Performance analysis of Latvian zenith camera

2018

Since finalizing of design in 2016, the digital zenith camera of the University of Latvia was involved in a number of test observations as well as field observations at about 70 different sites. The paper presents analysis of observation results, estimation of instrument’s performance and accuracy. Random and systematic error sources are outlined. Impact of anomalous refraction on vertical deflection determination is discussed. Results of adaptation of GAIA reference star catalog for astrometric data reduction are reported.

5 – 6 gadus vecu bērnu pamatkustību pilnveidošana veselības un fiziskās aktivitātes mācības jomā

2022

Bakalaura darba temats: “ 5 – 6 gadus vecu bērnu pamatkustību pilnveidošana veselības un fiziskās aktivitātes mācības jomā”. Darba autors: Santa Muižniece Darba mērķis ir teorētiski izzināt un praktiski pētīt 5 – 6 gadus vecu bērnu pamatkustību apguves pilnveidošanu.. Teorētiskajā daļā analizēta bērnu pamatkustību pilnveidošanas iespējas dažādās šķēršļu joslās un kustību rotaļās. Empīriskā pētījuma laikā tika veidotas dažādas šķēršļu joslas un piedāvātas kustību rotaļas ar mērķi pilnveidot izvirzītos pamatkustību veidus. Pētījumā iesaistītajiem bērniem tika pilnveidoti vecumposmam apgūstamie pamatkustību veidi, kas apstiprina hipotēzi, ka veiksmīgāka pamatkustību apguve vecākajā pirmsskolas…

Assessing the conservation priority of freshwater lake sites based on taxonomic, functional and environmental uniqueness

2022

Aim We propose a novel approach that considers taxonomic uniqueness, functional uniqueness and environmental uniqueness and show how it can be used in guiding conservation planning. We illustrate the approach using data for lake biota and environment. Location Lake Puruvesi, Finland. Methods We sampled macrophytes and macroinvertebrates from the same 18 littoral sites. By adapting the original “ecological uniqueness” approach, we used distance-based methods to calculate measures of taxonomic (LCBD–t), functional (LCBD–f) and environmental (LCEH) uniqueness for each site. We also considered the numbers and locations of the sites needed to protect up to 70% of total variation in taxonomic, fu…

Effects of progressive aquatic resistance training on symptoms and quality of life in women with knee osteoarthritis: A secondary analysis.

2020

Abstract Objective: To conduct a secondary analysis to study the effects, those 4 months of aquatic resistance training have on self‐assessed symptoms and quality of life in post‐menopausal women with mild knee osteoarthritis (OA), after the intervention and after a 12‐month follow‐up period. Methods: A total of 87 post‐menopausal volunteer women, aged 60‐68 years, with mild knee OA were recruited in a randomized, controlled, 4‐month aquatic training trial (RCT) and randomly assigned to an intervention (n = 43) and a control (n = 44) group. The intervention group participated in 48 supervised aquatic resistance training sessions over 4 months while the control group maintained their usual l…

ANALISI DELLE TENSIONI RESIDUE NEL VETRO MEDIANTE LA FOTOELASTICITÀ CON FRANGE DI RIFERIMENTO

2011

L’analisi delle tensioni residue nei vetri viene di solito effettuata con metodi fotoelastici dato che il vetro è un materiale birifrangente. Questa memoria considera l’automazione del cosiddetto "test fringes” metodo che si basa sull’impiego di un compensatore di Babinet o di un provino inflesso. In particolare si propongono due metodi automatici basati sull’impiego del metodo del centro frangia in luce monocromatica e sull’impiego della fotoelasticità RGB in luce bianca. I metodi proposti possono efficacemente sostituire i metodi manuali.

Pannelli traslucidi preassemblati “a secco” e precompressi realizzati con vetromattoni “modificati”

2011

L’articolo illustra le problematiche connesse al progetto di un pannello preassemblato a secco e precompresso realizzato impiegando vetromattoni “modificati”, energeticamente efficienti. Tra le 21 nuove configurazioni del vetromattone individuate è stata indagata per via analitico-sperimentale quella più efficiente dal punto di vista energetico, al fine di valutarne la resistenza meccanica e conoscere lo stato deformativo che si genera nel giunto adesivo tra conchiglie di vetro e “cintura termica”.Per realizzare un taglio termico tra le due conchiglie di vetro e consentire l’inserimento di una o più lastre all’interno dell’intercapedine del vetromattone è stata, infatti, progettata una “cin…
