This paper, by means of quantitative and qualitative analysis based on a vast investigation, talks about the anomie in China's academic publishing from the following three aspects: first, disorders in format; second, misspellings & improper expressions of English language; third, misconduct in ethics. It introduces renovation measures taken by the country's related authorities and practitioners and probes into the deep-seated reasons why so little effect has so far been achieved. It's the first time that scholars have ever reviewed disorders in China's academic publishing in such a multi-dimensional scope. Through briefing the raft of reforms currently launched by the Chinese Communist Party and the State Council, the author expresses her expectation on the upturn of the situation.

This paper establishes a mathematical model for analyzing and predicting China's water resources. It first makes a macro-level early warning forecast for water storage across the country. The forecast adopts the revised forecast and linear forecast methods considering different weights. The macro warning of China's water supply and demand shows that the forecast result is in accordance with China's existing forecasts, and the error is less than 5%. The coupling model based on the Particle Swarm Optimization is adopted in the optimization of the water transfer plan, and the optimal plan for the regulation and control project is obtained through multiple iterations in the D-dimensional space at the micro level. The optimal plan for the social and ecological environment and the fuzzy optimal model are used to demonstrate the optimal plan. This paper further discusses the negative impacts of various beneficial projects on the environment and water conservation. [ABSTRACT FROM AUTHOR]

The novel coronavirus has had a huge impact on the world, not only for those infected, but for the population at large in the context of the work, money incoming, economy. In this paper, our objective is to study different types of tweets collected from Twitter from different perspectives of analysis, and machine learning classification. Previous work extracted a large corpus of tweets based on keywords such as [الصین ، تفشي ، السفر ، كورونا,[which translate to China, Corona, outbreak, travel; however, we hypothesis that not all these are genuinely relevant to Covid-19. In this work, we combine different machine learning models to classify tweets into those that do discuss the Coronavirus and those that do not. In our result, based on the different analysis and models, we have seen that more than 55% of these tweets were talking about topics other than the Coronavirus. These indicates the care that must be taken when extracting tweets, particularly in a language like Arabic, which has many nuances that make simple keyword approaches prone to error.

Based on a nationwide investigation of the current state of preservation of museum objects in China, around 51% of the 35 million museum objects show different degrees of deterioration. Although treatment of objects is necessary, treatment alone is not sufficient. In China's present situation, preventing damage to museum objects is much more cost-effective than allowing damage to happen and then treating it. The number of museums in China is increasing very fast: 23 000 exhibitions are held, 600 million visits are made, and 35 000 archaeological objects are excavated nationwide, each year. At the same time, these museums are widely distributed and have different levels of resources. We need both technical knowledge and preventive conservation to safeguard our precious museum objects. This paper introduces research achievements in preventive conservation, and traces the development of this discipline in China. Starting from the classification of museums in China, legislation is detailed on preventive measures such as selecting appropriate light sources, controlling temperature, relative humidity, light damage, and pollutants. This paper describes achievements in monitoring, analysis, evaluation, and control of museum environments in China. It also proposes future directions for museum environment studies during China's twelfth Five-Year Plan. [ABSTRACT FROM AUTHOR]

Calculating wind resistance is an important process in the design of highway bridges. The current codes of many countries include different rules and formulas regarding the calculation of wind resistance. In this paper, the transverse-direction wind loads on long-span girder bridges with tall piers were calculated using six codes from different countries under various terrain, pier height, and girder length conditions. The pier-bottom shear force and moment results of transverse wind loads calculated using these six codes were compared with those obtained using the buffeting frequency domain method. Results showed that, in Class B terrain, wind load results predicated on China's 2004 general codes for the design of highway bridges and culverts, China's 2004 wind-resistant design specifications for highway bridges, Japan's 2007 wind-resistant design manual for highway bridges, and Part 2 of Britain's 2006 steel, concrete, and composite bridge specifications for loads resembled each other closely. Some difference was found to exist among Classes A, C, and D terrain. The 2007 AASHTO LRFD bridge design specifications and China's 2001 load codes for the design of building structures showed significant differences from the other four codes on all kinds of terrain. The applicability of the wind load rules in the AASHTO LRFD bridge design specifications to long-span girder bridges with tall piers merits further discussion. China's wind load calculations of load code for the design of building structures mainly depended on the empirical parameters of architectural structures with large dimensions, and had limited applicability to bridge structures. For long-span girder bridges with tall piers, such as bridges with span length-to-width or -depth ratios exceeding 30, or pier height-to-transverse-width ratio exceeding 10.7, the wind load calculated using these codes was generally underestimated due to the neglect of the effects of aeroelastic forces, which must be taken into account in the design of these kinds of bridges.

