9/9/2023 0 Comments Hydrogen atom modelIn the early 20th century, experiments by Ernest Rutherford established that atoms consisted of a diffuse cloud of negatively charged electrons surrounding a small, dense, positively charged nucleus. The quantum theory of the period between Planck's discovery of the quantum (1900) and the advent of a mature quantum mechanics (1925) is often referred to as the old quantum theory.īohr model in 1921 after Sommerfeld expansion of 1913 model showing maximum electrons per shell with shells labeled in X-ray notation A related quantum model was proposed by Arthur Erich Haas in 1910 but was rejected until the 1911 Solvay Congress where it was thoroughly discussed. However, because of its simplicity, and its correct results for selected systems (see below for application), the Bohr model is still commonly taught to introduce students to quantum mechanics or energy level diagrams before moving on to the more accurate, but more complex, valence shell atom. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics and thus may be considered to be an obsolete scientific theory. The Bohr model is a relatively primitive model of the hydrogen atom, compared to the valence shell model. Not only did the Bohr model explain the reasons for the structure of the Rydberg formula, it also provided a justification for the fundamental physical constants that make up the formula's empirical results. While the Rydberg formula had been known experimentally, it did not gain a theoretical basis until the Bohr model was introduced. The model's key success lay in explaining the Rydberg formula for hydrogen's spectral emission lines. The improvement over the 1911 Rutherford model mainly concerned the new quantum mechanical interpretation introduced by Haas and Nicholson, but forsaking any attempt to explain radiation according to classical physics. ![]() In the history of atomic physics, it followed, and ultimately replaced, several earlier models, including Joseph Larmor's solar system model (1897), Jean Perrin's model (1901), the cubical model (1902), Hantaro Nagaoka's Saturnian model (1904), the plum pudding model (1904), Arthur Haas's quantum model (1910), the Rutherford model (1911), and John William Nicholson's nuclear quantum model (1912). It is analogous to the structure of the Solar System, but with attraction provided by electrostatic force rather than gravity. In atomic physics, the Bohr model or Rutherford–Bohr model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913, consists of a small, dense nucleus surrounded by orbiting electrons. ![]() The 3 → 2 transition depicted here produces the first line of the Balmer series, and for hydrogen ( Z = 1) it results in a photon of wavelength 656 nm (red light). ![]() The orbits in which the electron may travel are shown as grey circles their radius increases as n 2, where n is the principal quantum number. The cake model of the hydrogen atom ( Z = 1) or a hydrogen-like ion ( Z > 1), where the negatively charged electron confined to an atomic shell encircles a small, positively charged atomic nucleus and where an electron jumps between orbits, is accompanied by an emitted or absorbed amount of electromagnetic energy ( hν).

Of the two, Slack offers more customization options, with many different ways to tweak the sidebar’s look and what appears on it, such as whether to always include all direct messages, how to sort content, and so on. ![]() The Teams look and feel is well organized and efficient, with messaging front and center. Teams has a vaguely corporate look, which feels more streamlined but generic. Slack has a freeform, looser feel that we like but some might consider a tad chaotic. Look and feel: Both the Slack and Teams desktop apps have easily navigated interfaces, with messaging front and center as the focus. (Note that in this story we’re looking at Teams primarily as a work hub based on text chat, not at its videoconferencing features.) Here’s what we found. To make your decision a little easier, we’ve compared Slack and Teams for enterprises in six categories: interface and usability integrations additional noteworthy differences mobile and browser apps security, compliance, and enterprise management and pricing. In fact, some enterprises have effectively chosen not to choose. There are two excellent collaboration platforms from which to choose, both of which are constantly getting better as new features are added. Slack said its paid customer base was more than 177,000 in August 2021. For its part, Slack has said its own users are more actively engaged, interacting with Slack on average 120 minutes a day and overall taking more than five billion actions a week. ![]() Indeed, Microsoft has been touting Teams’ growing user numbers with great fanfare, citing 250 million active daily users as of July 2021. 9/9/2023 0 Comments Invisible emmie![]() Todos los enamoramientos, humillaciones, aburrimientos y pequeños grandes dramas que sufrimos a los doce años, están concentradosen un solo y sorprendente día en esta extraordinaria novela gráfica sobre la amistad, la autoestima, la empatía y el compañerismo.

