In another paper [1914] an account will be found of a new method for the estimation of aspartic and glutaminic acids in the hydrolytic products of proteins, depending upon the insolubility of their calcium salts in alcohol. In studying the influence of lime upon glutaminic acid in aqueous solution at higher temperatures it was found that the amino-nitrogen content had been considerably reduced....

-An automated system for the analysis of dissolved organic nitrogen has been developed and applied to natural waters. It is based on subjecting sample to u.v. irradiation followed by a heterogeneous reduction of the nitrogen containing irradiation products to ammonia which is detected by an ammonia gas sensing probe. Quantitative recoveries of different organic nitrogen compounds common to natu...

NEffBOLEPTANAL6ESIA (NLA) has been practiced in Europe since 1959, and today the largest personal series exceed 10,000 cases, z The anaesthetic aims at providing psychomotor sedation while leaving cortical and homeostatic hmctions as intact as possible. ~ At the present time this selective action is achieved by the use of two agents, droperidol and fentanyl. These are given intravenously and ma...

This study examines polybrominated diphenyl ethers (PBDE) levels, trends in biosolids from a wastewater treatment plant, and evaluates potential factors governing PBDE concentrations and the fate in agricultural soils fertilized by biosolids. The mean concentration of the most abundant PBDE congeners in biosolids ( summation operatorBDE-47, BDE-99, and BDE-209) generated by one wastewater treat...
