  • In United States black mothers have consistently been treated as national outsiders, as women whose children, although ostensibly entitled to full citizenship, are in practice rarely provided with equal protection within the nation′s borders or under its laws. From the time he began writing in the aftermath of the failures of national Reconstruction, the African American public intellectual and political activist W. E. B. Du Bois realized that a truly effective anti-racist politics would also have to contend with the particular ways in which U.S. racism targeted black mothers. In short, he understood that an effective anti-racism would necessarily have to be a form of anti-sexism. This article examines the myriad ways in which Du Bois attempted to reconstruct the relationship between race and reproduction in the interest of producing anti-racist, anti-nationalist, as well as internationalist thinking. In so doing it treats the various representations of black maternity and child birth that Du Bois created, and elaborates on the rhetorical and political function of these representations in combating the racialization of national belonging on the one hand, and in articulating universal black citizenship, or what this article theorizes as racial globality on the other. The article begins by considering Du Bois′s attempts to transcend ideas about the racialized reproductive body as a source of national belonging within the United States, particularly his efforts to contest the idea of the reconstructing nation as a white nation reproduced exclusively by white women. Through analysis of Du Bois′s depiction of the birth and death of his son in his monumental work The Souls of Black Folk (1903) it demonstrates his reluctance to build an anti-racist politics founded on the idea that belonging within the nation is something that can be bestowed by one′s mother. The article proceeds by turning to Du Bois less well-known romantic novel, Dark Princess (1928) in which, by contrast, he depicts the birth of a "golden chi1d" who belongs not only within the United States, but within the world. This child, the son of an African American man and an Indian Princess, is cast as a messenger and messiah of a utopian alliance between pan-Asia and pan-Africa. In exploring the relationship between these two reproductive portraits, the article moves from a discussion of Du Bois′s critique of the ideological construction of the U.S. as a white nation reproduced by white progenitors, to an examination the literary figuration of a b1aek mother out of whose womb a black diasporic anti-imperialist alliance springs. In contrast to previous scholarship, which has tended to focus on the critique of U.S. racial nationalism that Du Bois expressed in his early work, or on the internationalism that he later embraced, this article pays close attention to how Du Bois′s anti-nationalist and internationalist politics together subtended by subtle, but constitutive, sexual politics.

  • Die sogenannten verba pura bilden eine Teilmenge der germanischen starken Verben der VII. KLasse. Sie sind auf einsilbige langvokalisch auslautende Wurzeln des Vorurgermanischen $zur\"{u}ckzufuhren$: z. B. ${\ast}kn\bar{e}an$ 'erkennen', ${\ast}m\bar{e}an$ '$m\"{a}hen$', ${\ast}bl\bar{o}an$ $'bl\"{u}hen'$, ${\ast}m\bar{o}an$ $'qu\"{a}hlen'$. Um den Begriff der verba pura genau zu $erkl\"{a}ren$, stellt man diesen Verben die sogenannten verba impura $gegen\"{u}ber$, bei denen auf die lang Wurzelvokale urgerm. ${\ast}-\bar{e}-$ und ${\ast}-\ber{o}-$ ein Konsonant folgl: z.. B. urgerm. ${\ast}l\bar{e}tan$ (got. \etan) 'lassen', ${\ast}hw\bar{o}pan$ (got. hvopan) 'sich $r\"{u}hmen$'. Die germanischen starken Verben der VII. Klasse hat die $st\"{a}rksten$ Umgestaltungen mitgemacht, und zwar die verba pura noch mehr. In diesem Aufsatz untersuchte ich die $Gr\"{u}nde$ ihrer Umgestaltungen im germanischen Verbalsystem. Danach wird der Vorgang erschlossen, wie die verba pura in Ahd. zu den schwachen Verben I $\"{u}bertraten$. Dabei werden die folgenden Punkte besonders behandelt: Hatten die $fr\"{u}hzeitigen${\;}Pr\"{a}sensformen$ der verba pura -i-, das aus -jan herausgeht? Wenn nein, wie haben die verba pura zur schwachen Flexion $\"{u}bertraten$? Warum konnten die verba pura wie die anderen redupliziernden Verben in Ahd. nicht zu ablautenden Verben $\"{u}bergehen$?

