Experimental infections of Lymnaea truncatula with a digenean species (Fasciola gigantica, F. hepatica, or Paramphistomum daubneyi) were performed under laboratory conditions to study the effect of four sources of food (microalgae, romaine lettuce, wheat germs, or modified Boray diet) on cercarial production. The mean number of F. hepatica, F. gigantica, or P. daubneyi cercariae was significant...

We discuss the problem of interpolating C Hermite data on the sphere (two points with associated first derivative vectors) by spherical rational curves. With the help of the generalized stereographic projection (Dietz et al., 1993), we construct a two– parameter family of spherical quartics solving this problem. We study the shape of these solutions and derive criteria which guarantee solutions...

BACKGROUND Fistula failure has been classified as early and late. Early failure refers to those cases in which the arteriovenous (AV) fistula never develops to the point that it can be used or fails within the first 3 months of usage. It has been common practice to abandon these early failures; however, aggressive evaluation and treatment of early fistula failures has been shown to result in th...

Least-Mean-Squares (LMS) based mixed-signal scheme for self-calibration of pipelined Analog-Digital Converter (ADC) is proposed. The technique uses an elegant continuous reference update algorithm to correct for gain errors and offset errors in a pipeline stage with minimal area and power overhead. Simulation results show the effeciency of the scheme for resolution of greater than 13bits in a C...

Abstract Background Actin is an essential cellular protein that assembles into microfilaments and regulates numerous processes such as cell migration, maintenance of shape, material transport. Methods In this study, we explored the effect actin polymerization state on osteogenic differentiation human adipose-derived stem cells (hASCs). The hASCs were treated for 7 days with different concentrat...

Received Oct 23, 2017 Revised Dec 29, 2017 Accepted Jan 20, 2018 This paper aims to improve the performance of the traditional routing protocol for MANET such as DSR and AODV in terms of delay and overhead. The proposed routing scheme is called as Extremely Vibrant Routing (EVR) which adopts with the highly dynamic environment of MANET. The link residual life is estimated to reduce the link fai...

This paper shows how agent-based modelling technique is a suitable approach for social scientists to model complex adaptive systems , using computer as experimental environment. Unfortunately advanced tools are lacking as well as an unified language supporting its development. We present JAS, a new agent-based simulation tool, developed with the aim to improve AB models designing. We give a bri...

(Prom the School of Tropical Medicine, Calcutta) In a previous paper it was observed by one ? us (Basu and Bose, 1941) that although the toxicity (LD/50) of 2-chloro-7-methoxy-5 (8c lethyl-amino-butyl) amino-acridine, in mice, Jas only slightly higher than that of 2-chloro~n}ethoxy-5 (8-diethyl-amino-iso-amyl) aminoacndine, the toxic effect of the former on cultures of Paramecium caudatum was f...
