The strong ion exchange ligand groups of Capto SP ImpRes (left) and Capto Q ImpRes (right) are well established in large-scale purifications. Table 1 lists further characteristics of the media. These features, in combination with the well-established SP and Q ligands, make Capto SP ImpRes and Capto Q ImpRes an excellent choice for reliable intermediate purification and polishing in a commercial setting. Capto ImpRes media are based on a high-flow agarose base matrix with good pressure/flow properties (Fig 3) and a small bead size (approx. Capto SP ImpRes and Capto Q ImpRes extend the well-established Capto platform to include high-resolution media for late intermediate purification and polishing. The ligand of Capto SP ImpRes is a sulfonate group while the ligand of Capto Q ImpRes is a quaternary amine group (Fig 2). Key benefits of Capto SP ImpRes and Capto Q ImpRes include: High-resolution intermediate purification and polishing based on the well-established Capto platform with traditional ligands Flexible process design due to large operational window of flow rates and bed heights High-throughput purifications easy to optimize and scale up Higher manufacturing productivity enables improved process economy Security of supply and comprehensive regulatory support Chromatography media characteristics Ionic groups and base matrix Capto SP ImpRes and Capto Q ImpRes are strong cation and strong anion exchangers, respectively.

Sleeping wedge pillows can relax airways and reduce snoring Shoulder Support for Side SleepersĪs well as reducing pressure on your airway, a bed wedge can also help to support the shoulders and neck of side sleepers. ![]() Snoring is caused by air being unable to move freely through your nose and throat, so by keeping your airway unrestricted a wedge-shaped pillow helps you to sleep soundly – or soundless! Reducing pressure on your airway also has a key bonus that may benefit your partner more that you – it can reduce snoring. ![]() This works for both back sleepers and side sleepers, giving you the support you need for uninterrupted slumber. Using a wedge-shaped pillow to elevate your head at a 30° to 45° incline reduces pressure on your airway, helping you breathe more easily at night. Sleeping using standard pillows can create pressure on your airway, and for individuals with respiratory issues like sleep apnoea this can pose a real danger not only to your sleep but also your health. Wedge pillows like the Harley Bed Relaxer work to elevate your head as you sleep, which can provide a number of benefits to both your health and your ability to get 40 winks. We strive to ensure our clients get the best wedge pillows in the market to meet all their unique needs.A good night’s sleep is vital for a great morning, but conventional pillows can be a real nightmare for some. Patient Handling is focused on offering professional and highly experienced staff, great products, and incredible partners. It is due to the wedge pillows’ versatility that makes them so popular. When you ask a number of support pillow users, you will realize that everyone has their own taste and unique needs. These are among the few widespread benefits of a wedge pillow while some individuals enjoy the feel of triangle pillows, many sleepers end up choosing one for a particular health reason. For anyone suffering from this, a wedge pillow helps combat the severe effects of gravity and prevents blood from filling the lungs. ![]() Based on where the surgery was performed, it can decrease swelling and pain in the delicate joint areas. Doctors frequently recommend triangle pillows for patients who have recently undergone surgery. This is a recommended sleep posture for mothers-to-be because it offers the most effective blood flow to the uterus. Support pillows help reduce the back pain strain by sliding under your belly and supporting the growing bump when sleeping on your side. While sleeping on your back, tuck the high end this will ensure your spinal column is in a straight line, thus reducing back and neck pain. For you to ensure your spine is upright, you need to use a wedge pillow as a backrest pillow at the top of your bed. When you keep you use a wedge pillow, your head will be at the appropriate angle while sleeping because it allows gravity to maintain your airways open. Your tongue and tissues in your mouth tend to relax when you sleep therefore, they might block your throat and interfere with your airway consequently leading to snoring or more severe sleep apnea. A bed wedge or triangle pillow might aid in easing the sinus pressure thus, you will not have to sleep experiencing stuffiness due to a cold or flu. It is significant to ensure your head and shoulders are at an appropriate angle to help in draining your sinuses. ![]() Bed wedges apply gravity to facilitate the acid drain into your stomach rather than the throat. When you have reflux, stomach acid flows back to your esophagus the acid backs up, making you cough and experience a choking feeling. At Patient Handling, we provide the best brands of wedge pillows, including Better Living, Peak Care, and R&R Healthcare Equipment.