Effects of grain species and grain processing method on DMI, rate and efficiency of gain, and feeding value for cattle fed high concentrate diets were appraised by statistically compiling results from 605 comparisons from feeding trials published in North American journals and experiment station bulletins since 1974. Metabolizable energy (ME) values for each grain and processing method were cal...

Relational transducers mapping sequences of input relations to sequences of output relations are proposed for high-level declarative specifications of business models. See [404] for a related class of ASM-transducers. Contains the problem description for the steam boiler control competition [7] and 22 proposed solutions obtained using the major known formal methods, with text and complete docum...

The ElectroCore is a new particulate control technology which is intended to augment the performance of aging or underperforming ESPs. Unlike conventional electrostatic precipitators which collect particles on their surfaces, the ElectroCore acts as a separator thereby allowing it to overcome many of the common reentrainment problems. A pilot-scale Advanced ElectroCore Field Prototype was insta...

The Biqian-10 block, located in Henan Oilfield of Sinopic, contains many thin and interbedded reservoirs, which have been operated by cyclic steam stimulation for 20 years or more. Therefore, it is a challenge to implement the conventional steam flooding. In order to improve the recovery of steam flooding, urea was used to assist steam flooding. Urea can decompose into CO2 and NH3, which are be...

the composition of the essential oils of teucrium chamaedrys l. belongs to the family lamiaceae, it is growing wild in the margin of mountainous roads of arid and cold climate of north iran. in this research, essential oils of t. chamaedrys, extracted and measured at the different location by different methods of distillationand then were analyzed by gc and gc/ms. investigation and comparison o...

Part 1 is the first part in a series dealing with utilization of municipal solid waste �s an auxiliary fuel for utility class steam generators. It considers the resource characteristics of refuse as a fuel and the eco­ nomics of such use in comparison with conventional disposal techniques. The primary objective was to establish the impact such refuse use would have, if extensively practiced in ...

We analyse the one-dimensional motion of a uniform thin fibre which is pulled upwards from a horizontal plane by a constant vertical force exerted against the homogeneous gravitational field. The solution of the equation of motion which describes this variable mass problem is discussed and the character of the resulting damped oscillations is described. 1. Historical background and formulation ...

Volatile components from Exocarpium Citri Grandis (ECG) were, respectively, extracted by three methods, that is, steam distillation (SD), headspace solid-phase microextraction (HS-SPME), and solvent extraction (SE). A total of 81 compounds were identified by gas chromatography-mass spectrometry including 77 (SD), 56 (HS-SPME), and 48 (SE) compounds, respectively. Despite of the extraction metho...

BACKGROUND/AIM Polymethyl methacrylate is used for producing a denture basis. It is a material made by the polymerization process of methyl methacrylate. Despite of the polymerization type, there is a certain amount of free methyl methacrylate (residual monomer) incorporated in the denture, which can cause irritation of the oral mucosa. The aim of this study was to determine the amount of resid...
