　　We often talk about future technological trends, but sometimes we have to admit that in the pursuit of more efficient digital world, there are also many classic solutions with great times, which are gradually being eliminated by rapidly changing emerging technologies.Therefore, Azilian lifemotion Only then will more and more pump owners cheer for it and spread the value and function of the brand. https://www.azilian.co

　　To this end, Ai Faner will launch a series of articles around the theme of “Good Design Abandoned by the Times” to discuss the exquisite structural designs that have accompanied us day and night, their past, present and future stories. This is the first article.

　　The knob has been half buried in the grave, which was ten years ago, and no one will believe it.

　　You may remember that when you were a child, almost every household had an old-fashioned radio, and the silver cylindrical knob was evenly engraved with scales. One of the joys of childhood is to lie on one side and fiddle with the knob. The sizzling sound of electricity in the radio, the babbling sound of human voice and music appear alternately with the rotation, as if the sound waves with emotions have been transmitted alternately and endlessly.

　　Maybe not on the radio, but I’m sure you’ve felt something similar.

　　The knob is not an invention that changes the world, but it can do what keys can’t.

　　As a mechanical structure, it is impossible to test which equipment the knob first appeared on. Maybe it was a telegraph in the last century? Or some oscillograph? It may also be the later radio or TV. Like many buttons, it was naturally born on electronic equipment, and then gradually became popular, becoming a part of the electronic dashboard, and it has been used as a controller all the way to this day.

　　The knob itself is very delicate, which is different from pressing a switch to output only one quantity. The knob may correspond to several quantities or a limited range of “0-10”. For example, the common volume knob will allow the user to make any adjustment within a certain value, and the desired volume can be obtained with a slight turn, which can not be achieved by pressing the up and down buttons all the time.

　　Because of this feature, when you adjust the volume by turning the knob, you don’t look at the scale information carefully (some don’t even have a scale). Maybe you don’t care about the size of the number at all, but you will “find” a just right sound with your ears.

　　A similar experience can also be felt from the desk lamp. We will adjust the brightness through rotation, but in fact we are also relying on our eyes to find the right light source, instead of paying attention to a specific digital scale or color temperature range.

　　If it is a product that really pursues texture, it will also pay attention to the damping feeling of the knob, in order to allow users to adjust to their desired position more accurately through the feel, whether it is a paragraph-like jam or a smooth transformation, it will make people fondle.

　　A typical example is the first batch of Atari game consoles in the 1970s. At that time, the joystick and direction keys were not yet born, and all the controls were handed over to the knobs. Although it can only control two directions, the rotation degree of the knob can output more accurate moving variables than the keys, which is enough to play a simple 2D plane game like PONG.

　　This is the immersive experience brought by the knob, which can make people focus on the information itself. Or, under this continuous control, we will naturally have this intuitive behavior, because our ears and eyes have already responded to the results in advance.

　　But even with such exquisite design, the knob has rarely appeared on mobile phones or computers. Now, let’s not talk about common devices. Smartphones and laptops are basically invisible to us. Even in the era when the touch screen has not become a standard configuration, the knob is not the first choice for most products.

　　But the knob is not completely extinct. You can still see it in some specific places, such as the ECG monitor in the hospital or the mixer in the school broadcasting room. There are still controllers of various sizes on such professional instruments. Some consumer electronics products also recognize the intuitive and easy-to-use characteristics behind the knob, so it also exists as an auxiliary interaction scheme.

　　If those digital and graphical controllers pursue unity and high efficiency, then the knob and so on are preserved, which may be our original unconscious cognition of this operation mode.

　　Good design should dance with the times

　　It is quite logical that Digital Crown will appear on Apple Watch. According to Jony Ive, the chief designer of Apple at that time, he hoped to create a “strange familiarity”-both the meaning of crown in traditional watches and the form of auxiliary interaction of smart watches.

