Czechoslovak productive efficiency of the iron and steel sector fluctuated below the energy efficiency frontier. Until early 1970s, the country's iron sector was one of the least efficient ones in our sample. It was, however, during the decades of 1970s and 1980s that efficiency measures were adopted and the energy efficiency of the Czechoslovak iron and steel sector increased significantly to, de

The differences in fuel consumption and exhaust emissions for residential areas with different street network designs were investigated. Five areas with three different designs, including a traditional grid network and designs feeding the traffic in from a surrounding street and from a centrally located street, were considered. Differences in total fuel consumption and amount of exhaust emissions

Normal ageing in men is associated with a physiological decline in testosterone levels, but adverse environmental or psychosocial factors may also impair testosterone secretion and cause secondary biological changes. In a number of observational or experimental studies in both animals and man, it has been possible to study the influences on gonadal function of stressful life situations. To underst

A mu-ISLM (micro Immuno Supported Liquid Membrane) extraction system coupled in a sequential injection analysis (SIA) configuration, capable of simultaneous sample cleanup and enrichment was developed. The capacity of the extraction channels - donor and acceptor, respectively - were reduced from originally 10 to 1.65 mu L. The acceptor channel surface was covered with a gold layer enabling immobil

Popular Abstract in Swedish Syftet med denna undersökning är att diskutera inlärares signaler om hjälp att uttrycka sig på främmande språk, här franska, signaler som här kallas ?sollicitationer?. Undersökningen handlar om vilken roll dessa spelar för den fortsatta utvecklingen av samtalet med den infödde talaren, närmare bestämt för att utlösa s.k. SPA (Séquences Potentiellement Acquisitionnelles)The aim of this study is to discuss how ?soliciting? (non-native speakers? requests of native speakers for help in how to express themselves in a foreign language) may play a part in the triggering of SPAs (Séquences Potentiellement Acquisitionnelles or ?learning?teaching sequences?). The beneficial effect of SPAs for learning is still controversial, since no correlation has yet been shown between

A modern gas turbine compressor, with its highly aerodynamically loaded blades, is sensitive to changes in profile shape and to surface roughness. Fouling is inevitable, despite highly efficient filtration systems. The remedy to this problem is washing. There are two different approaches, online or off-line washing. The off-line wash is the most effective one, whilst on-line washing only prolongs

We have recently reported that the inner layers of the arteries, the intima-media complex, of common carotid artery, move as much in the longitudinal direction as in the radial direction, during the cardiac cycle. In order to study this phenomenon we have developed a high-resolution ultrasonic method that can simultaneously record both the longitudinal and the radial movements of the arterial wall

This study investigates the establishment of alternative cell fates during embryoid body differentiation when ES cells diverge into two epithelia simulating the pre-gastrulation endoderm and ectoderm. We report that endoderm differentiation and endoderm-specitic gene expression, such as expression of laminin 1 subunits, is controlled by GATA6 induced by FGF. Subsequently, differentiation of the no

Several immunodeficiency-related genes are known and a numb er of disease causing mutations have been identified. Immunodeficiency related mutation information have been collected into IDbases. We are currently maintaining 15 registries, which are available at http://www.uta.fi/imt/bioinfo/. The databases are available for the following disorders: adenosine deaminase, CD3 epsilon, CD3 gamma, JAK3,

This thesis investigates the dynamics between firms’ shifting motives for engaging in foreign direct investments (FDIs) and the experiential knowledge acquired from increased experience and establishment in foreign markets. An embedded case study was performed on the multinational company Duni Group, drawing upon insights from semi-structured interviews with representatives from the case company.

Youth delinquency is an international phenomenon that has an impact on different aspects of society. This study aimed to understand how social workers describe the causes of youth delinquency and their reflections on how they conduct the preventative work at social services. The chosen method was semi-structured interviews with six social workers in Skåne, all with a minimum of one year of working

Aim of the studyRates of bystander CPR are increasing, yet mortality after out-of-hospital cardiac arrest (OHCA) remains high. The aim of this survey was to explore public knowledge and attitudes to CPR. Our hypotheses were that recent CPR training (< 5 years) would be associated with a high-quality response in a case vignette of OHCA with agonal breathing, and associated with an interest to becom

BackgroundSepsis is a common indication for admission to the intensive care unit (ICU). Since definitions vary across studies, comparisons of prevalence and outcomes have been challenging. We aimed to compare sepsis according to ICU discharge codes with sepsis according to Sepsis‐3 criteria and to investigate the epidemiology of sepsis in the ICU. We hypothesized that sepsis using discharge codes
