In addition to these aspects, fake diploma The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://diplomasreplacement.com/

According to a report by the Russian News Agency on July 15, Vladimir Talabrin, Russia’s Permanent Representative to the Organization for the Prohibition of Chemical Weapons and Russian Ambassador to the Netherlands, told reporters on the 15th that Western countries intend to accuse Moscow of using chemical weapons.

Talabrin reportedly said: Yes, they are working hard to do the work of the Technical Secretariat of the Organization for the Prohibition of Chemical Weapons to force it to take some steps intended to accuse Russia of using chemical weapons.

He said that Russia is fighting back against this in every possible way, trying to prove with concrete facts that all these efforts are futile.

Talabrin said that Russia does not and cannot pose a chemical weapons threat to Ukraine. He pointed out that Moscow does not rule out inviting experts from the Organization for the Prohibition of Chemical Weapons to study evidence of Kiev’s use of such weapons.

The 106th session of the Executive Council of the Organization for the Prohibition of Chemical Weapons was held in The Hague from July 9 to 12. Talabrin said after the meeting that Ukraine blatantly violated the convention and used military poisons against Russian troops, a point that many foreign experts and agencies have talked about. They noted that Ukraine’s armed forces were actively using drones to transport toxic chemicals. In addition, the United States, which supplied these substances to Kiev, is also violating the convention.

Lieutenant General Igor Kirilov, commander of the Radiation, Chemical and Biological Protection Forces of the Russian Armed Forces, said at a press conference that Kiev frequently violated the Chemical Weapons Convention. At the same time, the Organization for the Prohibition of Chemical Weapons, which was supposed to oversee the implementation of the convention, is now completely controlled by the West, which uses the organization to settle political scores with Russia.

Beijing, March 21 / PRNewswire-Asianet /– title: expose the lies and conspiracies of the Marcos government on the Huangyan Island issue

Reporter Liu Zan

Recently, the government of Marcos in the Philippines has continued to provoke trouble on the South China Sea issue, including on Huangyan Island in China’s Zhongsha Islands. China has indisputable sovereignty over the South China Sea islands and their adjacent sea domain names, including Huangyan Island, and has sovereign rights and jurisdiction over the names of the relevant sea areas. The Marcos government’s claim of sovereignty over Huangyan Island is purely vexatious, and it is a backlash to discredit China on issues related to Huangyan Island and the South China Sea. Relying on provocative forces outside the domain name to stir up trouble on the South China Sea issue will only undermine regional peace and stability and lack the support of regional countries.

Vexatious plot to encroach on islands and reefs

Foreign Ministry spokesman Mao Ning said at a regular press conference on the 5th that the Philippine Senate passed the so-called maritime zone domain name bill in a vain attempt to solidify the illegal award in the South China Sea arbitration case in the form of domestic legislation, illegally including the names of most islands and reefs and related sea areas in China’s Huangyan Island and Nansha Islands into their maritime area domain names, seriously infringing upon China’s territorial sovereignty and maritime rights and interests in the South China Sea. The Chinese side firmly opposes this and has made solemn representations to the Philippines.

Since the beginning of this year, the Philippine Marcos government has been constantly provocative on Huangyan Island. On January 28, four Philippine personnel illegally intruded into the reef disk of Huangyan Island; from February 2 to 9, the Philippine Coast Police vessel 9701 illegally intruded into the domain name of the sea adjacent to Huangyan Island; on February 15, the Philippine Fisheries and Aquatic Resources Bureau 3005 vessel illegally intruded into the sea domain name adjacent to Huangyan Island; from 22 to 23 February, the Philippine Fisheries and Aquatic Resources Bureau 3002 vessel illegally intruded into the sea domain name adjacent to Huangyan Island. In these intrusive activities, Philippine vessels ignored the dissuasion and warnings of Chinese coast guard vessels, and when the warnings were invalid many times, the Chinese coast guard vessels took necessary measures to drive away Philippine vessels in accordance with the law, such as forcing outside the prison and route control. on-site operation is professional, legitimate, and rational and restrained.

