Gel electrofocusing in tubes containing Sephadex
ELECTROPHORESIS, 1984AbstractGel electrofocusing (EF) on Sephadex G‐75, which provides relatively non‐restrictive pore sizes and relatively broad protein concentration distributions (which reduces concentration‐dependent aggregation), was adapted for use in glass tubes. This allows for EF with meticulously controlled low temperatures in conjunction with large sample and ...

Cotton embryogenesis: the tube-containing endoplasmic reticulum
Journal of Ultrastructure Research, 1968The egg, zygote, and young embryo of cotton possess a tube-containing ER. The tubes are 290–310 A in diameter, microns in length, crooked, and branched. They are preserved with either GaOs or KMnO 4 . The ER within which they occur has attached ribosomes.

Closed Crystalline Tubes as a Container System
Chemical Engineering & Technology, 2010AbstractHollow crystalline glucose anhydrate needles are produced based on a technique to produce hollow crystal needles by phase transformation of solvate crystals into non‐solvates. The fascinating characteristic of the glucose anhydrate needles is the possibility of closing them by a simple drying process.

An Improved Pilot Tube for Plastic Blood Containers
New England Journal of Medicine, 1956MANY hemolytic transfusion reactions can be shown to have been due to human fallibility. For example, pilot or specimen tubes may be wrongly labeled; serial numbers may be misread, or blood intende...

The bursting of tubes containing gas discharges
British Journal of Applied Physics, 1962During a study of thermal shock effects produced on brittle materials by an intense gas discharge of 20 μsec duration, breakage of specimens and bursting of tubes sometimes occurred. Observations have been made of the conditions under which these effects occur. Changes in strength and erosion of materials by the discharge were also studied.

Stainless steel tube-based cell cryopreservation containers
Cryobiology, 2013This study focused on increasing the freezing rate in cell vitrification cryopreservation by using a cryopreservation container possessing rigid mechanical properties and high heat-transfer efficiency. Applying a fast freezing rate in vitrification cryopreservation causes a rapid temperature change in the cryopreservation container and has a ...

Prediction of the expansion of fluidized beds containing tubes
Chemical Engineering Science, 1991Abstract In a fluidized-bed combustor one technique to reduce the output while retaining the bed temperature constant is to uncover tubes near the surface of the bed as the superficial velocity is descreased. A prediction of the bed expansion has been developed which is based on a first-principles model of gas flow through the bed.

The human Fallopian tube contains placental protein 5
Human Reproduction, 1989Placental protein 5 (PP5), a glycoprotein with properties of a serine protease inhibitor, was found in human Fallopian tubes removed during proliferative (n = 6) and secretory (n = 6) phases of the menstrual cycle. The content of PP5 did not differ in fimbrial, ampullar and isthmic parts of the tube.

SULPHUR CONTAINING SEDIMENTS INFLUENCED WEAR OF SUPERHEATER TUBES
Corrosion Reviews, 1996Abstract The failed superheater tube was investigated at the point of failure and at a distance of 25 cm. At both of the cross sections two layers of sediment were detected. The external one contained Na2SO4 and Na3VO3 in concentration relation 6.4:1 approximately.
