Start With a School Radio Station

My 15-year-old nephew asked me, “How and where to practice and develop one of the working skills during school time?” My first thought, at that moment, was “College radio station”.

At 16, I joined my college radio station and began my job as an editor for an online music program. From that day, I have become acquainted with terms such as noise, sound, broadcast, frequency and so on. Luckier than many people, with that job, I could earn money for my living, besides gaining very much experience and building up many good relationships which can support my current and future career. And with such experience, now, I can give advice to my nephew or any youth who wants to start a career and develop their skill, knowledge in working.

Well, let me think about what we need for a college radio station. If just listing out, we might think that it’s too simple and easy: a studio, or source of program, and the   transmission  lines. If you are beginners, don’t think you can do much and all but step by step. It was really difficult at that time when we began with various odd pieces of equipment. We started using the easiest means of  transmission  by broadcasting in the school canteen, in classes. And later, we added more ways to reach the audience. We concentrated on serving our school and at the same time extended to other colleges in the same area. Actually, the running of our school radio station was based on fund-raising and sponsorship money. Besides some necessary equipment such as Mini-discs, computers, recorders, we faced a bigger problem for a long time looking for an old, affordable multi-track mixer. We didn’t have the advanced and efficient equipment to support our work.

The first broadcasting show of ours was a two-hour program divided into 3 smaller sections. The first one was “Hello Morning” with 3 tiny bulletins of 3 to 5 minutes each. In these bulletins, we presented all good and happy news. The second section was “Music Dedication Program”. We compiled a few collections of music and one by one was presented everyday. The third one was “School loud speaker” during which we announced important events of the school for the following week. Day by day, the program was extended and the coverage of the program was enlarged.

We received more orders from many schools for radio storytellers, puppeteers, live music programs, music festivals, and etc. The students who worked in the radio station were really in situation in which we could practice and develop the skills of drawing up plans, solving problems, devising strategies and many more. Two years later, our radio station was presented with a big gift from a local station: a voice changer software and a music editor software. These advanced softwares helped us handle our job properly. Instead of needing many students to join in dubbing for a story or a drama, now, we just need two “technical operators” and two students to make the dubbing. The old weak multi-track mixer was “retired” and the music editor.

We learnt how to apply these efficient tools in work. Of course, we found them very useful and interesting. We could easily record, remix music, add sound and effects, change one voice into many others. These jobs used to require many people and much time . However, applying our computers and these softwares, we could do the job well with just 4 or 5 people.

We spent much time, thought and labor in this extra-curriculum job, but we loved it. We made school lessons more interesting and exciting. We created a different way for children to gain experience and helped them make a presentation in a new way. We made a radio program which was considered the “voice” of students, pupils in the school. We sent meaningful music messages to friends, teachers, and so on.

I join my current company, a provider of voice changer and music editor softwares, because of many reasons. One of these reasons is that I want to support many college radio stations. My friends who used to work with me in our school radio station are all having good jobs in professional.

We are very happy to give advice and guidelines to youth in starting a school radio station or a home music studio.

One of the first advices from me is that “Don’t wait until tomorrow what you can do today”. Seize any chance you have, start with your dream, step by step, and you can see a clearer road for your future.

Different Forms of Candida and How it Effects Erectile Function?

The Different Forms of Candida

There are 20 different forms of Candida, the most common being Candida Albicans. These microscopic organisms normally live on the surface of our body without causing any kind of infection or disease. However, under certain extraordinary circumstances, the population of these fungi grows so rapidly that they become the agents of yeast infection or Candidiasis. Thrush, diaper rash, nail-bed infection, vaginal yeast infection and pulmonary candidiasis are some diseases caused by Candida. Yeast infection is mostly prevalent in women; men generally contract oral yeast infection. Penile Candidiasis, or yeast infection that affects the erectile function is quite rare.

Under what situations does Candida start effecting erectile function?

Diabetes- Diabetic men usually have elevated sugar levels in their urine. This makes them the ideal candidates for yeast infection of penis. A large amount of sugar in the urine provides a feasible environment for Candida to grow and multiply in the penis and disrupt the erectile function.

Antibiotics- Prolonged use of antibiotic kills the bacterial flora that is typically present in the penis. In the absence of natural flora, the penis becomes susceptible to infection caused by Candida.

