The groundnut leafminer (Aproaerema modicella), has been reported from east African countries since 1998 and from South Africa since 2000. The study aimed at determining the biology and management of groundnut leafminer (GLM) in South Africa. In a survey, 10 parasitic Hymenoptera species were identified. Two hyperparasitoids were also recorded for the first time in South Africa. GLM flight acti...

Hemi-pyocyanin (HPC) is a heterocyclic nitrogenous compound with some reported potential medical effects. The current report aimed to investigate the use of organic industrial waste for production HPC via microbial fermentation. novel antidiabetic activity was also accessed and in this work. A peanut oil processing by-product (groundnut cake) screened as best substrate Pseudomonas aeruginosa TU...

We provide an ex-post econometric examination of the harmonization and tightening of the EU Maximum Residues Limit (MRL) on aflatoxins in 2002, and its impact on African exports of groundnut products. We show that the MRL set by the EU has no significant trade impact on groundnut exports from Africa across various methods of estimation. African domestic supply plays an important role in the det...

Groundnut (Arachis hypogaea L.), a self-pollinated legume is an important crop cultivated in 24 million ha world over for extraction of edible oil and food uses. The kernels are rich in oil (48-50%) and protein (25-28%), and are source of several vitamins, minerals, antioxidants, biologically active polyphenols, flavonoids, and isoflavones. Improved varieties of groundnut with high yield potent...

The effect of groundnut oil on blood glucose, lipid profile, lipid peroxidation, and antioxidant status in streptozotocin-diabetic rats was investigated and compared with diabetic and drug-treated rats. Diabetes was induced in adult female Wistar rats by intraperitoneal administration of streptozotocin (40 mg/kg b-wt). Normal and diabetic rats were fed an oil-free diet containing 2 percent oil ...

In this paper we consider the following property: (⊛ Da) For every function f : R × R −→ R there are functions g 0 n , g 1 n : R −→ R (for n < ω) such that (∀x, y ∈ R)(f (x, y) = n<ω g 0 n (x)g 1 n (y)). We show that, despite some expectation suggested by [Sh 675], (⊛ Da) does not imply MA(σ–centered). Next, we introduce cardinal characteristics of the continuum responsible for the failure of (...
