目的:在分析区域包含整个颅顶骨的前提下,改变颅顶骨显微CT(micro-computed tomography,Micro-CT)扫描后二维图像的重建层数或者位置,比较进行重建后的骨量参数(骨表面积、骨体积)是否出现改变。方法:4日龄小鼠颅顶骨培养后置于含培养液的EP管中,进行连续Micro-CT扫描。根据重建时改变层数或位置来分别分析:(1)996~22层组与800~50层组,分析层数不同(n=3);(2)996~22层组与随机选择层组,分析层数不同(n=3);(3)近边界上缘组与近边界下缘组,分析层数相同(n=3)的骨量参数变化。结果:在分析区域包含整个颅顶骨的前提下:(1)增加或者减少层数导致骨表面积变化(F=47.798,P=0.002),而骨体积无变化(F=7.083,P=0.056)。(2)随机选择层数组与996~22层数组分析比较时骨表面积(F=359.392,P=0.000)、骨体积(F=51.844,P=0.002)均有变化。(3)重建层数相同的前提下,改变分析区域位置时骨表面积(F=0.000,P=0.991)、骨体积(F=0.000,P=0.995)无变化。结论:(1)Micro-CT三维重建时,改变重建层数可影响骨量参数。(2)Micro-CT三维重建时,随机选择重建层数可影响骨量参数。(3)Micro-CT三维重建时,保证分析层数相同而改变空白分析区域的位置不会影响骨量参数。

Lithium metal batteries (LMBs) and anode-free LMBs (AFLMBs) present a solution to the need for batteries with a significantly superior theoretical energy ***,their adoption is hindered by low Coulombic efficiency (CE) and rapid capacity fading,primarily due to the formation of unstable solid electrolyte interphase (SEI) layer and Li dendrite growth as a result of uneven Li plating.

Load shedding is a major problem in Central Africa, with negative consequences for both society and the economy. However, load profile analysis can help to alleviate this problem by providing valuable information about consumer demand. This information can be used by power utilities to forecast and reduce power cuts effectively. In this study, the direct method was used to create load profiles for residential feeders in Kinshasa. The results showed that load shedding on weekends results in significant financial losses and changes in people’s behavior. In November 2022 alone, load shedding was responsible for $ 23,4 08,984 and $ 2 80,9 07,808 for all year in losses. The study also found that the SAIDI index for the southern direction of the Kinshasa distribution network was 122.49 hours per feeder, on average. This means that each feeder experienced an average of 5 days of load shedding in November 2022. The SAIFI index was 20 interruptions per feeder, on average, and the CAIDI index was 6 hours, on average, before power was restored. This study also proposes ten strategies for the reduction of load shedding in the Kinshasa and central Africa power distribution network and for the improvement of its reliability, namely: Improved load forecasting, Improvement of the grid infrastructure, Scheduling of load shedding, Demand management programs, Energy efficiency initiatives, Distributed Generation, Automation and Monitoring of the Grid, Education and engagement of the consumer, Policy and regulatory assistance, and Updated load profile analysis.

Introduction: Nursing ethical sensitivity refers to a nurse’s capacity for thoughtful consideration of ethical issues when faced with dilemmas. In the nursing domain, ethical dilemmas arise when nurses face challenges in making sound ethical decisions during clinical practice. These challenges may stem from conflicts between personal values and professional responsibilities. Methodology: Articles downloaded from Pub Med, CNKI, and Google Scholar were reviewed. Results: After rigorous screening, a meticulous analysis was conducted, encompassing 10 articles and involving a substantial cohort of 2863 participants. Existing literature revealed variations in the ethical dilemmas faced by nurses across different departments. The ethical sensitivity of nurses also varies, with higher ethical sensitivity correlating with stronger empathetic abilities. Zhen et al. classified the causes of ethical dilemmas into four main categories: (1) Ethical dilemmas arising from personal reasons of nursing students;(2) Ethical dilemmas stemming from the actions of teachers;(3) Ethical dilemmas triggered by patients;(4) Ethical dilemmas resulting from miscellaneous reasons. Conclusion: According to literature findings, nursing ethical sensitivity was positively linked to the nurse’s ethical decision-making ability. A case study-oriented teaching program has proven effective in enhancing ethical sensitivity among nursing students.
