Understanding barriers to BIM implementation: Their impact across organizational levels in relation to

Sander SIEBELINK, Hans VOORDIJK, Maaike ENDEDIJK, Arjen ADRIAANSE

《工程管理前沿（英文）》 2021年 第8卷 第2期   页码 236-257 doi: 10.1007/s42524-019-0088-2

摘要： This multiple case study of a contracting firm contributes to understanding the barriers that organizations face during the implementation of building information modeling (BIM) by providing insights into the impact of these barriers across different organizational levels (i.e., from top management to project teams) and by relating these barriers to different degrees of BIM maturity. First, we observe the dominance of barriers related to the motivation, competence, and time capacity of people across all levels of an organization. Second, the cluster of barriers at the middle-management level highlights the important role of this level in reducing these barriers. Third, only those cases with a low level of BIM maturity have struggled with lack of top management support, thereby highlighting the importance of such support in achieving BIM maturity growth. High BIM maturity situations are more prone to externally oriented barriers in attempting to further leverage the benefits of BIM. Our study provides insights on where to focus BIM implementation measures and how to enhance organizational BIM maturity.

Elevated C-reactive protein levels predict worsening prognosis in Chinese patients with first-onset stroke

Jiangtao YAN, Rutai HUI, Daowen WANG

《医学前沿（英文）》 2009年 第3卷 第1期   页码 30-35 doi: 10.1007/s11684-009-0005-x

摘要： The role of high sensitivity C-reactive protein (hsCRP) in predicting prognosis after stroke in the Asian population has not been investigated. We hypothesized that elevated levels of hsCRP were associated with worsening prognosis after stroke in Chinese patients. Two hundred and ninety consecutive patients with first-onset stroke and 290 age- and gender-matched control subjects without any cerebrovascular disease were enrolled for study. Plasma hsCRP level was detected and subsequent vascular events and death were recorded in both groups over a 5-year period. Compared to control group, patients presenting with stroke had higher plasma hsCRP level (3.3 ± 3.8 1.3 ± 2.2 mg/L, < 0.01). Furthermore, in the group of patients with stroke, the mean plasma hsCRP level was higher in patients who developed subsequent vascular diseases or died as compared with the patients without further complications (4.4 ± 4.3 2.7 ± 3.3 mg/L, < 0.01). Compared to the lowest tertile of hsCRP level, the relative risk for vascular events or death in stroke patients was 2.91 in the highest tertile of hsCRP (95% CI, 1.54–5.50, = 0.001). This increase in relative risk for vascular events or death in stroke patients continued after adjustment for age, sex and other cardiovascular risk factors such as hypertension and diabetes ( : 2.771, 95% CI: 1.367–5.617, = 0.005). These findings indicate that increased hsCRP level is associated with worsening prognosis after stroke in Chinese patients and suggests that inflammation is correlated with stroke outcome.

Effect of eccentricity in reinforced concrete beam-column-slab connection under cyclic loading

Rooh ULLAH, Amjad NASEER, Muhammad FAHIM, Mohammad ASHRAF, Eid BADSHAH

《结构与土木工程前沿（英文）》 2021年 第15卷 第2期   页码 390-398 doi: 10.1007/s11709-021-0690-3

摘要： Beam–column connections are one of the most critical elements of reinforced concrete structures, especially in seismically active regions, and have been extensively evaluated experimentally and numerically. However, very limited experimental studies about eccentric reinforced concrete connections including the effect of connected slabs are available. This study presents the experimental results of two half-scale eccentric beam-column-slab connections subjected to quasi-static cyclic loading. The horizontal eccentricity ( ) is maintained at 12.5% and 25% of column width ( ) for specimens 1 and 2, respectively. The damage pattern, performance levels, displacement ductility ( ), energy dissipation, and connection strength and stiffness are compared for both specimens, and the effect of eccentricity is evaluated. It is concluded that the eccentricity has no significant effect on the lateral load carrying capacity; however, the overall strength degradation increases with the increase in eccentricity. Similarly, the elastic stiffness of specimen 2 decreased by 14% as the eccentricity increased from 12.5% to 25%; however, the eccentricity had no significant effect on the overall stiffness degradation. decreased by 43%, and the energy dissipation capacity decreased by 40% in specimen 2 with higher eccentricity. The story drifts corresponding to the performance levels of the life safety (LS) and collapse prevention (CP) were found to be 28% lesser in specimen 2 than in specimen 1.

