Where Que took broad steps, Epic is surveying the scents under the shelter inch by inch, searching for a whiff of egg mass. Epic's nose doesn't seem to leave the ground as he checks every nook and cranny near a handrail. He gets worried if he doesn’t succeed right away.Įpic leaps from his crate ready for his turn, and takes his time, combing the shelter more thoroughly. While Que is confident, Bontrager said Epic is younger and a little more uncertain. “Yes! Good job!" Bontrager said before returning him to his crate. He yips excitedly at the smell until zeroing in on the spot and paws the scent tube. In less than a minute, Que catches the odor. “When the harness goes on," Bontrager said before leading Que into the shelter, "the dogs know it’s time to work.” The longer time periods result in the more pungent tube, which are more easily discovered.īontrager will set the tubes out and train the dogs one at a time for short, 10– to 15-minute sessions.Īt Happy Hollow Park on a recent morning, Que is the first to try to find three tubes spread out under a shelter housing picnic tables.īontrager puts on Que’s working harness, offers a separate tube so Que knows what to smell for and gives him his treats. The exposure times range from 12 to 48 hours. ![]() Que and Epic now train on tubes that have been stored with live egg masses. It was a breakthrough, and Bontrager found a biology professor, Collin Hobbs at Huntington University, who was willing to help. This is when she discovered Getxent, a type of plastic tube that absorbs and hold odors for about six months. ![]() It turns out, there is even a difference in the scents of a frozen egg mass and a live mass in nature. “I was just not figuring out why they couldn’t figure it out in the field,” Bontrager said. That person put her in touch with someone in New York working on the same invasive insect problem. The problem stumped Bontrager until she reached out to a conservation dog trainer in North Carolina. Que and Epic showed real progress training with these but started to struggle in the field as they transitioned from trying to find the frozen samples to the actual masses in the wild. The lab could put the eggs into a freezer that reached -80 Celsius and would keep them there for 96 hours. She obtained eggs that had not hatched, but because those cannot be taken outside, she had to kill off the eggs with the help from a lab in Purdue University. Initially, they used egg masses that had already hatched, but Bontrager soon learned those have a different odor than live egg masses. The odor from insects is not perceptible to humans, so she started by making sure Que and Epic knew how to search for odors, then moved on to the scent of the plant hopper's egg mass. ![]() The scent is paired with food so it becomes a habit: when they find it in the field, they’re rewarded with a treat and praise.įor Bontrager, the process started with a lot of learning on the fly. How are the dogs trained?īontrager began training Que and Epic last year. Bontrager set up crates and fans in her vehicle and will stop at parks to train when she’s done with her nursery inspections for the day. “Now my dogs get to go to work with me all the time,” Bontrager said. For Bontrager and her dogs, the new endeavor is a win-win project. Other states have purchased conservation canines trained for this work, but there are constraints on state-owned dogs, such as how they’re kenneled. “I asked if they mind if I try and train my dogs to do this." “That really caught my attention because this is the newest upcoming threat and I thought we’re probably going to see it here,” Bontrager said. Her unique action was inspired by a video of a similar approach in Pennsylvania, where the species is more prolific. So it was only logical that she decided to combine her skills to help fight against the pest. Invasive species: 10 to watch out for across Indiana When she's not working for the state, the La Porte woman's trains and shows dogs. She spends her days traveling to big-box garden centers and small nurseries to make sure there are no invasive insects or diseases on plants being sold to customers.

