Biogas is a part of the natural circle. Biogas is formed by the activity of anaerobic bacteria. In nature biogas is produced for example in bogs. It is also possible to produce from biological material in an environment free from air. The gas that is produced is methane (CH4), which is an excellent fuel for heat, electricity, and cars that doesn’t drain the earth’s fossil resources. The raw-material in biogas production has traditionally been waste from the food industries, and communal sewage treatment works....

This paper considers a heuristic technique, known as 3D moving cone to find the optimum pit limit of Sangan iron ore deposit in Iran. To evaluate the results ...

Almost any places in the world, people are using groundwater for drinking and usage needs because of reduced surface and spring waters sources in last decate. Settlement areas, agricultural areas, solid waste areas, industrial areas, waste water discharge areas have always potential to pollute the aquifer media. Boreholes areas for abstracting the ground water has to be picked up not to be carrying risk getting pollution on surface. So it’s necessary for the engineers that hydrogeologic properties has to be choo...

GPS RTK method has never achieved millimetre vertical accuracy. For the most common geodetic tasks such as surveying, staking out and monitoring, GPS RTK method in many cases has been limited by its measuring accuracy. Before the appearance of the new Topcon Lazer ZoneTM technology, we were able to achieve centimetre vertical accuracy (from 1 to 3 centimetre) using GPS RTK systems. Combining Topcon Lazer ZoneTM technology and Topcon GPS RTK HiPer Pro system accuracy of height determination can be increased to a mi...
