西安为什么要进行积放核酸筛查工作中?官方解答来了!******

  华商网讯 12月25日,西安举办新冠肺炎疫情防控工作中记者招待会(第36场),邀约相关负责同志详细介绍有关状况。

由于现阶段“德尔塔”病毒变异株具备传播力强、快速传播快、病毒载量高特性,仅有根据规模性群体Dna筛查,才可以快速发觉潜在性病案,查清并锁住风险性地区和关键群体,立即采用目的性管控措施,阻隔肺炎疫情蔓延。

  那麼为何要进行积放Dna筛查呢?关键根据下列二点缘故:一是由于新冠病毒具备一定的替伏期,一小部分感染者存有空隙性排毒状况,而采样仅仅一个时间点,假如采样时不排毒或是那时候病毒感染浓度值不足,小于检出限,就很有可能检验不上,尤其是没有症状的感染者,初期排毒水准并不高,身体内病毒感染浓度值很低。二是采样时咽拭子收集的深层、部位和咽拭子与粘膜沾染的时长等原因也会影响到結果的精确性。假如采样的技巧不标准,无法收集到适宜的部位,很有可能出现误检。

  再再加上本市巨大人口数量,假如仅进行极少数几场核酸检测通常难以筛查出所有感染者。因而,进行积放规模化核酸检测针对尽快发觉新冠病案及没有症状的感染者、执行精确防治,是十分必要的。

  在这里,提示广大群众,依据小区分配,立即参与核酸检测,是保护自己、维护亲人,也是对社会发展承担责任。

  此外,今日西安下雪了,气温降低、雪天路滑,请诸位群众参与核酸检测时留意防冻保暖、安全出行,不聚堆、不集聚、不闲聊,戴好口罩、井然有序排长队、维持“一米线”,感谢大家了解和相互配合!核酸检测結果未出去以前,请家居耐心等待。

Huge luge breakthrough as talent system reaps rewards******

Former endurance skier Fan Duoyao stole the show at the Luge World Cup's Chinese debut in Yanqing over the weekend as the host continues to reap the benefits of its cross-sport talent system.。

China only began assembling a luge team in 2015, while the Olympic track at Yanqing opened just over a year ago. Yet, the nation has made rapid progress in developing luge from scratch, with Fan's history-making Cup appearance on Saturday boosting the country's preparations for next year's home Winter Olympics.。

Fan converted to the sport from cross-country skiing six years ago as part of an ambitious program to develop Chinese lugers, established after Beijing won the Olympic bid.。

He completed two runs in Saturday's men's singles final at the International Luge Federation's World Cup season opener at the National Sliding Center-the first time a Chinese athlete had competed in the sport's elite series.。

Despite finishing last among the 32 finalists with a combined time of 1 minute 59.308 seconds, Fan took pride in the huge strides China has made in the Western-dominated sport.。

"I think me being here and completing two runs today proved that our program is working as expected," said Fan, who qualified for the final after knocking out the 33rd-place finisher by a mere one-thousandth of a second in Friday's preliminary round.。

"Don't get me wrong, the gap remains quite big but it is closing. We should be encouraged that we are going in the right direction."

German luger Johannes Ludwig, a member of the country's reigning Olympic champion relay squad, won the gold in a track-record time of 1:54.597.。

Ludwig's teammate and six-time overall World Cup winner Felix Loch took silver, 0.854 seconds back. Their younger compatriot Max Langenhan, a former world junior champion, claimed bronze to underline Germany's undisputed supremacy in the sport.。

As the fastest of all three sliding sports, luge is most definitely not for the faint-hearted, with athletes hurtling down a narrow frozen track lying feet-first on a thin sled at speeds of up to 150 kph.。

The Yanqing leg of the World Cup, which doubled as an Olympic test event and qualifying meet, saw 300 local fans watch the hair-raising action track-side. It was the first time Beijing 2022 organizers welcomed spectators on site since the test events for the Winter Games began in February.。

Local resident Peng Sisi said watching world-class lugers push their limits for speed was a breathtaking experience that further whetted her appetite for the Olympics, which will open on Feb 4.。

