Public opinion polls consistently show a high percentage of the U.S. population, typically more than 75 percent, consider themselves to be environmentalists. One of the issues that environmentalists feel most strongly about is recycling. In many communities there is an almost religious fervor surrounding recycling. Unfortunately, there also appears to be widespread misunderstanding regarding th...

This study aims to identify processes, current situations, and issues of recycling systems for four home appliances, namely, air conditioners, television receivers, refrigerators, and washing machines, among e-wastes in China and Japan for understanding and comparison of their characteristics. In accordance with results of a literature search, review of information disclosed online, and questio...

Recycling endosomes feed autophagy B y identifying a protein that hampers membrane traffi cking within the cell, Longatti et al. provide evidence that recycling endosomes supply membrane to growing autophagosomes. When cells are stressed or hungry, they often eat some of their contents through the process of autophagy, in which a membrane compartment called an autophagosome forms and scoops up ...

A preponderance of textbooks outlines cellular protein synthesis (translation) in three basic steps: initiation, elongation, and termination. However, researchers in the field of translation accept that a vital fourth step exists; this fourth step is called ribosome recycling. Ribosome recycling occurs after the nascent polypeptide has been released during the termination step. Despite the rele...

solid waste management system is a collection of activities used for regulate society waste in the manner of engineering and sanitary. in order to have waste management system in rural areas there should be appropriate building capacity. the status quo of functional elements in rural solid waste management system in iran includes collecting and disposing in the ground. the mean of per capita pr...

Cell membranes are out of thermodynamic equilibrium notably because of membrane recycling, i.e., active exchange of material with the cytosol. We propose an analytically tractable model of biomembrane predicting the effects of recycling on the size of protein nanodomains also called protein clusters. The model includes a short-range attraction between proteins and a weaker long-range repulsion ...

Accumulating evidence suggests that integrin recycling regulates cell migration. However, the lack of reagents to selectively target the trafficking of individual heterodimers, as opposed to endocytic transport as a whole, has made it difficult to define the contribution made by particular recycling pathways to directional cell movement. We show that autophosphorylation of protein kinase D1 (PK...

Small to medium-sized enterprises (SMEs) in Hobart, Tasmania, Australia face many barriers to recycling participation. This study first investigated the volumes and types of waste produced by SMEs. Significant barriers were then identified and key motivators to recycle examined. Using the Australia New Zealand Standard of Industrial Classification, stratified sampling of SMEs (n = 436) was unde...

Aminoglycosides are widely used antibiotics that cause messenger RNA decoding errors, block mRNA and transfer RNA translocation, and inhibit ribosome recycling. Ribosome recycling follows the termination of protein synthesis and is aided by ribosome recycling factor (RRF) in bacteria. The molecular mechanism by which aminoglycosides inhibit ribosome recycling is unknown. Here we show in X-ray c...

The small GTPase Rab5 regulates the early endocytic pathway of transferrin (Tfn), and Rab5 deactivation is required for Tfn recycling. Rab5 deactivation is achieved by RabGAP5, a GTPase-activating protein, on the endosomes. Here we report that recruitment of RabGAP5 is insufficient to deactivate Rab5 and that developmentally regulated GTP-binding protein 2 (DRG2) is required for Rab5 deactivati...
