比能法在渤海海峡隧道TBM 施工中的应用分析

高攀,邹翀

《中国工程科学》 2013年 第15卷 第12期   页码 73-79

摘要：

拟建的渤海海峡隧道采用隧道掘进机（TBM）施工极具挑战性，其中关键之一就是TBM的掘进速率预测问题。本文将渤海海峡隧道和澳大利亚Clem Jones 隧道进行工程类比，并介绍了比能法在Clem Jones 隧道的应用情况。在Clem Jones 隧道施工过程中，相关研究人员运用比能法对TBM的可掘性进行了分析及预测，从后期的掘进情况来看比能法的预测结果与实际施工吻合得较好。本文在Clem Jones 隧道和渤海海峡隧道对比分析的基础上，认为运用比能法预测TBM的可掘性同样适用于渤海海峡隧道的TBM施工。

Hamed MANSOORI, Parviz Rezvani MOGHADDAM, Rooholla MORADI

《能源前沿（英文）》 2012年 第6卷 第4期   页码 341-350 doi: 10.1007/s11708-012-0206-x

摘要： Compared to conventional agriculture, organic agriculture is reported to be more efficient and effective in reducing water and soil pollution, greenhouse gases (GHGs) emission and risk of human health. In additional, field management under organic condition can be useful for increasing energy efficiency. Rice is one of the important crops which are cultivated in two forms, organic and conventional, in Iran. In order to compare the energy efficiency and economic analysis of rice production in organic and conventional systems in Iran, needed information was collected by face-to-face questionnaire in 2011 and three scenarios were designed to predict the changes of energy budget and economic analysis in the transition period that included: 25%, 50% and 75% organic management in rice production. The results showed that all energy indexes were improved in organic rice production compared to conventional condition. Higher values of benefit to cost ratio, gross and net return and lower value of total cost of production were obtained from organic rice production which indicated that the organic management of farm improved economically in comparison with the conventional rice production system. The shares of direct and renewable energies were increased by approach to organic management. Increase in energy efficiency and productivity was predicted for the transition period but decrease trend in economic indexes was projected for this period in all scenarios. The main reason for decreasing economic indexes in organic scenarios was that the market price of organic rice was the same as that of conventional rice in the transition period.

Studies of ultrasound disintegration of residual sludge and its energy consumption in water treatment

SHEN Jinfeng, YIN Xuan, GU Heping, Lv Xiaoping

《化学科学与工程前沿（英文）》 2007年 第1卷 第4期   页码 395-398 doi: 10.1007/s11705-007-0072-y

摘要： To investigate the influence of ultrasound pretreatment on sludge anaerobic digestion, the ultrasound disintegration of residual sludge in water treatment of petrochemical plant was studied, and the mechanisms of ultrasound and medium were introduced. Experimental results indicate that ultrasound cavitation induces the rise of sludge temperature, which improves ultrasound disintegration on sludge. U1trasound pretreatment can advance observably the quantity of chemical oxygen demand in sludge supernatant fluid (SCOD), which increases with ultrasound intensity and sonication time. The degree of ultrasound disintegration increases with the specific energy input. When the specific energy input is l0 000 kJ/kg of total dry solids, the degree of ultrasonic sludge disintegration reaches 40%.

Characteristic and correlation analysis of influent and energy consumption of wastewater treatment plants

Luxi Zou, Huaibo Li, Shuo Wang, Kaikai Zheng, Yan Wang, Guocheng Du, Ji Li

《环境科学与工程前沿（英文）》 2019年 第13卷 第6期 doi: 10.1007/s11783-019-1167-7

摘要： Poor biodegradability and insufficient carbon source are discovered from influent. Influent indices presented positively normal distribution or skewed distribution. Average energy consumption of WWTPs in Taihu Basin was as high as 0.458 kWh/m3. Energy consumption increases with the increase in influent volume and COD reduction. The total energy consumption decreases with the NH3-N reduction. 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/m3. The specific energy consumption of WWTPs with a daily treatment capacity of more than 5 × 104 m3 in Taihu Basin was stable at 0.33 kWh/m3. 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.

