In order to reduce the functional degradation caused by improper daily washing-care and prolong service life of technical jacket, relationship between washing conditions in wearing performance jacket (waterproof, windproof, warmth retention) was quantitatively investigated with help hydrostatic pressure, surface contact angle, air permeability, retention, scanning electron microscopy (SEM) afte...

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 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...

different control strategies of bed temperature and moisture were investigated using various inlet air temperatures and air fluxes in both the ordinary packed bed bioreactor (without cooling water in the jacket) and the bioreactor with cooling water in jacket. the experiments were carried out within a 1-l solid-state packed bed bioreactor in which aspergillus niger was cultivated on wheat bran....

We describe a way to combine the method of fictitious sources and the scattering-matrix method. The resulting method presents concurrently the advantages of these two rigorous methods. It is able to solve efficiently electromagnetic problems in which the structure is made up of a jacket containing an arbitrary set of scatterers. The method is described in a two-dimensional case, but the basic i...

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 ...

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 ...
