Engaging Ancient Islamic Traditions in the Poetry of Saleha Ghabesh
This paper explores the integration of ancient Islamic heritage in Emirati literature, particularly the history of the rise and fall of the Muslim Empire in Andalusia, in an attempt to confront regional challenges and international transformations in the current era. Navigating the intersection between heritage and identity, the Emirati poet, Saleha Ghabesh, attempts to incorporate the ancient Islamic heritage in Andalusia as a dynamics of liberation in order to articulate domestic issues integral to the geopolitics of the United Arab Emirates and the Arab region in the age of globalization. Transforming the mythic history of Andalusia into a narrative of disclosure, the poet encounters a web of traditions and policies responsible for significant ramifications in the UAE and the Arab world. In a related context, the paper points out that the technique of adaptation, used by Ghabesh, which includes recollection rephrasing and re-writing of ancient heritage and Andalusian legacies to fulfill contemporary purposes, is part of the issue of hybridity and interculturation, characterizing the contemporary experience of political and cultural globalization. By assimilating heritage and historical traditions into contemporary Emirati literature, Ghabesh aims to link the past with the present reconstructing ancient narratives which shaped the cultural mythology of the Arab people
Toward a hybrid poetics: the integration of western/Christian narratives in modern Arabic poetry
The paper explores the attempt of Muslim Arab poets to integrate symbols, myths and narratives, appropriated from western/Christian traditions to create a hybrid poetics able to confront the challenges of the post WWII era. The paper argues that in spite of the great history of Arabic poetry, deeply rooted in Islamic heritage, Muslim Arab poets have been engaged in an inter-civilizational dialogue with western masters and texts incorporating motifs and discourses derived from traditions different from the Arab cultural context. Adapting western forms and strategies to fit local political purposes, Arab poets developed a poetics of opposition to undermine the foundations of a stagnant world and a backward culture. Combining western and eastern traditions, Arab poets in the post WWII era, developed an indigenous poetic dynamics to confront political hegemony and challenge local tyrannical regimes, the heirs of the colonial legacy
The dialectics of homeland and identity: Reconstructing Africa in the poetry of Langston Hughes and Mohamed Al-Fayturi
The article investigates the dialectics between homeland and identity in the poetry of the Sudanese poet, Mohamed Al-Fayturi and his literary master, Langston Hughes in order to underline their attitudes toward crucial issues integral to the African and African-American experience such as identity, racism, enslavement and colonisation. The article argues that – in Hughes’s early poetry –Africa is depicted as the land of ancient civilisations in order to strengthen African-American feelings of ethnic pride during the Harlem Renaissance. This idealistic image of a pre-slavery, a pre-colonial Africa, argues the paper, disappears from the poetry of Hughes, after the Harlem Renaissance, to be replaced with a more realistic image of Africa under colonisation. The article also demonstrates that unlike Hughes, who attempts to romanticize Africa, Al-Fayturi rejects a romantic confrontation with the roots. Interrogating western colonial narratives about Africa, Al-Fayturi reconstructs pre-colonial African history in order to reveal the tragic consequences of colonisation and slavery upon the psyche of the African people. The article also points out that in their attempts to confront the oppressive powers which aim to erase the identity of their peoples, Hughes and Al-Fayturi explore areas of overlap drama between the turbulent experience of African-Americans and the catastrophic history of black Africans dismantling colonial narratives and erecting their own cultural mythology
Virtual Rendering based Second Life Mobile Application to Control Ambient Media Services
In this paper we propose the development details of a mobile client that allows virtual 3D avatar interaction and virtual 3D annotation control in Second Life. We established adaptation based virtual rendering of the Second Life client and encoded the real-time frames into video stream, which is suitable for mobile client rendering. Additionally, we re-mapped the touch-based interaction of the user and feed that to the Second Life client in a form of keyboard and mouse interactions. As a proof of concept, we annotated a virtual environment object in Second Life and linked that with a media service by UPnP [5]. Further, we captured the mobile interaction of the user and provided controller interface to change states of the media object through the virtual object interaction. We argue that by using the mobile Second Life virtual interface the user has a better look to monitor and control the home appliances. We present illustration of the prototype system and show its application in a smart environment setup

Maternal hypoxia decreases capillary supply and increases metabolic inefficiency leading to divergence in myocardial oxygen supply and demand
Maternal hypoxia is associated with a decrease in left ventricular capillary density while cardiac performance is preserved, implying a mismatch between metabolism and diffusive exchange. We hypothesised this requires a switch in substrate metabolism to maximise efficiency of ATP production from limited oxygen availability. Rat pups from pregnant females exposed to hypoxia (FIO2=0.12) at days 10-20 of pregnancy were grown to adulthood and working hearts perfused ex vivo. 14 C-labelled glucose and 3 H-palmitate were provided as substrates and metabolism quantified from recovery of 14CO2 and 3 H2O, respectively. Hearts of male offspring subjected to Maternal Hypoxia showed a 20% decrease in cardiac output (P<0.05), despite recording a 2-fold increase in glucose oxidation (P<0.01) and 2.5-fold increase (P<0.01) in palmitate oxidation. Addition of insulin to Maternal Hypoxic hearts, further increased glucose oxidation (P<0.01) and suppressed palmitate oxidation (P<0.05), suggesting preservation in insulin signalling in the heart. In vitro enzyme activity measurements showed that Maternal Hypoxia increased both total and the active component of cardiac pyruvate dehydrogenase (both P<0.01), although pyruvate dehydrogenase sensitivity to insulin was lost (NS), while citrate synthase activity declined by 30% (P<0.001) and acetyl-CoA carboxylase activity was unchanged by Maternal Hypoxia, indicating realignment of the metabolic machinery to optimise oxygen utilisation. Capillary density was quantified and oxygen diffusion characteristics examined, with calculated capillary domain area increased by 30% (P<0.001). Calculated metabolic efficiency decreased 4-fold (P<0.01) for Maternal Hypoxia hearts. Paradoxically, the decline in citrate synthase activity and increased metabolism suggest that the scope of individual mitochondria had declined, rendering the myocardium potentially more sensitive to metabolic stress. However, decreasing citrate synthase may be essential to preserve local PO2, minimising regions of hypoxia and hence maximising the area of myocardium able to preserve cardiac output following maternal hypoxia
High density of peritumoral lymphatic vessels is a potential prognostic marker of endometrial carcinoma: a clinical immunohistochemical method study
<p>Abstract</p> <p>Background</p> <p>The lymphatic system is a major route for cancer cell dissemination and also a potential target for antitumor therapy. To investigate whether increased lymphatic vessel density (LVD) is a prognostic factor for nodal metastasis and survival, we studied peritumoral LVD (P-LVD) and intratumoral LVD (I-LVD) in samples from 102 patients with endometrial carcinoma;</p> <p>Methods</p> <p>Endometrial carcinoma tissues were analyzed for lymphatic vessels by immunohistochemical staining with an antibody against LYVE-1. Univariate analysis was performed with Kaplan-Meier life-table curves to estimate survival, and was compared using the log rank test. Prognostic models used multivariate Cox regression analysis for multivariate analyses of survival;</p> <p>Results</p> <p>Our study showed that P-LVD, but not I-LVD, was significantly correlated with lymph vascular space invasion (LVSI), lymph node metastasis, tumor stage, and CD44 expression in endometrial carcinoma. Moreover, P-LVD was an independent prognostic factor for progression-free survival and overall survival of endometrial carcinoma;</p> <p>Conclusions</p> <p>P-LVD may serve as a prognostic factor for endometrial carcinoma. The peritumoral lymphatics might play an important role in lymphatic vessel metastasis.</p