Ī wedge pillow may be able to assist with numerous health and sleep problems, including: This shape plays a huge role in assisting the individual using the wedge pillow to maintain a semi-upright position while sleeping. Triangle pillows are typically designed for a standard firm foam and are usually triangular and with a sharp incline. A bed wedge is a pillow placed under a patient to assist them in positioning their body and posture when resting in the bed. ![]() Shave upwards like this until your just inside the edges of your lip line. You don't really need to apply too much force at all to get a clean shave. All of your strokes should be smooth and steady. Start by swiping up with the razor blade. I say not so for the edges of your mustache. In general, you want to shave with the grain of the hair- that is, in the direction the hair is growing. The mustache portion is a bit different from the rest of your face. This just makes the mechanics of shaving a bit easier. It's okay- I'll address that later.Īs you shave, your gonna want extend your upper lip over the top of your teeth to expose as much skin as possible. For some reason that area is just a bit more sensitive. I'm gonna warn you- shaving my upper lip has never been anything short of a little painful. You want enough to cover the base of what you have and little more. Amount is the name of the game here- too much and risk having to rake at your face, too little and razor burn starts to become an issue. This does two things: it opens up the pores on your face (which makes for a cleaner shave) and it relaxes the muscles (which helps prevent things like razor burn). Now, splash some warm water on your face (you can do just the area your going to shave, but a nice spritz of warm water just feels good on the face). If you have any whiteheads, pot them first and make sure they stop oozing before going on. If not, do your best with a pair of scissors. Trim it first with some clippers if you can. As a general rule, you don't want to go after anything longer than, say, 1/4 of an inch with a razor. Unless you really scrape at your face like it kicked your dog, you're not gonna ever bleed enough to really have to worry. ![]() Azure is the best server for virtualization and it’s from Microsoft, the makers of Windows.

One thing that is worth mentioning is that it does not get as much support as other premium virtualization software. The VirtualBox allows you to emulate Windows, macOS, Linux, and Solaris x86 platforms and they are all equally easy to install. You may be expecting it to have fewer features due to its price, but that simply isn’t the case. It’s completely free to use regardless of how many installs you need, and it supports a variety of operating systems.Īs a result, it can power an entire business for no extra cost. ![]() Oracle VM VirtualBox might be the most well-known virtualization software in the world for one simple reason. It is also important that the performance employees are getting makes them usable.Īfter all, if you’re using a program that is running slower than normal, it can cost you more time. As such, it is important to find the best virtualization software to match your needs. There are many examples of software that only work on macOS, so Windows users may need to utilize it as well. Of course, it would be wrong to assume that the opposite isn’t true as well. After all, sometimes updates can lag behind by months in some cases. In the majority of cases, this is used by macOS users to gain access to their favorite program or a more current version of that software. As a result, you can run all of the software and apps that exclusively work on that operating system.

TJĬast: Peter Weller, John Lithgow, Ellen Barkin Cliff Martinez’s seductive yet unsettling score sets the tone as we ponder the difference in this graceful, thought-provoking affair, where the never-better McElhone is heartbreaking as the woman discovering she’s not truly herself.

As writer-director-editor and cinematographer, Soderbergh does a remarkable job of echoing the original’s Soviet-era look and solemnity, yet moves the story along without compromising its intriguing musings on the knowability of self and others. ![]() It’s hard to imagine a Hollywood exec even sitting through Russian filmmaker Andrei Tarkovsky’s Solaris(1972), never mind stumping up for Steven Soderbergh’s US remake, but perhaps the presence of producer James Cameron facilitated this most introspective of space operas. TJĬast: George Clooney, Natascha McElhone, Jeremy Davies Young Lucas evidently believed in heroic individualism, fast cars and the possibility of escape, yet it’s the visualisation of an entire society shaped by universal surveillance, government-supplied sedatives and android police carrying very big sticks which rings darker and truer than the director’s subsequent, significantly more populist output. Viewed today – the only version available is Lucas and co-writer Walter Murch’s digitally spruced-up 2004 ‘Director’s Cut’ – its shaven headed-cast, chillingly benign language intoning state propaganda and oppressive widescreen palette of glacial whites make for genuinely unnerving viewing. The studio hated the result and the subsequent box-office debacle almost killed both their careers.