Pedestrian-car interweaving is a prominent problem in old residential communities in Chinese cities. To achieve a better pedestrian-car separation to create a safe and comfortable living environment in old residential communities, this paper investigated the mechanism of the flows of pedestrians and cars on a road network inside an old residential community. A method for calculating the flows of pedestrians and cars was proposed to identify the road segments or nodes where the pedestrian flows are interlaced or intersected with the vehicle flows. This method was applied to the estimation of the traffic in the Wangyuehu Community of Changsha City, China. The estimated distribution of community network traffic and pedestrian-car interweaving sites was consistent with the actual situation. [ABSTRACT FROM AUTHOR]

The Second Integrated Research on Disaster Risk Conference was held in Beijing, China, on the 7th to 9th of June, 2014. This event gathered a diverse international combination of researchers, policy makers, practitioners, funders and disaster risk reduction agencies, to discuss the applied integration of disaster risk research. The current special issue consists of papers with an explicitly social focus which were presented at this conference. These papers are discussed in terms of vital elements for integrated disaster risk science, namely: analysis, theory and links to practice. The special issue papers include a landmark case study of community-led disaster recovery, amongst indigenous Māori affected by the earthquakes of 2011 and 2012 in Canterbury, New Zealand. Another paper takes an international approach, to analysing the use of the term 'disaster' in English speaking contexts. A paper on vulnerability and response to disasters provides a detailed account of needs for disaster risk reduction in low-income countries, such as Ghana. Vulnerabilities are also explored in a paper about the challenges faced by people with disabilities during an earthquake. The special issue concludes with a thought-provoking paper on concepts of modernity, which takes an expansive and historical view of the disaster risk domain. In sum, special issue authors have produced relatively unique combinations of disaster risk analysis, theory and links to practice. This special issue therefore represents an important illustration of integrated disaster risk research. [ABSTRACT FROM AUTHOR]

Abstract: This paper first defines the term “urban fire risk” by referring to both the definition of “risk” in U.N.’s “International Strategy for Disaster Reduction” which was enacted in 2004 and the features of urban fire. Secondly, this paper presents a comprehensive analysis on the urban fire risk from the respects of risk of fire accidents in urban areas, urban vulnerability and urban anti-fire capability. Based on the analysis, the Analytic Hierarchy Process (AHP) is employed in this paper to establish an urban fire risk assessment system, which includes 3 first-level indicators, 13 second-level indicators and 48 third-level indicators. With the data on fire accidents and fire statistics in the past as the basis, this paper applies the Gray Correlation Degree Method to set up the Weight Coefficient of the system and quantify the indicators mentioned above, and finally, this paper applies what has been discussed above to the case of Haikou, capital city of Hainan province, P.R. China. In the city''s chosen 17 sub-districts and 1 town, fire risk assessments are conducted, and the values of risk of fire accidents in urban areas, urban vulnerability, anti-fire capability and comprehensive fire risk in the mentioned selected areas are computed and identified.

The karst groundwater system is extremely vulnerable and easily contaminated by human activities. To understand the spatial distribution of contaminants in the groundwater of karst urban areas and contributors to the contamination, this paper employs the spatial information statistics analysis theory and method to analyze the karst groundwater environment in Guiyang City. Based on the karst groundwater quality data detected in 61 detection points of the research area in the last three years, we made Kriging evaluation isoline map with some ions in the karst groundwater, such as SO, Fe, Mn and F, analyzed and evaluated the spatial distribution, extension and variation of four types of ions on the basis of this isoline map. The results of the analysis show that the anomaly areas of SO, Fe, Mn, F and other ions are mainly located in Baba'ao, Mawangmiao and Sanqiao in northwestern Guiyang City as well as in its downtown area by reasons of the original non-point source pollution and the contamination caused by human activities (industrial and domestic pollution).

