the root endophytic fungus, piriformospora indica, colonizes roots of a large number of plant species including cereals and brasicaceae. there are several reports indicating that p. indica protects roots from different path-ogens. in the present study, rice plants were pre-inoculated with p. indica and were subsequently infected with fusarium proliferatum, as the causal agent of root rot and cr...

Abstract Steam flooding is an effective method to enhance oil recovery in heavy reservoirs. However, the influence factors of steam will affect development reservoir after traditional water flooding. So dynamic prediction needs be performed before scheme implemented. In this study, 3D model was established by numerical simulation software CMG; Combined with operating parameters oilfield, temper...

The aim of the present research work is to investigate the influence of Jatropha biodiesel properties on various characteristics of a direct injection compression ignition engine. The experiments were performed at different engine operating regimes with the injection timing prescribed by the engine manufacturer for diesel fuel. The engine characteristics with Jatropha biodiesel were compared ag...

Submodels are developed for injection, evaporation and wall impingement of a liquid LPG spray. The injection model determines the quality of fuel as two-phase choke flow at the nozzle exit. Wind tunnel experiments show the spray penetration more sensitive to ambient flow velocity than to injection pressure. Most evaporation occurs during choking, while heat transfer from surrounding air has a n...

The purpose of this study was to confirm the dimensional accuracy of a newly developed injection pressing method for resin polymerization by making use of the internal electric resistance of resin to determine the optimal timing for resin injection. A new injection pressing polymerization pot with a built-in system to measure the internal electric resistance of resin was used for resin polymeri...

Abstract The increasing demands for reducing fuel consumption and emissions in contemporary technology solutions lead to the use of more sensors, actuators, control applications. With this engine complexity, feedback design is complex due coupling between inputs combustion parameters. To be able controller systematically, model predictive (MPC) comes scope because its advantages multi-input mul...

Cortical long-term plasticity depends on firing rate, spike timing, and cooperativity among inputs, but how these factors interact during realistic patterns of activity is unknown. Here we monitored plasticity while systematically varying the rate, spike timing, and number of coincident afferents. These experiments demonstrate a novel form of cooperativity operating even when postsynaptic firin...

The efficiency enhancement of argon power cycle engines through theoretical means has been substantiated. However, the escalation in-cylinder temperatures engenders abnormal combustion phenomena, impeding augmentation compression ratios and practical efficiency. This study presents a comprehensive investigation employing experimental simulation techniques, aiming to extend boundaries thermal op...

Large-eddy simulations (LES) coupled with a partially-stirred reactor model and finite-rate chemistry are carried out to investigate the effects of n-heptane injection timing on methanol fueled dual-fuel (DF) combustion. Methanol is premixed air in constant volume chamber (T=1000 K, ρ=14.8 kg/m3) form homogeneous mixture (equivalence ratio ϕm 0.3). Liquid fuel provided from high pressure inject...
