Popular Abstract in Swedish Skeletthälsa och livsstilsbeteenden hos unga kvinnor I Sverige kommer ungefär 50 % av alla kvinnor att drabbas av en fraktur någon gång under sitt liv. Ett starkt skelett med hög mängd benmassa är det som främst bidrar till att förebygga benskörhetsfrakturer. Kvinnor har efter ungdomsåren mindre mängd benmassa än män och mängden benmassa minskar hos kvinnor snabbare i The overall aim of this prospective observational study with a salutogenic approach was to investigate bone mineral density (BMD) and BMD changes in the heel bone, in a group of healthy women, in relation to physiological factors and lifestyle behaviours over a two-year period as well as investigating the women’s view of their lifestyle behaviours. Data were collected in 1999 (T1) and 2001 (T2). H

Nitro blue tetrazolium (NBT) is an artificial electron acceptor which has been suggested to be a useful tool in studies of free radicals. To establish whether NBT could be useful in morphological demonstration of free radicals in the retina, the staining pattern was examined in normal rat retina and after incubation with the free radical scavenger superoxide dismutase or with inhibitors of free ra

In this letter, we address the antenna subset selection problem in spatially correlated multiple-input multiple-output (MIMO) channels. To reduce the severe performance degradation of the traditional antenna selection scheme in correlated channels, we propose to embed fast Fourier transform operations in the RF chains. The resulting system shows a significant advantage both for diversity schemes a

Streamflow in the Himalayan rivers is generated from rainfall, snow and ice. The distribution of runoff produced from these sources is such that the streamflow may be observed in these rivers throughout the year, i.e. they are perennial in nature. Snow and glacier melt runoff contributes substantially to the annual flows of these rivers and its estimation is required for the planning, development

The goal of endocrine therapy in breast cancer is to block the action of estrogen on the tumor cells either by inhibiting estrogen from binding to the specific estrogen receptor or by inhibiting its synthesis. Tamoxifen, a selective estrogen receptor modulator, is the standard endocrine treatment for hormone receptor-positive breast cancer, both in the adjuvant and metastatic settings. Tamoxifen i

Using a frequency-chirped ring dye laser, we have stored and recalled as much as 48 bits of information with the copropagating stimulated-echo geometry on the H-3(4)-D1(2) transition in Pr3+:YAlO3. Since the copropagating excitation scheme has all the excitation pulses spatially overlapping, this technique will be useful to the practical implementation of stimulated-echo memory because there is no

We study effects on the W mass measurements at LEP2 from non-perturbative interference effects in the fully hadronic decay channel. Based on a model for Bose-Einstein interference, which is in agreement with LEP1 data, we argue that there are no Bose-Einstein correlations between bosons coming from the different W's. For small reconnection probabilities we rule out the possible experimental signal

Popular Abstract in Swedish Avhandlingen handlar om tes av periodicitet och trend inom långminne-processer. Med hjälp av diskret wavelet transform och periodogram presenteras vi två test för periodicitet och tre test för trend. Vi utvärderar vår test samt studerar deras egenskaper delvis genom att använda oss av datorintensiva metoder såsom Monte Carlo och delvis genom att jämföra dem med andra liThis thesis presents methods of testing the periodicity and trend for the time series, which exhibit dependence over long periods of time. Many such processes can be modeled by a class of models called fractionally differenced processes. The first approach we consider to analyse such processes is by using the band periodogram, which divides the periodogram into different intervals or bands, matchi

In decerebrated, nonanesthetized cats, we made intracellular whole-cell recordings and extracellular cell-attached recordings from granule cells in the cerebellar C3 zone. Spontaneous EPSPs had large, relatively constant peak amplitudes, whereas IPSPs were small and did not appear to contribute substantially to synaptic integration at a short time scale. In many cases, the EPSPs of individual moss

Connections between interpolation spaces, Pick functions, and matrix monotone functions are investigated. Characterizations, inclusion results, open problems, and conjectures on these function classes and their interrelations are presented.

Objective: To compare the performance of the American College of Rheumatology (ACR), European League Against Rheumatism (EULAR), and simple disease activity index (SDAI) response criteria for rheumatoid arthritis at the individual level in an observational cohort. Methods: 184 outpatients were followed using a structured protocol. For each patient, the responses according to ACR 20% and 50%, EULAR
