How do you remove rust off a ball bearing?
You can remove rust from a ball bearing by soaking it in a solution of equal parts white vinegar and water for several hours. After soaking, scrub the ball bearing with a wire brush to remove the rust. Finally, rinse the ball bearing thoroughly with water and dry it completely.

What blood type will the baby have if both parents have different blood types?
The baby will have some combination of the parents blood types. Without more information I cannot give you more specific info.
Basic Concepts for Micro Specimen Collection
1. Universal precaution guidelines must be followed for collection and transport of all specimens. Specimens should be placed in tightly sealed containers; the containers should be free of any external spillage, and the specimens should be transported in bags.
2. Collect the specimen from the actual site of infection, avoiding contamination from adjacent tissues or secretions.
3. Collect the specimen at optimal times (i.e. early morning sputum for AFB culture).
4. Collect a sufficient quantity of material.
5. Use appropriate collection devices: sterile, leak proof specimen containers. Use appropriate transport media. (Anaerobe transport system Amies or Stuart's for bacterial cultures, Cary-Blair for stool culture, M4 for viral and chlamydia cultures.)
6. Whenever possible, collect specimens prior to administration of antibiotics or antivirals.
7. Properly label the specimen including the date, time, and initials of collector. The source of specimen is required.
8. Minimize transport time. Maintain an appropriate environment between collection of specimens and delivery to the Laboratory.
9. If appropriate, decontaminate the skin surface. Use 70-95% alcohol (ALC) and 1-2% tincture of iodine (TIO) or chloroprep containing chlorhexidine gluconate 2% and isopropyl alcohol 70% to prepare the site. Allow a contact time of two minutes to maximize the antiseptic effect.

Can type 0 plus mother and ab plus father have an O plus baby?
No. The child will be either group A or group B, but not group O. This is because the father can donate only a group A gene or a group B gene, so since group A and group B are dominant over group O, the child could not have group O blood.
What is the uses of iron stand with iron ring?
An iron stand with an iron ring is commonly used in chemistry labs to support glassware such as beakers, flasks, and test tubes during experiments. The ring provides a stable platform for heating or suspending the glassware over a Bunsen burner or other heat source. This setup allows for controlled heating and mixing of substances in a safe environment.
What is c-reactive protein test used to diagnose?
It is one of the way to check if there is inflammation in the body. It will tell you if there is inflammation but will not show the cause. This is often used to monitor inflammatory arthritis RA activity.
Have rh- and received rh plus what will happen?
If you are given incompatible blood a series of events occurs that is known as a hemolytic transfusion reaction. It can be extremely serious and may lead to death. The naturally occurring antibodies in the recipient will bind to the antigens on the incompatible donor red cells leading to the breakdown of those cells aka in vivo hemolysis. The liver will then have to try to dispose of the broken down cells resulting in an increase of bilirubin and urobilinogen in the blood and spilling over into the urine. The pateint's blood pressure will start to drop resulting in tachycardia and possibly cardiac arrest...
STAT in medical terms means "right away", or "immediate". A CBC is a "complete blood count". Your doctor may order a STAT CBC for you if he suspects an anemia or other issue that he wants to treat right away.
Why is it acceptable that translation and transcription errors are not corrected?
Translation and transcription errors are often left uncorrected because it is time-consuming and costly to identify and fix mistakes, especially in large volumes of text. Additionally, some errors may be deemed minor and not significantly impact the overall understanding of the content. Prioritizing corrections based on the importance of the information and the resources available is common practice.
What would a glass test tube cost?
That depends on the size, the type of glass, and if the test tube has an special features - such as threading at the top to allow a screw cap to be screwed on...
With that said, a typical price for the test tubes you usually see is around $1/each for a 14 ml Pyrex test tube. I've seen really cheap ones for less than half that when bought in bulk and some specialty ones that were over $5/each.
What are the components of plasma?
Plasma is primarily composed of water, electrolytes (e.g., sodium, potassium, calcium), proteins (e.g., albumin, globulins), clotting factors, hormones, and waste products (e.g., urea, creatinine). It also contains gases, nutrients, and antibodies.
Who was first person to die of radiation poisoning?
Certainly Eben McBurney Byers (April 12, 1880 -- March 31, 1932) has died from radiation poisoning a while before Litvinenko, and even before Marie Curie. It's not clear, however, if he was the first.
What are the pros and cons of using DNA testing in genealogy?
Genetic testing is the best way to discover family relationships. The DNA evidence has a very low error rate and can be used when no other forms of documentation can be found. DNA testing can also link people over a very big span of time. This happened with a prehistoric remains called "Chedder Man" a caveman found preserved in England. DNA testing revealed that one of his relatives still lived in the area he was found in.
On the con side, DNA cannot really give you any other information about the person. Genealogists also want to know details about the person such as their job, friends and how they lived. Recent studies have shown that about one in ten children have incorrect paternity, meaning that the person that they think is their father isn't actually their father. So DNA evidence can also cause problems for families if it turns out that someone may have been adopted or a spouse has been unfaithful.
Is diffusion a form of passive transport?
when diffusion occurs it is because the substance is trying to reach equilibrium, where everything is equally spread out on both sides of a cell membrane. things naturally want to be at equilibrium in nature so this happens automatically and doesn't require any energy. and that is the definition of passive transport transportation of a substance through a cell membrane that doesn't require any energy.
Having a high basophil count can mean various things from minor to fatal. Some of the conditions you may have include Crohn's Disease, Lymphoma, a vascular disease, or Eczema.
Do you need to fast before a cbc lab test?
No. It is not necessary to fast for a CBC. Generally tests like Lipid profiles and Glucose testing are ones that will require you to fast.
CBC is a test that deals with your blood cells.
An MPV stands for "multi-person vehicle" and is the name given to people carriers.
What does Absolute Neutrophils mean?
Absolute neutrophil count (ANC) is a measure of the number of neutrophil granulocytes that are present in the blood. Neutrophils are a type of white blood cell that fight infection.
What does it mean when the MCH is high in your cbc count?
MCH = Mean Corpuscular Hemoglobin.
It is a measure of the amount of hemoglobin in your red blood cells.
The ref. range for adults is between 28-32.
MCH [similar to the MCV] is elevated in: hereditary anemia(s), megaloblastic anemias (pernicious, folic acid deficiency, B12 deficiency), reticulocytosis, artifact (aplasia, myelofibrosis, hyperglycemia, cold agglutinins), liver disease, hypothyroidism, Drugs (anti-convulsants), zidovidune treatment (AIDS).
the GFR EST is a blood test used to estimate the glomerular filtration rate without performing a 24 hour urine for creatinine clearance. It is a calculation involving the patient's serum creatinine, age, and sex. If the patient is African American the equation is adjusted to account for an African American's greater muscle mass.
A Non- AA or non- African American would not require the adjustment.
