The solubility of the spin label TEMPO (I) in membranes depends on the fluidity of the membrane. An empir ical relat ionship has been establ ished between TEMPO solubility and fluidity, measured by the order parameter S~o. This relationship is employed to determine the fract ion of the lipid in membranes of rabbit muscle sarcoplasmic re t iculum that is in a fluid state. We find that 84% of the...

During the course of this project dCSE Fluidity-ICOM has been transformed from a code that was primarily used on institution level clusters with typically 64 tasks used per simulation into a highly performing scalable code which can be run efficiently on 4096 cores of the current HECToR hardware (Cray XT4 Phase2a). Fluidity-ICOM has been parallelised with MPI and optimised for HECToR alongside ...

The influence of lindane (gamma-hexachlorocyclohexane) on fluidity of plasma membranes from rat renal cortical tubules has been investigated. Preincubation with lindane increased membrane fluidity. This effect was accompanied by (i) a decrease in the transport of glucose with regard to the controls and (ii) an inhibition of the beta-adrenergic stimulatory activity upon cyclic AMP accumulation. ...

In the preceding paper (1b) a formula was developed for the lowering of the fluidity of a medium by a mixture of proteins, given the volume concentration of each and its fluidity-lowering constant. Whole blood is now shown to follow an essentially similar formula, except that the hemoglobin content is taken from the literature as the best available measure of the volume of the blood cells Delta...

Slack resources have important strategic and managerial implications in an organization and IT plays an important role in redeploying them. Yet, this area has largely been overlooked by the IS community. This study, through a novel theoretical lens of resource fluidity, aims to answer how organizations leverage IT to redeploy slack resources. We conduct a case study at two leading manufacturers...

We study the internal dynamical processes taking place in a granular packing below yield stress. At all packing fractions and down to vanishingly low applied shear, a logarithmic creep is observed. The experiments are analyzed using a viscoelastic model which introduces an internal, time-dependent, fluidity variable. For all experiments, the creep dynamics can be rescaled onto a unique curve wh...

Blood fluidity in the capillaries is affected significantly in diseases such as cardiac and brain infarcts, diabetic gangrene and many others. In view of the importance of physiology and pathology of capillary circulation, the hemorheological characteristics of the capillary blood flow are discussed in this article. Also, a new diagnosing technique for blood fluidity disorders is proposed. A co...

This annotated bibliography focuses on issues of power, participation and governance in relation to Somali networks. There is a healthy body of academic literature examining Somali social structures, including networks and clans. Specific detail on the power relations and differentials between and within clans, however, is scarce. Experts attribute this lack of knowledge to the complexity and f...

Using the spin label method (ESR) it has been shown that biologically active, amphiphilic compounds (quaternary ammonium salts (AS) containing polar heads with single and double positive charge caused, at low concentrations, decrease fluidity of liposome membranes formed with egg yolk lecithin (EYL). At higher concentrations an increase in fluidity was observed. With compounds having a single p...
