| 3 | Combined Fenton process and sulfide precipitation for removal of heavy metals from industrial wastewater:Bench and pilot scale studies focusing on in-depth thallium removal显示文摘Thallium (Tl) in industrial wastewater is a public health concern due to its extremely high toxicity. However, there has been limited research regarding Tl removal techniques and engineering practices to date. In this investigation, bench and pilot studies on advanced treatment of industrial wastewater to remove Tl to a trace level were conducted. The treatment process involved a combination of hydroxide precipitation, Fenton oxidation, and sulfide precipitation. While hydroxide precipitation was ineffective for Tl^+ removal, it enabled the recovery of approximately 70%-80% of Zn as Zn hydroxide in alkaline conditions. The Fenton process provided good Tl removal (>95%) through oxidation and precipitation. Tl was then removed to trace levels (< 1.0 μg/L) via sulfide precipitation. Effective removal of other heavy metals was also achieved, with Cd < 13.4 μg/L, Cu < 39.6 μg/L, Pb < 5.32 μg/L, and Zn < 357 μg/L detected in the effluent. X-ray photoelectron spectroscopy indicated that T12S precipitate formed due to sulfide precipitation. Other heavy metals were removed via the formation of metal hydroxides during hydroxide precipitation and Fenton treatment, as well as via the formation of metal sulfides during sulfide precipitation. This combined process provides a scalable approach for the in-depth removal of Tl and other heavy metals from industrial wastewater. | Huosheng Li Hongguo Zhang Jianyou Long Ping Zhang Yongheng Chen | 2019 | Frontiers of Environmental Science & Engineering2019，13，4： | 6 |
| 4 | Clinical value of Helicobacter pylori stool antigen test,Immuno Card STAT HpSA,for detecting Hpylori infection显示文摘AIM:To evaluate the reliability of the Helicobacter pylori stool antigen test, ImmunoCard STAT HpSA, for detecting Hpylori infection.METHODS:Stool specimens were collected from 53 patients who received upper endoscopy examination due to gastrointestinal symptoms.ImmunoCard STAT HpSA was used to detect Hpylori stool antigens. Hpylori infection was detected based on three different tests:the urease test,Warthin-Starry staining and culture. Hpylori status was defined as positive when both the urease test and histology or culture alone was positive.RESULTS:Sensitivity,specificity,positive predictive and negative predictive values and the total accuracy of ImmunoCard STAT HpSA for the diagnosis of Hpyloriinfection were 92.6% (25/27), 88.5% (23126), 89.3% (25/28), 92%(23/25) and 90.6% (48/53), respectively.CONCLUSION:The stool antigen test, ImmunoCard STAT HpSA,is a simple noninvasive and accurate test for the diagnosis of Hpylori infection. | Yi-HuiLi HongGuo Peng-BinZhang Xiao-YanZhao Si-PingDa | 2004 | World Journal of Gastroenterology2004，10，6： | 6 |
| 5 | Whole-genome resequencing of Osmanthus fragrans provides insights into flower color evolution显示文摘Osmanthus fragrans is a well-known ornamental plant that has been domesticated in China for 2500 years.More than 160 cultivars have been found during this long period of domestication,and they have subsequently been divided into four cultivar groups,including the Yingui,Jingui,Dangui,and Sijigui groups.These groups provide a set of materials to study genetic evolution and variability.Here,we constructed a reference genome of O.fragrans‘Liuyejingui’in the Jingui group and investigated its floral color traits and domestication history by resequencing a total of 122 samples,including 119 O.fragrans accessions and three other Osmanthus species,at an average sequencing depth of 15×.The population structure analysis showed that these 119 accessions formed an apparent regional cluster.The results of linkage disequilibrium(LD)decay analysis suggested that varieties with orange/red flower color in the Dangui group had undergone more artificial directional selection;these varieties had the highest LD values among the four groups,followed by the Sijigui,Jingui,and Yingui groups.Through a genome-wide association study,we further identified significant quantitative trait loci and genomic regions containing several genes,such as ethylene-responsive