| 1 | COREX工艺燃料比的影响因素显示文摘作为一种新型非高炉炼铁工艺,COREX工艺使用80%~85%非焦煤和15%~20%焦炭作为燃料,以满足对热量和还原剂的需求,并保证熔融气化炉内半焦床具有足够透气性。用于COREX工艺的非焦煤应满足一定的物化和高温性能,以稳定操作和提高产量。印度金达尔(JSW)钢铁厂拥有两座各年产80万t的COREX熔融还原炉,使用过几个煤种,发现不同煤种对操作会产生重要影响。统计分析表明,影响燃料比的主要因素包括煤的水分和挥发分、渣比和熔化速率。研究发现,生产率较高时,半焦床的稳定性和透气性就显得非常关键,因此反应后的半焦应具有较高的强度。 | P.

| 2 | 白蛋白刺激肾小管上皮细胞表达基质金属蛋白酶2和9显示文摘目的探讨白蛋白对近端肾小管上皮细胞表达基质金属蛋白酶2(MMP-2)和MMP-9的影响。方法大鼠近端肾小管细胞株NRK52E培养至70%或100%融合时,分别给予不同浓度(0.1~1.0g/L)去脂和非去脂牛血清白蛋白(dBSA和BSA)刺激,于24、48、72h收集培养液,用明胶酶谱和Western印迹方法检测培养液MMP-2和MMP-9活性和蛋白水平。结果与空白对照组比较,1.0g/LBSA刺激未完全融合NRK52E72h后,MMP-2和MMP-9活性分别上调276%、176%(P〈0.05)。与刺激24h比较,1.0g/LBSA刺激72h,在未完全融合NRK52E的MMP-2和MMP-9活性分别上调536%、148%;在完全融合NRK52E分别上调212%、184%(P〈0.05)。与完全融合NRK52E比较,1.0g/LBSA刺激未完全融合NRK52E 72h,MMP-2活性上调增加了274%,MMP-9活性上调减少了45.1%(P〈0.05)。dBSA刺激结果与BSA类似。结论白蛋白刺激呈剂量和时间依赖性上调近端肾小管细胞表达MMP-2和MMP-9。细胞完全融合可抑制MMP-2表达,促进MMP-9表达。 | 孙良忠 Ibrini Juma Parker Emma 陈述枚 Johnson Timothy S.

| 4 | Large scale hybrid Monte Carlo simulations for structure and property prediction显示文摘The Monte Carlo method is one of the first and most widely used algorithms in modern computational physics.In condensed matter physics,the particularly popular flavor of this technique is the Metropolis Monte Carlo scheme.While being incredibly robust and easy to implement,the Metropolis sampling is not well-suited for situations where energy and force evaluations are computationally demanding.In search for a more efficient technique,we here explore the performance of Hybrid Monte Carlo sampling,an algorithm widely used in quantum electrodynamics,as a structure prediction scheme for systems with long-range interactions.Our results show that the Hybrid Monte Carlo algorithm stands out as an excellent computational scheme that can not only significantly outperform the Metropolis sampling but also complement molecular dynamics in materials science applications,while allowing ultra-large-scale simulations of systems containing millions of particles. | Sergei Prokhorenko Kruz Kalke Yousra Nahas Laurent Bellaiche | 2018 | npj Computational Materials2018，，1： | 3 |
| 5 | Mineralogy,M-type tetrad effect and radioactivity of altered granites at the G.Abu Garadi shear zone,central Eastern Desert,Egypt显示文摘The G. Abu Garadi area is covered mainly by metasediments, alkali feldspar granites and stream sediments. The alkali feldspar granite is traversed by a major strike-slip fault trending in an N-S direction as well as two subordinate sets of faults trending NW to WNW for the first one and NE for the second one. These faults represent the shear zones affected by magmatic (syngenetic) as well as hydrothermal (epigenetic) activities causing alteration of the granitic rocks. The most common alteration features are albitization, greisenization and koalinitization. The mass balance calculations of the studied altered samples show enrichments in Zr, Y, Ni, U, Th and Ga and depletions in Zn, Sr, Nb, Ba, Pb, Cu and V. Only the greisenized samples exhibit a significant enrichment in Nb, ∑REE budget and pronounced lanthanide tetrad effect (M-type), especially TE1,4, while weakly expressed tetrad effects are for the other albitized and koalinitized samples. Mineralogically, the common accessory minerals in the altered samples include samarskite-(Y), betafite, uranothorite, zircon, fluorite and cassiterite. The greisenized granites contain high eU and eTh than the other altered types, where they are characterized by an assemblage of the radioactive minerals; samarskite-(Y), betafite, uranothorite in addition to zircon. The inter-element relationships between U and Th and also their ratios illustrate that the radioelement distribution in these granites is mainly governed by magmatic processes, in addition to post-magmatic ones. The distribution of chemical elements and the fractionation of some isovalents within the shear zone are largely controlled by the newly formed mineral phases. With respect to uranium mobilization, uranium migrated from the host alkali feldspar granites of G. Abu Garadi, while the shear zones acted as traps for the migrated uranium. Moreover, U migrated in the shear zone during greisenization and albitization, and migrated out during koalinitization. | El Nahas H.A. El Feky M.G.

