  • Analysis of a Externally Modified Combustion Engine to Operate with a
           Immiscible Fuel of 80% Gasoline and 20% Water

    • Abstract: Analysis of a Externally Modified Combustion Engine to Operate with a Immiscible Fuel of 80% Gasoline and 20% Water
      Pages 7-10
      Author Melchor Llosa DemartiniJuan Carlos Cuba Solan
      In this paper, we present the results of the analysis of a combustion engine modified to operate with an immiscible fuel that has a ratio of 80% water and 20% gasoline. The project consisted also in redesigning the intake and exhaust system circuits of the engine and we observed that there was a substantial change in the composition of exhaust gases, finding that this change was an environment friendly solution to vehicle pollution.

  • Conservation and Management of Wetlands in Pandihing Bird Sanctuary of
           Sibsagar District, Assam

    • Abstract: Conservation and Management of Wetlands in Pandihing Bird Sanctuary of Sibsagar District, Assam
      Pages 1-6
      Author Shukla AcharjeeNitashree Mil
      Wetlands are the most common and integral feature of the fluvial landscape of Assam. The wetlands are locally known as “Beel”, “Jolah”, “Pitoni” etc. The beels in Assam are water bodies of different size and shapes, generally connected to the rivers the Brahmaputra, Barak and their tributaries. Panidihing Bird Sanctuary of Sibsagar district is very rich in wetland ecosystem. The wetlands play a vital role in the creation of good ecosystem balance and in maintaining healthy environmental condition of the area. In spite of their well recognized importance, the wetlands of Panidihing area presently suffer from degeneration and ecodegradation. These wetlands at present, however constitute a fast disappearing habitat in the Panidihing area. In this paper, an attempt is made to highlight the severity of the wetlands as sanctuary and provides a framework for the better management of the sanctuary.

  • Influence of Hard Water Ions on the Growth of Salmonella in Poultry
           Processing Water

    • Abstract: Influence of Hard Water Ions on the Growth of Salmonella in Poultry Processing Water
      Pages 16-20
      Author Ronald Holse
      The influence of magnesium and calcium ions in process water on the growth of Salmonella was evaluated and related to the contamination in process wastewater. Salmonella typhimurium was grown in the laboratory and exposed to 500 mg/kg and 1000 mg/kg of magnesium and calcium ions to simulate hard process water. Growth curves exhibited a lag time that measured the inhibitory influence of these ions. Results were compared to the application of trisodium phosphate solutions commonly used as a disinfectant. Exposure to hard water ions showed antimicrobial activity toward S. typhimurium comparable to treatment with 5% trisodium phosphate. This is significant to poultry washing and chilling operations where process water directly contacts poultry carcasses and becomes contaminated with pathogenic bacteria transferred into process wastewater.

  • Estimation and Analysis of Carbon Emissions in Hubei Province Based on
           Energy Consumption

    • Abstract: Estimation and Analysis of Carbon Emissions in Hubei Province Based on Energy Consumption
      Pages 11-15
      Author Yanping HouYinrong Che
      Hubei Province is at its 12th-Five Year Plan development stage with accelerating urbanization and new industrialization, which is surely driving the increase of energy consumption. Therefore, it is extremely important, in the broad background of calling for low carbon development from the world wide, that economic development is achieved and carbon emissions is reduced at the same time. This study was aimed to learn about the current situation of carbon emission from energy consumption in Hubei Province, China and give suggestions on related policies. In this study, industrial space was first classified into 3 groups of agricultural space, living and industrial-commercial space and transportation industrial space. Then, carbon emission from energy consumption was estimated using the method I of IPCC. The results showed that living and industrial-commercial land use imposed the biggest pressure on the environment in Hubei Province, followed by transportation industrial land use and then agricultural production land use. Although carbon emission from energy consumption is effectively controlled to some extent when economy is developed in Hubei Province, energy dependence has not been changed.
