A higher cetane number means that the fuel has better ignition quality than fuels with lower cetane numbers. Cetane number is a measure of a fuel’s ignition delay, which is the time period between the start of … Read more

With the growing focus today on noise-control issues and the emergence of sound quality as an important aspect of product design, acoustic material testing is becoming increasingly relevant to researchers, engineers, designers and manufactures from a broad range of industries. Products like bio-composites, fibre-reinforced plastics, felt and insulators are being used as sound dampening components, … Read more

Mycorrhizas are symbiotic associations that are formed between the roots of most plant species and soil fungi (Bagyaraj, 1984). Benefits of arbuscular mycorrhiza (AM) associations include improved nutrient uptake by fungi, extending their hyphae through the plant roots into the surrounding soil and transporting the nutrients directly into the plant.