Improving the efficiency and effectiveness of global phosphorus use: focus on root and rhizosphere levels

摘要：

Phosphorus (P) is essential for life and for efficient crop production, but global P use with limited recycling is inefficient in several sectors, including agronomy. Unfortunately, plant physiologists, agronomists, farmers and end users employ different measures for P use efficiency (PUE), which often masks their values at different scales. The term P use effectiveness, which also considers energetic and sustainability measures in addition to P balances, is also a valuable concept. Major physiological and genetic factors for plant P uptake and utilization have been identified, but there has been limited success in genetically improving PUE of modern crop cultivars. In maize, studies on root architectural and morphological traits appear promising. Rhizosphere processes assist in mobilizing and capturing sparingly soluble phosphate from rock phosphate. Combinations of phosphate-solubilizing microorganisms with ammonium-based nitrogen fertilizer, as well as strategies of fertilizer placement near the roots of target crops, can moderately enhance PUE. The desired concentration of P in the products differs, depending on the final use of the crop products as feed, food or for energy conversion, which should be considered during crop production.

Predicting the response of continuous RC deep beams under varying levels of differential settlement

M. Z. NASER, R. A. HAWILEH

《结构与土木工程前沿（英文）》 2019年 第13卷 第3期   页码 686-700 doi: 10.1007/s11709-018-0506-2

摘要： This paper investigates the effect of differential support settlement on shear strength and behavior of continuous reinforced concrete (RC) deep beams. A total of twenty three-dimensional nonlinear finite element models were developed taking into account various constitutive laws for concrete material in compression (crushing) and tension (cracking), steel plasticity (i.e., yielding and strain hardening), bond-slip at the concrete and steel reinforcement interface as well as unique behavior of spring-like support elements. These models are first validated by comparing numerical predictions in terms of load-deflection response, crack propagation, reaction distribution, and failure mode against that of measured experimental data reported in literature. Once the developed models were successfully validated, a parametric study was designed and performed. This parametric study examined number of critical parameters such as ratio and spacing of the longitudinal and vertical reinforcement, compressive and tensile strength of concrete, as well as degree (stiffness) and location of support stiffness to induce varying levels of differential settlement. This study also aims at presenting a numerical approach using finite element simulation, supplemented with coherent assumptions, such that engineers, practitioners, and researchers can carry out simple, but yet effective and realistic analysis of RC structural members undergoing differential settlements due to variety of load actions.

