Elionurus hensiiyields essential oils composed mainly of para-menthadienols in its stems and about 50 % aristo lonein its roots. These oils, which exhibit anti-microbial and anti-oxidant properties, were extracted by hydro distillationwith a local extractor and was analyzedby gas chromatography (GC/FID and GC/MS).To optimizethis domestic process, a 23full ...
In coming ye ars, nanotechnology is likely to have a significant impact in different fields like medicine and electronics. Nanorobotics is emerging as a demanding field dealing with miniscule things at molecular level. Nano robots perform a specific task with precision at nanoscale dimensions. Nano robots are especially used for studies on Alzheimer ...
Energy-related buildings and structures are designed to meet safety requirements. The greatest danger is a radiation. In Russia there is an advanced system of regulatory documents, which contain thousands of requirements for radiation and fire safety, and layout solutions. During design and construction it is necessary to use the organizational system of checking and compliance of ...
Experimental investigation of heat transfer for solid and hollow concrete blocks with 2, and 3 evenly spaced cavities in them is explored to determine the most appropriate number of cavity in building blocks for effective energy consumption in building without compromising the strength of the blocks and building. The samples were tested based on their crushing strength and he at flow...
The steel milling AISI 1045 has been gaining prominence in industry in recent years as it allows machined parts to be obtained with low-cost inserts. However, to ensure the final product quality, it is important that the milling for machining procedure be well planned in order to the cutters have their wear minimized in the process, as well as a considerable productivity rate with a ...
