OBJECTIVES To test the null hypothesis of no difference in the implant failure rates, marginal bone loss (MBL) and postoperative infection in patients who received platform-switched implants or platform-matched implants, against the alternative hypothesis of a difference. DATA Main search terms used in combination: dental implant, oral implant, platform switch, switched platform, platform mis...

This study attempted to investigate the impact of teacher’s code-switching on the acquisition of a problematic grammatical structure, namely, object relative clauses, by intermediate EFL learners. Moreover, a secondary objective of the study was to determine the EFL learners’ attitudes and opinions regarding the effectiveness of teacher’s code-switching in their learning of a specific aspect of...

This paper discussed the discursive strategies in selected political rally campaigns of the 2011 elections in Southwestern Nigeria with a view to revealing the dynamics of political persuasion and mobilization in contemporary natural political communication in Nigeria. The data for the study were obtained from two political rallies in each of the six Southwestern states in Nigeria, making a tot...

Selective harmonics elimination (SHE) is one of the prominent technique that is used to produce required fundamental voltage of multilevel inverters with elimination of selective harmonic orders. The SHE equations are nonlinear equations and are also termed transcendental equations owing to the fact that these equations contain trigonometric terms. Attempt has been made in previous works to sol...

This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...

The modular multilevel converters (MMCs) are widely used in different applications in recent years. Due to lowloss operation, compactness and high modularity, MMC is greatly attractive for high voltage direct current (HVDC) applications. The HVDC station costs and losses are highly related to the switching frequency, capacitor voltage ripple and power quality; which are influenced by modulation...

Due to the exponentially increasing connectivity and bandwidth demand from the Internet, the most advanced examples of medium-scale fast reconfigurable photonic integrated switch circuits are offered by research carried out for dataand computer-communication applications, where network flexibility at a high speed and high connectivity are provided to suit network demand. Recently we have protot...
