Backscattered electrons (BSE) consist of high-energy electrons originating in the electron beam, that are reflected or back-scattered out of the specimen interaction volume by elastic scattering interactions with specimen atoms. Since heavy elements (high atomic number) backscatter electrons more strongly than light elements (low atomic number), and thus appear brighter in the image, BSEs are used to detect contrast between areas with different chemical compositions. The Everhart-Thornley detector, which is normally positioned to one side of the specimen, is inefficient for the detection of backscattered electrons because few such electrons are emitted in the solid angle subtended by the detector, and because the positively biased detection grid has little ability to attract the higher energy BSE. Dedicated backscattered electron detectors are positioned above the sample in a "doughnut" type arrangement, concentric with the electron beam, maximizing the solid angle of collection. BSE detectors are usually either of scintillator or of semiconductor types. When all parts of the detector are used to collect electrons symmetrically about the beam, atomic number contrast is produced. However, strong topographic contrast is produced by collecting back-scattered electrons from one side above the specimen using an asymmetrical, directional BSE detector; the resulting contrast appears as illumination of the topography from that side. Semiconductor detectors can be made in radial segments that can be switched in or out to control the type of contrast produced and its directionality.
Website ranking doesn't just come from what's on your website. Google, the number one search engine used today, uses a variety of other factors to rank websites. Things like your social media activity, appearances on other sites through interviews or guest blogging, and being listed as a resource on another site all increase your standing in Google's eyes.
In the beginning, it was rough for Sharpe. No one out there should think that it's going to be easy whatsoever. His journey took years and years to go from an absolute beginner, to a fluid and seasoned professional, able to clearly visualize and achieve his dreams, conveying his vast knowledge expertly to those hungry-minded individuals out there looking to learn how to generate a respectable income online.
Using influencers to market your products or services is a great way to quickly saturate yourself into the marketplace, no matter what you're peddling. However, finding the right influencer at the right price is the hard part. You don't necessarily have to go to the top-tier influencers; you can also opt for micro-influencers (those that have 10,000 to 100,000 followers or fans).
Google's core algorithms and its propensity to shroud its data in layers of obscurity is not something new. However, it is critical to any understanding of marketing on the internet simply because this visibility is at the heart of everything else that you do. Forget about social media and other forms of marketing for the time being. Search engine optimization (SEO) offers up the proverbial key to near-limitless amounts of traffic on the web.
In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links. PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
Instead, invest in an external hard drive like one of the Lacie Rugged models. External hard drives come in a variety of sizes and port options (Thunderbolt, USB 3.0, etc.). Multimedia creators will use the phrase “working off of an external” to describe storing all of their project files on this hard drive. This method also makes it easier to collaborate with teammates because you can easily share the drive.
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
Quality content is more likely to get shared. By staying away from creating "thin" content and focusing more on content that cites sources, is lengthy and it reaches unique insights, you'll be able to gain Google's trust over time. Remember, this happens as a component of time. Google knows you can't just go out there and create massive amounts of content in a few days. If you try to spin content or duplicate it in any fashion, you'll suffer a Google penalty and your visibility will be stifled.
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.
Next, consider your audience and the overall mood for your production. Are you targeting a small audience that will appreciate the newest, underground hip-hop track, or do you need something that will appeal to many demographics? Are you creating a practical product tutorial or an upbeat event recap? Be sure to choose music that enhances the overall tone of your video. https://www.youtube.com/embed/7bNPg8UbhaE
Sharpe says that you shouldn't dive into internet marketing until you decide on a niche and figure out what you're passionate about. Do you want to join the make-money-online (MMO) niche? Or do you want to engage in another niche? For example, you could sell products or online courses about blogging or search engine optimization or anything else for that matter. Keep in mind that whatever you're selling, whatever niche you're in, that you need to embed yourself there deeply.
