The very bright electron beam required for an x-ray free-electron laser (FEL), such as the linac coherent light source (LCLS), is susceptible to a microbunching instability in the magnetic bunch compressors, prior to the FEL undulator. The uncorrelated electron energy spread in the LCLS can be increased by an order of magnitude to provide strong Landau damping against the instability without de...
An economic evaluation of newly developed methods for disinfesting empty grain storage bins by heat treatment will be a useful tool for decision-making by grain storage managers. An economic empirical model of heat treatment and chemical applications was developed using minimization of costs at a target risk level associated with the grain-damaging insects Tribolium castaneum (Herbst), Sitophil...
An alternative to fumigants and insecticides for controlling stored-product insects in empty grain storage bins prior to filling is heat treatment, in which the temperature is quickly raised to a minimum of 50 1C and held there for 2–4 h. Effectiveness of heat treatment on empty grain storage bins was evaluated for five commercial propane and electric heat-treatment systems by measuring air tem...
In situ hybridization (ISH) is a method that uses labeled complementary single strand DNA or RNA to localize specific DNA or RNA sequences in an intact cell or in a fixed tissue section. The main steps of ISH consist of: probe selection, tissue or sample preparation, pre-hybridization treatment, hybridization and washing, detection and control procedure. Probe selection is one of the important ...
This paper reports the development of a computer approach for evaluating the general performance of stand-alone wind/photovoltaic generating systems. Simple models for different system components are developed, integrated, and used to predict the behavior of generating systems based on available wind/solar and load data. The model is useful for evaluating the performance of stand-alone generati...
In this paper double flow packed bed solar air heater has been investigated theoretically. The effect of air mass flow rate, porosity and different depth ratios at study state conditions on the thermal performance of a double flow packed bed solar air heater is found by using the alternative simulation system. Comparisons between the measured thermal and effective thermal efficiency of the doub...
Nosocomial infections acquired during the course of cardiac surgery and hospitalization can have devastating patient consequences. The source of these infections is often difficult to determine which complicates eradication efforts. Recently it has become apparent that the heater-cooler devices used in conjunction with cardiopulmonary bypass may become contaminated with bacteria that are normal...
Natural convection in an annulus with a discrete heat source on the inner cylinder is studied numerically. The outer cylinder is isothermally cooled at a fixed low temperature, and the top wall, the bottom wall and unheated portions of the inner cylinder are thermally insulated. For low applied heat flux through the heater, as measured non-dimensionally by a Grashof number, Gr , the flow in the...
included gastric antral vascular ectasia (GAVE) (6), GAVE and AD (6), tumor (9), polyps (2), Crohn’s disease (3), NSAID ulceration (3), peptic ulcer disease (3), varices (2), small bowel ulcers (4), Dieulafoy (1), and miscellaneous (11). Carey described advanced age as the only predictive factor in overt OGB. However, in our data set (using multivariate analysis), both transfusion dependence (P...
Breast cancer remains the leading cause of cancer and the third leading cause of cancer related deaths among our population with an estimated number of 246,660 new cases and 40,450 deaths in 2016. With treatment advancements, including targeted agents such as Everolimus, a mammalian target of rapamycin (mTOR) inhibitor, survivability and quality of life continue to improve. However, with the us...