《医学前沿（英文）》 2008年 第2卷 第1期   页码 5-10 doi: 10.1007/s11684-008-0002-5

摘要： We assessed the secular trends in the serum lipid levels in Shanghai residents from 1973 to 1999. Data from four independent, cross-sectional, population-based surveys were used to analyze the trends in serum lipid levels from 1973 to 1999. A standard protocol was applied across each survey in at least three independent surveys which were separated a 10-year study period. A total of 10733 (1385, 3302, 2399, and 3647 subjects who had complete data on serum lipids in 1973–1974, 1982, 1983 and 1997–1999, respectively) Shanghai residents aged from newborn to 80 years old were enlisted at random. Serum lipid levels were measured in a single laboratory throughout the entire study period. A non-significant increase was noted from 1973–1974 to 1982–1983 in the serum lipid profiles; however, a significant increase was observed from 1982–1983 to 1997–1999 in most of the age groups of both sexes. Mean serum total cholesterol (TC) levels increased significantly ( < 0.05) over the entire study period (overall period covered: 1973–1999) in most age groups of both sexes. In males, the changes were from 7.3% to 23.2% and in females, from 9.0% to 21.6%, except in umbilical blood samples and in females over 60 years where insignificant results were observed. Similar trends were observed in the mean serum triglyceride (TG) and the mean serum low-density lipoprotein cholesterol (LDL-c) levels, both in females and males. The majority show an upward trend. As for TGs, the changes were from 27.5% to 82.7% in males and from 13.2% to 54.6% in females. As for LDL-c the changes were from 34.9% to 71.0% in males and from 31.9% to 63.6% in females. Mean serum high-density lipoprotein cholesterol (HDL-c) levels were decreased significantly from 1982–1983 to 1997–1999, with the changes from -13.2% to -38.6% in males and from -9.8% to -21.7% in females. The ratio of total cholesterol to high-density lipoprotein cholesterol (TC/HDL-c) increased dramatically during this period because of a concurrent decline in the levels of HDL-c and the increase in the levels of TC. The prevalence of hypercholesterolemia (To achieve the normal range of serum TC and TG in healthy people of Shanghai, we determined the cut-off point in the cumulative frequency curve as the 95% percentile of the data collected by the survey in 1973–1974. The results show that the 95% cut-off point for TC was 220 mg/dL, while for TG, it was 160 mg/dL.) increased significantly ( < 0.05). In males aged 20 to 40 years old, the prevalence of hypercholesterolemia was from 1.6% to 7.79%, and in ages> 40 it was from 5.5% to 11.57%. In females, it was 0 to 4.68% and 6.5% to 16.2%, respectively. In general, the trends in the levels of TC, TG and LDL-c were increasing and trends in the levels of HDL-c were decreasing in most age groups, especially, in the younger age group of Shanghai residents from 1980s to 1990s. These worrying findings are significant for its public health implications. Health education and health promotion are necessary to prevent the disease prevalence from rising in the Chinese population.

Nutrient status and pollution levels in five areas around a manganese mine in southern China

Kehui Liu, Xiaolu Liang, Chunming Li, Fangming Yu, Yi Li

《环境科学与工程前沿（英文）》 2020年 第14卷 第6期 doi: 10.1007/s11783-020-1279-0

摘要： Abstract • The soil TP level was high or extremely high in all areas. • TN, OM and available Cu were insufficient in EA, TA and RA. • All areas reached the heavily polluted level and had high ecological risk levels. • Mn and Cd were the dominant pollutants. Nutrient status and pollution levels are the main factors affecting soil restoration. The nutrient status and pollution levels in five areas, an unexplored mine area (UA), an explored mine area (EA), a tailings area (TA), a reclamation area (RA) and an agricultural area (AA), around the Pingle manganese mine in Guangxi, China, were assessed in this study. The results showed that the average total phosphorus in these five areas ranged from 1.05 to 1.57 mg/kg, corresponding to grades of extremely high and high. The average total nitrogen values were 0.19, 0.69, 0.93, 1.24 and 1.67 mg/kg in EA, TA, RA, UA and AA, corresponding to grades of very low, low, medium-low, medium-high and medium-high, respectively. The average organic matter values were 12.78, 8.92, 22.77, 21.29 and 29.11 mg/kg in EA, TA, RA, UA and AA, which corresponded to grades of medium-low, low, medium-high, medium-high and medium-high, respectively. All these results indicated that the total phosphorus was sufficient in these areas, while the total nitrogen and organic matter were insufficient in EA, TA and RA. The available concentrations of Mn and Zn corresponded to the intermediate grade, while the values for Cu corresponded to the very low grade; these might be another factor restricting ecological reclamation. Contamination and ecological risk assessments based on the single contamination index, Nemerow multi-factor index and potential ecological risk index showed that the five tested areas around the Mn mine were considered heavily polluted and presented high ecological risk. Mn and Cd were the dominant pollutants.

