There are infinite methodologies through we can define the efficiency of websites. There are multitude websites on the World Wide Web and each of these websites is made of a unique programming language. HTML is also a programming language which has been in use for a long time in the designing of a website. The webpages of a website which are being encoded with HTML are more functional and it also helps in the overall designing of a website. On the other hand, CSS is generally known as Cascading Style Sheets. It is widely used to explain the presentation of a document written in a markup language.

The basic difference between HTML and CSS is that HTML is the mainframe scripting language and CSS is just a fragment of HTML which helps the web developers to do crucial activities like editing, formatting, style, colors and lots more. CSS and HTML web designing is the backbone of today’s websites. The programming language plays an important role in how swiftly it will float on various search engines.

If a web developer uses a dumpy and traditional programming language then it will have to endure many obstacles. It often leads to slow loading of webpages and it is the reason why visitors move away from the website. With CSS and HTML web designing an entrepreneur’s website gets loaded on a browser and thus, wins the patience of visitors.

Most of the online retailers expect that their websites to rank higher on various search engines and in this scenario CSS places the content at the top in the page code so that it becomes search engine friendly. CSS and HTML are like the two faces of a coin which work together for designing a website which would be more search engine friendly. Hence the usage of CSS and HTML web designing plays a crucial role in the world of Internet.

These detailed doctor reviews are posted online to help you make those significant decisions about your health. Your little negligence can cause fatal results. It is better to have trust on a reliable and dependable doctor than trying many but unprofessional doctors.

Basic purpose behind posting them and reading them is to obtain sufficient knowledge and information about their qualification and experience. Before consulting and having any medical treatment you must verify their skill, experience, education, consistency and trust among patients and health care field. Today, you can easily get tons of reviews online to make up your mind. It is recommended to always have services of a doctor who is professional, skilled and educated enough to handle any critical situation.

In 2008, the authors published the first edition, The Calcium Lie – What Your Doctor Doesn’t Know Could Kill You. Then in 2013, they updated the information in The Calcium Lie – What Your Doctor Still Doesn’t Know. In this review we will look at the revised edition.

Dr. Robert Thompson, MD who maintains a medical practice in Alaska, at one time did not know what he lays out in this book. He, like most well-meaning health professionals, treated patients according to what he had learned in medical school for many years. Kathleen Barnes, a health journalist and author, lives in North Carolina. Dr. Thompson says that Kathleen helps him communicate in terms that his readers will understand.

This reviewer has administered numerous home school assessments over the years in which the General Information section of the tool she uses includes a question: “What mineral is most necessary to make bones hard?” Many have answered correctly, according to what they have learned and according to the assessment tool, “Calcium.”

Our authors would have us remember that the exam that determines whether a patient has osteoporosis or its precursor, osteopenia is the dexa MINERAL bone scan test. This name should help us remember that bones are made up of many minerals, one of which is calcium. By supplementing calcium alone, we actually harden more than our bones – calcification can occur in arteries, kidneys and other places in our bodies. Dr. Thompson reminds us throughout the book that “Calcium hardens concrete!”

Having gone into medicine with “altruistic” ideas, Dr. Thompson had become disenchanted with his profession, ready to quit. He reconsidered when in 1996 a peer-reviewed directory chose him as one of the “Best Doctors in America.” Encouraged, he decided to continue to make a difference.

Minerally Bankrupt (Chapter 1) – This foundational chapter states that bones consist of at least 12 minerals. “Excess calcium can cause:

• Kidney and gallstones

• Arterial plaque (and heart disease)

• Bone spurs (joints / osteoarthritis)

• Calcium deposits in tissues other than bones

• Brain cell dysfunction, brain shrinkage and dementia.” (p. 9)

• Cataracts

• Cancer

• Diabetes

• Hypothyroidism

• Hypertension (p. 29)

• Obesity (p. 39)

• Migraines (p. 43)

“Too much calcium causes the adrenal glands to be suppressed in order for the kidneys to hold on to the necessary magnesium in an attempt to keep these two minerals in balance.” (p. 19)

