Paralegal Jobs

-


Paralegals are found in all types of organizations, but law firms, corporate legal departments, and various government offices employ the greatest number of paralegals. There were about 238,000 paralegals at work in the United States in May 2006. Private law firms employed 70 percent of paralegals and legal assistants; the rest generally worked for corporate legal departments and at various levels of government.

Employment of paralegals and legal assistants is projected to grow 22 percent between 2006 and 2016, much faster than the average for all occupations. This is because employers are trying to reduce costs and increase the availability and efficiency of legal services by hiring paralegals to perform tasks once done by lawyers. Learn how many paralegal jobs are available in your area.

How to Become a Paralegal

The most common way to become a paralegal is through a community college paralegal program that leads to an associate degree. Another common method, mainly for those who already have a college degree, is earning a certificate in paralegal studies. A limited number of schools offer a bachelor’s and master’s degree in paralegal studies. Some employers train paralegals on the job.

Associate and bachelor’s degree programs usually combine paralegal training with courses in other academic subjects. Certificate programs vary considerable; some take only a few months to complete. Most certificate programs provide intensive paralegal training for individuals who already hold college degrees.

About 1,000 colleges and universities, law schools, and proprietary schools offer formal paralegal training programs. Approximately 260 paralegal programs are approved by the American Bar Association (ABA). While many employers do not require such approval, graduation from an ABA-approved program can enhance employment opportunities.

Demolition

Introduction

Taking down old buildings and replacing them with new is a process that has been going on for thousands of years. The destruction of buildings might have occurred during battles or attacks on communities; or due to natural disturbances such as earthquakes or volcanic activity. The resultant ruins would need to be removed and rebuilt. So the idea of demolition would have come about where a population wished to re-inhabit a specific area or site. (One famous example is the Holy Temple in Jerusalem which was deliberately destroyed by the Assyrians around 586 BCE. After 50 years of occupation the Jews returned to Jerusalem and began the re-construction of the second temple which took seventy years to complete.)

However the actual word to demolish only came into being in 1570, and was used from then on to mean the deliberate taking down or destroying of a building or structure.

Preserving the past - preparing the future.

In a country like Britain with very dense populations per square mile, there is a limited amount of land available for construction. The land between built up areas of the villages and towns is known as Green Belt and is protected from development to preserve the agricultural and natural heritage which is vital to the economy of the country.

The outcome of this policy is that there is a constant shortage of land for housing and industry, so the developers have to be more creative when providing structures for the population. One of the ways of doing this is to find places where the buildings are no longer commercially viable or have been abandoned, and re-use the area for different purposes. These areas are known as brownfield, or greyfield sites. In some cities, particularly Leeds and Manchester, the old warehouses or factories have been converted into apartments, retaining the original shell and reconfiguring the internal dimensions into valuable living accommodation.

Brownfield sites are disused industrial and commercial facilities where the land may be contaminated with hazardous waste or pollution. They are potentially valuable for significant redevelopment once they have been cleaned up. Greyfield sites are urban properties that have been underutilised or abandoned, but do not have the environmental issues of brownfield sites. They were termed greyfield sites because of large areas of asphalt that covered the land. These sites are valuable because they already have the infrastructure such as water, sewage, electricity and gas in place and do not need remedial work to utilise the site.

When a structure is to be removed there are different ways of approaching the task. The size and construction of the building, the new use of the site and whether there are valuable elements suitable for re-use, will all determine how it is to be demolished.

Traditional Demolition

Traditionally, once all the services were disconnected, the machinery and men would go in and just knock down the walls which caused the roof to collapse and then drag all the remains away. Any concrete hard standing would be broken up ready for removal. The site would be cleared of rubbish and disposed of in landfill sites. However modern demolition practices are very controlled and are subject to strict planning, safety and monitoring regulations.

Small structures such as two or three storey houses can be dismantled quite easily with hydraulic excavators and bulldozers using an undermining process. The walls are undermined at the base, in order to topple the structure; at the same time the manner and direction of the fall is controlled. Clean-up and safety issues are also taken into account when deciding how the building will be undermined and demolished.

Larger buildings such as tower blocks and chimneys require more specialist techniques, and are outlined below.

