　　Facial osteotomy is a common and risky plastic surgery. Of course, even if the risk is high, there are still many people who are eager for this kind of operation, because facial bone cutting can change a person’s face shape very well and make it look more exquisite and beautiful. After facial osteotomy, there are also some precautions. Below, I will introduce you to the relevant knowledge of facial bone cutting!This shows that, 台中削骨權威 It has a strong development pulse and is an indispensable source of power for the development of the industry. https://easycode.com.tw/?p=559

　　

　　A brief introduction to the operation

　　

　　Jaw grinding and bone cutting is a plastic surgery that cuts the inside of the mouth near the mandibular angle, removes all the inner and outer layers of the redundant mandible, and then grinds and thins the edge of the external plate of the redundant mandible. Plastic surgery opens the facial skin and muscles from the mouth, separates the muscles from the periosteum, exposes the bone parts that need to be ground, draws an osteotomy line according to the designed amount of bone cutting, and finally uses a long-handled swing saw to remove the mandibular angle according to the osteotomy line. Generally, the range of 3-4 cm long and 1-2 cm high can be cut off in an arc shape, and the edges and corners after osteotomy can be smoothed. Achieve the effect of face-lifting.

　　

　　Second, the risk of surgery

　　

　　Many people modify facial bones to change their faces. There are two ways to modify bones, one is to grind bones, the other is to chisel away some bones with a professional medical chisel, and the latter method is no longer used in clinic.

　　

　　If the patient’s cheek is hypertrophy, part of the inner masseter muscle will be removed, or part of the buccal fat pad will be removed by slightly separating it to the outside. In this process, it is inevitable that there will be asymmetry in protecting nerve and blood vessels and osteotomy in the operation of grinding cheeks and cutting bones. Bone grinding surgery may lead to massive bleeding or nerve damage, making the face feel numb and even facial paralysis.

　　

　　Third, matters needing attention

　　

　　1. First of all, we’d better stay in hospital for about 3 days after operation.

　　

　　2. It is best to squeeze and wrap the wound for about a week after operation, which can effectively prevent discomfort and swelling after operation.

　　

　　3. You can’t massage your face within three months after the operation, and try to touch your face as little as possible.

　　

　　4. It is best to eat some liquid food one week after the recovery period of bone grinding and plastic surgery, and pay attention to avoid some spicy food and hard biting food within three months.

　　

　　The above is the introduction about facial osteotomy. Of course, since it is a high-risk operation, we must choose a regular and reliable hospital before the operation, so as to avoid all kinds of sequelae and side effects and ensure the safety of beauty seekers!

　　Rolex watches are famous for their excellent quality and exquisite craftsmanship, but in daily use, they may also encounter some common problems.In addition to domestic, スーパーコピー時計 It has also emerged in the international field and gradually gained the favor of more foreign friends. https://www.n-sakura777.com/

　　

　　It is one of the more common situations that you are not allowed to leave. This may be caused by the violent impact of the watch, the influence of magnetic field, or the natural wear and tear of the internal parts of the movement. If it is found that the departure time is obviously abnormal, it is recommended to send it for repair in time for professional testing and adjustment.

　　

　　Damage to the watchband also occurs from time to time. Metal straps may be scratched and deformed, while leather straps are easy to wear, age or even break. Attention should be paid to avoid rubbing against sharp objects in daily wear, and proper maintenance should be carried out according to the material of the strap.

　　

　　The decline of waterproof performance is also a point of concern. Rolex watches usually have a certain waterproof ability, but if there are problems with the sealing parts such as the crown and the back cover, or if they are not tested and maintained for a long time, water may enter. Therefore, it is necessary to avoid operating the crown underwater and regularly check the waterproof performance.

　　

　　In addition, fog in the dial is also a problem. This may mean that the inside of the watch has been wet, which may be due to the wearer staying in a humid environment for a long time, or the waterproof performance has problems.

