Abstract: Ricin is a glycoprotein from Ricinus communis seeds. It is known to have diverse toxic effects on cells of different visceral organs. In the present study, we purified and denatured ricin in a boiling water bath for different time intervals. We further made an attempt to identify native and denatured ricin by immunobased detection systems. All the antigen/antibody‐based assays identified native and denatured ricin. On SDS–PAGE, only native ricin was observed. In western blotting, ricin boiled for 3.75 min gave a strong band on X‐ray film. On native polyacryl amide gel electrophoresis, native and denatured ricin gave ricin band in 60‐kDa region. The denatured ricin did cause mortality up to 25 mg/kg, while 5 and 10 μg/kg of native ricin caused 50% and 100% mortality, respectively. Detection of native and denatured ricin is very difficult, and the investigating agencies, forensic scientists, and analysts should be very careful while interpreting the results. 相似文献
Abstract: In estimating the postmortem interval (PMI) using maggots obtained during autopsy, the forensic entomologist makes decisions regarding the effects of low‐temperature storage of the body on the insects. In this case report, a corpse was found in an abandoned house in the residential area of Bukit Mertajam, Penang, Malaysia. The maggots were found to be alive inside the mouth of the deceased although the corpse had been in the morgue cooler for 12 days. The maggots were reared and identified as Chrysomya megacephala (Fabricius). The emerged adult flies were kept as a stock colony, and the duration of development under the indoor fluctuating temperature regime was studied. The total duration of developmental process of this species was 9.5 ± 0.5 days, and the PMI estimated was 3.2 ± 0.6 days. This case report demonstrates the survival of Ch. megacephala maggots for 12 days and their growth inside the morgue cooler. 相似文献
In an air‐conditioning system, the compressor is a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. The explosion of an air conditioner (AC) compressor is an uncommon event, and immediate death resulted from the blast effect is not reported in forensic literature. We report three such cases in which young AC mechanics were killed on the spot due to compressor blast, while repairing the domestic split AC unit. The autopsy findings, the circumstances leading to the explosion of the compressor, are discussed in this study. 相似文献
In some Latin American nations, policy change occurs frequently, while in others it is stable, less prone to shifts with the prevailing political climate or shocks. The conditions under which institutional rules and the powers of key actors influence the capacity for governance vary, and this variation is seldom addressed in the literature. This project examines the effects of the interactions between key policymakers (the executive and the legislature) in Latin America on policy stability across different institutional frameworks. Countries with simultaneously strong executives and weak legislatures are shown to have unstable policy environments, as are countries with a history of unified government and, to a lesser extent, candidate‐centered electoral systems. 相似文献
It is good to take stock from time to time and to see how things stand in jurisprudence. So, what is the relationship of doctrine and theory with jurisprudence? Is private law theory apolitical while public law contains politics for the very many constitutional ends in the Global South? In India, legal theorist Chhatrapati Singh very originally asked if legal systems and normative systems were the same? Chhatrapati’s enquiry was however a species of the classical approach to the law that promotes the law’s purity. On the contrary, the postcolonial approaches account for the historical life as well as the political proclivities of the law. The private law theory often seen as impersonal and non-imperial comes under scrutiny in the postcolonial approaches. Duncan Kennedy and Roberto Unger notably problematized contract theory, while Upendra Baxi argued for mass tort as public law—contract and tort are both private law—to offer, if you will, a jurisprudence of the South. A southern jurisprudence essentially rejects an impersonal reading of the private law.
The paper argues for conflating refugees and internally displaced persons (IDPs) as two sides of a work-in-progress postcolonial state. To be sure, aliens, refugees, IDPs, and stateless persons are separate legal entities. Nevertheless, this fragmented normative regime stands testimony to more laws and less justice. Many Asian states have no domestic refugee law. India, a common law system, takes a case by case approach as refugees are given “temporary shelter on humanitarian considerations”. Ironically, a work-in-progress postcolonial state sustains even de jure citizens as de facto stateless persons; the erstwhile Indo-Bangla enclaves for more than half a century were an apt example. Surely, the raison d’être of international law on refugees is to end human suffering, if needed, by transcending the absence of positive laws. A constitutional and political desire to minimise human suffering alone could cut the rigour of such positivist legal narratives. The Delhi High Court seemingly walked that path in Koul v Estate Officer noting “refugees and IDPs appear to be similarly situated”. Rising terrorism has made states increasingly believe in a security narrative all the same. A simultaneous emergence of a demographic anxiety particularly in India’s North-eastern states increasingly pits aliens and refugees against the domiciled indigenous and tribal people. 相似文献

Insect faunal succession on decaying rabbit carcasses was carried out at Punjabi University, Patiala (Punjab), India, from March 1997 to December 1999. Four stages of decomposition were recognized, i.e., fresh, bloated, decay, and dry. A total of 38 insect species belonging to four orders and 13 families were recorded. Diptera, Coleoptera, and Hymenoptera dominated the carrion fauna. Calliphorids were the first to arrive in all the seasons of the year. Five species of Calliphoridae, four of Sarcophagidae, ten of Muscidae, and one each from Anthomyiidae and Otitidae were observed on rabbit carcasses. Representatives of six Coleopteran families, i.e., Staphylinidae, Histeridae, Cleridae, Dermestidae, Tenebrionidae, and Silphidae, were recorded. Eight species belonging to family Formicidae (Hymenoptera) were also collected during the present studies. Only one species of Lepidoptera was observed on carrion. 相似文献