It is well recognised that a significant amount of solid waste is produced from construction work. The increasing generation of construction waste such as used timber formwork, obsolete concrete and packaging, has caused significant pollution to the environment and risen public concern particularly in densely populated cities, such as Hong Kong. The minimization of construction waste has therefore become a pressing issue in pursuing the practice of sustainable construction. This paper shows the betterment of replacing in situ concreting with precast slabs for temporary works to improve sustainable construction performance. Construction waste from the obsolete concrete constitutes a large part of the construction solid waste in a typical building project. The reduction on the obsolescence by using precast slabs can significantly contribute to improving sustainable construction performance. This study identifies cost saving and the betterment of environmental performance by using precast concrete slabs over the in situ concreting. The data used for analysis in the paper were collected from statistics reports and a case study in Hong Kong construction practice. From the case study results, about 43.93%, 64.01% and 70.70% of the cost of using cast in situ concreting can be saved by reusing precast slabs once for temporary works, twice and three times respectively. The findings provide evidence for promoting the use of precast slabs for temporary works, and contribute to the improvement of sustainable construction performance. [Copyright &y& Elsevier]

To gain an understanding of the outbreaks of bacterial foodborne diseases and the subsequent health impact, we reviewed 2447 papers from journals published in China that reported 1082 bacterial foodborne disease cases occurring between 1994 and 2005. Among the 1082 outbreaks of bacterial foodborne disease for which the etiology was determined, Vibrio parahaemolyticus caused the most outbreaks, followed by Salmonella, and Clostridium botulinum led to the most deaths. Most of the outbreaks occurred between May and October, except for Clostridium botulinum, which mainly occurred in January and February. In littoral provinces, Vibrio parahaemolyticus caused the most events, whereas in inland provinces, the largest percentage of events was caused by Salmonella. This review provides a background and analysis of Chinese foodborne disease caused by bacteria. We hope that this review can be compared to reviews from other regions of the world, in an attempt to prevent future outbreaks from occurring. [ABSTRACT FROM AUTHOR]

Background: The purpose of the present paper was to investigate the status of Crohn’s disease hospitalization in China. Methods: Medical records of hospitalized Crohn’s disease came from 22 medical centers across China during 1990–2003 and were retrospectively reviewed. Every incident case was recorded in detail on a regular comprehensive datum form by investigators in person. Clinical manifestations, examinations and therapeutic status were analyzed. Results: A total of 515 cases of Crohn’s disease were found. The ratio of patients with Crohn’s disease to total hospitalized patients has increased steadily year by year. Endoscopy was performed in 348 patients (67.57%). Barium meal or enema was performed in 221 patients (42.91%). Histological examination (endoscopical or surgical biopsy) was performed in 340 patients (66.02%). Reasonable treatment strategies were used for 435 patients (84.47%). The evaluation of quality of life for 54/303 patients (17.82%) was poor. Conclusions: This retrospective, hospital-based study shows that the number of patients with Crohn’s disease in China has steadily increased over a period of 14 years. Further population-based epidemiological studies specifically focusing on risk factors are needed. The diagnosis of Crohn’s disease and therapeutic strategy require improvement.

Background Wendan decoction (WDD) has been used as a treatment for depression in China since the Tang Dynasty. However, high-quality evidence for this is lacking. This study proposed a novel synthetic external control method to evaluate its clinical efficacy. Methods We searched public databases for clinical trials of WDD for major depression. The rate of change of the Hamilton Depression Scale score from baseline was used as an efficacy indicator, and a model-based meta-analysis was performed to analyze the clinical efficacy of WDD. To establish a reference standard for efficacy, the antidepressant efficacy distributions of a placebo and 19 antidepressants were virtually synthesized based on the same conditions as the clinical trial characteristics of WDD. Results This study included 5 clinical trials with 177 participants. WDD showed a slow onset, with a time to reach the maximum effect of 9.71 weeks. At 8 weeks, the rate of change in the Hamilton Depression Scale score from baseline was 66.4% (95% CI = 62.3%–70.3%) in the WDD group. The pure effect value of WDD, after deducting the placebo effect, was 26.9% (95%CI = 23.0%–30.9%), which was comparable with 5 types of antidepressants and significantly higher than the others. Conclusion The proposed external synthetic control method provides a solution to the bottleneck problem of clinical efficacy evaluation in real-world research on traditional Chinese medicine. WDD has high clinical development value for the treatment of depression, and large-scale randomized controlled trials are recommended to confirm its antidepressant effect. [ABSTRACT FROM AUTHOR]

