Calleri fires Sao Paulo to win over Corinthians******

SAO PAULO, Oct. 18 (Xinhua) -- An early goal from Argentine striker Jonathan Calleri gave Sao Paulo a 1-0 home victory over Corinthians in Brazil's Serie A championship on Monday.

Calleri struck from close range in the seventh minute after Reinaldo Silva's driving run and cross from the left flank.

Despite controlling most of the possession and looking more dangerous in attack, Corinthians were unable to find an equalizer as Sao Paulo secured their first league victory since September 19.

The Tricolor are now 12th in the 20-team standings with 34 points from 27 matches, six points clear of the relegation zone.

Corinthians are sixth, with 40 points from 27 matches, 16 points behind leaders Atletico Mineiro. Enditem

Cultural China: Modern models of sci******

BEIJING, Nov. 14 (Xinhua) -- If there is a single theme throughout the history of science and technology in China, it is self-improvement.

An ancient Chinese saying from "Zhou Yi," or "The Book of Changes," written over 2,000 years ago, goes: One should never stop striving for self-improvement and hold the world with virtue.

Chinese scientists Gu Songfen and Wang Dazhong, who won China's top science award this year, are modern models of the self-taught man.

Born in 1930, Gu is an aircraft designer at the Aviation Industry Corporation of China, Ltd., the country's leading aircraft maker. At the age of 21, he joined China's aviation industry when it was in its infancy.

In 1956, China's first aircraft design office was established in Shenyang, Liaoning Province, and its first task was to develop the country's first homegrown jet aircraft. Gu was appointed head of the aerodynamics team.

Aerodynamics is the "soul" of aircraft design. The study of the way objects move through the air ensures an aircraft can fly efficiently and carry weapons as well as guaranteeing the stable and safe operation of the engine.

However, in the 1950s, China had no aviation experience, equipment or wind tunnels. Gu decided to teach himself.

After finding foreign texts at the library at Beihang University in Beijing, Gu headed to the capital, borrowed a bike and visited the library every day.

He read a range of books and transcribed all the information he could get his hands on.

Based on that information, Gu came up with an aerodynamic design system and on July 26, 1958, after two years of development, his team celebrated the maiden flight of China's first training jet.

Gu went on to work on the development of the J-8, the country's first supersonic jet fighter, which made its first test flight in 1969 but encountered serious vibration problems during subsequent flights.

To identify the cause of the vibrations, Gu volunteered to observe the aircraft in flight himself.

"We didn't have a camera, so it could only be done by a person," he said. He glued skeins of knitting wool to the J-8's rear fuselage and tail wing to observe their flow during flight.

To get a clear view of the way the wool was disturbed, he required two planes to fly just five meters apart, a great risk for him and his pilot. After several flights, he finally found and fixed the problem.

In 1980, he was in charge of the design of J-8-II, which was required to perform at a much higher level than previous aircraft. In four years, Gu's team achieved the maiden flight of the J-8-II, laying the cornerstone for China's supersonic aircraft design.

Gu's endless curiosity drove his spirit of lifelong learning. He continued his scientific inquiries, translated foreign books, talked with young scholars, and even learned Russian, Japanese and German late in life.

Like Gu, Wang Dazhong's life also reflects a belief in self-improvement. Born in 1935, Wang has dedicated himself to the research and development of advanced nuclear energy technologies.

An internationally reputed nuclear scientist, Wang is former president of China's top-ranking Tsinghua University, which also has self-improvement as its motto.

Over the past six decades, Wang has led his team in blazing a trail, turning China from a latecomer to a leader in advanced nuclear energy technologies.

Wang and his colleagues built from scratch China's first self-developed shielded test reactor at a mountain village in the outskirts of Beijing.

The average age of the design group was under 23, and no one had studied abroad or seen a real nuclear reactor. They started by building engineering models and made designs and calculations with hand-cranked machines.

China's first self-developed nuclear reactor was completed in 1964 after six years of development.

After Three Mile Island in the United States in 1979 and Chernobyl in the Soviet Union in 1986, Wang set his eyes on inherent safety and concentrated research into a high-temperature gas-cooled reactor (HTGR). Although the development of nuclear energy was at a low ebb globally, Wang's resolution to continue in the field was unshaken.

In 1986, Wang and his team again started from scratch to develop a 10MW HTGR and it reached full-power operation in 2003. Its completion ushered in a new generation of nuclear energy systems that effectively eliminate the possibility of reactor core meltdown.

From there, Wang and his team spent years promoting the transition from experimental reactors to industrial-scale prototype reactors. Their achievements helped China independently master modular HTGR technology, and create a comprehensive development chain, from basic scientific research to commercial manufacture.

Likening scientific research to climbing mountains, Wang said the road to success is full of difficulties and risks and requires the ability to analyze problems, the courage to explore uncharted territory, and resilience in the face of failure.

