Chemical and biological characterization of paper: A case study using a proposed methodological approach

The maskilic characterization of the nineteenth century as a period of decline and ossification for Hasidism is increasingly eschewed by scholars, yet continues to mark current research in significant ways. As a case study, this article takes up Rabbi Shmuel Schneersohn of Lubavitch (“Maharash,” 1834–1882), rescrutinizing (1) the controversy surrounding the onset of his leadership, (2) his personality and charisma, (3) his methodological approach to the teachings and texts that he inherited from his predecessors, and (4) his theological contributions and their place in the broader trajectory of Chabad's intellectual history. His tenure emerges as a false twilight, in which a new foundation was laid for the perpetuation and expansion of Chabad-Lubavitch, as both an intellectual and activist movement, in the century that followed.

Abstract The understanding of the ecological behavior of Arbutus unedo L. in the context of its valuation is the objective assigned to this work. Two different observation sites were selected in Tamalous forest (Skikda) presenting different habitat contexts along a north-south transect. The methodological approach adopted is that of the comparative analysis of the physico-chemical and biological characteristics between a soil under cover of Arbutus unedo L. and bare control soil. The results obtained highlighted quite significant differences between the soils covered with strawberry tree, show that they are acidic in nature, an increase in the rate of organic matter, of the CEC which increases significantly as well as the concentration of exchangeable cations. As for the soil fauna, we observe a clear increase in biomass than in density at the level of all families of individuals, in particular the stations under the strawberry tree cover.

Deformation Patterns

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
