The definitions of constipation include a reference to infrequent, difficult or incomplete bowel evacuation that may lead to pain and discomfort; with stools that can range from small, hard ’rocks’, to a large bulky mass. Constipation may be debilitating among those who require chronic analgesia (7); OIC or OBD affected an average of 41 % patients taking an oral opioid for up to 8 weeks in a me...

Pleistocene rock art is abundant in Australia, but has so far received only limited attention. Instead there has been a trend, begun over a century ago, to search for presumed depictions of extinct megafauna and the tracks of such species. All these notions have been discredited, however, and the current evidence suggests that figurative depiction was introduced only during the Holocene, never ...

Reservoir rocks, regardless of what kind (oil-, gasor water-bearing), are classified by their specific properties. Most rock properties, such as storage, permeability, electric conductivity, heat capacity and so on are determined by laboratory experiments and field tests under different external conditions. Besides temperature, pressure and chemical reactions, also the geometry of the pore spac...

A variety of igneous, sedimentary and metamorphic Palaeozoic rocks from Tasmania have similar directions of NRM-steeply upward. Although the mean direction is not significantly difIerent at the 95% confidence level from the present field, its inclination is slightly steeper. Moreover, the palaeomagnetic pole calculated from these directions is closer to Tertiary poles from Australia than to the...

The Swiss Jura is part of a larger region, the Jura, which stretches from Geneva to Germany, partly as a series of folds, partly as tablelands. The mountains were formed during the late phase of the Alpine folding during the Tertiary and are composed of Mesozoic rocks, mainly limestone and clay. The changing strata give way to a particular landscape, and the presence of limestone makes it a vas...

One of the most prominent features on gravity and aeromagnetic maps of the United States is a series of major, generally linear anomalies that extend from central Kansas to Lake Superior and then turn southward into central Michigan (Figures 1, 2). This system of anomalies clearly reflects major geological features, and as such it must represent a very significant episode in the history of the ...

The long-term radiological impact of underground disposal of vitrified HLW (high-level waste) resulting from different P&T strategies has been evaluated. The considered P&T strategies include recycling of Pu and Np in homogeneous mode and Am in heterogeneous mode in CAPRA reactors or EFRs (European Fast Reactor). The safety assessment has been performed for three different types of host rocks, ...

The Qinzhou Bay-Hangzhou Bay joint belt is a significant tectonic zone between the Yangtze and Cathaysian plates, where plentiful hydrothermal siliceous rocks are generated. Here, the authors studied the distribution of the siliceous rocks in the whole tectonic zone, which indicated that the tensional setting was facilitating the development of siliceous rocks of hydrothermal genesis. According...

Endothelial dysfunction is one of the main consequences of the toxic effects of cigarette smoke on the vascular system. Increasing evidence suggests that the small G-protein Rho-A and its downstream effectors, the Rho-kinases (ROCKs), are involved in systemic endothelial dysfunction induced by cigarette smoke. This study aimed to evaluate the role of the RhoA/ROCKs pathway in pulmonary artery e...
