Top 10 – Proven Oil Reserve Countries

Saturday, January 2nd, 2010

This is a list of countries with proven reachable oil reserves in billions of barrels, and is a rough estimate based on the ability to recover the oil by current technological and economical means.

Saudi Arabia – 262

Saudi Arabia is the largest exporter of petroleum in the world, and plays a leading role in OPEC, which stands for The Organization of the Petroleum Exporting Countries; an international organization made up of eleven oil producing nations.

Canada – 180

Canada’s Athabasca Oil Sands Project is what puts Canada on the map in this list. Current surface mining techniques and in-situ methods to extract bitumen from the oil sands make for an overwhelmingly positive future for Canada’s oil industry.

Iran – 126

Iran’s economy relies heavily on oil export revenues, and as oil prices rise, Iran’s economy improves. Iran is in the process of diversifying by investing some of it’s oil reserves into other areas, such as petrochemicals; and is in the process of creating more favorable climates for foreign investment.

Iraq – 115

According to oil industry experts, new exploration may raise Iraq’s reserves up to 300 billion barrels. This has created global foreign interest to re-establish within the country. The US, UK, France, China, Russia, and Japan all vie for major concessions complicated by unrest in the post-Saddam Hussein era.

Kuwait – 102

Though the loss has been estimated at 2% of total oil reserves, Kuwait has recovered fully from the invasion of Iraq. The KPC, or Kuwait Petroleum Corporation, has grown to become one of the ten largest oil companies in the world.

U.A.E. – 98

At one time an underdeveloped region, by 1985 the UAE had the highest per capita income in the world. The largest areas of petroleum production occur in two of the seven constituent parts of the UAE; these being Dubai and Abu Dhabi. Abu Dhabi qualifies as a oil state in the same sense as Kuwait.

Venezuela – 77

Venezuela is the fifth largest oil exporter in the world, and a founding member of OPEC. Oil output has been hampered at times due to protest and controversy, but the country remains an active contributor to the world supply of oil.

Russia – 60

Russia has the world’s largest natural gas reserves, the second largest coal reserves, and the eighth largest oil reserves. The country is the world’s largest exporter of natural gas and the second largest oil exporter. Reorganization of the Russian Energy Sector has shown improvements in the industry over the last few years.

Libya – 39

Though sanctions against Libya had been removed by United States President Bush and also by The United Nations, some Libyan authorities caution foreign optimism about prospects in the country’s socialist driven economy. Nonetheless, the removal of sanctions allows Libya to drive forward.

Nigeria – 35

Nigeria is the largest oil producer in Africa, and is a major oil supplier to both the United States and Western Europe. Proven oil reserves are expected to be expanded to 40 billion barrels by the year 2010.

Figuring Algebra

Monday, November 2nd, 2009

Algebra is one of the most critical arms of maths that is often introduced to students in Jr. High. Many individuals find the concept of algebra a challenging one to understand. Algebra is one of the complex subdivisions of maths that takes the pupil through a study of structure, relation and quantity.

The Standard Methods

In algebra you will frequently hear the term like variables. This is frequently used when adding and subtracting radicals. When adding or subtracting radicals the radicals must be the same order before you add or subtract them.

As a method of finding the least common denominator by listing the multiples of each denominator and dividing by 2,3,4, and so on. After that you should look at the smallest number. An example is multiples of 5 are 10, 15, 20, 30. Multiples of 6 are 12, 18, 24, 30, and multiples of 15 are 30, 45, 60. So in this example, 30 (5 in to 6) is the smallest number which is common to both the number lists.
If you are supposed to simplify a fraction, it can be done easily by finding a common factor in the numerator and denominator. A common factor is going to be a number that will equally divide into both numbers. An example would be 3 is a common factor for 6 and 12. Three will evenly divide into 6 and into 12. You could also look at 2 being a common factor for 4 and 14. The same division procedure needs to be repeatedly executed until there are no common factors left. This can also be done by finding the greatest common factor of both the numerator and the denominator. You will divide the numerator and the denominator by the greatest common factor instead of the common factor.

Getting Good with Algebra

If you find yourself in difficulty with algebra and can’t seem to find the solution you need. You can use an algebra problem solver that will allow you with the needed assistance. With one of these computer software system you can simply input the figures related to the question and your problem will be solved right away in an illustrative fashion (including the steps). Having access to an algebra problem solver software system can mean the difference in passing or failing. Most pupils cannot afford a tutor and they are rarely around when you need them anyway. With an algebra computer software you will have access to the solutions you need, anytime when essential.

