Why use less Iframe

blogger

The iframes provides a simple way to embed the content of a website to another site. But we need to be careful of using the iframe. iframe created scripts and css DOM elements created by 1-2 orders of magnitude slower than the other.

Use iframe page normally does not contain too many iframe, to create a DOM node takes time so they do not account for a large proportion. But it will bring some of the other issues: onload event and connection pooling (connection pool).

The Iframes blocking page load

Timely trigger window onload event is very important. onload event trigger the browser “busy” indicator stops, telling the user that the page has been loaded. When the onload event to load delay, it gives the user the feeling is that this web page is very slow.

window onload event to trigger all iframe loaded (contain elements inside). Safari and Chrome, set dynamically through JavaScript the iframe SRC avoid this blocking situation.

The only connection pool

The browser can only open a small number of connections to the web server. The old browser contains in Internet Explorer 6 & 7 and Firefox 2, only a domain name (hostname) open at the same time two connections. Increase in the number of restrictions in the new version of the browser. Safari 3 + and Opera 9 + for a domain name at the same time to open four connections, Chrome 1 +, IE 8, and Firefox 3 can be open at the same time six.

Some people may want to iframe will have its own separate connection pool, but not like this. The vast majority of browser, the main page and the iframe shared these connections. This means that when the iframe load resources may run out of all available connections, thereby blocking the loading of the main page resource. If the iframe content more than the contents of the home page, which of course is very good. But the content is usually the case, iframe was not the contents of the home page is important. Then iframe ran out of available connections is not worth. One solution is the important element of the main page is loaded, and then dynamically set the iframe SRC.

The top 10 U.S. sites use iframe. In most cases, they use it to load ad. This is understandable, also a logical solution, a simple way to load the ad service. But keep in mind, the iframe will give you the page performance impact. Whenever possible, do not use the iframe. When does require cautious use them.

The Samsung Galaxy Range Provide Innovative Technology

blogger

The mobile phone industry has taken the entire world by a storm and seems to grow in size every passing day. With such cut throat competition at its end, every brand is steeped in trying to identify its strengths and simultaneously provide innovative technology to boost up their sales.

The Samsung Galaxy Range was launched almost a year ago and has been diligently added with the latest handsets to keep up its own in the face of intense competition. The range has grown to such numbers that even dedicated Samsung fans do not know which to choose. So let us consider the salient handsets comprising this line and compare and contrast them for better understanding.

The 17500 Galaxy was Samsungs first Android and the first to be launched under the galaxy name. It features 5MP camera with LED flash, GPS, Wi-Fi, 3G and 3.2 Amoled screen. The phone was a great newcomer in the ambitious Android phone market; it still holds its ground quite well. Next up is the second Android phone by Samsung, the I5700 Galaxy Spica. It has 3.2 MP camera, GPS, Wi-Fi, 3G, 3.2 Amoled touch screen and a more equipped Bluetooth than the 17500 Galaxy phone. The third phone is the I5800 Galaxy Apollo which comes with a roughly the same features as the Spica but with the added feature of v2.1 Android Operating System and TouchWiz 2.0. It is also popularly referred to as the Galaxy 3. The I5500 Galaxy 5 was launched at 2010s CommunicAsia trade show along with the Galaxy Apollo but it is lower in its estimations when compared by the latter. It has 2 MP camera, GPS, Wi-Fi and its Android v2.1 with TouchWiz 3.0 is over the top. The I9000 Galaxy S takes the galaxy experience to a whole new level. This is the flagship of the range and with its massive spec sheet and massive screen offers it the massive appeal it rightly deserves. It salient features include 4 AMOLED touch screen with multi-touch and Swype keyboard, Wi-Fi, 3G, HSDPA and HSUPA, GPS, Digital Compass, 5 MP Camera, 8/16 GB Alternative Version and Bluetooth 3.0. All this is topped off with 1 GHz A8 processor, Android v2.1 and TouchWiz 3.0, which makes it one irresistible phone. Samsung Galaxy Ace S5830 another Android Phone with 3.5″ touch screen, TouchWiz v3.0 UI, the social hub app, Think Free Office and 32GB expandable memory. A downright stylish phone of this category is the S5570 Galaxy Pop which showcases a 3.14″ touch screen, Android 2.2 operating system, 3MP camera, A-GPS, Quick Office document viewer, Android music & video player, and a 32GB expandable memory. The I8520 Galaxy Beam provides a healthy but not particularly different alternative to the I9000 Galaxy S. In addition the Samsung Galaxy Tab, The Galaxy S2 and the Galaxy S Pro have added new possibilities to the already multidimensional range.

The Samsung Galaxy Price is quiet nominal when compared to its competitive handsets from rival brands which makes all its features all the more attractive.

