BACKGROUND: In health economics, health is regarded as part of an individual's human capital. As such it depreciates over time, and investments in health are made in order to keep the stock of health capital at the desired level. Using this framework for analysis of health-related behaviour and Swedish panel data, we examined whether the presence of asthma or allergy affects perceived health and i
54 human genes were selected as test targets for parallel cloning, expression, purification and crystallization. Proteins from these genes were selected to have a molecular weight of between 14 and 50 kDa, not to have a high percentage of hydrophobic residues (i.e. more likely to be soluble) and to have no known crystal structures and were not known to be subunits of heterocomplexes. Four proteins
A case-control study compared 129 men with earlier partial gastrectomy (operation during the period 1952-1961) with 216 men from a community-based population study. All were born 1910-1915 and the mean age was 72 years. Men with a previous partial gastrectomy had vertebral fractures in 19% compared with 4% (P < 0.01) in the control population. Bone mineral density (BMD) in the right calcaneus meas
This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. In the first case, part of the stillage stream after distillation was recycled and in th
This paper derives a generic model for the multiple-input multiple-output (MIMO) wireless channel. The model incorporates important effects, including i) interdependency of directions-of-arrival and directions-of-departure, ii) large delay and angle dispersion by propagation via far clusters, and iii) rank reduction of the transfer function matrix. We propose a geometry-based model that includes t

Hosts can in principle employ two different strategies to defend themselves against parasites: resistance and tolerance. Animals typically exhibit considerable genetic variation for resistance (the ability to limit parasite burden). However, little is known about whether animals can evolve tolerance (the ability to limit the damage caused by a given parasite burden). Using rodent malaria in labora
The objective of this paper is to investigate how the combustion chamber design will influence combustion parameters and emissions in a natural gas SI engine. Ten different geometries were tried on a converted Volvo TD102 engine. For the different combustion chambers emissions and the pressure in the cylinder have been measured. The pressure in the cylinder was then used in a one-zone heat-releas
Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. However, the field is still open
The basic ideas of k(t)-factorization and CCFM parton evolution is discussed. The unintegrated gluon densities, obtained from CCFM fits to the proton structure function data at HERA are used to predict hadronic final state cross-sections like jet production at HERA, but also comparisons with recent measurements of heavy quark production at the Tevatron are presented. Finally, the k(t)-factorizatio
New strategies for prevention and treatment of type 2 diabetes (T2D) require improved insight into disease etiology. We analyzed 386,731 common single-nucleotide polymorphisms (SNPs) in 1464 patients with T2D and 1467 matched controls, each characterized for measures of glucose metabolism, lipids, obesity, and blood pressure. With collaborators (FUSION and WTCCC/UKT2D), we identified and confirmed
A non-associated plasticity theory for granular materials has been developed in Part 1 based on the concept of a characteristic stress state of vanishing incremental dilation. The model is fully three-dimensional and is defined by six material parameters: two for elastic stiffness, one for plastic stiffness, two for the shapes of yield and plastic potential surfaces and one for the dilation at fai
We present an experimental comparison of magnetoconductance fluctuations measured in the ballistic, quasiballistic, and diffusive scattering regimes of semiconductor devices. In contradiction to expectations, we show that the spectral content of the magnetoconductance fluctuations exhibits an identical fractal behavior for these scattering regimes and that this behavior is remarkably insensitive t
Two hundred apparently healthy sexually active women, 17-34 years of age, who had presented for a general health check-up at the Clinic of Dermatology and Venereology, Medical University, Plovdiv, Bulgaria, were asked about genital symptoms, sexual behaviour, contraceptive use and smoking habits, and examined for signs of genital infections. They were searched for genital chlamydial infection, gon
The objective of this study is to analyze whether the trend towards operating on patients with less severe primary hyperparathyroidism (pHPT) than earlier is reflected in a change of preoperative presentation and surgical outcome.
