Thermal resistance and air permeability of jute-polypropylene blended needle- punched nonwoven

Thermal resistance and air permeability of needle-punched nonwoven fabric made from jute and polypropylene blends have been studied using the Box and Behnken factorial design to observe the effect of fabric weight, needling density and blend proportion on thickness, thermal resistance, specific thermal resistance, air permeability and sectional air permeability. Correlation matrix and cluster a...

A punched-card system for the laboratory.

A punched-card system was developed to simplify the administrative aspects of the clinical chemistry laboratory. In it a three-part requisition and samples are matched and given a laboratory number. The third copy of the original laboratory requsition is a charge card also used as a name file for the day. Prepunched cards, coded for laboratory tests, are used for each test requested. The labora...
