Earthquake Plans And Emergency Kits

By Eric Holm


Those who are wise enough to consider earthquake preparedness could find themselves in a better position to survive a natural disaster than others. Earthquakes are simply unpredictable, and they can strike at any time, anywhere in the world. More often than not, most will simply count on first responders, like police and paramedics, to be there for them if something disastrous happens. During natural disasters, these individuals may or may not be able to help, so taking steps to insure the survival of you and your family is a must.

The staples of every earthquake preparedness and kits are first aid supplies, medicines, and several gallons of drinking water and enough food for your whole family that will last for at least three days. You should also include gadgets and tools such as battery operated lights and lamps, transistor radio, and mobile phone or other types of communication device that will help you survive even when there is no electricity and gas.

Some people even recommend buying furniture-fastening straps, safety adhesive fasteners, and other implements that can keep your furniture, drawers, cupboards and other fixtures from falling off. Cutting tools and fire extinguishers must also be within easy reach so that you can cut off water and gas pipes and extinguish fire when it happens after the earthquake.

Every single family should discuss and develop a plan for when the unthinkable happens. Knowing what to do and where to go in an event such as this can be the difference between life and death. Sit down and discuss proper ways to protect yourself from falling objects and moving furniture. Make sure that everyone knows where the survival kits are as well. Another important piece of the puzzle is having a designated area where friends and family can meet up in the event that loved ones become separated. There may be times when staying in the home is not safe, so be sure that there is a back up plan that everyone clearly understands.

Disastrous seismic activities are quite rare, but your earthquake preparedness gear can also be used during other emergency and disaster situations. Just make sure that you immediately replenish your supplies after using them for other purposes. Also, do remember to check your kits every six to twelve months to replace stored water, canned goods and other food items, and medicines.

Choosing The Best Pocket Knife Sharpener

By Gwen Lowe


People own pocket knives for a variety of reasons. For some people it can be practical. If you run a business then you can often find yourself opening parcels, fixing things and generally dealing with a number of issues where having a blade to hand can be useful. If you enjoy camping then having a pocket knife can be very advantageous and could even be vital in some emergency situations. In order to keep your knives in a usable condition it helps to have the best pocket knife sharpener.

Over time the blade can become dull with more and more use. Fortunately rather than continually having to purchase new knives all you need to do is keep them sharp. What you use to keep the blades sharp will depend on the type of item you have and the material that it is made from.

When considering something portable a stone is best for something to carry around in your pocket. This allows you to sharpen the blade quickly. How often you sharpen it will depend on what you use the blade for. For example you may only wish to use it occasionally to cut string or open packages then you do not need to sharpen a blade very often. If however you go camping a lot and use it regularly then you need to sharpen the edge more regularly.

The best material for this is diamond. When you want the sharpest possible edge then you should sharpen along the edge of the blade. Alternatively you can use a stone that is coated with diamond paste in order to get a sharpened edge without getting something that is fully diamond in order to sharpen your knife.

Ceramic sharpening is another option. This uses a stick of ceramic material that comes in either blue or white. The blue is a coarse material while the white is smoother. The blue is often recommended for people who are using a sharpener for the first time as these can be used for general usage.

These are relatively simple to use. All you have to do is switch the device on, fit the knife to the machine and then let it do the sharpening before finally switching it off. It is often just a case of following instructions. However remember to check the size of the device and the type of blades it is compatible with to avoid damaging the handle or other parts.

The size of the sharpening product you use should be referenced on a website or product specification. A lot of reviews will often include product specification information so it is best to check this before placing orders. This will allow you to choose something appropriate to your requirements.

In short there are a number of options available when considering a knife sharpener. It is best to check a broad range of reviews and opinions. This will make it easier when finding the ideal option to suit your requirements. Use your regular search engine to find out more about different brands as well as getting feedback from customer reviews, social media and other forms of feedback to help find the right sharpener to suit your requirements.

How To Go About Training Golden Retriever Puppies

By Jaclyn Hurley


Golden retrievers are a popular breed of dogs. They are good looking and are quite intelligent. The breed is also popular because the dogs are very friendly and they show a lot of appreciation for human companionship. They are also good at taking instructions. The key is to start training golden retriever puppies as soon as they come into your care.

Golden retriever puppies can be trained without a professional trainer. It helps to start training right away when the puppy is still adjusting to its new environment rather than wait until it already develops habits and try to break them. Puppies aged at least 8 weeks old can take instruction.

