Working of Modern Flying Cars

admin — Wed, 01 Feb 2012 08:11:13 +0000

Though we commonly use ‘flying cars’ and ‘roadable aircraft’ as synonyms, they have a slight difference (which is easy to spot). Flying cars are cars adapted to fly while roadable aircraft are aircraft adapted to be used on the road. The inventors of the early flying cars worked more on adapting a car to fly in the air while the recent inventions of flying cars have been in adapting an aircraft for asphalt roads.

Whatever may be the case, a modern personal air vehicle will need to have the following modified features (all related to the basics discussed before):

Engines
These engines should have enough horsepower to lift the vehicle into the air and at the same time, be capable of providing controlled power for the vehicle to move on the road. The flying car will need to have an extra engine, if there is an engine failure during a flight.

Aircraft Propellers
Because the vehicle will be flying, it will obviously need the propellers (aircraft blades and wings) found on every aircraft. But as these wings will not be needed on the roads (obviously), they will have to be either easily detachable or foldable.

Landing Gear
To land the flying car on the ground, it will have to be fitted with the essentials found in the cockpit of a normal aircraft. It would have to be able to take the impact from the road and be able to balance itself to be used on the road.

Material
Needless to say, a flying car will have to be lightweight, yet have adequate ground mobility. While on the roads, a vehicle is more likely to be damaged but a slight damage on an aircraft can prove to be dangerous. So the material used in a flying car should be both light and strong.

Design
A road vehicle needs greater flexibility than an aircraft. An aircraft needs to be aerodynamically designed for better flight. The conclusion? A flying car should be small enough to fit on the road and big enough to fly. The requirements increase if the said personal air vehicle has to be parked in a house garage!

Fuel
If the oil crisis of the 90′s hadn’t occurred, Ford Motors would have marketed the world’s first flying car (Fulton’s Aerocar), at that time. The point here is, with the increase in fuel prices and decreased availability of fuels, a flying car will have to be run on eco-friendly, safe and inexpensive fuel, for better success in the market.

Safety Features
The reason aircraft manufactures haven’t invested much in trying to offer low-cost private aircraft has probably got to do something with safety issues related to flight. Air accidents are more dangerous and fatal than road accidents. So if the inventors of a flying car are aiming the market of the masses, they will have to make it safe. For that, they will have to include features like safety cages, air bags, parachutes and/or crush zones, etc., (yes, they will still have to watch their flying car’s weight!) in a personal air vehicle.

How to Make Hot Ice from Scratch

admin — Tue, 03 Jan 2012 02:19:40 +0000

The two raw materials: baking soda and vinegar, used to make hot ice need to be free of impurities. Ensuring this is very difficult, which is why it is better to purchase ready-made sodium acetate. You can purchase it from online stores like eBay, Trade Me, etc. Sodium acetate is also available in warming pads, hand warmers, etc. Just cut open these pads or hand warmers with a knife and empty out the contents. However, sodium acetate obtained from these warming applications will appear like a gel. Nevertheless, it satisfies the purpose. Moreover, purchasing ready-made sodium acetate simplifies and speeds up the entire hot ice making process.

Requirements
•Sodium acetate powder (One cup)
•Water
•Steel saucepan
Preparation Procedure

Step 1
In a steel saucepan, add two cups of water and begin heating it. Now, gradually add a cup of sodium acetate into the water and stir, so that it dissolves. Do not add it all at once. Instead, add it gradually, ensuring all the crystals are getting dissolved.

Step 2
The solution should not be brought to a boil, instead must be heated on low heat. Do not overheat the solution, or else the solution will develop a yellowish or brownish tinge on solidifying. This will not look so appealing in a science fair, as it will not resemble ice.

Step 3
Keep stirring the solution, as you add sodium acetate crystals. Now, the key here is getting a supersaturated solution. This is because, if the solution is not supersaturated, when the solution is placed in the refrigerator, it will crystallize, thereby defeating the whole aim of the experiment.

Step 4
Since we are looking for a supersaturated solution, we need to make sure no more sodium acetate crystals dissolve into the water. You will know the solution is supersaturated, when some crystals remain at the bottom of the beaker or saucepan, even after stirring for quite a while. This indicates your supersaturated solution of sodium acetate is ready.

