Welcome to this first part of a four-part series on asthma, where we aim to understand what it is and how it can be managed.
Asthma is a chronic lung disease that causes inflammation and narrowing of the airways in the lungs. Recurring periods of wheezing, chest tightness, shortness of breath, and coughing are all hallmarks of asthma.
Asthma affects people of all ages, but most often starts during childhood.
Asthmatics have inflamed airways in their lungs. Inflamed airways are narrowed and very sensitive, thereby reacting very strongly to inhaled allergens.
When the airways react, the muscles around them tighten, narrowing the airways causing reduced airflow into the lungs. The swapping can and will progress, farther narrowing the airways. Associated with this process is the increased production of mucus, a thick, sticky fluid that farther narrows the already narrowed airways.
These reactions result in the symptoms of asthma – Wheezing, chest tightness, shortness of breath, and coughing.
Asthmatic symptoms are often mild and spontaneously resolve or are easily treated with minimal treatment. However, in some cases, it can progress and become worse, resulting in what is commonly known as an asthmatic attack.
Here, treating symptoms of asthma early is paramount. By the time an asthmatic attack ensues, emergency care is required and if left untreated, asthma can be fatal.
There is no cure for asthma. However, with proper and thorough ongoing treatment, asthma can be managed and sufferers of asthma can and will continue to lead normal and active lives.
Populations At Risk
Most often, asthma starts during childhood but it can affect all ages.
Young children who frequently suffer from respiratory infections are at the highest risk of developing asthma. Other risk factors influencing the development of asthma include being atopic (having multiple allergies), eczema, or, as mentioned above, having parents who are also asthmatic.
Boys have a higher risk of developing asthma compared to girls. However, once adulthood is reached, there are more female asthmatics compared to their male counterparts. As a sum total, most people with asthma have allergies.
Another significant population with asthma are industrial workers who come into contact with chemical irritants or industrial pollutants in their workplace. This population develops occupational asthma, a contentious disease label.
Causes of Asthma
A multitude of causes for asthma have been documented so far. These include:
- Genetic causes, especially atopic individuals or asthmatic parents
- Childhood Respiratory Infections
- A multitude of airborne allergens have been implicated
Signs and Symptoms of Asthma
Common signs and symptoms of asthma include:
- Chest tightness
- Shortness of breath.
Coughing caused by Asthma is often worse at night, disrupting sleep. Wheezing is a squeaky, whooshy sound that is audible with each breath. Chest tightness and shortness of breath can and is often confused with cardiac causes and can result in undue stress to the patient.
Having one or more of the above symptoms do not automatically diagnose asthma. Proper lung function tests, history taking and a physical examination by a health profession is the only way of confirming asthma.
The type and severity of symptoms of asthma treated by the patients although determines the management of the disease. Because symptoms vary over time, asthmatics need to be aware of their own symptoms and fluctuations thereof, and seek treatment early because while mild symptoms can be simply annoying, severe symptoms can seriously limit daily routines and exercise, and very severe symptoms can potentially cause death if untreated.
Treatment is now available to prevent the sunset of asthma in known asthmatics.
Triggers Of Asthma
- Allergens – dust, animal fur, cockroaches, mold, and pollens from trees, grasses, and flowers etc.
- Chemical Irritants – cigarette smoke, air pollution, chemicals, workplace dust, sprays etc.
- Medicines – NSAIDs (eg aspirin) and B-Blockers (eg atenolol).
- Upper respiratory infections
- Physical activity – exercise can trigger asthma.
This list is not exhaustive. Each asthmatic is unique and it is best if you seek advice from your health professional.
Prevention Of Asthma
Asthma can not be cured. But you can prevent it. Following these simple steps will go a long way in managing asthma.
- Educate yourself about asthma. Empower yourself.
- Have an Asthma Action Plan and follow through with it.
- Follow your physician's medicine regime
- Identify the triggers that cause your asthma and avoid them
- Document progress of your asthma
- Regular visits to your treating physician
In the next part of this series, we look at what to prepare and expect during a medical consultation.

