Surge in number of the Portuguese man-of-war (Physalia physalis) washed up on Juhu and Girgaum beaches, Mumbai, Maharashtra

After the onset of South-west monsoon along the west coast of India, swarming of blue bottle jelly fish the Portuguese man-of-war (Physalia physalis) is observed at Juhu and Girgaum beaches, Mumbai almost every year. Portuguese man-of-war, though often mistaken as a jellyfish, is a marine Cnidarian of the family Physalidae. Its venomous tentacles can deliver painful sting. In July, 2013 sudden strong winds and high tide had brought in several bluebottle jelly fish (Fig 1). For several people, a walk by the seaside at Juhu and Girgaum beaches during first week of July, 2013 ended in redness of skin, swelling, irritation, itching, blisters and severe body ache. The daily news papers carried news items on the marine venomous creature, Portuguese man-of-war and their venomous sting threat to public

Improvements in short-term forecasting of geomagnetic activity

We have improved our space weather forecasting algorithms to now predict Dst and AE in addition to Kp for up to 6 h of forecast times. These predictions can be accessed in real time at http://mms.rice. edu/realtime/forecast.html. In addition, in the event of an ongoing or imminent activity, e-mail “alerts” based on key discriminator levels have been going out to our subscribers since October 2003. The neural network–based algorithms utilize ACE data to generate full 1, 3, and 6 h ahead predictions of these indices from the Boyle index, an empirical approximation that estimates the Earth’s polar cap potential using solar wind parameters. Our models yield correlation coefficients of over 0.88, 0.86, and 0.83 for 1 h predictions of Kp, Dst, and AE, respectively, and 0.86, 0.84, and 0.80 when predicting the same but 3 h ahead. Our 6 h ahead predictions, however, have slightly higher uncertainties. Furthermore, the paper also tests other solar wind functions—the Newell driver, the Borovsky control function, and adding solar wind pressure term to the Boyle index—for their ability to predict geomagnetic activity

Validating the Rice neural network and the Wing Kp real-time models

The Rice neural network models of Kp have been running in real time at http://mms.rice.edu/realtime/forecast.html since October 2007; Dst and AE models were added to our operations in May 2010. All these models use the Boyle index as basis functions computed from ACE real time inputs. Later, two more driving functions were included in November 2012: (a) the “Ram” functions that had dynamic pressure term added to the Boyle index and (b) the Newell functions. The Wing models are a set of neural network-based Kp forecast models adopted by NOAA/Space Weather Prediction Center in March 2011 to supersede the Costello Kp model. This study indicates that any of the three Rice neural net predictors had a better success rate than the Wing model in predicting Kp (r=0.828 with Boyle, r=0.843 with Ram, and r=0.820 with Newell for 1 h predictions; similarly, r=0.739, 0.769, and 0.755 for 3 h predictions) in real time. In a head-to-head challenge using harvested real-time outputs between April 2011 and February 2013, the Rice Boyle Kp models predicted better than the Wing models (0.771 versus 0.714 for 1 h predictions and 0.770 versus 0.744 for 3 h predictions). In addition, Wing’s prediction was missing more often than the Rice prediction (≈6% versus 4.6%), meaning it had less reliability. The Rice models also predict AE (r=0.811 with Boyle; 0.806 with Ram; 0.765 with Newell, and 0.743 with Boyle; 0.747 with Ram for 1 h and 3 h predictions) and pressure-corrected Dst (r=0.790; 0.767, and 0.704, and r=0.795; 0.797 and 0.707 for 1 h and 3 h predictions)

Exfoliative diseases of the integument and mucous membrane that mimic deep 2nd-degree burns with or without sepsis

Introduction: Exfoliative skin diseases in children can mimic burns in many ways and require early diagnosis and management. Here we enumerate the different skin conditions with four case based examples and their management. Clinical Presentation: Varying degrees of skin involvement may be seen with severe involvement in DRESS syndrome and milder involvement in Stevens-Johnson syndrome. Management: The management of this exfoliative lesion is the application of collagen membrane to the wound as we treat burns. Although systemic symptoms can produce mortality (e.g., dress), collagen dressing heals the wound well with good epithelialization. Early and appropriate antibiotic therapy is mandatory. Conclusion: Careful attention to correct diagnosis, early intervention and use of collagen dressing have improved outcome in these children
