　　Improper use of air conditioningIt is strictly required by such a standard, commercial air conditioner units? Only with today’s development scale, can we have the proud momentum to crush our competitors. https://puremind.com/product-category/puremind-air-conditioner/commercial-air-conditioner/

　　Not only will it increase electricity consumption,

　　It may even affect your health.

　　Today, follow the Shanghai Health Promotion Center.

　　Let’s learn the “cold knowledge” of air conditioning use ~

　　Don’t “open and close for a while”

　　I wonder if you have had such an experience?

　　Caught in the strange circle of air conditioning turning on cold and turning off hot, repeated operation is always “cutting suitable”; Or go out and get a courier, thinking that it is more energy-saving to turn off the air conditioner first.

　　In fact, often this behavior of frequently starting the air conditioner increases the power consumption and is not conducive to the maintenance of the air conditioner.

　　Studies have proved that air conditioning “turns on and off for a while” does not actually save electricity. Therefore, if you only go out for a short time, you don’t have to turn off the air conditioner and turn it on again.

　　Pay attention to “humidity” and “temperature”

　　The muggy air has a high humidity, so it is uncomfortable to adjust the temperature. At this time, try to turn on the “dehumidification mode” after air conditioning refrigeration, and the air will become more refreshing and comfortable.

　　If you need to stay in an air-conditioned room for a long time, remember to drink water properly to avoid the loss of water.

　　Practice has proved that it is most appropriate to control the indoor and outdoor temperature difference at 6-8≧, mainly to reduce the burden on the thermoregulation center and avoid the symptoms of dizziness, headache and dry skin and mucosa. Therefore, the air conditioning temperature is set at 26 to 28≧.

　　Don’t sweat and rush into the air-conditioned room.

　　In hot summer, it is easy to sweat when you move a little and bask in the sun. Do you just want to rush into the air-conditioned room? At this time, you should be careful that the disease will come to you.

　　For the general population, sudden cold and heat are easy to catch a cold, have a fever and have diarrhea; It is even more dangerous for patients with hypertension and coronary heart disease.

　　The cardiovascular system in the original thermal environment is in a state of relaxation, and the sudden cooling air after entering the air-conditioned room makes the blood vessels contract urgently, which is prone to dangerous situations such as myocardial infarction.

　　Therefore, don’t rush into the air-conditioned room after sweating, let the sweat collect first, or wipe your body with a dry towel first. When the air conditioner is just turned on, it should not be adjusted to a too low temperature, and at the same time, it should avoid cold air blowing directly on the head, neck and waist and abdomen.

　　Do a good job cleaning

　　The cleaning problem of air conditioning is often easily overlooked, and the bacteria hidden in it will take advantage of the opportunity to cause “air conditioning disease.”

　　Legionella, which lurks in the daily artificial water environment, is such a pathogen. Water contaminated by bacteria can be inhaled by human body in the form of aerosol. After people are infected with Legionella, there will be symptoms similar to pneumonia, such as high fever, chills, fatigue, muscle pain, etc., which may even be life-threatening.

　　The air conditioning system is the main “hiding point” of Legionella, so it is necessary to clean and disinfect the air conditioning; If it is a central air conditioner, the deposited cooling tower water should be replaced and the attached “dirty things” should be removed in time. Don’t forget to clean the casing and filter screen after the “air conditioning season”.

　　In addition, it is recommended to open the window for ventilation every 2-3 hours to ensure the cleanliness of indoor air.

According to a reporter from the head office, on May 22, local time, Norway and Spain respectively announced that they would formally recognize the Palestinian state on May 28. Ireland subsequently announced its formal recognition of the State of Palestine.

From mid-April to early May, Barbados, Jamaica, the Bahamas and other countries have announced the recognition of the State of Palestine. At this stage, nearly 150 countries have recognized the Palestinian State.

What does it mean that more and more countries recognize a Palestinian state?

Three European countries recognized the State of Palestine on the same day

Norwegian Prime Minister Stetler announced on May 22 that Norway will recognize a Palestinian state. Mr Stiller said the approval would take effect on May 28.

Subsequently, Spanish Prime Minister Sanchez announced that the country would recognize a Palestinian state on May 28. In addition, Irish Prime Minister Simon Harris also said that Ireland will formally recognize the Palestinian state.

Israel: recall Ambassador Palestine: welcome the decision of the three countries

After Norway and other three countries announced their recognition of the Palestinian state, Israeli Foreign Minister Katz immediately said that he would recall Israel’s ambassadors to Norway and Ireland. Katz said the move sent a clear message to Norway and Ireland that Israel would not remain silent.

It is reported that Israel has also recalled its ambassador to Spain, but the Israeli Foreign Ministry has not yet publicly confirmed the recall of the ambassador to Spain. Katz will also summon the ambassadors of the three European countries to Israel to condemn the three countries’ decision to recognize a Palestinian state. It is reported that Katz will show ambassadors a video of Israeli female soldiers being detained by Hamas militants.