Low immunity- Often, conditions like chronic stress, HIV, hypothyroidism and Lyme lower the immunity of the body drastically and make the penis vulnerable to Candida attack.

Sexual transmission- Having sexual intercourse with a woman who has vaginal yeast infection increases the chances of developing penile candidiasis, which can disturb erectile function dramatically.

What are the symptoms of penile yeast infection?

Frequently, penis yeast infection doesn’t affect the erectile function. In such a case, it is very difficult to detect penile candidiasis. The general symptoms of the disease are excessive itching, particularly on the head of the penis, which can lead to irritation, soreness and redness. In severe cases, small blisters might also appear which is accompanied with a clumpy discharge that is white in color.

The bad thing about penile candidiasis is that its symptoms are very similar to that of genital herpes. As soon as you detect the symptoms, contact your physician immediately to ascertain whether erectile dysfunction is caused by penis yeast infection or genital herpes.

What are some remedies to overcome the adverse effects of Candida on erectile function?

The two drugs that are regularly used for the treatment of penis candidiasis are ketaconazole and fluconazole. These medicines produce their own set of side effects. For this reason, natural remedies should also be tried like yogurt, aloe vera, garlic paste, apple cider vinegar. These can be applied on the affected area for instant relief.

In addition to treatment, certain precautions are also necessary. For instance, if you or your partner is nursing a yeast infection of genital organs, it is advisable to practice safe sex. Furthermore, avoid wearing clothes that are tight at your crotch and keep your genital area absolutely clean and moisture free. Besides these, make requisite dietary changes like start taking pro biotic supplements and Vitamin C in your daily diet.

Efficiency of Candida diet against Candida that causes erectile dysfunction

Candida diet can also prove to be quite effective. While following a Candida diet, you have to avoid eating foods that are rich in carbohydrates. Chicken, meat, non-starchy vegetables, shell-fish, and nuts are found to be very helpful in the treatment of a penis yeast infection. Likewise, you should also avoid foods that are a rich source of yeast like bread, mushroom, cheese, tomato paste, vinegar, and so on.

Concluding words

Penis candidiasis is absolutely treatable. Seek medical advice at the onset of the disease, follow the instructions carefully and try to adopt a healthy and hygienic lifestyle. Switch over to a Candida diet and apart from tried and tested medication, try out natural remedies too. Moreover, keep away from all kinds of stresses and tensions. Practice yoga, meditation and other stress management techniques to overcome all the strains and stresses of your life.

Functions of Minerals

When reading of nutrition and health, minerals and trace elements are often mentioned. We respond by eating lots of fruits and veggies, and maybe a vitamin supplement. We never doubt the validity of needing these things with names from the periodic table, but have you ever stopped and wondered what exactly it is they do for us? Or for that matter what are they and where do they naturally occur? Well you can stop lying awake nights, wondering about this!! Processed food cannot provide the services in the following list:

CALCIUM: Critical for many biological functions, including nerve   transmission , fat and protein digestion, muscle contraction, healthy teeth and bones, blood clotting, nerve functions, and more.

SODIUM: Muscle contraction, fluid balance, cell life and potential, and numerous other functions.

ZINC: Enzymatic reactions, reproductive health, growth and development, immune functions.

Why Are Metals Good Conductors?

Different metals are often employed for various applications because they are known for being good conductors of both heat and electricity. All of the appliances that we find in our homes and workplaces, such as kettles and computers, use metal for one reason or another. But why are they such good conductors? How does it all work?

Generally, atoms will tightly hold onto their electrons, not allowing them to move very much (if at all). In metal, however, atoms hold onto their electrons more loosely, allowing some of them to even be free moving. This is because the electrons form a metallic bond of sorts with each other, creating a moving sea vibrating electrons. They drift aimlessly through the metal, helping to give it it’s various properties, including strength.

Electrical conductivity

This term refers to a metal’s ability to conduct an electrical current, such as in a refrigerator or television. The outer electrons of the atoms are loosely bonded and are free to move through the material. When an electrical current is applied to a metal, it causes the free moving electrons to flow, which allows the current to pass through and be moved on.

Thermal conductivity

This term, on the other hand, refers to a metal’s ability to conduct heat, such as in a toaster or heater. The electrons nearest the heat source begin to warm up, causing them to vibrate fairly fast. In colliding with the cooler, slower moving electrons around them, the hot electrons transmit this heat energy on. Metal is such a good conductor of heat because their electrons are packed so closely together, allowing the vibrations to be passed on very quickly.

