Introduction to quantitative chemical analysis (Grunwald, Ernest; Kirshenbaum, Louis J.)

Reviewing the results of qualitative and quantitative analysis of MCQs in Introduction to clinical medicine course

Background: At most of the medical universities, MCQ-based examinations are often use as the first component, particularly to ensure the candidates have an adequate knowledge base, prior to entering subsequent clinical examinations. Method: In ICM , 3973 MCQs were collected from tests over a four-year period from 2005 to2009. Questions were evaluated for 10 frequently occurring item writing f...

In Memoriam: Louis J. Guillette, Jr.

Louis (Lou) J. Guillette, Jr., one of the most influential research scientists in the field of environmental health, died 6 August 2015 at the age of 60. Lou had been battling non-Hodgkin’s lymphoma for almost a decade, but his passing, caused by bacterial pneumonia, came as a shock to everyone who knew him. He was an extremely energetic man with a passion for the natural environ ment. He revel...

Grunwald-Winstein Analysis - Isopropyl Chloroformate Solvolysis Revisited

Specific rates of solvolysis at 25 degrees C for isopropyl chloroformate (1) in 24 solvents of widely varying nucleophilicity and ionizing power, plus literature values for studies in water and formic acid, are reported. Previously published solvolytic rate constants at 40.0 degrees C are supplemented with two additional values in the highly ionizing fluoroalcohols. These rates are now are anal...

An Introduction to Signal Processing in Chemical Analysis

The interfacing of analytical instrumentation to small computers for the purpose of online data acquisition has now become almost standard practice in the modern chemistry laboratory. Using widely-available, low-cost microcomputers and off-the-shelf add-in components, it is now easier than ever to acquire data quickly in digital form. In what ways is on-line digital data acquisition superior to...
