This article provides a review of Pear Deck which allows teachers to create interactive slide presentations. In this article, we first provide an overview Decks’ features and some background information about tool. Then, discuss its technological as well pedagogical features. Next, evaluate the teacher fit in terms theoretical underpinning tool how it can support student learning. We underline ...

There is a concern with worldwide deterioration of highway bridges, particularly reinforced concrete. Due to the corrosive nature of steel re-bars used in concrete bridge decks, the service-life of these bridges is reduced. The advantages of advanced composite materials (ACM) over conventional materials motivate their use in highway bridges for rehabilitation and replacement of structures. Howe...

A classic experiment used in testing for ESP abilities has the following general form. A deck of cards, consisting of a, identical cards of type i, 1 I i I r, is shuffled and placed face down (in most such experiments r = 5 and a, = 5 for 1 I i _( 5). The subject then attempts to correctly guess the type of each card as the cards are sequentially removed from the deck. In previous work [2,3], s...

BACKGROUND In their working activity, seafarers are exposed to high levels of stress that should be accuratelyinvestigated, measured, followed up and, if possible, countered. This is also required by regulations recently entered into force such as the Maritime Labour Convention 2006, recommending to consider special physiological or psychological problems created by the shipboard environment. T...

To understand the (British) Royal Navy at the time of the Napoleonic Wars, it is necessary to appreciate the extent to which they were not a new episode for the navy but rather the latest iteration of a repeated challenge that had existed since 1689. Moreover, the navy had institutional and career continuity, and indeed to a much greater extent than its Continental rivals. As a result, it is ne...

This survey discusses recent developments in the context of spherical designs and minimal energy point configurations on spheres. The recent solution of the long standing problem of the existence of spherical t-designs on S with O(td) number of points by A. Bondarenko, D. Radchenko, and M. Viazovska attracted new interest to this subject. Secondly, D. P. Hardin and E. B. Saff proved that point ...

High performance concrete (HPC) bridge decks are prone to premature cracking if movement is restrained. Internal curing (IC) can reduce shrinkage cracking in concrete structures, thus improving their performance and service life. However, there is very limited information available in the literature on the possible extension of service life due to internal curing. This paper addresses this ques...

Abstract The application of lightweight sandwich material as a ship structure was an innovative breakthrough that provided excellent strength-to-weight ratio. In the process, proposed structural design and scantling must be designed according to equivalent strength requirement with low weight compared existing structure. research aims evaluate dynamic response different construction systems bar...

On July 10, 1940, amidst fear of Nazi invasion, a prison ship, sorts, left Liverpool, England, crammed full over two thousand male ‘Enemy Aliens’ – Germans, Austrians, and some Italians. They were herded together, below deck, with all hatches sealed. Some prisoners war, passionate Nazis, but most Jewish refugees. Among them was Walter Benjamin's estranged son, young man 22 years, Stefan Rafael ...
