![]() Use the undo button to go back and try another column. Empty columns: try to empty columns as quickly as possible and use them as temporary storage to see under cards that are face down, to check if they are useful.You can only do this if there is at least 1 card in each column. You must deal new cards when you can no longer move any cards. So, it is a good idea to arrange the cards by colour as much as possible when starting the game. However, complete sequences can only be cleared to the foundation if they belong to the same suit. For example, a Jack of Clubs can be placed on a Queen of Hearts. When playing with 2 or 4 suits, you can simply move cards to other cards that are one point higher in value, irrespective of the colour. This functions largely in the same way as playing with a single suit, except that you need to take the colours into account. Furthermore, it is important to know that you can place any random card in an empty column and that you go back one step using the undo button. Whenever you move a card that was face down, the previously hidden card will be turned up. For example if the 7, 6, and 5 of Spades are on top of each other, then you can move all three at the same time to an open 8. It is also possible to move several cards at once, if they are all in ascending order with a one point difference. The most important rule of the Spider Solitaire game is that you can only place a card on top of another card that is 1 point higher in value.įor example, you can only place the 2 of Spades on the 3 of Spades (see illustration). ![]() It is played with just one suit: Spades! In this game, you do not need to take account of the colours when moving the cards. Level 1 is played differently from the other two levels: 1 suit Our Spider Solitaire game has 3 levels: 1 colour (easy), 2 colours (more challenging), and 4 colours (extremely challenging, only for the real expert). Once you have completed a sequence, it will automatically be moved to the foundation and you can start on the next sequence and so on, until you have cleared the whole tableau. For this purpose, you must arrange all cards in the tableau in descending order in the same suit, from King to Ace. The aim of Spider Solitaire is to move all cards from the tableau to the foundation. ![]() The Foundation will ultimately contain all 104 cards, sorted by colour and in order from King to Ace, arranged in 8 stacks.Each column in the tableau gets a new card whenever you tap on this stock. The Stock contains the 50 cards that have not yet been dealt.Here, around half (54 cards) of the 104 cards in play are arranged in 10 columns. The Tableau is the section in which the game is played.To fully understand how to play Spider Solitaire, we will first take a look at the playing field. It is played by 1 person only and uses 2 decks of cards. ![]() Spider is a Solitaire game made popular by Microsoft Windows. ![]()

![]() ![]() The creators of the format pronounced the acronym GIF as / dʒ ɪ f/, with a soft g, with Wilhite stating that he intended for the pronunciation to deliberately echo the American peanut butter brand Jif, and CompuServe employees would often quip "choosy developers choose GIF", a spoof of Jif's television commercials. The most common pronunciations in English are / dʒ ɪ f/ ⓘ (with a soft g as in gin) and / ɡ ɪ f/ ⓘ (with a hard g as in gift), differing in the phoneme represented by the letter G. ![]() The pronunciation of the first letter of GIF has been disputed since the 1990s. Main article: Pronunciation of GIF A humorous image announcing the launch of a Tumblr account for the White House suggests pronouncing GIF with a hard g. The press's lexicographers voted it their word of the year, saying that GIFs have evolved into "a tool with serious applications including research and journalism". In 2012, the American wing of the Oxford University Press recognized GIF as a verb as well, meaning "to create a GIF file", as in "GIFing was the perfect medium for sharing scenes from the Summer Olympics". Terminology Īs a noun, the word GIF is found in the newer editions of many dictionaries. In January 2018 Instagram also added GIF stickers to the story mode. In May 2015 Facebook added support for GIF. The optional interlacing feature, which stores image scan lines out of order in such a fashion that even a partially downloaded image was somewhat recognizable, also helped GIF's popularity, as a user could abort the download if it was not what was required. The feature of storing multiple images in one file, accompanied by control data, is used extensively on the Web to produce simple animations. In 2004, all patents relating to the proprietary compression used for GIF expired. Controversy over the licensing agreement between Unisys and CompuServe in 1994 spurred the development of the Portable Network Graphics (PNG) standard. While GIF was developed by CompuServe, it used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm patented by Unisys in 1985. In September 1995 Netscape Navigator 2.0 added the ability for animated GIFs to loop. GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM. By December 1987, for example, an Apple IIGS user could view pictures created on an Atari ST or Commodore 64. The two versions can be distinguished by looking at the first six bytes of the file (the " magic number" or signature), which, when interpreted as ASCII, read "GIF87a" or "GIF89a", respectively.