The available status of Fe, Mn, Cu and Zn in two soils (Melandaha-Silt loam Dhamrai-Silty clay loam) was determined by extraction methods (0.5 M DTPA 0.1 N HCI). previously treated with various composts and/or compost plus fertilizer Amaranthus grown upto 42 days. After harvest Amaranthus, the were extracted 0.5 HCI extracts analyzed for trace elements contents. availability varied significantl...

Solidarity has for a long time been referred to as the core value underpinning European health and welfare systems. But there has been debate in recent years about whether solidarity, with its alleged communitarian content, can be reconciled with the emphasis on individual freedom and personal autonomy. One may wonder whether there is still a place for solidarity, and whether the concept of jus...

A water simulation model (WaSim) to simulate the growth and development of Amaranthus cruentus as well as the components of water balance for a typical sandy-clay-loam soil of Akure has been described. Dry season experiments were carried between January and March of 2005 and 2006. Amaranthus seeds were established on the field and three irrigation water managements were imposed on the crop to d...

Ninety male crossbred pigs were allocated at 30 kg live weight to a 6 5 factorial experiment involving six diets and five levels of feeding where average daily intakes were 1.11, 1.36, 1.67, 1.90 kg and ad libitum between 30 and 60 kg live weight. The control diet contained predominantly animal protein sources, another four diets contained 350 g/kg of either kernels or seeds of either L. angust...

Description: An annual herb reproducing by seed only. Distinguished by flowers and pairs of spiny bracts that occur in the leaf axils. Mature plants are erect, branched and may grow to 1.2 m tall (see Figure 1). Stems are angled in cross section, reddish, fleshy and bear many spines. Leaves are alternate, ovate-rhombic to lanceolate sometimes with sparse hairs on the lower surface and most with...

Acipenseriformes (sturgeon and paddlefish) are basal actinopterygians with a highly derived cranial morphology that is characterized by an anatomical independence of the jaws from the neurocranium. We examined the morphological and kinematic basis of prey capture in the Acipenseriform fish Scaphirhynchus albus, the pallid sturgeon. Feeding pallid sturgeon were filmed in lateral and ventral view...

Furaquinocin is a natural polyketide-isoprenoid hybrid (meroterpenoid) that exhibits antitumor activity and is produced by the Streptomyces sp. strain KO-3988. Bioinformatic analysis of furaquinocin biosynthesis has identified Fur7 as a possible prenyltransferase that attaches a geranyl group to an unidentified polyketide scaffold. Here, we report the identification of a physiological polyketid...

The production of sesquiterpene-type phytoalexins with a vetispyradiene skeleton by Hyoscyamus albus hairy roots induced by methyl jasmonate (MeJA) was reported in a previous paper. The production pattern on co-treatment with cupper sulfate and MeJA (CuSO(4)-MeJA) showed a TLC profile differing from that on treatment with MeJA. Thus, we studied the production of phytoalexins on hairy root cultu...
