Human papillomavirus (HPV) type 16 is the major cause of cervical carcinoma, the incidence of which is decreasing in western countries. In Finland the incidence is, however, increasing in women aged <40 years, but possible underlying changes in HPV-16 epidemiology are unknown. To assess incidence trends of HPV infections, paired sera from a random sample of 8000 women with two pregnancies/sera wit

he aim of this study was to explore aspects of the meaning of home as experienced by very old single-living people in Sweden. A grounded theory approach was used, and interviews were conducted with 40 men and women aged 80-89. The findings indicate that home has a central place in the lives of very old people because it is where they live and spend so much time. The significance of the home is bas

A third order conservative reconstruction, in the context of finite volume schemes for hyperbolic conservation laws, is constructed based on logarithmic functions. This logarithmic method reconstructs without the use of a limiter, any preprocessing of input data, special treatments for local extrema, or shock solutions. Also the method is local in the sense that data from only the nearest neighbor

Fluence-response relationships for the enhancement of ultraweak luminescence by UV radiation were determined in leaves of Brassica napus L. (cv. Ceres) when either the adaxial or abaxial leaf surface was exposed to monochromatic radiation (270–340 nm). Action spectra for both leaf surfaces were constructed from the fluence-response curves at the fluence required to obtain a doubling of the ultrawe

Transient-state kinetic experiments and analyses have been performed to examine the validity of hitherto unchallenged evidence proposed to be indicative of a channelled transfer of triose phosphates from aldolase to glyceraldehyde-3-phosphate dehydrogenase and glycerol-3-phosphate dehydrogenase. The results lend no support to such proposals, but show that the kinetic behaviour of the examined aldo

The homogenization of the Maxwell equations at fixed frequency is addressed in this paper. The bulk (homogenized) electric and magnetic properties of a material with a periodic microstructure are found from the solution of a local problem on the unit cell by suitable averages. The material can be anisotropic and satisfies a coercivity condition. The exciting field is generated by an incident field

Several principal aspects and components of an advanced catalytic exhaust after-treatment system for NO, reduction on a heavy-duty diesel truck engine have been systematically examined and evaluated. The after-treatment system consists of de-NO, catalysts, injection of a reducing agent (diesel fuel), and computer programs to model the engine and catalysts in real time. These models are combined wi
