That procrastination-busting strategy is exactly what the pomodoro technique asks you to do: break down your big tasks, projects, or goals into something you only have to do for the next 25 minutes. Doing something small for a short period of time is a whole lot easier to face than trying to take on a big project all at once. Still too hard? Try just sitting down to edit a paragraph. For example, instead of sitting down to write novel, sit down to write for 5 minutes. Luckily, studies have also shown an effective way to break out of the avoidance cycle: shrink whatever it is you're putting off down to a tiny, unintimidating first step. So we turn to Twitter or Netflix instead to boost our mood, if only temporarily. It's uncomfortable to stare down a big task or project - one you may not be sure how to even do or one involves a lot of uncertainty. Rather, we put things off avoid negative feelings. Research has shown the procrastination has little to do laziness or lack of self-control. Here's what makes the method uniquely suited to boosting productivity: Making it easy to just get started The arbitrary silliness of using a tomato as a stand-in for units of time belies the Pomodoro Technique's serious effectiveness when it comes to helping people get things done. The Pomodoro technique is all about getting your mind in the zone to finish your tasks. If the system seems simple, that’s because it is. Keep an "Overlearning" project in Todoist with a list of tasks you can quickly choose from the next time you find yourself with pomodoro time to spare. For example, you could spend the extra time reading up on professional journals or researching networking opportunities. Use the rest of your time for overlearning, or improving skills or scope of knowledge. The rule applies even if you do finish your given task before the timer goes off. Cirillo recommends that you track interruptions (internal or external) as they occur and reflect on how to avoid them in your next session. In the event of an unavoidable disruption, take your five-minute break and start again. A digital task manager like Todoist is a great place for these, but pen and paper will do too. Any ideas, tasks, or requests that come up should be taken note of to come back to later. The pomodoro is an indivisible unit of time and can not be broken, especially not to check incoming emails, team chats, or text messages. For example, "write rent check," "set vet appointment," and "read Pomodoro article" could go together in one session. Any tasks that will take less than one Pomodoro should be combined with other simple tasks. Sticking to this rule will help ensure you make clear progress on your projects. If a task requires more than four pomodoros, it needs to be divided into smaller, actionable steps. The 25-minute work sprints are the core of the method, but a Pomodoro practice also includes three rules for getting the most out of each interval:īreak down complex projects. When your session ends, mark off one pomodoro and record what you completed.Īfter four pomodoros, take a longer, more restorative 15-30 minute break. Set your timer for 25 minutes, and focus on a single task until the timer rings. Though Cirillo went on to write a 130-page book about the method, its biggest strength is its simplicity: Encouraged by the challenge, he found a tomato (pomodoro in Italian) shaped kitchen timer, and the Pomodoro technique was born. Feeling overwhelmed, he asked himself to commit to just 10 minutes of focused study time. Cirillo was struggling to focus on his studies and complete assignments. The Pomodoro Technique was developed in the late 1980s by then university student Francesco Cirillo. Take the quiz Explore on your own What is the Pomodoro Technique?

This mentorship is usually given by serial entrepreneurs, founders, and investors, who have the knowledge and skills it takes to drive a new company to success. Making so many connections through a shared program can come in handy, especially when looking for investors, partners, or team members to boost your business even more.Īnother huge benefit of startup accelerators is personalized, often one-on-one, mentoring and guidance provided to founders. Established accelerator programs are communities of like-minded investors, program alumni, mentors, and other founders. One of the most significant benefits of joining a startup accelerator is the access it gives you to one-of-a-kind networking opportunities. 5 Benefits of Startup Accelerators 1) Networking Opportunities Some startup accelerators don’t even ask for any equity, particularly those run by colleges and universities. However, some accelerators ask for as much as 15% equity or as little as 1%. Almost all startup accelerators offer a lump sum in exchange for a certain percentage of equity in your company, usually around 5-7%. The amount of venture capital your startup can receive from an accelerator ranges from about $20,000-$150,000. Some programs even split time between different locations, allowing greater exposure to global networks and expanded learnings. While California naturally has one of the largest offerings of startup accelerators, there are programs worldwide. During this time, startup founders are often relocated to the program’s base, which may be in Silicon Valley or another global tech hub. Top companies: Cloudflare, Digime, NeuraĪ typical startup accelerator program lasts from 3-6 months.What they give: Check sizes from $1,000 to $150,000. How to apply: Start your application here.

