When you’re shopping for your compressor, you’ll also want to keep in mind the horsepower of the unit. That’s why a lot of the products on my list are oil-free. Besides that, they also require less maintenance, so they’re great for home use. Overall, oil-free models are typically much smaller and more portable than oil compressors. If the temperature where you live is below 34 degrees Fahrenheit or below freezing, you should choose an SAE 20 weight oil. Air compressor oils are often synthetic products that don’t have any of the detergents that go into motor oil.įor the purposes of lubricating compressor motors, you’ll also want to stick to a 30 or 20 weight oil, depending on the conditions. So what’s the difference between those two types of motors?īasically, if you choose a compressor that uses oil, you’re going to need to change it - usually on an annual basis. While most of the compressors on my list are oil-free, plenty of the ones on the market still use oil. When it comes to motors, the one thing you need to remember to check is whether the unit you’re looking at requires oil or not. If you’re like me, and you like to know exactly how all of your gadgets work, you can check out this YouTube video. As the vanes spin the air that enters on one end, the chambers get smaller, expelling hot, pressurized air on the other end. Those compress the air by spinning adjustable rotary vanes that are positioned slightly off-center inside of a cylindrical motor. On the other hand, if you were looking to avoid piston vibrations, you could also purchase a rotary compressor. However, single-piston systems are still the most common ones for at-home use. Systems that operate on two or more pistons can avoid overheating while achieving an output pressure of 175 PSI. In addition to the single-piston compressors, which have an output pressure of about 50–75 PSI, there are multi-stage compressors as well. After all, the piston connects to a crankshaft, so both of those parts produce significant up-and-down and side-to-side movements. That means they are powered by a piston system, which actually isn’t the quietest option. Most of the air compressors we’ll be looking at are reciprocating compressors. Now, I should say that not all air compressors are made equal when it comes to noise levels. However, there are some other features that might help you determine the amount of noise you’ll be getting. In this case, most of the products we’ll be discussing do have reliable noise estimates. Still, not all of the products I’ve reviewed have a decibel noise estimate, so I do sometimes rely on videos and measurements from other users as well. When I’m looking for quiet machines, my favorite products are the ones that have a noise estimate in their official descriptions. As always, I’m now going to point out some of the most important features you’ll want to think about before you pick your air compressor. Some of it doesn’t really matter in the long run, but some of the specs you’ll see in my reviews can really make or break your future projects. If this is the first time you’re learning about air compressors, you’re probably confused about the terminology.

Not compatible with #93648 Off-Axis Guider, not compatible with #93519 2" Mirror Diagonal (discontinued)Ĭurrently not compatible due to mechanical interferences Use them on your dew shield or anywhere else you like!Ĭheck out the 6” Dew Heater ring and the Smart DewHeater and Power Controllers to optimize your setup for the ideal dew-free night of observing and imaging. When purchasing this item, you will receive 2x adhesive Celestron logo labels. Also, there are cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration. This slot gives you an easy way to corral essential cables (like the ones for our Dew Heater rings) without potentially allowing light pollution to leak in. Simplify and streamline your setup with the Aluminum Dew Shield’s integrated cable management slot at the base. If you’re an astroimager who enjoys using your Schmidt-Cassegrain in the Fastar/Hyperstar configuration, you’re probably used to running cables out the front of the dew shield. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging. When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. We’ve also constructed the cover cap from durable yet lightweight aluminum. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit. Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast when viewing and imaging. The exterior of the dew shield is a rigid, aluminum cylinder that will not fold, flex, or deform. The Aluminum Dew Shield provides a perfect, custom fit for 6” Celestron telescope tubes. Use the Aluminum Dew Shield on your 6” Schmidt Cassegrain telescope tube confidently, knowing it was created for your exact instrument. The Aluminum Dew Shield also increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, keeping the lens below the dew point longer and preventing dew from forming on the lens. It’s an essential accessory that protects the tube in the field. Unique data from the Glory mission, along with NASA's fleet of Earth-observing satellites will help researchers investigate the intricacies of Earth's changing climate.Th is Aluminum Dew Shield with Cover Cap fits all 6” Celestron Schmidt-Cassegrain telescope tubes. The APS will provide a global dataset of aerosol distribution with unprecedented accuracy and specificity. The Aerosol Polarimitry Sensor, or APS, is among a suite of instruments on-board NASA's upcoming Glory mission. Narrator: New tools will soon help scientists study aerosols. Mischenko: We need to study the distribution of particles globally and the only way to do that is from satellites. Researchers are still working to understand the role of these curious particles. The suppression of clouds leads to further warming of the atmosphere, by solar radiation. When aerosols heat the atmosphere, they create an environment where clouds can't thrive. And others absorb radiation which warms the air. Some aerosol particles primarily reflect solar radiation and cool the atmosphere. Aerosol-rich clouds become bigger, brighter, and longer lasting.Īerosols impact clouds in other ways. Narrator: Clouds play an important role in regulating Earth's climate. Mischenko: The more aerosol particles we have in the atmosphere, the more cloud droplets we can have. Narrator: The introduction of too many aerosols wil modify a cloud's natural properties. Michael Mischenko, Glory Project Scientist, GISS: An aerosol particle can serve as a cloud condensation nucleus. Without aerosols, clouds could not exist. In just a short expanse of time, particles can change their size and composition and even travel across vast oceans.Īerosols are difficult to study and one important new area of research involves how these particles impact clouds. But they can also originate from human activity.Īerosols are short-lived but have an active lifetime. Sometimes aerosols occur naturally from things like volcanoes. Just like people, every particle is unique. Narrator: Aerosols are suspended throughout Earth's atmosphere and the tiny varied particles play a mysterious role in human-induced climate change. A key performance metric in dynamic networks is the connection blocking probability, and therefore a dynamic optical network infrastructure must be designed to meet stringent blocking requirements (e.g., <10−3 blocking probability). Rough estimates indicate that in dynamic optical networks, transponders will comprise a significant component (e.g., 60%–70%) of the cost of the optical networking infrastructure. In order for dynamic optical networks to be commercially viable, it will be essential to have signaling protocols that can establish connections quickly and minimize the use of transponders for wavelength conversion and regeneration. Whereas the second finer approach does imply an increase of algorithm complexity, higher control overhead and slightly lower scalability, it will be shown that it significantly reduces the blocking probability while maintaining an excellent restoration overbuild usage. The experimental performance evaluation and comparison of the two schemes is conducted with regard to two figures of merit: connection blocking probability and restoration overbuild. A detailed description of the two algorithms, along with the required extensions to current GMPLS routing protocols are provided. The second approach relies on full network state information leading to both increase backup sharing based on enhanced link channel information, and reduce connection blocking due to WCC. The first approach relies on partial network state information that aims at increasing backup sharing based on aggregated link bandwidth. The novelty of this work, from the best of our knowledge, is twofold: presenting and evaluating two routing approaches that besides maximizing resource usage address connection blocking caused by the WCC, and that both schemes are experimentally implemented within a real GMPLS-based network using ADRENALINE testbed. In this scenario, both working and backup lightpaths use a single wavelength for all links in their respective paths (i.e., wavelength continuity constraint, WCC). This article focuses on the problem of dynamic and distributed shared path protection (SPP) in all-optical GMPLS networks without wavelength conversion capability. These options may be your best bet.īecause you are planning to use Joomla as your CMS, I highly recommend seeking out specialized Joomla hosting.

