Sir Henry Sumner Maine et les systemes juridiques traditionnels

The birth of comparative law in England is strongly linked with the Ancient Law, its Connection with the Early History of Society and its Relation to Modern Ideas, of Sir Henry Sumner Maine published in 1861. Maine is the first in England to be endowed ‘ad personam’ with the Chair of Comparative Law in Oxford in order to teach legal history and comparative (foreign) law. It is undoubtedly the Roman law that stood in the focus of interest of Sir Henry Sumner Maine serving as basis to carry out comparative legal studies. That approach is in particular manifested in Ancient Law as Maine attributes significance to the various institutions of Roman law. The author draws in particular a comparison between Maine and Bachofen as far as their approach relating to the basis of foreign law related research is concerned. The role that Roman law (ius Romanum), i.e. Civil law (ius civile), played in the development of English law during the centuries is also underlined in this paper, and in its last part, the author emphasizes the contemporary significance of Ancient Law and traditional legal systems for the foreign law related research on the basis of the works of Maine.

Analysis of technical advantages and disadvantages of percutaneous endoscopic lumbar interbody fusion and its trend prospect

To review and evaluate the technical advantages and disadvantages and research progress of percutaneous endoscopic lumbar interbody fusion. The domestic and foreign related research literature on percutaneous endoscopic lumbar interbody fusion was extensively consulted. The advantages, disadvantages, and effectiveness were summarized. And the development trend of this technology was prospected. Compared with minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), percutaneous endoscopic lumbar interbody fusion has less intraoperative and postoperative bleeding, better improvement of low back pain in the early stage after operation, and similar long-term effectiveness, fusion rate, and incidence of complication, but a longer learning curve. The operation time of biportal and large-channel uniportal endoscopic lumbar fusion is close to that of MIS-TLIF, but the operation time of small-channel uniportal endoscopic fusion is longer than that of MIS-TLIF. Percutaneous endoscopic lumbar interbody fusion has the advantages of less trauma and good effectiveness, but its learning curve is long, and indications should be strictly selected for this operation. In the future, with the continuous development and complementation of various endoscopic fusion technologies, this technology will gain better application prospects.

Research progress of traumatic heterotopic ossification

To review and evaluate the research progress of traumatic heterotopic ossification (HO). The domestic and foreign related research literature on traumatic HO was widely consulted, and its etiology, pathogenesis, pathological progress, diagnosis, prevention, and treatment were summarized. Traumatic HO is often caused by severe trauma such as joint operation, explosion injury, nerve injury, and burn. At present, it is widely believed that the occurrence of traumatic HO is closely related to inflammation and hypoxia. Oral non-steroidal anti-inflammatory drugs and surgery are the main methods to prevent and treat traumatic HO. Nowadays, the pathogenesis of traumatic HO is still unclear, the efficiency of relevant prevention and treatment measures is low, and there is a lack of specific treatment method. In the future, it is necessary to further study the pathogenesis of traumatic HO and find specific prevention and treatment targets.

Robot-assisted joint arthroplasty-An emerging technology of the present and the future

To review and evaluate the research progress of the robot-assisted joint arthroplasty. The domestic and foreign related research literature on robot-assisted joint arthroplasty was extensively consulted. The advantages, disadvantages, effectiveness, and future prospects were mainly reviewed and summarized. The widely recognized advantages of robot-assisted joint arthroplasty are digital and intelligent preoperative planning, accurate intraoperative prosthesis implantation, and quantitative soft tissue balance, as well as good postoperative imaging prosthesis position and alignment. However, the advantages of effectiveness are still controversial. The main disadvantages of robot-assisted joint arthroplasty are the high price of the robot system, the prolonged operation time, and the increased radioactive damage of the imaging-dependent system. Compared to traditional arthroplasty, robot-assisted joint arthroplasty can improve the accuracy of the prosthesis position and assist in the quantitative assessment of soft tissue tension, and the repeatability rate is high. In the future, further research is needed to evaluate the clinical function and survival rate of the prosthesis, as well as to optimize the robot system.

