The higher the density of the liquid the higher rise in the reading level of the hydrometer.Īlthough ships are made up of metals whose density is remarkably higher than that of water it is made in such a way that its weight is equal to the weight of the water displaced by it. In a hydrometer the liquid rises vertically by which we can know the density of liquid in its reading. Similarly in order to descend one just simply needs to decrease the heat inside the hot air balloon.Ī hydrometer is an instrument which is used to measure the relative density of liquids. In order to ascend higher one simply needs to increase the heat inside the hot air balloon which results in higher buoyant force acting on the balloon. Besides giving the explanation of What is archimedes principle Explain using an example, a detailed solution. The upward force acting on a hot air ballon is greater than that the surrounding air as the density of hot air is less than that of cold air. defined & explained in the simplest way possible. The displaced volume is directly proportional to the volume of the object and not to the mass of the object. A balloon filled with helium floats in the air as the density of helium is less than that of air. This is true for objects floating in the air as well. This same principle is used in the making of ships. To use Archimedes’ Principle to determine the densities of a solid sample and a liquid sample. If it is reshaped and built in such a way that the displaced water is equal to the weight of the water block then in such case the iron block will float on the surface of the water. To study buoyant force as a function of submersed volume. Archimedes principle and buoyancy Teaching Fluid Mechanics Using Mathcad Ahlam I. When this solid iron is immersed in water then only 18 of its weight of water is displaced and the iron sinks in the water. explained under the umbrella of shear stress which is the force on a unit. Let us take a solid iron block whose density is 7874 kg/m 3 which is almost 8 times more than that of water whose density is 1000kg/m 3. In order for an object to be afloat on the surface of a fluid, its density must be less than that of the fluid. Law of Flotation states that, For a floating object, the weight of the object equals the weight of the liquid displaced by the object.Īs we have already written in the formula section of this blog we know, a body floating on the surface of a fluid, the weight of the object is equal to the weight of the displaced fluid. In simple form, the Archimedes law states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. But this concept can also be used to know why some objects float on the surface of fluids. We already know that Archimedes Principle shows us the upward force exerted on the body which is equal to the weight of the fluid displaced.

While micro influencers have a closer and more engaged network, macro influencers reach a much larger (and often very aspirational) audience. Macro influencers are basically famous people, either celebrities or social media personalities, with more than 100k followers.Īs a result, brands usually approach these macro influencers to feature a product on their social media accounts, and this way the awareness and visibility of the brand increases. 90% of marketers in an Influencer Marketing Hub study chose engagement rates as a measurement of success for their influencer marketing campaigns. So, if engagement rate is what you’re after, then micro influencers are the way to go. Now this is how brands can truly leverage the naturally high engagement rates that micro influencers have as a way to get their brand name and products in front of engaged users. This enables Forever21 to take advantage of a receptive micro-influencer audience and ultimately build brand trust among Kristal’s followers”.Īs a result, she racked up a very good engagement rate of 25.1% out of 130 comments and 3,361 likes. While micro influencers have a smaller reach, their accounts boast high engagement rates, which means their audience keeps up with the content they share.īut, what kind of engagement rates do micro influencers achieve?Īccording to a case study by Mediakix: “Cultivating a loyal audience of nearly 14,000 followers, Kristal engages her followers by replying to comments and showing her appreciation. They deal with your product information directly and gain a deeper understanding of your brand, making their recommendations more credible.They will usually go the extra mile to create high quality content and impress their brand partners.

The default port number assigned to HTTP is TCP port 80. The IP provides support for routing and addressing (via a unique IP address for machines connected to the Internet) while TCP supports multiplexing via 64K ports from port number 0 to 65535. HTTP is an application layer protocol runs over TCP/IP.The process repeats for the next request-response.(client) The client-side program receives the query result and displays on the browser.(server-to-client) The server-side program receives the query parameters, queries the database based on these parameters, and returns the query result to the client-side program.This sends the query parameters to a server-side program. (client-to-server) The user fills up the query criteria inside the form and submits the form.(server-to-client) The HTTP server returns an HTML form (client-side program), which is loaded and rendered in the client's browser.(client-to-server) A user, via a web browser (HTTP client), issues a URL request to an HTTP server to start a webapp.Server-Side Programs: Could be written in Java Servlet/JSP, ASP, PHP, Perl, Python, JavaScript, and others.Client-Side Programs: Could be written in HTML Form, JavaScript, and others.Database: E.g., Open-source MySQL, PostgreSQL, Apache Derby, mSQL, SQLite, OpenOffice's Base Commercial Oracle, IBM DB2, SAP SyBase, Microsoft SQL Server, Microsoft Access and others.HTTP Client (or Web Browser): E.g., Internet Explorer (MSIE), FireFox, Chrome, Safari, and others.HTTP Server: E.g., Apache HTTP Server, Apache Tomcat Server, Microsoft Internet Information Server (IIS), nginx, Google Web Server (GWS), and others.Examples of webapps are google, amazon, facebook and twitter.Ī webapp is typically a 3-tier (or multi-tier) client-server database application run over the Internet as illustrated in the diagram below. import Introduction Web Application (Webapp)Ī web application (or webapp), unlike standalone application, runs over the Internet.

