The article deals with life support systems, the main purpose of such systems is to make building suitable for human life, or create comfortable conditions work. To a favorable environment, optimal temperature and humidity in all residential industrial premises, ventilation air conditioning are used. goal work was development high-tech energy-saving system modern automated control system. At sa...

background : since the use of high concentrations of oxygen in infants may lead to chronic lung problems, using proper methods of care in infants under mechanical ventilation is one of the most important measures in nicu. this study aimed to investigate the effects of prone and supine positions on oxygenation (spo 2 ) in premature infants under mechanical ventilation and comparing infants’ oxyg...

BACKGROUND Spontaneous ventilation, mechanical controlled ventilation, apneic intermittent ventilation, and jet ventilation are commonly used during interventional suspension microlaryngoscopy. The aim of this study was to investigate specific complications of each technique, with special emphasis on transtracheal and transglottal jet ventilation. METHODS The authors performed a retrospective...

for the past 3 decades, creating industrial clusters have been considered as an approach for the development of most small and medium enterprises. the goal of this programme is that all small and medium enterprises locating in a certain geoghraphic area can concentrate on cluster approach to collaborate in market research, production design, training and other activities that are not economical...

Recently, many studies have focused on studying indoor air quality, especially with the outbreak of COVID-19, which is one reasons for increased need to improve quality. Many ideas and applications are available incorporate nature into buildings quality (IAQ) thus secure a higher percentage natural ventilation pollution reduction. One these use "breathing walls" (BWs), envelope components based...

background: nasal intermittent positive pressure ventilation (nippv) is a non-invasive ventilatory mode, which delivers mechanical ventilation via nasal tubes or prongs. the present study was conducted to compare the efficacy of nippv and nasal continuous positive airway pressure ventilation (ncpap) in reducing the need for intubation in preterm infants with respiratory distress syndrome (rds)....

Industrial clusters have received considerable attention from economists and industrial analysts. The main purpose of this paper is to contribute to the understanding of the driving forces behind the growth of industrial clusters. Another core viewpoint anchored in this paper is that national competitive advantages can be achieved by industrial clusters. We examine the impacts of and determine ...

Abstract— In this paper, we report theoretical channel capacity estimates of heating, ventilation, and air-conditioning (HVAC) ducts based on multi-carrier transmission that uses M-QAM modulation and measured channel responses at 2.4 GHz Industrial, Scientific, and Medical (ISM) band. It is shown that, data rates in excess of 1 Gbps are possible over distances up to 500 m in “matched” ducts (on...

Biological indicators of exposure to solvents are often characterised by a high variability that may be due either to fluctuations in exposure or individual differences in the workers. To describe and understand this variability better a physiological model for differing workers under variable industrial environments has been developed. Standard statistical distributions are used to simulate va...