Before the invention of refrigeration, our forefathers used sea or rock salt to preserve food. Our natural balance of minerals left with this change. “Because a mineral ‘footprint’ is passed from mother to child, each generation has become progressively more deficient in these essential minerals.” (p. 12)

To add more injury to our systems, when the use of iodine in making bread and canned goods was exchanged with cheaper bromine, we began to see an increase in “thyroid disease and cancer, breast cysts, fibrous changes, cyclic tenderness and cancer, prostrate inflammation and cancer, and ovarian hormonal dysfunction, ovarian cysts, endometriosis and ovarian cancer.” (p. 13)

Table salt destroys health and the best mineral supplement is unrefined rock or sea salt. Dr. Thompson explains that the Hair Tissue Mineral Analysis (HMTA) gives the best possible analysis of the mineral levels and guides the medical practitioner in properly supplementing. He recommends only Trace Minerals, Inc. for doing the test.

Throughout the book, Dr. Thompson gives mini lessons on biochemistry that all doctors study in medical school. Amazingly, most doctors have forgotten their biochemistry and continue to follow the “Calcium Lie,” “The Calcium Myth” (chapter 2), and “The Vitamin Lie” (chapter 7).

Our authors devote chapters to the following health conditions and how they relate to calcium:

• Osteoporosis, Osteoarthritis and Calcium (chapter 3)

• Digestive Dilemmas: Poor Protein Digestion, Sodium Deficiency and Cell Membrane Dysfunction (chapter 4)

• Metabolic Failure How Excess Calcium Causes Weight Gain, Thyroid and Adrenal Malfunctions and Five Types of Hypothyroidism (chapter 5)

• Women’s Issues: Pregnancy, Childbirth and Menopause (chapter 6)

Stress plays a key role in our heath. Thompson and Barnes address this issue and its relationship to Calcium (chapter 8). They emphasize that “stress management must be a regular part of a healthy life style.” (p. 176)

In chapter 9, The Road Back to Health they give their readers the following steps:

1. Drink pure water.

2. Take ionic sea salt – derived supplements.

3. Whole food vitamins.

4. Essential Fatty Acids

5. Eat raw nuts and/or seeds daily.

6. Eat high quality protein.

7. Get essential monosaccharides. (p. 184-195)

The Calcium Lie II closes with chapter 10, “Doctor to Doctor: An Impassioned Plea.” He encourages his readers to copy this chapter and take to their doctors or better yet to purchase a copy of the book for their doctors.

Dr. Thompson and Kathleen Barnes present the facts behind their claims. Reading and following their guidance will improve our health.

Stress affects all students, from graduate level to those in the kindergarten. The term stress refers to the response you have when facing circumstances that force you to act, change or adjust in some way to keep things balanced. It is your body’s way of responding to any kind of demand. It can be caused by both good and bad experiences. In the right dose, stress can be healthy or even enjoyable. However, stress can be very damaging for students when it becomes excessive. It can harm students’ health, happiness, performance, relationships and personal development. This article will deal with management of negative stress.

Causes Of Stress In Students

Causes of stress in school children include; bullies, a mismatch between student and teacher, concerns about not having enough friends, not in the same class as friends, peer pressure, lack of family time, over scheduling of extra-curricular activities, insufficient sleep, poor diet, lack of preparation, noise pollution among others.

As the students progress to a different level the causes of stress often increase. When students go to college or university, they have to contend with leaving their parents and beginning the process of finding their own identity as adults and their place in the world. The main causes of stress here will therefore include; the new university or college environment, payment of fees, the new relationships formed, the competitive circumstances, exams, lack of proper time management techniques, peer and parental pressure.

