Rule out means to eliminate as a possibility. For tested to rule out high blood pressure. That is, the pressure. Rule out is commonly abbreviated as R/O in medical charts. In the example above, the doctor's note
What is the structure of a RO membrane?
The membrane consists of a skin about 0.25 microns and a support layer about 100 microns. The skin is the active barrier and primarily allows water to pass through. Two types of RO construction are commonly used: 1. spiral wound ---sheets of membrane sandwiched with mesh spacers are connected and wound around a permeate tube; and 2. hollow fiber.
What does r 0 mean in microbiology?
Gauging Contagious Infections R 0, pronounced “R naught,” is a mathematical term that indicates how contagious an infectious disease is. It’s also referred to as the reproduction number. As an infection is transmitted to new people, it reproduces itself.
What does R/O high blood pressure mean?
Rule out means to eliminate as a possibility. For tested to rule out high blood pressure. That is, the pressure. Rule out is commonly abbreviated as R/O in medical charts. In the example above, the doctor's note say: R/O high blood pressure. It is important to note diagnosed with high blood pressure.
What does RO stands for?
Reverse OsmosisRO stands for Reverse Osmosis. It is a process that helps RO water purifier remove unwanted ions, dissolved solids and TDS from the water. Reverse osmosis is the opposite of osmosis.
What does r/o malignancy mean?
The tumor status following treatment is described by the residual tumor (R) classification: R0, no residual tumor; R1, microscopic residual tumor; R2, macroscopic residual tumor. Residual tumor may be found in the area of primary tumor and its regional lymph nodes and/or at distant sites.
What does r/o fracture mean?
We describe a reverse oblique (RO) pattern in which the distal fragment has a prominent anterior spike that is displaced posterior to the proximal fragment. This pattern presents a challenge during closed manipulation utilizing traditional reduction maneuvers.

What happens if biopsy report is positive?
A “positive” or “involved” margin means there are cancer cells in the margin. This means that it is likely that cancerous cells are still in the body. Lymph nodes. The pathologist will also note whether the cancer has spread to nearby lymph nodes or other organs.

What is reverse osmosis?
Reverse osmosis, a technique pioneered during the last half of the 20th century, is increasingly being used to desalinate sea water, says Rodriguez (water treatment technology, UNESCO-IHE, the Netherlands), but fouling of the system is one of the primary limiting factors to its success.
What is the rate of a high-rejection reverse osmosis membrane?
Modern high-rejection reverse osmosis membranes have the ability to retain both organic and inorganic dissolved contaminants at rates of over 99 percent, but have been limited by fouling and scaling issues.
What is aerobic biological treatment?
The aerobic biological treatment is being operated as an Activated Biological System with surface Aerators, The bio treated water is pumped to pressure sand filter, activa ted carbon filter followed by Reverse osmosis process.
Which has a higher R 0?
Airborne illnesses tend to have a higher R 0 value than those spread through direct contact.
What happens if you have an R 0 of 18?
For example, if a disease has an R 0 of 18, a person who has the disease will transmit it to an average of 18 other people. That replication will continue if no one has been vaccinated against the disease or is already immune to it in their community.
What is RO made of?
The majority of the commercially manufactured RO membranes are made from cellulose acetate, polysulfonate, and polyamide. Many other kinds of membrane made of a single polymer or a copolymer are also available for specific purposes. The membrane consists of a skin about 0.25 microns and a support layer about 100 microns. The skin is the active barrier and primarily allows water to pass through.
What is fouling in RO systems?
A major problem in operating RO systems is concentration polarization or fouling which is the gradual build up of rejected solute on the feed side, immediately adjacent to the membrane. A flush cycle is often used to reduce build up. The spiral wound construction is less susceptible to fouling than that of the hollow fiber unit. A membrane module lasts two to three years on the average. The shut down procedure for non-working hours should assure that minimum flow and operating pressures are continued with a timed internal flush cycle.
What is reverse osmosis?
Reverse osmosis (RO) has been known for more than a century, but it did not become a commercial process until the early sixties when a special membrane was developed (1,2,3,4). Because RO operates at a comparatively low temperature and is relatively energy efficient, it is employed in various applications, e.g., desalination, treatment of waste water, reclamation of minerals, concentration of whey and other food products, and purification of water (5,6). In recent years, RO has been used increasingly in making processed water for dialysis in hospitals and for certain cosmetics and drugs by pharmaceutical manufacturers (7,8). In addition to these applications, RO is capable of producing water of sufficient purity to be used as Water For Injection (WFI) and for the preparation of parenteral solutions (9,10,11,12). This ITG will focus on the chemical and microbiological quality of water produced by reverse osmosis.
How does reverse osmosis work?
Reverse osmosis is a process which uses a membrane under pressure to separate relatively pure water (or other solvent) from a less pure solution. When two aqueous solutions of different concentrations are separated by a semi-permeable membrane, water passes through the membrane in the direction of the more concentrated solution as a result of osmotic pressure (Figure 1). If enough counter pressure is applied to the concentrated solution to overcome the osmotic pressure, the flow of water will be reversed (Figure 2).
What is the active barrier in RO?
The skin is the active barrier and primarily allows water to pass through. Two types of RO construction are commonly used: 1. spiral wound ---sheets of membrane sandwiched with mesh spacers are connected and wound around a permeate tube; and 2. hollow fiber. Either of these modules is assembled into a pressure housing.
Should RO modules be avoided?
The use of filters or ion-exchangers down stream of RO modules should be avoided.
Can bacteria grow in RO water?
It has been reported that bacteria can "grow" through membranes. The mechanism by which bacteria pass through a RO membrane is not known and no correlation exists between a dye leak test of the membrane and its bacterial retention efficiency. Researchers at the Center for Disease Control (CDC) conducted extensive investigations on the bacterial contamination of RO systems used in producing purified water for dialysis (15). They reported: 1. certain naturally occurring Gram- negative bacteria can multiply in relatively pure RO water; 2. thorough periodic disinfection of the entire RO system is essential in producing water with acceptable bacterial counts; 3. stagnant water in pipes down stream of the membrane is the major source of bacteria and endotoxin in the product water; and 4. the efficiency of a membrane in rejecting bacteria is better in continuous operation than in intermittent use.
What does R/O stand for in pressure?
