WHAT IS A How To Stop Grinding Teeth At Night Kids Emblematica?
How To Stop Grinding Teeth At Night Kids Emblematica Knowing More About Migraine Headaches
Migraine remains to be an enigma on the medical world since its definite cause remains in question. It is often looked as a painful headache which is felt only a single side with the head in the sufferer. Although it can happen on anyone despite of their sex and age, the condition is often seen on women and is usually starting about the patients later in their teenage years. The condition is genetically passable which means that it can explain to you the family and contains a common case to recur around the said family tree.
People with migraines can are afflicted by this aggravating condition all day or even days even though common time frame for a migraine attack is about 4 hours to 72 hours essentially. The overall occurrence can be as enigmatic because the cause because it really doesn't have any certain symptoms also it the way it occurs are often different on different people. As an example, the variety of its frequency is really as low as a couple of times a year to as high as having it as an daily occurrence.
People with chronic migraine might have to endure it after their 50s since the migraine headache attacks would usually go down in its frequency as soon as you passed the said milestone of your life. Little kids as little as 10 years old to adults as old as forty years old are prone to be possessing this condition and would usually start the condition by having symptoms as being a certain light headed feelings that continues into extreme pain in the particular side in the patient's head.
The side in the head also differs on patients to patients of course, if a patient turns into a headache on say the right side in the head then the migraine would usually occur on any particular one side for the rest with the migraine attacks occurrences within the said patient's life. Other symptoms that has to be felt by migraine sufferers are nausea and increased sensitivity to light and sound. In other words, individuals with migraine attacks are extremely sensitive to bright lights and may not be in an environment that's exposed to loud noise for example residential near a building project.
Although migraines' cause is not yet been found, scientists had struggled to discover the definite cause from the disease for over 1700 years. The first case of known and recorded migraine was found by Aretaeus of Cappodocia around the 2nd century AD. This alone proves that the battle against migraine had long started and remains to be commencing despite the type of medical technology we are currently having through this modern age we are living.
The scientists did manage to relate migraine to a trait of hereditary links that is carried genetically through family ties. The number of cases where this happens isn't that many however and therefore migraine is just not categorized like a hereditary disease. Up to this moment, the treatments for migraine headaches are limited to combination of analgesic and antiemetic medication to deal with the headache and nausea that is included with migraine attacks.

How To Stop Grinding Your Teeth Bruxism Guard Cost Scavenge Fires - How to Prevent & Extinguish Marine Main Engine
Scavenge fires are generated by oil igniting with the combustion air inlet ports from the scavenge spaces on main engine diesel engines. They are frightening and dangerous, but they can be avoided by carrying out good watch keeping duties and regular upkeep of the fuel system and fuel injectors.
Scavenge fires are caused by lube-oil, diesel or heavy fuel oil gathering around the area of the scavenge ports. This is ignited by sparks make up the combustion area passing the piston rings and pressing the flammable oil. It is the main watch keeping engineers remit to be familiar with the complexities, control and prevention of scavenge fires however engine. It is also imperative the scavenge spaces should be cleaned out at every opportunity in port and regular inspection from the scavenge drains on the sludge tank done by the watchkeeper.
The following sections examine scavenge fires and also the actions required in the senior watch keeping engineer,
The senior watchkeeping engineer over a main engine diesel engine should familiarise himself with the fuel system. This entails expertise in how the fuel is purified by centrifuge and held in the ready use tanks and also the fuel pump and injection system. He should also be aware with the Chief Engineers standing orders regarding fuel oil injector nozzle cooling temperatures, fuel oil temperatures, fuel oil filter change intervals and keep these as part of his watchkeeping duties.
This is normally carried out by the third engineer; I used to undertake it whilst on watch during quite sea passages. I sailed with one Chief who insisted the Second engineer performed the maintenance. In any case the Chief or Second should at the very least witness the testing with the injectors.
eval(ez_write_tag([[300,250],'brighthubengineering_com-medrectangle-2']));
The ship should carry a lot of spare fuel injectors; enough to change a couple at each port and leave a few of spares to change after scavenge fires.
The spare injectors ought to be stored in racks using the nozzles well clear from the deck to stop acciDental knocks that may block the nozzle atomising holes.
The injector should be gripped in the vice containing jaw protectors and also the nozzle removed. The parts ought to be washed in diesel and any clinker carefully taken out of the face of the nozzle with a copper scraper.
The nozzle should then be gripped inside vice along with the needle ground to the seat using fine grinding paste. Once again wash the nozzle and needle carefully making certain all the grinding paste may be removed. Dry every aspect and reassemble the injector, connecting the inlet on the injector testing pump outlet. Pump up the pressure on the recommended level and adjust the spring accordingly before the injector needle lifts and fuel is injected into a suitable receptacle.
At the recommended pressure the atomisation with the fuel ought to be visible as well as a squeak must be simultaneously heard. No dripping in the nozzle after atomisation is permitted.