| 6 | Brucellosis and tuberculosis:Clinical overlap and pitfalls显示文摘Objective:To identify characteristic features of tuberculosis in patients with culture proven brucellosis.Methods:A retrospective analysis was performed on patients diagnosed with culture proven brucellosis between January and December 2011,based on review of their medical records.Patients with demonstrable co-infection with tuberculosis were excluded.Clinical features,laboratory parameters and tissue histopathology reports where available were noted.Results:Thirty-two patients with brucellosis were included in the study.Twenty-one(65.63%)patients had chronic fever,thirteen(40.63%)had a productive cough,while significant weight loss,evening rise of temperature and night sweats were reported by eight(25.00%),eleven(34.38%)and five(15.63%)patients respectively.Nine(28.13%)patients had at least three of these symptoms.Lymphadenopathy,hepatomegaly and splenomegaly were noted on examination in seven(21.88%),fifteen(46.88%)and twelve(37.50%)patients respectively.Eight(25.00%)patients had hepatosplenomegaly,of these only two had associated significant lymphadenopathy.Respiratory examination was normal in all patients.Elevated ESR greater than 50 mm/hr was seen in eight(25.00%),it was greater than 100 mm/hr in five(15.63%)patients.Hypergammaglobulinemia was seen in eight(25.00%)cases.Bone marrow biopsy showed non-caseating granulomas in three(9.38%)cases,lymph node biopsy showed granulomas in one case.Overall,three(9.38%)patients had known risk factors for tuberculosis,while six(18.75%)had risk factors for brucellosis.Conclusions:There is a clear overlap between brucellosis and tuberculosis both in terms of clinical presentation and laboratory parameters.It is essential to c-arefully rule out tuberculosis in all cases of suspected or proven brucellosis before initiating antimicrobial therapy,in order to forestall development of drug-resistant tuberculosis. | Sowjanya Dasari Kushal Naha Mukhyaprana Prabhu | 2013 | Asian Pacific Journal of Tropical Medicine2013，6，10： | 2 |

| 8 | Short-term outcomes after laparoscopic colorectal surgery in patients with previous abdominal surgery: A systematic review显示文摘AIM: To perform a systematic review focusing on shortterm outcomes after colorectal surgery in patients with previous abdominal open surgery(PAOS).METHODS: A broad literature search was performed with the terms 'colorectal', 'colectomy', 'PAOS', 'previous surgery' and 'PAOS'. Studies were included if their topic was laparoscopic colorectal surgery in patients with PAOS, whether descriptive or comparative. Endpoints of interest were conversion rates, inadvertent enterotomy and morbidity. Analysis of articles was made according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses.RESULTS: From a total of 394 citations, 13 full-texts achieved selection criteria to be included in the study. Twelve of them compared patients with and without PAOS. All studies were retrospective and comparative and two were case-matched. The selected studies comprised a total of 5005 patients, 1865 with PAOS. Among the later, only 294(16%) had history of a midline incision for previous gastrointestinal surgery. Conversion rates were significantly higher in 3 of 12 studies and inadvertent enterotomy during laparoscopywas more prevalent in 3 of 5 studies that disclosed this event. Morbidity was similar in the majority of studies. A quantitative analysis(meta-analysis) could not be performed due to heterogeneity of the studies. CONCLUSION: Conversion rates were slightly higher in PAOS groups, although not statistical significant in most studies. History of PAOS did not implicate in higher morbidity rates. | Marleny Novaes Figueiredo Fabio Guilherme Campos Luiz Augusto D'Albuquerque Sergio Carlos Nahas Ivan Cecconello Yves Panis | 2016 | World Journal of Gastrointestinal Surgery2016，8，7： | 2 |
