In secondary electron imaging (SEI), the secondary electrons are emitted from very close to the specimen surface. Consequently, SEI can produce very high-resolution images of a sample surface, revealing details less than 1 nm in size. Back-scattered electrons (BSE) are beam electrons that are reflected from the sample by elastic scattering. They emerge from deeper locations within the specimen and, consequently, the resolution of BSE images is less than SE images. However, BSE are often used in analytical SEM, along with the spectra made from the characteristic X-rays, because the intensity of the BSE signal is strongly related to the atomic number (Z) of the specimen. BSE images can provide information about the distribution, but not the identity, of different elements in the sample. In samples predominantly composed of light elements, such as biological specimens, BSE imaging can image colloidal gold immuno-labels of 5 or 10 nm diameter, which would otherwise be difficult or impossible to detect in secondary electron images.[13] Characteristic X-rays are emitted when the electron beam removes an inner shell electron from the sample, causing a higher-energy electron to fill the shell and release energy. The energy or wavelength of these characteristic X-rays can be measured by Energy-dispersive X-ray spectroscopy or Wavelength-dispersive X-ray spectroscopy and used to identify and measure the abundance of elements in the sample and map their distribution.


In some contexts, the term SEM is used exclusively to mean pay per click advertising,[2] particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting.
Sixty-five percent of business decision-makers visit a marketer’s website after viewing a branded video. It’s clear that quality and relevant video marketing content can dramatically improve your site’s SEO by driving people to your homepage. Additionally, video can enhance your conversion rates: HubSpot reports that 39% of business decision-makers contact a vendor after viewing a branded video.
The dry specimen is usually mounted on a specimen stub using an adhesive such as epoxy resin or electrically conductive double-sided adhesive tape, and sputter-coated with gold or gold/palladium alloy before examination in the microscope. Samples may be sectioned (with a microtome) if information about the organism's internal ultrastructure is to be exposed for imaging.
Digital marketing methods such as search engine optimization (SEO), search engine marketing (SEM), content marketing, influencer marketing, content automation, campaign marketing, data-driven marketing,[6] e-commerce marketing, social media marketing, social media optimization, e-mail direct marketing, display advertising, e–books, and optical disks and games are becoming more common in our advancing technology. In fact, digital marketing now extends to non-Internet channels that provide digital media, such as mobile phones (SMS and MMS), callback, and on-hold mobile ring tones.[7] In essence, this extension to non-Internet channels helps to differentiate digital marketing from online marketing, another catch-all term for the marketing methods mentioned above, which strictly occur online.
The combination of charisma, charm and intellect has helped catapult Sharpe to the top of the heap. In a recent conversation with him, I wanted to learn what it truly took to become an expert digital marketer. And one of the most important takeaways from that phone call was that if he could do it, anyone could do it. For someone who failed so devastatingly very early on in life, to rise from the ashes like a phoenix was no easy feat. http://www.youtube.com/watch?feature=youtu.be&v=7bNPg8UbhaE
What's the authority of your website or webpage, or any other page on the internet for that matter where you're attempting to gain visibility? Authority is an important component of trust, and it relies heavily on quality links coming from websites that Google already trusts. Authority largely relates to the off-page optimization discipline of SEO that occurs away from the webpage as opposed to the on-page optimization that occurs directly on the webpage.

Social Media Marketing - The term 'Digital Marketing' has a number of marketing facets as it supports different channels used in and among these, comes the Social Media. When we use social media channels ( Facebook, Twitter, Pinterest, Instagram, Google+, etc.) to market a product or service, the strategy is called Social Media Marketing. It is a procedure wherein strategies are made and executed to draw in traffic for a website or to gain attention of buyers over the web using different social media platforms.


Inclusion in Google's search results is free and easy; you don't even need to submit your site to Google. Google is a fully automated search engine that uses web crawlers to explore the web constantly, looking for sites to add to our index. In fact, the vast majority of sites listed in our results aren't manually submitted for inclusion, but found and added automatically when we crawl the web. Learn how Google discovers, crawls, and serves web pages.3
There are ten essential types of marketing that can be done online. Some of these can be broken down into organic marketing and others can be categorized as paid marketing. Organic, of course, is the allure of marketing professionals from around the planet. It's free and its unencumbered traffic that simply keeps coming. Paid marketing, on the other hand, is still a very attractive proposition as long as the marketing pays for itself by having the right type of offer that converts.

Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you achieve the shallow depth of field (background out of focus) that people rave about. While they’re primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.

ESEM is especially useful for non-metallic and biological materials because coating with carbon or gold is unnecessary. Uncoated Plastics and Elastomers can be routinely examined, as can uncoated biological samples. Coating can be difficult to reverse, may conceal small features on the surface of the sample and may reduce the value of the results obtained. X-ray analysis is difficult with a coating of a heavy metal, so carbon coatings are routinely used in conventional SEMs, but ESEM makes it possible to perform X-ray microanalysis on uncoated non-conductive specimens; however some specific for ESEM artifacts are introduced in X-ray analysis. ESEM may be the preferred for electron microscopy of unique samples from criminal or civil actions, where forensic analysis may need to be repeated by several different experts.
When they’re considering buying something and want to research their options, there’s a variety of methods used. Some of the top tactics are a search engine, visiting a company or product’s official website, looking at review websites, and watching videos. Video could easily be incorporated into every one of those places, giving your brand a better chance of convincing the consumer.

According to the U.S. Commerce Department, consumers spent $453.46 billion on the web for retail purchases in 2017, a 16.0% increase compared with $390.99 billion in 2016. That’s the highest growth rate since 2011, when online sales grew 17.5% over 2010. Forrester predicts that online sales will account for 17% of all US retail sales by 2022. And digital advertising is also growing strongly; According to Strategy Analytics, in 2017 digital advertising was up 12%, accounting for approximately 38% of overall spending on advertising, or $207.44 billion.