Metals are quite often cool to the touch, causing many people to believe that they are actually good conductors of cold, not heat. This, however, is a common misconception – metals are able to quickly absorb heat from their surfaces, including from human skin. It is this loss of heat that causes metal surfaces to feel cold underneath our hands.

When people ask why metals are good conductors of both heat and electricity, the short answer is because of the way their electrons are able to freely move around. To fully get into the specifics of how each element is effectively conducted by different alloys, you would probably have to attend physics classes in order to understand the processes. Having a basic understanding, however, should be enough to show why metal is so useful.

Dog Health Concerns and Common Diseases

Dogs are truly man’s best friend. These loyal, loving, protective and playful creatures have served beside man for thousands of years with an undying and relentless devotion. It’s hard to repay such a service of love, commitment and duty. When put to the basics, we provide our dogs with shelter, healthy nutrition, exercise and friendship. However, a dog’s health and well-being sometimes goes beyond the basics, requiring an owner with an eye for disease risks and proper veterinary care.

If you’re a dog owner, you should make sure your animal sees a qualified veterinarian on a regular basis. The range of diseases, parasites and genetic conditions that dogs can succumb to is vast, so it’s important to keep up your pet’s vaccines, stick to regular check-ups and also know what to look for.

Keep reading to learn about some of the most dangerous and fatal diseases that can afflict your beloved pet along with effective prevention methods.

1. Canine Distemper Virus (CDV)

CDV attacks the respiratory, gastrointestinal and central nervous systems. The disease is contracted through contact with other infected dogs and can be fatal to both young and old dogs. Symptoms include vomiting, diarrhea, fever, shivering, redness around the eyes, loss of appetite, weight loss, seizures, thickened footpads, cough and a discharge from the nose. There is no specific treatment, but sometimes antibiotics can be effective. However, a vaccine exists and should always be administered.

2. Canine Adenovirus or Infectious Canine Hepatitis (ICH)

Infectious Canine Hepatitis (ICH) is an acute liver disease, and highly contagious. The virus is transmitted through bodily fluids like urine, eye or nose secretions. Young and old dogs can be affected by ICH, but puppies are at a higher risk. Symptoms include fever, loss of appetite, vomiting, jaundice and corneal edema, though a blood test is needed to make a final diagnosis. Many dogs recover, but it’s best to prevent ICH through a simple vaccination.

3. Para Influenza or Tracheobronchitis (aka Kennel Cough)

The common name for Tracheobronchitis is Kennel Cough because of its propensity for spreading in close quarters, such as in a boarding kennel. It’s highly contagious and attacks the dog’s upper respiratory system. Like bronchitis in humans, the symptoms are coughing, snorting, hacking and sometimes fever. Kennel Cough can be treated with antibiotics or prevented through vaccination.

4. Rabies

Rabies is not just a dog disease; it will affect all mammals that are not vaccinated against the disease. Rabies directly attacks the brain and the prognosis is often deadly. This common disease can be easily prevented through vaccination. In many states, vaccination for domestic pets is absolutely mandatory.

In short, keep your dog healthy by making sure it gets regular vaccinations. Almost all diseases are preventable.

Factors Affecting Consumer Behavior

Consumer behavior refers to the selection, purchase and consumption of goods and services for the satisfaction of their wants. There are different processes involved in the consumer behavior. Initially the consumer tries to find what commodities he would like to consume, then he selects only those commodities that promise greater utility. After selecting the commodities, the consumer makes an estimate of the available money which he can spend. Lastly, the consumer analyzes the prevailing prices of commodities and takes the decision about the commodities he should consume. Meanwhile, there are various other factors influencing the purchases of consumer such as social, cultural, personal and psychological. The explanation of these factors is given below.

1. Cultural Factors

Consumer behavior is deeply influenced by cultural factors such as: buyer culture, subculture, and social class.

• Culture

Basically, culture is the part of every society and is the important cause of person wants and behavior. The influence of culture on buying behavior varies from country to country therefore marketers have to be very careful in analyzing the culture of different groups, regions or even countries.