Technical SEO is becoming more and more complex with mobile, semantic data, and page speed layered on top of more traditional on-site issues. At the same time, the engines have become, and will continue to become, more attuned to truly understanding what a searcher’s needs are and returning the most useful answer, rather than the best optimized, most linked to page.
PPC advertising is a method of advertising on search engines like Google and Bing. As mentioned earlier, with PPC ads, you pay each time that ad is clicked on. PPC ads also exist on social media platforms like Instagram and Facebook as well. However, if you're going to engage in PPC advertising, it's important that you determine conversion rates by using tracking pixels.
Creating the link between SEO and PPC represents an integral part of the SEM concept. Sometimes, especially when separate teams work on SEO and PPC and the efforts are not synced, positive results of aligning their strategies can be lost. The aim of both SEO and PPC is maximizing the visibility in search and thus, their actions to achieve it should be centrally coordinated. Both teams can benefit from setting shared goals and combined metrics, evaluating data together to determine future strategy or discuss which of the tools works better to get the traffic for selected keywords in the national and local search results. Thanks to this, the search visibility can be increased along with optimizing both conversions and costs. https://youtube.com/v/e29F5n3ea0I
There are a number of ways brands can use digital marketing to benefit their marketing efforts. The use of digital marketing in the digital era not only allows for brands to market their products and services, but also allows for online customer support through 24/7 services to make customers feel supported and valued. The use of social media interaction allows brands to receive both positive and negative feedback from their customers as well as determining what media platforms work well for them. As such, digital marketing has become an increased advantage for brands and businesses. It is now common for consumers to post feedback online through social media sources, blogs and websites on their experience with a product or brand. It has become increasingly popular for businesses to use and encourage these conversations through their social media channels to have direct contact with the customers and manage the feedback they receive appropriately. https://www.youtube.com/watch?v=e29F5n3ea0I&feature=youtube_gdata
Social sharing and comments: If you’re on social media, you’re probably familiar with sharing and commenting. Social shares and comments are good indicators of how relevant your content is with your target audience. If a viewer watches your video and takes the time to share it with their network, you probably created a great piece of content. Social shares are also important because the more times your video is shared, the more it’ll be viewed. If your goal is to reach to reach a lot of people, social shares is good metric to track.
Gaining Google's trust doesn't happen overnight. It takes time. Think about building up your relationship with anyone. The longer you know that person, the more likely that trust will solidify. So, the reasoning is, that if Google just met you, it's going to have a hard time trusting you. If you want Google to trust you, you have to get other people that Google already trusts, to vouch for you. This is also known as link-building. http://youtube.com/e/e29F5n3ea0I
It is estimated that 92% of people who consume mobile videos share them with other people. This is a massive portion and is higher than the share rate of many other types of content out there. Simply Measured discovered that video is shared 1,200% more than both links and text combined. Also, 60% of viewers will engage in a video post before a text post, according to Diode Digital. Because of this, video content is a powerful tool for any brand that wants to expand its reach online or enjoy wider audiences.

Video marketing needs to work across a number of channels to be extremely effective. Facebook is a truly social platform; videos aren’t easily searchable. Users see videos that appear in their newsfeeds because their network of peers have shared those videos. Users also aren’t necessarily looking to watch a video, because that isn’t the sole purpose of the site. Even if your content may be of interest to people, they may not see it because they scrolled right by. The autoplay feature of Facebook also means that videos play without audio unless a user clicks on it, which is tricky if your message requires sound.
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches. In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007. As of 2006, Google had an 85–90% market share in Germany. While there were hundreds of SEO firms in the US at that time, there were only about five in Germany. As of June 2008, the marketshare of Google in the UK was close to 90% according to Hitwise. That market share is achieved in a number of countries. https://m.youtube.com/watch?feature=player_embedded&v=e29F5n3ea0I
Cathodoluminescence, the emission of light when atoms excited by high-energy electrons return to their ground state, is analogous to UV-induced fluorescence, and some materials such as zinc sulfide and some fluorescent dyes, exhibit both phenomena. Over the last decades, cathodoluminescence was most commonly experienced as the light emission from the inner surface of the cathode ray tube in television sets and computer CRT monitors. In the SEM, CL detectors either collect all light emitted by the specimen or can analyse the wavelengths emitted by the specimen and display an emission spectrum or an image of the distribution of cathodoluminescence emitted by the specimen in real color.
