PURPOSE To review, compare, and contrast recovery of potency after robot-assisted radical prostatectomy with specific regard to thermal and excisional nerve injury. Our goal was to compare intensity of injury and ability to recover potency in order to stratify risk by injury type. METHODS We compare potency outcomes in our first 500 consecutive cases of robot-assisted radical prostatectomy. T...

The use of shape memory polymer composites is growing rapidly in smart structure applications. In this work, an active asymmetric composite called "controlled behavior composite material (CBCM)" is used as shape memory polymer composite. The programming and the corresponding initial fixity of the composite structure is obtained during a bending test, by heating CBCM above thermal glass transiti...

Activated carbon is known to adsorb aqueous Hg(II). MPAC (magnetic powdered activated carbon) has the potential to remove aqueous Hg to less than 0.2 μg/L while being magnetically recoverable. Magnetic recapture allows simple sorbent separation from the waste stream while an isolated waste potentially allows for mercury recycling. MPAC Hg-removal performance is verified by mercury mass balance,...

An important aspect of geothermal resource assessment methodology is the development of geothermal resource models consistent with the production histories of exploited geothermal fields. The primary method applied in past United States Geological Survey (USGS) assessments was the volume method, in which the recoverable heat is estimated from the thermal energy available in a reservoir of unifo...

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

The thermal and solvent tolerance of enzymes is highly important for their industrial use. We show here that the enzyme lipase from Rhizopus oryzae exhibits exceptionally high thermal stability and high solvent tolerance and even increased activity in acetone when immobilized onto a graphene oxide (GO) nanosupport prepared by Staudenmaier and Brodie methods. We studied various forms of immobili...

This paper presents the modeling and control of a waste heat recovery system for a Euro-VI heavy-duty truck engine. The considered waste heat recovery system consists of two parallel evaporators with expander and pumps mechanically coupled to the engine crankshaft. Compared to previous work, the waste heat recovery system modeling is improved by including evaporator models that combine the fini...

We consider parallel computing technology for the thermal simulation of multicomponent, multiphase fluid flow in petroleum reservoirs. This paper reports the development and applications of a parallel thermal recovery simulation code. This code utilizes the message passing interface (MPI) library, overlapping domain decomposition, and dynamic memory allocation techniques. Its efficiency is inve...

A thermal asperity detection and recovery scheme for a disk-drive read channel is presented. The circuit design and simulation results for two key blocks, the AC coupler and its tuning loop, in a 0.5μm CMOS process are described.

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
