Carrying Capacity Assessment for Religious Crowd Management - An Application to Sabarimala Mass Gathering Pilgrimage, India

Crowd Management is always a challenging task when people gather in large numbers. Crowd disasters in India, including recurring incidents at religious venues, demands a crowd management system developed on the characteristics of the place, event, and participants. Assessment of carrying capacity is the prime process to design crowd management protocols and regulations. Carrying capacity assessment of religious gathering venues in India is often an overlooked process. The present study assessed the crowd carrying capacity of Sabarimala pilgrimage, Kerala, India. Physical carrying capacity assessment methods used for tourism venues have been applied and contextualised for crowd carrying capacity assessment. Characteristics of the venue, pilgrimage and pilgrims were studied to map the active crowd area and space utilisation zones. The physical carrying capacity was estimated based on the comfortable crowd density and threshold crowd density assessments. The study identified two factors influencing pilgrim movement within the venue viz. service level at the holy step and capacity of the darshan facility. Service level at the holy step is the prime factor that regulates the flow of the pilgrim within the venue including the pilgrim movement for deity darshan and hence the comfortable capacity of the holy step was distinguished as the effective carrying capacity of the venue. Physical carrying capacity at the comfortable crowd density has to be maintained throughout the event to avoid the triggering of crowd crushes. The crowd carrying capacity assessment (CCCA) method applied in this study is a simple process. Considering the crowd density and crowd regulation factors, the CCCA method can be applied to design crowd management protocols of other religious pilgrimage destinations in India

Serum neopterin levels in HIV infected patients with & without tuberculosis.

Background & objective : Three categories of prognostic markers are best documented as having significance in relation to prognosis of HIV infection. These include HIV viral load, CD4 T-cell levels and plasma levels of soluble markers of immune activation. The plasma activation markers, like neopterin, tumor necrosis factor alpha (TNF-α), interleukins etc., are products of cytokine activity and represent immunologic changes throughout the body. There is not much information available on serum neopterin estimation in patients infected with both HIV and tuberculosis (TB), though neopterin levels are known to be elevated in pulmonary TB patients. In this study we attempted to correlate neopterin levels with the presence of tuberculosis in HIV infected and uninfected individuals and studied the changes after antituberculosis treatment. Methods : Serum neopterin concentrations were measured by high performance liquid chromatography (HPLC) in 25 HIV-seropositive (HIV-TB) and 10-seronegative (TB) patients with tuberculosis before, during and at the end of antituberculosis therapy (ATT). S-neo was also measured in 10 HIV-seropositive asymptomatic individuals and 10 healthy controls. The results were correlated with clinical, bacteriological and immunological status. Results : All TB patients regardless of HIV status had elevated s-neo concentrations at diagnosis, which declined gradually during treatment. Patients with HIV/TB with CD4 counts < 200/mm3 had the highest levels at baseline with a steep fall during treatment. The median level at the end of treatment was significantly higher in HIV/TB than in TB patients, despite clinical improvement and bacteriological clearance of Mycobacterium tuberculosis. HIV infected asymptomatic individuals had neopterin levels that were higher than healthy controls but lower than HIV-TB patients. Interpretation & conclusion : Serum neopterin levels are elevated in HIV-positive patients, with the highest levels in those with tuberculosis and CD4 counts < 200/mm3. Though the levels decrease with anti tuberculosis therapy, persistently elevated levels indicate progressive HIV disease and a poor prognosis

Longitudinal Changes of Fixation Location and Stability Within 12 Months in Stargardt Disease: ProgStar Report No. 12

Purpose: To investigate the natural history of Stargardt disease (STGD1) using fixation location and fixation stability. // Design: Multicenter, international, prospective cohort study. // Methods: Fixation testing was performed using the Nidek MP-1 microperimeter as part of the prospective, multicenter, natural history study on the Progression of Stargardt disease (ProgStar). A total of 238 patients with ABCA4-related STGD1 were enrolled at baseline (bilateral enrollment in 86.6%) and underwent repeat testing at months 6 and 12. // Results: Outcome measures included the distance of the preferred retinal locus from the fovea (PRL) and the bivariate contour ellipse area (BCEA). After 12 months of follow-up, the change in the eccentricity of the PRL from the anatomic fovea was −0.0014 degrees (95% confidence interval [CI], −0.27 degrees, 0.27 degrees; P = .99). The deterioration in the stability of fixation as expressed by a larger BCEA encompassing 1 standard deviation of all fixation points was 1.21 degrees squared (deg2) (95% CI, −1.23 deg2, 3.65 deg2; P = .33). Eyes with increases and decreases in PRL eccentricity and/or BCEA values were observed. // Conclusions: Our observations point to the complexity of fixation parameters. The association of increasingly eccentric and unstable fixation with longer disease duration that is typically found in cross-sectional studies may be countered within individual patients by poorly understood processes like neuronal adaptation. Nevertheless, fixation parameters may serve as useful secondary outcome parameters in selected cases and for counseling patients to explain changes to their visual functionality

Parallel Processing with 68HC1 I

Parallel processing involves carrying computation of multiple tasks simultaneously. Ideally parallel processing aims at making completing a task faster; by breaking them into smaller divisions. Approach of parallelism varies, while in this project the idea of cache coherency is chosen for parallelism. The idea is to incorporate cache coherency in making multiple microprocessors/microcontroller working simultaneously. The available microprocessors/microcontroller to be used as the test subject is the 68HC11

Onshore preparedness for hazardous chemical marine vessel accidents: A case study

Hazardous and noxious substances (HNS) are widely transported in marine vessels to reach every part of the world. Bulk transportation of hazardous chemicals is carried out in tank container–carrying cargo ships or in designed vessels. Ensuring the safety of HNS containers during maritime transportation is critically important as the accidental release of any substance may be lethal to the on-board crew and marine environment. A general assumption in maritime accidents in open ocean is that it will not create any danger to the coastal population. The case study discussed in this article throws light on the dangers latent in maritime HNS accidents. An accident involving an HNS-carrying marine vessel in the Arabian Sea near the coast of Yemen became a safety issue to the coastal people of Kasargod District of Kerala, India. The ship carried more than 4000 containers, which were lost to the sea in the accident. Six HNS tank containers were carried by the waves and shored at the populated coast of Kasargod, more than 650 nautical miles east from the accident spot. The unanticipated sighting of tank containers in the coast and the response of the administration to the incident, the hurdles faced by the district administration in handling the case, the need for engaging national agencies and lessons learned from the incident are discussed in the article. This case study has proven that accidents in the open ocean have the potential to put the coastal areas at risk if the on-board cargo contains hazardous chemicals. Littoral nations, especially those close to the international waterlines, must include hazardous chemical spills to their oil spill contingency plans
