Salt concentration and species affects protein extractability and processed meat characteristics
… the Institute of Medicine has recommended that salt levels be reduced in food, including processed meats. As such, it is critical to understand the interaction of salt level and meat species with regards to characteristics of further processed meat. Salt-soluble protein extraction, important in …

The effect of soluble salt concentration and two organic media on the growth and quality of Brassaia actinophylla and Dieffenbachia maculata "Lodd" G. Don
… grown in two organic media and treated with five salt solutions to determine the effect of soluble salt concentration on growth and quality. The soluble salt concentration was determined using the saturated paste extract method. Dieffenbachia growth and quality were better when 0.45 g/l 15-30-15 …

Simulation of Weak Polyelectrolyte Brushes
… brushes (PABs) was examined with respect to pH, salt concentration, monomer sequence and grafting density. While PEBs have only acidic or basic monomers, PABs contain both types of monomers, resulting in more complex interactions that require advanced simulation methods to properly investigate. …

A central composite design to investigate antibody fragment production by Pichia pastoris
… between growth parameters (agitation, glycerol concentration, salt concentration) and responses (biomass, growth rate, protein expression), by a 3-factor-3-level central composite factorial design. This experimental design involved running shake flask culture at 15 different experimental …

The use of numerical groundwater model to improve effectiveness of subsurface drainage system in irrigated field
… subsurface<br/>drainage systems for controlling salt concentration in the root zone on salt affected<br/>irrigated land. The SEAWAT model was used to optimize subsurface drainage design to<br/>ensure that the salt concentration of the groundwater at the base of the root zone does not<br/>exceed …

Flow-Induced Self Assembly in Micellar Fluids with Applications to Nanomanufacturing
… how they are influenced by the presence of added salt First, we study the effect of salt concentration on the shear rheology of ionic surfactant solutions in simple shear flow. It is shown that for a given surfactant concentration, low salt concentrations induce shear-thickening behavior, while …

DNA structural selectivity of binding by the Pol I DNA polymerases from Escherichia coli and Thermus aquaticus
… is similar when examined across a wide range of salt concentration, but can differ significantly at any individual salt concentration. For both proteins, binding of ss-DNA shifts from weakest to tightest binding of the three structures as the salt concentration increases. Both Klenow and Klentaq …

Flow and transport in wetland deposits
… was sensitive to increases in pore water salt concentration, and to the flushing out of salts from wetland specimens. Finally, it was observed that, for the most part, large changes in hydraulic conductivity did not correspond to changes in the specimen's effective pore size or pore …

Development of Predictive Modeling for the Reduction of Escherichia Coli During the Curing Time of American Type Cheese
… (5.0 to 5.6), curing temperature (4 to 13°C) and salt concentration (0.8 to 1.7%) on survival of E. coli during cheese storage. Fourteen batches of cheese were made and a total of 56 survivor curves representing different combinations of the four environmental parameters were generated during the …

The molecular characterisation of pregnancy-associated plasma protein-A (PAPP-A).
… Western blotting immunodetection at a high salt concentration (0.6M NaCl). At this salt concentration a single band of 195 kDa was immunodetected and this corresponded to the monomeric PAPP-A molecule. It was also discovered that a subset of paratopes in this antiserum reacted, under the …

Colloidal phoretic motion
… to the transport of particles up or down the concentration gradient of a different solute and can be exploited to control particle motion. This thesis seeks to understand the relative importance of different phoretic effects. It examines phoretic motion in the context of concentration …

Carbon-based electric double layer capacitors for water desalination
In capacitive deionization (CDI), salt water is passed through two polarized electrodes, whereby salt is adsorbed onto the electrode surface and removed from the water stream. This approach has received renewed interest for water desalination due to the development of new high-surface area, …

Ultralow interfacial tensions and microemulsion formation in oil-water-surfactant systems
… can pass through a minimum value with respect to salt concentration, temperature and alkane chain length. Surfactant transfer between phases, and phase inversion of macroemulsions are shown to occur around the condition which produces minimum Yc.The origin of the low tensions is thought to be due …

Phosphate, Calcium, and Fluoride Ion Release From Polyurethane Based Microcapsules Formulated in a Resin Based Dental Varnish
… of the microcapsules, the identity of the salt, initial salt concentration in the microcapsules and w/w% loading of the microcapsules in the varnish. It was found that 1,4-butanediol based microcapsules released at a greater rate that the ethylene glycol based microcapsules. The phosphate …

Fractal structure of aggregates induced by shear motion.
… experiments with latex microspheres in salt solutions were conducted to test predictions of the steady-state model and to study the effects of salt concentration and shear rates on the fractal structure of aggregates in both laminar shear and turbulent shear devices. The prediction of …

Rhodium-zeolite hydroformylation of propylene
… conditions. Rhodium form, pH, temperature, and salt concentration altered catalyst behavior. Only RhCl₃•3H₂O preparations on NaY zeolite produced above 80ºC, a pH above 4, and a salt concentration of 0.1N NaCl were required in order to produce an active hydroformylation catalyst. Ammine …

Tracer studies of inlet baffle performance in a horizontal rectangular settling tank model
… performance from input-output relationships of salt concentration. The statistical approach appeared to give much more meaningful information than did the "qualitative" or "conventional" parameters. The pulse testing techniques appeared to give more detailed information regarding the hydraulic …

Development of a Predictive and Mechanistic Model for Capacitive Deionization
… size and the subsequent impact on potential and concentration profiles. This GCS-CS model with pore geometry was applied to six model activated carbons (MACs) of uniform pore size to analyze the effect of influent salt concentration, pore size and geometry, and applied voltage on ion removal. The …
