The study area is Dumuria Upazila which is a 30 square km land area in the outskirt of Khulna which is the third largest city of Bangladesh located in the south-western region of Bangladesh. Agro-products produced in the Dumuria Upazila and then sold in the areas including Dumuria Bazar and Gollamari Bazar which are peri-urban locations of Khulna city. The particular objectives of this study were to identify different value chains of agroforestry products, the relationship of various intermediaries within it, and to explore the impact of agroforestry practices on the socioeconomic condition of the local population. The assessment was performed by using multistage sampling of 80 households using a semi-structured questionnaire, and 30 intermediaries were included on convenience basis for tracing the structure of market linkage and existing problems, in the marketing of agro-products in the study area. Explored network structures of the value chain have revealed that both the marketing of agroforestry crops and timber, include the intermediaries that have contributed to different forms of value-addition to the original product and produced higher gains for the participants in the value chain. Value chain participants in the point of origin of the products, farmers and households, reported being discriminated in terms of price taking while end-market intermediaries were found to absorb major shares of the total gain originated in the value chain. The farmers were neutral in terms of satisfaction in case of purchase by the government, while the intermediaries were dissatisfied with the same. Findings of this study contributes in generating understanding the process of value creation, power structure, and gain sharing in the localized natural resources-based value chains.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132954461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present research has investigated the morphological variability of the gastropod molluscs (Pila globosa) in the six localities of south-western coastal Bangladesh (such as, Khulna, Bagerhat, Satkhira, Gopalganj, Pirojpur and Jessore). A total of 2160 gastropod samples (Pila globosa) were collected from July to December monthly over the two consecutive years of 2013 and 2014. The results of the analyses revealed that the maximum monthly mean values of the dry shell mass and the dry body mass were found in November, indicating the complete growth and development of the gastropods in the coastal environment. One-way ANOVA and ANCOVA show that there is a significant morphological variability of Pila globosa among different localities in the south-west coastal Bangladesh, while the covariate of water salinity significantly affects the aperture length of it; the covariate of electrical conductivity of soil significantly affects both the height and aperture length; the covariate of sodium contents of the soil significantly affects the aperture length of the gastropod mollusc. The results also revealed that the morphological variability of the mollusc P. globosa is linked to complex ecological systems and habitat variation.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127531065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Themes like regeneration of wisdom, distribution, and effect of power and pelf, human and divine justice, and man’s relationship with man and nature, are all presented on a universal scale, spatial and temporal, passing from the palace to the hovel, from the court to the heath, and from moments of folly to moments of enlightenment through moments of purgatorial sufferings. This universal scale can be regarded as connected to the political contexts of Britain, modeled on the prototypical and primary unit of a family. And since family, which involves principally the begetter and the begotten that also has the potential of begetting, is the primary and fundamental unit of the whole universe from both human and animal perspectives of life, this paper seeks to investigate how the familial background of the parent-child relationship in King Lear is portrayed against the backdrop of the kingdom and the universe. In order to do so, these three units – family, kingdom, and in natural and metaphysical senses the universe – are considered to be deeply interconnected with human relationships, corresponding consecutively to its psychological, material, and spiritual aspects. Shakespeare has illuminated the tragic truths about the relationship between the parents and their children by showing a profound interaction between the family, kingdom, and the universe with respect to their corresponding psychological, material, and spiritual aspects.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123112129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are several measures of various characteristics, each of which has its own justification in flood protection. The concepts of vulnerability, hazard, and risk have been extensively used in various disciplines with different meanings, impeding cross-disciplinary cooperation for dealing with hazardous events. In Nigeria, there has been an occurrence of flooding and many households have been rendered homeless and many lives have been lost due to this devastating issue. This article aimed to examine flood vulnerability and possible adaptation practices for residential buildings as well as the potential for resiliency in the event of its occurrence. The objective was to propose appropriate resilient strategies to mitigate flood risk in Abuja, Nigeria. The paper adopts a purposive sampling technique in the selection of some areas for the study. A structured questionnaire survey was used to get information on the residents, and also a site risk assessment was taken on the selected areas. A total of 174 questionnaires were administered, with a valid rate of 96.6% and a reliability value of 0.606. The result shows that an average percentage of residential areas are affected by floods with low resilience strategies. The study concludes that the government should have policies to set the rules of implementation and possible resilience strategies to mitigate the occurrence of floods for the residents.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123824116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lectins that agglutinate erythrocytes are called hemagglutinin. These compounds occur in various organisms including plants. In this study, twenty edible vegetables were subjected to screen for haemagglutination and lectin activity. Lectin activity was assessed by measuring the inhibition ability of haemagglutination by different sugars. PBS (Phosphate Buffer Saline) treated homogenate was tested for haemagglutination against erythrocytes suspension, and inhibition of agglutination was determined by serially diluted sugar solution. The results of this study demonstrated that one homogenate among the homogenates of 20 vegetables was found to be capable of human erythrocyte agglutination. The Ipomoea aquatica homogenate shown positive haemagglutination reaction against red blood cells (RBCs) with HA titer value of 4 HA-U/25uL, and four out of seven sugars were able to inhibit RBCs agglutination. Among the four sugars, two are potent inhibitors of agglutination. The neutralization of haemagglutination by four monosaccharides provides a suggestion that the lectin present in I. aquatica may be multivalent carbohydrate binding hemagglutinin. This is the first report to identify that Ipomoea aquatica contains lectin protein which is a polyvalent sugar binding lectin and specific for glucose, galactose, mannose and N-Acetyl-D-Glucosamine.