A three-dimensional MOOC analysis framework was developed, focusing on platform design, organizational mechanisms, and course construction. This framework aims to investigate the current situation of big data MOOCs in the intelligent era, particularly from the perspective of improving the mental health of college students; moreover, the framework summarizes the construction experience and areas for improvement. The construction of 525 big data courses on 16 MOOC platforms is compared and analyzed from three aspects: the platform (including platform construction, resource quantity, and resource quality), organizational mechanism (including the course opening unit, teacher team, and learning norms), and course construction (including course objectives, teaching design, course content, teaching organization, implementation, teaching management, and evaluation). Drawing from the successful practices of international big data MOOCs and excellent Chinese big data MOOCs, and considering the requirements of authoritative government documents, such as the no. 8 document (J.G. [2019]), no. 3 document (J.G. [2015]), no. 1 document (J.G. [2022]), as well as the "Educational Information Technology Standard CELTS-22—Online Course Evaluation Standard", recommendations about the platform, organizational mechanism, and course construction are provided for the future development of big data MOOCs in China.

With the development of the economy and industrial construction, air quality deteriorates dramatically in China and seriously threatens people's health. To investigate which factors most affect air quality and provide a useful tool to assist the prediction and early warning of air pollution in urban areas, we applied a sensor that observed air quality big data, information theory-based predictor significance identification, and PEK-based machine learning to air quality index (AQI) analysis and prediction in this paper. We found that the stability of air quality has a high relationship with absolute air quality, and that improvement of air quality can also improve stability. Air quality in southern and western cities is better than that of northern and eastern cities. AQI time series of cities with closer geophysical locations have a closer relationship with others. PM2.5, PM10, and SO2 are the most important impact factors. The machine learning-based prediction is useful for AQI prediction and early warning. This tool could be applied to other city's air quality monitoring and early warning to further verify its effectiveness and robustness. Finally, we suggested the use of a training data sample with better quality and representatives to further improve AQI prediction model performance in future research. [ABSTRACT FROM AUTHOR]

Microplastics (MPs) are ubiquitous in the environment and more abundant in the marine environment. Consequently, increasing focus has been put on MPs in oceans and seas, while little importance has been attached to their presence in freshwaters and soils. Therefore, this paper aimed to provide a comprehensive review of the occurrence, analysis and ecotoxicology of MPs. The abundance and distribution of MPs in several typical freshwater systems of China were summarized. It suggested that the surface water of Poyang Lake contained the highest concentration of 34 items/L MPs among all the 8 freshwater systems, and the content of MPs in sediments were higher than that of the surface water. Net-based zooplankton sampling methods are the most frequently utilized sampling methods for MPs, and density separation, elutriation and digestion are three major pretreatment methods. Fourier transform infrared spectroscopy, Raman spectroscopy and pyrolysis-gas chromatography coupled to mass spectrometry are often used to identify the polymer types of MPs. Besides, MPs might damage the digestive tract of various organisms and negatively inhibit their growth, feeding and reproduction. The ways of human exposure to MPs are by ingestion, inhalation and dermal exposure, digestive and respiratory system might be adversely influenced. However, potential health risks of MPs to humans are remained insufficiently researched. Overall, by showing the presence of MPs in freshwaters and soils as well as possible ecotoxicological effects on the environment and humans, this paper provided a framework for future research in this field. Image 1 • Occurrence and distribution of microplastics in freshwater systems were discussed. • Sampling and analytical methods of microplastics in soils and waters were reviewed. • Ecological effects of microplastics on organisms and humans were summarized. • Research gaps were revealed and future research recommendations were proposed.