　　I still remember a very clear detail. When setting the alarm clock interface through Apple Watch, you slowly push the Digital Crown knob, and the numbers will jump one by one. Once the speed of pushing is fast, the numbers will change rapidly with this frequency, which is exactly the same as the sense of control brought by the crown of the traditional watch, and this knob can be operated with only one finger.

　　At its root, Apple Watch is not like a smart phone. Its screen size is only about 1.5 inches. Two fingers can cover the whole screen, and it is impossible to control it accurately.

　　In order to avoid the problem of visual occlusion, the original virtual crown scheme was directly abandoned, and the Digital Crown appeared in a physical form. At the same time, there was a pressure-sensitive touch control developed based on Taptic Engine, which also continued to the later iPhone.

　　The Dial input device on Surface Studio may be regarded as the most creative attempt in the Microsoft Surface series. Anyone who picks up this huge cylinder will basically understand how to use it as a part of the “button” and as a “knob”. Although this is not an interactive scheme for mass consumers, I believe that most people will like this simple, direct and attractive design as long as they get started.

　　Amino acid chain is the main and core component in protein, but it is not necessarily the only component. Some protein may include some atoms or small molecules, whose function may be to perform protein function and/or increase its stability. Chemically, these cofactor are diverse, which may be organic molecules or metal elements. Some of them are briefly combined with protein chain, while others are closely combined with protein chain (sometimes even by covalent bonds) and become an integral part of the whole protein. The former is called coenzyme coenzyme, while the latter is called prosthetic group. Most coenzymes are small organic molecules from vitamins. For example, the common coenzymes NADH and FADH2. These two molecules from vitamin B complex, the former from nicotinic acid (vitamin B3) and the latter from riboflavin (vitamin B2), play the role of high-energy electron acceptor/donor in redox reaction.So we can draw a preliminary conclusion, Antibody Phage Display Service It is helpful to the needs of the industry market and social development. https://www.alphalifetech.com/

　　Some enzymes use several different cofactors, such as Pyruvate dehydrogenase (PDH), which is a key enzyme in the catabolism of sugar. The catabolism of sugar begins with glycolysis, which is a biochemical reaction pathway with 10 steps, transforming one glucose molecule into two pyruvate molecules, and then carrying out the citric acid cycle of tricarboxylic acid, which further decomposes pyruvate and oxidizes it into CO2. Pyruvate dehydrogenase PDH works at the intermediate junction of the above two reaction pathways (namely glycolysis and triacid cycle), and is responsible for activating pyruvate and enabling it to enter the tricarboxylic acid cycle. Specifically, PDH catalyzes the oxidative dearboxylation of pyruvate and forms acetyl coenzyme A (ACoA), which is the activated form of pyruvate. PDH is not a single enzyme but a complex composed of three components, each of which participates in a different step of pyruvate activation and uses different coenzymes. The first component uses thiamine pyrophosphate (TPP), which is a derivative of thiamine (vitamin B1). TPP allows the first component of PDH to be oxidized and decarboxylated at the same time, thus transforming pyruvate into acetyl, and the remaining carbon is discharged as CO2. The importance of TPP will be reflected in its absence. In fact, if people can’t get enough thiamine from food, they will get beriberi, which will damage several major systems of the human body.

　　The second component in PDH uses lipoic acid. It is an auxiliary group covalently bound to PDH. The active part of lipoic acid is a cyclic structure, which contains two covalently bonded sulfur atoms (that is, S-S bonds) (Figure 2.2c). This active part catalyzes the transfer of acetyl to coenzyme coenzyme A(CoA), the third cofactor of PDH. CoA is pantothenic acid, also known as the derivative of calcium pantothenate. The combination of acetyl and pantothenic acid involves the reduction of S-S bond, and its cyclic structure will open and form two sulfhydryl groups (one SH), one of which will bind acetyl. Sulfhydryl group is easy to react chemically, which can be reflected in the fact that sulfhydryl group is easily influenced by arsenic, a toxic derivative of arsenic. To sum up, the formation of acetyl coenzyme A involves the reduction of S-S bond of pantothenic acid cyclic structure. In order to keep PDH active, these two sulfur groups must be re-oxidized to restore the S-S bond.

