When Harry Sawyerr wrote his essay "What is African Theology?", published first in African Theological Journal, vol. 4 (1971), it appeared from its contents that he was making short comments about James Cone's Black theology that could have disappeared in the midst of more pressing African theological issues. Sawyerr's article was not primarily intended as a critique of Cone's Black theology; inst
The present work describes a flow injection analysis system incorporating amperometric biosensors for acetate monitoring. Tri-enzyme-modified electrodes were fabricated by immobilizing acetate kinase (AK), pyruvate kinase (PK) and lactate dehydrogenase (LDH) into a poly(ethyleneglycole) diglycidyl ether (PEGDGE) film also containing Brilliant Cresyl Blue (BCB) as an electrochemical mediator. The c
This thesis is based on experimental work carried out during the period 1968-1972. The whole investigation is sponsored by the Swedish Council for Building Research and has been performed at the department of Building Materials at the Lund Institute of Technology. The thesis treats the problem frost resistance of building materials, a problem which is far from beeing solved despite much scientifi
This thesis is concerned with laser based techniques for the measurement of fluid dynamical properties and their application to combusting flowfields or flowfields related to combustion. As an introduction, the theory of turbulent flows and combustion is shortly presented. An overview of laser based measuring techniques is given. Next, seven papers are included. The main topic of papers 1 and 2 is
The basic ideas of k(t)-factorization and CCFM parton evolution is discussed. The unintegrated gluon densities, obtained from CCFM fits to the proton structure function data at HERA are used to predict hadronic final state cross-sections like jet production at HERA, but also comparisons with recent measurements of heavy quark production at the Tevatron are presented. Finally, the k(t)-factorizatio
New strategies for prevention and treatment of type 2 diabetes (T2D) require improved insight into disease etiology. We analyzed 386,731 common single-nucleotide polymorphisms (SNPs) in 1464 patients with T2D and 1467 matched controls, each characterized for measures of glucose metabolism, lipids, obesity, and blood pressure. With collaborators (FUSION and WTCCC/UKT2D), we identified and confirmed
The paper deals mainly with two problems in the epistemology of Frank Plumpton Ramsey. One concerns his account of knowledge, the other his fallibilism. I argue that Ramsey failed to make room for the social aspect of knowledge and, furthermore, that he did not separate the fallibility of our view from its corrigibility. My positive proposal is to combine social reliabilism and corrigibilism with
Popular Abstract in Swedish Avhandlingen behandlar nätverksmekanisk modellering av mekaniska egenskaper hos cellulosafiberfluff. Cellulosafiberfluff består av fibrer utvunna från trä, och används bl a i blöjor och isoleringsmaterial. En nätverksmekanisk modell är en typ av mikro-mekanisk modell. Principen för denna typ av modell är att man gör antaganden för hur materialet fungerar på mikro-nivåA network mechanics model for cellulose fibre fluff is proposed. 2D and 3D versions of the model have been implemented and the influence of various micro-level parameters on the global mechanical performance has been determined by means of computer simulations. Model networks composed of bonded fibres of arbitrary distribution in length, curvature, cross-section, stiffness and strength were inves
The molecular structure of Na,K-ATPase was determined by electron crystallography from two-dimensional crystals induced in purified membranes isolated from the outer medulla of pig kidney. The P2 type unit cell contains two protomers in the E2 conformation, each of them with a size of 65 x 75 x 150 Å3. The , ß, and subunits in the membrane crystals were demonstrated in the crystals with Western bl

Low-molecular weight aromatic compounds were extracted from aqueous samples in a packed high-pressure stainless steel column with supercritical carbon dioxide. A countercurrent flow approach was utilised to remove several phenolic and two non-phenolic compounds with similar aromatic structures directly from aqueous standard solutions as well as a real sample (a lignocellulose dilute-acid hydrolysa
Accuracy of 131I tumor quantification after radioimmunotherapy (RIT) was investigated for SPECT imaging with an ultra-high-energy (UHE) collimator designed for imaging 511-keV photons. METHODS: First, measurements and Monte Carlo simulations were carried out to compare the UHE collimator with a conventionally used, high-energy collimator. On the basis of this comparison, the UHE collimator was sel
Assessing the results of modern cystic fibrosis (CF)-care and estimating the future population and its demography is important to evaluate the treatment regimens and to calculate the future needs of health-care resources.This paper updates previous incidence calculations. It assesses the results of modern CF-care in terms of survival and changing demography in Sweden. The incidence of CF in Sweden
Apoptosis is essential to eliminate secretory epithelial cells during the involution of the mammary gland. The environmental regulation of this process is however, poorly understood. This study tested the effect of HAMLET (human alpha-lactalbumin made lethal to tumor cells) on mammary cells. Plastic pellets containing HAMLET were implanted into the fourth inguinal mammary gland of lactating mice f
We simulate two-dimensional lattices of pulse-coupled oscillators with random natural frequencies, resembling pacemaker cells in the heart. As coupling increases, this system seems to undergo two phase transitions in the thermodynamic limit. First, the largest cluster of frequency entrained oscillators becomes macroscopic. Second, all oscillators frequency entrain, except possibly some isolated on
