monitoring techniques for carbon fiber emissions: evaluation b

an evaluation of available measurement methods for continously monitoring the number and mass of carbon fibers emitted from source operations was conducted. a total of eleven candidate monitoring methods were identified based on contact (electrical), locally sensing (optical, microwave) and remote sensing (microwave, radar) each method wa..

evaluation of candidate materials for silhouette layout mat (slm) for general mechanics tool kit

the purpose of the work was to find a material with suitable durability, acceptable color contrast, and good printability for fabrication of silhouette layout mats to be used as inventory aids for army tool sets, kits, and outfits. six different materials were chosen for engineering evaluation based on technical assessment of high success..

securing containerized hazardous wastes by encapsulation with spray-on/brush-on resins

methods were investigated for securing containerized hazardous wastes in the field with spray-on or brush-on resins at ambient temperatures. laboratory-scale, cylindrical specimens of containerized sodium chloride (which simulated soluble salts containing heavy metals) were fabricated 63.5 mm in diameter by 88.9 mm high (2.5 by 3.5 in.). ..
