A GC/MS-method is described for the screening, detection and determination of the commonly used drugs amphetamine, methamphetamine, MDA, MDMA and MBDB in small blood samples and bloodstains using solid phase SPE columns and a pipetting robot (Gilson Aspec XL). The detection limits are in the order of 0.03 to 0.08 microgram/L and the correlation factors between 0.9982 and 0.9998. Furthermore the stability was investigated covering a storage time of 64 days. The method has proven useful in forensic cases with only small sample volumes or bloodstains.  相似文献

The surface of different types of garbage bags was scanned using non-contact laser profilometry. Manufacturing defects known from visual inspection of the bags (fish eyes, arrowheads, and surface scratches) appear as differences in the height profile. Extrusion lines could only be detected in low-density polyethylene bags. Their correlation length is a couple of centimeters, whereas visually they continue over meters. This can be used to link together the end of one garbage bag with the beginning of the subsequent bag. Extrusion lines are of the order of 0.1 microm for high-density polyethylene garbage bags.  相似文献

Routine STR-typing of 10,293 buccal swabs using different multiplex kits presented discordant D8S1179 profiles in four cases. Sequencing analysis identified a G-to-A transition upstream to the repeat, and an A-to-T transversion and a G-to-A transition downstream to the repeat. In the fourth case a four-base pair deletion downstream resulted in altered genotypes using different primer pairs. Current searching algorithms of the German DNA database are not capable of matching profiles that are divergent in only one STR-locus. Thus, to accommodate matching requirements and to avoid errors in individual genetic characterization for D8S1179, as described here, it is suggested that alternative primer pairs be used for routine genotyping as a matter of course.  相似文献

A 66-year-old man received a local infiltration of cortisone and xylocain in the left paravertebral region between the fifth and sixth cervical vertebrae. Respiratory failure occurred 2.5 h later with subsequent successful resuscitation. During the following 2 months of assisted ventilation up to the patients death, tetraplegia with concurrent full consciousness throughout was observed. Magnetic resonance imaging confirmed an ischaemic lesion of the upper anterior cervical myelon. The forensic autopsy revealed pneumonia as cause of death. Neuropathology confirmed anterior infarction at the C2/C3 level of the cervical myelon, with obstruction of the anterior spinal artery by an epithelialised fibrocartilaginous embolus. The autoptic findings suggest that this embolus stems from the site of previous analgetic infiltration, with accidental laceration of an intervertebral disc and subsequent transportation of discous material via injection canula into an artery.  相似文献

This paper is devoted to theoretical and methodical considerations on our study and understanding of macroscopic transitions in the world of Sanskrit intellectuals from the sixteenth to the eighteenth century (cf. Pollock, Indian Economic and Social History Review 38(1):3–31, 2001). It is argued that compared to his immediate predecessors Bha??oji Dīk?ita’s contribution to Prakriyā grammars was modest. It was to a large extent on account of changed circumstances—over the centuries mainly a slow but steady decline—in the position of Sanskrit and the general public’s need for a simple definition of authoritatively correct Sanskrit that Bha??oji’s grammar met with success so quickly, so widely, and so solidly. I once knew a little boy in England who asked his father, “Do fathers always know more than sons?” and the father said “Yes.” The next question was, “Daddy, who invented the steam engine?” and the father said “James Watt.” And then the son came back with “But why didn’t James Watt’s father invent it?” Gregory Bateson (1972, p. 21)   相似文献

Potential of the state to control privatized firms   总被引:1,自引:0,他引:1  
The privatization strategy in many transition economies involved the creation of a special government agency that administered state property during privatization programs as well as after the privatization was declared complete. The National Property Fund (NPF) was the agency in the Czech Republic. In many firms the state kept property long after the privatization was completed. We analyze the control potential of the state exercised through the NPF via the control rights associated with capital stakes in firms along with special voting rights provided by law. Based on a complete data set on assets as well as the means of control in privatized firms we conclude that for most of the 1994–2005 period, the state control potential was extensive and certainly larger than has been found by earlier research.

A case of suspected acute and lethal intoxication caused by colchicine has been reported. The woman was hospitalized after her suspicion of suicidal poisoning by a rare autumn crocus (Colchicum autumnale). Suspected colchicine poisoning was confirmed using a novel UHPLC method with a modern reversed‐phase stationary phase with a sub 2‐micron superficial porous particle size combined with a QTOF mass spectrometer. Sample preparation procedure included the addition of propiverine as internal standard, protein precipitation using methanol and solid phase extraction. High‐resolution MS only and targeted MS/MS modes are reported for the qualitative analysis and screening of other potential drugs of abuse in blood samples. All Ion MS mode was used for quantitative determination of colchicine afterward. The concentration of colchicine in the blood sample was approximately 41 ng/mL, and more than 200 μg/mL of the plant extract used for the suicide.  相似文献

Madhyamaka philosophy has been frequently characterized as nihilism, not just by its Buddhist and non-Buddhist opponents, but also by some contemporary Buddhologists. This characterization might well strike us as surprising. First, nihilism appears to be straightforwardly inconsistent (“if there is nothing, there is still the fact that there is nothing, so there is something”). It would be curious if a philosophical school holding such an obviously deficient view would have acquired the kind of importance Madhyamaka has acquired in the Asian intellectual landscape over the last two millenia. Second, Madhyamaka by its very name proclaims to tread the “middle way”, and what if anything would count as an extreme position but the view that there is nothing? This essay addresses both the systematic status of nihilist theories as well as the historical contexts in which Madhyamaka has been characterized as nihilistic, aiming to throw some light on plausible and implausible ways of understanding the Madhyamaka intellectual enterprise.  相似文献
