Metal Fabricators – A Boon to Metallurgy

Every now and then, we keep hearing of the term ‘steel metal fabrication’. But have you ever wondered what metal fabricators are used for? This article will give you a glimpse into the world of fabrication and how it is fast becoming the next big thing in metallurgy.

As the term suggests, fabrication means constructing metal structures with the aid of cutting, bending and assembling. The processes of shearing, sawing and chiseling are utilized for the cutting part. The bending of the metal is done by hammering or by using press brakes which can be done both manually and by using power. Last but not the least, the assembling process is conducted by welding, and then attaching them with adhesive, riveting or threaded fasteners.

The metals which are essentially required for steel fabrication are structural steel and sheet metal. Besides these, one also requires welding wires, flux and fasteners to attach the metal cut pieces. For the process of metal fabrication both human labor and automation is required. The final products are sold in shops which also specialize in metal stamping forging and casting.

Steel metal fabrication is used in various segments and we will explore various areas where it is extensively used. It is generally used in fabrication and machine shops which basically deal with metal assembly and preparation. In these shops, metals are dismantled and cut and they also deal with machines and tools. Black smiths also use the process of metal fabrication and so do welders to create weldments. Boiler makers and mill wrights who set up saw and grain mills extensively also extensively make use of metal fabricators. The steel erectors or iron workers use prefabricated segments in order to initiate the structural work and then they are transported to the work site by means of truck and rail where they are installed by the erectors.

The technique of metal fabrication involves changing metals from one form to another. There are various classes of the fabrication process including structural, architectural, ornamental, recreational and artistic. If you are interested in fabricating a metal you have to determine whether it contains iron or is ferrous or whether it is non-ferrous. You have to choose the appropriate welding instrument which will correspond to the metal which you are going to fabricate. Before beginning the work you have to prepare a well-laid plan which includes the details relating to rolling, bending and bolting metal pieces together to create a highly specialized structural piece of work.

The Avian Plight

In 1997, the world’s attention was caught by an alarming passage of Avian influenza from birds to humans in Hongkong. All chickens and ducks were killed upon the order of the Hongkong government to contain the spread of the deadly H5N1 virus.

Avian influenza or more commonly called as bird flu is an infection caused by avian (bird) influenza (flu) viruses. All birds naturally have these influenza viruses in their bodies. Wild birds have these viruses in their intestines but their bodies do not get infected or damaged by them. When passed on domesticated birds, avian influenza can cause sickness and death. Chickens, ducks, and turkeys are mostly hit by the   transmission  of avian flu among birds. Infected domesticated birds can pass on the virus to humans when they are eaten or consumed. *Migratory birds* infected with avian flu also become agents of viruses’ transfer from one place to another.

H5N1 carrier birds pass on the virus to other birds through their saliva, nasal excretions, and feces. Birds get infected when they come in contact with these contaminated excretions even by just staying on a surface or ground where virus carriers have stayed. Cages, dirts, water, feeds, infected waterfowl or other poultries that have been exposed to the virus are the common sources of infection among domesticated birds.

Two forms of bird flu exist among domesticated poultries infected with avian influenza viruses. The low pathogenic form is almost invisible and undetected for it causes only very mild symptoms that can be mistaken as non-avian flu effects. Manifestations of low pathogenic avian flu infection include low egg production or ruffled feathers. The second form of avian flu is the high pathogenic avian flu disease. This form leads to multiple organ failures and damages among infected birds. About 90 to 100 percent of birds infected with this form die within two days upon contamination. The spread of this form of avian flu is more rapid among birds in flocks.

Albeit basically a matter among birds, humans are also susceptible to bird flu or avian flu infection. The first known cases of humans getting infected with bird flu happened in Hongkong in 1997. 18 people were recorded to have acquired respiratory illnesses after having contacted infected surfaces from poultry farms, the infection claimed six lives.

The virus’ passage to humans that happened in Hongkong caused a global alarm. Health institutions worldwide raised concerns that the avian flu might be as damaging as the pandemic of flu that claimed about 20 million lives back in 1918. Reasonable enough, the fear and alarm are worth noting. What is essentially fearful is the idea that humans can be infected and actually die from a virus that is basically existing among birds only. The premise the Hongkong incident set is that the virus is mutating into something deadly for humans.

