development of a numerical model which describes launching of offshore jackets from barge is presented in this paper. in this model, in addition to capabilities of commercial softwares, water entry forces on jacket members and an implicit newmark solution technique are included. the results are in general agreement with other numerical software’s available (sacs). fluid forces acting on jacket ...

− A new controlled-clearance pressure balance has been developed to improve the hydraulic pressure standard for pressures up to 1 GPa. For several controlledclearance piston-cylinders, characterization experiments based on the Heydemann-Welch model were performed to estimate the effective area of them. The results for the piston-cylinders of different pressure ranges are exemplified in this pap...

This paper presents an analytical model to construct the interaction diagrams (normal force and moment) for RC column strengthened using steel jacket technique. The proposed is defined strain distribution block by determining location of neutral axis in concrete section. formulation verified experimental results performed previous researches numerical models nonlinear program ANSYS. factors aff...

Coronary stents represent a key development for the treatment of obstructive coronary artery disease since the introduction of percutaneous coronary intervention. While drug-eluting stents gained wide acceptance in contemporary percutaneous coronary intervention practice, further developments in bare-metal stents remain crucial for patients who are not candidates for drug-eluting stents, or to ...

The halo body jacket and plaster Minerva body jacket have been the preferred orthoses when maximal stabilization of the cervical spine is required. This report identifies some disadvantages of these orthoses, introduces the thermoplastic Minerva body jacket (TMBJ), and discusses its advantages in the rehabilitation of patients with cervical spine instability. A preliminary roentgenographic stud...

At present, China's steel industry is experiencing a serious dilemma. The steel companies are trying to achieve a breakthrough and upgrade in the face of adversity with Ebusiness. So Ebusiness has been a long-term development in the steel industry, from version 1.0 to version 2.0, and now it has come to version 3.0. In its version 3.0 resource integration platform, the information release platf...

OBJECTIVES To laparoscopically compare the effectiveness of 2 cooling devices for renal hypothermia and investigate the feasibility of laparoscopic orthotopic kidney transplant using a pig model. MATERIALS AND METHODS Eight pigs were divided into 2 groups of 4 animals each. Laparoscopic nephrectomy and autotransplant were performed first on only the right kidney. One week later, these procedu...

The RONDAN jacket support clamp and jacket transport sled are inexpensive, relatively easily fabricated tools which have proved invaluable for the field collection of large vertebrate specimens. Although there are some complicating factors, both of these tools have been used with great success to safely collect and transport numerous Jurassic dinosaur bones.
