pineapple slices were dried using fluidized bed dryer at 80 °c for 3 h. vacuum drying treatments were performed using vacuum oven at 21.5 kpa and 60 °c for 12 h.
cables must be treated as energised and the procedures for working on energised electrical equipment followed until positive tests can be made that prove the cable is de-energised. if the cable’s connections are exposed the connections and attached live parts should be proved to be de-energised and identified before work starts.

any surfaces cut by metal melting methods (i.e., torch cutting, arc gouging) that are not to be rewelded shall have 1/16-inch removed by grinding or other mechanical means and be inspected by the mt or pt method after grinding (uht-83). the requirements of uw
what is flash electropolishing? flash electropolishing is a technique to remove scale or oxidation from the surface of a heat-treated metal. for example, some surgical instruments made of stainless steel (ss) 17-4 will appear brown after welding and/or heat treat. to remove the brown appearance, parts are flash
safe operating procedures (sop’s) are written step-by-step procedures for a specific non-repetitive task which may be hazardous or critical. the purpose of an sop is to provide written guidance for a particular task such that any qualified person can successfully and safely complete the task. sop’s are best developed and used for highly
mechanical removal calls for abrasive cleaning. particularly in repair brazing, where parts may be very dirty or heavily rusted, you can speed the cleaning process by using a grinding wheel, or file or metallic grit blast, followed by a rinsing operation. once the parts are thoroughly clean, it’s a good idea to flux and braze as soon as possible.
food preservation: dehydration. dehydration, or drying, of foods has long been practiced commercially in the production of spaghetti and other starch products.... hot-air dehydration was developed in france in 1795, enabling the commercial production of dehydrated food products, particularly spaghetti and other starch products.

the present paper discusses a number of cases wherein faulty inspection procedures resulted in accidents. these cases are based upon published reports as well as personal experiences, and will deal with the crashes which involved: a 707 freighter (visual examination), a dc-10 (dye penetrant), a small passenger plane (magnetic particle), a 737 (eddy currents), and a 747 freighter
if your handy, turn off the main house gas at the meter. then remove the old dryers gas line from that pipe. then remove any adaptor fitting installed on the gas pipe. install a 1/2 inch by 3/8's inch ball valve type gas shut off valve directly onto the steel gas pipe threads. most commonly, a gasline to a dryer
preheat as necessary for large or complex or heavily cold-worked parts. austenize at 1065 °c (upper end of range) for maximum dissolution of carbides (increases cr in metal to ~13%). inert gas quench to ~room temperature. subcool to -75 °c to transform retained austenite (improves dimensional stability).
passivation is a post-fabrication process that is performed after grinding, welding, cutting and other machining operations that manipulate stainless steel. under ideal conditions, stainless steel naturally resists corrosion, which might suggest that passivating would be unnecessary.

wet skin (standing in water, sweaty) has a resistance of about 1000 ohms. (dry skin will have a higher resistance, and of course an inspector wearing protective gear such as rubber gloves, rubber-soled shoes, standing on an insulated mat, will have still higher electrical resistance, and safety.)

technicians can also shoot 360-degree video when tackling a task for the first time together with a more experienced worker. when executing the task alone, they can verify the different stages of the work through ar devices. this is one way to ensure consistently good results in maintenance work, while also taking safety issues into account.
3. revise work procedures. consideration might be given to modifying steps which are hazardous, changing the sequence of steps, or adding additional steps (such as locking out energy sources). 4. reduce the exposure. these measures are the least effective and should only be used if no other solutions are possible.