So your looking for a place to watch new movies online? You want to watch all the newest releases in high quality right? You also want to watch them instantly and easily? Am I right? I though so! The internet has tonnes of sites that allow you to watch new movies online but as with everything on the internet, there are a lot of scams and the movies you do find are either poor quality or in a hundred parts! So how do you find a decent site to watch all the new movie releases on?
Firstly, you should always avoid the torrent sites. The files on these sites are full of viruses and spy ware that can damage your computer even if you’ve got anti-virus software. You should also avoid searching for new movies on You tube and other video sharing sites. You will almost never find full, good quality movies on them. So where should you go?
You can join a paid movie download price for a small one time fee. The fee is usually about the price of one movie in the shops (maybe a bit more) and you get access to huge databases full of the latest movies all ready to download quickly and easily. But when choosing a service to join there are a few things you should bare in mind.
Firstly, make sure that if your paying to join a site, they have a money back guarantee. You can never be sure what a service is like until you’ve joined and a money back guarantee is a sure fire way to make sure your not getting scammed. The best sites I’ve seen have an eight week money back guarantee with no questions asked.
Next, you should choose a site which not only has a huge selection of movies but TV shows and music as well. If your paying to join a service you should get the most out of your money! You should also choose a site that has customer support. The best sites I’ve seen have 24/7 customer support in case you have any problems or questions you need answering.

Today, the eBook reader is ubiquitous. You have the iPad, the Kindle, the Nook, Sony eReader and a host of others. There is an ongoing war between all of these the eReaders for market dominance and kind of set the stage for which one becomes the dominant player in the market. This war has moved into the classroom and the device that becomes accepted as the ideal gadget for the classroom will definitely become the cash cow for the company that owns it. Below are some of the devices that could someday become a part of every students backpack.
Amazon has different varieties of the Kindle that are targeted to different demographics with different price points. The idea is to have a Kindle that will appeal to every segment of the market. Depending on the type, it can hold approximately between 1500 to 3500 books. It can wirelessly connect to the internet and download books. The Kindle can download word documents and PDF wirelessly and so far has been the Jewel of Amazon. It has sold well and a lot of people are happy with its functions.
The Nook is the eReader from Barnes and Noble. Like the Kindle it can also hold about 1500 books, has an excellent color touch screen that is easy on the eyes, and you can download books in seconds to your Nook. It has a unique future that allows users to be able to swap books with friends or with a network they belong to such as a book club.
The Nook also functions as an mp3 player and can be used to listen to audio books. Other futures the Nook has include making notes, highlighting pages, marking text on your pages as you read and looking up words.
The iPad is a major game changer in the area of eReaders. With the launch of the iPad Apple put a wrench in the market for other eReaders. It is a full computer that comes as a light and flat gadget. It has a large touch screen color display, a virtual keyboard and a very user friendly interface. When you are reading a book or magazine, the display is very book like and you can actually flip the pages on the screen as you would on a physical book.
Apple has had a long relationship with education as its earlier computers like the MAC have more or less become the standard in schools for decades. They have a huge advantage over other eReader in that this product can easily sync with a student’s PC in a plug and play manner. Apple also has the advantage of the iTunes, which is a platform where books, magazines, videos, music and lectures can be easily downloaded.
This gadget connects easily to Apple App store, so that Apps available for the iPhone can be used for it. A good example is the iBook App which is the application that makes it possible for the iPad to function as an eReader. It is predicted that in the next few years, due to its cross functionality as a full fledged personal computer; the iPad will be what will be found in most students back pack.
Carrying textbooks to class each day is one of the biggest problems that students face. With the iPad, more than a truck load of textbooks can be stored in the form of eBooks, freeing up space in the students backpack and preventing back strain. The environment will also benefit as fewer trees will be chopped down to make textbooks and the issue of storage for outdated books will cease to exist.

For some people, the computer itself could be a scary topic, considering the fact around how complicated the machine is. Talking about computer networking could give a heart attack to such people. However, it is not as scary as it may sound.
Computer networking could be understood by separating the two words in the term. A “computer” as we know is a complex machine that helps us to process information. “Networking” refers to linking or connecting. Hence computer networking would simply mean getting two or more computers connected. When we say the word “connected” in this reference, we mean that one computer could be accessed through the other.
Broadly speaking there are two ways of connecting two or more computers. The first one is called the wired network and the other one is called the wireless network. Both of these are huge subjects to study and understand. However, in layman’s language it could be said that when two or more computers are connected through wires it’s called the wired network. And when they are connected without the wires through wireless router, it is known as wireless network. As the wired networks are limited to the area wherein the wire web is installed, similarly the wireless has range limitations. The number of machines that are on a network would ensure the speed of the network. More machines in a network would mean a slow network.
The various computer network systems could be – Personal Area Network; Local Area Network; Campus Area Network; Metropolitan Area Network; Wide Area Network; Global Network and most importantly internet, intranet or the extranet. The names are given to the network depending upon the arena they have. Like for example the campus area would mean the machines that are in a given physically limited campus are connected through the computer networking. This could be wired or wireless networking.
Internet could be understood as a global network system.

