Objective: The objective of this research is to examine PCB compounds in the Persian Gulf in the Southern Pars area. Methods: In the research, 6 stations were sampled: Asalouyeh Port, Kangan Site, Mehr Petro Kima Petrochemical, 4th Refinery in Southern Pasr, Taheri Port and Aria Sasol Polymer. To sample water in the stations determined, one-liter sampling bottles of dark glass were used. In eac...

Background: The natural radioactivity level and the radon concentration of soil were measured at four important geothermal area located in Dikili geothermal region, Turkey. Materials and Methods: The natural radionuclide content of soil samples were measured by NaI(Tl) gamma spectrometer system and the soil radon concentration were determined using Kodak-Pethe LR-115 Type II Solid State Nuclear...

INTRODUCTION In the treatment of chronic wounds the wound surface area change over time is useful parameter in assessment of the applied therapy plan. The more precise the method of wound area measurement the earlier may be identified and changed inappropriate treatment plan. Digital planimetry may be used in wound area measurement and therapy assessment when it is properly used, but the common...

This paper is Part 4 of our four-part series of paper on the development of a general framework for error analysis in measurement-based geographic information systems (MBGIS). In this paper, we discuss the error analysis problems in length and area measurements under measurement error (ME) of the defining points. In line with the basic ME model constructed in Part 1 of this series, we formulate...

ABSTRACT- The evaluation of leaf area and leaf nutritional value is important for crop growth modeling and estimations of its performance. The purpose of this study was to use image processing techniques to develop an economical method to ease the assessment of nutrient status and leaf area (LA) of plants and to compare the outcomes of this method with linear models. Leaf area and leaf chloroph...

Introduction: Age-related Macular Degeneration (AMD) is one of the most important causes of irreversible  blindness in the developed world and  prevents the affected  person from  performing simple tasks such  as  reading,  driving  and  facial  recognition.  In  the  AMD,  new  blood  vessels  grow  underneath  the  retina  in  a  process  called  choroidal  neovascularisation  (CNV).  There  ...

Due to limitations of 0.618 pole method, the triangle method and the champ ground resistance tester method on grounding resistance measurement of transmission lines and towers under conditions of complex landscape in a mountainous area, it adopts a generalized three-electrode grounding resistance measurement method which arranges electrode flexibly in the grounding resistance measurement of tra...

Efficacy of potential treatments for myocardial infarction (MI) is commonly assessed by histological measurement of infarct size in rodent models. In experiments involving an acute MI setting, measurement of the infarcted area in tissue sections of the left ventricle is a standard approach to determine infarct size. This approach has also been used in the chronic infarct setting to measure infa...

The concept of phasor measurement and its application in power system monitoring and control are introduced in this paper. The example of application of PMU in a Campus Wide Area Monitoring System (WAMS) is then elaborated. With the availability of synchrophasor data measurement, it makes possible to establish the power system monitoring by directly employing spectral analysis of power or phase...