Construction methods of urban ecological corridor for birds: A review

The ecological corridors considering bird movement characteristics and habitat requirements would mitigate species extinction caused by habitat loss or habitat fragmentation and facilitate species gene dispersal and exchange. These functions may in turn benefit urban residents' physical and mental health as well as appreciation of real estates. Nonetheless, main ecological corridor construction methods developed by foreign scholars have not internally considered the movement and habitat characteristics of birds, while corridor research for birds by domestic scholars have focused on explorations of foreign technical methods yet lacked enough knowledge on studied birds' characteristics. Therefore, there is still much room for improvement in the study of urban ecological corridor construction from the perspective of birds. Based on the analyses of domestic and foreign related research from 1975 to 2020, we identified seven corridor construction methods and three corridor optimization methods within which bird ecology can be integrated. The advantages, drawbacks, and applicable scenarios of all the methods were explored accordingly. Finally, we argued that the develop-ment of computational models, which could not only combine bird species' observation data and spatial movement data with landscape structures but could also possess efficient computation power as well as simulate corridor's ecological benefits, would be a trend for constructing ecological corridor for birds.

Research progress of different surgical approaches in treatment of acetabular both-column fractures

To review the research progress of different surgical approaches in the treatment of acetabular both-column fractures. The domestic and foreign related research literature on surgical approaches for acetabular both-column fractures was extensively consulted. The anatomical characteristics, exposure ranges, advantages, disadvantages, and indications of various common surgical approaches for both-column fractures were mainly summarized. The ilioinguinal approach is more suitable for both-column fractures if the anterior column fracture is complicated or combined with the anterior wall fracture while the posterior column fracture is simple and stable. The modified Stoppa approach or the lateral (para) rectus abdominal approach is the preferred choice when both-column fractures are combined with a quadrilateral fracture or femoral head dislocation. What's more, the Kocher-Langenbeck approach is required when the posterior column fractures are complicated or combined with posterior wall fractures. In addition, the simultaneous ilioinguinal and Kocher-Langenbeck approaches are the first choices when the both-column fractures possessing extremely severe and obvious displacement. The reasonable choice of surgical approach is extremely important for acetabular both-column fractures. Each surgical approach has its advantages and limitations. It is necessary to take the precise reposition of the acetabular joint surface as the principle, and comprehensively judge the fracture types and severity of anterior column, posterior column, and square area, and then select the optimal surgical approach for surgical treatment.

Analysis on Water Quality Characteristics of Typical Black and Stinking River in Chengdu City by SWMM

In this paper, based on Storm Water Management Model (SWMM) mechanism, referring to the model parameters of domestic and foreign related research achievements, combined with field monitoring data, a non-point source pollution load calculation model is constructed, and the corresponding parameters are calibrated. The pollution load and pollution change process of chemical oxygen demand (CODCr), ammonia nitrogen (NH3-N) and total phosphorus (TP) under different rainfall conditions were analyzed in the investigation area. The model calculated values are in good agreement with the actual measure results. Under different rainfall conditions, the maximum value of pollutants appeared in early and middle rainfall stage, while gradually decreased in latter, with the increase of rainfall, pollution of receiving water becomes greater, and the pollutant concentration shows a downward trend during rainfall process. Measured value of CODCr is higher than the simulated one, both decreased gradually with the rainfall, measured NH3-N concentration in mid-term rainfall increased slightly due to the uninterrupted direct emission of domestic sewage in this area, measured TP concentration in early stage of rainfall declined not obvious, but with the rainfall enhancement, various phosphorus compounds by erosion gradually dissolved finally into the river, partially offset by a dilution effect, as the subsequent rainfall carried over, total phosphorus pollutants continued to decline. While as impervious surface area goes on, both runoff and total pollutants increase.
