Biological Denitrification Using Saw Dust as the Energy Source

Nitrate contamination is one of the major problems in groundwater, which is increasingly becoming a threat to groundwater supplies. Nitrogen in groundwater also results from human excreta, ground garbage and industrial effluents, particularly from food processing plants. In order to remove nitrate from a water source, such as ground water the biological denitrification technology can be applied...

High-energy Multipass Forward Raman Shifter as an Eye-safe Laser Source for Lidar

A methane Raman cell optimized for generating high energy laser pulses at 1.54 microns wavelength is characterized. 1st Stokes conversion efficiencies up to 43% – equivalent to 62% photon conversion efficiency – were measured. Experimental results show output average power in excess of 17.5 W, pulse energies of 350 mJ at 50Hz, with good beam quality (M < 6.) Narrow bandwidth output is produced ...

Tachyon as a Dark Energy Source

It is demonstrated that dark energy, driven by tachyons, having non-minimal coupling with curvature and self-interacting inverse cubic potential, decays to cold dark matter in the late accelerated universe. It is found that this phenomenon yields a solution to " cosmic coincidence problem ". PACS The idea of tachyons is not new. It was proposed around 40 years back [1] and some cosmological mod...

Molasses as an energy source for cattle.

Molasses has been used as a major energy component of feedlot diets for about 15 years (Preston et al. 1967). Over the last 5 years of drought conditions molasses has been extensively fed to cattle in large areas of north-east Australia applying the principles for its use advocated by Preston and his colleagues (see Preston & Willis 1974). A prerequisite of drought feeding is for low labour cos...