When it comes to our computers we want them to be in tip-top shape. We all want them to load web sites at the fastest times possible. Let's just face it; we demand the technology to be faster and faster because in our lives we are so busy we do not have the patience to be inconvenienced in the simple tasks like pulling up a web page really quick. This means that we want our machines to run like they should with no problems and start up in a reasonable amount of time. We can do everything that is in our powers to achieve this like: do all our computer maintenance properly, keep our updates current, remove old unused programs, and defragment the hard drive properly. Still when using our computer to surf the internet we seem to still have a slow computer from time to time when going to specific sites. Why? How can we do everything right and in our powers and still have a computer that lags with simple computations like pulling up a web page?
Well first thing is first. You need to understand that it is not your fault. There are just some things that we do not have control over in how our computers run when it comes to the internet. There are many, many other factors involved when we depend on the internet to deliver the exchange of information to us. These are uncontrollable factors like: the Internet provider, provider technologies used, programmers, servers, and security. Many things can contribute to the reliability of your computer and we need to understand probably one of the most frustrating ones, the web site itself.
Without getting to depth with details and abbreviations that would leave us saying "Wait come again", generally speaking the main contribution to our slow computer is the way the individual web site is designed and laid out. When programmers write web sites sometimes the site gets very confused with ads, links, headers, information, news, titles, images so on and so forth. All of this information is data that our computers have to download and process. Again we see a direct relationship the more that our computers have to download the longer it can take for our computer to open the page. When we go to one of these sites that is jammed packed with information that is clustered and busy we tend to see the site size almost triple from the average site size. With new ideas in how to build web pages more efficiently and new techniques used in our most common sites the load times are improved. The general rule of thumb stands that the more on the site: images, information, videos, flash pictures, etc. The longer the site will take to load up. We still need to make sure we keep up on routine computer maintenance but at least we can start to have an understanding of the things we can not control that contribute to our slow computer.

Have you ever found yourself in the situation where you need computer repair parts? Of course you have! After all this is the computer age and most of us have at least one computer or laptop in our homes. It is possible that somewhere along the way, your computer will begin acting up and you will think it is a virus, when in fact it might be a problem with software compatibility due to a recent upgrade. While there are many different software tools available via the Internet, there are times when using an onsite repair service is in your best interest. This is especially true if there is concern about losing valuable data or those family photographs that are irreplaceable.
Finding the Solutions Yourself
There are ways available for you to try fixing your computer problems yourself. However, make sure you don’t do more damage, because it can make your repair bill higher, when you end up calling for onsite computer repair. Experts certified in onsite computer repair services can install the computer repair parts you need and offer solutions to solve software problems and data protection concerns. Some experts will even recommend some informational books to help you that you will be able to find at Amazon books or possibly through an online e-book.
Hard Drive Backup Solutions
There are options for backing up your hard drive to protect your data. Onsite computer repair services can advise you on the best solutions for hard drive backup solutions, in the unfortunate event your hard drive is one of the computer repair parts that needs to be replaced. You can purchase mirror hard drives, but you have to make sure that you schedule regular backups and many times, your programs and data files might not be complete. Some repair services are able to recommend Internet-based providers, like Mozy for hard drive backup, for example.
Finding Your Own Parts
Some people are computer savvy enough to have the mechanical ability to replace some computer parts that are easy to access. Places like Tiger Direct sell new and refurbished computer products and parts and Dell offers replacement parts, as well. Just keep in mind this isn’t something that amateurs should attempt. Because you can lose valuable data and corrupt programs, as well as cause additional parts to be needed that might not have been needed to begin with. When you are certain that you have hardware problems and need computer repair parts, consider the experts that can fix your problem the most economically.
Adding More Memory
Most computer experts would recommend that you know the exact computer repair parts you need, when you want to add more memory, because you don’t want to damage your motherboard. Again, this something that you can undertake yourself, if you are knowledgeable in this area, and helpful tools are provided by Crucial Memory so you can find the correct memory for your motherboard. However, if you are unsure about this task, it is easy and affordable for onsite computer repair services to install additional memory with the correct computer repair parts. This might be worth the peace of mind and it is an affordable option.

