Hybrid Cars vs. Conventional Cars

Saturday, March 20th, 2010

Today, the question on everybody’s mind is, what is the difference between a hybrid car and a conventional vehicle? There must be some good reason why people are debating whether hybrid cars are worth the money and checking their wallets and savings account to see if they can afford to buy a hybrid car.

There must be a good reason why some other people wouldn’t dream of spending their the money on a hybrid car because they feel their conventional car gets them to wherever they have to go just fine. Here are some of the reasons why someone may decide on a conventional car over a hybrid car.

Hybrid cars are much more expensive than conventional cars: because hybrid cars have a complex internal design, they do still have a fairly hefty price on them, although, conventional cars, which have gotten more efficient as the years have gone on, are quite affordable these days. Many people are selling their older conventional cars in favour of newer, more efficient versions.

They are so inefficient in fact, that some people even give their old cars away. However, since a large percentage of the general population has never owned a hybrid, there aren’t many people selling used hybrid cars yet. Therefore, the average person looking to buy a hybrid would probably have to purchase a new one from a car dealer.

Both a hybrid car and a conventional car use a similar type of battery: a hybrid car and a conventional car both make use of lead-acid batteries that have enough power to turn a small electric motor. These batteries are what you call “gear reduced”. That means that they can turn over this electric motor at approximately 300 rpms. Torque is generated to turn over the engine and the entire process is what starts the main petrol or diesel engine.

But even though a hybrid car uses a lead-acid battery, the battery it uses to drive the car’s electric engine is constructed differently. This kind of battery is known as a ‘deep cycle battery’ and it can be compared to the batteries that are used to power electric fork-lift trucks, milk floats or golf carts.

That’s the main difference between a hybrid car and a conventional car. One person might choose a hybrid car because it makes them feel more secure. For instance, if a person buys a hybrid car, they can feel secure that their car will be less likely to run out of fuel. Another person might not choose a conventional car because the cost of gas doesn’t really bother them that much.

However, a conventional car provides security as well, but of a different sort. With a conventional car, a person can be sure that they can always go to a scrapyard, if they need to replace old parts for their car. On the other hand, those with a hybrid car will probably have to pay some pretty pricey repair receipts if something goes wrong.

The final decision rests0 solely with you. There are certain minor risks associated with both types of vehicles. But if you like to try out new technology, you might consider splurging out on a new hybrid car next time.

The Chinese Lunar Calendar

Monday, February 22nd, 2010

Previous to their implementation of the Western solar calendar scheme, the Chinese almost exclusively followed their own lunar calendar for determining the times of planting and harvesting and festival days. Although people in China today use the Western calendar for almost all business, governmental and practical matters of daily life, the old system still serves as the basis for working out numerous recurring holidays. This coexistence of two calendar schemes has long been acknowledged by the people of China.

However, this does not only apply to China, it also occurs in most other Eastern countries, like Thailand, and most Arabic countries.

A lunar month is determined by measuring the period of time needed for the moon to complete its full cycle of 29 and a half days, a standard that makes the lunar year a full eleven days shorter than its solar counterpart. This difference is corrected every 19 years by the addition of seven lunar months.

The 12 lunar months are further divided into 24 solar divisions characterized by the four seasons and times of heat and cold, all of which bear a close relationship to the yearly cycle of agricultural work.

The Chinese calendar - very much like the Hebrew calendar- is a combination of the solar and lunar calendars in that it strives to have its years concur with the tropical year and its months coincide with the synodic months. It is not surprising that a few similarities exist between the Chinese and the Hebrew calendar.

For example, an average year has 12 months, a leap year has 13 months. An ordinary year has 353, 354, or 355 days, a leap year has 383, 384, or 385 days. When determining what a Chinese year will be like, one needs to make a number of astronomical calculations.

First of all, you have to determine the dates for the new moons. In these cases, a new Moon is the completely black Moon (that is to say, when the Moon is in conjunction with the Sun), not the first visible crescent, as is used by the Islamic and Hebrew calendars. The date of a new moon is then the first day of a new month.

The reason why the majority of countries which had their own calendars had to dump them in favour of the Western, Julian calendar that we use today, is business. First the British and then the Americans ran international business and they used the Julian calendar.Anyone who wanted to work with them had to follow suit. This is why national policy often varies from local custom in Third World countries.

