In 2012 we celebrate the 125th anniversary of the unique molecule Troger's base (TB), first synthesized by Julius Troger in 1887. Being a V-shaped C2-symmetric chiral molecule, it possesses many interesting features. The TB field was reopened in 1985, when Craig S. Wilcox published the first crystallographic study of TB and described the synthesis and potential applications of TB analogues in supr

This study reexamines the sustainability hypothesis by testing whether government revenues and expenditures for eight rich OECD countries between 1977Q1 and 2005Q4 are cointegrated. For this purpose, a nonstationary panel data approach is adopted, which is general enough to permit for cross-country dependence as well as structural breaks representing major shifts in fiscal policy. In contrast to m

Playfulness is easily overlooked in studies of total institutions because it does not match what we expect from institutional order. By studying playfulness ethnographically, social life in today’s institutions can be depicted both more naturalistically and more unexpectedly. This article explores how members of Swedish youth care institutions enact and respond to playful disputes or aggression in

This paper provides an updated summary and discussion of my 1993 JMS paper 'Organization as rhetoric: knowledge-intensive firms and the struggle with rhetoric', and relate this to my own and others' later work in the area explored in the paper: knowledge-intensive work and discourse. A key aspect of knowledge work is the ambiguity of what it stands for, what people working with 'knowledge' are doi

Epidemiological data regarding tea and coffee consumption and risk of esophageal cancer (EC) is still inconclusive. We examined the association of tea and coffee consumption with EC risk among 442,143 men and women without cancer at baseline from 9 countries of the European Prospective Investigation into Cancer and Nutrition. Tea and coffee intakes were recorded using country-specific validated di

Surgery is performed in up to half of all cases of active infective endocarditis (IE) but the associated mortality remains high. The aim was to examine the effect of the preoperative clinical presentation on long-term survival of patients undergoing surgery for isolated native mitral valve infective endocarditis.

The lack of attention to the role of emotions generally has led modern learning theories to neglect the importance of emulation as a pedagogical support to students’ learning. One reason could be that the influence of teacher personality is not considered in relation to learning outcome. Another reason may be that the concept of emulation has been used as a psychological conception for one-way tra

Intergovernmental Panel on Climate Change (IPCC) Tier 1 methodologies commonly underpin project-scale carbon accounting for changes in land use and management and are used in frameworks for Life Cycle Assessment and carbon footprinting of food and energy crops. These methodologies were intended for use at large spatial scales. This can introduce error in predictions at finer spatial scales. There

The effects of cooling on neuromuscular function and performance during gait are not fully examined. The purpose of this study was to investigate the effects of local cooling for 20 min in cold water at 10 C in a climate chamber also at 10 C on maximal isometric force and electromyographic (EMG) activity of the lower leg muscles. Gait ground reaction forces (GRFs) were also assessed. Sixteen healt

The core-shell nanowires have the promise to become the future building blocks of light emitting diodes, solar cells and quantum computers. The high surface to volume ratio allows efficient elastic strain relaxation, making it possible to combine a wider range of materials into the heterostructures as compared to the traditional, planar geometry. As a result, the strain fields appear in both the c

Although plesiosaurs and mosasaurs co-existed for about 35 million years at the end of the Cretaceous, the fossil record documenting interactions between these two groups of marine reptiles is meagre. The discovery of deeply incised scars on a limb bone of an immature polycotylid plesiosaur from the latest early Campanian (in the European two-fold division of the Campanian Stage) of the Kristianst

PURPOSE: This cross-national qualitative study explores how very old people reflect upon relocation and aging in place. DESIGN AND METHODS: Swedish and German data are utilized in this study. About 80 community-living participants, 80-89 years of age, were interviewed with open-ended questions at home by trained interviewers. The interviews were analyzed by using conventional qualitative content a

In this paper we synthesise previous sedimentological studies and new, high resolution, digital elevation models from southern Småland to investigate the evolution of a deglacial landscape. Starting approximately at the deglacial highest shoreline, there is a 20-40 km wide zone of ribbed and hummocky moraine that can be connected to the predominantly subaqueous Göteborg moraine. North of this ther

Promoting renewable energy sources (RES) has been addressed a key strategy for mitigating climate change, the governing in which has turned out a challenging and protracted task for the EU. There is often an implicit assumption that concern for climate change drives energy policy, but a closer look at the development of European RES policy indicates how EU governors have had to confront a range of

Traumatic brain injury (TBI) is one of the leading causes of death in children worldwide. Emerging evidence suggests that alterations in mitochondrial function are critical components of secondary injury cascade initiated by TBI that propogates neurodegeneration and limits neuroregeneration. Unfortunately, there is very little known about the cerebral mitochondrial bioenergetic response from the i

This article presents a water balance equation for predicting leachate generation in municipal solid waste (MSW) landfills located in semi-arid areas, using the Akaider landfill in Jordan as an example. HYDRUS-2D/3D software was used to model the effect of co-disposal of wastewater into the landfill on the leachate production rates and for comparison with the results of the simulation of the propo

By exploiting the abundant tissues available from Populus trees, 3-4 m high, we have been able to isolate plasma membranes of high purity from leaves, xylem, and cambium/phloem at a time (4 weeks after bud break) when photosynthesis in the leaves and wood formation in the xylem should have reached a steady state. More than 40% of the 956 proteins identified were found in the plasma membranes of al

Epidemiological perspectives applied to the study of socioeconomic inequalities in health are characterized by a one-dimensional approach to social differences, as income, occupation, and education are used as interchangeable variables to capture social inequalities. This paper calls into question this assumption by exploring the impact of parent's education and occupation on their newborns' healt