基于纳米孔渗透获取盐度梯度能量发电的可行性研究 Article

王樟新, Li Wang, Menachem Elimelech

《工程（英文）》 2022年 第9卷 第2期   页码 51-60 doi: 10.1016/j.eng.2021.02.016

摘要：

随着具有离子选择性纳米通道的新型材料的研发，一种获取盐度梯度（蓝色）能量的新技术被提出，即纳米孔发电机（NPG）。在本研究中，我们对膜片尺度和组件尺度的NPG运行的实际性能进行了全面分析。结果表明，虽然NPG 膜片可以在理想条件下产生超高的功率密度，但由于浓度极化效应，实际运行中NPG膜片上产生的功率密度很难达到10 W·m−2。对于组件尺度的NPG运行，我们估算了功率密度和可提取比能（即使用单位总体积工作溶液可产生的能量），并基于浓度极化与高浓度溶液和低浓度溶液的混合程度之间的相互作用，阐明运行条件对这两个指标的影响。此外，我们还开发了一个用来评估NPG 系统可行性的模型框架。结果表明，对于使用海水与河水的NPG 系统，总可提取比能非常低（约0.1 kW·h·m−3），且受到系统运行能耗的影响（特别是海水和河水溶液的汲取与预处理能耗）。总的来说，NPG系统产生的净可提取比能（< 0.025 kW·h·m−3）和净功率密度（< 0.1 W·m−2）非常低。我们的研究重点指出了NPG在现实运行中存在极大的局限性，进而对NPG作为一种蓝色能量收集技术的可行性提出了质疑。

Influence of sprinkler irrigation droplet diameter, application intensity and specific power on flower

Yisheng ZHANG, Delan ZHU

《农业科学与工程前沿（英文）》 2017年 第4卷 第2期   页码 165-171 doi: 10.15302/J-FASE-2017145

摘要： To determine the main parameters of droplet strike damage and avoid flower injury due to the unsuitable practices during sprinkler irrigation, an indoor experiment of irrigation droplet impact on cyclamen was conducted. The influences of different parameters such as droplet diameter, application intensity, specific power on flower strike damage was analyzed using Image Pro-Plus software to compute strike damage area and define damage level by sense-analysis. The results showed that a damage area of <1% represents a safe irrigation level, 1%–3% slight damage level, 3%–6% moderate damage level, and>6% heavy damage level. Equations of application intensity, specific power with sprinkler irrigation time and flower injury ratio were regressed against parameters which cause impact damages. The results indicated that specific power has a significant correlation with injury, and flower damage area increased as the increasing of the value of specific power for the same irrigation time. Application intensity was also correlated with injury when the droplet diameter was larger than 1 mm. When the duration of sprinkler irrigation was 1, 5 and 10 min, the threshold of impinging damage of application intensity was 25.30, 5.01 and 1.64 mm·h and the specific power was 0.467×10 , 9.340×10 and 3.110×10 W·m . These results provide a reference for determining the suitable values of sprinkler properties in operation design.

An integrated approach to site-specific management zone delineation

Yuxin MIAO, David J. MULLA, Pierre C. ROBERT

《农业科学与工程前沿（英文）》 2018年 第5卷 第4期   页码 432-441 doi: 10.15302/J-FASE-2018230

摘要：

Dividing fields into a few relatively homogeneous management zones (MZ) is a practical and cost-effective approach to precision agriculture. There are three basic approaches to MZ delineation using soil and/or landscape properties, yield information, and both sources of information. The objective of this study is to propose an integrated approach to delineating site-specific MZ using relative elevation, organic matter, slope, electrical conductivity, yield spatial trend map, and yield temporal stability map (ROSE-YSTTS) and evaluate it against two other approaches using only soil and landscape information (ROSE) or clustering multiple year yield maps (CMYYM). The study was carried out on two no-till corn-soybean rotation fields in eastern Illinois, USA. Two years of nitrogen (N) rate experiments were conducted in Field B to evaluate the delineated MZs for site-specific N management. It was found that in general the ROSE approach was least effective in accounting for crop yield variability (8.0%–9.8%), while the CMYYM approach was least effective in accounting for soil and landscape (8.9%–38.1%), and soil nutrient and pH variability (9.4%–14.5%). The integrated ROSE-YSTTS approach was reasonably effective in accounting for the three sources of variability (38.6%–48.9%, 16.1%–17.3% and 13.2%–18.7% for soil and landscape, nutrient and pH, and yield variability, respectively), being either the best or second best approach. It was also found that the ROSE-YSTTS approach was effective in defining zones with high, medium and low economically optimum N rates. It is concluded that the integrated ROSE-YSTTS approach combining soil, landscape and yield spatial-temporal variability information can overcome the weaknesses of approaches using only soil, landscape or yield information, and is more robust for MZ delineation. It also has the potential for site-specific N management for improved economic returns. More studies are needed to further evaluate their appropriateness for precision N and crop management.

