The influence of gender, age, residential area, and socioeconomic status on the blood and serum levels of 13 trace elements was studied in boys and girls living in two Swedish cities with different socioeconomic and environmental characters. The same groups of adolescents were sampled twice, at ages 15 (n = 372) and 17 (n = 294) years. All the investigated factors were shown to be of importance. A
Genomewide linkage analysis has been extremely successful at identification of the genetic variation underlying single-gene disorders. However, linkage analysis has been less successful for common human diseases and other complex traits in which multiple genetic and environmental factors interact to influence disease risk. We hypothesized that a highly heritable complex trait, in which the contrib
Variations in molybdenum isotopic composition, spanning the range of similar to 2.3 parts per thousand in the terms of Mo-97/Mo-95 ratio, have been measured in sediment cores from three lakes in northern Sweden and north-western Russia. These variations have been produced by both isotopically variable input of Mo into the lakes due to Mo isotopic heterogeneity of bedrock in the drainage basins and
We investigated the smooth muscle contraction in response to noradrenaline (NA), endothelin-1 (ET) and 5-hydroxytryptamine (5-HT) in the omental artery and vein segments from a 67-year-old woman with idiopathic orthostatic hypotension. The blood vessels were obtained during the abdominal surgery and investigated in vitro. Noradrenaline, endothelin-1 and 5-hydroxytryptamine all induced a contractio
Objective: No method has yet been established to summarise different objective indicators of social outcomes into one score. The study aimed to develop and test a simple, brief and meaningful index of social outcomes that can be used across a broad range of mental health studies and is potentially obtainable from routine documentation. Method: An index capturing employment, accommodation and livin
Sex pheromones are the hallmark of reproductive behavior in moths. Mature females perform the task of mate signaling and release bouquets of odors that attract conspecific males at long range. The pheromone chemistry follows a relatively minimal design but still the combinatorial action of a handful of specialized pheromone production enzymes has resulted in remarkably diverse sexual signals that
Preface: This report has been produced in order to celebrate the 60th anniversary of professor Lars Erik Nevander on the 11th of November, 1981. A number of topics are presented within the field of building physics. They relate to heat transfer in buildings, air infiltration, moisture darnages etc, varying from energy conservation aspects to failures of the building and its design for moisture pro
In this Letter we describe a new method to combine the methods of matrix inversion and order-of-scattering to solve the light scattering of aggregates of arbitrary spheres by extending Mie theory, which is more expedient for calculations of the local field in both outside and inside of the spheres.

Uninformed buyers' demand for statistical screening between privately informed sellers is studied in a fixed price market. A single buyer will screen more extensively than would two or more buyers, since in the latter case buyers realize that sellers will be attracted to buyers with the most favorable screening policy (i.e., not to screen at all). This result is robust to some but not all types of
So-called child neuropsychiatric disorders (ADHD/DAMP, autism spectrum disorders, Tourette's syndrome) are being recognized with increasing frequency in child and adolescent psychiatry. Through follow-up studies, case reports and autobiographical accounts it has become evident that these disorders often persist into adulthood, and the need for diagnostic evaluation of adults is increasing. The Neu
Objective To explore fetal ductus venosus (DV) flow velocity changes relative to umbilical artery (UA) blood flow and brain-sparing flow (BSF) during uterine contractions. Methods Forty-five term fetuses suspected of having growth restriction were exposed to an oxytocin challenge test (OCT) with simultaneous Doppler velocimetry in the UA, middle cerebral artery (MCA) and DV. Basal BSF was defined
Popular Abstract in Swedish Denna avhandling i socialantropologi ägnas åt analysen av sociala och kulturella processer i Visaginassamhället efter sovjettiden. Visaginas (tidigare Sniechkus) byggdes under sovjettiden, åren 1975-1989, som hemvist för personal vid Ignalinas kärnkraftverk och deras familjer. De flesta invånarna i staden är ryssar som kom till Litauen mellan 1975 och 1989 för att byggaThis thesis focused on an examination of human agency and strategies for responding to rapid social and economic change. Fieldwork was carried out in the community of Visaginas town that was built during the Soviet period in Lithuania. The town is situated next to the Ignalina nuclear power plant. The majority of the town's inhabitants are Russians who immigrated to Lithuania from other areas of t
OBJECTIVES: The referrals of elderly for cardiac surgery are increasing. The aim of this retrospective study is to review the long-term survival and to identify causes of late death in elderly after cardiac surgery. DESIGN: Between 1990 and 1993, 130 octogenarians underwent cardiac surgery in our department. A majority (88%) had elective surgery. One hundred and nine patients (84%) were in New Yor
Popular Abstract in Swedish Många material som ingår i tillverkade varor har kvar sina kvaliteter även när varorna är uttjänta. Men bara en liten del av dessa material återvinns idag på ett sätt som gör det möjligt att återanvända materialet för samma syfte och med bevarade egenskaper. I allmänhet har det industriella samhället fortsatt att praktisera en slit- och slängmentalitet, trots att det beMany anthropogenically-produced or beneficiated materials contained in “end-of-life” products retain a great proportion of the invested manufacturing work when discarded. Very few such materials are reconstituted and applied in new products at the same material inherent quality level as in their first lifetime – a process known as “closed-loop recycling”. In general, industrial society maintains a
In this article, the author discusses the implications of a 6+6-hour model for the production economy of the Finnish Company Essilor Oy. The theory of returns to scale has been used to analyse the results of the change from one 8-hour shift to the 6+6-hour-shift system. It is shown that the company Essilor attained a better production economy and increased profit by introducing a 6+6-hour-shift sy
