    The "Pause" - A Review of Its Significance and Importance to Climate Science

    ----------Introduction--------- A comparison of recent temperature trends in isolation of earlier data, say 1998-present, to long(er)-term temperature trends, say 1970-present, reveals that more recent temperature trends are lower than long-term temperature trends. This has led many, including...

    Climate Sensitivity and What Lewis and Curry 2014 Has to Say About It

    Ah yes, it’s that time again folks. A paper is released, in this case Lewis and Curry 2014, that says climate sensitivity is on the low end of the spectrum and the “skeptic” community starts banging pots and pans claiming the ACC theory is dead. Well, like most things in the field of climate...

    Big Bang Theory Show - Impact on Science/Engineering

    The general perception of science and engineering in our society plays a pivotal role in defining the future of those fields, both in terms of employment, funding and general development. One of the recent major emissaries of science and engineering in pop culture is the TV sitcom, Big Bang...

    Voyager 1 is Officially in Interstellar Space

    Voyager 1 is officially in interstellar space. This is so much more than a neat factoid found on page 6 of tomorrow’s paper; this is a profound accomplishment of humanity. If there is one trait that can be said to define humans, in every period of history and geographic location, it is that we...

    NRC to Focus On Industry Driven, "Commercially Viable" Research

    Although slightly old news for Canadians, I’m unsure of its exposure level outside of Canada and I feel it’s one of the most important stories surrounding the question “Where is Canadian Science Going in the Next 5 Years” and it certainly extends outside the frozen tundra of the North. The...

    Material Selection for Gravity Sewer Piping?

    Hi Everyone, I'm looking to specify a piping material for a 4" underground gravity sewer pipe. The old material was cast iron but it has corroded and we are now looking to replace with HDPE. My only concern is that I know HDPE is rather flexible and I'm worried about little peaks and valleys...

    Buna-N Swelling in Oil

    We've got issues with our oil baffles in a bearing for a hydroelectric units shaft. The baffle is made of Buna-N and after about a year the baffle swells, becomes wavy and, in some cases, shears off at its mounting location. Also, the rubber that has been in-service can be torn by hand. The...

    Estimating Plant Compressor LF/avg cfm

    Hi Everyone, I'm looking into a prescriptive incentive program for compressed air for a utility's demand side management. Non-prescriptive programs use data logging and metering in order to obtain plant average/pk cfm and kW. However, I'm looking into ways of automating this for smaller/single...

    Methods of Estimating Plant Compressed Air Usage?

    Hi Everyone, I'm looking into a prescriptive incentive program for compressed air for a utility's demand side management. Non-prescriptive programs use data logging and metering in order to obtain plant average/pk cfm and kW. However, I'm looking into ways of automating this for smaller/single...

    Requirements to "Isolate" a Branch from Main Line

    Hi Everyone, I'm looking into adding a branch off of the blowdown line of a boiler that would house a pump and other equipment (check valve, gate valves, etc..). The branch would be used to mix the water in the boiler from the front blowoff drain to the back blowoff drain during wet lay up...

    Mixing Chemicals During Wet Lay Up

    The firetubes on our boilers are corroding during wet lay ups and the problem has been tracked to a lack of mixing of the oxygen scavenging chemicals. Currently, site is suppose to go down once a week, test the water and fire up the boiler for a little while to mix, if needed. However, this...
