Some facts about Automobile Mirrors
I am a rider - I ride both two wheelers and wheelers. I haven’t got the 3 wheeler license. Maybe I will get one sometime.
I was wondering what type of mirror does an automobile use - flat, convex or concave. I searched and got the answer to my question - convex mirror instead of concave or flat mirrors as rear view mirrors because they can make a larger area be seen with just using a small mirror, while concave mirrors tend to enlarge the objects, which gives the viewer such a small range of sight. It will give you a broad look to uncover blind spots but drawback is that it will distort the view a little bit - Thats why they write on those mirrors -Objects in the mirror are closer than they appear’.

Just another fat burner?
One of the fat burners which caught my attention these days is apidexin. It contains DiCaffeine Malate, ThermoDiamine, ForsLean, Fucoxanthin, GuggulEZ 100, Razberi-K, Lipolide-SC, Bioperine etc. Out of these only DiCaffeine Malate seems a bit problematic - because it could cause jitters, insomnia, headaches, increased heart rate and blood pressure. So far I have seem some very good reviews about Apidexin. Very few people seems to have reported some problems (mostly you will find much more complaints about a product).

Exit
Exit signs are mounted in almost every building we go into, like high schools, grocery stores, movie theaters and shopping malls. Many exit signs contain tritium, the radioactive form of hydrogen. Mixing tritium with a chemical that emits light in the presence of radiation, known as “phosphor in a tube” (a sealed source), creates a continuous, self-powered light source. This useful property of tritium can be applied to situations where a dim light is needed but where using batteries or electricity is not possible.
Using tritium in exit signs ensures that the sign will remain illuminated in the event of an electrical outage or a fire. If the tubes in the exit signs are severely damaged, the tritium, which exists in the sign as a high temperature gas, might escape into the local area but most likely will quickly disperse in the air. Because a damaged exit sign will have relatively high levels of tritium in it, you should not handle it.
While damage to tritium exit signs is rare, it is most likely to occur when a sign is dropped during installation or smashed in the demolition of a building. If not damaged during demolition, tritium exit signs can be broken when they are illegally dumped in community landfills.
Tritium is naturally produced by the interaction of cosmic rays with the atmosphere. Tritium can also be produced by man-made processes, as is the case of tritium exit signs. Tritium decays by emitting a low-energy beta particle that cannot penetrate the outer layer of human skin. Therefore, the main hazard associated with tritium is internal exposure by inhalation. Internal contamination occurs when people swallow or breathe in radioactive materials, or when radioactive materials enter the body through an open wound or are absorbed through the skin. Some types of radioactive materials stay in the body and are deposited in different body organs. Other types are eliminated in blood, sweat, urine, and feces.
As with all ionizing radiation, exposure to tritium increases the risk of developing cancer. However, tritium exposure is likely to have a limited biological impact because it emits very weak radiation and leaves the body relatively quickly. In addition, because of tritium’s short half-life, tritium must be ingested in large amounts to pose a significant health risk.

Cell phone signal boosters
Cell phone signal boosters, including wireless repeaters and inline cell phone boosters or cell phone amplifiers, extend cellular service in poor coverage areas by amplifying both transmit and receive signals. These cell signal booster amplifiers reduce problems with dropped calls and signal fades while improving service range, voice quality and access. These multi-mode amplifiers are designed to offer a cost-effective solution for use in buildings and mobile installations.
Cell phone repeaters are an emerging technology of bi-directional cellular amplifiers. If you are suffering from weak cellular signal, then a cellular repeater system can help you by improving the cellular reception that you experience. It does this in two ways:
1. A cellular repeater system will include an antenna which sits outside your building, where the cellular signal is stronger, and feeds this strong signal into your building through a low loss cable.
2. The cellular repeater system actively boosts this signal through the bi-directional amplifier. It is a bi-directional amplifier because both incoming and outgoing signals are boosted.
After a rocky start, cellular repeater technology has much improved and now there are a variety of repeaters which are licensed by the FCC, the body which monitors the communications industry. Be sure to look for this endorsement when buying a repeater, but rest assured that all cellular repeaters from the established manufacturers such as Wilson Electronics, Clear Voice and Wi-Ex zBoost have this accolade included. Cellular Repeaters come in a number of different flavors e.g.. In-Vehicle versions, Large building versions and standard home/small office versions.
Cellular Repeaters (Wireless)
Wireless boosters improve the cell signal for multiple users simultaneously without a physical connection to the phone or device. Models are available for vehicle, home, office, RV and marine applications. Amplifiers are available both standalone and as part of complete repeater kits.
Inline Boosters (Direct Connect Amplifiers)
Inline boosters connect directly to a cell phone or cellular data card providing improved signal to a single user at a time. When combined with the appropriate cellular antenna they provide optimum cellular signal enhancement.

