The structural unit of solid state collagen complexes has been reported by Porter and Vanamee via EM and by Cowan, North and Randall via x-ray diffraction to be an ellipsoidal unit of 210-270 A. length by 50-100 A. diameter. It subsequently was independently demonstrated by us in dog tendon, dermis, and induced complexes. Its detailed morphologic, dimensional and molecular weight (MW) aspects have now been determined. It is pear-shaped in long profile with m diameters of 57 and 108 A. and m length of 263 A. (Fig. 1, tendon, KMnO4 fixation, Na-tungstate; Fig. 2a, schematic of unit in long, C, and x-sectional profiles of its thin, xB, and bulbous, xA portions; Fig. 2b, tendon essentially unmodified by ether and 0.4 N NaOH treatment, Na-tungstate). The unit consists of a uniquely coild cable, c, of ṁ 22.9 A. diameter and length of 2580-3316 A. The cable consists of three 2nd-strands, s, each of m 10.6 A.

Without help from the west, the small East German opposition,such as it was, never would have achieved as much as it did. Themoney, moral support, media attention, and protection provided bywestern supporters may have made as much of a difference to theopposition as West German financial support made to the East Germanstate. Yet this help was often resented and rarely acknowledgedby eastern activists. Between 1988 and 1990, I worked withArche, an environmental network created in 1988 by East Germandissidents. During that time, the assistance provided by West Germans,émigré East Germans, and foreigners met with a level of distrustthat cannot entirely be blamed on secret police intrigue.Outsiders who tried to help faced a barrage of allegations and criticismof their work and motives. Dissidents who elected to remain inEast Germany distrusted those who emigrated, and vice versa,reflecting an unfortunate tendency, even among dissidents, to internalizeelements of East German propaganda. Yet neither the helpand support the East German opposition received from outside northe mentalities that stood in its way have been much discussed. Thisessay offers a description and analysis of the relationship betweenthe opposition and its outside supporters, based largely on one person’sfirst-hand experience.

Abstract Chitosan is an amorphous translucent substance with a structural unit similar to the polysaccharide structure of the extracellular matrix, It has good antibacterial, biocompatible, and degradable properties. It has important application value in leather, water treatment, medicine, food and other fields, so chitosan and its modified products have received widespread attention. This article reviewed the preparation methods of chitosan-based antibacterial composites in recent years, including chitosan/collagen, chitosan/graphene, chitosan/tannic acid, and chitosan/polyethylene glycol composite materials, elaborates their modification methods and antibacterial mechanism were reviewed in detail, and its applications in the leather industry as antibacterial auxiliaries and water treatment antibacterial adsorption materials were discussed. Finally, the future development and challenges of chitosan-based composite materials in the leather industry were forecasted. Graphical abstract

ABSTRACTGeometric criteria for low interface energy and interface structure were tested for the cubic-rhombohedral system YAG/alumina. Orientation relationships near (111){110}a // (112){110}y and facets on (111)a(112)y were observed in both sol-gel derived composites and directionally solidified eutectic composites. The ΣYAG=12 near-CSL of 2{111}, {110}, {112} was inferred to be the preferred structural unit. Dislocations with b=1/3{111}a and b=1/2{110}a were observed and inferred to accomodate deviation from the structural unit, respectively. The {110}a,y direction met some of the criteria for an invariant line. Although the OR was explained by geometric criteria it would have been difficult to predict it with such criteria