There are more than 200 startup accelerators in the United States alone and many more worldwide. Most startup accelerators are open to supporting early-stage startups across different industries, but some focus on companies in specific sectors. Startups are usually admitted to accelerators in batches of a set size, with startup accelerators typically selecting 1-3 batches of new companies yearly. Still, there is generally some application and assessment process that founders must go through for a chance to be chosen. The selection process for every startup accelerator varies. Startup accelerators are usually fixed-term and offer a set amount of capital in return for a certain percentage of equity in the companies they select for their programs. These programs are designed to support early-stage startups with a minimum value product (MVP) to help them rapidly grow and scale. Startup accelerators are cohort programs for startup founders that offer mentorship, venture capital, and connections to potential investors and/or business partners. However, this is compensated in many other ways as they offer benefits for entrepreneurs looking to learn, make connections, and scale their businesses. It's important to understand that startup accelerators offer more than just capital, but the amount of capital you can get from them is small compared to other funding options. Some of the most well-known tech companies, such as Airbnb, Dropbox, and Stripe, went through accelerator programs in their early stages. Of these options, startup accelerators are one of the best tools available for helping new founders grow their businesses once they already have some traction.

They're really determined to represent that. And the people running the show, the people writing the show, Vincent Waller and Marc Ceccarelli, I think they really honor Steve's creation. "Stephen was able to keep that sense of cleverness and innocence at the same time, which is extraordinarily difficult. And obviously, I'm certainly eternally grateful, but he also, in a way, affected our culture, managing to mix his love for the ocean and for the creatures of the ocean with his love for animation. "What a unique, wonderful person he was," Fagerbakke says of Hillenburg. I saw all this incredible wit, and creativity, and rhythm, and color, and the depth of the culture of it. Hillenburg eventually resigned as showrunner following the third season, though he remained around as an executive producer and continued to offer advice alongside occasional, more direct involvement. From the start, he says Nickelodeon "handled really well," giving Hillenburg the freedom to develop SpongeBob organically, season by season. And he'd cast Tom, that was the first thing he did once he moved into the whole casting process, was he wanted that voice to be right.”īut at the heart of it, Fagerbakke keeps coming back to Hillenburg. Oh my God, Tom Kenny, it started with Tom. And Stephen cast it, I think, so perfectly. "But so many things have to fall in place, because at the end of the day, it is a collaboration between a lot of people. "Their creativity and their talent just knocks you out when you see the script," he says. He names a number of people central to its creation and continuation over the years, including his fellow voice actors, Derek Drymon, Aaron Springer, and members of the crew and art teams he doesn't normally get to work as closely with. Remembering Stephen Hillenburgįagerbakke says it's hard to precisely pin down what it is about SpongeBob SquarePants that has captivated audiences for so long. Over two decades, more than 200 episodes, 13 seasons, a number of movie and video game adaptations, and a pile of awards later, Fagerbakke's goofy, empty-headed sidekick character is now getting his own spin-off: The Patrick Star Show. It is now apparent, of course, that SpongeBob got its chance and more. Man, it was just, it was such a discovery for me.and then at that point, you just think, 'Well, I hope this thing gets a chance,' because you never know." "Just the coin dropped, and I finally got it. Several months later, Fagerbakke received the pilot episode in the mail: Help Wanted. Lens initially denied that the signing had been made, but it was finally confirmed on 2 June with an estimated price tag of £10m. The news initially broke following his Man of The Match performance in the opening FIFA World Cup 2002 1-0 group game vs France, who were the defending World and European Champions and one of the favourites to win the 2002 tournament. In early June 2002 he was reportedly linked with the English club Liverpool who had also just signed his club and international compatriot Salif Diao. He moved to Lens the following season, spending two years at the Pas-de-Calais. He made his debut appearance in a 2–1 win against Bastia on 12 November 1998, before moving to Rennes for the 1999–2000 season. Club career Early career ĭiouf started his career in France with Sochaux-Montbéliard. Early life īorn in Dakar, Senegal, Diouf came from a Serer background of the noble Diouf family. During his nine-year international career, he scored 21 goals in 69 caps, and also garnered considerable notoriety for a series of controversial incidents. He then moved to Leeds United where he spent two seasons. In 2011, he joined Football League Championship side Doncaster Rovers but was