모모3. Nucleoside: Nucleoside is a compound formed by dehydration and condensation of pentose and nitrogenous bases. Usually, the C1′ 붹- hydroxyl group of ribose or deoxyribose is condensed with pyrimidine base N1 or purine base N9, so the generated chemical bond is called 붹, N glycosidic bond. Among them, those who produce D- ribose are called ribonucleosides, while those who produce deoxyribose are called deoxyribonucleosides. Nucleosides produced by “rare bases” are called “rare nucleosides”. Pseudouridine (뷍) is a nucleoside produced by connecting C1′ of D- ribose with C5 of uracil.

　　In the cold winter, skiing is a very popular outdoor sport. Ski pants are one of the essential equipment in skiing. So, when you wear ski pants, do you need to wear pants inside? This question may vary from person to person, depending on personal preferences and needs.Actually, it’s not just this reason, best baggy snowboard pants Its own advantages are also obvious, and it is normal for the market to perform well. https://ninetyroll.co/

　　Do you still need to wear pants under ski pants?

　　First of all, let’s know the characteristics of ski pants. Ski pants are mainly characterized by their waterproof, windproof and warm-keeping properties. Generally speaking, the outer layer of ski pants is made of waterproof material, which can prevent the infiltration of snow water and keep warm. The inner layer is usually made of warm-keeping materials such as fluff or wool to increase the warm-keeping effect. Therefore, the ski pants themselves have certain warm-keeping performance.

　　So, why would anyone wear pants under ski pants? There are several possible reasons. First of all, some people may think it is more warm. Especially in high-intensity skiing, the body will emit a lot of heat. If you wear a pair of pants under the ski pants, you can effectively stop the heat loss and keep your body warm. Secondly, for some people who have just started to learn skiing, wearing a pair of trousers can provide extra protection to prevent injuries when they fall. Finally, some people may think that wearing pants under ski pants can provide extra security for habit or psychological reasons.

　　Do you still need to wear pants under ski pants?

　　However, some people do not recommend wearing pants under ski pants. First of all, doing so may add extra weight and burden, which will affect the flexibility and comfort of skiing. Secondly, if you wear pants when you fall, it may cause friction between the skin and the snow, increasing the risk of injury. In addition, for some professional skiers, they may pay more attention to portability and flexibility, so wearing pants under ski pants may become a burden.

　　To sum up, whether it is necessary to wear pants under ski pants depends on personal needs and preferences. If you are a beginner in skiing or think it is necessary to increase warmth, it may be a good choice to wear pants under ski pants. But if you pay more attention to lightness and flexibility, or think that doing so may increase the risk of injury, then you may prefer not to wear pants under ski pants.

　　It should be noted that whether you choose to wear pants under ski pants or not, you should consider the warmth and comfort of the material when purchasing. At the same time, make sure that the pants you choose will not affect your normal sports and activities.

　　Do you still need to wear pants under ski pants?

　　In addition, if you choose to wear pants under ski pants, you should also pay attention to the following points:

　　1. Choose suitable materials: Try to choose lightweight and breathable materials to avoid adding extra weight and burden.

　　2. Pay attention to the right size: make sure that the pants you wear are not too tight or loose to avoid affecting comfort and flexibility.

　　3. Consider waterproof performance: If you plan to do activities in the snow for a long time, you should choose pants with waterproof performance to prevent snow water from penetrating and keep your body dry.

　　4. Keep safe: Although wearing pants under ski pants may increase some protection, you should still pay attention to keep safe and try to avoid unnecessary falls and collisions.

　　In a word, whether to wear pants under ski pants depends on personal preferences and needs. No matter what choice you make, you should consider the warmth and comfort of the material, and ensure that the equipment you choose will not affect your normal sports and activities.