transcription factor 2 and Arabidopsis pseudoresponse regulator 2,that are positively associated with petal color.Moreover,we found a frameshift mutation with a 34-bp deletion in the first coding region of the carotenoid cleavage dioxygenase 4 gene.This frameshift mutation existed in at least one site on both alleles in all varieties of the Dangui group.The results from this study shed light on the genetic basis of domestication in woody plants,such as O.fragrans. | Hongguo Chen Xiangling Zeng Jie Yang Xuan Cai Yumin Shi Riru Zheng Zhenqi Wang Junyi Liu Xinxin Yi Siwei Xiao Qiang Fu Jingjing Zou Caiyun Wang | 2021 | Horticulture Research2021，8，1： | 5 |
| 6 | Detecting land subsidence near metro lines in the Baoshan district of Shanghai with multi-temporal interferometric synthetic aperture radar显示文摘Land subsidence is a major factor that affects metro line(ML) stability. In this study, an improved multitemporal interferometric synthetic aperture radar(InSAR)(MTI) method to detect land subsidence near MLs is presented. In particular, our multi-temporal InSAR method provides surface subsidence measurements with high observation density. The MTI method tracks both point-like targets and distributed targets with temporal radar backscattering steadiness. First, subsidence rates at the point targets with low-amplitude dispersion index(ADI) values are extracted by applying a least-squared estimator on an optimized freely connected network. Second, to reduce error propagation, the pixels with high-ADI values are classified into several groups according to ADI intervals and processed using a Pearson correlation coefficient and hierarchical analysis strategy to obtain the distributed targets. Then,nonlinear subsidence components at all point-like and distributed targets are estimated using phase unwrapping and spatiotemporal filtering on the phase residuals. The proposed MTI method was applied to detect land subsidence near MLs of No. 1 and 3 in the Baoshan district of Shanghai using 18 TerraSAR-X images acquired between April 21,2008 and October 30, 2010. The results show that the mean subsidence rates of the stations distributed along the two MLs are-12.9 and-14.0 mm/year. Furthermore, three subsidence funnels near the MLs are discovered through the hierarchical analysis. The testing results demonstrate the satisfactory capacity of the proposed MTI method in providing detailed subsidence information near MLs. | Tao Li Guoxiang Liu Hui Lin Rui Zhang Hongguo Jia Bing Yu | 2014 | Journal of Modern Transportation2014，22，3： | 4 |
| 7 | Monitoring subsidence rates along road network by persistent scatterer SAR interferometry with high-resolution TerraSAR-X imagery显示文摘Ground subsidence is one of the key factors damaging transportation facilities,e.g.,road networks consisting of highways and railways.In tiiis paper,we propose to apply the persistent scatterer synthetic aperture radar interferometry(PS-InSAR)approach mat uses highresolution TerraSAR-X(TSX)imagery to extract the regional scale subsidence rates(i.e.,average annual subsidence in mm/year)along road networks.The primary procedures involve interferometric pair selection,interferogram generation,persistent scatterer(PS)detection,PS networking,phase parameterization,and subsidence rate estimation.The Xiqing District in southwest Tianjin(China)is selected as the study area.This district contains one railway line and several highway lines.A total of 15TSX images covering this area between April 2009 and June 2010 are utilized to obtain the subsidence rates by using the PS-InSAR(PSI)approach.The subsidence rates derived from PSI range from—68.7 to—1.3 mm/year.These findings show a significantly uneven subsidence pattern along the road network.Comparison between the PSI-derived subsidence rates and the leveling data obtained along the highways shows that the mean and standard deviation(SD)of the discrepancies between die two types of subsidence rates are 0.1 and±3.2 mm/year,respectively.The results indicate that the high-resolution TSX PSI is capable of providing comprehensive and detailedsubsidence information regarding road networks with millimeter-level accuracy.Further inspections under geological conditions and land-use categories in the study area indicate that the observed subsidence is highly related to aquifer compression due to groundwater pumping.Therefore,measures should be taken to mitigate groundwater extraction for the study area. | Bing Yu Guoxiang Liu Rui Zhang Hongguo Jia Tao Li Xiaowen Wang Keren Dai Deying Ma | 2013 | Journal of Modern Transportation2013，21，4： | 4 |
