Background and purpose : Zinc has important effects on human health, specially on structural and functional activities of immune system. This study was carried out to examine the in vitro cytotoxic effects of Zinc on Raji and Molt-4cell line. Materials and methods : Ïn this study (by cell culture) the cell line was exposed to different concentration of Zinc followed by incubation (37 c, 5%...
Face expression recognition is useful for designing new interactive devices offering the possibility of new ways for human to interact with computer systems. In this paper we develop a facial expressions analysis and synthesis system. The analysis part of the system is based on the facial features extracted from facial feature points (FFP) in frontal image sequences. Selected facial feature poi...
A basic question in computational geometry is how to find the relationship between a set of points and a line in a real plane. In this paper, we present multidimensional data structures for N points that allow answering the following queries for any given input line: (1) estimate in O(log N) time the number of points below the line; (2) return in O(log N + k) time the k ≤ N points that are belo...
Background and purpose: One of the major challenges for dentists is providing the patients with a crown of appropriate marginal fit and marginal gap. Preparation of a 135° finish line has some advantages such as technical ease and appropriate finish line record. Nevertheless, few studies investigated this type of finish line. The current study aimed at comparing marginal fit and marginal gap in...
background: zinc has significant effects on structural and functional activities of many proteins and enzymes involved in biological activities, especially the regulation of immune-system. symptoms of zinc toxicity include nausea/vomiting, fever, cough, diarrhea, fatigue, neuropathy, and dehydration. further signs include growth retardation, altered iron function, anemia, copper deficiency, dec...

1. Introduction and statement of results. "Let three points be specified on a line. Then one of the points is in the interior of the line segment joining the other two, and one of the points is exterior to the line segment joining the other two." This elementary statement concerning the ordering of three points on a line is capable of various extensions. Thus, e.g., it is easy to prove the foll...