"It was really exciting to cheer for our own athlete on a new track just built on our doorsteps. We just can't wait to welcome athletes from around the world and be a warm host to them all," she said.。

Fan's World Cup debut builds on a series of breakthroughs by Chinese athletes in sliding sports, including former long jumper Geng Wenqiang's qualification for the 2018 Winter Olympics in South Korea and the Chinese four-man bobsled team's seventh-place finish at a World Cup meet in Switzerland in February 2020.。

The cross-sport development system, launched by China's central sports governing body in 2015, drafts athletes primarily from track and field, gymnastics and martial arts, and applies their skill sets to winter sports.。

Fan was one of eight athletes selected to the national luge team from a group of hopefuls drafted to the cross-sport program in 2015.A long hiatus from international events amid the pandemic has somewhat hamstrung their development, but Saturday's breakthrough bodes well for the future.。

"I've never been intimidated by foreign opponents because we know that with the home track ready for the Olympics we have enough runs and tests to narrow the gap to them," said Fan, a 24-year-old native of Inner Mongolia.。

Although still far from reaching the podium, Chinese athletes have undoubtedly made their presence felt on the world stage.。

"It's definitely important for our sport to go global and be promoted in new markets such as China," German luger Langenhan said through an interpreter.。

"We are happy to see a Chinese athlete join us on the World Cup stage and hopefully we will see more of them in the future."

秦创原:打造陕西创新驱动发展总平台******

  全省高新技术企业数量同比增长32.30%、科技型中小企业总数同比增长38.67%、技术合同成交额同比增长33.23%……陕西创新发展亮点纷呈,秦创原创新驱动平台建设成效明显。

  自2021年3月秦创原创新驱动平台建设启动以来,陕西举全省之力围绕加快把创新优势转化为发展优势,开展了一系列探索试验。

  深化改革   为创新者撑腰

  2021年,西北工业大学航空学院教师李占科迈出了从“科学家”到“企业家”的一大步。2021年9月,李占科团队的消防特种无人机项目正式转化并落地西咸新区秦创原总窗口。

  陕西创新优势明显,但是科技存量资源与科技成果转化能力薄弱及转化体制机制不畅的问题仍然存在。在秦创原创新驱动平台建设中,陕西首先从“人才”和“机制”两方面破题。

  以西北工业大学等高校为试点,陕西开展了赋予科研人员职务科技成果所有权或长期使用权试点改革,着力破除制约科技成果转化的机制障碍。

  “成果转化中,公司注册资本为1000万元,我们团队以专利作价600万元入股,负责公司的运营和发展。同时,学校在持股比例、职称评定等方面对我们开展科技成果转化进行了政策倾斜。”李占科介绍。2021年,西北工业大学组建科技成果转化企业数量同比增长75%。

  2021年6月7日,陕西首批揭榜挂帅课题榜单发布,面向全国公开征集解决方案和承担单位。“发榜者”即技术需求方为陕西7家创新型领军企业。

  这标志着陕西深化科研项目管理改革迈出新的步伐。“推进创新攻关揭榜挂帅体制机制改革”被明确写入《秦创原创新驱动平台建设三年行动计划(2021—2023年)》中。陕西试行科研项目领衔专家制、“揭榜挂帅”、“赛马制”,以企业需求为导向,构建企业行业技术创新平台,赋予科研机构和科研人员更大的技术路线决策权。截至目前,陕西已发布四批揭榜挂帅项目榜单,涉及20多家行业领军企业,多所高校、科研单位参与其中。

  改革探索需要强有力的政策措施“保驾护航”。

  秦创原创新驱动平台建设启动伊始,陕西发布“政策包”,涵盖了科技人才、成果转化、企业创新、科研平台、服务体系等5大类共70条措施。随着秦创原创新驱动平台建设的加快,全省各市、创新主体、平台园区制定了相应的协同推进政策,形成了多层次、多维度、全社会协同的“1+N”政策体系。

  “两链”融合   科技和产业共舞

  在秦创原创新驱动平台的政策和资源加持下,西安赛隆实现了快速发展:企业自主研发的国内首台电子束3D打印设备和国内唯一的3D打印金属粉末制备装置,国内市场占有率均达到90%以上;高品质金属粉末粉床电子束3D打印技术与装备产业化项目开工建设,项目建成后将带动陕西3D打印设备与产品开发再上新台阶。

