A former colleague of mine used to argue that there was really no such thing as cost optimisation. He was, of course, quite correct. We can only optimise within the constraints of our current knowledge and experiences. In attempting to discover where the future direction of cost studies in buildings lies, this book fo…
The analysis set out in the preceding pages has concentrated on the years 1941-9, with some attention being paid to the important pre-1941 era. The emphasis throughout has been on Soviet-American relations, as they dominated the world scene from 1943 onwards. Great Britain was important before that date but its econom…

Cells are the basic elements of all systems in living nature. The process of cellular differentiation underlies most natural systems’ capacity for functional integration and adaptation. In the Emergent Technologies and Design programme multifaceted cell research has been conducted over a number of years, ranging from…
Kristalline Halbleiter-Nanobänder wurden durch „Ausrollen“ von Kern-Schale-Nanodrähten erhalten. Zum Beispiel wurden Ge-Nanodrähte mit einer Si-Schale umhüllt, an der Oberseite durch Ionenätzen aufgeschlitzt und an den Seiten mit einer dünnen Schicht Photoharz geschützt. Der Ge-Kern wurde dann auf chemische Weise sele…

Hydrogen generation by the reaction of pure Al powder in water with the addition of Al(OH)3, γ- Al2O3, α-Al2O3, or TiO2 at mild temperatures was investigated. It was found that the reaction of Al with water is promoted and the reaction induction time decreases greatly by the above hydroxide and oxides. X-ray diffracti…
We felt strongly that the actual construction of the structure was much simpler that it appeared in the drawing set. Therefore, in a precursor to Building Information Modeling (BIM), we built a large-scale model and photographed each step of the construction in the order we envisioned it would be built in actuality (fi…
Motivated by the recent experiments on EuS/Bi$_2$Se$_3$ heterostructures, we study the temperature dependent screening effects on the surface of a three-dimensional topological insulator proximate to a ferromagnetically ordered system. We find that the long-range Coulomb interaction is screened at finite temperatures…
STRUCTURAL GLASS: SCL GLASS HEADQUARTERS AND SHOWROOM The glass pavilion (figure 22.1) designed as a headquarters and showroom for SCL, a glassmanufacturing company in Brisbane, Australia, was our first project starting the practice in 2002. The pavilion was meant to showcase the glass production, fabrication, and insta…
Os acos de baixa liga sao acos-carbono acrescidos de elementos de liga os quais melhoram algumas propriedades. Exemplos de elementos de liga: cobre, manganes, molibdenio, niquel, fosforo, vanadio, zirconio. A adicao desses elementos de liga produz aumento de resistencia do aco a corrosao atmosferica. Esse trabalho vem…
The crystal structure of layered metal IrTe2 is determined using single-crystal x-ray diffraction. At T=220 K, it exhibits Ir and Te dimers forming a valence-bond crystal. Electronic structure calculations reveal an intriguing quasi-two-dimensional electronic state, with planes of reduced density of states cutting dia…
Diatoms (Bacillariophyta) are one of the most diverse algal groups in the Antarctic Region and play a dominant role in almost all freshwater and terrestrial ecosystems. Despite this overall occurrence, little is known about the diversity, ecology and biogeography of this group in the Maritime Antarctic Region. The mai…
A method of producing graphene by the electrochemical insertion of alkylammonium cations in a solvent into graphite is disclosed.
Se ha demostrado que el óxido de niobio mesoporoso es un catalizador eficaz para la deshidratación de D-xilosa a furfural, alcanzando una conversión del 92% y un rendimiento de furfural 49,3% a 170º C y 90 minutos. La lixiviación de Nb, determinada por ICP-MS, era inferior al 0,5% en peso de la concentración de Nb ini…
Jeklarska industrija danes predstavlja glavno gonilo svetovnega gospodarstva. Proizvodnja jekla se iz leta v leto povecuje. Jekleni izdelki in polizdelki se uporabljajo v razlicnih panogah gospodarstva kot so gradbenistvo, avtomobilska industrija, zdravstvo in se drugje. Kupci želijo jeklo najvisje kakovosti, zato je…