China faces a difficult choice of maintaining socioeconomic development and carbon emissions mitigation. Analyzing the decoupling relationship between economic development and carbon emissions and its driving factors from a regional perspective is the key for the Chinese government to achieve the 2030 emission reduction target. This study adopted the logarithmic mean Divisia index (LMDI) method and Tapio index, decomposed the driving forces of the decoupling, and measured the sector's decoupling states from carbon emissions in Xinjiang province, China. The results found that: (1) Xinjiang's carbon emissions increased from 93.34 Mt in 2000 to 468.12 Mt in 2017. Energy-intensive industries were the key body of carbon emissions in Xinjiang. (2) The economic activity effect played the decisive factor to carbon emissions increase, which account for 93.58%, 81.51%, and 58.62% in Xinjiang during 2000–2005, 2005–2010, and 2010–2017, respectively. The energy intensity effect proved the dominant influence for carbon emissions mitigation, which accounted for −22.39% of carbon emissions increase during 2000–2010. (3) Weak decoupling (WD), expansive coupling (EC), expansive negative decoupling (END) and strong negative decoupling (SND) were identified in Xinjiang during 2001 to 2017. Gross domestic product (GDP) per capita elasticity has a major inhibitory effect on the carbon emissions decoupling. Energy intensity elasticity played a major driver to the decoupling in Xinjiang. Most industries have not reached the decoupling state in Xinjiang. Fuel processing, power generation, chemicals, non-ferrous, iron and steel industries mainly shown states of END and EC. On this basis, it is suggested that local governments should adjust the industrial structure, optimize energy consumption structure, and promote energy conservation and emission reduction to tap the potential of carbon emissions mitigation in key sectors.

This study was carried out to explore the moderating effect of comic education and locus of control (LOC) in innovation and entrepreneurship education in colleges and universities. Firstly, the theoretical knowledge of comic education, innovation and entrepreneurship education, and LOC was briefly introduced, and the significance of comics for innovation and entrepreneurship education was discussed. Secondly, the existing innovation and entrepreneurship education modes in colleges and universities in China were introduced. Thirdly, a simple comparative analysis was conducted on the internal and external characteristics of LOC. Finally, an investigation was performed on the innovation and entrepreneurship ability of college students. The results demonstrate that the average score of students' innovation spirit is 3.302, with a standard deviation of 0.481, suggesting that the current college students' overall innovative spirit is moderate. Besides, students get moderate scores in each dimension, and the difference between different students is slight. Among them, the mean of reflectiveness is the highest (M = 3.446, SD = 0.540), and the mean of criticality is the lowest (M = 3.160, SD = 0.481). The average score of the current students' entrepreneurial ability is 3.112, indicating that the students' entrepreneurial ability is above the average. From the perspective of each dimension, students have the lowest score in opportunity discovery ability, which is at a low level (M = 2.821, SD = 0.873), while the other five dimensions are at a medium level. The highest is strategic decision-making ability (M = 3.264, SD = 0.749). At the same time, factors such as gender, grade, institution, and students' relatives significantly impact students' innovation and entrepreneurship ability. It can be concluded that colleges and universities should focus on controlling the quality of innovation and entrepreneurship teaching and guiding and carrying out innovation and entrepreneurship practice activities. They should also encourage students to participate in courses and activities related to innovation and entrepreneurship to improve college students' innovation and entrepreneurship ability.

Tongwamen Bridge is a critical link between Dongmen Island and the land in Shipu town, Zhejiang province, China. It is a 238 m span, half-through, concrete-filled steel tubular (CFST) X-type arch bridge. The width of the deck is only 10 m, yielding a width-to-span ratio of 1/23.8. The plane truss type section rib was adopted, which made of two CFST chords and web member system. The lateral stability is the key issue to this bridge. However, the existing researches on Tongwamen Bridge's lateral stability are all the deterministic structural analysis. In this paper, a new strategy for positioning sampling points of the response surface method (RSM), based on the composite method combining RSM with geometric method for structural reliability analysis, is employed to obtain the reliability index of lateral stability. In addition the correlated parameters were discussed in detail to find the major factors. According to the analysis results, increasing the stiff of lateral braces between the arch ribs and setting the proper inward-incline degree of the arch rib can enhance obviously the reliability of lateral stability. Moreover, the deck action of non-orienting force is less than the two factors above. The calculated results indicate that the arch ribs are safe enough to keep excellent stability, and it provides the foundation that the plane truss rib would be a competitive solution for a long-span, narrow, CFST arch bridge.

