The measurement of activity due to the naturally occurring radionuclide has been carried out in different brands of cement available in Pakistan. The gamma spectra of the collected samples were obtained using high-purity germanium detector and analysed for the presence of 232Th, 238U and 40K. The assessment of radiological hazards due to these radionuclides(More)
The objective of this study was to investigate the effect of upper limb postures on discomfort by repetitive gripping tasks. In the present experiment, the three levels of the upperarm abduction angle (0 degrees, 45 degrees, and 90 degrees) with three levels of the elbow flexion angle (45 degrees, 90 degrees, and 135 degrees) were taken as independent(More)
5g~ 5g~ v ~ 4 sacs are si tuated along the ovule axis. The embryo sac at the micropylar end is a t the 3-nucleate stage and the one si tuated below it, a t the 8-nucleate stage. Organization of three antipodal cells has taken place in the lower sac, while its micropylar end has four nuclei and one prominent cell (probably the egg). Synergids are absent(More)
OBJECTIVES To investigate the effects of upper limb postures on discomfort score for repetitive gripping task. PARTICIPANTS Eighteen right handed male participants volunteered in the experimental investigations. METHOD The present study was divided into two experiments. A Full factorial design of 2 (Two shoulder rotation angles) × 3 (Three elbow flexion(More)
Straight crosscountry pipelines are supported throughout the length of pipeline on different forms of supports at more or less regular spans. Maximizing the distance between supports will minimize the number of supports required, which in turn reduce the total cost of erecting these pipe supports. ASME has suggested the standards for support span, but the(More)
This experiment was designed to know the effect of upper limb postural deviations on grip strength and grip endurance time. A full factorial design of experiment, i.e., 3 (0°, 45°, 90° abduction angles of upper arm) × 3 (45°, 90°, 135° angles of elbow flexion) × 3 (0°, -60° prone, +60° supine angles of forearm rotation) was used to find the effect of 27(More)

Workers whose hands are regularly exposed to hand-arm vibration may suffer from damage to the tissues of the hands and arms, which cause the symptoms collectively known as hand-arm vibration syndrome. However, investigations have shown that vibration hazards can be controlled and risks might be reduced by good design of the task/tools. In the present study,(More)
