In one of his Letters of Old Age from 1367–68, Petrarch observed that while travel added something to his experience and knowledge of things, it had diminished his knowledge of literature by keeping him away from his study. Indeed, neither hardships at sea nor perils would have kept him from traveling even “to the ends of the earth, to China and the Indies, and . . . the most distant land of Ta...

Introduction: The number of foreign travelers arriving in India has shown an exponential increase from 1.2 million in 1981 to 8.03 million in the year 2015, with an annual growth rate of 4.5%. With the influx of internationally mobile students to developing countries such as India comes the responsibility of having to cater to the health needs of these visitors. The current stu...

This paper examines the current features of and future possibilities for electronic books. After a brief history of printing and the introduction of electronic publishing, the forms and features of eBooks will be described. The strengths and weaknesses of eBooks will then be examined along with other related issues. It will be concluded that eBooks hold the promise for obtaining widespread use ...

A book Bp is a union of p triangles sharing one edge. This idea was extended to a generalized book Bb,p, which is the union of p copies of a Kb+1 sharing a common Kb. A graph G is called an H-saturated graph if G does not contain H as a subgraph, but G∪ {xy} contains a copy of H, for any two nonadjacent vertices x and y. The saturation number of H, denoted by sat(H,n), is the minimum number of ...

A set of q triangles sharing a common edge is called a book of size q. We write β (n,m) for the the maximal q such that every graph G (n,m) contains a book of size q. In this note 1) we compute β ( n, cn ) for infinitely many values of c with 1/4 < c < 1/3, 2) we show that if m ≥ (1/4− α)n with 0 < α < 17, and G has no book of size at least ( 1/6 − 2α ) n then G contains an induced bipartite gr...
