Alveolar Gas Mixing in Chronic Pulmonary Hyperinflation
1991
It is well known that in chronic pulmonary hyperinflation defects in intrapulmo-nary gas mixing and in V/Q ratio are likely to occur.
O-45 The influence of training program on the functionality of respiratory system
2016
For each individual must be appropriate life style modelling of the respiratory system functionality as well necessity for physical activity, training program, especially for amateur and professional athletes. The influence of variable factors gives implications to the amateur athletes’ body and respiratory system- health condition, supplements or necessary treatment, physical working capacity of the body, physical activity with increased function of respiratory system, cardiopulmonary interdependence, hydration, fitness level, physical abilities, training or competition period, training process and ambience. High level functionality of respiratory system decreases risk of potential interac…
Developmental trends in children's pretend play.
1991
The developmental trends in pretend play were investigated in children 2-6 years of age (18 in each of five age groups) by examining changes in pretend action and speech separately. Play behaviour was assessed by using a selected set of Duplo Lego toys. Interest focused on occurrence of decentration, decontextualization and integration at different age levels. The proportions of decentred and decontextualized acts, action integrations and play themes, increased linearly with age. Changes in substitutive and inventive actions were, however, more minor than expected. Single-scheme combinations did not reveal any essential aspect of the development of children's symbolic competence. In this se…
Cubic smoothing splines background correction in on-line liquid chromatography–Fourier transform infrared spectrometry
2010
A background correction method for the on-line coupling of gradient liquid chromatography and Fourier transform infrared spectrometry (LC-FTIR) is proposed. The developed approach applies univariate background correction to each variable (i.e. each wave number) individually. Spectra measured in the region before and after each peak cluster are used as knots to model the variation of the eluent absorption intensity with time using cubic smoothing splines (CSS) functions. The new approach has been successfully tested on simulated as well as on real data sets obtained from injections of standard mixtures of polyethylene glycols with four different molecular weights in methanol:water, 2-propano…
Mythical Creatures, the Making of Wearing Apparel, and the Landscape
2011
Stones where mythical creatures carry out work connected with wearing apparel appear in publications on the mythological stones of Lithuania and Belarus. This theme is not so widely considered in Latvian research literature. The aim of this work is to show that in Latvian folklore, by natural (stone, tree, stump, water, cave, etc) and man-made objects of the cultural space (threshing barn, cemetery, hill-fort, etc), mythical creatures tailor, spin, knit and mend for people or for themselves.

Metallic artefacts from Monte Molião (Lagos, Portugal) : the roman clothing elements
2020
As escavações arqueológicas levadas a efeito em Monte Molião permitiram recolher um conjunto muito significativo de artefactos metálicos, diversificados cronológica e funcionalmente, entre os quais se destacam os elementos de indumentária. Trata-se de fíbulas, de botões e de fechos de cinturão que pertencem à época romana, ocupação bem caracterizada no sítio através de sequências estratigráficas claras, que foram tidas em consideração na abordagem a estes materiais concretos.
A filtering algorithm for maneuvering target tracking based on smoothing spline fitting
2014
Published version of an article in the journal: Abstract and Applied Analysis. Also available from the publisher at: http://dx.doi.org/10.1155/2014/127643 Open Access Maneuvering target tracking is a challenge. Target's sudden speed or direction changing would make the common filtering tracker divergence. To improve the accuracy of maneuvering target tracking, we propose a tracking algorithm based on spline fitting. Curve fitting, based on historical point trace, reflects the mobility information. The innovation of this paper is assuming that there is no dynamic motion model, and prediction is only based on the curve fitting over the measured data. Monte Carlo simulation results show that, …
The AVL-mode: a safe closed loop algorithm for ventilation during total intravenous anesthesia.
1994
The Adaptive Lung Ventilation Controller (ALV-Controller) represents a new approach to closed loop control of ventilation. It is based on a pressure controlled ventilation mode. Adaptive lung ventilation signifies automatic breath by breath adaptation of breathing patterns to the lung mechanics of an individual patient. The specific goals are to minimize work of breathing, to maintain a preset alveolar ventilation and to prevent the occurrence of intrinsic PEEP. We ventilated 5 patients undergoing major abdominal procedures using ALV. ALV was tolerated well in all patients. Alveolar ventilation was preset between 5500 and 6500 ml/min. Serial dead space (Vds) and respiratory time constant (r…
Successful treatment of a patient with ARDS after pneumonectomy using high-frequency oscillatory ventilation.
1999
High frequency oscillatory ventilation (HFOV) was used in a patient who developed the acute respiratory distress syndrome 5 days following a right pneumonectomy for bronchogenic carcinoma. When conventional pressure-controlled ventilation failed to maintain adequate oxygenation, HFOV dramatically improved oxygenation within the first few hours of therapy. Pulmonary function and gas exchange recovered during a 10-day period of HFOV. No negative side effects were observed. Early use of HFOV may be a beneficial ventilation strategy for adults with acute pulmonary failure, even in the postoperative period after lung resection.
Dynamic computed tomography: a novel technique to study lung aeration and atelectasis formation during experimental CPR
2002
Objective: To develop an image based technique to study the effect of different ventilatory strategies on lung ventilation and alveolar recruitment during cardiopulmonary resuscitation (CPR). Design: (1) Technical development of the following components: (a) construction of an external chest compression device, which does not interfere with CT imaging, and (b) development of a software tool to detect lung parenchyma automatically and to calculate radiological density parameters. (2) Feasibility studies: three strategies of CPR ventilation were performed and imaged in one animal each (pigs, 25 kg): volume-constant ventilation (VCV), no ventilation, or continuous airway pressure (CPAP). One m…