The lives of these two scientists illustrate the ancient saying and echo the call by Chinese leaders to uphold the central role of innovation in China's modernization drive and to be self-reliant in science and technology as a strategic underpinning for national development. Enditem

专访西安交大一附院专家教授施秉银:确诊病例总数应当不容易长期提高******

  12月25日,陕西省增加报表当地确诊病例157例,在其中西安市155例。单天增加超出百例,西安的肺炎疫情还会继续加重吗?华商报小编访谈节目了西安西安交大第一附属医院专家教授施秉银。

  “一些不确定性的感柒沒有被发觉,因此这一两天数据有一定的增加是常规的。”施专家教授表明,确诊病例居高不下这一状况应当迅速可以转好,他可能必须一周以内的時间,增加确诊病例的总数便会降低。

  2020年2月4日,曾任西安交大一附院医生的施秉银领着西安交大一附院的医务人员开赴武汉市。56天時间里,整体队友迎战在接手的武大第一人民医院东院七、八2个危重症病房,共接受126名病人,完成了“零置管、零身亡”的惊喜,顺利完成了救护每日任务。

  说起西安如今遭遇的此次当地肺炎疫情,施专家教授表明,目前为止,他见到确诊的确诊危重症病例总数仅有几起,西安如今遭遇的局势沒有武汉市那时候遭遇的局势那麼焦虑不安,2020年,全国各地都是在开赴武汉市,整体来说,西安现阶段的诊疗救护工作能力彻底可以达到如今的状况。他关心到近期,所有的确诊病例从八院集中化就医至胸科医院,他觉得那样的措施更有益于规范化管理,结合最好是的医疗团队集中化医治。

  这一次确诊病例绝大部分是轻疾,许多人体沒有什么症状,根据抗体检测才发觉感染了新冠病毒,从而可以看得出,此次病毒感染对人会的身心健康的危害要小得多。施专家教授表明,一方面病毒感染在迭代突变,另一方面,群众疫苗接种率极高,身体对木马病毒的免疫能力提升,即使感柒新冠病毒,其表现也变轻。

  施秉银提议一般群众,搞好戴好口罩和拉开距离这两个最重要的事儿。近期一段时间西安逐渐积放的全员Dna,如今大多数抗体检测点也设定在住宅小区,群众做Dna的过程中也一定留意戴好口罩和拉开距离,搞好这两个方面就能防止由于人流量集聚造成互相污染。

  此外,一定降低和外部人或物的触碰,此外有亲人从外边回家,与外部触碰比较多,或是近期十天来过中风险性的地区,家居时还要留意适度的安全防护,可以戴上口罩,一周時间内持续抗体检测呈阴性基本上就能清除感柒很有可能。

Debut win for Xavi, while Sevilla go top, Atletico sneak win in Spain******

MADRID, Nov. 21 (Xinhua) -- Memphis Depay's controversial penalty at the start of the second half was enough to give Xavi Hernandez a 1-0 win over Espanyol in his debut as FC Barcelona coach on Saturday night.。

Memphis scored from the spot after Leandro Cabrera was harshly adjudged to have brought him down, even though TV images showed the defender appeared to have gotten the ball.。

Xavi started with three teenagers in his side, Gavi, Nico Gonzalez and Ilias Akhomach, and in the first half there were signs that he is looking for a more aggressive style of play.。

However, Espanyol did enough to have taken at least a point from the game with Raul de Tomas twice hitting the post in the second half, while Landry Dimata missed a header that looked easier to score after an excellent cross from Wu Lei.。

The Chinese forward also went close in the last move of the game, but just couldn't get enough of his foot onto the ball for what would have been a dramatic equalizer.。

Sevilla temporarily go top of LaLiga but they will be disappointing at dropping two points at home to Alaves, whose recovery continues after a poor start to the season.。

Ivan Rakitic saved a point for Sevilla with a 92nd minute goal after Victor Laguardia's early goal and a 51st minute penalty from Joselu had looked as if they were going to give Alaves an important win.。

Lucas Ocampos scored Sevilla's opener in the 37th minute and Munir almost sneaked a late winner only to be denied by Alaves keeper Fernando Pacheco.。

Felipe's 87th minute header gave Atletico Madrid a 1-0 win at home to Osasuna, who had made life very hard for Diego Simeone's men and hardly suffered in the game before the central defender's decisive header.。

Saturday kicked off with Celta Vigo drawing 1-1 at home to Villarreal, who have now drawn seven games this season.。

Alberto Moreno put Villarreal ahead in the 27th minute, tapping in after a terrible mistake from Celta keeper Mathias Dituro - although Dituro later kept his side in the game with a couple of important saves. Brais Mendez leveled for Celta with 15 minutes left to play after Villarreal keeper Geronimo Rulli failed to hold a shot from outside of the area.。

Levante remain winless all season after their 0-0 draw at home to Athletic Club on Friday night in a rain-soaked Ciudad de Valencia Stadium. Enditem。
