docking to ISS

  The Crew Dragon also had a few jobs of its own to complete. Crew and capsule would spend about two hours performing 3 different burns of the sixteen Draco thrusters outfitted all around the Crew Dragon’s outer shell. The first phasing burn was needed to insert it into the correct orbit, followed a little while later by a boost burn to raise the capsule’s orbit even more. And lastly, a close coelliptic burn to flatten out the orbit around the Earth making it more elliptical, rather than circular matching that of the ISS. These three burns were completed while the crew was awake performing any necessary tasks. Two more burns remained to be completed, but those would need to occur much closure to docking with the ISS, one while the crew slept and one just before autonomous docking procedures were set to begin.

廣州成中高風險區

 廣州今午(30日)召開疫情防控新聞發布會,廣州市衛健委副主任陳斌公布,自5月21日至5月30日,廣州累計新增5宗新型冠狀病毒確診個案,無症狀感染個案21宗。 廣州衛健委表示,廣州第一輪核酸擴大排查現場採樣工作基本結束,累計檢測225.26萬人次,昨日(29日)至今午2時,共發現20人染疫,其中無症狀感染者19人,確診病例1人。 自5月21日爆發疫情以來的感染者中,已檢測的基因測序結果高度同源,均為在印度發現且傳播速度極快的三重變種病毒 delta。 衛生防護中心上周六(22日)曾公布,廣東省被列為中風險地區並暫停廣東省的「回港易」,惟政制及內地事務局在上述消息公布6小時後出稿「轉軚」,將廣東中風險地區收窄至荔灣區龍津街錦龍匯鑫閣,並公布回港易計劃暫時維持不變。   深圳是由最早在英國發現的變異病毒所導致的,其傳染性和傳播能力比以往病毒有所增強。在廣州爲主發生的這起疫情,則是由最早在印度所發現的變異病毒所引起的,這兩個病毒的傳播能力都比以前有所增強,對內地現有的防控措施提出了不小的挑戰 6月1日 深圳市龍崗區出現無症狀本土感染個案,對於是否需要收緊回港易安排,食物及衞生局局長陳肇始表示,正與內地相關單位溝通,目前仍採用國家衞健委的名單。   深圳與廣州近日接連傳出新冠疫情,大陸《財新網》指出,疫情已導致廣州和深圳的港口效率大降,擁堵加劇。全球最大航運公司馬士基5月31日晚間公告,鹽田港防疫措施變嚴,西區作業仍未恢復,東區營運效率僅為正常水平的30%,預計未來一周碼頭將繼續擁堵,船舶延誤時間將延長為7至8天。 深圳5月21日在鹽田港國際貨輪的登輪作業人員例行檢測中,發現1例新冠病毒無症狀感染者,之後透過普篩又發現多名在鹽田港西作業區工作人員也遭新冠病毒感染。為控制疫情,鹽田區5月31日至6月1日對全區戶籍人口和暫住人口,進行第三輪全面核酸檢測。 6月6日 政府晚上更新「回港易」計劃下的風險地區名單,將廣東省廣州、深圳、佛山及茂名市多個區及安徽省六安市一個區,列作中或高風險地區。在抵港當天或之前14天,曾逗留名單上風險地區的香港居民,將不可按「回港易」獲豁免強制檢疫,而須接受14天家居檢疫。 特區政府將廣東省廣州市荔灣、海珠、越秀、番禺和南沙5個區;深圳市的龍崗區的西坑和安良社區,以及鹽田區的沙頭角街道東新村、沙崗圩、東海...

