Genetic Relationships among Prunus mume var. pendula Using AFLP Markers

Genetic relationships among Prunus mume var. pendula were studied by using AFLP markers. 18 accessions representing 14 cultivars of Prunus mume var. pendula were selected from the germplasm collection at the Research Center of China Mei Flower. Seven Mse I-EcoR I AFLP primer combinations revealed 450 legible bands, and 269 of which were polymorphic markers. A similarity matrix was prepared using the simple matching coefficient of similarity and Neis (72) distance coefficient. A UPGMA dendrogram demonstrated the genetic relationships of the cultivars. The information given by AFLP markers was basically consistent with the morphological classification and the evolutionary history of the morphotypes, and roughly supported the new revised classification system for Chinese Mei Cultivars. But there were still several exceptions: 1) the Guhong Chuizhi inserted between the Tiaoxue Chuizhi and the Danfen Chuizhi; 2) the Wufu Chuizhi kept off the Pink Pendant Form, and the Moshan Chuizhi was removed from Viridiflora Pendant Form; 3) the Danbi Chuizhi and the Shuangbi Chuizhi of Viridiflora Pendant Form got together well but fell within the Pink Pendant Form.

A Proposed Mesh Placement for Repair of Ventral Hernia and Contouring of the Abdomen

Introduction: Abdominal wall defects and muscle redundancy in the form of protruded abdomen still represent a challenging problem. The aim of this article is to reconstruct the abdominal wall and regain the abdominal contour through the application of biosynthetic meshes in certain fashion. Patients and Methods: this is a prospective study done 25 patients with long standing ventral hernia and lax abdominal muscle wall. All patients were performed at Zagazig university hospitals in the period between September 2011 and November 2013. Polypropylene mesh is used for every patient after anatomical hernia repair for hernioplasty and then shaping like outstretched hand (fingers processes). The aim is to reinforce the abdominal wall and reshape the abdomen. Results: regarding to the aesthetic aspect and success rate of the abdominal wall reconstruction, we have a good satisfactory results without recurrence in a period of 2 years follow up. Three patients are suffered from wound infection and partial edge ischemia in two patients. Bleeding and delayed wound healing in ten patients and persistent seroma are occurred in fife patients. Conclusion: It is safe with a good patient satisfaction to combine ventral hernia repair and abdominoplasty in cases with excess skin and musculofascial laxity of the abdominal wall (pendulous abdomen) with application of this finger processes mesh, after following the proper technique and precautions.

Pendulation reduction on ship-mounted container crane via T-S fuzzy model

Ship-mounted container cranes are challenging industrial applications of nonlinear pendulum-like systems with oscillating disturbance which can cause them unstable.Since wave-induced ship motion causes the hoisted container to swing during the transfer operation,the swing motion may be dangerously large and the operation must be stopped.In order to reduce payload pendulation of ship-mounted crane,nonlinear dynamics of ship-mounted crane is derived and a control method using T-S fuzzy model is proposed.Simulation results are given to illustrate the validity of the proposed design method and pendulation of ship-mounted crane is reduced significantly.
