Recent studies majored their investigation on the history and symbolism of indigenous fabrics, with little or no information on the distinguishing elements in the materials, tools, equipment and techniques employed across the communities engaged in the craft. This study seeks to unearth these ...
Independently of the technology employed, the obtained films exhibited high contact angle value (larger than 150°), but while the acrylic polymers presented strong demoulding drawbacks, the polydimethylsiloxane (PDMS) films had good properties in terms of both contact angle and optical transparency. ...
A range of other materials was employed in the task of the writing of letters: pens and penknives for cutting and re-cutting quills; feathers of varying types to turn into quills; ink for writing with and its accoutrements, an inkpot or inkhorn for holding the ink, a dust box, sand ...
traditional CRISPR/Cas genome editors; (2) remodeling gene roles by precisely modifying specific nucleotide base sequences, which preferably uses base editor and prime editor; and (3) modulating gene expression, in which CRISPR/Cas-based gene activation and repression approaches are usually employed....

Twelve parameters have been selected as shape parameters on the clinching tools such as punch and die. The design of experiments (DOE) method is employed... JY Kim,CJ Lee,SK Lee,... - 《Transactions of Materials Processing》 被引量: 18发表: 2009年 ...
The annular BOP is the most employed unit by the drilling industry. Two designs now available - stripper-type units and metal reinforced packing unit preventers - incorporate closing-off and controlling qualities for offshore emergencies. Created specifically for underwater operations, ram-type BOPs ...
Powder metallurgy plays a role in manufacturing such as automotive and cutting tool applications. Diamond/cemented carbide tools are also made from this technique. Diamond particle and other matrix materials were employed in this study. The purpose is to investigate the physical and mechanical propertie...
The unique characteristics of ultrafast lasers, such as picosecond and femtosecond lasers, have opened up new avenues in materials processing that employ ultrashort pulse widths and extremely high peak intensities. Thus, ultrafast lasers are currently used widely for both fundamental research and practica...
reuse. By entering a streamlined set of project information, such as energy targets and potential building interventions, users can quickly estimate both operational carbon emissions generated by the use of the building and embodied carbon emissions, which are tied to the building materials employed. ...
