In almost every criminal investigation, it is necessary to establish whether a particular person or persons may or may have not been present at the scene of a crime. In this regard, the application of forensic science plays a vital role in the criminal investigation to establish the identity of the offender. Like a fingerprint, the footprint of every person is unique and can be used to identify a person. It can help to link the suspect to a crime scene and the victim. Every individual's print contains friction ridges and other individual characteristics that are unique to that person. The present study aims to identify, analyze, and illustrate the individual characteristics of footprints of the tribal population in Jhargram District, West Bengal, India from a forensic perspective in a sample of 120 adult tribal people participants consisting of 60 males and 60 females. These tribal people live in deep forest areas and most of the people walk barefoot day by day. The footprints were collected using a footprint ink slab and white paper. Various identification characteristics feature were identified and recorded during analyses of the collected footprint from different parts of the foot, like, the number of toes, number of humps, phalanges marks, corn, pits, cracks, Crease marks, etc.

The West African country called Niger is blessed with seven neighbouring countries which surrounded all its frontiers in spite of the fact that it is a landlocked country with no direct access to the sea. The rich natural resources like uranium attracted several Multinational Corporations (MNCs) to set up for the Exploration, Expropriation and Exploitation (3Es). Yet, the country remains one of the poorest and under developed for 63 years after independence but was crowned in the position of Heavily Indebted Poor Country Initiatives (HIPC). Unfortunately for France as the main consumer of Niger’s resources through the use of pro-French leaders of the country, the 21st Century was not going to be the same as it recently happened in the previous four decades of the 20th Century. To that effect, a New Generation of West African Leaders (NGWAL) from Mali, Burkina-Faso and Mali individual decided to take the bull by the horns with main objective to overthrow Purported Pro- French Civilian Leaders (PPFCL) in order to end all the mechanisms and networks of neo-colonialism as impediments to National Development and Unity (NDU) which in turns fuelled periods of social unrest and political instabilities since the 1960s. Therefore, Niger was not left out in this neo-colonial dance of the third decade of the 21st Century as it happened in 2023 with strong sentimental feelings in favour of the suffering Nigeriens. The scrutinized of specialized sources of information enable us to use a historical approach with our findings that Niger is on good footing towards new structural developmental agenda without any single dictatorial prescriptions from the neo-colonial men of Western Europe.

Background: Hypertensive disorders of pregnancy are a significant contributor to maternal mortality, with early identification of risk factors being crucial for proactive management. This study explores the potential of mid-trimester maternal serum β HCG levels as a predictive marker for hypertensive disorders during pregnancy. Objective: The primary objective of this prospective study was to evaluate the clinical utility of second-trimester serum β HCG levels in predicting the development of hypertensive disorders during pregnancy. Methods: The study, conducted from June 2020 to July 2021, recruited pregnant women aged 13-20 weeks who were normotensive and non-proteinuric. Data from 100 respondents were collected, with 50 in each group (Group A with β HCG > 35000 m IU/ml and Group B with β HCG < 35000 m IU/ml). Statistical analysis was performed using SPSS 24.0, and the significance level was set at p < 0.05. Results: Group A had a significantly higher proportion of hypertensive disorders compared to Group B (38% vs. 10%, p < 0.001), with Group A being more than five times as likely to develop hypertensive disorders (cOR = 5.5, 95% CI: 1.862, 16.344). Serum β HCG levels in respondents with hypertensive disorders (Mean = 60626.88 m IU/ml) were significantly higher than those who were normotensive (Mean = 32812.18 m IU/ml, p < 0.001). Sensitivity was 79.17%, specificity was 59.21%, and positive and negative predictive values were 38% and 90%, respectively. Conclusions: Mid-trimester serum β HCG levels are an efficient non-invasive predictor of hypertensive disorders during pregnancy. With its high sensitivity and negative predictive value, this cost-effective test can aid in the early identification and proactive management of at-risk pregnancies.

Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when bilateral posterior segment of teeth is missing.

The purpose of this article was to describe a case of a patient with extended Kennedy's class I condition, which was prosthetically restored by a combined prosthesis using a extracoronal precision attachment.

With the rising trend in obesity, the incidence of gestational diabetes mellitus (GDM) and perinatal complications associated with the condition are also on the rise. Since the early 1900s, much knowledge has been gained about the diagnosis, implications, and management of gestational diabetes with improved outcomes for the mother and fetus. Worldwide, there is variation in the definition of GDM, methods to screen for the condition, and management options. The International Association of Diabetes in Pregnancy Study Groups has published recommendations for a one-step approach to screen pregnant women for GDM, in order to develop outcome-based criteria that can be used internationally. However, management of GDM continues to be varied, and currently several options are available for treatment of hyperglycemia during pregnancy. A review of various aspects of GDM is discussed with a focus on the medical management during pregnancy, as practiced in the United States.

The study investigates the effect of convective flow on entropy generation for MHD heat transfer flow of viscous fluid embedded in a porous channel due to thermal radiation. The governing equations were transformed using the non-dimensional parameters. The solution of the resulting coupled dimensionless differential equations with a constant coefficient describing the momentum, energy, and mass transfer equations was obtained by using the method of undetermine coefficient. The parameters embedded in the flow are thermal radiation , Prandtl number, entropy generation , Suction/injection parameter , heat source/sink , porous material . In addition, physical quantities of engineering interest such as the Bejan number , Brinkman number , volumetric flow rate , skin friction coefficient, and heat transfer rate were computed.
