Sonic anemometer/thermometers are used to measure turbulent components of the atmosphere except for confined areas and very close to the ground. These practices apply to the use of these instruments for field measurement of the wind, sonic temperature, and atmospheric turbulence components. The quasi-instantaneous velocity component measurements are averaged over user-selected sampling times ...

The height of surface profile has been shown to be a factor in the performance of various coatings applied to steel. For this reason, surface profile should be measured prior to coating application to ensure that it meets that specified. The instruments described are readily portable and sufficiently sturdy for use in the field. Note 1—Optical microscope methods serve as a referee ...

Atmospheric pressure is one of the basic variables used by meteorologists to describe the state of the atmosphere. The measurement of atmospheric pressure is needed when differences from “standard” pressure conditions must be accounted for in some scientific and engineering applications involving pressure dependent variables. These methods provide a means of measuring atmospheric ...

The AGRI-THERM II™ is a non-contact infrared thermometer that is used extensively in agronomy and environmental science research. It is capable of measuring surface temperatures of crops or individual leaves and reading out that temperature, ambient dry-bulb air temperature and the difference between them. This instrument has ...

It is understood that the policy package is to be adopted by the European Commission (EC) on 18 June. The measures will focus on food and construction waste and will look to EU commitments beyond the current 2020 targets, which instruct member states to recycle 50% of their municipal solid waste and 70% of construction waste. Speaking at Brussels’ Green Week conference, environment ...

Scientists recently spotted several bowhead whales (Balaena mysticetus) near Svalbard where they have only been spotted a few times in the last several decades. Two weeks of searching on a recent research mission to the arctic waters between Greenland and the Svalbard Archipelago ( Norway) was rewarded with 8 whale sightings, several of which involved multiple whales (3, 3 and 7 plus whales ...

Researchers of Wageningen University provide the world’s first spatiotemporally explicit model that simulates the behaviour and fate of engineered nanoparticles (ENPs) in surface waters. Wageningen researcher Bart Koelmans: “This is important in order to assure safe nanotechnology. We do need to have an assessment of the risks of ENPs to man and the environment.” ...

Undoubtedly, the biggest challenge of deep level mining is providing a safe environment for miners. Today, gold and platinum mines descend as far as 5km below surface in some cases. In this extreme environment, virgin rock temperatures often exceed 60°C, requiring sophisticated cooling methods and equipment to reduce temperatures to safe levels for miners to work in. Due to the ...

Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions. Sea level rise in one of the major consequences of global warming, but it is much more difficult to ...
