The importance of snow trousers is often overlooked. In fact, snow trousers are more important than snow clothes. Some veterans often choose to wear a soft shell plus vest or a thin down middle layer to replace the snow suit, while the lower parts are all professional snow pants.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/

　　Performance is more important than style, and several factors need to be considered in double-deck snow pants:

　　1. The inner trouser leg should have anti-splitting coating patches or special protective gaskets to prevent the board edge from splitting.

　　2. The lining is elastic, antibacterial and deodorizing.

　　3. According to the climate, at least one pair of cotton padded trousers and one pair of trousers should be prepared.

　　4. Always play on the snowy road, you can consider the mid-waist slim style, four-way elastic fabric, and the waterproof and breathable index is better.

　　5. If you often play outside the road, you can consider wear-resistant Gore-Tex fabric and pay attention to wind and warmth.

　　6. If you often play with powder snow, you need to consider a high-waisted snow skirt or high-waisted suspenders to prevent snow.

　　Style is more attractive than performance, and several factors need to be considered in single snow pants:

　　1. Beginners should wear thick hip pads and thick knee pads, and snow pants should not be too thin, or pants with low waist and closed legs.

　　2. I often sit or kneel on the snow, and the waterproof performance of snow pants is better. Consider fabrics that will not produce water stains.

　　3. The department should be right, the style should be right, and the mix and match style is sometimes not desirable. Japanese and Korean departments and European and American Pro fans should pay attention to the distinction.

　　4. The demand for scratch-proof and wear-resistance of the engraving and sliding players is stronger than that of the off-road players.

　　5. Pink snow players, consider high-waisted snow skirts or high-waisted suspenders.

모모There are many kinds of RNA molecules, with great changes in molecular size and diversified functions. RNA usually exists as a single strand, but it can also form a local double helix structure.So we can draw a preliminary conclusion, small molecules It is helpful to the needs of the industry market and social development. https://www.all-chemistry.com/

모모

모모1. Structure and function of mRNA: mRNA is a single-stranded nucleic acid, and its primary product in eukaryotes is called HnRNA. 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).

모모

모모2. Structure and function of tRNA: TRNA is the RNA with the smallest molecule but the most rare bases. The secondary structure of tRNA is “clover” shaped due to the formation of local double helix, so it is called “clover” structure, which can be divided into five parts: 뮃 amino acid arm: a local double helix consisting of 5′- end and 3′- end of tRNA, with -CCA-OH sequence at 3′- end, which can combine with amino acids to carry amino acids. 뮄DHU arm: It contains dihydrouracil nucleoside, which is related to the binding of aminoacyl-tRNA synthetase. 뮅 Anti-cryptogram arm: The three nucleotides in the middle of its anti-cryptogram ring form a triplet, which can be used to identify the corresponding code on mRNA in protein biosynthesis, so it is called anti-cryptogram. 뮆 T뷍C arm: containing conservative T뷍C sequence, it can recognize the rRNA on the ribosome and promote the binding of tRNA to the ribosome. 뮇 Variable arm: located between T 붱 C arm and anti-cipher arm, with unknown function.

모모3. Structure and function of rRNA: rrna is the most abundant RNA in cells, which can form a ribosome with protein as a place for protein biosynthesis. There are three kinds of rRNA in prokaryotes: 5S, 16S and 23S. There are four kinds of rRNA in eukaryotes: 5S, 5.8S, 18S and 28S.

　　Protein, the source of life, how much do you know? Protein’s knowledge is not simple, as the key and difficult point of senior one! Today, I will take you to find out and unlock the mystery of protein!for a long time Antibody Phage Display Service It has an extraordinary development speed, and I believe that the future will be as overwhelming as ever. https://www.alphalifetech.com/

　　Protein is the basic substance of cells and tissues. Without it, there would be no life. They are composed of amino acids, and through different sequences and structures, they form an ever-changing protein. This is like Lego of life. Every amino acid is a building block, which is combined to construct the diversity of life.

　　Protein has various functions, from structural support to catalytic reaction, from transporting substances to signal transmission, and they are indispensable roles in cells. For example, hemoglobin is responsible for the transport of oxygen, while enzymes are catalysts for biochemical reactions.

　　The synthesis process of protein is also very interesting. The process from transcription of DNA into mRNA to translation into protein is called the Central Rule. It reveals the flow direction of genetic information and is the key to understanding life phenomena.

　　The structure and function of protein are closely related. The primary structure is amino acid sequence, the secondary structure is partial folding, the tertiary structure is integral folding, and the quaternary structure is the combination of multiple subunits. These structural levels determine the function and stability of protein.