Understanding the behavior of the borehole temperature recovery process, which influences drilling operations, requires an adequate estimation of fluid temperature. The presence of salt in a saline formation changes the composition of the annular fluid and has a significant impact on the fluid temperature distribution during drilling operations. As a result, while drilling a saline formation, it is vital to examine the key parameter that determines an accurate estimate of fluid temperature. Using python software and statistical quantitative methods, this study proposes a simplified user-friendly computational system that analyzes the drilling fluid systems performance evaluation and selection optimization. The fluid temperature distribution of X Field in China was analyzed using Shan mathematical model as a base model. When compared to MWD data from the field, the model predicted the temperature distribution of the field with less than 10% error. An adjustment factor was introduced to the base model to accommodate for changes in annular fluid composition while drilling a saline formation. The findings show that salt concentration has an impact on fluid temperature distribution during drilling. The fluid temperature at the wellbore condition changes by at least 7% with both high and low adjustment factors. Because the salt in the formation inflow dissolves in the drilling fluid near the annulus, the rheology of the fluid combination changes. [ABSTRACT FROM AUTHOR]

The service areas of the BeiDou Navigation Satellite System (BDS) are China, the Asia–Pacific, and the world via three stages of development. The BDS constellation is designed to maintain a geostationary Earth orbit (GEO), inclined geosynchronous orbit (IGSO), and medium Earth orbit (MEO). These orbital maneuvers yield certain difficulties for data processing, especially for the BeiDou satellites, such as a decrease in the real-time service performance, which causes a missing precise orbit product from the maneuvered satellites. The frequencies of the orbital maneuvers for the GEO and IGSO satellites are higher than those for the MEO satellites. The maneuvering time and strategy cannot be obtained by common users due to secrecy, which can yield a decline in the service performance of the BDS. Thus, in this study, we analyzed the variation in the orbital semimajor axis for the satellites. The long-term variation in the orbital semimajor axis changes linearly. The short-term variation in the orbital semimajor axis also has periodicity, which can be described by the sum of sine functions. According to the long-term variation in the orbital semimajor axis for the satellites, we propose a detection method for in-plane orbital maneuvering of the GEO, IGSO, and MEO satellites. We then propose a detection method for out-of-plane maneuvering of the GEO satellites. BDS and Global Positioning System (GPS) data from the broadcast ephemeris were analyzed to verify the proposed methods. The experimental results from 2013 to 2019 show that the frequency of orbital maneuvering is approximately once a month for the GEO satellites, once every six months for the IGSO satellites, and once every 1.4 years for the MEO satellites.

Purpose: To explore the feasibility of sacral-2-alar (S2-alar) screw placement by measuring the length, diameter, and angle of the screw trajectory on computed tomography (CT). Methods: This study selected 100 Han-nationality adults in northern China with a normal spine and pelvis. CT data were imported into PHILIPS software for reconstructing the 3D digital images. The optimal S2-alar screw trajectory was imitated on CT. Parameters including the length of the screw trajectory, sagittal angle, coronal angle, distance between the entry point and the spinous process, and minimum diameter of the screw trajectory were measured to evaluate the application of S2-alar screws. Results: In total, 48 males and 52 females were included. The average length of the left screw trajectory was 47.18 ± 3.91 mm. The sagittal angle was 29.06 ± 4.00°. The coronal angle was 13.31 ± 6.95°. The distance between the entry point and the spinous process was 21.0 (3.7) mm. The minimum diameter of the screw trajectory was 17.1 (2.3) mm. The average length of the right screw trajectory was 45.46 ± 4.37 mm. The sagittal angle was 23.33 ± 4.26°. The coronal angle was 14.88 ± 6.84°. The distance between the entry point and the spinous process was 22.8 (2.9) mm. The minimum diameter of the screw trajectory was 16.9 (3.1) mm. In women, the average length of the left screw trajectory was 44.80 ± 3.66 mm. The sagittal angle was 32.14 ± 5.48°. The coronal angle was 16.04 ± 7.74°. The distance between the entry point and the spinous process was 21.8 (2.8) mm. The minimum diameter of the screw trajectory was 17.1 (5) mm. The average length of the right screw trajectory was 44.01 ± 3.72 mm. The sagittal angle was 25.12 ± 5.19. The coronal angle was 16.67 ± 8.34°. The distance between the entry point and the spinous process was 21.6 (2.7) mm. The minimum diameter of the screw trajectory was 17 (4.5) mm. As seen from the data, there were significant differences in the minimum diameter of the screw trajectory in both males and females. In females, there were also significant differences between the left and right sides in the coronal angle. Between males and females, there were statistically significant differences in the length of the screw trajectory. There were no statistically significant differences in the other parameters between males and females. Conclusion: The optimal screw trajectory of the S2-alar screw can be found on CT. The length and deflection angle of the screw meet the clinical requirements. This method is easy to perform and feasible for clinical application. [ABSTRACT FROM AUTHOR]

