Speed as a crucial phenomenon of modernism affects individual and collective life of human being and changes the traits of the places people live in. Increasing speed is the demand of the modern era, though on the other side in recent years there is a contrary incline towards slowing down different aspects of life. In view of this, the dualities in between social features of Speed up and slow d...

A heat-conditioning treatment of 10 mm at 45°followed by 370 incubation resulted in maximal thermotolerance 8 hr later. The D@of the heat survival curve increased from 4.5 mm (control) to 19.8 mm at 45°.Two heat-conditioning treatments (10 mm at 45°+ 4 hr at 37°+ 15 mm at 45°)resulted in a higher thermotolerance maximum (D@= 26.7 mm) 8 hr after the second • conditioning treatment. In com...

The decision of the embryonic gonad to differentiate as either a testis or an ovary is a critical step in vertebrate development. The molecular basis of this decision has been the focus of much study, particularly over the past decade. Here we contrast the knowledge of early gonadal development and the switch to testis differentiation with the lack of molecular understanding of ovarian developm...

Vitrectomy was performed bilaterally in pigmented rabbits and followed by silicone oil injection in one eye only. Electroretinographic studies were performed preoperatively and at selected postoperative intervals. In the early postoperative period both eyes showed an initial reduction in a and b wave amplitudes, followed by a return to baseline values. The amplitudes were symmetrically and equa...

After 18 weeks of a controlled comparative study of extended contact lens wear a male subject presented with ocular symptoms. Microepithelial cysts were observed in both eyes and, after examination, in the eyes of 44 other participating patients. The cysts have been photographed and the rate of recovery monitored.

A large- or full-field visual stimulus slowly rotating around the naso-occipital axis of an observer causes both eyes to tort, and many of the factors controlling this optokinetic torsional response have been identified. The present study reports that a single line rotating about the line of sight can cause both eyes to tort in the same direction as the stimulus but with a low gain. We have use...