　　Protein is the cornerstone of life. To understand them is to understand the mystery of life. Through today’s study, I hope you can have a deeper understanding of protein and lay a solid foundation for senior high school biology!

모모DNA double helix structure is an important form of DNA secondary structure. It is a structural model put forward by Watson and Crick in 1953.Even so, inhibitors We must also adhere to the quality of the industry and create unique products for the company. https://www.all-chemistry.com/

모모

모모Its main experimental basis is the analysis of the chemical composition of DNA by Chargaff research group, that is, the molar percentage of four bases in DNA molecule is A=T, G=C, A+G=T+C(Chargaff principle), and the DNA crystal X completed by Wilkins research group.

모모

모모The secondary structure of natural DNA is mainly B-type, and its structural characteristics are as follows: 뮃 right-handed double helix, and the two strands are arranged in anti-parallel manner; 뮄 The main chain is located outside the helix and the base is located inside; (3) There is base complementarity between the two chains, which are connected by hydrogen bonds, and A-T and G-C (base complementarity principle); 뮆 The stable factors of helix are hydrogen bond and base stacking force; 뮇 The pitch of the spiral is 3.4nm and the diameter is 2nm.

　　Most protein is like a jumble of atoms packed together. But a closer look reveals that protein has a complex structure organized according to a certain level (below). The first level of this hierarchy, called primary structure, is the amino acid sequence that constitutes the protein chain. Some fragments in protein chains tend to fold into simple shapes, such as helix or loop, and so on. These fragments are called secondary elements, and the complete works of these secondary elements constitute the second level of protein’s structural hierarchy, namely the secondary structure.In addition to domestic, recombinant proteins It has also emerged in the international field and gradually gained the favor of more foreign friends. https://www.alphalifetech.com/

　　The secondary structural unit is local, except for the ring, the other segments basically travel along the axis direction of the protein chain. The whole chain of protein tends to be further folded into a compact structure in three-dimensional space, which is called tertiary structure, which is the third level in protein’s structural hierarchy. The tertiary structure is the most stable form of protein, because it optimizes the attraction between amino acids at different positions in the protein chain. Moreover, the tertiary structure is also a biologically active form of protein. If this form is destroyed, protein will lose some or all of its functions. Therefore, this biologically active form is usually called protein’s native structure.

　　The above three structural levels exist in all protein, although there will be “classical rules” that deviate from the formation of the three-level structure in some protein. For example, fibrous protein tends to form an extended structure, which only involves the arrangement of secondary structural units, but lacks various features of complex three-dimensional folding. Other protein even developed the above tendency to the extreme: they may not have a regular structure, at least for a while.

　　With the development of science and technology, smart phones have become an indispensable part of our lives. As one of the most intimate parts with us, the quality and performance of mobile phone screen have attracted more and more attention from consumers. Recently, Samsung has launched a mobile phone screen inquiry website called “OLED Finder”, which allows us to easily know what kind of mobile phone screen we have.among apple iphone screen manufacturer It has given great spiritual support to entrepreneurs, and more entrepreneurs will contribute to this industry in the future. https://www.lucentparts.com/

You can also turn off the push permission of the software in the application permission of the mobile phone.As an important brand soul of the company, mobile lcd touch screen Has outstanding performance, through the market test, still has a strong development trend. https://www.lucentparts.com/

　　2. If the phone is in the lock screen, it will also push hot information. At this time, you can find the software, then open the software settings and turn off the “lock screen reading switch”.

　　3. How to close the browser to recommend hot information: Open the browser, click the menu option in the upper right corner to expand the menu list, and click the Settings button. You can close the hot information through the settings in the settings interface. After entering the settings interface, click the navigation menu on the left and click Lab.

You can also set some other functions about the mobile phone desktop in this setting.

　　Although many manufacturers will claim how hard the screen is, in fact, every mobile phone user will face the problem of screen scratches. Many people will put a protective film on their mobile phone screens to protect them, which will not only cost money, but also affect the look and feel.In view of the actual needs of society, cell phone screen We need to change some original problems to better serve the society and benefit people. https://www.lucentparts.com/

　　If you don’t film it, there will be many scratches on the screen of the mobile phone soon. Although it generally does not affect the normal use, the experience is reduced to a certain extent, even when the second mobile phone is sold, it will affect the price.

　　According to the latest forecast of CCS Insight, a global technology research and consulting company, smartphone manufacturers will begin to produce smart phones with the function of self-repairing screen scratches within five years.

　　Ben Wood, chief analyst of CCS Insight, believes that this is not a story in science fiction, it can be done, and the biggest challenge is to set expectations for it correctly.

