We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...

Estimation of the dynamic characteristics of buildings is a key issue in seismic design technology. Since 1957, the Building Research Institute (BRI), Japan, has been operating a network to monitor strong motion in buildings. In this study, dynamic characteristics of 25 actual buildings in the BRI network were estimated by using strong motion records. Acceleration records from two sensors respe...

The name, Silk Road (German: Seidenstraße), was first coined in 1877 by the German geographer Ferdinand von Richthofen as a term given to the network of trade routes linking China to Central and West Asia, India and the Mediterranean region. More recently, Peter Frankopan, the director of the Oxford Centre for Byzantine Research, extensively writes about the ancient Silk Road departing from Eur...

BACKGROUND There is increasing evidence that reflux of bile plays a part in the pathogenesis of Barrett's oesophagus. Bile injury to the gastric mucosa results in a "chemical" gastritis in which oedema and intestinal metaplasia are prominent. AIM To determine if patients with Barrett's oesophagus have more bile related changes in antral mucosa than patients with uncomplicated gastro-oesophage...

BACKGROUND The cardiovascular risk of obesity is potentially increased by arterial stiffness. OBJECTIVE To assess the relationship of adiposity measures with arterial stiffness in Caucasian adults with intermediate cardiovascular risk. SETTING Six Spanish health centres. PARTICIPANTS We enrolled 2354 adults (age range, 35-74 years; mean age, 61.4±7.7 years, 61.9% male). METHODS This is ...

To assess potential indices of nutritional condition, we examined changes in lipid content and the blood refractive index (BRI) of postlarval, juvenile and adult prawns (Penaeus spp.) that had been starved or fed to different levels of satiation. The whole-body lipid content (WBL) of small juvenile P. esculentus (20–120 mg wet weight) decreased significantly after 12 h of starvation. The WBL of...

star identification is one of the most important stages in attitude determination with star trackers. this can be performed using matching algorithms between observed stars and a master star catalogue. the main challenge in this approach is to provide a fast and reliable identification algorithm that is sufficiently robust in different pointing views of the star tracker optical system in the sp...