Record the injector serial number, pressure which it lifted at and date of test, within the injector maintenance log and re-rack, ready for witnessing from the Chief or Second if required. Be sure to mark on the injector that it has become tested.
Finally, a thing about safety - marine diesel engines fuel supply are at high pressure if using heavy fuel oil will be really hot; I still have the scar in my wrist from an oil spill when I was changing an injector. That was 1967 when I was an engineer with a Sulzer engined Denholm Company Sulphur Tanker. Yuc! What a reek, glad I wasn't a Deck Officer.
Also when testing a fuel valve around the test rig tend not to put you hands anywhere near the atomising fuel, and wear goggles!
A sketch of your injector along with a scavenge space is shown below;
Regular repair off the piston, rings and liners should be carried out, depending on the Chief or Second engineers maintenance programme that may involve the periodic pulling of your piston (more so if a particular cylinder has a record of scavenge fires) as well as the examination of the rings and liners. A survey of these needs to be carried out to make sure that all components are inside makers recommended specs.
Rings needs to be checked for defects and clearances, liners being checked for scratching, wear and ovality.
Regular purifying of the fuel oil by centrifuge, whether it be diesel or heavy fuel must be accomplished to ensure an adequate clean method of getting fuel for your main engine. I had issue with scavenge fires one ships engine and was getting a lot of stick as I maintained the fuel injectors. However we had a new Fourth who, against his Junior Engineers advice still did not clean the oil filters or centrifuges regularly. The dirty fuel blocked the injector nozzles causing them to leak after atomizing, leading to scavenge fires. The junior finally found me for advice; I promoted him and the Fourth got the boot in the next port and sent home ' you can forget scavenge fires, so I cannot emphasis enough the importance of fuel oil filtering and centrifuging.
Page 2 continues the delimas of scavenge fires; as well as the method of extinguishing them.
This used to be done by individual cylinder lubricators which in fact had their reservoirs filled with lube oil every watch and pumped metered amounts of lube oil towards the different cylinders, piped via quills within the cylinder walls. Nowadays I believe it is all area of the lube oil system, though the principles are usually similar. The main problem is over-lubrication, again whilst at sea we were experiencing high levels of lube oil usage, combined with scavenge fires. The lubricators supply oil towards the cylinders through quills connected for the cylinder liner walls and also the lubricators could be operated by hand if needed. The culprit was an Indian greaser who whilst topping in the lubricators was merrily hand cranking away on the lubricators to get the level down so he could put the full Quart of oil inside the reservoir! A quiet word in the lug as well as a boot inside the whatsit sorted that one. So it is crucial that you record the amount of lube oil being utilized per day by the main engine, and adjust the availability accordingly.
Once a scavenge fire starts, hit the engine room emergency button, reduce the engine to its slowest possible revolutions this will likely limit how much fuel oil being admitted to the cylinders. It will also reduce the amount of combustion air for the cylinders, lowering the oxygen content being supplied for the scavenge fire.
The fuel have to be isolated to the cylinder in which the fire is happening by lifting the relative fuel pump plunger clear of the operating cam. The bridge needs to be informed as well as the engine room telegraph put to dead slow ahead, recording the times along with the movements inside log book for future reference.
This may seem a lot to do immediately, but I have experienced some serious scavenge fires while senior watch keeper on Sulzer two-stroke main engines and it may be done having a little help from the recently startled off-duty engineers (we have all been awakened with the banshee wail from the engine emergency siren and subsequent slowing down from the engine beat)
The watch keepers The senior engineer should remain in the controls, junior engineer adjusts the seawater for the lube oil and jacket coolers maintaining operating temperatures.
Other Engineers The rest of engineers should operate scavenge CO2 or mist sprays if fitted, Isolate the fuel by lifting the pump piston rod with the offending cylinders fuel pump cam, increases lube oil compared to that cylinder yourself operating the lubricator to avoid the piston seizing and, keep an eye for the exhaust condition out with the flu, scavenge door temperature and drains to sludge tank. Once the greasers have washed the scavenge space, the senior engineer should inspect the piston rod and gland for signs of excessive scorching. The gland may need stripping if the springs holding the scraping rings have lost their tension through heat through the burning oil; excessive oil usually accumulating for this area. Excessive scorching is going to be evident through the blue color in the gland top keep ring and hang screws.
Engine room Greasers - Once it has become determined that this fire may be extinguished, as well as the scavenge space has cooled enough for cleaning, the scavenge inspection doors needs to be slowly and thoroughly removed. The resultant carbon residue and fuel oil can scraped away then cleaned using rags leaving the area dry and clean. The exhaust gas boiler ought to be fired up to take care of boiler steam pressure and also the offending cylinder lube oil reservoir kept topped up.
Note: It is many, several years since I would have been a seagoing engineer, so please accommodate a bit of age and alcohol related brain damage to this old retired Irish marine engineer, I would be thrilled to answer any relevant queries with the comments section with the end from the article.
