A program code to simulate neutron interactions with a CR-39 detector and calculate parameters describing the induced etched proton tracks in the CR-39 material was previously developed(( 1)). This code was used to understand the mechanisms involved during interactions with neutrons in the CR-39 material and the influence of the etching process, enabling an improvement in the efficiency of the ...

in this paper we consider contact cr-warped product submanifolds of the type $m = n_ttimes_f n_perp$, of a nearly kenmotsu generalized sasakian space form $bar m(f_1‎, ‎f_2‎, ‎f_3)$ and by use of hopf's lemma we show that $m$ is simply contact cr-product under certain condition‎. ‎finally‎, ‎we establish a sharp inequality for squared norm of the second fundamental form and equality case i...

Human epidermal cells grown in culture synthesize abundant keratins. These keratins are similar to those of stratum corneum of human epidermal callus in their insolubility in dilute aqueous buffers, their molecular weight range of 40,000 to 60,000, their immunological reactivity, and their ability to assemble into 80 A tonofilaments in u&-o; but there are differences in the molecular weights of...

The effect of fluoride-containing orthodontic resin bonding systems on acid resistance of adjacent enamel was evaluated using transversal microradiography. Four fluoride-containing orthodontic resin bonding systems: BeautyOrtho Bond (BO), BeautyOrtho Bond+Salivatect (BOS), Kurasper F (KP), Transbond XT (TB) and a resin-modified glass-ionomer (Fuji Ortho LC (FO)) were used. Superbond Orthomite (...

An attempt was made to sustain the release of Betahistine hydrochloride by complexation technique using strong cation-exchange resin, Tulsion T344. The drug loading onto ion-exchange resin was optimized for mixing time, activation, effect of pH, swelling time, ratio of drug : resin, and temperature. The resinate was evaluated for micromeritic properties and characterized using XRPD and IR. For ...

The present study was to prepare a gastro retentive drug delivery system of Losartan floating tablets, was designed to increase the gastric residence time, thus prolong the drug release. The different type formulations were prepared by using polymers like HPMC K100M, ethyl cellulose, talc and lactose. In the present study Sodium bicarbonate and citric acid were incorporated as a gas generating ...

We study the minimality of an isometric immersion of a Riemannian manifold into a strictly pseudoconvex CR manifold M endowed with the Webster metric (associated to a fixed contact form on M), hence formulate a version of the CR Yamabe problem for CR manifolds-with-boundary. This is shown to be a nonlinear subelliptic problem of variational origin.
