The COSMED K5 in Breath-by-Breath and Mixing Chamber Mode at Low to High Intensities

Medicine & Science in Sports & Exercise, 2019
ABSTRACT Purpose The portable metabolic analyzer COSMED K5 (Rome, Italy) allows for switching between breath-by-breath (BBB) and dynamic micro-mixing chamber (DMC) modes. This study aimed to evaluate the reliability and validity of the K5 in BBB and DMC at low, moderate, and high metabolic rates.

Interference of mouth breathing with orthodontic treatment duration in Angle Class II, Division 1

Revista de Odontologia da UNESP
Introduction Several factors can interfere with orthodontic treatment, and it is important to verify which ones may hinder its success. Objective To compare the duration of orthodontic treatment between nasal and mouth breathers with Angle Class II ...

Beyond-mean-field analysis of the Townes soliton and its breathing mode

SciPost Physics
By using the Bogoliubov perturbation theory we describe the self-bound ground state and excited breathing states of $N$ two-dimensional bosons with zero-range attractive interactions.

Effect of Oral Versus Nasal Breathing on Muscular Performance, Muscle Oxygenation, and Post-Exercise Recovery

Sports
Nitric oxide (NO) plays a crucial role in muscle oxidative capacity, which predicts muscle strength. This study aimed to investigate whether different breathing techniques (nasal or oral breathing) affect muscle performance during acute exhaustive ...

Time-Resolved Wall Ion Flux Linked to Discharge Current Oscillations in an SPT-100-Type Electric Thruster

Sakarya University Journal of Computer and Information Sciences
An SPT-100-type electric thruster is simulated at nominal operating conditions using a two-dimensional, axisymmetric, fully kinetic particle-in-cell/Monte Carlo collision (PIC/MCC) plasma model.

Nonlinear breathing modes at a defect [PDF]

, 2004
Recent molecular dynamics (MD) simulations of Cubero et al (1999) ofa DNA duplex containing the 'rogue' base difluorotoluene (F) in place of athymine (T) base show that breathing events can occur on the nanosecondtimescale, whereas breathing events in a normal DNA duplex take place on the microsecond timescale.The main aim of this paper is to analyse a