ĬompuServe encouraged the adoption of GIF by providing downloadable conversion utilities for many computers. As there is little control over display fonts, however, this feature is rarely used. allowing text labels as text (not embedding them in the graphical data).storage of application-specific metadata.In 1989, CompuServe released an enhanced version, called 89a, This version added: This version already supported multiple images in a stream. The original version of GIF was called 87a. Since this was more efficient than the run-length encoding used by PCX and MacPaint, fairly large images could be downloaded reasonably quickly even with slow modems. GIF became popular because it used Lempel–Ziv–Welch data compression. This replaced their earlier run-length encoding format, which was black and white only. History įurther information: § Unisys and LZW patent enforcementĬompuServe introduced GIF on 15 June 1987 to provide a color image format for their file downloading areas. These replacements, in turn, are often termed "GIFs" despite having no relation to the original file format. While once in widespread usage on the World Wide Web because of its wide implementation and portability between applications and operating systems, usage of the format has declined for space and quality reasons, often being replaced with video formats such as the MP4 file format. GIF images are compressed using the Lempel–Ziv–Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients but well-suited for simpler images such as graphics or logos with solid areas of color. It can also represent multiple images in a file, which can be used for animations, and allows a separate palette of up to 256 colors for each frame. The format can contain up to 8 bits per pixel, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. The Graphics Interchange Format ( GIF / ɡ ɪ f/ GHIF or / dʒ ɪ f/ JIF, see § Pronunciation) is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite and released on June 15, 1987. ![]() ![]() ![]() It continues to be a popular brand of cordless battery-powered, corded electric, and gas-powered outdoor equipment.

Ryobi tops out at 1.1 GPM while consumer 3000 PSI gas pressure washers average around 2.0 GPM. While Ryobi nails the entry-level PSI pressure needed for a true homeowner product, gas still typically offers great water flow rates (GPM). Indeed, it removes the need for most maintenance you’d associate with a typical gas pressure washer. The upside is that the Ryobi RY143011VNM requires no gas or oil. Ryobi designed this electric pressure washer to put out enough pressure to compete with entry-level gas-powered models. ![]() ![]() ![]() The first factor is the spring mechanism. When choosing durable alligator clips, there are several factors to consider. Stainless steel is highly resistant to corrosion, making it the best material for alligator clips that will be exposed to harsh environmental conditions. Brass and copper are excellent conductors of electricity however, they tend to corrode over time. The most common materials used in manufacturing alligator clips are brass, copper, and stainless steel. Additionally, consider the size and shape of the object you will be connecting to, as well as any specific features or requirements that may dictate the type of alligator clip you choose. If safety is a concern or you will be working with high-voltage equipment, an insulated alligator clip may be necessary. If you need a stronger grip or durability for heavy-duty applications, an angled-jaw alligator clip may be a better choice. If you need a simple and affordable connector for general-purpose use, a straight-jaw alligator clip may be sufficient. To determine which type of alligator clip suits your needs, consider the application and environment in which you will be using them. However, they may be more expensive than non-insulated alligator clips, and their insulation may limit their use in certain situations. The advantages of insulated alligator clips include their safety features, as well as their ability to prevent accidental contact with live wires or conductors. Insulated alligator clips are commonly used in high-voltage applications or situations where safety is a concern. These clips have a plastic or rubber coating on the handles and jaws, providing insulation and protection against electric shock or short circuits. The third type of alligator clip is the insulated alligator clip. However, they may not be as versatile as straight-jaw alligator clips, and their angled design may limit their use in certain applications. The advantages of angled-jaw alligator clips include their ability to grip onto irregular shapes and surfaces, as well as their durability and strength. Angled-jaw alligator clips are commonly used in automotive repairs or other applications where a stronger grip is necessary. These clips have jaws that are bent at an angle, allowing for a better grip on larger objects or surfaces. The second type of alligator clip is the angled-jaw alligator clip. However, they may not be suitable for heavy-duty applications or situations where a more secure grip is required. The advantages of straight-jaw alligator clips include their simplicity and affordability, as well as their ability to grip onto small wires or components. These clips have straight metal jaws that open and close parallel to each other, and they are often used for general-purpose applications such as testing circuits or attaching wires. ![]() The first type of alligator clip is the classic straight-jaw alligator clip. Recognized brands and their reputation for producing high-quality alligator clips are also discussed, along with how to balance price and quality when making a purchase decision. Additionally, it provides information on the materials used to manufacture alligator clips, factors to consider when choosing durable alligator clips, and tips on maintaining their durability. This article outlines the advantages and disadvantages of different types of alligator clips and how to choose the appropriate size and strength for specific applications. With different types of alligator clips available in the market, it can be challenging to determine which type suits your needs. Alligator clips are an essential tool for anyone working with electronics or electrical systems. ![]() ![]() ![]() The Elder Futhark runic alphabet was