Thermodynamic Irreversibility in Semen Transport
Abstract: Sperm ejaculation is a vital reproductive process that involves both complex biological functions and energetic mechanisms. Beyond the physiological aspects, thermodynamics offers a framework to analyze energy conversion, exergy use, and irreversibility during sperm activity. ATP provides the main source of exergy for motility, but part of this energy is inevitably lost as heat and entropy generation, reflecting inefficiencies in the process. Because heat regulation directly affects metabolic rates, motility …

Basic Urea and Ammonia Synthesis
Abstract: AbstractIndian population has continued to grow at the rate of 1.2% per year. This population explosion demands for around 263 million tonne of food grain per annum. From the present level of production of some 241 million tonnes (2012–2013); it is clear that an adequate quantity of fertilizer has to be made available. Urea (NH2CONH2) and ammonia (NH3) are of great importance to the agriculture industry as nitrogen-rich fertilizer. This …

Historical Antecedents of Boko Haram Insurgency and Its Implications on Educational Development in Northeast Nigeria
Abstract: The Boko Haram insurgency has greatly affected the socio-economic and educational systems of Northeast Nigeria. This paper examines the historical antecedents of the insurgency, analyzing how socio-political, economic, and ideological factors have contributed to its emergence and persistence. The study highlights the enduring impact of colonial legacies, socio-economic marginalization, and governance failures, which have collectively created fertile ground for the radicalization of disenfranchised populations. The insurgency’s deliberate targeting of educational …

A Study on the Influence of Cashew and Pawpaw Leaf on Soil Density Treatment of Contaminated Swampy and Clay Soils
Abstract: Soil density is a key parameter in assessing soil health and structure, often employed as a potential index in bioremediation studies. This study investigates the impact of bioremediation treatments using Cashew Leaf (Anacardium occidentale) and Pawpaw Leaf (Carica papaya) on the density of swampy and clay soils over time. The results show that both treatments, in varying quantities, influence the soil's density by reducing the post-contamination density to levels closer …

A Comprehensive Review on Male Infertility
Abstract: The failure to attain a clinical pregnancy naturally after one year of unprotected intercourse is termed as infertility. Some of the factors that contribute to Infertility are late marriages, advanced age, genetics and lifestyle to name a few. To tackle this scenario, infertile and sub fertile couples take the aid of assisted reproductive technology. Intra uterine insemination (IUI), In vitro fertilization (IVF), Intra cytoplasmic sperm injection (ICSI), surgical sperm retrieval …

Challenges & Issues in Natural Gas Distribution Industry
Abstract: Natural Gas Distribution or City Gas Distribution (CGD) in India is at a nascent stage. Before the establishment of Petroleum and Natural Gas Regulatory Board (PNGRB), the sector was unstructured and direction-less at times. With the formation of PNGRB, the safety practices of CGD business were looked into and guidelines were framed. However, the initial legal disputes within PNGRB retarded the growth. The first three bidding rounds in the sector …
