![]() In the playoffs, the Bulls swept the New Jersey Nets, 3–0 in the Eastern Conference First Round, defeated the Charlotte Hornets, 4–1 in the Eastern Conference Semi-finals, despite losing Game 2 at the United Center, 78–76, and then defeated the Indiana Pacers, 4–3 in the Eastern Conference Finals en route to advance to the NBA Finals. The Bulls had the third best team defensive rating in the NBA. Despite the slow start, with the help of Scottie's return which was limited to just 44 games, the Bulls would post a 13-game winning streak between March and April, and still finish first place in the Central Division and Eastern Conference with a 62–20 record. Also in early March, the team re-signed former Bulls reserve forward Dickey Simpkins, who was previously released by the Warriors, and played in the final 21 games of the regular season. Vaughn would only play just three games with the Bulls before being waived on March 2. At midseason, the team traded Jason Caffey to the Golden State Warriors in exchange for David Vaughn. Despite the injuries, the Bulls held a 34–15 record at the All-Star break. However, three-point specialist Steve Kerr went down with a knee injury in January, and played just 50 games. Without Pippen, the Bulls started with a slow 9–7 record in November, but then would go on a 15–4 record until he returned in January. However, All-Star forward Scottie Pippen would miss the first half of the season due to an injured toe on his left foot sustained from the 1997 NBA Playoffs. During the off-season, the Bulls acquired Scott Burrell from the Golden State Warriors, and signed free agent Joe Kleine.

![]() In this respect, FreeHand’s master pages are not as flexible as those found in QuarkXPress or Adobe InDesign.įreeHand’s master pages display one interesting idiosyncrasy. When viewed as part of a child page, master page objects are locked. Objects placed on a master page cannot be modified on a child page, nor can master-page objects be used as blank placeholders for text and graphics. Changes made to a master page ripple through to all associated document pages. The Document panel and Library window in FreeHand 10 provide convenient access to master pages. ![]() And though master pages were originally intended as a desktop publishing tool, they function just as well when prototyping a Web site or storyboarding an animation. With the ability to create as many as 32,000 master pages, store them in the Library, and export them for use in other projects, FreeHand 10 can really speed up the document creation process. Any modifications made to a master page flow through to all of its children. ![]() Master pages, which should be familiar to anyone who owns a desktop publishing program, allow you to repeat design elements on any number of associated dependent document pages (referred to as child pages). FreeHand 10 builds on that functionality with master pages. One of FreeHand’s strengths is its ability to create and manipulate discrete pages within the pasteboard. If you regularly work with other Macromedia products, you’ll find that these common UI elements make FreeHand easier to learn and use. And the Bezier pen tool displays smart cursors that provide feedback about adding, deleting, and closing points on a path. For example, there are now color boxes directly on the Tools panel that allow you to select a color from a standard set of swatches. Of special note are the revamped color panels and the enhanced pen tool. The similarities with sibling programs - such as Flash, Fireworks, and Dreamweaver - include a consistent layout for the Tools panel, a menu structure that places shared commands in the same location, and standardized keyboard shortcuts. One change you’ll likely appreciate if you use other Macromedia applications: With this release, FreeHand acquires the common Macromedia user interface. The new features, which include master pages, an increased reliance on symbols, and tighter integration with Flash, combine to make FreeHand a great illustration program for high-volume production environments. If a software update can be said to have a theme, FreeHand 10 is all about improving workflow. ![]() Please bear in mind that too many items, submenus and shortcuts may slow down your system.

The existing foundation walls on the north, east and south side of the site are a part of the new structure due to the adjacency of a Metropolitan Transportation Authority underground tunnel to the lot, as well as the column layout of the tower. The caps serve as main supports for the vertical and lateral force-resisting systems. Five-foot deep reinforced concrete caps structurally connect the caissons and piles. The lengths of caissons and piles range from 90 to 110 feet below the cellar level. The foundation of 56 Leonard consists of 1,500-ton, 24-inch diameter caissons socketed in bedrock, and 180-ton end-bearing H-piles. The 56th mezzanine floor houses a liquid tuned damper to provide adequate structural damping for occupant comfort. The highest residential floor is the 55th level. The building includes three mechanical floors located at the 32 nd, 46 th, and 56 th floors, with outrigger and belt wall systems placed on the first two of those stories. The new tower has a height of 825 feet from the street level and a width of about 78 feet, which results in a daring slenderness ratio slightly above 10. The blending of traditional, present and future needs demanded not only the incorporation of forward-thinking solutions but also a complete vision of sustainable and resilient design. In other words, the design of 56 Leonard successfully combines the idea of old-fashioned home ownership with the present vernacular of luxury urban living. An innovation of this scope and relevance certainly presents an excellent answer to the desire for traditional home ownership in an urban setting that is as unique as its occupants, while reducing the footprint of a conventional horizontal community of homes. The vertical neighborhood is a new paradigm in which the penthouse is no longer the single story breaking from the typical floor plan mold. In the case of 56 Leonard, these concepts take the form of an innovative stack of individual homes suggesting the new idea of a vertical neighborhood in which each owner can choose a unique residence, albeit in the sky. Herzog & de Meuron, the architects behind this project, have been known for forward-thinking concepts throughout their careers. In fact, the residents of 56 Leonard will each live in a bright, inimitable private home reaching the sky. The resulting sensation is that of a vertical community of uniquely “stacked” homes. ![]() In 56 Leonard, for instance, each floor gives the impression of being a singular, virtually independent structure carefully placed and balanced over yet another unique structural entity forming the floor below. The current economic, cultural and social context of the real estate market in New York City requires serving a continuously changing and diverse group of buyers and investors from all over the world, which in turn has generated a very strong demand for excellence in analysis, design and construction of luxury residential buildings. ![]() The southwest corner formed by Leonard Street and Church Street in New York City is ground to the 56 Leonard project, a new and unique 57-story residential development comprising 480,000 square feet of gross area. ![]() More waterfall adventures in NC and beyond Please leave no trace and help preserve the beauty of Western NC.

