Technology is advancing ever so steadily and all efforts are geared towards the automation of processes to make human life easier. The fourth industrial revolution is driving the use of technology in production processes and organizations such as health, agriculture and manufacturing among others to improve the functionalities of said processes. Machine learning and artificial intelligence, as well as the Internet of Things and cloud computing, are some of the current hot technologies. Agriculture is one of the most crucial areas in human survival and has therefore seen more technological resources directed towards improving production while minimizing costs. The process of realizing this vision however hasn't been a hurdle free and this paper strives to take a peek into the situation of technology use (Internet of Things) in agriculture to understand some of the successes, challenges and gaps that need filling. To effectively shed some light on the situation this paper reviews research work from scholars in the field of precision agriculture with a focus on their proposed solutions, Equipment and technologies employed such as (ZigBee, Low PAN, Bluetooth, GSM, Wi-Fi, AI and Cloud computing) and compares between solutions offered by the researchers by identifying gaps

This paper explores the factors that influence the implementation of m-learning and proposes a model for implementing m-learning in Tanzania. The study was conducted in ten secondary schools in the Kilimanjaro region in Tanzania. Purposive and convenience sampling techniques were used to determine students majoring in science subjects. Findings indicate that majority of students own mobile phones and have access to the Internet connectivity. However, m-learning platforms that are currently in place are not viable solution in all contexts and not necessarily the best solution. Therefore, the design of m-learning content should focus on learning profile and personal needs such as location and affordability. A framework that considers four factors: user satisfaction, pedagogy, technology, and economy of use are proposed for Tanzanian context. It is concluded that education stakeholders should consider the opportunities of technology in education in order to boost knowledge sharing among students.

Bubonic plague is a serious bacterial disease, mainly transmitted to human beings and rodents through flea bite. However, the disease may also be transmitted upon the interaction with the infected materials or surfaces in the environment. In this study, a deterministic model for bubonic plague disease with Yersinia pestis in the environment is developed and analyzed. Conditions for existence and stability of the equilibrium points are established. Using Jacobian method disease free equilibrium (DFE) point, E0 was proved to be locally asymptotically stable. The Metzler matrix method was used to prove that the DFE was globally asymptotically stable when R0 < 1. By applying Lyapunov stability theory and La Salles invariant principle, we prove that the endemic equilibrium point of system is globally asymptotically stable when R0 > 1. Numerical simulations are done to verify the analytical predictions. The results show that bubonic plague can effectively be controlled or even be eradicated if efforts are made to ensure that there are effective and timely control strategies.
