1航空微波遥感观测海水表层盐度的研究进展显示文摘盐度是海水的基本特征之一。在开敞海和海岸带进行长期的盐度测量具有重要的意义。利用航空微波技术观测海水盐度的研究始于20世纪60年代末,经过20多年的不断探索,近10年来这一技术研究有了较大的进展。将被动式微波辐射计装在小型飞机上对海水表层盐度进行观测,可以获得同步、快速和大面积的海水表层盐度。目前,已有多种微波辐射计在不同国家和地区的河口海湾和海洋得到使用,如ESTAR、SLFMR、STARRS、PALS和PLMR。使用航空遥感辐射计对海水进行观测,目前,校正后的盐度当分辨率为1 km2时数据准确度和精度都可以达到1psu。利用最新研发的双偏光微波航空遥感技术有望使校正后的盐度数值精度和准确度控制在1psu以内。王永红 M L Heron Peter Ridd 2007海洋地质与第四纪地质2007,27,1:5
2Low temperature,IBA concentrations and optimal time for adventitious rooting of Eucalyptus benthamii mini-cuttings显示文摘Eucalyptus benthamii is a forest species of economic interest that has difficulty with seed production and also is considered to have difficulty with adventitious rooting using propagation techniques,such as cutting or mini-cutting.We aimed to assess the adventitious rooting percentage under different storage times in low temperatures and at various IBA(indole-3-butyric acid) concentrations to determine the optimal time of permanence for rooting Eucalyptus benthamii minicuttings in a greenhouse.Shoots collected from mini-stumps cultivated in a semi-hydroponic system were used to obtain the mini-cuttings.For the first experiment,the mini-cuttings were stored at 4℃ for 0(immediate planting),24,48,72,96 and 120 h.The second experiment evaluated the rooting dynamic to determine the optimal time of permanence for minicuttings in a greenhouse.The basal region of the mini-cutting was treated with various IBA solutions:0(free of IBA),1,000,2,000,3,000 and 4,000 mg·L-1.Every seven days(0(immediate planting),7,14,21 and 28 days),destructive sampling of the mini-cuttings was performed to evaluate the histology of the adventitious rooting.Eucalyptus benthamii minicuttings should be rooted immediately after the collection of the shoots.The 2,000 mg·L-1 IBA concentration induced a greater speed and percentage of adventitious rooting,and an interval of 35 to 42 days was indicated for permanence of the mini-cuttings in the greenhouse.Exposure to low temperature induced adventitious root formation with diffuse vascular connections.Gilvano Ebling Brondani Francisco JoséBenedini Baccarin Heron Wilhelmus de Wit Ondas JoséLuiz Stape Antonio Natal Gonçalves Marcilio de Almeida 2012Journal of Forestry Research2012,23,4:5
3Viral respiratory infections among Hajj pilgrims in 2013显示文摘Middle East respiratory syndrome coronavirus(MERS-Co V) has emerged in the Arabian Gulf region, with its epicentre in Saudi Arabia, the host of the ‘Hajj' which is the world's the largest mass gathering. Transmission of MERS-Co V at such an event could lead to its rapid worldwide dissemination. Therefore, we studied the frequency of viruses causing influenza-like illnesses(ILI) among participants in a randomised controlled trial at the Hajj 2013. We recruited 1038 pilgrims from Saudi Arabia, Australia and Qatar during the first day of Hajj and followed them closely for four days. A nasal swab was collected from each pilgrim who developed ILI. Respiratory viruses were detected using multiplex RT-PCR. ILI occurred in 112/1038(11%) pilgrims. Their mean age was 35 years, 49(44%) were male and 35(31%) had received the influenza vaccine pre-Hajj. Forty two(38%) pilgrims had laboratory-confirmed viral infections; 28(25%) rhinovirus, 5(4%) influenza A, 2(2%) adenovirus, 2(2%) human coronavirus OC43/229 E, 2(2%) parainfluenza virus 3, 1(1%) parainfluenza virus 1, and 2(2%) dual infections. No MERS-Co V was detected in any sample. Rhinovirus was the commonest cause of ILI among Hajj pilgrims in 2013. Infection control and appropriate vaccination are necessary to prevent transmission of respiratory viruses at Hajj and other mass gatherings.Osamah Barasheed Harunor Rashid Mohammad Alfelali Mohamed Tashani Mohammad Azeem Hamid Bokhary Nadeen Kalantan Jamil Samkari Leon Heron Jen Kok Janette Taylor Haitham El Bashir Ziad A.Memish Elizabeth Haworth Edward C.Holmes Dominic E Dwyer Atif Asghar Robert Booy 2014Virologica Sinica2014,29,6:3