Your mileage may vary, but it felt like the best over-glasses fit of any VR headset around. I wear chunky glasses, and the wide headset fits over my glasses just fine. There are ways to play standing or sitting down, too, but much like other tethered VR headsets, that heavy cable can sometimes get tangled under your feet or around your legs. The USB-C cable attached to the PSVR 2 headset is about 15 feet long, long enough for us to comfortably move around a roughly 7-by-7-foot play space, which is about what Sony recommends for full-motion VR gaming. However, the headset still feels better over my glasses than other VR headsets with the exception of the Quest Pro.Ī look at the hardware from above. Some people have reported that the headset has a limited "sweet spot" to make things look good with their eyes, and I've seen it take some adjustment to get my eye/head fit just right. It's possible that the cameras could allow some pass-through mixed reality, too, blending VR with what the cameras see onto the headset's display. The tracking should work in a similar way to other VR headsets. The headset's four tracking cameras allow movement in VR to be tracked without using a TV-connected camera bar. Eye tracking isn't common in consumer VR headsets yet, but the technology should be arriving on other mainstream headsets, and possibly Apple's as well. You can connect Sony's wireless Pulse headset, too, which sounds better.īuilt-in eye tracking promises to deliver better graphics, and possibly allow eye control and eye contact in VR games. Included earbuds are fine, but there aren't any ambient speakers like the Quest 2 has. That's a lot fewer wires than the breakout box needed for the original PSVR. The headset supports headphones with a standard headphone jack, and has one cable that tethers to the PS5 via USB-C, via a jack that seems to come out of one side of the headband. The headset also works really well for my glasses, fitting over my wide frames easily with soft rubberized sides to block out light, and the hardware feels comfortable over longer game sessions. The headset can move closer to your face, and lens distance can be adjusted for different IPD levels (interpupillary distance, or the space between eyes). An adjustable headband, similar to the PSVR's original design, means it'll tighten around the head like a visor instead of using an elastic strap to squeeze your face.

A Back, Home and Mute button are below, then two dedicated buttons for YouTube services and Netflix (thankfully not garish logos, just text). You use this to scroll through menus, fast forward and rewind, and select. You get a circular, four-way directional pad with a selection button in the center at the top. It is a tad slippery, and the buttons are easily pressed so when you sit on it it will change the channel, but Google didn’t try and reinvent the scroll wheel here and it all works very well. It has a nice substantial feel, fitting comfortably in your palm. Small, but not too small, slim, but not so thin it’ll disappear forever between the cushions. No matter which color you opt for, it's going to be a lot easier to find this pretty pastel thing in the dark, black hole of your couch. Where the color does come into play is on the minimalist matching remote. The color is a bit odd behind a TV where everything else is black and likely always will be, but it's going to be hidden so why not let the Google design team have some fun? Instead you can pick from Snow (white), Sunrise (pink), and Sky (blue). The big change is the color - no boring black here. ![]() ![]() It also connects to your TVs HDMI port with an HDMI output at the end of a short cable, and to power via a USB-C port and USB cable and plug (it has to be plugged into an outlet). The dongle resembles the regular Chromecast in shape and design, just a little more oblong and sporting a more subdued, matte plastic. Google’s fast burgeoning penchant for pastels being the notable exception. While the new Chromecast is a complete redesign of the original Chromecast on the inside, on the outside it looks remarkably similar. We’ve been using the Chromecast with Google TV for two months now and while it is definitely taking over as our cord-cutting household’s streaming stick of choice, there are some issues. It also doubles as a gaming console (for Apple Arcade), which the Chromecast doesn't for Google’s Stadia (although Google says support is coming next year). It's also a lot less expensive than the Apple TV 4K, which does boast a built-in Ethernet port and much more storage (the Chromecast only offers 8GB). It's cheaper than the Chromecast Ultra, still streams in 4K HDR10+ and offers all the Dolbys (Vision, Audio, Atmos, Digital +) on supported apps, putting it on par with the likes of Roku’s Streaming Stick Plus and Amazon’s Fire TV Stick 4K both for price and capability. ![]() Plus, it's a decent smart home controller, tooĪt £59.99, the new Chromecast is a genuine rival to the likes of the Amazon Fire TV Stick and the popular Roku devices.

