Everest director Baltasar Kormákur was feeling on top of the world at the 1)film premiere at the TCL Chinese Theatre注1 in Hollywood. Kormákur was joyful when he learned that mountaineer Alison Levine注2 called the film 2)trailer the most accurate film 3)portrayal of Earth's highest mountain.It was an achievement the director wanted to make while filming at the Italian 4)Alps and near 5)Everest's South Base Camp in Nepal.  相似文献

There was once a young man who liked 1)puppets so much,he became an 2)apprentice to a master puppet-maker.Sadly,the young man was very 3)clumsy,and his teacher and the other apprentices were always telling him he had no ability to make puppets,he would never succeed.  相似文献

BaFe12O19 fibers was prepared via an aqueous sol-gel process using Fe(OH)(HCOO)2 synthesized in laboratory and Ba(CH3COO)2 as the original materials and citrate as the chelate. The rheological behaviour of spinnable sol was characterized on rheometer, and the development of gel fibers to barium ferrite fibers was studied by IR, TG and XRD. Morphology observation of the fibers was given on SEM, and the diameter of the obtained fibers was between 5 and 10 μm corresponding to different additives. The additives affected the surface tension of the precursor sol which had close relation to the microstructure of fibers. Sucrose and hydroxyethylic cellulose could improve the surface tension while diethanolamine and hexadecylamine reduce that of the precursor sol. And using diethanolamine or hexadecylamine as an additive, well-structured BaFe12O19 fibers could be obtained.  相似文献

One hot day in May,I opened the door of a small Sicilian café and found an elderly woman sitting in the dark.Not realizing the café was closed,I told her in poor Italian about my hope to find a special type of chocolate which is 1)unique to the island. Surprised and happy to see a traveler so early in the season,she asked me to come in and pulled back a curtain.There was a wall of shelves holding nothing but dozens upon 2)dozens of chocolate bars in every 3)flavor 4)imaginable.  相似文献

Background: An ideal aneurysm model of cerebral aneurysm is of great importance for studying the pathogenesis of the lesion and testing new techniques for diagnosis and treatment. Several models have been created in rabbits and are now widely used in experimental studies; however, every model has certain intrinsic limitations. Here we report the development of a novel saccular aneurysm model in rabbits using an arterial pouch that is subject to in vitro pre-digestion with combined elastase and collagenase. Methods: A segment of right common carotid artery (CCA) was dissected out and treated with elastase (60 U/ml, 20 min) followed by type I collagenase (1 mg/ml, 15 min) in vitro. The graft was anastomosed to an arterial arch built with the left CCA and the remaining right CCA, while the other end of the graft was ligated. The dimension and tissue structure of the pouch were analysed immediately, 2 or 8 weeks after operation. Findings: Ten terminal aneurysms were produced. The gross mor-phology of the aneurysm resembles the human cerebral terminal aneurysms. We have observed the following pathological changes: (1) growth of the aneurysm (mean diameter increased from (2.0±0.1) to (3.2±0.3) mm at 2 weeks, P<0.001, n=7~10); (2) thinning of the aneurysmal wall (the mean wall thickness decreased to 44% at 2 weeks), which was accompanied by significant losses of elastic fibres, collagen and the cellular component; and (3) spontaneous rupture (3 out of 9, one aneurysm ruptured 24 h after operation with the other two at 2 and 4 weeks respectively). Conclusion: This rabbit arterial pouch model mimics human cerebral aneurysms in relation to morphology and histology. In particular, this model exhibited an increased tendency of spontaneous rupture.  相似文献

Interaction Between DEHP and Particulate in a Eutrophic Lake   总被引:2,自引:0,他引:2  
Characteristics of interaction between di-2-ethylhexyl phthalate(DEHP) and particulate in a eutrophic lake were studied in this paper. DEHP concentrations ranged from 89.9 to 247 μg/L with an average value of 146 μg/L in subsurface water (SSW) samples, and from 82.0 to 390 μg/L with an average value of 211 μg/L in water surface microlayer (SM) samples. The results indicate that there was only a weak correlation between the DEHP concentrations and suspended particulate material(SPM) concentrations in both SSW and SM,while the significant correlation between DEHP concentrations and chlorophyll a concentrations was found,which suggestes that DEHP was principally bound to phytoplankton in the eutrophic lake. Correlation between DEHP concentrations and total phosphor (TP) concentrations was also found in this investigation. Enrichment factors (EF) of DEHP in SM were in the range of 0.85 to 2.12 with an average value of 1.35..DEHP EFs were significantly related to the enrichment of chlorophyll a in SM. The results suggest that the enrichment of DEHP in SM of this eutrophic lake was mainly due to DEHP accumulation in phytoplankton and was controlled by distribution of phytoplankton between SM and SSW.  相似文献

Chris Bosh and Kobe Bryant won an Olympic gold medal in the 2008 Summer Games in Beijing as a part of the "1)redeern team"under Coach K,and in a 2)touching blog post on his own website,Bosh 3)paid tribute to Bryant following his retirement and remembered how Kobe's4)work ethic left him amazed on the first day of practice. "On the first practice day with that team,I went down to get breakfast before we took the bus over to the gym.There I was,thinking I was pretty early and feeling good about myself and Kobe's already there.He got up,said hello and walked out to get ready for practice.  相似文献

In this paper, a semi on-line version on m identical machines M1 , M2, …, Mm ( m ≥ 3 ) was considered, where the processing time of the largest job is known in advance. Our goal is to maximize the minimum machine load, an NPLS algorithm was presented and its worst-case ratio was proved to be equal to m - 1 which is the best possible value. It is concluded that if the total processing time of jobs is also known to be greater than (2 m - 1 )Pmax where pmax is the largest job‘s processing time, then the worstcase ratio is 2 - 1/m.  相似文献
