To date, the majority of mobile network operator (MNO) customers have not used mobile Internet (MI) offerings. Therefore, it is important to gain a better understanding of (1) how MNO customers perceive MI attributes, (2) how these perceptions are related to MI acceptance, and (3) the extent to which these judgments differ as a function of an individual’s adoption status (actual compared to pot...

This study provides empirical findings on determinants of mobile network operators’ (MNO) choices of cross-border entry modes. Arguments mainly from transaction cost theory are used to derive hypotheses and research questions on factors explaining entry mode selection decisions between (1) minority versus majority equity share purchases, and (2) engagements in established operations versus gree...

Effectiveness of permanganate (MnO 4 ) injection for in situ chemical oxidation is often controlled by the natural oxidant demand (NOD) of the aquifer solids. In this work, a simple procedure was developed and applied to generate a database of NOD kinetic parameters for six different models for 50 different aquifer materials. Representing oxidant consumption as an initial instantaneous reaction...

Mesoporous MnO(2) nanowire array architecture exhibits enhanced capacitive and charge/discharge performance for electrochemical capacitors.

A new chemolithotrophic bacterial metabolism was discovered in anaerobic marine enrichment cultures. Cultures in defined medium with elemental sulfur (S) and amorphous ferric hydroxide (FeOOH) as sole substrates showed intense formation of sulfate. Furthermore, precipitation of ferrous sulfide and pyrite was observed. The transformations were accompanied by growth of slightly curved, rod-shaped...

Caching popular content at the wireless edge is recently proposed as a means to reduce congestion at the backbone of cellular networks. The two main actors involved are Mobile Network Operators (MNOs) and Content Providers (CPs). In this work, we consider the following arrangement: an MNO pre-installs memory on its wireless equipment (e.g. Base Stations) and invites a unique CP to use them, wit...

Motivated by the growing significance of media choice theories, the accelerating development of information technology, the rapid pace of globalization and multinationalism, and the paucity of empirical studies of cross-cultural media choice, this paper investigates the role of culture in media choice behavior within multinational organizational (MNO) contexts. Specifically, it focuses on inves...

A H 2 O /MnO molar ratio as low 0.03 can affect the redox activity of MnO particles and their reactivity in natural systems.

In the present investigation, ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites were fabricated via a facile hydrothermal method and were calcined at 300 °C for 3 h. Synthesis of ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites optimized by the different weight percentages. The synthesized photocatalyst...

Mn-based materials have been widely applied in the environmental catalysis field for their excellent redox properties. Here, three kinds of crystallite manganese oxides (pyrolusite, cryptomelane and todorokite) with different tunnel sizes (MnO(1 × 1), MnO(2 2), MnO(3 3)) were prepared by hydrothermal method, catalytic performance complete oxidation diesel vehicle exhaust tested. The highest act...