How Students Can Manage Stress

Students can manage stress using various techniques. The most important of these are;

1. Learning to manage their time wisely. This is done by setting up a study schedule, breaking up studies into smaller chunks. In short, students are advised to formulate, with the help of their teachers and parents, study timetables and adhere to them.
2. The student will also need to have a system of organization for note-taking, keeping track of assignments and other important papers.
3. Creating a good study environment is also a great tool for stress management. Students have different study habits. While some need a completely quiet room free from interruptions, others actually study better listening to quiet music in the background. A student should pick which is best for him or her.
4. Determining the most appropriate learning style: whether the student is a visual, kinesthetic or auditory learner. Tailoring your study practices around your particular learning styles makes success easier to attain and keeps stress at bay.
5. Using relaxation techniques like deep breathing, visualization or imagery, progressive muscle relaxation, meditation and yoga. Additionally, being optimistic will help students become healthier, less stressed and more successful.
6. Learning how to budget money, spend wisely and pay bills on time, if any, is very important for the student’s survival and will lower stress levels.
7. Lastly, students must take care of their bodies and minds by getting proper nutrition, getting some form of physical exercise and getting enough sleep. Seven hours of sleep each night is recommended for optimum body and brain function. Naps, not exceeding one hour, should also be taken when needed.

Following these tips will help you greatly to reduce the stress and it might even help to improve your performance on exams.

This question seems like a dream if the answer is yes. Wouldn’t it be great to just sit down in your massage chair and lose weight? However, life is never so simple. Massage chairs can aid in the process of weight loss. The true path to weight loss includes eating right and ongoing exercise. Massage chairs can assist in weight loss by helping to shed some of your lingering pounds or by taking you on a path to better health.

In order to live healthy, you need a whole some and relaxed body, mind and spirit connection. Massage is used routinely to help induce relaxation of the mind and body. It provides for a time for you to focus on yourself. Getting frequent treatments is important to sustain a healthy body and mind connection.

When we undertake a weight loss program, we normally start by eating better and exercising frequently. We start to see improvement with losing weight and the beginning of the exercise program. However, we then seem to plateau as the body stabilizes and it becomes harder to lose additional weight.

Most of the early weight loss is simply water loss. Our bodies are made up mostly of water. As we change our diet and begin exercising more we start to lose more water weight. Receiving massages during this period helps to release this excess of water in our bodies.

Another important benefit is the movement of the lymph and other fluids in your body. The lymph removes and cleans toxic material out of your cells. Receiving regular massage treatments helps to move this fluid and flush it out of your body. Regular flushing of toxins is important to maintain your body in prime health.

Massage therapy is known to help increase muscle tone. This helps to build muscle and aids in your ability to control or lose weight. If your muscles are strong, then your muscles will burn more calories. This enables you to perform a variety of activities to maintain health.

There is some research to suggest that massage therapy may contribute to the loss of fat. The penetration of massage into the soft tissues is believed to burst the fat capsule. When the fat capsule is burst, it can be more easily absorbed and removed from your body.

Increasing the level of your metabolism is important to lose weight. A higher metabolism helps your body to more easily perform its normal processes. Receiving periodic massage chair treatments helps to increase blood and fluid flow in your body. The blood flow in particular is vital to improving your metabolism.

Regular treatments are believed to influence the excretion of fluids for tissue repair. These treatments stretch the muscles and connective tissue helping to break down scar tissue more quickly. This may speed up recovery from normal training and injuries.

When you begin to work out regularly, you may tend to get soreness and tightness in the muscles. This can occur from a build up of lactic acid. Regular therapy provides a means to help reduce the build up of lactic acid leading to pain reduction.

There are many benefits to receiving frequent massage chair treatments. These types of treatments should be seen as a stable and healthy living. Massage therapy is an important element in your total health program. It is important to take time to relax and to focus on yourself. Massage chairs can assist you in your weight loss goals and healthier living.

To wear and enjoy a beautiful piece of antique and vintage jewelry with a history behind can be a wonderful, exhilarating experience. For many it is a lovingly addicting hobby. The more you collect, the more you want to collect! It's that exciting! But when buying these jewels of yesterday, how can one be certain that what they are buying is truly authentic and not relatively new and / or of it's claimed value? It's always advisable to buy from reputable dealers who guarantee their items plus learning what to look for in a piece. Attend Antique & Collectable Shows, browse Antique Shops and read lots of books to familiarize yourself with period styles and their findings.

When looking at a piece, examine it carefully both front and back. An genuinely old piece will have all the ingredients to confirm its authenticity. Many jewelry styles do tend to overlap so always check the entire piece for clues. Is the piece signed, hallmarked? Surprisingly enough a lot of antique jewelry was marked in the most unusual of places so check along the edges, inside of the bale, the pin stem and even on the back of the pin stem! You'll be amazed at what you could find and where you will find it. Suddenly a piece of jewelry that you thought was newer or made of silver plate or gold plate now may be seen in a different light as genuine antique silver or gold and have a lot of value!