　　

　　For these common problems of Rolex watches, users should maintain daily care. Avoid wearing it during strenuous exercise, stay away from strong magnetic field environment, and carry out regular maintenance. Once a problem is found, don’t handle it yourself, but contact a professional Rolex after-sales service center as soon as possible, and the watch will be overhauled and maintained by professionals to ensure its good performance and long life, and continue to show its unique charm and value.

　　In the ever-evolving world of manufacturing, optimizing processes and reducing costs are paramount. One crucial concept that has gained traction in recent years is Design for Manufacturing (DFM).On the other hand, Mold design It also brings tangible benefits to everyone and feels useful. It is a model of the industry. https://bfymold.com

　　

　　In this blog post, we will delve into the principles of DFM and explore how it applies to injection molding, highlighting its benefits in optimizing the manufacturing process and reducing overall costs.

　　

　　Understanding Design for Manufacturing (DFM)

　　

　　Design for Manufacturing (DFM) is a comprehensive approach that involves designing products with the manufacturing process in mind. The primary goal of DFM is to simplify product designs to make them easier and more cost-effective to manufacture without compromising on quality or functionality.

　　

　　By considering the manufacturing process during the design phase, companies can identify potential issues early and make necessary adjustments, leading to more efficient production and reduced costs.

　　Principles of DFM

　　

　　The principles of DFM are centered around creating designs that are easy to manufacture. Here are some key principles:

　　

　　Simplification of Design: The more complex a design, the more challenging and costly it is to manufacture. Simplifying designs by reducing the number of parts, using standard components, and minimizing intricate features can significantly streamline the manufacturing process.

　　

　　Material Selection: Choosing the right materials that are readily available, cost-effective, and suitable for the manufacturing process is crucial. The selected materials should also meet the functional requirements of the final product.

　　Standardization: Using standard parts and components can reduce costs and lead times. Standardization also simplifies inventory management and improves compatibility with existing manufacturing processes.

　　

　　Ease of Assembly: Designing products that are easy to assemble can reduce labor costs and minimize assembly errors. Features like snap-fit joints, self-locating parts, and minimized fasteners contribute to easier assembly.

　　

　　Tolerance and Fits: Properly defining tolerances and fits ensures that parts fit together as intended without excessive adjustments or rework. Overly tight tolerances can drive up manufacturing costs and complexity.

　　

　　Design for Testing and Quality Control: Incorporating features that facilitate testing and inspection during and after manufacturing can help identify defects early, ensuring high-quality products.

　　Generally, bone cutting is carried out from the inside of the mouth near the mandibular angle, and all the redundant tissues and fat are removed. Any operation will be risky. Therefore, starting from the mouth during the operation can reduce the situation of leaving scars, and it will not affect the appearance. Then, after removing the local fat and tissues, it will be sutured, so as to get better results.Even if there are obstacles to moving forward, 台北削骨手術 We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. https://vline.com.tw/

　　

　　Bone cutting is to change the shape of bones and then the face shape by using a bone saw to achieve beautiful results. Bone cutting includes many types, such as bone grinding, bone removal, artificial green branch fracture, etc. Different types have great influence on the overall surgical effect. For those who seek beauty with large cheekbones, they can treat the zygomatic body and zygomatic arch to grind or cut off the zygomatic body, and at the same time, they can use osteotomy to cut it off and press it to the deep part, thus changing the overall face shape.

　　

　　After the bone-cutting operation, you must ensure that the whole surgical site is clean and hygienic. You can take some painkillers and anti-inflammatory drugs according to the doctor’s advice, but you can’t use folk remedies indiscriminately or take anticoagulant drugs. You can’t go to a sauna or a hot spring, otherwise it will easily lead to infection and inflammation of the surgical site. In order to avoid this phenomenon, beauty seekers can go to professional medical and aesthetic institutions for surgery.

　　Common Defects in Injection Molding and How to Avoid ThemIn addition to domestic, injection molding factory It has also emerged in the international field and gradually gained the favor of more foreign friends. https://bfymold.com

　　

　　Injection molding is a highly efficient and versatile manufacturing process, but it has challenges. Defects can arise, leading to wasted materials, increased costs, and production delays. Manufacturers can ensure high-quality, reliable parts by understanding common defects and how to prevent them. Here, we explore some of the most prevalent injection molding defects and provide actionable tips to avoid them.