• Subculture

Each culture contains different subcultures such as religions, nationalities, geographic regions, racial groups etc. Marketers can use these groups by segmenting the market into various small portions. For example marketers can design products according to the needs of a particular geographic group.

• Social Class

Every society possesses some form of social class which is important to the marketers because the buying behavior of people in a given social class is similar. In this way marketing activities could be tailored according to different social classes. Here we should note that social class is not only determined by income but there are various other factors as well such as: wealth, education, occupation etc.

2. Social Factors

Social factors also impact the buying behavior of consumers. The important social factors are: reference groups, family, role and status.

• Reference Groups

Reference groups have potential in forming a person attitude or behavior. The impact of reference groups varies across products and brands. For example if the product is visible such as dress, shoes, car etc then the influence of reference groups will be high. Reference groups also include opinion leader (a person who influences other because of his special skill, knowledge or other characteristics).

• Family

Buyer behavior is strongly influenced by the member of a family. Therefore marketers are trying to find the roles and influence of the husband, wife and children. If the buying decision of a particular product is influenced by wife then the marketers will try to target the women in their advertisement. Here we should note that buying roles change with change in consumer lifestyles.

• Roles and Status

Each person possesses different roles and status in the society depending upon the groups, clubs, family, organization etc. to which he belongs. For example a woman is working in an organization as finance manager. Now she is playing two roles, one of finance manager and other of mother. Therefore her buying decisions will be influenced by her role and status.

3. Personal Factors

Personal factors can also affect the consumer behavior. Some of the important personal factors that influence the buying behavior are: lifestyle, economic situation, occupation, age, personality and self concept.

• Age

Age and life-cycle have potential impact on the consumer buying behavior. It is obvious that the consumers change the purchase of goods and services with the passage of time. Family life-cycle consists of different stages such young singles, married couples, unmarried couples etc which help marketers to develop appropriate products for each stage.

• Occupation

The occupation of a person has significant impact on his buying behavior. For example a marketing manager of an organization will try to purchase business suits, whereas a low level worker in the same organization will purchase rugged work clothes.

• Economic Situation

Consumer economic situation has great influence on his buying behavior. If the income and savings of a customer is high then he will purchase more expensive products. On the other hand, a person with low income and savings will purchase inexpensive products.

• Lifestyle

Lifestyle of customers is another import factor affecting the consumer buying behavior. Lifestyle refers to the way a person lives in a society and is expressed by the things in his/her surroundings. It is determined by customer interests, opinions, activities etc and shapes his whole pattern of acting and interacting in the world.

• Personality

Personality changes from person to person, time to time and place to place. Therefore it can greatly influence the buying behavior of customers. Actually, Personality is not what one wears; rather it is the totality of behavior of a man in different circumstances. It has different characteristics such as: dominance, aggressiveness, self-confidence etc which can be useful to determine the consumer behavior for particular product or service.

4. Psychological Factors

There are four important psychological factors affecting the consumer buying behavior. These are: perception, motivation, learning, beliefs and attitudes.

• Motivation

The level of motivation also affects the buying behavior of customers. Every person has different needs such as physiological needs, biological needs, social needs etc. The nature of the needs is that, some of them are most pressing while others are least pressing. Therefore a need becomes a motive when it is more pressing to direct the person to seek satisfaction.

• Perception

Selecting, organizing and interpreting information in a way to produce a meaningful experience of the world is called perception. There are three different perceptual processes which are selective attention, selective distortion and selective retention. In case of selective attention, marketers try to attract the customer attention. Whereas, in case of selective distortion, customers try to interpret the information in a way that will support what the customers already believe. Similarly, in case of selective retention, marketers try to retain information that supports their beliefs.

• Beliefs and Attitudes

Customer possesses specific belief and attitude towards various products. Since such beliefs and attitudes make up brand image and affect consumer buying behavior therefore marketers are interested in them. Marketers can change the beliefs and attitudes of customers by launching special campaigns in this regard.

About Purchasing Wipes for Your Gym

Your gym is a resource for people who want to stay in shape or improve their body and health. It can be a haven for people who love to work out and come to exercise classes, and a place for people to meet, socialize and learn about health and nutrition. Your gym, in other words, is more than just a business- it can provide a lifestyle for your clients. In order to manage your gym efficiently and to help ensure that customers like coming there, it is important to maintain your gym and keep it clean at all times. It is also important to offer conveniences to your customers that they will appreciate. One way to both offer a benefit to customers and to help keep your gym clean is to purchase wipes for your gym.

