What are the main differences between ERH and thermal conduction heating or ISTD?
Thermal Remediation Services Inc. | FAQsBoth technologies use electricity and heat the subsurface; however, they really don't have much in common and are rarely considered to be competing technologies. Fundamentally, the TRS ERH process is simple and highly flexible. ERH is an in situ thermal remediation technology that uses the heat generated by the resistance of the soil matrix to the flow of electrical current to raise subsurface temperatures up to the boiling point of water (212°F or 100°C).
What are the main differences between the TRS ERH Process and ETDSP?
Thermal Remediation Services Inc. | FAQsUnlike ETDSP, the TRS ERH Process does not rely on pumping large volumes of water into the subsurface. The TRS ERH Process relies in part on the addition of a small amount of water that is slowly dripped (e.g. a gallon or two per hour) into the electrode to maintain moisture and conductivity at the soil-electrode interface. The TRS method of water hydration eliminates the potential for developing an artificial hydraulic gradient that could cause lateral or vertical contaminant migration.
What are the main differences between venting systems?
Skutt Kilns Frequently Asked QuestionsWindow ventilation and convection hoods are passive-the warm fumes rise, and hopefully, are diluted or escape. This requires very large volumes of fresh air, which is costly in the winter. Collection hoods with electric fans do a better job of removing fumes, but fumes still enter the room air before they are collected. There is usually still a significant odor. External hoods do not help internal kiln performance.
How are conduction and convection heating different than infrared heating?
Schwank Infrared Heaters :: Radiant Gas-firedBy conduction through solid bodies, such as through a windowpane in your heated house to the (cold) outside. The rate of heat transfer by conduction is proportional to the temperature difference and the conductivity of the material through which the heat travels. Through convection by warming air and moving the warmed air to a cooler area.

What are the main differences between HEROES II and HEROES III?
FAQ'sHEROES III is like HEROES II, however, it has been greatly enhanced and numerous new elements have been added. More monsters and hero types, more town types, bigger battlefield (15x11 hexes as opposed to 11x9 in HEROES II), more spells, 128 artifacts, 28 secondary skills, etc. Each hero will now have a paper-doll artifact equipment screen, so only 1 weapon, 1 shield, 1 armor, etc can now be equipped. This will counterbalance the 'make a single superhero' strategy.
How effective is ERH at uniformly heating the subsurface treatment volume?
Thermal Remediation Services Inc. | FAQsERH is highly effective at uniformly heating the subsurface treatment volume. The professional staff at TRS has demonstrated this uniformity in subsurface heating at over 30 sites nationwide since 1997. Subsurface temperature is monitored at every 5-foot subsurface interval at all of our project sites using thermocouples. Temperature data is automatically logged in our control computer and subsurface temperature profiles are generated routinely.
How does ERH compare to radio frequency (RF) or microwave heating?
Thermal Remediation Services Inc. | FAQsRF energy is very strongly adsorbed by soil moisture, which prevents RF energy from propagating more than a few feet from the antenna. In general, this makes RF heating inefficient, expensive, and very rarely used. RF heating may find a niche in treating bedrock with very low water content, which would allow the RF energy to propagate tens of feet from the antenna.

What are the main differences between a VPS and Dedicated Server?
Web Hosting FAQ Hosting Frequently Asked QuestionsA remote web surfer can not tell a Virtual Private Server (VPS) from a dedicated server. VPS servers provide the highest level of security just like a dedicated server, complete with customizable firewall protection and secure isolated disk space. A VPS, like a dedicated server can have an unlimited number of domain names, or web accounts installed on it.
What are the main differences between Gold/Silver and Crystal?
Pokemon Gold, Silver and Crystal - Frequently Asked Question...Several Pokemon learn new moves by breeding and level up. For example, Eevee learning Baton Pass at Lv36. The in-game trades are different. (Instead of trading a Drowzee for a Machop in Goldenrod, you must trade an Abra) The graphics for several levels (most notably the Ice Cave as well as the Battle Tower) have been redesigned. The Daycare People on Route 34 give you an Odd Egg. It will hatch in to one of the baby Pokemon, with a high chance of it being shiny.
What are the main differences between the three types of battery... ?
Fequently Asked QuestionsThere are three main types of battery in common use today. They are Lead-Acid (including both flooded and sealed), Gel and Absorbed Glass Mat more commonly known as AGM. Flooded or Wet Cells are the most common Lead-Acid battery in use, they are usually not sealed and allow the user to replenish the electrolyte water as it evaporates as a result of the charging cycles. As these batteries are not sealed they will spill the corrosive liquid if tipped over or the case gets damaged.
