The present investigation, involving the simultaneous effects of heat and mass transfer, is concerned with a numerical study of transient free convection MHD flow past an impulsively started semi-infinite vertical plate which is subject to uniform heat flux and diffusion of a chemically reactive
Among his topics are the first and second laws of thermodynamics, entropy generation or exergy destruction, single-phase and multi-phase systems, chemically reactive
systems, solar power, refrigeration, and irreversible thermodynamics.
When UV rays react with atoms or molecules in the air, they produce free radicals (highly chemically reactive
particles) that can break down skin tissue and produce the look of aging.
Last Saturday, HRW released a statement urging Israel to stop its "unlawful" use of the chemically reactive
This spring, crew members on the research vessel Knorr joined scientists from the National Oceanic and Atmospheric Administration to study the impacts of the chemically reactive
industrial particles on cloud formation, ozone destruction, and Arctic warming.
Nasa's Phoenix spacecraft has detected the presence of a chemically reactive
salt in the Martian soil which could make it less friendly to potential life than once believed.
Typical sources of chemically reactive
compounds are the liquids or gases being processed by the machine, the coolant fluids and the lubricant itself.
As these brominated flame retardants are chemically reactive
, explains ICL, they have an advantage over additive flame-retardant types in that they are nonextractable from the foam and avoid the release of bromine compounds into the environment.
So-called "ecologic" or "green" products are not necessarily free from adverse health effects; certain constituents such as terpenoids and linseed oil may be more chemically reactive
than those from nonecologic products.
ROS contain an unpaired number of electrons, which makes them chemically reactive
and extremely toxic to subcellular and cellular structures.
The existence of residual water vapor during deposition is harmful to thin films, since activated or dissociated water molecules are chemically reactive
A free radical is an atom or molecule that has at least one unpaired electron, causing it to be very chemically reactive
To date, API has thermochromatic, coinable, chemically reactive
, pearlescent security and black light sensor inks.
The two most common, chemically reactive
elements in the universe are hydrogen and oxygen.
A hand-held vacuum pump draws an air sample from a seedling into a glass tube where it is mixed with a blue-coloured chemically reactive
substance in a disposable tube.