Deconstruction

A new approach to demolishing buildings is deconstruction - a green approach. The aim is to reduce the amount of waste going to landfill sites by carefully preserving valuable materials for reuse. The work may be a painstaking task of dismantling by hand - brick by brick - or beam by beam. The reclaimed materials are then recycled or re-used for future buildings. The results of deconstruction can save in excess of 90% waste from going to a landfill site. When the farmer opposite to my house sold his farm yard with barns for housing, the builder demolished the barns, cleaned up the bricks and reused them for the perimeter wall of the farmhouse. At the time I was looking for some rubble as a base for a path and the builder let me take several barrow loads off his pile.

Recycling

Historically when old buildings were ruined from disuse or war damage the local people would gradually remove the stone and use it to build their new structures such as houses or barns. Hadrian’s wall between Carlisle and Newcastle has mostly disappeared because after the Romans left, the local population made off with the beautifully dressed stone the Roman craftsmen had used in the building of the wall. So even in those days people understood the value of recycling because it was much cheaper than having to quarry and dress the stone themselves.

At one time the rubble resulting from a demolished building would be taken to a landfill site for disposal. Now however concrete can be rapidly broken up with the latest machine called a guillotine and the resultant rubble can be crushed and used as sub-base material for the foundation of the new building which is to replace the old, or sent to other construction sites. These days this crushed rubble is called 6f2 crushed stone or 6f2 crushed material.

Modern machinery and techniques allows the demolition companies to efficiently segregate waste types on or off-site. Wherever possible construction materials are recycled and re-used in the new structure. Recycling of waste contributes to a significant savings in project costs and is good for the environment.

When we renovated our bungalow 20 years ago the builder, who was a bell ringer, found an old beam from a bell tower that was being renovated, and after carefully treating it, installed it in the kitchen. It gave the room some badly needed character and has never needed any further treatment.

Copper pipes, wiring, roof tiles or slates, floor tiles and doors, and wood panelling are some of the valuable items that are saved for recycling and re-use. There are specialist yards in many towns where reclaimed old or antique artefacts are available for purchase.

Tall Buildings 

The demolition of tall buildings requires expert techniques. In some cases a wrecking ball on a crane may be used to demolish the top part of a tall building until it is down to a manageable height. However this process is rarely used due to the uncontrollable factor of the swinging ball and the proximity of other buildings.

Other methods of demolition of tall buildings are by implosion using explosives, controlled collapse and piecemeal. Also ‘High Reach’ demolition excavators are used where explosives are not appropriate. Once the building is down to a more manageable height demolition continues in the usual way. 

The steeplejack Fred Dibnah became famous in the late 1970’s for his work on demolishing tall chimneys without the need for explosives. He would cut an ingress at the base of the chimney, use wooden props to support the brickwork and then burn the props so that the chimney toppled hopefully in the right direction.

The tallest building to be lawfully demolished was the Singer Building of New York in 1967/8. More recently the collapse of the World Trade Centre after the 9/11 attack in 2001 illustrates the terrible devastation that could occur if the demolition is not controlled and very carefully contained.

In the demolishing of tall buildings and large structures water hoses and spray equipment is used to control the dust and would is termed a wet demolition.

Explosions 

What comes to mind for many people when they think about demolition would be the dramatic collapse of a tall building using explosives. However it is usually the process of implosion, using explosives, that brings down a tall building so that it does as little damage as possible to the surrounding environment. Implosion is essential for dense urban areas and is very fast, the collapse taking only seconds, with the building dropping inwards into its own footprint.

Using explosives is specialist work and is a very skilled process and getting it wrong can be devastating. If an implosion is not prepared correctly the danger may be damage to neighbouring structures or even killing onlookers from flying debris. Even more dangerous is a partial collapse of a building where the remaining structure is unstable and there are still primed explosives that failed to go off. Workers are in great danger if or when continuing the demolition.

Other dangers of working with explosives occurs when the atmospheric pressure from low cloud above the implosion site will cause the shockwave to spread outwards instead of upwards. The wave of energy and sound created will break windows and cause other damage to the surrounding buildings.

Because of the dangers of working with explosives, implosion will only be used when other methods are too costly or impractical.

Health and Safety

Demolition of any building is highly dangerous and is a much more complicated and technical process than most people would realise. Experienced and skilled operators are essential to ensure safety for both workers and public alike. The stability of any structure is reliant on the interdependence of its component parts, so an incorrect sequence of dismantling could result in an accidental collapse.

Health and safety is paramount in demolition work so personnel working in the industry have to be appropriately trained. It is advisable for operatives to have gained a Certificate of Competence in Demolition to ensure they have the necessary skills and safety awareness. All demolition work is regulated by the Construction, Design and Management Regulations.

