Status of organochlorine (DDT) pollutants and steps toward electrocatalytic reductions
(University of Nairobi, 2001)
The accumulation of DDT in the environment over the years is a major concern in the world today. The extent to which DDT may be absorbed and translocated from 14C-p,p¢-DDT contaminated soils into cowpea plant tissues, and ...
A Synoptic Ecopath model of biomass flows during two different static ecological situations in Lake Nakuru (Kenya)
(2001)
Trophic relationships inside the Lake Nakuru ecosystem during two different phases are described by using the ECOPATH model. This allows a partial explanation of the ecological changes observed in the lake and to show that ...
Land-snail faunas of afromontane forests of Mount Kenya, Kenya: ecology, diversity and distribution patterns
(University of Nairobi, 2001-06)
Aims
To (1) describe the distribution patterns of land-snails occurring in afromontane forest habitats on Mount Kenya, in relation to elevation and aspect; (2) explore the relations between the land-snail faunas and ...

Solid-phase peptide synthesis of isotocin with amide of asparagine protected with 1-tetralinyl. Rifluoromethanesulphonic acid (tfmsa) deprotection, cleavage and air oxidation of mercapto groups to disulphide
(2001)
Isotocin, a nonapept ide amide, was synthesised on a benzhydryl-resin using the Bocst
rat egy. Benzyl group was used in the pr otect ion of the side-ch ains of tyrosine, ser ine and cyst eine.
Tetr alinyl group was used ...
Metallic Cu and In Films deposited by d.c. magnetron sputtering
(Kluwer Academic Publishers, 2001)
Cu and In fims have been deposited by direct current (d.c.) magnetron sputtering on glass
substrates under different deposition conditions. Deposition temperature, partial pressure in
the vacuum chamber, and thickness ...
Flavones and phenylpropenoids in the surface exudate of Psiadia punctulata
(University of Nairobi, 2001-06)
Three flavones, 5,7-dihydroxy-2′,3′,4′,5′-tetramethoxyflavone, 5,4′-dihydroxy-7,2′,3′,5′-tetramethoxyflavone, and 5,7,4′-trihydroxy-2′,3′,5′ -trimethoxyflavone were isolated from the leaf exudate of Psiadia punctulata, ...
Enhanced electro-detection of ascorbic acid in Adansonia digitata fruit by use of surface modified electrodes
(2001)
Surface modified electrodes have been used to study the seed of A. digitata. The results show the ascorbic acid redox peak is greatly enhanced and the oxidation/reduction peaks coincide with those of the corresponding ...
