![]() ![]() Kısacası e-sigaralar güvenli mi? sorusunun cevabı, geleneksel sigaralardan çok daha güvenli olabilir. Bu özellikle tetrahidrokanabinol (THC) içeren vaping ürünleri için geçerlidir.

So we decided to give you a brief guide to some of the most impressive bridges in the Netherlands.Most visitors use a traditional South Florida airport such as Miami or Fort Lauderdale and drive south along US 1, the only access road through the Keys. Since there are so many bridges in this small country – Amsterdam being one of the cities with the most bridges in the world – it’s hard to cover them all. Let’s not forget about eco-ducts, the Dutch and Belgian passages carved into nature - they are good for the environment and pretty damn beautiful. Large, small, colourful, fancy, – it is bridge heaven over here! Especially when you see them being lifted for the first time, it can be quite a memorable experience for non-Dutch people.Ĭonsidering how many canals there is in the Netherlands, there are almost as many beautiful bridges to cross them.

In fact, advertisers are now spending more money on Android apparently because it’s now easier to track you there. However, most smartphone users worldwide use Android, where no similar feature exists. Recently Apple introduced App Tracking Transparency, a feature for iPhones and iPads that asks users in each app whether they want to allow third-party app tracking or not, with the vast majority of people opting-out. Companies hide trackers in your apps that can capture personal information. A report by AppCensus found similar results. Of those, 87% sent data to Google and 68% sent data to Facebook. Over 96% of the popular free Android apps we tested (based on rankings) contained hidden third-party trackers. With those profiles, tracking networks can manipulate what you see online, target you with ads based on your behavior, and even sell your data to other companies like data brokers, advertisers, and governments. This data enables tracking networks like Facebook and Google to create even more detailed digital profiles on you. Many of these trackers are designed to record your activity in real time: where you are, what you’re doing, where you’ve been, and even how many hours you sleep at night.Īcross all your apps, your personal data is being sent to dozens of third-party companies, thousands of times per week. These hidden app trackers are super creepy because they can track everything you do in an app and also can continue to track you even when you’re not using the app. You’ve probably heard about companies tracking you behind the scenes on smartphone apps they don’t own (like Google hiding in the Nike app).

Replays should have a tab mode that says how many gems you got, despawned, baddies killed, etc. Maybe a log of relevant events could get written to a file so that less hack-work would be involved in implementing ddstats. Replay mode's tab state is off by one or something. Like if you've got the time up while playing, it's not up in the replay. There should be more than 1 replay per player. What I'm thinking is, the top 6 longest, the 6 most recent, and up to 6 favorites. Maybe you can add titles to 'em as well? And maybe you can set playback to start at a particular time?

It’s denominated ‘W.’ It’s calculated by getting the product of volts and amperes. This shows the true measure of the amount of work done by electricity, represented by Watts. Volts units of measurement are denominated V. The difference in voltage between two points causes the movement between the two points. It is also known as potential difference. It measures the amount of force each electron is under or what causes electrons to flow. The unit of measurement for current is denominated A, as you will see in the calculations below. Using a water-flow analogy, we could say the amount of water in a pipe that moves from one point to another. It’s the number of electrons that move from point A to point B in a second. Still, they are as different as MIG and TIG welding.Ĭurrent indicates the flow of electricity from one point to another. The three main components used in Watts to Amperes calculation are often similar. It’s done to prevent short-circuiting in your equipment.

If not detected early enough, it can leave your house burnt down or have your air conditioner spoiled in a few days.Īlternatively, wrong results will lead to the frequent acquisition of circuit breakers. Getting wrong results on your calculations will lead to the purchase of cables that can’t withstand the current passing through them.

Nevertheless, CDXtract is still very easy to use, and its convert function now has even clearer context-sensitive options. However, the price rise from $79 to $139 means that CDXtract 4.0 has lost one obvious advantage over Translator, although Mac users will find that CDXtract 4.0 currently supports more formats. The new Stack, Switch and X-Fade functions are innovative, letting you create new layered programs with a few mouse clicks. Final ThoughtsĬDXtract 4.0 still doesn't offer image writing capabilities like Translator, but these are perhaps only of real interest to sound library developers. They aren't entirely intuitive to use, but tutorials will be available on the CDXtract web site. Switch and X-Fade are designed solely for HALion's Meta Trigg feature, and don't alter actual sample data - they just map it in different ways. CDXtract now lets you Merge programs from multiple locations, while Stack Mode and Controller Switching let you layer samples and switch between them according to velocity or mod-wheel position, with a X-Fade function to smoothly fade between them. The most intriguing new features are more creative. Like GigaStudio's QuickSound database, you can search using keywords like 'bass' or 'drum', which is a boon, while a Magic Player lets you easily audition files from CD-ROMs. Version 3's database has been replaced by a new one, which can store information about an unlimited number of CD-ROMs. ![]() Its own disk caching system is used when reading files, while conversion is done 'on the fly' and is noticeably faster. It can still read from most IDE, SCSI and USB drives, whether CD-ROM, Zip, Jaz or MO, and a new Virtual Drive function now lets you use Akai, Roland and Emu disc images stored on your hard drive. The New FeaturesĬDXtract 4.0 supports more sample formats than v3.6 (see box), and can convert from as well as to EXS24 and Giga formats, so you can use their libraries in HALion, for example. The Mac Translator, by contrast, lacks the full PC feature set. The PC version runs on Windows 98, Me, NT, 2000 and XP, while the identical Mac version runs on OS 8.6 and later (forthcoming OS X support will be in a free upgrade). Bernard has responded with version 4.0 of CDXtract, which for the first time is dual-platform. Chicken Systems' rival Translator (reviewed in SOS January 2002), however, could read more formats, sometimes provided more thorough conversions, and could write image files in various formats for burning onto CD-R.