When most people think of computer networks they think of large businesses. Many people have networked their home systems to enable a shared internet connection, shared files and even shared printing capabilities. The process of sharing resources and data between more than one computer is referred to as computer networking. When you link the computers together they are capable of not only sharing the internet connection, printer, FAX and other components but are also capable of sharing files, pictures, songs and other data stored on the hard disk.
The network can be divided into a local or small area network such as a LAN network where computers are shared within an office building or home space, MAN where two or more locations are connected throughout an area and WAN where the network can be created to connect to a home or office from anywhere in the country.
WAN is the most common use for connectivity, it allows the network to connect to millions of computers across the globe. The WAN network is the world’s largest network and through connection if a router and running the proper software you can be connected to any location from just about anywhere in the world.
Computer networks can be wired or wireless, although there are not many who use the wired feature these days. Depending on the set up you need, how you need to access the main computer and how many you need to link together will determine the type of network you need to create.
There are two main ways to connect the computers, through client-server systems and through peer-2-peer servers. The client-server network has a main computer or computers that work as the server for the network. The data, files, pictures, docs and other information is stored on these servers that are then accesses from various computers that are on the network. The other computers in the network are called the clients and they are linked to the server to get any or all of their information.
Peer-2-Peer networks allow each computer to choose what information will be shared. There is no main server where it is all stored, each hard drive is open to the network and each computer on the network will be given the appropriate access to the hard drives on each system. Most home users have the peer-2-peer network setup where they can pick and choose what information is needed or wanted from each system in the home on the network. Most businesses use the client-server network with different topologies or structures or designs within their layouts.
The common language or communications between computers when networking are known as protocols. The most popular and commonly used protocols are the TCP/IP where it works with several protocols and not just a single protocol. The TCP/IP protocol can be used and will work with either wired or wireless connections and can be used through the client-server or peer-2-peer networks.
Setting Up a Home Network
There are some great programs out there that will walk you through setting up a home network in no time. You do not have to be a network engineer and it takes little knowledge of how the network actually works. You basically only have to the systems you wish to connect or link together in the network, an internet connection and the ability to follow simple instructions. If you are setting up a wireless internet connection you will not have to worry about running cables from one computer to the next and the only thing that will be done is some simple changes in the networking section of each computer. You can create a secured connection that is protected with a password to ensure that you do not have an open connection to outsiders who wish to snoop through your shared files. You get the option on each system to choose what you want to share and what you do not. You can create a folder that is for the network and put it on a virtual drive, this way no one can enter the actual computer’s hard drive, just the file and what is stored on it. The process for computer networks is simple and easy to do and can make a multiple computer home run much smoother.

Is the iPad going to revolutionize modern thinking on technology and communications? Will the iPad bring mankind's consciousness closer together than ever before? How is the iPad going to change society and culture. Are we destined to end up like that blind guy from star trek with an Internet visor?
Well, now that it's likely that the apple tablet is to be called the iPad it will definitely not have any disturbing social impact … looking back in tech history on this great product and wonder … "What the hell were they thinking? " But on the off chance that it will be called the iSlate (a far better and more elegant name) we may find ourselves in a brand new world. And by brand I mean the brand of Apple.
Apple could take over the world with this facing off against it's biggest competition: Google. We all know that the future (and our money) will belong to one of these two companies. But enough of this talk … I'm not writing about corporate politics. Next topic.
Everyone is saying that the iPad will "save print media" if this is in fact true, then this device (iPad / iPad) will indeed change how the world views information technology almost as much as the Internet has affected IT.
Pretty soon we'll be forgetting what "real paper" looks like and be absorbed into virtual reality like we've been trying to do for years! Woah now, let me not get ahead of myself. We're not going to be eat up by computers and enslaved by evil machines … at least not yet. Although, did not one of those terminators have the apple logo on it?
Ok, lets get serious. The iSlate or iPad probably will not be game changing, but it will be really really cool and convenient for a bunch of reasons, but we will not know why we want it till we see it.
Stay tuned, next Wednesday will be Judgment day!
UPDATE: The iPad (bad name) is here! Just got informed! So come back for more!
