Fluorescence of a Natural Fluorophore as a Key to Improve Fingerprint Contrast Image

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.

柔嫩艾美球虫杨凌株表面抗原SAG10基因的克隆与原核表达

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。     

地上权制度之历史研究——兼评我国地上权立法

地上权制度是用益物权制度框架内的一项基本制度,经济和社会的发展使地上权具有了崭新的内容,在我国土地所有权归国家和农村集体经济组织所有的条件下具有广泛的适用范围,尤其是有助于解决城市用地、工业用地、居民住宅建设用地,以及在他人所有的土地上下铺设管道等公共设施而产生的权利义务关系,从而促进社会经济的发展。     

趋势面拟合在机场噪声监测评价中的应用

机场周围飞机噪声的噪声级LWECPN数据来自网格布点监测,这些数据可视为连续曲面上的离散点。寻求利用有限的监测数据,拟合机场周围飞机噪声影响区域内噪声级的曲面分布,根据噪声级精确度允许误差的要求,采用统计检验的方法,确定拟合函数模型的精确度,从而得到机场周围飞机噪声的噪声级等值线分布图。

上、下尖牙髓腔/牙体表面积比值的年龄判定价值研究

目的通过三维重建测量上、下颌尖牙髓腔/牙体表面积比值(Pulp/Tooth area Ratio,PTR)来推断个体年龄,为临床年龄推断的应用提供科学依据。方法收集口腔门诊患者年龄在16~65岁200例锥形束CT(Cone beam computed tomography,CBCT)影像资料,以4个尖牙为测量对象并进行三维重建,测量各尖牙髓腔和牙体表面积,计算PTR值。应用SPSS17.0软件进行统计学分析,推导实际年龄的推断公式。结果Pearson相关分析显示上、下颌尖牙PTR值与实际年龄呈高度负相关(P<0.001,r值为-0.833~-0.891)。4个尖牙间的PTR值无显著差异(P>0.05)。男女性别间尖牙PTR值无显著差异(P>0.05)。尖牙PTR值(x)推断年龄公式为:年龄=84.42-222.22x,R²=0.739。结论检测尖牙的PTR值,可明显提高临床年龄推断的准确性。     

Blood and bone: body mass,gender and health inequality in nineteenth-century British families

In mid-nineteenth-century Britain, a new institution emerged: the modern prison. Some prisons invested in scales. Upon entry, prisoners were measured and personal details documented. These meticulously compiled records afford a new vantage point from which we can peer into the dynamics of the household. Body measurements – height, weight, and body mass (weight adjusted for height) – connect to both patterns of consumption and health risk. Prison data thus speak to both gender and health inequality in the past. The paper juxtaposes a service economy (Wandsworth near London) with a modern manufacturing sector (Paisley near Glasgow) in order to contrast how economic form and opportunities in the market sector shaped relations and outcomes in the household sector. We find that families bargained over the allocation of resources; that bargaining position was influenced by economic value, mediated by maternal sacrifice; that this was an earner bias rather than gender bias; and that new industrial work for women and children supported a more egalitarian distribution that improved everyone's health status via superior heights and heavier weights. We examine Irish immigrants to assess cultural differences in family behaviour. Finally, the paper offers, for the first time, a detailed interpolation of Waaler's health risk for women.     

Assessment of Maceration Techniques Used to Remove Soft Tissue from Bone in Cut Mark Analysis

Maceration techniques employed in forensics must be effective without compromising the bone's integrity and morphology, and prevent destruction of evidence. Techniques must also be fast, safe, easily obtainable and inexpensive; not all techniques currently employed are appropriate for forensic use. To evaluate the most suitable approach, seven techniques including current and new methodologies were applied to fresh, fleshed porcine ribs exhibiting cut marks. A sample size of 30 specimens per technique was examined under scanning electron microscopy at the cut mark and the surrounding uncompromised regions; a scoring system of effectiveness was applied. The previously unpublished microwave method fared best for bone and cut mark preservation. Sodium hypochlorite destroyed cut marks, and was deemed unsuitable for forensic analysis. No single technique fulfilled all criteria; however, this study provides a benchmark for forensic anthropologists to select the most appropriate method for their situation, while maintaining the high standards required by forensic science.     

地区构成的世界——卡赞斯坦的地区主义理论

从地区视角来建立国际体系理论是国际政治理论一个新的发展方向。卡赞斯坦创造性地以地区为单位建立了地区世界的理论。其基本观点是,以多孔化地区为基本单位的美国帝权体系已基本成形,该体系处于地区化、国际化和全球化的进程之中,体系与单位在三种进程中、在帝权-核心国家-地区的纵向联系中相互塑造和重塑,其中包含了重要的社会性关系。“地区构成的世界”进一步丰富和发展了单位层面的建构主义理论,但是在基本假定、分析框架和逻辑结构中都存在明显的缺陷。
