Hydrates in some crude oils have a smaller tendency to form plugs than in others, and lately this is becoming a focus of research. To study this and the action of hydrate antiagglomerants in general, hydrate surface properties must be known. To help in characterizing the surface properties by simulation, the capillary waves of clathrate hydrate surfaces in vacuum is examined in all unique cryst...

May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of sintered layer during sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in ore sintering. In this study, strengthening granulation using pre-pelletizing expand utilization ratio was proposed. The experiments conventional granulation, si...

BACKGROUND AND OBJECTIVES Ferric citrate hydrate is a novel iron-based phosphate binder being developed for hyperphosphatemia in patients with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A phase 3, multicenter, randomized, double blind, placebo-controlled study investigated the efficacy and safety of ferric citrate hydrate in nondialysis-dependent patients with CKD. Starting in April o...

In recent years, certain anesthetics have been shown to have protective effects against acute inflammation in experimental animals, an observation that may yield new options for adjunctive treatment of acute inflammation. In this study, we investigated the effects of chloral hydrate (CH) on the acute inflammatory response in BALB/c mice using lipopolysaccharide/D-galactosamine (LPS/D-GalN)-indu...

-A stable 8.4/~ hydrate of kaolinite was prepared by exchanging ethylene glycol for water in the 10.8 A intercalate of ethylene glycol in kaolinite. The hydrate of kaolinite was characterized by XRD, FTIR and TGA/DSC. From the TGA data, one can estimate that there is 0.60 water molecule per A12Si20~(OH)4 units. The IR data suggest a similarity of the local environment of the intercalated water ...

Electrical methods offer a potential geophysical approach to determining the sub-bottom distribution of gas hydrate in the deep marine environment. Gas hydrate is essentially nonconductive. Hence, sediments with pore spaces partially filled with hydrate or containing veins filled with hydrate are more resistive than surrounding sediments with pore spaces filled with seawater. To date, attempts ...

Formation of natural gas hydrate is a serious problem in the gas and oil industry because it can plug pipelines and destroy the equipment. This study aimes to evaluate the concentration effect of glycol ethers on their synergism with a commercial kinetic hydrate inhibitor (Luvicap 55W) in sweet natural gas-water systems at a constant temperature of 4 oC and pressure of 95 bar. Hydrate formation...

OBJECTIVE Lumbar puncture (LP) is usually associated with anxiety and apprehension in children and their parents. This study was performed for controlling children's anxiety before and during LP and increasing the success of LP due to relaxation of the child following the use of sedative drugs and to compare the efficacy and side effects of oral midazolam and oral chloral hydrate. METHOD This...
