There are accelerating trends for the implementation of electronic commerce(e-commerce) as an extra marketing channel for selling products globally via the access of the Internet. This is expected to in¯uence the shape of future cities and the conservation of natural resources. This paper critically reviews the current research work to date regarding the environmental implications of e-commerce. T

BACKGROUND: Consumption of soluble dietary fibre is correlated with decreased postprandial glucose and insulin responses and hence has beneficial effects on the metabolic syndrome. AIM OF THE STUDY: To investigate the effects on postprandial glucose, insulin and triglyceride concentrations of meals enriched with soluble dietary fibres from oats, rye bran, sugar beet fibre or a mixture of these thr

The recognition of a strong etiological relationship between infection with high-risk human papillomavirusses and cervical cancer has prompted research to develop and evaluate prophylactic and therapeutic vaccines. One prophylactic quadrivalent vaccine using L1 virus-like particles (VLP) of HPV 6, 11, 16 and 18 is available on the European market since the end of 2006 and it is expected that a sec

In policy debates about reducing environmental and social harms, political consumerism is often called for by actors from a broad political spectrum. This paper examines traits of deliberative democracy in cases where instruments of political consumerism (eco-labelling, certificates and standards) are developed. The empirical cases are processes surrounding eco-labelled, standardised forestry, foo

Many case-control studies have suggested that higher consumption of fruit and vegetables is associated with a lower risk or pancreatic cancer, whereas cohort studies do not support such an association. We examined the associations of the consumption of. fruits and vegetables and their main subgroups with pancreatic cancer risk within the European Prospective Investigation into Cancer and Nutrition

One hindlimb of a rat was subjected to tourniquet compression (150, 200 and 300 mmHg; 2 h). After 6 days a 10 mm sciatic or tibial nerve graft from the compressed limb was sutured to bridge a 3-4 mm gap in the sciatic nerve of the non-compressed limb. The distances of regenerating sensory axons were measured 6 days post surgery (tibial grafts, 8 days). Compression at 200 and 300 mmHg led to signif

A method combining laser-induced fluorescence and principal component analysis to detect and discriminate between algal and fungal growth on insulator materials has been studied. Eight fungal cultures and four insulator materials have been analyzed. Multivariate classifications were utilized to characterize the insulator material, and fungal growth could readily be distinguished from a clean surfa

Conspicuous heritable polymorphisms are useful to address the question if morph frequencies are stable or whether they fluctuate between generations. Ecological geneticists have studied colour polymorphisms in the past, but there are few long-term studies of genetic dynamics across multiple generations. We studied morph-frequency dynamics and female fecundity in the trimorphic blue-tailed damselfl

No difference in attraction was observed in sibling Artic charr Salvelinus alpinus between water scented by dominant or subordinate major histocompability complex (MHC) identical fish observed in a two-choice fluviarium. In a second experiment, MHC identical sibling donors were given different types of food pellets before the preference test. The test fish showed a significant attraction to the si

Background: The aim of this study was to investigate the influence of contextual (social capital and neo-materialist) and individual factors on sense of insecurity in the neighbourhood. Methods: The 2000 public health survey in Scania is a cross-sectional study. A total of 13,715 persons answered a postal questionnaire, which is 59% of the random sample. A multilevel logistic regression model, wit

Clinical functional magnetic resonance imaging (MRI) occasionally fails to detect significant activation, often due to variability in task performance. The present study seeks to test whether a more flexible statistical analysis can better detect activation, by accounting for variance associated with variable compliance to the task over time. Experimental results and simulated data both confirm th

An U-L-rhamnosidase (E.C. 3.2.1.40) from a newly discovered thermophilic bacterium was expressed in Escherichia coli BL21 DE3 pRIL cells. The cells were immobilized in Ca2+-alginate beads. The temperature of 50 degrees C used in reactions, appeared to be sufficient for making the mesophilic strain porous enough for the substrate to access the cloned thermostable enzyme. Pretreatment of cells with

Steryl esters and triacylglycerol (TAG) are the main storage lipids in eukaryotic cells. In the yeast Saccharomyces cerevisiae, these storage lipids accumulate during stationary growth phase within organelles known as lipid bodies. We have used single and multiple gene disruptions to study storage lipid synthesis in yeast. Four genes, ARE1, ARE2, DGA1, and LRO1, were found to contribute to TAG syn

Murine gammadelta T cells participate in innate immune response against infection of the intracellular bacterium Listeria monocytogenes. In the present report, we analyzed the mechanism of the gammadelta T cell-mediated response against L. monocytogenes infection. gammadelta T cell-enriched spleen cells of L. monocytogenes-infected mice produced IFN-gamma in vitro in response to L. monocytogenes-i

Background: alpha 1-antitrypsin (AAT) serves primarily as an inhibitor of the elastin degrading proteases, neutrophil elastase and proteinase 3. There is ample clinical evidence that inherited severe AAT deficiency predisposes to chronic obstructive pulmonary disease. Augmentation therapy for AAT deficiency has been available for many years, but to date no sufficient data exist to demonstrate its

We show that a dilute harmonically trapped two-component gas of fermionic atoms with a weak repulsive interaction has a pronounced super-shell structure: The shell fillings due to the spherical harmonic trapping potential are modulated by a beat mode. This changes the "magic numbers" occurring between the beat nodes by half a period. The length and amplitude of this beating mode depend on the stre