| 8 | Morphology and magnetic properties of Sm_(2)Co_(7)/α-Fe nanocomposite magnets produced by high energy ball milling and spark plasma sintering显示文摘In this article,the Sm_(2)Co_(7)/α-Fe nanocomposite magnets were prepared by high energy ball milling and spark plasma sintering method.The effect of soft phase content on the magnetic properties was studied.Up to 30 wt% α-Fe was added into Sm_(2)Co_(7) matrix without the decrease of remanence.Optimal energy product(BH)max of 9.2 MGOe was obtained with 20 wt% α-Fe.TEM observation shows that the grain size of α-Fe is 20-50 nm which ensures a good coupling effect between soft and hard phase.One more thing needs to be mentioned is that there exists inter-diffusion between Sm-Co phase and α-Fe phase.Moreover,our results can also illustrate that the Sm_(2)Co_(7)/α-Fe nanocomposite magnets are able to acquire better magnetic properties than the SmCo_(5)/α-Fe magnets prepared by the same process due to the large domain width of Sm_(2)Co_(7) phase. | Yitong Zhuge Yuqing Li Xiaochang Xu Dongtao Zhang Hongguo Zhang Weiqiang Liu Ming Yue | 2021 | Journal of Rare Earths2021，39，3： | 3 |
| 9 | Ultrastructural changes in the optic nerve and capillary vessels during early stages of optic nerve injury显示文摘BACKGROUND:Capillaries are the only blood supply for optic nerves,which makes the system more vulnerable to impaired blood circulation.OBJECTIVE:To observe the ultrastructural changes in the optic nerves and capillaries in rabbits following intracanalicular segment injury to the optic nerve.DESIGN,TIME AND SETTING:Comparative,observational,pathological morphology was performed at the Department of Anatomy,Weifang Medical College from September to November 2007.MATERIALS:Models of intracanalicular segment injury to the optic nerve were induced in the right eye of thirty healthy,adult rabbits by a free-falling metal cylinder.The H-7500 transmission electron microscope was provided by Hitachi,Japan.METHODS:All rabbits were randomly assigned into experimental(n = 25) and control(n = 5) groups.Op-tic nerve specimens were obtained from the experimental group at 0.5,6,12,48,and 96 hours,respectively,following injury.Ultrastructural changes to the optic nerves and their capillaries were observed by electron microscopy.Optic nerve injury was not established in the control group,but optic nerve specimens were col-lected similarly to the experimental group.MAIN OUTCOME MEASURES:Ultrastructural changes in the injured optic nerves and their capillaries.RESULTS:Thirty rabbits were included in the final analysis.In the control group,cross-sections of the optic nerves exhibited varied thicknesses with regularly arranged fibers.The axons appeared to be smooth with condensed myelin sheaths and oval mitochondria.The microtubules and microfilaments were clearly seen.The lumens of the capillaries were regular with densely arranged endothelial cells and visible mitochondria.In the experimental group,30 minutes after injury to the optic nerves,swollen axons,sparse myelin sheath,disordered microtubules and microfilaments,swollen mitochondria,and a decreased number of pinocytosis vesicles and microfilaments in endothelial cells of the capillaries were observed.At 6 hours,medullary and vacuolar degeneration in the mitochondria,and swollen endothelial cells in the capillary,were visible.At 12 hours,these changes were more obvious.At 48 hours,granular dissolution of microtubules,microfilaments,and mitochondria,as well as diffuse degeneration of mitochondria in the endothelial cells,were observed.At 96 hours,axonal disintegration,vacuolar degeneration,and dilated capillaries were observed.CONCLUSION:During early stages,the injured intracanalicular optic nerve exhibited swollen axons with vacuolar degeneration,swollen and degenerated mitochondria,decreased number of microtubules and micro-filaments,and dilated capillaries with increased permeability. | Xuehong Ju Xiuyun Li Xiaoshuang Li Hongtao Tang Hongguo Liu | 2008 | Neural Regeneration Research2008，3，9： | 3 |
