After the drive defrag has been completed, you will get a notification for the same.Once the first one gets defragmented successfully, the other one will start automatically. There are two tabs on the top (Windows & Data) that indicate different drives we have selected for defragmentation. As you can see in the above picture, the defragmentation process has been started.After deciding on everything, you need to tap on Smart Defrag & IObit Smart Defrag will start the defragmentation process.You can also hover the cursor onto the down arrow section on any of the drives to see more options ( Auto Defrag, Boot time defrag, & Disk Cleanup).Just as shown in the above picture, you need to start the defragmentation process by selecting the drives you wish to defrag (we are going ahead with both the drives).All you need to do is, just select the drive you need to defrag & once the decision is made, tap on Start Defrag. Though the page doesn’t have much info to hold, it holds the info about how to go with defragging your system drives. The Disk Defrag section is the same page we have landed on as soon as IObit Smart Defrag launched on the system. So let’s start going through each section of IObit Smart Defrag software to understand it fully (one by one):Īlso Read: How Safe is to Recover Deleted Files in Windows 10 Hard Drive? 1.

This is when we start making mistakes by jumping onto the first cleanup software we see in front of us. Now that it’s been established that you are in dire need of disk cleanup software more than ever. Which Disk Cleanup Software One Must Choose? However, if the fragmentation level goes up, you need to turn yourself to disk cleanup software available in the market. You need to make sure that the fragmentation level is as less as possible so that the system performance doesn’t get affected. Though disk fragmentation is all about using the space (available) on storage devices, it needs to be on the minimum level. The more disk fragmentation will spread, your PC will start working slower than ever before. And due to this constant change in the overall filing, fragmentation is quite natural. Since we are continuously working on those files, they are being edited in different forms like writing & resizing. Disk fragmentation simply means that your files are being broken into pieces on various parts of the disk. Times when you are installing new applications or deleting large amounts of files, disk fragmentation has started already.

Which released in 2008, the team at RGG studio's liked to do spin-off titles to experiment with new technologies before integrating them into the main series. Yesterday at the PlayStation State of Play, we got a glimpse at Like A Dragon: Ishin! A remake of the 2014 spin-off that had never seen an official western release. But here is everything you've missed from the RGG Summit! Like A Dragon: Ishin! Not only are there 3 new titles to look forward to, but there is also the release of the Judgement spin-off series for the PC. Now in the west, the series had shed the name Yakuza and marches into the new generation under the same name as the Japanese release: Like A Dragon. He left the director spot to Masayoshi Yokoyama who had produced and written these titles since their inception. And what was first a small series with a dedicated fanbase has now blossomed into a full-on global phenomenon. After 30 years with the company, the series director and producer Toshihiro Nagoshi who initially pitched the series as a last-ditch effort to Sega in the 2000s left the company. Yakuza 7: Like a Dragon, released here in the west, was very much the end of an era for Sega's hit franchise. Here is everything you need to know about Like a Dragon moving forward! The Ryu Ga Gotoku Summit was everything we wanted and then some.

But perhaps one of our favorite attributes is just how quiet this microwave is. It also has a unique AccuPop Cycle that uses sound sensors to track the time between pops of popcorn to help prevent popcorn from burning - no hovering required. The microwave has the same special scan-to-cook technology as LG's model, which allows you to scan the barcode of frozen items and send cooking instructions directly to the microwave. It's a feature that's especially helpful when using the appliance to prepare meals that take longer to cook, especially since you can even use voice commands via Google Assistant or an Alexa-enabled device when your hands are tied with other prep tasks. Use the compatible Whirlpool app on your phone or tablet to operate the microwave from afar - you can start it, monitor cooking and even adjust settings all over Wi-Fi. We recommend reviewing the instruction manual before operating for best results.ĭespite that it's much more reasonably-priced than our top overall pick, this over-the-range microwave has similar smart functionality. Just note: Since there are so many accessories and features, including 20 presets, there's a bit of a learning curve to really take advantage of all this microwave has to offer. It's no surprise this model and its inverter technology - technology that continuously delivers power - won a Kitchen Gear Award. The chicken wings were exceptionally crispy and we couldn't believe how evenly the convection oven baked a nine-inch yellow cake. We tested both and were pleased with the results. Sure, it can perform simple tasks like popping a bag of popcorn or reheating soup, but it can also take on more complicated cooking tasks with its convection abilities, like air frying chicken wings and even baking a cake. The Panasonic microwave is also a broiler, convection oven and air fryer, hence the four-in-one in its name. The HomeChef 4-in-1 Microwave Oven is as versatile as they come - and not just because it can be installed as a built-in or set on a countertop. You can find out more and download a free copy of TopNotch here. Top Notch From MakeTheWeb, makers of the CleanShot screen capture app, Top Notch (free) can be set to launch at startup and it appears as a menu bar icon. There's support for spaces, multiple displays and rounded wallpaper corners, but this is just a simple tool - one that gets the job done, however. Click on Applications in the Finder sidebar and locate the app you wish to scale and adjust to the notch. Rather than taking the approach of some Android apps and transforming a camera notch into something useful like a battery meter, TopNotch makes the menu bar black so you just don't notice the notch. It’s not a recently launched app, but rather it’s an old version of notch application that offers a transparent menu bar on macOS. Unlike the other application, it offers the same features just like a form of a drop-down menu right in the menu bar. It's a similar idea to other apps designed for iPhone, disguising the notch so it is practically invisible. De-Notch-Ifier: Best Paid App to Hide MacBook Pro Top Notch. One such option is TopNotch, a free tool that, to quote the developers, "makes the notch disappear like a ninja". Sadly, this is not an option that Apple saw fit to build into macOS, so you'll have to look to third-party solutions instead. But if you find the black wedge to be something of a distraction, you can make its appearance far more subtle and effectively hide it from view. Notch Remover lets you hide the notch in the status bar Notch Remover modifies your wallpaper to adjust for the notch. Interestingly, ezTalks also offers top-notch. It is, of course, not possible to remove the notch as it is a physical component. ezTalks is another web-based Zoom Meeting for Mac alternative to host meetings, video conferences, and webinars.

