    Senslide: a distributed landslide prediction system

    We describe the design, implementation, and current status of Senslide, a distributed sensor system aimed at predicting landslides in the hilly regions of western India. Landslides in this region occur during the monsoon rains and cause significant damage to property and lives. Unlike existing solutions that detect landslides in this region, our goal is to predict them before they occur. Also, unlike previous efforts that use a few but expensive sensors to measure slope stability, our solution uses a large number of inexpensive sensor nodes inter-connected by a wireless network. Our system software is designed to tolerate the increased failures such inexpensive components may entail. We have implemented our design in the small on a laboratory testbed of 65 sensor nodes, and present results from that testbed as well as simulation results for larger systems up to 400 sensor nodes. Our results are sufficiently encouraging that we intend to do a field test of the system during the monsoon season in India

    Perceived fear of COVID-19 and its associated factors among Nepalese older adults in eastern Nepal : a cross-sectional study

    Coronavirus disease 2019 (COVID-19) has affected all age groups worldwide, but older adults have been affected greatly with an increased risk of severe illness and mortality. Nepal is struggling with the COVID-19 pandemic. The normal life of older adults, one of the vulnerable populations to COVID-19 infection, has been primarily impacted. The current evidence shows that the COVID-19 virus strains are deadly, and non-compliance to standard protocols can have serious consequences, increasing fear among older adults. This study assessed the perceived fear of COVID-19 and associated factors among older adults in eastern Nepal. Methods A cross-sectional study was conducted between July and September 2020 among 847 older adults (?60 years) residing in three districts of eastern Nepal. Perceived fear of COVID-19 was measured using the seven-item Fear of COVID-19 Scale (FCV-19S). Multivariate logistic regression identified the factors associated with COVID-19 fear. Results The mean score of the FCV-19S was 18.1 (SD = 5.2), and a sizeable proportion of older adults, ranging between 12%-34%, agreed with the seven items of the fear scale. Increasing age, Dalit ethnicity, remoteness to the health facility, and being concerned or overwhelmed with the COVID-19 were associated with greater fear of COVID-19. In contrast, preexisting health conditions were inversely associated with fear. Conclusion Greater fear of the COVID-19 among the older adults in eastern Nepal suggests that during unprecedented times such as the current pandemic, the psychological needs of older adults should be prioritized. Establishing and integrating community-level mental health support as a part of the COVID-19 preparedness and response plan might help to combat COVID-19 fear among them

    Recurrent lower gastrointestinal bleeding from idiopathic ileocolonic varices: a case report

    Get PDF
    <p>Abstract</p> <p>Introduction</p> <p>Varices of the colon are a rare cause of lower gastrointestinal bleeding, usually associated with portal hypertension due to liver cirrhosis or other causes of portal venous obstruction. Idiopathic colonic varices are extremely rare. Recognition of this condition is important as idiopathic colonic varices may be a cause of recurrent lower gastrointestinal bleeding.</p> <p>Case presentation</p> <p>We report the case of a 21-year-old Asian man from north India who presented with recurrent episodes of lower gastrointestinal bleeding. Colonoscopy revealed varices involving the terminal ileum and colon to the sigmoid. Thorough evaluation was undertaken to rule out any underlying portal hypertension. Our patient underwent subtotal colectomy including resection of involved terminal ileum and an ileorectal anastomosis.</p> <p>Conclusion</p> <p>Colonic varices are an uncommon cause of lower gastrointestinal bleeding. Idiopathic colonic varices are diagnosed after excluding underlying liver disease and portal hypertension. Recognition of this condition is important as prognosis is good in the absence of liver disease and is curable by resection of the involved bowel.</p

    "The fruits of independence": Satyajit Ray, Indian nationhood and the spectre of empire

    Get PDF
    Challenging the longstanding consensus that Satyajit Ray's work is largely free of ideological concerns and notable only for its humanistic richness, this article shows with reference to representations of British colonialism and Indian nationhood that Ray's films and stories are marked deeply and consistently by a distinctively Bengali variety of liberalism. Drawn from an ongoing biographical project, it commences with an overview of the nationalist milieu in which Ray grew up and emphasizes the preoccupation with colonialism and nationalism that marked his earliest unfilmed scripts. It then shows with case studies of Kanchanjangha (1962), Charulata (1964), First Class Kamra (First-Class Compartment, 1981), Pratidwandi (The Adversary, 1970), Shatranj ke Khilari (The Chess Players, 1977), Agantuk (The Stranger, 1991) and Robertsoner Ruby (Robertson's Ruby, 1992) how Ray's mature work continued to combine a strongly anti-colonial viewpoint with a shifting perspective on Indian nationhood and an unequivocal commitment to cultural cosmopolitanism. Analysing how Ray articulated his ideological positions through the quintessentially liberal device of complexly staged debates that were apparently free, but in fact closed by the scenarist/director on ideologically specific notes, this article concludes that Ray's reputation as an all-forgiving, ‘everybody-has-his-reasons’ humanist is based on simplistic or even tendentious readings of his work

    The Anxiety of Freedom

    The enduring appeal of liberalism lies in its commitment to the idea that human beings have a "natural" potential to live as free and equal individuals. The realization of this potential, however, is not a matter of nature, but requires that people be molded by a complex constellation of political and educational institutions. In this eloquent and provocative book, Uday Singh Mehta investigates in the major writings of John Locke the implications of this tension between individuals and the institutions that mold them. The process of molding, he demonstrates, involves an external conformity and an internal self-restraint that severely limit the scope of individuality.Mehta explores the centrality of the human imagination in Locke’s thought, focusing on his obsession with the potential dangers of the cognitive realm. Underlying Locke’s fears regarding the excesses of the imagination is a political anxiety concerning how to limit their potential effects. In light of Locke’s views on education, Mehta concludes that the promise of liberation at the heart of liberalism is vitiated by its constraints on cognitive and political freedom

    Comparison of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) for treatment of renal stone size between 1.0 cm to 2.5 cm: a prospective study

    Objectives: To evaluate the efficacy and safety of RIRS and PCNL in treatment of renal stone size between 1-2.5cm. Methods: This comparative prospective study was conducted in the Department of Urology of a tertiary care teaching hospital of Rajasthan from January 2019 to June 2020. Patients were fully informed about the study protocol and a written informed consent has obtained from patients with renal stone disease without any co-morbid conditions, posted for RIRS and PCNL. Stone free rate, post operative complications, hospital stay, operation time and cost between RIRS and PCNL for treatment of renal stone size between 1-2.5cm were compared. Results:&nbsp; Out of total 313 patients, 212 patients underwent PCNL and 101 patients RIRS. The stone clearance rate was significantly better in PCNL (92.45%) than RIRS (85.15%). The hospital stay was significantly less in RIRS (2.02±1.36 days) when compared to PCNL (3.89±2.18 days). Mean operative time for PCNL was significantly less i.e. 71.81±12.89 minutes as compared to 85.79±13.94 minutes in RIRS. Post-operative complications were more in PCNL group than RIRS. Conclusions: This study concluded that PCNL when compared to RIRS both have advantages and disadvantages according to size and location of stone, post-operative complications, stone free rate and operation cost. Judicious use of PCNL and RIRS should be done according to above mentioned parameters
