It was a bad vintage, no one will dispute it: the winds were not there on the European continent last year. Thus, among the leaders in the field, Germany, Great Britain and Denmark, in the last quarter – in principle windy -, windmills only turned around 14% of their installed capacity, compared to 20% to 26% in previous years. In Switzerland, wind power production has declined slightly, explains Lionel Perret, director of the Suisse Eole organization: “Our country is interesting because, with seven different wind regimes, it is located at a crossroads. If there is no wind in the Jura, there may be some elsewhere. “

The cost of the mandatory PCR test for all arrivals will be reduced to thirty dollars instead of fifty
written by Alexandra Hartman Editor-in-Chief
The media office of the Ministry of Public Health announced in a statement that, “starting next Monday, the tenth of January, the cost of the mandatory PCR test for all arrivals will be reduced upon arrival at Rafic Hariri International Airport, with the exception of children under 12 years old, to become thirty dollars. instead of fifty.
The statement pointed out that “the expatriates must register on the electronic platform of the Ministry of Public Health for expatriates https://PASS.MOPH.GOV.LB, and pay the cost of the PCR test on the mentioned platform according to a new mechanism that adopts one of two options: a credit card or an electronic document. EMD is obtained by passengers by paying at one of the approved travel and tourism offices or in the sales offices of the airline, provided that the passengers deliver the EMD receipt to representatives of the Ministry of Public Health upon their arrival at the airport.
The Ministry was keen to confirm that “its platform guarantees the requirements of protection and security for data confidentiality in accordance with international standards according to which continuous penetration tests and checks are conducted, and that personal data is encrypted and stored in a secure manner and cannot be viewed by the public, and is used only in the event that the person concerned is infected. With the virus, or contact with a positive case, to contact it and give it the necessary directions with the aim of limiting the spread of the epidemic.

A fan of “Abdulaziz Attia”: Who is the leader of Asia .. And your opinion of Nishimura’s ruling? .. Witness: An unexpected response from the latter!

Al-Marsad Sports: A fan asked an interesting question to the Kuwaiti journalist, Abdulaziz Attia, regarding the Asian leader.
The fan said during the “Derby” program broadcast on the Kuwaiti channel “atv”: “Who is the leader of Asia… and your opinion of Nishimura’s ruling?!”
Laird, “Atia,” said: “The Asian leader is Al-Nasr, the first international in Asia to participate in the Club World Cup, and a team that takes its championships with its arm and not with the help of a friend, and the referee is Nishimura men.”
Scientists watch the moment of the explosion of a red giant star for the first time
written by Alexandra Hartman Editor-in-Chief
succeeded Astronomy scientists On Thursday, January 6, at American universities, they monitored the process of fading a giant star in a process that is the first of its kind that may greatly serve astronomical research in the future.
Supervised by Northwestern University and the University of California, a team of scientists watched a dramatic and violent display of the death of a star called “thross”, a type of massive star that self-destructs and dies and collapses into a permanently raging mass.
It should be noted that a star explodes every second somewhere in the universe, but the death of the star “Thross”, known as a red giant and which astronomers have always watched, is the first death of its kind, according to astronomers.
There is another type of star that always turns into raging masses, and the difference between it and “Thros” is the process of its collapse, where the star collapses by itself following a collision with another body, to explode and become impossible to erupt following that, and this process is called the classical explosion.
Astronomers also observed for the first time the rapid self-destruction of the massive star, while its body collapsed, turning into a permanently burning mass to be nicknamed the “supernova”.
It is mentioned that before this historical event, it was believed that these giant stars did not provide any evidence of their impending explosions, but this star was monitored as it was emitting bright radiation that indicated that it had entered its last days. Scientists at the University of Hawaii Institute of Astronomy had detected these radiation in the summer of 2020.
According to the scientists, this process indicates that at least some of these stars undergo significant changes in their internal structure in their last days, which then lead to turbulent expulsion of gas moments before collapsing.
The lead astronomer for the study, Wayne Jacobson Gallan, said: “This discovery contributes to our understanding of what massive stars do moments before they die. No such activity has been observed before such a giant star before it transforms into a supernova. For the first time, we’ve seen a red giant star explode. “.
It is noteworthy that stars classified as “red giants” usually have a mass 10 times greater than the mass of the sun of a planet the earthIt is extremely cold, with surface temperatures reaching minus 6,920 degrees Fahrenheit. In addition to its cold surface, it usually has enormous diameters. The radius of most red giants is between 200 and 800 times the radius of the Sun.
Boom!Astronomers have imaged in real time the dying breath of a red supergiant. Via 2 Hawai’i telescopes @keckobservatory & @UHIfA Pan-STARRS, they watched the star self-destruct during its last 130 days before going supernova.