Most of the time, you'll use the JPEG format for photographs. File format: Save for Web allows you to choose from a few Web-safe file formats.When you use the Save for Web feature, you'll need to make a few decisions about the image you're saving: Notice how the PSD format preserves the individual layers, while the JPEG format does not. Open the example file in Photoshop and try saving it in different file formats, like PSD and JPEG. You need to tick the box Enable legacy “Save as.” Go to Edit > Preferences > Ctrl + K > File handling > enable Legacy “Save as”> OK. Sometimes when you're saving the file, you haven't activated all of the possible formats. However, if you're working with another format like JPEG, we recommend using Save As to avoid overwriting your original file. If you've already saved your project as a PSD file, you can select File >Save or press Ctrl+S (or Command+S on a Mac) to save your progress at any time. With the image open in Photoshop, select File > Save As.You'll use the Save As command to save files in the PSD format, as well as other common formats like JPEG and PNG. As you start to gain more experience with Photoshop, this process will begin to feel quick and natural. Before saving an image, take a moment to consider the type of files you'll need. Because none of these edits are too complicated, you probably don’t need to save a separate PSD version of each image.Īs you can see, the saving option you choose will vary from project to project. In this case, you could open the original image files in Photoshop, make the necessary adjustments, then save a new version of the edited photos as JPEGs. You'd just like to make some quick adjustments in Photoshop, like cropping and rotating, before sharing them. Let’s say you're planning to share some photos from a recent vacation with your friends. And because it will eventually be posted online, you'll also want to use Save for Web to create a new JPEG version of the finished image. This way, you can easily continue editing the file later on. Because you'll likely edit and revise this type of project, you'll want to save it as a PSD file. You've been given a photo to include, and you need to add some text with the company name. Let's say you're asked to create a new header image for a company website. Let's take a look at a couple of scenarios to see why you might choose different saving options. Ultimately, the saving option you choose will depend on what you need to do with the image. You can see that the Web version has a much smaller file size than the original and PSD versions. In the image below, you can see three different versions of an image file: the original JPEG file, an edited PSD version, and a final JPEG version that's been resized and saved for the Web. Save for Web also includes several helpful features for preparing images for the Web, including the option to resize images. This tool allows you to save images that are optimized for the Web, which will make them easier to download and view online. Save for Web: If you're planning to upload an image to the Web, like on a blog or website, you'll want to use the Save for Web feature.However, unlike PSD files these formats aren't as useful if you plan to continue editing the file, and they also can't preserve layer information. These file formats can be viewed and edited on almost any computer or mobile device, which makes them well-suited for sharing with others. Common file formats: You can save images in a variety of common file types, including JPEG and PNG.PSD files are designed to be opened in Photoshop, so if you want to share the image with others you'll also need to save a copy of the image in a common file format, like JPEG. It will save your layers and all of the other information in your image so you can easily re-edit it later. PSD: This is the default file type for Photoshop documents, although you won't necessarily use it for every image.When saving a file in Photoshop, you have several options and file formats to choose from: 9/9/2023 0 Comments Jump desktop for macIt runs on macOS, Linux, and Windows 11, 10, 8, 7, and XP. The program auto-updates and can enter full-screen mode, create a balance between quality and speed of the connection, transfer files and sound, sync the clipboard, record the remote session, run keyboard shortcuts, take screenshots of the remote computer, and restart the host computer. If unattended access is set up, the client doesn't need to wait for the host to accept the connection. You can also connect to the host from AnyDesk's web client. On another computer, run AnyDesk and then enter the host's Remote Desk ID or alias in the Remote Address section of the program, and wait for the host to accept the connection. When the client connects, the host will be asked to allow or disallow the connection and can also control permissions, like to allow sound, clipboard use, and the ability to block the host's keyboard/mouse control. Launch it on the PC you want to connect to and record the 9-digit number, or custom alias if one is set up. Android users can install the client app.ĪnyDesk is a remote desktop program that you can run portably or install like a regular program. It also works through a mobile web browser. The DWAgent tool for the host can be installed on several operating systems, including Windows, Linux, and macOS. They let you create all sorts of text-based files browse through the file system to make, edit, or remove files, and upload or download files to and from the host run Command Prompt commands view basic system information, shut down tasks, and start or turn off services.

Give the code to the host during the program installation.ĭWService has a handful of tools. Make a user account through the link below (it's totally free), and then add a new agent to your account. If the host installed the program, the setup procedure is a little more involved. Log in through the link below and enter the code and password that shows on the host's DWAgent program window. The client has it easy if the host uses the on-demand option. Otherwise, enter the code and provided by the client so that they can have always-on access to the host computer. ![]() If you choose the run option instead of the install option, you're given a user code and password that the client needs to reach the computer. The host has two options: download the DWAgent, and then run it for on-demand, one-time access (great for tech support), or install it for permanent remote access (ideal if it's your own computer). The host installs or temporarily runs the program, and the client logs in via any web browser to run commands, control the screen, or control files and folders.