The interface on Amazon’s Fire TV is frustrating to use and full of ads my husband won’t touch the Apple TV remote - its touchy trackpad and slippery style drive him nuts a regular Chromecast is a non-starter in a household with children and our default solution - an Xbox with a dedicated media remote - helped with family harmony but had no useful content search options.Įnter the Chromecast with Google TV. In the five years since I cut the cord, the perfect streaming device has been elusive. ![]() Firstly, discover the number of lone pairs that the central atom of C2H4 has.Īnother term for a lone pair is unshared pair. ![]() The three steps to find out the C2H4 molecular geometry and bond angles are:ġ. How to find out the C2H4 molecular geometry and bond angles? AX3 defines the shape of C2H4 as a Trigonal Planar with 120 degree bond angles. As the molecule does not have any lone pairs, we may ignore N. So, we got AX3 for the C2H4 molecule by the A-X-N method. ‘N’ denotes the number of lone pairs attached to the central atom, and C2H4 has no lone pair, meaning N=0. Here, the two carbon atoms are bonded, and both atoms have two hydrogen atoms attached to them. The number of atoms that have bonded with the central atom is denoted by ‘X’. Here, the central atom is represented by ‘A’. The A-X-N method can find out the C2H4 molecular geometry and bond angles. Lewis structure helps to find out C2H4 molecular geometry as Lewis diagram determines the number of lone pairs and bond pairs a molecule comprises. The bonded pair of hydrogen attached to carbon repels each other, and as a result, the figure thus formed is a trigonal planar. In the case of C2H4, each carbon in its molecule undergoes sp² hybridization, and the two hydrogens make the structure look like a two-dimensional triangular planar. Molecular structure defines the arrangement of atoms in a molecule or ion. As per VSEPR theory, C2H4 molecular geometry and electron geometry are the same, i.e. Each of the sp² carbon atoms has a trigonal planar geometry and an angle of 120o between the bonds. Here, one 2p orbital does not change, and it will help form a pi bond. C2H4 is an example of sp² hybridization, meaning one s orbital, and two p orbitals are mixed to give three sp² orbitals. It is said to be a hydrocarbon that has two carbon atoms connected to it with a double bond. The bond angles between the hydrogen atoms and the carbon atom are approximately 109.5 degrees.C2H4 is the chemical formula of a colourless and flammable gas known as Ethylene. The nonpolarity of CH4 is reflected in its tetrahedral molecular geometry, with the carbon atom located at the center of the tetrahedron and the hydrogen atoms located at the corners of the tetrahedron. The carbon and hydrogen atoms in CH4 have similar electronegativities, so they do not have a greater affinity for electrons and do not create a separation of electric charge across the molecule. Single bonds are nonpolar because the electrons are shared equally between the atoms. In CH4, the carbon atom is bonded to four hydrogen atoms via single bonds. Nonpolar molecules, on the other hand, do not have a separation of electric charge and are not attracted to magnets. ![]() Molecules with a polar bond, such as water (H2O), have a positive end and a negative end, and they are attracted to opposite ends of a charged object, such as a magnet. Polarity in a molecule refers to the separation of electric charge across the molecule. The tetrahedral molecular geometry of CH4 is important because it helps to determine the molecule’s physical and chemical properties, such as its symmetry and ability to participate in hydrogen bonding. The bond angle between each hydrogen atom and the carbon atom is approximately 109.5 degrees. In a tetrahedral molecular geometry, the central atom (in this case, carbon) is at the center of the tetrahedron, and the four bonded atoms (the hydrogen atoms) are at the corners of the tetrahedron. The four bonded pairs of electrons are arranged in a tetrahedral shape, resulting in a tetrahedral molecular geometry. In CH4, the carbon atom is bonded to four hydrogen atoms and has no lone pairs of electrons. The molecular geometry of CH4 (methane) is tetrahedral. In general, larger atoms lead to a larger bond angle because they occupy more space and repel bonded pairs of electrons less strongly. The bond angle in CH4 is also influenced by the size of the atoms in the molecule. In a molecule with a tetrahedral electron pair geometry, the four bonds are arranged in a tetrahedron, with bond angles of approximately 109.5 degrees between each bond. ![]() The bond angle in CH4 is determined by the number and distribution of the bonds and lone pairs of electrons around the central atom (in this case, carbon). The four bonded pairs of electrons are arranged in a tetrahedral shape, resulting in a tetrahedral molecular geometry and a bond angle of 109.5 degrees. Bond angles are an important factor in determining the shape and properties of a molecule. The bond angle in a molecule is the angle between two bonds that are connected to the same atom. |
