Research background: We develop a conceptual framework based on a systematic and comprehensive literature review on smartphones as consumption tools globally. Purpose of the article: Building our argument by drawing on data collected from Comscore, Econsultancy, and Statista, we performed analyses and made estimates regarding the adoption of Internet-enabled devices for shopping purposes: selected retail and shopping activities of EU smartphone users, most popular mobile shopping apps in the U.S. (by reach), adults in the EU who never make purchases on mobile devices (by gender), and consumers who use a mobile device for product research while shopping in-store worldwide (by country). Methods: The data for this research were gathered via an online survey questionnaire and were analyzed through structural equation modeling on a sample of 4,200 respondents. Findings & Value added: Smartphones have permeated the online community swiftly. The difficult task retailers confront is in obtaining consumers’ mutual support in supplying the information required to provide a customized shopping experience. Mobile payment privacy is associated with apprehensions that users may have concerning what will become of the data supplied when they adopt mobile payment. A satisfactory array of facilitating circumstances brings about greater purpose to adopt mobile shopping applications, especially when diverse viable functions such as convenience and swift purchase are provided. Intention to raise subsequent benefits from mobile buying should harmonize the lasting value predisposition of the mobile purchasers. The essential issue encountered by the service suppliers is how to turn the developing mobile payment operation into financial earnings.

Worldwide the processes of erosion, transport and sedimentation have a significant social, economic and environmental impact. In the past decade the most important external factor that has significantly increased the erosion and sediment process is the human factor throughout its daily activities. The changes of land cover and use, the intensive deforestation, urbanization and infrastructure development, sand extraction from river beds alter the natural watercourse and thus leading to erosion, sediment transportation and finally to the silting of rivers and reservoirs. The process of erosion and sedimentation occurs, among other areas, in the hydro-technical constructions with significant effects. In the next 30 years it’s expected to lose more than 50% of the storage capacity of the reservoirs in the world due to the silting phenomenon. The control and monitor of the sediment dynamics represents a critical component in the sustainable management of water resources. Also the understanding of the involved phenomena is essential in order to develop solution for reducing the sediment and erosion that occur and adopt measures to extend the life of the reservoirs. This paper taps the solution of mathematical modelling using dedicated software in order to establish the morphological changes that occur in Ogrezeni-Crivina reservoir, located on the river Arges.

The project of preventing the natural hazards and protection against floods of city Babadag has been designed to protect river banks of Tabana brook and its tributaries inside the area of city Babadag, against floods and silting phenomenon. The project contributes to the protection of infrastructure and social economic objectives, being in danger to deteriorate or even to be destroyed if this project will not be implemented. Aside protection of infrastructure and economic objectives, this study has another extremely important purpose for the community protection and improvement of the environmental quality and living standards from the area.
