In TSPD Pty Ltd v Resortrez Pty Ltd [2008] QSC 001 Fryberg J made an order permitting the applicant to inspect and copy documents which had been produced to the court under a subpoena, but had remained in the registry. Though not essential to the decision the judgment contains some interesting discussion about the construction of r 242 of the Uniform Civil Procedure Rules 1999 (Qld) (UCPR).

Lead tin telluride is one of the well-established thermoelectric materials in the temperature range 350-750 K. In the present study, Pb0.75-xMnxSn0.25Te1.00 alloys with variable manganese (Mn) content were prepared by solid state synthesis and the thermoelectric properties were studied. X-ray diffraction, (XRD) showed that the samples followed Vegard's law, indicating solid solution formation and substitution of Mn at the Pb site. Scanning Electron Microscopy (SEM) showed that the grain sizes varied from <1 mu m to more than 10 mu m and MnTe rich phase was present for higher Mn content. Seebeck coefficient, electrical resistivity and thermal conductivity were measured from room temperature to 720 K. At 300 K, large Seebeck values were obtained, possibly due to increased effective mass on Mn substitution and low carrier concentration of the samples. At higher temperatures, transition from n-type to p-type indicated the presence of thermally generated carriers. Temperature dependent electrical resistivity showed the transition from degenerate to non-degenerate behavior. For thermal conductivity, low values (similar to 1 W/m-K at 300 K) were obtained. At higher temperatures bipolar conduction was observed, in agreement with the Seebeck and resistivity data. Due to low power factor, the maximum thermoelectric figure of merit (zT) was limited to 0.23 at 329 K for the sample with lowest Mn content (x=0.03). (C) 2015 Elsevier Ltd. All rights reserved.

Westerly wind bursts (WWBs) that occur in the western tropical Pacific are believed to play an important role in the development of El Niño events. Here, following the study of Lengaigne et al. (Clim Dyn 23(6):601–620, 2004), we conduct numerical simulations in which we reexamine the response of the climate system to an observed wind burst added to a coupled general circulation model. Two sets of twin ensemble experiments are conducted (each set has control and perturbed experiments). In the first set, the initial ocean heat content of the system is higher than the model climatology (recharged), while in the second set it is nearly normal (neutral). For the recharged state, in the absence of WWBs, a moderate El Niño with a maximum warming in the central Pacific (CP) develops in about a year. In contrast, for the neutral state, there develops a weak La Niña. However, when the WWB is imposed, the situation dramatically changes: the recharged state slides into an El Niño with a maximum warming in the eastern Pacific, while the neutral set produces a weak CP El Niño instead of previous La Niña conditions. The different response of the system to the exact same perturbations is controlled by the initial state of the ocean and the subsequent ocean–atmosphere interactions involving the interplay between the eastward shift of the warm pool and the warming of the eastern equatorial Pacific. Consequently, the observed diversity of El Niño, including the occurrence of extreme events, may depend on stochastic atmospheric processes, modulating El Niño properties within a broad continuum.

The purpose of this chapter is to examine the effects of legal involvement of crime victims on their psychological adjustment. First, causes of possible effects are described, which may be located within the procedure or the outcome of the legal process. Then, the available evidence is reviewed, most of it suggesting that legal involvement does not strongly affect the victims' psychological adjustment, neither negatively nor positively. The chapter continues with a discussion of whether victims should be advised to report the assault to the police or not, and it describes relevant decision criteria, such as victim adjustment retributive justice, victim compensation, victim security and societal security. Finally, suggestions for future research are outlined, pointing to necessary methodological improvements in the design of future studies on legal involvement.

In French contemporary poetry, some poets have wished to return to —and so to increase the value of— the enunciation of the poetic subject. In such poetic scenario, the poet James Sacré exemplifies a new approach that tries to re-establish contact with the expression of the poetic subject, albeit always avoiding the pitfalls of excessive ornamentation and poetic effusiveness. Based on the use of simple language, this approach attaches value to legibility and does not hesitate to tap into the most banal or dullest aspects of reality. This article studies one of the procedures used by the poet to reestablish the expression of the poetic subject. This procedure seeks to rewrite life gestures—a technique that evinces an unavoidable relationship between life and poetic words in the work of James Sacré.