As of 2005, worldwide coordinated statistics recorded a number of 130 people having been infected of avian flu of which 67 have already died. In recent years, cases of human infection have been high in Asian countries. The World Health Organization believes that Asia is at higher risks since people live in close distance with domesticated birds like chicken and ducks. Animal domestication and poultry raising are common among many Asian countries who are agricultural by nature. What worries many is the common fact that humans have little or even a lack of immunity to the virus known to be infecting only (until the 1997 Hongkong incident) the birds.

An even higher cause of alarm has been found in recent studies on the H5N1 virus. Recent researches have shown that H5N1 strains have become more deadly among chickens and mice. This mutation is also found to be making cats or feline susceptible to the infection. H5N1 is also found to be resistant to some of the drugs used to treat flu (such as amantadine). New strains of the virus are also said to be possibly emerging especially in Asian countries.

What is now being focused on by scientists and health experts around the world is the prevention of human-to-human  transmission  which is believed to be the possible case that happened in Thailand in 2004. If it becomes widespread, human-to-human  transmission  is believed to be harder to contain that bird-to-human  transmission . Experts say that the virus’ continual change will make it hard for the human body to naturally develop immunity against the infection. The H5N1 virus is found to be changing over time through the changes happening in their structure called antigenic drift and antigenic shift. This continual change of the virus disables the immune system to respond accordingly whenever the flu virus enters the body. The only possible solution seen by experts is for infection-prone people to have a yearly immunization with up-to-date anti avian virus strains. But the big problem is, until now there is no medical treatment available to combat the H5N1 virus, making the yearly immunization update a far-fetched option.

Dirofilariasis – The Deadly Heartworm in Dogs

When a dog is suffering from heartworm, it means that they are infected with a roundworm commonly known as heart worm. The organism is actually Dirofilaria immitis, a parasite. This worm is transmitted by mosquitoes and will infect your dog’s blood, heart and lungs. Left untreated, the disease is fatal.

Causes

Heartworms are spread through mosquitos that carry the infective heartworm larvae. The larvae enter the dog’s body through the mosquito bite wound and travel through the dog’s body to the heart. This process will take approximately six months.

Once the heartworms are living inside your dog, the adults will release immature heartworms (microfilariae) into the bloodstream of the dog. When a mosquito bites an infected dog, it will become a carrier of these microfilariae and infect the next dog it bites.

If a dog lives in a high risk area for heartworm, without preventative treatment it will almost certainly contract heartworm disease. Although heartworm is mainly endemic in tropical and subtropical areas, it is not limited to these areas. Heartworm has been identified in all 50 US states and is found worldwide.

Symptoms of Heartworm

Heartworm disease can be diagnosed by your veterinarian through a blood test. There are three classes of heartworm, and the symptoms vary from no visible symptoms to extreme ill health. It is difficult for a dog owner to identify heartworm in their pet.

The symptoms of heartworm include but are not limited to an occasional or more regular coughing, reduced canine activity or an intolerance to exercise, anaemia, fainting, chronic heart failure, labored breathing and high blood pressure.

The severity of heartworm disease will depend on the severity of the infestation, the duration of the disease and the response of the dog. All dogs are different in the way their bodies cope with the heartworm infestation.

Diagnosis

If your vet suspects your dog may have heartworm they can conduct a blood test, carry out an electrocardiograph (can reveal heart rhythm disturbances), a urine analysis or x-rays. They are looking for damage to or enlargement of the heart and associated arteries.

Treatment

Initially your dog will be hospitalized, and receive a dose of adulticide which will kill the adult heartworms. Depending on the severity of the infestation your dog may need to be hospitalized for a longer period. In some cases surgery may also be required to remove adult worms from the heart and jugular vein.

After the adult worms have been killed, treatment must be ongoing with a monthly dose of prophylaxis to kill eggs and larvae which have not been killed by adulticide.

You should be aware that the treatment for heartworm can be deadly. Even mild to moderate cases of heartworm will have a considerable impact on your dog. It is not an easy treatment for your dog, and should not be considered light heartedly.

Prevention

Heartworm disease is completely preventable through a regular dose of prophylaxis which is a preventative heartworm medication. Your veterinarian will be able to assist you with the appropriate medication and dosage to suit your dog.

If your dog does contract heartworm and has been successfully treated, you should take care to administer the monthly dose of prophylaxis as advised by your vet – reinfestation can easily occur especially in high risk areas.

What is CNC?

