Interview Questions.

Question 1. Can You Predict Earthquakes?

Answer :

No. Neither the USGS nor Caltech nor every other scientists have ever predicted a first-rate earthquake. They do no longer understand how, and that they do not count on to know how any time within the close to destiny. However primarily based on medical data, probabilities can be calculated for ability future earthquakes. For example, scientists estimate that over the following 30 years the opportunity of a prime EQ going on inside the San Francisco Bay place is sixty seven% and 60% in Southern California.

Question 2. Can Animals Predict Earthquakes?

Answer :

Changes in animal behavior cannot be used to predict earthquakes. Even although there had been documented cases of unusual animal behavior prior to earthquakes, a reproducible connection between a selected behavior and the incidence of an earthquake has no longer been made. Animals change their conduct for many motives and for the reason that an earthquake can shake millions of humans, it is probably that a few of their pets will, by means of risk, be performing surprisingly before an earthquake.

Question three. Can You Prevent Large Earthquakes By Making Lots Of Small Ones, Or By "lubricating" The Fault With Water?

Answer :

Seismologists have found that for each significance 6 earthquake there are 10 of magnitude five, a hundred of value four, 1,000 of magnitude 3, and so forth because the events get smaller and smaller. This appears like loads of small earthquakes, however there are by no means enough small ones to dispose of the occasional big occasion. It would take 32 magnitudes 5's, 1000 importance 4's, 32,000 significance 3's to identical the electricity of 1 significance 6 event. So, even though we usually file many more small activities than large ones, there are never enough to cast off the need for the occasional large earthquake.

As for "lubricating" faults with water or a few different substance, injecting high stress fluids deep into the ground is understood so as to trigger earthquakes to occur earlier than might were the case without the injection. However, this would be a risky pursuit in any populated place, as one may cause a dangerous earthquake.

Question 4. Can Some People Sense That An Earthquake Is About To Happen? (earthquake Sensitive)?

Answer :

There is no scientific reason behind the symptoms a few humans declare to have previous an earthquake, and more often than no longer there's no earthquake following the signs and symptoms.

Question five. Is There Earthquake Weather?

Answer :

In the 4th Century B.C., Aristotle proposed that earthquakes have been due to winds trapped in subterranean caves. Small tremors were idea to were due to air pushing on the cavern roofs, and large ones through the air breaking the surface. This concept cause a belief in earthquake weather, that due to the fact a huge amount of air changed into trapped underground, the weather could be warm and calm earlier than an earthquake. A later theory stated that earthquakes came about in calm, cloudy situations, and have been typically preceded through strong winds, fireballs, and meteors.

However, there is no connection among climate and earthquakes. They are the result of geologic approaches within the earth and might appear in any climate and at any time during the yr. Earthquakes originate miles underground. Wind, precipitation, temperature, and barometric strain changes affect handiest the surface and shallow subsurface of the Earth. Earthquakes are targeted at depths nicely out of the reach of climate, and the forces that purpose earthquakes are a great deal large than the weather forces.

Earthquakes arise in all types of weather, in all climate zones, in all seasons of the yr, and at any time of day. Sometimes, we're requested: "Do earthquakes alternate the climate in any way? Earthquakes themselves do no longer purpose weather to trade. Earthquakes, but, are part of worldwide tectonics, a manner that regularly changes the elevation of the land and its morphology. Tectonics can motive inland areas to become coastal or vice versa. Changes giant to adjust the climate arise over tens of millions of years, however, and after many earthquakes.

Question 6. Are There More Earthquakes In The Morning/in The Evening/at A Certain Time Of The Month?

Answer :

Earthquakes are equally as possibly to arise at any time of the day or month or yr. The elements that adjust between the time of the day, month, or 12 months do no longer have an effect on the forces within the earth that cause earthquakes.

Question 7. Can The Position Of The Moon Or The Planets Affect Seismicity?