Making the move to selling products and services online – often called eCommerce – is a major step forward for your personal business. Office as a one-time purchase does not include any of the services included in Microsoft 365. Office 2010 and Office 2007 are compatible with Windows 8.1 and earlier. Previous versions include Office 2016,Office 2013, Office 2011 for Mac,Office 2010,Office 2007, Office 2008 for Mac, and Office 2004 for Mac.Classic versions of the office apps installed on 1 Mac or PC. The essentials for individuals to get it all done. Includes the latest AI-powered Office apps, 1 TB of cloud storage, and premium mobile features. Choose the right Microsoft 365 subscription for your Mac.For example, Microsoft made the following Mac versions of Office: Office 2011, Office 2016 and they released Office 2019 in September 2018. Microsoft 365 subscribers get access to new versions of Office when they are released, which is typically about every 3 or 4 years. Frankly, I don’t believe I’ve ever used them so I can’t comment on how similar or dissimilar they are from the full desktop versions. The online versions are cleverly named Word Online, Excel Online, etc. Microsoft offers a web-based version of these applications.The online versions are only available if you have an Microsoft 365 subscription. It is important to know that regardless of whether you buy Office as a stand-alone product or as part of Microsoft 365, you get the ability to download and install Word, Excel, PowerPoint, etc on your Mac. I’d like to point out a few other considerations that I think you should keep in mind as you make your decision. Whether you have Office 2016 or even another office suite (as we'll discuss below), you can still do what you need to do: create and edit documents, spreadsheets, and presentations.Are you trying to decide if you should buy Office for Mac as part of a Microsoft 365 subscription or as a stand-alone product? While cost is one important consideration it is not the only one. Unless you're an Office expert, you won't use most of the new tools anyway. If you have Office 2016, Office 2019 isn't a must-have upgrade. However, it means that your purchase has less value, as you'll need to upgrade sooner to avoid using an unsupported version of Office. Microsoft is likely doing this to reduce the amount of old software it has to support. This is quite a drop from the five years of extended support that previous Office editions offered. Office 2019 will enjoy five years of mainstream support (ending on October 10, 2023), but only two years of extended support after that (ending on October 14, 2025). However, Microsoft has changed its support plan with Office 2019 to reduce this period. The Microsoft 365 Family plan costs $9.99 per month (or $99.99 per year) and allows up to six total people in your family to use Office across every platform they use.Īs we've discussed, the biggest advantage of buying Office 2019 is that you can use it as long as you want without additional cost. Microsoft 365 Personal costs $6.99 per month (or $69.99 per year) and lets one person use Office on all their devices.

Meanwhile, Microsoft 365 includes all these apps in each plan. However, this doesn't make much sense when you can get Home & Student for just $10 more. Instead of these packages, you can also buy individual apps (such as Word or Excel) for $139.99 each.

A few days after this post a comment was added that a version of Office for M1 Macs was also released.
The cross sections for the qq H H, V H H, and t t ¯ H H process are more than one order of magnitude smaller . Both diagrams depend on the coupling of the H boson to the top quark, denoted by the symbol y t, which is measured with an uncertainty of order 10% at present . The diagram that provides the sensitivity to λ is the “triangle” diagram shown on the left. The right diagram, referred to as the “box” diagram, does actually not depend on the trilinear H boson self-coupling λ. The leading order (LO) Feynman diagrams for the two competing production mechanisms are shown in Fig. 1. The cross section is rather small, as the production of H boson pairs through gluon fusion is a loop induced process, and is further reduced by the negative interference of two competing production mechanisms. 40 fb at s = 13 TeV center-of-mass energy . Including corrections for finite top quark mass effects, computed at next-to-leading order (NLO), the SM cross section for the g g H H process amounts to 31. Its cross section has been computed at next-to-next-to-leading order (NNLO) in perturbative quantum chromodynamics (pQCD), with resummation of soft gluon contributions at next-to-next-to-leading logarithmic accuracy. The total H H production rate is dominated by the g g H H process. In analogy to the production of single H bosons, four different processes are relevant for H H production at the LHC: gluon fusion ( g g H H), vector boson fusion ( qq H H), the associated production with a W or Z boson ( V H H), and associated production of the H boson pair with a pair of top quarks ( t t ¯ H H). The trilinear coupling ( λ) can be determined at the LHC, by measuring the rate for H boson pair production ( H H). The measurement of the quartic coupling is not possible at the LHC , even with the 3000 fb −1 of data foreseen