A few compounds of krypton have been prepared, including krypton (II) fluoride and krypton clathrates.Īn important use is in high-powered, flashing airport runway lights. Krypton is a colorless, odorless, inert gas.Īlthough it is extremely unreactive krypton can react with the very reactive gas fluorine. Krypton glowing at high voltage in an electrical discharge tube. Not surprisingly, these pulses are of short duration: four billionths of a second. Krypton-fluorine lasers produce pulses with 500 times the power of the entire U.S. Krypton-85 in the atmosphere can be used to detect the presence of otherwise secret nuclear weapons research and production facilities. Krypton is not very abundant in our planet’s atmosphere: For every krypton atom, there are about 8200 argon atoms, 184 000 oxygen molecules and 685 000 nitrogen molecules. It is a white, crystalline solid, stable at temperatures below -30 oC. (The meter is now defined as the distance travelled by light in a vacuum during a time interval ofįrom its discovery in 1898 until the 1960s most scientists believed it was impossible to make compounds of krypton, or any other noble gas – although see William Ramsay, above. Radon was the only noble gas he didn’t discover.īetween 19, the scientific unit of length, the meter, was defined as 1 650 763.73 wavelengths of krypton-86’s orange-red spectral line. William Ramsay received the Nobel Prize for Chemistry in 1904, “in recognition of his services in the discovery of the inert gaseous elements in air, and his determination of their place in the periodic system.” He was responsible for adding an entire new group to the periodic table. It took another 60 years before his question would be answered. William Ramsay actually did believe compounds would be possible, writing in 1902: “I have had for a long time the idea that krypton and xenon may enter into combinations much more easily than the other gases but how to bring it about?” (3) Ramsay chose the element’s name from the Greek word ‘kryptos’ meaning ‘hidden.’įor many years after the noble gases were discovered most scientists believed that they would not form compounds. If it was not a compound, it had to be a new element. This value could only be obtained if the new gas consisted of single atoms, proving it could not be a compound. ![]() Ramsay and Travers measured the ratio of the gas’s specific heat at constant pressure to its specific heat at constant volume and found it was 1.66. He found Argon was present, as expected, but also two new brilliant lines, one yellow and one green, which had never been seen before. He placed a sample of the remaining gas in a vacuum tube and applied a high voltage to measure the gas’s spectrum. With this in mind, Travers removed oxygen and nitrogen from the gas using red-hot copper and magnesium. Ramsay knew it was highly improbable the new gas, lighter than argon, could be present in this residual sample, but the exciting idea came to him that a new, heavier, gas might just be present. ![]() In their practice work, they evaporated most of it, leaving just 100 ml. ![]() With little experience of handling liquid gases, they obtained a liter of liquid air in order to find out how to work with it. They would liquefy the argon, and then distil it into separate fractions to see whether the lightest fractions contained the new gas. Ramsay and Travers decided they would extract a large volume of argon from air. Ramsay wondered about the possibility of finding small amounts of the elusive new element hiding in one of his earlier discoveries, argon. Some years later Carl Gustaf Mosander discovered the new elements erbium and terbium in gadolinite they had been there all along, but Gadolin had not found them. For example, Johan Gadolin had discovered yttrium in the mineral we now call gadolinite. (1)Īware of the history of chemistry, Ramsay knew that sometimes one new element can hide another. And find it they did, but only after their search had first revealed another new element: krypton. They reasoned that a new element (it’s now called neon) must exist to fill this gap they were determined to find it. Ramsay and Travers considered the gap in the periodic table between helium and argon. He was aware that more new elements must lie in the same group of the periodic table. Ramsay had previously discovered helium and argon. Scottish chemist William Ramsay and his assistant English chemist Morris Travers discovered krypton in 1898 in London. ![]() |
