Environmental DNA(eDNA)has been used as an important tool for fish diversity analysis,which can greatly solve the problems in traditional survey methodology.However,little work has been done on the actual monitoring accuracy of eDNA.In this study,we analyzed the current status of fish resources in Erhai Lake in Yunnan,SW China,by dividing the lake into three sectors according to habitat differences,and compared the results of eDNA and traditional capture methods to investigate the shortcomings of the current analysis of eDNA results.A total of 27 fish species were detected by eDNA and traditional capture methods,including 20 and 19 fish species,respectively,and additional differences in fish composition between the two methods.The alpha diversity showed higher fish abundance and lower fish diversity by eDNA method compared to the traditional capture method,demonstrating that eDNA was not superior for use in fish diversity analysis.Fish community similarity analysis showed that community differences were generally significant for eDNA(P<0.05).RDA analysis indicated that environmental factors did not significantly affect fish communities monitored by the eDNA method.However,water temperature,aquatic plants,and water depth had significant(P<0.05)effects on fish communities in the traditional capture method,suggesting that eDNA results are insensitive to the effects of environmental factors.Our results illustrate the effectiveness of eDNA in fish identification and the issues in quantification compared to traditional capture methods.Therefore,combining eDNA with traditional methods is a more effective method for analyzing eDNA metabarcoding,following which the protocols of both quantitative methods can be designed to explore the regularity of eDNA quantification. 展开更多

A study on the evaluation of the effectiveness of three traditional methods of protecting guinea fowl from mortality was carried out at CRA-SS (Centre de Recherche Agronomique de la Savane S6che) in northem Togo. Guinea fowl were divided into 5 batches, of which 3 batches received prophylactic medical treatment including plant decoctions, the 4th batch was followed by a medical prophylaxis program as a control group and the 5th batch considered as a negative control, has not received any prophylactic treatment. The results showed that a mortality rate of 25% for the reference lot and two other batches which received plant decoctions (Euphorbia poissonii or Khaya senegalensis) were recorded against a rate of 87.5% in the batch of guinea fowl which received the decoction of Pteleopsis suberosa. Meanwhile, regardless of weight growth, daily average gain (GMQ) or food consumption, no significant difference was observed (p 〉 0.05) between the guinea fowl that received a baseline health monitoring and those having taken the decoction orE. poissonii. On the other hand, the values recorded in these two batches of guinea fowl differed statistically from those in the guinea fowl that received the decoction of K. senegalensis. Although the decoction of K. senegalensis has a protective effect in guinea fowl, the growth of guinea fowl has been slowed down. On the basis of these results, it appears that two endogenous practices tested (K. senegalensis or E. poissonii) have positive effects. However, it would be desirable to carry out a toxicity test in order to determine the recommended doses. 展开更多

Accurate project progress measurement is critical for effective project management. Besides guarantying smooth work progress, it affords project managers the chance to identify early warning signs for peremptory remedial actions to keep the project on schedule and to budget. However, pertinent barriers can suppress the realization of the benefits of an accurate assessment of construction progress. This study aims to identify, examine and prioritize the critical barriers militating against accurate project progress measurement in the Ghanaian construction industry. Sixteen barriers identified from the literature were administered in a questionnaire survey to professionals with tier one construction firms and consultants. Sixty experienced construction professionals practising with tier-one construction firms and consultancy services took part in the survey. The relative importance index technique was used to rank the factors and correlation in responses of the two parties tested by the Mann-Whitney <em>U</em> statistics. The most critical barriers perceived by the professionals were 1) Reliance on Supervisor’s Judgement, 2) Generic and Non-Systematic Approach, 3) Variable Quality of Data and 4) Intricate Measurement Reports. Other highly ranked barriers include 5) Lack of Timely Information, 6) Laborious Data Gathering and 7) Quality Integration Constraint. The findings underpin the need to minimize dependence on subjective opinions and mere experiences of supervisors for assessment of project progress in this age of information technology. Incorporation of a level of automation into traditional progress methods will not only reduce human errors introduced into manually collected data but facilitate visualization of progress reports. Contiguous to a clear specification of the method of progress measurement in the contract document, a system that conveniently integrates cost, time and scope of work into progress measurement must be pursued. Addressing these identified critical barriers will consolidate current construction progress management practices. 展开更多

