Background： Atopic dermatitis （AD） is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczemaJAD and to propose Chinese diagnostic criteria for adult/adolescent AD. Methods： A hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients （12 years and over） with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and-investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software. Results： A total of 2662 valid questionnaires were collected （1369 male and 1293 female）. Of all 2662 patients, 2062 （77.5%） patients had the disease after 12 years old, while only 600 （22.5%） patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine （80.4%） patients had the disease for more than 6 months. One thousand one hundred and forty-four （43.0%） patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight （58.2%） patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients. Conclusion： Late-onset of eczema or AD is co

Fe_(0.8)CoSe_(2) nanosphere coated by N-doped carbon for ultra- high rate potassium selenium battery

Rare Metals 2021年第9期40卷 2455-2463页

Potassium-selenium(K-Se) batteries are a promising electrical energy storage candidate because of the cost-effectiveness and material sustainability, yet they suffer from shuttle effect, volume expansion and low powder density. The development of Se-based cathode is an effective way to overcome the above issues. Here we designed a hollow nano-spherical Co-Fe bi-metallic selenide coated with N-doped carbon(denoted as CFS@N-C)as cathode for K-Se batteries. Bimetallic selenide is benefit to improve the conductivity of composite materials;N-doped carbon layer encapsulation effectively inhibits the dissolution of poly-selenides and relieves the volume expansion. The as-prepared K-Se battery exhibits excellent rate performance(300 mAh·g^(-1) at 1000 mA·g^(-1)) and slowcharge/ultrafast-dischargecapability(dischargeat5000 mA·g^(-1) and charge at 100 mA·g^(-1) with ultrahigh capacity of 227 mAh·g^(-1)) with Coulombic efficiency nearly 100%. In addition, the ex-situ high-resolution transmission electron microscopy(HRTEM) images reveal that the charge–discharge mechanism of CFS@N-C is K^(+) replaces the bimetal and forms K_(2)Se. The unique design in this work may provide certain directions on researching for high power density K-storage materials.

Study of damage to a high concrete dam subjected to underwater shock waves

引用

Earthquake Engineering and Engineering Vibration 2014年第2期13卷 337-346页

作者： lu lu Li xin Zhou Jing Faculty of Architecture and Civil Engineering Huaiyin Institute of Technology The State Key Laboratory of Coastal and Offshore Engineering Dalian University of Technology

To study the effect of a strong underwater shock wave on a concrete dam, this research aims to improve hammer impact methods in model tests. Six 1:200 scale models were designed and tested under distributed impact loads. A device was deployed for a direct measurement of the impact force at the upstream face of the dams. The model dam bases were anchored to prevent displacement. The experimental results indicate that the top part of the concrete dam is a weak zone, and the impact failure initiates with a fracture on the top of the dam. The peak value of impact stress increases when the second crack appears in the concrete dam from the upstream face to the downstream face. And, the level of the second crack in the dam body is lower as the peak value of impact stress increases. In this study, dynamic analysis was conducted by calculating the results to verify the effectiveness of a device to directly measure the impact force. This method may be used to approximately forecast the damage of concrete dam and may also be useful in other engineering applications.
