Other new features of the Spectra Synergy Gold With the new Spectra Synergy Gold, you’ll be able to customize the suction speeds on each breast for comfort and optimal milk removal. This is very normal, and many mothers online have unique names for this including, “slacker boob”, or more colorful names like “sh**ty tittie” depending on how frustrated they are with it! If you’ve breastfed before, you may have noticed that once side commonly produces more than the other. This new Spectra pump is the only pump on the market that offers this technology currently. We’ll just get straight to it! The BIGGEST difference on the new Spectra Synergy Gold pump is that it has two motors! This gives you the ability to control the settings differently on EACH SIDE. So, why is the Spectra Synergy Gold (Spectra SG) so exciting? The BIG difference between Spectra Synergy and S1/S2 There’s a video at the bottom of this post with the basics of Spectra Synergy Gold VS Spectra 1 as well as info about the CaraCups. Spectra just put their newest pump (Spectra Synergy Gold) available for preorder, along with a few new accessories as well! I (of course) ordered them and they’ll be a video with a FULL review on the YouTube channel soon (make sure you subscribe so you don’t miss it!) If you want a solid pump you know will work great for you? Spectra is my go-to brand. I’ve personally used and recommended the Spectra 1 and Spectra 2 over and over again because they are just fantastic breast pumps. Spectra breast pumps have been a long time favorite of many moms.

Royal historian Marlene Koenig says Charles is like a 'caretaker' of the throne for the future. Charles Is letter to Lords Jermyn and Culpepper and John Ashburnham. At 73, hes the oldest person to become a monarch in the UK, leaving Prince William as his heir. Sources and commentary by Professor Peter Gaunt. Charles was convicted of high treason and beheaded in 1649 outside the Banqueting House in London, just up the street from Parliament. King Charles III inherited the British throne after Queen Elizabeth II died. He took the throne in 1625, and his reign saw a growing power struggle between the crown and Parliament, which sought to limit the king’s powers.Īfter the king attempted to arrest lawmakers in the House of Commons in 1642, hostilities erupted into the English Civil War, which ended with victory for the parliamentary forces of Oliver Cromwell. King Charles I is the only British sovereign whose rule led to revolution and the temporary abolition of the monarchy. Since October 2021, there have been 330 confirmed cases of avian. Some observers thought the new king might prefer a different name because of the historical baggage associated with the two previous British monarchs called Charles. King Charles has congratulated scientists for their work in combating the largest-ever avian influenza outbreak in the UK. While the queen used her first given name, her father, King George VI, was named Albert Frederick Arthur George and called Bertie by friends and family. LONDON (AP) - Britain’s new monarch is named King Charles III - but that was not inevitable.Ĭharles Philip Arthur George could have chosen another royal name when he took the throne after the death of his mother Queen Elizabeth II on Thursday. If patients who are entitled to receive personal healthcare services free of charge prefer to receive additional services or procedures, they must pay for these services or procedures themselves. What factors affect the price? Centre standard priceįor consultations and examinations with a referral letterĪccording to the Law on Healthcare System of the Republic of Lithuania (part 5 of article 49), if patients prefer to receive more expensive services, materials and procedures, they must pay the difference between the factual price of these services, materials and procedures and the price of the services, materials and procedures that are provided free of charge following the rules defined by the Ministry of Health of the Republic of Lithuania. The actual price is discussed during the consultation before the procedure considering the extent and complexity of the procedure. The price of a basic procedure is the lowest procedure price. The prices of the specific services are available at Reception and/or during the consultation with the physician. The total price of a dermatology service includes the price of the procedure and all materials required for the procedure. In the case of dermatology services only the price for the physician's service is indicated. In the case of surgical treatment additional costs for anaesthesia, implants and substances preferred by the patient as well as individually chosen menus are applied. The prices of the specific services are available at Reception. If a swab is required to carry out a test, this may sometimes incur additional costs. The price of blood laboratory tests is comprised of the test price (indicated in the pricelist) and the price for collecting the blood sample. The prices of the specific service are available at Reception. The price of an instrumental examination consists of the price of the examination and the required materials (contrast medium, injections of the contrast medium, anaesthesiological care, imaging, etc.). Should the patient chose particular implants or substances or order individual menus, these will incur additional costs. This price applies to patients not covered by compulsory health insurance, who do not have a referral letter from their doctor (except radiological examinations, for which a referral letter is mandatory) when the referral letter does not meet the requirements defined by the legal acts when the disease is not included in the list of reimbursable diseases when the referral letter has expired (30 days), and in other cases indicated in the Rules for the Provision and Payment of Commercial Personal Healthcare Services approved by Order No. 357 of the Minister of Health dated 30 July 1999 (with subsequent amendments), the patients should pay for such services themselves. If you're looking to stream both in-game audio and Nintendo Switch Online chat features through the app at the same time, there's no other set of cups like it.

