Understanding and development of combined acoustic and magnetic actuation of Ni₂MnGa single crystals
Ni-Mn-Ga based ferromagnetic shape memory alloys (FSMAs) have emerged as a promising new class of active materials capable of producing a large (several %) magnetic-field-induced strain (MFIS). FSMAs still have several characteristic shortcomings that may limit their potential applications. A …

Assessment of Farmers Market Practices and Characteristics to Inform the Development of Tailored Educational Materials
… to them. The Food Safety Modernization Act (FSMA) was passed in 2011, and shifted the food safety paradigm from a reactive to proactive approach introducing seven different rules including the Preventive Controls for Human Foods (PCHFR) and the Produce Safety Rule (PSR). Each FSMA rule does …

The role of the regulator, auditor and banker: the limits of regulation
… of the Financial Services and Markets Act 2000 (FSMA 2000) or the operations of the single controller and regulator, the Financial Services Authority. This work compares the Bank of England's and the Financial Services Authority's regimes to argue that: The supervision of banks and credit …

Acoustic assisted actuation of Ni-Mn-Ga ferromagnetic shape memory alloys
Ferromagnetic shape memory alloys (FSMA) have been shown in recent work to exhibit large magnetic field induced strains. The material generally requires a large threshold field (of order 3-4 kOe) to initiate the strain. Thus, the power requirements are large and actuators based on these materials …

Fabrication and characterization of Ni-Mn-Ga ferromagnetic shape-memory alloy composites
Ferromagnetic shape-memory alloys (FSMAs) are a recently-developed class of active materials which show large extensional strains when a magnetic field is applied. Shear strains of 6% have been observed at room temperature in martensitic Ni-Mn-Ga single crystals. The strain effect in Ni-Mn-Ga FSMAs …

Pulse-field actuation of collinear magnetic single crystals
Ferromagnetic shape memory alloys (FSMAs) are a class of alloys that exhibits the shape memory effect, as in the alloy nickel-titanium, sometimes known as Nitinol. In FSMAs, though, the shape changes are not brought on just by changes in temperature or mechanical stresses, but can also be driven by …

Evaluating the Cross-Contamination Risks of Salmonella and Generic Escherichia coli on Agricultural Ground Covers in Produce Pre-Harvest Production
… Administration Food Safety Modernization Act (FSMA) Produce Safety Rule (PSR) prohibits the harvest of dropped fruits and vegetables due to potential microbial contamination. Under the FSMA PSR dropped produce includes (i) produce that has detached from the parent plant and unintentionally …

Magneto-mechanical properties and applications of Ni-Mn-Ga ferromagnetic shape memory alloy
Ferromagnetic shape memory alloys (FSMA's) have shown large strains under magnetic field as magnetic variants in the rnartensite rearrange to accommodate the applied field. The theoretical maximum field-induced strain is 6.3% in Ni-Mn-Ga FSMA, and results of 6.1% are presented. These strain …

The Food Safety Modernization Act: a summary of the act, education, and implementation.
Since the Food Safety Modernization Act (FSMA) was signed into law in 2011, the government has taken huge strides toward making the food safety system preventive rather than reactive. Specifically, the Preventive Controls for Human Food (PCHF) final rule has required collaboration from government …

Design and characterization of acoustic pulse shape memory alloy actuators
… Ni-Mn-Ga ferromagnetic shape memory alloys (FSMAs) are active materials which produce strain when a magnetic field is applied. The large saturation strain (6%) of Ni-Mn-Ga, and material energy density comparable to piezoelectric ceramics make Ni- Mn-Ga an interesting active material. However, …

Farm food safety plans: customizing educational materials for small-scale and campus-based farms
… passing of the Food Safety Modernization Act (FSMA) in 2011 addresses mandated accountability for large-scale agriculture within the Produce Safety Rule, but leaves many small farms exempt from regulation, including the types of farms targeted within this study. A need for a curriculum …

Thermal inactivation of Salmonella and Escherichia coli O157:H7 in heat treated, recycled used cooking oil
… of the Food Safety Modernization Act (FSMA), which enforces a zero tolerance policy for Salmonella in all pet foods, the microbiological safety of these products has become an area of focus for the industry. Objectives of this study were to (i) understand lethality of a selective set of …

An analysis of ferromagnetic shape memory alloys produced by melt spinning, sputtering and pulsed laser deposition.
Ferromagnetic shape memory alloys (FSMA) have recently attracted much interest and research because of their large magnetic-field induced strain. Strains of up to 10% have been reported in single crystals of Ni2MnGa at room temperature. The mechanism of twin boundary motion is understood to be …
