为了探究钢管再生混凝土混合柱框架的抗震性能,设计4榀圆钢管再生混凝土混合柱框架并对其进行低周往复荷载试验,以混凝土取代率、柱截面含钢率为参数变量得到混合柱框架的梁端、柱脚及核心区的应变分布规律、滞回曲线和骨架曲线。结果表明,4榀混合柱框架的滞回曲线均饱满呈梭形,说明框架延性性能较好;骨架曲线在进入弹塑性阶段后更平缓,说明框架的耗能能力和抗震性能均较好;梁端塑性铰位置出现在30～90mm范围内,柱脚塑性铰位置出现在40～100mm范围内,说明梁端及柱脚的高应力区存在于这两个位置,设计时应考虑在此薄弱区进行加强。根据钢管再生混凝土混合柱框架在低周往复荷载作用下的滞回规则,得到荷载-位移滞回曲线恢复力模型。将模型计算与试验结果得出的关系曲线进行对比,得出两种滞回曲线差距控制在4%～7%范围内,验证了分析模型的准确性。

Genetic counseling has the characteristics of professionalism, precision, ethics and the rule of law. The legal risks of genetic counseling include unqualified genetic counselors, disclosure of personal genetic information, endangering biosafety, genetic discrimination, violation of patients’rights to informed consent and family members’rights to lives and health. The article suggests refining genetic counseling in China, including improving the qualification certification of genetic counselors, the regulations on the protection of personal genetic information, the regulations on avoiding biosafety risks, the regulations against gene discrimination, the regulation of the right to informed consent and right to life and right to health.

Paper mulberry (Broussonetia papyrifera) with high crude protein, biological yield and rich nutrients, was widely planted in China, and contains a variety of biologically active ingredients. Paper mulberry can improve the immunity and quality of livestock and poultry. Also, paper mulberry has been widely used in animal production and was listed in the feed catalogue of agricultural feed materials by the Ministry of Agriculture and Rural Affairs. The article reviews the nutritional value, processing methods, feeding techniques and feeding effects of paper mulberry in animal production, and provide a reference for promoting the feed utilization of paper mulberry.

Objective To analyze the characteristics, treatment process and therapeutic effect of Madelung's disease and to explore the diagnosis and treatment of this disease. Methods The clinical data of 12 patients with Madelung's disease from February 2014 to April 2019 were collected. The clinical diagnosis, treatment process and results were retrospectively analyzed. Results All incisions in 12 patients were healed well and no infection or hematoma was occurred. All patients were followed-up from 5 to 64 months, with an average of 37.8 months. The recurrence rate was 41.7U (5/12). Local recurrence at original incision was occurred in 3 patients and at other sites was occurred in 2 patients. Conclusion The diagnosis of Madelung's disease should be based on clinical manifestations, radiographic assessment and pathological examination. Surgery was the main treatment method at present. However, the overall recurrence rate was high. Individualized treatment and close follow-up were needed. [ABSTRACT FROM AUTHOR]
