Technical assessment of three layered cement-bonded boards produced from wastepaper and sawdust.

The technical properties of three layered cement-bonded boards (CBBs) made from wastepaper and sawdust were investigated. The CBBs were produced at three density levels of 1000, 1200 and 1300 kg/m3 and at four cement/particle ratios of 2.0:1, 2.

Association between duration of humid season and geographical distribution patterns of different species of chewing lice (Mallophaga:Insecta) infesting domestic chickens in Nigeria.

In a countrywide study of the geographical distribution patterns of chicken lice in Nigeria, 3 species, Menacanthus pallidulus (Neumann 1912), Goniodes dissimilis Denny, 1842, and Menopon gallinae (Linnaeus, 1758), were completely restricted to within areas with a long humid season (6-12 humid mo per yr). In constrast, 4 species, Cuclotogaster occidentalis Tendeiro, 1954, Menacanthus cornutus (Schommer, 1913), Amyrsidea powelli (Bedford, 1920), and Goniodes gigas (Taschenberg, 1879), thrived only in areas where the humid season was of a short duration (< or = 5 mo). The last 3 named species extended also into the fringes of areas with a long humid season (6-8 humid mo) at significantly reduced numbers.
