Introduction. The article is devoted to the analysis of a unique cross-encolpion of the WesternEuropean type from the excavations of the Mangup Prince’s Palace. Methods. The research is complex. When describing the find, traditional methods of art history analysis were used, and data from X-ray fluorescence studies were used to determine the material of the product. Attribution of the cross is made on the basis of the generally accepted method of analogies in archaeological science. Analysis. The encolpion is related to a small group of cast silver crosses with “Latin” features, which were produced during the third quarter of the 15th century in one of the craft workshops of Kaffa. Their author was a master-scholarship holder who most likely moved to the capital of Genoese Gazaria in the Northern Black Sea region from one of the cities of Northern Italy. Results. Among the many reasons why this encolpion, as a mandatory attribute of the clothing of a Catholic Priest, could end up on Mangup, the most likely are: unknown in the sources Genoese embassy to the capital of the Principality of Feodoro in the period of 1450–1475 for the purpose of establishing a permanent Catholic mission here; the presence of a Catholic priest in the large embassies of Kaffa to the court of the rulers of Feodoro in 1455, 1465 or around 1471; participation of Genoese, who fled from Kaffa after its capture by the Ottoman army, in the subsequent defense of the Mangup fortress in summer and autumn 1475.

Rate Of Accumulation

In addition to its established oncological indications the sensitivity of bone scintigraphy is of steadily increasing significance in traumatology. Inactivity- induced osteoporosis plays a major role during the immobilization period in the plaster cast. In the region of the joints remodelling intensity may reach such a high level that the non-injured bone shows a higher rate of accumulation than the fracture. This process already begins between the third and fourth week of immobilization. The highest uptake is found after fracture of the scaphoid bone at the end of twelve weeks of immobilization. Control scintigraphies at intervals of several days are indicated to differentiate between various clinical conditions (pseudoarthrosis, activated osteoarthrosis, algodystrophy in case of doubtful x-ray results).

The chapter focuses on how leadership was taught in the distant and recent past. The first section is on five of the greatest leadership teachers ever—Lao-tzu, Confucius, Plato, Plutarch, and Machiavelli—who shared a deep belief in the idea that leadership could be taught and left legacies that included timeless and transcendent literary masterworks. The second section explores how leadership went from being conceived of as a practice reserved only for a select few to one that could be exercised by the many. The ideas of the Enlightenment changed our conception of leadership. Since then, the leadership literature has urged people without power and authority, that is, followers, to understand that they too could be agents of change. The third section turns to leadership and management in business. It was precisely the twentieth-century failure of business schools to make management a profession that gave rise to the twenty-first-century leadership industry.

This book addresses the sounds of the Crimean War, along with the many ways nineteenth-century wartime is aurally constructed. It examines wide-ranging experiences of listeners in Britain, France, Turkey, Russia, Italy, Poland, Latvia, Daghestan, Chechnya, and Crimea, illustrating the close interplay between nineteenth-century geographies of empire and the modes by which wartime sound was archived and heard. This book covers topics including music in and around war zones, the mediation of wartime sound, the relationship between sound and violence, and the historiography of listening. Individual chapters concern sound in Leo Tolstoy’s wartime writings, and his place within cosmopolitan sensibilities; the role of the telegraph in constructing sonic imaginations in London and the Black Sea region; the absence of archives for the sounds of particular ethnic groups, and how songs preserve memories for both Crimean Tatars and Polish nationalists; the ways in which perceptions of voice rearranged the mental geographies of Baltic Russia, and undermined aspirations to national unity in Italy; Italian opera as a means of conditioning elite perceptions of Crimean battlefields; and historical frames through which to understand the diffusion of violent sounds amid everyday life. The volume engages the academic fields of musicology, ethnomusicology, history, literary studies, sound studies, and the history of the senses.

Abstract Background This study was done to observe the incidence of Osteo-line on the femur neck and to explore the clinical application of Osteo-line in osteotomy. Methods Eighty-nine adult femur specimens were selected to observe the incidence of Osteo-line on the femur neck. From August 2015 to January 2019, a total of 278 patients who completed unilateral hip arthroplasty at the Third Hospital of Hebei Medical University were retrospectively included. Patients who accepted osteotomy via Osteo-line on the femur neck were defined as the experimental group (n = 139), and patients who accepted osteotomy via traditional method (The femoral distance 1.5 cm above the trochanter was retained for osteotomy by visual inspection.) were defined as the control group (n = 139). According to the postoperative pelvic X-ray, Photoshop was used to evaluate the leg length discrepancy (LLD) by the CFR-T-LT method. Results Among the 89 specimens, the incidence of anterior Osteo-line was 75.28%, and the incidence of posterior Osteo-line was 100%. According to the clinical application results, the incidence of anterior Osteo-line on the femur neck was 80%, and the incidence of posterior Osteo-line was 100%. The Osteo-line was clearer than those on the femoral specimens. Twenty-six cases had LLD greater than 1 cm (9.29%), including 2 cases in the experimental group and 24 cases in the control group. The average postoperative LLD in the experimental group (0.19 ± 0.38 mm) was significantly shorter than in the control group (0.54 ± 0.51 mm)(P = 0.005). Conclusion The incidence of Osteo-line on the femur neck was high, and patients who accepted osteotomy via Osteo-line on the femur neck can achieve shorter postoperative LLD than the control group.

