A Bright Future for Solar Energy: a Renewable Energy Source

I was first introduced to solar energy in the movie, Race the Sun with James Belushi and Halley Berry in the lead. It was a story about low- income and under achieving Hawaiian students encouraged by their teacher to join the Solar Car race. In the movie, a car shaped like a cockroach and covered with solar panels used the sun’s rays as an alternative energy source to run the car. Solar energy is the light and the heat from the sun. Solar energy is free and its supplies are unlimited. There are n air and water pollution caused about by using solar energy. But there is still some impacts on the environment although indirect. Photovoltaic cells used to convert sunlight into electricity uses silicon and also produce some waste materials. There are also large solar thermal farms and these farms can also be harmful to the environment and desert ecosystems if not properly managed. Solar energy can be used on different aspects. Solar energy can be used in agriculture. Greenhouses (which is entirely different from greenhouse gas) convert solar light to heat to be maximized in enhancing the growth of plants and crops. Greenhouses has been around since the Roman times and modern greenhouses were built in Europe in 16th century. Greenhouses are still an important part of horticulture nowadays, Daylight systems are also being used to maximize the energy released by the sun. It is used to provide interior illumination replacing the artificial lighting. Daylight systems include sawtooth roofs, light shelf, skylights, and light tube. Daylight systems when they are properly implemented can reduce lighting-related energy consumption by 25 percent. Solar energy can also be developed into solar thermal technologies which can be used for water heating, space heating, space cooling and process heat generation. Solar energy can also be used to distil water and make saline or brackish water potable or drinkable. The solar water disinfection or SODIS involves exposing water-filled plastic polyethylene terephthalate or PET bottles. This process takes a long time, since the exposure time varies on the weather conditions. It requires a minimum of six hours to two days during days with overcast conditions. Currently, there are two million people in developing centuries use SODIS for their daily drinking water needs. Also sunlight can be converted into electricity using photovoltaics or PV. PV has been mainly used to power small and medium-sized things like a calculator powered by a single solar cell. There are homes powered by photovoltaics. Using solar energy for water and space heating is the most widely use application of solar energy. While ventilation and solar air heating is also growing in popularity.

It is well said, that just the knowledge of the instructor is not alone enough to raise interest in the subject matter for the students. It’s the way; the subject area is delivered to its which leads a lot for developing interest in the contents.

What is it?

A short and sweet introduction of Algebra would be a subdivision of mathematics which substitutes letters for numbers; algebraic equation is a scale. The fundamental theories of algebra includes real numbers, complex numbers, matrices and vectors.

The Different Arenas

Algebra in general covers a lot of areas. for example; Multiplying exponents, dividing exponents, Solving fractional equations, Finding Greatest common factor or GCM, Multiplying, Adding, Subtracting fractions and many more.

If the above mentioned domains are already putting butterflies in your stomach, I hope that the definitions to follow will ease your anxiety and give real insight in to the subject matter.

Exponents is a notion that indicates multiplication of identical factors. Fractions on the other hand are used for expressing numbers that are pieces of a whole. Similarly there are other areas too in algebra which are scary by name but equally interesting by their definition and purpose. To put down a few more items - Mixed numbers , Quadratic formula, Graphing linear inequalities, solving compound in equalities, Factoring binomials, and Factoring polynomials; are all algebraic expressions.

Although you may find it obscuring to understand mixed numbers, you may be startled to find out that they are a type of fractions. Graphing linear inequalities states its purpose pretty clearly by its name. Similarly there are many other algebraic areas which are really interesting to work with.

Testing and Symptoms Give Steps into Diagnosis of Mesothelioma

Malignant mesothelioma has a few primary symptoms. Pleural mesotheliomas main symptom is a lack of breath due to pleural effusion ” fluid being built up in the pleura, or membrane, encompassing the lung. Another 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 indicatorof patients with abdomen mesothelioma, which begins in the abdomen, is fluid buildup (known as ascites) in the abdomen causing abdominal swelling, abdominal pain, and bowel obstruction.

Its vital to know 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.

Peritoneal mesothelioma cancer is hard to identify, because many symptoms are also associated with less serious conditions. These symptoms include:

• Shortness of breath
• Chest or lower back pain associated with an excess of fluid in the pleura
• Running a temperature
• Vomiting
• Hoarseness
• Having trouble swallowing
• Coughing blood

Self-diagnosis should never be attempted. Sufferers of the above symptoms should not panic, and should consult their doctor. A biopsy is the primary way the condition is confirmed. A pathologist takes a sample of tissue from the suspicious area and examines the biopsy which results in a very precise diagnosis. Biopsies are typically pain-free.

Another option is a CT (Computed Tomography) scan. A CT scan is basically an X-ray procedure where cross-sectional images are taken as a scanner rotates around the body. 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. Opinions vary whether a CT scan or biopsy is cheaper. If irregularities are detected, 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. Pleural mesothelioma can also be diagnosed by taking a sample of fluid from the pleura and testing it for the presence of cancer cells.

Any of these methods may also be used to screen for mesothelioma. Patients who may think they are at risk but do not display any symptoms are typically screened, to catch the cancer early or to make sure the patient is not otherwise in danger. Patients who have in their past inhaled asbestos, should be screened for mesothelioma.
