A system for automated chromosome analysis

Summary A new method for automated chromosome analysis is presented. This makes use of both a pen reader and trained observer, and allows a more flexible approach than hitherto.     

The anatomy of Microplana termitophaga from Zimbabwe and Kenya: confirmation of the subfamily and genus

Microplana termitophaga has been observed feeding on termites in Harare, Zimbabwe. In small specimens the pharynx is about two-thirds of the way along the body, but in large specimens the pharynx is only one quarter of the way along the body. Details of the subepidermal musculature of specimens from Kenya and Zimbabwe are described which confirm the previously uncertain assignment of the species to the subfamily Microplaninae. Sexually mature specimens are found towards the end of the wet season in Zimbabwe. The anatomy of the reproductive system is described. The gonopore is about two-thirds of the way along the body in mature specimens, but sexual maturity seems not to be related simply to size. There is a genito-intestinal duct which confirms that the species is of the genus Microplana.     

Endurance Fitness and a Home Exercise Program in College Girls

College girls exercising at home for 19 minutes daily using the 10BX Royal Canadian Air Force exercise plan, with the addition of rope skipping, improved their physical working capacity and maximal oxygen uptake by 7 and 9% after six weeks. No change occurred in a matched control group. Changes in endurance fitness with this type of training are of relatively small magnitude, and reproducible measurements are required for their demonstration. The small gains in aerobic power would seem to be of little practical significance for the subjects, and a major drawback of any home exercise program is the lack of motivation to continue.
