ABSTRACT The International Gamma-Ray Astrophysics Laboratory (INTEGRAL), launched in 2002, continues its successful work observing the sky at energies E > 20 keV. legacy of mission already includes a large number discovered or previously poorly studied hard X-ray sources. growing INTEGRAL archive allows one to conduct an all-sky survey including deep extragalactic fields and deepest ever...
Abstract Meteotsunamis are shallow-water waves that, despite often being small (~0.3 m), can cause damage, injuries, and fatalities due to relatively strong currents (>1 m s −1 ). Previous case studies, modeling, localized climatologies have indicated that dangerous meteotsunamis occur across northwest Europe. Using 71 tide gauges Europe between 2010 2017, a regional climatology was made und...
Introduction Conclusions References
An asymptomatic 8-week-old male infant was referred for assessment. A prenatal ultrasound had been suggestive of a congenital cystic adenomatoid malformation (CCAM). Following delivery, he had a plain chest radiograph (fig. 1) and went on to have a computed tomography (CT) scan of the thorax (fig. 2), which showed an extrapulmonary mass close to the vertebral column. He proceeded to have magnet...
After 120 yr of burial in moist, well-aerated sand, 23 seeds of Verbascum blattaria and two seeds of a Verbascum sp. germinated and produced normal plants (50% germination for Verbascum). After a 6-wk cold treatment, a single seed of Malva rotundifolia germinated also, producing a normal plant (2% germination). Plants were grown to maturity in a greenhouse, and flowering was induced by exposure...
A 40-yr-old female presented with dyspnoea on minimal exertion and a paroxysmal dry cough, keeping her awake for long periods. The shortness of breath was reported to be progressive over the last 18 months. She had never smoked and was not on medication. There was no recent history of travelling and she only had a dog at home. Her medical history was marked with autosomal dominant polycystic ki...
exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. measurement of the annual radiation dose hazards was performed using a halogen-quenched gm tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. the gm tube was plac...
background: human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. materials and methods: an in situ assessment of the indoor and outdoor background radiation in akwanga and keffi towns of nasarawa state nigeria was carried out using a halogen-quenched geiger muller (gm) detector (insp...
