AIMS The aim of this research was to explore and capture complementary therapists' experiences of and preparation for working with patients in an acute cancer care setting. METHOD Semi structured interviews with therapists (n = 18) in an acute cancer hospital in the North West of England. The interviews were transcribed and analysed using thematic coding. RESULTS Key themes identified inclu...

Naturally occurring pores show a variety of polarities and sizes that are presumably directly linked to their biological function. Many biological channels are selective toward permeants similar or smaller in size than water molecules, and therefore their pores operate in the regime of single-file water pores. Intrinsic factors affecting water permeability through such pores include the channel...

We studied the response of Elaeagnus rhamnoides (Sea Buckthorn) to drought stress in a nursery. Photosynthesis and chlorophyll content under drought were change rather modest. Growth and physiological differences in response to drought were compared between four Sea Buckthorn seedlings treatments inhabited in the Qazvin provenance origin seeds in Mashhad city of Iran. The experimental design in...

Safflower having oil with high unsaturated fatty acids is a very valuable plant. However the sensitivity of safflower to some pests as safflower fly (Acanthiophilus helianthi), particularly in drought stress conditions has limited its production. In order to evaluate the effect of drought stress on population density and damage of important safflower pests, especially safflower fly, an experime...

We use classical atomistic molecular dynamics simulations of two water models (SPC/E and TIP4P/2005) to investigate the orientation and reorientation dynamics of two subpopulations of OH groups belonging to water molecules at the air/water interface at 300 K: those OH groups that donate a hydrogen bond (called "bonded") and those that do not (called "free"). Free interfacial OH groups reorient ...

[1] We performed triaxial compressive creep tests to study water weakening of clinopyroxenite in the diffusion creep regime. All tests were carried out on fine-grained samples at confining pressures between 100 and 300 MPa at temperatures of 1321 to 1421 K for water-saturated and 1398 to 1508 K for anhydrous conditions. Samples were prepared by hot-pressing ground powder of Sleaford Bay clinopy...

Rice is one of the most important food crops contributing over 39% of the total food grain production in China. Out of 113 million hectares of area sown under food crops 28% is covered by rice. The traditional irrigation regime for rice, termed as “continuous deep flooding irrigation” was applied in China before 1970s. A tremendous amount of water was used for the rice growing and only a low yi...

The temperature scale of simple water models in general does not coincide with the natural one. Therefore, in order to make a meaningful evaluation of different water models, a temperature rescaling is necessary. In this paper, we introduce a rescaling using the melting temperature and the temperature corresponding to the maximum of the heat capacity to evaluate four common water models (TIP4P-...

This is a study of the Euler equations for free surface water waves in the case of varying bathymetry, considering the problem in the shallow water scaling regime. In the case of rapidly varying periodic bottom boundaries this is a problem of homogenization theory. In this setting we derive a new model system of equations, consisting of the classical shallow water equations coupled with nonloca...
