Indigenous fishing gears in Suraha Lake, Ballia, Uttar Pradesh, India
PK Srivastava,SJ Srivastava
Journal of Wetlands Ecology , 2011, DOI: 10.3126/jowe.v5i0.5156
Abstract: The study aimed at assessing the indigenous fishing methods adopted by the fishermen in Suraha Lake. Survey was conducted during August 2002 - July 2004. Information was collected through participatory rapid appraisal covering the entire lake and four fishermen villages viz Mairitar, Surajpura, Kaithauli and Basantpur. Study indicated that various types of local indigenous traditional fishing gears are used by fishers for commercial exploitation of the lake. Plank-built boats (Dingi) were used in the fishing. These boats are small and light and prepared locally by fishers. Gill net and cast net were the main gears and contributed more then 80% of the total fish catch of the lake. Indigenous fishing gears comprising gill nets, cast nets, traps, etc., have been discussed showing their modus operandi . Key words : Indigenous fishing methods; suraha lake DOI: http://dx.doi.org/10.3126/jowe.v5i0.5156 J Wet Eco 2011 (5): 73-78

African Journal of Biotechnology , 2008,
Abstract: The phylogenetic relationships of 13 Jatropha genotypes from different parts of the India were analysed using 34 polymerase chain reaction (PCR) markers (20 random amplified polymorphic DNAs (RAPDs) and 14 inter simple sequence repeats (ISSRs)). Amplification of genomic DNA of the 13 genotypes, using RAPD analysis, yielded 107 fragments that could be scored, of which 91 were polymorphic, with an average of 4.55 polymorphic fragments per primer. Number of amplified fragments ranged from one (OPA20, OPB19, OPD13) to nine (OPA18) and which varied in size from 200 to 2,500 bp. Percentage of polymorphism ranged from 40% (OPB18) to a maximum of 100% (14 primers). Resolution power ranged from a minimum of 0.153 (OPA20, OPB19) to a maximum of 11.23 (OPB15). Out of 25 ISSR primers used, 14 were able to amplify. These primers produced 81 bands across 13 genotypes, of which 62 were polymorphic. The number of amplified fragment ranging from two (ISSR 7, ISSR 8, ISSR 16) to nine (ISSR 12) and which varied in size from 200 to 2,500 bp. Of the 81 fragments amplified bands, 62 were polymorphic, with an average of 4.42 polymorphic fragments per primer. Percentage of polymorphism ranged from 37.5% (ISSR 2, ISSR10) to a maximum of 100% (seven primers). The primers based on poly (GA) produced maximum number of bands (nine) while, poly (AT) and many other motifs gave no amplification at all with any of these thirteen genotypes. RAPD markers were more efficient than the ISSR assay with regards to polymorphism detection, as they detected 84.26% as compared to 76.54% for ISSR markers. But, resolving power (Rp), average bands per primer, Nei’s genetic diversity (h), Shannon’s Information Index (I), total genotype diversity among population (Ht), within population diversity (Hs) and gene flow (Nm) estimates were more for ISSR (7.098, 5.79, 0.245, 0.374, 0.244, 0.137 and 0.635, respectively) as compared to RAPD markers (5.669, 5.35, 0.225, 0.359, 0.225, 0.115 and 0.518, respectively). The regression test between the two Nei’s genetic diversity indexes gave r2 = 0.3318, showing low regression between RAPD and ISSR based similarities. Regression value for ISSR and ISSR + RAPD combined data is moderate (0.6027), while it is maximum for RAPD and ISSR+RAPD based similarities (0.9125). Thus both the markers are equally important for genetic diversity analysis in Jatropha curcas. Clustering of genotypes within groups was not similar when RAPD and ISSR derived dendrogram were compared, whereas the pattern of clustering of the genotypes remained more or less the same in RAPD and combined data of RAPD + ISSR. Principal Coordinates Analysis (PCA) analysis was also employed to evaluate the resolving power of the markers to differentiate between the genotypes. These analyses, carried out for both (ISSR and RAPD) markers, allowed us to identify four main groups partially corresponding to the four J. curcas collection sites. The results of the present study can be seen as a starting poin
Students’ Reflections on Teaching Methodology in Anatomy
