Towards molecular reconstruction in Coulomb explosion imaging
… the molecular structure prior to a Coulomb explosion of the ionized molecule using only the information available at the detector. There are broadly two components to the approach examined here: the forward and the backward (inverse) problems. In the forward problem, we develop a model using …

Clean Fractionation of Biomass - Steam Explosion and Extraction
… of biomass solids were lost during steam explosion. Cellulose remained almost unaffected (retained in fibers form) by water and alkali extraction. About 35-55 % of the hemicelluloses can be recovered in the water extracted liquor fraction (WEL). The remaining non-cellulosic carbohydrates …

Numerical modelling and observations of nuclear-explosion coda wavefields
… I use numerical modeling of Peaceful Nuclear Explosion (PNE) codas at far regional to teleseismic distances to compare two of such models, namely the conventional frequency-dependent attenuation with parameters (Q₀, η) defined by Qcoda(f) = Q₀f¹ and frequency-independent effective attenuation …

Dissociation dynamics in Coulomb explosion imaging of diatomic molecules
Bei der Coulomb Explosion wird die folieninduzierte Dissoziation isolierter Molekülionen gemessen. Um strukturelle Parameter des Moleküls aus diesen Messungen zu extrahieren müssen Annahmen über die Form des dissoziativen Potentiales gemacht werden. Die Benutzung einfacher Coulomb Potentiale …

Population explosion and poverty amongst Africans in South Africa
… phenomenon has been described as the "population explosion". Why does it constitute a threat? Growth in itself is not necessarily bad; it has been the basis for much human progress in the past. What concerns us is that a large proportion of this growth is concentrated in certain areas of the world …

Torrefaction and Steam Explosion of Selected Biomass for Biofuel Production
… pretreatment processing methods, namely, steam explosion and torrefaction of selected biomass feedstocks (sawdust and oat straw), processing characteristics, and product properties. The study also discusses the economics of densifying biomass, outstanding challenges, the potential for industrial …

The residual strength of a ship after an internal explosion
Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 1988, and (M.S.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 1988.

Modification of Wood Fiber with Thermoplastics by Reactive Steam-Explosion
… of co-refining wood and polyolefin (PO) by steam-explosion was scientifically explored for wood-thermoplastic composites without a coupling agent. Traditional studies have addressed the improvement of adhesion between components of wood thermoplastic composites through the use of coupling agents …

Technical review and economic evaluation: steam- explosion/fractionation of biomass
… the process cost for several scenarios in steam-explosion/fractionation of wood. Steam -explosion pulping may prove to be an alternative to currently practiced standard pulping processes which require large capital investments, cause significant environmental problems, and produce a narrow range …

Steam Explosion Pretreatment of Cotton Gin Waste for Fuel Ethanol Production
… This study focused on the use of steam explosion as the pretreatment method. Steam explosion treatment of biomass has been previously described to increase cellulose accessibility. The governing factors for the effectiveness of steam explosion are steam temperature and retention times. …

Shockless explosion combustion - Controlled autoignition in stratified mixtures for pressure gain combustion
… This type of combustion is termed as shockless explosion combustion (SEC). The main objective of this work is investigate the SEC process experimentally and enable a repeatable and reliable operation which has been realized within the frame of four publications. First, an initial test rig was …
