How did Goldstein prove the existence of protons in an atom? As a result, he reasoned that the particles in the cathode ray were negative. Thomson found that the path taken by the cathode ray could be bent towards a positive metal plate, and away from a negative metal plate. Why did JJ Thomson conclude that the particles were negatively charged? Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. What did JJ Thomson’s cathode ray tube experiment prove? Thomson discovered that the mass of the particles in cathode rays was 1800 times lighter than hydrogen, the lightest element. Johann Hittorf discovered cathode rays in 1869 using a Crookes tube and noting shadows cast on the glowing wall of the tube opposite of the cathode. What did the cathode ray experiment prove? Accordingly, he called his particles electrons. Thomson’s discovery established the particulate nature of electricity. With both magnetic and electric deflections observed, it was clear that cathode rays were negatively charged particles. Thomson’s plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged “soup.” Did the cathode ray have positive or negative charge? What experiment proved electrons carry a negative charge? Millikan discovered that there is a fundamental electric charge-the charge of an electron. Thomson’s cathode ray tube showed that atoms contain small, negatively charged particles called electrons. What evidence supports the existence of negatively charged particles?Īlthough no one has actually seen the inside of an atom, experiments have demonstrated much about atomic structure. The negative electrons represented the raisins in the pudding and the dough contained the positive charge. He demonstrated that cathode rays were negatively charged. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. How did Thomson’s evidence prove that electrons are negatively charged? Thomson used the cathode ray tube to determine that atoms had small negatively charged particles inside of them, which he called “electrons.” Electrons were first discovered as the constituents of cathode rays. How does the cathode ray tube experiment proved the existence of electrons?Ĭathode rays carry electronic currents through the tube. He observed that cathode rays were deflected by a magnetic field in the same manner as a wire carrying an electric current, which was known to be negatively charged. In order to determine if the cathode ray consisted of charged particles, Thomson used magnets and charged plates to deflect the cathode ray. How it was proved that cathode rays carry negative charge?

These smaller species of African cichlids generally grow to be no more than five inches and can be kept in a tank of 2030 gallons.When mature, these parasites give rise to cysts that contain numerous flagellated, small, free-swimming stages that can initiate new infections The pathogenic stages of the organism are pigmented, photosynthetic, nonflagellated, nonmotile algae that attach to and invade the skin and gills during their parasitic existence. In regards to the tiger barbs, that does make sense. I really can't tell from the pictures whether this redness is something more than that or not. They don't seem as aggressive as my zebra so hopefully I can keep them, but we'll see what happens. Red Zebras do have a reddish tinge around their gills as part of their natural coloring. I really need to identify my 2 other cichlids so I can make a decision on them as well. These parasites produce a disease that has been called "velvet," "rust," "gold-dust," and "coral disease" because of the brownish gold color they impart to infected fish. Yeah, parting ways with my Red Zebra is pretty much inevitable at this point, unfortunately. Its freshwater counterpart, Oodinium spp, is less common but can also result in high mortality. One of the most serious health problems of captive marine fish is the parasitic dinoflagellate Amyloodinium spp. Archived from the original on 3 March 2016.