個案11831

   1名29歲乘印尼「GA876」航班來港的外傭(個案編號:11831),她於酒店完成檢疫後,居於僱主位於深水埗南昌站上蓋私人住宅匯璽第5A座家中,在第26日的強制檢測證實染疫。 確診患者的CT值為38,病毒量屬於低,另亦驗出帶有病毒抗體,至於深喉及鼻咽測試結果則暫為不確定。張表示,病人在社區感染的機會較低,由於考慮到她可能在印尼已受感染,故有可能是輸入個案。 問及今日確診外傭有否驗變種病毒,張指,L452R及N501Y的檢測在進行,由於其僱主家入口相通,故第5A及5B座都需強檢。而外傭在西營盤華麗都會酒店檢疫期間的採樣承辦商為Prenetics。 初步個案涉及1名39歲的印尼女傭,患者2月20日乘搭「SQ882」航班,經新加坡抵港,由於她長時間留於香港,若該患者最終確診,將被視為本地感染個案。 該名印傭入境後曾於外傭中心提供的寶寧大廈臨時住所,與另外4名外傭同住;4月6日至5月19日期間則於準僱主伯爵街伯爵園的寓所中居住,家中有6至8名成員,上述2幢大廈將被列入疫廈名單,有關住戶須接受強制檢測。她5月4日曾做檢測,當時未有驗出病毒,5月7日及20日曾往入境處辦理手續,由於她本欲於5月23日返回印尼,故5月21日到梁顯利中心檢測後揭發個案,現列作初步感染。 今日確診外傭於本周四(20日)在白田社區檢測中心進行採樣;而另1名初步確診外傭則在昨日(21日)在梁顯利油麻地社區中心採樣,前者承辦商為香港分子病理檢驗中心有限公司,後者為金域檢驗(香港)有限公司。 袁國勇總結近期7宗本地確診個案的調查分析,當中最近5宗本地個案及可能本地個案(個案11831、11833、11834、11835、11836),5人近月均有外遊紀錄。袁國勇指出,5個案的病毒量均很低,入院時IgG抗體測試為陽性,其中3宗的病毒基因排序顯示與第四波疫情無關,密切接觸者無任何確診個案。港大微生物學系對患者的血清進行測試,發現5名患者的 IgM抗體測試 結果均為陰性,推斷他們早在2至4個月前已感染,相信非在港染疫。衛生防護中心傳染病處主任張竹君表示,明天(30日)會將該5宗個案轉為輸入個案。  

fusion power

 Tokamak:   No current device has been able to generate more fusion power than the heating energy required to start the reaction. Scientists measure this assessment with a value known as fusion gain (expressed as the symbol Q), which is the ratio of fusion power to the input power required to maintain the reaction. Q = 1 represents the breakeven point, but because of heat losses, burning plasmas are not reached until about Q = 5. Current tokamaks have achieved around Q = 0.6 with DT reactions. Fusion power plants will need to achieve Q values well above 10 to be economic. ITER:   timeline ITER > DEMO > PROTO > mass scale fusion energy. by 2060 Feb 2022 In UK, JET’s latest experiment sustained a Q of 0.33 for 5 seconds.

shenzhen SEG plaza wobble 深圳賽格大廈出現搖晃

The tower began to shake at around 1 pm on 18 May       Real-time monitoring of the building’s vibration frequency, tilt rate and settlement degree found that they did not exceed official safety parameters     Merchants were allowed to enter the SEG Electronics Market on Wednesday, but customers were still being denied entry The Shenzhen housing and construction bureau commissioned multiple professional institutions to conduct real-time monitoring of the building’s vibration frequency, tilt rate and settlement degree from 9pm on May 18 to 3pm on May 19, and found them all to be within official ranges set by China’s safety bodies, according to the statement released on the official WeChat account of the Shenzhen government. a preliminary investigation indicated that a combination of three factors, including wind, the subway line below the SEG Plaza, and temperature differences inside and outside the building, likely all played a part in what some expert...

PolyU contributed to Tianwen-1 mission on landing site mapping and evaluation

     Two research teams at The Hong Kong Polytechnic University (PolyU) contributed to the Nation’s first Mars exploration project Tianwen-1. By harnessing their extensive experience in the field of aerospace science and technology, as well as their commitment to research excellence, PolyU researchers played a vital role in the Tianwen-1 mission, in collaboration with the China Academy of Space Technology (CAST). Professor WU Bo helped identify possible landing regions with advanced topographic mapping and geomorphological analysis technologies. Professor YUNG Kai-leung developed a sophisticated space instrument, the “Mars Landing Surveillance Camera (Mars Camera)”, for capturing images of the surroundings of the Red Planet and monitoring the status of the Zhurong Mars rover. Mars landing site mapping and evaluation Landing on Mars is a challenging endeavour due to several reasons, such as the complicated Martian surface, the very thin atmosphere as well as possible dust ...

