Weight Reduction Behaviors Among European Adolescents : Changes From 2001/2002 to 2017/2018
2020
Purpose The purpose of this study was to analyze changes in the prevalence of weight reduction behaviors (WRBs) among European adolescents from 26 countries between 2001/2002 and 2017/2018. The impact of the perception of body weight on WLB was also analyzed, with particular attention being paid to overestimation. Methods The data of 639,194 European adolescents aged 11, 13, and 15 years who participated in the Health Behaviour in School-aged Children survey were analyzed. Age-standardized prevalence rates of WRB were estimated separately by survey round and gender for each country, using the overall 2017/2018 Health Behaviour in School-aged Children study population as the standard. Multiv…
The effect of a failure and submaximal blood flow restriction resistance exercise protocol on changes in muscle size, strength and swelling
2016
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Introduction: Blood flow restricted resistance exercise (BFRRE) can induce rapid increases in muscle size, strength and swelling. No previous research has investigated the importance of conducting BFRRE to voluntary failure and few studies has been carried out to investigate associations between swelling and muscle size. Therefore, the aim of the present study was twofold (1) compare changes in muscle size and strength between a failure (FA) and submaximal (SU) BFRRE protocol (2) investigate associations between swelling and muscle size. Methods: Seventeen untrained men had their legs randomized to FA and SU protocols. The interv…

Enhancing news recommendation using a personalized content manager
2018
The surge in the amount of information available on the internet and the number of users utilizing such information poses new challenges for information systems. This rapid growth in information is palpable in the news provisioning domain where users spend time deciding which of the many channels provides news in a most reliable and useful fashion. In the last few years, News aggregation platforms are now present which reduces the time users spends in consuming news from multiple sources. But news provisioning is more than just aggregating and presenting news. It must also include taking into cognizance users’ needs. Therefore, recommendation algorithms are developed by information systems …
Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
Skābekļa patēriņa un sirdsdarbības frekvences salīdzinošs novērtējums jaunām, fiziski netrenētām sievietēm vienādas fiziskās jaudas testos uz slīdcel…
2018
Cilvēka fizisko darbaspēju novērtēšanai šobrīd ir pieejams visai plašs standartizētu slodzes testu klāsts. Testa izvēle ir atkarīga no testēšanas mērķa, tomēr nav viennozīmīgu kritēriju, kas ļautu izvēlēties labāko testu fizisko darbaspēju novērtēšanai. Savukārt, visbiežāk izmantojamie parametri fiziskās sagatavotības novērtēšanai funkcionālo testu laikā ir sirdsdarbības frekvence un skābekļa patēriņš. Darba mērķis bija salīdzinoši izvērtēt skābekļa patēriņa un sirdsdarbības frekvences izmaiņu dinamiku vienādas jaudas slodzē, slodzi veicot uz veloergometra un slīdceliņa. Pētījumā piedalījās 10 jaunas, fiziski netrenētas sievietes, kuras veica standartizētu 3-pakāpju slodzi un veloergometra …
Viral and cellular determinants of hepatitis C virus RNA replication in cell culture.
2003
Studies on the replication of hepatitis C virus (HCV) have been facilitated by the development of selectable subgenomic replicons replicating in the human hepatoma cell line Huh-7 at a surprisingly high level. Analysis of the replicon population in selected cells revealed the occurrence of cell culture-adaptive mutations that enhance RNA replication substantially. To gain a better understanding of HCV cell culture adaptation, we characterized conserved mutations identified by sequence analysis of 26 independent replicon cell clones for their effect on RNA replication. Mutations enhancing replication were found in nearly every nonstructural (NS) protein, and they could be subdivided into at …
BMW autovadītāju braukšanas ieradumi, vērtības un tēls citu marku autovadītāju uztverē
2017
Bakalaura darba mērķis ir noskaidrot četru dažādu automobiļu marku (BMW, Volkswagen, Aud un Mercedes) vadītājiem piemītošo braukšanas ieradumu un vērtību atšķirības, kā arī noskaidrot BMW markas vadītāju tēlu citu ceļu satiksmes dalībnieku uztverē. Par darba teorētisko pamatu var uzskatīt Šaloma H. Švarca universālo vērtību teoriju. Bakalaura darba ietvaros tiek veikta kvantitatīvā aptauja internetā, kā arī tiek izmantota kvalitatīvā metode – fokusgrupas intervija. Rezultāti liecina par to, ka BMW markas vadītāji ir vairāk tendēti uz agresīvu un riskantu braukšanu salīdzinot ar pārējām pētījumā iekļautajām grupām, savukārt, par vismierīgāko vadītāju grupu var uzskatīt Volkwagen markas vadīt…
