The exploration, distributed as of late in PLOS One, found key components
identifying with untimely grown-up passings by examining dissection reports
and medico-legal demise examination records of 1,282 individuals between
the ages of 25 and 59 who kicked the bucket in Harris County in 2013. As
indicated by milestone research distributed in 2015, there has been a
sensational flood in the death pace of moderately aged white Americans since
1999. Untimely grown-up passings are characterized as passing before the
normal mortality age.

Raman spectroscopy is a logical method dependent on the actual marvel
of Raman dissipating, which models certain vivacious connections that happen
when photons crash into issue. SERS is a unique sort of Raman spectroscopy
that gives a "primary unique finger impression" of a material in any event,
when not many atoms are available in the objective example. Then again,
XRF examination includes lighting a material with X-beams and looking at the
energies of photons re-transmitted when the electrons in the example leave
the energized states. XRF investigation is particularly valuable to figure out
which metallic components are available in a material.

The biological diversity of vertebrates is uniquely significant to the concept of phylogeny. Phylogeny is a branch of evolutionary biology that
studies the evolutionary relationships between certain organisms. Reptiles and mammals are said to share the same evolutionary ancestry called
the amniotic-egged ancestor. This ancestor is divided into two groups; sauropsids (reptiles) and the synapsids (mammals). According to some
authors, the broadest group of the reptilian family is the sub-class Squamata. Examples of animals within this sub-class include, lizards, crocodiles,
snakes and amphisbaenians. However, man (Homo sapiens) belonging to the primate class, are the most intelligent and complex of all mammals.

Identification of victims is one of the most significant concerns while investigating the scene of occurrence but due to the delay in time of identification
it becomes difficult for the authorities to enable identification. The use of modern forensic techniques including the knowledge from disciplines like
forensic anthropology, toxicology, post blast residue analysts, forensic odontologists so as to speed up the investigation. The paper reviews the role
of a forensic anthropologist in the Disaster victim identification, on and off site. The use of radiographic techniques in order to know the biological
profile of the deceased as well to assist relocation in case of a fragmented body. In the current scenario, the forensic involvement of experts though
has been increased in identifying the victims, but still there needs to be more deployment at ground zero in order to increase proper investigation.
Disaster victim identification is a multidisciplinary approach and so collaboration from all the disciplines is needed so as to render justice.

Social life in India is enriched with festivals, traditions and cultural events, often, associated with bursting crackers during celebration. Firework exhibition and bursting crackers are a symbol of jubilation. The hazardous effects of fireworks are often obscured by the cloud of smoke and amusement ultimately breeding root cause to severe accidental injuries. Fire accidents occur due to surpassing supervisory measures while handling fireworks [1-3]. The illicit production, sale, illegal trade of crackers is another major direct challenge for criminal judiciary system and regulatory authorities [4-6]. Television, print and social media are crammed with evidences apart from actual incident data where crackers played a major role in crime. The chemistry of conventional fireworks has not much transmuted since archaic times. Common constituents in fireworks are carbon centered fuel, a reducing agent and an amalgamation of metal salts functioning as oxidant and colourants. The lightening of fireworks commences with an exothermic process engendering smoke as a by-product holding gases like carbon monoxide, carbon dioxide, sulphur dioxide and nitrogen dioxide, as well as suspended particulate matter between PM2.5-PM10. Conventional fireworks also integrate hazardous chemicals like nitrates of strontium, sodium and barium, carbonates of strontium, calcium, barium and copper, sulphates of strontium and calcium, chlorides of calcium and barium, aluminium and magnesium salts, sodium oxalate, copper oxide, iron dust powder and potassium perchlorate, which act as stabilizers, oxidizers and colorants [7]. Both metals and radicals determine the presence of explosive material. All these residues are hazardous in nature
