A commercial and traditional bonding agent, Chemosil (see Materials and Methods), is used as the reference system. The different bonding systems are compared in terms of reactivity toward the EPDM rubber, and the impact of the ability of the primary amines to covalently link the polymer films inter- and intramolecularly is discussed. The fracture toughness ( ) and cohesive-to-adhesive fracture ratio ( A r) are used to quantify the adhesive strength and performance of the joints. Bonding properties are evaluated by peel testing and subsequent three-dimensional (3D) scanning of the fractured surfaces. Samples are then installed in a sample holder and compression-molded with EPDM rubber covalently linking rubber and polymer brushes (see Figure S1, Supporting Information). The brush films are analyzed by ellipsometry, infrared reflectance–absorption spectroscopy (IRRAS), and X-ray photoelectron spectroscopy (XPS). First, PGMA and PDEAEMA polymer brushes are grown from stainless steel (SS) along with PGMA polymer brushes modified using either allylamine, diallylamine, or propylamine as the nucleophile. The PGMA brushes can subsequently be modified, exploiting the fact that nucleophiles such as amines, (17,18) thiols, (19) and azides (20) are able to open the oxirane ring.įigure 1 presents an overview of the steps involved in this work. (13−16) Specifically, poly(glycidyl methacrylate) (PGMA) and poly (PDEAEMA) polymer brushes may be grown from various surfaces using a controlled radical polymerization. (2,12) Several methods have been designed to ensure both durability and high grafting densities of polymer brushes generating a nanometer-thin primer layer. Anchoring of polymer brushes to metal surfaces is a versatile approach of making a metal compatible with a given coating. In this work, we used the controlled radical polymerization approach because the aim was to produce brushes covalently anchored to the substrate with good control of length and with minimal cross-linking of the brushes. Several methodologies can be applied for a surface-confined polymerization, that is, free radical polymerization (thermal, photochemical, or radiochemical), controlled radical polymerization, anionic polymerization, or electropolymerization. For these reasons, development of highly efficient thin-layer primer systems would be desirable. (10,11) The challenge with these primers is that they are applied in large amounts (at least a few micrometers in thickness) and are unable to establish covalent bonds all the way from the metal surface to the rubber. Solution-based organic primers and binders are widely employed, and components such as chlorinated polymers and poly(butadiene) are required (among a variety of other additives) to obtain strong adhesion. (9) Still, pretreatment of the metal is the most extensively used approach to enhance metal–rubber adhesion. Functionalization of rubber includes halogenation, cyclization, or copolymerization with polar monomers to increase the wettability. One interesting approach for handling the adhesion issue is through a chemical modification of either the rubber or the metal. (8) Unfortunately, most rubbers have a low wettability, and it is hard to create adhesion to metals, rendering interlocking designs the common solution. (5−7) What makes rubber particularly efficacious for such applications is its high elasticity and resistance to oxygen, ozone, ultraviolet light, and heat. Cross-linking of polymer brushes by intermolecular reactions by the primary amines proved to have a significant impact on the type of fracture (cohesive/adhesive) and the performance of the adhesives.Īdhesion of rubber to a metal is important for various purposes, including bridge bearings, mounts in car engines, tires, and so on. The obtained values of (15.4 ± 1.1 N mm –1) and A r (1.00 ± 0.01) matched those obtained for a micrometer-thick commercial bonding agent. For the nanometer-thin PGMA films modified with allylamine, in particular, full cohesive fracture was obtained. Two parameters, the fracture toughness ( ) and the cohesive-to-adhesive fracture ratio ( A r), were calculated to evaluate the strength and the performance of the coupling, respectively. The efficiency of the novel bonding solution was evaluated through peel experiments. All samples were compression molded with uncured ethylene-propylene-diene M-class rubber and dicumyl peroxide and vulcanized for 12 min at 170 ☌. Stainless steel (SS) surfaces were grafted with poly(glycidyl methacrylate) (PGMA) brushes that were post-modified using allylamine, diallylamine, and propylamine as reagents. Here, The $options with the “i” parameter specify that we want to carry out the search no matter if we find the letters ‘Co’ in lower or upper case. Now, we will apply the below query to find where the string contains: db.details.find() The following documents were inserted into the details collection.

