However, these units require more precision and need a professional to cast and fit them individually (Tierney, 2011).
RIC, or receiver in canal, models are a newer development in hearing aid technology and are more suitable for those with mid-severe hearing loss. When compared to a classic behind the ear hearing aid, the receiver of the RIC (the actual loudspeaker) is place on the ear-tip instead of in the housing, which drastically reduces the size of the unit. The RIC model actually has three parts: the housing that sits behind the ear (1); a thin wire that connects the housing to the receiver (2), and the receiver that goes directly into the ear canal (3). Despite its size, the RIC model is very discreet and automatic (Dillon, 2012).
RIC's are similar to Behind the Ear devices but house the speaker in the ear by replacing the tube and a flexible piece to improve sound quality and reduce extraneous "noise." They are available in a wide variety of shapes and sizes, and even have color tones to match the individual's skin. Studies show that RIC instruments...
RIC users report more satisfaction with the unit; the appearance, retention, comfort, and speech clarity. These units also vary in price depending on the complexity and automation allowed, as well as the sophistication of the computer chip installed.

HIV Education HIV rates are stabilized, but there are still many at-risk persons. As each generation reaches sexual maturity, they need to continually be educated about the risks of HIV / AIDS in order to curtail the spread of the disease. There has been considerable research as to the best ways for the education system in particular to handle this issue, and this report will synthesize some of those issues. There
HIV Infection A medical condition in which the immune system is destroyed by a virus called as Human Immune Deficiency Virus is known as HIV infection. The loss of immune function deteriorates the ability of the body to fight against various types of pathogenic infections (caused by harmful micro-organisms) (Quinn). The virus attacks the immune cells of the body which are basically the white blood cells (CD4 T cells) due to
AIDS in Afica HIV / AIDS in Africa An Overview of how this Terrible Disease has Rampaged the Population in Africa and what might be done about it in the Future. The spread of AIDS has reached epidemic proportions on the African Continent. There are many factors that can be attributed to the spread of this phenomenon. Lack of modern health care facilities and trained medical professionals is often cited as a cause
According to Lisam & Lisam (2009), the need for doctor's advice is also fueled by the constant emergence and experiment of new and different medicines for HIV and AIDS (p. 269). Problems Associated with Diarrhea Caused by HIV Medications: For people living with HIV / AIDS, the negative impacts of drugs and food intake and the impact of drugs on metabolism, excretion, and absorption of nutrients may have considerable negative effects
A hemophiliac, young Ryan had contracted the disease through the infusion of blood resources that had long served as his life force; and then that life force, infected with HIV, failed him (Levitt & Rosenthal, 1999). As the young boy bravely faced the demons of the ravaging disease, friends, relatives and outpourings of public support and love marked his journey. Surrounded by his family, and new friends like the
HIV / AIDS Autoimmune deficiency syndrome (AIDS) first came to the public's attention in the United States in the early 1980s. In Africa, the cities of Rwanda, Zaire, Zambia and Uganda were decimated, and cases began cropping up all over the world. In rare blood samples dating back to 1959, antibodies to HIV were detected (Crowley, 1993, p. 46), and yet the virus did not seem to become a problem until
