One of the main features of the European nutritional transition involved the wide-spread increase in milk consumption, a singular process as it involved the emergence of new consumption preferences. This transformation will be examined here using Spain as a case study. Even up until the 1890s milk was not considered a valuable dietary component in Spain, and was normally consumed only by those who were on liquid diets for medical reasons. By the 1930s, however, milk was regarded as a basic foodstuff, especially for children. Our main hypothesis is that cities played a central role in this change in preferences. Large population centres provided an avenue to spread new knowledge of nutrition and food hygiene, while cities allowed social economies of scale that made it easier to implement new public hygiene measures and to publicize or distribute new products. We also show that the spreading of milk consumption in cities progressed slowly in Spain, because until well into the twentieth century supply could only rely on short-range distribution networks.

We are wholly dependent upon energy of solar, terrestrial and celestial origin. Contributions from any basically new form of energy are unlikely. Fossil fuels are the basis of modern economies, crude oil being dominant.Overall energy demand and the considerable, special merits of crude oil and natural gas will lead to enormous demand for these two commodities in the coming decades. Oil and gas lend themselves to the economies of scale which are as important as technical factors. Vigorous and efficient world-wide exploration and research and development in improved recovery would appear urgent and important. A shortfall in these commodities could have serious economic repercussions world-wide. A massive shortfall could be disastrous.Research and development in coal, oil shale, tar sands, heavy oil, nuclear fracturing of reservoir rocks and fundamental issues to improve overall efficiency in using resources are worth early expenditure. Doubling total system efficiency or recovery percentage would each be equivalent to doubling proven reserves.Australia seems fairly well endowed with natural gas and brown coal but the locations with respect to large population centres are less than ideal. Reserves of uranium are also substantial. There could be serious shortages of black coal and oil resources. A good balance of components might not be easy to achieve if national security were given due weight. For example, to maintain its industrial economic growth Australia needs imported crude oil as a major contributor to primary energy consumption in spite of vulnerability to foreign control of supply and price.

AbstractAlthough previous studies reported a link between sleep problems and the occurrence of hallucinations, more detailed information is needed to translate this association into clinical practice. This study investigates sleep quality and its relation to prevalence, type, content, and phenomenology of hallucinations, using an online survey in a large population sample (n = 10,299). Based on community-based cluster analysis, four groups could be distinguished that differed in terms of sleep quality. Our results confirm previous studies in showing that poor sleep is associated with the occurrence of hallucinations, and extend previous results on a number of aspects. First, we show that particularly fragmented sleep relates to the occurrence of hallucinations. Second, we show that this is the case for hallucinations across the auditory, visual, olfactory, and tactile domains. Third, our results show that fragmented sleep not only relates to the occurrence, but also to the content, frequency, duration, and associated distress of hallucinations. Finally, compared to poor sleep, good sleep quality is associated with hallucinations that are less negative and disruptive. We conclude that sleep hygiene measures could have a large positive impact on individuals whose fragmented sleep underlies the occurrence of bothersome hallucinations.

Irritable Bowel

Psyllium hydrophillic mucilloid is a natural gelling fiber consumed by a large population of our society. It is used as a bulk-producing laxative and in the treatment of gastrointestinal disorders such as “Irritable Bowel Syndrome”. The literature pertaining to the ultrastructural effects of this agent is sparse.This study documents morphological changes induced by psyllium. Animals fed a diet containing 2% psyllium for four weeks were subsequently sacrificed and processed for scanning and transmission electron microscopy. The colon contained fecal material combined with psyllium which conformed to the contour of the luminal surface. This mixture formed surface replicas of the intestinal mucosa. These replicas and their related colonic sites were processed for morphologic analysis.

Abstract. Early detection of vascular damage in atherosclerosis and accurate assessment of cardiovascular risk factors are the basis for appropriate treatment strategies in cardiovascular medicine. The current review focuses on non-invasive ultrasound-based methods for imaging of atherosclerosis. Endothelial dysfunction is an accepted early manifestation of atherosclerosis. The most widely used technique to study endothelial function is non-invasive, flow-mediated dilation of the brachial artery under high-resolution ultrasound imaging. Although an increased intima-media thickness value is associated with future cardiovascular events in several large population studies, systematic use is not recommended in clinical practice for risk assessment of individual persons. Carotid plaque analysis with grey-scale median, 3-D ultrasound or contrast-enhanced ultrasound are promising techniques for further scientific work in prevention and therapy of generalized atherosclerosis.

Abstract. Physical exercise when done excessively may have negative consequences on physical and psychological wellbeing. There exist many scales to measure this phenomenon. The purpose of this article is to create a scale measuring the problematic practice of physical exercise (PPPE Scale) by combining two assessment tools already existing in the field of exercise dependency but anchored in different approaches (EDS-R and EDQ). This research consists of three studies carried out on three independent sample populations. The first study (N = 341) tested the construct validity (exploratory factor analysis); the second study (N = 195) tested the structural validity (confirmatory factor analysis) and the third study (N = 104) tested the convergent validity (correlations) of the preliminary version of the PPPE scale. Exploratory factor analysis identified six distinct dimensions associated with exercise dependency. Furthermore, confirmatory factor analysis validated a second order model consisting of 25 items with six dimensions and four sub-dimensions. The convergent validity of this scale with other constructs (GLTEQ, EAT26, and The Big Five Inventory [BFI]) is satisfactory. The preliminary version of the PPPE must be administered to a large population to refine its psychometric properties and develop scoring norms.
