Objectives:To determine the factors influencing the occupational well-being of experienced nurses.Methods:We interviewed eight experienced nurses using an exploratory,semi-structured interview.Results:The interviews revealed five themes that influenced occupational well-being in experienced nurses:(1)external occupational recognition;(2)internal career expectation and occupational value;(3)workenvironment;(4)family support;and(5)occupationalplanningand payment.When the nurses were not recognized by patients or clients,their family,colleague and leaders,their well-being was negatively impacted.However,the harmonious work environments and friendly interpersonal relationships positively impacted their well-being.Conclusion:By identifying the factors that contribute to a nurse's occupational well-being,the nursing management is better able to address the nurse's needs to maintain a positive well-being.This in turn will decrease the burnout and increase retention of experienced nurses,which will raise the quality of patient care.

Single later blastula nuclei from AB strain of zebrafish (Danio rerio) were transplanted into enucleated unfertilized eggs of Long fin strain. Of 1119 cloning embryos, 14 reconstructed embryos developed into fry. DNA fingerprinting systems of the cloned fish were similar to those of the nuclear donor fish, but were distinctly different from those of the nuclear recipient fish. It confirmed that the genetic material originated from nuclear donor cell other than from nuclear recipient egg. The research suggested that the basic technique for nuclear transplantation performed with different strains of zebrafish has made a breakthrough. It should be helpful for the study of some important developmental problems such as gene function, the regulation of gene expression during animal development, the developmental potential of a nucleus and the interactions between the donor nucleus and the recipient cytoplasm, etc.

Using a nuclear transplantation approach, the integration and expression of the green fluorescent protein (GFP) gene in the embryogenesis of transgenic loach (Misgurnus anguillicaudatus Cantor) have been studied. The GFP gene expression is first observed at the gastrula stage, which is consistent with the initiation of cell differentiation of fish embryos. The time course of the foreign gene expression is correlated with the regulatory sequences. The expression efficiency also depends on the gene configuration: the expression of pre-integrating circular plasmid at early embryos is higher than that of the linear plasmid. The integration of the GFP gene is first detected at the blastula stage and lasts for quite a long period. When two types of different plasmids are co-injected into fertilized eggs, the behavior of their integration and expression is not identical.

The laws of influence of different factors have been analyzed in order to enhance the working efficiency and fatigue life of the cleaning element in brush shape of the sugarcane harvester. Based on the principle of orthogonal experiment design, the virtual-orthogonal-experimental analysis for the cleaning element is carried out on the finite element analysis （FEA） software-ANSYS after analyzing the nonlinear structural behavior in the working procedure. The results are analyzed with the overall balancing method, and then the optimal combination is got, which is made up of different levels of different factors. Also the optimal combination of design parameters of the cleaning element received fiom the virtual experimental analysis is conducted an experiment to confirm that the virtual analysis model and results are right, and the effect of factors on the function of the cleaning element is obtained by more analysis and further optimizing.

Hexagonal microtubes with hexagonal phase Y（OH）3 were successfully synthesized by a facile solvothermal method at 160°C for 12 h in the absence of surfactants or templates via a crystal transformation route. Scanning electron microscopy （SEM） results demonstrate that the prepared hexagonal microtubes are with a wall thickness of 50-100 nm, an outer diameter of 1 μm, and lengths going up tens of micrometers. Cubic phase Y2O3 microtubes were obtained after thermal treatment of the Y（OH）3 microtubes at 700 oC for 4 h. Eu^3＋-doped Y2O3 microtubes with strong red emission at 610 nm were also prepared and their photoluminescence （PL） properties were studied. The possible mechanism for the formation of the microtubes was briefly discussed.

现有的抗拔群桩变形计算方法具有理论假定的近似性,而且不能充分考虑群桩基础中各桩基相互加筋效应的影响,造成抗拔群桩变形计算理论落后于抗拔群桩的工程实践。为解决这一问题,本文基于薄壁同心圆筒剪切变形模式和弹性理论,推导得到能考虑群桩基础中桩基相互加筋效应的抗拔群桩变形的解析解。将解析解的计算结果与有限元分析结果、模型试验数据进行对比,结果表明理论解答能较好地计算抗拔群桩的变形。本文方法计算群桩相互作用符合群桩系统的工程实际情况,因此本文理论方法具有很高的理论和实际工程价值,在大规模抗拔群桩的变形分析和设计实践中具有很好的应用前景。

热处理过程中的碳化物转变对高温合金的力学性能影响显著。采用XRD、SEM、EPMA、TEM等研究了Co-Cr-Nb-W耐磨合金热处理过程中碳化物的析出类型、分布特征、演变机制及其对高温拉伸性能的影响。Co-Cr-Nb-W耐磨合金主要在钎焊和时效热处理后使用,该过程中主要发生如下2个碳化物转变过程:MC+matrix=M_(6)C和M_(23)C_(6)+matrix=M_(6)C。合金在高温拉伸应力下的断裂机制为韧脆混合机制,块状初生碳化物与基体之间的界面容易成为裂纹萌生源。热处理过程消除了容易引起晶界迁移的片层状共晶M_(23)C_(6),在骨架状MC周围析出了细小的M_(6)C,同时改善了枝晶间元素偏析,促进基体中形成高密度的交叠层错带,使得合金在1000℃下的抗拉强度提高约20 MPa。

桩基除了承受自身上部建筑物的荷载外,经常还承受各种形式的边载作用。边荷载会引起桩周土体的沉降,产生额外附加力,即负摩阻力。这些可导致桩基的承载力下降使结构破坏。通过建立桩土共同作用的三维数值模型,分析边载作用下桩基承载性能。主要研究了边载大小和边载距离对桩侧摩阻力的影响规律;桩长和边载距离组合对其的影响规律;得出了2个组合关系的表达式。同时应用最小二乘法得到不同边载组合的桩侧总摩阻力表达式,并依据离散系数的统计分析,验证了该函数表达式具有较高的精确度。得到结论:当边载距离s和边载大小Q的相对关系k值增加至32时,由边载产生的桩侧负摩阻力趋于0;当桩长L和边载距离s的相对关系c值增加至0.5时桩侧负摩阻力趋于0。即在这2个相对关系极限值以外,桩基承载性能将不受边载影响。
