For a photon field of size 20x20cm in a telecobalt machine with ‘Source Diaphragm Distance (SDD)’ of 45 cm, DWTC is designed to provide compensation at ‘source skin distance (SSD)’ of 80 cm. A jig stand with 3 acrylic perforated sheets kept together at specified gaps allow required radial divergence of the metal spokes on equally spaced grid. Dose compensator could be fabricated by a tray mount...

Since its introduction in 1940, the plaster of Paris block method of measuring soil moisture by means of electrical resistance (4) has been widely employed in agricultural fields. Hydrologic research2 (16), war production problems involving guayule culture (11, 12), and many other investigations ranging from field irrigation to greenhouse studies have made use of this technique. Briefly, the me...

There is debate about the most appropriate form of treatment for partial tears of the lateral ligament of the ankle, which are common after inversion injuries. A prospective trial of four forms of treatment was carried out. The forms of treatment used were: no treatment with only a minimal bandage, Tubigrip support, immobilisation in plaster-of-Paris, and physiotherapy. The end point was taken ...
