Using electron beam lithography fine Au<SUB>60</SUB>Pd<SUB>40</SUB> wire samples have been made, which were then used to investigate size effects in disordered systems. The wires made had widths from 140nm to 36nm, and lengths from 125nm to 100μm. The thickness was varied from 10nm to 50nm. Using gas etching techniques it was possible to make these wires free-standing with lengths of over 100μm and thicknesses of 10nm. At first some of the important electrical and mechanical properties of the free-standing wires were investigated. The tensile strength was found to be much larger than that found in bulk gold, and a simple model was developed to predict at what voltage the wires would melt. At low temperatures localisation and interaction contributions to the resistance were seen both in wires on a substrate and when free-standing. Electric field heating of the wires on a substrate was used to find the electron-phonon scattering time, which was seen to be proportional to T<SUP>-2</SUP>. The resistance rise for the free-standing wires was less than for the same wires on a substrate. Magnetoresistance measurements revealed this to be due to an increased negative localisation term in the presence of strong spin orbit scattering. The inelastic lengths were consistent with strong magnetic scattering which was reduced on being made free-standing. Electric field heating of the free-standing wires revealed that the thermal conduction of the wire is dominated by the electron contribution. At 1K the phonons in the wires should be one dimensional, but no contribution to the heat conduction was observed from these phonons. Below 800mK conductance fluctuations were observed in the magnetoresistance of the short samples. Below 125 K the amplitude of the fluctuations saturated which is consistent with both the interaction and the inelastic lengths being longer than the wire.

ABSTRACT This paper treats the standing waves formed by two progressive waves possessing same properties but opposite direction in stationary atmosphere and uniform depth. The third-order approximation to two-wave trains interactions obtained by Chen¡]1990¡^is cited. From the solution that can be reduced to the cases such as standing waves, the properties resulted in standing wave due to the nonlinear interactions between two wave trains intersection, particularly, the two peaks of wave pressure, are described clearly. Furthermore, the profile, pressure and angular frequency is also verified in good agreement with the experimental results.

The concept of moral standing applies to those who are of a direct moral concern, i.e. we have a reason to directly include those with a moral standing in our moral deliberation- they matter for themselves. How one accounts for the concept in question is controversial and thus there are several different accounts that one can consult when pondering what content the concept ought to have. This paper investigates the plausibility of some of the most influential accounts of moral standing, concluding that they, as they stand alone, are insufficient. Instead an alternative account of moral standing with a kantian foundation is offered, an account which is heavily based on Christine Korsgaard’s notion of final goods, with moral standing understood as a comparative concept as its distinguishing component.
