The extraction of catfish (Clarias gariepinus) bone gelatin was optimized by using Response Surface Methodology (RSM) involving 4-factors, 5-levels Central Composite Design (CCD). The optimum conditions for extraction were produced by a pre-treatment of 3.35% HCl for 14.5 h along with hot water extraction at 67.23°C for 5.2 h. Results showed that the predicted yield by RSM (61.81%) was closely ...

Let RsM denote the Singer construction on an unstable module M over the Steenrod algebra A at the prime two; RsM is canonically a subobject of Ps⊗M , where Ps = F2[x1, . . . , xs] with generators of degree one. Passage to A -indecomposables gives the natural transformation RsM → F2⊗A (Ps⊗M), which identifies with the dual of the composition of the Singer transfer and the Lannes-Zarati homomorph...

Abstract: Robust design (RD), implemented in statistical and mathematical procedures to simultaneously minimise the process bias and variability, is widely used in many areas of engineering and technology to represent complex real-world industrial settings. For RD modelling and optimisation, response surface methodology (RSM) is often utilised as an estimation method to represent the functional...

Recurrent spontaneous miscarriage (RSM), defined as ≥2 clinically detectable pregnancy losses before 20 weeks of gestation with the same partner. Many studies have been suggested abnormal natural killer (NK) cell activity can be a high chance division linked with RSM. Aberrant expression of angiogenic cytokines during implantation window in women with RSA is one of the key factors that adversel...

Semantics shows diversity in real world, document world, mental abstraction world and machine world. Transformation between semantics pursues the uniformity in the diversity. The Resource Space Model (RSM) is a semantic data model for organizing resources based on the classification semantics that human often use in understanding the real world. The design of a resource space relies on knowledg...
