Timewise temperature variations in objects that are undergoing unsteady heating or cooling is a commonly encountered problem in the thermal sciences. One particular area of application is the cooling of a body post-death and the use of body temperatures to estimate the time of death. Here, a new approach based on the theory of transient heat transfer is formulated to allow efficient calculation of unsteady conduction problems. The theoretically derived unsteady temperature models are compared with experimentally based correlations (the Marshall-Hoare-Henssge model). The two approaches are found to agree very well. With this new theoretically based approach, timewise temperature variation can be calculated for both large and small Biot number transient problems. 相似文献

Blood-contaminated shoeprints and footmarks contain valuable operational information as they may bind an individual who stepped in the crime scene with the incident and not merely with the location. As determining the age of a bloodstain remains a challenge, while processing the scene, it is difficult to determine whether the blood is completely, or partially, dry. Thus, executing a dye staining protocol may wash these marks away as they might still be soluble. However, to meet this challenge, it is possible to fix blood marks using heat. This study aims to find a solution for floor surfaces covered by heavier blood traces (shoeprints and footmarks). For this purpose, a new pseudo-operating device was constructed for examining the blood-fixing process of both mentioned trace types. Two trials were performed with depletion marks. The results revealed that fully developed fresh and heavily blood deposits were obtained by heating to 200°C for 7.5 min using the fixing device, followed by a staining protocol using amido black solution. The achieved sharp resolution of the examined bloody prints demonstrates that in certain cases the dehydration mechanism of heating is preferred over precipitating the proteins attributed to 5-sulfosalycilic acid; thus, reducing the risk of washing blood evidence while processing the crime scene. 相似文献

The majority of scholarly research on Rwanda currently focuses on determining the causes of and participation in the genocide.
In this paper, we explore a variety of questions that have come to the forefront in post-genocide Rwanda. In particular, we
are concerned with the prospects for peace and justice in the aftermath of the gross abuses of human rights that occurred
and, to that end, we consider the potential uses and limits of restorative justice initiatives in the process of healing and
reconciliation in Rwanda. We argue that restorative justice initiatives have moved the country closer toward reconciliation
than retributive measures, such as the International Criminal Tribunal for Rwanda. That said, we also suggest that the Rwandan
government, despite claims that it seeks to achieve reconciliation, has not shown a serious commitment to healing the wounds
that persist between either individual Rwandans or the groups that they comprise. In the end, then, we make a case for the
importance of pairing a comprehensive search for justice in Rwanda with a commitment to truth-telling and accountability by
the victims and perpetrators of the genocide, as well as by current government officials. 相似文献

National Council of Juvenile and Family Court Judges Passes a Set of Practice Reform Resolutions 下载免费PDF全文

The National Council of Juvenile and Family Court Judges (NCJFCJ) recently passed resolutions and policy statements on how to improve the lives of youth and families involved with juvenile or family courts. These resolutions address the needs of homeless youth and their families, juvenile probation and adolescent development, and the need for independent oversight of youth confinement facilities. 相似文献

Haplotype, allele frequencies and population data of eight Y-chromosome STR loci, DYS437, DYS438, DYS439, GATA A10, GATA A7.1, GATA A7.2, GATA C4 and GATA H4, were determined from a sample of 212 unrelated male individuals from Galicia (NW of Spain). 相似文献

The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study. Haplotype and allele frequencies of these eight Y-STRs were estimated in all samples. The lowest haplotype diversity was found in the Lara (Argentina) population (95.44%) and the highest (99.90%) in Macao (China). Pairwise haplotype analysis showed the relative homogeneity of the Iberian origin samples, in accordance with what was previously found in the European populations for other Y-STR haplotypes (http://www.ystr.org). As expected, the four non-Caucasian samples, Macao (Chinese), Mozambique (Africans), Costa Rica (Africans) and Argentina (Lara, Amerindians), show highly significant Phist values in the pairwise comparisons with all the Caucasian samples. 相似文献

Sudden unexplained death among persons 1-35 years old 总被引:1,自引:0,他引:1
Sudden unexplained death (SUD) on children and young people is unusual, although the real magnitude is unknown. The clinical and physiopathological characteristics are poorly defined. The aim of this work is to analyse the epidemiological, clinical and pathological characteristics of SUD on children and young people. In this population observational study, all sudden non-violent deaths between 1 and 35 years occurred in Bizkaia (north Spain) from 1991 to 1998 were investigated, analysing those diagnosed as SUD. Pathological records, circumstances of death and autopsy findings were obtained. Out of 107 cases of sudden death (SD), 19 were SUD. The mortality rate of SUD was 0.43/100,000 persons per year. Five had pathological antecedents: syncopal episodes in three cases and tachycardia and ventricular extrasystoles one each. The initial symptom was sudden collapse (N=13). In four cases, a precipitating factor was identified (two physical exercise and two emotional stress). Six cases died during sleep. Minimal pathological findings in coronary arteries, myocardium or conduction system was found in nine cases. Heart weight increased (under interval of confidence of 95%) was present in 12 cases. In conclusion, the SUD is very infrequent in children and young people. However, it has great clinical significance because it affects people in good health and occurs without warning symptoms. Some of these cases can be due to cardiac arrhythmias. In deaths in bed there is a high frequency of SUD. In the future, it may be possible that abnormalities at a molecular level will be detected in some of the cases identified today as SUD. 相似文献

The aim of this pilot study was to examine the feasibility of an interactive computer program among 34 sixth and seventh grade children and to assess the potential for knowledge acquisition about puberty. Based on a developmental self-esteem approach to teach children about their bodies, the Body Morph program was designed to maximize the educational experience by: (1) tailoring puberty information to boys or girls, and (2) creating a confidential experience. Preliminary results indicated that students significantly improved their knowledge about puberty after using the program. Satisfaction among boys and girls for this type of educational approach suggests that it is a compelling format from which to learn about puberty.This research project was funded with the support of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) 1R43DK061269-01A2 to develop an educational computer program to improve body image in middle schoolers. 相似文献