Read more: SteelSeries Arctis Nova Pro review (opens in new tab) The real test of this one’s worth will be how the construction materials hold up over prolonged use, but if you don’t mind a slightly awkward cable situation this has sound quality and comfort for days. When you’re wearing the unit, there’s very little sound bleed so low-end resonances can really bark. Sound quality is the biggie here though, and the Nova Pro retains Steelseries’ characteristic flat EQ for the most part but finds more pronounced bass via the pleather contact points. This wired model plugs into a GameDAC base station via a 3.5mm connection, and although the supplied cable is an awkwardly short 1.2m, the base station’s controls and display are super intuitive and useful. We do wonder how it’ll hold up over time, though - those plastic hinges and new headband design don’t look as durable as on previous models. The result of that is an even comfier fit than previous Arctis models provided, and it was already their strength. The real showstopper here is the earcup cushioning, though - softer pleather or memory foam you’ve never touched. The earcups themselves feature a similar shape, but now have recesses and emphasize a circular motif in the middle, finished in a magnetised and swappable plate featuring Steelseries branding. Gone is the old ski goggle headband design, replaced by a new internal headband suspended from press studs on the headband inner. If you've got a very, very healthy amount of cash to drop on a Nintendo Switch headset you’ll definitely be interested in Steelseries’ new wired flagship Arctis model.įirst and foremost, it’s a step up in comfort and looks. Read more: SteelSeries Arctis Nova 1 review An easy plug and play system that won't break the bank (or your backpack), this is the best Nintendo Switch headset for those looking to spend less than $60 / £60. Overall, the SteelSeries Arctis Nova 1 represents excellent value for money in this cheaper price range. We did notice that the fabric material did get warm after a while, though. An elasticated inner headband keeps the plastic main band off the noggin well, and some memory foam in the cups themselves goes a long way as well. That lighter weight is playing a large role here, ensuring the Nova 1s remain ergonomic during longer play sessions and aren't a burden to take with you on the go. The design is a far cry from the luxuries of more expensive models, but you've still got a comfortable form factor overall. While the lower end is a little more artificial (there are some sacrifices to be made for the cash) this is a particularly well tuned set of cups for the price. As it stands, we were impressed with the well balanced sound on offer, with rich dialogue and a wide open soundstage of a plethora of genres. That just goes to show how far audio technology has developed in recent months - for $60 / £60 you're getting quality that would have been well into the three figures just a few years ago. With the Nova Pro is obviously far out in front, there was a solid similarity between the sound profile here and in the SteelSeries Arctis Nova 7. We were surprised to find that the audio coming from the Nova 1s was actually comparable to that of models further up the line. However, you're still getting 2022 level quality - and it's surprising how far that Arctis line will take you even in these cheaper seats. This is a wired headset with a smaller footprint, so there's no need to worry about bulking out your backpack with a worryingly expensive piece of kit. The much much cheaper SteelSeries Arctis Nova 1 still offers that same premium pedigree, but in an affordable $59.99 / £59.99 form factor that will serve Nintendo Switch players particularly well. SteelSeries has been making some serious moves recently, with the Arctis Nova Pro Wireless topping the charts (and the price range) with its audio prowess. A series of novelizations of Doom 3, written by Matthew J. The game was followed by Resurrection of Evil, an expansion pack developed by Nerve Software, in April 2005.

