The results of extraction of lambda-cigalotrin from dioxan aqueous solutions by hydrophobic organic solvents are presented. It is shown that the degree of extraction depends on the nature of the extractant, the water to dioxan ratio, and saturation of the water-dioxan layer with the electrolyte. The highest efficiency of lambda-cigalotrin extraction was achieved using chlorophorm as a solvent under desalination conditions. The extraction factor was calculated necessary to obtain the desired amount of lambda-cigalotrin from the water-dioxan solution (4:1) with the help of the extractants being used. 相似文献

Suicide by asphyxiation using helium is the most widely-promoted method of "self-deliverance" by right-to-die advocates. However, little is known about persons committing such suicides or the circumstances and manner in which they are completed. Prior reports of suicides by asphyxiation involving helium were reviewed and deaths determined by the North Carolina Office of the Chief Medical Examiner to be helium-associated asphyxial suicides occurring between January 1, 2000 and December 31, 2008 were included in a new case series examined in this article. The 10 asphyxial suicides involving helium identified in North Carolina tended to occur almost exclusively in non-Hispanic, white men who were relatively young (M age = 41.1 T 11.6). In 6 of 10 cases, decedents suffered from significant psychiatric dysfunction; in 3 of these 6 cases, psychiatric disorders were present comorbidly with substance abuse. In none of these cases were decedents suffering from terminal illness. Most persons committing suicide with helium were free of terminal illness but suffered from psychiatric and/or substance use disorders. 相似文献

Recent published research has lead to improved techniques for recovering latent fingermarks from metallic surfaces. The present study corroborates and extends some of the work carried out by Bond [1], [2], [3], but an alternative mechanism is proposed for the thermal visualisation of fingermarks based on differential oxidation and the production of interference colours that improve contrast. Fingermarks treated at low temperature could be reheated to enhance recovery, but an upper temperature limit occurs beyond which the mark degrades. The mechanism of enhancement is discussed. 相似文献

It is shown that for verification of human sperm presence on the spots on material evidence it is feasible to apply solid phase enzyme immunoassay (EIA) with the kit "PSA-EIA-BEST T-8458" which is used in clinical practice for diagnosis of prostatic cancer and some other diseases. The method is specific and highly sensitive, convenient for objective registration and computer processing. It is also cost-effective and provides not only significant identification of sperm on the exhibits but also its human origin in complete absence of spermatozoa on the spot. 相似文献

The authors present a method of hingamine identification in non-biological substances (tablets, powder, syringes) and biological fluids (blood, urine). Isolation was made with chloroform in pH 10. Identification was conducted with thin-layer chromatography, gas chromatography/mass-spectrometry, high-performance liquid chromatography, spectrophotometry in UV region. The quantity was estimated with spectrophotometry in UV region, high-performance liquid chromatography and high-performance thin-layer chromatography. The results of the three methods are comparable. 相似文献

We studied the trend in the number of forensic-medical examinations in trials against obstetricians and gynecologists conducted in Primorsky Region in 1997-2005. Most typical defects in obstetric-gynecological care are characterized. These cases are analysed in terms of forensic-medical practice. Detection and forensic-medical analysis of the above defects contribute to optimization of the diagnosis and treatment both in obstetric-gynecological practice and in wide medical practice. 相似文献

How do we think about mass murder? While the principle of responsibilityprovides an effective mechanism for the repression of mass murder(notably through Article 25 ICCSt.), analysis of the actingout of mass murder by perpetrators requires a criminologicalperspective. Analysis of criminogenic processes, and of genocidallogic, helps us go some way in understanding how perpetratorsact out mass murder. Such an approach also leadsus to identify a long silence in the social sciences: mass murderhas become a legitimate field of social scientific study onlyrecently; it also has the advantage of exposing the shortcomingsof many concepts. This article deals with works focusing onmass murder and suggests new research paths inthe social sciences. 相似文献

Bond and Uysal (this issue) complain that expert lie detectors identified by O'Sullivan and Ekman (2004) are statistical flukes. They ignore one class of experts we have identified and misrepresent the procedures we use to identify the others. They also question the psychometric validity of the measures and protocol used. Many of their points are addressed in the chapter they criticize. The fruitfulness of the O'Sullivan-Ekman protocol is illustrated with respect to improved identification of expert lie detectors, as well as a replicated pattern of errors made by experts from different professional groups. The statistical arguments offered confuse the theoretical use of the binomial with the empirical use of the normal distribution. Data are provided that may clarify this distinction. 相似文献

This study examined whether female-to-male (FTM) psychological aggression predicted men’s relapse of substance use disorder
(SUD) 6 months following substance use treatment. Men diagnosed with either a substance abuse or dependence disorder who had
recently begun an SUD treatment program participated in the study with their female relationship partners (N = 173). Logistic regression was used to examine the relationship between baseline FTM psychological aggression and SUD relapse
when controlling for baseline demographic, dyadic, substance abuse- and treatment-related variables, as well as frequencies
of other male- and female-perpetrated aggressive dyadic behaviors. Higher frequencies of severe, but not minor, forms of FTM
psychological aggression uniquely predicted an increased risk of relapse at 6 months follow-up. These data add to the developing
research program highlighting the negative sequelae of female-perpetrated psychological aggression and also provide an empirical
basis for targeting specific dyadic behaviors in the context of SUD treatment and relapse prevention. 相似文献

This paper explores the link between increasing incidents of hate crime and the asylum policy of successive British governments
with its central emphasis on deterrence. The constant problematisation of asylum seekers in the media and political discourse
ensures that ‘anti-immigrant’ prejudice becomes mainstreamed as a common-sense response. The victims are not only the asylum
seekers hoping for a better life but democratic society itself with its inherent values of pluralism and tolerance debased
and destabilised. 相似文献
