Bio-derived rosin acid esters internal electron donors Ziegler-Natta catalyst polypropylene polymerization
2023/12/11
In this contribution, novel bio-derived rosin acid ester compounds have been developed and used as internal electron donors to prepare MgCl2?supported titanium catalysts for propylene polymerization. ...
Mechanical properties of carbon nanotubes/epoxy nanocomposites: Pre-curing, curing temperature, and cooling rate
Carbon nanotubes curing epoxy mechanical properties nanocomposites polymer nanocomposites
2023/11/30
The effects of composite fabrication, such as pre-curing, curing temperature, and cooling rate, were studied. In this work, the pre-curing was defined as heat treatment of Multi-Walled Carbon Nanotube...

A new universal dynamic model to describe eating rate and cumulative intake curves
eating rate food intake cumulative intake curves energy intake satiation differential equation(s) mathematical model Universal Eating Monitor restraint
2018/11/12
Background: Attempts to model cumulative intake curves with quadratic functions have not simultaneously taken gustatory stimulation, satiation, and maximal food intake into account.
Investigating predictors of eating: is resting metabolic rate really the strongest proxy of energy intake?
appetite eating behavior traits energy intake error variance resting metabolic rate
2018/11/20
Background: Evidence suggests that fat-free mass and resting metabolic rate (RMR), but not fat mass, are strong predictors of energy intake (EI). However, body composition and RMR do not explain the e...

Entering the Fast Lane MXene Electrodes Charging Rate Limits Energy Storage
2017/7/24
Can you imagine fully charging your cell phone in just a few seconds? Researchers in Drexel University’s College of Engineering can, and they took a big step toward making it a reality with their rece...
Higher dietary cholesterol and ω-3 fatty acid intakes are associated with a lower success rate of Helicobacter pylori eradication therapy in Japan
Helicobacter pylori dietary factors cholesterol omega 3 fatty acids eradication therapy
2018/11/15
Background:Helicobacter pylori infection is a known risk factor for duodenal ulcers, gastritis, and gastric cancer. The eradication of H. pylori is successful in treating these disorders; however, the...
Associations between iodine intake, thyroid volume, and goiter rate in school-aged Chinese children from areas with high iodine drinking water concentrations
urine iodine concentration, urine iodine excretion, thyroid volume, total goiter rate, children
2018/11/12
Background: Excessive iodine intake may have adverse effects on the thyroid, particularly in children, but the safe upper iodine intake concentration in children is unclear.

ESTIMATION OF THE THICKNESS AND EMULSION RATE OF OIL SPILLED AT SEA USING HYPERSPECTRAL REMOTE SENSING IMAGERY IN THE SWIR DOMAIN
hyperspectral oil spill thickness emulsion rate
2015/9/21
The thickness and the emulsion rate of an oil spill are two key parameters allowing to design a tailored response to an oil discharge. If estimated on per pixel basis at a high spatial resolution, the...
