Diatoms are unique algae. They are scientifically known as Bacillariophyceae. Diatoms have been used in forensic science in a variety of ways, the most frequent being the diagnosis of death by drowning. When a person drowns, water will enter the lungs and then enter the bloodstream through ruptures in the peripheral alveoli before being carried to the other organs such as the liver and heart. Naturally, the microscopic contents of the water, which will include diatoms, will pass into the blood as well. The detection of diatoms in the organs can contribute to a diagnosis of death by drowning, a process referred to as the ‘diatom test’. A study was conducted in the department of Forensic Science, SHUATS, Prayagraj which included the extraction and identification of diatoms from the collected water samples from three different sites of Kaalesar Ghat of Rapti River in Gorakhpur. The acid digestion method was used for diatom extraction. And, after analysis total 13 diatom species were found. The identified diatoms were of great ecological assessment that plays an important role in criminal investigations related to pre-mortem or ante-mortem drowning.

One of the good indicators of social control of power is the way in which contemporary societies deal with transitional justice. The most academic approaches to transitional justice, especially in Brazil, usually does not observe the role played by The Supreme Court in particular, and the judiciary in general. This paper seeks to make a relatively different approach. We observe the regulatory frameworks of the Brazilian authoritarian periods, such as the preamble of the 1937 Brazilian Constitution and the preamble of the Institutional Act n. 1/64, looking at them as they were like the Comic Code Authority, in a comparative approach, and observing, also in a comparative way, the Supreme Court as representative of a kind of “Ring of Gyges”, the mythical famous magical artifact mentioned by Plato in his Republic, in order to allow the “invisibility” of supposed heroes at authoritarian regimes, in a struggle that sought to identify “good guys” and “bad guys”, or the “good” versus “evil” in a context in which normative transitional disputes resemble reports of different narratives, and within which the version matters more than the responsibility for the violation of rights and the human dignity. This paper uses the essay style, through bibliographic review as a method to talk about the theme described in this abstract.
