Classifying Two-dimensional Hyporeductive Triple Algebras
Two-dimensional real hyporeductive triple algebras (h.t.a.) are investigated.
A classification of such algebras is presented. As a consequence, a
classification of two-dimensional real Lie triple algebras (i.e. generalized
Lie triple systems) and two-dimensional real Bol algebras is given.Comment: 12 pages; 0 figur
Hom-Akivis algebras
Hom-Akivis algebras are introduced. The commutator-Hom-associator algebra of
a non-Hom-associative algebra (i.e. a Hom-nonassociative algebra) is a
Hom-Akivis algebra. It is shown that non-Hom-associative algebras can be
obtained from nonassociative algebras by twisting along algebra automorphisms
while Hom-Akivis algebras can be obtained from Akivis algebras by twisting
along algebra endomorphisms. It is pointed out that a Hom-Akivis algebra
associated to a Hom-alternative algebra is a Hom-Malcev algebra.Comment: 15 pages, 0 figure, a section and references are adde

Effects of some environmental factors on the fecundity of Tilapia species (Family Cichlidae) in Kigera Reservoir, New Bussa
The effects of some environmental factors on the fecundity of Tilapia species (Family Cichilidae) was carried out at the Kigera dam. Four Tilapia species caught were Tilapia zilli, Hemichromis fasciatus, Sarotherodon galilaeus and Oreochromis niloticus while the environmental factors considered were water temperature, Dissolved Oxygen, pH value, level of rainfall and rate of sunshine and range of time. 43 fish comprising of 25 male with (58.1%) and 18 females having (41.9%) were studied with 74.42% been sexually matured. Both high levels of rainfall and dissolved oxygen favoured fecundity. The spawning peak occurred in (July), environmental factors monitored indicated that dissolved oxygen ranges from 3.7 to 4.45mg/lit rainfall ranges from (34.90mm to 237.80mm) sunshine ranges from (5hrs-8hrs) and pH ranges from (7.35-7.45). The spawning of these species in their natural or hatchery condition is therefore best achieved during the peak of raining seaso