For this price, however, it's also pretty replaceable. Some users have also reported that their units broke or malfunctioned quickly, though it does come with a three-year satisfaction guarantee. On the downside, it has only three speeds (low, medium, and high) and three preset programs (smoothie, milkshake, and salsa). As a bonus, the blender comes with a 24-ounce plastic cup that screws right onto the blade base for a quick and easy single-serving smoothie to go. It has a 1,200-watt motor that can tear through tough ingredients like kale, and comes with a heavy-duty glass pitcher that’s dishwasher-safe and resistant to thermal shock. This Oster model offers high power and quality at a very affordable price. (If you're planning to upgrade from another Vitamix model, you should note that older attachments are not compatible with the Ascent series.) This is a super-powerful luxury blender, sold for a luxury price. And the machine senses the attachment automatically, adjusting its settings and options accordingly.īut then there's that eye-watering cost. ![]() There are also small bowls and cups you can use to take a smoothie or dip to go. These include a food processor, a container for milling grain into flour, a special aerating blade for whipping cream, shaking cocktails, and making emulsified sauces and dressings. There are a bunch of useful Vitamix Ascent accessories available, too. It can bring soup to steaming in about 10 minutes, and we used it to make a smooth, lump-free chocolate pudding even faster than on the stovetop. Maybe the most impressive thing it can do is cook food: The blades can spin so fast that the friction heats up the contents of the jar. We put the A3500 through its paces and found amazing results with smoothies, peanut butter, whipped cream, cheesecake batter, potato pancakes, and mayonnaise-this is a really versatile machine. The Ascent comes with 10 speeds and five on-board blending programs, plus wireless connectivity and the Perfect Blend app, which lets you control the blender from your phone as well as download new programs for all sorts of specific recipes. Vitamix's top-of-the-line model is only a tiny bit more powerful than the Explorian above, but it's a heck of a lot smarter. Vitamix A3500 Ascent Series Smart Blender Review The 48-ounce pitcher, made of heavy-duty, BPA-free plastic, is a bit smaller than some of our other picks as well, but it's dishwasher-safe. The control panel here is very basic, offering 10 different speeds and a pulse function but no preset programs. (This even worked after making sticky peanut butter!) What most impressed us, however, it how easy it is to clean: Add a drop of dish soap and hot water, then run for a few seconds. Its 1,400 watts of power breeze through smoothies, sauces, dips, hot soups, doughs, nut butters, non-dairy milks, and more. ![]() In our head-to-head testing of Vitamixes, the Explorian performed just about as well as the rest. It's still not cheap, but it's hundreds less than the brand's flagship Professional Series. The Explorian range is Vitamix's new entry-level blender, offering high power at a more manageable price. Its blenders are expensive, but their incredible performance and durability makes them worth the high price tag. Vitamix has long been considered the gold standard of high-performance blenders and is still the brand favored by many professional chefs for its power, design, and durability. Here are the machines we've found to be the best high-powered blenders. There's no official standard as to what constitutes a high-powered blender, but we tested dozens of blenders and dug through online listings and reviews, focusing on the ones in the top range of wattage. Some can even make hot soups-using either a built-in heating element or the power of friction produced by blades spinning at high speeds-and many offer connected smart functions and self-cleaning programs. Good design can help minimize these issues, but nothing makes a blender more effective than simply more power.īlenders with higher wattage tend to be more expensive than weaker models, but they can handle tough ingredients and thick consistencies well enough to produce velvety smoothies, silky nut butters, and sleek sauces. They can overheat, require a lot of stopping and starting in order to scrape down the sides, and often fail to blend ingredients to a smooth consistency even if you add more liquid and blend for a long time. A blender is usually a kitchen necessity, but lower-powered blenders can be incredibly frustrating to use. ![]() The standard Nintendo Switch package includes: What's included with a Nintendo Switch Console? Nintendo strayed far from the beaten path with its Nintendo Switch console design. The creative design of the Switch includes a tablet body that measures 6 inches, along with detachable controllers with wireless function. But what makes the Nintendo Switch unique is that it also doubles as a handheld game system. ![]() On one hand, the Nintendo Switch console provides users with a fully functional game console for their homes. Nintendo took a bold step forward with its Nintendo Switch console. So, for now, we'd take a look at this range of cheap MicroSDXC Nintendo Switch-friendly cards.Get Your Game On With Nintendo Switch Consoles Nintendo also has its own branded cards, but you'll be paying more just for a label. What memory cards does the Nintendo Switch need? Those will be Micro SD cards, also known as, depending on their size, MicroSDHC (up to 32GB) or MicroSDXC (up to a huge 2TB soon). Don't fret, though, they're actually surprisingly cheap, with even 64GB ones coming in at under £20/$25. ![]() With only 32GB of internal storage on the base model and 64GB for the OLED variant, you'll be wanting to pick up a cheap memory card or two for your new Nintendo Switch for any digital purchases or the inevitable game-fixing patches. Better yet, if your friends own a Switch, ask them to bring their