in this note we review a simple criterion, due to ekedahl, for superspecial curves defined over finite fields.using this we generalize and give some simple proofs for some well-known superspecial curves.

The secrecy capacity of a discrete memoryless Gaussian Wire-Tap Channel when the input is from a finite complex constellation is studied. It is shown that the secrecy capacity curves of a finite constellation plotted against the SNR, for a fixed noise variance of the eavesdropper’s channel has a global maximum at an internal point. This is in contrast to what is known in the case of Gaussian co...

Abnormalities of lung function in 92 children with idiopathic or congenital scoliosis are described. The changes are restrictive in type with reduction in vital capacity and total lung capacity but normal residual volume. In children whose curves had an early onset, the amount by which vital capacity was reduced depended on the severity of the deformity; in those whose curves began in adolescen...

in this study, functional properties of red bean, chickpea, lentil and canellini bean were evaluated. our results revealed that beans had the highest emulsifying capacity. this property was minimum at the isoelectric point (about 4) among all samples which is in concistent with their solubility curves. salt concentration of 0.5 m did not have a significant influence on emulsifying capacity but ...

One of the serious damages of tremendous earthquakes is the damage to bridges as the major components in an    arterial road network, as relief operation is interrupted following cutting roads. Regardless of the magnitude and severity of an earthquake, other factors are also important in the strength and seismic performance of concrete bridges. Freezing-thawing cycles are among the factors, whi...

1. Forced exhalations performed from volumes below total lung capacity, so-called partial expiratory flow-volume curves, are suggested to be more sensitive in detecting airways bronchoconstriction than maximal expiratory flow-volume curves begun at total lung capacity. 2. In eight healthy men both maximal and partial expiratory flow-volume curves were measured where breath was held at total lun...

in this study the thermal conductivity and the volumetric heat capacity of non-newtonian fluids are investigated. these fluids find many applications in chemical, medical and food industries. they mostly have viscoelastic behavior and generally differ from newtonian fluids. two non-newtonian fluids, solutions of xanthan and carboxy methyl cellulose in water with various concentrations have bee...

Fourteen subjects showing an increase of residual volume (RV) without any clinical or functional signs of bronchial obstruction were studied. Maximum expiratory flow volume (MEFV) curves were obtained with a pressure-corrected volume plethysmograph. Static pressure-volume curves were obtained by stepwise interruption of a slow expiration from total lung capacity (TLC) to RV. Static compliance w...
