Abstract The cable industry is beginning to migrate to 100G core optical transport waves, which greatly improve fiber utilization while lowering transponder count for equivalent transport bandwidth. However, transporting 100G waves requires complex optical modulation to preserve performance and increase spectral efficiency. These modulation methods require several additional discrete optical co...

Atlantic mackerel (Scomber scombrus) and horse (Trachurus trachurus), locally known as kote, are fishery species consumed in Nigeria due to their high nutritional values. This research determined the composition of local dried fish, Scomber scombrus Trachurus trachurus. Results for shows mean value moisture, ash, crude fat, fiber, protein contents percent (%) as: 5.260.00, 5.200.10, 35.600.00, ...

The study was undertaken to evaluate some chemical parameters of powder milk available in Mymensingh town. Powder milk samples of six different brands namely Kwality, NIDO, Diploma, Anchor, Farmland & Starship were collected from local market. Powder samples were analyzed to know the chemical (P, acidity, fat, protein, lactose, ash, moisture, solids-not-fat, total solids) characteristics. P, ac...

this research carried out in the rafsanjan pistachio orchard to investigate the effect of n form, manure, k and fe on yield, nut quality and leaf mineral nutrients concentrations of pistacia vera l. cv. fandoghi grafted on badami-riz zarand rootstock. the experiment was as factorial with four factors including; manure (without manure and 10 kg tree-1 sheep manure), n form (ammonium sulfate and ...

We investigate the Zagreb index, one of the topological indices, of random recursive trees in this paper. Through a recurrence equation, the first two moments of Zn, the Zagreb index of a random recursive tree of size n, are obtained. We also show that the random process {Zn − E[Zn], n ≥ 1} is a martingale. Then the asymptotic normality of the Zagreb index of a random recursive tree is given by...

sunflower (helianthus annus l.) is the most important between oil plants in iran. the objective of this study was to evaluate the effects of micronutrients application on the sunflower yield under drought stress. this experiment was carried out at golmakan agriculture research station (iran) in 2005 that using a split plot randomized complete block design with four replications. irrigation was ...

Experiment on evaluation of mango genotypes under high density planting system was conducted in six varieties the same age group (5 years). The observation tree characters indicated that trunk circumference ranged from 20.51 cm (Prior) to 31.29 (Chandrakaran) and crown diameter 2.39 m (Ratna) 3.09 (Vellaikolumban). qualitative data morphological viz., tree, leaf, inflorescence, fruit, stone see...

A nanocrystalline TiO(2) film with highly dispersed Zn-doping shows its capability for efficient electron transport in dye-sensitized solar cells (DSSCs). The Zn-doping is conducted via Zn(2+) introduction into a layered titanate followed by hydrothermal treatment and calcination. The Zn-doped films exhibit an elevated electron Fermi level, which may enhance band bending to lower the density of...
