In this paper, I investigate the moral status of agricultural biotechnology and, more specifically, genetically modified (GM) crops by employing the hubris argument. The old notion of hubris, given to us by the ancient Greeks, provides a narrative from which we can understand ourselves and technology. Ronald Sandler offers us an understanding of hubris he claims gives us a prima facie reason and a presumption against the use of GM crops. I argue that Sandler’s hubris argument fails for several reasons: (1) Sander and many others fail to have a proper understanding of agriculture as an inherently technological practice which is radically different from ‘nature’; (2) the notions of control and manipulation which are central to the concept of hubris are difficult to understand and use in the context of agriculture; (3) trying to establish a prima facie reason against GM crops runs into serious difficulty since many GM crops are profoundly different from each other; and (4) even if we accept Sandler’s argument of hubris, it actually plays no role in the reasoning and evaluation of the moral status of different GM crops. © 2014, Springer Science+Business Media Dordrecht.

We have fabricated by pulse laser deposition very thin (∼5-7 nm) and thick (∼27-408 nm) films of composition Fe66B24Nb4Ni6 on silicon and quartz substrates respectively, and studied their magnetic and magneto-optic properties at room temperature. We find that the thicker films on silicon can be tuned by appropriate thermal annealing to exploit soft magnetic characteristics with low HC, and high MS values. The magnetic hysteretic loops of the as-deposited thicker films on silicon substrates show two interesting characteristics: 1) increase in the coercivity with the film thickness and 2) the onset of a two stage process during the approach to magnetic saturation. The initial in-plane characteristic of the hysteresis loop is followed by a linear anisotropic behavior between remanence and saturation- that changes into square soft-magnetic loops on decreasing the film thickness. By suitable annealing the intrinsic strain disappears at relatively low temperatures (≤200°C); the thicker films can be tailored to exhibit a simple soft-magnetic square loop with low HC. The ∼5-7 nm films deposited on glass are transparent and have been investigated for their magneto-optic properties using Faraday rotation (FR) measurement technique. Very high values of FR in the range 4-20 deg/μm almost linearly dependent on the wavelength of light in the range 405-611 nm are observed. The observed high values of Faraday rotation over a wide range of wavelength of light are useful for the applications as magneto-optic sensors in the UV to visible range.

The Design for Repeatedly Utilization (DFRU) is a proposed concept to be used in the product realization process to ensure optimum useable life (for instance in terms of economy, resource usage, environmental impact etc.) of products or parts of products enabling multiple lifecycle. In the DFRU approach products are restored as new like products through remanufacturing processes. The term remanufacturing has been interpreted differently by different researchers and the industries that are involved in remanufacturing business use different approaches to remanufacture their products. In this paper the starter motor and alternator of automotives has been used to demonstrate the novel concepts. The purpose of this paper is to express what remanufacturing means in our concept, model their major lifecycle aspects and create a simulation model from it. This is a preliminary work towards defining and specifying the processes, methods and design properties in DFRU. The work will be further extended to a holistic business model which can facilitate DFRU approach in an efficient way. In future the model will be developed and adopted to create new models for other products appropriate for remanufacturing and eventually DFRU.
