2019
Diplomdarbs ir uzrakstīts latviešu valodā uz 50 lapām. Tajā ir 10 attēli, 8 tabulas, un 33 atsauces uz literatūras avotiem. depresiju sastāda lielu daļu no psihiskajāmsaslimšanām. Eiropā saslimstība ar depresiju sastāda lielu daļu no psihiskajām saslimšanām. No SPKC informācijas, no visiem bērniem un jauniešiem Latvijā ar depresiju un saistītajām saslimšanām slimo tikai 0,2%, bet visā pasaulē šie procenti svārstās apmēram no četriem līdz astoņiem procentiem. Šādi dati liecina par to, ka Latvijā varētu būt nepilnvērtīgi dati par bērnu un jauniešu saslimstību ar depresiju. Pētījuma mērķis bija noskaidrot depresijas simptomu biežumu Latvijas skolu bērniem vidusskolas vecuma pētāmajā grupā, izm…
Efficient estimation of tuned liquid column damper inerter (TLCDI) parameters for seismic control of base‐isolated structures
2022
This paper presents an enhanced base-isolation (BI) system equipped with a novel passive control device composed of a tuned liquid damper and an inerter (TLCDI). With the aim of reducing the seismic response of BI systems, this contribution focuses on the design of the TLCDI providing analytical solutions for the optimal TLCDI parameters, easily implementable in the design phase. The effectiveness of the proposed approach in terms of seismic response reduction and computational gain is validated by comparison with classical numerical optimization techniques. The control performance of two different base-isolated TLCDI-controlled structures is assessed by employing real-ground motion records…

Glasgow ou l’Écosse urbaine dans les poèmes de Hugh MacDiarmid
2012
Hugh MacDiarmid is sometimes still thought a parochial poet, mostly interested in the depiction of rural Scotland. However, in the 1930s, he wrote several poems about the city of Glasgow but his work on urban predicaments has been largely forgotten. In his Glasgow sequence, MacDiarmid, along with many other writers in the 30s, redefines Scotland as an urban nation. Post-industrial Glasgow urges the whole country to ‘re-write’ itself and the canonical representation of rural Scotland to fade away. Scotland is mercilessly deconstructed in Glasgow 1938: Glasgow is no longer ‘a dear green place’, Scotland no longer a land of peasants but urban hell where filthy disease and dirty capitalism spre…
Early markers of language delay in children with and without family risk for dyslexia
2015
Accepted manuscript version. Published version at http://doi.org/10.1177/0142723715596122. This study examined the extent to which receptive and productive vocabulary between ages 12 and 18 months predicted language skills at age 24 months in children born with family risk for dyslexia (FR) and a control group born without that risk. The aim was to identify possible markers of early language delay. The authors monitored vocabulary growth in 32 FR children and 21 control children longitudinally by using the Norwegian adaption of the MacArthur–Bates Communicative Development Inventories. The results show different patterns in the two groups: the study found a stronger interdependence of early…
Stereoselective Synthesis and Cytoselective Toxicity of Monoterpene-Fused 2-Imino-1,3-thiazines
2014
Starting from pinane-, apopinane- and carane-based 1,3-amino alcohols obtained from monoterpene-based β-amino acids, a library of monoterpene-fused 2-imino-1,3-thiazines as main products and 2-thioxo-1,3-oxazines as side-products were prepared via two- or three-step syntheses. When thiourea adducts prepared from 1,3-amino alcohols and aryl isothiocyanates were reacted with CDI under mild conditions, O-imidazolylcarbonyl intermediates were isolated which could be transformed to the desired 1,3-thiazines under microwave conditions. 1,3-Thiazines and 2-thioxo-1,3-oxazine side-products could also be prepared in one-step reactions through the application of CDI and microwave irradiation. The rin…
Nontraditional configuration of tuned liquid column damper inerter for base-isolated structures
2023
In this paper, the concept of a novel passive control device, namely the Nontraditional Tuned Liquid Column Damper Inerter (NT-TLCDI), is investigated in combination with seismic base isolation (BI), to control lateral displacement demands in base-isolated structures during seismic events. The considered NT-TLCDI is a revision of the ordinary configuration of the recently proposed Tuned Liquid Column Damper Inerter (TLCDI). Unlike the traditional TLCDI layout, which involves a secondary liquid mass in a U-shaped tank coupled with a grounded inerter and connected to the isolation system by a spring-dashpot system, in the NT-TLCDI configuration, the damper is in parallel with the inerter rath…
The CDIO Syllabus 3.0 - An Updated Statement of Goals
2022
The CDIO Initiative is going through a process of reconsidering and updating the CDIO approach for engineering education development. Previous work resulted in substantial updates of the twelve CDIO standards and the introduction of “optional” CDIO standards. This paper reports on a similar review and update of the CDIO Syllabus to version 3.0. It has been developed by a working group consisting of four sub-groups and iterated and refined guided by feedback from the whole CDIO community. There are mainly three external drivers that 18 Proceedings of the 18th International CDIO Conference, hosted by Reykjavik University, Reykjavik Iceland, June 13-15, 2022. motivate the changes: sustainabili…
Anxiety and depression levels in prepubertal obese children: a case-control study
2014
Introduction Childhood obesity has become worldwide epidemic both in Western and in developing Countries and has been accompanied by many serious and severe comorbidities such as diabetes, hypertension, sleep apnea syndrome, depression, dyslipidemia, impaired glucose homeostasis, steatohepatitis, and intracranial hypertension, as well as medical concerns unique to youth such as accelerated pubertal and skeletal development and orthopedic disorders. To date no specific studies about the psychological assessment in pediatric obesity are present. Therefore, the aim of this study was to evaluate the putative relationship between psychological troubles and obesity in a sample of school-aged chil…
Problematics of Bonds in Hugh MacDiarmid's Poetry
2012
Hugh MacDiarmid is considered the most important Scottish poet of the 20th century. He is mostly celebrated for the Scots lyrics he wrote in the 1920s and his long poem A Drunk Man Looks at the Thistle, published in 1926. Because of their fragmentation, the poems of the Thirties, most of which were part of the unpublished project Mature Art, and In Memoriam James Joyce (1955), have not attracted the same critical attention. However, they represent the culmination of a very complex stylistic crisis that this study offers to analyse thanks to the question of bonds, especially problematic bonds. The poetry portrays humanity torn by social division, treason and death, but it deals with loss too…