controllers to the party! Nintendo Switch MicroSD card deals We'd buy the Joy-Con as a pair (see our comparison chart above) as you'll save a bit of cash over buying them separately. ![]() However, if you want to play four-player games, then you're going to need to invest in an extra pair of Joy-Con controllers or some Pro controllers. So you get multiplayer functionality straight out of the box with no additional purchase required. We've seen 2K's NBA series, Snipper Clips, FIFA 19, and Mario Kart being used this way for local multiplayer in both docked and tablet modes. Possibly not! Remember how the Joy-Con controller splits in two? Turn them sideways and you get two basic controllers, each with its own analog stick and face buttons - the d-pad acts as face functions on the left controller. For the best and biggest savings, you're always better off waiting for the likes of Amazon Prime Day and Black Friday which take place in the summer and winter respectively.ĭo I need to buy more Nintendo Switch controllers for multiplayer? Outside of special sales events, most of the big retailers in the US, the UK, and Australia will run discounts intermittently throughout the year. Where can I get the best Nintendo Switch deals? We've seen games effectively receive discounts of up to 50% when bought as part of a bundle. These games have been developed and produced by Nintendo itself, so that means games such as The Legend of Zelda: Tears of the Kingdom, Metroid Dread, and Animal Crossing: New Horizons.Īs these titles do not usually fall much below their usual price (even years after launch), your best option to get them for cheap is as part of a Nintendo Switch bundle. The best games in a Nintendo Switch bundleĪs mentioned above, first-party releases are the games you'll want to look for to get the best Nintendo Switch bundle deals. For this reason, it's always worth double-checking the going price of the bundled game you're picking up against the overall cost to make sure you're getting a good deal. Nintendo Switch sales outside of busy shopping periods (Black Friday or the holidays) are more likely to try this tactic. In this case, it's worth picking up a Nintendo Switch bundle with a full $60 game and grabbing the cheaper title separately if you're desperate to play it. Games readily available for $20 - $30 can sneak their way into the premium-priced deals, lowering the overall value of the offering. Many retailers often include cheaper games with their Nintendo Switch bundles and still charge standard price. Just because Nintendo Switch bundles are cheap might not mean they are good deals.

Transistors have been made very small (dozens of atoms wide) so that billions of them can be put into a small computer chip. If not for the transistor, devices such as cell phones and computers would be very different, or they might have not been invented at all. The transistor is a very important component today. Brattain, John Bardeen, and William Shockley who contributed the most. Three physicists were credited with the invention of the transistor in 1947: Walter H. Unfortunately, tubes were big and fragile, used a lot of power, and didn't last very long. Vacuum tubes were important in household technology before transistors. The triode served the same purpose of the transistor 50 years earlier. The transistor was not the first three terminal device. Transistors can be also made from compounds like gallium arsenide. Researchers are also studying transistors made from special forms of carbon. Germanium, another group-14 element, is used together with silicon in specialized transistors. Transistors are made of semiconductor chemical elements, usually silicon, which belongs to the modern Group 14 (formerly Group IV) in the periodic table of elements. In a MOSFET used as an amplifier, transistors take the flow of the drain and source, and since the source current is so much larger than the drain's current, it is common for the drain's current to rise to the value of the sources, amplifying it. This rivals the mechanical switch, which requires a constant force pressing on it. When the gate of a P-channel MOSFET is positively charged, electricity will flow through, this is useful for electronics that require a switch to be turned on, making it an electronic switch. This means that you can control the same amount of current with a very small amount of current going into the base. ![]() One of the transistors is connected so that it controls the current to the base of the other transistor. The basic Darlington transistor circuit is formed from two bipolar transistors wired emitter to base so they act as one transistor. The "B" stands for base, the "C" stands for collector, and the "E" stands for emitter. The circuit symbol of a Darlington transistor. The water is the electrons, and when you positively charge the gate, it unbends the hose, letting water flow. The transistor can also work when the gate is just positively charged, so it doesn't need to be touching the drain.Īn easy way to think of how a transistor works is as a hose with a sharp bend that stops the water from going through. ![]() This is because when the gate is positively charged, the positive electrons will push other positive electrons in the transistor letting the negative electrons flow through. But when power flows through the gate (or base), the transistor will allow electricity through. When the source (or emitter) is connected to the negative terminal of the battery, and the drain (or collector) to the positive terminal, no electricity will flow in the circuit (if you have only a lamp in series with the transistor). Transistors have three terminals: the gate, the drain, and the source (on a bipolar transistor, the wires can be called the emitter, the collector, and the base). When the center pin is powered, the power can flow. Mail and imediatelly you see 4 copies of what you're Knows what, many times eating 100% of the CPU.
