In early 1947, American intelligence organisations learned that there were hidden collections of technical documentation that pertained to World War II German guided weapon development that were not recovered by Allied investigators in 1945. A joint Anglo-American intelligence operation was initiated in February of that year, dubbed ‘Project Abstract’ by the Americans, to recover the caches. Project Abstract was a concerted effort by British and American scientific and technical intelligence experts to round up the last material remains of the World War II guided weapon programmes at the renowned experimental and testing establishments at Peenemünde in northern Germany. 相似文献

Abstract: Electronic control devices (including the Advanced TASER® X26 model produced by TASER International) incapacitate individuals by causing muscle contractions. To provide information relevant to development of future potential devices, effects of monophasic square waves with different parameters were compared with those of the X26 electronic control device, using two animal models (frogs and swine). Pulse power, electrical pulse charge, pulse duration, and pulse repetition frequency affected muscle contraction. There was no difference in the charge required, between the square waveform and the X26 waveform, to cause approximately the same muscle‐contraction response (in terms of the strength‐duration curve). Thus, on the basis of these initial studies, the detailed shape of a waveform may not be important in terms of generating electro‐muscular incapacitation. More detailed studies, however, may be required to thoroughly test all potential waveforms to be considered for future use in ECDs. 相似文献

Detailed comparison of factors associated with abnormal approach to the prominent and with escalation from communication to approach has not hitherto been undertaken. This partially reflects the failure of individual studies to adopt compatible terminologies. This study involves a careful dissection of six public figure studies, three involving U.S. politicians, two Hollywood celebrities, and one the British Royal Family. Common findings were unearthed across six headings. Approachers were significantly more likely to exhibit serious mental illness, engage in multiple means of communication, involve multiple contacts/targets, and to incorporate into their communication requests for help. They were significantly less likely to use threatening or antagonistic language in their communications, except in those cases involving security breaches. These results emphasize the importance of integrating mental health findings and preventive measures into risk management. Approach should not be regarded as a single behavioral category and has multiple motivations. Future studies should adopt standard terminology, preferably taken from the general stalking research. 相似文献

Religious faith has always had an intense but uneasy relationship with development. Donors are currently seeking greater engagement with faith-based organisations (FBOs). This positive shift needs careful consideration. Faith can be a powerful – but flammable – fuel for change. FBOs are highly diverse and complex. Donors therefore need to handle them with understanding and care. This article outlines both the major concerns about faith in development and also the potential ‘value-added’ of FBOs. It charts growing interest yet residual ambivalence on the part of donors towards faith in development. It presents the practical challenges and suggests ways forward for both donors and FBOs. 相似文献

Electronic control devices (ECDs) may eventually be deployed by the military in a manner resulting in longer exposures than those encountered during law-enforcement operations. In a previous study, 18 repeated cycling (5-second on/5-second off) exposures (within a 3-minute period) of anesthetized swine to an ECD (TASER International's Advanced TASER X26 device) resulted in leg muscle contraction, acidosis, and increases in blood electrolytes. In the current study, experiments were performed to examine effects of exposures to a different cycling rate (7-second on/3-second off), from a modified X26 ECD, on 10 swine (Sus scrofa), maintained on propofol anesthesia. In contrast with the previous study, a large number of animals (6/10) died immediately after the exposures. There were no major differences in pre-exposure blood factors from survivors versus nonsurvivors, with the exception of hematocrit and 2 isoenzymes of lactate dehydrogenase. It is doubtful that these factors would be useful in predicting survival after ECD exposure. Blood pH was significantly decreased after exposure, but (in animals that survived) subsequently returned to baseline levels. On the basis of the overall survival rate, further development of useful ECDs (for long-term incapacitation during military operations) may require consideration of longer pauses between repeated exposures over a 3-minute period. 相似文献

Is Google in its quest for search engine optimization through the creation of new technologies, which not only improves its search algorithms but also refines its search functions for users, doing it in a manner that makes it a perpetrator of primary copyright infringement or an invaluable facilitator for Internet functionality? How should the balance of interests in the treatment of creative works be recalibrated in the face of changes in search engine technology and operations, and the disputes that have arisen within the last decade in the context of the digital age and its needs? Using Google as a case study, this paper will look at the two main areas of dispute over the operations of information locator tools and services that either threatens search engine functionality and efficiency or weakens copyright holders’ exclusive rights. It proposes a concerted set of solutions through a reassessment and amendment of copyright law to optimize the social benefits and objectives of both the copyright regime and technological innovations in the electronic model of information archiving, indexing and delivery. A fair distribution of responsibilities and allocation of rights and liabilities will be suggested. In the process, due consideration will be given to both public and private interests, with the former taking precedence; while the recommended solutions will be made within the currently outdated framework for Internet intermediary protection (i.e. safe harbor laws) and exceptions (i.e. specific statutory exemptions and the general fair use defense) under the existing copyright regime. Thus, the proposed changes will be far reaching without being too radical a departure from current law, an evolution that will likely be more acceptable and realistic a solution to the problem.This paper is published in two parts. Part One of this paper will deal with the challenges to the copyright regime posed by the operations and technology behind the Google Images Search Engine, while Part Two that will be published in the subsequent edition of the CLSR will assess the benefits of the Google Books Search Project vis-à-vis the effects it will have on the scope of copyright protection. Recommendations are made to copyright law to accommodate both functions while generally preserving the main objectives of copyright protection. 相似文献

The effect of dose-death interval and tissue distribution on the detection of meperidine in selected skeletal tissues was examined using a rapid microwave-assisted extraction (MAE) methodology. Rats (n=14) were dosed with 0 (n=2) or 30 mg/kg (n=12) meperidine (i.p.). Drug-positive rats were sacrificed with CO(2) after 20, 30, 90 and 150 min (n=3 per group). Heart blood was collected immediately after death. Tibiae were excised and frozen for further analysis. The remaining carcasses were allowed to decompose outside in secured cages to the point of complete skeletonization in a rural Northern Ontario location during the late summer months. Vertebrae and pelvi were collected for each animal. Tibial marrow was homogenized in 3 mL PB6 (phosphate buffer, 0.1M, pH 6). Fresh tibiae, and decomposed vertebrae and pelvi were cleaned in PB8.5 (phosphate buffer, 0.1M, pH 8.5) and sonicated to remove remaining soft tissue. Samples of dried, ground bone (0.5-1g) suspended in 2 mL PB6 were then irradiated in a domestic microwave oven (1100 W) at atmospheric pressure for 15 min. Samples of vertebral bone (1g) were also extracted by passive incubation in methanol (3 mL, 50°C, 72 h). All supernatants then underwent solid-phase extraction and analysis by GC/MS, using electron impact ionization in the Selected Ion Monitoring (SIM) mode. Mean GC/MS responses for each tissue type were negatively correlated with dose-death interval, with correlation coefficients ranging from -0.32 to -0.87. Analysis of variance showed dose-death interval to be a main effect (p<0.05) with respect to GC/MS response for blood, marrow, tibial epiphyses prepared by MAE, and vertebral bone prepared by passive extraction, but not for tibial diaphyses, pelvi or vertebrae prepared by MAE. Overall, MAE is advantageous as a rapid extraction tool for screening purposes in skeletal tissues, but assignment of significance to quantitative expressions of skeletal drug concentrations is complex and should be approached with caution. 相似文献