A lot of old jewelry such as Victorian Jewelry was not marked. So now what? A Victorian brooch with a long pin stem extending outward is a good indication that it's early Victorian while a shorter one is of a later date. The "C" clasp is another indication that the piece is old. Remember that there are always exceptions to the rules since the "C" clasp was also used later on in Europe so take every detail into account to come to your full conclusion. Look at the hinge and the clasp of a brooch, bracelet, necklace, etc .. Does it look like a clasp used today or does it seem a bit different to you? Compare new pieces to old pieces. Does the jewelry have a brass spring ring clasp from the 1930s or a shiny gold plate clasp? Are the findings on a piece consistent with the design of that era? Those small differences could answer your questions and drastically influence the value of a piece. The tube hinge was generally used until the 1890s where the safety catch clasp became popular in the Art Deco 1920s period. Over the years the appearance of the safety catch clasp has changed so it's good to recognize the old from the new. Many clasps on old jewelry such as pins broke in time so replacement ones were soldered onto the back. All better Jewelry is soldered at some place but if the piece has raised pads soldered to the back of the Brooch where the clasp is attached then it is a replacement clasp.

Another good clue to dating a piece and determining the value of Antique and Vintage Jewelry is to look at the metal content where there might be some underneath wear, usually in back where it would rub against the clothing. Genuine Gold and Silver, even if it has wear, will not show a base metal underneath since it continues all the way through. Many costume pieces from the nineteenth century and into the Art Deco period were made of gold and / or silver over base metals such as gold over brass, silver over brass, silver over copper, gold over copper, etc. That's one way of knowing the piece is at least 60 years old and more. During the war years of the 1940s there was a shortage of base metals where it affected the jewelry industry so sterling silver was substituted. If you see a marking such as "1/20 12K on Sterling" then 1/5 of the piece is 12K gold and is likely to be from 1942 to 1945. Vintage Bakelite which is a Polymeric Plastic invented by Leo Hendrik Baekeland in 1907, became popular in jewelry design during the hardships of World War II also. There are several tests in determining Authentic Antique and Vintage Bakelite Jewelry using Formula 409, Hot Water, Simichrome Polish and a Q-Tip. Still some Bakelite such as Black Bakelite may not test positive. Since Bakelite is either cast or molded it would not have a seam line anywhere and the workmanship should look hand carved and not be crudely executed as if a stamp was used. On Vintage Bakelite brooches, the clasp would be embedded into the piece.

Fine Jewelry containing Diamonds or Precious Stones such as Rubies, Emeralds and Sapphires are either bezel-set, inset or set with prongs and will always have open-backs for maximum brightness. Air bubbles seen in stones is a clue right off that the piece is glass. Marcasites which were substituted for diamonds as early as the 1700s, regained it's popularity in the 1920s and 1930s. A higher valued marcasite piece would have better workmanship where each marcasite would be set with tiny prongs or beads versus glued in ones and because of this the stones will stay in place longer. This is also true for Rhinestones in Vintage Costume Jewelry where prong set ones are valued higher than glued in ones.

These are just some of the many tips to knowing your Jewelry. It's so helpful to learn what to look for when buying Antique and Vintage Jewelry which also can be as much fun as wearing and collecting it! Knowledge is definitely Jewelry Golden!

Buying a new phone is not an easy affair with so many options that are available in the overcrowded market. It becomes more confusing when you have to choose between a smartphone and a tablet. Read on to find out how you can select a device you actually need and not the one you want!

Size matters

The difference in the screen size of the smartphone and tablet is the first notable and important difference. A Smartphone is supposed to be smaller in size and more compact while a tablet is a much larger option with a bigger screen size. However, the size difference is now blurring as some phones come with a screen size comparable to that of a Tablet.

Playing Games

If you want to play games all day round on your fancy gadget and watch the latest movies or read the interesting books, then the choice is definitely a Tablet.