The analysis of medicinal plants has had a long history, and especially with regard to assessing a plant's quality. The first techniques were organoleptic using the physical senses of taste, smell, and appearance. Then gradually these led on to more advanced instrumental techniques. Though different countries have their own traditional medicines China currently leads the way in terms of the number of publications focused on medicinal plant analysis and number of inclusions in their Pharmacopoeia. The monographs contained within these publications give directions on the type of analysis that should be performed, and for manufacturers, this typically means that they need access to more and more advanced instrumentation. We have seen developments in many areas of analytical analysis and particularly the development of chromatographic and spectroscopic methods and the hyphenation of these techniques. The ability to process data using multivariate analysis software has opened the door to metabolomics giving us greater capacity to understand the many variations of chemical compounds occurring within medicinal plants, allowing us to have greater certainty of not only the quality of the plants and medicines but also of their suitability for clinical research. Refinements in technology have resulted in the ability to analyze and categorize plants effectively and be able to detect contaminants and adulterants occurring at very low levels. However, advances in technology cannot provide us with all the answers we need in order to deliver high-quality herbal medicines and the more traditional techniques of assessing quality remain as important today.

The super larger span tunnel is a common form of highway reconstruction and expansion projects in recent years. In order to determine the stability of tunnel structure of the two-step and three-section excavation method of the III-level surrounding rock mass of the super larger span highway, the field test method was adopted. Relying on the Laohushan Tunnel in Jinan, Shandong, China, the deformation and the structure performance of the super larger span tunnel in III-level surrounding rock mass are analyzed, and the safety of the tunnel and the support structure is evaluated on this basis. The results show that the maximum settlement of the arch section of the Grade III surrounding rock section is 12.5mm, and the maximum clearance convergence is 5.8mm. Both of them are much smaller than the design reserved deformation of 80mm. The maximum pressure of the surrounding rock is 0.091MPa, showing that the force acting on the supporting structure by surrounding rock mass is small. The inner and outer arched parts of the steel frame are subject to large stresses, and most of them are tensile stresses. The maximum stress of the steel frame is 283 MPa, and occurs at the inner side of right arch waist. Although the local stress exceeds the yield strength of the steel (235 MPa), it does not exceed its ultimate compressive strength of 400 MPa, and the tensile and compressive stress values of the other inner and outer parts do not exceed the yield strength. Mainly, the maximum stress appears on the left side wall, reaching 4.83 MPa, which is far less than the ultimate compressive strength of sprayed concrete (11.9 MPa). For super larger span highway tunnels, located in III-level surrounding rock mass, constructed by two-step and three-section excavation method, the initial support effectively controlled the tunnel deformation, the supporting structures were fully protected and the tunnel structure was stable. The super larger span tunnel is a common form in the road reconstruction and expansion project in recent years. In order to determine the stability of tunnel structure of the two steps and three excavation method of the III-level surrounding rock mass of the super larger span highway, the field test method was adopted. Relying on the Laohushan Tunnel, the deformation and the structure performance of the super larger span tunnel in III-level surrounding rock mass were analyzed. The results show that the maximum settlement of arch of the III-level surrounding rock mass is 12.5mm in super larger span highway tunnel, and the maximum clearance convergence is 5.8mm. Both of them are smaller than the design reserved deformation of 80mm. The maximum surrounding rock mass pressure is 0.091MPa, the force acting on the supporting structure by surrounding rock mass are small. The inner and outer arched parts of the steel frame bear larger stress, and are mostly tensile stress. The maximum stress on inner side of the steel frame is 283 MPa, and occurs at the right arch waist. The maximum stress on the outer side of the steel frame is184 MPa, and occurs at the vault. The steel frame plays an important role in the initial support, however the force does not reach the yield strength of the steel. The shotcrete is subjected to pressure, the maximum stress appears on the left side wall is 4.83 MPa, which is much smaller than the ultimate compressive strength of shotcrete of 25 MPa. So for super larger span highway tunnels, located in III-level surrounding rock mass, constructed by two-step and three-excavation method, the whole structure is stable. [ABSTRACT FROM AUTHOR]
