This study explores the effect of Ag+ ions on transient photoconductivity of thin films of Se75Te20Ag5. The thin films of Se75Te20Ag5 chalcogenide alloys were made by evaporation method using a vacuum chamber at HBTI Kanpur, India. This amorphous system showed the presence of negative photocurrent when white light was stopped showing on the sample. The rise and decay of photoconductivity was ob...

Section 7.2 – EFFECTS OF AGE ON OPERATIONAL PHYSICAL PERFORMANCE

Age is widely regarded as the most important determinant of the loss of an individual’s physical performance capability over time. Said loss is of concern for employers of personnel involved in physically demanding occupations, particularly military personnel. A minimum level of physical performance is a prerequisite for military personnel because the absolute physical job demands are often dic...

ALLERGIC DERMATOSIS AND URTICARIA (J RING, SECTION EDITOR) Physical Urticaria

The physical urticarias are a heterogeneous subgroup of chronic urticarias in which wheals can be reproducibly induced by different specific physical stimuli such as cold, heat, pressure, vibration, or sunlight. Physical urticarias comprise up to 25 % of chronic urticarias and occur more frequently in young adults. Symptoms, i.e. wheal and flare responses or angioedema, are usually limited to t...

The Study of Inlet Section on Flow Hydraulics in Zigzag-Morning Glory Spillways with Physical Modelling

Morning glory spillway is one of the spillways that used to passing of flood from high to low level. This spillway is used in the reservoir dams that are placed in narrow valleys and in many locations with high slope in reservoir walls. In the Morning glory spillways, the vortex flow can reduce discharge, discharge coefficient and the performance of spillway. The zigzag spillway, as another typ...
