Abstract Intensifying hydrogen use in the blast furnace is a key technology for significant coke and CO 2 emissions reductions. The most straightforward approach implementation of high hydrogenous gas injection rates BF tuyeres. Yet this solution has not been widely implemented due to lack understanding impact on furnace’s internal state. In paper, newly developed mathematical model presented v...

Chronic allograft vasculopathy (CAV) is an atheromatous-like lesion that affects vessels of transplanted organs. It is a component of chronic rejection that conventional immuno-suppression fails to prevent, and is a major cause of graft loss. Indirect allo-recognition through T cells and allo-Abs are critical during CAV pathogenesis. We tested whether the indirect allo-response and its impact o...

These lectures, presented at the 2021 Les Houches Summer School on Dark Matter, provide an introduction to key methods and tools of indirect dark matter searches, as well a status report field circa summer 2021. Topics covered include possible effects energy injection from early universe, calculate both expected distribution spatial particles produced by interactions, outline theoretical models...

BACKGROUND Cytomegalovirus retinitis is a neglected disease in resource-poor settings, in part because of the perceived complexity of care and because ophthalmologists are rarely accessible. In this paper, we describe a pilot programme of CMV retinitis management by non-ophthalmologists. The programme consists of systematic screening of all high-risk patients (CD4 <100 cells/mm3) by AIDS clinic...

the study of interactions of jet into cross flow at different longitudinal and transverse angles ofjet was studied. the following components were designed and constructed: a low velocity windtunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jetinjection, and a spatial rake to measure the total pressure. the tests were carried out atlongitudinal (α...

The pilot-scale NOx and SOx simultaneous removal from boiler emission was performed using radical injection and chemical hybrid process. The radical injection is often called as indirect plasma (or remote plasma) and air radicals are produced at room temperature with less than 1/10 of the flue gas flow rate. The flue gas from the boiler was in the range of 450~1,470 Nm/hr, the gas temperature o...

A component in extracts of Group A streptococci suppresses antibody formation in mice against heterologous erythrocyte and protein antigens. Large doses are not toxic and repeated injection does not change its effectiveness. It is most effective when injected 1 or 2 days before antigen and it is not suppressive when given after antigen. The active factor occurs as a large polydisperse complex a...

Hydrolyzed gallic acid in Potentilla chinensis Ser. was determined by HPLC using Potentilla chinensis Ser. as a model drug with chromatographic conditions as follows: Hypersil C18 column (250 mm × 4.6 mm, 5 μm); mobile phase methanol-0.05% aqueous solution of phosphoric acid (10:90); volume flow 1.0 mL/min; detection wavelength 271 nm; column temperature 25°C; and injection volume 20 μL. Inject...

Maximization of the catalyst efficiency in automotive fuel-injection engines requires the design of accurate control systems to keep the air-to-fuel ratio at the optimal stoichiometric value AF . Unfortunately, this task is complex since the air-to-fuel ratio is very sensitive to small perturbations of the engine parameters. Some mechanisms ruling the engine and the combustion process are in fa...
