Numerical simulation of combustion and unburnt products in dual-fuel compression-ignition engines with multiple injection
… lean mixture of natural gas is ignited by direct injection of diesel fuel in a model of the heavy-duty CAT3401 diesel engine. Dual-fuel combustion of natural gas-diesel (NGD) may provide a wider range of reactivity control than other dual-fuel combustion strategies such as gasoline-diesel dual …

Mixing and Combustion Studies in an Optically-Accessible Small-Bore High-Speed Direct -Injection Diesel Engine
… diesel engine equipped with a Bosch common-rail injection system was used to study the effects of injection strategies on mixing and combustion. A single main and multiple injection strategy were investigated in this study, varying injection pressures and first injection timings and quantities. …

Isothermal Titration Calorimetry Uncovers Substrate Promiscuity of Bicupin Oxalate Oxidase
… products are unknown. In this work, we apply the multiple injection method of ITC to characterize the catalytic properties of oxalate oxidase. Steady-state kinetic constants using oxalate as the substrate determined by multiple injection ITC are comparable to those obtained by the horseradish …

Impact of Design Parameters on Detached-Die Tapered Resin Injection Pultrusion
<p>Injection pultrusion is an efficient process for manufacturing composites of continuous lengths with constant cross-section area. The main objective of this study is to compare the performances of the detached-die with the attached-die resin injection chamber configurations. In this work the …

The origin and tectonic significance of the mafic-ultramafic association in the central Virginia Blue Ridge post-Grenville cover sequence
… indicate that these bodies were derived from multiple injection of a fractionating basaltic magma. The characteristics of the Catfish, Flat Creek, and Schuyler complexes confirm that the mafic-ultramafic association is an intrusive sequence rocks intimately related to the Late Proterozoic …

Surrogate Reservoir Model for Generating Pressure, Saturation and Compositional Characteristics at the Grid-Block Level; SACROC field, Scurry County, Texas
… concept will be proven by building a GSRM of CO2 injection--EOR numerical model of SACROC field, Scurry County, Texas. The SACROC model (CMG GEM) in use was previously generated and history matched by the Petroleum Engineering & Analytics Research Lab - PEARL - at West Virginia University, it is …

Improved statistical quantitation of dynamic PET scans
… may be recovered from dynamic PET scanning with multiple time frames. Assuming a tracer’s interaction with the tissue is linear and time-invariant, the tissue time course can be expressed as a convolution between arterial input function (AIF) and the tissue impulse response/residue function. …

Multihole injectors for direct-injection gasoline engines
… technology, are believed to be promising Fuel Injection Equipment (FIE) for Direct-Injection (DI) Spark Ignition (SI) gasoline engines. Having explored thoroughly swirl pressure atomisers and their spray behaviour, multi-hole nozzles represent the second-generation injectors. Thus, complete …

EFFECTS OF HYPERTONIC SALINE ON RECOVERY OF FUNCTION FOLLOWING CONTROLLED CORTICAL IMPACT BRAIN INJURY
… that future research into HS should include drug injection time course studies. Multiple injections may be responsible for the notable tissue damage. Therefore, it is possible that fewer injections will result in comparable behavioral recovery and less tissue damage that was observed. Due to the …

Novel Ignition Approaches for Improved Hydrogen Ignition
The first study examined H₂ double injection ignition with varying dwell times. Experiments utilized a constant-volume combustion chamber (CVCC) with optical access, replicating compression-ignition engine conditions. Baseline environment: 23.8kg/m³ gas density, 21vol.% O₂, 1000K core temperature. …