Jyoti Chopra, Anita Rani, Archana Rani, RK Deewan, AK Srivastava, PK Sharma
Asian Journal of Medical Sciences , 2014, DOI: 10.3126/ajms.v5i1.8039
Abstract: Objective : With technological evolution, use of power point presentation has been increased tremendously for classroom teachings in medical education. There is dearth of information that whether this technology is really liked by the students in anatomy or not. Therefore present study was conducted to assess which methodology of teaching anatomy was preferred by students: traditional (chalk & black-board), computer assisted or both when combined. Methods : A questionnaire based study was conducted that involved 250 1st year MBBS students. Students were asked to fill semi structured questionnaire that contained closed and open ended questions regarding teaching methodology. Results & Conclusion : 70.37% students favored combination of power point presentations along with traditional method, 25.93% preferred chalk and blackboard method and only 3.7% students opined that power point presentations should be the sole method of teaching. Therefore the study concludes that traditional method of lecture delivery in anatomy should be carefully amalgamated with power point presentations to meet the aspirations of students and to combat the limitations of chalk and board method.

Morphological Changes and Antioxidant Activity of Stevia rebaudiana under Water Stress  [PDF]
Shilpi Srivastava, Malvika Srivastava
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.522357
Abstract:

Stevia rebaudiana, a herbaceous perennial shrub contains steviol glycosides, as an alternative source of sugar for diabetic patients. Water being an integral part plays a vital role in the maintenance of plant life. Availability of water is one of the limiting factors determining plant distribution and survival in natural ecosystem. The objective of this study was to investigate the ability of tolerance of Stevia plants to water stress. Potted plants of Stevia were subjected to different levels of water regimes (100 ml, 200 ml, 300 ml) per day, whereas control plants were watered daily with about 400 ml water. Plant height, leaf area, electrolyte leakage and antioxidant enzyme activity (peroxidase and catalase) were assayed during the experimental period. All these parameters were severely affected under water stress condition. Stress treatment caused an increase in electrolyte leakage compared to control. Plant height decreased under severe stress condition whereas a sharp increase in antioxidant enzyme activity was observed in stressed plants as compared to untreated control plants. Our experiment emphasizes the importance of proper watering schedule for the cultivation of Stevia as an agricultural crop to meet the challenges for sugar and energy crisis.

Les “démons crachés” de l’autre République de Serge Armand Zanzala. Une métaphore historique dans une période chaotique
PK Mwepu
Tydskrif vir letterkunde , 2011,
Abstract: Published in 2007 by L’Harmattan, the novel Les “démons crachés” de l’autre République by Serge Armand Zanzala challenges its readers to rediscover the period between 1993 and 2002. During that period, which lasted almost a decade, Congo-Brazzaville, the writer’s country of origin, was ravaged by violent wars. In his novel, Zanzala has attempted to reconstruct the real facts of this conflict by depicting characters that embody an inhuman and homicidal aristocracy. Through Congo-Brazzaville, one can also easily discover Congo-Kinshasa as the pan Congolese spirit is being expressed throughout the novel. This paper aims to demonstrate several ways in which and reasons why the writer takes position and uses fiction to restore the history of his country. Literary fiction has been perceived as an instrument par excellence to combat the abuse of political or military power. Furthermore, it will be demonstrated how and why the use of violence by politicians is depicted throughout the novel as cannibalism. The paper will finally analyse the way Zanzala uses the fabulous as a remedy to cure the barbaric acts orchestrated by politicians against civilians.