You’ve likely had a great deal of experience with the lower-level thinking skills (yellow section). Creative thinking is the second focus of this chapter.Īll of these thinking skills are important for college work (and life in the “real world,” too). This skill will make you stand out in college and is in very high demand in the workforce. This process is the most difficult mental function. Putting parts together or reorganizing them in a new way, form, or product. Critical thinking is the first focus of this chapter. This skill encompasses most of what is commonly referred to as critical thinking this skill will be called on frequently during your college years and beyond. Critiquing the value and usefulness of material. You most likely started developing this skill in high school (particularly in science courses) and will continue to practice it in college.Īssessing, making judgments, and drawing conclusions from ideas, information, or data. Mental actions included in this skill are examining, contrasting or differentiating, separating, categorizing, experimenting, and deducing. This skill is commonly used starting in middle school (in some cases earlier).īreaking material or concepts into key elements and determining how the parts relate to one another or to an overall structure or purpose. Using learned material or implementing material in new situations. Reading is the most common understanding skill these skills are developed starting with early education. Interpreting, constructing meaning, inferring, or explaining material from written, spoken, or graphic sources. This is the first and most basic thinking skill you develop (starting as a toddler with learning numbers, letters, and colors). Retrieving or repeating information or ideas from memory. Figure 3.2 “Types of Thinking Skills” outlines each skill and what is involved in that type of thinking, as updated by Lorin Anderson and David Krothwohl. He lists six types of thinking skills, ranked in order of complexity: knowledge, comprehension, application, analysis, synthesis, and evaluation. So what are the various types of thinking skills, and what kind things are we doing when we apply them? In the 1950s, Benjamin Bloom developed a classification of thinking skills that is still helpful today it is known as Bloom’s taxonomy. Identify how each type of thinking contributes to learning.Understand that there are different types of thinking. It is worth noting that, Boycott Advance cannot emulate the classic Gameboy.

Place the cut-out top of the bottle upside down in the bottle. Turn on your LED candle and put it at the bottom of the bottle. The goal is to provide something for the kissing bugs to crawl up the tape to the top of the bottle, so apply lots of vertical tape strips from top to bottom. Wrap the remaining 2/3 of the bottle with packing tape all around. Use the packing tape to line the outside of the bottle. The best part of making your trap is the lack of harsh chemicals and reusing items.Ĭut off the top 1/3 of the bottle with the knife, leaving a funnel to flip and put back into the bottle. These bottle traps help keep kissing bugs out of your house while also killing any already there. You most likely already possess everything you need to complete this trap. How to Kill Kissing Bugs with a DIY Bottle TrapĬreate an efficient DIY kissing bug trap for very little money at home. Kissing bugs can’t see the yellow light from energy-efficient LED bulbs and therefore aren’t attracted to the entrance of your home where they could slip inside. Yellow light bulbs are specifically tinted to repel insects. If you’ve observed a lot of insects surrounding your outdoor lights, consider replacing them with yellow light bulbs. Bright lights attract flies, mosquitoes, moths, and kissing bugs. Using a porch light at night offers security to the home, but it draws unwelcome insects. How to Get Rid of Kissing Bugs Using Yellow Light Bulbs Learning how to kill kissing bugs is critical for disease control and preventing insect bites from leading to an allergic reaction or worse. These wingless insects are pests and cause a nuisance, though they have no bearing on sexual health despite their name. Like spider bites, the assassin bug has a painful and itchy bite. The condition basics include acute illness, fever, fatigue, and inflammation of insect bites.ĭue to the dangers associated with this pest, understanding how to get rid of kissing bugs from cracks and crevices in your home or your box spring is essential. The Western Conenose bug carries the Trypanosoma cruzi parasite, which bug infestations pass to humans through their kissing bug bite.Īccording to top medical providers like the Mayo Clinic and Hartford Healthcare behavioral health library, Chagas disease, an inflammatory, infectious disease, is caused by triatomine bugs or the kissing bug. If you live in the United States southern regions, Central America, or South America, you’ve probably spotted them and want to know about getting rid of vampire bugs.
