Ebook "Ultrasonic coal-wash for de-ashing and de-sulfurization: Experimental investigation and mechanistic modeling" focuses on the physical aspects of ultrasonic de-ashing and de-sulfurization, such as cavitation, streaming and their combined effects. Ambedkar Balraj proposes an ultrasound-assisted coal particle breakage mechanism and explores aqueous and solvent-based ultrasonic techniques for de-ashing and de-sulfurization. Ambedkar designs a Taguchi L-27 fractional-factorial matrix to assess the individual effects of key process variables.

In this study, extreme halophilic archean Natrialba asiatica was utilized as a new source for lipase production. Lipases from halophilic archaea are appealing for utilization in assorted industrial and biotechnological applications. The optimum temperature and pH of N. asiatica lipase in the crude mixture were 50 °C and 10, respectively. The growth conditions influencing lipase production were determined using a two-level fractional factorial Plackett–Burman design. Among the 9 factors screened, MgCl2 concentration, temperature, and shaking were found to be effective.

In this paper, in order to construct a 3D quantitative structure–activity relationship (QSAR) model with the chlorobenzene (CB) molecular structure parameter as an independent variable and the octanol-water partition coefficient (KOW ) as a dependent variable, 9 kinds of CB molecules were used as training sets and 3 kinds of CB molecules were used as test sets. We adopted the QSAR module in the Sybyl-X2.0 software from the Tripos Corporation (USA).

Successful pellet production has been reported in literature with cross-linked poly(vinylpyrrolidone), Polyplasdone® XL-10 and INF-10. In the present study, a quality by experimental design approach was used to assess several formulation and process parameter effects on the characteristics of Polyplasdone® XL-10 pellets, including pellet size, shape, yield, usable yield, friability, and number of fines. The hypothesis is that design of experiments and appropriate data analysis allow optimization of the Polyplasdone product.

Field experiments were conducted with hybrid brinjal under IPNS during 2017-18 adopting Inductive cum Targeted yield model (Ramamoorthy et al, 1967) to develop postharvest soil test values (PHSTVs) prediction equations on Visakhapatnam soil series (TypicHaplustept) which is rednon-calcareous.

Surfactant-enhanced hollow fiber liquid phase (SE-HF-LPME) microextraction was applied for the extraction of melamine in conjunction with high performance liquid chromatography with UV detection (HPLC–UV). Sodium dodecyl sulfate (SDS) was added firstly to the sample solution at pH 1.9 to form hydrophobic ion-pair with protonated melamine. Then the protonated melamine–dodecyl sulfate ion-pair (Mel–DS) was extracted from aqueous phase into organic phase immobilized in the pores and lumen of the hollow fiber.

The aim of this investigation was to optimize immobilization conditions to entrap Kluyveromyces marxianus DBKKUY-103 during ethanol fermentation from sweet sorghum juice using a response surface methodology. The effects and interactions of variables involved in cell entrapment using polyvinyl alcohol and sodium alginate were studied through a fractional factorial design.

(BQ) This study was made only for the finish stages and has been carried out on the influence of five design factors: intensity supplied by the generator of the EDM machine (I), pulse time (ti), duty cycle (η), open-circuit voltage (U) and dielectric flushing pressure (P), over the two previously mentioned response variables. This has been done by means of the technique of design of experiments (DOE), which allows us to carry out the above-mentioned analysis performing a relatively small number of experiments.

Nearly a decade has passed since the publication of the first edition. Many instructors have used the first edition to teach master's and Ph.D. students. Based on their feedback and our own teaching experience, it became clear that we needed to revise the book to make it more accessible to a larger audience, including upper-level undergraduates. To this end, we have expanded and reorganized the early chapters in the second edition. For example, our book now provides a self-contained presentation of regression analysis (Sections 1.4-1.

An ideal way to run this experiment would be to run all the 4x3=12 wafers in the same furnace run. That would eliminate the nuisance furnace factor completely. However, regular production wafers have furnace priority, and only a few experimental wafers are allowed into any furnace run at the same time. Non-Blocked method A non-blocked way to run this experiment would be to run each of the twelve experimental wafers, in random order, one per furnace run.
