Meet the Head Coach Head Coach Scott Virgulak Scott Virgulak begins his second year as Rhode Island College's head baseball coach. He guided the Anchormen to a 21-18 overall record, the program's fourth straight 20-win campaign, and an 8-6 (third place tie) mark in the Little East Conference in his first season at the helm in 2010. He spent 2004-09 as an assistant coach under previous RIC boss Jay Grenier. During his time as an assistant, he primarily worked with the team's position players, while serving as the squad's third base coach during games. Off the field, he was instrumental in working with the team's recruiting efforts. Virgulak was an assistant coach with the Newport Gulls of the New England Collegiate Baseball League (NECBL) from 2006-09. The Gulls captured the 2009 NECBL Championship, with Virgulak serving as the head coach during the deciding game in the playoffs. Virgulak was an assistant coach for the 2009 NECBL All-Star squad that played Team USA. He also was an assistant coach during the 2004, '05 and '06 NECBL midsummer classics. Prior to joining the Gulls staff, Virgulak was an assistant coach with the North Adams Steeplecats and was promoted to head coach during the 2005 season, leading the club to its first and only playoff series victory. He played two seasons of baseball at RIC in 2000 and 2001. The North Kingstown, Rhode Island native played in 59 games, starting 58 of the them. He posted a .286 career batting average with 43 runs, 61 hits, 33 RBI, 16 doubles, five home runs, 92 total bases, 33 walks and one stolen base. He recorded a .432 slugging percentage, a .382 on-base percentage and a .938 fielding percentage for his career. As a junior in 2000, Virgulak had an outstanding season and was named First Team All-Little East Conference at third base. He batted .377 with 24 runs, 43 hits, 16 RBI, 10 doubles and two home runs. Prior to coming to RIC, Virgulak played two seasons for Grenier at the Community College of Rhode Island.
perators... are increasingly recognizing the need for a systematic assessment and management of flexible pipe integrity, but the identification of critical criteria and the means to best achieve valid and efficient inspection and monitoring (I&M) continues to evolve. Emerging technologies in I&M and operators’ expanding implementation of riskbased management are leading the way toward achieving a comprehensive integrity management approach for flexible pipeline and riser systems worldwide. Flexible pipes are being installed and operated in more marginal and challenging offshore conditions, adding to the complexity of acquiring complete and valid data for the determination of their integrity. Especially important is the accurate assessment of the remaining life of a flexible riser so operators can avoid costly premature change outs. To further develop the definition of best practices in flexible pipe integrity assurance, the SureFlex Joint Industry Project (JIP) presented key findings from its extensive 20-month-long survey work, including flexible pipe use worldwide, statistics on design limits, damage, and failure incidences. Conducted under the auspices of the Oil and Gas UK, a trade association for the United Kingdom upstream oil and gas industry, the “State of the Art Report on Flexible Pipe Integrity and Guidance Note on Monitoring Methods and Integrity Assurance for Unbonded Flexible Pipes (2010)” revisited the state of flexible pipe since the first survey in 2001 to 2002. The scope of work was international in its content and had the support of international companies outside of the UK.

Numerical techniques based on pressure-velocity formulation have been adopted to solve approximately, the governing equations for viscous flows through a tube (simulating an artery) with a periodic constriction. The effect of the constriction as well as the rigid of the tube, on the flow characteristics, and its consequences for arterial disease is the focus of this investigation. The unsteady incompressible Navier-Stokes equations are solved by using the finite-difference technique in staggered grid distribution. The haemodynamic factors like wall shear stress, pressure and velocity are analyzed through their graphical representations. Maximum resistance is attained in case of rigid stenosed tube rather than the flexible one. The main result is to contribute that the recirculating region is larger in case of a rigid tube than that of flexible one. Key words: Periodic constriction, pressure-velocity approach, complaint wall, finite difference scheme MSC 2010 No.: 76D, 74S20 2045

Department of Chemical Engineering, Indian Institute of Science, Bangalore 560 012, India (Received 17 June 1998 and in revised form 25 October 1999) The stability of ﬂuid ﬂow in a ﬂexible tube to non-axisymmetric perturbations is analysed in this paper. In the ﬁrst part of the paper, the equivalents of classical theorems of hydrodynamic stability are derived for inviscid ﬂow in a ﬂexible tube subjected to arbitrary non-axisymmetric disturbances. Perturbations of the form vi = ˜i exp [ik(x − ct) + inθ] are imposed on a steady axisymmetric mean ﬂow U(r) in v a ﬂexible tube, and the stability of mean ﬂow velocity proﬁles and bounds for the phase velocity of the unstable modes are determined for arbitrary values of azimuthal wavenumber n. Here r, θ and x are respectively the radial, azimuthal and axial coordinates, and k and c are the axial wavenumber and phase velocity of disturbances. The ﬂexible wall is represented by a standard constitutive relation which contains inertial, elastic and dissipative terms. The general results indicate that the ﬂuid ﬂow in a ﬂexible tube is stable in the inviscid limit if the quantity UdG/dr > 0, and could be unstable for UdG/dr < 0, where G ≡ rU /(n2 + k 2 r2 ). For the case of Hagen–Poiseuille ﬂow, the general result implies that the ﬂow is stable to axisymmetric disturbances (n = 0), but could be unstable to non-axisymmetric disturbances with any non-zero azimuthal wavenumber (n = 0). This is in marked contrast to plane parallel ﬂows where two-dimensional disturbances are always more unstable than three-dimensional ones (Squire theorem).
The synthetic hoses consist of a seamless PA compound inner layer reinforced with a braided layer of high performance synthetic fibre. This reinforcement is protected by an oil, weather and abrasion resistant Polyester Elastomer Compound. The standard assembly length is 0,9 meter with one straight and one elbow 90 degree hose fitting. The fitting connection is 1/4” metal tube with 7/16”-20 UNF swivel nut connection suitable for 1/4” SAE male flare. Other lengths and/or fitting connections configurations (Style 50, 51 straight or elbow) are available on request (quantity orders only). Features zz Very flexible zz Low minimum bend radius (30 mm) zz One straight and one 90° elbow pressure connection zz Polyester Elastomer Compound construction zz High pressure safety ratio zz Low effusion Application These synthetic hoses are designed for pressure measuring connections.
