This present study was conducted to determine fry production in different male-female sex ratios of Oreochromis niloticusbroodstock order improve production, which handicapped the development fish farming northern Senegal. A total 180 broodfish (47 males and 133 females) were stocked at a density 2 /m2and replicated three times for each ratio 1:2, 1:3and 1:4 (male : female). Mean body weight ra...

This paper evaluates the concept of virtual path (VP) policing as an alternative to virtual channel (VC) policing in an Asynchronous Transfer Mode (ATM) network. The Usage Parameter Control (UPC) function includes a peak rate and a sustainable rate policer. Both policers are implemented based on the Leaky Bucket algorithm defined by the ATM Forum. We implement VC and VP policers in parallel in ...

In this paper nondegenerate multidimensional matrices of boundary format in V0 ⊗ · · · ⊗ Vp are investigated by their link with Steiner vector bundles on product of projective spaces. For any nondegenerate matrix A the stabilizer for the SL(V0)×· · ·×SL(Vp)action, Stab(A), is completely described. In particular we prove that there exists an explicit action of SL(2) on V0 ⊗ · · · ⊗ Vp such that ...

The DNA intercalato!-, 4'-{9-acridinylamino)methanesuIfon-/n-anisidide (m-AMSA) and the nonintercalator, etoposide (VP-16) produce topoisomerase Il-mediated protein-linked DNA strand breaks. This func tion of topoisomerase II was investigated in relation to cell proliferation and cell cycle. Mouse fibroblasts NIH 3T3 and mouse leukemia LI 210 cells stop proliferation when they reach a certain d...

A 2(III)(7-3) fractional factorial experimental design was used to establish 16 culture media, with and without PCBs to enhance the activities of laccase (Lac), manganese peroxidase (MnP), and versatile peroxidase (VP) produced by the white rot fungus Pleurotus ostreatus. The culture was added to 10,000 mg L(-1) of transformer oil, containing 71% of the identified Arochlor 1242. The culture con...

The DNA intercalator, 4'-(9-acridinylamino)methanesulfon-m-anisidide (m-AMSA) and the nonintercalator, etoposide (VP-16) produce topoisomerase II-mediated protein-linked DNA strand breaks. This function of topoisomerase II was investigated in relation to cell proliferation and cell cycle. Mouse fibroblasts NIH 3T3 and mouse leukemia L1210 cells stop proliferation when they reach a certain densi...

In this paper, 3and 4-secure codes are constructed from combinatorial designs. Both constant weight and non-constant weight codes are shown.

Poultry meat is a susceptible product for growth of spoilage and pathogenic microorganisms. The shelf life extension of raw poultry meat is a challenge in food industry. In this research, the combined effect of dipping in a carboxymethyl cellulose (CMC) solution containing black pepper seed (Piper Nigrum) extract (BPE) and turmeric (Curcuma Longa L.) extract (TE) (2% ...

in this research, the effect of active edible coating based on carbocymethyl cellulose (cmc) containing pomegranate peel extract (ppe) and rese essential oil (reo) and also vacuum packaging (vp) on chemical attributes and microbial quality of packaged pomegranate arils during 15 days storage at 5 °c have been studied. the weight loss was increased by increasing storage time. but all treatments ...

3and 4-monoesterified protocatechuic acid methyl ester (5 and 7 respectively) have been synthesised from quinic acid by a high yields biomimetic rearrangement.