Prepare to battle the challenging terrain and roads covered in ice, snow, mud, or water. Realistic graphics and physics are some of the main attributes which make the SnowRunner game (Epic Games key) so immersive and engaging. The game can be played in a co-op mode with up to 4 players on the map, meaning that you can modify your truck with a maintenance addon and help your friends if they get stuck in a bad situation. The title includes vehicle brands like Freightliner, Ford, Chevrolet and each truck can be customized with upgrades that will contribute to the SnowRunner gameplay or simply serve as stylish accessories. The SnowRunner game Epic Games key provides a generous selection of 40 licensed trucks, among which you’ll find both pickup trucks and semi-trailer trucks. On top of that, the land is filled with secret rewards for you to discover! Customizable trucks Due to the difficult terrain SnowRunner gameplay can become challenging but after every completed contract changes will be introduced to the map - new bridges and roads will appear in the open-world giving you more options to tackle the objectives. With each completed mission, you’ll gain monetary rewards that you will spend on vehicles, new parts, and performance upgrades. The setting of the Saber Interactive’s SnowRunner game (Epic Games key) is a dynamic open world which you’ll travel by taking up trucking assignments known as contracts. Otherwise, if you happen to be a newcomer to the genre, don’t be surprised if you’ll find a new passion! Changing open world If you’re into trucks, you have a lot to discover in this game. This also means any vehicles in the unexplored areas are inaccessible until you find them again.SnowRunner game Epic Games key could be considered a gaming equivalent of a popular TV show called Ice Road Truckers but its leaps and bounds beyond just that! The title is developed by an American studio Saber Interactive and published by Focus Home Interactive - these are the same people who have brought us similar games in the past, most notably a title called MudRunner – a predecessor of this particular extreme off-road driving simulator. This means if you have not been to a map on the XGP version then it won't copy the explored areas for that map and you'll need to re-explore.
There’s just not enough time to get to know your date before having to decide to engage romantically. The first is a surface-level and often heavily flirtatious introduction the second is where you choose if you’re keeping it friendly or going for a more intimate relationship - and you'll usually get another chance at the third level to romance if you denied their first advance. Since they’re almost all in your debt for your heroic rescue efforts you’re not starting from the point of having to win anyone’s favor - you’re choosing who to reject, if you decide to deny anyone - so already we’re cutting right to the chase and skipping the introductory phase we see in games like Hatoful Boyfriend and Hakuoki.Įvery weapon-person has six levels of romance, each with a corresponding date encounter, which increase as you gain experience with the weapons in the dunj by slaying enemies. By typical dating sim standards, romance is exceptionally quick and easy in Boyfriend Dungeon. Things get even weirder in the beach town when weapon-people start going missing, so naturally, you delve into the dunj only to find them and, of course, date them. As it is, these romances escalate far too quickly if I were in their very inexperienced shoes, the way they go about approaching their partners' problems and romantic gestures would only make sense if they had far more disastrous outcomes. Talk about whiplash! More divergent dialogue options would have made more sense and let us consistently roleplay as either the naive romantic novice or the suave natural - or maybe even a character who had a shred of dating experience. They go from not even being able to say they can stand up for themself in one instance to suddenly navigating rather intensely flirtatious situations. It's a fun setup, though some moments in the romantic journey get a little bumpy given how inconsistent your character is with their available dialogue options. Wielding someone isn't inherently romantic, but these weapon-people aren't hesitant about getting flirtatious. In Boyfriend Dungeon, some people can magically transform into a cool weapon that reflects their personality: a cautious and artistic woman named Valeria can transform into a pretty dagger, while a K-pop idol morphs into an awesome lasersaber. You're not dungeon crawling alongside another fighter, but are instead wielding potential partners and using them to slice or bash enemies into submission. It turns out the dating hot spots are on the beach or in the town's nightlife, but excitingly, they're in "dunj" or (what the cool folks here call dungeons) where people can go dungeon crawling for money - and romance. In Boyfriend Dungeon, you assume the role of a person who's never been on a date before and is sent to a cute beachside town for the summer to find love. Limited dungeons, having to interact with an antagonist in an uncomfortably close way, and an awkwardly rushed romance system kill the mood, too. Even worse, its roguelite structure tied to romance systems meant juggling spending time with who you like versus the weapon you actually want to play with. But while the combat is entertaining enough while the enemy variety lasts and Boyfriend Dungeon certainly has a cast of pleasantly designed characters, it fails to offer much nuance in its relationships. That’s an exciting concept because games in this genre are often defined by romances that are longer and more choice-based than what you'll find in something like Mass Effect. When I first heard the delightfully wild concept of Boyfriend Dungeon, I was keenly interested in the idea of playing a game that gives the dating sim formula a different kind of action: Hades-style isometric battles in which your weapons are also your love interests. Moreover, these protective gears protect riders from serious injuries. Protective gear such as helmet, gloves, knee cap, elbow guard, and spine guard plays an important role in improving road safety. Protective gear dominated the motorcycle gear market in 2018 and is expected to maintain its lead throughout the forecast period. Furthermore, product innovation, coupled with product line extension leading to premiumization, is expected to fuel the demand for motorbike riding gear over the forecast period. Due to the increasing number of double-income families, demand for premium motorcycle is growing across the world, which led to an increase in the spending on protective riding gears.