Step 5
You can also do it the other way round, wherein, you can first add sodium acetate into the beaker and then add water gradually. However, be careful not to add too much water.

Step 6
Now, that your sodium acetate trihydrate solution is ready, pour it into a glass or any dish of your choice. However, make sure the tiny, undissolved particles present in the supersaturated solution do not get transferred into the glass dish. The presence of undissolved crystals can cause the solution to crystallize. Allow the solution to cool in the refrigerator for an hour or so.

Step 7
After an hour take the solution from the fridge. You are now ready to make your own hot ice sculpture. Pour the solution over a crystal of sodium acetate and watch how the whole solution crystallizes to form a beautiful sculpture. After making a sculpture once or twice, you will gain better control over your hands and will be able to construct gorgeous hot ice sculptures.

Economy Vs. Environment: The Conflict

admin — Fri, 25 Nov 2011 02:12:45 +0000

Argument 1: Economic progress is said to improve our standard of living. On the other hand, this very progress can lead to degradation of the environment. The differences between these conflicting views are discussed below.

The economy vs. environment debate started few decades ago and it has become quite a popular one in today’s world where economic growth is associated with environmental degradation. Points mentioned in the following and subsequent paragraphs should help us find some useful information on this topic.

There is a common belief in our society that preserving the environment is somehow linked with compromising on economic terms. This very belief has fueled the economy vs. environment debate. However, the truth is exactly opposite to this perception of ours. In reality, there is enough that the planet earth can provide us to satisfy our needs. Our economy can prosper and sustain in the long run without putting undue stress on the natural resources. It is the greed to possess and enjoy as many luxuries as possible that has led to the state in which we find ourselves, today. The use of green technologies and renewable sources of energy should solve the energy crisis to a great extent without putting any burden on the existing natural resources. It means the economic growth of the country/region in question doesn’t get hampered owing to environmental concerns. There is another misconception that conservation efforts require you to spend a lot of money to be successful. In reality, it is the awareness and a bit of effort on our part that can save many trees and animals on this planet. Even a simple act of planting and nurturing a sapling holds great importance in the process of environmental conservation. Such kind of efforts need to be concentrated in order to bring about a bigger and long-lasting change. The following paragraphs throw light on different aspects of the economy vs. environment debate through explanations about various subjects. Let us start with the topic of environmental ethics. Before getting into the details of environmental ethics, one must be aware about globalization and its impact on the environment to get a better idea of the subject of economy vs. environment.

Argument 2: Industrialists believe that economic progress gets hampered by putting restrictions on the way their operations are conducted. Environmentalists, on the other hand, demand for impractical rules and regulations to be put on working of industries. The details on these arguments can be found below.

It is actually possible to keep the economy in good shape without harming the environment. More than relying on temporary solutions like issuing monetary packages to solve environmental problems, it is the conscientious approach towards sustainable development that can lead to a better and also an economically prosperous world. Merely imposing rules and setting guidelines won’t go a long way in the quest to conserve the environment. It requires a voluntary change in the mindset of people towards judicious use of natural resources. People should actually start thinking about the environment and surroundings as their own property. Only then, can a person truly care about nature. Following such ethics can definitely bring about a positive change.

Few of our environmentalists take an extreme view on the subject of conservation and oppose any and every developmental activity. Such kind of attitude not only blocks the economic progress, but also prevents a reasoned dialog on environmental issues from taking place. No matter how hard we try, there is little possibility that we can completely repair the damage caused to our environment. It is therefore, necessary to become a little more pragmatic. You cannot change the established economic policies and systems overnight. It is however, possible to change our outlook towards the way we go about economic development. The developmental policies should be all-encompassing. Merely human-centric development won’t help much in the long run and which is why we have to question the prevalent economic policies that revolve only around human welfare. The next paragraph deals with this crucial aspect of the economy vs. environment debate.

Disadvantages of Forensic Science

admin — Fri, 04 Nov 2011 06:31:38 +0000

Despite numerous advantages of forensic science, there are some ethical, legal, and knowledge constraints involved in forensic analysis.