What is Mesothelioma?
Mesothelioma is a cancer that develops within the mesothelium of the body. The mesothelium is the protective covering in the body. It covers various organs, including the lungs. The mesothelium is made up of two thin layers. When cancer develops in the mesothelium it is between these layers. The narrow space makes it very difficult to diagnose mesothelioma in the early stages.
Mesothelioma is a difficult cancer to treat. Once a diagnosis of mesothelioma is made, the majority of patients will not live longer than eighteen months. There are a variety of reasons for this, including the advanced nature of the disease once it is diagnosed and the lack of an effective surgical method of removing the tumors.
While most cases of mesothelioma occur around the lungs, it can also occur in the abdominal mesothelium, called the peritoneum, or the pericardium. While mesothelioma is most common in the lungs, it is important to differentiate between mesothelioma and lung cancer. They are two very different types of cancer and require different types of treatment.
How Does Asbestos Exposure Occur?
Asbestos is a naturally occurring mineral that has been used for centuries in various products. Asbestos has many attributes that make it valuable, including fire resistance. Asbestos was used in many products that were made for protection from heat and flame. This included actual clothing, such as gloves, to stuffing asbestos insulation into electrical conduit, to using asbestos to make fire proof cloth for use in power plants or petroleum refineries.
Asbestos also has excellent insulation and noise deadening qualities. This meant that asbestos was used in many construction products, including floor and ceiling tiles and wall board. Any home built before 1978 probably contains asbestos somewhere.
Asbestos exposure occurs when the asbestos that is in the products becomes damaged. Once damaged, the asbestos fibers are released into the air. The fibers are microscopic, smaller even than a grain of pollen, and invisible to the naked eye. The asbestos fibers, if inhaled or ingested, can become lodged into the body where it can create severe medical problems.
What is Asbestosis?
Asbestosis is a chronic inflammation of the lungs. The inflammation is a direct result of exposure to asbestos. Asbestosis is a progressive disease with no cure. The inflammation causes shortness of breath, which will get progressively worse as the disease progresses. Physicians can treat some of the symptoms of asbestosis with auxiliary oxygen, but it will not cure the disease. Death due to asbestosis occurs by respiratory failure.
Your Long Term Health
Asbestos related diseases, including asbestos cancer, do not show up until decades after exposure. Because of the long latency period between exposure and illness it can be hard to determine if you will suffer from asbestosis or mesothelioma. While asbestos exposure is the only way to develop these health problems, you may reduce or delay their development by taking care of your lungs today.
To protect your breathing:
* If you do smoke, stop. In addition to mesothelioma and asbestosis, there is research that indicates that those who suffer from asbestos exposure and smoke are at a greatly increased risk of developing lung cancer.
* Stay physically fit. Everyone’s definition of physical fitness is different, but up to thirty minutes of activity most days of the week will provide the most benefit. Physical fitness is important for healthy lungs.
* Eat well. While there is no direct correlation proven between diet and mesothelioma or asbestosis, filling your meals with leafy and fibrous vegetables as well as whole grains has been proven to reduce the risk of other types of cancer.
What to do if you Think You May be at Risk?
If you think that you may have been exposed to asbestos at any time, it is important to share your concern with a physician. While asbestosis has no cure, early intervention can slow the progression of the disease. Mesothelioma is a very aggressive form of cancer, and one of the reasons that it has such a low survival rate is because it is not typically diagnosed until the disease is fairly advanced.
If you worked in an industry that has a high rate of asbestos exposure, you should consider yourself at risk of developing an asbestos related disease. Some occupations that had high rates of exposure include ship builders, petroleum plant workers, power plant workers and construction workers.
If you are concerned about asbestos in your home you should research the best remediation methods or hire an experienced contractor to do it for you. Although the remediation is not difficult, you must be careful and follow specific guidelines to reduce the risk of suffering from accidental exposure.
Asbestosis and mesothelioma are both serious conditions that can be a death sentence. While you may not be able to undue previous exposure to asbestos, you can commit to reducing your risk of exposure in the future, and take care of your body so that it will have the best chance of battling any disease that you may develop.