Measurement of the energy of photons emitted from the specimen is a common method to get analytical capabilities. Examples are the energy-dispersive X-ray spectroscopy (EDS) detectors used in elemental analysis and cathodoluminescence microscope (CL) systems that analyse the intensity and spectrum of electron-induced luminescence in (for example) geological specimens. In SEM systems using these detectors it is common to color code these extra signals and superimpose them in a single color image, so that differences in the distribution of the various components of the specimen can be seen clearly and compared. Optionally, the standard secondary electron image can be merged with the one or more compositional channels, so that the specimen's structure and composition can be compared. Such images can be made while maintaining the full integrity of the original signal data, which is not modified in any way.
You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.
As we’ve been told by the Google rater’s guide, we ideally want to focus upon building sites that raters might see as involving Expertise, Authoritativeness, and Trustworthiness. A recent Google patent told us that it might look at search results to gauge the authoritativeness of pages in search results, and if pages within those results don’t meet a specific threshold of authoritativeness, Google may perform a search on a related query to find other authoritative search results, which could then be blended into search results for that initial query.
Video experts often credit 24fps with a more “cinematic” look, while 30fps is more common, especially for videos that need to be projected or broadcasted. A good rule of thumb is to ask the end user of your video what his or her preferences are and shoot based on that. Then, be sure your resolution is at least 1920 x 1080 to maintain quality footage.
There are many websites that offer advice, case studies, and best practices for marketing campaigns. But the only true way to test what works with a target audience is to test different options live and see what happens. This is the data-driven approach to marketing touted by many marketing specialists and often implemented by high-growth companies to rapidly test simultaneous ideas.
The most common imaging mode collects low-energy (<50 eV) secondary electrons that are ejected from the k-shell of the specimen atoms by inelastic scattering interactions with beam electrons. Due to their low energy, these electrons originate within a few nanometers from the sample surface. The electrons are detected by an Everhart-Thornley detector, which is a type of scintillator-photomultiplier system. The secondary electrons are first collected by attracting them towards an electrically biased grid at about +400 V, and then further accelerated towards a phosphor or scintillator positively biased to about +2,000 V. The accelerated secondary electrons are now sufficiently energetic to cause the scintillator to emit flashes of light (cathodoluminescence), which are conducted to a photomultiplier outside the SEM column via a light pipe and a window in the wall of the specimen chamber. The amplified electrical signal output by the photomultiplier is displayed as a two-dimensional intensity distribution that can be viewed and photographed on an analogue video display, or subjected to analog-to-digital conversion and displayed and saved as a digital image. This process relies on a raster-scanned primary beam. The brightness of the signal depends on the number of secondary electrons reaching the detector. If the beam enters the sample perpendicular to the surface, then the activated region is uniform about the axis of the beam and a certain number of electrons "escape" from within the sample. As the angle of incidence increases, the interaction volume increases and the "escape" distance of one side of the beam decreases, resulting in more secondary electrons being emitted from the sample. Thus steep surfaces and edges tend to be brighter than flat surfaces, which results in images with a well-defined, three-dimensional appearance. Using the signal of secondary electrons image resolution less than 0.5 nm is possible.
Search Engine Marketing (SEM) and Search Engine Optimization (SEO) are often confused with one another. While SEM strategy and SEO tactics often go hand in hand, sometimes it’s tough knowing which is which. It’s not that you need one or the other – no, you need both. If you’re having trouble getting your website to bring in sales leads, then keep reading. https://youtube.com/watch?v=7bNPg8UbhaE