Īs a result of the growing demand for premium motorcycle, market players are offering innovative and stylish products, provide efficient safety, and are relatively costlier than traditional protective clothing. Moreover, these protective gears are thicker than conventional clothing with waterproof closures and pockets, zips, higher collars, and are even fitted out with armor.ĭemand for innovative products that offer efficient use and safety features is growing among the consumers owing to which players operating in the global protective motorbike riding gear market have increased their spending on R&D to offer innovative products with added safety features. Nowadays, motorbike riding gears such as helmet, gloves, jackets, knee and elbow guard, spine guard, pant, and footwear are used for protective purposes while riding a bike. Increasing disposable income of the urban people, coupled with a desire to travel and live a fulfilled life, has led to an increase in spending on motorcycle protective gear. The increasing number of motorbike riding enthusiasts, coupled with increasing awareness related to road safety in various countries across the world, is likely to drive the market from 2019 to 2025. Of course, if you get caught in a sudden downpour, you will get wet – unless you have a set of waterproofs with you – but if it’s hot enough that you want as much ventilation as possible, then the chances are you may not mind a little rain and you’ll probably dry out fairly quickly anyway.The global motorbike riding gear market size was valued at USD 11.2 billion in 2018. The same goes for gloves and boots choose ones that are ventilated to let as much cooling air in as possible. The first time you wear mesh clothing, it can be very disconcerting and leave you feeling vulnerable but the cooling effect is amazing, particularly if the ambient temperature is high. For example, mesh clothing has proper material in impact and abrasion zones but in areas that are unlikely to hit the ground, such as the front of the chest or the inside of the arms, they have mesh that allows vast amounts of cooling air in. So you may want to consider something a bit more lightweight, a bit cooler, a bit more appropriate to the conditions.ĭepending on the weather, you can choose clothing that from a cooling point of view, does not exist. While your year-round textile kit will work well into the summer, you may find that however breathable the membrane, however large the vents, and however removable the thermal liner, they are still a little cumbersome and restrictive for a ride in the height of summer. However, just like riding in winter, choosing the right kit can make the difference between enjoying every moment and it feeling like a chore. And the prospect of a ride to the seaside for fish and chips is, frankly, one that few can resist. One of the best times to go riding is in the summer bright sunshine, warm weather and long hours of daylight make any ride even more fun. We state and discuss six conditions that encapsulate the claims of X-bar theory: LEXICALITY-each nonterminal is a projection of a preterminal SUCCESSION-each Xn + 1 dominates an Xn for all n ≥ 0 UNIFORMITY-all maximal projections have the same bar-level MAXIMALITY-all nonheads are maximal projections CENTRALITY-the start symbol is a maximal projection and OPTIONALITY-all and only nonheads are optional. In this paper we will demonstrate that a formalization of its content reveals very little substance in its claims. The most common job for specifiers is as the subjects of sentences, so we’ll look at those in another unit.X-bar theory is widely regarded as a substantive theory of phrase structure properties in natural languages. A specifier is a phrase that is sister to the bar-level and daughter to the phrase level. X-bar theory also proposes that phrase can have a specifier. In phrases like my sister, those shoes, and the weather, the determiner is a head that takes an NP complement. The other common place we see a head-complement relationship is between a determiner and a noun. Try to think of some other examples of verbs and prepositions that take noun phrases as their complements. The complement of the preposition is the noun phrase campus and the whole phrase is near campus. The head of this phrase is the preposition near, so the phrase is a preposition phrase. Here’s another example that has the same structure, but a different category. The NP coffee is sister to the verb head and daughter of the V-bar node so it is a complement of the verb. That head has the noun phrase coffee as its sister. Let’s look at some examples. Here we’ve got a verb phrase, with the verb drank as its head. The most common kinds of head-complement relationship we see are a verb taking an object or a preposition taking an object. If there’s a phrase in that position, it’s called the complement. A phrase might optionally have another phrase inside it in a position that is sister to the head and daughter to the bar level. We could have a noun phrase that consists of a single noun - Coffee? or Spiderman! We could have verb phrase that has nothing in it but a verb, like Stop! or Run! Or an adjective phrase might consist of only a single adjective, like Nice… or Excellent!