Voiceless liquids: 11 (unilateral voiceless 1); rh (voiceless r).
Initial 1 and r became 11 and rh, as seen in examples in (I) above; but between vowels they remained.
The liquids 1 and r were brought into the system, the initial forms 11 and rh being regarded as " radical."

Other factors that cause neonatal jaundice are ABO incompatibility and Rh incompatibility.
Rh incompatability-A factor of blood classified as negative or positive and related to the reaction that occurs between different types.
In the past Rhesus (Rh) blood factor incompatibility between the mother and child was a major cause of kernicterus.
Rh incompatibility also may be treated by exchange transfusion.
In cases of known Rh incompatibility, the mother is given an injection of RhoGAM, an immune globulin preparation, at about 28 weeks of pregnancy and again immediately after the child's birth.
Kernicterus: also called Rh incompatibility, a condition that develops when there is a difference in Rh blood type between that of the mother (Rh negative) and that of the fetus (Rh positive).
Indications that are more controversial include breech presentation, previous c-section, major congenital anomalies, cervical cerclage, and severe Rh isoimmunization.
Rh blood incompatibility-Incompatibility between the blood of a mother and her baby due the absence of the Rh antigen in the red blood cells of one and its presence in the red blood cells of the other.
Rh disease, for example, has been controlled by the advent of anti-Rh globulin; its administration to Rh-negative mothers has reduced one risk factor for CP.
Incompatibility between the Rh blood types of mother and child (mother Rh negative, baby Rh positive) can result in severe anemia in the baby (erythroblastosis fetalis).
Rh disease in the newborn is rare in developed countries due to routine screening of maternal blood type and routine prevention of anti-Rh antibodies in Rh negative women after each birth of an Rh positive infant.
Several specific antigens are responsible for the incompatibilities: Rh type incompatibility, ABO blood group incompatibility, and other incompatibilities involving antigens known as Kell, Duffy, M, N, and P, among many others.
Rh factor: About 15 percent of people lack a certain blood protein called Rh factor and are called Rh negative.
These can be avoided if the mother is given a substance called Rh immune globulin (RhIg) at approximately 28 weeks into the pregnancy and again within 72 hours after the baby is born.
Rh incompatibility may develop when a woman with Rh-negative blood becomes pregnant by a man with Rh-positive blood and conceives a fetus with Rh-positive blood.
This transfer stimulates maternal antibody production against the Rh factor, which is called isoimmunization.
Maternal-fetal incompatibilities of ABO blood types leading to neonatal erythroblastosis are less severe and less common than those of the Rh factor.
Another red blood cell antigen, called the Rh factor, also plays a role in describing a person's blood type.
A person with at least one copy of the gene for the Rh factor has Rh-positive blood; if no copies are inherited, the person's blood type is Rh-negative.
There are two types of incompatibility diseases: Rh incompatibility disease and ABO incompatibility disease.
Both diseases have similar symptoms, but Rh disease is much more severe, because anti-Rh antibodies cross over the placenta more readily than anti-A or anti-B antibodies.
As a result, a greater percentage of the baby's blood cells may be destroyed by Rh disease.
Prior to 1946 (when newborn blood transfusions were introduced) 20,000 babies were affected by Rh disease yearly.
Further advances, such as suppressing the mother's antibody response, have reduced the incidence of Rh disease to approximately 4,000 cases per year.
Rh disease only occurs if a mother is Rh-negative and her baby is Rh-positive.
For this situation to occur, the baby must inherit the Rh factor gene from the father.
Rh disease and ABO incompatibility disease are caused when a mother's immune system produces antibodies against the red blood cells of her unborn child.
If the father is Rh-positive, an antibody screen is done to determine whether the Rh-negative woman is sensitized to the Rh antigen (developed isoimmunity).
Therefore, all mothers who have Rh-negative blood and no apparent sensitization (as indicated by antibody titer) should be treated with a standard 300g dose of Rh(D) immune globulin (Rhogam) at about 28 weeks of gestation.
Rh factor-An antigen present in the red blood cells of 85% of humans.
A person with Rh factor is Rh positive (Rh+); a person without it is Rh negative (Rh-).
The Rh factor was first identified in the blood of a rhesus monkey and is also known as the rhesus factor.
Exchange transfusions may be given for high-risk infants, especially those with blood group (ABO) or type (Rh positive infants born to Rh negative mothers) incompatibilities.
Your Rh factor can affect you and your baby's health, which is why it's important to check your Rh factor in pregnancy early on.
However, you may wonder why your Rh factor is being checked and how this affects your pregnancy.
Rh factor (abbreviated from Rhesus Factor) is not something that you can change--your Rh factor was decided when you were conceived, as determined by the Rh factors of your mother and father.
There are two kinds of Rh factors: positive and negative, with positive being the most common (negative is actually quite rare).
In everyday life, whether you are Rh positive or negative has no impact on your health or life; however, when you are pregnant, an incompatibility between your own Rh factor and your baby's can cause significant pregnancy complications.
Rh factor is determined by the presence or absence of a certain protein in your blood.
Most people have this protein and are Rh positive.
If you do not have this protein, your blood is Rh negative, which, by itself, is not a problem.
The problem arises because it is more likely that the father's blood is Rh positive than negative.
Incompatibility in Rh factors between pregnant mother and unborn baby occurs because the mother's body may produce antibodies targeted towards the baby's blood.
At your first prenatal visit, your Rh factor will be tested alongside your blood type and several other pregnancy blood tests.
If you are Rh negative, your doctor will probably recommend that the father of your child be tested for Rh factor.
You will likely be tested to see if your body is producing antibodies to Rh positive blood.
If your body is not producing antibodies to Rh positive blood, you will likely be given the option of receiving an injection of Rh immune globulin, which can prevent your body from starting to produce such antibodies.
It's important to also have an injection of it after the baby is born if the baby tests Rh positive at birth.
While it may seem complicated, your doctor or midwife can explain to you all of the precautions and treatments that can go with an Rh negative mother and Rh positive father.
In most cases, you will be tested for Rh factor and never hear another word about it, which means that you are Rh positive and that neither you nor your baby risk anything regarding Rh factor.
The sensor will provide you with a percentage number rated in RH.
For example, a reading of 60 percent RH means you have damp, but not wet, crawl space.
The RH percentage is important to know because that indicates how many times the air in the crawl space has to flow through the dehumidifier in order for the unit to do its job properly.
