futures contract is one of the most important derivatives that is used in financial markets in all over the world to buy or sell an asset or commodity in the future. pricing of this tool depends on expected price of asset or commodity at the maturity date. according to this, theoretical futures pricing models try to find this expected price in order to use in the futures contract. so in this ar...

using the available information from mazandaran native fowl breeding center as well as studying costs and revenues of poultry, effective factors on profit and the parameters which required to design a model were studied. sensitivity of the model to changes of each parameter in the model tested. the model of this study can be used in similar breeding plans in other provinces after minor changes ...

Air-drying of banana slabs has been investigated and the influence of experimental parameters such as temperature, relative humidity and slab thickness has been studied. This was in part re-investigated because of inconsistencies in previous studies, particularly in relation to derived water diffusion coefficients. In addition, it is shown that harvest season and hence initial moisture content ...

The changing dynamics of organic acids, sugars, phenolics and antioxidant potential in apples from technological to edible maturity was studied. During the time of storage, the content of citric and malic acids generally decreased. The content of sucrose, fructose and glucose decreased significantly in some varieties, while it increased in others. The content of total sugars changed only slight...

The aim of this work was to study the parameters of the composting process of organic wastes originated from mushroom production industry. To accomplish these objectives three piles (P1, P2 and P3) obtained with a spent mushroom substrate (SMS) with different proportions of wheat straw (WS) and urea were composted for 90 days in a static-pile system with continuous monitoring of the process. Sa...

Wind, in the duration of its erosional process, affects considerable changes in a grain's morphologyfrom its removal (detachment) step to sedimentation. In other word, a grain undergoes its gradualevolution during the transit process. In this project, the maturation of Aeolian sand grains had beenstudied upon as based on texture maturity indicator which includes: sorting, mean size grain, round...

BMD does not entirely explain an individual's risk of fracture. The purpose of this study was to assess whether specific differences in spatially resolved bone composition also contribute to fracture risk. These differences were assessed using Fourier transform infrared spectroscopic imaging (FTIRI) and analyzed through multiple logistic regression. Models were constructed to determine whether ...

Traditionally , information security management standards listing generic means of protection have received a lot of attention in the field of information security management. In the background a few information security management-oriente d maturity criteria have been laid down. These criteria can be regarded as the latest promising innovations on the information security checklist standard fa...
