central composite design (ccd; 5 levels and 3 factors) and response surface regression (rsreg) were used to evaluate the response of broiler chicks [average daily gain (adg), feed conversion ratio (fcr) and feed intake (fi)] to dietary requirements of  lysine (lys), methionine (met) and threonine (thr). a total of 60 battery brooder units of 6 birds each were assigned to 15 diets in 3 replicati...

The purpose of this paper is to present an integrated approach for improving the quality characteristics of the injection molded part (Honda Upper Part) being manufactured at manufacturing industry (Pakistan), where the rejection rate for Honda upper part was on ramp due to sink marks defects. The proposed integrated approach embraces the concept of Design of Experiments (Taguchi Approach) and ...

biodegradation of phenanthrene (phe) was studied in aqueous culture to demonstrate the potential of the mixed culture in degrading high concentration of phe. the experiments were conducted to monitor biodegradation of phenanthrene for duration of 6 days. biodegradation of phe was successfully achieved in low and middle concentration by the isolated mixed culture. a full factorial central compos...

in this study, the adsorption of 1-chloro-4-nitrobenzene (1c4nb) on carbon nanofibers (cnfs), was investigated in a batch system. the combined effects of operating parameters such as contact time, ph, initial 1c4nb concentration, and cnfs dosage on the adsorption of 1c4nb bycnfs were analyzed using response surface methodology (rsm). the analysis of variance results confirmed that there was sig...

response surface methodology (rsm) was employed to determine the optimum processing conditions leading to maximum anthocyanin, phenolic compound and antioxidant activity during osmo-ultrasonic pretreatment followed by hot air drying of black cherry fruit. temperature (40, 50 and 60ºc), sucrose content (40, 50 and 60% w/v) and ultrasound frequency (0, 65 and 130 khz) were the factors investigate...

The surface roughness value (Ra) of sintered iron P/M components at different cutting speed has been investigated. Surface finish may also be critical for component assembly or system performance. Dimensional fit and mating surface interaction may require certain surface finish requirements to meet performance specifications. Experimental results of surface roughness (Ra) of P/M components at d...

In this study, the adsorption of 1-chloro-4-nitrobenzene (1C4NB) on carbon nanofibers (CNFs), was investigated in a batch system. The combined effects of operating parameters such as contact time, pH, initial 1C4NB concentration, and CNFs dosage on the adsorption of 1C4NB byCNFs were analyzed using response surface methodology (RSM). The analysis of variance results confirmed that there was sig...

The present research work aims to demonstrate the effectiveness of the new methodology of Design of Dynamic Experiments (DoDE) in optimizing an important pharmaceutical reaction. An easily developed response surface model (RSM) is used instead of a hard to develop knowledge-driven process model. The DoDE approach allows the experimenter to introduce dynamic factors in the design, which during t...