The larger screen and better video quality will ensure that you have a comfortable experience while performing all these activities on your tablet. Although, all these can be done on a Smartphone too but the small screen size will make it annoying for you to keep scrolling right and left.

Texting

Texting and messaging is a breeze on a Smartphone with its handy design. So, if you are a Whatsapp or Facebook addict and send a lot of emails or updates throughout the day, then a smartphone is definitely a better choice. On the other hand it is not easy to hold a tablet and type text messages like you do in a smartphone.

Click! Click! Click!

Clicking photographs from your Smartphone is a piece of cake and you get better quality photographs with the point and shoot snapper of the Smartphone. Tablets have cameras but the quality and the resolution is not as good as that of a Smartphone. So in the category of photography choosing a smartphone would be a wise choice.

Presentations on the Go

Tablets are perfect for making presentations and planning out your whole business meeting on Skype. The larger keyboard helps in better typing and taking down notes when in a meeting. So Smartphones will not prove to be very accommodating in this aspect.

Net Surfing

Depending upon the nature of your browsing we would give good marks to a smartphone as well as a tablet! Net surfing on the go is more convenient on a smartphone, whereas if most of your usage is at home, a tablet should suit the purpose better.

However, choosing a smartphone or a tablet still remains a tricky choice. Before you opt for one ask this question to yourself. Does it cater to all my needs? Am I just blown away with the design? Now it's up to you and your determinants to choose the best device for yourself.

With big data software companies and cloud providers using up a large amount of data, there has been a substantial increase in the practical application of AI.

Financial institutions have longed used an artificial neural network to detect system changes and abnormal claims while alerting and flagging them for human to investigate.

Many banks are making use of artificial intelligence systems to maintain book-keeping, organize operations, manage properties and invest in stock.

Artificial intelligent defined as a theory and development of computer systems to perform tasks normally associated with humans such as decision-making, visual perception, and speech recognition has been in existence for a long time.

With advancements in computational hardware, big data, and machine learning, artificial intelligence is becoming more powerful and useful every day.

Recent advances in artificial intelligence have ushered in a new era in finance and within a short period of time, big data and machine learning have yielded breakthrough that resulted in improved customer experience and productivity.

Software plays a huge role in this breakthrough and there still remain a lot of challenges to solve. There is a need for software to be designed and optimized to fully take the advantage of the features of the underlying hardware to improve performance. There is also need for libraries, framework and other tools to be streamlined in other to accelerate the development process. Some of these problems have been solved because of the advance in GPU.

Here are a few areas in finance that artificial intelligence is already having an impact:

• Financial service providers and banks are deploying AI to help predict and plan the way customers manage their money and thus making AI an integral part of business development strategy.

• The capability of smart machines to turn data into customer insights and improve services is transforming the digital experience. By utilizing complex algorithms and machine learning, AI can process thousands of structured and unstructured data points and because finance professionals heavily depend on data, this capability can significantly impact how they do their jobs.

• Auditors feel freeing of responsibilities due to automation potential provided by artificial intelligence. They are using AI to automate time-consuming and manual activities, giving them time to focus on more important job. AI can help auditors to review contract and document faster by employing machine learning technology that can find key phrases from documents that take a lot of time to decipher or interpret. Currently, AI can process language in a document and produce relevant results, this has played a crucial role in improving productivity.

• Data-driven management decision at low cost is ushering in a new style of management and in the future, managers will able to question machines instead of human expert. Machines will analyze data and make a recommendation that team leaders will base their decision upon.

• Embedded application in end-user devices and financial institution servers can analyze a large volume of data, providing customized forecasts and financial advice. Applications like this can also help to track progress, develop financial plans and strategies.

• Personalization is a major area where many banks are already experimenting with various ways to match services and products for customers. AI can help customers to simplify money management process and make a recommendation for upgrade by matching algorithms.

In conclusion, financial service providers need to pay attention to AI as the technology continues to evolve and become more mainstream. The way businesses innovate and implement major strategies are shifting, corporate organization needs to embrace AI in other to fully take the advantage the trend.

Not everyone appreciates the important contributions of hospital defense attorneys. Here are a few examples of the many cases where their help could be critical for a medical facility.

