  • Quantifying Chlorophyll in leaves using a non-destructive method with the UniSpec-SC

    Chlorophyll is a driver of the physiological function of leaves. Quantifying chlorophyll content can provide information regarding the physiological state of leaves. Chlorophyll tends to decline rapidly when plants are under stress or during leaf senescence (Gitelson & Merzlyak 1994). It is very vital to understand the pattern of the pigment content change if we are to understand ...

  • Non-destructive analysis of concrete for corrosion studies using nuclear technique

    Chloride-induced reinforcement corrosion is the principal cause of deterioration of concrete structures in the Arabian Gulf and the world over. Preventive measures against corrosion require maintaining the chloride and sulphate concentration in concrete below the threshold limits specified by the standards. This requires monitoring the chloride and sulphate concentration in concrete, and a ...

  • Fibre optic sensors as a non–destructive tool for structural monitoring

    Structural monitoring is a diagnostic tool for detection of defects/damages and for scheduling maintenance operations. It is essential to determine the safety of the structures by Non–Destructive Testing (NDT) for evaluation of strength/integrity. This assessment is required for the repair, rehabilitation and life extension of the structure. Fibre Optic Sensors (FOS) are attractive sensing ...

    This publication 'Survey of Currently Available Non-Incineration PCB Destruction Technologies is intended to serve as a guide to available PCB destruction technologies other than incineration. The publication responds to requests for information on, and to continuing interest in alternatives to incineration. The Survey identifies more than 20 vendors who represent that they can treat and destroy ...


  • Analysis of gamma ray incoherent scattering for non-destructive testing

    An approach for the analysis of gamma ray incoherent scattering on free and binding electrons is presented for Non-destructive Testing (NDT). The method is based on computational simulation and backscattering gamma ray measurements for carbon steel walls. The results of thickness measurements for steel walls are described by the theory of the energy transfer model.Keywords: gamma ray incoherent ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...

  • Compliance Trends in 2017: what to expect, how to prepare

    Looking back on 2016, it was without doubt a year of political upheaval and increased scrutiny on the environmental, social and human rights implications of government regulations, corporate practices and consumer habits. In 2017, these changes will fuel additional compliance considerations for corporate supply chains around the world. While the future is anything but certain, our regulatory ...

  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Non–destructive radiotracer technique in characterisation of nuclear grade anion exchange resins Tulsion A–30 and Dowex 550A LC

    The present study deals with the application of non–destructive radio isotopic tracer technique to evaluate the performance of nuclear grade resins Tulsion A–30 and Dowex 550A LC. The evaluation was made by testing the performance of the two resins during iodide and bromide ion–isotopic exchange reactions. It was observed that at a constant temperature of 30°C, as the concentration of labelled ...

  • New Italian norms to regulate the non-destructive inspections in the manufacturing and in the maintenance of parts of hydraulic machinery

    Introduction This paper presents two proposals of norms (standards) which have been discussed by a Working Group of UNI (Ente Italiano di UNIficazione, Italian expression of ISO) during 1998-2000, and will be soon submitted to examination by the technical verification commission of UNI. These proposals aim to provide procedures to perform and evaluate inspections on parts of hydraulic machinery ...

  • Handheld XRF analyzer, X-MET7000, for rapid, non-destructive Drywall testing – New application note from Oxford Instruments

    The handheld XRF analyzer - X-MET7000 - offers a rapid and non-destructive solution for screening of tainted and potentially hazardous Chinese drywall and for lead inspection. At the height of the U.S. housing boom, when building materials were in short supply, American construction companies used millions of pounds of imported drywall ...

  • Effects of maturity on chlorophyll-related absorption in nectarines, measured by non-destructive time-resolved reflectance spectroscopy

    The ripening of fruits like nectarines and peaches is characterised by the decrease in chlorophyll content or colour of the fruit flesh. However, measuring the colour of fruit flesh is usually not conducted, as there is a lack of suitable techniques. Time-Resolved Reflectance Spectroscopy (TRS) is a novel technique that can measure the light absorbed by the fruit flesh. Using a laser light beam ...

  • Taxpayer dollars subsidizing destruction

    One way to correct market failures is tax shifting—raising taxes on activities that harm the environment so that their prices begin to reflect their true cost and offsetting this with a reduction in income taxes. A complimentary way to achieve this goal is subsidy shifting. Each year the world's taxpayers provide at least $700 billion in subsidies for environmentally destructive activities, such ...

  • Data destruction to go

    Mobile shredding unit reliably destroys data carriers preventing reproduction of sensitive information "Installed today - out-dated tomorrow" is a wise saying of many IT specialists. Technical progress develops at a rapid pace. Companies which are dependent on always using the newest technology, have to upgrade regularly and dispose of their waste devices. However, the hard disks contained in ...

  • Irreversible destruction of collected data with overgaining

    Introduction Recently we have encountered a growing amount of GPR users asking for help with the interpretation of their data. Most of this requests were based on a presumption that a more skilled user will be able to interpret more out of the collected data. However, the problem was not in the lack of interpretation skills, but rather with the lack of data acquisition knowledge. Most of the ...
