- artificial lung ventilation, pressure controlled modes, and automatic proportional minute ventilation
- Language:
- English
- Description:
- The main goal of our prospective randomized study was comparing compare the effectiveness of ventilation control method „Automatic proportional minute ventilation (APMV) “versus manually set pressure control ventilation modes in relationship to lung mechanics and gas exchange. 80 patients undergoing coronary artery bypass grafting (CABG) were randomized into 2 groups. 40 patients in the first group No. 1 (APMV group) were ventilated with pressure control (PCV) or pressure support ventilation (PSV) mode with APMV control. The other 40 patients (control group No.2) were ventilated with synchronized intermittent mandatory ventilation (SIMV-p) or pressure control modes (PCV) without APMV. Ventilation control with APMV was able to maintain minute ventilation more precisely in comparison with manual control (p<0.01), similarly deviations of ETCO2 were significantly lower (p<0.01). The number of manual corrections of ventilation settings was significantly lower when APMV was used (p<0.01). The differences in lung mechanics and hemodynamics were not statistically significant. Ventilation using APMV is more precise in maintaining minute ventilation and gas exchange compared with manual settings. It required less staff intervention, while respiratory system mechanics and hemodynamics are comparable. APMV showed as effective and safe method applicable on top of all pressure control ventilation modes.

4. Snake-like, crawling technological robots for the operation inside pipelines
- Creator:
- Bashkarev, Albert, Maslov, Vladimir, Sedler, Mikhail, and Sedler, Maria

- Type:
- model:article and TEXT
- Subject:
- technological robot for pipelines, snake-like, autonomous robot, and designing calculation
- Language:
- English
- Description:
- Robots for automatic motion inside pipelines of various diameters from 100 up to 1000 mm, having essentially different geometrical parameters (radiuses and a configuration of bending, length, etc.) and transporting the various environment (gas, oil, water, etc.) is the modern direction of an application robotics, very demanded by the industry. This paper presents some examples of such robots intended for execution of various technological operations, diagnostics, repairing, clearing, welding, etc. One of the most complex operations is the painting demanding heightened smoothness of the robot motion. Paper introduces new approaches in design and calculations of this robotic system. and Obsahuje seznam literatury

5. Susceptibility of IFN-γ or IL-12 knock-out and SCID mice to infection with two microsporidian species, Encephalitozoon cuniculi and E. intestinalis

- Type:
- model:article and TEXT
- Subject:
- Microsporidia, Encephalitozoon intestinalis, Encephalitozoon cuniculi, IFN-γ knock-out, IL-12 knock-out, and SCID mice
- Language:
- English
- Description:
- Susceptibility of three strains of immunodeficient mice to two related microsporidian species Encephalitozoon cuniculi Levaditi, Nicolau et Schoen, 1923 and Encephalitozoon intestinalis (Cali, Kotler et Orenstein, 1993) was compared. While both, severe combined immunodeficient (SCID) and interferon-gamma knock-out (IFN-γ KO) mice, succumbed to either intraperitoneal (i.p.) or peroral (p.o.) (natural) infection with both parasites, only i.p. infection with E. cuniculi killed interleukin-12 knock-out (IL-12 KO) mice. IFN-γ KO mice died earlier than SCID mice. Adoptive transfer of naive splenocytes from IFN-γ KO mice did not protect the SCID mice from a lethal infection with either of the Encephalitozoon species. However, reconstituted mice survived significantly longer (P<0.05), thus indicating the role of IFN-γ produced by host NK cells in the development of mechanisms of anti-microsporidial protective immunity. Non-lethal outcome of the infection always correlated with the increase in CD8+ T lymphocyte subpopulation. Both E. intestinalis-infected IFN-γ KO and IL-12 KO mice produced comparable levels of specific antibodies, suggesting that antibodies did not protect IFN-γ KO mice from lethal infection.

6. The personite problem and the stage-theoretic reply
- Creator:
- Noonan, Harold
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- personites, perdurance, stage-theory, moral status, and Johnston
- Language:
- Slovak
- Description:
- Personites are shorter-lived, person-like things that extend across part of a person’s life. Their existence follows from the standard perdurance view of persons. Johnston argues that it has bizarre moral consequences. For example, it renders morally problematic spending time learning a difficult language in anticipation of going abroad. The crucial thought is that if persons have moral status so do personites. Johnston argues for this claim. Kaiserman responds, on behalf of stage theory, that this only works on a perdurantist account. This is a conservative response to the problem. It seeks to show that retaining the ontology of perdurantism one can resolve the difficulty by a semantic change. I show that the personite problem can be reworked as an argument against stage theorists. The stage theorist can respond by rejecting an assumption of the reasoning. But if it is acceptable for him to do so the perdurantist can reject this assumption too, which is enough by itself to block Johnston’s argument. Thus, for all it helps with the personite problem, stage theorists might as well be perdurantists.
