Two experiments investigated the effects of system response time (SRT) on navigating through hypertext. SRT duration was varied systematically and manipulated between subjects. The dependent variables were residence time, emotional strain, and memory performance. All three variables were influenced by SRT. As a prominent result, a synchronization between computer’s and human’s response time was...

Background and Objectives: Chicken pox has potential complications during pregnancy for both the mother and her baby. The aim of this study was to determine the Varicella-zoster virus (VZV) immune status in pregnant women in Babol and its surrounding neighborhoods. Materials and Methods: This seroepidemiological study was carried out on 427 pregnant women referred to Rohani Hospital, Babol, no...

The residence time of a single dye molecule diffusing within a laser spot is propotional to the total number of photons emitted by it. With this application in mind, we solve the spherically symmetric "residence time equation" (RTE) to obtain the solution for the Laplace transform of the mean residence time (MRT) within a d-dimensional ball, as a function of the initial location of the particle...

Professional programmers need common coding conventions to assure co-operation and a degree of quality of the software. Novice programmers, however, easily forget issues of programming style in their programming coursework. In particular with large classes, students may pass several courses without learning elements of programming style. This is often due to shortage of tutor work to give stude...

BACKGROUND AND AIMS Leaf longevity is controlled by the light gradient in the canopy and also by the nitrogen (N) sink strength in the plant. Stand density may influence leaf dynamics through its effects on light gradient and on plant growth and reproduction. This study tests the hypothesis that the control by the light gradient is manifested more in the vegetative period, whereas the opposite ...