| 10 | CPTA treatment reveals potential transcription factors associated with carotenoid metabolism in flowers of Osmanthus fragrans显示文摘Osmanthus fragrans is one of the top ten traditional flowers in China.It is divided into three different groups according to its color.α-Carotene and β-carotene are the main determinants to distinguish the color differences between three groups.However,the dominant genes and transcription factors involved in carotenoid metabolism remain unclear.CPTA treatment(0.7mmol·L−1)remarkably promoted lycopene,α-carotene and β-carotene contents in flowers.Transcriptome sequencing analysis revealed that CPTA treatment could trigger chain reactions in carotenoid metabolism pathway genes.Four up-regulated and 10 down-regulated transcription factors which have close association with carotenoid variation were significantly induced by CPTA treatment.The up-regulated TFs such as MYB43,MYB123,HSF,were further subjected to transcript expression determination in different cultivars with drastic colors.Among them,transcript expression of four up-regulated TFs coincided with the carotenoid accumulation in different cultivars.We selected up-regulated OfMYB43 to verify its function,which is related to stress tolerance and transcriptional regulation.Transient overexpression of OfMYB43 in O.fragrans flowers showed that it could remarkably promote the expression of PDS,ZISO,LCYE and CCD4,leading to increased accumulation of β-branch carotenoids.OfMYB43 was a potential positive regulator of carotenoid biosynthesis in O.fragrans flowers.This study provides insight into the molecular mechanism of carotenoid metabolism in O.fragrans. | Wan Xi Yanhong He Linlin Zhu Shiyang Hu Shuyi Xiong Yi Zhang Jingjing Zou Hongguo Chen Caiyun Wang Riru Zheng | 2021 | Horticultural Plant Journal2021，7，5： | 3 |
| 11 | Strongly connected components based efficient computation of page rank显示文摘In this paper,an efficient page rank (PR)exact algorithm is proposed,which can improve the computation efficiency without sacrificing results accuracy.The existing exact algorithms are generally based on the original power method (PM).In order to reduce the number of I/Os required to improve efficiency,they partition the big graph into multiple smaller ones that can be totally fitted in memory.The algorithm proposed in this paper can further reduce the required number of I/Os.Instead of partitioning the graph into the general subgraphs,our algorithm partitions graph into a special kind of subgraphs:SCCs (strongly connected components), the nodes in which are reachable to each other.By exploiting the property of SCC,some theories are proposed,based on which the computation iterations can be constrained on these SCC subgraphs.Our algorithm can reduce lots of I/Os and save a large amount of computations,as well as keeping the results accuracy.In a word,our algorithm is more efficient among the existing exact algorithms.The experiments demonstrate that the algorithms proposed in this paper can make an obvious efficiency improvement and can attain high accurate results. | Hongguo YANG Derong SHEN Yue KOU Tiezheng NIE Ge YU | 2018 | Frontiers of Computer Science2018，12，6： | 2 |
| 12 | Theory of high-density low-cross-talk waveguide superlattices显示文摘Waveguide superlattices, a special type of waveguide arrays, can be designed to achieve very low cross talk at submicrometer/subwavelength pitches. The theoretical framework and design rationales for such waveguide superlattices will be presented in depth. Waveguide sidewall roughness can help to deter the coherent coupling between identical waveguides in nearby supercells, but it also induces random fluctuation of transmission.Statistical behavior of the transmission due to roughness in a waveguide superlattice is systematically treated.Complex transmission characteristics due to spectral oscillation and random roughness will be presented, and their evolution with the superlattice length will be analyzed. | Nan Yang Huashan Yang Hengrun Hu Rui Zhu Shining Chen Hongguo Zhang Wei Jiang | 2016 | Photonics Research2016，4，6： | 2 |