　　He also said: We are not talking about how the broken screen is restored. This is something that magic can do. What we are talking about is the self-repair of scratches on the screen surface, thus prolonging the service life of the equipment. “

　　The core of this technology is a brand-new material, which can cover the screen surface with a coating. Specifically, this coating is composed of a special material. When it is scratched, it will trigger a chemical reaction and produce a new material. When exposed to air, this new material will react and fill the defect, so that the scratch is repaired.

　　Wood finally pointed out that this technology needs further research and development, and interdisciplinary cooperation and innovative materials science are needed. Nevertheless, I still think it is possible to commercialize this technology in the next five years. “

　　In fact, various manufacturers have been studying the technology of self-repairing screens. In 2017, Motorola applied for a patent for a screen made of shape memory polymer; In 2019, Huawei also applied for a patent entitled “A method and equipment for repairing glass scratches”; Apple has also applied for a patent for a foldable iPhone, and its display can be repaired by itself when it is damaged.

　　When we choose a mobile phone, the screen quality is the first appeal of many users. As the only image export, mobile phone manufacturers are constantly iterating over the quality of the mobile phone panel every year. The selection of the mobile phone screen depends on the four parameters: resolution, refresh rate, touch sampling rate and screen material.The data shows that, phone lcd wholesale Its development potential should not be underestimated, and it is also the inevitability of its existence. https://www.lucentparts.com/

　　Resolution and refresh rate determine the visual effect.

　　At present, the screen pixels of the thousand yuan machine are basically 1080P+60Hz, and such an entry panel has been used for nearly ten years. At the price of 1,500 yuan, you can basically buy a screen with a high brush of 90Hz or 120Hz, while at the high end of 3,000 yuan or more, you can basically equip it with 2K resolution and refresh rates of 120Hz, 144Hz or even higher.

　　If we only look at the pixels, the resolution of 1080P is basically enough, and the resolution of 2K has more or less high requirements for the battery life of the mobile phone. Users have already failed to meet the screen with 60Hz refresh rate, and the high screen of 120Hz is gradually solving the cost problem. In recent years, the popularity of mid-range computers has basically been completed.

　　So simply use the price of mobile phones to popularize the corresponding panels:

　　1000-1500 yuan: 1080P+60Hz1500-2500 yuan: 1080P+90, 120Hz2500-3000 yuan: 2K+120Hz3000 yuan or more: 2K+144Hz or higher.

　　Gamers must watch: touch sampling rate

　　The sampling rate is more accurate to locate the finger on the screen of the mobile phone. When playing a game, the mobile phone with high sampling rate will also receive the finger instruction faster, thus being one step ahead of others in the game.

　　The hand sends various instructions to the mobile phone by sliding the screen. The higher the screen sampling rate, the higher the accuracy of the instructions, and there will be no broken touch. Generally, the screen with higher sampling rate has more obvious advantages in the game.

　　That is to say, the higher the touch sampling rate, the faster your reaction when you touch the screen during the game, and you will be able to throw skills earlier than other players, thus forming operations in the game faster.

　　Generally, the parameter of touch sampling rate will be introduced on the introduction page of mobile phone, and the higher this value is, the better. Generally, the touch sampling rate of game mobile phones is relatively high, and some manufacturers claim that their screens are “e-sports screens”, which is also relatively high. The instantaneous touch sampling rate generally exceeds 1000Hz.

　　Screen material determines the quality of imaging.

　　Finally, we talked about the screen material, which is the same as when we went to the home appliance market to buy a TV. When a variety of TVs are put together, you can easily compare which TV has better color and higher quality.

　　At present, the screen materials of mobile phones are basically TFT, LCD, AMOLED and Micro OLED.

　　TFT: currently used less, basically distributed in 100-yuan machines, with high power consumption, low sampling rate and poor hair color. It is facing the elimination of LCD, the main force of entry-level “cost-effective” mobile phones, with high penetration rate and low cost. AMOLED, which is developed from OLED, has high contrast, good hair color, power saving, refresh rate and other values, and high Micro OLED, which has high color gamut and fast response speed, but high cost and is generally very high.

　　Random screen materials from second to best, the choice of the above screen materials basically corresponds to the price of the mobile phone. Generally, the entry-level to mid-range models within 2,000 yuan are LCD screens, while the flagship model AMOLED is basically standard, and Micro OLED is the top screen ceiling.

　　For example, the whole iPhone12-14 uses OLED screens, while the previous iPhone11 used LCD screens. If you have friends around you who happen to be using these models, you can see the difference between them.
