Abstract:In apparent, the intension is removal of chromium using cow dung as low cost adsorbents from the industrial wastewater. Chromium (Cr) is one of the most toxic substances and is introduced into the environment through a variety of industrial activities. In order to remove the chromium from the contaminated water there are lot of methods available, even though they are not in natural way. In the paper naturally availing material like Cow dung ash is used to remove the chromium by adsorbent method. Since the collected chromium contaminated waste water from the industry will have only a particular Cr+ concentration and pH value, an aqueous solution has been prepared with unique concentration and with different pH values. And activated ash is added separately to the aqueous solution with different dosages and varying contact periods. From the investigation and interpretation of results it has been noted that the Cow dung ash has effectively removed the chromium content when it was added 6g/l to the 1000ml of aqueous solution. In the view of contact time of the adsorbent, 3 hours of period been an ideal one and pH doesn't had a significant effect.

Burns can be devastating and result in unwanted consequences with prolonged length of hospital stay. The mortality rate increases as the total body surface area increases, so proper management of patients with extensive degrees of burns is crucial for their survival. We present the hospital course, management, and survival of a patient after he sustained a 95% total body surface area, second-degree burn from a gas flame. Furthermore, we present from the literature different cases of patients with large total body surface area burns and survived after being managed in burns specialty centers. Although large total body surface area burns can result in significant morbidity and mortality, early management and intervention by an expert surgical team can result in positive outcomes.