Wind Power Farms

Monday, October 19th, 2009

Given that wind is a naturally occurring, free, renewable resource, the ability to make use of the wind for electricity generation makes it very useful in the current times of rising energy prices. Wind power is best utilised in farms and rural areas.

It may also work in ’suburbia’, but is unlikely to be much use in densely populated areas due to the increased number of obstacles preventing the free flow of the wind. The future of wind technology will be revolutionized by works of individuals who can build their own wind turbine for harvesting wind for energy. In remote locations, wind energy is a cost-effective alternative for grid-extension. But do-it-yourself(DIY) solar and wind energy is not as far out of reach as you may think. Know how to be energy efficient in your own home, and you can save the world. Guides are out there that clearly show you how to build your own systems for less than $200. And I doubt it will be hard with easy to follow instructions. It had been, for the longest time in the past that wind power was seen as a source of getting energy that can be used by men. But we seem to have forgotten that and had resorted to the capitalized struggle into making things that would only run on things that we need to burn. But because of our own doing, we have turned our planet into a microwave that is melting itself. I have been able to make my own wind turbine and solar power generator for a very low cost. Today, my electricity bills have dropped by about 80% and I am able to sell my excess power back to my power company. The guide contains clearly written steps and illustrations that teach you how to set up everything, and contain a list of parts that you will need to start building

Can You Understand Algebra?

Sunday, October 18th, 2009

It is safe to say that algebra is the heart of mathematics. An in depth knowledge of algebra and its basics is required before you could work on other mathematical problems. If someone asks you to calculate the product of 223 and 112, you can easily do it manually or with a computer. But when it comes to exponential (e) of 223 and logarithmic (log) of 112 then most definitely, you will need some kind of algebraic calculator or algebra problem solver. Graphing a circle will be easy for this given formula X2 + Y2 = 4 but when it comes for an inequality like (X-2)2 + (Y-4)2 > 20 then it will be quite harder to plot the graph. In this situation algebra software program can help you immensely since you only need to enter the inequality and graph will be plotted within a fraction of second. These software can easily solve any kind of algebraic, arithmetic and radical expressions of any level of complexity.

Finding Domain and Range of a Function

Now it is very easy to derive the domain and range of functions like Y = X2, you can just tell that X and Y can take any real number from the X-Y plane but have you ever thought of defining the domain and range of log(tan 2x + sin 3x) = cosine(-4)(2x). But thanks to algebra calculators, you can now solve these complex sums in very little time while being able to comprehend each and every step that it takes you to successfully work out the mathematical question.

Coordinate Geometry

Now you can easily find the vertex and directrix and whether parabola opens up or down by just inserting the equation into algebra Application. Addition, subtraction and multiplication of polynomials are quite uninteresting , since they involve lots of terms to manipulate. However, by leaving the job up to algebra calculators, you will be able to get results within a shorter period with 100% accuracy. Solving determinants and matrices of 3×3 or 4×4 order can become very hard since it involves lots of calculation; getting inverse of matrices even more so. However using algebra calculators will make this task much simpler.

So, with the introduction of algebra software systems, the times where you feared the sight of indices, rational numbers or complex equations , comes to an end. If you could not stand geometry, you may even start liking it now thanks to the computerized algebra systems that will automatically solve everything you ever need.

Are Algebra Skills Relevant?

We can say that Algebra is the center of maths. An in depth knowledge of algebra and its basics is required before you could work on more complex mathematical problems. If someone asks you to derive the product of 223 and 112, you can easily do it manually or with a calculator. But when it comes to exponential (e) of 223 and logarithmic (log) of 112 then obviously, you will need some kind of algebraic calculating machine or algebra problem solver. Graphing a circle will be easy for this given formula X2 + Y2 = 4 but when it comes for an inequality like (X-2)2 + (Y-4)2 > 20 then it will be quite harder to plot the graph. In this situation algebra software can help you a great deal because once you enter the inequality in the program, the graph will get drawn automatically within a fraction of second. These kinds of computer software can easily resolve any kind of algebraic, arithmetic and radical expressions of any kind of complexity.

