Many countries have reported an increase in the death rate from bronchial asthma. Evaluation of the situation in Jamaica was undertaken to see if the trend is similar to that reported from elsewhere by analysing deaths for the period 1980 to 1989. There was an increase in the death rate during the period studied, most marked in females in rural areas. Most of the deaths occurred outside medical facilities. The reasons for these trends are not clear.

After oral doses to dogs of 14C-tinidazole, a 5-nitroimidazolyl antiprotozoal compound, a major and previously unidentified radioactive metabolite was isolated from urine and shown by FAB mass spectrometry and n.m.r. spectroscopy to be ring-hydroxylated. The exact identity of this metabolite was established by X-ray diffraction analysis as ethyl 2-(5-hydroxy-2-methyl-4-nitro-1-imidazolyl)ethyl sulphone. The apparent migration of the nitro group from the 5 position in the parent drug to the 4 position in the metabolite is a novel metabolic route.

The output irradiance of a typical unstable resonator with circular symmetry has a central obscuration and is peaked near the obscuration. A method is presented for designing two-mirror optical systems to convert this beam into a beam of arbitrary obscuration ratio and more uniform irradiance. A method is also given for analyzing the alignment sensitivity of such a system. An example shows that useful irradiance redistributions can be achieved with alignment sensitivities comparable to ordinary Cassegrain systems.
ABSTRACT
For precision optical systems, the focus and tilt errors caused by coating thickness nonuniformity can be a serious concern. These errors are wavelength dependent and hence cannot be compensated in an IR optical system by aligning and focusing with an auxiliary visible alignment laser. It is shown here that the coating design can be modified so as to make the aberrations caused by coating thickness nonuniformity approximately equal at the IR design wavelength and the wavelength of the auxiliary laser. In that case, focusing and alignment with an auxiliary laser can substantially correct the effect of coating nonuniformity.
