The Dinocrates-Alexander episode of book 2 supplies the reader with a complex heuristic for differentiating good architects from bad. Vitruvius claims to rely on his knowledge and writing in anticipation of his own success, whereas he attributes Dinocrates’ renown to an attractive bodily appearance. A close intertextual reading of the passage threaded through Livy 1 suggests that Alexander and Dinocrates violate the ideal architect–autocrat relationship. The manner in which one interprets the episode indicates whether one can distinguish altruism from ambitio and the like. Alexander’s appetitious reaction to Dinocrates and his body is further problematized by the latter’s nudity and evocation of Hercules and athletic victors. Discussions in the rhetorical handbooks indicate that arguments concerning a plaintiff’s or defendant’s bodily state can support arguments about his character. The handbooks seem to presume a widespread valorization of what the Greeks would call καλοκἀγαθία‎, but there is an implicit acknowledgment that beauty dissimulates vice. The athletic and/or gladiatorial body is therefore a particular locus of contestation and controversy, as Cicero’s (and Sallust’s) depictions of Catiline show. On the Greek side, writers as early as Tyrtaeus and Xenophanes had suggested that wisdom is better than strength. Isocrates frames the issue politically, and Vitruvius takes it one step further. Following the Roman handbooks that viewed the cultivation of bodily attributes (vs. the fortuitous possession of those attributes) as the primary signifier of character, Vitruvius suggests that athletes are ethically and politically bankrupt, while writers deserve triumphs and apotheosis. Archimedes, Socrates, and even Vitruvius himself provide counterexamples.

Reaction of cerium ammonium nitrate and tetrafluoroterephthalic acid in water afforded two new metal-organic frameworks with UiO-66 [F4_UiO-66(Ce)] and MIL-140 [F4_MIL-140A(Ce)] topologies. The two compounds can be obtained in the same experimental conditions, just by varying the amount of acetic acid used as crystallization modulator in the synthesis. Both F4_UiO-66(Ce) and F4_MIL-140A(Ce) feature pores with size < 8 Å, which classifies them as ultramicroporous. Combination of X-ray photoelectron spectroscopy and magnetic susceptibility measurements revealed that both compounds contain a small amount of Ce(III), which is preferentially accumulated near the surface of the crystallites. The CO<sub>2</sub> sorption properties of F4_UiO-66(Ce) and F4_MIL-140A(Ce) were investigated, finding that they perform better than their Zr-based analogues. F4_MIL-140A(Ce) displays an unusual S-shaped isotherm with steep uptake increase at pressure < 0.2 bar at 298 K. This makes F4_MIL-140A(Ce) exceptionally selective for CO<sub>2</sub> over N<sub>2</sub>: the calculated selectivity, according to the ideal adsorbed solution theory for a 0.15:0.85 mixture at 1 bar and 293 K, is higher than 1900, amongst the highest ever reported for metal-organic frameworks. The calculated isosteric heat of CO<sub>2 </sub>adsorption is in the range of 38-40 kJ mol<sup>-1</sup>, indicating a strong physisorptive character.

In SBR plants for nutrient removal it is often necessary to add supplementary rbCOD during the anoxic phase to obtain complete nitrogen removal. In addition to the aeration, this supply of high-quality BOD is a non-negligible part in the operating costs. Because of the complexity of the bighly interconnected biological processes a heuristic approach for process optimization is hardly possible. Therefore the Nitrification Denitrification Biological Excess Phosphorus Removal (NDBEPR) model of Wentzel et al. and a numerical optimization a1goritbm were used to optimize SBR time scheduling, i.e. minimize both effluent concentrations and operating costs. It was found that a sequence of short aerobic/anoxic phases appears to be better than the usual sequence (one aerobic phase followed by one anoxic phase). This result was validated on a 500 I scale SBR. The optimized process saves up to 50% on extra BOD supply and up to 30% on aeration time. Moreover, it was shown that these cost savings were not at the expense of the phosphorus removal efficiency or the nitrification rate. From an additional numerical optimization it was seen that the ideal SBR time scheduling may depend on the loading. Therefore. a control strategy hased on OUR and ORP measurements is proposed.

The standard procedure to determine (analytically) the values of the quark masses is to relate QCD two-point functions to experimental data in the framework of QCD sum rules. In the case of the light quark sector, the ideal Green function is the pseudoscalar correlator which involves the quark masses as an overall multiplicative factor. For the past thirty years this method has been affected by systematic uncertainties originating in the hadronic resonance sector, thus limiting the accuracy of the results. Recently, a major breakthrough has been made allowing for a considerable reduction of these systematic uncertainties and leading to light quark masses accurate to better than 8%. This procedure will be described in this talk for the up-, down-, strange-quark masses, after a general introduction to the method of QCD sum rules.

