Objective: To ascertain the influence of light intensity and water content of medium on the total dendrobine of Dendrobium nobile(D. nobile).Method: The principal component analysis combined with total dendrobine accumulation was conducted to assess the yield and quality of D. nobile in all treatments. In the experiment, D. nobile plants were cultivated in greenhouse as tested materials, and complete test of 9 treatments was adopted with relative light intensities 75.02%, 39.74%,29.93% and relative water content of medium 50%, 65%, 80%. The plants were treated in June and harvested till December. Indexes including agronomic traits, fresh weight and dry weight of stem and leaf, ash content, extract, and dendrobine were ***: Under the light intensity treatments of 75.02% with 50%, 65%, 80% water content of medium, the basal stems of plants were comparatively thicker with more leaves, and the fresh weight and dry weight of stems and leaves were significantly higher than other 6 *** in all treatments contained dendrobine. Under the light intensity treatments of 75.02%with 50%, 65%, 80% water content of medium, dendrobine content of leaves was lower while dendrobine contents of other treatments were more than 0.60%. After comprehensive assessment through the principal component analysis and total dendrobine accumulation, the results showed that 3 treatments with relative light intensity of 75.02% ranked the top ***: In brief, the moderately strong light intensity and water content of medium from low to medium can facilitate the growth and yield of D. nobile plants, while light intensity from moderately weak to weak can enhance the dendrobine content.

Percutaneous kyphon balloon kyphoplasty has achieved encouraging results in the treatment ofosteoporotic compression fractures, both for correcting spinal deformities and relieving pain. Although kyphoplasty is a small invasion, the surgery itself has some defects such as more X-ray fluoroscopy time during the operation and accumulation of radiation dose causing harm to patients and operators, and the puncture is hard to achieve in a highly precise location.

Journal of Traffic and Transportation Engineering(English Edition) 2024年

Elevated pavement temperatures contribute to the urban heat island effect and pose a risk of thermal damage to pavement. Thus， regulating pavement temperature is paramount to ensure its longevity， enhance traffic safety， and preserve the environment. Phase change materials (PCMs) with the latent heat characteristic can store and release thermal energy via phase transitions. PCMs can effectively control pavement structure temperatures within a relatively narrow range， mitigating thermal stress on asphalt pavements. This research aims to explore the current status and emerging trends in PCM Integrated Pavement Engineering (PCMIPE) using the CiteSpace visual analysis tool. Relevant publications were systematically curated from the Web of Science core database， spanning 2011 to 2023. Subsequently， the co-authorships network maps (country， institution， author)， co-cited network maps (co-cited journals， authors， and references)， and keyword co-occurrence network maps were constructed to analyze the principal contributions in the PCMIPE field comprehensively. This analysis provides an understanding of the field's strengths， research domains， and knowledge structure and identifies current research focal points and emerging frontiers. The findings reveal that research within the PCMIPE field is still in its early stages， with a predominant emphasis on material design and performance assessment. Additionally， future research is anticipated to expand into economic analyses and exploration of environmental effects when integrating PCMs into pavement engineering. Furthermore， there is an emerging interest in investigating the synergy of PCMs with other functional pavement technologies. These results underscore the potential of the PCMIPE field and emphasize the importance of future research endeavors.

Thermal crown of roll is an important factor, which affects strip profile. It is necessary to analyze the temperature field and thermal crown of roll for hot strip mill. A new simplified finite element method （FEM） was used to analyze the temperature field and thermal crown of roll, and corresponding models were built according to the practical boundary conditions. Transient roll temperature field and thermal crown were simulated by ANSYS FEM software with considering transient thermal contact and complex boundary condition. Temperature and thermal crown variations on roll surface nodes were obtained. The thermal crown results of roll obtained by FEM simulation were in good agreement with the measured data, indicating that simplified FEM models and results were correct.
