2021
The Controlled Odor Mimic Permeation System is a simple, field-portable, low-cost method of odor delivery for olfactory testing and training. It is constructed of an odorant retained on an adsorbent material and contained inside of a permeable polymer bag allowing controlled release of the odorant vapor over time.

Driving Simulation in the Clinic: Testing Visual Exploratory Behavior in Daily Life Activities in Patients with Visual Field Defects

Patients with visual deficits after stroke report about different constraints in daily life most likely due to variable compensatory strategies, which are difficult to differentiate in clinical routine. We present a clinical set-up which allows measurement of different compensatory head- and eye-movement-strategies and evaluating their effects on driving performance.

Anxiety Testing

2023
Anxiety is a commonly observed behavioral disorder that stems from fear. It is described as increased restlessness, or unpleasant feelings of fear over anticipated events. Experimenters often use rodent models to better understand anxiety disorders in humans. They use different paradigms, like exposing rodents to bright spaces or loud sounds, which are known to induce fear. These tests combined with other interventions such as surgery or drug-administration may assist researchers in pinpointing...

2026
Reliable and accurate forms of field-deployable DNA analysis are crucial for many industries. This paper offers two methods for environmental microbial analysis in the field: 1) the isolation of microbial DNA from environmental samples using a biological extraction field kit, and 2) the analysis of DNA via the field qPCR unit.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Wood is a ubiquitous material that has been used in construction from the earliest times. Wood is a renewable, sustainable material with great aesthetic value. Today, there are probably more buildings constructed with wood than any other structural material. Many of these buildings are singlefamily residences, but many larger apartment buildings, as well as commercial and industrial buildings,...
FAQs
Defined controls help distinguish biological patterns from effects introduced by the test itself or by inconsistent measurement conditions. In Field Testing, standardized protocols establish comparable ways to record species presence, behavior, physiology, or environmental quality. This consistency makes results more useful when researchers compare sites with different natural conditions.
Natural variation among study sites can change observed species presence, behavior, physiology, or environmental quality even when methods remain consistent. Standardized protocols and defined controls help separate these real biological or ecological differences from variation caused by sampling practice. This matters because field results should reflect environmental stressors and conditions organisms experience in nature.
Comparing field results with laboratory findings shows whether an observed response remains relevant under natural environmental variation. Laboratory conditions can provide controlled evidence, whereas field measurements capture organisms or ecological conditions at study sites. Using both perspectives helps researchers judge ecological relevance, identify biological change, and interpret findings for conservation, monitoring, or public-health decisions.
Researchers collect samples or record observations at defined study sites, apply standardized protocols, and use portable instruments when measurements must be made outside the laboratory. They then measure selected variables, such as species presence, behavior, physiology, or environmental quality, while maintaining defined controls. Comparable procedures across locations support consistent evaluation and meaningful comparisons.
Field Testing is especially useful for biodiversity surveys, disease surveillance, conservation planning, and ecological monitoring. It supplies evidence from settings where organisms and environmental conditions vary, rather than relying only on controlled laboratory observations. The resulting measurements can reveal biological responses to environmental stressors and provide information relevant to management or public-health decisions.
Results become more informative when researchers compare them across locations or with laboratory findings. Differences may help identify biological change, while variation among sites can show how natural conditions or environmental stressors relate to measured traits or environmental quality. Interpretation therefore depends not only on the measurement itself, but also on the comparison framework connecting observations with ecological or management questions.