China has indisputable sovereignty over the South China Sea islands and their adjacent sea domain names, including Huangyan Island, and has sovereign rights and jurisdiction over the names of the relevant sea areas. These sovereignty and rights and interests are formed in the long-term historical practice and have sufficient historical and legal basis. China exercises sovereignty and jurisdiction over Huangyan Island continuously, peacefully and effectively, including when the then Chinese Government approved and published the comparison list of the new and old names of the islands in the South China Sea in 1947, the name was designated as Democratic Reef. When New China announced some place names of the islands in the South China Sea in 1983, the standard name was Huangyan Island.

The territorial scope of the Philippines is determined by a series of international treaties, such as the 1898 Treaty of Peace between the United States and Spain, the Treaty on the cession of the Outer Islands of the Philippines in 1900, and the Treaty on the Boundary between British North Borneo and the Philippines in 1930. The South China Sea islands, including Huangyan Island, have never been part of the territory of the Philippines. Before 1997, the Philippines never challenged that Huangyan Island belonged to China and never made a territorial claim to Huangyan Island.

In April 2012, the government of Aquino III of the Philippines sent warships into the sea domain name near Huangyan Island, illegally arrested Chinese fishermen and fishing boats and inflicted serious inhumane treatment, deliberately provoking the Huangyan Island incident. Aquino III government launched the South China Sea arbitration case in 2013 and tried to deny China’s territorial sovereignty and maritime rights and interests in the South China Sea with the so-called arbitration results in 2016. However, territorial disputes do not fall within the adjustment scope of the United Nations Convention on the Law of the Sea, and maritime delimitation disputes have also been excluded by China’s relevant declaration made in accordance with the Convention in 2006. The Philippine side’s move is a malicious abuse of the dispute settlement mechanism of the Convention and a violation of international law, including the United Nations Convention on the Law of the Sea. The so-called arbitration ultra vires trial, perverts the law judgment, the so-called award is illegal and invalid.

Rumors and hype try to discredit China.

In order to discredit China, the Marcos government made up lies. Nazario Brigera, a spokesman for the Philippine Fisheries and Aquatic Resources Bureau, said on February 17 that Chinese fishermen used cyanide to fish on Huangyan Island and deliberately damaged local fishing grounds to prevent Filipino fishermen from fishing in the area’s domain name. However, Tariela, a spokesman for the Philippine Coast Guard, admitted to the Philippine media that the Philippines did not have any investigation or evidence to prove that Chinese or Vietnamese fishermen used cyanide fishing on Huangyan Island.

China attaches great importance to the protection of ecological and fishery resources in the South China Sea. China has implemented a summer fishing moratorium in the South China Sea since 1999, according to the White Paper “China insists on resolving disputes between China and the Philippines through negotiations” issued by the Chinese government in 2016. By the end of 2015, China had established six national aquatic nature reserves, six provincial aquatic nature reserves with a total area of 2.69 million hectares, and seven national aquatic germplasm reserves with a total area of 1.28 million hectares in the South China Sea.

The so-called environmental problem is just one of the tactics used by the Marcos government to discredit China. The Philippine side has tried every means to portray China as a bully in the South China Sea and dress itself up as a weak person who has been oppressed in an attempt to mislead international public opinion and put pressure on China.

Recently, Philippine ships often take reporters to report and hype when they invade Chinese islands and reefs, calling the reasonable and legitimate law enforcement measures of the Chinese coast police violent eviction. The British Radio has reported that allowing reporters to film close contact between Chinese and Philippine ships is part of a deliberate strategy by the Philippine government to draw attention to China’s brute force.

In fact, China has been committed to resolving the South China Sea issue through dialogue and negotiations. In 2002, China and ASEAN countries signed the Declaration on the Conduct of parties in the South China Sea, jointly promising that the sovereign countries directly concerned should resolve their territorial and jurisdictional disputes peacefully through friendly consultations and negotiations. In recent years, China and ASEAN countries have actively promoted consultations on a code of conduct in the South China Sea. On the other hand, the Philippine side reneged on its commitments in the “Declaration” and a series of bilateral documents with the Chinese side, insisted on invading Chinese islands and reefs, and deliberately rammed the Chinese coast guard ship in defiance of dissuasion and warning, and what it did can be called a modern story of farmers and snakes.

Maintaining the stability of the South China Sea is in line with the national interests of the region

The Asia-Pacific region is the most dynamic zone of the global economy, and maintaining the stability and prosperity of this region is not only in the national interests of the region, but also conducive to global economic development. The Marcos government relies on forces outside the domain name to deliberately infringe, provocation and smear the South China Sea. Some countries outside the domain name continue to encourage and support Philippine actions based on their own geopolitical interests, aggravating tensions in the South China Sea and seriously endangering regional peace and stability.

