A tutorial paper with a review of the technologies available in the mid-eighties for surge protection of lowvoltage end-user equipment. The principles of operation are described for “crowbar devices” (now generally described under the standardized name of “voltage switching devices”) and for “voltage clamping devices: (now generally described under the standardized name of “voltage limiting dev...

Pore fluid in a debris flow is not fully understood, despite its contribution to the fluidity of flow. To observe sediment concentrations pore fluids flows, we established novel monitoring system volcanic catchment, southern Japan. An observation culvert, 1.0 m width, 1.5 height and 2.0 length, was placed along stream bank. intake covered by grating equipped on side culvert so that only flows l...

In the aftermath of a natural catastrophe there is an increased demand for skilled reconstruction labor, which leads to significant increases of reconstruction labor wages and hence insured losses. Such inflation effects are referred to as "Demand Surge" effects. It is important for insurance companies to properly account for these effects when calculating insurance premiums and determining the...

The preovulatory GnRH/LH surge in the ewe is stimulated by a rise in the circulating estradiol concentration that occurs in conjunction with preovulatory ovarian follicle development. In the presence of high levels of progesterone, such as during the luteal phase of the estrous/menstrual cycle, the stimulatory effects of elevated estradiol on GnRH/LH secretion are blocked. Recent work in the ew...

We investigated the relationship between the day-night blood pressure (BP) dip and the early morning BP surge in an cohort of 3012 initially untreated subjects with essential hypertension. The day-night reduction in systolic BP showed a direct association with the sleep trough (r = 0.564; P < 0.0001) and the preawakening (r = 0.554; P < 0.0001) systolic BP surge. Over a mean follow-up period of...

Surge protective device is a part of internal lightning protection and it crucially to divert the certain amount of surges to the ground before the protected load able to handle. Therefore, this paper studying the enhancement of SPD through the effect of adding a filter in hybrid surge protection circuit using simulation modeling. Ordinarily, filter is used as in eliminating noises in certain a...

Typhoon Haiyan, which struck the Philippines in November 2013, was an extremely intense tropical cyclone that had a catastrophic impact. The minimum central pressure of Typhoon Haiyan was 895 hPa, making it the strongest typhoon to make landfall on a major island in the western North Pacific Ocean. The characteristics of Typhoon Haiyan and its related storm surge are estimated by numerical expe...

oocyte maturation and embryo development are controlled by intra-ovarian factors such as steroid hormones. progesterone (p4) exists in the follicular fluid that contributes to normal mammalian ovarian function and has several critical functions during embryo development and implantation, including endometrial receptivity, embryonic survival during gestation and transformation of the endometrial...
