African monsoons Part 1 : Climatological structure and circulation

A recent (1979-1996) NCEP/NCAR reanalysis dataset is utilized to study the structure and characteristics of the time-mean meteorological fields over the continent of Africa and surrounding oceans during February and August when the seasonal monsoons are normally at their peak intensity. The vertical structure, revealed in zonal and meridional sections over different parts of the continent, bring out the dominant influences of the neighbouring oceans and topography in the formation and distribution of monsoon troughs and ridges and associated dry and wet zones. Vertical circulations reveal a symbiotic relationship between the tropical monsoons and the subtropical deserts of the two hemispheres. Some salient features of the African monsoons, such as the formation of double equatorial troughs and their movement following change of season, are discussed and compared with similar features observed elsewhere over the world.

Some salient features of the Bay of Bengal Cyclone of November 1989

The cyclone which occurred in the Bay of Bengal during November 1989 produced relatively less rainfall and the damage though intensive was confined to a relatively small area. After landfall the system weakened rapidly. Salient features of the cyclone are discus3ed and a comparative study has also been made with the cyclone of November 1984 and the results presented.

Interdisciplinary perspective-taking within argumentation: students’ strategies across science and religious education

The importance of developing students’ argumentation skills is well established across the curriculum: students should grasp how claims are made and supported in different disciplines. One challenge is to follow and thereby agree with or critique the arguments of others, which requires perspective-taking, in tracing these other reasons and reasoning. This challenge is increased when disciplines construct argumentation and perspective-taking differently. Here, we consider the role of perspective-taking in argumentation within and between science education and pluralistic religious education, where the former aims at the justification of scientific claims and the latter at both an empathetic understanding of different religions and worldviews, and personal reasoning. We interpretively analyze student data to identify salient features of students’ strategies to perspective-taking within argumentation. Data from 324 pupils across nine schools are explored in relation to students’ challenges in perspective-taking, strategies for perspective-taking within argumentation, and the use of perspective-taking to construct personal argumentation. The analysis shows some barriers to perspective-taking within argumentation, the range of students’ perspective-taking strategies within argumentation, and how personal argumentation could hermeneutically build upon perspective-taking strategies. The importance and implications of perspective-taking within argumentation across the curriculum are considered highlighting challenges in the etic/emic shift, both within the individual subject as well as across them, and some reflections on how this provides a fresh pedagogical perspective on the science/religions debate are made. To end, we conclude with the wider challenges for disciplines and perspective-taking across schooling and university.

Immune mediated Lesions of the oral cavity: A scrupulously researched review

Oral mucosa may be the first site to manifest protean signs and symptoms in immune mediated diseases. Therefore, it is of paramount importance to have a thorough and vast knowledge about various diseases. It is the role of Oral and Maxillofacial Diagnostician to diagnose the lesions according to their salient features.In this review article, we aim to describe the immune mediated oral lesions, their clinical features, investigations and management.

Communicating across educational boundaries: accommodation patterns in adolescents’ online interactions

This paper studies linguistic accommodation patterns in a large corpus of private online conversations produced by Flemish secondary school students. We use Poisson models to examine whether the teenagers adjust their writing style depending on their interlocutor’s educational profile, while also taking into account the extent to which these adaptation patterns are influenced by the authors’ own educational background or by other aspects of their socio-demographic profiles. The corpus does reveal accommodation patterns, but the adjustments do not always mirror variation patterns related to educational profiles. While salient features like expressive markers seem to lead to pattern-matching, less salient features appear less prone to ‘adequate’ adjustment. Lack of familiarity with the online behavior of students from other educational tracks is a factor too, since online communication clearly proceeds primarily within ‘same-education’ networks. The focus on cross-educational communication is quite unique in this respect and highly relevant from a sociological perspective.

Understanding Musical Instants

We may typically experience music as continuous streams of sound and associated body motion, yet we may also perceive music as sequences of more discontinuous events, or as strings of chunks with multimodal sensations of sound and body motion, chunks that can be called ‘sound-motion objects’. The focus in this chapter is on how such sound-motion objects emerge at intermittent points in time called ‘musical instants’, and how musical instants are necessary in order to perceive salient features in music such as of timbre, pitch, texture, contour, and overall stylistic and affective features. The emergence of musical instants is also understood as based on the combined constraints of musical instruments, sound-producing body motion, and music perception, also suggesting that understanding musical instants may have practical applications in making music.

Salient Features of Feminist Literary Criticism

Feminist literary criticism as criticism schools is marked by gender, widespread gender awareness, and feminine consciousness is its elementary characteristics. This study introduces the different phases of Feminism through various insidious social and cultural mores. The main objective of this study to Criticism the Salient Features of Feminist Literary. The main content of this paper is divided into three aspects, the first, second, and third wave of feminism from the 19th century to date. Methodology Employed based on qualitative research. The secondary sources of this study are taken from various books, articles, diaries, proposals, official records, archives, Govt. Gazetteers, Manuals and sites, and so on.

Improving the Performance of Deduplication-Based Backup Systems via Container Utilization Based Hot Fingerprint Entry Distilling

Data deduplication techniques construct an index consisting of fingerprint entries to identify and eliminate duplicated copies of repeating data. The bottleneck of disk-based index lookup and data fragmentation caused by eliminating duplicated chunks are two challenging issues in data deduplication. Deduplication-based backup systems generally employ containers storing contiguous chunks together with their fingerprints to preserve data locality for alleviating the two issues, which is still inadequate. To address these two issues, we propose a container utilization based hot fingerprint entry distilling strategy to improve the performance of deduplication-based backup systems. We divide the index into three parts: hot fingerprint entries, fragmented fingerprint entries, and useless fingerprint entries. A container with utilization smaller than a given threshold is called a sparse container . Fingerprint entries that point to non-sparse containers are hot fingerprint entries. For the remaining fingerprint entries, if a fingerprint entry matches any fingerprint of forthcoming backup chunks, it is classified as a fragmented fingerprint entry. Otherwise, it is classified as a useless fingerprint entry. We observe that hot fingerprint entries account for a small part of the index, whereas the remaining fingerprint entries account for the majority of the index. This intriguing observation inspires us to develop a hot fingerprint entry distilling approach named HID . HID segregates useless fingerprint entries from the index to improve memory utilization and bypass disk accesses. In addition, HID separates fragmented fingerprint entries to make a deduplication-based backup system directly rewrite fragmented chunks, thereby alleviating adverse fragmentation. Moreover, HID introduces a feature to treat fragmented chunks as unique chunks. This feature compensates for the shortcoming that a Bloom filter cannot directly identify certain duplicated chunks (i.e., the fragmented chunks). To take full advantage of the preceding feature, we propose an evolved HID strategy called EHID . EHID incorporates a Bloom filter, to which only hot fingerprints are mapped. In doing so, EHID exhibits two salient features: (i) EHID avoids disk accesses to identify unique chunks and the fragmented chunks; (ii) EHID slashes the false positive rate of the integrated Bloom filter. These salient features push EHID into the high-efficiency mode. Our experimental results show our approach reduces the average memory overhead of the index by 34.11% and 25.13% when using the Linux dataset and the FSL dataset, respectively. Furthermore, compared with the state-of-the-art method HAR, EHID boosts the average backup throughput by up to a factor of 2.25 with the Linux dataset, and EHID reduces the average disk I/O traffic by up to 66.21% when it comes to the FSL dataset. EHID also marginally improves the system's restore performance.