Application of StrucGP in medical immunology: site-specific -glycoproteomic analysis of macrophages

《医学前沿（英文）》 2023年 第17卷 第2期   页码 304-316 doi: 10.1007/s11684-022-0964-8

摘要： The structure of N-glycans on specific proteins can regulate innate and adaptive immunity via sensing environmental signals. Meanwhile, the structural diversity of N-glycans poses analytical challenges that limit the exploration of specific glycosylation functions. In this work, we used THP-1-derived macrophages as examples to show the vast potential of a N-glycan structural interpretation tool StrucGP in N-glycoproteomic analysis. The intact glycopeptides of macrophages were enriched and analyzed using mass spectrometry (MS)-based glycoproteomic approaches, followed by the large-scale mapping of site-specific glycan structures via StrucGP. Results revealed that bisected GlcNAc, core fucosylated, and sialylated glycans (e.g., HexNAc4Hex5Fuc1Neu5Ac1, N4H5F1S1) were increased in M1 and M2 macrophages, especially in the latter. The findings indicated that these structures may be closely related to macrophage polarization. In addition, a high level of glycosylated PD-L1 was observed in M1 macrophages, and the LacNAc moiety was detected at Asn-192 and Asn-200 of PD-L1, and Asn-200 contained Lewis epitopes. The precision structural interpretation of site-specific glycans and subsequent intervention of target glycoproteins and related glycosyltransferases are of great value for the development of new diagnostic and therapeutic approaches for different diseases.

摘要： The aim of this paper is to construct a specific and high-performance gene therapy system for glioma. We constructed a combined promoter 6HRE-GFAP (Hypoxia Responsive Element, Glial Fibrillary Acidic Protein) by gene recombination techniques according to the hypoxia microenvironment in glioma and tested its efficacy and specificity in cultured cells, and then constructed GFAP-Baxα gene expressing system and determined its promoting of apoptosis in glioma cells. Our primary results showed that in U251 and BT325 cell lines, the activity of GFAP promoter was 16.40 and 4.73-fold of the promoter of hTERT (Human Telomerase Reverse Transcriptase), respectively. The activities of 6HRE-GFAP-promoter increased by 3.08 and 1.30-fold under 2% O condition compared with those under 18% O condition, while under 0.2% O condition increased by 8.90 and 2.69-fold, respectively. The glioma cells showed typical apoptotic signs 90 hours after the transient transfection of GFAP-Baxα. In these primary experiments, it showed that 6HRE-GFAPBaxα system could promote glioma cell apoptosis. It was specific and effective for glioma gene therapy.

《医学前沿（英文）》 2007年 第1卷 第3期   页码 253-257 doi: 10.1007/s11684-007-0048-9

摘要： The purpose of this work was to construct the plasmid that could direct the synthesis of siRNA-like transcripts and thus mediate strong and specific repression of human heat shock protein 90β (Hsp90β) gene expression and to compare the transfection efficiency of the plasmids in varying conditions of transfection. Three 64 nt oligos corresponding to different regions of the target gene were chemically synthesized and annealed and were then ligated with pSUPER EGFP1 plasmid and double-digested with HindIII and Π. Recombinant plasmids were transformed into , DH5a, and the colonies were picked and grown in the Amp-agarose. The presence of positive clones was checked by the means of endodigestion and sequencing. Three cell strains, HepG2, Human umbilicus vein endothelium cells (HUVEC) and HeK293, were cultured. Then the plasmids were transfected into the cells at different ratios of plasmid to Lipofectamine. The transfection efficiency was measured by detection of enhanced green fluorescence protein (EGFP). The presence of positive recombinant clones were verified by double-digestion and sequencing. The bases inserted into the plasmids were correct and the positive colonies were named pSuper-Hsp90β1, pSuper-Hsp90β2 and pSuper-Hsp90β3. After optimizing the ratio of plasmid to Lipofectamine, we achieved high transfection efficiency in HeK293 cells. Transfection efficiency was still low in the HepG2 cells. In conclusion, the si-RNA-synthesizing plasmids targeting Hsp90β were constructed and transfected into cells with different transfection efficiency.

《化学科学与工程前沿（英文）》 2010年 第4卷 第1期   页码 52-56 doi: 10.1007/s11705-009-0301-7

摘要： In this paper, the research framework for specific structure crystallization modeling has been proposed in which four steps are required in order to investigate the rigorous crystallization modeling by thermodynamics. The first is the activity coefficient model of the solution, the second is Solid-Liquid equilibrium, the third and fourth are the dissolution and crystallization kinetics modeling, respectively. Our investigations show that the mechanisms of complex structure formation and microphase transition can be analyzed by combining the dissolution and crystallization kinetics modeling. Moreover, the formation mechanism of the porous KCl has been analyzed, which may provide a reference for the porous structure formation in the advanced material synthesis.
