Compatibility study in natural rubber and maize starch blends
Authors: Khalaf A. I. , Sadek E. M. 
Published: December 2011

AbstractBlends containing various ratios of natural rubber (NR) and maize starch (MS) were prepared on a two roll mill. The effect of starch contents on physico‐mechanical properties and curing characteristics of the prepared blend vulcanizates was investigated. The data indicate poor mechanical properties, delayed cure rate index, and decreased maximum torque with increasing starch content in the blend formulation. This indicates that the interfacial interaction between the blend components was poor. Various contents of the compatibilizers, maleic acid anhydride (MAH) and glycidyl methacrylate (GMA), were mixed with the blend NR/MS (90/10). The effect of the compatibilizer contents on the physico‐mechanical properties and curing characteristics of the binary blend was investigated. Compatibilized blends with GMA (1 phr) showed an improvement in the physico‐mechanical properties in comparison with uncompatibilized blend samples. Blends with MAH exhibited higher modulus and hardness values with respect to GMA blends. The efficiency of the compatibilizers was also evaluated by studies of phase morphology (scanning electron microscope), Fourier transform infrared spectroscopy, and thermal stability (thermogravimetric analysis). © 2011 Wiley Periodicals, Inc.

Random regret minimization or random utility maximization: an exploratory analysis in the context of automobile fuel choice
Authors: Hensher David A. , Greene William H. , Chorus Caspar G. 
Published: December 2011

SUMMARYInterest in alternative behavioural paradigms to random utility maximization (RUM) has existed ever since the dominance of the RUM formulation. One alternative is known as random regret minimization (RRM), which suggests that when choosing between alternatives, decision makers aim to minimize anticipated regret. Although the idea of regret is not new, its incorporation into the same discrete choice framework of RUM is very recent. This paper is the first to apply the RRM‐model framework to model choice amongst durable goods. Specifically, we estimate and compare the RRM and RUM models in a stated choice context of choosing amongst vehicles fuelled with petrol, diesel and hybrid (associated with specific levels of fuel efficiency and engine capacity). The RRM model is found to achieve a marginally better fit (using a non‐nested test of differences) than its equally parsimonious RUM counterpart. As a second contribution, we derive a formulation for regret‐based elasticities and compare utility‐based and regret‐based elasticities in the context of stated vehicle type choices. We find that in the context of our choice data, mean estimates of elasticities are different for many of the attributes and alternatives. Copyright © 2011 John Wiley & Sons, Ltd.
About the possibilities of using the renewable energy power sources on railway transport
Authors: Vorobiev Pavel , Vorobiev Yuri 
Published: December 2011

SUMMARYSeveral electrification systems based on renewable energy power sources (first of all, solar energy) are discussed in respect to their applicability to railway transport and, in particular, to suburban electric trains. Two systems are considered with basic technical details and economic estimation, both including the onboard bank of batteries and the photovoltaic converters (PVC) of solar energy for compensation of energy expenses, which could be positioned either on stations or on wagon's roofs. Sun‐tracking systems and their effect on the solar energy conversion efficiency are discussed in application to stationary and moving PVC platforms. An analysis made shows that introduction of the “green” systems discussed will not only have positive ecological impact, but also can bring a notable economical effect even with today's components, while it could be considerably greater with the usage of new PVCs, which are being developed by the authors.

Environmental Policy, Rankings and Stock Values
Authors: Amato Louis H. , Amato Christie H. 
Published: December 2011

ABSTRACTThis paper examines the impact of Newsweek's ‘The Greenest Big Companies in America’ on stock values for large companies. Newsweek ranks the biggest Companies in America from one to 500. An event window of ten days following the rankings release to the public was examined to analyze the impact of relative rankings on stock values. Dummy variables were constructed denoting firms ranked in the highest and lowest quartiles. Control variables included return to the Dow Jones Industrial Average, the firm's beta coefficient and total revenue. The main finding of the study is that inclusion in the top quartile of the rankings has a positive and statistically significant impact on firms' stock values, while the coefficient for the lowest quartile was not statistically different from zero. The results provide evidence of a positive impact on stock values from favorable environmental recognition but no effect for low ranked firms.

Pyridine‐Based Lanthanide Complexes Combining MRI and NIR Luminescence Activities

AbstractA series of novel triazole derivative pyridine‐based polyamino–polycarboxylate ligands has been synthesized for lanthanide complexation. This versatile platform of chelating agents combines advantageous properties for both magnetic resonance (MR) and optical imaging applications of the corresponding Gd3+ and near‐infrared luminescent lanthanide complexes. The thermodynamic stability constants of the Ln3+ complexes, as assessed by pH potentiometric measurements, are in the range log KLnL=17–19, with a high selectivity for lanthanides over Ca2+, Cu2+, and Zn2+. The complexes are bishydrated, an important advantage to obtain high relaxivities for the Gd3+ chelates. The water exchange of the Gd3+ complexes (kex298=7.7–9.3×106 s−1) is faster than that of clinically used magnetic resonance imaging (MRI) contrast agents and proceeds through a dissociatively activated mechanism, as evidenced by the positive activation volumes (ΔV≠=7.2–8.8 cm3 mol−1). The new triazole ligands allow a considerable shift towards lower excitation energies of the luminescent lanthanide complexes as compared to the parent pyridinic complex, which is a significant advantage in the perspective of biological applications. In addition, they provide increased epsilon values resulting in a larger number of emitted photons and better detection sensitivity. The most conjugated system PheTPy, bearing a phenyl–triazole pendant on the pyridine ring, is particularly promising as it displays the lowest excitation and triplet‐state energies associated with good quantum yields for both Nd3+ and Yb3+ complexes. Cellular and in vivo toxicity studies in mice evidenced the non‐toxicity and the safe use of such bishydrated complexes in animal experiments. Overall, these pyridinic ligands constitute a highly versatile platform for the simultaneous optimization of both MRI and optical properties of the Gd3+ and the luminescent lanthanide complexes, respectively.
