MARCAS JUDAICAS EM “COMO VIEMOS PARAR A AMAZÔNIA” DE SULTANA LEVY ROSENBLATT
No full textA pesquisa em questão faz parte do projeto de pesquisa Ecos sefarditas: judeus na Amazônia, desenvolvido no campus de Bragança. A investigação tem como escopo fazer uma análise dos aspectos de judeidade presentes nas obras da autora amazônida Sultana Levy Rosenblatt, cuja origem é judaico-sefardista. Para fazer essa sondagem, teremos como principal metodologia a pesquisa bibliográfica referente à presença de judeus sefarditas em território amazônico. Para tanto, autores como Samuel Bechimol, Reginaldo Heller, entre outros, nos fornecerão embasamento teórico histórico. Também será feita a análise de alguns escritos literários da escritora Sultana Levy Rosenblatt. Neste propósito, selecionou-se um texto da referida autora, a saber: “Como viemos parar a Amazônia”. Fez-se também um intertexto com o ensaio “Reminiscências de uma judia marroquina” de Clara Koshen. Em tais escritos, respectivamente, é possível encontrar a presença da cultura judaica de forma veemente. No primeiro, identificamos o processo de imigração de um jovem judeu, vindo da região de Marrocos, para uma comunidade desconhecida, com condições precárias, comparando-se às grandes cidades. A autora narra as aventuras desse jovem, bisavô de Sultana, o qual buscava encontrar prosperidade em terras amazônicas. Na segunda obra, destaca-se a presença das tradições judaicas, as quais são marcadamente descritas, pela autora, como uma forma de preservar a cultura de origem. Diante do exposto é possível inferir que a escritora busca rememorar traços da cultura judaica em terras amazônicas.

ABSTRACT: The research in question is part of the Sephardic Ecos research project: Jews in the Amazon, developed on the campus of Bragança. The investigation has as scope to make an analysis of the aspects of Jewishness present in the works of the Amazonian author Sultana Levy Rosenblatt, whose origin is Jewish-Sephardic. To do this survey, we will have as main methodology the bibliographic research concerning the presence of Sephardic Jews in Amazonian territory. For such, authors such as Samuel Bechimol, Reginaldo Heller, among others, will provide us with historical theoretical background. Also will be made the analysis of some literary writings of the writer Sultana Levy Rosenblatt. In this purpose, a text of the author was selected, namely: "How we came to stop the Amazon". An intertext was also made with the essay "Reminiscences of a Moroccan Jew" by Clara Koshen. In such writings, respectively, it is possible to find the presence of Jewish culture vehemently. In the first, we identified the process of immigration of a young Jewish man from the region of Morocco into an unknown community with precarious conditions compared to the large cities. The author narrates the adventures of this young man, great-grandfather of Sultana, who sought to find prosperity in Amazonian lands. The second work highlights the presence of Jewish traditions, which are markedly described by the author as a way of preserving the culture of origin. In view of the above, it is possible to infer that the writer seeks to recall traces of the Jewish culture in Amazonian lands.

