Hematite is formed during weathering and oxidation of iron-bearing rocks in mountainous areas. Cryptocrystalline varieties of the stone have a cherry color. Most specimens are black, gray, or brown with a statement metallic sheen. Hematite is one of the mineral varieties of iron oxide. With hematite, it was possible to recognize the signs of fate and subjugate other people to one’s will. The stone established itself as a conductor of superpowers. Alchemy and magic rituals couldn’t do without the mineral. ![]() The unique mineral with a metallic luster was very popular during the Middle Ages. Sorcerers, witches, and shamans had hematite mirrors which helped them build tunnels connecting the worlds of the living and the dead. Items crafted from the mineral had not only an aesthetic purpose but also magical properties since they were supposed to protect their wearers from diseases and witchcraft. The North American Indians used hematite powder to apply warlike designs to their skin.Īncient times were the golden age of hematite jewelry. It was credited with the ability to ward off demons and evil spirits. In Egypt, the mineral was considered the stone of Isis, the goddess of life. Before a battle, they put on hematite objects to avoid injuries, as well as to enhance their strength, courage, and faith in victory. Warriors and knights relied on the stone as a protective amulet. Ancient Romans believed that hematite was petrified blood, and it could be found at the sites of battles and sacrifices. ![]() Such associations have a reason - in addition to the bloody tint the mineral showcases, it is able to turn the water red. It was suggested by the Greek poet and philosopher Theophrastus who noticed the similarity between the stone and blood. The mineral received its current name in the third century BC. If you enjoy impressive-looking gems with powerful positive vibrations, you should give hematite a chance. The stone is known since antiquity but its aesthetic and decorative qualities had been underappreciated for a long time. It hides a red streak behind its metallic luster. Physicochemical Properties of HematiteĪlthough hematite is associated with blood, you shouldn’t confuse it with bloodstone.

"Universal" or "multi-standard" sockets are intended to accommodate plugs of various types. Wiring systems where both circuit conductors have a significant potential with respect to earth do not benefit from polarised plugs. In some designs, polarised plugs cannot be mated with non-polarised sockets. For example, appliances may ensure that switches interrupt the line side of the circuit, or can connect the shell of a screw-base lampholder to neutral to reduce electric shock hazard. Where a " neutral" conductor exists in supply wiring, polarisation of the plug can improve safety by preserving the distinction in the equipment. ![]() Class I equipment requires an earth contact in the plug and socket, while Class II equipment is unearthed and protects the user with double insulation. The assigned IEC appliance class is governed by the requirement for earthing or equivalent protection. The plug is often designed so that the earth ground contact connects before the energized circuit contacts. Some early unearthed plug and socket types were revised to include an earthing pin or phased out in favour of earthed types. Some types can also include fuses and switches.Ī third contact for a connection to earth is intended to protect against insulation failure of the connected device. Sockets may have automatic shutters to stop foreign objects from being inserted into energized contacts. Contact pins may be sheathed with insulation over part of their length, so as to reduce exposure of energized metal during insertion or removal of the socket. Sockets may be recessed and plugs designed to fit closely within the recess to reduce risk of a user's fingers contacting the live pins. Plugs are shaped to prevent finger contact with live parts. Protection from accidental contact ĭesigns of plugs and sockets have gradually developed to reduce the risk of electric shock and fire.

Depending on the supply system, one or both current-carrying connections may have significant voltage to earth ground. Single-phase sockets have two current-carrying connections to the power supply circuit, and may also have a third pin for a safety connection to earth ground. To reduce the risk of electric shock, plug and socket systems have safety features in addition to the recessed contacts of the energised socket.Ī socket may be surrounded by a decorative or protective cover which may be integral with the socket. Some plugs have built-in fuses for safety. Some plugs have female contacts that are used only for an earth ground connection. The plug is a male connector, often with protruding pins that match the openings and female contacts in a socket. Typically no energy is supplied to any exposed pins or terminals on the socket, for safety.Ī plug is the movable connector attached to an electrically operated device, and the socket is fixed on equipment or a building structure and connected to an energised electrical circuit. Clockwise from top left: CEE 7/4 (German) plug a matching CEE 7/3 socket with exposed earth (ground) projections on circumference of socket CEE 7/5 (French) socket with projecting earth pin. Plugs and sockets may sometimes combine male and female contacts. Some multi-standard sockets allow use of several types of plug improvised or unapproved adaptors between incompatible sockets and plugs may not provide the full safety and performance of an approved socket-plug combination. ![]() Coordination of technical standards has allowed some types of plug to be used across large regions to facilitate trade in electrical appliances, and for the convenience of travellers and consumers of imported electrical goods. Today there are about 20 types in common use around the world, and many obsolete socket types are found in older buildings. A proliferation of types developed for both convenience and protection from electrical injury. Plugs and sockets for portable appliances became available in the 1880s, to replace connections to light sockets with wall-mounted outlets. Different standard systems of plugs and sockets are used around the world. ![]() Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type.