He also completed a 10-yard pass to Eric Moore.ĭefensively, Schatzman, Jarrick Roger, Antonio Greaves and Gerald Kinchen all registered tackles-for-losses as South smothered Island Coast. He threw a perfect bomb to Cedrick Clarke for a 43-yard touchdown. Quarterback Andre Polk was a first-down machine as he gained at least 10 yards on all four of his rushes for 43 yards. He flashed his speed by racking up 115 yards on 11 carries while picking up blocks along the way from players such as Schatzman, Stanley, Rick Rodriguez, Junior Pereira, Patrick Ziolkowski and Howie Wehrenberg. Kennedy picked off an Island Coast option pass on the first play of the game and then proceeded to rush for four touchdowns from 19, 5, 38 and 29 yards. James Kennedy made sure the night started on the right note for South Fort Myers in more ways than one. South stamped an exclamation point on its season with a 35-0 win in the season finale against Island Coast on Oct. We've got pretty much every position here that will keep rolling in the next three years," Causey said. They said we were short on skill players," said fullback, linebacker and co-captain Micario Stanley.Ī deep roster is an indication that South doesn't appear to short on anything. "It was tough, but we outplayed all the teams," said lineman and co-captain Ryan Schatzman. South scored more than 30 points in six games, posted five shutouts and allowed just two touchdowns all season, one to Lehigh and one to Fort Myers. A 29-0 win against Riverdale was the closest call. South used size, strength and speed to its advantage as the Wolfpack won every game by a margin of at least four touchdowns. "I got rid of the 'me, me, me' and let them know it's all about South and the team." "When you're giving up so few points, it's a challenge to get your team motivated each week and to go out and play to their best ability, but they believed and they did it. It was good to have a big team, but also to have a big team that can move and be fast."ĭespite having lopsided games every week, South never lost its focus. It makes me happy because you see where South is headed," Causey said. This season's unblemished freshman record came under the guidance of James Causey, whose team overwhelmed opponents to the tune of a 293 to 12 scoring advantage. Richard Keast was at the helm of the 2009 squad, whose players are now seniors on South's undefeated varsity team. Joe Hampton was the head coach for the first two. The perfect season marks the fourth time in the South's eight-year history that the freshman team has gone undefeated. That's what South's class of 2016 did as the Wolfpack concluded a jaw-dropping freshman campaign with a 7-0 record. How about allowing 12 points for an entire season? We're not talking about 12 points in a quarter or in a half or even in a game. Their season had just ended when a few players on the South Fort Myers freshman football team wondered aloud about those 12 points the Wolfpack allowed. 27: South Fort Myers 42, North Fort Myers 0 2012 South Fort Myers' freshman football resultsĪug. Int trigger = 13 // machine gun trigger motor connected here Proteus simulation of the H-bridge:ĭownload Proteus H-Bridge Simulation: h bridgeĪrduino Camera Tracking Controller Programming: int hmw1 = 7 // horizontal motor wire1 For the practical demonstration watch Video tutorial given at the end. This H-bridge Module will be used to rotate the platform on which the machine is fixed. Then I tested this circuit using Proteus simulation software. I have also used the same h-bridge in the tongue controlled wheelchair. The relays normally open, normally closed and common contacts are connected with the dc gear motor in such a way that by turning on and turn off the relays the motor direction can be controlled. As you know in the circuit diagram above, an h-bridge is used to control the direction of the dc motor. I selected 2n2222 NPN transistor because it has a low price, easily available in electronics shops, you can think of the 2n2222 NPN transistor as the cockroach of the electronics world. You can use any NPN transistor so far its collector current is greater than the relay coil current. The relay coil resistance can be found using the digital multi-meter and then using the ohm’s law The selection of the transistor depends on the relay coil current needed to energize the relay coil. The driver simply consists of the 2n2222 NPN transistor and a 10k resistor. This relay has total of 5 pins, two coil pins, common pin, normally open and normally closed. This relay is of the type SPDT which stands for the single pole and double throw. This gear motor is controlled using a 12v Relay. The machine trigger is controlled using a 12v gear motor.

