Sir,—I refer to the recent review by Phillips, Daborn and Hatch [1]. Between 1991 and 1993 the Department of Anaesthetics in Newcastle examined the problem of preoperative fasting intervals for children presenting for routine surgery. An initial audit revealed that many children were undergoing prolonged fasts before anaesthesia. After reviewing the literature [2], 8 clear fluid fast of 2 h was...

This study tested the effects of lane width, lane position and edge shoulder width on driving behavior for a three-lane underground urban expressway. A driving simulator was used with 24 volunteer test subjects. Five lane widths (2.85, 3.00, 3.25, 3.50, and 3.75 m) and three shoulder widths (0.50, 0.75, and 1.00 m) were studied. Driving speed, lane deviation and subjective perception of driving...

in this paper, an analytical method called the parametric iteration method (pim) is presented for solving the second-order singular ivps of lane-emden type, and its local convergence is discussed. since it is often useful to have an approximate analytical solution to describe the lane-emden type equa- tions, especially for ones where the closed-form solutions do not exist at all, therefore, an ...

This papaer proposes a method of estimating the state of a driving lane by using a multiple-model particle filter for switching the type of multiple-lane model. This model represents whether there is a lane to the left or right of the running lane or there are lanes on both sides of the running lane. Using the context that an image is captured by car-mounted camera, we simplified the lane detec...

Lane and Terry (2000) defined mood as “a set of feelings, ephemeral in nature, varying in intensity and duration, and usually involving more than one emotion” (p.16). They proposed a conceptual framework for predicting performance from mood states assessed by the Profile of Mood States (McNair, Lorr, & Droppleman, 1971) or its derivatives. The conceptual model indicated that depressed mood infl...

Vehicle crashes are amongst the major causes of mortality and results in losses of lives and properties. A large number of the vehicle crashes occur on rural roads. Accidents become more noteworthy in two-lane roads due to going and coming traffic. Therefore, prediction of crashes and their causes are considerably important to reduce the number and severity of the accidents. The safety index is...

The concept of Ford’s lane keeping sys­ tem includes two variants: The driver can select a warning function and a lane keeping function in case the vehicle leaves its current lane, known as lane keeping alert, ❶, and lane keeping aid, ❷, respectively. Both functions make use of a camera serving as a sensor for iden­ tifying the traffic lane and the lane mark­ ings. Identifying the ve hicle’s ow...

The animals were subjected to hormone treatment for 1 week. Hormones were administered either continuously via osmotic minipumps (m.p.) or intermittently by subcutaneous injections once ( 1 x s.c.) or twice (2 x s.c.) daily. Daily doses were 120 pg for GH and 100 pg for methyltrienolone, respectively. Lane I , control female; lane 2, hypophysectomized (Hx) female; lane 3, female + androgen (met...
