The slate isn't currently available in Australia. Prices have held firm throughout 2022 in general, but there's always the potential for discounts during sales periods such as Amazon Prime Day, so keep your eyes peeled if you want an even cheaper tablet.Īt the time of writing if you want the official Wireless Charging Dock with your purchase, that's another $40 / £40, while the Bluetooth keyboard and a year of Microsoft 365 is another $60 / £60. You can of course buy these tablets direct from Amazon. Those prices include lock screen adverts – if you don't want those, add another $10 / £10 on. For the 32GB of storage model, this slate will set you back $179.99 / £179.99 (around AU$330), and that goes up to $219.99 / £219.99 (roughly AU$400) for the 64GB model. The Amazon Fire tablets remain very affordable. Amazon Fire HD 10 Plus price and availability ![]() ![]() The Amazon Fire HD 10 Plus offers plenty of it, and assuming you're aware of and can live with its limitations, we're happy to recommend it - so much so that we rank it among the best cheap tablets and even the best Android tablets. And really that's what every gadget review comes down to: value for money. It's still super-cheap though, starting at just $179.99 in the US and £179.99 in the UK. The Fire OS software is based on Android, but lacks a few key apps, including all of the Google ones (and YouTube, unless you want to visit YouTube in a web browser) – if you're heavily invested in the Google ecosystem, you might well be better off looking elsewhere. As for the negatives: well, it looks like a cheap tablet, on the whole. ![]() When does skull and bones come out11/20/2023 ![]() ![]() Even if it does launch, we can’t see there being much support for the game past keeping the lights on, and the reception will almost certainly be completely underwhelming.įor more Insider Gaming news, check out our coverage of the ‘tons of leaks’ posted about Assassin’s Creed Mirage. People were tired of Skull and Bone years ago – now they’re just completely exhausted with it. As far as we know, there’s nothing new being introduced to push Skull and Bones past the finish line. While it was set to launch in March 2023, amidst a stacked lineup of fellow blockbusters, the game has now been given the more nebulous release timeframe of ‘ early 2023 to 2024 ‘. We’re very eager for you all to get your hands on Skull and Bones and dive in headfirst to the dangerous and exciting world of building your own pirate empire. PC Image: Ubisoft Share Skull and Bones, the ambitious pirate-themed action game from Ubisoft, has been delayed for the sixth time. As a result, we’ve made the tough decision to move our release date to March 9, 2023. ![]() Recently, Ubisoft decided to triple down on its resources for the Assassin’s Creed franchise, hiring hundreds of developers to come into the fold and put a huge focus on what can be considered its flagship franchise. Our team is hard at work polishing and balancing the experience ahead of the worldwide launch. It doesn’t seem as though huge leaps are being made, which was to be expected. In the latest images to allegedly leak from inside the project, Skull and Bones kind of looks exactly like it did in the most recent gameplay updates, posted back in January 2023. Reportedly, the Skull and Bones project is only being kept alive because of an old deal between Ubisoft Singapore and the Singaporean government. It has been in development for several years, and in that time, almost nobody – critics, fans, or otherwise – has had anything hopeful to say about the game. Skull and Bones Needs to SinkĪt this point, it seems bizarre to believe that Skull and Bones will ever be released, and if it is, there are almost no expectations that it’ll launch in any kind of a decent state. It has been five months since fresh gameplay was broadcasted by Ubisoft, and once again, it seems like the game could be delayed – or a cancellation agreement could be agreed. Recently, a short series of images were leaked on Reddit, with the poster claiming that they reveal ‘the current state’ of Skull and Bones, Ubisoft’s teetering, live-service pirate epic. It has been subjected to countless delays, any gameplay released has been underwhelming, and reportedly, there’s a noose hanging around the project that has been put there courtesy of the Singaporean government. ![]() Skull and Bones may just be the most ill-fated project in the history of gaming. ![]() Costco flow hive11/20/2023 ![]() ![]() įlow Hive honey frames comprise more plastic and plastic surface than the plastic foundations used commonly in conventional modern beekeeping. After the frame is reset, the bees remove the broken covering, and repair and refill the cells. This breaks the wax covering and allows the honey to flow down through the cells into a channel at the base of each frame and out into a collection vessel, obviating the need for extraction equipment such as centrifuges and filters. When the mechanism of a frame is activated by inserting and turning a crank mechanically, the vertical gaps are offset by one half of a cell. Bees fill in these vertical gaps with wax to complete cells, and then fill these cells with honey before covering them with wax. ![]() These honey frames are for use in the Langstroth hive compartment commonly called honey super that is intended for accumulation of honey by bees. The honey frames contain a partially-formed honeycomb with vertical gaps that is made of a plastic free of both BPA and BPS. During extraction, visibly bees are disturbed less than during other methods.