Anything and everything about the Kobo eReader. Keep adding fur to the rest of the drawing, particularly on top of the dog’s head. I’ve used a mechanical pencil 0.5mm and a 6B graphite pencil. Start by making short consistent strokes around the eyes with a preferably darker pencil to indicate the shadowy fur around the eyes. So, pay attention to your subject for those minor but important details. Unlike our previous drawing of the cat which required sketching long fur around some areas. For instance, some have long fur while others like the one we’re working on (Weimeraner Dog) are characterized by short fur. I’ve done the same for the dog’s nostrils – pay attention to the small circles and the deep middle of the nose surface and shade accordingly.ĭogs come in different types and breeds which determine their physical characteristics. Start with the eyes and make sure you nail them as realistically as humanly possible.įor the dark pupils and shadow, I’ve used 8B graphite pencil, followed by 4B, and HB depending on the degree of lightness or darkness on the values scale. Now it’s time to bring them to life by precise shading. Remember, you had done all the hard work of determining where every important detail should go. Adding Details to the Eyes and Nose (for a realistic look) Make sure not to shade the eyes, nose, or any important detail you had sketched earlier.ĥ. I prefer to use the hatching shading technique which works quite well with my style of drawing.Īfter you’re satisfied with your shading, use the cotton earbud to blend in the graphite so that you have as smooth a shade as possible. Use your favorite shading technique to uniformly shade the entire sketch to give it some form. All you need are two things – a 2H or H graphite pencil and a soft cotton earbud. Draw those as accurately as you can.ĭon’t shade just yet but rather sketch where everything should be. Pay extra attention to the pupils, the reflected light, the shadows, the watery pockets, and any other details around the eyes. If well executed, they’ll give your drawing character and subtle emotions. Drawing the Eyes and Other Facial Featuresĭon’t forget we’re not going into details just yet but rather noting where everything should be.įor the same reasons, the eyes are without a doubt the most important part of our drawing. Therefore, make sure to capture every bit of detail beforehand if you can.ģ. The surface is covered with spore-like structures which are often wet. The nasal cavity is divided into two separate chambers and opens into two nostrils or nares. Pay attention to details and you’ll realize that it’s not just shadows but an elaborate ecosystem of small bits and pieces. A dog’s nose is deceptively simple but there’s more than meets the eye. Next, we need to start by accurately outlining our Weimaraner’s nose. Sketch all the important areas including the ear flaps, the muzzle, the neck muscles, and any wrinkles or folds.īy the end of it, you should have the following outline: To do this focus on one box of the grid at a time so that you don’t get overwhelmed. When sketching the dog’s head, start with the general outline. Once you become proficient with time, you can draw freely without those gridlines. If you want to draw to scale and have a realistic drawing, start by using the grids to guide you. Sketching the Dog’s Head, Ears, and Neck Area Here’s the image as well as the link: Alexandru Rotariu via However, for today’s tutorial, you can download my reference photo, and let’s get to work. I’m not a lawyer but I know as much – if you need more information on copyright law consult a qualified attorney. As a reminder, use photos that you own, royalty-free, or get permission from the original owner to avoid infringing on other creators’ copyrighted work. Let’s start with acquiring a well-lit reference photo. That’s why I’m excited to draw this versatile dog while teaching you how to do the same. It is said that when hunting, this dog’s instinctive hunting method is to attack the prey’s genitals to bring it down – an instinct shared with hyenas.Īll said and done this dog breed is adorable. They’re known for courage, speed, and intelligence.īesides, they’re remarkable pointer and hunting dogs. In this tutorial, you will learn how to draw a dog head (Weimaraner to be precise) as realistically as possible with a front view.Īlso known as Grey Ghost, the Weimaraners are sleek, short, or long-coated. They are loyal, loving, and always happy to see their owner. The next morning, the three began working on RSA (from their last names) in earnest. He called Adelman on the phone and told him about the new algorithm. After seder in 1977 ended, Rivest continued to think about the problem at home. During a Passover seder, which tells the story of the Jews' exodus from Egypt, four glasses of wine are consumed. Three MIT faculty members - Ron Rivest, Adi Shamir and Leonard Edelman - had postulated before on how to implement the Diffie-Hellman algorithm, which was subject to man-in-the-middle attacks. Well, you can blame the RSA encryption algorithm on too much Passover wine. You hear about people doodling technical ideas on a cocktail napkin. Others include the Raving Daves (named