    The Indian crested porcupine (Hystrix indica) is a vertebrate pest of agricultural lands and forest. The study was aimed to report the damage to local crops by the Indian crested porcupine (Hystrix indica) in the Muzaffarabad District. A survey was conducted to identify the porcupine-affected areas and assess the crop damage to the local farmers in district Muzaffarabad Azad Jammu and Kashmir (AJK) from May 2017 to October 2017. Around 19 villages were surveyed, and a sum of 191 semi-structured questionnaires was distributed among farmers. Crop damage was found highest in village Dhanni where a porcupine destroyed 175 Kg/Kanal of the crops. Regarding the total magnitude of crop loss, village Danna and Koomi kot were the most affected areas. More than half (51.8%) of the respondents in the study area suffered the economic loss within the range of 101-200,and(29.8, and (29.8%) of the people suffered losses in the range of 201-300 annually. Among all crops, maize (Zea mays) was found to be the most damaged crop ranging between 1-300 Kg annually. In the study area, porcupine also inflicted a lot of damages to some important vegetables, including spinach (Spinacia oleracea), potato (Solanum tuberosum) and onion (Allium cepa). It was estimated that, on average, 511Kg of vegetables are destroyed by porcupine every year in the agricultural land of Muzaffarabad. It was concluded that the Indian crested porcupine has a devastating effect on agriculture which is an important source of income and food for the local community. Developing an effective pest control strategy with the help of the local government and the Wildlife department could help the farmers to overcome this problem

    The place where curses are manufactured : four poets of the Vietnam War

    The Vietnam War was unique among American wars. To pinpoint its uniqueness, it was necessary to look for a non-American voice that would enable me to articulate its distinctiveness and explore the American character as observed by an Asian. Takeshi Kaiko proved to be most helpful. From his novel, Into a Black Sun, I was able to establish a working pair of 'bookends' from which to approach the poetry of Walter McDonald, Bruce Weigl, Basil T. Paquet and Steve Mason. Chapter One is devoted to those seemingly mismatched 'bookends,' Walt Whitman and General William C. Westmoreland, and their respective anthropocentric and technocentric visions of progress and the peculiarly American concept of the "open road" as they manifest themselves in Vietnam. In Chapter, Two, I analyze the war poems of Walter McDonald. As a pilot, writing primarily about flying, his poetry manifests General Westmoreland's technocentric vision of the 'road' as determined by and manifest through technology. Chapter Three focuses on the poems of Bruce Weigl. The poems analyzed portray the literal and metaphorical descent from the technocentric, 'numbed' distance of aerial warfare to the world of ground warfare, and the initiation of a 'fucking new guy,' who discovers the contours of the self's interior through a set of experiences that lead from from aerial insertion into the jungle to the degradation of burning human feces. Chapter Four, devoted to the thirteen poems of Basil T. Paquet, focuses on the continuation of the descent begun in Chapter Two. In his capacity as a medic, Paquet's entire body of poems details his quotidian tasks which entail tending the maimed, the mortally wounded and the dead. The final chapter deals with Steve Mason's JohnnY's Song, and his depiction of the plight of Vietnam veterans back in "The World" who are still trapped inside the interior landscape of their individual "ghettoes" of the soul created by their war-time experiences

    Queens of the Hill: How Title IX Fares in the Hilltop Neighborhood of Columbus, Ohio

    Get PDF
    National research indicates that Title IX of the Education Amendments of 1972 leaves Black girls behind in the pursuit of gender equity. Low rates of participation and high dropout rates in girls sports plague low-income, majority-minority high schools. This thesis investigates whether the national research holds true in Columbus, Ohio, specifically at West High School. Following from a series of interviews with coaches, teachers, and a student, I find that West High School’s athletic program is Title IX compliant, but girls at West High School still face severe barriers to sports participation. A school can comply with Title IX and fall short of equal opportunity for sports participation. Title IX leaves girls at West High School behind because it is reliant on a top-down approach of administrative punishment, threatening the loss of federal funding. To achieve authentic gender equity, West High School and other low-income, majority-minority schools must supplement Title IX with a bottom-up approach that is community and culturally centered

    First report of Fusarium avenaceum causing branch canker on pear in Turkey

    Get PDF
    Pear (Pyrus communis) is an important fruit crop in Turkey. In May 2021, canker lesions were observed in pruning wounds on approximately 70% of the pear trees cultivar Deveci in a fve-year-old orchard in Bursa province, Turkey. Disease symptoms were twig blight, brownish bark and branch canker. Twenty small pieces from branch lesions were surface disinfected with 1% NaOCl solution for 3 min and placed on potato dextrose agar. Petri dishes were incubated for 10 days at 23 °C. All colonies were Fusarium-like with the production of a yellow to rose pigment and a dark pink to red reverse with abundant white aerial mycelium

