Fragmentation of Charged Binary Clusters
Fragmentation of binary mesoscopic clusters composed of H2O/CH3OH and charged with ions (Na+, K+, Cs+,F^, Cl-, I-) of similar sign are studied by molecular simulation. The fragmentation involves the departure of a cluster containing one or more ions from the parent droplet by a break-down of the …

Computer aided blast fragmentation prediction
… data from the field. Powder factor dependence of fragmentation results is also well described by the model. The effect of discontinuities on rock fragmentation by blasting is also incorporated into the model. Discontinuities which are open and filled with air or soil-like material affect …

The discrete coagulation-fragmentation system
… clusters.We express this discrete coagulation-fragmentation system as an abstract Cauchy problem posed in an appropriate Banach space of sequences. The theory of operator semigroups is then used to establish the existence and uniqueness of solutions. We also investigate properties of the …

Intentional fragmentation for material storage
A novel technique (location-relaxed storage) of mixing products within warehouse storage bins is presented and evaluated. Analyses of warehouse operations, storage space efficiency, error sensitivity, and placement policies are presented and compared to traditional warehousing techniques. The major …

Jet Fragmentation at the LHC
… of non-perturbative functions called Generalized Fragmentation Functions (GFFs) as a step towards these goals. This theoretical framework enables the calculation of a broad set of semi-inclusive jet observables. We explore known observables whose distributions can now be calculated using GFFs, and …

Numerical Simulation of Corium Jet Fragmentation
… fall in the form of a jet into a water pool. The fragmentation of the corium jet is a critical process concerning Fuel-Coolant Interactions (FCI). A steam explosion could occur depending on jet fragmentation and dispersion in the water. A 2-D in-house CFD MATLAB script has been developed by …

Intentional Information Fragmentation in Email Management
… One important problem in PIM is information fragmentation (IF) — the condition of having data in different formats, distributed across multiple locations, manipulated by different applications, and residing in a generally disconnected manner (Tungare, 2007). IF can conflict with the PIM ideal …

Fragmentation and reaction of structural energetic materials
… under various conditions to release energy. Fragmentation and impact induced reaction are not well characterized phenomena in SEMs. The structural energetic systems under consideration here combine aluminum with one or more of the following: nickel, tantalum, tungsten, and/or zirconium. These …

Deciphering Biomass Fragmentation using Millisecond Microreactor Kinetics
… insights of biomass pyrolysis with the focus on fragmentation of cellulose using two novel microreactor systems, a. Quantitative Carbon Detector (QCD) b. Pulse Heated Analysis of Solid Reactions (PHASR). Current research of complex chemical systems, including biomass pyrolysis, requires analysis …

Experimental study on carbon fragmentation for hadrontherapy
… field composition, a detailed knowledge of the fragmentation process is essential in order to guarantee the appropriate treatment accuracy. Currently, the Monte Carlo codes are the most powerful tools able to precisely compute the biological dose to be delivered. However, the accuracy of a Monte …

Studies in ring D fragmentation of estrone
… with the immediate aim of generating fragmentation intermediates suitable for 14-allylation. The approaches were based on cleavage of the 16,17-bond via oxidative cleavage or fragmentation methodology. The oxidative cleavage routes involved the preparation of 3-methoxy-17 …

The Effect of Fragmentation Specification on Blasting Cost
… economical excavation of mineral production and fragmentation, the comminution and fragmentation operations need to be studied and optimized independently, as well as together, to create optimized use of energy and cost-effective operation. When there is a change in drillhole diameter or …

Aneuploidy and DNA fragmentation in morphologically abnormal sperm
… to determine the level of aneuploidy and DNA fragmentation, respectively. These results were also compared to that of sperm from control men (n=9) of proven fertility and normal seminal parameters. Results: Sperm from teratozoospermic men, compared to control men, had higher rates of total …

The influence of caprock on blast fragmentation distribution
… results of this work indicated that the caprock fragmentation and the substrate fragmentation need to be treated separately by blasters and engineers"--Abstract, page iii.</p>