IPVanish’s pricing is around average, working out at £8.25 per month, £22.27 for three months and £52.84 per year. We’d ideally like to see it have its privacy policy independently audited. However, there’s no indication of what, if any, changes have been implemented to ensure this.īearing that in mind, it’s safest to assume that IPVanish keeps detailed connection logs until it’s proven otherwise. Current owner J2 Global, like StackPath before it, says it intends to honour its no-logging guarantee. However, in 2016, when it was owned by its original parent company Highwinds, IPVanish handed over detailed connection information for use as evidence to the Department of Homeland Security, even though it claimed to keep no logs at the time. which doesn’t require logging of user activity by law but also has few data protection requirements and a record of state surveillance. IPVanish has a no-logging policy and is based in the U.S. However, it’s still no good at UK streaming services iPlayer and All4. It’s not bad at streaming US media services, either, with Netflix and Shudder both working well. Its US endpoints, as is often the case, performed brilliantly, with another significant speed boost over last month putting it among the fastest services for those who need to virtually travel to North America, at 102.8Mbps over HTTP and 140.8Mbps via FTP. Its Netherlands endpoints were a bit slower than last month, particularly via HTTP, which clocked in at 78.16Mbps, with FTP transfers producing a rather faster 105.96Mbps. IPVanish’s UK performance – previously among its weak points – improved significantly on last month, although it was still slightly below average with throughput of 107.36Mbps (13.42MB/s) via HTTP and 131Mbps via FTP on our ultra-high-speed test connection. The IPVanish Windows client supports OpenVPN, L2TP and PPTP connections, has a number of extra security features including leak protection, a kill switch to ensure that you never send data across the internet without the protection of the VPN, and can connect automatically on boot.Ĭlients are also available for macOS, Android, iOS and Amazon’s Fire TV, as well as details on how to connect other devices such as Linux PCs, Windows phones, and routers.

IPVanish has over 1000 servers in more than 50 countries across Europe, North America and Asia, with a few scattered endpoints on other continents. You can choose your endpoint country from a map or filter by latency. IPVanish is easy to use, with a well-designed Windows client that includes a traffic and speed graph, and connection options that allow you to let it choose the best endpoint for your chosen country or city, or manually select from its available endpoint servers.Įndpoint auto-selection didn’t always produce the best results for us, so we were pleased by the level of fine-grained manual endpoint selection available. It is an established and well-regarded name in VPN provisioning, with generally strong performance in our throughput tests from its Dutch and U.S. IPVanish is a long-time part of the VPN (virtual private network) landscape that’s been bought and sold by a number of different companies, most recently tech and publishing giant J2 Global.
The Remington UMC pranaut that was made by Camillus is a little smaller than a Case peanut, but I just love how it functions day to day, doing all my cutting jobs, from plastic blister packages, to opening my mail, and slicing some snack from the fridge. But I find that all ego aside, these little guys do everything Ineed of a pocket in the course of the day in the life of a retired machinist living in a typical American suburb. As you can see, the Vic classic, and Leatherman squirt have blades much smaller than the peanut, and the sliding blade Christy knife is as long but much thinner. In our modern life, we don't really need much knife. You'll enjoy the heck out of it! I use the heck out of all my little knives, some of which are smaller than a peanut. Especaillyt if you plan on urban/sububan carry, opening packages, slicing a thread off your clothes, cutting a piece of twine for the tomato plants, all jobs I've found that a small knife does very well. Plus the toothpick is a pretty little thing with a design that harks back to the Spanish navaja.ĭo you plan to fend off a grizzly bear with a knife? Or fight off Chinese paratroopers? Or survive the Amazon jungle with your toothpick? If the answer to these are not, then the toothpick is good for you. After all, the peanut does all I need, so the toothpick will too. I've thought about a tiny exam toothpick as a companion piece to my peanut. I find that with the exemption of food preparation and survival use, a small knife does all I need. Then one day I woke up from a bad dream, sold them all off, and have been carrying smaller knives ever since. Living in a modern suburban life, it's hard to justify a 7 inch bladed combat knife like the Ranbdall 14, one of my favorites. I had a collection of Randall's and other high end customs all large fixed blades that never got used. The Texas Toothpicks are currently performing throughout the southwest branding listeners with thier own roots country style and ability to sing sweetness into. I love knives, and in the past it got out of hand. I find I have to keep in mind just who and what I am. I can go for days using nothing else to open my mail, UPS boxes, plastic packaging, and the occasional string or jute twine. One of my most used knives is not even as big as a tiny toothpick, the Victoriox classic. I became a peanut size knife enthusiast, and never went back. My dad was a die hard Case peanut guy, and once I got to middle age and the young and dumb factor faded, I realized that a small knife taking up less space in my pocket was a good thing. I've been a very long time champion of the little knives and came to that over a long period of evolution and years of knife use. To be down to earth practical, the little Texas toothpick can be use for anything you'd use another small knife for. |