Agility: NoSQL databases are designed to react quickly to unexpected situations.NoSQL databases offer several advantages that make their work easier. Information is growing, and IT developers are facing bigger and bigger challenges: huge volumes of data, unpredictability, rapid evolution, and a wider range of unstructured data sources. What are the advantages of non-relational (NoSQL) databases? Today, NoSQL databases are still widely used by developers when it comes to creating complex systems (especially when working with open data). Relational models were only used to ensure that the stored information was consistent. They are widely used by digital companies such as Google and Facebook, due to their ability to manage exponentially growing volumes of unstructured data. The increasing accessibility of cloud computing and big data (particularly unstructured information) has accelerated the importance of NoSQL databases. But it wasn’t until 1998 that Carl Strozzi introduced the concept of the NoSQL database. The technology first appeared in the 1970s. They are often compared to relational (SQL) databases, which are limited to structured data. They are capable of processing large volumes of changing unstructured data. NoSQL databases are a type of database management system (DBMS). So what are they? What are their advantages ? What are they used for? What is a NoSQL database? These are difficult to store in relational databases, leading to the increasing use of NoSQL (Not only SQL) databases. However, organizations today collect and need to use increasing quantities of unstructured data, such as images, videos, PDFs and emails. Relational databases are designed to store structured data, such as customer records or financial information. 9/9/2023 0 Comments Beyond contact steamSome HUD icons now shrink to reduce visual noise.Tweaked the visuals of HUD and compass markers for improved clarity and consistency. ![]()

The Zipster Lite also feels less heavy than the original Nathan Zipster Belt, which weighs just over an ounce. The FlipBelt always felt light on, but it suddenly feels much heavier even in hand compared to the Zipster Lite. When putting the Zipster Lite against the FlipBelt, there is a clear winner when it comes to its weight. Photo: Lauren Keating How The Running Belts Compare: Design, Function, And Features So to my delight, I found that Nathan’s Zipster Lite also didn’t bounce, but that was just the start of the many pleasant surprises I uncovered during my runs while using it. This is something the FlipBelt doesn’t do, which was a major reason why so many people purchase the product. The problem with many is that they “bounce” during the run, sliding up from the hips. Worn around the waist, there is typically a slot for money, keys, a phone and sports nutrition. It allows the runner to be hands-free while storing goods. These are designed essentially to be pockets for the runner. Photo: Lauren Keatingīefore even discussing the product, it’s important to know the importance of running belts in general. ![]() These two things combined made it my gear go-to when getting in some quick miles. While being lightweight is its main selling feature, the amount of storage space is another attractive feature. Just like its name suggests, this is one ultra-light running belt that goes unnoticed throughout the run. That is until I started running with the Nathan Zipster Lite.

Generally, a lot of people consider Jedi Outcast to have the superior level and mission design, but Jedi Academy has significantly better lightsaber combat.Īlso, as one last sidenote. Resmen Kyle Katarn returns to the console with STAR WARS JEDI KNIGHT II: JEDI OUTCAST, the newest game being developed jointly by Activision and Raven Software. In Jedi Academy, you play as Kyle Katarn's student at Luke Skywalker's Jedi Academy on Yavin 4 and you go on various missions and are able to customize your loadout, force powers and character appearance. For those not in the know, this is the cheat code that activates dismemberment in 2002’s Star Wars Jedi Knight 2, the long-reigning king of simulated lightsaber combat. Jedi Academy is sort of spin-off from Jedi Outcast. Outcast starts with Kyle Katarn as a mercenary for the New Republic, but not long in the story he becomes a Jedi again. Thats the premise behind the next title in the Jedi Knight series, Jedi Outcast. Other Star Wars games might fulfil more specific fantasies better, but as an all-encompassing action adventure, Jedi Survivor is a riot. Jedi Outcast directly follows Dark Forces 2 and more importantly the Dark Forces 2 spin-off Mysteries of the Sith, in which Kyle Katarn nearly fell to the dark side and has since given up being a Jedi and using the Force. An Imperial agent, turned Rebel agent/Jedi after his father was killed by the Empire. Summary: Get two classic Star Wars games with the Star Wars Jedi Knight Collection, which includes Star Wars Jedi Knight II: Jedi Outcast and Star Wars Jedi Knight: Jedi Academy. In Jedi Outcast (like in Dark Forces 2), you continue the story of Kyle Katarn. 2008’s The Force Unleashed famously tried to one-up it in that department, with protagonist. First being Star Wars Jedi Knight: Dark Forces II. Of course, Jedi Knight was as famed for its array of Force powers as it was its lightsabers. The 2 in Outcast is because it is the second game in the Jedi Knight series. |
