Buy Magnani Aquarello Italia Round Water Color Block 12.6-White 20 Sheets from Walmart Canada. One small quibble I have with dragging colors into Aquarelo is that you can only drag them onto the text fields in the app. You can even drag a color into the app from the system color picker. Their vibrancy coupled with stellar lightfastness and transparency make for an artist grade paint at a beginner’s price. Type an RGB or HEX value or color name into each text field, and Aquarelo generates a range of colors between the two you entered. There are two text fields for entering color information and a stepper control in the center of the window for indicating how many colors you want to create. Simple exercises in colour value, water control and easy monochromatic. The main UI resembles a swatch of colors with a couple of additional controls. aquarela watercolor ilustrao pintura painting watercolor tutorial - WATERCOLORS. Many of the color utilities I’ve used in the past on the Mac and iOS have been abandoned, so it was good to see a new one released that’s as polished as Aquarelo. Aquarelo is a beautifully-designed new Mac app that cuts through the thicket of formats to help you find the colors you want and convert them to the format you need. The trouble with so many different formats is that it guarantees that at some point, the color value you have won’t be the one you require. Whether you’re a professional designer or developer, or someone who just wants to update a website template, you’ve undoubtedly come across several. There are a seemingly endless number of ways to represent colors.

![]() If they had a very similar price why would people even bother going to a 3rd party shop? because it might be cheaper or they dont have an applestore or a repair shop that is supported by apple.īut that is no reason to try to stop 3rd party repairs. Number 2, it is the most used os on mobile devices so why not create malware for the most used os when you can? and when the os if opensource?Īlso ofcourse they wouldn't allow mods because everyone knows that they wouldnt which is the reason that i said that it would be nice if they did.Īnd if they are so safe they could probably make something that would allow mods to be available without "creating a hole".Īnd ok so you can replace a battery for $20, you could probably do it for even less than that in a 3rd party repair shop and yes the screen replacement is expensive but saying that all the 3rd party repair shops have similar price for that doesn't sound true. ![]() (btw google apps work better on Android) so anyone can just download Android to develop malware and stuff like that but also allows for manufacturers like samsung to change how they want their devices to look. Number 1 and probably the biggest reason, it is open source anyone can use it and change it for free but manufacturesr will have to pay goolge (owners of Android) to have some google services pre-installed etc. years let me explain why Android is less safe. The thing is, the fact you go downloading things on websites that aren’t completely safe makes it likely that you’ve probably been infected a few times you just wouldn’t know about it. So many skins to choose from, and most of them look bad so many options in developer settings and most of them just cause stupid and weird glitches that aren’t beneficial at all. Obviously Android has more features, but I find so many of them utterly useless. Obviously if they allowed it they’d have to allow it for every app and that would mean that every single app could be tracking your keystrokes, watching you or listening to you if anything went wrong. Apple couldn’t create mod support without opening a ‘hole’ in the software! Allowing mod support is basically allowing code from 3rd parties to change the code in the app that’s downloaded from the App Store. Android is less safe than iOS is irrelevant, it’s the fact that it is less safe that matters. The virus that could infect you via Bluetooth is a prime example of that.

H: jet mode, in this mode the pump produces a constant stream, water current.Ĭ: alternate mode, pumps work alternately. Natural-looking waves are generated.ĮLSE: random mode, the pump controller sends its various random orders to change the way it works. W2: waving mode, the pump smoothly changes its efficiency from 30% to 100% on the sine wave pattern. ![]() W1: waving mode, the circulator works intermittently, which results in the appearance of beautiful waves on the surface of the water and the swinging of the interior of the aquarium. The pump head is smaller than the equivalent of OW or RW. The new engine type has better performance at the same power consumption. In addition, the handle has rubber inserts that prevent automatic change of the direction of the water jet outlet. The dampening system of the circulator’s work has been improved, reducing its vibrations. The pump holder allows full adjustment of the water outlet without any restrictions. The SOW series has a stronger magnet, improving the installation of the circulator and allowing it to be installed on a thicker glass. Changes in the structure and changes in the chemical composition of materials used for the production of the engine, rotor and axles are the best solution and are conducive to the continuous work of the circulator in the mode of wave of each type and performance. The new design of the engine assumes the longevity, trouble-free operation and quiet operation of the pump in extreme conditions and at the most demanding mode of operation – waving. Jecod / Jebao has re-designed this element of the circulator. What is the difference between SOW and OW and RW? ![]() Over the years, this solution has been checked by thousands of users, not only in Poland and today enjoys the recognition of aquarists. This solution is only found in the OW, SOW and Hsbao EW series. The SOW series has all the electronics placed in the controller, guaranteeing failure-free operation and noiseless operation. In RW series pumps, part of the motor control electronics is located in the pump head, which may cause failure and loud operation. What is the difference between the SOW and RW series? The SOW construction assumes continuous operation in undulating, where the construction of the motor and materials ensure quiet and trouble-free operation of the device. The pump was created on the basis of many years of experience and has been significantly improved compared to the predecessor of the OW series. This is the latest and the most perfect model of the Jecod / Jebao circulator. Is there a SINE SOW Series circulation pump? ![]() Appropriate circulation ensures good oxygenation of water in the tank and prevents the formation of cyanobacteria. Lack of sufficient water traffic negatively affects the distribution of elements, nutrients and minerals that directly affect the condition of fish, corals or plants. Without proper circulation of water in the tank it is difficult to create a nice, realistic looking aquarium.