ĭesign Schematic with inset at top-right showing the way cells in the honey frame offset during honey extraction to allow honey to flow down for collection. There is occasionally a slight warping at some of the corner joints of both hives.Flow Hive is a beehive brand that has a unique honey frame designed to allow honey extraction without needing to open the beehive. After three years of employment, the unpainted Flow Hive and Langstroth hive units are holding up equally well. ![]() I will confess that I do not like to paint my boxes as I personally prefer the look of natural wood in my apiary, though I know that I am sacrificing the longevity that painted boxes offer. My Classic Flow Hive boxes are crafted from cedar though I believe that there are several options for material available at this time. ![]() The key can be turned at the top of the frame, just like when harvesting honey, to aid in bringing the comb back into alignment. It does take a bit of time to realign the comb and its cells within the flow frames before use. When not in use, the comb cells can easily become misaligned from storage during the “off-season” as they are merely holding together by rubber band-like wires. The plastic honeycomb that is the Flow technology is only in use when the honey supers are in place on top of the hive. When manually taking honey with the use of an extractor we do quadruple filter our product, however, the Flow Hive honey is exceptionally clear and completely free of any debris or residue in comparison.Īs for the durability of the Flow Hive, our hive has been in use for three seasons. The honey is incredibly clear and fully filtered. When the cells do shift, though, the honey drains relatively slowly into your sterilized food-safe jar. The bees had glued the spacing within the cells together so well with propolis that the comb was difficult to crack and shift. In my experience, this plastic comb took a bit of elbow grease to unlock with a key. The center frame parts are made from a virgin food grade polypropylene which is also free from any bisphenol compounds and is widely accepted as one of the safest plastics for food contact.” Honey on Tap with the Flow Hive Third-party labs have tested this material and have found it to be free of estrogenic and androgenic activity. The Flow Hive honey super frames host plastic honeycomb cells, which the Flow Hive website states, “…it’s not only BPA-free, but it is not manufactured with bisphenol-S or any other bisphenol compounds. I’m often asked which hive system I like best and the honest answer is, at the risk of sounding acquiescent, I have no preference. Having the two hives side by side has helped me to learn to harvest honey both manually with the use of a spinner, or extractor, and by way of convenience with the Flow’s tapping system. I also purchased and assembled a Langstroth hive to house bees alongside the Flow. I found the idea of a Flow Hive to be a sensical option and decided to purchase a Classic Flow Hive kit as my first hive - you can find my Flow Hive Review here. I, myself, started beekeeping only in recent years. They can focus on gaining knowledge in the art of hive inspections, pest management, and hive behavior before tackling the manual labor of retrieving honey with an extractor. Some find that beginning their journey into beekeeping becomes more approachable when using a Flow Hive and that this system helps to reduce the steep learning curve. However, many modern backyard beekeepers love the ease with which they can harvest their honey. Some folks feel it’s a hands-off solution to harvesting honey, thus enabling laziness on the part of the beekeeper. Many experienced apiarists believe the technology to be gimmicky, expensive, and unnecessarily adding to the cost of beekeeping. ![]() Free letter logo maker online11/20/2023 ![]() What's important, though, is that different fonts can communicate different messages about your brand.

Carla Fracci, allanagrafe Carolina Fracci (Milano, 20 agosto 1936 Milano, 27 maggio 2021), è stata una ballerina italiana. The beginning and the end of this film follow a perfect circle: great impact the image of the little Carla followed by the one of woman Carla trying to catch a dragonfly, the bird that inspired her in her whole carrer. The soundtrack is appropriate and functional to all the characters' emotions. Her milanese accent was accurate and gives us back an even more authentic Fracci. Carla asked her to emphasize determination, fatigue, strenght and sacrifices during her ballerina carreer. However, Mastronardi, during the months preceding the shoot, followed a training with a dance coach to prepare herself for the role. During the ballet's film shoots, Alessandra was helped by Susanna Salvi, her stand-in, who is ètoile at Rome Opera Theatre. The actress who plays Carla, Alessandra Mastronardi, was directly chosen by Carla Fracci. These aspects make the protagonist Carla a contemporary heroine, who shows us the exceptionalism of a well-lived life, where talent just represents a springboard that makes room for hard work and fatigue, that seem to remain behind the scenes but that permeates in every single performance and every single step. A woman who worked hard to not accept easy compromises, who researched for love as well as carreer, without giving up either of them. The non-linear narration choice allows to emphasize a very precast aspect of Carla: her being a modern woman. When using cinematography to tell the story of a famous person, the danger is to being bombastic, but director Imbucci was aware of this and he avoided that narration style with stereotypes that does nothing but tell in a simple and predictable way the life of a celebrity. In the biopic we can also see her getting back to ballet after the pregnancy thanks to his friend Rudolph Nureyev who encouraged her to come back to La Scala's stage with Nutcracker. She didn't want to give up on something that was part of her life. Much emphasis is also put on the ballerina's choice to become a mother, an unusual choice for an ètoile like her. The story narrated see the rise of her carreer on multiple timescales, not following a chronological timeline. The film is close enough to her life, however, Imbucci wanted to underline certain aspects of her life.

