While I may not have had the best coffee or experience in every cafe I visited, from a physical perspective they all seemed quite well executed and fully realized.įor example, check-out that all-mesh draining work surface up above. One big trend in I noticed in Chicago, and a sure sign of a mature scene, was an overall attention to detail in cafe designs. In a city rife with roasting operations, and hometown beans showing up on guest hoppers across Chicago, Caffé Streets stands out for serving all out-of-town roasters: Heart, Verve and Sightglass on my visit. Caffé Streets wound up being an excellent place to start my tour because, excepting the noteworthy roaster difference, the cafe strongly reflected many of the trends I noticed in other cafes in the city. My first stop in Chicago was the design extravaganza that is Caffé Streets, a well-known multi-roaster shop in the Wicker Park neighborhood that opened in 2011. I can still hear the L rumbling as I type. Take them for what they are: the interesting, often pretty details that jumped out at one hyper-caffeinated barista from New York City, who took this trip as a Sprudge staff writer, but is publishing it today as the site’s Assistant Editor. So here, now, a few months after that visit, is a whirlwind two-part tour of four Chicago cafes: Caffé Streets, Gaslight Coffee Roasters, The Wormhole Coffee, and Bow Truss Coffee Roasters. I can’t claim to have a thorough understanding of the city after such a short time, and I was only able to visit each café once, so these aren’t reviews per se. Second, while the café culture and design tendencies here in Chicago clearly developed in relation to other major coffee cities, the robust Chicago scene definitely has its own distinct strengths, preferences, and aesthetic identity. First, while Chicago is a city where good coffee has been building momentum for a quite a while, the city seems to now be in the middle of its next phase of expansion, with many of the talented coffee people who came up in the city’s old-guard shops now striking out on their own and starting up new projects. I only had forty hours to spend in the city, which I admit is barely enough time to scratch the surface of the scene, but long enough to form a few first impressions. She named the shop 1890 because that is the year the train station opened, she said.Chicago is one of the major design, coffee, and culinary cities of America, and I finally had a chance to go see it for myself this past spring. I had come specifically because I was curious about how well Intelligentsia’s Logan Square concept actually worked-a subject I wrote about in-depth here-but I did manage to squeeze in visits to a few other local heavy-weights. She also commutes from the Harlem Avenue station to Chicago for her full-time job, so she thought the location would be perfect for her coffee shop. When I was in my early 20s, I thought about opening a shop but didn’t have the experience or education.”Īfter earning a master's degree in business administration from Robert Morris University, Tenorio developed a business plan and approached Berwyn officials about opening a shop in the empty space on the station’s platform. “The entire process of how coffee is made is very interesting. “I learned about the different flavors, the different beans and the different smells, and I knew I really wanted to do something with coffee,” she said. She said she knew from then on that she wanted to own her own shop. Tenorio has had a passion for coffee since her father introduced the beverage to her when she was a teenager. The shop serves a variety of locally roasted coffees and fresh pastries from Berwyn’s Vesecky’s Bakery, and it is open weekday mornings for busy Berwyn commuters. She’s the proud owner of 1890 Café, which opened June 1 at the Harlem Avenue Metra station in Berwyn. BERWYN – At just 29 years old, Berwyn resident Lissette Tenorio has made her dream of owning her own coffee shop come true. 1/15/2024 0 Comments Sequence game rules printableSimilar to other board games, the scoring criteria in Sequence is also relatively simpler. Other details regarding the scoring criteria for each player are mentioned below. Similarly, you can also remove your opponent cards using the anti-wild jacks. This can be carried out by using rare cards, especially dead cards, to overturn an unfavorable condition. The main objective of the game is to develop strategies regarding the cards and chips placement on board and gaining the upper hand over the competitors. For example, for three players, each player gets 6 six cards and so on. The number of cards available to each player decreases as the numbers of players increase in the game. In the case of 2 players, each player gets seven cards. There are around 104 sequence cards included in the game, which are divided among the team members. Along with this, you should keep in mind that all players must be evenly divided among all the teams. Three teams are the maximum limit for the game. The most important among which is the presence of no more than three teens. There are a variety of requirements that must be fulfilled while playing the Sequence. This helps in improving your performance and removing obstacles from your way. There is also a dead card in the game that can be used to draw a replacement card in case of a lack of available space on the board. Consumers can play these by placing their chips in any open space on the board.