In the current paper, specimen notch geometries during plane strain tensile test for cold-rolled steel DC01 is studied and optimized using Response Surface Methodology (RSM) desirability approach. The angle (X°), width (d), length (c) were main geometry parameters considered in this study. effects of these on state expressed by self-defined metrics, namely Plane Strain State Index (PSSI) Homoge...

The development of banana-based snack bars that fulfill the nutritional requirement for toddlers is required. In this study, we analyzed effects different concentrations banana puree, flour and potato starch on characteristics inulin, dietary fiber, protein, potassium as well hardness using response surface methodology. total, 14 experimental models were generated a simplex lattice design. Resu...

In this study, it was aimed to predict and optimize the effects of acetone/gasoline mixtures on spark ignition engine responses at different speeds advance values with artificial neural network response surface methodology. The regression results obtained from methodology show that absolute variance ratio for all answers are greater than 0.96. Correlation coefficient were higher 0.91. Mean perc...

Domperidone Maleate (DOM), an antiemetic drug, has been used in treatment of adults and children. It has low aqueous solubility and hence low bioavailability. In present study, an attempt has been made to enhance the solubility of DOM by inclusion complexation with Hydroxypropyl-βCyclodextrin (HP-β-CD) using kneading technique and formulation of fast disintegrating tablets by using Sodium Starc...

Abstract Threadfin bream ( Nemipterus sp .) is a demersal fish that widely distributed in Indonesian waters. Protein content of 16.85% and fat 2.2%. High protein low-fat make potential as raw material for hydrolysate. The purpose this study was to determine the effect differences papain enzyme concentration, temperature, duration hydrolysis process on degree optimal time using Response Surface ...

BACKGROUND Bacteria play critical roles in marine nutrient cycles by incorporating and redistributing dissolved organic matter (DOM) and inorganic nutrients in the ocean. TonB-dependent transporter (TBDT) proteins allow Gram-negative bacteria to take up scarce resources from nutrient-limiting environments as well as siderophores, heme, vitamin B12, and recently identified carbohydrates. Thus, t...

Naturally occurring dissolved organic matter (DOM) and biosolids-derived DOM have been implicated in the mobility of metals in soils and aquifer materials. To investigate the effect of DOM on copper mobility in aquifer material, DOM derived from sewage biosolids was separated into two apparent molecular-weight (MW) fractions, 500 to 3500 Da (LMW) and > 14 000 Da (HMW). In each MW fraction, the ...
