PURPOSE To investigate the effect of feed preparation characteristics and operational parameters on mixing homogeneity in a convective batch ribbon mixer. METHODS Lactose 100M, lactose 200M, ascorbic acid, and zinc oxide powders were used for the mixing study. Operational parameters studied were rotational speed and mixing time. The feed preparations studied were the use of preblending and th...

Abstract Passengers' demands for riding comfort have been getting higher and as the high-speed railway develops. Scientific methods to analyze interior noise of train are needed operational transfer path analysis (OTPA) method provides a theoretical basis guidance control overcomes shortcomings traditional method, which has high test efficiency can be carried out during working state targeted m...

review the literature of conservatism in financial reporting indicates the importance of conservatism in accounting profession. researchers have always tried to determine the degree and ways of conservatism in financial reporting and accounting, although this is not done easily, because there is not a direct measure of conservatism. however, conservatism has been one of the key principles in ac...

In this work, the effects of the types of frother (MIBC, pine oil, and A65) and operational parameters (impeller speed and air flow rate) on the flotation of quartz coarse particles was investigated using nano bubbles (NBs). Quartz particles of the size of -425+106 mm and three types of frother were used for the flotation experiments. Also the impeller speed was 600 to 1300 rpm, and the air flo...

A single beam laser Doppler vibrometer (LDV) has been used in acoustic-to-seismic landmine detection in a stop-andstare scanning mode [Sabatier, J. M. and Xiang, N. IEEE Trans. Geoscience and Remote Sensing 39, 2001, pp.11461154.; Xiang, N. and Sabatier, J. M., J. Acoust. Soc. Am. 113, Mar. 2003]. One of the major requirements is the operational scanning speed in the acoustic detection methods....

The objective of this work was to develop and to evaluate neuro-fuzzy systems as a methodology to describe coffee harvester machine operational performance when compared to multiple regression models. It was considered as input variables fruit maturation index, in the levels of 75.70, 87.00, 98.70%, operational speed, in the levels of 0.16, 0.26, 0.57m.s-1 and rods vibration, in the frequencies...

Isopropyl myristate finds many applications in food, cosmetic and pharmaceutical industries as an emollient, thickening agent, or lubricant. Using a homogeneous reaction phase, non-specific lipase derived from Candida antartica, marketed as Novozym 435, was determined to be most suitable for the enzymatic synthesis of isopropyl myristate. The high molar ratio of alcohol to acid creates novel si...

The main objective of the present work is to analyze the influence of some important operational reaction parameters (agitation speed, polybutadiene – PB – content and initiator concentration) on the final properties of High Impact Polystyrene (HIPS) produced in bulk. Variable effects are analyzed both qualitatively and quantitatively with the help of a fractional factorial design. Physical, ch...

Conceptual models are one of many resources available to pilots for making sense of the flight environment. In this paper we describe the conceptual models a pilot uses, in interviews, to explicate his encounter with a mountain wave while flying an Airbus airplane on the line. In the discourse four models emerge: mountain wave, thrust to control speed, pitch to control speed, and climb-descend ...
