  Abstract In southeastern Nigeria, soil and gully erosion and landslides are responsible for the widespread destructions of human, animal and plant lives, domestic, industrial and commercial property, transportation and communication systems, degradation of arable lands, contamination of surface and groundwater supplies, isolation of settlements and migration of communities. This account presents some of the results of research and studies of gully erosion and landslides carried out over the years in parts of southeastern States of Abia, Anambra, Enugu, Ebonyi and Imo States. Gully erosion is attributed to natural and anthropogenic causes, with the latter being most prevalent. Gully initiation is the result of localized erosion by surface runoff and soil eluviation associated with rainfall events of high intensity. Erosion is frequently concentrated where the forest cover has been removed for agricultural, urbanization and construction purposes and also at sites of u...

 Abstract In atmospheric conditions, most of the metals and alloys are unstable and prone to corrosion. The corrosion potentially affects industrial equipment, reduce the shelf life of the infrastructure assets and the quality of the environment. Therefore, it is essential to control the corrosion to save considerable expenses in materials, equipment, and structure. This review article provides a brief overview and impact of corrosion, recent incidence related to corrosion, incurred cost, and mitigation methods of corrosion.

Introduction It is significant to note that user acceptance and confidence are crucial for further development of any new technology [1,2]. Businesses have facilitated or planning to facilitate their business platform to increase personnel efficiency, marketing improvement, cost reduction and increase profitability. Therefore, recognition the needs and acceptance of individuals is the beginning stage of any businesses and this understanding would be helpful to find the way of future development [3-5]. In general, acceptance is defined as “an antagonism to the term refusal and means the positive decision to use an innovation” [6-8]. Decision makers need to know the issues that influence on users’ decision to use a particular system, so they would be able to take them into account during the development phase [7,8]. Several researches developed theories and models to describe and analyze user acceptance and each of these models determines different factors to explain user acceptance ...
