Discuss 3 advantages and 3 disadvantages of having a large Earth based telescope as compared to having a large space telescope.
Suppose that you were given the power to choose 2 telescope projects: one for space and one Earth based. Discuss 6 factors (3 for the space project and 3 for the Earth based project) that you would consider in building the telescopes.
Suppose you personally wanted to buy a telescope (or maybe you already have a telescope) for viewing objects such as nebulae and galaxies. What factors would you consider (or did you consider) in buying a personal telescope? Are any of the factors the same as the factors you chose for the telescope projects?
. The different treatment types are local, regional, and whole body. Local hyperthermia is where heat is applied directly to a tumor or a small area and can be applied directly on the target area or can be applied through probes placed in the specific area. Regional hyperthermia is where heat is applied to a large tissue area. Whole body hypothermia is when a person’s body temperature is raised almost as if they have a fever. For whole body treatment, “blankets, warm water, or a heated chamber are used to warm the person’s body” (Gersten 2017). In the other cases, heat is created through using either microwaves, radiofrequency, and/or ultrasound. Radiofrequency ablation, RFA, is used for local treatment and is the most common type of thermal energy, using “high energy radio waves for treatment” (Cancer.org). In RFA, a needle-like probe is inserted into the tumor “sends radio wave energy directly into the tumor”. RFA is most commonly used in cancer cases where tumors cannot be taken out with surgery, for example, liver, kidney, and lung tumors (Gersten 2017). The temperature used is around 106-113 degrees Fahrenheit and is administered by a device called the BSD-500 (Excellus BCBS). A surface applicator is applied to the tumor and the area is heated for around an hour. Usually hyperthermia is done within an hour of radiation (UCSF). Side effects sometimes occur and include burns, blisters, discomfort, or pain (Cancer.org). According to Excellus BlueCross BlueShield health insurance, their medical policy states that “based upon our criteria and assessment of peer reviewed literature, superficial hyperthermia has been medically proven to be effective and therefore, medically appropriate when used in combination with radiation therapy for the treatment of patients with the following: Superficially recurrent melanoma; chest wall recurrence of breast cancer; or recurrent cervical lymph nodes from head and neck cancer” (Excellus). Although this insurance approves of certain types of hyperthermia, others are only considered investigational to them. The treatments that are considered investigational are interstitial hyperthermia, regional hyperthermia, regional perfusion hyperthermia, and whole-body hyperthermia. The reason the Excellus BlueCross BlueShield and the FDA have not approved other types of hyperthermia treatment is because studies do not have enough patients, do not have a standard technique, are not random or controlled, and do not have long term results. Currently the Food and Drug Administration (FDA) has approved hyperthermia in the treatment of solid surface>GET ANSWER
