BACKGROUND The large majority of people with dementia receive nothing in the way of specialist assessment and care at any stage of their illness. There is a particular lack of services focussed on early identification and intervention in dementia where there is the possibility of long-term harm reduction for people with dementia and their family carers. We have developed a model of care that is...

One alternative for the storage and transport of hydrogen is blending a low amount (up to 15 or 20%) into existing natural gas grids. When demanded, can be then separated, close end users using membranes. In this work, composite alumina carbon molecular sieves membranes (Al-CMSM) supported on tubular porous have been prepared characterized. Single permeation studies showed that H2/CH4 separatio...

Early life experiences are likely to be important for the formation of preferences. Religiosity is a key dimension of preferences, affecting many economic outcomes. This paper examines the effect of college major on religiosity, and the converse effect of religiosity on college major, using panel data from the Monitoring the Future survey as a way of gauging the extent to which various streams ...

The Shanker distribution, a one-parameter lifetime distribution with an increasing hazard rate function, is recommended by for modelling lifespan data. In this study, we examine the theoretical and practical implications of 2-component mixture model (2-CMSM). A significant feature proposed model’s function that it has rising, decreasing, upside-down bathtub forms. We investigate statistical cha...

Carbon membranes are a potentially attractive candidate for the in-situ removal of water vapor in CO2 hydrogenation reactions. Their hydrophilicity and pore structure can be tuned by properly adjusting synthesis procedure. Herein, we assess effect carbonization temperature (450–750 °C) on performance supported CMSM terms vapor/gas separation, correlation with changes their surface functionality...

Testing the Weak Equivalence Principle (WEP) to a precision of $10^{-15}$ requires quantity data that give enough confidence on final result: ideally, longer measurement better rejection thestatistical noise. The science sessions had duration 120 orbits maximum and were regularly repeated spaced out accommodate operational constraints but also in order repeat experiment different conditions all...

Carbon molecular sieve membranes (CMSMs) have been considered as very promising candidates for gas separation, in terms of separation properties as well as thermal and chemical stability. Due to the numerous advantages and wide applications of carbon membranes, their application for gas separation is of special importance. Because of the importance of carbon membranes and a large number of stud...

The separation of H2O vapor from (hydrogen-rich) gaseous streams is a topic increasing interest in the context CO2 valorisation, where situ water removal increases product yield and catalyst stability. In this work, composite alumina carbon molecular sieve membranes (Al-CMSM) were prepared phenolic resin solutions loaded with hydrophilic boehmite (γ-AlO(OH)) nanosheets (0.4–1.4 wt. % solution) ...

We report vibrational branching ratios for resonant photoionisation of N2 leading to the X *E; state of N:. Our theoretical values are obtained from an accurate solution of the adiabatic-nuclei frozen-core Hartree-Fock model of molecular photoionisation. In contrast to other theoretical results the present results are in very good agreement with experimental measurements. Differences between th...
