The blood flow in rat liver was measured with Xe-133. Three techniques for administering the activity to the liver were employed: injection via the portal vein, via the hepatic artery, and directly into the liver parenchyma. Use of intraparenchymal injection of Xe-133 gave 60% higher flow values than by portal or arterial injection techniques. Mean flow index (k1) was for portal injection 0.52, fo
A computerized system for inducing total body hyperthermia by microwave irradiation was tested in rats. The tolerance to hyperthermia at different temperatures and fractions was studied as well as its effect on the growth of transplanted adenocarcinomas in the liver. Survival results indicated that 41.5 degrees C was maximum tolerated temperature both after single and repeated one hour exposures.
Due to increased awareness of climate change and energy costs, well-insulated buildings have become more common. Furthermore, greater interest has been shown in using wood in building to produce more carbon dioxide-efficient houses. However, thicker thermal insulation in walls increases the risk of high relative humidity levels and the risk of mold-related damage in wood frame houses. This paper
This chapter explores the idea of community of practice in relation to Swedish educational development. Two authentic cases illustrate how faculty developers work together as a CoP to promote change within universities. The two cases and their results are scrutinized in relation to key features of CoP, where one case arguably came out stronger as a CoP mainly in terms of identity building. The tex
The paper presents a revised definition of the mean effective gain (MEG) of terminal antennas. It now includes the gain pattern of both the transmitting (BS) and receiving (MS) antennas, the path gain matrix as well as the joint angular power distributions of the two orthogonal polarizations at both ends. A closed form equation is provided followed by the analysis of some special cases and their p
Returnable transport items (RTI) have increasingly been introduced for environmental reasons and to achieve logistics benefits such as better protection of products, improving working environments, and enabling more efficient handling and cube utilisation. Even though RTI are often of high value, vulnerable to theft, and critical for production and distribution, they are often managed with limited
This study investigates the public reading of New Testament writings in early Christian communities during the first two centuries C.E. from the perspective of the lectors who prepared and performed the readings. A survey of literary and pictorial sources from the Greek and Roman world indicates that only oratory and drama were delivered from memory, whereas most literary writings were read aloud
