The Info Backstage

Wind is produced from the uneven heating of the atmosphere and irregularities in the earth’s surface. The air movement between these areas is what we refer to as wind. Just as we can use flowing water to turn turbines, we can harness the power of the wind with wind turbines to create electricity.

Wind turbines have been in use since the 1920s. Their earliest use was to provide electricity in remote areas that didn’t have access to a large utility company. Today there are fewer areas that are “off the grid” but wind power can now be used to supplement traditional power sources.

Wind turbines can be used individually to provide power for a household, or they can be used in arrays to provide electricity on a large scale. These arrays of industrial sized turbines are called “wind farms” and are usually situated in areas that receive consistent strong winds. Coastal areas, hilltops, and mountain passes are common areas for wind farms.

Thanks to advances in wind turbine technology we are now able to use the wind as an affordable alternative to fossil fuel for producing power. New technologies make turbines more efficient and modern production techniques bring the cost of turbines down.

When used as a supplement for residential electricity, wind turbines are connected to the breaker box provided by the power company. The power produced is available for immediate consumption, and if the wind turbine produces more electricity than is needed the excess is fed back into the utility grid for a credit on the homeowners power bill.

For those interested in living “off the grid” wind power can be used in conjunction with other alternative energy sources such as solar power. These two methods of producing electricity complement each other, when the sun is strong, the wind may be low, and the wind may be stronger on cloudy days.

Also, since solar power is not produced at night, a wind turbine can provide the electricity at this time.

Whenever someone asks me for suggestions on EZ to plant trees and shrubs, I always begin with Arborvitae.

Arborvitae are commonly used evergreen shrubs or trees useful in urban areas where low maintenance and durability is needed. Many cultivars with forms such as being globed in shape, columnar, or narrow pyramidal, tend to be near buildings, doors, and walkways. Other forms which are larger are used for screens and buffers that are planted in rows. The form of arborvitae is small, medium, or large depending on the cultivar. Some reach 50′, others only 3′. Most prefer full sun to partial sun. Planting in dense shade conditions should be avoided. A moist , well drained, loamy soil in full sunlight are ideal conditions for growing healthy arborvitae. These plants will tolerate rocky, clay, urban conditions of heat drought and pollution. The most important pest we have is bagworms which must be controlled to prevent complete defoliation. Some cultivars have multiple leaders which also prove to be a detraction for the plant. Pruning out multiple leaders in some cultivars is a simple remeady. Our most popular Arborvitae is the Emerald Green arborvitae. Many people prefer to spell them Arbor Vitae . It is a bright light green color and narrow in shape. It makes a distinctive and impressive natural fence. It is easy to grow ,plant, and keep in shape.

The Hetz Midget arborvitae is a dwarf globe variety. This is a good choice for along walkways and gardens. This is a tough plant that is easy to install and not going to cost a lot. It will maintain its color in the winter and will withstand snow loads well. We carry these plants in 2 and 3 gal. pots. The prices on these dwarfs vary from $15 to $30 depending on size and quanity ordered.

Another small arborvitae that we grow in pots is the Rheingold arborvitae. This is a small globe shaped plant that has a golden green cast to it in the summer and a bronze winter color. We also have the American Arborvita known as “Tiny Tim”.This arborvita grows in zone 2 – 7. Its is a needled evergreen in the Cupressaceae Family. It will grow in height from a half a foot to 1 foot tall. Its spread will be about 1 to 1.5 feet. This is a plant that requires little work. Selecting quality arborvitae for the home landscape : When you get to the nursery or garden center where you will buy your arborvitae, pick out the healthiest, most robust plants that have no evidence of disease or insect damage. The potting medium should be moist, but not wet, and the roots should well dispersed in the medium. Arborvitae that have roots growing from the drainage holes or circling the top of the pot are less desirable. Many people choose to buy arbs from a mail order company, which is perfectly acceptable. However, realize that most woody plants purchased from mail order catalogs will be shipped dormant and bare root, that is, without any soil attached to the root system. Such plants may be smaller in size because of the expense of shipping. It is important to plant such material immediately upon arrival. Generally it is best to purchase one-year-old material from mail order companies since this material is more vigorous and will transplant better. The larger material that is offered is often composed of the less vigorous plants held over from previous years. Most large sized arbs are balled and burlaped. Don’t buy any arbs bare rooted over 3′ tall. Any plant larger should be balled and burlaped.

We have thousands of arbs and always have hundreds ready for you to pickup. From 2′ to 15′ we have inventory balled and burlaped. Don’t worry about driving long distances to get to us. We are easy to get to near Phila., on a major road, Rt. 313 in Fountainville Pa.. We want to move our stock and will make sure that you go home a happy camper. If you are coming from a long distance, we will give away free inventory that is surplus to our needs. One of our fields is being converted into ball and soccer fields and work will begin Nov. 25 2005. Stock in this field will go cheap. We will stay open til the last dog dies or we sell out. I think we have more stock than what we possibly can sell. You can see our web sites at:

Mesotheliomahas a few major symptoms. The main symptom of pleural mesothelioma is having trouble breathing caused by pleural effusion ” the increase of fluid in the membrane, or pleura, around the lung. The next most common symptomis chest pain because the chest wall is being attacked by the tumor. Other symptoms may include weight loss, fatigue, and night sweats

The main indicator of patients with abdomen mesothelioma, which originates in the abdomen, is fluid buildup (known as ascites) in the abdomen causing abdominal swelling, abdominal pain, and bowel obstruction.

