Firstly, a maximum permissible airflow of 25 m3/s across the longwall coalface could only dilute a maximum gas inflow of 0.37 m3/s (22.2 m3/min), despite a relaxation by the mining authority which raised the maximum permitted methane concentration from 1.0% to 1.5% (a reduction in factor of safety from 5.0 to 3.3). (...) The second constraint was the airway into which the district ventilation air was to discharge, in which a maximum of 1% methane is permitted. Solution: A Y-ventilation system (Figure 1) was designed to introduce a further 50 m3/s of air and add to the 25 m3/s passing across the face, the combined flow passing behind the face diluting the methane emitted from the coalface and the goaf.

AMENDMENT TO ANNEX 1, APPENDIX 2 PARAGRAPH 3.2.6 AND 4.3.4 (II), ANNEX 1, APPENDIX 3 AND THE ATP HANDBOOK
Currently there is no airflow requirement despite the secondary coolant being vital for safe carriage of perishable cargoes in mechanically refrigerated vehicles. 2. (...) A UK proposal (ECE/TRANS/WP11/2012/5) was to change the wording regarding airflow tests was presented at the 68th session. This was not accepted, as verifying manufacturers’ airflow figures is not mandated. (...) If the equipment internal volume is ≥100m3 or ≤2 m3, the competent authority where the equipment is registered or recorded shall determine adequate airflow based on the overall heat transfer and where they are permitted to operate.”

Inspection Palpation and percussion Auscultation Measurement of Airflow Limitation . . . . . . . . . . . . . . . . (...) It is also important to recognize that cough and sputum production may precede the development of airflow limitation; conversely, some patients develop significant airflow limitation without chronic cough and sputum production. (...) Although COPD is defined on the basis of airflow limitation, in practice the decision to seek medical help (and so permit the diagnosis to be made) is normally determined by the impact of a particular symptom on a patient's lifestyle.

On the vertical tail, NASA and Boeing tested active flow control to improve airflow over the rudder and maximize aerodynamic efficiency. (...) On the 757’s right wing, NASA and Boeing tested “bug phobic” coatings that can reduce aerodynamic drag from insect residue, enabling more laminar flow by smoothing the airflow on the surface of the wing. Except for Boeing proprietary technology, NASA knowledge gained in collaboration with Boeing from ecoDemonstrator research will be publicly available to benefit the industry.

TRANS/WP.11/2002/6 page 4 6.2.3 Blocking the defrosting cycles In order to ensure that defrosting will not interfere with the first six hours of the test, one of the following methods may be used: disconnection of the defrosting programming clock; or programming of the command system so that the first defrosting will take place after six hours have elapsed; or disconnection of the sensor fixed to the evaporator which permits defrosting by closing the contact. 6.2.4 Location of the temperature sensors The temperature sensors shall be disposed as follows: One sensor on the blower of each evaporator; One sensor on the return airflow of each evaporator; One sensor outside the body, at mid-height in the middle of one side; One sensor outside the body in its rear section. (...) Where there are several evaporators, all the return airflow sensors must have reached the class temperature limit. (...) Model or prototype means equipment which, after testing in a laboratory recognized by ATP and certification by the issue of a test report, will permit the approval of new equipment mass produced according to the model.

Chronic Obstructive Pulmonary Disease (COPD) • COPD is a disease state characterized by airflow limitation that is not fully reversible. The airflow limitation is usually both progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases. • The main cause for developing COPD is tobacco smoking. (...) Asthma • Asthma is a chronic inflammatory disorder of the airways including an airflow limitation, which is usually reversible. It affects children and adults of all ages. Chronically-inflammed airways are hyperresponsive; they become obstructed and airflow is limited (by bronchoconstriction, mucus plugs and increased inflammation) when airways are exposed to various risk factors. • Common risk factors include allergens such as domestic dust mites, animals with fur, cockroaches, pollens and moulds, occupational irritants, tobacco smoke, air pollution.
