Electrohydraulic expansion joining has great potential for the light weight and high strength thin-walled pipes due to its strain rate. Based on central composite design (CCD) of response surface methodology, multiple experiments electrohydraulic process were performed. The multivariate quadratic nonlinear regression model between parameters (discharge voltage, wire length, diameter) ultimate p...

Investigating the interactions of granular fertilizers with various types equipment is an essential part agricultural research. A numerical technique simulating mechanical behavior assemblies has advantage data trackings, such as trajectories, velocities, and transient forces particles at any stage test. The interaction parameters were calibrated to simulate responses in EDEM, a discrete elemen...

conclusions we found ccd and rsm very effective in optimizing hib culture conditions, and hib biomass production was greatly influenced by ph and incubation temperature. therefore, optimization of the growth factors to maximize hib production can lead to 1) an increase in bacterial biomass and prp productions, 2) lower vaccine prices, 3) vaccination of more susceptible populations, and 4) lower...

background and objective: in the present study, bacillus polymyxa ncim no. 2539 was selected to utilize agro-industrial byproduct (orange peel) for amylase production under submerged fermentation conditions. material and methods: different agro-industrial byproducts like cane molasses, wheat bran, rice bran and orange peel were screened for maximum amylase production. amylase activitiy of bacil...

in the present study lactic acid production was enhanced by optimizing the three process variables viz; inoculum size, temperature and ph using three factor five level ccrd (central composite rotatable design) by lactobacillus delbruckii under smf (submerged fermentation process). paneer (dairy by-product) whey was used as sole substrate for lactic acid production. design expert 8.0.2.0 softwar...

A semiconductor composite photocatalyst, TiO2-ZnO, was synthesized by precipitating ZnO on the surface of commercial TiO2 (aeroxide P25), and used for the photodegradation of diazinon in a 12 W UVC batch photoreactor. Scanning electron microscopy (SEM) investigation revealed a plausible hybridization of TiO2 and ZnO in the composite. Ultraviolet visible (UV-Vis) spectroscopy confirmed a red shi...

Laser-induced breakdown spectroscopy (LIBS) is a fast, low analytical cost, environmentally clean technique that does not require the use of reagents for sample preparation. However, regardless LIBS setup, it has limitations in terms sensitivity and precision, especially when applied to complex samples, such as river sediment. To overcome these limitations, this work, different experimental par...

The recent advances in ocular drug delivery have been successful surpassing conventional therapy, owing to its considerable limitations. This study aims develop and optimize in-situ liposomal system design once-daily liquid preparation treat Keratoconjunctivitis sicca. Liposomes of Hyaluronic acid were prepared using soya lecithin by a thin film hydration method. Eight trial formulations made k...

A simultaneous saccharification and fermentation (SSF) optimization process was carried out on pretreated empty fruit bunches (EFBs) by employing the Response Surface Methodology (RSM). EFBs were treated using sequential acid-alkali pretreatment analyzed physically a scanning electron microscope (SEM). The findings revealed that had changed morphology EFBs’ structure. Then, optimum combination ...

Banana peels waste can be utilized to produce high quality biochar that incorporated into the soil for sustainable production of crops. This research analyzed several properties produced from banana peel at different temperatures, residence times and heating rates. study focuses on yield EDX analysis produced. Response surface methodology using central composite design (CCD) was used optimize t...