released at the end of the 2011–12 season following the club's relegation. He has also played in England's top flight for Bolton Wanderers, Sunderland and Blackburn Rovers before a stint in the Scottish Premier League with Rangers. Having started his professional football career in France with Sochaux, Rennes and Lens, Diouf finalised a move to Premier League side Liverpool prior to the 2002 FIFA World Cup for Senegal and went on to have a memorable tournament. Throughout his career, Diouf played as a winger or a forward. *Club domestic league appearances and goalsĮl Hadji Ousseynou Diouf ( French pronunciation: born 15 January 1981) is a Senegalese former professional footballer. Casting our attention to the present 2022–23 season, not much can be said aside from the word: The cetacean installation on Apsaved the remnants of last season, bringing 75" to Alta Ski Area during the month of April. The arrival of the whale correlates with enhanced snowfall along the Wasatch Range. Whales require salt water and there is no better place to harbor a benevolent powder whale than the valley of the salted lake. There is a synergistic quality to the whale occupying an arid high desert along the shores of one of the globe's saltiest lakes. Evan recently admitted "80% of the storms this season have performed above my forecast." There was simply no explanation for the sudden and unexpected arrival of all the late-season powder that could not be attributed to the arrival of the 9th and 9th Whale. Renowned local forecaster and powderhound, Evan Thayer of Open Snow, dug deep into the data and the modeling. Others quickly embraced the whale's whimsical colors and gigantic presence, the work of sculptor Stephen Kesler and muralist Mike Murdock.Ī pleasant surprise in a season so sunny, snow again returned to the Wasatch in April 2022 shortly after the whale made its initial splash. With it arrived a great deal of controversy as some neighbors expressed outrage at what they deemed an inappropriate symbol for Utah and the neighborhood. Without much warning, a life-size whale sculpture simply appeared "Out of the Blue," energetically breaching out of a long-neglected roundabout at 1100 East and 900 South in Salt Lake's trendy 9th and 9th neighborhood. The season seemed all but lost until the arrival of a certain cetacean on April 1st killed our streak of bad luck. A six-week dry spell spanning November and December was followed by days of high pressure in January which stretched out through all of February capped off by warm temperatures in late March that contributed to rapid melting. Utah's 2021–22 season was not a memorable one as far as our vaunted snowfall totals typically go. Not so very long ago, on the balmy but cloudy first day of April in the year 2022, a newcomer to Salt Lake City would forever alter the trajectory of The Greatest Snow on Earth®. The most notable include Zhuannian of Huairou District Donghulin of Mentougou District Shangzhai and Beiniantou of Pinggu District Zhenjiangying of Fangshan and Xueshan of Changping District. The artifacts date to 24,000 to 25,000 years ago and are preserved in the Wangfujing Paleolithic Museum in the lower level of the New Oriental Plaza mall.Īrchaeologists have discovered over 40 neolithic settlements and burial sites throughout the municipality. In 1996, over 2,000 Stone Age tools and bone fragments were discovered at a construction site at Wangfujing in the heart of downtown Beijing in Dongcheng District. The Upper Cave on Dragon Bone Hill in Zhoukoudian where remains of the Peking Man were found. Paleolithic homo sapiens also lived in the caves from about 27,000 to 10,000 years ago. The earliest remains of hominid habitation in Beijing Municipality were found in the caves of Dragon Bone Hill near the village of Zhoukoudian in Fangshan District, where the Homo erectus Peking Man (previously classified as the now-invalid species Sinanthropus pekinensis) lived from 770,000 to 230,000 years ago. From 1279 onward, with the exception of two interludes from 1368 to 14 to 1949, Beijing would remain as China's capital, serving as the seat of power for the Ming dynasty (1421–1644), the Manchu-led Qing dynasty (1644–1912), the early Republic of China (1912–1928) and now the People's Republic of China (1949–present). When Kublai Khan made Dadu the capital of the Mongol-led Yuan dynasty (1279–1368), all of China was ruled from Beijing for the first time. Its stature grew in the 10th to the 13th centuries when the nomadic Khitan and forest-dwelling Jurchen peoples from beyond the Great Wall expanded southward and made the city a capital of their dynasties, the Liao and Jin. During the first millennia of imperial rule, Beijing was a provincial city in northern China. Thus, the area that was to become Beijing emerged as an important strategic and a local political centre. The northern border of ancient China ran close to the present city of Beijing, and northern nomadic tribes frequently broke in from across the border. It was a provincial center in the earliest unified empires of China, Qin and Han. Prior to the unification of China by the First Emperor in 221 BC, Beijing had been for centuries the capital of the ancient states of Ji and Yan. The city of Beijing has a long and rich history that dates back over 3,000 years. Please discuss this issue on the article's talk page.

