A subalgebra $B$ of a Lie algebra $L$ is called weak c-ideal if there subideal $C$ such that $L=B+C$ and $B\cap C\leq B_{L} $ where $B_{L}$ the largest ideal contained in $B.$ This analogous to concept weakly c-normal subgroups, which has been studied by number authors. We obtain some properties c-ideals use them give characterisations solvable supersolvable algebras. also note one-dimensional ...

We prove that if A is a C-algebra, then for each a ∈ A, Aa = {x ∈ A/x ≤ a} is itself a C-algebra and is isomorphic to the quotient algebra A/θa of A where θa = {(x, y) ∈ A×A/a∧ x = a∧ y}. If A is C-algebra with T , we prove that for every a ∈ B(A), the centre of A, A is isomorphic to Aa ×Aa′ and that if A is isomorphic A1 ×A2, then there exists a∈ B(A) such that A1 is isomorphic Aa and A2 is is...

Freshly harvested tomato fruit (Solanum lycopersicum) were pre-treated with 0, 50, and 100 µM prohexadione-calcium (Pro-Ca) and then stored at 1 °C for 21 days to investigate the effect of Pro-Ca treatment on electrolyte leakage (EL), malondialdehyde (MDA), proline and total phenols contents, and activity of phenylalanine ammonia-lyase (PAL) in relation to chilling injury (CI).Treatment with Pr...