īut X-bar theory proposes that phrases can have more in them than just ahead. If they’re optional, that means that it should be possible to have a phrase that consists of just a single head - and if we observe some grammaticality judgments, we can think of phrases and even whole sentences that seem to contain a head and nothing else. That’s to show that they’re optional - they might not necessarily be in every phrase. But you’ll notice in this diagram that these other two pieces, the specifier and the complement, which we haven’t talked about yet, are in parentheses. So if every phrase in every sentence in every language has this structure, then it must be the case that every phrase has a head. What about the middle level of the structure? Syntacticians love to give funny names to parts of the mental grammar, and this middle level of a phrase structure is called the bar level that’s where the theory gets its name: X-bar theory. So the bottom-most level of this structure is called the head level, and the top level is called the phrase level. And likewise, if the head is a preposition (P), then the phrase is a preposition phrase (PP), and Adjective Phrases (AP) have Adjectives as their heads. If the head is a verb (V) then the phrase is a verb phrase (VP). So if the head is a Noun, then our phrase is a Noun Phrase, abbreviated NP. Whatever category the head is determines the category of the phrase. The head is the terminal node of the phrase. Let’s look at it more closely. According to x-bar theory, every phrase has a head. Here’s a tree diagram that shows us that basic organization. X-bar theory makes the claim that every single phrase in every single sentence in the mental grammar of every single human language, has the same core organization. The theory of syntax that we’re working within this class is called X-bar theory. We saw in the last unit how we can use tree diagrams to show these relationships between words, phrases and sentences. We’ll see that within each sentence, our mental grammar groups words together into phrases and phrases into sentences. We’re starting to look at how our minds organize sentences. At the end of qualifying I had a pretty decent crash, but I was ok. Jed Beaton: “Today was another tough one. Finally, thank you to my team and thanks to all my fans as well who support me, it’s been a great GP for me.” My FC 450 is set up perfectly for me so now it’s just a case of continuing the progress we are making ahead of the next GP. Today was my second podium of the MXGP season and I felt strong in both races so I’m really happy with my riding at the moment. As a team we are always learning and improving and we are really going in the right direction as I’m now third in the championship standings, just four points down on second place. The progress that the team and I made this week has been fantastic and I leave Latvia with my best ever results, so I’m really happy. Rockstar Energy Husqvarna Factory Racing will next be in action at round six of the FIM Motocross World Championship on September 6.Īrminas Jasikonis: “It was a really great day and a great way to end the week in Latvia, with second overall. Narrowly missing out on the overall win, de Wolf maintains his fourth-place ranking in the championship standings and closes in on the leading riders. Thomas will now work on a full recovery ahead of round six of the MX2 World Championship.Ĭontinuing to impress in his debut season of EMX250 competition, Kay de Wolf recorded a pair of strong runner-up finishes in the two motos to earn second place overall. Suffering from the continuing effects of his recently fractured shoulder blade, the Danish racer elected to avoid worsening the injury. Going on to claim sixth position, Jed was rewarded with seventh overall and now sits in a strong fifth place in the MX2 World Championship.Īfter riding only a handful of laps during the morning’s free practice session, Thomas Kjer Olsen made the difficult decision to withdraw from racing in Kegums. Completing the first lap in fourth place, the 22-year-old briefly moved into third position before losing a few spots in the latter stages of the race. Coming up just short of the top 10 with an 11th-place finish, Jed was looking for a better result in moto two.Ī strong start in race two set Beaton up well. Beaton remounted his FC 250 quickly and embarked on a race-long battle through the field. A strong top-10 start put the Australian in a good place for a strong result until a small fall on the opening lap relegated him to 17th position. It was another frustrating opening MX2 race for Jed Beaton in Latvia. Disposing of Tim Gajser and Jorge Prado on his way to a strong third-place finish, Arminas claimed second overall and moves up to third position in the MXGP World Championship. Allowing the race to unfold while maintaining sixth position for the first half of the 30-minute-plus-two-lap moto, the Lithuanian then set his sights on the leading riders. Race two saw another strong start for Jasikonis as he again held a tight line around the opening corner. The 22-year-old then made the pass for second place on lap 11 of 17, eventually collecting a well-deserved runner-up finish. A great start saw the FC 450 rider carve a tight inside line around the first turn to emerge in fourth place, before moving into third on lap two. Lining up at the MXGP of Kegums following his confidence boosting race win at the previous round of the MXGP World Championship, Arminas Jasikonis made a great start to the fifth round of the series, earning a strong second-place result in the opening moto. In the MX2 division, Jed Beaton placed seventh overall after a challenging opening moto, before rebounding for a sixth-place finish in race two. A pair of strong starts and two calculated rides resulted in him claiming 2-3 finishes and with it moves up to third place in the MXGP championship standings. Rockstar Energy Husqvarna Factory Racing’s Arminas Jasikonis has continued his impressive run of form by claiming second overall at the MXGP of Kegums, a career-best result for the Lithuanian. |