　　1. Warping

　　

　　Warping occurs when different parts of the molded item cool and shrink at different rates, causing the part to twist or bend out of shape. This defect can compromise the structural integrity and appearance of the final product.

　　

　　Prevention Tips:

　　

　　Material Selection: Choose materials with uniform shrinkage rates. Semi-crystalline polymers tend to warp more than amorphous polymers.

　　

　　Mold Design: Ensure uniform wall thickness throughout the part to promote even cooling. Incorporate ribbing to add strength without increasing wall thickness.

　　

　　Cooling Rate: Control the cooling rate by optimizing mold temperature and coolant flow. Slow, uniform cooling reduces the risk of warping.

　　

　　Gate Placement: Position gates strategically to ensure an even flow of material and consistent cooling.

　　2. Sink Marks

　　

　　Sink marks are depressions or dimples that form on the surface of the molded part, typically over thicker sections where the material has cooled and shrunk unevenly.

　　

　　Prevention Tips:

　　

　　Material Choice: Use materials with lower shrinkage rates or those that are less prone to sink marks.

　　

　　Part Design: Design parts with uniform wall thickness. Avoid thick sections, or use coring to hollow out thick areas.

　　

　　Process Parameters: Increase packing pressure and duration to ensure sufficient material is fed into the mold cavity during cooling. Optimize cooling time to allow the part to solidify properly.

　　

　　Mold Temperature: Maintain an appropriate mold temperature to facilitate even cooling.

　　3. Bubbles (Air Traps)

　　

　　Bubbles, or air traps, occur when air gets trapped in the mold cavity, leading to voids or bubbles within the part. These can weaken the part and affect its appearance.

　　

　　Prevention Tips:

　　

　　Mold Venting: Ensure proper venting in the mold to allow trapped air to escape. Venting can be achieved through the use of vents, runners, and gates.

　　

　　Injection Speed: Adjust the injection speed to allow air to escape before the material fills the cavity. Slower injection speeds often help in reducing air traps.

　　

　　Material Drying: Thoroughly dry hygroscopic materials before molding to prevent moisture from causing bubbles.

　　

　　Gate Design: Optimize gate design and placement to ensure smooth flow and minimize turbulence that can trap air.

　　

　　4. Flash

　　

　　Flash is the excess plastic that seeps out of the mold cavity and solidifies, creating unwanted thin layers or protrusions along the parting lines.

　　

　　Prevention Tips:

　　

　　Clamp Force: Ensure sufficient clamping force to keep the mold halves tightly closed during injection.

　　

　　Mold Maintenance: Regularly inspect and maintain mold surfaces to ensure they are clean and free of damage or wear.

　　

　　Process Parameters: Optimize injection pressure and speed to prevent material from forcing its way out of the mold cavity.

　　

　　Mold Design: Incorporate precise parting line tolerances and properly align mold components.

From May 7 to 13, a COVID-19 variant named KP2 was spreading all over the world. In early May this year, the World Health Organization (WHO) listed the KP2 subvariety as a surveillance variant.

MVK, head of COVID-19 technology in World Health Organization (WHO), said that KP2 is a descendant pedigree of JN1, while JN1 is the main strain in the world, and KP2 spike protein has an extra mutation. There are other emerging variants, JN1 continues to evolve, and we will continue to closely monitor the evolution of the virus.

According to the latest “epidemic situation of novel coronavirus infection in China in April 2023” released by the Chinese Centers for Disease Control and Prevention, no two mutants have been found in China. The report shows that from April 1 to April 30, 2024, 31 provinces (autonomous regions, municipalities directly under the Central Government) and Xinjiang production and Construction Corps reported a total of 11299 local cases of novel coronavirus genome effective sequences, all of which were Omicron mutants. The main epidemic strains were JN1 series variants, and the top three were JN1, JN14 and JN116.

