THE variation of full throttle engine brake horsepower with altitude at constant rotational speed is a matter of great importance to aircraft designers and those concerned with the measurement of aircraft performance. For the former its main importance probably lies in the design of aeroplanes intended...

whereCpis the specific heat capacity of air at constant pressure, andhis the altitude. The gravity wave Ep is calculated using Eq. (4). The Ep depends only on the raw temperature profile, which can be separated into the background temperature (T), and the temperature fluctuation (\(T{\pr...
(100–2200 m above sea level) via a complete census of all trees having ≥ 10 cm diameter at breast height in ten one-hectare permanent sampling plots. The numbers of tree families, genera and species and community-scale tree diversity decreased with increasing altitude. Tree diversity, ...
relationship with productivity (total height). The adaptive value of the GV and PP of shoot growth traits could allowP. pseudostrobuspopulations to mitigate the negative impacts of environmental fluctuations associated with global warming and provide competitive advantages in productivity for domestication ...
were women. Of the 117 studies with data on glycemic variables, 113 (97%) with 351,270 participants (96% of all participants) also had data on body-mass index (BMI); the remaining four studies either did not collect anthropometric information or only had self-reported height and weight ...
Stratosperic sulfuric acid vapour concentrations have been measured in the altitude region from 23.5 to 33 km by the passive chemoionisation mass spectrometry method (PACIMS), in recent years sucessfully introduced by our group for stratospheric trace gas detection. The data agree with current model...
(usually represented by height); account may, however, also need to be taken of ethnic differences, the posture of the subject or the time of day when the test was performed. For information on the commonly used equations the reader is referred to the detailed account in the classic text ...
Day-to-day variation in the altitude of bottomside F-layer is also seen. From comparison with the peak PRE, it is found that the F2 peak and bottomside altitudes ascend and the electron density at the F2 peak altitude decreases when the peak PRE is intense (Fig. 2a, b). In Fig. 2...