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131023081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both surface-inhabiting (Glyphosate) and root-inhabiting (Paraquat) herbicides were applied for six months in five different combinations (100% Glyphosate, 75% Glyphosate + 25% Paraquat, 50% Glyphosate + 50% Paraquat, 25% Glyphosate + 75% Paraquat, and 100% Paraquat) and the percentage coverage was measured for each experimental plot. Results from the study showed that all shading and chemical combinations of Glyphosate and Paraquat significantly reduced the percentage coverage of S. trilobata in each experimental plot (p < 0.05). However, the shading and Paraquat-dominated combinations reduced the coverage slowly compared to the Glyphosate-dominated ones. Among five different combinations, Paraquat-dominated herbicides were less effective in controlling the species. On the other hand, the Glyphosate-dominated combinations completely eradicated the species within a week but increased thereafter. Meanwhile, the seasonal variation was found to be highly significant (p < 0.0001) among treatments, and a significant reduction was observed in winter compared to the monsoon. The results of this study highlighted that the Glyphosate-dominated combinations were the fastest, while the Paraquat-dominated combinations and shading were slower control methods.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127085007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He portrays women as primarily endowed with vital reproductivity and men as endowed with potential intellectuality. Though in this philosophical comedy, he expounds to some length the doctrine of Life Force, he does not attempt to approach the issue in a purely philosophical manner. He contrasts men’s intellectualism and romanticism and women’s active vitality and practical immorality, and thus his women are motivated to desire men for marriage, and his men either harbour romantic illusions about women or engage in intellectual discussion about man-woman relationship before attempting to escape from the women who are pursuing them for marriage. In the prefatory note to the play, Shaw defends men’s intellectual view of this relationship, and as the writer of this comedy, he represents women as if they are the queen bees guided by the Life Force, which forces them to mark out men as their mates and their subsequent victims. The playwright represents men as finally capitulating to such desires of women, though all for the sake of this Life Force, which is purposed to produce intellectually advanced supermen. Though Shaw uses this drone-bee relation as a motif to produce comical effects, with this he both highlights the man-woman relationship and makes it clear that this concept of the Life Force cannot be taken too seriously.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121866265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap, adopting a mixed-method approach of data collection this study selected two most disaster-prone areas namely, Dacope Upazila and Koyra Upazila, of Khulna District in Bangladesh to collect primary data. The findings of this study reveal that in some areas religious institutions play a significant role through disseminating disaster-related news, providing social supports immediately after a disaster, and acting as a victim support center. Similarly, religious masters as well as other religious leaders have played a leadership role to bind people together. The findings of this study also indicate that the most important role of religion in disaster management was psychological. Besides, religion increase the capacity of community management through enhancing moral responsibilities. However, the lack of coordination of these potential cultural elements remains unused in the field of disaster management. Therefore, through this study, the researcher would like to call upon policymakers' attention to integrating religious elements with other disaster risk reduction elements.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132175880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine its preliminary phytochemical and some biological properties. For this, fresh leaves of A. carambola were extracted (hot and cold) with ethanol, which was then fractionated with n-hexane and chloroform. Following a preliminary investigation of phytochemicals, radical scavenging, membrane stabilizing, alpha-glucosidase inhibitory, and clot lysis effects were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, egg albumin model, alpha-amylase assay, and human blood clot lysis assay, respectively using suitable reference standards. The results suggest that A. carambola contains alkaloids, glycosides, steroids, tannins, flavonoids, saponins, and reducing sugars. All the organic fractions demonstrated significant (p <0.05) radical scavenging, membrane stabilizing, alpha-glucosidase inhibitory, and clot lysis activities in a concentration-dependent approach. Except for DPPH radical scavenging, the ethanol fraction showed better activities than the n-hexane and chloroform fractions. In summary, A. carambola might be a potential source of antioxidant, anti-inflammatory, hypoglycemic, and atherothrombolytic agents.

Violence being plentiful and readily available to this increasing degree in cinema, it has become a pertinent subject of deep analysis in film studies to decipher all the different implications embedded in the violent acts depicted on celluloid. Christopher Nolan’s The Dark Knight (2008) is a film that portrays violent tales revolving around the characters of Batman and the Joker. In fact, both heroic and evil characters perform violent acts in the film. Using Jacques Derrida’s post-structuralist idea of deconstruction, binary oppositions revolving around violence in the film - such as violence perpetrated by hero/villain, violence in/out of context, justified/unjustified violence - can be analysed. Such analysis of binary oppositions concerning violence can then lead to the discovery of plurality of meaning. As deconstruction aims to uncover the unconscious voices of a text by identifying internal contradictions, binary oppositions or inconsistencies within a text, it is an effective lens to study such complex implications regarding violence. Thus, a single violent act depicted in the film can be deconstructed in different contexts to strip off its singular meaning intended by the filmmakers.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126447531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
