China has a wide territory and different climates that will impact on the energy-saving rate of variable-air-volume system.
To help the engineers have a good idea of the rate of return of variable-air-volume system in different areas of China, it is necessary to establish such program that can evaluate the energy-saving rate of variable-air-volume system compared to constant-air-volume system and fan-coil system.
Since both studies used data from computerised General Practice records [The Health Improvement Network THINN) database and QResearch database] rather than self-reported data, the true rate of variables such as falls may have been underestimated.
This allows specification of the substitution rates of variable sites, independently of the proportion of invariable sites.
The Euclidean distance between the sliding data window and the optimal evaluation level is employed to measure the contribution rates of variables, which indicate the possible reason for the non-optimal operating performance.
Measure prevalence rates of variables representing well-being among youth residing in an Israeli boarding school.
The aims of this study are to: Measure prevalence rates of variables representing well-being among youth residing in an Israeli boarding school.
The positive rates of variables measured in peripheral blood in all of the methods were too low to help diagnose acute pulmonary HCMV infection (Additional file 1: Table S8).
However, there's a £25 annual fee on the card, in addition to a representative rate of 14 per cent (variable) on purchases if you don't clear your balance.
The response rate of the variable income per capita was low (69.7%).