Ulugh Beg(兀魯伯, 烏魯伯格), great prince of stars

 One of the most important measurements carried out by Ulugh Beg's astronomers was the obliquity of the ecliptic. The ecliptic is the circular path described by the the sun in the course of a year, and its obliquity is the angle at which it cuts the equator. Establishing this precisely is important for a variety of other astronomical measurements and calendar calculations. The astronomers in the classical world had errors on the order of 7'-10'. Arab astronomers achieved for the most part much greater precision; in the case of Ulugh Beg, the error was only -0'32".    The most remarkable instrument in Ulugh Beg’s there was the huge Fakhri sextant, or underground mural quadrant which boasted a radius of 40m, making it, at the time, the largest astronomical instrument in the world of that type. in Samarkand 撒馬爾罕 ( 乌兹别克斯坦 Uzbekistan) The north–south axis of the main building was occupied by a huge sextant with a radius of 40 m (called Fakhrī sextant after that of Khu...

魯平就香港問題答記者問 1993年3月17日 人民日報海外版

 鲁平就香港问题答记者问 如果彭定康一意孤行,中国政府将按基本法的设计“另起炉灶”; 既然英方关闭了谈判的大门,中方不能破门而入;香港问题是中英 两国政府之间的问题,任何第三国无权插手 新华社北京3月17日电 国务院新闻办公室今天举行中外记者招待会,邀请国务院港澳办公室主任鲁平就港英当局突然公布选举安排、破坏中英合作的基础问题阐述中国政府的立场,回答记者的提问。 有记者问,如果港督彭定康坚持“政改方案”,一意孤行,中国政府将采取什么措施。      鲁平回答说,中国政府一贯主张合作,不要对抗。但如果彭定康先生一意孤行,坚持和中国政府对抗的话,中国政府将不得不采取相应措施,按照香港基本法的规定筹组香港特别行政区第一届政府和立法会,也就是大家所说的“另起炉灶”。事实上,这个“炉灶”在香港基本法里已经设计好了。现在说“另起炉灶”,就是按照基本法的设计来砌一个新“炉灶”。这是因为彭定康先生所砌的“炉灶”与基本法不能衔接,到九七年后就不能用了。离九七年只有四年多时间了。从现在开始,我们就要抓紧做好各方面的准备工作。这就是我们要采取的相应措施。鲁平说,在“另起炉灶”的时候,中国政府会坚持贯彻“一国两制”的方针,全面执行基本法的有关规定,争取到九七年香港能实现平稳过渡,顺利交接,保持繁荣稳定。中国政府的这个一贯立场,任何时候都不会动摇。“另起炉灶”的目的,就是为了保持香港的长期繁荣稳定。 有记者问,据英方透露,彭定康突然公布选举安排,是因为中方不愿意定出一个确切的会谈日期。中英两国政府还有没有机会重开谈判,能不能谈一下谈判的过程? 鲁平说,英方的这一说法不确实。中国政府巳经同意在有关谈判的问题已经解决的情况下,在3月份进行谈判,至于在哪一天还有待商定。所以,3月12日彭定康突然在香港立法局发表声明,公布他的所谓“宪制方案”,我们一方面感到非常震惊,另一方面又在意料之中。感到震惊,是因为在3月12日前,双方关于谈判安排的分歧已逐步缩小,几乎已经达成协议,谈判眼看马上可以进行,但遗憾的是他于3月12日下午3时公布了方案。本来,这个问题双方还可以进一步探讨,有些分歧已经逐步缩小,经过双方磋商是不难解决的,所以,我们对彭定康为什么要匆匆忙忙在“宪报”上公布他的所谓方案感到不理解。但另一方面我们觉得又在意料之中,因为我们认为彭定康对中英两国谈判解决有关九四、九五选举问题的分歧本来就...
