Surface Transportation Surveillance from Unmanned Aerial Vehicles
Unmanned Aerial Vehicles (UAVs) promise a low cost means to achieve a "bird's eye view" and a rapid response for a wide array of transportation operations and planning applications, including incident response, coordination among a network of traffic signals, traveler information, emergency vehicle guidance, and measurement of typical roadway usage. However, many obstacles to operational use ex...
متن کاملPlant-associated microorganisms: a view from the scope of microbiology.
Microorganisms interact with plants because plants offer a wide diversity of habitats including the phyllosphere (aerial plant part), the rhizosphere (zone of influence of the root system), and the endosphere (internal transport system) [3, 5]. Interactions of epiphytes, rhizophytes or endophytes may be detrimental or beneficial for either the microorganism or the plant and may be classified as...
متن کاملSurface Microbiology of Smartphone Screen Protectors Among Healthcare Professionals
BACKGROUND The use of smartphones with touch screens has become a norm for healthcare professionals (HCP). The risk of smart screen contamination has been proven, and guidelines are available to deal with possible contamination. A large number of smartphone users apply plastic or glass screen protectors onto their mobile phone screens to prevent scratches. However, these materials are not scrat...
متن کاملThe Washington aerial spray drift study: assessment of off-target organophosphorus insecticide atmospheric movement by plant surface volatilization
Post-application pesticide emissions from wetted leaf surfaces and soil may present a significant pathway of exposure to humans in nearby residential communities. In this study, high volume air sampling was performed to measure airborne concentrations of the pesticide methamidophos in a residential community in close proximity to aerial spraying. Sampling occurred before, during and 24 h post-a...
متن کاملSmall unmanned aerial vehicles (micro-UAVs, drones) in plant ecology1
PREMISE OF THE STUDY Low-elevation surveys with small aerial drones (micro-unmanned aerial vehicles [UAVs]) may be used for a wide variety of applications in plant ecology, including mapping vegetation over small- to medium-sized regions. We provide an overview of methods and procedures for conducting surveys and illustrate some of these applications. METHODS Aerial images were obtained by fl...
