fluids for various industrial applications because of their excellent thermal performance. this study analytically and experimentally examines the effects of nanoparticle dispersion on the entropy generation of eg–al2o3 nanofluid flows through a helical pipe as a heat exchanger under constant wall heat flux thermal boundary condition in laminar regime. it is found that adding nanoparticles impr...

The genera Ptaeroxylon and Cedrelopsis have been grouped together by Styles and Pennington into the Ptaeroxylaceae family due to similarity in their morphology and structure of the secondary xylem. The monospeci"c genus Ptaeroxylon had previously been placed in the Sapindaceae, the Rutaceae, and most popularly, in the Meliaceae families. The pollen of Cedrelopsis and Ptaeroxylon are very simila...

Jeffrey S. Flier was named the 21st Dean of the Faculty of Medicine at Harvard University on July 11, 2007, at which point he became the Caroline Shields Walker Professor of Medicine at Harvard Medical School. Flier is an endocrinologist and an authority on the molecular causes of obesity and diabetes. Prior to becoming dean, he served from 2002 to 2007 as Harvard Medical School Faculty Dean fo...

In this paper, a comprehensive numerical study is presented for the fully developed two-dimensional flow of viscous incompressible fluid through a curved duct with square cross section. Numerical calculations are carried out over a wide range of the Dean number 6500 100   Dn for the curvature 5 . 0   . A temperature difference is applied across the vertical sidewalls for the Grashof number ...

A service evaluation of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) testing and result notification in patients attending a rapid testing service (Dean Street Express [DSE]) compared with those attending an existing 'standard' sexual health clinic (56 Dean Street [56DS]), and modelling the impact of the new service from 1 June 2014 to 31 May 2015. PRIMARY OUTCOME time from patie...

In this paper, we present a new analytic model for evaluating average end-to-end delay in IEEE 802.11 multihop wireless networks. Our model gives closed expressions for the end-to-end delay in function of arrivals and service time patterns. Each node is modeled as a M/M/1/K queue from which we can derive expressions for service time via queueing theory. By combining this delay evaluation with d...

Dean has been the Director of Positive Behaviour Strategies Ltd and has been a Principal Tutor for Team Teach since the SEBD School that Dean was working in closed as a result of a restructuring of SEBD provision in Sheffield in 2005. In this article, he describes his research for part of his recent SEBDA/ University of Leicester master's degree. Dean looked at the impact of training in 'positi...