Wipes for Your Gym

When you purchase wipes for your gym, there are a few different kinds of wipes that you should consider. Perhaps the most obvious type of wipes to buy are gym wipes. Gym wipes are designed for cleaning gym equipment between users. Your customers can grab a gym wipe from a convenient dispenser and wipe down the equipment so that it is clean and dry for the next person who wants to make use of the machine.

Gym wipes serve many important purposes in the gym environment. They allow for the machines to stay clean and safe to use, and they help customers to feel more comfortable making use of the equipment. No one wants to grab sweaty equipment that someone else has just been using without wiping it down first, and gym equipments make this easy. Equipment that is slick with sweat can also be dangerous, so gym wipes help to make your gym a safer place. Finally, because the equipment is cleaned more frequently with gym wipes, it will always appear clean to perspective members visiting the gym and to members who want a pleasant environment at the gym. Cleaning at the end of the day will be easier as well, since the machine is already clean from being wiped down with gym wipes.

In addition to gym wipes, you may also wish to purchase antibacterial wipes or hand wipes to keep around your gym. Like gym wipes, these have many purposes and many benefits to customers. For one thing, they can help to stop the transmission of germs. When people use gym equipment and sweat on that equipment, they leave behind more than just their perspiration- they also leave behind any bacteria, viruses or other organisms that were on their hands or body. This can cause other patrons at the gym to be exposed to these disease-causing organisms. Recent outbreaks of swine flu and other contagious diseases have underscored the importance of always making sure that you are protected from germs.

Customers will also appreciate the opportunity to use an antibacterial wipe to wipe their hands rather than having to go to the bathroom to wash them. This makes for good customer service and can help to improve the gym experience.

Defining Wind Generated Electrical Power and Discussing Pros and Cons of the Technology

Introduction

Wind generated electrical power exists through harnessing wind-power energy with turbines. To fully understand wind generated electrical power, one must understand how wind powered electricity is made; resources needed to utilize wind power; types and sizes of wind turbines; building a wind turbine; potential positive and negative impacts of the technology; where wind powered electricity can be effectively generated; and, offsetting the costs of wind powered electrical technology.

How Wind Powered Electricity is Made

The technology of wind generated electrical power functions by creating electricity through the use of various styles of wind turbines. Initially, one might ask, “So how do wind turbines make electricity?” Simply said, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.

Resources Needed to Utilize Wind Power

The primary resource of Wind powered technology is, of course, wind. Wind is very abundant in many parts of the United States and other parts of the world. Wind resources are branded by wind-power density classes, ranging from class 1 (the lowest) to class 7 (the highest). Good wind resources (e.g., class 3 and above, which have an average annual wind speed of at least 13 miles per hour) are found in many areas. Wind speed is a critical of wind resources, because the energy in wind is proportionate to the cube of the wind speed. In other words, a stronger wind means more power.

Wind resource development requires land and may compete with other uses of that land, and those alternative uses may be more highly valued than electricity generation. However, wind turbines can be positioned on land that is also used for grazing or even farming. Wherever a wind farm is to be built, roads are cut to make way for shipping parts. At each wind turbine location, the land is graded and the pad area is leveled. Wind energy also requires the building of wind turbines.

Types and Sizes of Wind Turbines

Modern wind turbines fall into two basic groups: the horizontal-axis variety and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor. Horizontal-axis wind turbines typically either have two or three blades. These three-bladed wind turbines are operated “upwind,” with the blades facing into the wind. Darrieus models, or vertical-axis wind turbines, have two vertically oriented blades revolving around a vertical shaft.

In addition to different types, there are many different sizes of wind turbines. Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger turbines are grouped together into wind farms, which provide bulk power to an electrical grid. Single small turbines, below 100 kilowatts, are used for homes, telecommunications, or water pumping.

Small turbines are sometimes used in connection with diesel generators, batteries, and photovoltaic systems. These systems are called hybrid wind systems and are typically used in remote, off-grid locations, where a connection to the utility grid is not available.

Building a Wind Turbine

The first step in building a wind turbine is setting up the tower where the fiberglass nacelle is installed. The nacelle is a strong, hollow casing that contains the inner workings of the wind turbine. Usually made of fiberglass, the nacelle contains the main drive shaft and the gearbox. Its inner workings also contain blade pitch and yaw controls. The nacelle is assembled and attached onto a base frame at a factory.

