Incidence of dementia related to medical, psychological and social risk factors: A longitudinal cohort study during a 25-year period

This study is based on an entire cohort (n = 192) of 67-year-old persons born in 1902 and 1903 and living in a community in Southern Sweden. All subjects participated in interviews, psychological tests, and medical examinations. All contacts with primary health care and social services were recorded, as were death diagnoses. The cohort has been followed since 1969, with nine examinations until age

Trading Accuracy and Resource Usage in Highly Dynamic Vehicular Networks

Vehicular networks bring new ways of viewing road traffic management and safety applications. For the first time, it will be possible for vehicles to exchange information and build fine-grained knowledge about the current situation, estimating risks and adapting their driving. Central to these applications is the need to exchange information in a highly dynamic environment, building a view of the

Purchasing in power asymmetry - A study of vaccine procurement for developing countries

The purpose of this study was to increase the understanding of, and develop a model to explain, interrelations between purchasing strategies carried out by buyers within vaccine supply chains for developing countries and their buyer-supplier power structure. In the humanitarian aid context, availability of required goods (e.g. health related products) at the right time and place is of vital import

Dynamic Power System Load -Estimation of Parameters from Operational Data

The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. As a result of these disturbances new investigations have co

Programethos och dess betydelse för studenters lärande och personliga utveckling inom tekniska utbildningar

I Sverige, liksom i många västeuropeiska länder, satsas stora resurser och engagemang för att locka unga män och kvinnor att söka till tekniska utbildningar. Nya inriktningar och förändrade programtitlar skapas, utbildnings- och kursplaner skrivs om, marknadsföringen vässas och mottagande och stöd till studenterna utvecklas. Trots detta tycks det gå trögt. I denna artikel argumenterar vi för att d

Mellan provins och parnass : John Fernström i svenskt musikliv

The Swedish composer John Fernström (1897-1961) wrote over 200 pieces in the genres of symphonic music, chamber music and vocal music for mixed choirs, male choirs and solo vocals accompanied by piano. He lived most of his life in the province of Scania, first working in Helsingborg from 1916­ 1939 as a violinist in Nordvästra Skånes Orkester- förening [the Northwest Scanian Orchestra], whereafter

Improvement of the AMS-technique and applications to 3H and 59Ni Measurements

Popular Abstract in Swedish Utveckling av AMS-tekniken och tillämpningar på 3H och 59Ni mätningar Traditionellt mäter man radioaktivitet genom att registrera den utsända strålningen från sönderfallande kärnor. Denna sönderfallsmätning fungerar oftast bra så länge halveringstiden (den tid det tar för hälften av kärnorna att sönderfalla) är kort nog samt då man har tillräckligt mycket material. MetAccelerator mass spectrometry (AMS) is a highly sensitive technique for counting atoms. Its main advantage in comparison with radiometric methods is the smaller amount of sample required (by a factor of a thousand). The method has a high efficiency and requires only some ten mg of sample material. The radioisotope 59Ni is of great importance in nuclear waste management in the nuclear industry. Thi

Municipal Solid Waste Landfills in Jordan - Current Conditions and Prospective Future

Jordan has seen a large increase in population during the past five decades as a result of high population growth rate and forced migrations. Economical and cultural development has improved the standard of living and changed consumer habits in the community, resulting in an increase in the volume of Municipal solid waste (MSW) with time. World Bank visibility study (2004) showed that the rate of