Īpart from wild jacks, there are four anti-wild jacks in the setting as well that can be played by eliminating the opponent chip from the board. There are four wild jacks in the cards, and they are two-eyed in nature. Once both teams have been created, the dealer is responsible for shuffling and handing the cards to the players.Īpart from this, different cards possess different features and thus, must be played carefully to avoid losing the points and achieve a remarkable victory. The game begins by dividing teammates evenly among all the teams. You can arrange them in a straight line, either vertically, horizontally, or diagonally depending on your preference. This board game involves five similar colored marked chips that are placed in a variety of positions on the board. So, here are some Sequence rules and tips on how to play Sequence, along with some insights into different cards and requirements of the game. Similarly, players are required to complete a sequence of similar chips to win the game. No more than three teams are allowed in a single round. The game can be either played by two players/teams or three players/teams. This multiplayer game focuses on making strategies in order to gain the upper hand over your competitors. If you like making strategies and want to think critically, Sequence is our ultimate recommendation to you. 1/14/2024 0 Comments Very best aa batteriesI remember my grandfather being like, 'You know, make sure you buy the super heavy duty one as opposed to the light wimpy one,' right? It significantly affected an entire generation of battery consumers." There's no reason to sell a zinc carbon system in 2022. "The jargon around that term dates back to the seventies and it worked. "It's incredibly confusing," according to Columbia University engineering associate professor Dan Steingart, who studies the capacity and energy efficiency of disposable batteries. The medium drain is similar to continuous use of a remote-controlled toy or gaming controller, while high drain is like a high-powered flashlight.ĭespite the E-Circuit and Panasonic carbon zinc being branded as "Super Heavy Duty," they were anything but, according to experts. They said the low-level drain is similar to the continuous use of a computer mouse or TV remote control. The researchers used the different drain scenarios - low, medium and high - to simulate real-life uses. But it was E-Circuit alkaline, a brand imported by and sold at Dollar Tree, that held its own against the more well-known brands, lasting nearly as long and costing only $1.25 for a pack of four. In the tests, which simulated different energy drain levels, Energizer and Duracell lasted the longest. The brands tested were Energizer, Duracell, Canadian Tire's Noma, Walmart's Great Value, E-Circuit from Dollar Tree, as well as Panasonic batteries from both Dollarama and Dollar Tree. Marketplace, teaming with researchers from Ontario Tech University in Oshawa, Ont., tested 240 double-A disposable batteries from six brands. Watch the full Marketplace investigation on CBC Gem. A CBC Marketplace test of double-A disposable batteries found that while major brand names deliver on their marketing promise to be long-lasting, batteries bought at two leading dollar stores did surprisingly well and provide good value for cost-conscious shoppers.īut the test also found that not all dollar store batteries are created equally and certain types of batteries did not perform well, with experts warning that they should be avoided despite their low cost. 1/14/2024 0 Comments Recipes deliciousWhat’s more, cannabinoid acids are more easily absorbed than their decarbed versions. But increasingly, researchers, physicians, and patients are recognizing the value of cannabinoid acids as well as other compounds found in the raw cannabis plant, which contains various enzymes, vitamins, minerals, protein, fiber, essential fatty acids, flavonoids, carotenoids, terpenes, and other polyphenols.