Saturated hydrocarbons are widely used in the valuation of source rocks and oils, but applicability related parameters has received less attention. Based on thermal simulation experiments Mesozoic Yingen-Ejinaqi Basin, GC-MS analysis saturated hydrocarbon fractions expelled oils extracts from solid residues, to lacustrine oil were discussed. The results indicated that: Controlled by degradation...

Composting is considered to be a primary treatment method for livestock manure and rice straw, and high degree of maturity is a prerequisite for safe land application of the composting products. In this study pilot-scale experiments were carried out to characterize the co-composting process of livestock manure with rice straw, as well as to establish a maturity evaluation index system for the c...

Tilapia production has increased in Aguamilpa Reservoir, in Nayarit, Mexico, in the last few years and represents a good economic activity for rural communities and the country. We determined growth parameters, mortality and reproductive aspects for 2413 specimens of blue tilapia Oreochromis aureus in this reservoir. Samples were taken monthly from July 2000 through June 2001, of which 1 371 we...

The grey mullet fingerling were imported to Iran in 1997 from Hong Kong and in coastal fish pond of north part of Iran were successfully cultured in order to obtain broodstocks and induce artificial reproduction. Seasonal changes in serum concentrations of Testosterone, 17-β Estradiole (E2), 17-α Hydroxy Progesterone and also the level of calcium, Triglyceride and cholesterol in femal...

The objective was to study the behavior of respiration rate (RR) guamara and cocuixtle fruits during storage, effect or maturity stage (green consumption maturity) these on physicochemical parameters specific proteolytic activity, as well antibacterial prepurified proteases fruits. presented a RR 15 mL CO2/kg·h 10 CO2/kg·h, respectively; because ethylene production not detected in any species, ...

We study asymptotics of forward-start option prices and the forward implied volatility smile using the theory of sharp large deviations (and refinements). In Chapter 1 we give some intuition and insight into forward volatility and provide motivation for the study of forward smile asymptotics. We numerically analyse no-arbitrage bounds for the forward smile given calibration to the marginal dist...

the main aim of this research was to estimate the genetic and phenotypic parameters for productive and reproductive traits of esfahan native chickens. traits included body weights at hatch (bw1), 8 weeks of age (bw8), 12 weeks of age (bw12), and at sexual maturity (wsm)], age at sex maturity (asm), egg number (en), average egg weight (aew) in the first 12 weeks of production, and egg production...
