Heidegger and Marcuse: The Catastrophe and Redemption of History
This brief booklet contrasts the philosophies of know-how of Heidegger and Marcuse, one among Heidegger's celebrity scholars, and relates their paintings to modern expertise experiences. Feenberg units out the ancient and theoretical historical past of the controversy, then discusses every one philosopher's concept in flip, and ends with a tremendous research of the results for modern expertise reports.
Die physikalischen und chemischen Grundlagen der Glasfabrikation
Die Wissenschaft yom Glase ist infolge der Anwendung neuer physi kalischer Auffassungen und Methoden derart in Breite und Tiefe an geschwollen, daB es dem Ingenieur und dem Studenten immer schwie riger wird, die wissenschaftlichen Fundamente zu iibersehen. Es ist Zweck dieses Buches, den Zusammenhang zwischen der Grundlagen forschung einerseits und der Glaschemie und der Technologie anderer seits wieder herzustellen.
A dialogue of categorising the ideational context and emotional adventure that could happen in a psychoanalytic interview. The textual content goals to extend the reader's realizing of cognition and its scientific ramifications.

Unfortunately, this was only detected after publication by HPLC analysis of the corresponding di-(-)-camphanates. Nevertheless, there is fortunately no need to revise our conclusions concerning the absolute con figuration of natural actinioerythrin. Due to partial racemization, the compounds 112, 113, 116, 103, 117 and 118 could not be obtained optically pure so far. CONCLUDING REMARKS The foregoing discussion has shown that the search for a technical synthesis of astaxanthin has led to numerous investigations in the field of 3,4-oxygenated xanthophylls.
The CD spectra of 20 and 3'-O-didehydrolutein, obtained by Oppenauer oxidation of (3R,3'R, 6'R)-lutein, clearly show strong opposite Cotton effects at 276 and 270 nm, respectively (Fig. 11). Fritschiellaxanthin A new carotenoid, called fritschiellaxanthin, with an interesting combination of the astaxanthin and lutein é--end groups, has recently been isolated and fully characterized from the green alga Fritschiella tuberosa (Ref. lo). With the necessary building units at hand, we have tried to synthesize this carotenoid according to the scheme C^_ + C, = C (Fiq.
