method of decontaminating waste liquors
contaminants are removed from waste liquor particularly in a closed recirculatory system by adding a soluble silicate to the contaminated waste liquor in an amount sufficient to flocculate the contaminants then, the liquid is treated to separate the flocculated contaminants therefrom. other features for enhancing flocculation of the conta..
phase 2 of the array automated assembly task for the low cost solar array project. quarterly report no. 6, january 1-march 31, 1979
using silk screened evaporated and sputtered al as the metal source, the formation of al back surface fields (bsf) was studied. the most satisfactory results were those obtained with the sputtered al and in which open circuit voltages (v/sub oc/) of 0.585v (12 omega cm fz silicon) have been achieved. the ultrasonic interconnect process is..
health hazard evaluation determination report no. 79-64-593, pennsylvania social services union, philadelphia, pennsylvania,
atmospheric sampling was conducted in and around the offices of the pennsylvania social services union in philadelphia, pennsylvania to evaluate reported airborne exposures of xylene (1330207) vapors and other solvent odors emanating from an adjacent building occupied by rich-art graphics, a silk screen printer. the evaluation was request..
syncrisis: the dynamics of health. an analytic series on the interactions of health and socioeconomic development. ii: honduras,
this study has found that a comprehensive integration of the resources that honduras has at hand surely would help the country break out of its circular dilemma of disease-poverty-disease. that the major diseases from which the population suffers - malaria, intestinal parasitism, malnutrition, and respiratory diseases - are preventable an..

this bibliography contains citations concerned with the control of working atmospheres in the rubber and plastics industries to prevent respiratory and epidermal ailments from employees. monitor techniques and contamination removal systems are described for such dust emitting materials as colorants, pigments, dyes, glass fibers, ceramic d..
low-cost process for p-n junction type solar cell. final report, september 1, 1980-february 28, 1981
low-cost manufacturing methods have been studied for two types of thin-film solar cells on glass substrates. one is a heterojunction cds/cuinse sub 2 deposited by chemical spray pyrolysis; the other is a cds/cdte cell that is prepared by silk screening and sintering. in the spray pyrolysis program, we have succeeded in deposition cds laye..