Ĭoncentrated in the resinous trichomes of raw cannabis flowers and to a lesser extent on the leaves, cannabinoid acids such as THCA and CBDA offer a robust cornucopia of health benefits without any intoxicating effect. Thus far, medical scientists have focused primarily on the therapeutic properties of decarbed or neutral cannabinoids. This process also occurs naturally, though much more slowly, as dried cannabis ages. When decarboxylated at a particular temperature, these cannabinoid acids are converted into their neutral counterparts: THC, CBD, CBG, CBC, THCV, etc. (and the ‘A’ vanishes). The major and minor cannabinoids in raw, unprocessed cannabis plants are found in their acid form: THCA, CBDA, CBGA, CBCA, and THCVA. But that notion has proven to be way off the mark. It was once a common assumption within the cannabis community that plant cannabinoids aren’t “activated” or useful until they are “decarbed” - short for decarboxylated - which refers to the process of heating cannabis before it is consumed. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons in its nucleus. Hydrogen – Properties Summary Element Hydrogen Atomic Number 1 Symbol H Element Category Non Metal Phase at STP Gas Atomic Mass 1.0079 Density at STP 0.0899 Electron Configuration 1s1 Possible Oxidation States +1,-1 Electron Affinity 72.8 Electronegativity 2.2 1st Ionization Energy 13.5984 Year of Discovery 1766 Discoverer Cavendish, Henry Thermal properties Melting Point -259.1 Boiling Point -252.9 Thermal Conductivity 0.1805 Specific Heat 14.304 Heat of Fusion 0.05868 Heat of Vaporization 0.Atomic Number – Protons, Electrons and Neutrons in Hydrogen The Standard English unit is pounds mass per cubic foot ( lbm/ft 3). The standard SI unit is kilograms per cubic meter ( kg/m 3). In other words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. It is an intensive property, which is mathematically defined as mass divided by volume: Typical densities of various substances at atmospheric pressure.ĭensity is defined as the mass per unit volume. How does the atomic mass determine the density of materials? Density of Hydrogen The atomic mass number determines especially the atomic mass of atoms. The mass number is different for each different isotope of a chemical element. For 63Cu, the atomic mass is less than 63, so this must be the dominant factor. A nucleus with greater binding energy has lower total energy, and therefore a lower mass according to Einstein’s mass-energy equivalence relation E = mc 2. The nuclear binding energy varies between nuclei.This increases the mass of nuclei with more neutrons than protons relative to the atomic mass unit scale based on 12C with equal numbers of protons and neutrons. The neutron is slightly heavier than the proton.There are two reasons for the difference between mass number and isotopic mass, known as the mass defect: For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63, and an isotopic mass in its nuclear ground state is 62.91367 u. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol.įor 12C, the atomic mass is exactly 12u, since the atomic mass unit is defined from it. One atomic mass unit is equal to 1.66 x 10 -24 grams. The unit of measure for mass is the atomic mass unit (amu). Therefore this resulting atomic mass is calculated from naturally-occurring isotopes and their abundance. Note that each element may contain more isotopes. How does the atomic number determine the chemical behavior of atoms? Atomic Mass of Hydrogen Since the number of electrons is responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. 1/14/2024 0 Comments 20 x 25 x 5 cm wooden abacusYou can change your choices at any time by visiting Cookie Preferences, as described in the Cookie Notice.

While not technically a computer, the abacus is known as the first calculating tool. Beads are pushed to the center to mark numbers in different place values, making it easy to make complex calculations. This calculating tool uses a counting frame and a series of beads on an upper and lower set of rods. The Babylonians, Ancient Chinese, Japanese and Russians all used a calculating tool similar to a modern-day abacus. The abacus was either invented in Babylon or in Ancient China. It’s pronunciation is “a-buh-kuhs.”īecause the abacus is one of the first calculators created, its origin may predate the historical record. The abacus is believed to have been invented between 2,700 BC and 300 BC.Īn abacus is a calculating tool that’s been used for centuries and is still popular in many countries. The exact date of the invention of the original counting frame is unknown. patent # 4,037,200.Ībacus Explained - Everything You Need To Know FAQs (Frequently Asked Questions) He was also a member of the National Federation of the Blind.Ĭramer invented several devices, including a “Braille display switching matrix and circuit utilizing the same,” U.S. In 1952, he was employed by the Kentucky Division of Rehabilitation Services for the Blind. After being employed briefly at Kentucky Industries for the Blind, Cramer was a piano technician for 10 years. In his early years, he crafted and sold plastic jewelry. It can be used to perform addition, subtraction, multiplication, and division.