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

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

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

Molecular Theory Application to Biology

 We have introduced a molecular model for osmosis and have shown that free molecules exist in liquids and solids.   The number of free molecules is directly related to vapor pressure and the temperature of the substance.   From the osmosis experiment we find that water moves from the pure waterside (higher vapor pressure) through the membrane ….  Read More

Osmosis flow for Vesicles and Cells

I recently learned of the 2013 Nobel Prize for physiology or medicine shared by James Rothman, Randy Schekman and Thomas Sudhof, for their work on improving the understanding of structure and function of cell vesicles.    A vesicle is a small fluid-filled membrane sac that occurs both within and outside of cells.    Problems within these vesicles ….  Read More

Successful Seed Storage

Seed Storage Factors. Many elements affect the viability of stored seeds.   Two principal factors that we can control are seed initial moisture content and temperature of storage.   We further assume that temperature and seed moisture remain constant during storage.  Storage time is defined as the years of storage when 90% of the initial batch of ….  Read More
