US-based philanthropies have long contributed to environmental conservation through non-repayable donations, but some are now beginning to embrace novel investment strategies that are profit-orientated. From the vantage points of political economy and geopolitics, this article investigates the potential ramifications of this shift in funding for large-scale marine protected areas (LMPAs), which ha

Self-treatment techniques in patients with paroxysmal atrial fibrillation (PAF) have seldom been described. It has been suggested that PAF attacks might be initiated by changes in the tonus of the autonomic nervous system. Our aim was to study patients’ measures to terminate PAF attacks and to evaluate the possible influence of the autonomic nervous system on start and stop mechanisms.

The cardiovascular regulation in humans depends to a major extent on sympathetic reflexes originating from volume receptors in the arterial as well as the cardiopulmonary region. With experimental approaches, such as lower body negative pressure (LBNP) and tilting, signs of reduced efficiency with ageing have been shown. However, a confounding factor may be an age-related decline in venous capacit

Abstract: (+)‐T‐Cadinol is a sesquiterpene with smooth muscle relaxing properties. In the isolated rat aorta, T‐cadinol relaxed contractions induced by 60 mM K+ in a concentration‐dependent fashion. The dihydropyridine calcium antagonist nimodipine was approximately 4,000 times more potent than T‐cadinol. While both drugs nearly abolished the K+‐induced contractions, they only partially relaxed c

In the 1970s, grassroots disability movements in many countries changed the thinking around disability and disability politics. Nonetheless, they were also part of larger political upheavals in the western world. How were they inspired by the socialist, feminist, and gay and lesbian movements? In addition, how did they relate to non-disabled allies? Organisations in Denmark and Sweden are investig

The effect of lesions of two excitatory afferent pathways on the cellular damage in the hippocampus following complete cerebral ischaemia was investigated in the rat Lesions transecting the perforant path led to a significant decrease in cellular damage in the hippocampal CA1 region ipsilateral to the lesion as compared to the contatterai side and to control. Lesions of the fimbria-fornix, on the

Extracellular levels of striatal γ-aminobutyric acid (GABA) and taurine were monitored during insulin-induced hypoglycemia using microdialysis. At the onset of isoelectricity in the electroencephalogram (EEG), a transient 5-fold increase in the levels of GABA occurred. Taurine levels increased 5 min following the onset of isoelectricity and continued to increase during the entire isoelectric perio

The present paper reports different applications which have a common data source: Automatic Road Analyzer (ARAN) of the Transport Infrastructure Laboratory of the University of Catania. Data surveyed with ARAN were used to develop performance indicators of the road asset. A BIM model makes possible to improve the flexibility in information access and to merge data with the aim to allow a complete

Books and other printed matter are media of communication, used to carry and distribute – mediate – "content". A medium, however, is always material, and as such it produces meaning in its own right. So even though content and medium might be separate and distinct entities, they are intimately connected, and in order to be communicated a piece of "content" is always given one or another material f

During a lightning strike to an aircraft in flight, the lightning channel gets deformed in the airflow and displaced along the aircraft, a so-called swept stroke . The deformation and the displacement are caused by the interaction between the aerodynamic flow and the plasma properties of the channel together with the properties of the surface. We give a theoretical analysis and a numerical modelli