The government desires to deal on the International markets, but the ordinary family in the country can not. So, the government adopted the Julian calendar but the people only pay lip service to it. I live in Thailand and people here do not even use the 24 hour day divided into two halves. Their day has four sections of six hours each and the first part starts at 6AM, not midnight. Therefore, they have four 4 o’clocks a day, for example but no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for example in Muslim countries.

Gifts - 5 Top Tips

Monday, February 8th, 2010

It is a worldwide convention to give gifts for such occasions as birthdays and wedding days, but after that is where the countries start to differ. Britons and people tracing their history back there give gifts on Christmas Day as well.

However, many other Europeans give gifts at Christmas on Saint Nicholas’ Day or December 6th. Non-Christian countries usually give gifts at New Year.

No matter what you do in your country, giving a gift takes thought. The shops are usually full of rubbish at these present-giving times of the year, but there is also a lot of good stuff about, at a price. The alternatives are twofold on the whole.

You can either make something which will be one of a kind, I imagine that this includes personalizing a shop-bought gift or you can think outside of the box, which many people find quite difficult. Personally, I find it difficult, but it does get easier the more often you try it and the better you know the person you are going to give the present to.

Here then are a few ideas which you may decide to take on board ‘as is’, or they may inspire you on to better ideas. As I write, Christmas is coming up and then it is Saint Valentine’s day before you know it. We definitely get lots of of occasions to practice buying gifts in the West!

A Plot Of Your Own: I come from Wales in the UK (is there any other?) and up the way from me a local plot of green-belt land was in trouble. Experts said that it should be planted with trees, but the authorities did not have the funds, so they advertised six feet square plots of land for sale with a sapling of your preference on it.

You also got a title deed, directions and a photo. Furthermore, the tree would be maintained for five years until it was established. I know that this is not the only place that did this and it was almost certainly not the first either, but it makes a good gift for a teenager who is wondering what he or she can do to assist the environment.

The Key To Success: some children and their parents will be grateful for this one. Scour the second-hand shops for an older or even an bizarre money box. Fill the money box up to a certain level with various coins that bring that level up to the value that you want to give, but leave plenty of space for the child to put money in too. Who do you give the key to? That depends on how well you know the child.

Starting A Collection: this is a brave, but good one. If you know the child well or are prepared to take on a commitment (such as a godparent should), you could choose a set of collectables, such as plates, glasses or coins and buy two or three examples to start the collection off. You can add to it every year. Others will be thankful to you too because they will jump on the band wagon.

In The Bag: if your friend is an invalid or just is temporarily in hospital, it is beneficial to provide a wicker basket or a nice bag full of handy items. Choose the items to suit your friend, but everyone might like a writing pad, a pen, a comb or brush, wet wipes or tissues, a small book of verse, a miniature radio with ear plugs, a mirror, straws, a bottle opener, only you know, but you get the idea, I’m sure.

Stamp It: you can buy a large packet of literally thousands of foreign stamps for very little. Buy a stamp album and hinges and you could start a lifelong obsession. It also gives you gift ideas for years to come too.

Biometrics The New Way To Identify Individuals And Create Better Security For Your Business or Even Your Home

Tuesday, February 2nd, 2010

Biometrics is, generally, the analysis of what can be measured of your biological features. When it comes to computer security, biometrics has to do with certification techniques that utilize differentiating physical features that can be automatically affirmed.

Biometrics has fast come out as a promising technique for authentication and has already found usefulness in quite a few hi-tech security fields. It is this exceptional aspect of the technology that we would like to center on. We will attempt to depict how well biometrics can be utilized for security and certification in different places.

A very large thought among the multitudes is that, Biometrics is available only for the rich and individuals with loads of cash. But that is a long way from reality. Biometrics other than being very efficient, is also very cost-efficient.

Employing biometrics for discovering and certifying many individuals, offers some unequaled advantages. Exclusively, biometric identification provides an identification on an intrinsic part of a persons body. Soon to be relics, similar to smart cards, iron based magnetic cards, physical keys, and so on, can be stolen or left at home. Keywords might be forgotten or observed.

Fingerprint electronic scanners are the most normally applied biometric devices. They made there way into the mainstream several years ago, when producers started designing the technology into laptops and normal computer keyboards, along with providing stand-alone designs for a variety of security applications.

