  • 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 ...

  • 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 ...

  • 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 ...

  • What`s the Best Air Pollution Control Technology for My Process?

    Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

  • Emergent Standards & Expectations on Corporate Conduct: Why This Matters To Your Business [WEBINAR]

    As governments worldwide continue to set rigorous standards for corporate conduct, businesses are faced with ever-increasing regulatory requirements to comply with these growing initiatives. The United Nations Guiding Principles on Business and Human Rights reflect the ...

  • Transformational adaptation – when climate change means business as usual is no longer possible

    1. A lesson from the past Deep in the central Sahara, a crumbling mud-brick town sits at the edge of a dry lake bed. This is the medieval town of Germa, in southwestern Libya, one of a string of settlements along the Wadi al-Ajal, a valley defined by the towering dunes of the Ubari Sand Sea to the north, and the black cliffs of the Messak Settafet plateau to the south. Germa is romantic ...

  • From Drought To Flooding: California Struggles With Turnaround

    In a drastic about-face, California has gone from historically desperate drought conditions to an inundation of water that has brought its own set of problems.  In one indicator of the dramatic difference, snowpack on the Sierra mountains recently measured 135 percent of its seasonal average. “We haven’t seen an event of this magnitude in at least a decade,” Mike ...

  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...