Equitable Employment

When a facility grows and takes on a large staff, it's likely that employment issues will arise. Everyone deserves a fair chance at a job, regardless of his or her race, religion, or orientation. Still, some employees will feel that their termination or missed promotion was due to one of these factors. Without hospital defense attorneys on staff, it may not seem worthwhile to confront these allegations directly. With appropriate legal help, it is often possible to resolve these cases favorably and minimize the final expense, even if settlements are necessary.

Resolving Compliance Issues

Litigation is often necessary for compliance related issues in regards to medical care regulations. It is important to comply with all standards that can affect patient care, but still, some conflicts are inevitable in a large enough institution. New staff needs to be trained periodically, and experienced professionals can make mistakes.

Whistleblowers and Fraud

Whistleblowers are an important means of keeping institutions accountable and supplementing the work of inspectors, and yet false claims can be an expensive hassle for large institutions. In an era when the American healthcare system remains under constant scrutiny, it can be difficult for government agencies to dedicate their resources to investigating actual offenders. Rather than remaining at the mercy of disgruntled employees, it is important to take an active stance when it comes to defending against false accusations and fraudulent reports.

Medicare and Medicaid Law

Depending on the demographics served, a significant portion of revenue may come from Medicare and Medicaid payments. Elderly patients with good insurance coverage may still rely on Medicare to cover part of their payments. It can be difficult to keep up with the latest paperwork and expectations of these major government programs. Having a legal team on retainer can be a lifeline when it comes to complicated paperwork. With the nature of state-sponsored medical coverage changing on state and federal levels, guessing about which procedures might be covered will expose a hospital to major financial risks.

Overpayment Recovery

When patients and insurance companies both make payments, sometimes there is a miscommunication or miscalculation resulting in an overpayment to the healthcare provider. It is illegal for the healthcare provider to keep the surplus, and yet identifying and reimbursing overpayments can be a tedious challenge for a busy facility. When secondary payers and other entities are also contributing payments, it can further increase the difficulty. A hospital looking to protect its reputation in the community might be slow to collect significant debts from uninsured patients, but a relatively minor overpayment discrepancy can result in major legal fees and complications.

Hospital defense attorneys are just one part of the network of support staff necessary to maintain a large healthcare facility. Make sure that your facility is keeping its bases covered by keeping a legal team on retainer.

Natural stone tiles are gaining more and more popularity among homeowners just because of the fact that they can provide the right kind of beautification to any house. The great thing about these floorings is that they are highly durable even in the areas with extreme climatic conditions. Generally, when a product gets more popular among the consumers, the manufacturer will become more and more responsible for ensuring that the same quality is maintained for getting continuous customer support. Like this, whenever a product gets popular, similar types of duplicate products getting introduced in the market is unavoidable. So, the purchasers should be careful about the selection of the right product irrespective of whether they are looking for exterior natural stone tile or interior natural stone tiles. Let us get into the details about the three points to be considered during the purchase:

Solidity: This is pretty an easy thing to measure and people can judge the solidity of the product by breaking it. If it is hard to break, the buyer can be satisfied that he has the right natural stone in his hand. Also, he can try to drop a hammer from a good height for testing whether it breaks. In some showrooms, there will be a separate space for conducting this type of tests on the stones. The dealers provide this sort of space just because of the fact that they are highly confident about the quality of the product that they deal with. If it is of the best quality, there will not even be a mark of the hammer. On the other hand, if there is a crack, it might be of cheap quality.

Water absorption: A real stone irrespective of whether it is exterior or interior natural stone tiles, will not take in water even to a slight extent. This is why they are used these days in wet surfaces like bathrooms, swimming pools, Jacuzzis and even other areas, where wetness is highly possible. When an individual is looking to purchase other types of tiles for his bathroom, the water absorption capacity should be checked.

Resistance to weather: Some types of floor tiles are chemically and synthetically designed. But, exterior natural stone tiles have the innate ability to withstand even tough weather conditions. When a homeowner opts for the one with inferior quality, rain, sleet, snow and wind can cause serious damage to his property. On the other hand, greater protection can be obtained when the right natural stone tile is selected for the exterior installation.
