A global, comprehensive review of terms and definitions related to paper recycling was conducted in this article. Terms and definitions related to paper recycling have varied in the course of time. Different terms and different definitions for the same thing are being used in different geographical regions and by different organizations. Definitions are different based on varying conceptions of...

In normal human skin fibroblasts (HSFs), fluorescent glycosphingolipid analogues are endocytosed and sorted into two pools, one that is recycled to the plasma membrane and one that is transported to the Golgi complex. Here, we investigated glycosphingolipid recycling in Niemann-Pick type A and C lipid storage disease fibroblasts (NPFs). Cells were incubated with a fluorescent analogue of lactos...

T cell activation requires sustained signaling at the immune synapse, a specialized interface with the antigen-presenting cell (APC) that assembles following T cell antigen receptor (TCR) engagement by major histocompatibility complex (MHC)-bound peptide. Central to sustained signaling is the continuous recruitment of TCRs to the immune synapse. These TCRs are partly mobilized from an endosomal...

Kish Island is a popular tourist destination in Iran, and tourism plays an important role in its economy. The volume of waste produced in the island has increased given the construction of numerous industrial projects over the past decade, as well as an increase in the tourist population. This expansion signals a need to create new methods of waste disposal. Environmental Impact Assessment (EIA...

The usage of valuable resources and the generation of emissions during the life cycle of photovoltaic (PV) technologies dictate our proactive planning for a sound PV recycling infrastructure to ensure its sustainability. Some global PV manufacturers have begun recycling PV wastes generated from the PV manufacturing processes and the Endof-Life (EoL) PV modules. Therefore, it is vital to develop...

A balance between endocytosis and membrane recycling regulates the composition and dynamics of the plasma membrane. Internalization and recycling of cholesterol- and sphingolipid-enriched lipid rafts is an actin-dependent process that is mediated by a specialized Arf6-dependent recycling pathway. Here, we identify myosin1c (Myo1c) as the first motor protein that drives the formation of recyclin...

We analyze the economic incentive structure as well as the environmental implications of the current national policy for recycling notebook computers (NB’s) in the nation of Taiwan. Using cost–benefit analysis and formal life cycle assessment (LCA) we critique the current program and recommend future improvements. The current policy requires manufacturers to pay a recycling fee for each unit so...

We described previously a mechanistic model of whole-body protein turnover in rodents. Channeling was defined as the flow of amino acids from the extracellular compartment to aminoacyl tRNA and protein synthesis. Recycling was defined as the flow of amino acids from protein degradation to aminoacyl tRNA (protein synthesis) without mixing with the intracellular pool of amino acids. In this paper...

Designers of heavy ion (HI) and Z-pinch inertial fusion power plants have explored the potential of recycling the target and recyclable transmission line (RTL) materials as an alternate option to disposal in a geological repository. Although the physics basis of the HI and Z-pinch concepts is widely different, many of the recycling issues facing both designs are quite similar. This work represe...

Problem: The demand of beverages in PET bottles is constantly increasing. In this context, environmental, technological and regulatory aspects set a stronger focus on recycling. Generally, the reuse of recycled material from post-consumer PET bottles in bottle-to-bottle applications is seen as least environmentally harmful. However, closedloop systems are not widely implemented in Europe. Previ...