With 4 tetrahedrals, the shape of the molecule looks like this. This is due to the electrons that are shared are more likely to repel each other. Now, what are we going to do with 4 tetrahedrals? Well, we want to optimize the bond angle of each central atom attached to each other. Remember that electron groups include lone pairs! Butane doesn't have any lone pairs. We aren't done, yet! We need to determine if there are any lone pairs because we only looked at bonds. By breaking the molecule into 4 parts (each part looks at 1 of the 4 Carbons), we determine how many electron groups there are and find out the shapes. In this case, we have 4 central atoms, all Carbon. We did this by lookin at a particular central atom. We took a look at butane provided by the wonderful wikipedia link. As for the rightmost Carbon, we also have a tetrahedral where Carbon binds with one Carbon and 3 Hydrogens. Continuing this trend, we have another tetrahedral with single bonds attached to Hydrogen and Carbon atoms. Again, we have 4 electron groups which result in a tetrahedral. This Carbon has 2 single bonds to 2 Carbons and 2 single bonds to 2 Hydrogens. By checking the geometry of molecules chart above, we have a tetrahedral shape. That means that we have 4 electron groups. We see that C has three single bonds to 2 Hydrogens and one single bond to Carbon. If we break down each Carbon, the central atoms, into pieces, we can determine the relative shape of each section. You can view a better structural formula of butane at C-C-C-C is the simplified structural formula where the Hydrogens (not shown) are implied to have single bonds to Carbon. Follow the example provided below:īutane is C 4H 10. In other words, we take long chain molecules and break it down into pieces. For the final description, we combine the separate description of each atom. We take in account the geometric distribution of the terminal atoms around each central atom. The VSEPR theory not only applies to one central atom, but it applies to molecules with more than one central atom. Molecules with More than One Central Atom Geometry of Molecules Chart Number of Electron Groups For example, a molecule with two bond pairs and two lone pairs would have this notation: AX 2E 2. The x represents the number of lone pairs present in the molecule. When lone pairs are present, the letter E x is added. "A" represents the central atom and n represents the number of bonds with the central atom. The VSEPR notation for these molecules are AX n. See the chart below for more information on how they are named depending on the number of lone pairs the molecule has.Īs stated above, molecular geometry and electron-group geometry are the same when there are no lone pairs. When the electron groups are all bond pairs, they are named exactly like the electron-group geometry. Molecular geometry, on the other hand, depends on not only on the number of electron groups, but also on the number of lone pairs. We separate this into two categories, the electron-group geometry and the molecular geometry.Įlectron-group geometry is determined by the number of electron groups. Although VSEPR theory predicts the distribution of the electrons, we have to take in consideration of the actual determinant of the molecular shape. Thus, the molecule's shape reflects its equilibrium state in which it has the lowest possible energy in the system. The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction. The shape of a molecule is determined by the location of the nuclei and its electrons. Using the VSEPR theory, the electron bond pairs and lone pairs on the center atom will help us predict the shape of a molecule. An electron group can be an electron pair, a lone pair, a single unpaired electron, a double bond or a triple bond on the center atom. VSEPR focuses not only on electron pairs, but it also focus on electron groups as a whole. Thus, electron pairs will spread themselves as far from each other as possible to minimize repulsion. The valence-shell electron-pair repulsion (VSEPR) theory states that electron pairs repel each other whether or not they are in bond pairs or in lone pairs. Now that we have a background in the Lewis electron dot structure we can use it to locate the the valence electrons of the center atom. Valence-Shell Electron-Pair Repulsion Theory Therefore, the Fourier transform of the correlation function of transition dipole moment is directly proportional to the vibrational spectra.\) Is it true that one can calculate the vibrational spectrum of a bond by the Fourier transform of the dipole moment vector autocorrelation function $C_(t)$. Two additional DLMs are currently available outside the United States: FineDuo (Terumo Europe) and the Crusade (Kaneka Medical Products). There are currently five DLMs available in the United States and FDA approved for coronary use: Twinpass and Twinpass Torque (Teleflex), NHancer Rx (IMDS), Sasuke (Asahi Intecc USA, Inc.), and ReCross (IMDS). In this scenario, the subintimal wire (through the rapid-exchange port) acts as a guide and provides support to the second working wire (through the over the wire port) that can be manipulated to find the true lumen. DLMs may be helpful when a parallel wire technique is needed during antegrade CTO PCI. 6 DLMs have several useful applications when employed in the context of CTO PCI ( Table 1). 