For the past three years, usually during the summers, she has been lugging step ladders, temperature loggers, and aspirators — metal-and-plastic assemblies of tubes, piping, and a jar, to suck up individual ants off the dirt — across the city's parks, sidewalks, and intersections, and up into street trees.
A conductor found a package containing an assembly of tubes, wiring and a small amount of explosive powder about 10 a.m. as the train was at the outskirts of the city, the Rome transport agency said in a statement.
With 650 rounds pumped out a minute, Kalashnikov's cheap and cheerless, charismatic assembly of tube and wood has, with added global trickle-down, put mass slaughter inside the budgets of ordinary Joes - and Abdullahs and Reiks - everywhere.
As shown in Fig. 6a c, the strategy mentioned in this paper can be directly applied to self-assembly of tube structures.
After the lift-off process, reactive ion etching with CF4/O2 was used to induce Sn grain coalescence and realize the assembly of tube structures.
Three dimensional hydraulic analysis of single isolated shroud tube and integrated assembly of shroud tubes have been carried out using CFD tools to acquire this knowledge.
RAS LAFFAN INDUSTRIAL CITY, Qatar — The compact assembly of towers, tubes and tanks that make up the Oryx natural gas processing plant is almost lost in a vast petrochemical complex that rises here like a hazy mirage from a vast ocean of sand.
For the present study we use a cylindrical assembly of two tubes.
The complete formation of a lumen in novel sprouting vessels needs the contribution of stalk cells, stimulated by VEGF, ECM, and EC-derived EGF-like domain 7 (Egfl7), which promotes the separation and proper spatial arrangement of the angioblasts and allows subsequent assembly of vascular tubes [ 19].
At the O2/CF4 ratio of 0.5, the vertical to horizontal etching rate ratio is 1, which cannot accumulate enough energy to self-assembly of the tube before releasing it form the substrate, resulting in ununiformed partially folded tube structure (Fig. 6c, d).
