| 1 | Characteristic and correlation analysis of influent and energy consumption of wastewater treatment plants in Taihu Basin显示文摘The water quality and energy consumption of wastewater treatment plants(WWTPs)in Taihu Basin were evaluated on the basis of the operation data from 204 municipal WWTPs in the basin by using various statistical methods.The influent ammonia nitrogen(NH3-N)and total nitrogen(TN)of WWTPs in Taihu Basin showed normal distribution,whereas chemical oxygen demand(COD),biochemical oxygen demand(BOD5),suspended solid(SS),and total phosphorus(TP)showed positively skewed distribution.The influent BOD5/COD was 0.4%-0.6%,only 39.2%SS/BOD5 exceeded the standard by 36.3%,the average BOD5/TN was 3.82,and the probability of influent BOD5/TP>20 was 82.8%.The average energy consumption of WWTPs in Taihu Basin in 2017 was 0.458 kWh/m^3.The specific energy consumption of WWTPs with a daily treatment capacity of more than 5×10^4 m^3 in Taihu Basin was stable at 0.33 kWh/m^3.A power function relationship was observed between the reduction in COD and NH3-N and the specific energy consumption of pollutant reduction,and the higher the pollutant reduction is,the lower the specific energy consumption of pollutant reduction presents.In addition,a linear relationship existed between the energy consumption of WWTPs and the specific energy consumption of influent volume and pollutant reduction.Therefore,upgrading and operation with less energy consumption of WWTPs is imperative and the suggestions for Taihu WWTPs based on stringent discharge standard are proposed in detail. | Luxi Zou Huaibo Li Shuo Wang Kaikai Zheng Yan Wang Guocheng Du Ji Li | 2019 | Frontiers of Environmental Science & Engineering2019，13，6： | 2 |
| 2 | Optimal remote radio head selection for cloud radio access networks显示文摘The cloud radio access network(C-RAN) promises significant gain to the data rate over the LTEadvanced by transferring the burdensome baseband signal processing from the remote radio heads(RRHs) to the baseband unit via the front-haul. However, scalable improvement of the overall throughput may not be maintained due to limited front-haul capacity. In this paper, we study the throughput maximization problem by selecting the active RRHs. In particular, we develop an optimum algorithm which selects a subset of active RRHs that maximize the system throughput under the front-haul constraint. In addition, the asymptotically optimum number of RRHs is derived in closed-form for low and high signal-to-noise ratio(SNR) regimes. It is demonstrated that the proposed RRH selection scheme outperforms any other existing schemes with substantial gain of achievable throughput for any given number of RRHs and any predetermined front-haul capacity constraints. | Chunguo LI Kang SONG Dongming WANG Fu-Chun ZHENG Luxi YANG | 2016 | Science China(Information Sciences)2016，59，10： | 1 |
| 3 | Isolation and Identification of Pathogenic Fungi in Kiwifruit during the Storage Period显示文摘[Objectives]The paper was to identify the pathogenic species of postharvest diseases of kiwifruit.[Methods]The pathogenic fungi were isolated from diseased kiwifruits during the storage period,and cultured to observe their culture traits and morphological characteristics.Molecular biological identification and pathogenicity test were carried out to confirm the main pathogens.[Results]There were 7 species of pathogenic fungi causing kiwifruit diseases during the storage period,including Alternaria spp.,Botryosphaeria dothidea,Phomopsis/Diaporthe spp.,Pestalotiopsis sp.,Pseudocercospora sp.,Colletotrichum sp.,and Botrytis cinerea.[Conclusions]The research will provide a scientific basis for the prevention and control of postharvest diseases of kiwifruit. | Baolin SHAO Luxi LIU Baiyu SU Yifen YANG Ying ZHANG Fang LIAO Aiping ZHENG | 2022 | Plant Diseases and Pests2022，13，4： | 0 |
| 4 | Protective effects of Dioscin on TNF-α-induced collagen-induced arthritis rat fibroblast-like synoviocytes involves in regulating the LTB4/BLT pathway显示文摘Background and Objective:LTB4 has been shown to be involved in rheumatoid arthritis(RA)pathogenesis.The effect of Dioscin(Dio)on the LTB4 pathway of RA have not been reported yet.This study aimed at further exploring whether Dioscin’s effects on TNF-αinduced collagen-induced arthritis(CIA)rat fibroblast-like synoviocytes(FLS)connected with the LTB4 and its receptor pathway.Materials&Methods:In this experiment,control group,TNF-αgroup,and different concentrations of Dioscin groups were established.Cell viability was evaluated using MTT assay.The levels of LTB4 in the samples of above groups were measured using ELISA.The mRNA expression levels of LTA4H,BLT1,and BLT2 were detected by quantitative real time PCR,while the expression level of LTA4H proteins were detected using western blot.The distribution of LTA4H was assessed by immunofluorescence assay.Results:the LTB4 level of TNF-αgroup in sample supernatant was higher than both control group and Dioscin groups with decreased LTB4 levels(p<0.05).Compared with the control group,the expression of LTA4H was significantly increased in TNF-αgroup(p<0.05),whereas LTA4H expressions were significantly decreased in all Dioscin groups when compared to TNF-αgroup(p<0.05).The mRNA expressions of BLT1 and BLT2 were markedly higher in TNF-αgroup than those in control group while Dioscin treatment significantly inhibited the increased expressions of BLT1 and BLT2 induced by TNF-α(p<0.05).Conclusions:These results firstly demonstrate that the protective effect of Dioscin on TNF-αinduced FLS may involve in its reducing LTB4 production by down-regulating LTA4H expression,and may inhibit its downstream pathway by decreasing LTB4 receptors levels.This findings suggest that dioscin produces a potential therapeutic effects for RA via its influencing LTA4H/LTB4/BLT pathway. | ZHIPING WEI YAJUN LIU MEIWEN YANG MENGDI LI KEXIN LI LUXI ZHENG HUIQIONG GUO FENFANG HONG SHULONG YANG | 2021 | BIOCELL2021，45，4： | 0 |
