RELATION BETWEEN GLOBAL RADIATION AND FOOD PRODUCTION IN A HUMID TROPICAL CLIMATE OF WEST AFRICA

Obvious is the fact that globally the climate is changing. Solar energy and water availability are the key factors affecting agricultural productivity in Subtropical Africa. In this paper is presented the global radiation for Owerri, Nigeria (latitude 5.48oN, longitude 7.03oE) between 1985-1997 which has a mean annual value of 76.17 W/m2 per day. With appropriate crop specie selection and management, food production, including poultry output can be boosted in this high solar radiation area. The introduction of solar egg incubator, solar manure dryer and brooder has been strongly advocated

Retained Surgical Instruments in The Pelvis Complicated by Colo-vesical Fistula

Retaining a surgical instrument in the patient unintentionally could lead to serious complications and in extreme cases, death. It also damages the reputation of the healthcare provider, as well as the health facility involved. We report a case of retained haemostat and dissecting forceps complicated by colo-vesical fistula 10 years after hysterectomy in a 50-year-old lady with a 7-month history of passage of urine per rectum. The foreign bodies were removed as well as an associated bladder calculus. The fistulae were repaired and recovery was uneventful
