Long distance contribution toD→πl+l−

Long Distance Contribution to KL → ℓ + ℓ −

We revisit the calculation of the long distance contribution to K L → µ + µ −. We discuss this process within the framework of chiral perturbation theory, and also using simple models for the K L γ * γ * ver-tex. We argue that it is unlikely that this mode can be used to extract information on short distance parameters.

The Long Distance Contribution to D → πl + l −

We calculate the long distance contribution to D +,0 → π +,0 l + l − decays by the use of a vector meson dominance model, in which the φ-meson plays the central role. The branching ratios obtained are 10 −6 and a few times 10 −7 for the resonance and non-resonance regions respectively. The analysis includes a calculation of D + → π + φ, consistent with the experimental value.

Contribution of Iliopsoas and Quadratus Lumborum Muscle Size on Long Distance Runners

A hypertrophy of psoas muscle (PM) is assigned to be one of the major determinants for sprint running [2]. Moreover, the erector spinae and quadratus lumborum muscles related to the sprint performance [3]. These results suggest that higher sprint performance require the stabilization of the trunk lateral movement. The main function of PM is to flex the thigh on the pelvis, but also counteract a...

Distance Is Dead , Long Live Distance

For many educators, the phrase ‘from distance education to e-learning’ conjures up the view of an ‘evolutionary’ progression beginning with correspondence study and developed through more sophisticated technologies to its current identification with computers, the Internet, and the World Wide Web. For others, particularly those with little knowledge or experience of (and often equally little in...