The best sci-fi movies deal as much with real-world issues as they do with interstellar conflict – it’s just that, in some cases, they may invent entirely new planets to discuss them. But the genre doesn’t just tell stories from long ago about galaxies far, far away. It’s hard to say if the geeks have taken over the entertainment industry or if the world at large has simply come to see the genre’s merits, but there might not be a bigger brand of movie than sci-fi around right now – in fact, it’s almost uncool not to be a fan these days.īut really, how could anyone in the third decade of the 21st century not appreciate science fiction to some degree? Sure, there are those who have an aversion to movies about alien cultures that inspire 4000-word theoretical treatises on fan forums. Dismissed for decades as the realm of nerds and shut-ins, the reputation of science fiction has undergone a dramatic makeover in recent years. ![]() If you want to experiment with your smart-home devices and lighting, you could try a smart bulb (such as from Philips Hue or LIFX), said Grant Clauser, Wirecutter’s senior editor covering the smart-home beat. ![]() If Casper’s simple tactile approach appeals to you, and you have a flexible budget, the Glow Light may be worth trying (it has a 30-night free trial). Jeff Chapin, Casper founder and product designer, told me that new moms have used it for middle-of-the-night feedings. Once you live with the Glow Light, you might discover other uses. Its lantern-like night-light came in handy the time my son yelled for me from his room at 4 a.m., as well as when he needed a lamp for his pillow fort. Later I’d move it to my living room, where I like to read before bed, and then onto my nightstand for waking me up in silence the next morning. Come dusk, I’d place it on my son’s nightstand so that 30 minutes of reading became 30 minutes until the light went out. Unlike the Philips Hue Go, which looks like a bowl and begs to be held with two hands, the Glow Light is shaped to grab and go, which made it so useful in my household. Still, we love that the Glow Light is pleasingly intuitive-and it beats deciphering an instruction book and fumbling for buttons in the dark. Just for fun, you can also adjust it to glow in one of six different Gatorade-like colors in the dark-but only the white light works as an alarm light. On the plus side, you can use the clock as a reading light and program it to dim as you wind down and go to bed. I woke soon after the alarm, but presumably deeper sleepers have noted that the sound alarm shuts off too soon. Unlike with the Philips clocks, both the light and the sound stop (instead of just the sound) when you hit snooze at least one online reviewer disliked this, though my husband actually preferred it. ![]() The radio and its alarm rendition of Pachelbel’s Canon sounds tinny compared with our more-expensive picks, and the time display is less subtle, but set it to the bird chirping and ocean waves and turn the display off, and you should be fine. (We found similar flaws in the other under-$50 wake-up lights we tried.) You can also pair the light with one of its seven alarm tones (almost as many as on the Somneo at a fraction of the cost), including the radio. Even at its peak, the light doesn’t quite fill the room-it’s only 130 lux, compared with our main pick’s 300 and the entry-level Philips’s 200. Rather than simulating dawn or dusk, its white light simply grows from dim to bright within a 30-minute window-no fancy color nuances, and with a less gradual change than on our other picks. We also like that you can set multiple alarms during the week and that the sunset component comes with the option of several “wind down” routines, complete with calming sounds and (if you like) visual prompts to guide you in deep breathing. We think it’s the intuitive app that truly makes the upgrade worth it, allowing you to program your sunrise and sunset times and other features much more easily than navigating the buttons on the clock. It also has sensors that detect temperature and humidity, noise, and light levels (which post readings on its app), a built-in nightlight (just tap if you need it), and a USB port. But it offers more alarm sounds and a wider range of brightness levels and programmable sunrise nuances. The Philips SmartSleep Connected Sleep and Wake-Up Light (essentially the Bluetooth-connected version of the SmartSleep HF 3650, previously called the Somneo HF3650, our former upgrade pick) has many of the same features as our main pick, including a natural, red-tinted sunrise and sunset light. It’s for anyone who is eager to use their clock as an accessory for an entire sleep ritual. This upgrade isn’t for someone who is simply looking for a sunrise alarm clock to go to bed and wake up to. The final confrontation with the coven, as well as the adventure’s conclusion, can all be found in Part 3. Reading further assumes that you understand and are accepting of this.