New IVF technique IMSI at Morpheus ART Fertility Centers

blogger

Male fertility is a real problem and there are indications based on reports from fertility treatment registers in several countries that this is increasing. There are many possible reasons for this increase and the most plausible cause could be the increasing exposure to environment factors that are an outcome of unregulated industrialization as well as lifestyle choices. While we are now constantly warned of the effects of the constant plundering of the environment with visuals of floods and crashing icebergs, we are often oblivious of the reproductive effects of environmental pollution. One example is the evidence that has accumulated over the years into the link between sperm defects and exposure to lead which is an ingredient of common chemicals such as paints that we are exposed to on a daily basis. There are also indications of the toxic effect of agricultural chemicals such as DDT which is widely available and used in India despite a government ban. What is not clear however is the exact mechanism of action of these toxicants on the male reproductive system and modern technology does not allow us to directly link a sperm defect in any individual to a particular substance in the environment. Similarly lifestyle choices and their effects on our health are not surprising. Research does point to the toxic effects of individual lifestyle choices such as tobacco chewing and the indirect effects of decreased physical activity leading to obesity and its possible associated impact on sperm production. But it is sometimes too early to come to a conclusion as the widely publicized and controversial American study on the effects of mobile telephone signals on sperm production in rats was not easily accepted by the wider scientific community.

However research into treatment of this challenging condition has been continuing and has resulted in revolutionary new possibilities. ICSI or intracytoplasmic sperm injection had revolutionized the treatment of male fertility with the ability to use the sperm from men who have had trouble conceiving due to poor quality sperm that had defects in movement, were too few in number or had other problems not detectable by conventional microscopy. In this technique sperm are picked up with a micro-needle and placed within the oocyte. The union of the egg and sperm take place and viable embryos grow out of this union. These embryos are then deposited in the uterus resulting in healthy births in a high percentage of patients. It is reported that thousands of cases have been performed since that path breaking moment in Brussels when sperm were first successfully injected into the center of a human egg. But it has never been entirely clear whether the entire natural sequence of events leading to fertilization is being repeated after ICSI is performed. However the results in terms of live births have been encouraging and as a result there is a definite trend towards increasing use of these techniques. The European society for human reproduction and embryology in its annual reports point to this trend and it is assumed that this increase is both due to an increasing incidence of male fertility as well as increasing confidence in the outcome of this technique.

Another remarkable extension of this technique was when the first successful pregnancies were reported after the use of sperm that were surgically removed from the testes of men who do not have sperm in the semen. Although there were initial concerns about the plausibility of gaining healthy live babies from sperm that are still developing in the testes, the results over the years have given immense confidence to the medical community. As a result thousands of males who could not have imagined having a child have undergone the testicular sperm extraction procedure followed by ICSI and have children of their own.

But sperm pathologies have continued to remain a challenge and ongoing research has yielded few answers to the reason why many men fail to conceive despite all these advanced techniques and seemingly normal partners. There is plenty of evidence to show that genetic defects in the sperm could result in a form of self selection such that these genetically abnormal sperm fail to initiate or complete the sequence of events leading to a healthy embryo. These gene defects are not visible in a normal microscope nor can any sperm that has been exposed to tests to determine the presence of these defects be used for ICSI as these techniques are destructive to the cells. The only test that has shown a relationship to potential is the structural appearance of the sperm cells. These defects can be of numerous types with defects observed in the head, neck or tail of these cells. This simple test of observation is used during the ICSI technique while trying to select out sperm from among the millions of cells. As mentioned above, the most normal looking sperm are selected out using a microscopic size needle at a magnification level 200 times normal. But the power of this selection method is impeded by the magnification level that is achievable by the equipment that is designed for ICSI. This has led to researchers trying to more efficiently perform ICSI by discerning the various structural abnormalities that would not be visible with conventional technology.

A group of researchers in Israel first published their work on the IMSI (Intra-cytoplasmic morphologically selected sperm injection) technique in 2005 and this study was subsequently supported by clinical studies showing its efficacy in groups of patients with extremely severe sperm defects. In this advancement over ICSI, the sperm can be more closely examined reaching magnification levels more than 7000 times. Looking at sperm at this magnification shows defects in sperm head that cannot be seen in conventional microscopes used for ICSI. This has been an exciting new development and numerous births have been reported from extreme cases of male infertility.

Research into male fertility continues with some researchers taking up the challenge of finding methods of treatment in males whose testes do not have capacity to produce any sperm. There have been attempts in other species to create sperm cells from embryo stem cells but modern science is a long way from achieving this successfully with human cells. Until then ICSI and its more advanced version IMSI will be the answer to thousands of couples frequenting fertility clinics for treatment of sperm related problems that are not amenable to medicines or surgery.

