Filling defects are often observed on 99mTc sulfur colloid liver scans. Hot spots are much less frequently seen. Superior vena cava syndrome is the most frequent cause of this finding. In this report 3 patients with S.V.C and budd - Chiari syndrome with HOT SPOT on liver scan are presented. Mechanisms of scintigraphic patterns are reviewed.

Recently, a novel environmental stress index (ESI) which is composed from commonly used meteorological variables: ambient temperature (T(a)), relative humidity (RH), and solar radiation (SR) was suggested as follows: ESI = 0.63T(a)-0.03RH+0.002SR+0.0054(T(a) x RH)-0.073(0.1+SR)(-1); (degrees C) The purpose of the present study was to evaluate and validate the ESI for hot dry and hot wet climati...

Although Unibase cream has been an effective medium for electrodermal recordings, its production has recently been discontinued. This study compared alternative media to Unibase for effectiveness. Three base creams similar to Unibase were initially compared for in vitro viscosity and effectiveness. Based upon this analysis one cream was eliminated. A volunteer sample of 6 postmenopausal women w...

The paper provides an overview of our research being performed in the area of interfaces for e-learning, with the emphasis on application of intelligent methods. We especially address the efforts being done in providing a suitable interaction for a class of intelligent e-learning systems – Intelligent Tutoring Systems (ITSs), within the research framework of our home institutions. The specific ...

Background: The severity of wildland fires is increasing due to continually hotter and drier summers. Firefighters are required to make life altering decisions on the fireground, which requires analytical thinking, problem solving, and situational awareness. This study aimed to determine the effects of very hot (45°C; HOT) conditions on cognitive function following periods of simulated wildfire...

Hot electron temperatures and electron energy spectra in the course of interaction between intense laser pulse and overdense plasmas are reexamined from a viewpoint of the difference in laser wavelength. The hot electron temperature measured by a particle-in-cell simulation is scaled by I rather than Iλ at the interaction with overdense plasmas with fixed ions, where I and λ are the laser inten...

The collisional effects on the kinetics of interactions between a high-power subpicosecond laser and a solidcarbon thin film in a fast-ignition scenario are investigated by one-dimensional particle-in-cell simulations. Collisions are found to play an essential role in energy absorption and transport, compared to collisionless cases. In the collisional cases, the absorption at the heating edge, ...

Conclusions The dopingless (DL) JLFET has recently been proposed as a potential candidate that relaxes the requirements of high work function of gate metal electrode and heavy doping throughout from source, channel and drain regions.  Previous studies revealed that the DL-JLFET shows better immunity towards process variation induced random dopant fluctuations in contrast with conventional JLF...

bananas of long cavendish variety constituted the experimental samples in this research work. following the slicing of bananas, the samples were treated with three pretreatments of: 1% sodium bisulphate (t1), a combination of blanching and 1% sodium bisulphate treatment (t2), combined blanching and treatment with 1% ascorbic plus citric acid (1:1) mixture (t3) as well as an untreated sample, co...
