Abstract This article reconstructs and compares photographic perspectives on the historical phenomenon of preparing German-Jewish youth for emigration from Germany, and their subsequent training in Palestinian kibbutzim in the framework of the hachshara and the youth aliyah. It considers the photographers’ status, differentiating between professional photography and the work of amateurs, and investigates the use and addressees of these images. The image analysis that underlies this study examines facets of the photographic and pictorial conception of chalutzian youth, including motifs, style, and atmospheres. In the process, photography is classified as a unique historical image source, in which the conditions of the time inscribe themselves even beyond personal and political intentions, interests, and contexts of usage. The image analysis also aims to reconstruct the specific, visually represented individual and collective experiences of the producers and addressees of photographic images in Germany and Mandatory Palestine.

ABSTRACT Introduction: Debris buildup on the bracket-wire interface can influence friction. Cleansing brackets with air-powder polishing can affect this process. Objective: The aim of this study was to evaluate the frictional force and amount of debris remaining on orthodontic brackets subjected to prophylaxis with air-powder polishing. Methods: Frictional force and debris buildup on the surface of 28 premolar brackets were evaluated after orthodontic treatment. In one hemiarch, each bracket was subjected to air-powder polishing (n = 14) for five seconds, while the contralateral hemiarch (n = 14) served as control. Mechanical friction tests were performed and images of the polished bracket surfaces and control surfaces were examined. Wilcoxon test was applied for comparative analysis between hemiarches at p < 0.05. Results: Brackets that had been cleaned with air-powder polishing showed lower friction (median = 1.27 N) when compared to the control surfaces (median = 4.52 N) (p < 0.01). Image analysis showed that the control group exhibited greater debris buildup (median = 2.0) compared with the group that received prophylaxis with air-powder polishing (median = 0.5) (p < 0.05). Conclusion: Cleansing orthodontic brackets with air-powder polishing significantly reduces debris buildup on the bracket surface while decreasing friction levels observed during sliding mechanics.

Successful utilization of an automated optical scanning system for the purpose of assessing the trash factor included in the grade classification of cotton was demonstrated in a study that featured analysis of cottons representing a broad range of trash levels and lint colors. The utility of image analysis as an absolute indication of grade-related differences in cotton was statistically confirmed. Sources contributing to the variability of nonlint assessment by optical imaging were defined and analyzed, as was the influence of interrelated grade factors such as lint coloration on optically measured contaminant levels. In a direct comparison with the Shirley Analyzer, computerized optical scanning was shown to be at least as reliable as this standard method for determining nonlint waste.

Photographic images of the Samseong-version (三省本: Korea’s Treasure No. 758-1) and the Gongin-version (空印本: Korea’s Treasure No. 758-2) of Nammyeongcheon Hwasangsong Jeungdoga (南明泉和尙頌證道歌: Nanmingquan Song Zhengdaoge) were compared and analyzed to investigate the differences between the two versions. According to a report in 2012 at the time of the designation of the Gongin-version as Korea’s treasure, both versions were printed from the same woodblocks. The Gongin-version is presumed to be a later print than the Samseong-version. The two versions are very similar in format and shape of border lines and characters. It is difficult to determine the differences with the naked eye, even for experts. In this study, based on the printing characteristics observed from each version through image analysis, useful evidence to determine whether it was printed using the same or different woodblocks and the order of printing was collected. As a result of careful image comparison and analysis, we concluded that the Samseong- and the Gongin-version were printed from different woodblocks, or possibly different typesetting. It was difficult to agree with the content of the report that the Gongin-version was a later print than the Samseong-version. In addition, it was noted that the Gongin-version print has characteristics quite different from the typical characteristics of woodblock printing seen in the Samseong-version. Additional investigations and follow-up studies on the printing technology used for Gongin-version print and the timing of printing are recommended.

The first goal of the work described below was to investigate and establish means for producing ultra high quality photographic images for automated image analysis. This procedure was absolutely mandatory because no reliable quantitative automated image analysis can be done with images which are deficient in any one of a number of essential properties. The second goal was to achieve a high degree of reproducibility in preparing the image. In order to achieve these goals we set out to optimize our image characteristics heuristically.We have found that high contrast is the most important factor in attaining superior image quality in electron micrographs of carbon blacks. The individual factors which affect image contrast in electron micrographs have been discussed in the literature.

Abstract This article deals with Shakespeare’s reception among German Jewish youth in the early twentieth century. The Jewish youth movements played an appreciable role in Jewish education and culture. The various Jewish youth movements reflected the German Jewish society of the time. Despite the influence of the German youth movement, the young people developed their own German Jewish Bildung canon. Many young Jews in Germany perceived Bildung as an ideal tool for full assimilation. Bildung placed an emphasis on the Jewish youth as an individual, and so served as an ideal tool for full assimilation. My thesis is that by means of the youth movement, German Jewish youth could develop new interpretations of identity, through the creation of a European Bildung ideal, which includes an awareness of the significance of Shakespeare.

Abstract One of common methods of determining landscape change usually is to compare maps and photographic images of the same places in different time horizons. Landscape painting, which has a long and rich tradition in the Czech Republic, can be used similarly. Landscape-ecological interpretation of selected works by painters of the 19th century - Julius Mařák, František Kaván and Antonín Slavíček was done in this paper. Some pictures of the Českomoravská vrchovina (Bohemian-Moravian highlands) by Josef Jambor from the mid-20th century were used for detailed comparative analysis to the level of habitats. We compared 80 landscape paintings and found that most of the painted sceneries have changed for worse.

In this paper, I offer a comparative analysis of the political thoughts of twentieth century Iranian revolutionary thinker and sociologist Ali Shari’ati (1933–1977) and German-Jewish philosopher Walter Benjamin (1892–1940). Despite their conspicuously independent historical-theoretical trajectories, both Shari’ati and Benjamin engaged with theology and Marxism to create theological–political conceptions of the revolution of the oppressed. Shari’ati re-interpreted and re-animated Shia history from the angle of contemporary concerns to theorize a revolution against all forms of domination. In comparison, Benjamin fused Marxism with Jewish theology in his call to seize the possibilities of past failed revolutions in the present. Both Shari’ati and Benjamin conceptualized an active messianism led by each generation, eliminating the wait for the return of a messiah. As a result, each present moment takes on a messianic potential; the present plays an essential role to both thinkers. Past was also essential to both, because theology (through remembrance) had made the past sufferings incomplete to them. Both thinkers viewed past sufferings as an integral part of present struggles for justice in the form of remembrance (or yād or zekr for Shari’ati, and Zekher for Benjamin). I explore the ways Shari’ati and Benjamin theorized the role of the past in the present, remembrance, and messianism to create a dialectical relation between theology and Marxism to reciprocally transform and compliment both of them.