Domain and Range of a Function

Although, working out the domain and range of a function such as Y = X2 can be easily found by considering the number range on the X-Y plane, defining the domain and range of a log(tan 2x + sin 3x) = cosine(-4)(2x) will be very difficult. But now you can solve such critical and complex problems with an algebra calculator without breaking sweat and you will also be getting all the steps as well

Coordinate Geometry

Now you can easily find the vertex and directrix and whether parabola opens up or down by just feeding the equation into algebra Application. In addition, subtraction and multiplication of trinomials, you are more likely to become drained because they require a lot of terms to be manipulated. However, by leaving the job up to algebra calculators, you will be able to get results within a shorter period with 100% accuracy. Solving determinants and matrices of 3×3 or 4×4 order can become very hard since it involves lots of calculation; getting inverse of matrices even more so. However using algebra software will make this task much simpler.

So now you need not to start worrying when you see indices, rational numbers or exponential equations. Parabolas, hyperbolas or ellipses can all be easily graphed within computer algebra systems.

Testing and Indicators Offer Insight into Diagnosis of Mesothelioma

Thursday, June 11th, 2009

Mesothelioma will show a few primary symptoms. The main symptom of pleural mesothelioma is a lack of breath caused by pleural effusion ” the increase of fluid in the membrane, or pleura, around the lung. The second most common symptomis chest pain because the tumor is attacking the chest wall. Symptoms may also include fatigue, loss of weight and night sweats

The most common signof patients with peritoneal mesothelioma, which originates in the abdomen, is the swelling of the abdomen because of fluid accumulation (ascites), abdominal pain, and bowel obstruction.

It is important to note that other afflictions or diseases could be causing these symptoms. But if you have experienced any of these symptoms and have had asbestos exposure, you should see your doctor.

Mesothelioma is problematic to diagnose, because many symptoms are also associated with less serious conditions. Symptoms typical for mesothelioma:

  • Having trouble breathing
  • Lower back or chest pains from a buildup of fluid in the pleura
  • Burning up
  • Nausea
  • Raspy voice
  • Difficulty swallowing
  • Spitting up blood

Self-diagnosis should never be attempted. People suffering from the above symptoms should remain calm and consult a doctor. Performing a biopsy is the standard way to confirm the condition. A pathologist removes a piece of tissue from the suspected area and performs an examination that will result in a very accurate diagnosis. Biopsies are generally not painful.

A CT scan (Computer Tomography is an option if you dont want a biopsy. This is an X-ray procedure where a scanner is moved around the body to snap cross-sectional pictures. Once in a while, a dye is ingested by the patient to help define the images. CT scans have an advantage over biopsies by being easier and non-invasive, and they are known to be an effective diagnostic tool. Beliefs vary whether a biopsy or scan is more cost-effective. If there are abnormalities, a biopsy may also be needed to know if the abnormality is a tumor, and if so, if the tumor is benign or malignant. Pleural mesothelioma can also be diagnosed by taking a sample of fluid from the pleura and testing it for the presence of cancer cells.

Mesothelioma can also be screened and then diagnosed by any of these methods. Screening is when patients who may suspect they are at risk are tested for the condition without displaying any symptoms, to ensure they are not at risk to get the cancer or to catch the cancer early. People who need to be screened include those with a history of asbestos exposure..

Why You Need to Know Algebra?

Tuesday, May 12th, 2009

One of the most popular courses of study institutions have for students learning maths is algebra. Although learning algebra is believed tough, there are a lot of students taking this course of study.

A lot of individuals are not even actually sure what is involved in algebra but it is not awful as a lot of individuals think. Most base algebra include finding least common multiple, factoring difference of cubes and reducing fractions.

When students are studying mathematics, especially at college stage it is very critical for them to employ some planning and also some continuity in learning mathematical constructs from easy to hard ones. There are a lot of college mathematics courses of study at introductory stage that are based around establishing a strong path for the road into higher mathematics as they enable learning the elementary skills that are required.

Who offers assistance?

For helping you in mastering algebra, there is a number of software programs and these include programs such as algebra calculators. A tutor for algebra is also a surefire way to enhancing your algebra skills. The software systems are very good and will assist you with all aspects of algebra including non-linear equations , graphing quadratic inequalities , simplifying fractions with same denominators and on master the basic and advanced topics of algebra.

If you start studying maths from the beginning, it is a good idea to do one of the first stage courses of study as they will teach you the very basic principles and build on that so that you are able to get up to the more complex stage of maths. The beginning topics of algebra teach the pupils the correct approach through the use of a vast number of different examples and methods so this is an ideal starting point for the beginner to algebra .

Troubles With Virtual Tutors

The only problem with maths courses of study is that they sometimes do not follow reasoning in a very logical order and this particularly is the case when you are a student at primary school. A lot of the pupils at school are really very ill-prepared for learning algebra and they are not aware of the basics of this notable branch of mathematics.
