Bioleaching involves the use of iron and sulfur oxidizing microorganisms to catalyze the dissolution of valuable metals. In this investigation, lagoon material contains 0.39% Cu, in which the major copper bearing mineral is chalcopyrite associated with other minerals present as minor phase. Leaching experiments were carried out using an adapted strain of Acidithiobacillus ferrooxidans with various parameters such as presence/absence of iron, pH, pulp density and temperature. Base of the medium was 9 K (without ferrous) Bio-dissolution of copper was found to be maximum, i.e., 80.9% with 9 K + (with ferrous) at pH-2.0, 10% pulp-density and 35 o C within an incubation period of 30 days.
This paper describes an analytical method of power generation from Wind energy in a specific location. The specific location is chosen as Bhubaneswar, Odisha, India. This paper also includes wind speed analysis, power and energy calculation, Probability Density function, Rate of return etc. over a period of time and conditions affecting it. The different parameters necessary for wind generation are studied and compared.
Sieving prime numbers is an idle example of linear time algorithm since the first sieve of this kind proposed by Eratosthenes. Afterward many sieving algorithm are proposed such as: Sieve of Sundaram, Sieve of Atkin, Sieve of Sorenson and wheel factorization of prime number. In this paper we have proposed the integration of parallelism with these sieving algorithm. We have proposed MPI_Info object with memoization to avoid redundant steps during prime number processing and adding them into the sieve. Nevertheless this paper also demonstrates the MPI Binding with familiar/popular object oriented programming language such as: C++ and Java. This binding done through the two different tools which includes OpenMPI and MPJ Express.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