5 The presence of bifurcation lesions in the context of CTO, which occurs occasionally, increases the complexity of these lesions greatly. The technical success of CTO PCI has improved recently due to the development of novel techniques and devices, 1,5 however, the inability to cross the CTO remains the most common cause of failure. Chronic Total OcclusionsĬTOs still represent one of the most challenging lesion subsets for percutaneous intervention. DLMs can also provide additional support when rewiring difficult side branches through prior stent struts. This technique was first developed by Kawasaki et al in 2008, 4 but it has been modified to incorporate DLMs to facilitate wiring of narrow, angulated side branches. In this instance, a microcatheter-assisted reverse wire (RW) technique can be employed to facilitate wiring of the side branch. DLMs can be particularly helpful in challenging side branch wiring due to highly angulated (angles ≥ 150°) side branches, or those with unfavorable take-off angles when conventional wiring techniques have failed. 3 It remains one of the most challenging subsets of lesions, often due to difficulty in wiring of the side branch. Their application is most useful in the setting of PCI for bifurcation lesions, CTOs, and a combination of the two ( Table 1).Ĭoronary bifurcation PCI accounts for approximately 20% of all PCI procedures and is associated with increased procedural cost, higher complication rates, and worse outcomes. The role for DLMs is expanding and will likely continue to grow with the increase in complexity of PCI. Martins Filho from this issue for additional reading. 2 This article focuses on the currently available DLMs and their applications. However, all share the common feature of two distinct lumens to facilitate the precise handling of two separate guidewires. Each device has unique design characteristics. Several DLMs are currently available and the role for their utilization is expanding. 1 Dual lumen microcatheters (DLMs) have recently been introduced to further facilitate PCI of complex anatomy. The use of novel techniques and devices, such as microcatheters, has become essential in increasing the success rate of these more complex interventions. Additionally, there has been an uptake in the treatment of chronic total occlusions (CTOs), which pose a particular challenge for percutaneous revascularization as opposed to bypass. Patients undergoing PCI are older, have more comorbidities, prior coronary bypass grafts, and more heavily calcified and tortuous lesions that often involve coronary bifurcations. The complexity of percutaneous coronary intervention (PCI) in the current era has increased significantly. The higher the lumens value of a lighting device, the greater the area it illuminates. Lumens refers to the total amount of light a lighting apparatus emits. However, they may not be relevant for your needs. Some may try to convince you about the merits of a lighting device by quoting impressive lumens or candela numbers. More importantly, this knowledge will ensure that your lighting supplier does not cheat you. Knowing about the difference between lumens and candelas will help you choose lighting devices that are ideal for your workplace. Lumens and candela are both lighting measurement units, but they measure different aspects of a lighting device. Lumens = candela × ( 2π(1 - cos(degrees/2)) ) Times 2 times pi times 1 minus cosine of half the apex angle θ in degrees (°): The luminous flux Φ v in lumens (lm) is equal to the luminous intensity I v in candela (cd), The solid angle Ω in steradians (sr) is equal to 2 times pi times 1 minus cosine of half the cone apex angle θ in degrees (°): Times the solid angle Ω in steradians (sr): In lumens (lm) is equal to the luminous intensity I v in candela (cd), And lamps will often display a lux value for a set distance to give you an idea of how bright your surface will be for task lighting.įor uniform, isotropic light source, the luminous flux Φ v Light bulbs are usually listed in lumens to show how much illumination the uncovered bulb produces. A laser pointer will have an extremely low lumen value but a very high candela rating, since a laser pointer doesn’t give off very much light but is visible from great distances. So why all of the different ratings? Since candelas, lux, and lumens are all measuring something different, you can gain insight into how a lamp is useful. This is because lumens measure the total amount of visible light from a light source. Obscuring half the bulb (making it a hemisphere instead of a full sphere), a 1 cd bulb will emit only 6.28 lm. For a bulb emitting 1 cd, that bulb would also have a luminous intensity of 12.57 lm. To show the difference between lumens and candela, let’s go back to the example previously used for candela with the partially obscured light bulb. To put it simply, the lumen rating is how much total visible light is produced by a light source. The lumen (lm) is a measurement of luminous flux, or the total amount of visible light. Lumens are now the most common measurement for a light bulb. To get the luminous intensity in candela: Enter Luminous intensity in candela: Candela to lumens calculatorĮnter the luminous flux in lumens, apex angle in degrees and press the Calculate button Candela (cd) to lumens (lm) calculator and how to calculate. |
