[Abbr: Acd. Jr. AJFSc]A Preliminary Study To Determine The Source Of Writer In Two Different Scripts Kannada And Telugu
by Kruthi V, Gayathri V.
Signature Analysis helps in identification of an individuals and is accepted under the court of law. Signature in India is found in various scripts based on this region. Kannada and Telugu are two prominent scripts of Southern India belonging to Karnataka, Telangana, and Andhra Pradesh. The current study aims at identifying the source of writer by comparing signatures made in Kannada and Telugu language. Handwriting characteristics are analysed and an opinion is framed based on the 50 Samples, Collected within the age group of 18-50 years. This approach provides an insight into the examination of multi-lingual scripts and helps in understanding the importance of scripts in Signature Analysis.

A Preliminary Study on Kannada Handwriting Characteristics Amongst Karnataka Population
by Gayathri V., Dr. Manjula
Handwriting examination is one of the key types of evidence in solving both criminal and civil cases. India is known for its diverse languages with vast scripts across the country. One among the languages is Kannada which is mother language of the state Karnataka with 49 letters and 10 vowels. The study aims to determine the natural variations in Kannada writings by analysing the handwriting characteristics such as letter formations, spacing, pen pressure, slant, and rhythm. A total of 50 samples were collected within the age group of 18-25 from both male and female. A set of 3 writings were collected in different speeds to understand the factor affecting the handwriting. This study sheds light on fostering the differences and similarities in Kannada writings in determining the source of the writing. The study aims at bridging the gap in analysing handwriting by understanding the relationship between language and educational background of individuals. Keywords: Handwriting, Linguistic, Kannada, Natural Variations, handwriting Characteristics.
Introduction of Forensic Science in BSc Nursing: A Paradigm Shift in Indian Healthcare
by Jaspinder Pratap Singh, Dr. Sunny Basra, Dr. Ashok Chanana, Dr. Yatin Talwar
Forensic science, the interface of legal and scientific knowledge, has emerged as a required branch in today's healthcare. The inclusion of forensic science in BSc nursing courses in India has gained pace in the past few years, providing a golden opportunity to fill the gap between healthcare and law. This review article discusses the introduction of forensic science or forensic medicine in Indian BSc nursing courses and its possible impact on nursing practice, patient care, and the healthcare system. India can solve significant issues like medico-legal cases, violence against women, child abuse, and deaths under suspicious circumstances and improve the quality of healthcare delivery by imparting forensic training to nurses. Keywords: Forensic science, medico-legal cases, healthcare system.
Development of Aged Latent Fingerprints from Non-Porous Surfaces using Molybdenum Disulphide
by Mohammed Suhail, Gayathri V.
Molybdenum disulfide (MoS₂) is one of the most commonly utilized small particle reagents (SPR) for revealing latent fingerprints on wet, non-porous surfaces like glass, metal, steel, aluminum, and plastic. Its high surface concentration, lubricating properties, and strong adhesive qualities with fingerprint residues give MoS₂ a distinct advantage over surfaces that are typically too slippery or reflective to yield results with traditional fingerprint powders. This study focused on developing latent fingerprints from various non-porous surfaces that had been submerged in water. Samples were collected from these surfaces and exposed to environmental conditions. A total of 15 samples were collected to assess the effectiveness of MoS₂ over different time intervals. The objective was to evaluate the performance of MoS₂ in revealing aged fingerprints. Keywords: MoS2, Fingerprint, Non-Porous Surfaces, Ageing Studies, Latent Prints.
Cyberpsychology in Forensic Science
by Sanskriti Rani Sharma
Cyberpsychology is the study of psychological processes related to all aspects of technologically interconnected human behavior. In other words, it can be described as the psychology of cyberspace, focusing on the intersection of technology and human behavior. This field explores the differences in human behavior between offline and online interactions, revealing both the positive and negative impacts of online platforms on individuals. Furthermore, we see a connection to forensic aspects, as modern crimes often utilize advanced digital methods for both committing offenses and evading capture. The online world creates a virtual reality tightly woven into social media platforms. Our lives increasingly revolve around these platforms, including Instagram, Twitter, WhatsApp, Facebook, and many others. In this discussion, we will examine cyber cases and how cyberpsychology is applied in these contexts. We will also explore e-therapy, also known as online counseling, which provides therapeutic services to patients over the Internet. However, it is essential to consider not only the positive aspects but also the ethical and legal issues surrounding this area, as it remains controversial. Many misconceptions about cyberpsychology persist, given that psychology is not always openly discussed, despite the advancements we've made in this digital era. We will investigate the new methods and techniques incorporated into cyberpsychology. Keywords: Cyberpsychology, Human Behavior, Social Media Platforms, Digital Era.
The Impact of Protein Biomarkers on Time Since Death Estimation Using Diverse Molecular Techniques
by Bhumit Chavda, Dr. Kapil Kumar, Dr. Saumil Merchant
The estimation of time since death (TSD) is a critical component of forensic science, aiding in criminal investigations and legal proceedings. Accurate estimation involves considering factors such as Algor Mortis, Rigor Mortis, Lividity (Livor Mortis), chemical changes, metabolic processes, RNA, DNA, protein degradation, and radiological imaging systems. This study explores the role of biomarkers, specifically proteins, in determining TSD through various analytical techniques applied to human and animal tissues. As decomposition progresses post-mortem, specific biochemical changes occur, allowing for the identification of reliable biomarkers. Certain biochemical alterations take place as post-mortem decomposition advances, making it possible to identify trustworthy biomarkers. We examine well-known techniques such as Immuno-histochemical (IHC), ATR-FTIR, Mass spectrometry, liquid chromatography, Western blotting, and enzyme-linked immunosorbent assay (ELISA), emphasizing how well they measure the composition and degradation of proteins. We show how the identification of protein biomarkers can improve the precision of PMI estimates by combining various methods. Biomarkers and protein estimation techniques are invaluable in forensic science for estimating the time since death. By concluding, we can understand the biochemical changes that occur post-mortem and by employing advanced analytical techniques, forensic scientists can provide more accurate TSD assessments, aiding investigations and legal proceedings. The different techniques were used widely in which SDS-PAGE, Gel Electrophoresis, and Western Blot were used mostly due to their precise estimation of protein level.
