Constant curvature solutions of Grassmannian sigma models: (1) Holomorphic solutions

We present a general formula for the Gaussian curvature of curved holomorphic 2-spheres in Grassmannian manifolds G(m, n). We then show how to construct such solutions with constant curvature. We also make some relevant conjectures for the admissible constant curvatures in G(m, n) and give some explicit expressions, in particular, for G(2, 4) and G(2, 5).Comment: 14 page

An analysis and evaluation on the nutritional status of senile patients with CAPD after the intervention of effective nursing

目的  对老年CAPD患者进行有效护理干预后对其营养状况进行分析及评估。方法  选择2012年7月—2013年7月老年CAPD患者36例（年龄60～77岁，平均68.5岁）。进行相关的护理干预后分别于干预前，干预3个月，干预6个月进行微型营养评估。结果  36例老年CAPD患者在有效护理干预后其营养状况得到明显的改善及提高（ ＝8.40, P＝ 0.003）。结论  系统、完善的护理干预方案可以很好的提高及改善老年CAPD患者的营养状况。Purpose: To analyze and evaluate the nutritional status of senile patients with CAPD after the intervention of effective nursing. Methods: 36 senile patients with CAPD were enrolled between July 2012 to July 2013 (age from 60~77 yrs, mean age 68.5 yrs). The mini nutritional status was evaluated before intervention, 3 months and 6 months after intervention. Result: the nutritional status of 36 senile patients with CAPD was significantly improved after intervention ( ＝8.40, P＝0.003). Conclusion: Systemic and overall nursing intervention can effectively improve the nutritional status of senile patients with CAPD
