To identify factors that regulate the levels of immunoreactive digitalis-like substances (irEDLS) in body fluids, two studies were carried out. Plasma and urine levels of irEDLS were measured in uremic and normal subjects. Extracted material was fractionated (12 fractions) and assayed by digoxin radioimmunoassay. In four fractions, higher levels of irEDLS were found in uremic than in normal plasma

This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. It is also one key issue in achieving efficient supply chain management. We focus our attention on a general distr

The levels of different reactive species, especially those of nitric oxide and peroxynitrite, were determined in streptozotocin-induced diabetic rat tissues, before the development of histopathological damages. Significantly higher steady state free radical concentrations were found in the liver 3 weeks after the onset of diabetes compared to age-matched control groups. Increased nitric oxide leve

Nibe Industrier har vuxit från att vara ett lokalt svenskt bolag till en global koncern med dotterbolag runt om i hela världen. Företaget värnar om sina rötter och har således kvar huvudkontoret i Markaryd där de investerar mycket i produktion lokalt. Examensarbetet utfördes på dotterbolaget Nibe AB i Markaryd inom affärsområdet Climate Solutions med specialinriktning på värmepumpar. Nibe är ett fNibe Industries has grown from being a local Swedish company to a global group with subsidiaries around the world. Nibe has protected its roots and still retains the head office in Markaryd, where they invest heavily in production locally (Nibe Industrier AB, 2020). The master thesis was conducted at the subsidiary Nibe AB in Markaryd within Climate Solutions” business area with a special focus on

Population aging has tremendous economic consequences and generates an unprecedented pressure on the welfare state. As the number and share of ‘dependent’ people grows, the state struggles to finance pensions and health-related costs. In this optic, Sweden is no exception: the mean age of the population, life expectancy and share of people above 65 continuously increase – which warrants the focus

Ice Nucleation Proteins (INP) are integral membrane proteins that aid in forming ice crystals. As the name suggests INP help form ice crystals by forming the nucleus around which water molecules align themselves. Under favourable conditions, these water molecules freeze when associated with the protein. INP are present in numerous organisms, the focus of this project, however, was INP from the bac

Excited states in Ag-96 were populated in fragmentation of an 850-MeV/u Xe-124 beam on a 4-g/cm(2) Be target. Three new high-spin isomers were identified and the structure of the populated states was investigated. The level scheme of Ag-96 was established, and a spin parity of (13(-)), (15(+)), and (19(+)) was assigned to the new isomeric states. Shell-model calculations were performed in various

Popular Abstract in Swedish Det har diskuterats huruvida mäns spermiekoncentration minskat och missbildningar i pojkars könsorgan ökat under den senare delen av 1900-talet. Med säkerhet har dock testikelcancer ökat flerfaldigt under samma tidsperiod. Målet med denna avhandling var dels att undersöka huruvida skånska mäns spermakvalitet hade förändrats under det förra årtiondet, dels att studera saA decrease in male reproductive function, including sperm counts, during the second half of the 20th century, has been postulated. During this period, testicular cancer has increased several-fold. Environmental and lifestyle-related factors have been proposed as explanations for a possible negative trend in male reproductive function. One important lifestyle factor is smoking. However, smoking dur

Background Diabetes has been defined on the basis of different biomarkers, including fasting plasma glucose (FPG), 2-h plasma glucose in an oral glucose tolerance test (2hOGTT), and HbA(1c). We assessed the effect of different diagnostic definitions on both the population prevalence of diabetes and the classification of previously undiagnosed individuals as having diabetes versus not having diabet

The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. Paper I analyses the performance degradation of d

Popular Abstract in Swedish Denna avhandling behandlar storlekskarakterisering av stora molekyler (polymerer) med en ny teknik, nämligen flödesfältflödesfraktionering (flödesFFF). Det aktuella storleksområdet som studerats i avhandlingen är intervallet mellan några få nanometer(nm) upp till en halv mikrometer (um). Storleksbestämningen med flödesFFF baseras på en separation av material med olika dSize, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. In this thesis, a relatively novel technique, asymmetrical flow field-flow fractionation (flow FF

One of the challenges in the field of biosensors and biofuel cells is to establish a highly efficient electron transfer rate between the active site of redox enzymes and electrodes to fully access the catalytic potential of the biocatalyst and achieve high current densities. We report on very efficient direct electron transfer (DET) between cellobiose dehydrogenase (CDH) from Phanerochaete sordida

AIMS AND OBJECTIVES: To describe the patients' retrospective experiences of the information and support they received while on the heart or lung transplant waiting list. BACKGROUND: Patients differ in the way that they cope with the time spent waiting for a heart or lung transplant. Patients must already before the transplantation be taught about a new lifestyle, risk factors, medication, food res

The structure, stability, and hydrolysis characteristics of beta-lactoglobulin (LG) A are different from those of either beta-LG B or beta-LG C. Purified samples of these proteins were hydrolyzed with trypsin and the rates of loss of native monomeric beta-LG structure were measured using sodium dodecyl sulfate PAGE. At the same time, the appearance of many individual peptides were identified and f

Abstract in UndeterminedBearing in mind the potential and importance of enzymatic processes it is somewhat surprising that we are not yet able to fully exploit the possibilities that such processes offer. The main reason is that we do not know the mechanism on the molecular scale in terms of the interaction between the enzyme and the substrate or rather the assembly of substrate molecules (see Fig

Phosphine derivatives of alkylidyne tricobalt carbonyl clusters have been tested as catalysts/catalyst precursors in intermolecular and (asymmetric) intramolecular Pauson-Khand reactions. A number of new phosphine derivatives of the tricobalt alkylidyne clusters [Co(3)(mu(3)-CR)(CO)(9)] (R = H, CO(2)Et) were prepared and characterised. The clusters [Co(3)(mu(3)-CR)(CO)(9-x)(PR'(3))(x)] (PR'(3) = a