☛ DNA analysis of a person is believed to be against human ethics, as it reveals private information about an individual.
☛ Equipment used in forensic science is expensive.
☛ Scientific analysis in forensic science consumes lot of time because of which the verdict is delayed.
☛ Forensic science requires precise and accurate analysis. Even if a minor error occurs in the analysis, it may result in the wrong figure.
☛ The evidence cannot be accessible at all times.
☛ Evidence is prone to manipulation, which may end up in an unrighteous verdict.
☛ Interpretation of the analysis differs from one forensic scientist to another.
☛ Forensic analysis can be prevented by strong influences (political or financial factors).
☛ There is no particular standard to verify the result of the experiment. It requires wide knowledge and intensive study.
☛ Innovation is hindered as the approach is mostly the same.
☛ Misconceptions and ignorance can mislead the experimental analysis.
☛ Maintaining privacy and secrecy of the information gathered through forensic analysis is quite difficult.

Forensic science analysis is not an easy task to accomplish. It involves a lot of hindrances and challenges. Forensic science is not a single independent subject. It is a combination of various subjects like engineering, pathology, linguistics, forensic seismology, forensic toxicology, forensic anthropology, microchemistry, criminalistics etc. The law enforcement agencies are highly dependent upon forensic science to establish justice.

How does a Taser Gun Control the Human Body

admin — Sun, 23 Oct 2011 14:33:20 +0000

A peak voltage of 50kV (50,000 volts) is generated inside the gun, however, it delivers lesser power because of some resistance that is offered by the target medium. When a circuit that produces electrical signals (Taser waves or T-waves) is established, a series of pulses 100 micro-seconds wide are generated inside the gun. The gun generates 19 such pulses per second. By making a simple calculation using these parameters, we can get the average current emitted from the Taser gun, which is 1.9 milliamperes.

The electrical signals from a Taser gun affect the human body by exploiting its skeletal and heart muscles.

Heart Muscles: The heart muscles are made up of interconnected fibers, which are made up of cells. The cell-to-cell resistance is very low and any electrical impulse that strikes a cell can quickly pass to the other cell in very little time. The conduction tissue of the heart is designed to enable smooth functioning of the four chambers of the heart. When a jolt of current at the right frequency hits the heart, a situation known as ventricular fibrillation (uncoordinated contraction of the ventricles of the heart) is created in the heart. Tasers cause this situation inside the human heart.

Skeletal Muscles: When a human brain orders a muscle tissue to contract, an electrical impulse travels down through the motor nerve and terminates at the middle of a muscle fiber. Here, the Taser pulses exploit the skeletal muscle fibers by directly jolting the motor nerves with electricity. The electrical signal from the Taser is converted into acetylcholine and binds with gated-ion channels when it comes in contact with the muscle fibers. The receptors (gated-ion channels) open up, allowing the sodium ions from the surrounding salty fluids to flow into the muscle. We know that movement of electric ions produce voltage. Likewise, this movement of sodium ions into the cells of the muscles, increases the inner cell voltage and also triggers the nearby ion-channels. Thus, a wave of voltage runs between the ends of the muscles which make them contract.

The pulses that are emitted from the Taser gun are designed considering the chronaxie (minimum time required to cause stimulation of a muscle fiber or nerve cell) of the heart and the skeletal muscles. The electric current (1.9 mA) from the Taser gun is far below the danger zone of a healthy human body. A Taser gun can shoot a target which is up to 35 feet away. For civilians the cartridge design is limited to 15 feet. The X12, C2 (civilian model), and the M26 and X26 (police models) are some of the Taser gun models. These guns are expensive and are still a heavily debated topic.

A Look into the Future of Cell phones

Mobile Phone as a Credit Card?
Radio Frequency Identification (RFID) is a very fast growing technology, which uses radio waves to transmit information from a device or a tag. One of the important applications of RFID is near-field communication (NFC) which allows money transactions, and information exchange between devices which have NFC chips embedded in them. A smart phone could be used as a credit card and an ID card, if it has the NFC radio frequency chip, enabled with NFC standards.

4G Mobile Technology
4G (fourth generation) technology is an initiative that aims to move beyond the limitations and problems in the present 3G technology. Some of the enhancement features projected in 4G technology are:
•Higher data rate
•Broader bandwidth
•Smoother and quicker handoff
•Seamless service
•High quality voice communication
•high-definition video
3G technology mobile phones can deliver a data rate of 384Kbps to 2Mbps. 4G aims to reach a limit of 100Mbps for mobile phone users and 1Gbps for stationary users. 4G implementation is quite expensive and is not available in all mobile phones now. It is expected that soon 4G will spread and will be widely used by all mobile phone users.