A persons prints remain the same throughout life. In over 140 years of print comparison worldwide, no two individuals prints have ever been encountered to be identical, not even those of identical twins. Good fingerprint readers have been put in PDAs like the iPaq Pocket PC, so the scanning technology is also unproblematic. Might not operate in industrial applications due to the fact that it needs clean hands to operate properly.

Lets take a look at voice biometrics. Comparable to face recognition, voice biometrics provides a way to verify a persons identity without the individuals knowledge. It is easier to take advantage of (by using a recording of a persons voice), it’s not possible to trick an analyst by faking another individuals voice.

To sum up, biometrics has become available to every person at all ranges of prices.

Calendar? - But There Are So Many!

Saturday, January 23rd, 2010

In the West, we tend to think that there is only one calendar, but there are dozens of them around the world. And what is more, there were almost certainly hundreds of them previously. All defunct now either because ours is more accurate or because theirs did not fit in with our commercial way of life.

But that does not mean to say that people do not still use those old-fashioned, defunct calendars. Oh, no! Governments have given up their old, traditional national calendars, but in general, country folk still refer to them, even if they can no longer get hold of a printed version. I cannot go into all the calendars here, but I will mention half-a-dozen of them.

Lunar Calendar - There is some evidence that early man used marks on bone to track or denote the passage of time 25,000 years ago, almost certainly measured by the Moon’s phases. A calendar can be created based on the lunar cycles; it creates a year of twelve months (the word ‘month’ is from the word ‘moon’), but only 354 days, that is, eleven short of the time it takes the Earth to revolve around the Sun. The Chinese still use a variety of the lunar calendar but they resolve this issue by inserting extra moths every now and then to bring ‘time’ back into alignment with the Sun.

Solar Calendar - The ancient Egyptians were the first people to employ a Solar Calendar, although it could justifiably be called a stellar calendar. The new year began for them when Sirius, the Dog Star, the brightest star in the night sky, rose in the same place as the Sun. This more often than not coincided with the flooding of the Nile. This calendar was of 365 days; twelve months of thirty days and five holy days. Therefore, it was only one quarter of a day off the true year. However, this meant that slowly but surely, the new year did not concur with the flood. Scientists have worked out that this calendar was adopted in either 4241 BC or 2773 BC.

Julian Calendar - In 46 BC , Julius Caesar realized that a number of parts of the empire were using different calendars, so he ordered the dating system to be unified. Sosigenes came up with a calendar of 365 days with an extra day every four years. Therefore, in 46 BC, the longest year on record, Caesar added days to the year to bring it back into alignment with the seasons. 46 BC was 445 days long! The immensity of the Roman Empire ensured that this calendar was the defacto calendar of the Western world.

Julian Day Count - In 1582, Pope Gregory XIII instituted a new calendar, but the year after that Joseph Justus Scaliger developed a system of counting days, not years. It starts with 1 on January 1st 4713 BC. On this date the Julian and the lunar calendars and the Roman tax dating system all coincided; something that will next happen in 3267. January 1st 2001 was Julian day 2,451,913

Gregorian Calendar - from at least 730 AD, it was noticed that the year from vernal equinox to vernal equinox was short of the 365.25 days in a year. This had the consequence that the date of Easter was moving back. So he dropped 10 days from 1582 by jumping from October 4th to October 15th and proclaiming that century years would only be leap years if they were divisible by 400. Consequently, 1900 was not a leap year, but 2000 was. This is the calendar we still use today.

What Is a Fly Fishing Calendar?

Monday, January 11th, 2010

Are you asking yourself what the best times to try to plan a fly fishing trip are? Well, when we talk about a fly fishing calendar, we are not quite referring to a printed calendar that you can hang on your wall. We are talking about targeting and specifying the right times to fish and the right places at which to fish.

The main thing you have to think about when you are considering drawing up a fly fishing calendar is: when will the water be at the optimum temperature? That is, the temperature that is best for catching fish. The right time to go fishing will depend on the region that you are looking at for your fly fishing trip.

In some places, such as California, the fishing is pretty good all the year round. While in other locations, like Washington, you will have to stay away from the water in the winter as the freezing temperatures will stress the fish and they will not be as plentiful.

Generally speaking, the fly fishing calendar shows that the best fly fishing is in the spring and summer periods. Early autumn will also find some locations showing good fishing as well. Almanacs can be useful to guide you towards the best fishing times and places as can continuously updating Internet web sites that are run by keen local fishermen.