įor descriptions of the adventure’s beginning, including Myrrholm, the swamp’s terrain and curse, and the hag coven, refer back to Part 1. The encounters make use of horror elements (undead, gore, body horror) and are not appropriate for DM’s or players who are not comfortable with these themes. Just like part one, a warning must be given before we proceed. Many encounters (10, 12, 13, and 20 in particular) can also have tracks added for the party to find and follow. This can come in the form of knowing the approximate direction of the Banahogg’s center, assuring them of their heading. Parties including a ranger (as mine did), the Keen Mind feat, or even a Dungeon Delver should have a small advantage to navigation. This lends itself extremely well to a random encounter list, as players must rely on an element of luck to find their destination. The Banahogg’s curse makes for difficult navigation. We will touch on this towards the end of this article. ![]() Many of the encounters can be designed to link together, which you may wish to do if your players are rolling as badly as mine did. This plan developed into having a final stretch of encounters, organically leading to the coven’s ritual altar. I then planned to add the final confrontation into the table in place of one of the encounters they had already faced. Instead, I decided that the party would need to face a certain number of swamp encounters. As such, my initial d20 list did not include the final confrontation as a possible option. The Banahogg should be a long and grueling journey through hostile terrain. Some are combat encounters, others are sources of information, but all of them help maintain the atmosphere and aesthetic of the location. In this case, almost all of the encounters show the motivations and machinations of the hag coven, as well as the curse’s effects. One of the most important details to keep in mind when designing and running the encounters is the intent of the character behind them. Part 1 – A Swamp Adventure | Part 3 – A Hag Encounter It covers everything between the players leaving Myrrholm and their confrontation with the hag coven, with in-depth descriptions and instructions on running them. The party must stop them, but what terrors will they have to encounter on the way?Īs the second part of our Banahogg Swamp adventure, we have the d20 list of swamp encounters. Somewhere in the center, the coven is preparing their final ritual.

Install RPM or Debian packages respectively to enable the feature. Currently, EC2 Instance Connect supports Amazon Linux 2 and Ubuntu. To get started using EC2 Instance Connect, you first configure your existing instances. Configuring an EC2 instance for EC2 Instance Connect Because the keys expire, there is no need to track or manage these keys directly, as you did previously. To connect to the instance successfully, you must connect using SSH within this time window. The SSH public keys are only available for one-time use for 60 seconds in the instance metadata. This script updates AuthorizedKeysCommand to read SSH public keys from instance metadata during the SSH authentication process, and connects you to the instance. When the EC2 Instance Connect feature is enabled on an instance, the SSH daemon (sshd) on that instance is configured with a custom AuthorizedKeysCommand script. You can also connect to your instances from a new browser-based SSH client in the EC2 console, providing a consistent experience without having to change your workflows or tools. Ubiquitous access – EC2 Instance Connect works seamlessly with your existing SSH client.Auditability – User connections via EC2 Instance Connect are logged to AWS CloudTrail, providing the visibility needed to easily audit connection requests and maintain compliance.Instead, you generate one-time SSH keys each time that an authorized user connects, eliminating the need to track and maintain keys. This also allows you to move away from long-lived keys. They are only accessible by an instance at the time that an authorized user connects, making it easier to grant or revoke access in real time. Short-lived keys – SSH keys are not persisted on the instance, but are ephemeral in nature.IAM policies and principals remove the need to share and manage SSH keys. Centralized access control – You get centralized access control to your EC2 instances on a per-user and per-instance level.You maintain the installed user keys, handle rotation, and make sure that the bastion host is always available and, more importantly, secured.Īmazon EC2 Instance Connect simplifies many of these issues and provides the following benefits to help improve your security posture: However, running bastion hosts comes with challenges. They provide logging and prevent rogue SSH access by adding an additional layer of network obfuscation. Some organizations also maintain bastion hosts, which help limit network access into hosts by the use of a single jump point. As a result, organizations have to store, share, manage access for, and maintain these SSH keys. When connecting to hosts via SSH, SSH key pairs are often used to individually authorize users. It was created in 1995 and is now installed by default on almost every Linux distribution. The most common tool to connect to Linux servers is Secure Shell (SSH). While infrastructure as code (IaC) tools such as Chef and Puppet have become customary in the industry for configuring servers, you occasionally must access your instances to fine-tune, consult system logs, or debug application issues.
