The regular and predictable nature of the tide makes the generation of electricity with a tidal lagoon or barrage an attractive form of renewable energy, yet storm surges affect the total water-level. Here, we present the first assessment of the potential impact of storm surges on tidal-range power. Water-level data (2000e2012) at nine UK tide gauges, where tidal-range energy is suitable for de...

Thirteen repetitions of a cross-channel transect in the Khuran Channel within the Strait of Hormuz allowed the description of the mean flow and semidiurnal tidal properties of a northsouth transect. Water velocity profiles were obtained with a 614.4 kHz TRDI Work Horse Broadband ADCP along this 3.3 km long transect on 10 October 2014, the third day of secondary spring tide. The M2, M4 and M6 fr...

Background: Use of hormone replacement therapy (HRT) may increase the risk of adult-onset asthma in women. Various in vitro studies have reported that estradiol stimulates human mast cell lines causing release of allergic mediators which was not observed in estrogen receptor-alpha (ER-alpha) knockout mice. Thus, estrogen might be a key element in occurrence of asthma. In the present study, we p...

Indoor radon activities were measured during a period of 6 months, as well as several physical environmental variables (temperature, pressure, humidity and rainfall). The location was a small room at an administrative building of the University of Coimbra, usually undisturbed by human activities and situated over bedrock of low-uranium Triassic red sandstones. A low average activity of radon wa...

A highly accurate two-color interferometer with automatic correction of the refractive index of air was developed for crustal strain observation. The two-color interferometer, which can measure a geometrical distance of approximately 70 m, with a relative resolution of 2 × 10 −9 , clearly detected a change in strain due to earth tides in spite of optical measurement in air. Moreover, a large st...

1. Recordings were made of the pattern of breathing during and after smoking a cigarette in 14 smokers and nine non-smokers. 2. The most consistent effect was an increase in tidal volume during smoking which reverted to baseline over 1-2 min. Changes in breath times were smaller and less consistent. Similar effects were observed with intermittent inhalations of charcoal. 3 In four subjects the ...

tidal triggering mechanism, ibecause a similar process appears to trigger terrestrial volcanic eruptions (4), and perhaps earthquakes as well (5). The terrestrial situation is somewhat obscured, however, because of the complicating loading effects of oceanic and atmospheric tides, ocean currents, and atmospheric circulation. The moon has provided another clear, albeit luxurious, view of the ear...
