Analysing ocean wave data for improved planning of future offshore renewable energy
No full textClimate change is impacting people, industries and economies to ever greater degrees. One of the rapidly growing industries impacted by climate change is offshore wind energy. Numerous studies have shown a wide range of climate change impacts on the offshore wind resource. However, other potential impacts of climate change are less understood. This thesis investigated climate change impacts on installation and maintenance of offshore wind farms. Installation and maintenance each account for 20-25% of offshore wind farm lifecycle costs, and these activities significantly depend on ocean wave conditions. Wave reanalysis datasets, like ERA5, are often used to assess long-term wave climate. This thesis assessed the accuracy of the ERA5 wave dataset as a source of global ground-truth significant wave height data. The author showed that ERA5 tends to underestimate significant wave height above 5 m. The ERA5 accuracy increases with the increasing distance to shore, and is higher in more recent years. These findings informed the use of the ERA5 wave data in combination with atmospheric data from eight CMIP6 climate models to train a neural network to produce wave climate projections. The large size of the dataset, which included global 3-hour data for five variables (including significant wave height), hindered learning of the feed-forward neural network. Since the neural network failed to produce acceptable wave climate projections, an ensemble of existing numerical projections was used to quantify impacts of climate change on accessibility - the fraction of time when the weather does not impede installation and maintenance of offshore structures. This ensemble consisted of 11 wave simulations from the COWCLIP project, where wave models were forced with atmospheric data from seven CMIP5 climate models. This study found that accessibility is projected to increase in the North Atlantic and Asia, but decrease in Central America and in some cases in Australia and on the western North American coast. Most of the accessibility increase in the North Atlantic comes in the winter months, suggesting lengthening of the traditional maintenance season

Conflicting patterns of thought in the Russian debate on transition: 2003-2007
No full textThis article is a continuation of two essays by the same author on Soviet/Russian economic debates between 1987 and 2002 published in Europe-Asia Studies in 2006 and 2007, so now the series of articles covers 20 years of Soviet/Russian discussions on economic reforms. Should Russia strive to become a 'Western' country marked by democracy and a market economy serving the individual interests of its citizens, or was it more important to become a great power again? Are Western patterns of political and economic life suitable for Russia or is the attempt to import foreign institutional structures doomed for failure, making it necessary for Russia to find her own way? This type of question, going far beyond the realm of economics, was and still is at the heart of the debate among Russian economists, which shall be discussed here, on the basis of a qualitative content analysis of the most important economic journals and selected monographs. --
Scythian blade weapon in the studies of archaeologists of kyiv scientific school
No full textThe article discusses the history of studies of Scythian swords and daggers by the researchers of Kyiv
scientific school. The author critically analyzes the main theories referring to the general and particular
questions of blade weapon research.
The paper considers the questions of the origin and distribution and examines the problems of their
usage in battles and in rituals. The question of the Scythian sword origin there are three main hypothesis
outlined: Near East theory (by M. Rostovtsev and A. Meliukova), Central Asia theory (A. Terenozhkin,
V. Murzin, V. Klochko), and North Caucasus theory (O. Lieskov, Ye. Chernenko, S. Skoryi, S. Makhortykh,
Yu. Boltryk). The third version is considered as most common and scientifically grounded.
The ritual function of swords an daggers was analyzed by S. Bessonova in the context of research of the
Scythian religion. A philosophical search has a prominent place in the articles by Yu. Boltryk. Theoretical
studies of military affairs were conducted by E. Chernenko and S. Skoryi.
Since the beginning of the 21st century, researchers pay more attention to the interpretation of chance
finds. S. Skoryi joins the debate about the Scythian routs to the Central Europe. Distribution of swords and
daggers in the Black Sea region were analyzed by Yu. Boltryk.
The general perspective shows the concept of studying weapon as a social and ethnic marker. Recently,
researchers are increasingly paying attention to the possible ethno-cultural specifics of the Scythian weapon.
The issue of social and ethnic interpretation were examined by S. Skoryi, D. Grechko and S. Makhortykh.
Today most investigators assume that the Scythian nomads were the main carriers of blade weapon in the
area of Eastern Europe Forest-Steppe.Статтю присвячено історії вивчення мечів та кинджалів скіфського часу дослідниками київ-

Hepatic real-world outcomes with obeticholic acid in primary biliary cholangitis (HEROES): a trial emulation study design
No full text\ua9 2024 The Author(s). Background and aims: Primary biliary cholangitis (PBC) is a rare, progressive liver disease. Obeticholic acid (OCA) received accelerated approval for treating patients with PBC in whom ursodeoxycholic acid (UDCA) failed, based on a surrogate endpoint of reduction in alkaline phosphatase. Analysis of the long-term safety extension with 2 external control groups demonstrated a significant increase in event-free survival in OCA-treated patients. This fully real-world evidence study assessed the effect of OCA treatment on the clinical outcomes. Approach and results: This trial emulation used data from the Komodo Healthcare Map™ claims database linked to US national laboratory, transplant, and death databases. Patients with compensated PBC and intolerance/inadequate response to UDCA who initiated OCA therapy were compared with patients who were OCA-eligible but not OCA-treated. The primary endpoint was time to first occurrence of death, liver transplant, or hospitalization for hepatic decompensation, analyzed using a propensity-score weighted Cox proportional hazards model. Baseline prognostic factors were balanced using standardized morbidity ratio weighting. For the primary analysis, 4174 patients contributed 11,246 control index dates; 403 patients contributed OCA indexes. Weighted groups were well balanced. Median (95% CI) follow-up in the OCA and non-OCA arms was 9.3 (8.4–10.6) months and 17.5 (16.2–18.6) months (weighted population; censored at discontinuation). Eight events occurred in the OCA arm, 32 in the weighted control (HR=0.37; 95% CI=0.14–0.75; p<0.001). Effects were consistent for each component of the composite endpoint. Conclusions: We identified a 63% reduced risk of hospitalization for hepatic decompensation, liver transplant, or death in OCA-treated versus non–OCA-treated individuals
Ergonomics of Protective Clothing Proceedings of NOKOBETEF 6 and 1st European Conference on Protective Clothing held in Stockholm, Sweden, May 7-10, 2000
No full textThe European Directives on personal protective devices have increased the interest in protective and functional properties of work clothing and intensified standardisation work as well as stimulated research in areas with limited knowledge. There is a long tradition of research and information exchange in the Nordic countries on the subject. The NOrdisk KOrdineringsgruppe om BEskyttelseskläder som TEknisk Forebyggelsesmiddel (Nordic Coordination Group on Protective Clothing as a Technical Preventive Measure) was founded in 1984. NOKOBETEF is an independent society of professionals from the Nordic as well as other countries. NOKOBETEF has since its foundation organised symposia in Copenhagen (1984), Stockholm (1986), Gausdal, Norway (1989), Kittilä, Finland (1992), and Elsinor, Denmark (1997). The conferences have long had a good attendance from European countries and from overseas. The 6th Nokobetef conference was organised as the 1st European Conference on Protective Clothing to emphasize the European dimension. During the conference the European Society for Protective Clothing was founded. One of its first tasks will be to prepare for the 2nd conference to be held in Switzerland in 2003. The proceedings of this conference cover a broad spectrum of the subject protective clothing. Emphasis was given to the ergonomics aspects, which is in line with the present interest and priorities of the European standardisation bodies (CEN). A functional and comfortable use of protective clothing is a key element for a succesful implementation of this kind of preventive and protective measures in the workplaces. A total of 77 papers are presented in this book. They represent a qualified source of new, valuable and useful information for the advancement of the knowledge and the application of protective clothing
