Effective communication is of crucial importance for the development of effective social organisations. Deficient communication combined with rapid technological and social changes appears to lead to both ecological and psychological imbalance. An increasing number of environmental groups are working for ecological improvements, but young people seem to find it increasingly difficult to master the
Wastewater treatment plant operators encounter complex operational problems related to the activated sludge process and usually respond to these by applying their own intuition and by taking advantage of what they have learnt from past experiences of similar problems. However, previous process experiences are not easy to integrate in numerical control, and new tools must be developed to enable re-
This study seeks to advance the understanding of board empowerment in small companies. Predictions based on agency and resource dependency theories were used to examine how contingency factors correlate with board empowerment, in this study conceptualized as a larger number of board members, a higher representation of outside directors, and separate CEO and board chair positions. Statistical analy
A population of cerebrovascular nerve fibers have recently been found to store serotonin (5-hydroxytryptamine; 5-HT). There is reason to assume that these 5-HT-containing fibers have a sympathetic rather than an intracerebral origin. This was further elucidated in the present study in which the uptake mechanisms of 5-HT and noradrenaline (NA) were characterized and compared in rat pial arteries by
Reduction of energy use in buildings is fundamental for sustainable development. A computer program for the prediction of energy use in buildings was assessed by comparisons with the energy performance of existing buildings. The program was then used to evaluate the energy saving characteristics of concrete such as air tightness and heat capacity. The impacts on global environmental aspects and li
Objective: To investigate the potential of acetic acid supplementation as a means of lowering the glycaemic index (GI) of a bread meal, and to evaluate the possible dose - response effect on postprandial glycaemia, insulinaemia and satiety. Subjects and setting: In all, 12 healthy volunteers participated and the tests were performed at Applied Nutrition and Food Chemistry, Lund University, Sweden.
A control diet without supplemental fat and four diets containing 8% of coconut oil, rapeseed oil, fish oil or sunflower oil were fed to lactating sows in order to investigate the lipid absorption capacity of their progeny in terms of pancreatic enzyme activity, hormonal regulation, and bile salt concentration. In addition, the effect of age was studied during the four week suckling period, and du
Hyperplasia of middle-ear mucosa (MEM) during otitis media (OM) is thought to be partially mediated by the actions of growth factors and their receptors. The intracellular pathway leading from the small G-protein Ras to the extracellular regulated kinases (Erks) often links growth factor stimulation to cellular proliferation. This study assessed whether this pathway is involved in MEM hyperplasia
Cytogenetic aberrations have been reported in 45,000 human neoplasms. Structural balanced rearrangements are associated with distinct tumor subtypes with remarkable specificity and have been essential for identifying genes involved in tumorigenesis. All balanced rearrangements that have been characterized molecularly act by deregulating a gene in one of the breakpoints or by creating a fusion gene
Rome in Sweden? The Catholic Offensive in Ecumenical-National Context Since World War II, ecumenical principles have been used as historical measures. This has led to re-interpretations of historical events and to alterations of sources, for example the letters and diaries by Elisabeth Hesselblad, the renewer of St. Birgitta’s order. In the literature on the Swedish Archbishop Nathan Söderblom, th
The hydrophilic/hydrophobic properties of the membrane material have an important influence on the membrane flux reduction when treating solutions containing hydrophobic solutes. Different methods of measuring the hydrophobic properties of membranes have been evaluated; measurement of the contact angle being the most commonly used method. In this investigation the flux reduction of eight membranes
Popular Abstract in Swedish Denna studie behandlar huvudsakligen hur företagen väljer att anpassa sig till myndigheternas krav utifrån miljöskyddslagen. Undersökningen fångar en viss historisk tidpunkt då lagstiftning och myndigheter har en viktig betydelse. Det är en mycket dramatisk fas av den miljöekonomiska utvecklingen. I samhället har man inte tidigare artikulerat miljökraven på ett sådant sThis study primarily focuses on the ways in which companies choose to adapt themselves to the demands of the authorities as based on the Swedish environmental protection act. The time during which the burden upon nature became a serious, important question for companies is a very dramatic phase of a historical process. Before the arrival of more comprehensive legislation, no loads upon nature were
The anaerobic fermentation of deproteinized whey with beta-galactosidase coimmobilized with Saccharomyces cerevisiae in calcium alginate gel beads for the production of ethanol has been studied in a continuous horizontal packed bed reactor (HPBR). The results are compared with batch experiments in a stirred tank reactor. The immobilized yeast cells are exposed to conditions that vary with time and
