Hand-held technologies have offered less support for learning about space and measurement than they have for other strands of mathematics. This paper describes a recent development which seems promising in this respect, Casio’s ClassPad 300. The mechanisms of providing interactive opportunities for students are described and illustrated, and some possible ways in which this sort of device might...

The solar eclipse has a great influence on the variability of ionosphere because obscuration radiation. Using equatorial electrojet (EEJ) and plasma measurements from Swarm, zonal winds Michelson Interferometer for Global High-resolution Thermospheric Imaging Ionospheric Connection Explorer mission, electron density Constellation Observing Systems Meteorology, Ionosphere, Climate temporal respo...

OBJECTIVE To monitor the effect of a novel nicotine delivery device that may produce fewer carcinogens (Eclipse) on cigarette smoking, carbon monoxide and nicotine concentrations, and motivation to give up smoking. The smoker's own brand of cigarette and a nicotine replacement product (Nicotrol inhaler) were used as comparisons. DESIGN After baseline data were recorded, smokers were randomise...

A solar eclipse is an unusual natural occurrence. Muslims used the phenomenon of a as season for prayer, which was only carried out during from early in until end. Although there no statistically significant difference estimating eclipse, seasons change, becomes increasingly important. Lots alternatives can be reference determination eclipse. Among commonly calculation spherical astronomy. Desp...

BACKGROUND The purpose of this study was to compare the ability of 3 portable oxygen concentrators (POCs) to maintain S(pO2) ≥ 90% during exercise in patients with chronic lung disease. METHODS Twenty-one subjects with chronic lung disease (18 with COPD, 3 with pulmonary fibrosis) and documented room air exertional S(pO2) ≤ 85% performed four 6-min walk tests: a control walk using the subject...

The glyphs, which are presented in full in Figure S13, not only made predictions of a lunar or solar eclipse in a particular month but also what time of day that eclipse might occur. Eclipse times in the glyphs are given as integers on a 12-hour scale using the ancient Greek number system with the alphabet standing for numbers and an additional symbol ς for 6. The times in the glyphs are modifi...

It avoids software failure, reduce development and maintenance cost, improve customer agreement and software quality. ...

A solar eclipse provides a well-characterized reduction in solar radiation, of calculable amount and duration. This captivating natural astronomical phenomenon is ideally suited to science outreach activities, but the predictability of the change in solar radiation also provides unusual conditions for assessing the atmospheric response to a known stimulus. Modern automatic observing networks us...

The purpose is to devise a patient-specific quality assurance procedure for RapidArc radiotherapy using the MapCHECK detector array. We use our existing MapCHECK system and a Solid Water phantom with an embedded ion chamber to develop a quality assurance procedure for RapidArc treatment after commissioning. The ion chamber used to measure the absolute dose is surrounded by 6 cm layers of solid ...

Objective—To monitor the eVect of a novel nicotine delivery device that may produce fewer carcinogens (Eclipse) on cigarette smoking, carbon monoxide and nicotine concentrations, and motivation to give up smoking. The smoker’s own brand of cigarette and a nicotine replacement product (Nicotrol inhaler) were used as comparisons. Design—After baseline data were recorded, smokers were randomised t...
