An electron density map at 3 angstrom resolution has been calculated for Cu2+, Zn2+ superoxide dismutase from bovine erythrocytes, and the course of main chain traced. The dominant structural feature is an 8-stranded barrel antiparallel beta-pleated sheet. There one very short helical section two long loops non-repetitive structure. Cu Zn are bound between side beta about 6 Angstrom apart, with a common histidine ligand. four ligands in somewhat distorted square plane, three histidines...

The published correlations for the drag force on a sphere moving in fluid have been critically examined and their limitations identified. A series of new has proposed, each covering wide range particle Reynolds number Re(10−2< Re < 3 × 105) by choice appropriate form iterative calculations can be avoided.

Abstract The published correlations for the velocity-voidage relationship observed during fluidization and sedimentation of uniformly sized spherical particles in solid-liquid systems are compared with experimental results. It is found that expression suggested by Richardson Zaki represents data well over a wide range values Galileo number (10−2 < Ga< 1010) voidage (0·4 ϵ 1). Methods given predicting constants as function properties system, including wall effects. KEYWORDS: Fluidized...

Although disasters are a major cause of mental health problems and typically affect large numbers people communities, little is known about how social structures after disaster. The authors assessed the extent to which outcomes disaster associated with network structures.In community-based cohort study survivors bushfire disaster, participants (N=558) were for probable posttraumatic stress disorder (PTSD) depression. Social networks by asking nominate whom they felt personally close. These...

Natural disasters represent an increasing threat both in terms of incidence and severity as a result climate change. Although much is known about individual responses to disasters, less the social contextual response how this interacts with trajectories mental health, wellbeing connectedness. The 2009 bushfires Victoria, Australia caused loss life, property destruction, community disturbance. In order progress future preparedness, recovery, it crucial measure understand impact at levels....

Disasters pose a documented risk to mental health, with range of peri- and post-disaster factors (both pre-existing disaster-precipitated) linked adverse outcomes. Among these, increasing empirical attention is being paid the relation between disasters violence.This study examined self-reported experiences assault or violence victimisation among communities affected by high, medium, low disaster severity following 2009 bushfires in Victoria, Australia. The association violence, health...
