An afocal two-element holographic imaging system is presented. This system can be used to work in white light. The holographic optical elements (holographic lenses) are made as thick phase holograms on silver halide sensitized gelatin (SHSG) and they present a…

Nowadays, the material disassembly is an important issue for the industry. This paper presents an algorithm to sequence the task to be performed in the disassembly of a specific material from a product or to separate all the materials of…

In recent years, holographic optical elements have been introduced in different applications such as high-density data storage, interconnections, spatial and temporal filters and three-dimensional displays. Simultaneously, more sensitive, efficient and durable holographic materials have been developed. Thus it is necessary…

Drawing partly on personal experience, the author of this article seeks to unpack the expertise that service users bring to the design and delivery of mental health services. Service user involvement cannot be imposed by policy diktat from above, she…

In this paper, I first refer to the center-periphery dichotomy in terms of scientific output, placing emphasis upon the relation that exists between science and technology development, on the one hand, and social and economic development, on the other. I…

A wide kinetic study has been carried out under different conditions in TG and TG–MS for each material, at different operating conditions. Runs were carried out at three different atmospheres: N2, N2:O2 4:1 and N2:O2 9:1. In addition to the…