CNC is the acronym of Computer Numeric Control and it is often associated with plasma cutting as in CNC plasma cutting. A plasma cutting unit that is controlled by CNC is controlled by a computer. There are two basic classes of controls, industrial PC-based control systems and hobbyist/artisan PC-based control systems. The industrial CNC systems, such as the ones produced by Hypertherm or Burny, are robust enough to stand up the harsh production environments. They have a touch screen that can be housed inside of a heat shield for additional protection. The industrial CNCs are very costly, but they come highly recommended for any application because they are not vulnerable to typical PC problems meaning they have very little down time. Due to the high cost you will not often find industrial scale CNCs in a hobbyist’s garage. The artisan and the hobbyist plasma cutter use standard PC-based controls with I/O cards for controlling the plasma systems and the drives. Since these are regular PCs they are prone to an array of computer problems, but none that cannot be fixed.

If you want to use a CNC for your plasma cutting there are some things you will need. You will need a table for the cutting to take place on. On each side of the table you must have a rail that the drives can use to move the plasma systems; we will call this the x-axis. A bridge or gantry must span the table and each end must rest on the rails. The plasma system must be attached to a rail on the bridge which will allow it to move back and forth; the y-axis. Industrial strength set ups us fabricated steel for the construction of the table, rails and bridge. On the other hand, extruded aluminum is used for the hobbyist and artisan CNC plasma cutter set ups. The difference is that the steel is more robust and will withstand constant use whereas the aluminum can only withstand occasional use. If building one of these machines sounds a little scary to you, there are lots of kits that you can buy or you have the option of buying ready built CNC plasma cutters.

If you cruise the web you will be able to find many videos showing CNC plasma cutters in action. It is not the easiest topic in the world to explain and I suggest you check out some videos if you have not seen a CNC plasma cutter before.

How to Know If You Have Male Yeast Infection

Many males will be embarrassed by the fact that they have a yeast infection and will often not seek any medical help. A yeast infection is not something to be ignored and this article should help you to at least determine whether or not you have a yeast infection.

While, it is commonly said that a male yeast infection is a minor problem that can be eliminated by maintaining proper personal hygiene, the fact is that neglected male candidiasis can lead to severe health complications up to damaging the male reproduction organs. This is why it’s obligatory to learn about the symptoms of male yeast infection and ways to initially and properly diagnose the condition.

The following 5 categories will help you to know if you have a male yeast infection:

1. Painful

Things such a jock itch, burning sensations during sexual intercourse or urination. If the pain is server it is a good idea to see a doctor or seek out treatment immediately.

2. Visual

These include dry skin which may be flaky, redness of the penis head and in extreme cases a white discharge.

3. Indigestion

These will include problems such a constipation, diarrhea, intensive gas an in extreme cases even bad breath.

4. Fatigue

A simple lack of energy and mood swings.

5. Sexual dysfunction.

The inability to get or maintain an erection without pain occurring.

6. Dietary preferences changes

Most common of which are cravings for sweets and refined carbohydrates, etc. This is a bad thing because if you have a male yeast infection these types of foods should be minimized

Note that the last four male yeast infection category symptoms are associated with almost any other yeast infection subtype as well. This fact supports the widely accepted alternative medicine philosophy that claims that candida balanitis is first and foremost an internal problem that needs to be addressed holistically rather than a local or external condition.

If you are able to identify any of these symptoms then it is very likely that you have a male yeast infection. Many men are not very forthcoming about seeking help but this is a dangerous approach because a yeast infection should be looked at and treated as soon as possible.

Mononucleosis Explained

Mononucleosis is a viral illness that is common among young adults but can affect people of almost any age. Severe sore throat, swollen lymph nodes, fever and extreme fatigue are the recognizable hallmarks of this condition. Why the disease is more common in teens remains unclear. It may have something to do with the lifestyle, poor diet, not enough rest and stress, all of which lowers the resistance of the immune system. The underlying culprit is the Epstein-Barr virus (EBV). This virus, a member of the herpes virus family, is so common that 95% of all adults test positive for exposure to it. The EBV has been implicated as playing a role in some uncommon malignancies later in life or another condition chronic fatigue syndrome. However, keep in mind that the virus is very common. Even though exposed some time in their life by adulthood, most people do not manifest any clinical symptoms of mononucleosis. Viral transmission occurs through intimate contact with saliva or blood of the infected person. Hence, the antiquated name of the “kissing disease”. The virus is not airborne. The risk to others in the family or friends is very low unless there is intimate contact.