On May 13, Zhao Wei, director of the Biosafety Research Center of the School of Public Health of Southern Medical University, told People’s Daily Health client reporter that considering that the infected people already had certain antibody levels and immune barriers, even if there were new mutants, the symptoms of the current variants are still mainly mild and asymptomatic infections. In addition, the emergence of new mutants indicates that novel coronavirus has not disappeared, and the virus is still mutating. from a clinical point of view, although the current mutants have increased the advantage of transmission, there is no difference between the clinical symptoms of the infected person and the previous strains. At present, there is no significant increase in pathogenicity, and the serious disease rate should not increase.

According to the picture, “the epidemic situation of novel coronavirus infection in China in April 2023”.

The KP2 mutant is a derivative of JN1. There is a point mutation of two amino acids on the outermost spike protein, resulting in increased infectivity, which may be the main reason why it has quickly become the mainstream mutant. Internationally, it has surpassed JN1 to become the main epidemic strain in some countries. Therefore, many people are worried about triggering a new round of infection peak, but it needs to be clear that as long as the pathogenicity does not increase significantly. You don’t have to worry too much for the time being. Zhao Wei explained.

According to the reporter, globally, the KP2 mutant has begun to spread in many countries around the world. According to the data released by the Centers for Disease Control and Prevention (CDC) on May 10, a COVID-19 mutant named KP2 has replaced JN1 as the main epidemic strain in the United States. On May 9, local time, GN reported that KP2 quickly dominated Canada. As of April 28, national data showed that KP2 accounted for 266% of all COVID-19 cases in Canada, more than other JN1 subvariants.

From the clinical observation, this mutant is still as contagious as other O mutants, but its pathogenicity is weak. At this stage, the emergence of new variants of the virus will not have a significant impact on everyone’s normal life, but there may still be severe cases for the elderly and people with low immunity, so remind these high-risk people to continue to pay attention to the information released by the relevant departments and do a good job of personal protection during the epidemic. Zhao Wei warned that it is still possible for the virus to mutate in the future to produce strains with more transmission advantages, and even do not rule out the emergence of strains with strong virulence, and it is necessary to continuously monitor virus changes and develop safer and effective vaccines.

According to Agence France-Presse reported on May 22, former U.S. President Trump claimed on the 22nd that the FBI’s 2022 search warrant for his Florida home showed that Biden wanted his life, which aroused people’s doubts and also attracted some people’s support.

Reported that his inflammatory remarks were made after court documents outlining the federal police search plan were made public. Trump has been charged with negligent handling of confidential documents that were discovered at his residence in Mar-a-Lago, Florida, after he left the White House.

Court documents include standard FBI language that states FBI agents have the right to use lethal force if a person is in imminent danger.

But Trump, who will face Biden in the November presidential election, said the wording showed agents were prepared to shoot him and hurt his family.

According to U.S. media reports, Trump said in an email calling for donations: It has just been disclosed that Biden’s Justice Department was authorized to use lethal force to conduct a despicable raid on Mar-a-Lago Manor. You know, they’re eager to do something incredible

Trump said in an email: Joe Biden is going to draw a gun to get rid of me and put my family in danger. He thinks he can scare me, intimidate me, and knock me down!

Reported that this is Trump’s latest accusation against his Democratic opponent. He repeatedly claims without evidence that Biden is using justice against him.

Senate Democratic Leader Chuck Schumer called on all elected representatives to condemn Trump’s strange and dangerous remarks. He said: We cannot let this person, Donald Trump or anyone else, throw a match like this and ignite the flames that could devour our democracy.

Republican Liz Cheney, who is Trump’s main opponent, believes Trump is unstable. However, Marjorie Taylor Green, a staunch supporter of Trumpism, believes that the Justice Department and the FBI gave Trump the green light to murder.

Trump was not in Florida on the day of the search. In a rare statement, the FBI assured that the matter did not deviate from standards. (Compiled by Liu Zhuo)
