Middle and southern Iraq suffers from polluted soils due to crude oil, spilled on land, leakage from transmitting pipe networks, or petroleum products from refineries. Many researchers have studied pollution impacts on the soil in details, but there is a clear lack of investigation on the influence of crude oil on soil erodibility. Recent researches have investigated the influence of pollution ...

In the “lost notebook”, Ramanujan recorded infinite product expansions for 1 √ r − ( 1−√5 2 )√ r and 1 √ r − ( 1 + √ 5 2 )√ r, where r = r(q) is the Rogers–Ramanujan continued fraction. We shall give analogues of these results that involve Ramanujan’s function k = k(q) = r(q)r(q).

INTRODUCTION The effect of urodynamic catheters on urine flow rate (Q(max) ) is well documented but under-researched. Several studies show reduced Q(max) but methodologies and patient demographics differ. The aims of this study were to further quantify the effect of urodynamic catheters on Q(max) and to explore if this was consistent across different urodynamic diagnoses. METHODS Four groups ...

We have compared the existing experimental data on the leading power corrections to the structure functions F 2 (x, Q 2), F 3 (x, Q 2), and F L (x, Q 2) with the IR-renormalon model predictions for higher-twist contributions. Our analysis shows that the model properly describes the x-dependence, but typically falls short by a factor 2 or 3 as far as the magnitude of higher twist corrections is ...

Deep inelastic electron-proton scattering is analyzed in the target rest frame using a theoretical approach suitable to describe many-body systems of bound constituents subject to interactions. At large three-momentum transfer |q|, this approach predicts the onset of scaling in the variable ỹ = ν-|q|, where ν denotes the energy transfer. The present analysis shows that the data, plotted at cons...