Signs of a clot in the kidneys can become severe and cause serious complications, such as problems with removing waste from the body and kidney failure (7). Pain in the abdomen, thighs and / or lower legs.Signs that a blood clot is affecting the kidneys include: Breathing difficulties (chest pain may worsen when inhaling or coughing causing breathing problems).Heart palpitations (an awareness of heart beats).Sudden shortness of breath (even when at rest and not in an active state). Signs that a blood clot has reached the lungs (signs of a pulmonary embolism / PE) include: If a clot occurs it can cause severe abdominal pain (especially if this continually worsens or becomes more acute after eating), nausea and vomiting, swelling (bloating), diarrhoea and blood in the stool (faeces) or vomit – potential signs of mesenteric ischemia. Mesenteric ischemia (abdominal area – mesenteric thrombosis): These arteries supply blood to the intestine.(6) Clots may form in the chest or neck area and also travel to the brain via the bloodstream, and potentially cause a stroke. Alternatively, a head injury that results in a concussion can also lead to the formation of a thrombus. Blood clots may develop in the brain as a result of fatty deposits in the walls of blood vessels supplying blood to the brain. Arteries in the brain (or carotid arteries in the neck): Sudden headache, loss of vision (visual disturbances), impaired, difficulties with or loss of speech, loss of concentration, body weakness (especially in the arms), difficulties with movement or walking, loss of sensation in the body (especially on one side, such as the limbs), facial drooping or seizures and loss of consciousness (signs of possible stroke or transient ischemic attack, known as a ‘mini stroke’ or TIA).in the left arm), and sharp pain which radiates from the centre to the jaw, arm or back – on the left side (signs of possible heart attack). myocardial infarction / heart attack): Indigestion, nausea, sweating, pressure in the chest (likened to a heavy feeling – an elephant sitting on the chest) or chest pain (angina), shortness of breath, rapid heart rate, cough, light-headedness (or loss of consciousness), numb or cold sensations (i.e. Signs of an arterial blood clot often depend on its location in the body: Tissues then effectively begin to sustain damage and die, often resulting in a medical emergency. Signs of blood clots which have formed in the body’s arteriesĬlots in the arteries can quickly become dangerous as blood is not able to be pumped to an affected area, which in turn deprives tissues of essential oxygenated blood supply (known as ischemia). A large clot may cause extensive swelling and pain in, for instance the entire leg, as opposed to just the calf area. Most often, symptoms affect one area, such as one arm or leg, or side of the pelvis (clots affecting both limbs at the same time, for instance are very rare). Such symptoms are often experienced in the legs or arms over the course of a few hours and vary in severity depending on the size of the thrombus. Skin discolouration (red, bluish or blanching / pale)īlood clots that occur in the deeper veins of the body effectively prohibit the flow of blood back to the heart.Pain and or / tenderness (likened to a muscle cramp or charley horse – a sudden involuntary muscle contraction / spasm).Inflammation or redness on the skin surface (in and around the affected area).Warm sensations (near the site of the clot / general area which may also sometimes be itchy).
Indeed, the latest steel construction specifications published by AISC (the 14th Edition) no longer cover their installation. High-strength bolts have largely replaced structural steel rivets. Until relatively recently, structural steel connections were either welded or riveted. Women rivet heaters, with their tongs and catching buckets, Puget Sound Navy Yard, May 1919 2000 during work to reinforce the structure to resist seismic loads. High-strength structural steel rivets An original structural steel rivet from the Golden Gate Bridge (1937). Solid rivets are also used by some artisans in the construction of modern reproduction of medieval armour, jewellery and metal couture. Applications where only one side is accessible require "blind" rivets. Solid rivets are driven using a hydraulically, pneumatically, or electromagnetically actuated squeezing tool or even a handheld hammer. The setting of these fasteners requires access to both sides of a structure. Steel rivets can be found in static structures such as bridges, cranes, and building frames. "Ice box" aluminium alloy rivets harden with age, and must likewise be annealed and then kept at sub-freezing temperatures (hence the name "ice box") to slow the age-hardening process. Some aluminium alloy rivets are too hard to buck and must be softened by solution treating ( precipitation hardening) prior to being bucked. Typical materials for aircraft rivets are aluminium alloys (2017, 2024, 2117, 7050, 5056, 55000, V-65), titanium, and nickel-based alloys (e.g., Monel). Such rivets come with rounded (universal) or 100° countersunk heads. Hundreds of thousands of solid rivets are used to assemble the frame of a modern aircraft. A typical application for solid rivets can be found within the structural parts of aircraft. Solid rivets are used in applications where reliability and safety count. The woman on the left operates an air hammer, while the man on the right holds a bucking bar. Riveting team working on the cockpit shell of a C-47 transport at the plant of North American Aviation. A rivet compression tool does not require two people and is generally the most foolproof way to install solid rivets. This tool is mainly used on rivets close to the edge of the fastened material since the tool is limited by the depth of its frame. A rivet compression or crimping tool can also deform this type of rivet. Solid rivets consist simply of a shaft and head that are deformed with a hammer or rivet gun. Solid rivets are one of the oldest and most reliable types of fasteners, having been found in archaeological findings dating back to the Bronze Age. Solid/round head rivets A typical technical drawing of a universal head solid rivet There are several types of rivets, designed to meet different cost, accessibility, and strength requirements: The rivets themselves were essentially short rods of metal, which metalworkers hammered into a pre-drilled hole on one side and deformed on the other to hold them in place. Archeologists have also uncovered many Bronze Age swords and daggers with rivet holes where the handles would have been. Rivet holes have been found in Egyptian spearheads dating back to the Naqada culture of between 44 B.C.

However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft).įastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term rivet was introduced and, where they are remembered, are usually classified among nails and bolts respectively. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.īecause there is effectively a head on each end of an installed rivet, it can support tension loads. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. The end opposite the head is called the tail. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end.
