Ubiquitous Chlorine Performs Vital Tasks In Turf
Although chlorine (CI) is the most abundant micronutrient in most plant tissues, Turner and Hummel (1992) reported that "deficiency symptoms or beneficial responses of turfgrasses to Cl have not been reported." This apparent inconsistency reflects the simple fact that Cl is ubiquitous in nature, and deficiency symptoms are never observed in turfgrasses or any other plants. It was not until 1954...

متن کاملFilling the Gaps: Dentist Disparities along the Rural Urban Continuum

Dentist workforce availability has implications for oral health care access and utilization, which in turn can affect the quality of life, health, and productivity of rural residents. In addition, dentists form part of the non-tradable services sector, and its erosion may affect the vitality of...
متن کاملThe Complexity of Finding Most Vital
Let G(V; E) be a graph (either directed or undirected) with a non-negative length`(e) associated with each arc e in E. For two speciied nodes s and t in V , the k most vital arcs (or nodes) are those k arcs (nodes) whose removal maximizes the increase in the length of the shortest path from s to t. We prove that nding the k most vital arcs (or nodes) is NP-hard, even when all arcs have unit len...
متن کاملA Comparative Investigation of Marginal Adaptation and Surface Defects of MTA and Root MTA as Two Root End Filling Materials
Introduction: This study was carried out to compare two retrograde filling materials entitled mineral trioxide aggregate (MTA) and Root MTA (RMTA) in regard to their marginal adaptation and surface defects. Method: In this study twenty extracted human teeth were used. In all teeth after cleaning and shaping, the root canals were obturated by gutta-percha and root canal sealer. After that in eac...
