The method used to treat brain cancer by directing radiation at precise brain locations is called stereotactic radiosurgery (SRS).

SRS is a non-invasive, high-precision radiation therapy that uses focused beams of radiation to target tumors or other abnormalities in the brain with minimal damage to surrounding healthy tissue. The procedure typically involves the use of a stereotactic frame or a specialized mask to immobilize the head and ensure accurate targeting of the radiation beams.

SRS is typically used for small to medium-sized tumors that are difficult to reach with traditional surgery, as well as for tumors that have recurred after previous treatment. The procedure is usually performed in a single session, although in some cases, multiple sessions may be needed.

To check the internal temperature of a beef roast, a penetration thermocouple probe should be used.

A penetration thermocouple probe is designed to be inserted into food to measure its internal temperature accurately. It is a type of probe that is pointed and thin, allowing it to penetrate through the surface of the food and reach the center where the temperature is most critical. A beef roast is a dense food that requires a probe that can accurately measure its internal temperature, and a penetration probe is the most suitable for this purpose. Other types of thermocouple probes such as immersion, surface, and air probes are designed for different types of temperature measurement applications.

The condition that sometimes results in the development of a "buffalo hump" and "moon face" is Cushing syndrome (option 1).

These physical features are caused by excessive cortisol production, leading to fat redistribution in the body.

When the body is subjected to prolonged exposure to excessive quantities of the hormone cortisol, Cushing syndrome, a rare hormonal condition, develops. The hormone cortisol controls a wide range of physiological processes, including immune response, blood pressure, and metabolism. Cushing's syndrome can be brought on by a number of things, including tumours on the pituitary or adrenal glands, chronic corticosteroid use, or other underlying medical disorders. Cushing's syndrome symptoms might include weight gain, especially in the belly and around the face, thinning skin, high blood pressure, and mood swings. Treatment options include surgical intervention, medication to lower cortisol levels, and addressing the underlying cause.

In a pre-perm analysis, it is essential to assess various hair characteristics to ensure a successful perm process. The key characteristics to evaluate include porosity, elasticity, texture, and the additional factor, which is the hair's current condition.

1. Porosity: This refers to the hair's ability to absorb and retain moisture. It is crucial to assess porosity to determine how well the hair can absorb the perm solution, which will influence the overall outcome.

2. Elasticity: Evaluating hair elasticity helps determine its ability to stretch and return to its original shape without breaking. This is important for perms, as hair with low elasticity may break or be damaged during the process.

3. Texture: Hair texture refers to the thickness of individual hair strands. Different textures may require different perm solutions or processing times, so it's essential to understand the client's hair texture.

4. Hair condition: Lastly, assess the overall health of the hair. Consider any previous chemical treatments, damage, or other factors that may impact the perm's success. Healthy hair is more likely to yield a successful perm, while damaged hair may require extra care or alternative treatments.