Weight is up to 4,741 pounds, nearly half a ton more than the gas-powered XC40, but the Recharge’s front axle only carries 52 percent of that, compared to 58 percent on the T5 AWD. Still, it has a decent amount of poise to go along with its speed, thanks to the battery’s low, central placement under the floor and in the "transmission" tunnel. Since it lacks that car’s adjustable Ohlins dampers and Brembo brakes, the XC40 Recharge isn’t nearly as sporty, but the sheer thrust is impressive. Volvo quotes a sprint to 60 miles per hour in just 4.7 seconds, which is just a few ticks off from the far more aggressive, plug-in hybrid V60 Polestar Engineered. The effortless power and torque is also available at any speed, making genuine fun of quick passes and merging maneuvers. Nevertheless, the XC40 Recharge pinned me to my seat far more aggressively than expected. Output: 402 Horsepower / 486 Pound-Feetīy now, most folks understand that EVs can not only be green, but they can be fast as hell too.Battery: 75.0-kilowatt-hour lithium-ion.Front And Rear Motors: Permanent-Magnet Synchronous.The optional Bowers and Wilkins audio found on Volvo’s 60-series and 90-series cars isn’t available on the XC40 Recharge, but I didn’t miss it one bit. ![]() An air-cooled subwoofer helps reduce energy consumption, but that doesn’t mean it can’t kick out some pretty bitchin’ noises. XC40 Ultimates like the one I drove come standard with a 13-speaker Harman Kardon audio system kicking out 600 watts. It’s a better setup than the minimalist Mach-E’s candy bar–sized instrument cluster or the not-that-customizable Kia or Hyundai’s display. The Recharge also boasts a standard 12.0-inch digital instrument cluster that’s extensively reconfigurable, with beautiful graphics that display a full-screen map, driver assistance, electric range and energy consumption, or a mix of the above. But it’s nowhere near the worst in this segment, and minor frustrations subside with familiarity. Adjusting the climate control temperature is a particular nuisance, requiring a tap of the lower corner of the screen and then a brief wait while a temperature slider pops up. Only the Polestar 2 and its sedan/hatchback/crossover form factor do worse than the Volvo.Įven with the new software, the Volvo’s infotainment isn’t extremely touch-responsive or easy to parse. The cabin rarely feels cramped for even adult-size passengers, but space behind the seats might run out for families with strollers and diaper bags and kids’ diversions. Nowhere are the XC40’s shortcomings more evident than in the cargo area. ![]() In terms of the tape, the XC40 comes up short relative to competitors like the Ford Mustang Mach-E, Hyundai Ioniq 5, and Audi E-Tron. The XC40 also has clever interior features like a deep armrest cubby with a removable waste bin and an accessory hook for purses or backpacks on the passenger side of the center console. Cleaner, less smelly cargo goes under the rear hatch, which reveals 25.0 cubic feet of cargo space with the seats up or 46.0 cubic feet with the seats down. It’s a shallow affair measuring 1.0 cubic foot, but it’s enough space for the on-board charger, tire inflator kit, and perhaps a few odds and ends – your muddy hiking boots will feel right at home. With tons of added power and a low center of gravity courtesy of its 75.0-kilowatt-hour lithium-ion battery pack, the electrified XC40 keeps the gasser’s nippy personality while adding some genuine performance.īefore you ask, yes, the 2022 Volvo XC40 Recharge does indeed have a frunk. ![]() Although it competes with the Ford Mustang Mach-E and mechanically similar Polestar 2, the XC40 Recharge is perhaps most impressive weighed against its gasoline-powered sibling. While EVs based on existing internal-combustion platforms are inherently compromised – and an unimpressive 223 miles of EPA-rated range reflects that – the Volvo XC40 Recharge is nonetheless a lovable offering. ![]() The torquiest vehicle wearing the Iron Mark is actually one of the smallest – the fully electric 2022 Volvo XC40 Recharge, which ties its coupified C40 Recharge sibling with 486 pound-feet courtesy of an electric motor on each axle. If someone asked you which Volvo model had the most torque, you’d probably assume it would be the sporty V60 Polestar or the flagship XC90, right? That’s what I would’ve thought, and I’d be wrong.