We present the calculated equations of state (EOSs) for deuterium–xenon mixtures using mixing rules. Three mixing rules, which are the ideal rule, volume rule, and pressure rule, were used for the calculations, and the thermodynamic self-consistency was evaluated. The volume rule predicts the pressures of mixtures rather accurately, but it fails in the predictions of energies. The pressure ionization has an impact on energy and pressure. Furthermore, the calculated results of the mixing rules were compared with average-atom molecular dynamics (AAMD) simulations, and the pressure rule performs better than the ideal and volume rules over the investigated range.

The study proposed a model called trend data hybrid multilayered perceptron network (TD-HMLP) coupled with a modified recursive prediction error (MRPE) training algorithm as a nonlinear modeling. An on-line model was used to forecast speed, revolution and fuel balanced in a Proton Gen2 car tank. The car measured the injected fuel from fuel injection sensor and become an input for the TD-HMLP model to forecast the speed, revolution and fuel balanced in tank. These forecasted variables were also measured from the car sensors. The criterions for performances are based on the one step ahead forecasting (OSA), multi-step ahead forecasting (MSA) and adjusted R2. The forecasting result showed that TD-HMLP network is better than the conventional HMLP network to maintain higher value in adjusted R2 and produce better step in multi-step ahead forecasting. These preliminary results show that the proposed modeling approach is capable to be used as an on-line information forecaster of a moving car.

This review discusses the techniques and uses of atraumatic restorative treatment (ART) and interim therapeutic restoration (ITR) and states the differences between these two approaches. ART and ITR are similar approaches and are performed using the same material, but they differ in the purpose of their use. ART is used in cases when there are obstacles to reaching dental care units and has been proven to have high success rates in primary and permanent dentitions. ITR is used as a temporary restoration that will be replaced with a more definitive one. ITR is used in cases when the ideal dental treatment cannot be performed. Conventional glass polyalkenoate (ionomer) restorative cement (GIC) is the material of choice that has been used for ART and ITR. This is because of its fluoride release properties, including its ability to bond to enamel and dentine, its pulpal biocompatibility, and its ease of manipulation. High-viscosity glass ionomer performed better than low and medium-viscosity glass ionomer in ART. Combining GIC with conditioner, as well as the use of a chemo-mechanical approach, improved the success rate of ART. Both ATR and ITR are acceptable strategies, with success rates comparable to the traditional treatment methods.

A simple one-step heparin sepharose preparation of better than 95% pure human antithrombin III (AT3) has been developed along with a modification of the iodine monochloride method that allows consistent iodination of it. Iodination at a ratio of ~0.7 I atom/1.0 AT3 molecule results in loss of ca. 5% total thrombin neutralizing activity but negligible reduction in rate of reaction with thrombin. After iodination with 131I unreached 131I-products are removed by washing the 131I-AT3 on a second heparin sepharose column. Before injection the *I-AT3 is sterilized by millipore filtration. By this method autologous *I-AT3 can be prepared and reinjected into the patient in 36-48 titor less if desired. Serial measurements are made of plasma 131I-AT3, plasma TCA-soluble 131I, and whole body 131I, (using a whole body counter). Since human AT3 is ~ the same molecular weight as albumin if allowance is made for its increased catabolic rate its kinetic behavior should be predictable from results of our earlier studies with human autologous albumin. This is not found to be so and human *I-AT3 shows the same delay in catabolismos dog *I-AT3. Current studies indicate that this anomalous behavior is unlikely to invalidate estimates of AT3 catabolism but may result in considerable errors in estimates of total Interstitial AT3. As with our dog studies these suggest a protective role for AT3 in the interstitial fluids

For large-radius bending metal sheets with severe springback, an automatic compensation program based on APDL language was developed to achieve the ideal die geometry. To raise compensation efficiency, the range of the ideal compensation factor based on one-step springback analysis was deduced, and tests prove that more iterations will be needed if compensation factor was beyond the range, and proper selection of compensation factor among the range can be conducive to high compensation efficiency.

Clinical Relevance Resin-dentin bonds, which may have an influence on the long-term success of restorations, are prone to deterioration after cyclic loading. The tested one-step self-etching system (Etch&Prime 3.0) provided the least reliable dentin adhesion. After acid etching of dentin, alcohol/based adhesives performed better than those containing acetone as solvent.

In spite of titanium’s excellent combinations of lightweight, mechanical properties, and corrosion resistance it has been excluded from many applications because of its high cost in fabricated componentry. The major cost to produce a titanium alloy component is the processing of the sponge into alloy plus the several processing steps for fabricating the final finished component. If low cost titanium is to become a reality, the cost of post sponge processing to final finished components must be dramatically reduced. Processing to convert sponge directly in one step to an alloyed near net shape low cost component has been demonstrated. The mechanical properties are equivalent to better than standard processed wrought titanium. Example, automotive components and other applications that confirm titanium componentry at substantially lower cost than standard processing will be provided.
