Fingerprints are unique and can be used to identify individuals. They are comprised of ridges and valleys that form distinctive patterns classified as loops, whorls, or arches. Fingerprint identification involves comparing ridge characteristics like ending ridges, bifurcations, and dots between two prints and looking for multiple matching characteristics in the same relative positions to determine a match. While some countries have a set number of ridge characteristics required for identification, examiners in the US can use their experience and discretion to decide based on print clarity and uniqueness.
A fingerprint is an impression of the friction ridges on all parts of the finger. A friction ridge is a raised portion of the epidermis on the palmar (palm) or digits (fingers and toes) or plantar (sole) skin, consisting of one or more connected ridge units of friction ridge skin. These are sometimes known as "epidermal ridges" which are caused by the underlying interface between the dermal papillae of the dermis and the interpapillary (rete) pegs of the epidermis. These epidermal ridges serve to amplify vibrations triggered when fingertips brush across an uneven surface, better transmitting the signals to sensory nerves involved in fine texture perception. The ridges do not assist in gripping objects, sometimes in fact reducing grip to as much as 30% compared to completely smooth fingerpads.

Fingerprints are an impression or mark made on a surface by a person's fingertip, able to be used for identifying individuals from the unique pattern of whorls and lines on the fingertips. These are one of the most important evidences found on the scene of crime and if processed carefully can help to identify and individualize the culprit within short time...
Portrait Parle via Bertillon System By G S ShaktawatG.S Shaktawat
The individualization of the human is very hard thing from the ages. People had done or invented certain ways for the proper individualization of the person. The Bertillon System is the first anthropological technique for individualization invented by Sir Bertillon.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

9. WHY FINGERPRINTS? Fingerprint evidence is the most positive investigative means for identifying people. Fingerprints form on a person before birth and remain unchanged until the body decomposes after death. Every fingerprint is unique!
10. WHAT IS A FINGERPRINT? A fingerprint is a pattern of friction ridge details, that are comprised of ridges and valleys. A Ridge – is a high. A Valley – is a depression or low. Friction ridges are also found on our palms, feet and toes.
12. THE PATTERN The pattern is the unique characteristics of the ridges and valleys that make up the print. It is defined by the spatial relationship of lines with each other, their beginning and terminating points, and the unique pattern they make. The genes from our parents determine the general characteristics of the patterns.
13. FINGERPRINT IDENTIFICATION 1. What are fingerprints? Recorded impressions of the friction ridges located on the surface of the finger. 2. What is the purpose of fingerprint identification? To establish the identity or non-identity of two sets of fingerprints.
14. FINGERPRINT IDENTIFICATION 3. What are fingerprint characteristics? These are also known as ridge detail, points of identification, or identifying characteristics. Ending Ridges Bifurcations Dots Enclosures Short Ridges
15. FINGERPRINT IDENTIFICATION 4. How are fingerprints compared? Fingerprints are compared by noting the ridge characteristics on two prints to determine whether or not they match. An identification is established when a number of these characteristics occupy the same relative position on the two prints.
16. FINGERPRINT IDENTIFICATION How many points of identification (characteristics) are sufficient to establish an identification? A. No set standard number required. B. Left to each individual fingerprint examiner. C. Deciding factors: 1. Clarity of impressions 2. Uniqueness of formations Fingerprint examiners experience and ability
18. FINGERPRINT IDENTIFICATION Be extremely cautious! The integrity of the identification process depends on the fingerprint examiner devoting his or her attention to comparison work at all times. Always be certain that the fingerprints have been printed in the proper finger blocks. Be absolutely certain of your decision NOTE: As many as 150 ridge characteristic can be noted in the average fingerprint.
