A Brief History of Door Knobs and Door Handles

Many people believe the doorknob has been around forever. This is not the case. As a matter of fact, the doorknob, the door handle, and sometimes even closet handles really are a fairly modern innovation.

Concerning who gets the credit for inventing them isn’t really apparent. These are only some of this information that is referred to as some.

The times without the Door Knob

The foundation of “how-to-keep-the-door-closed” technology goes way back. References for them have can be found in the Bible itself, only read it and you will find references on camel doors and gates. It can be argued that iron or wooden pub, is actually the precursor to the current-day door knobs. However, its primary use would be to lock the doors.

It can be argued that iron or wooden pub, is actually the precursor to the current-day door knobs. However, its primary use would be to lock the doors.

Just to be clear, keys and locks were in existence in the period of time. But locks and keys were chiefly used on chests and not doors. Using locks doors didn’t catch up finally but these were pretty expensive at that moment.  Apart from this, today, doors are not too expensive and sliding barn door rollers (Also known as “เลื่อนบานประตูโรงนา” in the Thai language) are a new variety of doors available in the market.

To open and open doors effectively people came up with the latch-string. The latch string was designed by poorer individuals who, in the moment, cannot afford to buy the pricier locks.

However, as homes got larger, the latch-string and bar technology jut became too large and cumbersome to be practical.

Through the time of the Greeks, the simple wooden finish was used to open and open doors. This may be considered as the first door-closing technology which used simple mechanisms to keep doors closed.

Archaeological studies, nevertheless, cannot obviously prove these were devised by the Greeks, no matter how smart they had been back then.

All that is known about this man is the fact that he had been an African inventor. Was he a servant or even a freed slave? No one really knows. Whether he or she pursued this patent or sold it to somebody else remains unfamiliar and unclear.

An Overview of Reverse osmosis

Reverse osmosis is a filtration system, through which many types of large ions and molecules have been removed from solution through porous membrane-technology filtration.

Pressure is applied to the solution that will be on the one side of the membrane. As a result, the solute particle remains on the part of their porous membrane while the solvent is permitted to pass to the other side.

Porous seams forbid the large ions and molecules while enable the small ions and molecules to pass through its pores.  Heat recovery water tank (Also known as “ถังเก็บน้ำร้อน” in the Thai language) plays a very important role in a filtration system. As heated water in the tank kills all the bacteria contains in water and clean the water for drinking.

Reverse-osmosis versus standard Osmosis

In conventional osmosis, the arc is allowed to feed the membrane, generally from a low solute concentration area to high solute concentration space.

As a consequence of the movement of lubricants, chemical potential balance (osmotic pressure) is attained.

However, in inverse osmosis, the solvent is moved in the top to low solute concentration area by making use of high outward pressure. That is to say, reverse osmosis is the just reverse of ordinary osmosis. Buy a best solar product from http://www.eakaphatenergy.com/index.php?CategoryID=Category-110504153311520.

History of Reverse Osmosis

Reverse-osmosis had been discovered by scientists at the year 1748, however, the techniques weren’t implemented to some field at that moment.

In 1950, it had been first used to desalinate seawater and lasted to get the exact same purpose for years. Later, it had been used by the printing industries.

Afterward, the principle of reverse osmosis was implemented in numerous industries to purify water. Some of them are the treatment of waste water and desalination, minerals reclamation and purification of water.

Today, this technology is widely utilized in filtering water for dialysis in hospitals, cosmetics drugs, and injections.

Applications of Reverse Osmosis

Reverse osmosis has diverse applications in businesses as well as in houses. The most accepted usage of the plants has been drinking tap water purification both in residential and commercial scale.

Portable RO is widely used by households units for individual water extraction both in rural and urban locations.

Waste water and rainwater is also purified using RO systems and used for landscape irrigation and industrial cooling purposes.

Macular Degeneration of the Eye – a Basic Anatomy

Macular degeneration (AMD) of the eye is a growing health problem around the world. According to statistics, it affects approximately nine million Americans older than 40. In Australia, approximately 15 percent of the population over the age of 50 shows signs of the disease, while in Canada, the cases of AMD grow at a rate of 10,000 per year. 

Macular degeneration is a disease of the macula or the structure found at the center of the retina, which is the region of greatest visual acuity. Because it is highly associated with aging, the majority of AMD cases happen to the elderly. To understand this disease better, one must have a background on the eye structures affected by the condition, namely the retina, macula, and fovea. You would also do well to contact nCCRS to find out more about the condition. 

The retina, which is about 0.5 mm thick, is a structure that lines the back of the eye. It retina is responsible for converting light into electrical impulses, which are then sent to the brain by the rods and cones via the optic nerves. 

The macula, which is the main structure that becomes damaged in macular degeneration, is a yellow, oval-shaped spot found at the center of the retina. The area provides the clearest vision. The optic nerve connects to the macula; hence, any damage to the macula can affect the optic nerve and vice versa. 

Found at the center of the macula is the fovea. The fovea, also known as fovea centralis, is rich in cones, or the photoreceptors that are responsible for color vision. 

Macular degeneration of the eye occurs when the retina, macula, or fovea become damaged genetically, physically, or by the natural process of aging resulting in macular degeneration.

What’s Laser Optics? Find out about Disadvantages and its Advantage