    Theocentrism is not Anthropocentric: An Enlightened Environmentalist Reading of the Holy Qur'an

    Get PDF
    Humans should come down from their destructive arrogance stool to take the best cognizance of the fact that nature is a sculptural work of God. Their failure to realise this fact has been responsible for their formulation of the secular environmental theories which include; anthropocentrism, zoocentrism, biocentrism, ecocentrism, and the hybrid eco-feminism. Romanced with these theories the Holy Scriptures are also implicated by reading them in the light of one of these theories and considered anthropocentric. As a matter of fact, the best of these secular theories should never be taken to be representing theocentric view of the environment

    Animating potential for intensities and becoming in writing: challenging discursively constructed structures and writing conventions in academia through the use of storying and other post qualitative inquiries

    Written for everyone ever denied the opportunity of fulfilling their academic potential, this is ‘Chloe’s story’. Using composite selves, a phrase chosen to indicate multiplicities and movement, to story both the initial event leading to ‘Chloe’s’ immediate withdrawal from a Further Education college and an imaginary second chance to support her whilst at university, this Deleuzo-Guattarian (2015a) ‘assemblage’ of post qualitative inquiries offers challenge to discursively constructed structures and writing conventions in academia. Adopting a posthuman approach to theorising to shift attention towards affects and intensities always relationally in action in multiple ‘assemblages’, these inquiries aim to decentre individual ‘lecturer’ and ‘student’ identities. Illuminating movements and moments quivering with potential for change, then, hoping thereby to generate second chances for all, different approaches to writing are exemplified which trouble those academic constraints by fostering inquiry and speculation: moving away from ‘what is’ towards ‘what if’. With the formatting of this thesis itself also always troubling the rigid Deleuzo-Guattarian (2015a) ‘segmentary lines’ structuring orthodox academic practice, imbricated in these inquiries are attempts to exemplify Manning’s (2015; 2016) ‘artfulness’ through shifts in thinking within and around an emerging PhD thesis. As writing resists organising, the verb thesisising comes into play to describe the processes involved in creating this always-moving thesis. Using ‘landing sites’ (Arakawa and Gins, 2009) as a landscaping device, freely creating emerging ‘lines of flight’ (Deleuze and Guattari, 2015a) so often denied to students forced to adhere to strict academic conventions, this ‘movement-moving’ (Manning, 2014) opens up opportunities for change as in Manning’s (2016) ‘research-creation’. Arguing for a moving away from writing-representing towards writing-inquiring, towards a writing ‘that does’ (Wyatt and Gale, 2018: 127), and toward writing as immanent doing, it is hoped to animate potential for intensities and becoming in writing, offering opportunities and glimmerings of the not-yet-known

    Metaphors of London fog, smoke and mist in Victorian and Edwardian Art and Literature

    Get PDF
    Julian Wolfreys has argued that after 1850 writers employed stock images of the city without allowing them to transform their texts. This thesis argues, on the contrary, that metaphorical uses of London fog were complex and subtle during the Victorian and Edwardian periods, at least until 1914. Fog represented, in particular, formlessness and the dissolution of boundaries. Examining the idea of fog in literature, verse, newspaper accounts and journal articles, as well as in the visual arts, as part of a common discourse about London and the state of its inhabitants, this thesis charts how the metaphorical appropriation of this idea changed over time. Four of Dickens's novels are used to track his use of fog as part of a discourse of the natural and unnatural in individual and society, identifying it with London in progressively more negative terms. Visual representations of fog by Constable, Turner, Whistler, Monet, Markino, O'Connor, Roberts and Wyllie and Coburn showed an increasing readiness to engage with this discourse. Social tensions in the city in the 1880s were articulated in art as well as in fiction. Authors like Hay and Barr showed the destruction of London by its fog because of its inhabitants' supposed degeneracy. As the social threat receded, apocalyptic scenarios gave way to a more optimistic view in the work of Owen and others. Henry James used fog as a metaphorical representation of the boundaries of gendered behaviour in public, and the problems faced by women who crossed them. The dissertation also examines fog and individual transgression, in novels and short stories by Lowndes, Stevenson, Conan Doyle and Joseph Conrad. After 1914, fog was no more than a crude signifier of Victorian London in literature, film and, later, television, deployed as a cliche instead of the subtle metaphorical idea discussed in this thesis