It's all done automatically mostly, in a few clicks and gets you results that are stunning even if you can't personally create in this style at all but still enjoy the aesthetic or need it for your project. But the thing is, when your base image is already very very close to being actual pixel art in style, this stuff works miracles with it and brings out the next level. A lot of this stuff is turned around the idea that you take your base image and "pixelize" it then work with it to animate.

Though in recent years its popularity has grown so that it's served year-round (it’s so desired in the United States these days that large American grocery store chains like Trader Joe’s and Whole Foods even offer prepared mochi snacks or desserts), mochi is traditionally eaten during the celebration of the Lunar New Year. Go to town-and happy Lunar New Year! - Cynthia Chen McTernan Test Kitchen NotesĪ chewy, marshmallow-y snack, mochi is made with short-grain glutinous rice. Finally, you can use it to wrap around fillings, like red bean paste or ice cream. I’ve often seen the plain version colored with a few drops of red food coloring, too, to turn it a dainty pink. ![]() Add about 1 teaspoon of matcha powder to the dry ingredients to make green tea mochi, or a flavored extract to the wet ingredients to flavor it to your liking. This is only a basic mochi recipe, waiting to be dressed up however you like. Instead, armed with some flour made from that same sweet rice, you can make your own mochi with a recipe that’s practically foolproof and not nearly as much of a workout. It’s made, more or less, by taking gigantic mallets to a pile of cooked sweet rice and pounding the crap out of it until it forms the chewy, tender consistency that we know and love. Traditionally, making mochi sounds pretty labor-intensive. There’s no better time to learn how to make mochi yourself. Mochi is traditionally eaten around the Lunar New Year (in fact, the Chinese version, nian gao, literally translates as “year cake”), and that means it’s currently mochi high season. ![]() Is there any food happier and cuter than mochi? A gentler incarnation of a marshmallow, it's subtly sweet and a powdery pastel, with a hint of coconut and a pillowy-soft chew. Valerie Browne Lester, the author of Phiz: The Man Who Drew Dickens (2004) has commented: "On listening to Dickens's synopsis of the plot, he would quickly understand that this particular book did not divide itself clearly into two forms of artistic subject matter. This upset Browne, who had always worked on his own. ![]() During this period Leech and his wife became close friends with Charles Dickens and his wife Catherine Dickens.ĭickens suggested that Leech should co-illustrate his next book, Martin Chuzzlewit, with Hablot Knight Browne that was to be published in January 1843. ![]() Mrs Leech was frequently the model for his drawings of young women. They had a daughter, Ada, and a son, John George Warrington Leech. In May 1842 Leech married Anne Viola Eaton of Knutton, Staffordshire. Leech was a tall, handsome man with fine features, a wave of brown hair, and blue eyes. Simon Houfe has argued: "Leech created a dramatis personae of lovable characters who were instantly recognizable to the Victorian public: the sturdy British householder, the henpecked husband, the plain spinster, the intrepid sportsman Mr Briggs, the Brook Green volunteer, and the dandified and time-serving flunkey Jeames." Over the next twenty-three years the magazine published 3,000 of Leech's drawings and 600 cartoons. Leech's humourous drawings were extremely popular and was one of the main reasons the magazine became a great success. The following year he was recruited by a new journal, Punch Magazine, founded by Mark Lemon and Henry Mayhew. He was a skilled and rapid designer, co-operative, witty, and self-effacing."Īlthough influenced by the work of James Gillray and George Cruikshank, Leech's humour was as one critic pointed out "less grotesque, less boisterous, less exaggerated, nearer to the truth and to ordinary experience." John Ruskin, the most important art critic of the time wrote: "John Leech's work contains the finest definition and natural history of the classes of our society the kindest and the subtlest analysis of its foibles, the tenderest flattery of its pretty and well-bred ways, with which the modesty of subservient genius ever immortalised or amused careless masters." Punch Magazineġ840 Leech was employed by the London Magazine and Bentley's Miscellany to supply illustrations. Though the author was an exacting taskmaster, Browne supplied everything Dickens needed in an illustrator. Patten, has pointed out: "Dickens recommended Browne for the position. Leech was short-listed to become Seymour's replacement but the job eventually went to Hablot Knight Browne. While working on The Pickwick Papers Seymour committed suicide on the 20th April 1836. Leech's work was compared to Robert Seymour, who at the time was working with Charles Dickens. For the next few years he produced a series of humourous pamphlets including the Comic Latin Grammar, The Fiddle-Faddle Fashion Book and the Children of Mobility. His first known published work was a pamphlet called Etchings and Sketchings (1835) and included drawings of street characters such as cabmen, policemen, street musicians, etc. Leech left medical school in 1834 and tried to make a living from drawing