SINCE the cytology service was begun in this area cervical smears have been taken routinely at postnatal and gynaecological clinics. Positive smears thus obtained have been purposely excluded from the present series which refers only to asymptomatic women. Initial requests to practitioners to refer such patients met with a very disappointing response and it was decided to begin an organised pro...
متن کاملExtraction of alumina from clays and high-silica bauxites.
Two processes for extracting alumina from low-grade ores are described, one applicable to both clays and high-silica bauxites, and the other only to bauxites. In the former process, a line-containing sinter is prepared and annealed by cooling it slowly through the range of 1,3000 to 1,2000 C. The annealed sinter dusts to a powder which requires no grinding. This material is extracted with a sol...
متن کاملA Case of Hydatid Cyst in County Antrim
HYDATID disease is due to the development in man, acting as an intermediate host, of the cystic larval form of a small tapeworm, Echinococcus granulosus, the normal habitat of which is the ileum of the dog. Ova from an infected dog are deposited with its faeces on the ground. By this means grass and vegetables are polluted with ova, and when eaten by sheep, cattle, goats or occasionally by man ...
متن کاملAnalysis of ASTER data for mapping bauxite rich pockets within high altitude lateritic bauxite, Jharkhand, India
Bauxite deposits of Jharkhand in India are resulted from the lateritization process and therefore are often associated with the laterites. In the present study, ASTER (Advanced Space borne Thermal Emission and Reflection Radiometer) image is processed to delineate bauxite rich pockets within the laterites. In this regard, spectral signatures of lateritic bauxite samples are analyzed in the labo...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
