Phosphatidylinositol 3-phosphate [PtdIns(3)P] regulates endocytic trafficking and the sorting of receptors through early endosomes, including the rapid recycling of transferrin (Tfn). However, the phosphoinositide phosphatase that selectively opposes this function is unknown. The myotubularins are a family of eight catalytically active and six inactive enzymes that hydrolyse PtdIns(3)P to form ...

There has been increased focus on recycling in Sweden during recent years. This focus can be attributed to external environmental factors such as tougher legislation, but also to the potential gains for raw materials suppliers. Recycling centres are important components in the Swedish total recycling system. Recycling centres are manned facilities for waste collection where visitors can bring, ...

A closed-loop recycling process is being investigated (using membrane technology) to remove soils from industrial surface cleaning Operations. This recycling process combines cleaning chemical (aqueous and semi-aqueous formulations), cleaning equipment and closedloop recyding methods tb minimize soil loading in a parts cleaning process. Closed-loop recycling and the need for it is the primary t...

Whether coat proteins play a widespread role in endocytic recycling remains unclear. We find that ACAP1, a GTPase-activating protein (GAP) for ADP-ribosylation factor (ARF) 6, is part of a novel clathrin coat complex that is regulated by ARF6 for endocytic recycling in two key physiological settings, stimulation-dependent recycling of integrin that is critical for cell migration and insulin-sti...

What Won’t Get Harvested, Where and When: The Effects Of Increased Paper Recycling On Timber Harvest Peter J. Ince, Ph.D. USDA Forest Service Pulp and paper production and paper recycling have increased in recent decades to unprecedented levels throughout the world. This paper presents a review and comparison of regional trends in timber harvest, pulp and paper production, waste paper recovery ...

The potential environmental impact of Landfilling, Incineration and Recycling of spent household alkaline batteries collected in continental Portugal was compared using LCA methodology and the Recipe Impact Assessment method. Major contributors and improvement opportunities for each system were identified and scenarios for 2012 and 2016 legislation targets were evaluated. For 13 out of the 18 i...

Despite the societal importance of reusing waste materials, few empirical studies have specifically examined recycling behaviors as differentiated from attitudes and intentions. This paper reviews the empirical studies of recycling, summarizes research findings, and identifies areas for future research. The effects on recycling behavior of both personal variables (personality, demographics, and...

This paper examines our understanding of recycling behaviour in the context of its increasing normalisation in the UK. It reflects on the recent history of dry recycling (i.e. recycling of ‘dry’ materials such as paper, glass, plastics and cans) and asks the question as to what influence policy drivers and the increased provision of facilities for recycling have had on people’s behaviour. In re...

The paper analyses the determinants of household recycling in Italy with particular emphasis on social behaviour. The econometric analysis is based on two waves 1998 and 2000 of the Multipurpose Household Survey conducted annually by the Italian Central Statistics Office. In Italy household recycling was substantially voluntary in the years from 1998 to 2000 with no monetary incentives or pecun...

Cell migration and adhesion are critical for immune system function and involve many proteins, which must be continuously transported and recycled in the cell. Recycling of adhesion molecules requires the participation of several proteins, including actin, tubulin, and GTPases, and of membrane components such as sphingolipids and cholesterol. However, roles of actin motor proteins in adhesion m...