The most diverse use of materials and the most experimentation with new materials occur with the blades. Although the most dominant material used for the blades in commercial wind turbines is fiberglass with a hollow core, other materials in use include lightweight woods and aluminum. Wooden blades are solid, but most blades consist of a skin surrounding a core that is either hollow or filled with a lightweight substance such as plastic foam or honeycomb, or balsa wood. Wind turbines also include a utility box, which converts the wind energy into electricity and which is located at the base of the tower. The generator and electronic controls are standard equipment whose main components are steel and copper. Various cables connect the utility box to the nacelle, while others connect the whole turbine to nearby turbines and to a transformer.

Potential Positive and Negative Effects of Wind Powered Electricity

There are a variety of potential positive and negative impacts of wind powered technology.

Potential positive impacts include:

• Wind energy is friendly to the surrounding environment, as no fossil fuels are burnt to generate electricity from wind energy.

• Wind turbines take up less space than the average power station. Windmills only have to occupy a few square meters for the base; this allows the land around the turbine to be used for many purposes, for example agriculture.

• Newer technologies are making the extraction of wind energy much more efficient. The wind is free, and we are able to cash in on this free source of energy.

• Wind turbines are a great resource to generate energy in remote locations, such as mountain communities and remote countryside.

• Wind turbines can be a range of different sizes in order to support varying population levels.

• When combined with solar electricity, this energy source is great for developed and developing countries to provide a steady, reliable supply of electricity.

Potential negative impacts include:

• Wind turbines generally produce less electricity than the average fossil fuelled power station, requiring multiple wind turbines to be built.

• Wind turbine construction can be very expensive and costly.

• Wind turbines can have a negative impact to surrounding wildlife during the build process.

• The noise pollution from commercial wind turbines is sometimes similar to a small jet engine.

• Protests and/or petitions usually confront any proposed wind farm development. People feel the countryside should be left intact for everyone to enjoy its beauty.

Where Wind Powered Electricity Can be Effectively Generated

Places in the world where wind blows strong and often, people and businesses can harness the wind as an option to use in the generation of electricity. Globally, these places include much of North America, southern South America, Greenland, most of Europe, Northern Africa, eastern Asia, most of Australia, and anywhere there are mountains or large hills. The top 5 countries producing electrical wind power in 2007 were: Germany, United States, Spain, India and China, respectively.

Considerable wind speeds also occur across oceans and large water bodies. Since most of the world’s population lives near oceans, wind farms with strong offshore and onshore breezes could produce an abundant amount of electricity. On land in the USA, the major wind corridor is the Great Plains which includes the states of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas. The wind corridor also extends into the states west to the great mountains west, including eastern Montana, Wyoming, Colorado, and New Mexico. There are also considerable wind resources in eastern and southern Minnesota and the entire state of Iowa, diminishing south through Missouri and east through southern Wisconsin and northern Illinois, Indiana and Ohio. Parts of New York and the New England states also have considerable wind.

The Department of Energy (DOE) estimates that wind power could supply the US with 100% of its electricity, just from the Great Plains wind corridor or from offshore wind farms alone. According to the “Pickens Plan,” a $10 billion wind farm with 2500 generators can supply enough energy for 1.3 million homes, and for $1 trillion the Great Plains wind corridor could supply 20% of America’s electricity. That would be about 250,000 generators to supply 130 million homes.

In a report published by the U.S. Department of Energy, “20% Wind Energy by 2030: Increasing Wind Energy’s Contribution to U.S. Electricity Supply,” that report concluded that:

• Reaching 20% wind energy will require enhanced   transmission  infrastructure, streamlined siting and permitting regimes, improved reliability and operability of wind systems, and increased U.S. wind manufacturing capacity.

• Achieving 20% wind energy will require the number of turbine installations to increase from approximately 2000 per year in 2006 to almost 7000 per year in 2017.

• Integrating 20% wind energy into the grid can be done reliably for less than 0.5 cents per kWh.

• Achieving 20% wind energy is not limited by the availability of raw materials.

• Addressing  transmission  challenges such as siting and cost allocation of new  transmission  lines to access the nation’s best wind resources will be required to achieve 20% wind energy.