Ĭramer was blind from childhood. The device is considered to be a valuable teaching tool for visually impaired students. It measures 6 1/8” x 3 1/4” and the bead diameter is 3/8”. This inexpensive, 13-rod abacus features a red felt backing which prevents beads from slipping during calculations. Shortly thereafter, the American Printing House for the Blind began selling the device, and they continue to sell it today. The Cranmer abacus is a modified version of the Japanese abacus or sorobon. The two possible binary digits are 0 and 1, but they are also described as low and high, which are the two possible positions for beads on an abacus. Binary digit, the numbering scheme used to encode and decode digital messages, is based on an abacus design. The abacus is also an ancestor of the modern calculator and computer. This origin, whether in Ancient China or Babylon, has been used throughout history and is continued to be used as a convenient calculator for commercial transactions. Abacus: Historical SignificanceĪs commercial transactions became more complicated, a calculating tool was essential to make quick calculations and avoid errors. It helps ensure quick calculations when working with large numbers and makes the calculation process visible to both buyer and seller or teacher and student. This counting frame allows individuals to track, add, subtract, multiply, and divide numbers easily. You can then push additional beads from the bottom or, if available, from the top to count up to nine in that place value. Pushing one bead from the top row to the center counts as five. Many designs have four or five beads on a bottom row, with one to five beads on the top row. Starting either with the tens place or a decimal place, increasing from right to left. The idea of this counting frame is that each rod represents a sequential place value. Ancient devices used marble or stone parts. Most abacuses are made of a frame with wood rods and beads. It’s a fairly straightforward calculator that is still used in many countries in schools or markets for counting. The woman in this illustration is Typus Arithmeticae, considered the “muse of arithmeti.” Abacus: How It Workedĭespite its long history and unknown inventor, the abacus has worked basically the same way throughout the centuries. 1/14/2024 0 Comments Xonotic monthly playersYou might already know about checking your ping and latency to improve your gaming experience. What is jitter? Jitter is an average of the change in ping over time or how your latency score fluctuates.īut there is one more factor that has a significant effect on the smooth gameplay you're supposed to have - and that is jitter. It is the variation in latency, and it's a problem because it makes the experience unpredictable. Average internet users commonly ignore it, but to online gamers, especially the ones who are playing multiplayer shooter games, this problem is a big deal. Jitter (or more accurately, latency fluctuation/flux), shows itself during games like Xonotic through choppy gameplay. You're running around, and suddenly the world freezes. Once it unfreezes, everything has changed, as if time had stood still for you and then got caught up suddenly. Even if this just happened half a second, you'll probably notice this stuttery gameplay. Jitter causes the latency to change rapidly, for example from 10ms to 80ms and back. i. In such a situation, it's tough for game servers to provide a fair environment for all players, which can be very frustrating. I know that a massive majority of players on here use keyboard and mice to play xonotic and will argue to the death that its the only way to play but i think this game could open itself to a big group of players if it was more couch/gamepad friendly. Rubberbanding is one of the major problems most gamers encounter when playing online games. This is extremely annoying, especially with Xonotic and online games with optimized-paced ‘twitch’ mechanics. Rubberbanding is a term used to describe a player's random or jerky movement in a multiplayer game when they're experiencing high latency. This often occurs in FPS or similar games that have a large number of people per multiplayer server. It is mostly seen in MMOs - a large number of players means there are more cases of rubber banding either the server is overloaded, or players have high ping. When rubberbanding happens, a player appears to be thrown backward from the start of the action after they executed that certain action. It feels like being caught in a rubberband - players get thrown back after moving forward, making it look like your character teleported or warped from one place to another. This rubberbanding problem is extremely frustrating, especially when you are in a crucial stage of the game. You’re hiding from your enemy and just about ready to shoot. |