She also considered the novella a gift to devoted Twilight readers, which is why she asked her publisher to make it available for free online. Meyer liked the idea of publishing it before Eclipse hit theaters, to give fans an introduction to Bree. Meyer thought the manuscript might work well as part of The Twilight Saga: The Official Illustrated Guide, a tome still awaiting a publishing date, but at nearly 200 pages, it was something her publisher thought worked better on its own. "I was thinking a lot about the newborns, imagining their side of the story, and one thing led to another." The novella came in handy during the filming of The Twilight Saga: Eclipse: screenwriter Melissa Rosenberg, director David Slade, and actors Xavier Samuel (Riley), Bryce Dallas Howard (Victoria), and Jodelle Ferland (Bree) all read it before filming so they could better understand the characters. It was just something she had started working on while she was still editing Eclipse. On her official site, Meyer says she never intended to publish The Short Second Life of Bree Tanner as a stand-alone book. From June 7 to July 5, fans were able to read the book for free online at which also provided a link to the American Red Cross website where they could donate to support relief efforts in Haiti, Chile, and around the globe. on Jin hardcover (with $1 from each sale going to the American Red Cross International Response Fund). The Short Second Life of Bree Tanner is a 178-page novella that chronicles the journey of Victoria’s newborn vampire army as they prepare to close in on Bella and the Cullens. Felix executes her by tearing her into shreds and burning her. She thinks towards Edward to be nice to Fred if he happened to come over there. Bree's sorrow was that she could never reveal to Fred the lies Riley had told them all. Jane disallows it and orders Felix to kill her. Jane tortures Bree for information about her creation and the newborn army the Cullens offer to take her in. Bree struggles to resist Bella's scent, but manages. The rest of the Olympic coven arrive along with Bella Swan, just as the Volturi turn up. She also realizes that Diego is dead when she finds no trace of him she then surrenders to Carlisle and Esme Cullen when they offer her asylum, and is taken to the field where the main fight took place and held captive. Upon reaching the battlefield, she discovers that the newborn army has been decimated by the combined efforts of the Cullen family and the Uley pack and that they have been abandoned by Riley and Victoria. He offers Bree to bring Diego along with her if he would come. Fred then takes off on his own to Vancouver, promising Bree that he would wait for a day for her over there. Bree refuses, however, still mistakenly believing Diego to be alive and waiting for her. He, like her and Diego, has suspected Riley and Victoria's intentions to let the newborns die in battle, personally destroying any survivors, and suggests that they leave before the fight starts. The day of the battle, Fred, also known as 'Freaky Fred', a particularly gifted member with the power to create a repulsing shield around himself, tries to convince Bree to escape with him. Unbeknowst to her, Diego has actually been tortured to death by Victoria and Riley. He tells Bree that he has sent Diego on a reconnaissance mission with her( Victoria was referred to as her), and that they will shortly be reunited. Riley starts preparing the newborns for the battle with the Cullens, claiming that for four days a year it is safe for vampires to walk in sunlight. Diego confronts Riley about their ability to survive in sunlight, and doesn't return, leaving Bree frightened and confused. Both Bree and Diego grow uneasy as they are unsure whether Riley is deliberately lying to them or simply ill informed in the end, he was lying.īree and Diego doubt Riley's intentions and start to wonder whether they and the other newborns are simply meant to serve a certain purpose. Together, they discover that they are able to go out in the sunlight without being fried, and that wooden stakes don't kill them, contrary to what Riley Biers, who was made straw boss of the army, has told them about sunlight being deadly to vampires. The story tells of Bree Tanner's short life as a newborn vampire and her experiences as a member of the Seattle newborn army.ĭuring a regular night hunt, she is out hunting in Seattle with three other newborns when she meets and befriends Diego, a high-ranked newborn they gradually fall in love with each other through the night. Some commanders view ( PDF) wargaming as a childish endeavor or an oversimplification of the complexities of warfare, unworthy of the requisite time and resources. Whether attempting to establish or grow wargaming initiatives, resistant or reluctant leadership is typically the first barrier to overcome. However, significant challenges remain if educational wargaming is to grow and persist at the tactical edge of the Joint Force. Admittedly, the 2015 memo by DEPSECDEF Bob Work and the 2020 guidance ( PDF) on PME by the Joint Chiefs of Staff have recently rekindled interest in game-based learning. By conducting wargames, tactical leaders from Sergeants to Majors not only familiarize themselves with capabilities but also face a thinking and adaptive adversary. Berger clearly stated, “Wargaming historically was invented to fill this gap, and we need to make far more aggressive use of it at all levels of training and education to give leaders the necessary ‘reps and sets' in realistic combat decisionmaking.” As concepts like multi-domain operations evolve and new capabilities are fielded, the necessity for educational wargaming within the operating forces becomes increasingly poignant. In the “Commandant's Planning Guidance,” ( PDF) General David H. Share on TwitterĪlthough the Soviet Union is gone, new competitors and challenges are on the operational horizon, such as a growing Chinese navy ( PDF) and the rising threat of Russia's long-range missile capabilities. Wargames provide a dynamic environment to explore and examine a variety of challenges and concepts along the strategic, operational and tactical levels. Unfortunately, over time, the ability of uniformed servicemembers to design or conduct their own wargames has largely atrophied. Emphasizing the interplay of sensors and weapon systems, Harpoon enabled players to realistically explore the dynamics of modern naval warfare. Similarly, Harpoon, a tactical miniatures wargame series, was originally used as a training tool for naval officers during the Cold War. With its memorable 