abstract human insulin-like growth factor i (higf-i) is a kind of growth factor with clinical significance in medicine. the major objective of this study is over- production of recombinant human insulin-like growth factor i( rhigf-i) through a developed process by recruiting effective factors in order to achieve the most recombinant protein. up to now e. coli expression system has been widely us...

In this work, the effects of operative parameters on CH4, CO2, O2, and N2 membrane gas separation for poly (4-methyl-1-pentane) (PMP) membrane modified by adding nanoparticles of TiO2, ZnO, and Al2O3 are assessed and investigated. The operative parameters were type and percentage of nanoparticles, and cross membrane pr...

The effectiveness of model-based multivariable controllers depends on the quality of the model used. In addition to satisfying standard accuracy requirements for model structure and parameter estimates, a model to be used in a controller must also satisfy control-relevant requirements, such as integral controllability. Design of experiments (DOE), which produce data from which control-relevant ...

Researchers have come a step closer to building one of the world's best dark matter detectors: The U.S. Department of Energy (DOE) recently signed off on the conceptual design of the proposed LUX-ZEPLIN (LZ) experiment and gave the green light for the procurement of some of its components. DOE's SLAC National Accelerator Laboratory, a key member of the LZ collaboration, is setting up a test sta...

A dramatic increase in plastic waste has resulted a strong need to recycling accordingly. selective flotation been highlighted due its outstanding efficiency for the separation of mixed plastics with analogous physicochemical characteristics. In this study, effects design and operational factors on bubble’s hydrodynamic mixing parameters induced air (IAF) device were investigated through experi...

Diabetes poses a serious threat to the health of people around world. Therefore, in 2021, World Health Organisation launched Global Compact, an initiative aimed at improving management and prevention diabetes. The rapid growth number diabetic patients has increased need for insulin. Rapid-acting human insulin analogues, including aspart, improve efficacy therapy. Methods aspart production inclu...