  • One of the research objectives in the area of multimedia human-computer interaction is the application of artificial intelligence and robotics technologies to the development of computer interfaces. This involves utilizing many forms of media, integrating speed input, natural language, graphics, hand pointing gestures, and other methods for interactive dialogues. Although current human-computer communication methods include computer keyboards, mice, and other traditional devices, the two basic ways by which people communicate with each other are voice and gesture. This paper reports on research focusing on the development of an intelligent multimedia interface system modeled based on the manner in which people communicate. This work explores the interaction between humans and computers based only on the processing of speech(Work uttered by the person) and processing of images(hand pointing gestures). The purpose of the interface is to control a pan/tilt camera to point it to a location specified by the user through utterance of words and pointing of the hand, The systems utilizes another stationary camera to capture images of the users hand and a microphone to capture the users words. Upon processing of the images and sounds, the systems responds by pointing the camera. Initially, the interface uses hand pointing to locate the general position which user is referring to and then the interface uses voice command provided by user to fine-the location, and change the zooming of the camera, if requested. The image of the location is captured by the pan/tilt camera and sent to a color TV monitor to be displayed. This type of system has applications in tele-conferencing and other rmote operations, where the system must respond to users command, in a manner similar to how the user would communicate with another person. The advantage of this approach is the elimination of the traditional input devices that the user must utilize in order to control a pan/tillt camera, replacing them with more "natural" means of interaction. A number of experiments were performed to evaluate the interface system with respect to its accuracy, efficiency, reliability, and limitation.

  • This article is intended to study histopathological and immunohistochemical response after autogenous full-thickenss skin graft in rat. 12 male Sprague-Dawley rats were used as the experimental animals. A $1Cm{\times}1Cm$ skin(0.7mm diameter) was taken on the right inguinal area of the rat. Another full-thickeness skin graft($1Cm{\times}1Cm$) was taken from the left inguinal area of the rat. And it was transplanted to the right inguinal area of the rat. The left side wound was closed directly. Light microscopic observation was made at the postoperative $1^{\circ}3^{\circ}8^{\circ}16$ day, after the hematoxylin - Eosin staining of the 4u-thick paraffin embedded specimens and the immunoshitochemical staining of the 10u-thick frozen specimens with mouse anti-rat monoclone antibodies and ABC staining kit. The results were as follows. 1. Electromicroscopic studies revealed interstitial tissue bleeding of transplanted autogenous skin. The response was severe in the 1 day group after operation, moederate in 3 day group, mild in 8 day group, and almost resovled in the 16 days group. 2. Electromicrospic studied also revealed a mild monocyte response in the 3 day and 8 day group. A histiocytic infiltrate was observed. There was a mild response in the 3 day group and moderate response in the 8 day group. 3. Immunohistochmically studies revealed a few pan T cells in the 1 day group, mild appearance of pen T cells and cytotoxic T cells in the 3 day group, a moderate infiltrate of pan T cells and helper T cells in the 8 day group, and total resolution of pan T cells in the 16 day group. 4. According to these finding, a strong inflammatory response was observed around transplanted autogenous skin in the 3 & 8 day groups. In the 16 day group this response had resolved histopathologically and immunohistologically.

  • Objectives: This study evaluated the microtensile bond strength (${\mu}TBS$) of polymer-ceramic and indirect composite resin with 3 classes of resin cements. Materials and Methods: Two computer-aided design/computer-aided manufacturing (CAD/CAM)-fabricated polymer-ceramics (Enamic [ENA; Vita] and Lava Ultimate [LAV; 3M ESPE]) and a laboratory indirect composite resin (Gradia [GRA; GC Corp.]) were equally divided into 6 groups (n = 18) with 3 classes of resin cements: Variolink N (VAR; Vivadent), RelyX U200 (RXU; 3M ESPE), and Panavia F2 (PAN; Kuraray). The ${\mu}TBS$ values were compared between groups by 2-way analysis of variance and the post hoc Tamhane test (${\alpha}=0.05$). Results: Restorative materials and resin cements significantly influenced ${\mu}TBS$ (p < 0.05). In the GRA group, the highest ${\mu}TBS$ was found with RXU ($27.40{\pm}5.39N$) and the lowest with VAR ($13.54{\pm}6.04N$) (p < 0.05). Similar trends were observed in the ENA group. In the LAV group, the highest ${\mu}TBS$ was observed with VAR ($27.45{\pm}5.84N$) and the lowest with PAN ($10.67{\pm}4.37N$) (p < 0.05). PAN had comparable results to those of ENA and GRA, whereas the ${\mu}TBS$ values were significantly lower with LAV (p = 0.001). The highest bond strength of RXU was found with GRA ($27.40{\pm}5.39N$, p = 0.001). PAN showed the lowest ${\mu}TBS$ with LAV ($10.67{\pm}4.37N$; p < 0.001). Conclusions: When applied according to the manufacturers' recommendations, the ${\mu}TBS$ of polymer-ceramic CAD/CAM materials and indirect composites is influenced by the luting cements.
