The effect of wheat straw leachate on growth of oyster mushroom (Pleurotus ostreatus) spawn

By Mashudu R. Masevhe, Nicolette J Taylor, Puffy Soundy

Abstract: Wheat straw (Triticum aestivum – Duzi) is known for its growth inhibitor in both field and in vitro experiments. The roots of lettuce and wheat seedlings were particularly inhibited when incubated with leachate of wheat straw. In South Africa, mushroom industry is the only industry that directly converts straw into a protein source for human consumption. Therefore, the objectives of the study was to assess the potential growth inhibition of …

Exploring the Flow Physics during Unsteady Shock Interactions Using CFD and Numerical Analysis

By Sravankumar Kota, Sameer Ahamed Shaik

Abstract: Numerical reproductions were done to analyze a Shock Interaction component in the twofold wedge design. The first wedge edge is steady in quite a while. Huge contrasts in stream structure were seen between the calculations with different edges on second wedge. The most exceptional violent variances happened toward the edges of the whole area. Symmetric and antisymmetric movements of the detachment district were recognized in the immediate stream utilizing restrictive …

Design and Fabrication of Trammel Balls

By Naresha K, Abhishek G Hegde, Akash Domakunti, Karthik CB, Santrupth K

Abstract: Transportation of water plays a vital role in the survival of a growing population. If the scarcity of water is one major issue, transportation of water using tankers have their own share. Water in a partially filled container, when induced with external energy (motion), generates slosh and surge. Both slosh and surge effects work as a resistive factor during transportation. To eliminate the same, few holes are drilled at pre-desired …

Quantification of some Bioactive components and Antioxidant Activity of Various Uniflora Origin Bee Honey Collected During 2016 from East Libya

By Hawaa S. Elferjani, Nagwa H. S. Ahmida, Mohamed H. Ahmida, Huda M. Alqitani

Abstract: In this study seven honey samples from three different cities of East Libya were collected in order to evaluate their biochemical properties and antioxidant activities. The results show that the proline content ranged from 77.32-222.43mg/kg. The total phenolic and total flavonoid contents ranged from 62.75-156.30mg/100g and from 13.94-78.31mg/100g, respectively. While the carotenoids content ranged from 1.0-7.38mg/kg. The antioxidant activities of Libyan honey samples were also investigated, based on free radical …

Essential of bearing in materials engineering

By Bangshidhar Goswami, S. K. Prasad, B. N. Choudhary, D. Das, A. Dasgupta, S. Prasad, G. S. Sharma, TPK. Gautam, S. P. Singh, Y. P. Rao, V. Sharma

Abstract: Essentials of bearing have been to maintain lubricant film to prevent metal to metal contact and hence local welding of two surfaces. Tribological and mechanical properties have improved by powder metallurgy route of bearing fabrications. Alloyed non-ferrous plane bearings have better friction coefficients than pure metals. Betterment has appeared in babbit/ bronze particulate reinforced composites. Ni addition has improved performances of graphite-lead free tin bronze composite layers on surface of …

A Brief Review on Induction heating

By Rekha Rana

Abstract: Induction heating is the method of heating an electrically conducting material (usually a metal) by electromagnetic induction, through eddy currents generating heat in the object. An induction heater is an electromagnet and an electronic oscillator that passes through the electromagnet through a high-frequency alternating current (AC). The rapidly alternating magnetic field penetrates the artifact, producing the conductor's electrical currents called eddy currents. The eddy currents flow through Joule heating through …
