The need for simple and accurate methods to measure renal function is self-evident. This increases as techniques intervention become available. demand evaluation of individual kidney has increased with its role in the diagnosis follow-up unilateral disease decision making conservative or surgical treatment based on residual function. nuclear medicine this area been inhibited by confusion about conflicting methodologies. report meant provide guidance those centers that would like initiate...
There is currently a lack of published data for the performance multicopter unmanned aircraft system (UAS) vehicles, such as quadcopters and octocopters, often referred to collectively drones. With rapidly increasing popularity UAS, there interest in better characterizing this type aircraft. By studying available it will be possible develop models vehicles at scale that can accurately predict model trajectories. This paper describes wind tunnel test was recently performed U.S. Army's 7- by...
Vagus nerve stimulation (VNS) is a recognized treatment for neurological disorders, yet the surgical procedure carries significant risks. During process of isolating or cuffing vagus nerve, there danger damaging itself adjacent carotid artery jugular vein. To minimize this risk, here we introduce novel hydrogel adhesive-integrated and stretchable microdevice that provides less invasive, cuff-free option interfacing with nerve. The device features adhesive formulation enables crosslinking on...
Abstract Objective: To test the agreement between 3 common methods of glucose measurement in a population critically ill foals presenting to neonatal intensive care unit. Design: Prospective clinical study. Setting: University large animal hospital Animals: Sequentially admitted <30 days age. Interventions: Venous blood obtained from jugular vein was used for determination concentration using point‐of‐care (POC) glucometry (GLU), laboratory chemistry technique (CHEM) and multi‐electrode...
The results of a long‐term clinical study posterior composite resin are reevaluated using the Moffa‐Lugassy, Vivadent, and Leinfelder‐Goldberg standards. Occlusion (ICI/Coe, England) was selected for study, obtained from three universities compared. From these results, it is concluded that all resins should be evaluated same optical
Multicopter unmanned aircraft systems (UAS), or drones, have experienced explosive sales volume and application growth in recent years. With this comes demand for increased performance as the limits of existing technologies are reached. In order to improve design multicopter UAS aircraft, better validated prediction tools needed. This paper presents results a study aimed at using rotorcraft comprehensive analysis code CAMRAD II model rotor hover. Parametric studies were performed determine...
A computational framework to support the quantification of system uncertainties and sensitivities for rotorcraft applications is presented using NASA Design Analysis Rotorcraft (NDARC) conceptual sizing tool. 90 passenger tiltrotor configuration was used case demonstration in modeling NDARCs emission module. non-intrusive forward propagation uncertainty approach applied ensemble simulations a Monte Carlo methodology with stratified Latin hypercube sampling. An off-the-shelf software, DAKOTA,...
The Multirotor Test Bed (MTB) is a new capability for testing wide array of advanced vertical take-off and landing (VTOL) rotor configurations, with primary focus on in the U.S. Army 7- by 10-Foot Wind Tunnel at NASA Ames Research Center. MTB was designed to allow adjustment vertical, lateral, longitudinal placement each rotor, as well tilt pitch whole assembly. Each can forward 90 deg backwards 5 deg. In addition, entire 20 10 This flexibility allows system be tested many different...
In 2011, a task was initiated under the US-French Project Agreement on rotorcraft studies to collaborate design methodologies for environmentally friendly rotorcraft. This paper summarizes efforts of that collaboration. The French and US aerospace agencies, ONERA NASA, have their own software toolsets approaches design. first step this research effort understand how impact environment, with initial focus air pollution. Second, similar baseline helicopters were developed passenger transport...
Abstract The purpose of this study was to see if the root surface topography teeth, stored in saline and subsequently treated with citric acid, differred from teeth that were immediately upon extraction. 12 freshly extracted adult human permanent proximal surfaces free caries periodontal disease, succession. crowns removed at level attachment, sectioned buccallingually a treatment area deligniated on each section. 6 planed expose dentin (D) scaled remove adherent tissue leave cementum (C)...
In November 2019, NASA completed the first wind tunnel test entry of Multirotor Test Bed (MTB), a new capability for advanced VTOL rotorcraft configurations. The MTB had been under development since 2017 when need arose an easily reconfigurable stand multirotor aircraft With wide-ranging assortment currently targeted at Urban Air Mobility and Unmanned Aircraft System applications, there is validation data that will increase confidence in computational modeling tools being used to develop...
Multiple metrics are applied to the design of a large civil tiltrotor, integrating minimum cost and environmental impact. The mission is passenger transport with similar range capacity regional jet. Separate aircraft designs generated for empty weight, fuel burn, A metric specifically developed employed evaluate emissions. using NDARC rotorcraft sizing code, rotor analysis performed CAMRAD II aeromechanics code. Design parameters such as wing loading, disk cruise altitude varied minimize...
Convective weather is currently the largest contributor to air traffic delays in United States. In order make effective flow management decisions mitigate these delays, forecasts must be made as early and accurately possible. A forecast product that could used convective impacts Consolidated Storm Prediction for Aviation. This provides of cloud water content top heights at 0- 8-hour look-ahead times. The objective this study was examine a method predicting impact on sector capacities using...