    The temporality of rhetoric: the spatialization of time in modern criticism

    Get PDF
    Every conception of criticism conceals a notion of time which informs the manner in which the critic conceives of history, representation and criticism itself. This thesis reveals the philosophies of time inherent in certain key modern critical concepts: allegory, irony and the sublime. Each concept opens a breach in time, a disruption of chronology. In each case this gap or aporia is emphatically closed, elided or denied. Taking the philosophy of time elaborated by Giorgio Agamben as an introductory proposition, my argument turns in Chapter One to the allegorical temporality which Walter Benjamin sees as the time of photography. The second chapter examines the aesthetics of the sublime as melancholic or mournful untimeliness. In Chapter Three, Paul de Man's conception of irony provides an exemplary instance of the denial of this troubling temporal predicament. In opposition to the foreclosure of the disturbing temporalities of criticism, history and representation, the thesis proposes a fundamental rethinking of the philosophy of time as it relates to these categories of reflection. In a reading of an inaugural meditation on the nature of time, and in examining certain key contemporary philosophical and critical texts, I argue for a critical attendance to that which eludes those modes of thought that attempt to map time as a recognizable and essentially spatial field. The Confessions of Augustine provide, in the fourth chapter, a model for thinking through the problems set up earlier: Augustine affords us, precisely, a means of conceiving of the gap or the interim. In the final chapter, this concept is developed with reference to the criticism of Arnold and Eliot, the fiction of Virginia Woolf and the philosophy of cinema derived from Deleuze and Lyotard. In conclusion, the philosophical implications of the thesis are placed in relation to a conception of the untimeliness of death

    Biocontrol as a key component to manage brown rot on cherry

    Get PDF
    Brown rot, caused by Monilinia spp., is one of the most important diseases in stone fruits worldwide. Brown rot can cause blossom wilts and fruit rots in the orchard as well as latent infections of fruit, leading to post-harvest fruit decaying. Current control methods rely on scheduled spraying of fungicides. However, the continuing pressure to reduce fungicide use has seen an increase in research into alternative management methods, such as biological control. NIAB EMR recently identified two microbes that significantly reduced sporulation of Monilinia laxa under laboratory conditions. These two isolates were a bacterial species Bacillus subtilis (B91) and yeast-like fungus Aureobasidium pullulans (Y126) and are currently being formulated into commercial products. We are investigating how to optimise the use of these two potential biocontrol products in practice, in terms of suppressing Monilinia sporulation on overwintered mummies and preventing infection of blossoms and fruits. When applied to mummified fruits in winter Y126’s population was stable through the winter but at a low concentration. The B91 survived a little longer with the population reaching that of the control group by week 4. Neither Biological control (BCA) treatments had an affected the population of M. laxa when compared to the control treatment of sterile distilled water. The interaction time between the BCAs and M. laxa showed the longer the interaction time the lower the spore count of M. laxa. Another study was performed looking into the ability of our BCAs to colonise and survive on blossoms. B91 did not survive well on blossoms but could survive on fruits. However, its antagonistic compounds need to be in relatively high concentration to be effective against M. laxa. Therefore, it is best used as a fungicide, ensuring the antagonistic compounds are at a high concentration when applied in the field. Y126 can persist throughout the season and was marginally, though not statistically significantly, more effective at long term reduction in M. laxa. This could be because Y126 works through competition, therefore the interaction time with the pathogen could be important for efficacy and something worth investigating further. The difference between the BCAs highlights the need to understand each BCA’s ecology to ensure maximum efficacy. In a latent infection experiment, we inoculated trees with M. laxa and then treated them with the two biocontrol isolates two weeks before harvest. Post-harvest disease development was assessed after four days of storage in 2019 and two weeks in 2020. There was a significant reduction in rot incidence (p < 0.001) of 29% (Y126) and 27% (B91) in 2019 and 62 % (Y126) and 80 % (B91) in 2020 when the harvested fruit was stored at cold store levels. With new products to be introduced into the environment, it's important to understand the effects they may have on the plant's microbiome. Using next-generation sequencing techniques, we looked at the impact B91 and Y126 has on the blossom and cherry microbiomes. There was a treatment effect in both the bacterial and fungal communities on the blossom and ripe cherry. But the biggest variability was between blocks (Geographical effect) and between the years in which we experimented (p < 0.0001). This research will assist in the development of management strategies, especially spray timings for brown rot on stone fruit, integrating BCAs with other management practices
