We discuss two experiments in which requirements engineering techniques has been used and evaluated. In the first experiment a technique called Executable Use Cases is applied in the development of an IT system for public utility services. In the second experiment a technique called Activity Cases is applied in the development of an IT system for a public library. For each experiment we discuss...

Two experiments were conducted to examine the effects of divided attention on activity-based prospective memory. After establishing a goal to fulfill an intention upon completion of an ongoing activity, successful completion of the intention generally suffered when attention was being devoted to an additional task (Experiment 1). Forming an implementation intention at encoding ameliorated the n...

Gesonula punctifrons (Stal,1861) a common acridid of same age group were considered and treated with Arsenic salt. ChE activity was found to be increased between 3 and 6 times in compared to the control with the advancement of doses during the experiment of 96 hours. Such huge increase in the activity was probably due to cholinergic imbalance in the brain. Our present study indicated the conspi...

The design and the implementation of a genetic algorithm are described. The applicability domain is on structure-activity relationships expressed as multiple linear regressions and predictor variables are from families of structure-based molecular descriptors. An experiment to compare different selection and survival strategies was designed and realized. The genetic algorithm was run using the ...

treated with different coating and application of methyl salicylate and salicylic acid are used for reduce chilling injury and maintain the quality of citrus fruit during storage. this experiment was carried out in order to study enzyme activity that involved in reducing chilling injury and maintain the fruit quality based on split plot design with three replications. fruits was treated and the...

this experiment was conducted in order to evaluate the effects of foliar application of ordinary and nano-particles of zinc oxide on the response of corn to salinity. treatments included two corn genotypes (seed mass and sc 704), three spray levels (zinc oxide, nano-sized zinc oxide, and a spray of water treatment) and three salinity levels (0, 75 and 150 mm nacl). shoot dry matter was decrease...

This research work intended to study some important operational parameters on the photocatalytic activity of a new type of poly(methyl methacrylate) (PMMA)/IL-TiO2 nanocomposite, prepared by microemulsion method. For the first step, it is confirmed that the prepared nanocomposite has a significant effect on photodecomposition of the Trypan Blue (TB), as an anionic hydrophilic azo...

In the past few years, the world has taken a new view to herbal remedies and their applications and many researchers in various fields of medicine are studying this subject. In our program searching for antibacterial agents we have selected an extract prepared from the Pentanema divaricata. No report on the antibacterial activity of this species has been published in literature. Pentanema divar...

To test the circadian clock characteristics, activity behaviour of male blackheaded munia was recorded. Two experiments were performed. In experiment 1A, activity of munia was recorded under long days, LD (14L: 10D); and short days, SD (10L: 14D). Locomotor activity of two groups of munia exposed to equinox (12L: 12D) daylength followed by transfer of one group each to continuous dimlight (DD) ...

Unpredictability about upcoming emotional events disrupts our ability to prepare for them and ultimately results in anxiety. Here, we investigated how attention modulates the neural responses to unpredictable emotional events. Brain activity was recorded using functional magnetic resonance imaging (fMRI) while participants performed a variation of the emotional task. Behaviorally, we reported a...
