Epithelia act in the organism as biological barriers. All of them are exposed to different environments at the luminal and basal side. To simulate such a tissue-specific situation Minusheet ® gradient perfusion culture was developed. For pharmaceutical research, biomaterial testing and tissue engineering epithelial cells are cultured on individually selected supports (1). Growing epithelia are ...

<em>The purpose of this research is to describe the spatial aspects conceptualization generated by dominant metaphors found in Acehnese society both related culture and nature. The author uses Lakoff Johnson's (1980) cognitive semantic conceptual study which clarified Cruse & Croft (2004) Saeed (2009) describing analyzing data. concept space refers container (container) place (spa...

medium were placed in culture tubes (16 by 150 mm). A layer of mineral oil 1 cm deep was placed on the surface of the medium, and the tubes were stoppered with cotton plugs. The tubes were then placed in an autoclave and heated for 15 min at 15 lb per in.2 During autoclaving, the culture tubes were tilted at a 200 angle to increase the exposed surface area; this reduced the problem of the mediu...

In the first part of this paper we study minimal representations of simply connected simple split groups G of type Dk or Ek over local nonarchimedian fields. Our main result is an explicit formula for the spherical vectors in these representations. In the case of groups over R and C, such a formula was obtained recently in [8]. We also use our techniques to study the structure of the space of s...

The mp3 lies at the center of important debates around intellectual property and file-sharing, but it is also a cultural artifact in its own right. This article examines the design of the mp3 from both industrial and psychoacoustic perspectives to explain better why mp3s are so easy to exchange and the auditory dimensions of that process of exchange. As a container technology for recorded sound...

The two well known techniques which are used in plant-nutrition studies are conveniently designated the solution-culture method and the sand-culture method. Some other slightly soluble materials, such as cinders, gravel, vermiculite, and Sponge Rok or various combinations of these may be substituted for sand. The use of slightly soluble material as a medium, to which the nutrient solution is pr...

This study analyses the concept of cost functions for semi-automated Straddle Carrier (SC), Rubber Tyred Gantry (RTG) and automated Rail Mounted Gantry (RMG) container yard operating cranes. It develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

Pooled specimens from the urethra and cervix accounted for 97% of 101 positive chlamydial isolations in 332 women, and this yield compared favourably with the individual yield from either the urethra (77%) or the cervix (88%). Pooling specimens caused no apparent increase in toxicity to the cell culture system. These results indicate the advantages, in terms of higher yield and no higher cost, ...
