based on the detected value of the tank pressure and the canister pressure.
The principle for performing testing of the sealing in the tank side will now be described. When fuel vaporizes in the tank 81 with the control valve 90 in a closed state, the tank side pressure exceeds a predetermined reference value. Holes such as punctures in the vapor line 83 would inhibit the tank side pressure from exceeding the predetermined reference value. Therefore, it is possible to test the tank side sealing by having the ECU 86 judge whether the tank side pressure, detected by the pressure sensor 88, exceeds the reference value.
When the vehicle is moving, the running state of the vehicle or the condition of the road surface causes the fuel in the tankInfluence of parents' oral health behaviour on oral health status of their school children: an exploratory study employing a causal modelling technique.
The aim of this study was to examine the simultaneous interrelationships between parents' oral health behaviour and the oral health status of their school children. Subjects comprised 296 pairs of parents (mother or father) and their children at an elementary school in Hiroshima. The child's dental examination was performed using the World Health Organization (WHO) caries diagnostic criteria for decayed teeth (DT) and filled teeth (FT). The Oral Rating Index for Children (ORI-C) was used for the child's gingival health examination. Hiroshima University Dental Behavioural Inventory (HU-DBI) was used for the assessment of the parents' oral health behaviour. A parent-child behavioural model was tested by the linear
