Ignition delay times, laminar flame speeds, and mechanism validation for natural gas/hydrogen blends at elevated pressures
(Elsevier, 2013-12-30)New experimental ignition delay time data measured in both a shock tube and in a rapid compression machine were taken to determine the increase in reactivity due to the addition of hydrogen to mixtures of methane and natural ... -
Ignition studies of n-heptane/iso-octane/toluene blends
(Elsevier ScienceDirect, 2016-07-09)Ignition delay times of four ternary blends of n-heptane/iso-octane/toluene, referred to as Toluene Primary Reference Fuels (TPRFs), have been measured in a high-pressure shock tube and in a rapid compression machine. The ... -
Impact of pig slurry amendments on phosphorus, suspended sediment and metal losses in laboratory runoff boxes under simulated rainfall
(Elsevier, 2012)Losses of phosphorus (P) when pig slurry applications to land are followed by a rainfall event or losses from soils with high P contents can contribute to eutrophication of receiving waters. The addition of amendments to ... -
Influence of chemical composition on the fluorescence lifetimes of crude petroleum oils
(Society of Photo-optical Instrumentation Engineers, 2003)Fluorescence based methods are increasingly being used for the analysis of crude oils because they offer high speed, low cost, non-contact, and non-destructive testing options. The fluorescence of crude oils is due to the ... -
The influence of co-formers on the dissolution rates of co-amorphous sulfamerazine/excipient systems
(Elsevier, 2016-03-16)A comprehensive study on the dissolution properties of three co-amorphous sulfamerazine/excipient systems, namely sulfamerazine/deoxycholic acid, sulfamerazine/citric acid and sulfamerazine/sodium taurocholate (SMZ/DA, ... -