Sequence of Demolition

There has to be a sequence of actions before any demolition can take place. Each area council will have their own specific list for planning approval, but a typical order would be as follows:-

  • Provision of Information
    The demolition company must provide information about the construction to be demolished, its previous use and the appropriate demolition method to be applied including disposal of hazardous substances.
  • Survey of Demolition
    Identification of any structural problems as well as risks associated with hazardous or flammable substances will require a thorough survey of the site. (E.g. Where petrol has been stored, ie disused garage, precautions need to be taken to prevent a fire hazard).
  • Preferred and Safe Method of Work
    A reputable company involved in demolition will be able to select the appropriate method of disposal. Planning and outlining the dismantling process is necessary for assiduous monitoring. A detailed statement outlining the safety process needs to be agreed by all parties involved before any demolition can take place.
  • Preparation and Planning
    There is a lot of preparation to be done before starting work on demolishing the building itself. Issues such as asbestos abatement, disconnecting utilities, rodent baiting, dealing with hazardous substances and making safe any electric, gas or other services have to be resolved.
  • Protection of the Public
    Where demolition is carried out in heavily populated areas the protection of the public is paramount. Safety cannot be compromised. Temporary services may need to be arranged, health hazards assessed and people disturbed will need to be informed.

Conclusion

The word ‘demolish’ is interpreted as the deliberate and controlled collapse of a structure. Demolition work is a very dangerous business and demolishing any building is a complex and skilled process. The aim in demolition is to remove an unwanted building as safely and quickly as possible, recycle or re-use most of the old material, and clear the site ready for the subsequent use.

In the centre of Nottingham over the last few years there has been a major reconstruction of what was an old car park into a brand new shopping centre. While this was going on the public were only really aware of the boarding around the area, a change in traffic direction and maybe some big lorries going in and out of the site.

So the next time you see buildings being demolished to make way for the new, give a thought to the company involved who’s team are daily working in a dangerous environment, adhering to all of the regulations and carefully and meticulously carrying out the project to bring us the modern conveniences we have come to expect and clearing the way for the future.

If you have ever suffered from Sciatica or Sciatic Nerve problems you will know how uncomfortable and painful this condition can be. Sitting to eat dinner, driving the car, even sleeping can be greatly affected by sciatic pain and unlike many other joint or muscle problems it is simply not possible to isolate and immobilize the affected area until your body has had a chance to heal itself but if you follow these couple of tips you will have the best chance at keeping your sanity!

Accurate Diagnosis of your condition - The first thing is to get an accurate diagnosis of why you are in pain. Often times sciatica is caused by muscle tension or imbalances which can directly affect the discs and vertebrae in your back which results in a irritated sciatic nerve. Other ’structural’ problems with your spine can also cause this irritation and that is why an accurate diagnosis is essential for finding the best treatment.

Heat and Cold Packs - many people report gaining relief through the use of heat and cold packs particularly where the problem lies with increased muscle tension. Alternating between both hot and cold packs on the affected area has also been reported as a good pain reliever. The hot pack promotes blood flow and can release tensed up muscles and the cold pack helps in reducing the amount of inflammation so you are getting the best of both worlds when alternating between the two.

Physiotherapy - this is something that I have not had any success with in dealing with my sciatica, however combined with the right exercises and assuming that your condition is suitable to be treated this way there is no reason not to give it a go. Many doctors see physiotherapy as the first step to easing the problem and once again the blood flow in and around the muscles and loosening of joints may be beneficial to you.

Anti Inflammatory/Pain Relieving Medication - No doubt one of the most important steps to easing your sciatic pain is to reduce any inflammation of the offending area and of course to limit your pain so you can get on with life. Unfortunately this is where the use of NSAID’s or non-steroidal anti inflammatory drugs is the road most doctors take. Sure, they may ease your pain and reduce inflammation but if you had any idea of the unwanted effects these drugs can have on you I’m sure you would think twice.

Many back pain and sciatica sufferers are forced to use these drugs long term, previously myself included, as most back complaints are not easily or quickly resolved. This long term us of NSAID’s can have lasting effects on your health. Problems with kidneys, the liver, the intestines and the stomach lining itself are not uncommon and of course add to this the noticeable side effects like cramping, headaches and drowsiness just to mention a few.

So how do we protect ourselves against these problems while still getting the pain relief and reduced inflammation that we need? The answer is natural medicines that do the same job without jeopardizing our future health. There are many great all natural products on the market these days and for peace of mind there really is no other choice.

