In the performance of a transvascular liver biopsy, the Trucut-type transjugular liver biopsy set is advance over a multipurpose catheter place in the suprahepatic vein. Occasionally there is a sharp bend between the suprahepatic veins and the inferior vein cava and the multipurpose catheter does not provide sufficient support to track the biopsy access set. To deal with this problem we describ...

The aim of this paper is to study the integration of multiplicative preference relation as a preference representation structure in fuzzy multipurpose decision-making problems. Assuming fuzzy multipurpose decision-making problems under di4erent preference representation structures (ordering, utilities and fuzzy preference relations) and using the fuzzy preference relations as uniform representa...

Aqueous biphasic catalysis is a convenient approach to convert organic, partially soluble molecules in water. However, converting more hydrophobic substrates is much more challenging as their solubility in water is extremely low. During the past ten years, substantial progress has been made towards improving the contact between hydrophobic substrates and a hydrophilic transition-metal catalyst....

This paper argues that Information Technology (IT) needs to be demystified, through critical consciousness, for educators to focus on IT as a means to enhance learning. It goes on to define the technical, sociohistorical and political-ideological levels of IT and to identify four theoretical constructs: tutorial, machine-as-human, tool kit and catalyst. Pervading these constructs is the underst...

PURPOSE To evaluate the safety and efficacy of the porous polyethylene multipurpose conical orbital implant for use in evisceration. METHODS A retrospective review of 31 eyes that underwent evisceration and received the multipurpose conical orbital implant. The orbits were evaluated at 1 week, 1 month, and 6 months after final prosthetic fitting for implant exposure, superior sulcus deformity...

This paper is an investigation of completely mechanical quick changeable joints for multipurpose explosive ordnance disposal (EOD) robots. With the assistance of a quick changeable joint, an ordinary EOD robot becomes a multipurpose robot with an end effector which can be switched during the task. This exchangeable end effector permits the robot to perform more complex duties. Making the joint ...

The super-Brownian motion X % in a super-Brownian medium % constructed in DF96a] is known to be persistent (no loss of expected mass in the longtime behaviour) in dimensions one ((DF96a]) and three ((DF96b]). Here we ll the gap in showing that persistence holds also in the critical dimension two. The key to this result is that in any dimension (d 3); given the catalyst, the variance of the proc...

This paper describes a knowledge-based useroriented interface system which is unique in its combined use of data base, graphics, and AI technologies. All of the data presented to the user, as well as all of the data input by the user, is maintained and used as abstract “objects” using an AI object-oriented knowledge representation approach. However, the system employs a relational data base as ...