Answer :

The moon, solar, and other planets have an influence on the earth inside the form of perturbations to the gravitational field. The relative amount of influence is proportional to the objects mass, and inversely proportional to the rectangular of its distance from the earth. No considerable correlations had been diagnosed between the fee of earthquake prevalence and the semi-diurnal tides whilst using large earthquake catalogs. There have, but, been some small however extensive correlations mentioned among the semi-diurnal tides and the charge of occurrence of aftershocks in a few volcanic regions, such as Mammoth Lakes.

Aircraft Maintenance Interview Questions
Question 8. Can The Ground Open Up During An Earthquake?

Answer :

Shallow crevasses can form during earthquake triggered landslides, lateral spreads, or different forms of floor disasters. Faults, but, do no longer open up throughout an earthquake. Movement happens alongside the plane of a fault, now not perpendicular to it. If faults spread out, no earthquake might arise because there might be no friction to lock them together.

Question nine. Why Are We Having So Many Earthquakes? Has Earthquake Activity Been Increasing? Does This Mean A Big One Is Going To Hit? We Haven't Had Any Earthquakes In A Long Time; Does This Mean That The Pressure Is Building Up And There Will Be A Big One?

Answer :

Although it could appear that we're having extra earthquakes, earthquakes of significance 7.0 or more have remained fairly steady all through this century and, in keeping with our statistics; have truly seemed to lower in current years. A partial clarification can also lie within the reality that in the last two decades, we've got really had an boom in the variety of earthquakes we have been capable of find each year. This is because of the notable growth within the number of seismograph stations within the global and the many improvements in international communications.

In 1931, there have been approximately 350 stations running inside the international; these days, there are more that 4,000 stations and the facts now is available in hastily from these stations by using telex, computer and satellite tv for pc. This growth within the quantity of stations and the extra timely receipt of information has allowed us and different seismological facilities to locate many small earthquakes which have been undetected in earlier years, and we are able to discover earthquakes greater swiftly. The NEIC now locates approximately 12,000 to 14,000 earthquakes every 12 months or approximately 35 according to day. Also, due to the enhancements in communications and the multiplied interest in herbal failures, the general public now learns about extra earthquakes.

According to long-time period facts (since approximately 1900), we expect approximately 18 predominant earthquakes (7.Zero - 7.9) and one incredible earthquake (8.Zero or above) in any given 12 months. However, allow us to check what has took place in the beyond 32 years, from 1969 through 2001, up to now. Our facts show that 1992, and 1995-1997 were the most effective years that we've got reached or exceeded the lengthy-time period average range of most important earthquakes due to the fact that 1971. In 1970 and in 1971 we had 20 and 19 major earthquakes, respectively, however in different years, the full changed into in lots of cases properly below the 18 per year, which we may also count on based totally on the long-term average.

A temporal increase in earthquake pastime does no longer suggest that a large earthquake is about to occur. Similarly, quiescence, or the lack of seismicity, does no longer mean a massive earthquake is going to show up.

Question 10. Do Earthquakes Cause Volcanoes?

Answer :

No, there are different earth techniques responsible for volcanoes. Earthquakes may also occur in a place earlier than, throughout, and after a volcanic eruption, however they're the end result of the active forces linked with the eruption, and no longer the purpose of volcanic pastime.

Question eleven. What Is Dengue Fever (df)?

Answer :

Dengue infection is because of a virulent disease. It occurs commonly as dengue fever. Occasionally the patient laid low with dengue may also broaden bleeding. Common web sites for bleeding are nostril, gums or pores and skin. Sometimes, the patient may have espresso ground vomiting or black stools. This indicates bleeding in gastro intestinal tracts and it's far severe. The patient with dengue who has bleeding has dengue haemorrhagic fever (DHF). Rarely the affected person affected by dengue may additionally expand surprise, then it's far called dengue shock syndrome (DSS).

Question 12. When Should I Suspect Dengue?

Answer :

Dengue should be suspected if you have sudden onset of fever. The fever is high 103-one zero five tiers F or 39-forty degrees C. It is accompanied with severe headache (by and large within the forehead), ache behind the eyes, frame aches and pains, rash at the skin and nausea or vomiting. The fever lasts for 5-7 days. In some patients, fever comes down on 3rd or 4th day however comes back. All the above signs and symptoms may not be present within the affected person. The patient feels much discomfort after the contamination.

