This paper gives an overview of the cadmium (Cd) situation in agricultural systems and human exposure in Sweden. Cadmium levels in agricultural soils (the plow layer) increase by 0.03% to 0.05% per year. Feed can give substantial contributions of Cd to local agricultural systems. Effects on human kidney function are indicated by some measurements already at today's exposure levels. If food product
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
Popular Abstract in Swedish Studiet av entreprenøren er ikke et studium om en «helt på sin hvite hest», som er en ikke uvanlig kritikk av vellykkete næringsdrivende, men snarere en analyse av helt vanlige menneskers tanker, drømmer og liv. Entreprenørene er vanskelige å finne for de er sjeldent forekommende i befolkningen. De er viktige fordi de utfører innovasjoner, som innebærer at man blir i stThis dissertation, which is an analysis of the entrepreneur at the micro level, supplements and underpins the understanding and use of the entrepreneur as an agent of social change in the analysis of economic change at the macro level. The aim of the thesis is firstly to seek out and identify businessmen of our time who claim to be innovative, and secondly to un-dertake a qualitative study and ana

New and innovative production equipment can be developed by introducing lightweight materials in modern day automotive industry production lines. The properties of these new materials are expected to result in improved ergonomics, energy savings, increased flexibility and more robust equipment, which in the end will result in enhanced productivity. Carbon composite materials are one such alternati
The concept of a ”green economy” is rapidly gaining interest around the world. However, the idea is not new. It appeared in 1989 in the book “Blueprint for a Green Economy”. During the 1990s and most of the 2000s, the green economy was not a widely used term. But it gained a new lease of life after the financial crisis of 2008 when governments and industries around the world needed to respond to e
The management of construction tolerances is a necessary and routine part of the construction activity and is normally brought to our attention only when failures are reported. In a study of tolerance management, the authors found widespread evidence of the same failures and the reasons for them. There seems to be no shortage of experience of the effects of failures in tolerances or of knowledge a
Urbanism is much more than simply an agglomeration of houses : it is a particular way of living space. Our considerations starts out from some of the historically prominent figures of urbanity, such as the market-place, the boulevard and the coffee house. Semiotics of space may either involve a certain number of elementary building-blocks being combined in particular ways, much as language is ; or
The declining trend in cardiovascular mortality rates seen since the mid-1970s in Western countries have been more pronounced for people in higher socioeconomic status (SES) groups. The fact that established risk factors, are limited in explaining the socioeconomic differences in cardiovascular disease (CVD) has opened new fields of research. One such field is the role of SES in the preclinical (a