LIGHT, THE RIGHT WAY
No full textRapid urbanization in Dhaka has driven a surge in high-rise office buildings with fully glazed façades, reflecting a global architectural trend favoring transparency and daylight maximization. However, in Dhaka’s hot and humid tropical climate, extensive use of glass façades creates challenges such as visual discomfort, glare, and excessive brightness, which compromise occupant comfort and energy efficiency. This thesis investigates the impact of fully glazed office façades on daylight quality and visual comfort in Dhaka, focusing on daylight contrast and glare issues influenced by building orientation and climatic factors. Through a case study approach combining daylight simulation and on-site occupant surveys, the research evaluates current façade performance. In response, the thesis proposes optimized external shading solutions aimed at balancing daylight penetration with glare reduction to improve visual comfort and occupant well-being. Findings suggest that, without proper shading design, fully glazed façades may not deliver the expected sustainable benefits in Dhaka’s context. Proposed façade shading modifications demonstrate significant improvements in reducing these issues while maintaining natural light penetration. This study highlights the importance of context-sensitive façade design in tropical climates to enhance both energy efficiency and indoor environmental quality
On the Bayesian estimator of interaction models with measurement error and misclassification in covariates
No full textMeasurement error and misclassification in covariates are commonly arising problems
in statistical models. They have negative impacts on statistical inference about the
outcome, including bias and large variability in estimators. Furthermore, in a statistical
model, two or more covariates can interact, which in practice is quite challenging
to deal with. One of the recent techniques is Bayesian method that incorporates the
prior knowledge about parameters. In this research, Bayesian techniques are applied to
the models with interaction terms, while addressing measurement error and misclassification.
Moreover, through extensive simulation studies, Markov Chain Monte Carlo
algorithms are used to implement the Bayesian methods.Includes bibliographical references (pages 82-84)
Technology Development and Characterization of AIInN/GaN HEMTs for High Power Application
No full textAlInN has attracted much attention only recently as a material due to its unique and superior material properties, which is however known to be difficult to be grown among the III-nitride ternary compounds. The electrons confined at the heterointerface of coherently grown AlInN on GaN buffer layers determine crucial electronic properties. This dissertation has been designed targeting the lattice matched AlInN/GaN investigation with very detail to optimize the design, fabrication process, and electronic properties to realize AlInN/GaN HEMTs. Each single step of this process was optimized in order to improve device performance.
The work started with establishing the main features of AlInN/GaN heterostructure in a HEMT configuration through optimizing the device fabrication and investigation of the DC characteristics of planar HEMTs. The study included heterostructures with variable barrier thicknesses along with barrier cap layer. A series of experiments were conducted to analyze the impact of barrier thickness on breakdown and threshold-voltage by fabricating devices with different gate to drain separation and incorporating field plated gate design. In addition, a series of experiments were conducted on barrier scaling study of the heterostructure to develop plasma based selective area recess etching to obtain and demonstrate, first ever reported, normally off high threshold voltage AlInN/GaN metal-insulator HEMTs with high current density of 0.7A/mm and high breakdown voltage of 350V and the highest reported threshold voltage of +1.5V. Moreover, investigation of substrate influence was also performed by fabricating and characterizing AlInN/GaN HEMTs on SiC substrate with different gate dimensions and the transport properties of the devices were discussed.
Next, the device performance has been studied by incorporating Ga in AlInN barrier. Introducing 2% Ga at the AlInN barrier layer is found to increase the current density of about 15% compared to the LM AlInN/GaN HEMTs. This issue has been studied intensively and the preliminary results indicated that even slightest deviations from atomically perfect interfaces leads to the creation of huge piezoelectric fields, increasing the carrier density at the AlInN/GaN interface.
Finally, multifinger AlInN/GaN HEMTs were fabricated to obtain large periphery (LP) devices for high power application. The heart of this work was the design and development of a high yield process technology for high performance LP AlInN/GaN HEMTs. The study of large periphery devices presented the problem of large heat dissipation. Therefore, for future work, new device fabrication and packaging processes for efficient heat dissipation from the top of the device was also proposed

Mizoguchi-Takahashi local contractions to Feng-Liu contractions
No full text[EN] In this article, we establish that any uniformly local Mizoguchi-Takahashi contraction is actually a set-valued contraction due to Feng and Liu on a metrically convex complete metric space. Through an example, we demonstrate that this result need not hold on any arbitrary metric space. Furthermore, when the metric space is compact, we derive that any Mizoguchi-Takahashi local contraction and Nadler local contraction are equivalent. Moreover, a result related to invariant best approximation is established.The first author would like to acknowledge the Ministry of Human Resource Development, India for providing financial assistance during the research work.

Twisted Turquoiseries:Emulation and Critique in Miguel de Cervantes’ La gran sultana Catalina de Oviedo
No full textCervantes’ only surviving Turkish play, La gran sultana Catalina de Oviedo (1607/8), narrates the story of a Spanish captive in the Topkapi harem whose beauty conquers the heart of Murad III. Plot and setting allow the author not only to pursue his own fascination with the ‘other’ of Western Christianity, but also to critically examine the cultural forms of this fascination circulating in Spain at the time. Thus, the play’s emulation of popular forms such as captivity tales and Byzantine martyr legends becomes an ambiguous inversion of the ideology that they harbour and even a tongue-in-cheek ideology critique

Investigations of the Tribological Effects of Engine Oil Dilution by Vegetable and Animal Fat Feedstock Biodiesel on Selected Surfaces
No full textBiodiesels have become attractive alternative fuel to replace traditional fossil fuels. Biodiesels can be used in diesel engines with no major modification, but its use leads to some degree of engine oil dilution because of biodiesel leaking and scrapping to engine oil pan. Biodiesels can be made from vegetable and animal fat feedstocks. Therefore, the fatty acid methyl ester components of biodiesel may vary upon these sources of feedstock. In this thesis work, engine oil is diluted with vegetable (canola oil, peanut oil and soybean oil biodiesel) and animal (chicken fat) feedstock biodiesels at known percentages and these mixtures are tested in a pinon-disk tribometer. In-process friction force and temperature changes are observed and specific wear on the tested surface and dilution effects on viscosity are measured. The oxidative stability of diluted engine oils is also assessed by observation. Experimental results suggest that a higher fraction of palmitic and a lower fraction of linoleic acid contents of the biodiesel play a role for providing good lubricity when mixed with the engine oil in the tested condition and animal feedstock biodiesel perform better than that of vegetable feedstock biodiesel