《医学前沿（英文）》 2008年 第2卷 第3期   页码 276-282 doi: 10.1007/s11684-008-0052-8

摘要： In this study, the serum levels, including thyroid hormones free triiodothyronine (FT), free thyroxine(FT),thyroid stimulating hormone(TSH)among the subjects from the exposed group ( = 48) and the control group ( = 45) were detected by immuno radiometric assay (IRMA). The expression levels of TR?1, TR?1, TSHR mRNA in placentas and umbilical cords were detected by fluorescent quantitative real-time PCR (FQ-PCR). The correlations between the thyroid hormone levels in maternal serum and umbilical serum, and between the expression levels of its receptors mRNA in placentas and umbilical cords were determined. We found that the FT levels of both maternal serum and umbilical cord serum in the exposed group were lower than those in the control ( < 0.05). However, the increased TSH levels in the exposed group had statistically significance compared to those in the control group ( < 0.05). The TR?1 and TR?1 mRNA levels both in placentas and umbilical cords in the exposed group were lower than those in the control group ( < 0.05 and 0.01). However, the TSHR mRNA levels in the exposed group were significantly different compared to those in the control group ( < 0.01). The serum FT4 and TSH levels of parturient women were positively correlated with those of the newborns in both groups ( < 0.05 and 0.01). The mRNA levels of TR?1, TR?1 and TSHR in the placentas were positively correlated with those in umbilical cords in both groups ( < 0.01). The findings suggest that some environmental pollutants existing in the electronic waste (e-waste) dismantling region may affect the health of local parturient women and newborns, representing changes both in serum levels of thyroid hormones and in mRNA expression of its receptors.

Tramadol reinforces antidepressant effects of ketamine with increased levels of brain-derived neurotrophic

null

《医学前沿（英文）》 2012年 第6卷 第4期   页码 411-415 doi: 10.1007/s11684-012-0226-2

摘要：

Ketamine exerts rapid and robust antidepressant properties in both animal models and depressed patients and tramadol possesses potential antidepressant effects. Brain-derived neurotrophic factor (BDNF) is an important biomarker for mood disorders and tropomyosin-related kinase B (TrkB) is a high affinity catalytic receptor for BDNF. We hypothesized that tramadol pretreatment might reinforce ketamine-elicited antidepressant effects with significant changes in hippocampal BDNF and TrkB levels in rats. Immobility time of rats receiving different treatment in the forced swimming test (FST) was observed. Levels of BDNF and TrkB in hippocampus were measured by enzyme linked immunosorbent assay. Results showed that tramadol (5 mg/kg) administrated alone neither elicited antidepressant effects nor altered BDNF or TrkB level. However, pretreatment with tramadol (5 mg/kg) enhanced the ketamine (10 mg/kg) -elicited antidepressant effects and upregulated the BDNF and TrkB levels in hippocampus. In conclusion, tramadol pretreatment reinforces the ketamine-elicited antidepressant effects, which is associated with the increased levels of BDNF and TrkB in rat hippocampus.

Downregulation effects of beta-elemene on the levels of plasma endotoxin, serum TNF-alpha, and hepatic

null

《医学前沿（英文）》 2011年 第5卷 第1期   页码 101-105 doi: 10.1007/s11684-011-0111-4

摘要：

It has been demonstrated that β-elemene could protect against carbon tetrachloride (CCl4)-induced liver fibrosis in our laboratory work, and the aim of this paper is to reveal the protective mechanisms of β-elemene. The hepatic fibrosis experimental model was induced by the hypodermical injection of CCl4 in Wistar male rats. β-elemene was intraperitoneally administered into rats for 8 weeks (0.1 mL/100 g bodyweight per day), and plasma endotoxin content was assayed by biochemistry. The serum TNF-α level was detected using radioactive immunity. CD14 expression in rat livers was measured by immunohistochemistry and Western blot. The results showed that β-elemene can downregulate the levels of plasma endotoxins, serum TNF-α, and hepatic CD14 expression in rats with liver fibrosis. β-elemene plays an important role in downregulating the lipopolysaccharide signal transduction pathway, a significant pathway in hepatic fibrosis development.

