One of the major difficulties of explicit parallel programming for a shared memory machine model is detecting the potential for nondeterminacy and identifying its causes. There will often be shared variables in a parallel program, and the tasks comprising the program may need to be synchronized when accessing these variables. This paper discusses this(More)
Present study introduces linseed oil cake as a novel substrate for phytase production by Rhizopus oryzae. Statistical approach was employed to optimize various medium components under solid state fermentation (SSF). An overall 8.41-fold increase in phytase production was achieved at the optimum concentrations (w/w, mannitol, 2.05%; ammonium sulfate, 2.84%(More)
— Shared-memory parallel programs are often designed to be deterministic, both in their final results and intermediate states. However, debugging such programs requires a mechanism for locating race conditions or violations of the intended determinacy when they occur. This paper answers a previously open question by presenting the first precise, efficient(More)
Methods and tools for detecting nondeterminacy in programs for shared-memory multiprocessors are discussed. The approach described divides the debugging chore into two phases. The first phase uses tools that automatically detect nondeterminacy to debug synchronization errors, assuming it is decided at the outset to make the parallel program determinate. At(More)
Fermentation of acid hydrolysate of water-hyacinth (Eichhornia crassipes), a free floating aquatic plant has been investigated for ethanol production. The dilute acid treatment has been applied to utilize the maximum hemicellulosic content of the water-hyacinth. The goal of this work was to investigate, both experimentally and theoretically using(More)
Bioprinting is a rapidly developing technique for biofabrication. Because of its high resolution and the ability to print living cells, bioprinting has been widely used in artificial tissue and organ generation as well as microscale living cell deposition. In this paper, we present a low-cost stereolithography-based bioprinting system that uses visible(More)
Since prehistoric era, plant-derived drugs were much preferred due to their less side effects than drugs of synthetic origin. Bioassay-guided selection of active fraction of a plant extract and further isolation and characterization of the pure bioactive compounds are in practice in both academic and industrial research. Zingiberaceae, a medicinally(More)
Bioethanol is one of the alternatives of the conventional fossil fuel. In present study, effect of different carbon sources on the production of cellulolytic enzyme (CMCase) from Trichoderma reesei at different temperatures, duration and pH were investigated and conditions were optimized. Acid treated Kans grass (Saccharum sponteneum) was subjected to(More)
Neural network and genetic algorithm with altered genetic operators have been implemented into bioprocess field to improve the modelling approach. Enzyme streptokinase is secreted by β-hemolytic streptococcus sp. often used to treat acute myocardial infarction, being a vital drug it is required to be produced in recombinant form for thrombolytic(More)