Mobile Commerce
Mobile phones enabled with Internet services are used by business analysts for mobile commerce. Mobile commerce is defined as “Mobile commerce is any transaction, involving the transfer of ownership or rights to use goods and services, which is initiated and/or completed by using mobile access to computer-mediated networks with the help of an electronic device.” Business-to-business (B2B) and business-to-customer (B2C) are the two important applications of mobile commerce. Mobile commerce technology started to grow rapidly from the year 2000 onwards. Some of the mobile commerce services are mobile banking, mobile marketing and advertising, mobile brokerage, auctions, etc.

Enhanced Authentication
Nowadays, stealing cell phones is a very lucrative business for thieves and culprits roaming in society. It is necessary to protect our devices from them. Voice recognition and fingerprint recognitions are reliable methods that provide security to our device, as it cannot be duplicated. In this technique, the device can be made accessible only after it detects the identity of its owner. The other biometric traits that are usable in cell phones are retinal scan, iris recognition, palm recognition, ear canal recognition, signature, hand geometry and chemical traits such as an odor and face thermograph.

High Pressure High Temperature

The CVD method works using a ‘bottoms-up’ approach utilizing by using carbon atoms as a base to start from. Hydrocarbon groups are broken down inside a low pressure chamber to separate the hydrogen and carbon. The breakdown process typically ionizes these atoms giving the user, control over these atoms. The ionizing process kicks the outer shell electron out of orbit and the whole atom gains a positive charge, which was earlier neutral. These ionized particles can then be accelerated, decelerated and focused dependent on deposition parameters. These ionized carbon atoms are the building blocks for forming diamonds. The substrates where this deposition takes place are heated to around 700 to 800 degree centigrade. The ionized carbon atoms float around and settle on this substrate since they cannot settle down on a low temperature surface. These atoms collect an electron from the surface and become neutral once again. Settled atoms then act as a ‘seed’, where other atoms can settle around and form the required diamond geometry which can then grow into larger sizes. This technique is highly dependent on process parameters like temperature, pressure, gas flow rates, rate of ionization and substrate material.

High Pressure High Temperature

The HPHT technique basically works by simulating the process of diamond formation under the earths crust. The major factors for diamond formation under the earth include carbon source, high pressure and high temperature. In the case of a HPHT model, the high pressure source is provided by multi-sectioned anvils compacting a graphite source. Graphite, as is widely known, is another allotrope of carbon atoms wherein the atoms are arranged in a hexagonal array in a planar arrangement. The high pressure and high temperature arrangement made possible by the anvil and temperature sources convert the planar arrangement into diamond-like formation of the atoms. This approach is typically a top town approach wherein you change the property of a bulk material to tailor it into the form required by the user. This method is comparatively less expensive as compared to the CVD method.

Whatever the method of synthesis, the end result lies in aligning the carbon atoms in a diamond structure formation. Diamond prices, then vary depending upon the formation method of diamonds, whether it is geological, bottoms-up or the top-down approach.

