The non-destructive Meyer method was evaluated to determine the bark volume of beech (Fagus orientalis Lipsky) stands in north of Iran. The sample size was 185 standing trees collected from 4 geographical aspects (north, south, west and east) aspects. The constant k values and bark thickness (2e mm) of 185 standing trees were used to calculate the bark volume by the Meyer method. In this study,...

Non-Destructive Testing & Evaluation methods are developed to inspect and investigate materials and structures. Ultrasonic Testing is an NDT method can be used for measuring the thickness of objects, as one of its significant applications. The objective of this paper is designing and applying an intelligent UT fuzzy control system for evaluating the thickness of thin metal objects in a range of...

The Satisfactory condition pavements remains key consideration development infrastructure, especially countries with an aggressive environment. Innovative materials that could remarkably increase service life infrastructure are being ...

OBJECTIVE To elucidate whether differences in the destructive tissue process in cartilage and bone in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) can be recognised by different release patterns of molecular fragments derived from joint tissue. METHODS Aggrecan, cartilage oligomeric matrix protein (COMP), and bone sialoprotein (BSP) were quantified by immunoassays in knee joint syn...