The Electric Light Bulb Could Be The Greatest Technology In History

blogger

The history of lighting is fascinating and includes philosophy, art, sciences and religion. Through an extensive timeline, we know that until early man discovered the element of fire quite by accident. He lived in darkness for half of his life. Lightning probably struck a nearby tree and set it on fire, revealing a source of light in addition to the sun and the moon.

But with fire, man could control it and generate heat for warmth and provide energy for cooking. This new source of light gave man a whole new definition of power and control moving him to the top of the food chain.

By bundling sticks together, fire became a torch to transport and light a path to other places. Later, man learned that grease and oil served as fuels for his fire and he could create holders for the fuel. He fashioned an animal horn, a shell, or a rock into a vessel for his fuel and fire. Then, man discovered how a wick added another measure of control, which eventually led to the invention of the candle.

Some people believe the greatest technology in history is the electric light bulb. It is the incandescent light bulb that freed our reliance on daylight. While candles led our way through darker ages, and gaslight was a little better, artificial electric lighting provided another level of control to take us from rudimentary technology to a new source enhancing our quality of life.

Thomas Edison is credited with the invention of the commercial electric light bulb and received a U.S. patent for his design. Edison received over 1,000 patents in his career and holds the record for the most patents granted to one person.

Today, light brightens the Earth from continent to continent as recorded by photography from outer space by satellites and Space Shuttle missions. The light bulb and electricity has afforded nations and humans to prosper and enjoy the fruits of modern technology, as we know it today.

To date, fire and electric lighting has moved our civilization and culture to further heights of luxury that only prosperity can provide. Now it is time to share with those who are less fortunate even in the 21st century. Some companies now donate a percentage of their profits to feed thousands of hungry children located in less fortunate nations. Some people choose to give back. What about you?

LED Bulbs – Technology Led By Care

blogger

Technology led by care – care for the environment – that is the first identity of the LED light bulb. LED or Light Emitting Diode bulbs are solid-state lamps that have semiconductor light emitting diodes (LEDs), organic LEDs, or polymer LEDs. Although the light emitted by one diode is insufficient for domestic or commercial use, multiple diodes put in together normally do the trick pretty well. A single high-power chip emits about 7500 lumens by using a mere 100 watts of power.

Why Use LED Light Bulbs

Notwithstanding the energy efficiency of LED light bulbs, their technology is useful in many more ways. They are mercury-free, which makes them all the more environment-friendly and pro-health. LED bulbs also have an enhanced life of 50 to 100 thousand hours! Their longer life renders them pocket-friendly and cost-effective. LED light bulbs are friendly to more than just your pocket. The simple fact that they do not produce considerable amount of heat during use makes the environment smile in gratitude as well. LEDs convert an amazing 90 percent of the electric energy into light as against a mere 15 percent converted by normal halogen light bulbs.

LED light bulbs are also shock-resistant to a great degree. They can withstand frequent switching on and off better than the normal incandescent and halogen lights. They also weather better in areas of climatic extremes.

Artistically speaking, the LED light bulbs produce light in vibrant colors, which, if used aesthetically, can enhance your interiors as never before.

LED Bulbs: Types

Whether you are a homemaker, an executive, hotelier, or surgeon, there is an LED light bulb for you. There are LED bulbs with different Kelvin ranges for different color temperatures. There are LED bulbs with focus beams of different degrees. The most popular and commercially used LED light bulbs are the GU10 LED bulbs.

The GU10 LED light bulb is so named due to the type of fastening it uses, that is, the standard bayonet mount, acceptable in most Commonwealth nations. GU10 Led bulbs are very popular with businesses that require sharp, crisp, and, of course, cost-effective lighting. Showrooms, offices, shopping stores are a few places that utilize the GU10 bulbs to suit not only their electricity bills, but also the saleability of their stock due to effective lighting.

Add to the enhanced lighting, the additional benefits of the GU10 bulbs like the option of dimmed light, shades of white light, and bulbs designed for several commercial and domestic purposes, make these bulbs highly desirable and efficient. As pure as its color is, the GU10 light bulb is also easy to use and easy to replace when it needs (rarely) replacement.

LED light bulb, especially the GU10 bulb, is a boon to home and office lighting. Not only do they bring your electricity bill right down, they also add that aesthetic appeal to your otherwise drab settings. The LED technology is the result of arduous years spent with the sole motive of reducing the world’s carbon footprint.

LED light bulb technology is the groundbreaking technology in the world of domestic and commercial lighting. GU10 light bulbs are the radical LED bulbs that have enhanced lighting features besides being very cost-effective.
