Monitoring of 222Rn/220Rn concentrations at the work places of Muzaffarabad, Azad Kashmir

  Thoron (220Rn), due to its-short half-life of 55.5 s is unable to travel far from its point of generation. A number of studies report indoor radon (222Rn) concentration in different locations of Azad Jammu and Kashmir, while no study reports indoor 220Rn concentration. The CR-39 based passive alpha track detectors were used for the measurement of 222Rn and 220Rn concentrations at different...

Stability of water-in-crude oil emulsions: Effect of cocamide diethanolamine (DEA) and Span83

  Water-in-oil emulsions are important in the petroleum industry in production operations, where the water content of the emulsion can be as high as 60% in volume. An environmentally friendly, nonionic emulsifying agent for crude oil emulsions Cocamide diethanolamine (Cocamide DEA) is introduced in the present work. The emulsion formation, rheology, stability and water separation performance of the...

The influence of adherend width on tensile strength and failure load of Z joints bonded with adhesive

  In this study, the influence of the adherend width on the tensile strength and failure loads of Z joints were analyzed both experimentally and numerically. The Z joints were subjected to tensile load in the experiments. The stress analyses were executed using the finite element method (FEM). The FEM analyses were performed with Ansys (v.14.0.1). The FEM analyses were carried out to investigate the stress and...

Nonlineaer analysis of high-ninlinearity structures

  Rapid progress in the analysis and construction of high-nonlinearity structures has been made over the last three decades. The use of a new method is necessary to accuracy and stability to improve performance of this structure. The Fletcher-Reeves method belongs to a group of methods called conjugate gradient methods which attempt to locate a local minimum function. The approach of the proposed method was...

Climate change mitigation: Challenges of adopting the green energy option in the Lake Victoria basin

  The search for green/renewable energy such as hydropower, wind power, geothermal power, solar electricity and biomass which are environmentally clean is aimed at diversification of the energy matrix, mitigating against climate change and providing alternatives to the use of fossils fuels (coal, oil and natural gas) which are associated with greenhouse gas emissions that cause global warming, environmental...

A life cycle assessment of a coal fired power plant with carbon capture and storage in Mexico

  A life cycle assessment (LCA) was conducted for three cases with the goal of assessing the environmental viability of carbon capture and storage (CCS) as a method of reducing greenhouse gas emissions from the electricity infrastructure in Mexico. Case 1 is standard coal fired power plant, 350 MW and 35.7% efficiency. Case 2 is the same power plant with facilities for carbon dioxide capture using absorption by...