Safety Officer Interview Questions
Question thirteen. There Are Several Types Of Fever, When Should Dengue Be Suspected?

Answer :

The characteristics of dengue that make it distinct from other causes of fever are the pain behind the eyes, severe pains inside the muscle tissue, extreme joint pains, and pores and skin rashes. These capabilities make the diagnosis of suspected Dengue probably. The excessive joint pains as a result of DF is the cause why DF is likewise referred to as spoil-bone fever.

Question 14. What Is The Difference Between Suspected And Probable Case Of Dengue?

Answer :

If a patient suspected to be having dengue has decreased platelets or an growth in blood haematocrit, then the affected person has likely dengue. These extra findings make dengue more likely. Patients with dengue might not have a excessive haematocrit if the character turned into anaemic to start with. 

Question 15. Can You Get Dengue Again After Suffering From It Once?

Answer :

It is viable to get dengue more than as soon as. Dengue can arise because of four extraordinary but related strains of dengue virus. If someone has suffered from one virus, there can be a repeat prevalence of dengue if a distinctive pressure is worried ultimately. Being affected by one strain gives no safety in opposition to the others. A character ought to be afflicted by dengue greater than as soon as in her/his lifetime. 

Question 16. Can The Diagnosis Of Dengue Be Confirmed?

Answer :

There are laboratory checks that offer direct or indirect proof for dengue fever. These exams provide evidence for the incidence of dengue infection. There are some extra checks that may help to perceive the type of dengue infection. The tests for confirmation of Dengue need to be finished in reliable laboratories.

Question 17. How Can Someone Get Dengue Fever?

Answer :

Dengue fever happens following the chunk of an infected mosquito Aedes aegypti.This sort of mosquito has a weird white noticed body and legs and is easy to apprehend even by means of laymen. It breeds in clean water (see Question 20) and has a flight variety of handiest one hundred - 2 hundred metres. The mosquito receives the Dengue virus after biting a individual infected with dengue virus. 

Question 18. When Does Dengue Develop After Getting The Infection?

Answer :

After the entry of the virus in the man or woman, it multiplies inside the lymph glands within the body. The symptoms develop when the virus has extended in enough numbers to reason the signs and symptoms. This occurs generally about 4-6 days (average) after getting infected with the virus. 

Logistics Interview Questions
Question 19. Can People Suffer From Dengue And Not Appear Ill?

Answer :

Yes, There are many folks that are infected with the virus and do not be afflicted by any signs or signs of the ailment. For each patient with signs and symptoms and signs there can be 4-five folks with no signs or with very mild signs. 

Question 20. Can Dengue Fever Be Treated At Home?

Answer :

Most patients with dengue fever can be treated at domestic. They have to take relaxation, drink masses of fluids that are to be had at home and consume nutritious weight-reduction plan. Whenever to be had, Oral Rehydration Salt/ORS (commoin treating diarrhoea) is most effective. Sufficient fluid intake is very critical and turns into greater essential in case DF progresses into DHF or DSS wherein loss of body fluid / blood is the most salient function. It is critical to look for chance symptoms and speak to the physician as quickly as someone or extra of those are found.

Question 21. What Is The Treatment? Is It Curable?

Answer :

Like maximum viral sicknesses there's no unique treatment for dengue fever. Antibiotics do now not assist. Paracetamol (may be purchased with out prescription) is the drug of preference to convey down fever and joint ache. Other drug treatments along with Aspirin and Brufen have to be avoided because they could increase the hazard of bleeding. Doctors need to be very careful while prescribing medicines. Any drugs that decrease platelets must be averted.

Question 22. Can Dengue Fever Become Dangerous?

