Three types of filters, silver, polycarbonate, and cellulose, were evaluated for permeability toward poliovirus suspended in water, salt-containing, and proteinaceous solvents. The ability of virus to pass through cellulose filters depended on the suspending medium; virus did not pass through cellulose filters in either water or salt solution, whereas the use of protein solutions increased filt...

1. Blood rheology has been quantified by measuring blood and plasma viscosity, packed cell volume (PCV), erythrocyte filterability and erythrocyte aggregation in forty-eight voluntary vegetarians and compared with matched controls. 2. Results show that in vegetarians, values for PCV were lower than those in controls, leading to reduced native blood viscosity. In addition PCV-standardized blood ...

Red cell acetylcholinesterase (AChE) and Na, + K ~adenosinetriphosphatase (ATPase) activities, cell 2,3 diphosphoglycerate (2,3 DPG) and adenosinetriphosphate (ATP) content and filterability ratio were studied in two children (with moderate hemolytic anemia and marked spherocytosis) and their parents. Patients’ parents have no medical problem but evidenced discrete spherocytosis on peripheral s...

Haematological and rheological (plasma and serum viscosity, whole blood viscosity, and erythrocyte filterability) factors were studied in 31 age-sex matched pairs of patients with sickle cell haemoglobin C disease with and without proliferative sickle retinopathy (PSR). Patients with PSR had significantly higher mean cell haemoglobin and lower Hb F levels on average than the matched controls, b...

While most masks have a limited effect on personal protection, how effective are they for collective protection? How to enlighten the design of from perspective dynamics? In this paper, we assume three preferences in population: (i) never wearing mask; (ii) mask if and only infected; (iii) always mask. We study epidemic transmission an open system within Susceptible-Infected-Recovered (SIR) mod...

Acetone organosolv fractionation of beech and birch wood at the lab-scale results in high sugar yields from (hemi)cellulose isolation a high-purity lignin. In this study, process is scaled up to validate technology pilot scale using industrial-size chips low liquid-to-solid ratios as next step toward commercialization. Translation pilot-scale showed similar performance compared processing with ...
