Non-Newtonian flows arise in many processes in
engineering, science and biology for example, in
polymer processing, coating, ink-jet printing,
microfluidics, geological flows in the earth mantle,
homodynamic and many others. Modeling non-Newtonian
flows is important for understanding and predicting
the behaviour of processes and thus for designing
optimal flow configurations. Several models based on
empirical observations have been suggested for these
fluids. A constitutive equation of the non-Newtonian
fluids is in general have their order higher than
those describing the motion of the...

Six genotypes of Tea Camellia sinensis L. i.e., Indonesian, Sri Lankan, Ruopi, Qi men, Chuye & Japanese were tested at NTRI during 2008, for 8 qualitative & 12 quantitative characters. Germplasm was classified into three clusters based on qualitative traits analysis using wards method.This indicates the trait homology between Indonesian & Qi Men for Leaf shape, leaf margin, leaf lower surface, leaf upper surface, shoot color,& posture of leaf base. The linkage distance of their homology is 1.4 LD. The highest value for Veins pairs per leaf showed by Indonesian (13.60), followed by Qi men...

The objective of this study was to investigate the integration of stock market, foreign exchange market and money market in the context of Pakistan. The intra-country integration of these financial markets in the short and long-run are estimated using monthly data covering the period May 1994 to February 2011. To accomplish the objectives we use cointegration analysis and Vector Error Correction Method (VECM). The empirical results from both the techniques of cointegration i.e. the Engle-Granger and Johansen and Juselius (J-J), demonstrate that the Pakistani financial markets are cointegrated...

Urethral stricture is one of the most important causes of bladder outflow obstruction and responsible for significant morbidity. Urethral stricture is more common in men but rare in women. Acquired urethral strictures are mostly due to infection and trauma. Patients who have urethral strictures most often present with obstructing voiding symptoms or urinary tract infections such as prostatitis and epididymitis. Some patients also present with urinary retention.Urethral stricture is a potentially debilitating disease if treated inadequately.