Thanks to their friendliness, golden retrievers are easily trainable when training is done with affection. Affirming them with positive words and petting them lets them know that they have done a positive thing. They will do the action again and again to get rewarded again. Treating them with food is also a good way to reward them but minimally. This is one breed that packs on the pounds quite easily. Dogs should also not be trained to associate being fed with whether they behave or not.

You will find that these breed of puppies learn quite fast and they have the ability to learn a number of things at the same time. A good approach is to tackle the habits that the puppy comes with such as jumping, biting and chewing on things. These are not bad habits but the puppies need to learn what they can and cannot bite and chew on and bite.

Reinforce desired behavior by using words like no and off to remove them from furniture. Use a firm, if necessary high voice to get their attention and stop them from continuing with an undesirable action. Use the same stop words in the same tone and a happy, voice to praise them. Be consistent and the puppy will soon know the difference between actions that are good and those that are bad. Others in the household should have the same consistency.

During early days, you should teach your puppy to sit. The right place should help themselves should also be taught as early as possible. After several weeks of consistent training, there should be no messes on the carpet on the house. Stay close to the puppy and direct it outside whenever you see the leg going up. Quickly shoo the puppy outside and they will know they need to go outside when they need to go.

A puppy should also get used to being cleaned from early on. Get into a routine about washing them down with pet shampoo, drying them and brushing down their fur. You will be able to see the beginnings of any pests like ticks or any kind of infection or disease and take care of it before it gets serious.

A lot of dog owners fail to set aside the time it takes to properly train a golden retriever puppy. They then end up with an adult dog that is a problem rather than a joy. Start with simple lessons and then go on to more advanced ones. Getting a head start is also advisable because you will have time to bring in a professional trainer if necessary while the puppy is still young. Consistency will pay off in form of a well behaved, four-legged family member.

Exploding Nuclear Reactors vs Nuclear Weapons

“Aliens’ and your favorite mass media had it wrong. Nuclear Reactors do not explode like Nuclear Weapons for some very good, science based reasons. While still a major concern for a whole host of environmental and long term waste disposal reasons Nuclear Reactors are not really that high on a Terrorists targeting matrix. The attached article by a Penn State student simplifies the argument as much as possible. It is a quick read but essentially it is an Apples and Oranges argument.

Why a Nuclear Reactor Cannot Explode like an Atom Bomb

Jason Denhollander / http://www.personal.psu.edu/jdd5053/blogs/the_den/technical-description.html


Reactors and Atom Bombs
A nuclear reactor is a power plant, that uses nuclear fission to eventually generate electricity.
An atom bomb also uses nuclear fission to generate energy causing an explosion. However, due to
fundamental differences between the two a nuclear reactor cannot explode like an atom bomb. To
understand these differences, it is first important to understand the concept of nuclear fission and
criticality.


