PREMISE OF THE STUDY Changes in the pollinator communities of marginal plant populations can affect their pollination quantity or quality. Geographic variation in pollination success can alter the reproductive advantage that female plants require to persist within gynodioecious populations. Particularly valuable is determining the pollination success at the prezygotic stage in self-compatible g...

background and aim: an important criterion for success assessment of implant-supported prostheses is marginal fit. vertical and horizontal discrepancy can result in loosening of the prosthetic screw, crestal bone resorption, peri-implantitis and loss of osseointegration. despite careful attention to waxing, investing, and casting, marginal discrepancies are inevitable. the aim of this study was...

objective: this experimental in vitro study compared marginal adaptation of indirect composite, glass-ceramic inlays and direct composite. materials and methods: seventy-five recently extracted human molars were randomly divided into three groups (n=25) and mesio-occluso-distal cavities with the same dimensions were prepared in the teeth. indirect composite and glass-ceramic inlays were fabrica...

Bio-energy from energy plants is expected to play an increasing role in the future energy system, with benefits in terms of reducing greenhouse gas emissions and improving energy security. Pistacia chinensis is believed to be one of the most promising non-food input for biodiesel production. This study focused on the marginal land availability for developing Pistacia chinensis-based bioenergy i...

This paper considers some fundamental questions concerning marginally trapped surfaces, or apparent horizons, in Cauchy data sets for the Einstein equation. An area estimate for outermost marginally trapped surfaces is proved. The proof makes use of an existence result for marginal surfaces, in the presence of barriers, curvature estimates, together with a novel surgery construction for margina...

This research combined three distinctly unique and separate measures of corruption into one corruption factor, so as to yield a robust measurement approach to further understand the political and socioeconomic variables of corruption. The findings show that a strong significant variable in measuring corruption is the personal marginal-tax rate, especially in hierarchical based nations. The high...

Knowledge of factors, which influence stress and its distribution, is of key importance to the successful production of durable restorations. One of this is the marginal geometry. The objective of this study was to evaluate, by finite element analysis (FEA), the influence of different marginal designs on the stress distribution in teeth prepared for cast metal crowns. Five margin designs were t...

Article history: Received 29 June 2013 Received in revised form 18 November 2013 Accepted 19 November 2013 Available online 12 December 2013 Constructing a duopoly model with non-constant marginal costs and a strict Pareto criterion, this paper examines welfare effects of world-price-fixing tariff reductions accompanied by adjustments of a domestic tax. If a destination-based consumption tax is...
