Reactive attachment disorder (RAD) is a condition that affects young children who have not formed secure attachments to their primary caregivers, leading to maladaptive social behaviors. It can be caused by abuse, neglect, institutionalization, or a lack of stable family life. Symptoms include disinterest, withdrawal, and unfamiliar behavior. Treatment involves therapy and forming healthy attachments, […]
Reactive ion etching is a microfabrication technology that removes substances from semiconductors without sacrificing wafer integrity. It uses a vacuum chamber with gas and electromagnetic fields to create plasma and remove defects. It is more expensive than wet etching but more effective in hard-to-reach areas. Reactive ion etching is a type of technology used in […]
Reactive programming automatically maintains an application’s state when data changes. Variables are constantly re-evaluated as other variables change, allowing the program to react to data changes. Reactive programming is useful for real-time interpretation of data streams, but there are no fully implemented reactive programming languages. Reactive programming is a computer science concept that describes the […]
A special diet is recommended for treating reactive hypoglycemia, with restrictions on cane sugar, high fructose corn syrup, starch, alcohol, and caffeine. The diet can be either high in protein or high in complex carbohydrates, but both require a higher intake of healthy fats. Eating small, frequent meals is also important. Reactive hypoglycemia, or low […]
Reactive hypoglycemia can cause symptoms such as dizziness, increased heart rate, and high blood pressure. It occurs when the body produces too much insulin after consuming sugar, causing blood glucose levels to drop. Severe symptoms may require hospitalization, but emergency intake of energy-producing foods can help manage milder symptoms. Special diets can also be recommended […]
Reactive sputtering is a process that uses a positively charged reactive gas to deposit a thin film onto a substrate material. The target material is released into a vacuum chamber with a low-pressure atmosphere consisting of a reactive gas, and exposed to a high-intensity magnetic field. This process greatly increases the rate at which a […]
Reactive airway disease causes wheezing, shortness of breath, and coughing after exposure to irritants. It is often misdiagnosed as asthma, but has no known cause and may not respond to asthma medication. Proper diagnosis is important for effective treatment. Reactive airway disease, also known as reactive airway dysfunction syndrome (RADS), is a respiratory condition characterized […]
A responsive classroom emphasizes simultaneous academic and social learning, autonomy, and confidence-building for students. It considers individual needs and encourages interaction through open-ended questions, group work, and an environment where mistakes are opportunities for growth. Students play an active role in setting the tone and may meet for a morning check-in. Teachers can receive training […]
Reactive attachment disorder (RAD) is caused by emotional neglect in childhood and can lead to difficulty forming relationships and social interactions. Symptoms vary by age and can include refusal of food, stubbornness, and manipulation. RAD can persist into adulthood and lead to drug or alcohol abuse and criminal behavior. Adolescents with RAD may exhibit inappropriate […]
Panel reactive antibodies (PRA) are created by the body to attack foreign tissue, and can be triggered by blood transfusions, transplants, and pregnancy. PRA levels are important to monitor in kidney transplant candidates, as high levels can make it difficult to find a matched donor and increase the risk of organ rejection. Immunoadsorption and plasmapheresis […]
