Similarities And Differences

With growing interest in the recovery of materials and subassemblies from consumer products at the end of their useful life, there is a need to develop decision-making methodologies that determine how to maximize the environmental benefits of end-of-life processing while minimizing recovery costs. Disassembling products is the most common mechanical procedure of current end-of-life treatment methods. Consequently, quantitative design evaluation from the disassembly perspective has received special attention in the research literature. Unfortunately the design of disassembly lines cannot be achieved by simply reversing the order of the mechanical assembly of the products involved. The aim of this paper is to demonstrate the similarities and differences of the assembly and disassembly processes through a practical real-world example.

Development Approach

When NC State University recently hired me to lead a course concentration in sustainable design, I began to hone in on what sustainable product development and design translate to and its actionable applications. Sustainable product development and design of current and future consumer products and services are methods that create a proactive versus a reactive approach. The development of sustainable products and systems must start at the beginning phase of ideation and continue through the entire process to achieve multiple design purposes and duration with a designated end-of-life plan. In contrast, generally, products are developed with end of life and longevity as a secondary thought, and with recycling as a potential option. If the goal is the longevity of a product or service, one needs to look beyond recycling and more at the concept of development. A sustainable product development approach and design thinking are how to accomplish product longevity.

Transmission Electron

Ultraviolet radiation (UVR) from all three waveband regions of the UV spectrum, UVA (320-400 nm), UVB (290-320 nm), and UVC (200-290 nm), can be emitted by some medical devices and consumer products. Sunlamps can expose the blood to a considerable amount of UVR, particularly UVA and/or UVB. The percent transmission of each waveband through the epidermis to the dermis, which contains blood, increases in the order of increasing wavelength: UVC (10%) < UVB (20%) < UVA (30%). To investigate the effects of UVR on white blood cells, we chose transmission electron microscopy to examine the ultrastructure changes in L5178Y-R murine lymphoma cells.

Synthesis of a thin, buried dielectric layer to form a silicon-on-insulator (SOI) material by high dose oxygen implantation (SIMOX – Separation by IMplanted Oxygen) is becoming an important technology due to the advent of high current (200 mA) oxygen implanters. Recently, reductions in defect densities from 109 cm−2 down to 107 cm−2 or less have been reported. They were achieved with a final high temperature annealing step (1300°C – 1400°C) in conjunction with: a) high temperature implantation or; b) channeling implantation or; c) multiple cycle implantation. However, the processes and conditions for reduction and elimination of precipitates and defects during high temperature annealing are not well understood. In this work we have studied the effect of annealing temperature on defect and precipitate reduction for SIMOX samples which were processed first with high temperature, high current implantation followed by high temperature annealing.

Purpose Palliative care is a philosophy of care that encompasses holistic, patient-centric care involving patients and their family members and loved ones. Palliative care patients often have complex needs. A common challenge in managing patients near their end of life is the complexity of navigating clinical decisions and finding achievable and realistic goals of care that are in line with the values and wishes of patients. This often results in differing opinions and conflicts within the multidisciplinary team. Conclusion This article describes a tool derived from the biopsychosocial model and the 4-quadrant ethical model. The authors describe the use of this tool in managing a patient who wishes to have fried chicken despite aspiration risk and how this tool was used to encourage discussions and reduce conflict and distress within the multidisciplinary team.

Four Levels

This article addresses the unique roles of social work and speech-language pathologists (SLPs) in end-of-life and hospice care settings. The four levels of hospice care are explained. Suggested social work and SLP interventions for end-of-life nutrition and approaches to patient communication are offered. Case studies are used to illustrate the specialized roles that social work and SLP have in end-of-life care settings.
