A Note on the Laminar Heat Transfer in an Annulus

An exact solution for the fluid temperature due to forced convective heat transfer in an annulus is obtained as a solution of the eigen value problem

Antimicrobial Activity of Mollugo cerviana ser. (Molluginaceae)

The ethanolic extracts of aerial shoots of Mollugo cerviana and its leaf derived callus were tested for antimicrobial activity using the filter paper disk assay method. Both the extracts showed antibacterial activity against Bacillus subtilis and Escherichia Coli. The antifungal activity of the extracts against Aspergillus niger and Aspergillus flavus was nil or negligible

Anesthesia Management in an Edentulous Patient with Huge Parotid Tumour: Case Report

Huge head and neck tumors are known to cause difficult ventilation and difficult intubation. Edentulous mouth can result in difficult mask ventilation. Head and neck tumor resections can also present hemodynamic challenge, due to their proximity to large vessels. We herein report a clinical case of difficult ventilation due to large parotid tumor in an edentulous patient

Challenges and opportunities associated with waste management in India

India faces major environmental challenges associated with waste generation and inadequate waste collection, transport, treatment and disposal. Current systems in India cannot cope with the volumes of waste generated by an increasing urban population, and this impacts on the environment and public health. The challenges and barriers are significant, but so are the opportunities. This paper reports on an international seminar on ‘Sustainable solid waste management for cities: opportunities in South Asian Association for Regional Cooperation (SAARC) countries’ organized by the Council of Scientific and Industrial Research-National Environmental Engineering Research Institute and the Royal Society. A priority is to move from reliance on waste dumps that offer no environmental protection, to waste management systems that retain useful resources within the economy. Waste segregation at source and use of specialized waste processing facilities to separate recyclable materials has a key role. Disposal of residual waste after extraction of material resources needs engineered landfill sites and/or investment in waste-to-energy facilities. The potential for energy generation from landfill via methane extraction or thermal treatment is a major opportunity, but a key barrier is the shortage of qualified engineers and environmental professionals with the experience to deliver improved waste management systems in India

Flow of micropolar fluid through a tube with stenosis

mathematical model for the steady flow of non-Newtonian fluid through a stenotic region is presented. The results indicate that the general shape and size of the stenosis together with rheological properties of blood are important in understanding the flow characteristics and the presence of flow separation
