概括

指纹脊密度 (FPRD) 显示性二态,女性的密度更高. 这种方法提供了一种快速,经济高效的方法,可以在大规模伤亡事件中从遗骸中确定性别.

科学领域:

法医科学法医科学法医科学
人类学是人类学.
皮肤刻画的字体.

背景情况:

众所周知,指纹脊密度 (FPRD) 呈现性二态.
雌性通常比雄性拥有更细,更密集的脊柱.
对于从碎片遗骸中确定性别的FPRD的实用性,特别是在大规模伤亡场景中,需要进行评估.

研究的目的:

为了评估指纹脊密度 (FPRD) 的性二态.
评估FPRD在大规模伤亡事件中用于确定性别的适用性.
建立基于FPRD的性别差异化的实际门.

主要方法:

这是一项涉及429个男性和50个女性尸体的横截面观测研究.
通过油墨打印收集的指纹;表皮脊数量测量在5x5毫米面积.
统计分析,包括学生的t测试,用于比较两性之间的脊柱密度.

主要成果:

与男性 (12.18 /25 mm2) 相比,女性 (14.86 /25 mm2) 观察到明显更高的FPRD平均值,p<0.001.
确定了一个实际的门:没有男性FPRD>14,没有女性FPRD<12.
使用所有十个手指的精度提高到~99.0%的性别确定 (男性10-13,女性14-16).

结论:

FPRD是性别的可靠指标,显示出显著的性二态.
对于碎片化遗骸,FPRD方法提供了一个快速,经济高效的性别确定工具.
这种技术有助于识别灾难受害者,因为它可以在其他方法不切实际的情况下快速在现场区分性别.

The Ratio of X Chromosome to Autosomes

The Ratio of X Chromosome to Autosomes

In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

IR Frequency Region: Fingerprint Region

IR Frequency Region: Fingerprint Region

IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...