She was an actress, known for Lady of the Camelias (1981), Verdi (1982) and Nijinsky. The screenplay is original and it boasted the consulence of the same Fracci together with his husband Beppe Menegatti. Carla Fracci was born on 20 August 1936 in Milan, Lombardy, Italy. of the heritage of the 19th century repertoire.Emanuele Imbucci's biopic film brings to the screen the life of Carla Fracci, defined by the New York Times "Prima Ballerina Assoluta" and it is freely inspired by biography "Passo dopo passo" released by Mondadori. For the youngest readers, for whom the book is expressly intended, the story represents an opportunity to experience the fervent atmosphere of a period, between the 1960s and 1990s of the twentieth century, when ballet was renewed in a fresh and modern reinterpretation. ![]() The authors, with two different and personal styles, first reconstitute the cultural environment in which this “pas de deux” took place from the ballet scene in post-war Italy, then retrace – in the artistic context of the Fracci-Nureyev duo – the extraordinary individual careers of these two Principal dancers.

This club is excellent off the tee, the fairway, and out of. The head features a 4-piece forged BiTi construction. This club is perfect for the player who has trouble hitting either fairway metals or long irons. Lynx’s first adjustable driver, the Parallax, gives golfers the option of eight adjustable settings, giving five True Loft options and an open or closed club face. Putter was an old Ping Anser and then the Ram FX Bore Thru 3 wood. Wedges were Cleveland 588 and he had the holes drilled in the back. And who doesn't’t want faster ball speeds and longer drives? The driver was the Lynx as were the Parallax irons. What doe this do? The kinetic energy at impact between the club and ball is managed more efficiently and causes the ball to be less affected by drag, delivering optimum ball speeds.

If you are looking for a present to impress your loved one. And that sums them up, doing things their own way rather than just following convention. Thinking outside of the box, I found myself up at the top of London’s BT Tower for the Lynx launch. Normally these events take place at golf courses or driving ranges. We went to Lynx Golf launch event back before Christmas. ![]() ![]() We use Figure, conservation of energy, to find the distance at which kinetic energy is zero. When its speed reaches zero, it is at its maximum distance from the Sun. The object has initial kinetic and potential energies that we can calculate. If an object had this speed at the distance of Earth’s orbit, but was headed directly away from the Sun, how far would it travel before coming to rest? Ignore the gravitational effects of any other bodies. As we see in the next section, that is the tangential speed needed to stay in circular orbit. We noted that Earth already has an orbital speed of 30 km/s. ![]() Let’s consider the preceding example again, where we calculated the escape speed from Earth and the Sun, starting from Earth’s orbit. For real objects, direction is important. We examine tidal effects in Tidal Forces.) Neither positive nor negative total energy precludes finite-sized masses from colliding. (Even for greater values of r, but near the sum of the radii, gravitational tidal forces could create significant effects if both objects are planet sized. If r becomes less than this sum, then the objects collide. They apply to finite-sized, spherically symmetric objects as well, provided that the value for r in Figure is always greater than the sum of the radii of the two objects. Strictly speaking, Figure and Figure apply for point objects. Earlier we stated that if the total energy is zero or greater, the object escapes. It is possible to have a gravitationally bound system where the masses do not “fall together,” but maintain an orbital motion about each other. Energy is a scalar quantity and hence Figure is a scalar equation-the direction of the velocity plays no role in conservation of energy. What is remarkable is that the result applies for any velocity. We have simplified this discussion by assuming that the object was headed directly away from the planet. The object can never exceed this finite distance from M, since to do so would require the kinetic energy to become negative, which is not possible. On the other hand, if the total energy is negative, then the kinetic energy must reach zero at some finite value of r, where U is negative and equal to the total energy. ![]() When the total energy is zero or greater, then we say that m is not gravitationally bound to M. ![]() If the total energy is positive, then kinetic energy remains at r=\infty and certainly m does not return. ![]() Hence, m comes to rest infinitely far away from M. If the total energy is zero, then as m reaches a value of r that approaches infinity, U becomes zero and so must the kinetic energy. In Potential Energy and Conservation of Energy, we showed that the change in gravitational potential energy near Earth’s surface is \Delta U=mg(\,r\to \infty. Potential energy is particularly useful for forces that change with position, as the gravitational force does over large distances. The usefulness of those definitions is the ease with which we can solve many problems using conservation of energy. We defined work and potential energy in Work and Kinetic Energy and Potential Energy and Conservation of Energy.
