Choosing the best chops, steaks or other fresh meat products is a tough job. Its a delicate balancing of leanness, juiciness, taste, marbling and more. Increasingly, meat processors use electronic devices and equipment---such as optical probes, ultrasonic sensors and digital cameras---to evaluate critical fat to meat ratios. In 2003, for instance, electronic devices determined pricing for more than 80 percent of the almost $7.5 billion worth of swine processed in the United States. Multiple devices, as well as different methods for evaluating results can, however, produce different data.
The National Institute of Standards and Technology (NIST) has joined meat industry counterparts, producers, device manufacturers, the United States Department of Agriculture (USDA) and ASTM International (formerly the American Society for Testing and Materials) to standardize the measuring process for pork, beef and, eventually, poultry.
In February, ASTM committees, representing all concerned parties, approved the first two of four draft standards to cover key aspects of the electronic methods used to determine the value of live animals, carcasses and individual cuts. The approved standards outline requirements for installation, operator training, operation, verification, inspection, maintenance, design and construction of devices or systems. The remaining two standards, expected to be approved in the spring of 2004, cover calibration, accuracy and standardized equations for pricing meat. The final standards are expected to be incorporated into new USDA regulations.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
