We perform absolute timing of PSR B1821−24 in M28, using a 50 ksec observation with Chandra/HRC-S. We have obtained the highest signal-to-noise X-ray pulsed lightcurve of this source to date, detecting two X-ray pulses, as well as significant non-pulsed emission – a persistent X-ray flux which comprises 15±3% of the total X-ray flux of the pulsar. The Gaussian width of the sharp X-ray peak is 3...
Engine performance depends on two main factors of engine speed and ignition time. Ignition timing can affect engine life, fuel economy and engine power. In this paper, to study engine performance of Peugeot 206 TU3A with comparison ratio of 10.5:1 and displacement of 1361CC in MATLAB software, a two-zone burned/unburned model with the fuel burning rate described by aWiebe function was used for ...
In conversations between native speakers, words such as ‘same’ and ‘identical’ do not usually cause much difficulty. We take it for granted that others use them with the same sense as we do. If it is unclear whether numerical or qualitative identity is intended, a brief gloss such as ‘one thing not two’ for the former or ‘exactly alike’ for the latter removes the unclarity. In this paper, numer...
Importance Timing of introduction of allergenic foods to the infant diet may influence the risk of allergic or autoimmune disease, but the evidence for this has not been comprehensively synthesized. Objective To systematically review and meta-analyze evidence that timing of allergenic food introduction during infancy influences risk of allergic or autoimmune disease. Data Sources MEDLINE, E...

PURPOSE To examine the effect of recall timing on training-session rating of perceived exertion (sRPE) in a population of athletes well familiarized with the method and procedures during a 5-d training microcycle. METHODS Fifty-one top-class field referees (FRs) (age 38.4 ± 3.3 y, height 181 ± 5.6 cm, body mass 76.8 ± 6.8 kg, body-mass index 23.4 ± 1.7 kg/m2, body fat 20.4% ± 3.6%, internatio...
