Optimization of CO2 Biofixation by Chlorella vulgaris Using a Tubular Photobioreactor

Authors: Hossain S.M.Z., Hossain M.M., Razzak S.A.
The effects of various CO2 concentrations in CO2 bioconversion by cultivation of microalga Chlorella vulgaris were investigated using a vertical tubular photobioreactor. The response surface technique with central composite design was applied to model the CO2 biofixation rate, the specific growth rate (SGR), and the biomass productivity of C. vulgaris [...]

A Shariah-compliant portfolio selection model

Authors: Masri H.
The paper aims to develop a Shariah-compliant optimization model for portfolio selection in an Islamic security market. The security return is considered stochastic and is estimated based on the stochastic market return. The proposed model follows Shariah principles by avoiding excessive risk and providing an ethical and socially responsible approach [...]
