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

Our Amazing Kidneys

We have proposed that osmosis is directly related to vapor pressure and that free vapor molecules exist in liquids and solids.  The quantity of these free molecules is in proportion to the vapor pressure value.   The net flow of free molecules through a porous membrane is the called osmosis.   Flow through porous membranes may also ….  Read More

Cell behavior in hypotonic / hypertonic solutions.

Our efforts to apply the vapor pressure theory of osmosis to medical physiology have been difficult.   The difficulty appears to be due to language differences. Therefore, we’re going to look at a very simple example from a popular medical text.   A cell is placed into pure water.  The osmolality of pure water is much ….  Read More

Me and My Celery

Me and My Celery…… Recently I decided to have a celery snack.  The celery from my refrigerator was not crisp, it was limp.   After finding my “how to do everything in the kitchen” book, I soaked the celery in freshwater overnight.  The next morning it was crisp. WHY does the celery become crisp after soaking ….  Read More