  西安赛隆是陕西增材制造产业链的龙头企业之一。2021年,陕西明确了包括增材制造产业链在内的23条重点产业链。针对科技资源富集而产业发展不强的现实,陕西把推动“两链”深度融合作为秦创原创新驱动平台建设的重中之重。

  随着秦创原创新驱动平台建设的启动,“两链”融合科技行动在全省展开。2021年,陕西承接国家重点研发计划40余项,并首次与科技部联合组织实施2个国家重点研发计划部省联动专项。省科技厅梳理凝练了29个重点领域2662项关键核心技术需求,部署实施8个科技重大专项和272个重点产业链创新项目。

  围绕促进“两链”深度融合的新型研发平台的探索也在进行。

  2021年3月30日,在秦创原创新驱动平台建设大会上,陕西启动了先进稀有金属材料、光子产业、半导体与集成电路、高档数控机床等首批4个共性技术研发平台建设工作,赋予他们在共性技术研发、行业开放共享、企业孵化培育、人才引进培养、体制机制创新等方面开展探索试验。

  其中,先进稀有金属材料共性技术研发平台的牵头单位西北有色金属研究院被省委、省政府定位为“新型科研机构”,成为秦创原创新驱动平台建设的示范点。截至目前,该院已成功孵化39个公司,其中有3个上市公司和4个新三板挂牌公司,实现了高质量的“两链”融合发展。

  协同联动   释放创新潜能

  2021年初,西安交通大学李洋教授带着一项名为“非粮生物质一体化制氢及储氢”的项目先后对接了多家单位,希望得到支持,开展中试生产,均未能如愿。秦创原创新驱动平台建设启动后,该项目得到春种基金青睐;在秦创原路演平台展示时,该项目又获得另外一家机构跟投,最终得到了两家机构的联投。

  秦创原创新驱动平台建设启动以来,科技成果在陕西快速就地转化,科技型企业培育孵化提质增效。科技成果的快速转化,离不开创新资源的协同联动。

  路演平台就是让创新资源充分对接的一个尝试。按照“秦创驿站”“每周发布”和“月度专场”三种形式,陕西打造了“三级跳台”式的常态化路演平台。截至目前,全省举办各类路演活动130多场,推介科技成果转化项目3000余项,辅导路演680余项,300余家投资机构参与,130多个项目和团队完成融资,规模超13亿元。

  高校、科研院所、企业的协同联动不断深入,一批产业创新平台加快建设。截至目前,陕西建设190个省级工程技术研究中心、40余个产业技术创新战略联盟、84个“四主体一联合”新型研发平台。

  秦创原总窗口的服务能力不断向各地辐射:宝鸡市以“一把手带头进高校,院士宝鸡行、企业老总院校行、专家企业行”活动创新校地合作模式;商洛市探索“飞地创新、离岸孵化、回迁发展”模式,在秦创原总窗口布局建设约4万平方米的空间载体;铜川市设立2亿元的高新科技成果创业投资基金,在中国西部科技创新港挂牌成立的铜川创新谷投入运行……(记者:张梅)

China to cultivate more researchers for cultural relics studies******

BEIJING, Nov. 6 (Xinhua) -- The number of researchers specializing in cultural relics is expected to increase by 25 percent by 2025, according to a five-year plan for cultural relics protection and sci-tech innovation in relevant fields, which will soon be released.。

Li Qun, vice minister of culture and tourism and head of the National Cultural Heritage Administration, elaborated on the document at a press conference held in Beijing earlier this week.。

China boasts 767,000 immovable cultural heritage sites and 108 million pieces (sets) of state-owned movable cultural relics. Despite its rich cultural heritage resources, statistics show that the country only has 175,700 personnel in the industry.。

To solve this issue, the document highlights the cultivation of more archaeological talent. Measures include expanding enrollment of relevant majors in colleges and universities and setting up related majors at vocational education institutions, Li said.。

The document also proposes to innovate talent employment and management in the field. Enditem。