Recently, Malaysian Prime Minister Anwar has repeatedly criticized the West for inciting fear of China. Anwar also said that there is no problem between Malaysia and China, and Western countries should not hinder the development of friendly relations between Malaysia and its important neighbor China.

Anwar’s statement reflects the common aspirations of most countries in the region for peace, development and unwillingness to take sides. Weng Desheng, a political commentator in Singapore, said that the economic development of ASEAN countries benefits from the hard-won peaceful and stable environment, and all countries should strive to maintain such an environment, and dialogue and negotiation is the best way to deal with the South China Sea issue.

Anna, deputy director of the Philippine Asian Century Strategic Research Institute, pointed out that interference by forces outside the domain name is an important reason for increased tensions in the South China Sea, which not only complicates the South China Sea issue, but also undermines the unity of relevant countries in dealing with the South China Sea issue. Forces outside the domain name should stop using the Philippines as a pawn and agent for strategic competition with China, and the Philippines should not be used by external forces.

United Nations, July 16 (Reporter Wang Jiangang) Fu Cong, Chinese Permanent Representative to the United Nations, spoke at the Security Council’s open debate on international order and multilateral cooperation on the 16th, calling on the international community to promote the construction of a more just and reasonable international order, safeguard sovereign equality, and Let every country find its place in the multipolar system, play its due role, and jointly promote an equal and orderly world multipolarization.

Fu Cong said that countries should respect each other, take into account each other’s core interests and major concerns, respect the development paths and institutional models independently chosen by the people of all countries, and not interfere in other countries ‘internal affairs; create common security, be based on the objective law that security is indivisible, and adhere to Resolve disputes through dialogue, resolve differences through consultation, and build a more balanced, effective and sustainable security architecture; Promote common development, promote inclusive economic globalization, accelerate the implementation of the 2030 Agenda for Sustainable Development, and strive to achieve the goal of leaving no country or anyone behind.

Fu Cong called on all countries to uphold fairness and justice, safeguard the authority of the United Nations and international law, advocate a global governance concept of extensive consultation, joint contribution and shared benefits, enhance the representation and voice of developing countries; demonstrate openness and inclusiveness, promote equal dialogue, exchanges and mutual learning among different civilizations, promote mutual understanding among people of all countries, and promote common values for all mankind.

Fu Cong pointed out that the real intention of some countries in the so-called rules-based international order is to create an alternative system outside the existing international legal system and seek legitimacy for double standards and exceptionalism. There is only one order in the world, that is, an international order based on international law. There is only one set of rules, that is, the basic norms of international relations based on the purposes and principles of the United Nations Charter.

Fu Cong said that NATO, as a well-known regional military group left over from the Cold War, seeks to expand its sphere of influence, is keen to create false narratives, add fuel everywhere, incite camp confrontation, and even blame and blame domain name foreigners on the Ukraine issue. This runs counter to the international community’s efforts to promote peace and talks. History has fully proved that wherever NATO’s black hands extend, turmoil and chaos appear. China advises NATO and some countries to reflect on themselves and stop being troublemakers who harm others and undermine common security.

Fu Cong said that common development and common security complement each other and are the foundation of a good international order, in which development is the overall key to solving all problems. Some countries generalize the concept of national security, build small courtyards and high walls, impose indiscriminate unilateral sanctions, and disrupt the global production and supply chain, which will ultimately lead to a situation of double lose and multiple lose. The international community must resolutely resist this erroneous practice.

Fu Cong said that Chinese leaders followed the trend of the times and proposed the Five Principles of Peaceful Coexistence, which fully reflected the spirit of the Charter and created the basic norms of international relations that countries, big or small, strong or weak, regardless of East and West, should respect each other and treat each other as equals., also provides an important ideological foundation for promoting the development of the international order in a more just and reasonable direction. Chinese leaders ‘proposal to build a community with a shared future for mankind is an inheritance and promotion of the purposes and principles of the United Nations Charter and the Five Principles of Peaceful Coexistence under the new situation.

