Synthesis of SmFeAsO by an Easy and Versatile Route and its Physical Property Characterization [PDF]
We report synthesis, structure, electrical transport and heat capacity of SmFeAsO. The title compound is synthesized by one-step encapsulation of stoichiometric FeAs, Sm, and Sm2O3 in an evacuated (10-5 Torr) quartz tube by prolong (72 hours) annealing ...

CFD Analysis of Thermal Performance in a U-Tube Solar Collector [PDF]
Solar water heating systems have both domestic and industrial applications that are both inexpensive and easy to maintain. In this study, the thermal performance of a U tube evacuated tube solar collector (ETSC's) was evaluated numerically.

The Evolution of Evacuated Blood Collection Tubes [PDF]
“A laboratory test is no better than the specimen, and the specimen no better than the manner in which it was collected.” So stated the advertising language of BD (Becton Dickinson and Company) to promote the first evacuated blood collection tubes, back in the late 1940s and early 1950s.1 This technology for blood collection, patented in 1949, is ...

Magnetohydrodynamic kink waves in two-dimensional non-uniform prominence threads [PDF]
We analyse the oscillatory properties of resonantly damped transverse kink oscillations in two-dimensional prominence threads. The fine structures are modelled as cylindrically symmetric magnetic flux tubes with a dense central part with prominence ...
