  • Irradiation of food is a safe means for preservation

    Robert Hayes | Published: Sat, Aug 31, 2013

    A cost effective method of killing both E-coli and salmonella bacteria from food in a safe way is available for many foods.  This method is that of exposing the food to large doses of ionizing radiation, in much the same way that medical utensils are sterilized when using this...

  • Particle accelerators serve in medicine and science

    Robert Hayes | Updated: Mon, Aug 26, 2013

    Particle accelerators are used in medicine, research and industry for a variety of applications.  Some can even be used for homeland security in detecting smuggled nuclear materials or for sterilizing medical instruments.  The very microwave ovens found in our kitchens use a very...

  • Environmental radiological contamination

    Robert Hayes | Published: Sun, Aug 18, 2013

    When concentrated forms of radioactivity find themselves in the environment, or any accessible areas to people, this is known as radioactive contamination.  The radioactivity has to have been concentrated before this can really be considered as such because technically all things are...

  • Nuclear energy has a long list of benefits

    Robert Hayes | Published: Sat, Aug 10, 2013

    There are a lot of fears commonly held by people who oppose nuclear energy.  Some feel that a nuclear power plant can explode like a nuclear bomb or that nuclear energy is bad for the environment or perhaps even not safe.  Technically, a nuclear power plant could have a melt down under...

  • Why would anyone consider nuclear power for making electricity?

    Robert Hayes | Updated: Fri, Aug 2, 2013

    The capability for using nuclear technology to make electricity was demonstrated over 60 years ago.  Many people still fear anything with the word nuclear in it and may even think the word nuclear is not too different from being dangerous.  In truth, every atom in the universe has a...

  • Quality assurance and control are important in all commercial activities

    Robert Hayes | Published: Sun, Jul 28, 2013

    The importance of having a product  fully meet all the intended requirements and to have all the expected characteristics is the basis for quality control in any process.  When any product is brought to market, there are a number of steps which have to be followed correctly to result...

  • OK, now that really is rocket science!

    Robert Hayes | Published: Thu, Jul 25, 2013

    That is rocket  science!  The real deal is available not too far away in New Mexico, at New Mexico State University (NMSU) over in Las Cruces.

  • Nursing is an art and a science

    Robert Hayes | Published: Fri, Jul 19, 2013

    Sometimes it’s easy to think that physicians are the primary caregivers at a hospital or maybe even that nursing is not manual labor.  Nursing most certainly is a noble profession, many public surveys demonstrate that nurses are one of the most trustworthy professionals in society. ...

  • Nuclear Science and Engineering is more than nuclear energy

    Robert Hayes | Updated: Mon, Jul 8, 2013

    I believe the most exciting of all the engineering and science disciplines is most certainly that of nuclear.  This would be because nuclear science spans all disciplines from the largest scales of cosmology and the origins of the universe to the smallest of the subatomic particles. ...

  • Petroleum engineering is where the big money is for a bachelors degree

    Robert Hayes | Updated: Tue, Jul 2, 2013

    If you wondering what the highest paying job you can get straight out of college is based only on the degree, it appears that job would be petroleum engineering.  Initial offers for fresh graduates from New Mexico Technical  College in Socorro, NM is above $80,000.00 per year.

  • What it takes to become a chemical engineer

    Robert Hayes | Updated: Wed, Jun 26, 2013

    Why is school important?  How would you answer the question as to whether you would rather design paint or to apply it?  Lord we knows we need painters and God bless them but if I had a choice between only those two, I know which I would prefer.  I would rather be a chemical...

  • If it's not grown, its mined

    Robert Hayes | Updated: Wed, Jun 26, 2013

    I can only think of a single instance where a bumper sticker ever galvanized my outlook on anything.  Years ago  I saw a bumper sticker which read, “If it’s not grown, its mined”.  The truth of that statement resonated with me because I was quickly able to see that all the...

  • Electrical engineers bring good things to light

    Robert Hayes | Updated: Wed, Jul 10, 2013

    Have you ever wondered how computers, radios or televisions work?  Ever wonder how a microwave oven or cell phone tower work?  Perhaps you could live without hair dryers and curling irons but what about your remote control, what would be our attitude if we lost all three?  One of...

  • Mechanical engineers make things move

    Robert Hayes | Updated: Wed, Jul 10, 2013

    If you think engines are cool or that motors are interesting, you may want to consider studying mechanical engineering.  Mechanical engineering is the discipline which designs moving things such as cars, pumps, pulleys and turbines.  There is a lot that one has to know in order to be a...

  • Civil engineers saving lives and improving life

    Robert Hayes | Updated: Wed, Jul 10, 2013

    Civil engineering has sometimes been referred to as the easiest of the engineering disciplines but similarly touted as the practice which has saved more lives than all of history’s physicians combined.  As it is, civil engineers provide us with clean sanitary water to drink and separate...

  • Does the evidence show that there are no nuclear disasters?

    Robert Hayes | Updated: Wed, Jun 26, 2013

    The Fukushima and Three Mile Island nuclear power plant accidents have a number of similarities.  These include western design, releases of radioactivity resulting in no measurable health effects and constrained operation under some form of regulated safety oversight.

  • Fukushima showed no radiation health consequences

    Robert Hayes | Updated: Wed, Jun 26, 2013

      On March 11, 2011, a tsunami over 40 feet high breached a protecting barrier on the coast of Japan causing a nuclear meltdown at the Fukushima nuclear power plant.  This happened as a result of one of the most powerful earthquakes ever recorded.  The tsunami cut off all...