　　The main factors affecting the price of marine diesel generators include the following aspects. I hope the following introduction can bring reference to users.Even if there are obstacles to moving forward, Gasoline vehicle generator 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://usrpower.com/product-category/vehicle-generators/gasoline-vehicle-generator-car-generators/

　　First, the brand affects the price of marine diesel generators

　　Brand is one of the key factors affecting the price of marine diesel generators. By virtue of its technology, manufacturing process and good market reputation, brand-name generator sets have good quality and stable performance, so the price is relatively high.

　　Power is another important factor that determines the price of marine diesel generators. Under the same brand and specification, the higher the power, the higher the manufacturing cost and technical requirements, so the higher the price. At the same time, different power units are suitable for ships of different sizes and different electricity demand, so choosing the appropriate power is also the key to control the cost.

　　Third, the configuration affects the price of marine diesel generators

　　The configuration of marine diesel generator will also affect its price. In addition to the standard configuration, there are some optional accessories, such as sound insulation box, rain shelter, mobile trailer, automatic control system and so on. The increase of these configurations will improve the performance and experience of the unit, but it will also increase the cost accordingly. Therefore, when choosing the configuration, we need to make a trade-off according to the actual needs.

　　Fourth, raw material prices

　　The price of raw materials is also one of the important factors that affect the cost of marine diesel generators. The price fluctuation of raw materials such as steel and copper will directly affect the manufacturing cost of generator sets, and then affect their market prices. Therefore, it is necessary to pay attention to the dynamics of the raw material market and its impact on the price when purchasing.

　　V. Seasonal demand

　　Seasonal demand will also affect the price of marine diesel generators. In the peak demand season, due to tight market supply, prices may rise; In the off-season, due to fierce market competition, prices may fall. Therefore, it is necessary to pay attention to the changes in market demand and its impact on prices when purchasing.

　　To sum up, the price of marine diesel generators is influenced by many factors such as brand, power, configuration, raw material price and seasonal demand. When purchasing, we need to weigh and choose according to the actual demand in order to find a product with high cost performance.

China-Singapore, Beijing, July 16 (Reporter Sun Zifa) Springer Nature’s professional academic journal “Nature Astronomy” recently published a planetary science paper saying that researchers have discovered a potentially accessible underground tunnel originating from an open pit on the moon. Evidence of tunnel. The results of this study have enhanced people’s understanding of lunar geology and may become an ideal location for a lunar base, thus potentially serving as a refuge in future manned missions on the lunar surface.

The paper said that more than 200 craters known as skylights have been discovered on the lunar surface, some of which were formed after the collapse of underground lava tubes. Accessible lava tubes or channels may provide a warmer environment than the lunar surface, but it has previously been uncertain whether they can lead to large underground caves.

In this study, co-authors of the paper, LC and LB of the University of Trento in Italy, and collaborators, analyzed radar data from the Lunar Reconnaissance Orbiter and found that radar brightness on the west side of the crater increased. Jinghai Crater is the deepest known crater on the moon, with a radius of approximately 100 meters, with vertical or overhanging walls and a sloping bottom.

The authors of the paper used radar images to conduct simulations and found that these observations could be explained by the presence of a cave void or pipe spreading from the west side of the bottom of the pit. They estimate that the pipeline is located at a depth of 130-170 meters, 30-80 meters long and about 45 meters wide. The cave may be flat or inclined at an angle of up to 45 degrees and may be accessible.

The authors concluded that the pipes or channels discovered in this study may be a common feature under the lunar plains, and that the Jinghai Pit and its channels may be an ideal site for a potential lunar base. The method used in the study may also be suitable for evaluating and characterizing other lunar craters to discover more channels.

Athens, May 13 (Reporter Chen Gang) Greek Prime Minister Mitsotakis criticized on the 13th that the new President of North Macedonia Davkova’s use of Macedonia when mentioning the name of the country in his inaugural speech was inconsistent with the previous agreement reached between the two countries.

North Macedonia President-elect Davkova was sworn in on the 12th. In her inaugural speech, she used Macedonia when referring to her country’s name, causing Greek Foreign Minister Jera Petritis to leave the table on the spot.

Mizotakis said North Macedonia’s new president’s call of his name was unacceptable, violating the agreement between the two countries.

The Office of the President of North Macedonia later issued a statement saying that Davkova insisted that she had the right to use the name of Macedonia and believed that her practice was in line with European values and principles.

