CALIBRATION OF CHROMATOGRAPHY MODELS

AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. The aim of the work presented in the thesis was to develop methods for determining these unknown model parameters.The fundamental approach adopted to de

Associated physical disease in a demented population

Clinical experience indicates that physical diseases are probably underdiagnosed in patients suffering from dementia. We investigated the prevalence of physical diseases in patients with different types of dementia by means of a retrospective patient record survey including 236 inpatients and outpatients referred for dementia evaluation to the Dementia Investigation Unit, University Hospital in Li

Impact of different forming fabric parameters on sheet solids content during vacuum dewatering

The effects of fabric parameters on paper sheet solids content during vacuum dewatering of low grammage sheets was studied by lab. equipment for 10 different forming fabrics. Caliper, void vol., and air permeability that control the capacity of the fabric to enclose water within the fabric were shown to have a great impact on the dewatering of the sheet. Rewetting from fabric to sheet seemed to be

Uncertainties and recommendations

An assessment of the impacts of changes in climate and UV-B radiation on Arctic terrestrial ecosystems, made within the Arctic Climate Impacts Assessment (ACIA), highlighted the profound implications of projected warming in particular for future ecosystem services, biodiversity and feedbacks to climate. However, although our current understanding of ecological processes and changes driven by clima

Rheumatological manifestations, organ damage and autoimmunity in hereditary C2 deficiency.

Objective. To analyse rheurnatological manifestations, organ damage and autoimmune responses in a large cohort of patients (n = 45) with homozygous C2 deficiency (C2D) and long-term follow-up. Methods. Medical records were reviewed and were supplemented with a mailed questionnaire for assessment of cardiovascular disease (CVD) risk factors. Organ damage was evaluated using the Systemic Lupus Inter

Scientific evidence changes prescribing practice - a comparison of the management of the climacteric and use of hormone replacement therapy among Swedish gynaecologists in 1996 and 2003

Objectives To study changes in attitudes, knowledge and management strategies concerning hormone replacement therapy (HRT) among gynaecologists in Sweden. Design Comparative questionnaire study. Setting National survey. Population Practising gynaecologists. Methods In 1996, gynaecologists in Sweden (n = 1323) were invited to return a postal questionnaire concerning their attitudes, knowledge and m

The popliteal artery, an unusual muscular artery with wall properties similar to the aorta: Implications for susceptibility to aneurysm formation?

Objective. The popliteal artery is, after the aorta, the most common site for aneurysm formation. Why the popliteal artery is more susceptible than other peripheral muscular arteries is unknown. An important factor may be differences in arterial wall composition as compared with other peripheral muscular arteries, which in turn affect wall properties. These are however unknown. We studied the mech

Development of Feedback Microwave Thermotherapy in Symptomatic Benign Prostatic Hyperplasia.

Popular Abstract in Swedish Abstract: Denna avhandling utvärderar CoreTherm systemet och dess metod för mikrovågsbehandling (TUMT), ProstaLund Feedback Treatment (PLFT), vid symtomgivande ålderförstorad prostata (BPH). Avhandlingen belyser biofysik, verkningsmekanismer, behandlingsindikationer, tilläggsmetoder, effektivitet och säkerhet vid PLFT. Två biofysiska ekvationer kan appliceras i en beräkAbstract: The purpose of this thesis was to evaluate ProstaLund Feedback Treatment® (PLFT®) and the CoreTherm® device with regard to biophysics, mechanisms of action, treatment indications, additional techniques, efficacy and safety in the treatment of patients with benign prostatic hyperplasia (BPH). The application of two biophysical equations in the PLFT software is explained. The calculations

The 5 angstrom structure of heterologously expressed plant aquaporin SoPIP2;1

SoPIP2;1 is one of the major integral proteins in spinach leaf plasma membranes. In the Xenopus oocyte expression system its water channel activity is regulated by phosphorylation at the C terminus and in the first cytosolic loop. To assess its structure, SoPIP2;1 was heterologously expressed in Pichia pastoris as a His-tagged protein and in the non-tagged form. Both forms were reconstituted into

The Lifetime of the Proton-decaying 8915 keV State in 58Cu

Energy correlations between gamma -ray transitions and the prompt proton decay line in Cu-58 were studied by means of the fusion-evaporation reaction Ca-40(Mg-24,1 alpha 1p1n) using the EUROBALL spectrometer coupled to ancillary detector devices. A lifetime of 0.06 < tau < 0.58 ps for the 8915 keV proton-decaying state in Cu-58 is deduced. (C) 2001 Elsevier Science B.V. All rights reserved.

A randomised study in all cervical hip fractures Osteosynthesis with Hansson hook-pins versus AO-screws in 199 consecutive patients followed for two years

A consecutive series of patients with all types of cervical hip fracture (both undisplaced and displaced) were randomised to osteosynthesis with Hansson hook-pins (n = 98) or AO-screws (n = 101). Background parameters, fracture type and reduction of the fracture did not differ significantly between the groups. Fifty-seven percent of the patients were operated on within 6 h of admission to hospital

Archaeo-faunal aspects of bog finds from Hassleberga, southern Scania, Sweden

In recent years, small bogs at Hassleberga in southwestern Scania have been turned into crayfish ponds after the removal of the organic sediments. Bones and antlers were noticed in the excavated material and have been systematically collected. The finds include reindeer of both sexes and of different ages. Bones of wild horse, elk, arctic hare and arctic fox were also identified. Radiometric datin

Litteraturens makt

Har litteraturen makt att påverka människan och samhällsutvecklingen? Är det verkligen så att litteraturen har hjälpt till att avskaffa slaveriet i Amerikas sydstater eller att ge svenskarna religiös mötesfrihet? Kan den ha skadat äktenskapet som institution eller gett avgörande synpunkter inom barnuppfostran? Har den inspirerat FN i miljöfrågor, gett svenskarna dräpande argument i kärnkraftsdebat

Formation of Rhodium Carbonyl Cluster Thiolates with Concomitant H2 evolution

Reaction of [Rh6(CO)15(NCMe)] with p-thiocresol [(4-Me)C6H4SH] leads to the formation of [Rh2(CO)4(μ-SC6H4CH3)2] as the main product along with a small amount of [Rh6(CO)16]. An approximately 30-fold excess of the thiol is required in order to obtain a good yield of the thiolate-bridged dimer while reaction of [Rh4(CO)12] with an excess of p-thiocresol leads to an apparently clean conversion to th
