The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization.  相似文献

ABSTRACT

Many liberals have been immodest in postulating that their own progressive, secular liberalism is the only one that can be justified in public reason. In Liberalism’s Religion, I articulate a more modest theory of liberalism and religion. While I personally endorse progressive secular liberalism, I argue that it is only one of the reasonable conceptions of liberal justice. This liberal modesty has profound, hitherto unnoticed implications for (i) the role of religious arguments in the public sphere, (ii) the legitimacy of religious establishment, and (iii) the justifiability of religious exemptions. In this article, I defend these three claims by providing replies to my critics.  相似文献

柔嫩艾美球虫杨凌株表面抗原SAG10基因的克隆与原核表达   总被引:2,自引:0,他引:2  
从柔嫩艾美球虫第二代裂殖子总RNA中扩增EtSAG10基因,与pGEM-T Easy载体连接后转化大肠杆菌(E.coli)DH5α,筛选阳性克隆,扩增不含N端信号肽的编码序列,分别插入表达载体pET-32a( )和pMAL-c2X,转化至E.coliRosetta,以IPTG诱导表达。结果表明,pET-32a( )-EtSAG10在E.coliRosetta中的表达产物约占菌体总蛋白的43%,融合蛋白分子质量约为47 ku,以包涵体形式存在;而pMAL-c2X-EtSAG10在E.coliRosetta中表达的重组蛋白为可溶性,表达产物约占菌体总蛋白的35%,融合蛋白分子质量约为69 ku。以表达的可溶性EtSAG10重组蛋白100μg/只肌肉注射免疫雏鸡,攻虫后以盲肠病变计分、盲肠卵囊数(OPG)、相对增重率和抗球虫指数(ACI)评价,免疫组相对盲肠卵囊产量为47.7%,抗球虫指数由86.79提高至152.13。提示,重组表达的EtSAG10可诱导雏鸡产生一定的抗球虫免疫保护。  相似文献

江泽民同志关于维护社会稳定的一系列论述,是十三年来中国共产党第三代中央领导集体坚定不移地贯彻邓小平关于“稳定压倒一切”的思想,正确处理改革、发展、稳定的三者关系,领导全国人民建设中国特色社会主义伟大实践的科学总结,是在实践基础上的理论创新。(一)全面而深刻地揭示了改革、发展、稳定三者的“内在联系”。一是改革、发展、稳定共处于一个统一体,是辩证统一的关系。二是改革、发展、稳定三者间存在着一种总的联系,“把改革的力度、发展的速度和社会可承受的程度统一起来”是其中最有规律性的联系;而“不断改善人民生活”则是这种“总的联系”中的重要结合点。(二)在理论上已初步形成了较为完整的观念体系。一是具备了理论认识价值;二是生成了一系列论述观点的概念集合;三是提出了检验其理论的实践标准。(三)在实践上回答了正确处理改革、发展、稳定三者关系的一系列重大问题,制定了一整套策略措施。一是总揽全局,整体推进;二是注重关联,把握过程;三是抓住关键,巩固基础;四是先务当务之急,不务不急之务;五是为之于未有,治之于未乱。  相似文献

文化变迁是一场纷繁复杂、生动万千的过程 ,不是某种文化在同一时间全部发生变迁。从纵向看 ,文化变迁的速度越来越快 ;从横向上看 ,文化变迁始于文化中某个成分的变化。一个民族与周围民族的交往 ,往往会打破其文化运作的均衡状态 ,又终因文化的整体性特征而形成新的平衡。由于民族间及国家间交往的频繁 ,文化变迁中的自变量越来越难以预测  相似文献

目的探讨多层螺旋CT(MSCT)沿鼻骨斜面多平面重组(MPR)技术在鼻骨线性骨折法医学鉴定中的应用价值。方法以MSCT轴位平扫和沿鼻骨斜面多平面重组(MPR),对98例头面部外伤患者进行检查。结果 MSCT轴位平扫诊断:鼻骨正常和线性骨折(单侧或双侧)分别为29例和69例,阳性率70.4%。MSCT沿鼻骨斜面多平面重组(MPR)复诊:鼻骨正常的和线性骨折分别为19例和79例,阳性率80.6%。结论采用MSCT沿鼻骨斜面多平面重组技术可发现常规MSCT轴位平扫未能检见的鼻骨线性骨折,对法医学鉴定具有更高的应用价值。  相似文献

Research on election integrity has noted the important role of election administration in facilitating free and fair practices. However, limited research has assessed how the staffing of polling station level election commissions may influence voting. Using extensive personnel and election data from Ukraine, this article investigates how partisanship and liberal registration rules permit major parties to “stack” election commissions with sympathetic officials. The empirical analysis demonstrates that the placement of representatives from major parties, or affiliated parties, in leadership positions on polling station commissions is associated with improved election outcomes.  相似文献

Virtual anthropology (VA) is based on applying anthropological methods currently used to analyse bones to 3D models of human remains. While great advances have been made in this endeavour in the past decade, several interrogations concerning how reliable these models are and what their proper use should be remain unanswered. In this research, a fundamental assumption of VA has been investigated: if the way we perceive and apply an anthropological method is truly similar when looking at bones macroscopically and through various 3D media. In order to answer, 10 skulls of known age and sex were scanned using a computed tomography (CT) scanner and a 3D surface scanner. Two observers separately applied a defined staging method to eight suture sites on these skulls, first looking at the bone macroscopically, then at the 3D surface scan, and finally on the CT scan. Two rounds of observation were carried out by each observer. Intra- and inter-observer error were evaluated, and two sample t-tests used to evaluate if the different types of medium used yielded significantly different observations. The results show a high degree of inter-observer error, and that data obtained from 3D surface scans differ from macroscopic observation (confidence level 95%, P ≤ 0.05). CT scans, in these settings, yielded results comparable to those obtained through macroscopic observations. These results offer many possibilities for future research, including indications on the kind of anthropological methods and anatomical landmarks that might be reliably transferable to the virtual environment. All current methods used in traditional anthropology should be tested, and if they prove unreliable, new techniques to analyse bones from virtual models should be developed.

Key points

  • Large discrepancies between observation on dry bones and computer-generated 3D models (surface scans or CT scans) could lead to the re-evaluation of the suitability of traditional anthropological methods for application on 3D models.
  • This preliminary study evaluates whether macroscopic, 3D surface scans, and CT scans viewings generate different observations.
  • The results indicate that the data are not always coherent across all three media of observation.
  • Explanations include the aspect given to the bone by the 3D software, differences between handling bones in real life versus on a computer, and level of expertise of the observers.