Answer :

The contamination can come to be risky when you consider that it can cause damage to the blood vessels. The harm may additionally range from multiplied permeability of the blood vessels, inflicting leakage of blood fluid/plasma into numerous organs to absolutely broken blood vessels that reasons bleeding. The signs and signs and symptoms of dengue hemorrhagic fever and dengue surprise syndrome are related to harm to the blood vessels and derangement in functioning in components of blood that assist it to clot.

Question 23. Can People Die From Dengue Fever?

Answer :

People who suffer from dengue fever haven't any danger of demise however a number of them increase Dengue Hemorrhagic Fever or Dengue Shock Syndrome. In some of those instances dying can arise. With right treatment, the patients with Dengue hemorrhagic fever and dengue shock syndrome can get better completely. Good remedy supplied in time can keep most lives.

Question 24. When Should A Patient Suffering From Dengue Go To The Hospital Or Consult A Doctor?

Answer :

Generally the development in the direction of dengue hemorrhagic fever or dengue shock syndrome arise after three-5 days of fever. At this time, fever has often come down. This might also misinform lots of us to trust that the patient is heading towards restoration. In fact, that is the most dangerous period that requires high vigilance from care-givers. The signs and symptoms and signs and symptoms that have to be looked for are excessive pain in the abdomen, chronic vomiting, bleeding from any website online like, bleeding inside the skin acting as small red or purplish spots, nose bleed, bleeding from gums, passage of black stools like coal tar.

Bring the affected person to the sanatorium every time the primary two signs and symptoms, particularly, intense ache within the stomach and chronic vomiting are detected. Usually it is too past due if we wait until bleeding has happened. The most dangerous form of dengue is the dengue surprise syndrome. It is identified by way of signs like excessive thirst, pale and bloodless skin (due to very low blood pressure), restlessness and a feeling of weak spot.

Question 25. Is There A Vaccine To Prevent Dengue Fever?

Answer :

A vaccine has been advanced to prevent dengue fever but it's far nevertheless beneath trial. It isn't always but to be had inside the marketplace. Scientific development is possibly to assist in prevention of dengue fever with the aid of vaccination within the years to come. 

Question 26. Are There Any Long Term Ill Effects Of Dengue Fever?

Answer :

Most those who suffer from dengue fever recover in 1-2 weeks time. Some may additionally experience worn-out for numerous weeks. However, if signs persist after this era, consult a physician.

Question 27. Where Does The Mosquito That Spreads Dengue Live?

Answer :

The highly domestic mosquito Aedes aegypti rests interior, in closets and different dark locations. Outside it rests where it's far cool and shaded. The lady mosquito lays her eggs in water packing containers in and around the houses, and other dwellings. These eggs will increase, turn out to be larvae, and similarly become adults in approximately 10 days.

Personnel Management Interview Questions
Question 28. How Can The Multiplication Of Mosquitoes Be Reduced?

Answer :

Dengue mosquitoes breed in stored, exposed water collections. Favoured locations for breeding are barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks, discarded bottles, tins, tyres, water coolers and so on. To prevent the mosquitoes from multiplying, drain out the water from wasteland coolers/window air coolers (while not in use), tanks, barrels, drums, buckets and many others. Remove all items containing water (e.G. Plant saucers etc.) from the residence. Collect and wreck discarded boxes in which water collects e.G. Bottles, plastic baggage, tins, used tyres and many others. In case it isn't always possible to drain out numerous water collections or to absolutely cover them, use TEMEPHOS, an insecticide, ( logo name Abate1 element according to million consistent with the nearby hints to prevent larvae from growing into adults.

Question 29. How Can I Prevent Mosquito Bites To Prevent Dengue?

Answer :

There is not any way to tell if a mosquito is wearing the dengue virus. Therefore, human beings need to defend themselves from all mosquito bites. Dengue mosquitoes chew in the course of the day time for the duration of the day. Highest biting depth is about 2 hours after dawn and before sunset.Wear full sleeves garments and lengthy attire to cowl as an awful lot of your body as viable. Use repellents- be careful in using them in younger children and old humans.