Blowing down the Glass Bubble

admin — Thu, 06 Oct 2011 00:59:19 +0000

Glass artists often compare the similarities in the technique of glass blowing and making artwork using honey or caramel. But with honey or caramel, it is perfectly harmless if the sweet nectar gets into your mouth by mistake. Can you imagine the skill required to blow orange-colored molten glass at a temperature of approximately 2300°F? Well, I have just compiled the detailed steps of glass blowing process for better understanding.
•You start the process by gathering molten glass from a furnace at the tip of your blowing pipe. See to it that the pipe is always held in the downward direction to prevent molten glass from flowing over your hands or towards your mouth.
•Hold the blow pipe with molten glass blob over a marver table and roll to create an elongated cylindrical form. Remember that glass starts cooling down from the moment it is taken out of the furnace. So you might need to do the rolling process quickly and accurately.
•Now, blow some air into the pipe and block the open end of the pipe with the tip of your thumb. Do not shake the pipe so as to form the perfect glass bubble. This bubble gently expands as the air pressure increases within the pipe on account of its blocked end.
•For any malformation of this bubble, use the glory hole to reheat the glass. Blow into the pipe again as mentioned above. You need to be careful that the glass bubble is even all around.
•Use a moistened newspaper to gently turn the glass bubble into whichever shape you want. The moist newspaper helps you shape your glass without burning your hands. Now, gently blow into the bubble using the blow pipe and watch as the glass bubble expands.
•Once done, use your free hand or take help of a knowledgeable accomplice to add a neckline to the bubble using the jack. Make it large enough to avoid shutting off the bubble hole.
•Once the required shape and size of the glass is achieved, use a paddle to make a flat bottom of the glass bubble. This is the stage where you have the option of adding colors to your glass. Reheat the glass if required, using the glory hole.
•Use the tweezers to grip the glass and drop some water at the neckline of the glass bubble. You may tap the blow pipe to separate the glass from the blow pipe or just use the shears to do the same.
•Once done, place the glass in an annealer to cool it down. The time required for setting of glass may vary from minutes to days. You just need to be patient.
Way to go…you have just created your first beautiful piece of blown glass. Do not be dejected if you have messed it up a little bit. It might take years of patient practice and help of a trained expert to master this art. Once done, make sure this priceless piece of personal art gets the best place on your living room mantlepiece.

What is SMS Text Message

admin — Mon, 03 Oct 2011 07:58:08 +0000

The growth of this phenomenon continues to be so exponential that any statistics that are cited become obsolete by the time the ink is dry. Americans spent $42.8 million dollars on mobile devices in 2010, & that figure is expected to increase to $1.8 billion by 2015. Not only do they talk & text with them, but they take photographs, play music & games, surf the net, shop, navigate, & update our online social networks. Cell rings have arguably become the most indispensible gizmo in our lives.
The cell phone, along with its latest reincarnation the smartphone, is the most widely used communication gizmo in the world today. With new technologies expanding its onboard capabilities continuously, there is clearly no slowdown in sight for its global domination.
In this reality they have naturally also become the point of interest of worldwide promotion trends, with advertisers in all industries looking to harness the power of mobile communication. The most basic kind of mobile promotion is SMS Text Message Promotion. With 200 trillion text messages being sent every day in America, this type of promotion is not innovative, it is basically learning to speak the language of our new culture.
SMS Text Message Marketing offers numerous fascinating benefits for your business:
one. Direct communication for your message
Not only that, but it is an instant kind of communication. Potentially a message travels from sender to receiver in a moment of time. Studies have shown that the massive majority of SMS messages are read within minutes of having been sent. Imagine what this means for truly “time-sensitive” offers; there is no longer any waiting for anyone to return near their mailbox, phone or tethered computer.
Text messaging lets you bypass all kinds of traditional obstacles and get your words right to the personal attention of your target audience. The new reality is that the mobile phone is now always present, and always on. So they are speaking about truly “wherever they are” marketing.
two. High deliverability rates
Text messages have much higher success rates in terms of passing spam blockers, and then actually being opened and read, than traditional electronic mail marketing. This is achieved with no higher cost to the sender.
of the great advances that electronic mail brought to marketing was unprecedented capacity for tracking effect and response. No longer did advertisers must wait until the point of sale to assess the impact of their message on their audience. If a person opened an electronic mail, clicked a link, returned for a second look — all this knowledge was reported back. SMS Text Message Marketing offers all these same features.
three. Unprecedented opportunities to capitalize on impulse purchasing
Think about this scenario. When your subscriber is sat at a more traditional PC workstation news in their home or office they have countless things to occupy their attention other than your message: the half done tasks lying on their table, relatives activities, the TV in the next room, the doorbell, and on it goes. Now think about this same person sat in the waiting room of the dentist’s office. None of these other voices are at hand, but their mobile phone goes with them. It beeps. Your text message comes as a welcome mate to distract them in their boredom, and with nothing else to do they look in to your offer. With the rise of mobile payments, their response action can happen right there on the spot.
For all of the reasons they have discussed, SMS text message marketing provides you as a business owner with an invaluable tool. The future clearly is mobile, and businesses that ignore the trend will be at a great competitive disadvantage.