to be recorded at s = 14 TeV center-of-mass energy during the upcoming HL-LHC data-taking period , as the cross section of the corresponding process, triple H boson production, is much too small, on the level of 5 ⋅ 1 0 − 2 fb . Measurements of the H boson self-interactions will allow to determine the potential of the Higgs field, thereby ultimately either confirming or falsifying that the Brout–Englert–Higgs mechanism of the SM is responsible for EWSB. The SM predicts H boson self-interactions via trilinear and quartic couplings. Evidence for its coupling to up-type fermions, at a strength compatible with the SM expectation, has been observed recently . So far, all measured properties of the discovered particle are consistent with the expectation for a SM H boson within the uncertainties of these measurements. The predictions have been probed by measurements of its spin and CP quantum numbers ,, ,, of its couplings to gauge bosons and to down-type fermions , and of its total decay width, including decays to invisible particles ,. The Standard Model (SM) of particle physics makes precise predictions for all properties of the H boson, given its mass. Recent analyses of data collected during LHC Run 2 corroborate this value . In a combined analysis of the data recorded by ATLAS and CMS during LHC Run 1, the mass of the H boson has been measured to be 125. The discovery of a Higgs ( H) boson by the ATLAS and CMS experiments , represents a major step towards our understanding of electroweak symmetry breaking (EWSB), as well as of the mechanism that generates the masses of quarks and leptons, the particles that constitute the “ ordinary” matter in our universe. If that’s too weird for you, all the favorites are made with uncommon nuance here e.g., the exceptionally tender rice noodle roll with barbecued pork. The carts have stuff you can’t find elsewhere, like bouncy, noodlelike strips of jellyfish in a chili oil dressing. “The midsize room has fluorescent lighting, a modicum of Chinese decor, and families and friends piling lazy Susans with startling amounts of food.

Time will tell if this upstart retains its title.īack in the central International District, Harbor City Restaurant and Jade Garden turn out solid dim sum with the long lines, crowds and clatter that you’ll find in other cities. Online reviewers note that very acceptable, if not great, dim sum can be found in almost every corner of the region, with quality peaking as new restaurants open and then declining over time without the demands of a really concentrated Chinese community in any one locality to create competition.Īgainst this backdrop, the newcomer Foo Lam Chinese Restaurant takes the current prize as Seattle’s best dim sum restaurant, both for its high quality renditions of the classics and its willingness to put more adventurous dishes on the menu. With the Chinese community spread across communities in Seattle, Bellevue and Redmond, the area’s dim sum scene is characterized by its breadth. » Read more: Our Ultimate Dim Sum Menu Guide with Pictures and Translations Today, this original Chinatown adjacent to downtown has evolved into the pan-Asian International District, while the Chinese community has scattered throughout the greater Seattle metropolitan area. Subject to violent discrimination during the 1880s, the local Chinese community only firmly took root around King Street in the early 1900s. It would be a mistake, however, to dismiss the Emerald City entirely in favor of its Canadian neighbor, as several above average dim sum options exist across the Seattle area for those who don’t wish to journey north of the American border.Ĭhinese immigrants first came to Seattle in the 1850s, when jobs in mining and fishing drew laborers to the Pacific Northwest. The best dim sum in Seattle, the old joke goes, is found 150 miles north in Vancouver. If you want to take your focus stacking to the next level by adding a touch screen interface or two additional axis' of automated motion (subject rotation for example) check out the latest version of StackShot - the StackShot 3X, we also have a comparison of the two controllers. This is where StackShot comes in, it is an automated focusing rail for repeatably collecting images for focus stacking. Additionally, sub-millimeter steps are difficult at best. There is a lack of accuracy, reproducibility, speed, and precision. Unfortunately there are several drawbacks. These macro rails allow the distance to be adjusted and provide a crude manual method for taking the series of shots required for focus stacking. Most macro photographers are familiar with using a macro rail to adjust the camera’s position relative to the subject of interest. Ideally each of these images is taken at a fixed distance interval. The images are usually collected with a macro rail and combined using a software program such as Zerene Stacker or Helicon Focus. Focus stacking is the art of digitally combining a series of images with a narrow depth of field into a single image with an extended depth. How do photographers capture that stunning shot at high magnification and still have great depth of field? Enter focus stacking. Unfortunately macro photographs often suffer from a narrow depth of field. It brings to life detail that the human eye all too often misses.