![]() George Starcher and Duane Waddle’s talk on the KV Store was very informative. It was a great showcase of commands that aren’t used often because people don’t realize their power. Kyle Smith’s talk on lesser known search commands was also interesting. Once you realize how Splunk breaks terms into tokens and then searches you begin to think about new ways to construct searches so that they are faster and more efficient. Martin Mueller’s session on “Fields, Indexed Tokens and You“ was very interesting. There were also some very good sessions given by some of the SplunkTrust members.

![]() There is the possibility of some hardware announcements too, including perhaps new wireless earbuds, a new MacBook update and maybe even a glimpse of the augmented reality glasses. While WWDC is not usually the base for new hardware announcements, we could however see a slight diversion from the usual. This year however, there is that potential extra edge. Apple is changing Siri’s trigger phrase from Hey Siri to just Siri. WWDC 2021 is where, as it is every year, the company is expected to give us a sneak peek at the future of the software side of things-iOS, iPadOS, watchOS, macOS, tvOS, App Store, services, apps and more, and is focused more on the developers and the software roadmap, than consumers. For the iPad, the iPadOS 15 gets widgets with larger sizes that can be put in between apps on the Home Screen, a new App Library that was already available on the iPhone, the new Focus mode as well as Live Text and tweaks to multitasking in case you are using it for work. The highlights for iOS 15 include the really cool Live Text feature that can pull out test from your photos, richer search results in Spotlight, an updated Weather app, FaceTime updates including Spatial Audio as well as SharePlay and the new Focus mode and greater notification control. One key highlight so far has been the evolution of FaceTime – it’s (almost) ready to go after Zoom and Google Meet! Apple’s new headset is called Vision Pro, and you can read all about it in our WIRED story (weve got more details in our hands-on experience ). WWDC21 program is revealed, and will be available free to the more than 30 million Apple developers from 227 regions around the globe WWDC21 kicks off with a keynote address June 7 at 10 a.m. The Apple Worldwide Developers Conference kicks off with exciting reveals and new opportunities. We summarize all the big changes coming to the iPhone, iPad, Mac and Apple Watch later this year. Some notable highlights include: Triggering Siri by just saying, 'Siri. WWDC 2021 has brought a ton of new software from Apple (though no new Macs, as had been rumored). Apple has previously hosted the event at the McEnery Convention Center in San Jose, California, but the ongoing COVID-19 pandemic has made that impossible. watchOS 8 has some new stuff, and your new operating system for Macs will be called macOS Monterey, among other things. As is typical with WWDC, there are a lot more additions and improvements to iOS 17 than Apple showed during the keynote. Apple is expected to announce iOS 15 at WWDC 2021 The WWDC 2021 event starts Monday, June 7, and runs through Friday, June 11. Apple WWDC 2021 live event has happened, and we have seen the first glimpses of iOS 15 for your Apple iPhone, iPadOS 15 for your iPad as well as other goodies including the rollout of Spatial Audio for Apple Music and the confirmation of the wider audio feature for Apple TV’s tvOS as well. ![]() Step 2: Configuring Sublime Text for Python Select the version of your OS system and follow the installation instructions. If you haven’t already done this, you can download Python from. You also need to have Python set up on your computer. exe file to complete the installation process. How to set up Sublime Text for Python development Step 1: Download Sublime Text and have Python set up on your computer Learn more about how to utilize AI to optimize your software engineering in 2023. Keeping abreast of new technologies and practices ensures that you are equipped with the knowledge and skills needed to succeed in this dynamic field. To remain relevant in the constantly changing landscape of software development, it is essential to stay up-to-date with the latest advancements and trends. Keep up with software development’s evolving field In a way, packages can be seen as extensions that are pluggable into Sublime to perform whatever task you want. This includes plugins, syntax highlighting customization, menus, and code snippets. The highlight for Sublime Text is the ability to extend the current functionality with a thing called Packages. Sublime Text comes with a core set of rich features such as key bindings, indentation preferences, spell checks, multi-select, and file patterns. You don’t need to worry about accidentally editing the wrong files when you’ve got more than a dozen files open. Sublime Text preserves your open projects and keeps them separated from each other. Some IDEs and code editors only allow for one project at a time. ![]() The separation can come