OBJECTIVES Biologically variable ventilation improves lung function in acute respiratory distress models. If enhanced recruitment is responsible for these results, then biologically variable ventilation might promote distribution of exogenous surfactant to nonaerated areas. Our objectives were to confirm model predictions of enhanced recruitment with biologically variable ventilation using comp...

Samples of airborne particles with aerodynamic diameters smaller than 10 µm (PM10) were collected in 2021 at two households the Metropolitan Area Mexico City. Both sites are areas different characteristics (residential or industrial zones). Simultaneous sampling indoors and outdoors was carried out locations, using low-volume samplers. The study aimed to determine indoor outdoor gravimetric mas...

INTRODUCTION Independent lung ventilation is a form of protective ventilation strategy used in adult asymmetric acute lung injury, where the application of conventional mechanical ventilation can produce ventilator-induced lung injury and ventilation-perfusion mismatch. Only a few experiences have been published on the use of independent lung ventilation in newborn patients. CASE PRESENTATION...

The volatile organic compounds (VOCs) in the indoor air come from many sources including building materials, furnishings, occupant activities and in some cases, the ventilation air. Granular activated carbons (GAC) have been increasingly used to remove these contaminants, particularly for small commercial buildings and those located in urban centers or near industrial plants where the quality o...

Depending upon one's perspective, distributed control has had an either extremely long, or extremely short history in the application of heating, ventilation, and air-conditioning (HVAC) control. HVAC systems have been in existence for the entire duration of human architecture, at least in terms of heating, with air-conditioning arriving in the 1800's with the industrial revolution, as a means ...

Ventilative cooling technologies have the potential to be an effective measure reduce buildings energy consumption, by meeting some or all of requirement a building without need for mechanical cooling. Mixed-Mode (MM) utilise both natural and systems meet their thermal demand. These are able guarantee that comfort conditions maintained, whilst exploiting provided climate. Effective management i...

This case report describes the anesthetic management and ventilation technique in the surgical treatmentof traumatic diaphragmatic hernia in a dog. A 5-month-old 8-kg female terrier with a history of car accidentwas presented for femoral fracture repair. Before anesthetic induction, marked tachypnea and dyspnea werenoted. Diaphragmatic hernia was diagnosed based upon radiographic and ultrasonog...

A patient with bilateral multinodular bronchiolar carcinoma is described in whom carbon monoxide transfer factor and arterial oxygen saturation were greatly impaired but lung volumes and ventilation were only minimally reduced. We record this because we have not found previous reports of detailed pulmonary function studies in this condition. A 57-year-old man was admitted to hospital in August ...

In order to achieve interactive rates for the rendering of large industrial environments, it is necessary to reduce the complexity of the objects used such scenes. For objects representing piping, ventilation, etc. we use simple primitives which are tessellate at rendering time. We introduce an dynamic tessellation algorithm which adaptively controls the amount of polygons used to approximate t...

Existing detailed simulation methods generally address the energy use of individual buildings, through the specification of its fabric, ventilation, fuelled services and occupancy patterns. Current concerns in developing sustainable built environments however often focus on groups or communities of buildings. In the Virtual Village (VIRVIL) project, means of extending detailed simulation method...
