1水分胁迫对番茄叶片气孔传导及光合色素的影响显示文摘 以栽培番茄品种AilsaCraig的6叶期幼苗为试验材料,在水培条件下研究了50,75和100g/LPEG水分胁迫对叶片气孔传导、光合色素含量及发叶速度的影响。结果表明,水分胁迫使气孔传导度和发叶速度降低,光合色素增加。气孔传导度和发叶速度的降低均与水分胁迫强度和持续时间有关,而光合色素的增加主要与胁迫持续时间有关。程智慧 孟焕文 Stephen A Rolfe Julie D Scholes 2002西北农林科技大学学报(自然科学版)2002,30,6:32
2Immediate nipple-areola-sparing mastectomy reconstruction: An update on oncological and reconstruction techniques显示文摘Nipple-sparing mastectomy(NSM) is a safe technique in patients who are candidates for conservation breast surgery. However, there is worry concerning its oncological safety and surgical outcome in terms of postoperative complications. The authors reviewed the literature to evaluate the oncological safety, patient selection, surgical techniques, and also to identify the factors influencing postoperative outcome and complication rates. Patient selection and safety related to NSM are based on oncological and anatomical parameters. Among the main criteria, the oncological aspects include the clinical stage of breast cancer, tumor characteristics and location including small, peripherally located tumors, without multicentricity, or for prophylactic mastectomy. Surgical success depends on coordinated planning with the oncological surgeon andcareful preoperative and intraoperative management. In general, the NSM reconstruction is related to autologous and alloplastic techniques and sometimes include contra-lateral breast surgery. Choice of reconstructive technique following NSM requires accurate consideration of various patient related factors, including: breast volume, degree of ptosis, areola size, clinical factors, and surgeon's experience. In addition, tumor related factors include dimension, location and proximity to the nipple-areola complex. Regardless of the fact that there is no unanimity concerning the appropriate technique, the criteria are determined by the surgeon's experience and the anatomical aspects of the breast. The positive aspects of the technique utilized should include low interference with the oncological treatment, reproducibility, and long-term results. Selected patients can have safe outcomes and therefore this may be a feasible option for early breast cancer management. However, available data demonstrates that NSM can be safely performed for breast cancer treatment in selected cases. Additional studies and longer follow-up are necessary to define consistent selection criteria for NSM.Alexandre Mendon?a Munhoz Eduardo Montag José Roberto Filassi Rolf Gemperli 2014World Journal of Clinical Oncology2014,5,3:15
3Copper Adsorption on Olivine显示文摘Copper adsorption on olivine supplied by the A/S Olivine Production Plant at Aheim in western Norway was studied. The factors were evaluated which affect the uptake of copper. It is shown that the equilibrium pH of aqueous solution has the greatest influence on copper adsorption thanks to the competitive adsorption between proton and copper ions, and the adsorption of copper to olivine increases rapidly with pH increasing from 4 to 6. Moreover, initial copper concentration and olivine dose possess significant effect on copper adsorption, for the adsorption rate of copper increases with olivine dose increasing or initial copper concentration decreasing at the same pH. In addition, the ionic strength effect on the adsorption was also investigated, but it owns little effect on the adsorption process of copper due to the formation of inner sphere adsorption of copper on olivine. The experimental data show that olivine has a high acid buffer capacity and is an effective adsorbent for copper.Lei Shao, Rolf A. Kleiv, Kunt L.

4Current aspects of therapeutic reduction mammaplasty for immediate early breast cancer management: An update显示文摘Breast-conservation surgery(BCS) is established as a safe surgical treatment for most patients with early breast cancer. Recently, advances in oncoplastic techniques are capable of preserving the breast form and quality of life. Although most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Among technical options, therapeutic reduction mammaplasty(TRM) remains a useful procedure since the BCS defect can be repaired and the preoperative appearance can be improved, resulting in more proportional breasts. As a consequence of rich breast tissue vascularization, the greater part of reduction techniques have based their planning on preserving the pedicle of the nipple-areola complex after tumor removal. Reliable circulation and improvement of a conical shape to the breast are commonly described in TRM reconstructions. With an immediate approach, the surgical process is smooth since both procedures can be carried out in one operative setting. Additionally,it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reduces the incidence of margin involvement. Regardless of the fact that there is no consensus concerning the best TRM technique, the criteria is determined by the surgeon's experience, the extent/location of glandular tissue resection and the size of the defect in relation to the size of the remaining breast. The main advantages of the technique utilized should include reproducibility, low interference with the oncological treatment and long-term results. The success of the procedure depends on patient selection, coordinated planning and careful intra-operative management.Alexandre Mendona Munhoz Eduardo Montag Rolf Gemperli 2014World Journal of Clinical Oncology2014,5,1:5
5基于真实微观组织的双相钢力学行为多尺度模拟显示文摘以两种不同化学成分和马氏体含量的双相钢为研究对象,对其显微组织进行了有限元建模。选取一部分显微组织作为代表性单元RVE来反映宏观材料特性,考虑合金成分和铁素体晶粒尺寸的影响,采用基于位错强化理论的Bailey-Hirsch模型描述铁素体和马氏体单相的流变行为,在ABAQUS中模拟了RVE的单向拉伸过程。结果表明,多尺度模型可以较好的预测宏观力学性能,并能合理的反映双相钢变形过程微观尺度的应力应变行为。张志建 Asgari S A Rolfe B F 2016塑性工程学报2016,23,5:3