Palestinian President Abbas issued a statement highly appreciating and welcoming the recognition of the Palestinian state by the three European countries on the same day. The statement said that the decision of the three countries is a salvation of the Palestinian-Israeli two-state solution, which urges all countries in the world to follow the example of Norway, Ireland and Spain to recognize the Palestinian state and support the realization of peace and stability on the basis of the two-state solution.

On the same day, the Palestinian Islamic Resistance Movement (Hamas) also issued a statement welcoming the initiative of the three European countries.

Recently, these countries have recognized the Palestinian state one after another.

On 19 April, Barbados announced its decision to formally recognize Palestine as a State.

On 22 April, the Ministry of Foreign Affairs of Jamaica issued a statement formally recognizing the State of Palestine.

On 2 May, Trinidad and Tobago decided at a cabinet meeting to formally recognize the State of Palestine.

On 7 May, the Ministry of Foreign Affairs of the Bahamas issued a statement that the Bahamas had decided to formally recognize the State of Palestine.

On May 10, the tenth emergency special session of the United Nations General Assembly adopted a resolution by a vote of 143 to 9, with 25 abstentions, determining that the State of Palestine was qualified as a member of the United Nations under the Charter of the United Nations and should be accepted as a member of the United Nations.

What does it mean for more and more countries to recognize a Palestinian state?

Qin Tian, Deputy Director of the Middle East Research Institute of the China Institute of Modern International Relations:

On 10 May, the tenth emergency special session of the United Nations General Assembly adopted a resolution by an overwhelming majority, affirming that the State of Palestine conforms to the membership of the United Nations as stipulated in the Charter of the United Nations and should be accepted as a member of the United Nations. This has put some pressure on some Western countries.

At the same time, Israel has stepped up its offensive against Rafah in southern Gaza, casting a shadow over the prospect of peace between Palestine and Israel. Under this pressure, countries that do not have too deep ties with Israel are the first to take the step of diplomatically recognizing a Palestinian state.

Although this is only the behavior of some countries, the impact is considerable, which exerts certain pressure on Israel, which is diplomatic and moral support beneficial to Palestine. It will also help the two sides to reach a Palestinian-Israeli peace settlement on a more equal basis in the future.

As the amount of smoke in electronic cigarettes increases with the use time£¬ the amount of smoke is gradually not as much as when it was first bought£¬ whether it is a box with large smoke or a small smoke product for replacing cigarettes. So why does this happen?To some extent, GeekBarVape Our development has surpassed many peer businesses, but it has never stopped moving forward. https://www.geek-bar-vape.us/

Today£¬ Wanyan.com will tell you the reason and how to solve these problems.

Question 1: The smoke is very small not long after it was used

Cause analysis:

The reason why the smoke becomes smaller rapidly in a short period of time is mostly the quality problem of electronic cigarettes.

For example£¬ when electronic cigarettes are produced£¬ heating wires with excessive resistance are used to *** the atomizer£¬ or the quality of the guide cotton is unqualified£¬ resulting in poor oil conduction£¬ and the quality of the battery core may be poor.

Solution:

The above problems are caused by product quality£¬ so once purchased£¬ they cannot be adjusted and solved by themselves£¬ and can only be returned. So we must recognize the big brands before purchasing£¬ at least there will be guarantees if there are brands.

Problem 2: After using it for a while£¬ the smoke produced has obviously decreased

Cause analysis:

1. Most mechanical rod box products with large smoke have blocked atomizers£¬ carbonized guide cotton£¬ and burned£¬ etc.

2. Most small smoke products have broken atomizers£¬ which leads to a significant weakening of the atomization effect or even failure to work£»

Solution:

1. Clean the atomizer£¬ try to use warm and clean water£¬ and dry it with a hair dryer or dry it naturally after washing£»

2. Because the atomizers of small smoke are usually integrated and cannot be disassembled£¬ the service life is usually 10-15 days. Therefore£¬ if you encounter such a situation£¬ you can directly buy a new atomizer£¬ which is generally not expensive.

Problem 3: No smoke due to wrong parameters

Cause analysis: The resistance value of the atomizer and the battery voltage parameters are not correct£¬ resulting in the battery being unable to provide enough voltage for the atomizer to work.

Solution: Replace the battery or atomizer to match the parameters.

Question 4: The smoke becomes smaller after changing the e-liquid

Cause analysis: It may be that the e-liquid with a lower VG content is used. VG (commonly known as vegetable glycerin) is one of the necessary ingredients of e-cigarette e-liquid£¬ and its main function is to produce smoke. Therefore£¬ if the e-liquid with a lower VG content is replaced£¬ the smoke will be reduced.