Amplification effects of soil site response can significantly impact ground motions, and must be considered in the seismic fortification of buildings/structures to prevent or mitigate this potential seismic hazard. Utilizing acceleration time histories from the main shock of the Wenchuan earthquake recorded at four stations (i.e., one on bedrock and three on soil) in the Qionghai Basin, the site responses from three soil sites are studied by using the traditional spectral ratio method. The bedrock site is selected as a reference site. This study found that peak ground accelerations (PGAs) on the soil sites are much larger than on bedrock, with EW, NS and UD components of 3.96-6.58, 6.27-10.98, and 3.17-6.66 times those of the bedrock site, respectively. The amplification effects of the soil sites on ground motions in the frequency range of 0.1 Hz to 10 Hz are significant, depending on the thickness of the soil layer and the frequency content of the site. A significant amplification occurs with high frequency components of ground motion at shallow soil sites, and low and high frequency components of ground motion at intermediate soil sites. 展开更多

To observe the clinical effect of treatment of acute bronchitis primarily with prickingcupping method on Back-shu points. Methods. The patients of acute bronchitis were randomly divided into 2 groups. In the observation group, there were 36 cases, who were treated with the integrated traditional Chinese and western medicine, primarily the pricking-cupping method on Back-shu points; while in the control group, there were 29 cases who were given the conventinal treatment of western medicine. All the 2 groups were treated for 7 days as one treating course. Results: The total effective rate of the observation group was 97.2% while that of the control group was 82,8%, so there is a significant difference between them. On the first and third days the clinical manifestations were more satisfactorily improved in the treatment group than in the control group (P 〈 0.01) and on the fifth and seventh days, the comparison showed no significant difference (P〉0.05). Conclusion: The treatment of acute bronchitis by means of the integrated traditional Chinese and western medicine primarily with pricking-cupping method on Back-shu points is of marked therapeutic effect, simple manipulation, and little untoward effects, thus claiming the unique advantage. 展开更多

Predicting the failure time of unstable slopes is one of the most pivotal issues. In this paper, the inverse square root acceleration(INSRA) method was proposed to estimate the time-of-failure(TOF) of landslides. Four collapsed slopes were presented in the three open-pit mines, two of them were probed by ground-based radar, and two of them were obtained from previous scientific papers. The inverse velocity(INV) method and INSRA method were adopted to analyze these four landslides and one slope which had great deformation but did not reach failure. Compared with the traditional INV method, the INSRA method can promote the forecasting effectiveness and has the advantage of higher accuracy. 展开更多

OBJECTIVE: To evaluate the effect of Huadananshen mistura in clinical treatment of Chinese patients with insomnia. METHODS: In this randomized, double-blind, placebo-controlled, multi-center study, 244 patients with insomnia were randomly assigned to a placebo group, a low-dose (10 mL/day), or a high-dose (20 mL/day) mistura group. Efficacy was assessed by using the sleep dysfunction rating scale (SDRS) and Clinical Global Impression-Improvement (CGI-I) scores. Safety and tolerability assessments included emergent adverse events, laboratory tests, and electrocardiograms. RESULTS: Total SDRS scores decreased in all three groups, and there were significant differences between the placebo group and the lowand high-dose mistura groups (P=0.000). CGI-I ratings in the lowand high-dose mistura groups were sig-nificantly better than that of the placebo group (P= 0.000). Incidences of rebound insomnia were similar in all three groups (placebo group: 6.94% , low-dose mistura group: 12.99% , and high-dose mistura group: 10.96% ; P=0.475). The efficacy of Huadananshen mistura in the lowor high-dose group was significantly better than that of the placebo group (P=0.000), but with no significant difference found between the lowand high-dose mistura groups (P=0.887). The rates of adverse events were similar in the three groups (placebo 2.44% , low-dose mistura 0%, and high-dose mistura 5%; P=0.088). CONCLUSION: Huadananshen mistura is an effective and generally well-tolerated hypnotic medicine for the treatment of Chinese patients with insomnia. 展开更多
