Hagemann (Muench. Med. Wochschr. 85:1066, 1938) discovered that tubercle bacilli have selective affinity for phenol-auramine stain. Since then, several investigators (Richards, Kline, and Leach, Am. Rev. Tuberc. 4:255, 1941; Bogen, Am. Rev. Tuberc. 4:267, 1941; Lempert, Lancet 2:818, 1944; Gray, Am. Rev. Tuberc. 68:82, 1953; Kuper and May, J. Pathol. Bacteriol. 79:59, 1960) have advocated its u...

The goal of this study was to determine the removal efficiencies of chromium, copper, lead, nickel, and zinc from raw wastewater by chemically enhanced primary treatment (CEPT) and to attain a total suspended solids removal goal of 80%. Operating parameters and chemical doses were optimized by bench-scale tests. Locally obtained raw wastewater samples were spiked with heavy metal solutions to o...

Landfill leachate is an important pollution factor resulting from municipal landfill sites. Physical and chemical processes are the better option for pretreatment or full treatment of landfill leachate. This article presents a combination of pre-treatment method (coagulation and adsorption) for leachate collected from municipal solid waste open dumping site. Physico chemical characteristics of ...

Selective ultrastructural staining of acid mucosubstances in sites containing histochemically identifiable sulfo- and sialomucins has been obtained in fixed cryostat sections with both ferric chloride and colloidal iron solutions. The rectosigmoid region of mouse colon was fixed in glutaraldehyde, formalin, or phosphate-buffered osmium tetroxide, and 40 micro cryostat sections of this material ...

Histidinaemia, an inherited disorder of histidine metabolism, was first described by Ghadimi, Partington, and Hunter in 1961. The principal metabolic pathway for histidine is through urocanic acid and formiminoglutamic acid (FIGLU) to glutamic acid (Fig. 1). Zannoni and La Du (1963) demonstrated that histidase, the enzyme necessary for the conversion of histidine to urocanic acid, was absent fr...

Ferric oxide-containing waterworks sludge can be used to reduce the formation of hydrogen sulfide during anaerobic digestion. The ferric compound is reduced biochemically in digester and forms insoluble pyrite sludge. Virgin chloride often solve problem. Since 2013, Sydvatten AB has supplied a growing number digestion plants Sweden with ferric-containing dewatered derived from drinking water tr...