Severe sore throat, extreme fatigue, swollen glands and lymph nodes characterize the typical symptoms. The inflammatory process usually affects the liver and spleen resulting in some enlargement. In a small number of severe cases, abdominal pain or difficulty swallowing may be an issue. Twenty percent of people with mono develop a fine red rash resembling measles. Some medications in particular amoxicillin based antibiotics can also trigger the rash. The incubation period from time of exposure to onset ranges from 14 to 45 days. The average illness lasts 4 weeks. The first two weeks are most difficult because of the intensity of the symptoms including a severe sore throat that makes it awkward to maintain an adequate diet. The fatigue makes people want to sleep a lot. People usually miss two weeks of school or work during this time. The second two weeks are usually quite a bit better but energy levels are still waning. Getting up in the morning feeling good and somewhat energetic, but running out of gas after a few hours is characteristic. Some modification of activities with a limited schedule during the second two weeks is to be expected. A specific blood test can confirm the diagnosis in the doctor’s office. An exam to rule out other similar conditions is prudent.

Since it is a viral illness it will run its own course, there is no specific treatment. The majority of cases improve with rest and a balanced diet. In the rare severe case, other medications such as a steroid or an anti-viral drug may be used. There are a few instances when a second bacterial infection such as strep throat may occur at the same time. Appropriate tests can easily determine whether an antibiotic is necessary to treat a secondary infection. Symptomatic treatment is helpful just like treating the flu. Ibuprofen or acetaminophen for fever or muscle aches, plenty of clear liquids and trying to maintain a healthy balanced diet are nonetheless important. Avoiding alcohol for six weeks is suggested while the liver inflammation subsides spontaneously. The biggest frustration for people is simply the lack of energy and fatigue. It can usually take 4 to 6 weeks or more before normal stamina returns.

All that counts is that the course you partake in is accredited and approved by the state in which you wish to practice in.

When you find a free CNA class to use online, don’t just rely on the limited materials given but use all your resources and study hard and make the time spent worth it.

Interactive Technology in Healthcare Education

Healthcare professionals are under pressure to remember, utilize and absorb vast amounts of new or changing information in increasing volume. This surge has led to new and improved computer-based tools for many healthcare activities and to an explosion in the marketplace of tools used in instruction and education of healthcare workers. This article explains the use of interactive technology in healthcare and how this benefits instruction and education of healthcare professionals.

Digital systems that capture images from documents, 35-mm slides, physical samples or specimens, or virtually anything that the camera lens can see, is found in interactive technology. In healthcare, transmitting these images to computers with simple devices or software that will allow the display and integration of educational material into the training environment is easily accommodated.

The method for delivering these images or documents, usually via PowerPoint presentations, photography, videotape or audio presentations can turn a standard Windows PC into a dynamic, interactive, teaching tool. Depending on the type of training environment needed, interactive presentations can be found in the use of liquid crystal displays, large plasma displays, rear projection systems or even whiteboards. Educators can now tailor their courses to their audience’s expectations and needs using any number of these presentation forms.

Effectiveness of interactive learning systems is largely dependent upon the type or form of delivery used in combination with software that is easily used by both novice and expert users. Smaller systems will use a pen or stylus vs. a computer and a mouse where larger systems may use elaborate videoconferencing systems where many participants can be in the virtual classroom at the same time. Many healthcare organizations already utilize small and large types of communication systems routinely in the delivery of quality, high-tech healthcare to patients and their community. Adapting this equipment or having it serve dual purposes is an easy and cost-effective transition.

The era of the blackboards and chalk dust is now a memory for most of us. Interactive technology tools permit the educator to draw on, write on, and annotate data right on the screen as part of their dynamic presentation. In addition, the educator can now annotate their presentation and then save, print and even distribute by email, the contents of the class session to all participants.

The mobility that interactive technology gives the educator in the virtual classroom lends itself to unlimited types of uses and methods for delivery of high quality, interactive, sessions. Participants, too, benefit from easy access to the sessions, improved and more accurate note-taking that can be used later for study and reference. This all leads to greater retention of the learning objectives and enhanced or improved application in the field once the participant returns to the office or department.

Healthcare professionals should look for educators and learning systems that combine ergonomics with interactive technologies that integrate use the user of free text, annotation, images and video clips with the traditional printed materials. Transitions between screens or programs, linking to the Internet and class sessions, downloading or printing of the course materials and saving of files or information for future classes or reference use should be easy and simple to use. The presentation and delivery of the educational material should be efficient and easy to use and tailored to use by both healthcare professionals that have varying levels of technological skills.

Regardless of whether healthcare workers are new to the workplace or seasoned professionals, the learning systems used should assist them with learning new skills, procedures, diagnostic techniques and terminology. Communication between healthcare workers in both local and distant communities is on the rise and the use of interactive technology enables the participants to collaborate and share critical data and information.

