Although atmospheric tides driven by solar heating are readily detectable at the earth’s surface as variations in air pressure, their simulations in current coupled global climate models have not been fully examined. This work examines near-surface-pressure tides in climate models that contributed to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC); it compar...

Abstract. Storm tides represent a major threat to the low-lying German North Sea coast. Knowledge of extremes is essential for design reliable and robust coastal defences. A storm tide that occurred on 12–13 March 1906 along Bight coastline still represents one strongest events record. For this event, detailed knowledge atmospheric hydrodynamic conditions lacking. To assess potential impact suc...

Over thirty occurrence of Ocean storm surges events over the Nigerian coastline were recorded between 1994-2012 and each with its devastating consequences resulting from the massive coastal flooding and erosion. It revealed that all Ocean storm surges apart from the surges of march 2002 were experienced in summer months of April to October, but more frequent in August. Some evidences in the Wes...

The role of the lower brain stem in controlling preovulatory gonadotropin surges was investigated in female rats under acute experimental conditions. Electrolytic lesions or diethyldithiocarbamate implantations in the ventrolateral part of the medulla oblongata (VLMO), which were carried out at 1100-1330 h on the day of proestrus, resulted in a blockade of the preovulatory surges of LH, FSH and...

Ovulation and pseudopregnancy (psp) can be induced by cervical stimulation in persistent estrous rats maintained in a constant lighting condition (LL-psp rats). Different from the pattern of prolactin (PRL) secretion in usual psp rats maintained in a daily light-dark cycle (LD-psp rats), PRL secretion in these rats during the psp period does not occur in the form of two daily surges. The object...

Vibrios were isolated from red tides caused by Mesodinium rubrum and also throughout the year in the Ria de Pontevedra, Spain. The isolates were grouped into 14 phena by numerical toxonomy. Strains associated with red tides were restricted to four phena: phena I and II were Vibrio alginolyticus, and phena III and IV were Vibrio tubiashii and Vibrio anguillarum, respectively. V. anguillarum-like...

4-Hydroxyanisole (4-OHA) was administered to C57Bl/lOJ mice in which B16 melanoma or Lewis lung carcinoma had been implanted s.c. or i.m. The drug had the largest antitumour effect against B16 melanoma growing s.c. and a smaller antitumour effect against B16 melanoma or Lewis lung carcinoma growing i.m. In the treatment regimens where drug was administered only after tumour implantation, a sign...

Abstract. Floods in the Venice city centre result from superposition of several factors: astronomical tides; seiches; and atmospherically forced fluctuations, which include storm surges, meteotsunamis, surges caused by atmospheric planetary waves. All these factors can contribute to positive water height anomalies individually increase probability extreme events when they act constructively. Th...
