Cell Transport Models
We have looked at vesicles, cell behavior, and biological osmosis. Basically, living organisms are composed of single or multiple cells. From the “Fundamentals of Medical Physiology”, we know that the cell is the smallest unit of life and cells are the fundamental building block of all living things. Cells take in nutrients to generate energy …. Read More
Honey
Honey is a natural topic for Valentine’s Day. Here, we are discussing natural honey. A sweet viscous liquid produced by honeybees. A hive of honeybees can produce 100 pounds of extra honey annually and contains more than 60,000 bees. Each bee produces a partial spoonful of honey during its three to 5-week lifetime. There are ….

Osmosis History
We recently requested a professional review for our book “Osmosis: The Molecular Theory”. That was again an interesting experience. We have had the opportunity to find reviewers who are incompetent or dishonest. Sometimes it is difficult to spot the difference from a short conversation. So, we will review osmosis history once again. Osmosis was discovered …. 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 ….

Maple Tree Details
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 …. 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
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
Osmosis in living organisms
Osmosis is the mechanism for transferring fluids and nutrients across membranes. It occurs in plants and animals and maintains the proper balance between extracellular and intracellular fluids. Although osmotic pressure is measured in the laboratory and has been referred to as a driving force for osmosis Osmotic pressure only occurs in laboratory experiments and calculations. …. Read More