for then-CEO Dave Duffield) from PeopleSoft, Excite's Where's Julio and Severe Tire Damage, comprising Digital Equipment and Xerox PARC employees. The first officially sponsored band, the Rockumentums, debuted at the Documentum Developer Conference in 2004, where they performed "some of the classics." EMC's band is not the first musical group formed at a tech company. Employees use the 250-meter, 100,000-gallon pool for recreation. Instead it built a pool to be used as a backup water holding tank for fire suppression. The company considered building a water tower, but thought it would be an eyesore. When EMC began planning for its new headquarters building in Hopkinton, Mass., back in the late 1990s, it was required to have 200,000 to 250,000 gallons of reserve water on site for fire protection. Now if only websites realized their ads were so obnoxious that JUST MAYBE less obnoxious ads would result in less ad blocking and more revenue. Technically the app is above all the rest since they’ve managed to implement more than 50,000 policies using a modular system. I’m sure it is a full time job just keeping that up to date so the app cost is perfectly reasonable. Well, this blocker effectively stops that crud with the latest policies. I only wish that some websites that I visit and enjoy had ads that weren’t so utterly obnoxious that they hijack my Safari with a new page to announce “You’ve own a prize! Click OK!” And then I can’t find my way back because swiping back just loads the ad again. This one bucks the trend and goes full throttle ad blocking with great configurability such as easy white listing. Many OTHER ad blockers have fallen into disrepair, not having been updated in ages or at least visibly updated and losing their effectiveness. We are happy that you are satisfied with the way our app works.Īlso, we will take your feedback into account while testing 1Blocker. I turned that off, let Safari process the rules, and reloaded the page. I got a link from my grandma for an article there and when it loaded I assumed none of the blockers were on or maybe I had it whitelisted and I did have it whitelisted. I have never had issues until the last few weeks or so. With all blockers turned on and given permissions, Forbes just runs wild with huge banners and pop ups. Sites like Forbes are not cooperating at al. Regardless, I’m satisfied that things are operating as expected. However, the whitelisting settings remained inside the extension. After removing the toggles inside the app, the blocking resumed as expected. I discovered today that even though I had removed the whitelisting rules inside the safari extension, those rules were being overridden by a whitelisting setting in the app itself. Update: so there seems to be a gap between settings inside the 1Blocker app and the whitelisting section of the extension inside safari. We believe it’s the best all-around package currently available in the App Store. We’ve learned a lot from our customers and improved the app consistently for 5 years to suit all your needs. Your feedback is always very welcome and considered for the next release. Send your feedback at on Twitter or via email. The possibility to see blocked resources on a site.Whitelist synchronization between devices via iCloud.Whitelisting sites right from the Safari extension.The ability to enable one category (for example, Block Trackers only).Your preferences and custom rules are always in sync through iCloud no matter which device you're using.ġBlocker has been featured in TechCrunch, Lifehacker, MacStories, Macworld, and many more. (Available in Premium)ġBlocker is available for iPhone, iPad, and Mac. It allows you to create custom rules that block any URL by providing a regular expression or hide any element by CSS. We stay independent, and the only way we make money is through direct sales of 1Blocker in the App Store to you.ġBlocker is a highly customizable content blocker, providing the possibility to create powerful custom rules. That's why we don't have an "Acceptable Ads" program. It doesn’t have access to webpages and doesn’t track you in any way. Some sites use techniques that make it impossible for us to block their ads using currently available features for Safari content blockers.ġBlocker is secure and private. It’s important to note that not all ads can be blocked though. So, with 1Blocker, sites load on average 2-5x faster. This vastly improves efficiency because Safari knows in advance what should be blocked. We only provide filters to Safari and don’t modify webpages in any way. The blocking itself is super fast because Safari does it itself. It’s lightweight and doesn’t drain your battery by taking up your device’s resources. It’s as simple as setting and forgetting.ġBlocker is a fully native app designed to extend Safari naturally. The app will automatically receive cloud updates to the built-in filters silently, so you don’t need to do anything. With 1Blocker, you’re safe online and nothing will distract you from enjoying sites.ġBlocker is very easy to use - just flip a couple of switches to start blocking ads and trackers. 1Blocker lets you block obtrusive ads, sneaky trackers, and annoying elements on sites.
