Canvas Autoquiz

Online learning management platforms such as Canvas are thriving and quickly replacing traditional classrooms, especially during these pandemic-struck times. As more and more quizzes are administered online, we need tools that make the quiz creation process easier and faster. Canvas Autoquiz is a command-line tool that allows instructors to automatically create and upload quizzes of varying difficulty levels. It also allows instructors to export quizzes from one LMS platform to another. This project explores the need, design, and implementation of the tool, and prospective future work

CodEval: Improving Student Success In Programming Assignments

CodEval is a code evaluation tool that integrates with the Canvas Learning Management System to automatically evaluates students' work within a few minutes of the submission. This early feedback allows students to catch and correct problems in their submissions before their submission is graded and gives them a clear idea of the quality of their submission. CodEval handles the tedious aspects of grading, such as compiling and running tests, leaving graders more time to spend on the qualitative aspect of grading. Before using CodEval, instructors would not have a clear view of the student's comprehension of the concept evaluated by the assignment until after the due date. CodeEval helps instructors identify and address the gaps in students' understanding and thus helps more students successfully complete the assignment. We implemented CodEval using Python using the public Canvas API. Any instructor or grader for a Canvas course can use CodEval to automatically evaluate submissions for programming assignments. We developed a syntax to express requirements of submissions such as compilation parameters, inputs, outputs, command-line arguments, timeouts, exit codes, functions used, files generated, output validators, and more. We have made CodEval open source. CodEval is an easy tool for students, graders, and instructors and seamlessly integrates with Canvas. We share our experience with using CodEval in two classes with a total of 90 students and multiple coding assignments

A case report: remdesivir effective in the treatment of severe category COVID-19

Since the first cases were reported in December 2019, infection with the severe acute respiratory corona virus 2 (SARS-CoV-2) has become a worldwide pandemic. COVID-19 the illness caused by SARS-CoV-2 is overwhelming health care systems globally. In the absence of a proven effective therapy, current management consists of supportive care, including invasive and noninvasive oxygen support and off-label or compassionate-use therapies, including   anti-retrovirals, anti-parasitic agents, anti-inflammatory compounds, and convalescent plasma. Amongst these experimental therapies, remdesivir a broad-spectrum antiviral drug has shown some promising results. We present a successfully treated patient of severe acute respiratory illness by SARS-CoV-2 with remdesivir along with standard management protocol. Reporting a case with aim to add favoring evidence for remdesivir in the treatment of         SARS-CoV-2

Multiagent Simulators for Social Networks

Multiagent social network simulations are an avenue that can bridge the communication gap between the public and private platforms in order to develop solutions to a complex array of issues relating to online safety. While there are significant challenges relating to the scale of multiagent simulations, efficient learning from observational and interventional data to accurately model micro and macro-level emergent effects, there are equally promising opportunities not least with the advent of large language models that provide an expressive approximation of user behavior. In this position paper, we review prior art relating to social network simulation, highlighting challenges and opportunities for future work exploring multiagent security using agent-based models of social network

Contrast-Induced Nephropathy: Myth or Reality? Single center experience in patients undergoing planned percutaneous coronary intervention

The definition of Contrast-induced nephropathy (CIN) is the impairment of renal function and is measured either as increase in serum creatinine (SCr) by 25% from baseline or 0.5 mg/dL increase in absolute value, within 48-72 hours of intravenous contrast administration.The objectives were to establish the incidence of CIN and to define the clinical and periprocedural risk factors leading to CIN in patients receiving contrast media.Methods: In a retrospective, observational, descriptive study, patients who were admitted to the hospital for therapeutic Percutaneous Coronary Inervention (PCI) between June 2020 to December 2020, the serum creatinine and glomerular filtration rate (GFR) prior to angiography and 72 hours post procedure were measured. Results: 202 patients were included in the study, of which 4.45 % developed CIN.Discussion: In our study,the incidence was found to be lower than the literature review. The present study investigated renal function in the chronic phase in patients with ischemic heart disease undergoing planned PCI. The progression of renal dysfunction in patients who develop CIN is thought to result from glomerular overfiltration in the residual nephrons and the release of neurohormones that reduce renal blood flow

Retained surgical sponge migrating in hollow viscous presenting with obstructive symptoms: gossypiboma - a surgeon’s misfortune

Gossypiboma, cottonoid or textiloma, are the common terms used for the cotton or woven fabric which is incidentally left behind in a body cavity during surgery. Gossypiboma is a serious complication which is rarely reported because of its medicolegal issues. The cases of retained surgical sponges are most commonly diagnosed intra-abdominally but they can also be diagnosed in the spine, thorax, breast, central nervous system, and extremities. Gossypiboma has a variable presentation, and it is difficult to diagnose. They can lead to an inflammatory reaction, secondary infection or abscess formation in acute cases. A foreign body usually remains asymptomatic for a long duration, and later it may present with intestinal obstruction, mass formation, peritonitis or fistulisation[1]. It has also been reported to migrate transmurally into adjacent hollow viscous. We are reporting two cases of migrating Gossypiboma presenting with obstructive symptoms. The first case is a 56-year-old female patient who was admitted with pain abdomen, with nausea and vomiting. She had a history of open cholecystectomy four months back and was detected to have a retained surgical sponge which had migrated into the stomach transmurally and was diagnosed by imaging and confirmed during surgical exploration. The second case was a 36-year-old female admitted with pain in the abdomen for the past 2 weeks which was associated with vomiting. She had undergone dilatation and curettage following misconception six months back followed by a surgical procedure. The retained surgical sponge was diagnosed in the ileum by imaging and confirmed during exploratory laparotomy

APRAISAL OF DEMOLISHED CONCRETE COARSE AND FINES FOR STABILIZATION OF CLAYEY SOIL

Road pavements or structure on loose soil needs stabilization. Soil stabilization is mainly done for modifying soil engineering properties to improve the bearing capacity and durability property of weak soil. At the same time the waste material disposal is possessing a lot of problem for disposal. The aim of the study is to appraise the waste material with a review on stabilization of clayey soil using demolished concrete structural fines. Various methods are available for stabilizing clayey soil. These methods include stabilization with chemical additives, soil replacement, compaction control, moisture control and thermal methods. Based on literature reviews and use of demolished waste issues, fines obtained from demolished waste is a low cost and effective soil stabilization method. This dissertation presents the results of a study that investigated the use of demolished concrete in the stabilization of expansive clayey soil. The demolished waste is crushed into fines and coarse materials and grading of fines is done to know the properties of demolished fines and there suitability as a stabilization material. The soil has been stabilized with 0.5%, 10% and 25% of demolished concrete fines and coarse. The final mixtures were tested: Moisture Content Atterberglimits, Compactionand California Bearing Ratio Unconfined Triaxial test. Results indicates that demolished concrete content increases, maximum dry density decrease while CBR values tend to increase. Thus, demolished concrete could potentially act similar to lime or cement in improving the properties of clayey soils. Finally it is concluded that the specific gravity increases with increase in amount of stabilizer. Plasticity index of soil decrease with increase in amount of stabilizer. The maximum dry density increases, and the optimum moisture content decreases with increasing the concrete content in the mixture. The CBR values of the mixtures increases with increasing the recycled concrete content in the mixture. Using C&D waste in soil stabilization helps to reduce the hazardous environmental impacts of the waste and improves the engineering properties of soil which ultimately reduces the cost of construction and increases the life of the structure built on stabilized soil
