Mobile phones become smaller but include more advanced functions for every new generation. This paradox is possible since reduced transistor size and increased integration of digital building blocks free space for new functions. Unfortunately, not all components are easily integrated or scaled, such as the antenna, since its performance is dependent on the size. Shrinking mobile phone size results

To characterize prostate-specific antigen (PSA) produced by cancer cells, different isoforms of PSA secreted by the human prostate cancer cells, LNCaP, were purified. LNCaP-PSA production was induced by synthetic androgen, R1881. LNCaP-PSA was separated into four pools. The molecular mass of LNCaP-PSA isoforms in these pools was 34 kDa under reducing conditions and 29 kDa under nonreducing conditi

The twin hook has been developed as an alternative to the conventional lag screw to be combined with a barrelled side-plate in the treatment of trochanteric hip fractures. With two oppositely directed apical hooks introduced into the subchondral bone of the femoral head, the twin hook provides different stabilising properties to the lag screw. The femoral head purchase of the twin hook and the lag

In this paper we discuss the possibility of a general paradigm for cell-biomaterial and cell-nanoparticle interactions. The basis of the paradigm is that the nature of the biomaterial or nanoparticle surface is not the important parameter, but rather the nature of the outermost layer of adsorbed proteins as well as long-lived misfolded proteins shed from the surfaces. If the adsorbed protein is ir

The purpose of this report is to design a thickness controller fo a hot rolling mill. The thickness control problem is difficult and small improvements make large savings possible. It is therefore relevant to use advanced control strategiesfor controlling the plate thickness. In the report a short introduction to the thickness control problem, and a description ofhow thickness control is done toda

Formaldehyde (CH2O) is an important intermediate species in combustion processes and it can through laser-induced fluorescence measurements be used for instantaneous flame front detection. The present study has focussed on the use of the third harmonic of a Nd:YAG laser at 355 nm as excitation wavelength for formaldehyde, and different dimethyl ether (C2H6O) flames were used as sources of formalde

Conclusions. Thorough otomicroscopical examination of the tympanic membrane in acute otitis media (AOM) might distinguish AOM episodes caused by different bacteria. It thus might be a way to select appropriate treatment for each patient without raising the number of dangerous complications. Objectives. The aim of this study was to see if it might be possible to predict the causative bacterium by j

To compare the clinical and microbiological efficacy of azithromycin in curing chlamydial infections in women with that of lymecycline, and with a view of the possibility of minimizing the problem of compliance by means of single-dose administration, 146 women with culture-positive Chlamydia trachomatis infections were randomly assigned to treatment with a 1 g bolus dose of azithromycin or a 10-da

Environmental manipulation experiments showed that species respond individualistically to each environmental-change variable. The greatest responses of plants were generally to nutrient, particularly nitrogen, addition. Summer warming experiments showed that woody plant responses were dominant and that mosses and lichens became less abundant. Responses to warming were controlled by moisture availa

Many concrete dams, and other concrete structures within the hydropower industry are old and in a more or less severe state of degradation. Leaching is, together with freeze-thaw, the most common degradation problem in Swedish hydraulic concrete structures. This report contains a literature survey of concrete leaching, and presents the results of an experimental determination of leaching.

alpha 1-Antitrypsin (AAT), a major endogenous inhibitor of serine proteases, plays an important role in minimizing proteolytic injury to host tissue at sites of infection and inflammation. There is now increasing evidence that AAT undergoes post-translational modifications to yield by-products With novel biological activity. One Such molecule, the C-terminal fragment of AAT, corresponding to resid

Objective: to describe the trends of self-reported past consumption of alcoholic beverages and ethanol intake from 1950. to 1995 within the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: Data-on consumption of beer/cider, wine and liqueur/spirits were obtained age 20, 30 and 40 years to calculate average consumption and retrospectively at ethanol intake for the time p