La femme et sa lutte de libération dans l'oeuvre d'Henri Lopes
PK Mwepu
Tydskrif vir letterkunde , 2008,
Abstract: Born in Kinshasa, Congo, on 12 September 1937, but a national of Congo (Brazzaville), Henri Lopes is one of those African writers who, were not only educated but also lived in Europe where a certain portion of their literary work was produced. Being a politician and writer, one can easily glean, through Lopes' works, a complete picture of despotic postcolonial mismanagement of political affairs coupled with a dire dearth of humanism. Literary works such as Tribaliques (Tribaliks, 1971), La nouvelle Romance (The New Romance, 1976), Sans tam-tam (Without Drum, 1977), Le Pleurer-Rire (The Crying-Laughter, 1982) and Sur l'autre rive (On the Other Shore, 1992) depict a particular worldview as well as an understanding of the overarching reality of a young Africa that had just attained political independence. However, while Lopes' works decry the shortcomings of Africa's postcolonial ruling class, it is important to note that the author appears to pay equal attention to questions relating to the perception and critical analysis of the status of women in Africa. Notwithstanding his male gender status, in his rather original approach, Lopes lends women a revolutionary voice with which they address and search for solutions to their problems themselves.
Culturalisme et réflexion existentialiste— Une lecture de Retour de manivelle de Julien Kilanga Musinde
PK Mwepu
Tydskrif vir letterkunde , 2013,
Abstract: Culturalism and existentialist thought—A reading of Julien Kilanga Musinde’s "Retour de manivelle" Published in 2008, the novel Retour de manivelle by Julien Kilanga Musinde revives the unfinished debate related to the search of identity in African writing. The universe depicted represents the modern society and Musinde’s main character is changing as fast as he relocates to a different society. The author depicts this flexibility as a strength that commands the adaptability of the character without suppressing the initial culture of the protagonist. Musinde chooses to freely express his fantasy and, at the same time, integrate his subjective world vision and multidimensional scholarship in the interpretation of the identity. The question of culture being central to the novel, the paper is aimed at demonstrating, however, that the culture that is depicted as both exclusive and dynamic in Musinde’s work should be understood mainly in cyclic perception in which both the starting and the arrival points are joining in a unique individual subjectivity, such a subjectivity having the potential of engendering a new discourse by attempting to juxtapose conflicting ways of life. The paper also demonstrates how Musinde distances himself from the materialistic world vision commonly expressed by existentialists and Epicurean philosophers. This attitude allows the author to reflect on the interconnectivity between the immediate empirical reality and the world beyond from the perspective of a transnational African intellectual in a globalizing world.
Women and their struggle for emancipation in Lopes' works
PK Mwepu
Tydskrif vir letterkunde , 2008,
Abstract: Né le 12 septembre 1937 à Kinshasa, en Congo, mais se réclamant de nationalité congolaise de Brazzaville, Henri Lopes est l'un des écrivains africains qui ont non seulement été éduqués en Europe mais en plus ont pu y vivre tout en y produisant une partie de leur oeuvre littéraire. A la fois homme politique et écrivain, il est facile de dénicher, à travers sa plume, la description achevée d'une gestion politique postcoloniale despotique à laquelle s'ajoute le manque d'humanisme porté à son paroxysme. Les oeuvres comme Tribaliques (1971), La Nouvelle romance (1976), Sans tam-tam (1977) Le Pleurer-Rire (1982) et Sur l'autre rive (1992) constituent à la fois une vision du monde et une appréhension de la réalité totale et englobante d'une Afrique jeune au lendemain des indépendances politiques. Pourtant, bien que l'oeuvre de Lopes stigmatise les faiblesses de la classe dirigeante africaine postcoloniale, il est important de remarquer qu'à travers son écriture l'auteur semble être intéressé également par les questions en rapport avec la vision et la critique de la condition de la femme africaine. Sa manière particulière de l'aborder consiste à placer une voix révolutionnaire dans la bouche des femmes elles-mêmes qui parlent de leur condition et cherchent des solutions, bien que l'auteur soit lui-même un homme.