It is important to note that other afflictions or diseases could be causing these symptoms. Nevertheless, you should see a doctor if you have been exposed to asbestos and have experienced any of these symptoms.

Mesothelioma is hard to identify, because less serious conditions also cause similar symptoms. Symptoms typical for mesothelioma:

• Difficulty breathing
• Chest or lower back pain associated with an excess of fluid in the pleura
• Running a temperature
• Nausea
• Raspy voice
• Difficulty swallowing
• Spitting up blood

One should not self-diagnose themselves. People suffering from the above symptoms should remain calm and consult a doctor. A biopsy is the primary way the condition is confirmed. A pathologist takes a small tissue sample from the region that cancer is suspected and performs an examination that will result in a very accurate diagnosis. Usually, biopsies do not hurt.

CT scans (Computed Tomography) are an option to avoid a biopsy. This is an X-ray procedure where a scanner is moved around the body to snap cross-sectional pictures. A patient might have to ingest a dye to help define the pictures. CT scans have the advantage of being non-invasive and easier, and they are recognized as being effective in diagnosis. Opinions vary whether a CT scan or biopsy is cheaper. If there are abnormalities, a biopsy may be needed on top of the CT scan to confirm whether or not the irregularity is a tumor, and if so, if the tumor is benign or malignant. It is also possible to diagnose pleural mesothelioma by testing a sample of fluid from the pleura for 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 make sure they are not in danger or to catch the cancer as early as possible. Patients should be screened for mesothelioma if they have a history of asbestos exposure.

What is Algebra?

Algebra is a wide branch of mathematics that uses generalization by replacing alphabetic characters for numbers. This abstraction is the very reason why most people find algebra scary and too difficult to handle and it is the same reasons why some pupils find it fun to play around with. topics of algebra extend from working with fractions to factoring binomials all the way to finding the y-intercept. In many cases, just as in any other math associated class, students start by adding, subtracting and simplifying algebraic expressions . They then move on to understanding equivalent fractions, finding Least Common Multiples (LCM) and converting fractions to decimals.

Help!!! Exponents, Radicals and Graphing on the Way…

There are numerous higher level topics. Firstly there are exponents. An exponent is the tiny number placed to the right and slightly above a number or algebraic expression. An example is (x + y)³ where the 3 is the power and refers the power to which that number is raised. The above algebraic expression is expressed as, x plus y to the third power. While working with exponents you will oftentimes see exercises that require you to add, subtract, multiply and divide. If you pick up the fundamental principles, you will shortly get down to working with rational and negative exponents and if you think those are not challenging enough, hopefully complex number will spin your head. A radical, simply put, is the undoing of an power. Radical expressions are referred by the symbol “V” and when placed alongside number 4, it is read as square root of 4, which is equal to 2. The opposite exponential equation is 2^2 which is read, 2 to the 2nd power, and equals 4. As with exponents, radical expressions can be added, subtracted, multiplied and divided. Radicals can be changed into powers and exponents back into roots. If you find that exponents and radicals don’t really perk up your interest, you could move on to graphing. The best way to start with graphing is to draw lines and try to work out if they are horizontal, vertical or neither. Does the line have an x-intercept or a y-intercept? Can you find the slope of the line? you master the mathematical art of graphing, you will discover a whole new world full of parabolas and hyperbolas.

The Difficult Areas

Algebra addresses a large number of topics, graphing curves being one of them. This could include charting a circle, graphing systems of radical equations, graphing inequalities or graphing quadratic equations . Exponents is one of the main areas of study. This can range from subtracting exponents, dividing exponents or just using the laws of exponents. Rationalizing, factorizing, matrices, hyperbolas and quadratics all have to do with algebra.

It is commonly agreed that algebra is a tough subject. Nevertheless, in today’s day and age that is not a problem as virtually every student has access to a computer. A student can easily use online mathematics computer programs that instruct and test the user. These software packages also have worksheets to help pupils practice and improve their skills. Online tutors are also available and are easy to reach. The fees can be based on number of hours or per module and this works as if the pupil and the tutor were face to face.

How to Find Help for Algebra

There are a large number of computer software programs that can help students. These computer programs provide bit-by-bit guides to help students through their difficulties. These software programs can help you with your homework, test readiness and even exam readiness! As algebra has a vast number of sub-sections you can select software packages that link to your particular difficulty or problem. This could be complex equations, inequalities, functions, or just graphing. Some software systems also include games and videos that could further develop your algebraic skills.

Algebra calculators are one of the most main tools available for helping your skills in algebra. They can help solve some types of algebraic questions. Mostly these will include questions that have to do with radical equations or fractional inequalities. Various calculators allow you to construct graphs at the click of a button.

Though these software systems and other aids can help many students master a great number of problems, it is important that other resources are also utilized for further enhancing your algebra skills. Using these facilities and cheating would only be a loss to yourself. These software package are ideally used for double-checking your answers of your homework assignments rather than using them to complete the actual tests.
