This study employed Fourier Transform Infrared Spectroscopy (FTIR) to evaluate the chemical composition of the aqueous leaf extract of Artemisia annua, a plant recognized for its medicinal properties. Conducted at Joseph Sarwuan Tarka University and the University of Ibadan, Nigeria, leaves were collected, authenticated, and processed through soaking in sterile distilled water and methanol. FTIR analysis identified several key functional groups, including a hydroxyl group at 1028.75 cm ¹ (indicating alcohols), an alkene at 1073.47 cm ¹ (suggesting diethyl ether), nitriles at 1267.29 cm ¹...

The increasing reliance on borehole water as a primary source of drinking water across Africa raises significant concerns regarding its quality and safety. This book assesses the physicochemical characteristics and hardness status of borehole water in various regions of Africa, focusing on its implications for public health. Water samples were collected from multiple boreholes, and key parameters such as total hardness, pH, turbidity, electrical conductivity, and concentrations of essential minerals (calcium, magnesium) were analyzed. Preliminary findings indicate that while some samples fall...

In dieser Studie wurde die Fourier-Transform-Infrarot-Spektroskopie (FTIR) eingesetzt, um die chemische Zusammensetzung des wässrigen Blattextrakts von Artemisia annua, einer für ihre medizinischen Eigenschaften bekannten Pflanze, zu bewerten. An der Joseph Sarwuan Tarka University und der University of Ibadan, Nigeria, wurden die Blätter gesammelt, authentifiziert und durch Einweichen in sterilem destilliertem Wasser und Methanol verarbeitet. Bei der FTIR-Analyse wurden mehrere wichtige funktionelle Gruppen identifiziert, darunter eine Hydroxylgruppe bei 1028,75 cm-¹ (was auf Alkohole...

Cette étude a utilisé la spectroscopie infrarouge à transformée de Fourier (FTIR) pour évaluer la composition chimique de l'extrait aqueux de feuilles d'Artemisia annua, une plante reconnue pour ses propriétés médicinales. Les feuilles ont été collectées, authentifiées et traitées par trempage dans de l'eau distillée stérile et du méthanol à l'université Joseph Sarwuan Tarka et à l'université d'Ibadan, au Nigeria. L'analyse FTIR a permis d'identifier plusieurs groupes fonctionnels clés, notamment un groupe hydroxyle à 1028,75 cm-¹ (indiquant des alcools), un alcène à...

The study investigates the effects of different application rates of poultry manure on maize growth and yield in Benue State, Nigeria in Africa. Given the critical role of maize as a staple crop in Africa and the challenges posed by declining soil fertility and high costs of chemical fertilizers, this research aims to provide insights into sustainable agricultural practices. Field experiments were conducted using a randomized complete block design to assess various rates of poultry droppings on key growth parameters such as plant height, leaf number, and overall yield. Preliminary findings...
