Popular Abstract in Swedish Glas kan användas för retrospektiva radon mätningar på grund av radondöttrars förmåga att implantera i glasets översta skikt. Mängden implanterad aktivitet blir lätt påverkad av en rad olika faktorer i den omgivande luften. Experimentella metoder har därför utvecklats för att bestämma djupfördelningen av alfarekyl-implanterat 210Po i glas. Detta göres genom gradvis etsnGlass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. In this work, experimental methods based on etching to determine the depth distribution of recoil-implanted 210Po in glass from radon decay in air were develo

In market-driven product development and release planning, it is important to market success to find the right balance among competing quality requirements. To address this issue, a conceptual model that incorporates quality as a dimension in addition to the cost and value dimensions used in prioritisation approaches for functional requirements has been developed. In this paper, we present an indu

After several years of disussions, tests, investigations and additional tests, the suppliers and retailers within the Swedish business sector for food and commodities formed a jointly owned, non-profit company in 1997, which subsequently started in physical operations in 2000. This company, Svenska Retursystem AB (www.retursystem.se), is now responsible for introducing returnable transport packagi

Vocal learning is a critical behavioral substrate for spoken human language. It is a rare trait found in three distantly related groups of birds-songbirds, hummingbirds, and parrots. These avian groups have remarkably similar systems of cerebral vocal nuclei for the control of learned vocalizations that are not found in their more closely related vocal non-learning relatives. These findings led to

Popular Abstract in Swedish Avinstitutionaliseringen av den psykiatriska vården har medfört att personer med funktionshinder p.g.a. en psykisk sjukdom numera huvudsakligen bor och erbjuds vård ute i samhället. I Sverige har få systematiska studier genomförts som undersöker livssituationen för individer med en allvarlig psykisk sjukdom som bor ute i samhället. Att drabbas av en sjukdom som schizofrThis 18-month follow-up study investigated needs for care and support, quality of life and social network in individuals with schizophrenia or a schizoaffective disorder living in the community and in contact with psychiatric services. The validity of Antonovsky's sense of coherence (SOC) measure was also examined. At baseline 120 patients were interviewed and 94 of these participated in the follo

Popular Abstract in Swedish Allteftersom kraven på kvalité och prestanda hos dagens produkter ökar används alltmer avancerade material som en del av modern produktion. Problemet som uppstår är dock att dessa material ställer nya krav på tillverkningsprocessen och då inte minst vid skärande bearbetning. Trots att en betydande mängd forskning redan har publicerats vad gäller skärande bearbetning av As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. Even though a significant amount of research has been published on the machining of these materials knowledge is still limited in several crucial areas. A problem w

Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean in the west, by Israel in the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing population.

Popular Abstract in Swedish Transplantation av nervvävnad till hjärnan är inte en ny idé. Redan 1890, publiserade Thompson de första försöken att transplantera vuxen hjärnvävnad till det vuxna centrala nervsystemet och han rapporterade att vävnaden överlevde i sju veckor "without wholly losing its identity". Trots detta var det först under 1970-talet som metoderna för intracerebral nervcellstranspIntracerebral neuronal transplantation have been shown to ameliorate symptoms of brain dysfunction in both animals models and Parkinson's disease, although problems still remain. The newly introduced technique of ex vivo gene transfer could serve as an alternative approach, possible avoiding some of the draw-backs of the embryonal tissue used in neuronal grafting. We have investigated the feasibli

Abnormalities within a limited number of small and medium enterprises (SMEs) in Australia are reported. A set of interrelated industrial issues are brought out in order to advance the state of knowledge and avoid similar abnormalities / irregularities and to bring back some ideas for the mitigations. Impacts on new automated systems and on industrial as well as safety standards are expected in the

During the last decades there has been an upsurge in research on xenophobic populist parties, mirroring their political successes. In the Swedish context, characterised by neoliberal restructuring, issues of race', citizenship and belonging have been important elements of the public debate. These issues have unfolded in parallel with the presence of a neo-Nazi social movement and the emergence of

Background: Selective dorsal rhizotomy (SDR) is a well accepted neurosurgical procedure performed for the relief of spasticity interfering with motor function in children with spastic cerebral palsy (CP). The goal is to improve function, but long-term outcome studies are rare. The aims of this study were to evaluate long-term functional outcomes, safety and side effects during five postoperative y

The purpose of this article is to present and discuss the development of a system for assessing and improving healthcare organisations. The system components comprise (1) a framework or model for assessing, measuring, diagnosing and improving healthcare organisations, (2) a simple methodology for data collection, data analysis and prioritising improvement areas and (3) an index named ILL (innovati

We describe a simple method to detect significant changes of the total ozone column from global (diffuse and direct) zenith sky measurements taken at the Earth’s surface. The calculation of the total ozone column relies on measured irradiance at two wavelengths in the ultra violet part of the solar spectrum. One of these (i.e. 306 nm) are appreciable absorbed by ozone whereas the other (i.e. 360 n

Diabetic retinopathy is an ophthalmic complication of diabetes that currently affects 93 million people worldwide. Diabetic macular edema is a subtype of diabetic retinopathy that is characterized by leaking blood vessels in the central part of the retina, and it is a major cause of vision loss in individuals with diabetes. Screening for retinopathy is performed at regular intervals to identify su

The best valve substitute for aortic valve replacement (AVR) in terms of hemodynamic performance, durability, incidence of complications, and survival remains the subject of much debate. It has been suggested that valve performance is influenced by the potentially modifiable variable prosthesis-patient mismatch (PPM). PPM has been reported to be detrimental for survival and symptom resolution main
