Municipal solid waste management is a major environmental issue in India. Due to rapid increase in urbanization, industrialization and population, the generation rate of municipal solid waste in Indian cities and towns is also increased. Mismanagement of municipal solid waste can cause adverse environmental impacts, public health risk and other socio-economic problem. This paper presents an overview of current status of solid waste management in India which can help the competent authorities responsible for municipal solid waste management and researchers to prepare more efficient plans.

Life cycle of glaciers in the Himalayan region has notably changed due to the climatic variability since last few decades. Glaciers across the world and specially the Himalayan glaciers have shown large scale degeneration in the last few decades. Himalayan glaciers serve as an important fresh water resource for the downstream communities, who are dependent on this water for domestic and other purposes. Therefore, glacier shrinkage and the associated hydrological changes pose a significant problem for regional-scale water budgets and resource management. These issues necessitate the regular and rigorous monitoring of the wastage pattern of the Himalayan glaciers in field and using satellite remote sensing data. In this work, we report rapid and enhanced degeneration of the frontal part of the Kangriz glacier, Jammu and Kashmir(J & K), in terms of surface melting, debris cover, snout characteristics and meltwater discharge. Ablation data acquired during 2016-2017 shows the average lowering of the frontal part of the glacier to be ~148 ± 34 cm, one-third of which was found to have occurred within a 13 day time period in September, 2017. Also, the quantum of ice melt was found to be inversely influenced(r =-0.84) by the debris thickness. 15 day meltwater discharge measurement revealed its strong relationship with snout disintegration pattern, evidenced twice during the said time period. Volume of water discharged from the glacier was estimated to be 7.91×10~6 m^3 for the measurement duration. Also, mean daily discharge estimated for the 15 days interval showed good positive correction(r = 0.78) with temperature indicating the direct dependency of the former on land surface temperature conditions of the region. Besides the lowering and discharge observations, the frequent ice-block break-offs at the glacier snout further enhance its overall drastic degeneration. The study suggests that, being the largest glacier in the Suru basin, the Kangriz glacier needs to be continuo

Diffusion weighted imaging(DWI) is a method of signal contrast generation based on the differences in Brownian motion. DWI is a method to evaluate the molecular function and micro-architecture of the human body. DWI signal contrast can be quantified by apparent diffusion coefficient maps and it acts as a tool for treatment respon-se evaluation and assessment of disease progression. Ability to detect and quantify the anisotropy of diffusion leads to a new paradigm called diffusion tensor imaging(DTI). DTI is a tool for assessment of the organs with highly organised fibre structure. DWI forms an integral part of modern state-of-art magnetic resonance imaging and is indispensable in neuroimaging and oncology. DWI is a field that has been undergoing rapid technical evolution and its applications are increasing every day. This review article provides insights in to the evolution of DWI as a new imaging paradigm and provides a summary of current role of DWI in various disease processes.

The combination of ipsilateral humeral fractures at three different levels namely proximal, shaft and supracondyle has been rarely defined in the literature. We present a case report on such a complex injury in a 10-year- old child after falling down from the second floor of his house while playing. To the best of our knowledge, no such case report exists in the English literature. We define it as ＂double floating arm＂ injury. Firstly, shaft of humerus was open reduced and fixed with 4.5 mm narrow dynamic com- pression plate. Then closed reduction and pinning of the supracondylar humerus under an image intensifier was obtained. Open reduction using deltopectoral approach to the proximal humerus was done and the fracture was fixed with three K-wires. Ipsilateral multiple fractures in children often result from high energy trauma. Immediate reduction and fixation is required. Usually surgeons need to treat simple fractures firstly, which makes the subsequent treat- ment of complex fractures easier.

Fractures of the radial neck account for 5-10% of traumatic lesions of the elbow in the child. Conservative method of reduction may fail to reduce severely displaced fractures. Open reduction of severely displaced radial neck fractures is associated with a high incidence of complications. The present study describes the results achieved after closed and indirect reduction of the severely displaced radial head using a 2-mm K-wire passed intramedullary from near the radial styloid. The bent tip of the K-wire was used to manipulate the displaced head back to the shaft without opening the fracture site. The indirect reduction of the radial head using bent intramedullary K-wire is a simple, minimally invasive method, easy to perform, and obtains encouraging results with few complications. Intramedullary pin also achieves fixation of the radial head after reduction and prevents its secondary displacement.

Talar body injuries are rare, particularly in children. To our knowledge, there has not been a single case report of bilateral talus fracture in a child till date. We report two cases of fracture bilateral talus in children. The first case is of a fracture separation of the distal tibial epiphysis and a fracture of the body of the talus with subluxation of ankle on right side and a fracture neck of talus on left side. The second is fracture bilateral talus with epiphyseal injury of left distal tibia. A minimal or undisplaced fracture of talus is less likely to undergo avascular necrosis than a displaced fracture but even with optimal treatment, avascular necrosis may still occur. It is of prime significance that these fractures should be diagnosed well in time to avert complications. Therefore an appropriate length of follow-up is required.
