Single Event Transients and Pulse Quenching Effects in Bandgap Reference Topologies for Space Applications
2016
An architectural performance comparison of bandgap voltage reference variants, designed in a $0.18~\mu \text {m}$ CMOS process, is performed with respect to single event transients. These are commonly induced in microelectronics in the space radiation environment. Heavy ion tests (Silicon, Krypton, Xenon) are used to explore the analog single-event transients and have revealed pulse quenching mechanisms in analogue circuits. The different topologies are compared, in terms of cross-section, pulse duration and pulse amplitude. The measured results, and the explanations behind the findings, reveal important guidelines for designing analog integrated circuits, which are intended for space appli…
How do gender, Internet activity and learning beliefs predict sixth-grade students’ self-efficacy beliefs in and attitudes towards online inquiry?
2021
Today’s students search, evaluate and actively use Web information in their school assignments, that is, they conduct an online inquiry. This current survey study addresses sixth-grade students’ self-efficacy beliefs in and attitudes towards online inquiry, and to what extent free-time and school-related Internet activity, gender and learning beliefs explain these. The questionnaire was administered in 10 schools to 340 sixth-graders in Finland. Exploratory and confirmatory factor analyses revealed three elements of self-efficacy beliefs: self-efficacy in Web searching, the evaluation of sources and synthesising information. Furthermore, attitudes towards online inquiry loaded into two fact…
Il pagamento al creditore apparente nella prospettiva di un diritto europeo dell'obbligazione
2009
Il saggio analizza l’istituto del pagamento al creditore apparente e ne offre una rilettura in chiave di modi di estinzione dell’obbligazione diverso dell’inadempimento fondato sulla rottura del nesso di correlazione tra debito e credito. Lo studio del pagamento al creditore apparente offre, inoltre, una decisiva conferma della nozione di obbligazione come rapporto giuridico al cui interno trovano la sintesi due situazioni giuridiche dal contenuto diverso: il debito e il credito. La diversità di contenuto di debito e credito rappresenta la più significativa caratteristica dell’obbligazione e fa segnare la distanza dalla nozione tradizionale di obbligazione connotata invece dalla specularità…
The assessment of skeletal status in young patients with Turner syndrome by 2 densitometric techniques: Phalangeal quantitative ultrasound and dual e…
2018
Background. Studies using dual energy X-ray absorptiometry (DXA) demonstrate a reduction in bone mineral density (BMD) in children and adolescents with Turner syndrome (TS). However, these studies do not take into account changes in bone size, which influence BMD in the case of short-statured patients. Phalangeal quantitative ultrasound (phQUS) measurements have shown an ability to reveal changes due to skeletal growth, aging, and bone and mineral disorders. There is limited data on bone mineral status in girls with TS assessed by 2 different techniques, i.e., DXA and phQUS. Objectives. The aim of this study was to investigate the potential negative impact of TS on bone status and to assess…
Netaisnas iedzīvošanās institūta regulējums Civillikumā, tā salīdzinājums ar kopējā modeļa projektu (draft common frame of reference)
2017
Par netaisnu iedzīvošanos pēc neatkarības atjaunošanas Latvijā rakstīts ārkārtīgi maz. Izsmeļošākais avots ir Civillikuma saistību tiesību daļas komentāri, kuri gan arī sastādīti pirms vairāk nekā 16 gadiem. Tiesu prakse gan rāda, ka strīdi no netaisnas iedzīvošanās izceļas pietiekami bieži, tomēr šobrīd likumā atrodamā sistēma ir arhaiska, smagnēja un sadrumstalota. Eiropā ir izstrādāts Kopējā modeļa projekts (Draft Common Frame of Reference), kurš netaisnas iedzīvošanās regulējumam veltījis atsevišķu grāmatu. Darbā autore analizē netaisnas iedzīvošanās sistēmu Civillikumā un meklē efektīvāko regulējumu šim institūtam, salīdzinot to ar Kopējā modeļa izstrādāto netaisnas iedzīvošanās sistēm…
La selección de las noticias en el entorno de un centro de documentación de información de actualidad
2002
In information retrieval systems operation, lack of adequate selection criteria originates information overload and has negative consequences in relevance judgments. In the context of a news reference service, three leveis in the selection process are proposed. The first one relates to the type of sources covered by the system, the second set of criteria determines which publications are included in the process of document analysis. The last one applies to the selection of individual documents based on their informative content. La falta de criterios idóneos de selección puede provocar un grave problema de saturación informativa, lo que repercute negativamente en la búsqueda posterior de in…
Person reference as a device for constructing experiences as typical in group therapy.
2008
Sharing one's experiences is a crucial activity in group therapies. In such therapies, groups can be either constituted around one problem or goal common to all the clients, or the group can work as a place in which clients can learn from one another and share experiences whether their individual problems are similar or not. Almost all (psycho) therapy types have a group application, and groups are assumed to be rather efficient in psychological progressing (see, e.g. Corey, 1986; Wootton, 1977). In this article I will concentrate on one type of group therapy, namely the Minnesota model group therapy for addicts, and examine how the clients share experiences and, especially, how they constr…
Economics of wage premia and wage rigidity
2017
The focus of this dissertation is on the effects of specific employer characteristics on wages and wage rigidity and how these characteristics enter the wage-setting process. The dissertation includes an introductory chapter and five separate essays. The introduction provides motivation, background on the main keywords and an overview of the thesis. Chapters two and three study how internal references affect wages and wage rigidity from a theoretical perspective. The fourth chapter estimates the effect of firm size on wages in the Finnish labor market. Chapter five develops on the preceding and analyses how profit sharing schemes affect the firm size premium. Chapter six studies how interna…
Clinical assessment and comparison of ACL reconstruction using synthetic graft (Neoligaments versus FiberTape).
2021
Background Due to the low potential for primary biological healing of the anterior cruciate ligament (ACL), the most popular approach is currently reconstruction using a graft. Recent research indicates that the technique of strengthening a damaged ligament with synthetic tapes (internal bracing) may be an alternative to reconstructive treatment, especially in cases of partial ACL damage. Objectives To compare and evaluate the possibility of using a synthetic graft (Neoligaments or FiberTape) to treat partial lesions of the ACL. Material and methods This was a retrospective cohort study. Selected from a pool of 128 patients undergoing primary unilateral intra-articular ACL reconstruction du…
La cohesió léxica en seqüències narratives.
2008
Aquesta tesi doctoral s'ocupa de les operacions discursivocognitivesd'establiment de referents i de represa lèxica de la referència en textos escritsd'estudiants de secundària.Partim d'un corpus doble constituït per seqüències narratives produïdes, d'unabanda, per alumnes de quart curs d'E.S.O (aprenents) i, d'altra banda, per periodistescinematogràfics (experts), que ens proporcionen el corpus de control i, doncs, la base decomparació de les produccions dels aprenents.En primer lloc, hem analitzat els diversos tipus d'estructures nominals ipredicatives que vehiculen la introducció dels referents discursius. En segon lloc, enshem ocupat de la represa lèxica dels referents mitjançant la repe…
