Plasma actuators use ionized gas to create aircraft control surfaces without moving parts or hydraulic systems. They offer greater reliability and maneuverability, but altitude and speed affect performance. The technology is practical and has been tested in wind tunnels at supersonic speeds. A plasma actuator is a form of advanced servo mechanism developed primarily for […]
Plasma cutters use high voltage electric arc and compressed gas to cut conductive metals. They create a concentrated arc of plasma that melts a section less than 1/16″ wide and blows it out onto the workpiece. They are lightweight and portable, and can cut up to 2 inches of metal. They prevent warping and paint […]
Spark plasma sintering (SPS) is a fast and cost-effective technique that uses direct current pulses to create spark energy between particles of a material, resulting in high-density structures. It can be applied to ceramics, composites, and nanostructures, and produces uniform heating and density. SPS has low operating costs, short completion times, and can be used […]
CNC plasma cutting systems use superheated gases to cut patterns in materials like sheet metal. The computer interface controls the cutting process, and the plasma cutting head moves in both X and Y directions. Plasma cutting is typically used for two-dimensional manufacturing and is useful for shops that perform precision machining. A computer numerically controlled […]
Plasma machining uses ionized gas to improve surface durability and strength. Techniques include plasma activation, curing, cleaning, and polymerization. Plasma cleaning is popular due to its effectiveness and eco-friendliness. Plasma activation improves adhesion, while plasma polymerization creates stable polymers. Plasma curing is a simpler method of polymer synthesis with high adhesive qualities. Plasma machining uses […]
Blood plasma donation involves plasmapheresis at a donation center, with plasma used to treat rare diseases. Blood is drawn, spun in a centrifuge, and separated into components, with plasma removed and replaced with saline. Donors must provide medical history and be tested for viruses. Rules on frequency and amounts vary, with some experiencing side effects. […]
Plasma is the fourth state of matter, consisting of charged molecules that form gas-like clouds or beams of ions. A plasma torch converts gas into plasma for fusion through metal, cutting and welding. It is used in the automotive, construction and art industries. Safety precautions should be taken when using a plasma torch. Plasma, also […]
Plasma arc welding is a more focused and automated process than gas tungsten arc welding, using a narrow copper orifice to create a plasma arc that can reach high temperatures and speeds. It requires at least two types of gas and can be varied based on key components. However, it is more expensive and complex, […]
Plasma cutters use HF electricity to create a plasma arc for cutting conductive materials. Manual cutters are portable and easy to use, while automatic cutters are more productive but require specialized training. Choosing between the two depends on factors like portability and productivity. Plasma cutting machines use high frequency (HF) electricity to convert pressurized air […]
Plasma cutters are fast and efficient for cutting thick metal, but can be expensive and require proper handling to avoid damage. They don’t need preheating and can cut up to 6 inches deep. Slag buildup and hardened edges are common issues, but can be managed with regular cleaning and careful use. Plasma cutters are hailed […]
Plasma welding uses an electric arc to create a concentrated plasma stream in a small area. It is commonly used in aerospace, automotive, and kitchenware industries. Plasma welding is precise and uses multiple gas sources to produce a powerful heat source. The welder has a narrow nozzle and an electrode inside it. Plasma welding is […]
Plasma donor centers are usually found in urban areas and college towns, and donors must undergo a thorough screening process before donating. Plasma is used for medical purposes and can be donated twice a week for an average payment of $25 USD. Homeless people no longer donate due to the risk of diseases. While plasma […]
Fasting blood glucose (FPG) measures blood sugar levels after a period of not eating, used to monitor diabetes control. Type 1 diabetics have an autoimmune disease, while type 2 diabetics have high blood sugar due to insulin resistance. FPG tests are important for pre-diabetics and should be monitored frequently. Ideal levels range from 80-100 mg/dL, […]
Plasma cutting tables use high pressure inert gas and an electric arc to cut metal and sheet materials. There are three types of plasma cutting: HF contact, pilot arc, and CNC. HF contact is for conductive materials, pilot arc can cut non-conductive materials, and CNC is computer-controlled. A plasma cutting table is used in industrial […]

Plasma donation is similar to blood donation, but involves separating red blood cells from plasma. Plasma can be used to help those with blood clotting issues and is often collected by pharmaceutical companies. Donors may be paid around $15-25 per donation, but should not lie about risky behaviors. Donating plasma too frequently can affect health […]
Plasma cell diseases include amyloidosis, where abnormal proteins build up in organs, solitary plasmacytoma and multiple myeloma, where excess cells form tumors in the bone marrow, MGUS, where abnormal protein levels are stable, and Waldenstrom’s macroglobulinemia, a rare cancer causing blood thickening. There are a variety of diseases that can affect plasma cells, the white […]
Plasma cortisol test measures cortisol levels in the blood, which can help diagnose and manage conditions related to the adrenal gland. Patients may need to fast and stop taking certain medications before the test. Results can indicate conditions such as Cushing’s disease, Addison’s disease, or adrenal insufficiency. Further tests or treatment may be necessary depending […]
Plasma is a distinct phase of matter, often referred to as an ionized gas. It is abundant in the universe and can be found in everyday contexts. Plasmas vary widely and can be classified by parameters such as ionization, temperature, and density. Plasma phenomena can be observed with a plasma ball, and it can be […]
Plasma concentration tests measure the amount of a compound in a plasma sample and can aid in diagnosis, treatment, and monitoring of diseases. Tests can detect imbalances and monitor medication effectiveness and organ function. Reference ranges may be provided for normal results. Plasma concentration is a measure of the amount of a compound present in […]