Offsetting the Costs of Wind Powered Electrical Technology

Although wind generated electrical power seems to be an unlimited resource, and, the best wind sites appear to be competitive with market electricity prices in most U.S. regions, several factors exist that make it a less appealing source of alternative energy in terms of economic cost. First off, wind is not uniformly priced resource. Its costs vary widely depending on project scale, wind speed, region, and other factors. Second, the benchmark for comparison with wind to other fuels varies regionally. Third, extra revenue is required to make a project viable, sunk costs are considerable.

To offset the factors that make wind powered electricity a less appealing source of alternative energy and promote its continued growth, wind energy in many areas receives some financial or other support to encourage development. Wind energy benefits from subsidies either to increase its attractiveness or to compensate for subsidies received by other forms of production, such as coal and nuclear, which have significant negative impacts. In the United States, wind power receives a tax credit for each Kilowatt hour produced; that was 1.9 cents per Kilowatt hour in 2006. The tax the credit has a yearly inflationary adjustment. Many American states also provide incentives, such as exemption from property tax, mandated purchases, and additional markets for “green credits.” The Energy Improvement and Extension Act of 2008 contain extensions of credits for wind, including micro-turbines.

Secondary market forces also provide incentives for businesses to use wind-generated power, even if there is a premium price for the electricity, socially responsible manufacturers pay utility companies a premium that goes to subsidize and build new wind power groundwork. Companies use wind-generated power, and in return they can claim that they are making a “green” effort.

Undoubtedly, further tax credits, subsidies and incentives will also be needed to achieve the goal of 20% Wind Energy by 2030. Today, wind power approximately accounts for about 2% of the electricity generated in the United States.

Summary

The technology of wind generated electrical power functions by creating electricity through the use of various styles of wind turbines is a very viable alternative energy. Although wind generated electrical power does have some negative impacts, this author feels that in terms of long-term cost and benefit compared with other types of energy, such as the burning of fossil fuels, using a renewable resource such as wind generated electrical power economically, environmentally, and socially is making more and more sense.

The “Worthy” Poor VS The “Unworthy” Poor

In American Society, we have divided the poor into two classes, the “worthy” poor and the “unworthy” poor. The “worthy” poor are those we feel are worth being on state/federal aid and do not complain about assisting. The “unworthy” poor are those are receive aid as well but for some reason society feels they could take care of themselves and not depend on the aid.

Society feels that those in the “unworthy” class are capable of providing for themselves financially. The reason being that most of the people who fall into this class are younger then the people who fall into the “worthy” class. Many who fall into the “worthy class” are the elderly who are beyond working age, and find it hard to support their selves without some form of a fixed income.

Although the majority of the “worthy” class is made up of the elderly, there are certain situations where the “worthy” class also includes some of a younger generation. Many of those come from the deeply impoverished corners of the United States Society. Many don’t have a chance of surviving and living a better life then they are being given unless the someone, whether it be the government or a small organization, step up and find some way to show them the way to improve themselves.

There are a few such organizations and federal programs in place already, but there are not nearly enough to tackle the large need that we have for the issue. Many people feel that even though they fall into the “worthy” category, they are still not worth wasting time, resources, and money on to educate towards a better life. Many look down on those who need aid regardless of the situation and feel the same about them. They think that they are children, and as they grow they will learn and they will make something better of themselves. Unfortunately, this is not true. As they grow up in a poverished lifestyle they will learn from what they are surrounded with. They will grow up and realize it isn’t so bad to be where they are, because they have not had anyone show them that there is a different way in life.

As American’s, we are a large extended family. Everyone is supposed to look out for their family and protect them. I do not know why no one is protecting the children of these “unworthy” groups and showing them the way to better themselves and enrich their lives. It is going to take more then giving their family a few hundred dollars a month in food stamps and other aid to teach these children how to succeed in life. It is going to take educating them. Not only do these children need to be shown the way, but their parents/parent as well need to be educated on how to enrich not only their lives but their children’s lives as well. It is a two step process, and it is time as a society we step up and start making it a reality instead of a vision. With a little hard work I honestly believe that poverty in the US could be helped dramatically by just a few nice neighbors holding out their hands and showing that they are willing to assist.

