Octenyl succinic anhydride (OSA) modified early Indica rice starch was prepared in aqueous slurry systems using response surface methodology. The paste properties of the OSA starch were also investigated. Results indicated that the suitable parameters for the preparation of OSA starch from early Indica rice starch were as follows: reaction period 4 h, reaction temperature 33.4 °C, pH of reactio...

For any Lie algebra of classical type or type G 2 we define a K-theoretic analog of Dunkl's elements, the so-called truncated Ruijsenaars-Schneider-Macdonald elements, RSM-elements for short, in the corresponding Yang-Baxter group, which form a commuting family of elements in the latter. For the root systems of type A we prove that the subalgebra of the bracket algebra generated by the RSM-elem...

Textbooks on response surface methodology emphasize the importance of lack-of-fit tests when fitting response surface models, and stress that, to be able to test for lack of fit, designed experiments should have replication and allow for pure-error estimation. In this paper, we show how to obtain pure-error estimates and how to carry out a lack-of-fit test when the experiment is not completely ...

A fundamental goal of evolutionary ecology is to understand how asymmetric competition influences phenotype expression, yet few studies have quantified the relative effects of intraand interspecific competition on phenotypes. We examined the effects of intraand interspecific larval competition on both discrete and continuous phenotype expression of the facultatively paedomorphic mole salamander...

Articular cartilage is a low-friction white connective tissue. The only cell type in articular are chondrocytes. They permit smooth articulation cartilage. have insufficient regenerative capacity. Response surface methodology very useful tool for the modelling of any processes using polynomials. This study investigated depth-dependent chondrocyte area from bovine Confocal microscope was utilize...

abstract: the combination of pulsed vacuum osmotic dehydration and microwave drying of garlic bulbs were examined. the response surface methodology (rsm) was used to determine the effect of nacl concentration (8%-20%), osmotic solution temperature (25-65°c), operation pressure (240-830 mbar), immersion time (20-300 min) and microwave power level (100-600 w) on water loss (wl), solids gain (sg),...

: Unwanted water production from oil and gas reservoirs is a serious problem for producers. Preformed particle gel (PPG) treatment is a benefit approach to control excess water production. Swelling percentage of PPG samples in saline water is a key factor affecting the efficiency of the water conformance process. In this study, an efficient series of PPGs were synthesized and their swelling beh...