Give your body a break! For more information on the best all natural pain relievers and anti-inflammatories please head on over to Back Pain Products and check out the all natural Heal N Soothe. Your body will thank you for it!

 

Getting The Crowd Into Your Trade Show Booth

-


Getting the proper crowd into your trade show booth can be a big task, but not impossible.   Walking the trade show floor on numerous occasions  I have noticed that there are some impressive looking trade show displays and some just mediocre.  I have also noticed some of the nice impressive booths have no crowd in them. Attendees just pass them by as if they were not there. The booth looks relatively nice with decent product displays yet no visitors to the booths (as a matter of fact I have seen some exhibitors which are the powerhouse of their market without any crowds in there booth at all) this means no new clients and also they may have gotten to be a powerhouse by other means, definitely not by displaying at trade shows. What makes the difference in attracting attendees into you booth?   There are a few factors

1- In getting attendees into your both first of all you must have a friendly and inviting trade show display, this mean do not configure your trade show booth like a forte.  It should be open and inviting -one should not feel trapped once they enter your booth.

2- Greet attendees in the trade show aisle not in your booth, Very few  will ever freely enter your trade show booth without being invited

3- To capture attendees’ interest you must have something different from the rest of exhibitors. Try to create some sort of theme or major attraction inside your trade show booth. This will serve as a major draw for show attendees. Your trade show booth might be nice looking but still unable to entice the crowd, therefore, a crowd pleaser is a must. I  have seen this happen at a recent show, true the attendance was down at the show but all in all most exhibitors said they did better that the previous year or show , why?. Fewer exhibitors mean less competition for you the exhibitor. This in turn turns into leads which eventually can result in sales.  In getting the best out of your trade show you must have something unique different from the rest of exhibitors. DO not use gimmicks they only work but for so long, be creative about your product or the imagery of your booth…always introduce a theme whether in the appearance of the booth itself, your product or the actual displaying of the products themselves… be creative intelligently and forget the gimmicks

To recap your trade show booth should be inviting and open. One should be able to enter your booth not feeling trapped.  There should be some sort of theme to your booth and show something that is different from the rest of show exhibitors. To seek  professional help with this please contact ELDS, INC at (626) 969-3399

Iceland is now affordable for Americans

-


The global financial crisis has not treated the normally expensive island nation favorably, to say the least. However, there are opportunities in the current situation and the considerable devaluation of the local currency has created rates that are extremely favorable for tourists and serious investors.

Many contractors and property- and automobile owners have been forced to raise cash fast as a result of the crisis and this has created some fantastic opportunities for buyers who can raise a deposit from their own funds. For those who want to travel to Iceland to enjoy the unique nature and explore investment opportunities at the same time one option is to take advantage of the over-abundance of cottages in Iceland that are for sale and rent at very reasonable prices. A new website for english speaking audiences, IcelandForSale.com, has been opened to help facilitate the buying and selling of properties, automobiles, heavy equipment and other assets at exceptional discounts.

The current exchange rate means that your purchasing power is over 70% better than it was 1 year ago. Foreign investors are buying cars and real estate left and right. Auto loan companies are reclaiming cars and heavy equipment and shipping them to other countries for sale. Foreign currency loans for properties in Iceland have more than doubled while property values have plummeted by as much as 30 percent forcing some desperate homeowners to pay black-hat dealers up to USD 25.000 to relieve them of their loans and mortgages so they can make a fresh start. They use disposable LLCs to buy the houses, pocket the money and allow the companies to go bankrupt.

Ten days after the króna plummeted, Iceland’s tourist board, airlines and tour operators launched a coordinated campaign of low fares and airfare-hotel packages to lure Americans. Signs in the airport welcomed arrivals to Half-priceland.

Effective Guide to Shop for Girls Bedding

-


I will be the first to admit it. I am a person that literally know nothing about girl bedding. Since my sister recently had a baby girl, it is time for me to learn. One of the many items on her registry list is a nice, high quality, and expensive girls bedding set. She specifically mentioned a brand called Olive Kids Flowerland bedding. I personally have never heard of them before. After a few moments of the computer, I found out that they are the manufacturer of some very cute and fancy kids bedding, kids room decor, and also the kids play furniture.

As I began browsing the Olive Kids website, I was overwhelmed by the number of choices of designs available. Just by looking at the girls bedding sets alone, it ranges from girls princes bedding, ballerina bedding for girls, to girls butterfly bedding. While they all look very similar to my untrained eyes. I am sure my sister will have a different opinion.