| 13 | Pathological changes in the retina and growth associated protein-43 expression following treatment of intracanalicular optic nerve injury via optic canal decompression,dexamethasone or their combination显示文摘BACKGROUND:The main clinical treatments for optic nerve injury are optic canal decompression and systemic administration of hormones,but both treatments have disadvantages.OBJECTIVE:To observe the pathological changes in the retina and growth associated protein-43(GAP-43) expression,to compare the treatment of optic canal decompression,hormones,and their combination with the intracanalicular optic nerve injury.DESIGN,TIME AND SETTING:A randomized,controlled animal study was performed at the Department of Anatomy,Weifang Medical University,China,from September 2007 to November 2008.MATERIALS:Dexamethasone(Shandong Huaxin Pharmaceutical,China) and rabbit anti-GAP-43 polyclonal antibody(Boster,China) were used.METHODS:All 36 healthy adult rabbits were randomly assigned to control group(n = 4),simple injury group(n = 20),and treatment group(n = 12).Intracanalicular optic nerve injury models were established using the metal cylinder free-fall impact method.The control group was left intact.The treatment group(four rabbits in each subgroup) was treated by optic nerve decompression,dexamethasone treatment(1 mg/kg daily via two intravenous infusions,1/5 total dose reduction every 3 days,for 14 days),and simultaneously giving surgery and hormone treatment.MAIN OUTCOME MEASURES:Pathological changes in the retina were determined using hematoxylin-eosin staining.GAP-43 expression was detected using immunohistochemistry in the retina.RESULTS:Retina injury induced obvious pathological changes in the retina.With prolonged time after optic nerve injury,the number of retinal ganglion cells was gradually decreased,and reached the minimum on day 14(P < 0.01).All three treatments increased the number of retinal ganglion cells(P < 0.01),but surgery + hormone treatment was most effective.No GAP-43 cells were present in the normal retinal,but they appeared 3 days after injury,peaked 7 days after injury,and then began to decline.CONCLUSION:Intracanalicular optic nerve injury induced obvious pathological changes in the retina,including increased GAP-43 expression.Optic canal decompression and hormones improved nerve repair after injury,and their combination produced better outcomes. | Xuehong Ju Hui Cheng Hongguo Liu Xiaoshuang Li Xiuyun Li | 2010 | Neural Regeneration Research2010，5，10： | 2 |
| 14 | Comparative catalytic study on butene/isobutane alkylation over LaX and CeX zeolites: The influence of calcination atmosphere显示文摘Lanthanum-containing(LaX)and cerium-containing X zeolites(CeX)were prepared by a doubleexchange,double-calcination method.By changing the calcination atmospheres between nitrogen and air,the Ce^(IV) contents in CeX zeolites were adjusted and their impacts on physicochemical properties and catalytic performance in isobutane alkylation were established.The crystallinity of CeX zeolite was found to be negatively correlated with the Ce^(IV) content.This i s believed to be due to the water formed during the oxidation of Ce^(III),which facilitates the framework dealumination.As a consequence,calcining in air resulted in a great elimination of strong Brønsted acid sites while under nitrogen protection,this phenomenon was mostly hindered and the sample’s acidity was preserved.When tested in a continuously flowed slurry reactor,the catalyst lifetime for isobutane alkylation was found to be linearly related to the strong Brønsted acid concentration.In addition,Ce^(3+)was found more benefit for the hydride transfer compared with La^(3+),which is ascribed to the stronger polarization effect on the CH bond of isobutane.Moreover,the decline of hydride transfer activity can be slowed down by the catalytic cracking of the bulky molecules.Based on the product distribution,a new catalytic cycle of dimethylhexanes(DMHs)involving a direct formation of isobutene rather than tert-butyl carbocation was proposed in isobutane alkylation. | Zhiqiang Yang Ruirui Zhang Honghua Zhang Hongguo Tang Ruixia Liu Suojiang Zhang | 2022 | Chinese Journal of Chemical Engineering2022，35，6： | 2 |