Many locations will give weekly, and sometimes even daily fishing intelligence on their websites. They can tell you where the fish are biting and where the best locations in the river are to cast your line. They generally keep these fields of their web sites up-to-date pretty frequently. So you can get quality reports just by looking at what other anglers have to say about their fishing experiences.

Usually, fish like warmer water, although, there are other species like salmon and steelhead that thrive in colder water. However, in general, warm water will attract more fish. Nevertheless, if the water is too warm, the fish will be sluggish and will swim to locations where the water is cooler.

The fly fishing calendar used most often by experienced fishermen has been compiled over a long period of time. They expend a considerable quantity of effort to estimate where and when the best fishing will take place. Then they share it with others. That is one of the best things about fly fishing - the camaraderie and the sharing that can come about because of a mutual affection for the sport of fly fishing.

You can compile your own fly fishing calendar with a little time and effort. Just do your homework and keep plenty of notes. When you notice a trend, you will know that it is time to go fishing! Then you should be sure to help your fellow anglers by passing on the information via a local club or the Internet, if you are talented at it, because others will be trying to work out what you already know. You know that most fly fishermen would do the same for you, do you not?

Minor Holidays And Occasions In The USA

Sunday, January 10th, 2010

Hereunder is a list of minor holidays and occasions in the United States. Some of them are virtually unknown, and others are fairly obscure.

April Fools’ Day - (April 1): the day for practical jokes (only before noon in the UK). Its origins are obscure, but it bears a resemblance to an ancient Roman festival for the goddess of nature.

Arbor Day - (last Friday in April): devoted to trees and their conservation. It is held on December 22 everywhere else in the world.

Armed Forces Day - (third Sunday in May): a day to honour the US armed forces.

Citizenship Day - (September 17): replaced Constitution Day in 1952 by presidential proclamation.

Daylight-Saving Time: was first proposed by Benjamin Franklin in 1784, but became the Uniform Time Act in 1966. It is not observed in Hawaii, the Eastern Time Zone of Indiana, most of Arizona (except on the Navajo Reservation), American Samoa, Puerto Rico, the Virgin Islands and Guam.

Election Day - (Tuesday after the first Monday in November): presidential elections are held in years divisible by four and elections for all members of the House of Representatives and one-third of the Senate in years evenly divisible by two.

Fathers’ Day - (third Sunday in June): was first observed in West Virginia in 1908, but this distinctively American holiday was not made official until 1972.

Flag Day - (June 14): was first celebrated in 1877, which was the centenary of the adoption of the modern design. Truman passed the Flag Day Bill in 1949.

Groundhog Day - (February 2): on this day the groundhog looks out of his burrow. If he sees his own shadow there will be six weeks of Winter to follow, otherwise Spring is just around the corner.

Halloween - (October 31): All Hallow’s Eve is the day before the feast of All Saints. It started as a pagan custom honouring the dead and a celebration of Autumn. ‘Trick or Treat’ is purely American with no historical foundation.

Kwanzaa - is a secular observance by African-Americans to commemorate their African heritage. It begins on Dec.26th when a candle in a candelabrum is lit every day for seven days. It was first practiced by Maulana Karenga in 1966.

Mothers’ Day - (second Sunday in May): was conceived by Anne M. Jarvis of Philadelphia as a way for children to pay homage to their mothers. It received presidential proclamation in 1914.

National Maritime Day - (May 22): was proclaimed in 1935 to memorialize the SS Savannah’s first successful transatlantic crossing by a steamship in 1819. It is also a day of remembrance of merchant mariners who died in defense of their country.

National Teachers’ Day - (Tuesday of the first full week in May): is when students are meant to honour the teaching profession.

St. Patrick’s Day - (March 17): has been borrowed from Ireland where it is their national saint’s day.

St. Valentine’s Day - (February 14): was originally to honour two saints martyred by Emperor Claudius (214 - 270), but has been dedicated to lovers since the Middle Ages.

Susan B. Anthony Day - (February 15): Anthony (1820 - 1906) worked for women’s rights and suffrage.

United Nations’ Day - (October 24): commemorates the ratification of the UN Charter in 1945 by the then five permanent members of the Security Council.

Marketing To The Masses

Thursday, January 7th, 2010

If you were to create a self-cleaning textile, the world may want to beat a path to your door to buy some from you, but first of all they will have to know that the fabric exists, that it is available for purchase, and they have to be aware of where your door is. This means advertising.

