The rate of calcification of new bone (accretion rate) was measured by a radioisotope technique in 20 patients with carcinoma of the breast, 14 patients with multiple myelomatosis, five patients with Paget's disease of bone, and in six patients with solitary, non-osseous tumours. The rate of bone destruction was assessed in these patients by the measurement of the rate of urinary calcium excret...
The removal of nitroaromatics from polluted water is difficult due to their high stability to conventional treatment methods. This paper presents a method for the destruction of 1,3-dinitrobenzene and 2,4-dinitrotoluene in aqueous solutions. The compounds are shown to be stable to reaction with ozone, even under ultrasonic activation. The use of ultrasound enhances the rate of electrochemical r...
Previous investigations (Kinsloe et al., 1954) of the effect of time, pH, temperature and acoustic field on the destruction of microorganisms by vibratory energy showed the destruction to be due largely to mechanical breakdown and that the rate of destruction was dependent on the acoustic field. The objectives of the present study include a comparisoii of the effect on microorganisms of a focus...

A few previous studies have dealt with some aspects of this entity among Nigerians with pulmonary tuberculosis but these studies may not truly reflect its current trends. OBJECTIVE To describe the presenting profiles and outcome of unilateral tuberculou...