such an ideal system: there are as many Elder Futhark runes as there were sounds in the Proto-Norse language, for which they were developed. ![]() The ideal alphabet has a separate symbol (letter or rune) for each sound the language has. Now if we are to spell it in the Elder Futhark runes, we have to look deeper into what spelling is and have a look at the following facts: You may want to have inked in runes the name of a beloved one, your own name, or a name of a deceased person who was important in your life. Many runic tattoo designs include a name. Perhaps you wouldn’t like to be in such a situation with your runic inscription, would you? The name is well known in India because of Queen Victoria, so the person who developed the tattoo design probably wasn’t a native Hindi speaker and even did not know the language well. The tattoo read Vihctoria instead of Victoria with additional h. David Beckham inked his wife’s name on his left forearm in Hindi but misspelt it. Online translation tools may play a trick on you: a woman who wanted to have “I love David” in Hebrew on her back, later realized the actual tattoo said “Babylon is the world’s leading dictionary and translation software”. Tattooed inscriptions in foreign languages or written in unusual characters may well be a source of trouble, especially if you don’t know well the language or the writing system. If you are about to have a Norse or Viking tattoo, I bet you want to include some Nordic runes into it. ![]() Developing a great design for a tattoo is critical in case you seriously plan to get inked. ![]() ![]() ![]() Hyper- or hyporeactivity to sensory stimulationįor a person to meet criteria, characteristics must be present during a child’s early development.Preoccupation with objects or topics of interest.Presence of restricted or repetitive patterns of behavior.In the DSM-5, because communication and social skills operate together, they are now combined.Ĭharacteristics may include the following: In the DSM-IV, communication and social were seen as two separate areas. Impairment in social communication and interaction.Question: What are the DSM-5 characteristics?ĪNSWER: Under the newest changes, the DSM-5 diagnostic criteria for Autism Spectrum Disorder require the person to demonstrate characteristics in two categories. Preoccupation with objects or topics of interest or with parts of objects.Presence of restricted, repetitive, or stereotyped patterns of behavior.Difficulty developing peer relationships.Limited ability to engage in imaginative play.Question: What were the diagnostic criteria in the DSM-IV?ĪNSWER: Previously, the DSM-IV diagnostic criteria required the person to demonstrate characteristics in three categories.Ĭharacteristics may have included the following: This new change reflects the idea that this disorder is a spectrum and that every individual with ASD is unique in their abilities and challenges. The DSM-5 will now use the overarching term Autism Spectrum Disorder and allow clinicians to indicate levels of severity. In addition, Rett's Syndrome is now considered a completely separate disorder. The terms Asperger's Syndrome, Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), and Childhood Disintegrative Disorder are no longer included in the definition. In this fifth edition of the DSM, as we have learned even more about the disorder, the definitions and terms have changed yet again. These four terms plus Autistic Disorder were grouped together under the label of Pervasive Developmental Disorder and included individuals with both severe and subtle challenges in their level and type of communication or social ability. Also included at that time were the disorders Childhood Disintegrative Disorder, Rett's Syndrome, and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS). In 1994, with the release of the DSM-IV, the definition was modified to include the term Asperger's Syndrome for the first time. As research and our understanding of ASD advanced, these same behaviors were classified as a separate disorder in 1980, at first called infantile autism and later changed to autistic disorder. This disorder was classified with childhood schizophrenia and the label given to only those with the most severe challenges. In the earliest versions of the DSM, ASD was not well understood, and the term "autistic-type behaviors" was used. The original versions provided narrow definitions, which were expanded more broadly in later years. Although first defined as a mental health disorder, it was later correctly placed under neurodevelopmental disorders. Question: What is the history of ASD in the DSM?ĪNSWER: As you can see from the timeline, both the term and the definition of Autism Spectrum Disorder have changed many times over the years. It is not intended to be used in any way to identify or diagnose ASD. The purpose of this fact sheet is to act as a source of information regarding the definition of ASD according to the most recent version of the DSM. Such assessments are to be completed by trained medical personnel such as developmental pediatricians and psychologists. Instead, making a differential diagnosis requires a clinician to gather records and information about a person’s past history, conduct observations, interview caregivers, and conduct assessments designed to aid in the identification of ASD. At this time, no medical test exists for the diagnosis of ASD. Question: What is the purpose of this fact sheet?