Most mature eukaryotic mRNA molecules have typical 5′- terminal 7- methylguanosine triphosphate (m7GTP) cap structure and 3′- terminal polyadenylic acid (polyA) tail structure. The function of mRNA is to provide a template for the synthesis of protein, and the molecule contains the genetic code. Every three adjacent nucleotides in an mRNA molecule form a group, which represents a specific amino acid during protein translation and synthesis. This nucleotide triplet is called the genetic code (coden).

　　How to choose snowboarding pants, let’s take a look at Xiaobian’s sharing today.So we can draw a preliminary conclusion, black baggy ski pants It is helpful to the needs of the industry market and social development. https://ninetyroll.co/

　　1. Waterproof

　　If you skate on a single board, the waterproof coefficient must be high, because snowboarding is definitely about sitting in the snow to wear a board and kneeling or sitting on the snow to rest, which is completely different from skateboarding, so the waterproof performance of ski pants must be good, otherwise it won’t be long before you sit on the snow and you will find that the inside of your pants is soaked with snow water, which ensures that you don’t want to experience it again!

　　2. Color

　　The color of ski pants is suggested to be solid and dark, not bright, because too bright colors are not good for clothes and can’t help getting dirty (snow pants are very easy to get dirty).

　　3. Size

　　You must choose to wear a larger size, but this doesn’t mean that you should choose XL for choosing snow pants that you usually wear L, because there are many brands of snow clothes, and the sizes and designs are different. Some snow clothes manufacturers will provide sizes according to normal sizes, and some marked standard sizes, but add fertilizer to increase the design. Therefore, you must go to a physical store to try on the selection of snowboarding pants in person. Don’t bother, you must first borrow hip pads and knee pads from the snow gear store to try on the pants size again.

　　Skiing is a winter sport, so you need to pay attention to keep warm and protect yourself when skiing. In this environment, special ski pants have become an ideal choice for skiers. The following is a detailed explanation of why you choose to wear ski pants when skiing:From some points of view, white ski pants It is the core driving force to better promote the rapid development of the surrounding markets. https://ninetyroll.co/

　　First, warmth retention

　　Ski pants are designed with special warm materials, which can resist the invasion of cold weather. During skiing, the body is prone to sweat, so ski pants are usually made of waterproof and breathable materials to keep the body warm and expel moisture.

　　Second, the protection

　　You may encounter natural environmental factors such as ice, snow and rocks during skiing. Ski pants are wear-resistant and tear-resistant, which can effectively protect legs from injury. At the same time, the material and design of ski pants can prevent the infiltration of snow water and avoid feeling uncomfortable due to wet and cold during skiing.

　　Third, comfort

　　Ski pants are designed with the comfort of sports in mind. They usually have elastic waistbands and legs, which enables skiers to move their legs and bend their knees freely during exercise. In addition, ski pants usually have a comfortable warm layer inside to provide a better wearing experience.

　　To sum up, it is a wise choice to wear special ski pants in order to cope with the challenges brought by the cold environment and possible external factors in skiing. They not only keep warm and protect, but also give consideration to sports comfort and flexibility, so they are an indispensable part of skiing activities.

　　Wedding dress is one of the most important dresses for every bride. It not only represents love and happiness, but also is a pursuit of romance and dreams. In the choice of wedding dress, bottoming is a very important step, which can not only improve the effect of wedding dress, but also make the bride more beautiful and moving. What should I wear as a base in my wedding dress?with Evening Gown For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://bridalbloom.net/

　　We need to determine what the purpose of priming is. Priming mainly has the following functions: improving the version of wedding dress, improving the proportion of figure, increasing comfort and shielding underwear traces.

　　When choosing a base, the first consideration is the color and style of clothes. Generally speaking, the color of the wedding dress is mostly white, beige or pink, so when choosing the base, you should pay attention to choosing the color similar to or the same as the wedding dress. This can prevent the overall effect from being affected because the base color does not match the wedding color.