So the next thing I did was pick up the phone to call my mother. After all, mom knows everything. After a previous conversation with my mother I found out that my sister is decorating her room with a fairy theme. Unfortunately Olive Kids do not specifically call for a girl fairy bedding design. So I will need to look elsewhere for that. After a few more minutes online, I was able to locate a number of websites that have girls fairy bedding. I was very happy about that. I bought it and it is now done.

Finding the Best Nintendo Wii Price Today

-


Nintendo Wii prices don’t really seem to fluctuate. They change depending on if they are in a bundle package or if they are used. Otherwise expect to pay the full Nintendo Wii price. Great places to find a Wii are your local Best Buy, Target, Walmart and Toys R Us. You can simply call these stores and find out if they have any special such as any coupons towards the purchase or a free game with a Wii purchase. If you do want to purchase in a bundle then look at those prices as well. Buying used will give you many more options.

Finding the best Nintendo Wii price today isn’t as easy as one might think. There are lots of packages you can purchase that includes a set of games, the Wii and a controller that really give you the best deal but may not be what you are looking for. Trying the suspect Wii vendors may come with better warranties, but perhaps the best deal might be from your local craigslist?

When deciding to purchase a Wii one must also figure out whether they will need an extra controller or any particular games. Especially during the holiday season Best Buy, Sam’s Club, Target and even Walmart will have bundle deals with an extra controller and two or three games for a price that doesn’t even sound like the down-payment on a car. Now if you were thinking that you can find a friend who works at one of these stores to buy the game console for you I’m going to disappoint you by telling you that these stores don’t give any discount for the game consoles to their employees. You can tear up that Best Buy application.

The cost of the Wii is $250 plus taxes. Or you can get a bundle that comes with 2 remotes and 3 games for about $550. It really just depends if you are planning on using the games offered in the bundle. Call your local Target, Walmart, Toys R Us, and Circuit City in the mornings to see if they even have the Wii in and to find out the Wii prices. Sometimes they are difficult to locate. The best thing about purchasing the Wii at Best Buy is that they offer a warranty plan on their electronics that extends past the warranty that Nintendo offers.

Now I know that some people find offense to purchasing items online but if you aren’t one of those people then great! You can purchase the Nintendo Wii through any trusted 3rd party seller directly at Amazon or EBay. Sometimes you might even be able to purchase one at less than the original store price. But I would be weary of used consoles. If something does happen then you are out of luck and if it is delivered and it is broken it may be difficult to get a refund from a seller in China. Sometimes you can find the Wii at game stores as well.

If you do want it for less consider signing up for a Best Buy card and getting the discount they offer you once you open the account. This may be the cheapest new route for Wii prices. If you don’t mind a used Wii then go out to the pawn shop or look in the paper. This way you can actually see if the console works before purchasing it. Used systems are also sold at EBgames or Gamestop. Used consoles would also be on craigslist. Wii prices are usually still high because it is a popular console. If you go to the game store you can even sell your old console or games and use it as credit towards the new Nintendo Wii. Good luck in your search for the best Wii price.

Air cooled water chillers

-


Air cooled water chillers are vapour compression refrigeration systems. The main components of a vapour compression refrigeration system are the compressor, condenser, expansion valve & evaporator.

Vapour compression refrigeration systems have a refrigeration cycle. The cycle starts with a cool low pressure mixture of liquid & vapour refrigerant entering the chiller evaporator. Once inside the chiller evaporator it absorbs the heat from the relatively warm water or fluid that the fluid chiller is cooling. This transfer of heat boils the liquid refrigerant in the chillers evaporator and the super-heated vapour is pulled into the chillers compressor.

The chillers compressor compresses the refrigerant to a high temperature & pressure, high enough to allow the chillers condenser to give up its heat to the cooler ambient air. Within the chillers condenser, heat is transferred from the hot refrigerant to the relatively cool ambient air this reduction in the chillers refrigerant causes it to de-superheat and condense into a liquid, then further sub-cool before leaving the chiller condenser.

The high pressure liquid refrigerant then enters the chiller expansion valve causing a large pressure drop across the chillers refrigerant circuit. The pressure reduction causes a small portion of the refrigerant to boil off, or flash, this would be seen in the chillers site glass. The site glass indicates if the chiller is short of gas, if the chiller is short of refrigerant gas the flashing inside the chillers site glass will increase. The boiled off refrigerant helps cool the remaining refrigerant to the desired temperature before the mixture enters the chiller evaporator to start the cycle again.