Solution: When purchasing e-liquid£¬ carefully check the product description or ask the seller about the VG content of the e-liquid. If you want more smoke£¬ buy one with a higher VG content. If you want less smoke£¬ buy one with a lower VG content.

　　What is High Frequency (HF) PCB?In order to facilitate users to have a better experience, FLEX PCB Many attempts have been made to upgrade the products, and the results are also very good, and the market performance tends to be in a good state. https://www.wellcircuits.com/

　　High Frequency PCB

　　In today¨s technological landscape, high-frequency electronic devices are becoming increasingly essential, particularly in wireless networks. The rapid growth of satellite communications and the shift toward high-speed, high-frequency information products demand the use of high-frequency substrates. Devices like satellite systems, mobile phone base stations, and other communication products require high-frequency PCBs for optimal performance.

　　Key Features of High Frequency PCBs

　　High Frequency PCB Features

　　The dielectric constant (DK) should be small and stable, with lower values minimizing signal delay.

　　The dissipation factor (DF) should also be low to ensure high-quality signal transmission, reducing signal loss.

　　Thermal expansion properties should be matched with the copper foil to prevent separation due to temperature variations.

　　Water absorption must be low, as higher absorption can negatively impact the dielectric constant (DK) and dissipation factor (DF) in humid environments.

　　The material must exhibit excellent heat resistance, chemical resistance, impact endurance, and peel strength.

　　Materials Used in High-Frequency Circuit Boards

　　Materials for High Frequency PCBs

　　High-frequency PCBs for wireless applications and high-speed data transmission, especially those in the GHz range, require specific material properties:

　　Adapted permittivity (dielectric constant).

　　Low attenuation to ensure efficient signal transmission.

　　Homogeneous construction with low tolerances in insulation thickness and dielectric constant.

　　Typically, high-frequency is defined as frequencies above 1 GHz. Currently, PTFE (polytetrafluoroethylene), commonly known as Teflon, is widely used for high-frequency PCBs, especially those operating above 5 GHz. FR4 and PPO substrates are commonly used for frequencies between 1 GHz and 10 GHz. The differences between these materials are as follows:

　　Regarding laminate cost, FR4 is the least expensive, while Teflon is the most costly. In terms of dielectric constant (DK), dissipation factor (DF), water absorption, and frequency characteristics, Teflon outperforms the other substrates. For applications requiring frequencies above 10 GHz, Teflon is the optimal choice, despite its higher cost and poorer heat resistance properties. To enhance the thermal and mechanical properties of PTFE, fillers like SiO2 or fiberglass are added. Additionally, because PTFE has molecular inertia and doesn¨t easily bond with copper foil, special surface treatments (such as chemical or plasma etching) are used to improve adhesion, though these may affect the dielectric performance.

According to a report by the Russian newspaper on March 14, Russian President Vladimir Putin delivered a speech to Russians, calling on them to vote in the three-day presidential election that began on the 15th. He pointed out that the election results will directly affect the country’s development in the next few years.

Putin said: I would bluntly say that participating in elections now is a manifestation of patriotism.

Putin said that the only source of power in Russia is the people, so only Russian citizens can determine the destiny of the motherland.

He said: What you have to do is not only vote, but also firmly express your will and desire and show that you will personally participate in the further development of Russia, because the election is a step towards the future.

He emphasized that during this difficult period, Russia is facing complex challenges in various fields. In order to overcome all these difficulties, the Russian people must be united and confident.

Putin also pointed out that soldiers on the front line will also vote, who have shown courage and heroism in the process of defending the motherland. They participated in elections and set an example for everyone.

Russia is scheduled to hold presidential elections from March 15 to 17, and the president-elect will take office on May 7. The term of office of the head of state is 6 years. If no candidate obtains a majority of the votes cast by voters voting, a second round of voting will be held 21 days later for the two candidates who obtained the most votes.

　　In recent years, the environmental sensor technology has made a significant breakthrough. The accuracy, stability and reliability of the sensor have been continuously improved, and the data acquisition and processing capabilities have also been significantly improved. However, with the increasing complexity and diversification of environmental problems, sensor technology still faces many challenges.Industry experts have said that, Optical rain detector It is very possible to develop and expand, which can be well seen from its previous data reports. https://www.codasensor.com/news-rain-sensor.html

　　On the one hand, environmental sensors need to adapt to various complex environmental conditions. For example, in extreme weather conditions, sensors need to maintain high accuracy and stability; In the heavily polluted environment, the sensor needs to have anti-interference ability and self-cleaning function.

　　On the other hand, with the rapid development of Internet of Things technology, sensors need to achieve more efficient data transmission and smarter data processing. This requires the sensor to have stronger computing power and lower power consumption to meet the needs of large-scale deployment and long-term operation.
