Fire risk assessment of a health care facility

Статья посвящена расчету величины индивидуального пожарного риска на объекте защиты санаторий-профилакторий ТПУ. Производился анализ причин пожаров в учреждениях здравоохранения, а также расчет индивидуального пожарного риска на объекте защиты санаторий-профилакторий ТПУ и сопоставление расчетных величин с нормативным значением пожарного риска. Приведены мероприятия по снижению вероятности возникновения пожара и повышению проводимых работ по техническому обслуживанию и планово-предупредительному ремонту систем противопожарной защиты АПС, СОУЭ в санатории-профилактории ТПУ.The article is devoted to calculating the value of individual fire risk at the object of protection of the sanatorium-preventorium of TPU. The analysis of the causes of fires in health care institutions, as well as the calculation of individual fire risk at the object of protection of the sanatorium-preventorium of TPU and comparison of the calculated values with the standard value of fire risk. Measures are given to reduce the probability of fire and increase the ongoing maintenance and scheduled preventive repair of fire protection systems APS, SSE in the sanatorium-preventorium of TPU

Dynamics of tidal synchronization and orbit circularization of celestial bodies

PACS number s : 05.45.Xt, 05.45.Gg, 95.10.Ce, 96.15.DeWe take a dynamical-systems approach to study the qualitative dynamical aspects of the tidal locking of the rotation of secondary celestial bodies with their orbital motion around the primary. We introduce a minimal model including the essential features of gravitationally induced elastic deformation and tidal dissipation that demonstrates the details of the energy transfer between the orbital and rotovibrational degrees of freedom. Despite its simplicity, our model can account for both synchronization into the 1:1 spin-orbit resonance and the circularization of the orbit as the only true asymptotic attractors, together with the existence of relatively long-lived metastable orbits with the secondary in p:q synchronous rotationWe acknowledge projects OTKA T72037 Hungary , Hielocris Spain , the Human Frontier Science Program I.T. , MCI project CGL-2008-06245-C02-02 Spain , and the Spanish-Hungarian Binational project TeT ESP-34/2006.Peer reviewe

The use of the Airtraq® optical laryngoscope for routine tracheal intubation in high-risk cardio-surgical patients

<p>Abstract</p> <p>Background</p> <p>The Airtraq^®optical laryngoscope (Prodol Ltd., Vizcaya, Spain) is a novel disposable device facilitating tracheal intubation in routine and difficult airway patients. No data investigating routine tracheal intubation using the Airtaq^®in patients at a high cardiac risk are available at present. Purpose of this study was to investigate the feasibility and hemodynamic implications of tracheal intubation with the Aitraq^®optical laryngoscope, in high-risk cardio-surgical patients.</p> <p>Methods</p> <p>123 consecutive ASA III patients undergoing elective coronary artery bypass grafting were routinely intubated with the Airtraq^®laryngoscope. Induction of anesthesia was standardized according to our institutional protocol. All tracheal intubations were performed by six anesthetists trained in the use of the Airtraq^®prior.</p> <p>Results</p> <p>Overall success rate was 100% (n = 123). All but five patients trachea could be intubated in the first attempt (95,9%). 5 patients were intubated in a 2nd (n = 4) or 3rd (n = 1) attempt. Mean intubation time was 24.3 s (range 16-128 s). Heart rate, arterial blood pressure and SpO₂were not significantly altered. Minor complications were observed in 6 patients (4,8%), i.e. two lesions of the lips and four minor superficial mucosal bleedings. Intubation duration (p = 0.62) and number of attempts (p = 0.26) were independent from BMI and Mallampati score.</p> <p>Conclusion</p> <p>Tracheal intubation with the Airtraq^®optical laryngoscope was feasible, save and easy to perform in high-risk patients undergoing cardiac surgery. In all patients, a sufficient view on the vocal cords could be obtained, independent from BMI and preoperative Mallampati score.</p> <p>Trial Registration</p> <p>DRKS 00003230</p
