This increase in productivity is accounted for partly by a decrease in absenteeism and accidents as well as a general increase in working efficiency. For example, Vernon (1918), found that when women in a munitions factory worked a 12-hour day they incurred 2.5 times more accidents than when they worked a 10-hour day. One of the more comprehensive studies of the effects of total hours of work was carried out after World War II by the U.S. Department of Labor (Kossoris and Kohler, 1947). This covered over 3500 men and women in 78 work units. Data were collected on accidents and absenteeism as well as productivity. The overall findings were that exceeding the 8-hour work day, 5 days/40 hours work week resulted in lower productivity and higher absenteeism and accident rates. 

The cleavage proceeds under extremely mild conditions in aqueous solution at room temperature and can therefore be used for complicated syntheses. The mechanism of this reaction proved to be very complicated and has been elucidated only recently. The ring opening of quaternary salts of trisubstituted isoxazoles by nucleophiles proceeds under similar conditions, and the mechanism of this reaction was extensively studied by Kohler et The authors...

Many studies have been reported on extractability and concentration of protein from leafy plants (13, 14). While it is more efficient to consume the leafy vegetable or fruit directly, considerable quantities of less available protein can be made available through extraction and concentration into LPC. As pointed out by Pirie (13) and Kohler Knuckles (14), an LPC processing plant could be oriented near packinghouses for leafy vegetables so that leaves, stems, and stalks trimmed from these vegetables before being sent to market, could subsequently be extracted for protein. Leaf protein processes are covered in more detail in another chapter. 

Because of their electronic properties, particularly their visible-ultraviolet band gap, tungsten oxides have been the focus of a number of catalysis studies. Kohler and Gopel examined the electrocatalytic properties of W02.72 using spectroscopic surface...

NASICON have been studied (Kohler Schulg, 1985). LISICON type FICs are found to show negative activation volumes at high pressures (Bose et al., 1984).

Precise measurements of the excited state lifetimes of the DNA constituents were not available till very recently, mainly due to the limited time resolution of conventional spectroscopic techniques. Studying the DNA nucleosides by transient absorption spectroscopy, Kohler and co-workers observed a very short-lived induced absorption in the visible which they assigned to the first excited state [5,6]. The lifetimes observed were all well below 1 picosecond. The first femtosecond fluorescence studies of DNA constituents were performed using the fluorescence upconversion technique. Peon and Zewail [7] reported that the excited state lifetimes of DNA/RNA nucleosides and nucleotides all fall in the subpicosecond time, thus corroborating the results obtained by transient absorption. 

B. Kohler 1 would like to ask two questions to Prof. Zewail. First, in your investigation of the electron transfer reaction in a benzene- complex, the sample trajectory calculations you showed appear to suggest that the charge transfer step may induce vibrationally coherent motion in h-. Have you tested this possibility experimentally My second question concerns your intriguing results on a tautomerization reaction in a model base-pair system. In many of the barrierless chemical reactions you have studied, you have been able to show that an initial coherence created in the reactant molecules is often observable in the products. In the case of the 7-azaindole dimer system your measurements indicate that reaction proceeds quite slowly on the time scale of vibrational motions (such as the N—H stretch) that are coupled to the reaction coordinate. What role do you think coherent motion might play in reactions such as this one that have a barrier ...
