Rocket Sled

Before we wrote the Theory of Osmosis, I helped a friend build a track grinder for a rocket sled track.   I had been working on the project for about a year when I was needed at the project site near Alamogordo, NM  to get the track grinder building project started.   We were grinding the top ….  Read More

Cell Behavior

We were intrigued by the photos and blowups in John Clancy’s excellent book “The Human Body-Close Up” we browsed through the book from the back and were amazed at the detailed photos of the human body and its various parts. We were surprised when we approached the front of the book to find a blowup ….  Read More

Difference between Diffusion and Osmosis.

Quora digest posed the question “What is the difference between Diffusion and Osmosis?” We reviewed Guyton’s Textbook of Medical Physiology.   He notes three modes for transport of ions and molecules through a cell membrane: diffusion, osmosis, and active transport.    We have previously looked at active transport.     The active transport models were  developed to explain movement ….  Read More

Biological Osmosis

The osmosis experiment demonstrated that water flows uphill through a membrane from the pure water side into the wine. A large pressure applied to the wine stopped the flow of water into the wine.  Later experiments showed that a sugar water solution could replace the wine.  This led to Van’t Hoff’s theory for osmosis that ….  Read More

Vapor Pressure and Osmosis

HTMD Engineering was given the opportunity to design and build a cold storage facility for DeKalb Genetics for their hybrid seed corn.  The industry standard design conditions of 50°F and 50% relative humidity were selected, and we chose to insulate the facility with a closed cell spray on insulation which provided both good thermal insulation ….  Read More

Maple Tree Details

Our previous blogs about trees, “My Tree Leaks”, “Maple Syrup” were based on our theory of osmosis, “Osmosis: The Molecular Theory”, 2013” and measurements from our own sugar maple tree. We tapped the tree by drilling a 2 ½” deep hole through the bark and inserting a 3/8” pipe with a pressure gauge as shown ….  Read More

Seed Storage

Seeds are living organisms.    They breathe and exchange heat and moisture with their environment.   With warm temperatures and enough moisture,  seeds will germinate. At low temperature and dry conditions, seeds will hibernate.   World seed organizations support long term storage facilities.   Stored seeds will be used for recovery from a catastrophe.  The Svalbard Global Seed Vault ….  Read More

My Tree Leaks

My Tree Leaks This year, I discovered that my maple tree leaks.   A wet spot appeared on the sidewalk near the base of the tree.   The weather was below freezing at night and warmer in the day. The tree trunk remained below freezing during the day.   As noted in the maple syrup discussion, we proposed: ….  Read More

Learning by Osmosis

During my college days, it was a well-known “fact” that I could learn by placing a book under my pillow at night. Information from the text would be transferred to my brain by osmosis. It never worked for me.   And, it was terribly uncomfortable with some larger texts. I have had success with sleep time ….  Read More