ĪNSWER: It is important to remember that making a diagnosis of ASD is a complicated matter. The DSM 5th edition (DSM-5), released in May, 2013, provides the latest definition of ASD based on what science and research have uncovered over time. This manual is used by clinicians and researchers to diagnose and classify disorders, including ASD. One way to view this progression is through the many revisions of the Diagnostic and Statistical Manual of Mental Disorders (DSM) published by the American Psychiatric Association (APA). Due to years of research in a wide variety of fields, our understanding of what ASD is and what it looks like in different individuals has changed dramatically over time. What we know now is far beyond what we once believed. Defining and understanding Autism Spectrum Disorder (ASD) is a constantly evolving process. ![]() ![]() ![]() Rather than memorize facts and figures for each element, students and scientists need only glance at the table to learn much about the reactivity of an element, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics. The Periodic table is useful for modern students and scientists because it helps predict the types of chemical reactions that a particular element is likely to participate in. Element 106 has been named seaborgium (Sg) in his honor. In 1951, Seaborg was awarded the Nobel Prize in chemistry for his work. He reconfigured the periodic table by placing the actinide series below the lanthanide series. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. With the discovery of isotopes of the elements, it became apparent that atomic weight was not the significant player in the periodic law as Mendeleev, Meyers and others had proposed, but rather, the properties of the elements varied periodically with atomic number. This charge, later termed the atomic number, could be used to number the elements within the periodic table. van den Broek in a series of two papers proposed that the atomic weight of an element was approximately equal to the charge on an atom. In the popular imagination the periodic system invariably and justifiably connects to his name, to the same extent that the theory of evolution connects to Darwin’s name and the theory of relativity to Einstein’s.Īlthough Mendeleev's table demonstrated the periodic nature of the elements, it remained for the discoveries of scientists of the 20th Century to explain why the properties of the elements recur periodically. Mendeleev’s version of the periodic table left the biggest impact on the scientific community, both at the time it was produced and thereafter. ![]() However, there was an untimely delay in the publication of his most elaborate periodic table, and, perhaps more importantly, Meyer-unlike Mendeleev-hesitated to make predictions about unknown elements. The closest precursor to Mendeleev’s table in both chronological and philosophical terms was developed by Julius Lothar Meyer, a German chemist, in 1864. ![]() By the 1860s a number of scientists had moved beyond the triad concept to produce some very respectable periodic systems. The elements in these groupings displayed an important numerical relationship to each other: the equivalent weight (an early substitute for atomic weight) of the middle element had the approximate mean of the values of the two flanking elements. The observation that certain types of elements prefer to combine with certain other types prompted early chemists to classify the elements in tables of chemical affinities. Mendeleev was hardly the first to arrive at a periodic system. It marks the 150th anniversary of the publication by the Russian chemist Dmitry Mendeleev (1834–1907) of his Periodic Table and celebrates the significance and impact of this outstandingly successful chart of the atomic building blocks of matter. The year of 2019 was designated by the United Nations as the International Year of the Periodic Table of Chemical Elements.

![]() ![]() Maybe it’s because I have a fully flat drain cover. ![]() ![]() The vacuum valves are all set correctly, yet the vacuum still gets caught on the drainage system. This may not be the only reason pool, however. It’s worth noting that some vacuum cleaners can’t run at low RPMs with three-speed or variable-speed pumps.Īccording to several professionals, if the pool vac gets caught on the main drain, you have not correctly set your suction. The returning hydraulic pressure could be directed at a spot where the cleaner is stuck to assist in moving the hose out of the corner, enabling the unit to clean the pool more successfully and reducing maintenance while also increasing wear on the cleaner’s head. Usually, the water returning to the pool from the pool pumping should not interfere with the original direction of the pool cleaner nevertheless, modest changes in the route can equalize the pool’s covering. A flow stopper valve is the most straightforward approach. However, without suction, the pool will not be effectively cleaned. The more powerful the water flow, the more probable it is to become stranded in one location. Adjusting the FlowĪdjusting the flow of water through it allows you to modify the suction. In other circumstances, determined by the shape of the pool, having more or less hose is worthwhile you may not get entire exposure of the pool, but you might remove the risk of getting trapped. This will fluctuate based on the sort of pool cleaner you use since some demand various hose lengths. For most pools, the sizes of the skimmer baskets plus one meter from the pool’s farthest border are optimum. Length of the HoseĬhoosing a hose length is indeed not hard, based on the scale and form of your swimming pool. The precise placement of a hose’s weight can allow the hose to travel under or over the skimmer box. Most customers mistakenly place the hose weights near the department’s top, thinking that this is where they should be. Hose weights are used to keep the pool cleaner’s head, or “machine,” balanced on the pool’s top. Lay down flat so that the memory returns to the factory hose. If a section of the pool hose is coiled, lay it out in the sunlight. If you only have less storage space, make sure the hoses aren’t left on rough surfaces. When storing pool hoses of any length, whether single or multi-meter, it’s preferable to detach them and arrange them straight beside each other.
