījumā secināts - lai mazinātu peļu pierašanu un neaktivitāti, cilindra un stūra testus ieteicams veikt pārmaiņus, kā arī ne pārāk bieži. Pētījuma sākumā ieteicams veikt pirms operācijas griešanās preferences novērtēšanu. Precīzākai novērtēšanai ieteicams…
Sulfonamide moiety as "molecular chimera" in the design of new drugs.
2021
Background: The -SO2NH- group is of great significance in modern pharmaceutical use since, in sulfa-drugs, it is possible to introduce easily chemical modifications, and even small changes may lead to an improved version of an already existing drug. Objective: This paper aims to describe updated information in the sulfonamide field with a particular focus on new mechanisms of action, especially if discovered by employing computational approaches. Methods: Research articles that focused on the use of the sulfonamide moiety for the design, synthesis, and in vitro/in vivo tests of various diseases were collected from various search engines like PubMed, Science Direct, Google Scholar, and Scop…

Wybrane problemy zrównoważonej intensyfikacji rolnictwa na przykładzie badań w województwie opolskim
2017
Celem opracowania jest identyfikacja problemów związanych z wdrażaniem w gospodarstwach rolnych województwa opolskiego strategii zrównoważonej intensyfikacji. Materiał pierwotny do badań zebrano w 2014 roku metodą wywiadu kwestionariuszowego w 100 celowo dobranych gospodarstwach rolnych o powierzchni powyżej 10 ha UR w subregionach reprezentatywnych dla rolnictwa regionu. Na podstawie badań stwierdzono, że rolnicy najczęściej wybierają trajektorię rozwojową, polegającą na powiększaniu areału posiadanej ziemi, przy jednoczesnym dostarczaniu dodatkowych usług środowiskowych. W opinii badanych rolników regulowana normami środowiskowymi intensyfikacja produkcji rodzi potrzebę ciągłego uczenia s…
Measuring Socio-Economic Welfare and Sustainable Transport – Selected Dilemmas
2017
The aim of this paper is to present and elaborate relations between the understanding and main indicators of socio-economic welfare, including indicators of sustainable development, and the measurement methods of sustainable transport. The focus is on the role that transport basically plays for nearly all dimensions of living conditions and the quality of life. First, the defi nition of socio-economic welfare and different views on measuring welfare are presented. Then, the meaning of transport for improving socio-economic aspects of life, as well as the need for sustainable transport are underlined. In the last part of the article developed indicators of sustainable transport are discussed…
Biomass estimator for NIR image with a few additional spectral band images taken from light UAS
2012
A novel way to produce biomass estimation will offer possibilities for precision farming. Fertilizer prediction maps can be made based on accurate biomass estimation generated by a novel biomass estimator. By using this knowledge, a variable rate amount of fertilizers can be applied during the growing season. The innovation consists of light UAS, a high spatial resolution camera, and VTT's novel spectral camera. A few properly selected spectral wavelengths with NIR images and point clouds extracted by automatic image matching have been used in the estimation. The spectral wavelengths were chosen from green, red, and NIR channels.
Depth perception in tablet-based augmented reality at medium- and far-field distances
2013
Current augmented reality (AR) systems often fail to indicate the distance between the user and points of interest in the environment. Empirical evaluations of human depth perception in AR settings compared to real world settings are needed. Our goal in this study was to understand tablet-based AR depth perception by comparing it with real-world depth perception.
The regionalization of national input-output tables : A study of South Korean regions
2018
This paper uses survey‐based data for 16 South Korean regions to refine the application of Flegg's location quotient (FLQ) and its variant, the sector‐specific FLQ (SFLQ). These regions vary markedly in terms of size. Especial attention is paid to the problem of choosing appropriate values for the unknown parameter δ in these formulae. Alternative approaches to this problem are evaluated and tested. Our paper adds to earlier research that aims to find a cost‐effective way of adapting national coefficients, so as to produce a satisfactory initial set of regional input coefficients for regions where survey‐based data are unavailable. Este documento utiliza datos basados en encuestas de 16 reg…