There are two types of advertising: institutional and product. Institutional advertising promotes the name of your business in general and product advertising markets a product or range of products or services. The sort of publicity that a company requires, depends on the products or services that it provides.

Moreover, some kinds of advertising lend themselves better to institutional advertising rather than product advertising. For example, a shop sign, a sign-written van or a promotional calendar are better suited to institutional advertising, while a newspaper or magazine advert would be better for advertising the latest special offer.

There are few facts and figures available that reveal the astonishing growth of the mass consumption society as well as those dealing with the expansion of the advertising industry. For instance, prior to the Second World War, US average annual expenditure on advertising per year had been about $2 billion for decades.

In 1950, as the post-war economy started to pick up , American businesses spent $5.7 billion to advertise its goods and services. By 1960, that amount had doubled to $12 billion. By 1970, American business was spending $20.

Between 1970 and 1990, as the children Baby Boomers became adults and started earning and spending, advertising expenditure went through the roof, so that by 1986, it had reached $100 billion.

That phenomenal rate of increase could not be maintained, but by 1999, total expenditure on all kinds of advertising exceeded $215 billion . The latest available figures are for 2007 and they stand at $280 billion.

In 1999, nearly 60% of all advertising dollars were spent on adverts in newspapers, magazines, on the radio and on TV. By 2007, that figure had fallen to about 54% as the Internet started to have an effect on advertising trends. These trends are expected to continue as every firm is expected to have its own web site these days.

The nation’s largest advertisers are the manufacturers of cars, food, soft drinks, tobacco and beer and they filter most of their expenditure through about 13,000 advertising agencies., who normally create the ads and acquire the space or air time from the media too.

These agencies have been transformed over the last decade by mergers. The most successful advertising agencies these days are huge international concerns. WPP, the largest advertising agency in the world, billed $37 billion in 2008 and had this to say about itself:

“Our total revenue in 2008 surpassed that of all our competitors, regaining the No.1 worldwide position for the third time”.

An Introduction To Astronomy

Tuesday, December 29th, 2009

Despite the fact that astronomy is the oldest science, it is still at the forefront of not only scientific thought, but also that of the public at large. Who hasn’t gazed up at the galaxy while walking home late at night and wondered? Having said that though, the ancient people of definitely the northern hemisphere, but probably both hemispheres, knew the movements of the stars and planets more profoundly than most of us do nowadays.

They understood then, thousands of years ago, that the majority of stars appear to rise in the Eastern skies at night and travel on circular paths. They also noticed that some ’stars’ were ‘wanderers’ (we call them planets) and that sometimes they went ‘against the flow’.

They also named groups of stars that we now call constellations or even galaxies and knew that those visible in the winter were not the same as those visible in the summer.and that others were visible all year round. The average common man of 5,000 - 10,000 years ago almost certainly knew more about the movement of the celestial bodies than the average common man of today does. (I mean men and women here, of course).

They learned how to calculate or at least locate the extremities of the sunrise and went to extraordinary lengths to mark those positions with huge stone structures, such as Stonehenge in the United Kingdom, probably to facilitate the location of certain positions of the sun or other planets or stars, which may have been important to their religious beliefs or crop cycles.

In 1609, Galileo invented the first artificial device for studying the stars and planets. It was the first astronomical telescope and through it he was able to observe things millions of miles away that no one had ever seen before. Because of the deductions he drew from his observations, he clashed with the Roman Catholic Church and was often in serious danger for his life, so radical were his discoveries.

But humankind was not to be intimidated, and since then we have gone on to build ever bigger and ever better astronomical telescopes through which we can even detect radio waves, microwaves, X-rays, infrared waves and gamma waves from outer space. Forty years ago, we even travelled to our Moon. and we have sent rockets to eight of the nine planets in our Solar System, as well as to quite a few comets and asteroids.

Where are we going next? That decision was always up to the government of the United States and the old Soviet Union, but now there are other players in the field. What will China or India want to explore with their possibly slightly different outlook on life? Or will it be just a question of financial benefit?

The world may be in a state of change and power may be shifting from its traditional seats, but it has not diminished interest in questions that scientists think can only be answered in space. These are exciting times in the science of astronomy, but then man has always found astronomy exciting.