Background
Fission
Nuclear fission results when a neutron collides with an atom, causing it to become unstable and
split. Once the atom splits, neutrons are released, along with energy and radiation, this is shown below
in figure 1. In a reactor, the energy released is used to heat water. Eventually once the temperature of
the water is high enough, the water will change to steam. The steam is then forced through a turbine,
which creates electricity. Depending on the speed of the neutrons, a fission can be either a fast fission
or a thermal fission. Thermal fissions pertain to slower moving neutrons.
Figure 1. Fission Reaction
The concept of fission is the heart of the nuclear industry. In a reactor millions of fission
reactions are needed to generate the energy required to heat the water. Causing fissions over and over
again would not be an effective way to do this, instead a chain reaction is used. A fission chain
reaction is a fission reaction that sustains itself. When a neutron collides with an atom, more neutrons
are released. If there is an abundance of atoms, and the neutrons are contained, the neutrons that are
released from the first reaction, will cause more atoms to fission releasing more energy and more
neutrons. The number of neutrons present after each fission is the criticality of the reactor and is
denoted by the multiplication factor k.
The Multiplication Factor and the Six-Factor Formula
The multiplication factor, k, is simply the number of neutrons produced per fission, divided by he number of neutrons lost per fission. The six-factor formula is composed of six factors that when
multiplied together equal k, k = η f ε p PTNL PFNL . Each term represents a different way a neutron can be
lost or gained.
• η - Production Factor. The production factor compares the number of neutrons produced to the
number of neutrons being absorbed. It is dependent on the type of fuel being used.
• f - Thermal Utilization Factor. The thermal utilization factor compares the amount of neutrons
being absorbed by the fuel to the amount of neutrons being absorbed everywhere else.
• ε - Fast Fission Factor. The fast fission factor compares the total amount of fissions to the
amount of thermal fissions.
• p - Resonance Escape Probability. The resonance escape probability is the probability that a
neutron survives the resonances as it slows down from a fast neutron to a thermal neutron.
• PTNL - Thermal Non-leakage Probability. The thermal non-leakage probability is the probability
that a thermal neutron will not leak outside of the core.
• PFNL - Fast Non-leakage Probability. The fast non-leakage probability is the probability that a
fast neutron will not leak outside of the core.
Figure 2. The neutron life cycle
Figure 2 shows the neutron life cycle, which is simply the terms of the six-factor formula. Once
the multiplication factor is determined, the criticality of the reactor can be found.
• k > 1 --> supercritical, more neutrons are being produced than lost.
• k = 1 --> critical, the same amount of neutrons are being produced as lost.
• k < 1 --> subcritical, more neutrons are being lost than produced.
The criticality of a reactor is a crucial design element. A subcritical reactor is useless since it
will be impossible to start a fission chain reaction. While a critical reactor is the most desirable,
reactors are normally designed to be supercritical, and then through the use of moderators, are scaled
back to critical. Now that fission and criticality are understood, it is easy to see the differences between
an atomic bomb and a nuclear reactor.he Differences
There are two main fundamental differences between the design of an atomic bomb, and the
design of a nuclear reactor. One difference is the way the fission reactions are controlled and the
second difference stems from the enrichment of the fuel.


Control of Nuclear Fission
One main difference between the two is that the fission events in a reactor are monitored and
controlled closely. An atom bomb is an uncontrolled fission chain reaction, that releases exorbitant
amounts of energy quickly. The design of a nuclear reactor includes control rods. The control rods are
placed in the core to control the fission reaction. Control rods do this by absorbing neutrons, which
decreases the multiplication factor. The more control rods in the core, the lower the criticality, thus
there will be less neutrons available for fission. An atom bomb is designed to maintain all the neutrons
produced, making it always supercritical.


Enrichment
The second difference between the two is the enrichment of the fuel. Natural uranium, the
uranium found in the earth, cannot be used as a fuel because it is not reactive enough to cause a chain
reaction. This is because natural uranium is composed almost entirely of U
238, which is a relatively
stable element. By enriching it with U235, the uranium becomes more reactive, which increases the
production factor. While both fuel for a reactor and fuel for an atomic bomb are enriched, a reactor's
fuel is only enriched around 4 to 5 percent. Whereas an atomic bomb is enriched to about 90 percent.
This makes the multiplication factor much larger in a bomb than a reactor, which signifies a greater
number of available neutrons. The fuel used in a reactor is not capable of causing an explosion.


Explosions
While a nuclear reactor can never explode like an atomic bomb, an explosion can still occur.
All power plants are a potential site for an explosion, because the fuel used, whether it is coal, uranium,
or natural gas, needs to be energy dense. At coal plants, sparks can set coal dust on fire causing an
explosion. Gas leaks can cause explosions at natural gas plants. Typically at a nuclear reactor, the type
of explosion seen would be a steam explosion. A steam explosion could only occur if the reactor
suffered a meltdown. A meltdown means that due to lack of coolant, or too much fission, the core
becomes so hot that it melts. Due to the intense heat produced, water is turned to steam. Also, the fuel
rods melt, turning them into a liquid. This allows the metal to react with the steam, causing an
explosion.


The destruction at Chernobyl was caused by a steam explosion. Since the turbine feed valves
were closed, the steam in the core had nowhere to go. Then, the pressure in the core did not increase,
causing even more steam to be created. When the reactor core began to meltdown, liquid metal
touched the steam, causing an explosion. The explosion caused the roof of the core to lift off, exposing
the core to air. The air reacted with the graphite moderator in the core, resulting in the production of
carbon monoxide. Since carbon monoxide is flammable, it caught fire due to the extreme heat in the
core. The fire burned for days.

Conclusion
Even during the worst accident in the history of nuclear reactors, an explosion like an
atomic bomb did not occur. This is because the fuel and design of a nuclear reactor do not allow the
fission reaction to become uncontrolled making it impossible for an explosion like an atomic bomb to
occur.
