This paper presents a method for model reference control of a cement-milling circuit that has been studied previously. The approach presented is based on the experimentally justified model developed by Breugesen (1996), and derives the form of control vector with the goal of driving the behavior of the system to that of a desired model. The derivation is based on the Lyapunov theory, and the re...
BACKGROUND & OBJECTIVES Sodium antimony gluconate (SAG) is reported to be losing its efficacy in Bihar as a first line drug for treatment of visceral leishmaniasis (VL). Concerned with the increasing incidence of antimony-resistant VL patients in Bihar, we undertook an epidemiological, clinical and pharmacological study to formulate a scientific basis for choosing a suitable first line drug for...
PURPOSE Oguchi's disease is a rare autosomal recessive disease and known to be caused by mutations in the rhodopsin kinase (GRK1) gene or the arrestin (SAG) gene. SAG contains 16 exons and encodes a protein with 405 amino acids. This study was to identify the underlying genetic defects in a non-consanguineous Chinese family with Oguchi's disease. METHODS Ophthalmologic examinations including ...
BACKGROUND AND OBJECTIVES Cardiovascular outcomes and mortality rates are poor in advanced chronic kidney disease (CKD) patients. Novel risk factors related to clinical outcomes should be identified. METHODS A retrospective analysis of data from a randomized controlled study was performed in 440 CKD patients aged > 18 years, with estimated glomerular filtration rate 15-60 mL/min/1.73m2. Clini...
Although neurons are known to exhibit a broad array of intrinsic properties that impact critically on the computations they perform, very few studies have quantified such biophysical diversity and its functional consequences. Using in vivo and in vitro whole-cell recordings here we show that mitral cells are extremely heterogeneous in their expression of a rebound depolarization (sag) at hyperp...
Voltage sag/swell is one of the most frequently power quality problems which affects the power systems with sensitive loads. The unified power quality conditioner (UPQC) is capable of mitigating the effect of voltage sag/swell at the load or point of common coupling (PCC). In this paper, a new control of UPQC is proposed based on combining the sag detection and voltage injection established on ...
BACKGROUND Previous studies have reached conflicting conclusions regarding the efficacy of mesalazine in the prevention of recurrent diverticulitis. AIM To investigate the efficacy and safety of mesalazine granules in the prevention of recurrence of diverticulitis after acute uncomplicated diverticulitis. METHODS Two phase 3, randomised, placebo-controlled, double-blind multicentre trials (...
cement powder size classification efficiency significantly affects quality of final product and extent of energy consumption in clinker grinding circuits. static and dynamic or high efficiency air separators are being used widely in closed circuit with multi-compartment tube ball mills, high pressure grinding rolls (hpgr) and more recently vertical roller mills (vrm) units in cement plants to c...
(PSERC). PSERC is a multi-university Center conducting research on challenges facing a restructuring electric power industry and educating the next generation of power engineers. of Entergy-New Orleans. In early stages of the project, Mr. Lance Priez of Entergy supplied needed information. The many useful suggestions of all the industrial advisors are acknowledged. Dale Bradshaw of the Tennesse...
