Sediment quality of the ecoregion Engure, Gulf of Riga, assessed by using ecotoxicity tests and biomarker responses

2014

Pētījuma mērķis bija novērtēt Engures ekoreģiona (Rīgas līča rietumu piekrastes) sedimentu kvalitāti, izmantojot sedimentu ekotoksicitātes testus. Lai noteiktu bioloģiskās atbildes reakcijas uz dažāda veida stresoriem, kā testorganismi pielietotas sānpeldes Monoporeia affinis and Pontogammarus robustoides, un izvēlēti biomarķieri (AChE, GST, GR, CAT, MT), kas noteikti gliemenēs Macoma balthica. Engures ekoreģionu varētu uzskatīt par nepiesārņotu rajonu, jo tā sedimentus raksturo salīdzinoši zemas smago metālu koncentrācijas. Engures ekoreģiona sedimentu ekotoksicitātes testu rezultāti neuzrādīja statistiski būtisku (>20% mirstība) toksisko efektu. Testorganismu izdzīvotība bija robežās no 8…

Rétro-observation des processus de décrue glaciaire à partir de peintures. Apports de la mono-photogrammétrie

2019

Alpine landscapes are indicators of climatic variations recognized through their geomorphological and glacial dynamics. Inthis field, the old documents (photographs, engravings, paintings…) constitute important data sources, used for the purposesof retro-observations. The classical methods consist, most often, to exploit them in descriptive works then being the subject ofnaturalistic cartographic retranscriptions. Today the contribution of innovative methods of treatment, such as mono-photogrammetry,offer new perspectives. It is thus possible to extract quantitative information from qualitative archives. This approachallows, in addition to a conventional landscape analysis, to project the i…

Curiosity and exploration: A conceptual overview and structural modeling

2001

Many attempts have been made to measure curiosity or intrinsic motivation. However, there is no consensus on what curiosity is. In the present study, five previously constructed curiosity inventories were translated to Finnish and modified to be convenient for fifth-graders. The main purpose of the study was to clarify the concept of curiosity. Using conceptual analysis and the results of previous studies, it was possible to construct nine alternative conceptual models of curiosity. The corresponding statistical models were expected to account for the covariances among 15 subscales measuring curiosity-related exploratory behavior. However, before proceeding to the subscale level, the struct…

Tempting to Tag : An Experimental Comparison of Four Tagging Input Mechanisms

2010

Tagging helps achieve improved indexing and recommendation of resources (e.g., videos or pictures) in large data collections. In order to reap the benefits of tagging, people must be persuaded to label the resources they consume. This paper reports on a study in which four different tagging input mechanisms and their effect on users’ motivation to tag were compared. The mechanisms consisted of a standard tag input box, a chatbot-like environment, a bookmarking mechanism, and a “tag and vote” game. The results of our experiment show that the use of the nonstandard tagging input mechanisms does not affect users’ motivation to tag. In some instances tagging mechanisms were found to distract us…

Sustainability Development in Mathematics Education : A Case Study of What Kind of Meanings Do Prospective Class Teachers Find for the Mathematical S…

2019

In this article, our focus is on sustainable development in mathematics education from the point of view of teacher training. The aim was to develop prospective teachers’ content knowledge and pedagogical content knowledge of school mathematics. As a case study, we chose the mathematical symbol “a/b”, and examined how prospective class teachers in Finland connect it to the concepts of fraction, ratio, division, rational number or probability. Mathematics textbooks often have a central role in lessons, and they affect strongly how pupils understand concepts and the relationships between them. We chose languaging as a multi-semiotic approach to interpreting what kind of meanings the prospecti…

La formalisation fractale des tissus urbains

1998

The article concerns the fractal approach as it can bring new results making more understandable the morphology of agglomerate urban patterns. A new paradigm is developed, in order to improve the study of urban organizations according to optimization criteria. Specific fractal and multifractal methods are explicitated and applied to the knowledge of some big metropolitan areas and towns in Franche-Comté (France).

Hip viscosupplementation under ultra-sound guidance riduces NSAID consumption in symptomatic hip osteoarthritis patients in a long follow-up. Data fr…

2011

Introduction: Non-steroidal anti-inflammatory drugs (NSAIDs) consumption is strictly related to a high gastrointestinal and cardiovascular mortality and morbidity rate. Osteoarthritis Research Society International (OARSI) recommendations in patients with symptomatic hip or knee OA stated that NSAIDs should be used at the lowest effective dose but their long-term use should be avoided if possible. OARSI guidelines for the treatment of the hip OA include the use of viscosupplementation, which aims to restore physiological and rheological features of the synovial fluid. Objective: Aim of this multicentric, open and retrospective study is to investigate if NSAID consumption may be reduced by t…
