Abstract: Total field aeromagnetic anomaly data obtained for the Koton-Karifi area, Nigeria were used for the present study. The original data were part of the aeromagnetic map of the total magnetic field intensity in half-degree sheet acquired from the Nigerian Geological survey Agency (NGSA). The superimposed ground – levelled aeromagnetic anomaly map on the geology of the area suggests a NE-SW fault line, marking a boundary between the migmatites and granitoids. It is therefore suggested that the metamorphic phase change at this boundary was a major tectonic event in the area.

Abstract: Constantly in developing countries, development civil had been significant and effective in country’s development. Based on this fact and rapid development necessity in country especially in plan and civil field, time would be main scale of project success beside quality control, stability, resistance  in these kinds of plan schemes. Therefore, manager’s access to a method along with accurate and correct time estimation and stability control and factor resistance help them to consider appropriate plan for various resource. This matter as the most strategic collection of storage cellars is so crucial in the field of projects of wheat concrete sylvan because delay at this sylvan’s plan projects accomplishment and also instability would disorder balance and include high price. Available scheme has studied time evaluation and concrete sylvan stability by using neural network that layers models would be presented in order to estimate time duration and real stability of concrete sylvan after introducing neural network.

Abstract: Finding the zeros of nonlinear functions has wide applications in engineering, in scientific computations and various other fields. In these problems we seek methods that lead to approximate solutions. Sometimes the applications of the iterative methods depending on the derivatives are restricted in engineering. In this paper, we propose some iterative formulae without derivatives. The convergence analysis shows that these methods are cubically convergent. The best property of these schemes is that they are derivative free. Several numerical examples are given to illustrate the efficiency and performance of the proposed methods.

ABSTRACT: Fatal epidemics such as the Middle East respiratory syndrome coronavirus, Ebola, Novel swine-origin influenza, severe acute respiratory syndrome, Zika virus infection, and Nipa virus infection, including mpox and severe acute respiratory syndrome coronavirus 2, which were relatively recently prevalent worldwide, and the mentioned diseases were infected to humans due to contact with host animals. Also, HIV, one of the worst diseases in human history, was also zoonosis. Monkeypox virus (MPXV) is a complex cytoplasmic double-stranded DNA virus, belonging to the genus Orthopoxvirus (OPXV), family Poxviridae. Monkeypox virus is an emerging zoonotic disease and can infect a wide range of mammal species, including Human beings, monkeys, anteaters, hedgehogs, prairie dogs, squirrels, shrews and dogs. The virus can be transmitted from animal-to-human, human-to-human and from a contaminated environment-to-human. There has been a single report of sick people transmitting Monkeypox virus to animals (a dog). Mpox symptoms usually appear 6–13 days (up to 21 days) after infection. Methods for treating mpox include supportive care, medication such as anti-virals, tecovirimat, brincidofovir and cdofovir, and vaccinia immune globulin. Mpox vaccines are available for primary prevention (pre-exposure) and post-exposure vaccination for persons and communities at risk of mpox. This paper provides a brief historical overview of mpox morphology, transmission, clinical signs, diagnosis, Differential Diagnosis, treatment and prevention and control as well as its zoonosis.