Use mosquito coils and electric powered vapour mats at some point of the daytime additionally to save you dengue.Use mosquito nets to protect children, vintage humans and others who may also relaxation for the duration of the day. The effectiveness of those nets can be stepped forward by means of treating them with permethrin (pyrethroid insecticide). This bed-net is known as Insecticide Treated Nets and are extensively used in the prevention of malaria.

Question 30. Is There Any Advice For The Patient With Dengue Fever To Prevent The Spread Of The Disease To Others?

Answer :

The unfold of dengue from a affected person to others is feasible. The patient need to be included from contact with the mosquito. This can be done by using making sure that the affected person sleeps beneath a mattress-internet. Effective mosquito repellents are used in which the affected person is being provided care. This will save you the mosquito from biting the patient and from getting infected and spreading it to others. 

Question 31. What Is Your Advice On Travel If There Is An Outbreak Of Dengue?

Answer :

There is not any journey restrict. However, you have to be aware about what to do in case you are traveling a place where dengue has been said. This includes watching prevention measures described in these often requested questions and solutions and reporting to the medical doctor if you have fever and are worried that it is probably dengue fever.

Question 32. What Should The Doctors Treating Dengue Do ?

Answer :

Patients suspected to be suffering from dengue haemorrhagic fever or dengue shock syndrome ought to be admitted to a hospital straight away.The development of those sufferers ought to be monitored frequently at 1-2 hours c programming language.Platelet counts and haematocrits have to be monitored again and again to review the progress of patients.If the haematocrit ranges fall dangerously then a blood transfusion should be taken into consideration.

A fall of more than 20 % as compared to preceding levels can be an indication for transfusion. If the haematocrit values upward push the patient need to receive fluids intravenously and the fluids cautiously monitored to ensure that the patient does not get excess fluids. A upward thrust of greater than 20 % as compared to preceding stages may be an indication for IV fluids. The medical doctor should decide based on nice judgement of patient's circumstance.

Question 33. What Should The Doctors Treating Dengue Avoid?

Answer :

Do no longer prescribe aspirin and brufen or any other medicine that reduces the platelets or increases the tendency to bleed.Avoid giving IV fluids unless the affected person is bleeding or the haematocrit degree is growing regularly.Avoid speeding into giving blood transfusion except the haematocrit is falling dangerously. Do not supply platelet transfusion unless the platelet count is very low or unless there's bleeding.

Question 34. What Is Your Advice Regarding Reporting Of Dengue?

Answer :

All suspected or probably dengue cases should be reported to the health authorities. Further affirmation of the instances is completed by the fitness government. Seek their guidance on blood collection and transportation of samples from suspected/possibly instances of dengue.

Question 35. What Can The Community Do To Prevent Dengue?

Answer :

In reality, the community is the key to dengue prevention. As elaborated above, prevention of dengue is predicated closely on stopping the mosquito (Aedes aegypti) that transmits dengue from breeding internal and in the location of homes. Every family can undertake the very simple measures to prevent current water collections from turning into locations for breeding of A.Aegypti by using draining out water from diverse packing containers, by everyday changing of water plus cleansing flower vases and other gadgets or, within the case of unused items, through discarding/destroying them.

Since the mosquito does no longer journey a ways, "house cleaning" by using all participants of a network will ensure that no breeding places exist, stopping dengue from occurring. The most important approach in the prevention and manage of dengue is "source discount", or prevention of breeding places, referred to above.

Question 36. In The Case Of A Dengue Outbreak Or Epidemic What Are Our Strategies?

Answer :

Prevention of mosquito breeding locations stays our mainstay. However to forestall or to sluggish down the transmission it may be supplemented by way of "thermal fogging", the usage of fogging machines. In fogging,we use an insecticide that has a direct knock-down effect on adult mosquitos. When fogging is undertaken after a plague takes place, it's miles sadly too past due. Fogging, to be powerful, should be executed at about 3-4 days c program languageperiod. It is high priced and time ingesting. Therefore, measures undertaken by means of the network, for the community, to prevent the breeding of mosquitoes is far extra price-powerful than containment measures once a virus occurs.