Concentration levels of disinfection by-products in 14 swimming pools of China

Xiaolu ZHANG,Hongwei YANG,Xiaofeng WANG,Yu ZHAO,Xiaomao WANG,Yuefeng XIE

《环境科学与工程前沿（英文）》 2015年 第9卷 第6期   页码 995-1003 doi: 10.1007/s11783-015-0797-7

摘要： Swimming has become a popular exercising and recreational activity in China but little is known about the disinfection by-products (DBPs) concentration levels in the pools. This study was conducted as a survey of the DBPs in China swimming pools, and to establish the correlations between the DBP concentrations and the pool water quality parameters. A total of 14 public indoor and outdoor pools in Beijing were included in the survey. Results showed that the median concentrations for total trihalomethanes (TTHM), nine haloacetic acids (HAA9), chloral hydrate (CH), four haloacetonitriles (HAN4), 1,1-dichloropropanone, 1,1,1-trichloropropanone and trichloronitromethane were 33.8, 109.1, 30.1, 3.2, 0.3, 0.6 µg?L and below detection limit, respectively. The TTHM and HAA9 levels were in the same magnitude of that in many regions of the world. The levels of CH and nitrogenous DBPs were greatly higher than and were comparable to that in typical drinking water, respectively. Disinfection by chlorine dioxide or trichloroisocyanuric acid could substantially lower the DBP levels. The outdoor pools had higher TTHM and HAA9 levels, but lower trihaloacetic acids (THAA) levels than the indoor pools. The TTHM and HAA9 concentrations could be moderately correlated with the free chlorine and total chlorine residuals but not with the total organic carbon (TOC) contents. When the DBP concentration levels from other survey studies were also included for statistical analysis, a good correlation could be established between the TTHM levels and the TOC concentration. The influence of chlorine residual on DBP levels could also be significant.

《医学前沿（英文）》 2018年 第12卷 第6期   页码 697-706 doi: 10.1007/s11684-018-0655-7

摘要：

Oxidative stress induced by free fatty acid aggravates endothelial injury, which leads to diabetic cardiovascular complications. Reduction of intracellular oxidative stress may attenuate these pathogenic processes. The dietary polyphenol resveratrol reportedly exerts potential protective effects against endothelial injury. This study determined whether resveratrol can reduce the palmitic acid (PA)-induced generation of reactive oxygen species (ROS) and further explored the underlying molecular mechanisms. We found that resveratrol significantly reduced the PA-induced endothelial ROS levels in human aortic endothelial cells. Resveratrol also induced endothelial cell autophagy, which mediated the effect of resveratrol on ROS reduction. Resveratrol stimulated autophagy via the AMP-activated protein kinase (AMPK)-mTOR pathway. Taken together, these data suggest that resveratrol prevents PA-induced intracellular ROS by autophagy regulation via the AMPK-mTOR pathway. Thus, the induction of autophagy by resveratrol may provide a novel therapeutic candidate for cardioprotection in metabolic syndrome.

Significant increase of assimilable organic carbon (AOC) levels in MBR effluents followed by coagulation

Xiaojie Shi, Zhuo Chen, Yun Lu, Qi Shi, Yinhu Wu, Hong-Ying Hu

《环境科学与工程前沿（英文）》 2021年 第15卷 第4期 doi: 10.1007/s11783-020-1360-8

摘要： Abstract • Annual AOCs in MBR effluents were stable with small increase in warmer seasons. • Significant increase in AOC levels of tertiary effluents were observed. • Coagulation in prior to ozonation can reduce AOC formation in tertiary treatment. • ∆UV254 and SUVA can be surrogates to predict the AOC changes during ozonation. As water reuse development has increased, biological stability issues associated with reclaimed water have gained attention. This study evaluated assimilable organic carbon (AOC) in effluents from a full-scale membrane biological reactor (MBR) plant and found that they were generally stable over one year (125–216 µg/L), with slight increases in warmer seasons. After additional tertiary treatments, the largest increases in absolute and specific AOCs were detected during ozonation, followed by coagulation-ozonation and coagulation. Moreover, UV254 absorbance is known to be an effective surrogate to predict the AOC changes during ozonation. Applying coagulation prior to ozonation of MBR effluents for removal of large molecules was found to reduce the AOC formation compared with ozonation treatment alone. Finally, the results revealed that attention should be paid to seasonal variations in influent and organic fraction changes during treatment to enable sustainable water reuse.
