The WEB Book experiments in electronic textbook design
This paper describes a series of three evaluations of electronic textbooks on the Web, which focused on assessing how appearance and design can affect users' sense of engagement and directness with the material. The EBONI Project's methodology for evaluating electronic textbooks is outlined and each experiment is described, together with an analysis of results. Finally, some recommendations for successful design are suggested, based on an analysis of all experimental data. These recommendations underline the main findings of the evaluations: that users want some features of paper books to be preserved in the electronic medium, while also preferring electronic text to be written in a scannable style
From the visual book to the WEB book : the importance of design
This paper presents the results of two studies into electronic book production. The Visual book study explored the importance of the visual component of the book metaphor for the production of more effective electronic books, while the WEB book study took the findings of the Visual book and applied them to the production of books for publication on the World Wide Web (WWW). Both studies started from an assessment of which kinds of paper book are more suitable for translation into electronic form. Both also identified publications which are meant to be used for reference rather than those which are read sequentially, and usually in their entirety. This group includes scientific publications and textbooks which were both used as the target group for the Visual book and the WEB book experiments. In this paper we discuss the results of the two studies and how they could influence the design and production of more effective electronic books

The Potential of Freeform Construction Processes
The level of automation technology and processes control found in modern day construction
lags significantly behind other industries such as automotive and aerospace. The construction
industry has health and safety issues and still uses traditional methods of procurement. These
problems are compounded by diminishing skills in the labour force. Methods of production
must change if these issues are to be resolved and Freeform Construction is a collection of
processes that could have potential impact. This paper outlines some of the major issues
facing construction and sets a context with examples of digital fabrication in construction.
Freeform Construction is defined and potential applications are presented and related to
application scale. The viability of two potential applications are investigated in terms of cost.Mechanical Engineerin

Summary of Lee v. Ball, 121 Nev. Adv. Op. 38
This case involved an appeal from a district court judgment in a personal injury case, entered pursuant to a jury verdict which initially awarded the plaintiff 8,200 and prejudgment interest, without offering the defendant a new trial on damages
\u3ci\u3eThe Arab conquests in Central Asia\u3c/i\u3e
The Arab expedition in Central Asia in 642. Herat and Badghis submitted without a blow, and the first serious check to their advance was met in the Murghab valley. A second expedition occupied Juzjan, Faryab, Talaqan, and Balkh, territories of Afghanistan
Studies on Aromatic Structure
Diazoacetic ester has been reacted with anthracene, benzanthracene and pyrene. In each case an acid has been obtained by hydrolytic treatment of the reaction mixture. The acid from anthracene has been assigned the structure naphthonorcaradienecarboxylic acid XXV on the basis of hydrogenation experiments and ultra-violet light absorption data. Oxidative degradation has proved the acid from benzanthracene to be benznaphthonorcaradiene-carboxylic acid XXXIV, while the product from pyrene is apparently tribenznorcaradienecarboxylic acid XXXVII. Attention is drawn to the remarkable stability shown by these condensed cyclopropane acids towards attempted rearrangement. An explanation for this is proposed on the grounds of the ability of the cyclopropane ring to conjugate with aromatic centres
Uniaxial magnetocrystalline anisotropy in
is a paramagnetic metal and since its low temperature
resistivity is described by with , it
is also considered a non-Fermi liquid (NFL) metal. We have performed extensive
magnetoresistance and Hall effect measurements of untwinned epitaxial films of
. These measurements reveal that exhibits
uniaxial magnetocrystalline anisotropy. In addition, the low-temperature NFL
behavior is most effectively suppressed when a magnetic field is applied along
the easy axis, suggesting that critical spin fluctuations, possibly due to
proximity of a quantum critical phase transition, are related to the NFL
behavior.Comment: 7 figure
