The subjects of heat transfer and cooling system are very important topics in the Internal Combustion Engines (ICE). In modern cooling systems, low weight, small size and high compactness are the critical designing criteria that requires heat transfer enhancement. Boiling phenomenon which is occurred in the water jacket of the ICE is one of the methods to increase heat transfer in the coolant s...

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...

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.

The classic two-state exothermic continuous stirred tank reactor (CSTR) is known to exhibit complex static and dynamic nonlinear behavior, which includes input and output multiplicities, hys-teresis (ignition/extinction behavior), parametric sensitivity, and nonlinear oscillations. An implicit assumption of the two-state CSTR model is that cooling jacket temperature is the manipulated input (fo...

in this contribution, linearized dynamic model of cumulative mass fraction (cmf) of potassium nitrate-water seeded continues mixed suspension mixed product removal (cmsmpr) crystallizer is approximated by a simplified model in frequency domain. frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. however, the cmf fr...

in this paper, optimization and control of a tubular reactor for thermal bulk post-polymerization of styrene have been investigated. by using the reactor mathematical model, static and dynamic simulations are carried out. based on an objective function including polymer conversion and polydispersity, reactor optimal temperature profile has been obtained. in the absence of model mismatch, desire...

As an important contribution to the fulfilment of renewable energy targets, offshore wind sector in Europe has grown significantly over past decade (WindEurope 2021). Jacket structures are becoming more widely used as substructures for turbines accommodate expansion towards greater water depth and provide a stable basis megastructures with hub heights than 200 m. However, there have been few st...

Decommissioning offshore platforms present unique safety and health challenges to the oil gas industry. In Malaysian waters, there are over 300 fixed jacket platforms, most of them exceeded design service life 25 30 years. One key that determine method removal aged is subsea cutting techniques. As underwater a challenging expensive task, it very much essential develop cost-effective techniques ...

Steel monopiles, jackets requiring four steel pinpiles, and gravity-based foundations were applied in offshore wind farms in the Belgian part of the North Sea. This paper compares the underwater noise generated during the piling activities of steel monopiles at the Belwind wind farm (Blighbank) with that of jacket pinpiles at the C-Power project (Thorntonbank). Underwater noise was measured at ...
