Designing a glycemic control strategy to maintain glucose homeostasis and prevent hypoglycemia for subjects with type 1 diabetes

A. Rafie Lak; O. Vahidi

Volume 15, Issue 3 , September 2018, Pages 34-52

  This paper presents using the fractional PImDn controller module which manipulates insulin infusion rate to maintain normoglycemia in subjects with type 1 diabetes. To prevent severe hypoglycemia, a conventional proportional controller is used to regulate glucagon infusion rate when the blood glucose ...  Read More

CFD simulation for segregation behavior of a ternary mixture in a bubbling fluidized bed: effect of solid wall boundary condition

M. rasteh; F. Farhadi

Volume 15, Issue 3 , September 2018, Pages 53-71

  Abstract The effect of the solid–wall boundary condition on the segregation behavior of a sand ternary mixture differing in size but having the same proportion has been investigated in a gas–solid bubbling fluidized bed. A multi-fluid computational fluid dynamics model incorporating the kinetic ...  Read More

An experimental investigation on the effect of acid treatment of MWCNTs on the viscosity of water based nanofluids and statistical analysis of viscosity in prepared nanofluids

S. Abbasi

Volume 15, Issue 3 , September 2018, Pages 72-81

  The effect of temperature (25, 40, 55 and 70°C) and weight fraction of MWCNTs (0.125, 0.25 and 0.5 %wt) on the viscosity of nanofluids containing pristine and functionalized MWCNTs have been investigated. For this purpose, all of the measurements were carried out in triplicate and were analyzed using ...  Read More

Application of artificial neural network in deoxygenation of water by glucoseoxidase immobilized in calcium alginate/MnO2 composite

A. Abdi; M.Sh Izadkhah; A. Karimi; M. Razzaghi; H. Moradkhani

Volume 15, Issue 3 , September 2018, Pages 82-93

  A three-layer artificial neural network (ANN) model was developed to predict the remained DO (deoxygenation) in water after DO removal with an enzymatic granular biocatalyst (GB), based on the experimental data obtained in a laboratory stirring batch study. The effects of operational parameters such ...  Read More

Catalytic reduction of SO2 with CH4 to elemental sulfur: A comparative analysis of alumina, copper-alumina and nickel-alumina catalysts

S.E Mousavi; H. Pahlavanzadeh; M. khani; H. Ale ebrahim; A. Mozaffari

Volume 15, Issue 3 , September 2018, Pages 94-107

  The catalytic reduction of sulfur dioxide with methane to form elemental sulfur has been studied. Al2O3, Cu-Al2O3 and Ni-Al2O3 were examined as catalysts and their performances were compared in terms of SO2 conversion and selectivity. Performance of the catalyst extremely enhanced when nickel and copper ...  Read More
