Abstract:

This thesis explores the relationship between inhalation amplitude and turn-taking in spontaneous multiparty conversations held in Estonian. Respiratory activity is recorded with Respiratory Inductance Plethysmography. The main focus is on how inhalation amplitude varies between the inhalations produced directly before turn onset compared to the following inhalations within the same speaking turn. The results indicate a significant difference in amplitude, realised mainly by an increase in inhalation end lung volume values. One of the possible functions of this pattern is to signal an intentio

Abstract:

When spontaneous breathing (SB) is allowed during mechanical ventilation (MV), atelectatic lung areas are recruited and oxygenation improves thereby. Whether unsupported SB at its natural pattern (without PEEP and at low pressure/small tidal volume) equally recruits and improves oxygenation, and if so by which mechanism, has not been studied. A porcine lung collapse model was designed to study this question. The cardiac output dependency of the pulmonary shunt was investigated with healthy lungs and with major shunt (during one-lung ventilation) and with SB, MV and continuous positive airway p

Abstract:

Two important areas of physics are spontaneous pattern formation and droplet motion on surfaces. These two areas can be brought together since the texture of a surface can influence its wetting properties. Therefore by controlling the factors that determine the length scales of the patterns during spontaneous pattern formation, it is possible to design surfaces with very specific wetting properties. This was used to create surfaces that could direct the motion of sessile water droplets. Patterned surfaces with micro-wrinkled surface structures were prepared by thermally evaporating thin Alumin

Abstract:

Analysis of breathing pattern can quantify parameters of breathing such as rate, volume, timing and regularity/rhythmicity. This information can be useful to compare breathing patterns in those healthy and with disease, under different experiment conditions (such as rest versus activity) and to monitor changes over time. In this research, respiratory inductive plethysmography (RIP) was used to record breathing patterns in a group of healthy subjects and a group of severe asthma patients. RIP is a leading technology for ambulatory monitoring of breathing, but traditional RIP devices suffered fr

Abstract:

The seminal work published by Alan Turing in 1952 provides the framework for our understanding of spontaneous pattern emergence in Nature. He proposed that when a reaction-diffusion system’s uniform states become sufficiently stressed, arbitrarily-small disturbances combined with inherent feedback processes can lead to spontaneous self-organization into finite-amplitude patterns with a single dominant scalelength. In this thesis, Turing’s universal mechanism is applied to a range of distinct nonlinear optical cavities. Of principal interest is a Fabry-Pérot (FP) resonator, which comprises a th

Abstract:

BACKGROUND: Aerosol therapy using albuterol is one of the most prescribed asthma treatments. The most frequently used methods of aerosol delivery are pneumatic jet nebulizer (JN), pressurized metered-dose inhaler (pMDI), and breath-actuated nebulizer (BAN). Choosing among these devices is usually not based on thorough comparison of efficiency or cost. We compare the efficiency of these three devices using a spontaneously breathing adult model. METHODS: We connected each aerosol generator—JN, BAN, or pMDI with a valved holding chamber (VHC)—to the face of an adult teaching manikin. Below the b

Abstract:

During entrance into hibernation in mammals, continuous breathing is converted to intermittent breathing in conjunction with the reductions in metabolic rate (MR) and body temperature (T[sub B]). The intermittent breathing pattern is characterized by long non-ventilatory periods (T[sub NVP]) , which are interrupted by bursts of several breaths (Cheyne-Stokes respiration, CSR) in some species, or by only single breaths in other species. The nature of this species difference in intermittent breathing pattern has remained a puzzle, due mainly to the problems of measuring ventilation accurately in

Abstract:

Swallowing is an essential motor act that coordinates the movement of food or saliva from the mouth through the pharynx and into the esophagus while protecting the upper airways from aspiration of those materials. Disordered swallowing, or dysphagia, results when bolus movement from the oropharyngeal phase into the esophageal phase is uncoordinated. Dysphagia directly causes or increases the risk of aspiration during swallowing in many clinical pathologies including Parkinson’s disease, Alzheimer’s disease, cerebrovascular incidents (stroke) in addition to being prevalent among the elderly pop

Abstract:

This dissertation investigates the mechanisms underlying pattern separation, using rodent models and behavioural tasks that assess the use of representations for similar stimuli. Pattern separation is a theoretical mechanism involving the transformation of inputs into output representations that are less correlated to each other. Because of this orthogonalizing process, similar experiences are stored as discrete non-overlapping representations. Studying pattern separation emphasizes the important but often overlooked fact that successful memory involves more than just remembering events over a

Abstract:

Population-wide synchronized rhythmic bursts of electrical activity are present in a variety of neural circuits. The proposed general mechanisms for rhythmogenesis are often attributed to intrinsic and synaptic properties. For example, the recurrent excitation through excitatory synaptic connections determines burst initiation, and the slower kinetics of ionic currents or synaptic depression results in burst termination. In such theories, a slow recovery process is essential for the slow dynamics associated with bursting. This thesis presents a new hypothesis that depends on the connecti

Abstract:

La tomographie par émission de positons (TEP) est une méthode d'imagerie clinique en forte expansion dans le domaine de l'oncologie. De nombreuses études cliniques montrent que la TEP permet, d'une part de diagnostiquer et caractériser les lésions cancéreuses à des stades plus précoces que l'imagerie anatomique conventionnelle, et d'autre part d'évaluer plus rapidement la réponse au traitement. Le raccourcissement du cycle comprenant le diagnostic, la thérapie, le suivi et la réorientation thérapeutiques contribue à augmenter le pronostic vital du patient et maîtriser les coûts de santé.

Abstract:

L’insuffisance respiratoire chronique est un syndrome défini par une défaillance monoviscéralerespiratoire. Sa principale origine est aujourd’hui le syndrome obésité-hypoventilation qui concerne 4 à 5% des patients obèses. L’IRC est aussi le stade évolutif terminal de la bronchopneumopathie chronique obstructive qui touche 6 à 8% de la population adulte. L’incidence de ces pathologies et donc de l’insuffisance respiratoire est en augmentation constante. Dans cette thèse, nous avons évalué les nouvelles modalités diagnostiques et thérapeutiques qui pourraient améliorer la prise en charge des pa

However, these parameters have their intrinsic limitations when applied to clinical applications such as the physiological adaptation control. Therefore, this thesis was aimed at identifying the differentiation between spontaneous breathing and compulsive breathing using electromyogram (EMG) signals to improve the schedule of lung ventilators.

Spontaneous breathing trial (SBT) is the most common method used to evaluate patients’ ability to breathe by themselves and plays an important role in decision making for weaning. The aim of our study was to investigate the effect of different methods of SBT in respiratory care unit (RCU) patients with atrial fibrillation (AF) on weaning outcome Methods: We retrospectively analyzed different methods of SBT in pat

We calculated the fractal dimension of the optical patterns generated by optical modulation instability (MI). By calculating the fractal dimension, we found that at low intensity threshold, MI patterns can be regard as fractals due to its self-similar structure. We also found that as the voltage applied to the nonlinear crystal increases, the fractal dimension decreases. The decreasing rate is equal among different laser beam intensity. Finally, we found that the f

In physiology, these environmental changes are so called “stress ”. This stress would change the equilibrium states of human bodies and result in physiological reactions. These could generally be sorted out into two classes: one is emergency conditions, which could deal with emergency conditions so that individuals could be self-protected; the other is physiologic reaction under long-term stress.