IPv4 Vs IPv6 (Advantages and Disadvantages)

We can see the rapid growth of internet users in last few years and this increase also create challenges for internet management groups, stake holders and service providers. Day by day infrastructure of internet is expanding and we can even enjoy the service of internet in villages and remote areas. Increased of usage also increase online devices. In start internet protocol addressing (a specific IP addressing for each online entity) was designed on 32 bit and this scheme IP version called IPv4.IPv4 addressing is like 203.128.076.001. decimal is used to make the IPv4 addresses more palatable for humans and a 32-bit address becomes 4 decimal numbers separated by the period (.) character. If we calculate these decimal values and we can get the total number of devices can be participate on this protocol (256x256x256x256) = allows for 4,294,967,296 addresses. It is about 4 billion of addresses and in early days of internet no one can think, 4 billion slot will be full. here we shall discus some disadvantages of IPv4 as we have seen addressing capability problem and after that we shall go through the solution which will replace IPv4 and addressing structure of the new addressing scheme. we shall go through some disadvantages of IPv4 and new features of IPv6.

Rapid Growth of the Internet and the Exhaustion of the IPv4 Addressing

IPv4 allows for 4,294,967,296 addresses which is about 4 billion and IP allocation limits the public IP addresses to a few hundred million. Cause of this limitation companies using NAT (Network Address Translator) to map single public IP to multiple private IP addresses.

IPv4 Security at IP Level

When we communicate at public medium we need to encrypt data to maintain security and privacy. After a passage of time we have now security for IPv4 packets. This security knows as internet protocol security or IPSec but this is an optional for IPv4.

Internet Backbone Maintaining Large Routing Tables

In IPv4 network IDs allocation is very critical and currently more than 87000 routes in the routing tables of internet backbone routers today. The routing infrastructure is based on flat and hierarchical routing.

Quality of Service Concern in IPv4

Now a days internet users are not only limited with browsing and searching data. Current users are well aware of text and voice and video chat and video conferences and online video libraries. This kind of communication need real time data transfer for quality of service. Normally for these kind of services we use UDP (User Data-gram Protocol) or TCP (Transmission Control Protocol).IPv4 TOS field has limited functionality and, over time, has been redefined and locally interpreted. Additionally, payload identification that uses a TCP or UDP port is not possible when the IPv4 packet payload is encrypted.

IPv6

As we can see we have some basic problems in practice of IPv4 now we will check some new features of IPv6. here I like to describe the some of basic features of IPv6. Deployment of IPv6 is a big challenge for internet management groups, stake holders and service providers. It is difficult but not impossible. We can see benefits of IPv6 here. Biggest upgrade jump from IPv4 32 bit to IPv6 128 bit.

IPv6 Header Format

New header is designed to minimize header overhead. by moving both nonessential and optional fields to extension headers that are placed after the IPv6 header. IPv6 header is more efficiently processed at intermediate routers and that generates efficiency. IPv6 is 4 time larger than IPv4 and its header size is twice than older version.

IPv6 Large Addressing Space

In IPv6 source and destination addresses is based on 128 bit. 128 bit addressing can produce over 3.4 x 1038 possible combinations. Currently we can say this is enough but who know about future may be it also face same problem like IPv4 after some decades. 128 bit addressing allow us multiple levels of sub-netting and address allocation. So we can say that we have plenty of address for use in future.

Addressing and Routing Infrastructure Efficiency in IPv6

IPv6 designed to create an efficient, hierarchical, and summarize able routing infrastructure that is based on the common occurrence of multiple levels of Internet Service Providers. It reduce the size of routing table of backbone routers. Which is can cause of efficient internet experience.

Security features is now built-in

IPv6 has been design to support IPsec (AH and ESP header support required) also support mobility version Mobile IPv6. IPSec based on two types of extension headers and a protocol to negotiate security settings. The Authentication header (AH) provides data integrity, data authentication, and replay protection for the entire IPv6 packet. It is better form developers who built-in security features in development of IPv6 rather we bolt on later.

Quality of Service (QoS) of IPv6

As we have already seen about the UDP and TCP protocols for streaming and other multimedia services on internet. Cause the usage of these services are increasing day by day IPv6 have a flow level field in its header which make better and special handling for packets from source to destination. Data traffic is identified in the IPv6 header, support for QoS can be achieved even when the packet payload is encrypted with IPSec and ESP.
