[1] Emission inventories of air pollutants are crucial information for policy makers and form important input data for air quality models. Using satellite observations for emission estimates has important advantages over bottom-up emission inventories: they are spatially consistent, have high temporal resolution, and enable updates shortly after the satellite data become available. We present a...

Because of its physiological importance in the rapid growth rate of birds and the continous air flow that provided it the lungs in both inspiration and expiration, the present study was performed to examine the air sac system on twelve mature turkeys of both sexes and different weight . Seven air sacs were demonstrated associated with the two lungs and characteristic for the turkey. They compri...

[1] Estuarine near‐surface turbulence is important for transport, mixing, and air‐water exchanges of many important constituents but has rarely been studied in detail. Here, we analyze a unique set of estuarine observations of in situ atmospheric and full water column measurements, estimated air‐sea exchanges, and acoustic measurements of several terms in the turbulent kinetic energy (TKE) budg...

1. An ultracentrifuge is described in which the rotor is driven by a compressed air turbine, and is spun in an evacuated chamber to minimize friction and heating. The rotating parts are supported by a cushion of air in an air bearing. 2. The centrifuge rotor holds 10 test tubes inclined at 45 degrees to the axis, and has a capacity of 55 cc. It is operated at a maximum speed of 51,000 R.P.M., w...

Abstract Bubble column is a commonly used multiphase reactor. Owing to the complicated nature of its flow structure, computational fluid dynamics has frequently been as useful instrument for studying mechanics in bubble column. However, most previously studied systems are air-water system, while air-nitric acid solution system rarely reported. In present study, differences size distribution pur...

In this paper we present a case study of a record low ozone event observed over the UK in January 2006. We focus on the dynamical processes that cause this event. This is done by examining the observations, meteorological analyses and back trajectories calculated by the NAME III atmospheric dispersion model. We show that this model, hitherto only used for tropospheric pollution studies, can be ...

Aim: SARS-CoV-2 infection frequently affects the lungs, it can also cause severe inflammation in lower respiratory tract, leading to tracheal damage. We aimed investigate relationship between mean air column and COVID-19.Material Method: Chest computed tomography scans of COVID-19 patients treated an intensive care unit June 1st, 2020 October 1st 2022 were retrospectively evaluated. The area tr...
