Two mine tailings are evaluated for their potential as supplementary cementitious materials. The were milled using two different methods – ball milling 30 minutes and disc durations ranging from 1 to 15 minutes. modified R3 test was carried out on the quantify reactivity. reactivity of is greater than those tailings. Strong correlations obtained between duration, median particle size, amorphous...

reactivity (AHR), because of inherent problems with using a pharmacologic agent in epidemiologic surveys. To our knowledge, no studies exist that compare MIC with EVH in known asthmatics. We conducted a prospective, randomized, crossover trial with a group of subjects (n = 16) who met the American Thoracic Society definition of asthma with these objectives: (1) to compare the sensitivity of EVH...

We study the conditions for reactivity enhancement of catalytic processes in porous solids by use of molecular traffic control (MTC) as a function of grain size. We extend a recently introduced two dimensional model system to three dimensions. With dynamic Monte-Carlo simulations and analytical solution of the associated Master equation we obtain a quantitative description of the MTC effect in ...

The Homogeneous Charge Compression Ignition is an alternative combustion technology that can reduce automobile pollution, provided that the exhaust emission can be controlled. A parametric study can be useful in order to gain more understanding in the emission reduction possibilities via this new combustion technology. For this purpose, the inlet temperature, the equivalence ratio and the compr...

Systematic parameter survey calculations were performed to investigate basic characteristics (burnup reactivity loss, Doppler coefficient, sodium void reactivity , control rod worth , power distribution, transmutation rate, breeding ratio etc.) of an LMFBR core loaded with minor actinide (MA) fuels which contain rare earths (RE) and a}so to establish MA and RE loading method which has no seriou...

Assays monitoring P2Y12 platelet reactivity can accurately predict which patients will have a poor response to clopidogrel. We sought to determine the cost-effectiveness of using platelet reactivity assays (PRAs) to select a dual-antiplatelet regimen for patients with acute coronary syndrome. A hybrid decision tree Markov model was developed to determine the cost-effectiveness of universal clop...

allergic rhinitis is an extremely common disease worldwide. aeroallergens are very often involved in allergic rhinitis and their prevalence may vary in differ¬ent regions. the causative allergens of allergic rhinitis in our area are unknown. the purpose of this study was to determine the prevalence of skin reactivity to different aeroallergens in patients with allergic rhinitis in the city of s...

Limb-shaking is a specific clinical feature of transient ischaemic attacks that has been associated with a high-grade stenosis or occlusion of the internal carotid artery. The aim of this study was to describe the clinical characteristics of limb-shaking in patients with internal carotid artery occlusion and to investigate whether patients with limb-shaking have a worse haemodynamic state of th...