European Commission President Von der Leyen and European Council President Michel successively issued articles on social media pointing out Davkova’s actions were inappropriate. Von der Leyen said on social media: If North Macedonia wants to successfully join the EU, the most important thing is to continue on the path of reform and fully respect binding agreements.

Macedonia became independent from Yugoslavia in 1991 and established its constitutional name as the Republic of Macedonia. Greece believes that this name implies that it has territorial and cultural heritage requirements for the Greek province of Macedonia. Due to a name dispute, Greece, a member of the European Union and NATO, opposes the Republic of Macedonia’s accession to the European Union and NATO.

After years of mediation negotiations, the two countries reached an agreement in June 2018 to change Macedonia’s name to the Republic of North Macedonia as a condition for Greece to agree to its accession to the European Union and NATO. In January 2019, the two parliaments successively approved the agreement. In February 2019, Macedonia officially changed its name to the Republic of North Macedonia.

　　When marine diesel generator sets drain water tanks in winter, the following key points should be paid attention to. For example, pay attention to the time of water discharge, matters needing attention in water discharge operation and so on. I hope the following introduction can bring reference to users.Only by working together can we turn yacht generator The value of the play out, the development of the supply market needs. https://usrpower.com/product/usr-pmg-marine-generator-jec80-power-8kva/

　　First, the timing of discharging water from the water tank of marine diesel generator set

　　Stop and wait: drain water 15 minutes after the stop, at which time the water temperature has dropped, avoiding the excessive temperature difference between the fuselage and the external environment caused by immediate water discharge, which will cause deformation of parts, such as cylinder head, and affect the performance of the unit.

　　Avoid draining water at high temperature: Before the engine is turned off, if the temperature is very high, don’t stop immediately to drain water. Unload the load first, make it run at idle speed, and then drain the water when the water temperature drops to 40~50≧. This can prevent the outer surface temperature of the cylinder block, cylinder head and water jacket which are in contact with water from suddenly dropping and shrinking, while the temperature inside the cylinder block is still very high and the shrinkage is small, so it is easy to cause cracks in the cylinder block and cylinder head due to excessive temperature difference between inside and outside.

　　Second, the marine diesel generator water tank water operation

　　Observe the water flow: open the drain valve or switch and pay attention to the specific situation of the water flow. If the water flow is smooth and continuous, it means that the water in the cooling system can be discharged normally. If the water flow becomes smaller or faster or slower, it means that the water contains impurities or scale, which may hinder the normal discharge of water. At this time, the water drain valve or related components should be removed, so that water can be directly discharged from the body. If the water flow is still not smooth, it can be dredged by hard and slender rigid objects such as iron wire until the water flow is smooth.

　　Rocking unit: When the cooling water stops flowing out, the diesel generator set is rocked for a few more turns, so that the residual cooling water that is not easy to flow out will flow out because of the vibration of the marine diesel generator set. This can prevent the water plug on the cylinder head from freezing, thus preventing the cooling water from flowing into the oil shell in the future.

　　Keep the water drain switch in the state: if the water drain switch is not removed, make sure it is in the open state after the water drain is completed, so as to prevent the cooling water that cannot flow out for various reasons from freezing the relevant components of the diesel generator set.

　　Open the water tank cover: open the water tank cover when discharging water, otherwise the cooling water will not flow smoothly, and parts may be frozen due to unclean water discharge in winter.

　　Third, the follow-up treatment

　　Idle drying: In the cold winter, the engine should be started to idle for a few minutes after the cooling water in the engine is released. This is mainly due to the fact that some water may remain in the water pump and other parts after water is drained. After restarting, the residual water in the water pump and other parts can be dried by the body temperature to ensure that there is no water in the engine and prevent water leakage caused by freezing of the water pump and tearing of the water seal.

　　Four, marine diesel generator water tank other maintenance suggestions

　　Maintenance of water tank: the water tank of marine diesel generator set uses pure water, and the radiator is cleaned regularly to prevent internal scaling or deposits from affecting the heat dissipation effect.

　　Preheating measures: when the temperature is low, the marine diesel generator set should be preheated before starting to ensure the smooth start and stable operation of the unit.

　　To sum up, the marine diesel generator set needs to follow certain steps and precautions when draining the water tank in winter, so as to ensure that the water in the cooling system can be completely drained and prevent the related components from being damaged.
