in the present study, under typical management conditions of dairy farms in iran, the effect of oral administration of on serum glucose, ast and arginase(indices of liver injuries) of oral monensin was assessed. thirteen multiparous holstein cows were blocked into a control and an experiment group from 3 weeks prepartum to 45 days postpartum according the number of their calvings. the groups re...

Previous studies suggest that there may be a distinct relationship between spontaneous neural activity and subsequent or concurrent self-specific stimulus-induced activity. This study aims to test the impact of spontaneous activity as recorded in an eyes-open (EO) resting state as opposed to eyes-closed (EC) on self-specific versus non-self-specific auditory stimulus-induced activity in fMRI. I...

Chilling damage under 15ºC in anthurium cut flowers reduces the vase-life, quality and marketability of the product. In the present experiment, GABA postharvest treatment (0, 1 and 5 mM) was studied on the vase-life, total soluble solid (TSS), H2O2 content, proline content, spathe browning, catalase and superoxide dismutase enzymes activity of Anthurium andraeanum...

An experimental unit is an opportunity to randomly apply or withhold a treatment. There is interference between units if the application of the treatment to one unit may also affect other units. In cognitive neuroscience, a common form of experiment presents a sequence of stimuli or requests for cognitive activity at random to each experimental subject and measures biological aspects of brain a...

The Application of Reusable Software Components Project (ARSC) formulated an experiment design, data collection plan, and procedures in preparation for a reuse experiment. The reuse experiment is currently in progress and the experiment planning and the results to date are presented. While the design, plan, and procedures were developed to support the investigation of software reuse, they, as w...

This paper describes a preliminary study that investigates new information visualization and data fusion concepts to help provide situation and activity awareness to mission commanders overseeing teams of unmanned vehicle operations engaged in intelligence, surveillance, and reconnaissance (ISR) missions. These display concepts are based on the design concept of activity awareness – a design ap...

Three experiments used rats to investigate the role of dopamine activity in learning to inhibit conditioned fear responses (freezing) in extinction. In Experiment 1, rats systemically injected with the D2 dopamine antagonist, haloperidol, froze more across multiple extinction sessions and on a drug-free retention test than control rats. In Experiment 2, rats extinguished under an intracerebrove...
