The head is positioned erect for an approximation; yet most facial soft tissue depths (FSTD) used are measured from supine subjects. Depth difference might be significant, but there is a paucity of data to verify. This study compared erect and supine values for 17 landmarks from 30 healthy New Zealand (European population affinity) women (18–30 or 40–55 years) in erect then supine positions. Height, weight, and sonographic FSTD data, totaling 1020 measurements, were obtained. Three midline and seven averaged bilateral values were compared using ANOVA, p values, and Pearson's correlations. Correlative strength of age and body mass index, BMI (kg/m2), was determined by values. Results showed averaged erect and supine differences were significant for four of ten FSTDs. Between individuals, difference was various and not unidirectional. In conclusion, depth differences were observed but not all significant or unidirectional, BMI significantly influenced nine FSTD values, but age group did not.  相似文献

Eleven deaths from crocodile attacks in the Northern Territory, Australia were reviewed. The male:female ratio was 8:3; age range—10–62 years, average 29.4 years. Four children were included (one boy and three girls, aged 10, 11, and two at 12 years), and there were seven aboriginal victims (64%). The attacks were witnessed in eight cases with the victims swimming in freshwater N = 5, standing on a river bank N = 1, fishing in fresh water N = 1, or diving in the sea N = 1. At autopsy, several distinct patterns of injury were observed ranging from complete traumatic disruption of the body with only incomplete remains for examination (N = 5), to crushing of the head with fractures of the skull (N = 4), crushing of the chest with fractures of the ribs and sternum (N = 2), and avulsion of limbs (N = 4). In one case, there was decapitation. Autopsy evaluations were complicated by decomposition and loss of body parts.  相似文献

Diagnosis of drowning remains a difficult issue in current forensic sciences. A large number of diatoms were lost by removing the supernatant after centrifugation in the conventional forensic diatom test. We developed a novel membrane filtration method to enrich diatoms from samples. A new solution using different ratios of acetic acid and eugenol is prepared to make the membrane transparent. These processes allow the diatom‐containing membrane to be visualized and identified easily by light microscopy. The tissues contaminated by water rich in diatoms were detected by the new method for the recovery of diatoms. Eleven drowning cases were analyzed by both the new method and the conventional method to compare the sensitivity of both methods. The recovery of the novel diatom test method was 54.2 ± 23.1%. The positive rate of the novel method has been proven to be superior to the conventional method in the diagnosis of drowning.  相似文献

在法医学检案中,溺死诊断以及入水地点的判定一直是重点和难点之一,硅藻检验被认为是一种相对可靠的诊断溺死的方法,而根据硅藻的群落特征推断其入水区域具有一定的可信度。对不同水域内硅藻进行研究,可为溺死鉴定及入水区域的判定提供参考。本文就硅藻相关的生物学特性、检验方法等相关的国内外研究进展进行综述,供法医学工作者在相关科研和检案实践中参考。  相似文献

政府绩效评估指标设计在整个政府绩效评估过程中居于核心地位,指标设计应遵循业绩指标与通用指标相结合、定性指标和定量指标相结合、传统指标与现代指标相结合、正数指标与负数指标相结合、基本指标与修正指标相结合、过程指标与结果指标相结合的开发思路。  相似文献

In this paper we present the research results of key factors that determine the investment behavior of Russian companies during 2004-2008. The emphasis is made on the policy of capital expenditures. In the analysis, it included maeroeconomic, some industry factors (growth rate, spread of efficiency (ROIC-WACC), market and industry risks) as well as some internal factors related to the equity structure and the quality of corporate governance.  相似文献

This article looks beyond Z-score and proposes a novel methodological framework to build an all-encompassing indicator of bank stability for individual banks using the optimisation-based ‘benefit-of-the-doubt (BoD)’ approach. Unlike other available approaches, this approach is totally data-driven and generates endogenous weights to aggregate sub-indicators of bank stability and dimensions. Further, the final outcomes are not limited to a scalar measure of bank stability. The unique optimal weights offer valuable policy-relevant insights and highlight the most precarious areas of stability, which demand the immediate attention of the bank's management and the industry regulators for both micro-and macro-level policymaking. Using the data of Indian public sector banks operating in the year 2018, the study illustrates the proposed framework to obtain a holistic indicator of bank stability, defined on 14 ratio sub-indicators and 5 broad dimensions (soundness, asset quality, profitability, management efficiency, and liquidity) of bank stability.  相似文献

Studies which estimate the postmortem interval (PMI) based on diatoms or bacterial communities have been well‐conducted. However, predicting the PMI based on microorganisms has limited accuracy. The objective of this study was to discover specific biomarkers for estimating the PMI for drowning. The in vivo experimental model consisted of rats classified into nine groups (seven drowned groups from Day 1 to Day 7 and two control groups). Their lung tissues were analyzed for the receptor for advanced glycation end products (RAGE) mRNA expression determined by qRT‐PCR. RAGE protein levels were determined by Western blotting and immunohistochemical (IHC) staining. RAGE mRNA and protein levels gradually degraded over time. Immunostaining analysis revealed that RAGE in the Day 1 sample was significantly higher than that in the Day 6 or Day 7 samples. These results indicate that RAGE in drowned lungs could be a potential biomarker for the determination of the PMI after drowning.  相似文献
