![]() Sword and Shield takes place in the Galar region, which is based on the United Kingdom. As with previous games in the series, certain Pokémon are only obtainable in either Sword or Shield, with players encouraged to trade with others in order to obtain all Pokémon from both versions. Players are also able to battle and trade Pokémon with other human players using the Nintendo Switch connectivity features. Players can capture wild Pokémon, found during wild encounters, by weakening them in battle and catching them with Poké Balls, allowing them to be added to their party. By defeating opposing Pokémon in turn-based battles, the player's Pokémon gains experience, allowing them to level up and increase their battle statistics, learn new battle techniques and in some cases, evolve into more powerful Pokémon. The player controls a young trainer who goes on a quest to catch and train creatures known as Pokémon and win battles against other trainers. Pokémon Sword and Shield are role-playing video games with adventure elements and in most cases are presented in a fixed camera, third-person perspective in certain instances free camera movement is available. ![]() By December 2022, Sword and Shield had sold more than 25.68 million copies worldwide, becoming one of the fastest-selling games on the Nintendo Switch, and are currently the fifth- best-selling games on the Switch and second-best-selling titles in the Pokémon series.Īn online multi battle between four players in teams of two Particular praise was aimed at the creatures design, new features, and the emphasis on simplicity, player freedom, and streamlined encounters, although some criticized the game's smaller Pokédex and a perceived lack of polish or depth. Despite this, Sword and Shield received generally positive reviews from critics. When the decision to not include all pre-existing Pokémon from Sword and Shield and onward was announced, it was met with backlash from a segment of the fan community, resulting in a controversy known as "Dexit" (referencing the Pokédex and Brexit) and calls for a boycott months ahead of their release. The two games also reintroduce features previously seen in Sun and Moon and Let's Go, Pikachu! and Let's Go, Eevee!, such as regional forms and roaming Pokémon depicted in the overworld. Sword and Shield introduce 81 new Pokémon- 89 in total including later DLCs- alongside 13 regional forms of pre-existing Pokémon Dynamaxing, which increases the size of Pokémon under certain conditions Gigantamaxing, which additionally changes the form of certain Pokémon and the Wild Area, which is a large, open-world area with free camera movement that contains co-op raid battles. The main objective of the games is to dethrone the Pokémon League Champion, Leon, in a tournament that various other Gym Leaders and rivals also take part in, whilst dealing with Team Yell and a nefarious conspiracy within the League. Like previous installments, they chronicle the journey of a young Pokémon trainer aiming to become the Pokémon Champion, this time in the new Galar region, which is based on Great Britain. Sword and Shield 's concept planning began immediately following the completion of Pokémon Sun and Moon in 2016, while full production began a year later in September 2017. A physical bundle including both expansion packs with the base games was released in November 2020. The games received two downloadable content expansion packs through an expansion pass with The Isle of Armor, released in June 2020 and The Crown Tundra, released in October 2020. ![]() Originally teased at E3 2017 and announced in February 2019, Pokémon Sword and Shield were released in November 2019. ![]() They are the first installments in the eighth generation of the Pokémon video game series and the second in the series, following Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, released on a home game console.

![]() Spindle whorls appeared in the Neolithic era. These whorls are discs of wood, stone, clay, or metal with a hole in the centre for the spindle, which keep the spindle steady and promote its rotation. Ī spindle containing a quantity of yarn rotates more easily, steadily, and continues longer than an empty one hence, the next improvement was the addition of a weight called a spindle whorl at the bottom of the spindle. When held thus, one hand was left free for drawing out the fibres. The other end of the distaff was held in the hand, under the arm or thrust in the girdle of the spinner. It was a short stick, on one end of which was loosely wound the raw material. The distaff was used for holding the bunch of wool, flax, or other fibres. Another bunch of fibres is drawn out, the spindle is given another twirl, the yarn is wound on the spindle, and so on. The twisted yarn is then wound on to the upper part of the spindle. A whirling motion is given to the spindle on the thigh or any convenient part of the body. With the right hand the fibres are drawn out several inches and the end fastened securely in the slit or hook on the top of the spindle. The bunch of wool or plant fibres is held in the left hand. Later, a hook of bone was added to the upper end. At first the stick had a cleft or split in the top in which the thread was fixed. The next method of spinning yarn is with the spindle, a straight stick eight to twelve inches long on which the yarn is wound after twisting. ![]() Later, the fibre is fastened to a stone which is twirled round until the yarn is sufficiently twisted, whereupon it is wound upon the stone and the process repeated over and over. In the most primitive type of spinning, tufts of animal hair or plant fibre are rolled down the thigh with the hand, and additional tufts are added as needed until the desired length of spun fibre is achieved. There has also been recent discovery of plied cord spun by Neanderthals and dating back 41,000-52,000 years. The origins of spinning fibre to make string or yarn are lost in time, but archaeological evidence in the form of representation of string skirts has been dated to the Upper Paleolithic era some 20,000 years ago. ![]() ![]() Main article: History of clothing and textiles ![]() ![]() ![]() We’re one bounce away from three points,” said Ahmed. “When we play our game, when everything is going our way, we’re always the better team. “Especially with what happened (on Wednesday), it’s something that will provide a spark for us to focus and make us a little hungrier because that can’t happen again at home,” said midfielder Ali Ahmed, who made his first start of the season against Montreal.Īhmed had a goal and an assist as a starter against CF Montreal on Wednesday and said his team has the quality to win games, they just need to stay focused. ![]() The Whitecaps are taking on the Portland Timbers on Saturday in the first Cascadia tilt of the season. ”They were a good team but we need to be better.“ We played well…we need more patience,“ said Takaoka. Goalkeeper Yohei Takaoka, who has started six games this season, said Wednesday’s result highlights the need for the team to remain calm. “I want to see us keep developing our style of play, be more clinical in the box and in case things aren’t going our way we don’t lose our minds.” “We’re not used to being the team in charge of a game,” Sartini added. Vancouver has let leads slip away this season before a 5-0 rout of CF Montreal last weekend. “I think we are still not mature enough that when we’re dominating it doesn’t mean that we have to be up in the score every time.” ”We’ve always been a team that defends and counters. ![]() “It’s the first season, at least since I’ve been in charge, where we are a team that play more than the other team,“ said Sartini.

