The Morning Dawn, Bar Harbor, Maine: a Very Comprehensive Poem Illustrating and Describing the Scenic Beauty of the United States; Lafayette National Park, the Queen of Resorts
A scan of a third souvenir edition of a 38 page pamphlet that includes a poem by Reverend Leonard W. A. Luckey, Ph. D. The poem is illustrated with several photographs of the Bar Harbor area, including the Otter Creek Cliffs, Sieur De Monts Road and Spring, tent camping in Lafayette (now Acadia) National Park, and Cadillac Mountain, noting that it had been known as Green Mountain.

Graphics and its application to the progress and cost analyses of a house building construction company
In the graphical analyses of Stresses in Framed Structures, we study, by means of diagrams, the stability or equilibrium of structures and the relation between the external forces and the stresses created in the members of the frame. The principle involved is that we may represent any force both as to direction and intensity by a straight line, by considering the direction of the line to be identical with that of the force and adjusting its length according to any arbitrary unit adopted for the forces under consideration. By this means we can solve the stresses in framed structures with a wonderful degree of accuracy. True not absolutely correct but as nearly accurate as the practical design of any member in the structure can be --Pages 13-14
Intrinsic and Rashba Spin-orbit Interactions in Graphene Sheets
Starting from a microscopic tight-binding model and using second order
perturbation theory, we derive explicit expressions for the intrinsic and
Rashba spin-orbit interaction induced gaps in the Dirac-like low-energy band
structure of an isolated graphene sheet. The Rashba interaction parameter is
first order in the atomic carbon spin-orbit coupling strength and first
order in the external electric field perpendicular to the graphene plane,
whereas the intrinsic spin-orbit interaction which survives at E=0 is second
order in . The spin-orbit terms in the low-energy effective Hamiltonian
have the form proposed recently by Kane and Mele. \textit{Ab initio} electronic
structure calculations were performed as a partial check on the validity of the
tight-binding model.Comment: 5 pages, 2 figures; typos corrected, references update
