Assessment of organochlorine pesticides (OCPs) contamination in relation to physico-chemical parameters in the Upper River Kuja Catchment, Kenya (East Africa)
(International Journal of Fisheries and Aquatic Studies, 2018-12)
Concentrations of 17 organochlorine pesticides residues (alpha-HCH, beta-HCH, gamma-HCH, deltaHCH, Heptachlor, Aldrin, Endrin, Endosulfan I, Dieldrin, p,p’-DDT, Endosulfan II, p,p’-DDD, Endrin
aldehyde, p,p’-DDE, Endosulfan ...
Nonlinear H∞ Guidance Design for Missile against Maneuvering Target
(Science Domain, 2017-05-01)
A new guidance law is derived for missile against maneuvering target by adopting nonlinear H∞ control theory. The guidance law is based on three dimension (3D) nonlinear kinematics described by modified polar ...
Trace Metal Detection in Aqueous Reservoirs Using Stilbene Intercalated Layered Rare-Earth Hydroxide Tablets
(Hindawi, 2020-03-30)
Contamination of aquatic reservoirs with metal ions is a slow gradual process that is not easy to detect. Consequences of the metal ions, especially the ones with high atomic numbers (heavy metals) at high concentrations, ...
Layered Rare-Earth Hydroxide Unilameller Nanosheets: Synthesis, Characterization, and Adsorption
(Hindawi, 2020-01-28)
Unilameller nanosheets with a lateral dimension of one nanometer have been isolated from a colloidal solution of europium-containing layered rare-earth hydroxide (LRH) material by the flocculation method. The nanosheets ...
GBS Mapping and Analysis of Genes Conserved between Gossypium tomentosum and Gossypium hirsutum Cotton Cultivars that Respond to Drought Stress at the Seedling Stage of the BC2F2 Generation
(Multidisciplinary Digital Publishing Institute, 2018-05-30)
Cotton production is on the decline due to ever-changing environmental conditions. Drought and salinity stress contribute to over 30% of total loss in cotton production, the situation has worsened more due to the narrow ...
Mathematical Modelling of the COVID-19 Pandemic with Demographic Effects
(Springer Nature, 2021-03-17)
In this paper, a latent infection susceptible–exposed–infectious–recovered model with demographic efects is used to understand the dynamics of the COVID-19 pandemics. We calculate the basic reproduction number (R0) by ...
On Centre Properties of Irreducible Subalgebras of Compact Elementary Operators
(doi:10.30538/psrp-oma2020.0065, 2020)
In this paper, we characterize the centre of dense irreducible subalgebras of compact elementary operators that are spectrally bounded. We show that the centre is a unital, irreducible and commutative C∗ -subalgebra. ...
Effects of Colchicine Treatments on Chromosome Doubling in Three Diploid Cotton Species
(Journal of Multidisciplinary Engineering Science and Technology, 2017-04-04)
Colchicine has been used to induce chromosome doubling in plant species. Diploid cotton species have inherited desirable genes that are resistant to biotic and abiotic stresses and also possesses useful fiber quality traits, ...
The Role of Bio-Extracted Reduced Graphene Oxide in the Crystallization Kinetics of Chitosan Bio-Polymer
(Scientific research and community, 2021-01-29)
Carbon nanomaterials have recently attracted wide scientific applications due to their tunable properties. These novel materials act as best fillers that can provide substantial benefits due to their high strength, thermal ...
On Norm Inequalities and Orthogonality of Commutators of Derivations
