Sir John Cornforth AC CBE FRS: his synthetic work

Sir John Cornforth’s work on the synthesis of cholesterol and penicillamine, on the chemistry of oxazoles, the stereochemistry of the synthesis of alkenes, the synthesis of abscisic acid and of dibenzophospholes as mimics of enzyme action, is reviewed

Idaho National Engineering Laboratory In Situ Vitrification Project FY-91 progress report

The purpose of this report is to present an overview conducted under the In Situ Vitrification (ISV) Project at the Idaho National Engineering Laboratory (INEL) during the 1991 Fiscal Year. The report will concentrate on describing the activities being conducted by the ISV project at the INEL and the advances made in this project at the INEL and the advances made in this project during FY 1991. Because detailed descriptions of the ISV process are available elsewhere (Arrenholz et al. 1990, Callow et al. 1991a), this discussion will not be repeated here

Technical issues associated with in situ vitrification of the INEL Subsurface Disposal Area

In situ vitrification (ISV) has been identified as an alternative technology for remediation of the Acid Pit and Transuranic Pits and Trenches (TRU-PTs) that are present at the Idaho National Engineering Laboratory (INEL) Subsurface Disposal Area (SDA). However, a number of technical issues exist that must be resolved before ISV can be considered applicable to these waste sites. To assist in the ISV technology evaluation, an ISV Steering Committee was formed to identify, prioritize, and develop closure roadmaps for technical issues associated with ISV application at the INEL SDA. The activities of the ISV Steering Committee are summarized in three volumes of this report. This document, Volume 1, identifies the systematic approach used to identify and prioritize the ISV technical issues, and briefly discusses the methodology that will be employed to resolve these issues

This document Volume 2 and Volume 3 discusses each technical issue in greater detail and suggest specific closure roadmaps to be used in resolving technical issues associated with ISV at the SDA Acid Pit and TRU-PTs, respectively

Estudo das glândulas mandibulares e ovários de operárias de Apis mellifera L. (Hymenoptera, Apidae) mantidas em condiçoes artificiais

Foram estudados os ovários e as glândulas mandibulares de Apis mellifera mantidas em condições artificiais e foi observado que em pequenos grupos (menos de 20 abelhas) os órgãos analisados não se desenvolveram.<br>The ovaries and mandibular glands in workers of Apis mellifera under artificial conditions were studied and was observed that in small groups (less than 20 bees) the analyzed organs did not develop
