2060-T8 Al-Li alloy was friction stir butt welded under natural and water cooling conditions.Microstructures and mechanical properties of the welding joints were mainly compared and discussed.By spraying water on the top surface of stir zone, the grain size was reduced, attributing to the improvement of microhardness.The maximum tensile strength un
Scrub typhus is a life-threatening, undifferentiated febrile illness caused by a gram-negative bacterium, Orientia tsutsugamushi.The bacterial strain is a global health concern that should be considered.Despite several years of effort for the development of an effective immunogenic vaccine, no successful licensed vaccine is available.The aim of the
Introduction: Cold Weather Gear In this paper, we consider LVL (laminated veneer lumber with unidirectional veneer) as an element of plane trusses and geodesic domes, acting as the bearing structure of roofs, and study destruction of LVL joints, which is necessary to improve designs of wooden roofs under consideration.Methods: Our studies were base
[First lines] It is very difficult to operate within the plantation economy paradigm (Best 1968; Beckford 1972; Girvan 1973), and treat history as subject to change.This was the substance of my critique in my article in NWIG 68 (pp.77-99).lts empirical subject matter dealing with Cold Weather Gear the lived experiences of smallholders (popular
