    Notes: Abstract The aim of this population-based matched case-control study was to evaluate the effect of risk factors for hip fracture in Oslo, Norway, which has some of the highest incidence rates ever reported. The study population comprised all non-institutionalized persons 50 years or older living in the catchment area of two Oslo hospitals, and cases were 246 patients admitted for hip fracture during a 1-year period. The controls were randomly selected from the study population, matched 1:1 for age and sex. Hip fracture was associated with lean body stature, smoking, low grip strength and decreased levels of physical activity, and inversely with length of education. In addition, hip fracture was inversely related to indicators of total food intake (number of meals per day, frequency of dinners, and slices of bread per day). A relation between hip fracture and low vitamin D intake was also suggested, whereas no association with dietary calcium intake was found. Finally, increased risk of fracture was seen in persons reporting two or more hospital admissions in the previous 2 years, and in those reporting weight reduction due to poor appetite during the previous year. In conclusion, the risk factor pattern for hip fracture was much the same in the elderly population of Oslo as previously described in other populations with a lower incidence of fracture. This study also indicates a relation between hip fracture and low food intake.

    Notes: The accuracy by which an unknown concentration profile can be found by analysis of XPS spectra is investigated theoretically by analytical and numerical techniques. The problem of determining the profile is reformulated as an optimization problem. By use of analytical techniques we obtain qualitative statements about the depth resolution and we derive fundamental relationships between the different parameters that indicate their relative importance. In order to illustrate the various dependencies of the variability of the model parameters, we derive analytical expressions for the standard errors of the model parameters for two simple models: a dalta layer and an exponentially decreasing profile. Furthermore, the complete probability distribution of the model parameters for a rectangular model is investigated numerically.

    Notes: It is shown that the accuracy by which a concentration-depth profile can be estimated from the inelastic background of an XPS spectrum is dramatically improved by using two-dimensional (2D) data. The energy loss distribution of the photoelectrons for several values of the detection angle, or the energy of the excitation source, are treated as a single 2D data set. The resolution of the depth profile estimated from this set is far better than can be obtained from any single XPS spectrum.

    Notes: An analytical correction method is proposed to eliminate the problems resulting from numerical Fourier transformation of functions with a broad background. The method incorporates the analytically known or observed asymptotic behaviour into the numerical procedure. The applicability and high accuracy of the background correction method is illustrated by application to the analysis of reflected electron energy-loss spectra.
