The pseudo-rapidity dependence of the elliptic flow at various excitation energies measured by the PHOBOS Collaboration in Au+Au collisions at RHIC is one of the surprising results that has not been explained before in terms of hydrodynamical models. Here we show that these data are in agreement with theoretical predictions based on perfect fluid hydrodynamics. We also show that these PHOBOS data
The structures of N-t-butyl-2-(diphenylphosphino)benzylammoniumchloride and N-t-butyl-2-(diphenylphosphino)benzylaminediacetatepalladium(II) have been determined by X-ray crystallography. The Pd-complex was prepared by treating palladiumdiacetate with N-t-butyl-2-(diphenylphosphino)benzylamine in CH2Cl2 for 4 h at room temperature. The organic compound crystallises in the monoclinic space group P2
Palaeoecological methods were applied to peat and sediment cores recovered from one bog (Bråtamossen) and two lakes (Avegöl and Femtingagölen) in the Småland Uplands, southern Sweden. The general aim was to reconstruct the landuse and vegetation history for the last 6000 years in this agriculturally marginal region. The main technique was pollen analysis, which was complemented by mineral magnetic
Many natural scientists foster the idea of a degrading environment, caused by over-exploitation of the resources, being the cause of famine and poverty in Africa. In accordance with this, policies aimed at restoring the environment are formulated. This article analyses the main causes of famine, i.e. drought, desertification and the food market, with examples from the 1984-85 famine in the Sudan.
The structures of 2(diphenylphosphino)acetophenone and bis(2(diphenyl phosphino)acetophenone)palladium(II)bistriflate have been determined by X-ray crystallography. The ligand is of interest because its P,O donor set combines the hard and soft properties. In the Pd-complex, which was prepared by treating tetrakisacetonitrile-palladium-bistriflate with 2-(diphenylphosphino)acetophenone in dichlorom
Croplands are vital ecosystems for human well-being and provide important ecosystem services such as crop yields, retention of nitrogen and carbon storage. On large (regional to global)-scale levels, assessment of how these different services will vary in space and time, especially in response to cropland management, are scarce. We explore cropland management alternatives and the effect these can
We aimed to study differences in the prescribing of warfarin, aspirin and statins to patients with atrial fibrillation (AF) in socio-economically diverse neighborhoods. We also aimed to explore the effects of neighborhood deprivation on the relationship between CHADS2 risk score and warfarin prescription.
Here we present a study of the relationship between July-August (JA) mean climate over China, which is strongly linked to the East Asian summer monsoon (EASM), and the summer (JA) North Atlantic Oscillation (SNAO). The variations of temperature, precipitation, and cloud cover related to the SNAO were analyzed for the period 1951-2002 using gridded data sets as well as instrumental data from 160 st
The ocean heat transport into the Arctic and the heat budget of the Barents Sea are analyzed in an ensemble of historical and future climate simulations performed with the global coupled climate model EC-Earth. The zonally integrated northward heat flux in the ocean at 70A degrees N is strongly enhanced and compensates for a reduction of its atmospheric counterpart in the twenty first century. Alt
Background: The Perceived Stress Scale (PSS) measures general stress and the Swedish version, although used in several studies, has not been extensively evaluated for psychometric properties. Aims: This study aimed to investigate psychometric properties and the factor solution of the Swedish 14-item version when used with two samples, namely a mixed Internet sample of women and men (n = 171) and a
A total synthesis of transtaganolide E and F, proposed intermediates in the biosynthesis of the potent transtaganolides, including an Ireland-Claisen rearrangement and a high-pressure intramolecular Diels-Alder cycloaddition reaction of an unactivated 2-pyrone derivative, is reported. The implication of the results to the proposed transtaganolides biosynthesis is discussed.
BACKGROUND Linomide, Figure 1, produces robust and consistent in vivo growth inhibition of prostate cancer models via its anti-angiogenic activity and inhibition of autoimmune encephalomyelitis models of multiple sclerosis (MS). MS clinical trials were discontinued because of unacceptable toxicity, due to dose-dependent induction of proinflammation. METHODS Therefore, linomide analogs were initia
Agricultural intensification based on smallholders is among many economists viewed as a necessary developmental path to ensure food security and poverty reduction in sub-Saharan Africa. Increasingly, a one-sided focus on raising productivity in cereals has been questioned on environmental grounds, with the concept of sustainable agricultural intensification (SAI) emerging from the natural sciences
When responses to international crimes are managed in terms of post-conflict justice, this event may end 'the demarcation debate' before it has begun, thereby rendering it superfluous among legal scholars. This is to say that the transition from theory to reality arguably has the effect of cancelling any sharp distinction between international criminal law, international human rights law and inter
The promotion of locally produced food has been a growing marketing trend in recent years. Locally produced food is associated with positive values such as environmental benefits, fresher and safer products as well as contributing to building closer ties between people in local communities. We use a case study were a local fish auction was established in the Stockholm area in Sweden with the aim t
M. B. Hintikka (1939–1987) and J. Hintikka (1929–2016) claimed that their reconstruction of the ‘Sherlock Holmes sense of deduction’ can “serve as an explication for the link between intelligence and memory” (1983, p. 159). The claim is vindicated, first for the single-agent case, where the reconstruction captures strategies for accessing the content of a distributed and associative memory; then,
