of ann-dimensional manifold without boundary into Euclidean space. We say Af = x(Mn) moves by mean curvature if there exists a one-parameter family Xt = x( ·, t) of immersions with corresponding images J..!I1 = x 1(lvfn) satisfying d dtx(p,t) = -H(p,t)v(p,t) (1) x(p,O) = xo(P) for some initial data xo. Here H(p,t) and v(p,t) denote mean curvature and outer unit normal of the hypersurface M 1 at...

BACKGROUND The number of (trinucleotide) CAG repeats within the androgen receptor (AR) gene is inversely correlated with transcriptional activity of testosterone-target genes. Although abnormally long CAG repeats are strongly associated with male infertility, it is unclear whether CAG repeat length polymorphism can affect androgen receptor activity and sperm parameters. To explore the previousl...

BACKGROUND being unmarried is associated with worse health and increased mortality risk. Telomere length has emerged as a marker for biological ageing but it is unclear how telomere length relates to marital status. OBJECTIVE to examine the relationship between telomere length and marital status in a sample of middle-aged adults. DESIGN AND SUBJECTS cross-sectional analysis among 321 adults...

OBJECTIVE To compare the postoperative outcome of stapled haemorrhoidectomy and conventional Milligan Morgan's open haemorrhoidectomy. STUDY DESIGN Comparative study. PLACE AND DURATION OF STUDY Surgical Unit 1, Ward-3, Department of Surgery, Jinnah Postgraduate Medical Centre, Karachi, from March to September 2006. METHODOLOGY Sixty patients of late 2nd, 3rd and 4th degree haemorrhoids w...

CD = dimensionless mean drag coefficient, 2F D= fU meanD F D = drag force per unit spanwise length on the cylinder and plate, Nm 1 D = diameter of the cylinder, m E = dimensionless Young’s modulus, E = fU mean f = dimensionless oscillation frequency of the plate, f D=Umean Re = Reynolds number, fUmeanD= Umean = mean velocity at the left boundary of the channel, ms 1 V = dimensionless dilatation...

in R, where t ranges over the unit circle S = R/2πZ. The curve Uk(t) is locally neighborly: as long as t1, . . . , tk lie in an open arc of S of a certain length φk > 0, the convex hull of the points Uk (t1) , . . . , Uk (tk) is a face of Bk. We characterize the maximum possible length φk, proving, in particular, that φk > π/2 for all k and that the limit of φk is π/2 as k grows. This allows us...

background orientation of the stylohyoid complex (shc) may be important for evaluation of the patient with orofacial pain or dysphagia. objectives our purpose was to assess the length and angulations of shc using cone beam computed tomography (cbct). patients and methods in this study, 3d images provided by cbct of 69 patients (36 females, 33 males, age range 15-77 years) were retrospectively e...

We study syndetic sensitivity and mean for linear dynamical systems. For the aspect, we obtain some properties of adjoint operators left multiplication operators. also show that there exists a system (X×Y,T×S) such is cofinitely sensitive but (X,T) (Y,S) are not syndetically sensitive. if sensitive, where Y complex Banach space, spectrum T meets unit circle. results regarding perturbations.