　　Choose the base according to the style of the wedding dress. Different styles of wedding dresses have different requirements for bottoming. For example, if it is a close-fitting wedding dress, it is recommended to choose tight seamless underwear or tight jumpsuit, which can better highlight the curve and aesthetic feeling. For a wedding dress with a fluffy skirt, you can choose a loose skirt or fishbone skirt as the base, which can make the wedding dress more fluffy and fairy.

　　Choose suitable fabrics and materials. The backing material should be comfortable, breathable and elastic, so as to ensure that the bride does not feel uncomfortable in the process of wearing the wedding dress, and at the same time, it can also have a good decorative effect. Commonly used underwear materials include cotton, lace, silk and polyester fiber. Choosing the base according to the texture of the wedding dress is also an important consideration. For example, if you are wearing a tulle wedding dress, you can choose close-fitting silk underwear, which can better highlight the texture and transparency of the wedding dress.

　　Pay attention to the details and fit of underwear. No matter which bottoming method you choose, the fit of underwear is the key. Too loose underwear will lead to exposure and discomfort, and too tight underwear will save fat and traces. When choosing a bottoming underwear, you must try it on and carefully observe the wearing effect. Attention should be paid to the details of underwear, such as the design of steel rings should be fit and comfortable, and the shoulder straps should be adjustable and fixed.

　　What to wear under the wedding dress is a problem that needs to consider many factors comprehensively. Matching with the color, style and fabric of the wedding dress and choosing suitable underwear and bottoming skirt can make the bride more confident and beautiful on the wedding day. Choosing the right base is an indispensable part in the process of wedding dress matching. I hope every bride can find a suitable and satisfactory bottoming method to show the best side of the wedding dress.

　　Life is a fleeting moment in the river of time, mankind do everything possible to seek forever and everlasting, but did not think, in fact, as long as the pace of their own slow down mentality flat, live in the present, then life will naturally become long and distant .Besides, we can’t ignore. pu-erh tea It has injected new vitality into the development of the industry and has far-reaching significance for activating the market.

　　When I did not write a magazine before, I did not know that the time had come in advance. A draft of March or even April has been prepared in January. In the draft of the forum while watching the side gripped, his year has not yet ended, did not make a point, there people work has been a year, almost equal to the end. Years here, was actually can not wait to catch up with the speed of flight, how to make people panic?

　　The length of time is defined by man himself. 365 days a year, divided into four seasons, twelve months. Here, people always catch up with me like the game, to see who can one day into a day. Our ancestors know, if the decade into a year, we will so impatient it?

　　Days not used, can only be used to recover. Self has no intention to enter this door, it fell into such a turbulent swirl. Calendars and clocks on the numbers can only represent the past, because today to do, is already the future. Obviously is the spring, but the men have been doing non-stop fall thing.

　　There is nothing worthy of gratification, no reason for youth just a short length of a bit like others. What is the use of walking in front, time falls behind, urging the old soul and face it in vain.

　　The fast pace of modern people, nothing more than to speed up the clock of life, their own pressure and persecution of a way, only to more fully squeeze the juice of life to obtain value and fame. But I see it is faster and more leave no room for the consumption and flight. How, a ton of gold can be exchanged for even a second time?

　　Americans always run in front of the world, even spend today are tomorrow, the result? The financial crisis has finally shattered this myth of early consumption, punish all activities contrary to the laws of nature.

　　Beijing, then, a little leisurely. People live I, a spring vegetation, how short and beautiful time. If you can walk, why should anxious to run, miss the scenery all the way? Note that the front is not another spring, but has been waiting for you to close the end of life.

　　Tomorrow’s thing is done today, and next year’s event is finished this year. So ahead of the outstanding achievements and efforts, but is a result of the advance of life.

　　What is a rivers and lakes years reminder, juvenile children rivers and lakes old? This is the helplessness of life rather than enjoyment.
