What is DFM?
Design For Manufacturability
What kind of fuel is needed to power the ship the USS Cole?

What is a product design?
Any product example it may be in cunsumer goods, industries etc if they need to launch a new product they need to design a product. the product design consists of cocept to DFM(design for Manufactring). Once the cocept designer come up with a rough design,the product prototype is build with all the product fuctinality finally the product is build as per the product design. From the product design we can know the all the study about product and its functionality
How the black hole began?
First, it starts out as a pinhole, then it starts to get smaller and smaller and later it explodes, ripping through space and it's time continuum creating a giant hole, it starts sucking up light getting more and more energy, if you got sucked in, you would die because all that pressure and energy inside it could destroy anything that goes inside it. There is little agreement. Black holes have however now been found at the centre of all galaxies, in various states of activity. In astronomy they are termed Active Galactic Nuclii (AGN's). The accrete matter from the disc and, eject it on a perpendicular axis (centreline of the electromagnetic toroid (donut). If very active these outflows are 'quasar' jets. If all galactic material has been devoured the AGN is spent and the ejected material will start to rotate bodily on the new perpendicular axis (DFM theory). This rotation would then be the start of a new black hole at it's centre. Smaller ones may be at Stellar Scale, as 'neutron stars' after a supernova. (see the core of the Crab nebula)
How much fuel does an aircraft carrier have?
Modern nuclear aircraft carriers (of which both the US and France have deployed) are powered by 2 nuclear reactors. In general, they have enough nuclear fuel rods on board to keep running for about 20-25 years. However, many other aircraft carriers are conventionally powered, and run on ordinary fuel oil. The amount of fuel oil on board varies widely, though most have a minimum range of 10,000 nm at a standard cruising speed. Long-range "fleet" carriers of world war two (the USS Essex class being the best example) typically had enough fuel oil to cruise at 15 knots (half of top speed) for around 20,000 nm. In addition to fuel for the ship itself (for propulsion and to generate power to run the ship's equipment), all aircraft carriers need to carry avgas for the aviation units. Once again, the amount varies by the size, design, and era of the carrier, and is generally tailored to meet the fuel consumption requirements for the expected aircraft carried. The USN Nimitz class, for example, carries around 3 million gallons of aviation gas, which gives it somewhere around two weeks of continuous air operations.
Emergency airway puncture?
DefinitionEmergency airway puncture is insertion of a hollow needle into the airway done to treat life-threatening choking.Alternative NamesNeedle cricothyrotomyDescriptionIn an emergency situation, when someone is choking and all other efforts to assist with breathing have failed, a hollow needle or tube can be inserted into the throat, just below the Adam's apple (cricoid cartilage).In a hospital setting, a small cut in the skin is made before inserting the needle.Why the Procedure Is PerformedA cricothyrotomy is recommended as an emergency procedure to relieve an airway obstruction until surgery can be done to place a breathing tube (tracheostomy).RisksRisks for any surgery are:BleedingInfectionAdditional risks include trauma to the voice box (larynx), thyroid gland, and esophagus, and perforation (tearing) of the lungs and other body parts in the chest, leading to a collapsed lung and air collecting around the heart.After the ProcedureEmergency airway puncture (cricothyrotomy) can be quite effective in temporarily relieving an airway obstruction, but it must quickly be replaced by a more effective means of ventilation.Outlook (Prognosis)What happens will depend on the cause of the airway obstruction and how quickly the person receives a better means of ventilation.See: TracheostomyReferencesGoldenberg D, Bhatti N.

Acute upper airway obstruction?
DefinitionAn acute upper airway obstruction is a blockage of the upper airway, which can be in the trachea, voice box (laryngeal), or throat (pharyngeal) areas.Alternative NamesAirway obstruction - acute upperCauses, incidence, and risk factorsCauses of acute upper airway obstruction include:Allergic reactions in which the trachea or throat swell closed, including allergic reactions to a bee sting, peanuts, antibiotics (penicillin), and blood pressure medications (ACE inhibitors)Chemical burnsand reactionsCroupEpiglottitis(infection of the structure separating the trachea from the esophagus)Fire or burns from breathing in smokeForeign bodies -- such as peanuts and other breathed-in foods, pieces of a balloon, buttons, coins, and small toysViral or bacteria infectionsPeritonsillar abscessRetropharyngeal abscessThroat cancerTracheomalaciaTraumaVocal cord problemsSymptomsSymptoms vary depending on the cause, but some symptoms are common to all types of airway blockage. They include:Agitation or fidgetingBluish color to the skin (cyanosis)Changes in consciousnessChokingConfusionDifficulty breathingGasping for airPanicUnconsciousnessWheezing, crowing, whistling, or other unusual breathing noises indicating breathing difficultySigns and testsPhysical examination may show:Decreased breath sounds in the lungsRapid, shallow, or slowed breathingTests are usually not necessary, but may include:BronchoscopyLaryngoscopyX-raysTreatmentIf the person has a complete obstruction and is unable to speak or breathe, the Heimlich maneuver may be lifesaving.Treatment depends on the cause of the blockage.Objects stuck in the airway may be removed with a laryngoscope or bronchoscope.A tube may be inserted into the airway (endotracheal tube or nasotracheal tube).Sometimes an opening is made directly into the airway (tracheostomy or cricothyrotomy).Expectations (prognosis)Prompt treatment is often successful. However, the condition is dangerous and may be fatal, even if treated.ComplicationsInability to relieve the obstruction can cause:Brain damageBreathing failureDeathCalling your health care providerAirway obstruction is an emergency. It is a good idea to learn how to clear an airway of a foreign body by using a method such as the Heimlich maneuver.Diseases in which airway obstruction develops over a period of hours will allow time to get to a hospital. If an acute airway obstruction occurs, call 911 or your local emergency number for medical help. Do what you can to maintain breathing until medical help arrives.PreventionPrevention depends on the cause of the upper airway obstruction.The following methods may help prevent an obstruction:Eat slowly and chew food completely.Don't drink too much alcohol before or while eating.Keep small objects away from young children.Make sure dentures fit properlyReferencesManno M.

What oscillates in electromagnetic waves?
In electromagnetic waves, the electric and magnetic fields oscillate perpendicular to each other as the wave propagates through space. These oscillations are what carry the energy and information from one place to another.
