The plant is equipped with two batteries, 12 V 100 Ah, Depth Discharge (DoD) 80% each, which enables the system to store 1920 Wh as reserve. According farmer’s report, one essential components was...

The efficiency of overhead power lines can be increased by series compensation or HVDC transmission. These complex systems can be protected from overvoltages by metal oxide surge arresters. Both porcelain and polymer tube design surge arresters are used for these applications, however, polymer tube design surge arresters offer various advantages over porcelain arresters such as light weight, ex...

The destructive surge transient response is an expected phenomenon on a turbo charged automobile. Therefore a new intelligent controller to prevent the surge phenomenon to prolong the life cycle of modern turbo charged automobiles is proposed in this paper. In order to do so, the surge boundary for a particular turbo charger in a specific automobile must be determined first. A new systematic wa...

The ability of the arterial baroreflex to regulate blood pressure may influence the magnitude of the morning surge in blood pressure (MSBP). The aim was to investigate the relationships between sympathetic and cardiac baroreflex sensitivity (BRS) and the morning surge. Twenty-four hour ambulatory blood pressure was recorded in 14 young individuals. The morning surge was defined via the pre-awak...

Two experiments were performed to examine the temporal requirements of the estradiol signal for the GnRH and LH surges in the ewe. Hypophyseal portal and jugular blood (to measure GnRH and LH, respectively) were sampled from ewes set up in an artificial follicular phase model. After progesterone withdrawal to simulate luteolysis, circulating estradiol was raised to a preovulatory level by inser...