in handy when you’re referencing multiple codebases. Instead, it opens up a completely new window for you to arrange as you wish on your screen. ![]() Opening up a new project won’t close your current project either. Sublime Text’s beauty lies in its minimalist approach, showing only what is necessary, which gives you the space to focus on your code. With many IDEs, you’re bombarded with options galore, with side and bottom panels that often take up screen real-estate. Sublime Text’s interface is one of the cleanest interfaces for a code editor. You can close Sublime Text safely and know that everything will return to you intact and without any glitches. So there’s no worry about low laptop battery or panic when Windows randomly forces you to restart mid-way through your work. Not only that, it opens and leaves exactly where you left off - including unsaved changes and code that may have been lost with any other editor. Unlike other IDEs that may take a bit of time to boot up and maybe bombard you with a few welcome messages and multi-tabs of text about the editor each time you boot it up, Sublime Text just opens. It only takes three words to sum up the awesomeness of Sublime Text for Python and they are speed, interface, and customization. You might even say that Sublime Text is the best code editor to understand Python because it is part Python.īut why, exactly, should you use Sublime Text for Python development? Why use Sublime Text for Python development? ![]() Why? Because it’s written in C++ and Python. It is great for new and seasoned developers alike, with features like multi-tab select, git integration, key bindings, file patterns, and a native command-line interface to make your workflow more efficient.On top of this, visual customizability allows the developer to create, import, and edit Sublime’s interface themes and color schemes.īy default, you can use it for any programming language - but its Python support is considered one of the best. Sublime Text Editor has been around since 2008 and has remained one of the most intuitive, free, and feature-packed code editors on the market. ![]() CMOS uses complementary (both n-channel and p-channel) MOSFET devices to achieve a high speed with low power dissipation." To reduce power consumption still further, most contemporary chip implementations of digital systems now use CMOS logic. As integrated circuits became more complex, bipolar transistors were replaced with smaller field-effect transistors (MOSFETs) see PMOS and NMOS. Transistor-transistor logic (TTL) then supplanted DTL. For higher speed and better density, the resistors used in RTL were replaced by diodes resulting in diode-transistor logic (DTL). RTL gates were used in early integrated circuits. Unlike simple diode logic gates (which do not have a gain element), RTL gates can be cascaded indefinitely to produce more complex logic functions. The simplest family of logic gates using bipolar transistors is called resistor-transistor logic (RTL). "To build a functionally complete logic system, relays, valves (vacuum tubes), or transistors can be used. The vector stencils library "Logic gate diagram" contains 17 element symbols for drawing the logic gate diagrams. The shapes example "Design elements - Transistors" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Electrical Engineering solution from the Engineering area of ConceptDraw Solution Park.

(1) Semiconductor material.: the metalloids germanium. The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. It is composed of semiconductor material with at least three terminals for connection to an external circuit. "A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. The WIKA pressure switch PSD-30 is available either with PNP or NPN switching output.The vector stencils library "Transistors" contains 30 symbols of transistors drawing electronic schematics and circuit diagrams. In contrast, in North America, the country where the transistor was invented, relay outputs with potential-free contacts for AC 110 V loads are most widely used. In my experience, PNP switching outputs are used mainly in Europe, and NPN outputs almost exclusively in Asia. When a change in signal takes place by reaching a pressure value, the supply voltage (U+) is “switched on”, allowing current to flow from U+ through the load via the transistor and to GND. The load is connected to the switching output with U+ as the reference point. When a change in signal takes place by reaching a pressure value, the supply voltage (U+) is “switched through”, allowing current to flow from U+ through the transistor and through the load to GND. The load is connected to the switching output with GND as the reference point. This is why the load must be connected differently to the transistor outputs. In principle, both are bipolar transistors in which only the internal arrangement of the pn transitions differs. Here is a brief explanation how the two different outputs should be connected. Manufacturers of electronic pressure switches often offer both PNP and NPN switching outputs. |
