BACKGROUND Urinary sulfate (SO4(2-)) and thiosulfate (S2O3(2-)) can potentially bind with calcium and decrease kidney stone risk. We modeled the effects of these species on the concentration of ionized calcium (iCa) and on supersaturation (SS) of calcium oxalate (CaOx) and calcium phosphate (CaP), and measured their in vitro effects on iCa and the upper limit of stability (ULM) of these salts. ...

The GSR theorem generalizes the classical Rouché theorem of complex analysis, concerning the stability of the total multiplicity of “roots minus poles” for finitely meromorphic functions taking values in the space of Fredholm operators on a Hilbert space. This theorem has been a very useful tool in the stability analysis of nonlinear waves. Proofs based on logarithmic integrals are usually cons...

The Sabine–Neches Waterway (SNWW) is home to the largest commercial port of United States military and refineries that produce 60% nation’s jet fuel. deposited sediments from bank erosion due wake wash result in frequent dredging keep waterway operational. This study investigates vessel-generated waves their impacts on erosion. Surface wave data at Golden Pass City Port Arthur Park dock were me...

Effect of various washing process on the properties of indigo dyed four-way stretch denim fabric was studied in this research. The different washing techniques (Dark washenzymatic treatment, Medium washenzymatic treatment with pumice stone, Bleach washenzymatic treatment with bleaching powder and pumice stone, Acid Wash-Enzymatic treatment with potassium permanganate and pumice stone) were appl...

Reversibility is a mandatory requirement for materials used in heritage conservation, including hydrophobic protectives. Nevertheless, current protectives for stone are not actually reversible as they remain on the surfaces for a long time after their hydrophobicity is lost and can hardly be removed. Ineffective and aged coatings may jeopardise the stone re-treatability and further conservation...

Even under current sea level conditions, many communities are working to protect their coastlines against flooding and shoreline erosion. Coastal often shorelines excessive erosion by using armoring techniques (e.g., bulkheads, riprap). Yet hardened structures reduce of the natural adaptive mechanisms present in coastal ecosystems sustainability system. In contrast, nature-based features living...

Stone Mastic Asphalt (SMA) has been broadly used on heavily trafficked roads and motorways in the UK due to its known stability durability. In this study, several sets of SMA mixtures were prod...