Mixing a high-viscosity or high-molecular weight polymer melt leads to shear-induced overheating due to the large torque induced, required to unleash the polymer chain entanglements. Therefore, it is worth investigating the synergetic relationship, if any, between various physical fields in order to maximize the efficiency of the plasticization effect. The properties of composites in the plasticization process also depend on the control of the velocity, temperature, shear, and pressure fields. Understanding the mass and heat transfer processes in a plasticization system as a function of screw configurations is essential to further develop a more effective screw design to overcome some of the existing challenges. In the past, researchers paid little attention to understand heat transfer in viscous fluid. ![]() However, heat transfer also plays a significant role in plasticizing. These studies may focus on mixing and rheology. Their results showed that mixing performance improved and extrusion pressure reduced. introduced a vibrational force field in the screw plasticization system. Besides, Jiang introduced ultrasonic plasticizing in the extruder to achieve energy saving. Diekmann analyzed the direct-drive single-screw extruders without gearing and results indicated that plasticization capacity increased in the direct-drive system. ![]() Their results showed that the plasticizing capacity improved with the decrease of power consumption in the vane extruder. proposed a novel vane plasticization system in place of screw one to create extensional stress. ![]() Based on the elongational flow and volume transportation, Qu et al. Also, the melt temperatures and pressure fluctuation reduce in the flow channel. In this way, the mixing ability improves under the condition of lower power consumption and viscous dissipation than shear flow. Rauwendaal noted a CRD mixing screw with wedge-shaped barrier region to generate elongational flow. Rydzkowski developed an autothermal screw-disc extruder to induce autothermal effect. indicated that the shearing sections like axial and spiral Maddock elements and Z-elements are often used to improve the melt homogeneity by enhancing dispersive mixing. disclosed a mixture system by combining Pin and Dulmage type screws and also reported their beneficial effect in kneading, homogenization, and ensuring stability of gas/polymer solution. Spalding introduced a distributive melt-mixing type screw equipped with an Eagle mixer in injection molding process and obtained better melting capacity and higher mixing than a conventional screw. developed a barrier-flighted screw with Maddock mixer to achieve good melting performance and low temperature and pressure fluctuations. These reconfigured screws are stated to be better than a standard one. Different from conventional screw, the new types of screw can be roughly divided into four categories: distribution screws, barrier screws, separator screws, and channel screws with variable sections. ![]() The effect of barrel configurations and screw designs on heat and mass transfer has been investigated in the past and proved unquestionably important attributes for determining temperature uniformity and mixing effectiveness in extrusion and injection molding processes. It is very important to optimize the structural parameters and working characteristics of the screw in order to enhance plasticization of polymers. In general, the temperature distribution is not uniform in the process of plasticization this is due to significant friction heating and the low thermal conductivity of polymers. In polymer processing, plasticization screw is an added unit operation that facilitates melting and homogenization of an initially heterogeneous physical system. The thermal homogeneity and stability of polymer melts in this plasticization process is the key to determine the quality of products, especially for biodegradable nanocomposites or microcellular foam materials. The nonlinear effect of polymer plasticization is a multidisciplinary engineering science problem that includes heat transfer, rheology, and flow dynamics among others. Polymer plasticization is a complex process with many uncertain variables, which involves phase transfer and viscoelastic behavior. ![]() ![]() ![]() Flashcards do not take very long to make and will remain a helpful reference for you as you learn.