and painting. The author of John Leech and the Victorian Scene (1984) has argued: "The effect of this collapse, a great disgrace in Victorian London, was to colour the remainder of the younger Leech's life and leave a great scar between father and son." The money was needed as his father's business had failed and in the court of bankruptcy. Leech's teachers should became aware of Leech's superb anatomical drawings and began commissioning him to paint portraits. Leech was educated at Charterhouse where he became friends with William Makepeace Thackeray. As his biographer, Simon Houfe, has pointed out: "The young John Leech was brought up therefore in an atmosphere of sociability, debate, and knowledge of the public prints, mixing with politicians, businessmen, and journalists in his father's public rooms." ![]() John Leech, the only son of a Coffee House proprietor, was born in London on 29th August, 1817. ![]() Although this phenomenon is the main reason for voids, some other methods such as post-thermal treatment and removing phase-separated surfactants assist the structure in creating new voids and enlarging the size of existing voids. This phenomenon creates interconnections, known as pore throats (22) or voids, (23,24) making polymer foams highly permeable. (17−21) Notably, polyHIPE materials possess interconnected porous microstructures because the thin films between the droplets undergo shrinkage during the polymerization. Several studies have been reported on how emulsion stability affects the cellular morphology. ![]() (16) Therefore, the stability of the emulsion has a critical influence on the final structure of the polymer and is determined by some factors like surfactant type and its concentration, temperature, processing conditions, and miscibility of the phases. (14,15) In this technique, the morphology and pore structure of the monoliths are established by the state of the emulsion before the continuous phase is polymerized. (12,13) Polymerization of precursors in the continuous phase of HIPE results in constructing a macroporous polymer (polyHIPE) with a 3D polymer skeleton induced by the emulsion template. (9−11) Droplets in HIPEs are deformed because the fraction of the dispersed phase is greater than 74 vol %, which corresponds roughly to the most compact hexagonal arrangement of uniform spherical droplets. The high internal phase emulsions (HIPEs) technique is a versatile templating approach to produce porous polymers with interconnected channels and tunable pore size, which has been investigated extensively for the fabrication of porous materials with good moisture resistance, low cost, and a simple preparation process. (8) Highly concentrated emulsions can be used as templates for the preparation of highly ordered porous polymeric structures. (1−3) There are various methods to develop porous polymer: phase-separation micromolding, (4) high-internal phase emulsion polymerization, (5,6) block copolymer, (7) and particle or polymer leaching. Recently, porous polymers have been received much attention because they elegantly combine the features of both porous materials and organic polymers including high surface area, flexible backbone, well-defined porosity, and easy synthesis and processing in different forms such as thin films, tabular, or individual spheres. The excellent performance of the catalyst was attributed to the excellent chemical and physical properties of the developed support since it provides an elegant route for preparing site-isolated acid–base dual heterogenized functional groups and preventing their deactivation via chemical neutralization. It was shown that these catalysts were reusable for up to four consecutive runs with a very slight loss of activity. The optimized catalyst showed excellent catalytic performance with 100% substrate conversion and 100% yield of the final product in the one-pot production of β-nitrostyrene from benzaldehyde dimethyl acetal under cascade reactions comprising acid-catalyzed deacetalization and base-catalyzed Henry reactions. The catalyst demonstrated superior activity compared to the homogeneous catalysts, poly(St-DVB)-SO 3H+EDA, poly(St-VBC)-NH 2+chlorosulfonic acid, and poly(St-DVB)-SO 3H+poly(St-VBC)-NH 2 as the catalyst system. The poly(St-VBC)-NH 2-SO 3H(20) sample bearing 1.82 mmol/g of N (base site) and 1.16 mmol/g (acid site) showed the best catalytic activity. The catalytic activity of the poly(St-VBC)-NH 2-SO 3H series with different acid/base densities was assessed for one-pot cascade C–C bond-forming reactions involving deacetylation–Henry reactions. The prepared materials were characterized by Fourier transform infrared (FT-IR), CHNS elemental analysis, energy-dispersive X-ray (EDX), elemental mapping, field emission scanning electron microscopy (FE-SEM), and thermalgravimetric analysis (TGA). The role of various amounts of toluene as the porogenic solvent as well as the amount of 1,3-propane sultone (different ratio of acid/base sites) on the structure of the prepared materials have been carefully investigated. A macroporous dual-functional acid–base covalent organic polymer catalyst poly(St-VBC)-NH 2-SO 3H was prepared using high internal phase emulsion polymerization using vinylbenzyl chloride (VBC), styrene (St), and divinylbenzene (DVB) as substrates toluene as a porogenic solvent, and subsequent modification with ethylenediamine and 1,3-propane sultone. |