1/285 scale miniatures and emphasis on small-unit tactics, Dunn Kempf enabled soldiers to familiarize themselves with enemy capabilities, execute varying battle plans, and learn through competition and iteration. From 1977 to 1997, the Dunn Kempf wargame ( PDF) was widely used as a teaching tool and explored potential combined arms warfare in Europe against a Soviet-led Warsaw Pact. Most notably, “Strategos” stressed accessibility across echelons and was later disseminated to company-sized units. In 1880 American Army officer Charles Totten published “Strategos,” a series of tactical wargames with varying scenarios and levels of complexity. The enduring popularity of Kriegsspiel centers on its ability to provide players a means to garner experience, explore difficult challenges, and hone decisionmaking skills under stress. When observing a Kriegsspiel demonstration in 1824, General Karl von Muffling, Chief of the Prussian General Staff, famously exclaimed, “This is not a game, this is a war exercise! I must recommend it to the whole army!” Subsequently, a copy of the wargame was supplied to each regiment in the Prussian army, which spurred the formation of Kriegsspiel-centric clubs. As an educational tool, wargaming fosters critical thinking and innovation, but most of all, it helps prepare tactical leaders for future challenges.įrom its inception in the early 19th century, the Prussian Kriegsspiel, the progenitor of modern wargaming, was designed to educate and train Prussian officers for future wars. Wargames provide ( PDF) a dynamic environment to explore and examine a variety of challenges and concepts along the strategic, operational and tactical levels. The use of wargames to teach both tactics and strategic thinking lies at the heart of professional wargaming. Success depends on senior leadership support in the form of institutional funding and enduring partnerships with wargaming organizations. Thus, to systemically reap the dividends of educational wargaming, the Joint Force should aim to reestablish the tradition of educational wargaming within tactical units. The rare employment of educational wargaming within tactical units is episodic and limited in scope. At the tactical edge, wargaming is generally limited to the military planning process and course of action analysis ( PDF). The majority of educational wargaming is confined to the classroom, far removed from frontline units. In contrast, educational wargaming remains generally underdeveloped and underutilized in the operational force. Army War College and the Marine Corps War College are admirably expanding game-based learning in their curricula. Educational wargaming is increasingly prevalent in the pedagogical toolkit but remains concentrated at the higher levels of Professional Military Education (PME). The centrifugal governor was invented by Christiaan Huygens in the seventeenth century, and used to adjust the gap between millstones. It was not until the mid-19th century that the stability of feedback control systems was analyzed using mathematics, the formal language of automatic control theory. Thus, it was more of an art than a science. The design of feedback control systems up through the Industrial Revolution was by trial-and-error, together with a great deal of engineering intuition. They also described a feedback controller. Two-step level controls for fluids, a form of discontinuous variable structure controls, was developed by the Banu Musa brothers. The Persian Banū Mūsā brothers, in their Book of Ingenious Devices (850 AD), described a number of automatic controls. The appearance of the mechanical clock in the 14th century made the water clock and its feedback control system obsolete. This was the earliest feedback-controlled mechanism. In Ptolemaic Egypt, about 270 BC, Ctesibius described a float regulator for a water clock, a device not unlike the ball and cock in a modern flush toilet. It was a preoccupation of the Greeks and Arabs (in the period between about 300 BC and about 1200 AD) to keep accurate track of time. Job losses and downward mobility blamed on automation have been cited as one of many factors in the resurgence of nationalist, protectionist and populist politics in the US, UK and France, among other countries since the 2010s. The World Bank's World Development Report of 2019 shows evidence that the new industries and jobs in the technology sector outweigh the economic effects of workers being displaced by automation. It was during this time that industry was rapidly adopting feedback controllers, which were introduced in the 1930s. The term automation, inspired by the earlier word automatic (coming from automaton), was not widely used before 1947, when Ford established an automation department. The mathematical basis of control theory was begun in the 18th century and advanced rapidly in the 20th. This closed-loop control is an application of negative feedback to a system. In the simplest type of an automatic control loop, a controller compares a measured value of a process with a desired set value and processes the resulting error signal to change some input to the process, in such a way that the process stays at its set point despite disturbances. It can range from simple on-off control to multi-variable high-level algorithms in terms of control complexity. Automation has also found a home in the banking industry. Examples range from a household thermostat controlling a boiler to a large industrial control system with tens of thousands of input measurements and output control signals. The benefit of automation includes labor savings, reducing waste, savings in electricity costs, savings in material costs, and improvements to quality, accuracy, and precision.Īutomation includes the use of various equipment and control systems such as machinery, processes in factories, boilers, and heat-treating ovens, switching on telephone networks, steering, and stabilization of ships, aircraft, and other applications and vehicles with reduced human intervention. Complicated systems, such as modern factories, airplanes, and ships typically use combinations of all of these techniques. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic devices, and computers, usually in combination. Minimum human intervention is required to control many large facilities, such as this electrical generating station.Īutomation describes a wide range of technologies that reduce human intervention in processes, namely by predetermining decision criteria, subprocess relationships, and related actions, as well as embodying those predeterminations in machines. |