Interactive technology can also benefit the bottom line and reduce costs formerly associated with travel or staffing and resources to send workers to local, regional or national meetings. Interactive presentations and systems can also attract and hold the participants interest and attention, enhancing their learning and retention gained from the course(s).

It is no wonder, then, that interactive technology has gained such a strong and prominent position in the education of healthcare workers. Healthcare workers looking for either online, distance or local training should evaluate the presentation and delivery systems used in order to maximize their learning experience.

SUVs Meet High End Luxury (And Are Kind to Your Wallet)

Sport Utility Vehicles (or SUVs) have become increasingly popular over the last several years, with more and more manufacturers adding their versions to the market. With their ability to function well as both on and off-road vehicles, large storage space, ability to fit several passengers as well as towing abilities, SUVs serve as a very practical solution for much of the automobile buying market. Quality SUVs also handle well, feeling much more like driving a car than a massive truck with many of the same benefits.

While SUVs have always held a certain authority and status due to their size, they are often placed in a separate, “practical” category from the truly high end luxury cars. Fortunately, a few upper-echelon manufacturers have released their own versions of the SUV, blurring the lines between practicality, performance, style, and luxury interior. These include:

– BMW X5

– Lexus GX

– Mercedes G and M classes

– Audi Q7

– Porsche Cayenne.

The BMW X5 Series is a mid-size SUV in the market since 1999. Features include all wheel drive, and V8 engines with gasoline inline. E53 and E70 are the two generations of the model. The E53 model has many features of Landrover. The E70 model is more of a Sports Activity Vehicle. Other luxuries such as high pressure headlight washers, heated front seats, heated steering wheel, leather seats, automatic climate control, automatic light control, and sun roof add to the comfort and luxury of the vehicle.

The Lexus GX can seat up to 8 passengers. It has many great features including a welded steel body, center locking permanent 4 wheel drive, built in mudguards, illuminated running boards, electronic 5-speed automatic   transmission , and the innovative, unparalleled luxury interior and amenities customary in all Lexus models. Models from 2004 and up feature additional safety modifications like tire pressure monitoring, roll-sensing, side curtain airbags, and a Dynamic Suspension System. Like most Lexus models, the GX has won several awards: 4 wheeler of the year, highest ranked luxury SUV for quality, and best resale value from sources like 4×4 Magazine, J.D Power and Associates, and Kelley Blue Book.

The Mercedes G-Class is a four-wheel drive sport utility vehicle launched in 1979, originally created for military use with a jeep-like look. The three generations of the vehicle are W460, W461, and W463, and it is hailed for its long lifespan and durability as well as off-road performance. The interior of the car is made of wood or leather. The automatic  transmission , power steering, airbag, central locking, air conditioning, engine pre-heater, electric windows, and heated seats really add to the sense of luxury.

The M-Class by Mercedes is a mid-size SUV introduced in the market in 1997, featuring stability control which helps in bringing the vehicle to a halt in case of emergency. Excellent features such as seven speed automatic  transmission , Active Curve illuminating Bi-Xenon headlights, 4-valve engines, and air suspension which can be adjusted are major attractions of the vehicle. The cars also use BlueTec Diesel engine for controlling diesel gas emissions. New front headlights, exterior mirrors, redesigned front grille, an improved interior, and front and rear bumpers add to the beauty of the car. The M class won the “Truck of the Year” in 1998 awarded by Motor Trend magazine. Also it was named “Best New Sports Utility Vehicle” in the year 2006 during Canadian Car of the Year Awards.

The Porsche Cayenne is a five-seat mid size luxury sports utility vehicle launched in 2002 with two generations. The engines in the models introduced from 2008 have direct injection technology. The main features of the car are height adjustable off-road suspension, slanted rear window, remodeled dashboard, taillights near the tailgate, lighter weight due to the usage of aluminum, and fuel efficiency. Owners love the climate control, cruise control, leather upholstery, heated front seats, power sunroof, radio control, and leather-wrapped steering wheel. Features such as a rear view camera, memory system, navigation system, sound system, climate control, and CD changer make the car an excellent marriage of luxury and SUV performance.

Price of course is always an issue, but these world class SUVs can be found online at surprisingly good deals. At the time of this writing, HighEndAutoAuctions.com has multiple BMW X5s under $15,000, several Cayennes under $20,000, and several steals on each of the other models. No matter which source you choose to purchase from, these models are sure to satisfy both your practical needs and luxury desires.
