Cytogenetic effects of the food preservatives — Sodium benzoate and sodium sulphite on Vicia faba root meristems
(1982-11)
Sodium sulphite and sodium benzoate induce in Vicia faba root meristems: (1) dose-dependent reduction in mitotic figures, (2) intact and severed anaphase bridges, (3) premature chromosome condensation heading to pycnofic ...
Resurfacing Saturn's Satellites: Models Of Partial Differentiation And Expansion
(University of Nairobi, 1985-12)
The faulting seen on the surfaces of Saturn's icy moons may have been caused either by external events, such as large impacts, or internal stresses caused by the expansion of the moons as long-lived radionuclides produced ...
Dielectric loss measurements on raw materials
(University of Nairobi,, 1980)
This paper describes a relatively simple experiment which can be performed by undergraduate students to study the dielectric properties of materials. Values of the dielectric loss tangent can be determined at low frequencies ...
The effect of temperature and gonadotropin on testicular steroidogenesis in Sarotherodon (tilapia) mossambicus in vitro
(University of Nairobi, 1983-04)
Testes of sexually mature Sarotherodon mossambicus were incubated at 15, 22, 30, and 40° with (a) tritiated testosterone and (b) salmon pituitary extract. Formation of 11-keto- and 11β-hydroxytestosterone from the tritiated ...
Species combination in tilapia culture
(University of Nairobi, 1982)
Preliminary determinations for the best species combination for the fastest rate of growth of Tilapia nilotica (Saro therodon niloticus) and T. zillii indicated that T. nilotica grew better (1.3 g/day) when raised with T. ...
Wax digestion by Black-throated Honey-guides Indicator indicator
(University of Nairobi, 1988-10)
The honey-guides (Indicatoridae) are brood parasites and specialist feeders on wax; the larger species obtain wax from bees' nests and the smaller ones from scale-insects or fruit (Friedmann 1955, Diamond 1985). The ability ...
