The devastation of any natural disaster might get intensified by the unplanned rapid urbanization in the hazard-prone areas. Although natural hazards are inevitable, scientific knowledge and technology can be used to minimize or even control the damage. Geoinformation technology, which includes Geographic Information Systems, Global Positioning System, Satellite Communication, Remote Sensing, and World Wide Web, can be used in natural disaster assessment, prevention, and mitigation. The technology is usually applied in three temporal stages of disaster cycles: before, during, and after. The author discusses the geospatial data needs for various disaster analyses and presents a model to perform the vulnerability assessment in single- or multi-hazard prone areas.

Shahzada; Kornbluth, Kurt The technology for harnessing power and heat from biomass fuels is already available. Electricity generation from biomass fuels currently uses the same basic technology used in power plants that burn solid fossil fuels. However, new technologies are being developed to improve power production efficiency from biomass. The potential also exists for local sources of electricity production from biomass by using small-scale gasification plants or systems involving fermentation of biomass. By factoring in the pollution-related environmental and social costs generated by fossil and nuclear fuels, bioelectricity becomes a competitive energy source. Here a Stirling generator was used to produce electricity of small scale using biogas as a fuel. The study was done in such a manner that one can get an idea of the internal incidents of the generator such as: different temperatures, engine speed, blower speed, engine power, oxygen sensor data etc. Also a PCA (Portable Combustion Analyzer) of BACHARACH brand was used to investigate the amount of CO, CF (Carbon Monoxide content referenced to 0% O2), O2, and CO2 in the exhaust gas and also the temperatures (ambient and stack), and percentage of combustion efficiency and excess air.

Azizul; Hayashi, Shigenori This paper presents an evaluation of the current solid waste management practice in Japan. Because of limited space, the siting and construction of a new solid waste management (SWM) facility is a big challenge in Japan. A SWM facility should be socially accepted as well as environmentally and economically sound. So it is considered to be one of the most serious environmental problems confronting urban areas both in developed and developing countries. From the physical characteristics analysis of solid waste in Japan it is shown that about 68% of the total waste is inorganic which has good recycle value. Now-a-days, about 55% of total paper, 78-83% of metal cans and 22.8% of polyethylene terephthalate (PET) bottles are recycled in Japan. At present 20.3% of total solid waste is land filled, including ash from incineration. Approximately 75% of the gross amount of municipal solid waste that Japan generates annually is incinerated providing an estimated 2.5 million Kilowatts of electricity is generated. The “waste management hierarchy” (minimization, recovery, transformation and disposal) has been adopted by Japan in recent times as the menu for developing solid waste management strategies.

The galvanomagnetic properties such as Hall voltage, Hall mobility and magnetoresistance sensitivity of the prepared films were investigated in terms of annealing temperature. All the measurements were taken at room temperature under the magnetic field from 0.1 T to 1.0 T. It is observed that the magnetoresistance sensitivity increases with the decrease of length to width ratio of the specimen. The magnetoresistance sensitivity of 85% was obtained for the film with the length to width ratio of 0.8, annealed at a temperature of 470oC for 60 min. For further improvement of the sensitivity of the film, indium (In) short-bar electrodes were deposited on InSb film and a maximum sensitivity of 105% was successfully achieved for the length to width ratio of 0.2 and magnetic field of 1.0 T.