Keep practicing until you memorize each word.We added a convenient search bar feature just above the military phonetic alphabet to help you memorize each word. We designed this chart to be more than just a visual aid. The complete military alphabet is revealed in chart below. For example, to say “dog,” one would say “Delta-Oscar-Golf.” None of the 26 codewords sound alike, so there is no doubt in what is being communicated. Multiple code words often are combined to form words or expressions. For instance, “Alpha” means “A,” “Bravo” means B, and so on. ![]() To recap: Each word like "Uniform" ( you nee form) or "Yankee" ( yang key) represents a letter of the English alphabet. This same phonetic alphabet is the same as the International Radiotelephony Spelling Alphabet and Western Union alphabet, which also consists of 26 code words. The person you're talking to will understand that you're communicating the word "up" and likely look up above them. To communicate the word "up" say: Uniform Papa. For example, the word for the letter "U" is Uniform, pronounced: you nee form. To use the alphabet correctly spell out words using these distinct words while enunciating each syllable. These codewords are used regularly by government agencies, such as the US Army Infantry, US Navy, US Marines, US Airforce, and even by other militaries around the world. The military alphabet uses distinct words like Juliet (pronounced Jew lee ett k), Charlie (Char lee), and India (In dee ah), as well as codewords like Tango Yankee, Tango Tang, Tango Mike, and many more, to code and decode messages. Miscommunication can cause loss of lives and other tragic circumstances. It is used in the military to prevent miscommunication and to communicate in code. These words are used to ensure oral communication is clearly understood. It is a phonetic alphabet that uses 26 code words.

The 3s subshell would be the lowest in energy, followed by 3p and finally 3d. For example, the orbitals in n = 3 shell are split in three distinct energy levels: 3s with degeneracy 1, 3p with degeneracy 3 and 3d with degeneracy 5. Within every shell the increase in energy follows a general trend s < p < d < f. ![]() Instead, the calculations and experimental data show that, for a given n value, the orbitals that have the same ℓ value are degenerate. In multi-electron systems the orbitals within one shell do not have the same energy in other words the degeneracy is partially broken. The question is, then, which subshell–2s or 2p–will the third Li’s electron occupy? To answer this we have to look at the energies in multi-electron systems first.Ģ.6.2 Energy levels in multi-electron systems. ![]() In one-electron systems these two subshells were degenerate, but in multi-electron systems, such as Li, this is not the case. Lithium’s third electron has to occupy an orbital in next shell ( n =2), which has two subshells, 2s ( n=2, ℓ = 1) and 2p ( n = 2, ℓ = 1). With these two electrons the n = 1 shell is full. ![]() The d subshell can accommodate ten electrons in its five orbitals while the f subshell takes a maximum of 14 electrons in seven orbitals.įor example, two electrons in the helium atom can occupy the 1s atomic orbital ( n = 0, ℓ = 0 and m ℓ = 0) as long as they have different values of m s: one must have +½ the other – ½. The p subshell (ℓ = 1) contains three orbitals (mℓ = –1, 0, +1) and can accommodate six electrons in total. Since subshell s contains only one orbital, it can accept only two electrons. The Pauli Exclusion Principle limits the number of electrons each subshell can accommodate. Two such electrons placed together in one atomic orbital form an electron pair (or ⇅). Graphically, we represent an electron with m s = + ½ using an arrow pointing up (↑) and an electron with m s = – ½ using an arrow pointing down (↓). The consequence of the Pauli exclusion principle is that two electrons can share, or as is commonly stated occupy, one atomic orbital defined with specific n, ℓ and m ℓ as long as they have different values of m s quantum number. It is not possible for two electrons in a multi-electron system to have the same value of the four quantum numbers. With these four quantum numbers at hand we can look at the Pauli Exclusion Principle which can be stated as follows: For the multi-electron atoms we have to include the spin quantum number, m s, as well. 15Ģ.6.1 Pauli exclusion principle–Bringing the electron spin into the picture.Īs we have seen earlier, the three quantum numbers n, ℓ and m ℓ appear in the solutions of the Schrödinger equation, the solutions which are wave functions referred to as atomic orbitals. The two orbitals, however, differ in energy level and volume-the 1s orbital in the He atom has smaller volume and is lower in energy in comparison to the 1s orbital in the H atom as the higher nuclear charge of the He nucleus draws electrons closer. ![]() For example, the He 1s orbital has the same shape as the 1s orbital shown in Figure 2.5. In its simple form, this approximation states that all electrons in a multi-electron system can be described using the atomic orbitals determined for the one-electron systems. One important starting point when solving the Schrödinger equation for these systems is the orbital approximation. Again, we are particularly interested in solutions rather than mathematical procedures. The approximations are based on the sound experimental data as well as well-established mathematical tools. For the multi-electron systems, the solutions are only approximate. As mentioned previously, the exact solutions for the Schrödinger equation can be found only for the one-electron systems. ![]() |
