Vertebral fractures are associated with back pain and disability. There are, however, few prospective data looking at back pain and disability following identification of radiographic vertebral fracture. The aim of this analysis was to determine the impact of radiographically identified vertebral fracture on the subsequent occurrence of back pain and disability. Women aged 50 years and over were r
Models can play a fundamental role while moving from nourishment projects to nourishment plans, i.e., when nourishment becomes an integral component of a coastal management strategy. Planning nourishment in the context of a multi-years management strategy requires more significant prediction skills than available in the past and an awareness of dealing with uncertainty. The present paper introduce
The copolymer of N-isopropylacrylamide (NIPAM) and methacryloyl derivative of spirobenzopyran (MSBP) with a molecular weight of 21 000 g/mol and the average molar MSBP content of 1.9% was prepared by free radical polymerization. The copolymer displayed its phase transition in water in the temperature range of 30-50 degreesC. UV irradiation of its aqueous solution caused photoinduced transformation
Two methylcelluloses (MC) were investigated by partial hydrolysis followed by direct infusion electrospray ionisation mass spectrometry (ESI-MS). Partial hydrolysis was achieved either enzymatically or by acid hydrolysis. Enzyme hydrolysis was performed using the endoglucanase Bacillus agaradhaerens Cel 5a. Three different hydrolysis buffer solutions were investigated in order to deter-mine which
The effects on the energy situation in industry when gas fired liquid heaters replace steam have been determined by energy surveys performed in a brewery and a slaughterhouse, measurements of the performance and emissions from liquid heaters installed in these industries, and theoretical analyses of the potential energy saving. The theoretical study in the first part of the project provides infor
The computation of the Capon and the amplitude and phase estimation (APES) filters can be very time consuming. The burden lies not only in the inversion of the sample covariance matrix, but also in the matrix multiplications. In this paper, we propose an efficient algorithm for the computation of the above mentioned filters, using Cholesky factorization and fast Fourier transforms. Furthermore, we
Popular Abstract in Swedish Alla har vi väl någon gång varit med om att datorer, dataprogram och datasystem inte fungerar som vi har tänkt oss. Inte sällan inträffar det fel och konstigheter som kan vara frustrerande och, i värsta fall, direkt farliga. Många gånger undrar man hur ett visst program eller system skall användas och hur de som har designat och byggt det har tänkt och resonerat. I stoThis work is about IT quality and systems developers' knowledge and view of it. IT quality is considered as the characteristics of a system or program that influence e.g. the experience of using it, the easiness to learn and understand it, how it could be customised according to new demands, and the possibility for those who have developed it to understand how it works and can be enhanced. There a
Evidence is presented to show that the presence of a channelled reaction branch in a coupled two-enzyme reaction leads to a slower overall relaxation of the system towards steady state following perturbations of the reaction conditions. A predominant part of the total reaction flux change resulting from perturbations may be governed by transients that are more rapid in the presence than in the abs
Eutrophication and persistent pollutants are two of the main environmental problems in European marine and freshwater ecosystems. As they tend to co-occur, interactive processes between eutrophication and contaminants are suggested, that may lead to environmental effects that cannot be predicted from each process alone. In order to predict the consequences of remedial measures (changing the input
Recurrent major depressive disorder with regular seasonal patterns, commonly known as seasonal affective disorder (SAD), has evoked substantial research in the last two decades. It is now recognised that SAD is a common condition with prevalence rates between 0.4% and 2.9% of the general population, and that patients with SAD experience significant morbidity and impairment in psychosocial function
The quark mixing matrix is parameterised such that its "Cabibbo substructure" is emphasised. One can choose one of the parameters to be an arbitrarily chosen angle of the unitarity triangle, for example, the angle beta (also called Phi(1)).
Functional data analysis is used to examine articulatory variability across repetitions in normal speech, under different movement constraints. A temporal normalization technique is applied to align trajectories of lips, jaw, and tongue in vowel-consonant-vowel sequences. Next, an index of amplitude variability is computed, defined as the mean standard deviation between peak velocities of the cons
