The improving effect of rate promoters has been investigated by experiments at pilot plant scale in conditions close to the operating conditions of the top zone of a typical hot potassium carbonate industrial packed bed absorber. The evaluation of promoter enhancement factor has been done by successive experiments with absorption of CO2 into water, into carbonate solution and into promoted carb...

Many eurythermal organisms alter composition of their membranes to counter perturbing effects of environmental temperature variation on membrane fluidity, a process known as homeoviscous adaptation. Marine intertidal gastropods experience uniquely large thermal excursions that challenge the functional integrity of their membranes on tidal and seasonal timescales. This study measured and compare...

There are four different stable climate states for pure water atmospheres, as might exist on so-called "waterworlds." I map these as a function of solar constant for planets ranging in size from Mars-sized to 10 Earth-mass. The states are as follows: globally ice covered (Ts ⪅ 245 K), cold and damp (270 ⪅ Ts ⪅ 290 K), hot and moist (350 ⪅ Ts ⪅ 550 K), and very hot and dry (Tsx2A86;900 K). No st...

Hot tearing: from organic alloys to superalloys. The appearance of solidification cracks or hot tears during casting is a serious defect. EPF-Lausanne has developed a criterion for the appearance of hot tears which is based upon a mass balance performed over the liquid and solid phases and which takes into accounts for the tensile deformation of the solid skeleton perpendicular to the growing d...

The in vitro antimicrobial activity of Sapindus mukorossi and Emblica officinalis fruit extracts were studied against Streptococcus mutans, Staphylococcus aureus, Lactobacillus acidophilus, Candida albicans and Saccharomyces cerevisiae. The acetone, ethanol, methanol, hot water and cold water extracts of S.mukorossi exhibited antimicrobial activity against one of the tested microorganisms i.e. ...

Two important factors affecting hot tearing – semi-solid constitutive behaviour and grain percolation – have been simulated through the use of microstructure models based on granular structures. The semi-solid model geometry is based on a modified Voronoi tessellation, and includes rounded corners to approximate an equiaxed-globular grain structure with liquid surrounding the grains. The percol...

Menopause is coincident with ovarian failure in women, resulting in a relatively rapid fall in levels of estrogens. Although there is no comparable hormonal event in men, some do have hot flashes. In Sweden, it was found that 33.1% of noncastrated men reported hot flashes [1]. The underlying mechanisms for this are not known. In women, hot flashes are the most common symptom of menopause and ar...

the present research article highlights the metal (cd, cu, pb, zn and fe)distribution pattern in the rspm generated in different hot spot sites located at kochi, thequeen of arabian sea. these sampling sites are categorized under three different zonesas estuarine, riverine, and coastal. two sampling phases are selected in order to check theconsistency in pollution trend after a two year gap and...

Experiments were performed with the aim of investigating the effect of season on haematological parameters and erythrocyte osmotic fragility (EOF) of pigs. A total of 23 local pigs including males, non-pregnant and non-nursing females, aged 9 to 12 months were used for the study, ten animals were used during the hot-dry season and thirteen during the harmattan season. Blood sample was taken fro...