As If

My paper analyses the 15th-century seven-sacraments font at the medieval church of St Peter and St Paul at Salle in Norfolk (England). The church guides and gazetteers that describe the font, and the church in which it is situated, owe both their style and content to Art History, focusing as they do on their material and aesthetic dimensions. The guides also tend towards isolating the various elements of the font, and these in turn from the rest of the architectural elements, fittings and furniture of the church, as if they could be meaningfully experienced or interpreted as discrete entities, in isolation from one another. While none of the font descriptions can be faulted for being inaccurate, they can, as a result of these tendencies, be held insufficient, and not quite to the purpose. My analysis of the font, by means of Heidegger’s concept of Dwelling, does not separate the font either from the rest of the church, nor from other fonts, but acknowledges that it comes to be, and be seen as, what it is only when considered as standing in ‘myriad referential relations’ to other things, as well as to ourselves. This perspective has enabled me to draw out what it is about the font at Salle that can be experienced as not merely beautiful or interesting, but also as meaningful to those—believers and non-believers alike—who encounter it. By reconsidering the proper mode of perceiving and engaging with the font, we may spare it from being commodified, from becoming a unit in the standing reserve of cultural heritage, and in so doing, we, too, may be momentarily freed from our false identities as units of production and agents of consumption. The medieval fonts and churches of Norfolk are, I argue, not valuable as a result of their putative antiquarian qualities, but invaluable in their extending to us a possibility of dwelling—as mortals—on the earth—under the sky—before the divinities.

AbstractFrom three VLBA observations at 5 GHz, spanning 13 months, we have measured the trigonometric parallax of Sco X-1 of 0.23 ± 0.28 mas; hence its distance is > 1300 pc. This supports the hypothesis that the the x-ray luminosity is near the Eddington Limit.All three VLBA observations show a radio core of flux density 0.5 mJy and size < 4 mas. However, the third VLBA observation revealed two additional radio components, separated by 12 mas (≈ 20 au) on opposite sides of the radio core. The evolution of these new components is unknown until additional observations can be made. The relative luminosity and separation of the two radio components are inconsistent with the Doppler beaming of two identical ejecta from the radio core.

Diffraction-contrast TEM, focused probe electron diffraction, and high-resolution X-ray diffraction were used to characterize the dislocation arrangements in a 16µm thick coalesced GaN film grown by MOVPE LEO. As is commonly observed, the threading dislocations that are duplicated from the template above the window bend toward (0001). At the coalescence plane they bend back to lie along [0001] and thread to the surface. In addition, three other sets of dislocations were observed. The first set consists of a wall of parallel dislocations lying in the coalescence plane and nearly parallel to the substrate, with Burgers vector (b) in the (0001) plane. The second set is comprised of rectangular loops with b = 1/3 [110] (perpendicular to the coalescence boundary) which originate in the coalescence boundary and extend laterally into the film on the (100). The third set of dislocations threads laterally through the film along the [100] bar axis with 1/3<110>-type Burgers vectors These sets result in a dislocation density of ∼109 cm−2. High resolution X-ray reciprocal space maps indicate wing tilt of ∼0.5º.

Die Bonding

We report on the die bonding processes and how the surface roughness and metallization schemes affect the processes of die bonding in 4H-SiC device fabrication using a soldering test and die shear test (DST) with differently prepared 4H-SiC samples. The first set of samples (FZ#1 and FZ#2) was capped with sequentially evaporated Ti and Au on an annealed Ni layer. The second set of samples (FZ#3 and FZ#4) and the third set of samples (FZ#5 and FZ#6) were prepared by 4μm-thick Au electroplating on an annealed Ni layer and an un-annealed Ni layer, respectively. The quality of the soldering, such as the solder coverage, void, and adhesion, was characterized by optical microscope, X-ray microprobe, and DST. We found that the samples (FZ#4 and FZ#6) deposited by Au electroplating on C-face (bottom-side) 4H-SiC provided a satisfactory result for the tests of solder coverage, void, and DST and also realized the cleaning process prior to the electroplating and soldering was the most crucial in the die packaging processes of vertical structure devices. The void fraction measured by X-ray microprobe for the samples, FZ#4 and FZ#6 was 2.2% (average for 5 samples) and 0.8% (average for 3 samples), respectively.
