Sericulture involves the rearing of silk-producing insects in captivity or collecting their silk cocoons in the field for production offabrics. The majority of the world’s silk is mulberry obtained from the domesticated silkworm, Bombyx mori L. (Lepidoptera:Bombycidae). Sericulture was formally introduced into Ghana in 1992 leading to the establishment of the Silk FarmersAssociation, and later a silk factory in 2002 with support from the FAO. This boost led to an increase in raw cocoon production,but is now dwindling due to numerous challenges facing the silk industry. A survey was carried out in the Eastern, BrongAhafo and Northern Regions of Ghana to establish the current status of sericulture. The survey revealed that farmers aremostly engaged in mulberry sericulture with wild silk being minimal, restricted to the rearing of the Eri silkworm, Philosamiaricini (Donovan) (Lepidoptera: Saturniidae) on castor oil and cassava leaves. Another important wild silkmoth, Gonometa sp.(Lepidoptera: Lasiocampidae) was found on Acacia sp. in northern Ghana. Brong-Ahafo region had the highest number ofsilk farmers. Farmers’ participation in sericulture has decreased over the years as a result of many setbacks. The prospectsand challenges confronting the sericulture industry in Ghana are discussed.

An examination of some specialized lunar and planetary ephemerides has revealed inconsistencies in the adopted planetary masses, the presence of non-gravitational terms, and some outright numerical errors. They should be considered of temporary usefulness only, subject to subsequent amendment as required for the interpretation of observational data.

Solid state x-ray sensing systems have been used for many years in conjunction with scanning and transmission electron microscopes. Such systems conveniently provide users with elemental area maps and quantitative chemical analyses of samples. Improvements on these tools are currently sought in the following areas: sensitivity at longer and shorter x-ray wavelengths and minimization of noise-broadening of spectral lines. In this paper, we review basic limitations and recent advances in each of these areas. Throughout the review, we emphasize the systems nature of the problem. That is. limitations exist not only in the sensor elements but also in the preamplifier/amplifier chain and in the interfaces between these components.Solid state x-ray sensors usually function by way of incident photons creating electron-hole pairs in semiconductor material. This radiation-produced mobile charge is swept into external circuitry by electric fields in the semiconductor bulk.
