Recycling reduces the total number of trees that are cut down to make paper and can reduce overall demand for wood. But more importantly, paper recycling saves forests. By substituting used paper for trees, recycling reduces the overall intensity of forest management needed to meet a given demand for paper, and the pressure to convert natural forests and ecologically sensitive areas like wetlan...

Increased recycling and elevated cell surface expression of receptors serve as a mechanism for persistent receptor-mediated signaling. We show that the neuron-enriched Na(+)/H(+) exchanger NHE5 is abundantly expressed in C6 glioma cells and plays an important part in regulating cell surface expression of the receptor tyrosine kinases MET and EGF receptor. NHE5 is associated with transferrin rec...

Critical materials share the same insufficiencies in their life cycles; low recycling rates and a high degree of dissipative losses. The limitations for the secondary use of critical materials are their minor concentrations in final products, their dissipative applications, and the fact that they are irreversibly mixed with other material flows in current recycling practices. This is exacerbate...

The preservation of the natural environment requires a reduction in material intensity of economic systems. Recycling is a major method for meeting this requirement. One of the most appropriate formulations for economic recycling models is the introduction of recycling sectors and joint production of waste materials. The models are generally checked for the feasibility of net-production. Such m...

Improper waste disposal and management globally is linked to a variety of problems with the environment and health. This problem can be addressed by following the 3 R’s; reduce, reuse, and recycle. Japan is continually aiming towards becoming a sustainable, recycling oriented society with the implementation of the 3 R’s, reducing GHG emissions, and innovating new technologies for recycling and ...

This paper analyzes a reward system that uses a club good to promote recycling. In particular, we examine a context of incomplete information in which the administrator is unable to observe the resident’s attitude towards recycling. The results suggest that despite the lack of information, the administrator is able to induce all types of residents to recycle when the reward is sufficiently high...

Text recycling, also referred to as self-plagiarism, is the reproduction of an author's own text from a previous publication in a new publication. Opinions on the acceptability of this practice vary, with some viewing it as acceptable and efficient, and others as misleading and unacceptable. In light of the lack of consensus, journal editors often have difficulty deciding how to act upon the di...

This study reviews the problems in the use and disposal of poly (ethylene terephthalate) (PET) and includes the concise background of virgin and recycled PET as well as their possible applications. The current state of knowledge with respect to PET recycling method is presented. Recycling of PET is the most desirable method for waste management, providing an opportunity for reductions in oil us...

A study of 361 female melanoma patients and age matched controls was conducted in the four western provinces of Canada. Analysis of reproductive factors showed a significant negative association between number of livebirths and risk of melanoma. The relationship persisted for superficial spreading melanomas after adjustment for host pigmentation factors, freckling, and educational status. An in...

There is increasing evidence that species extinctions jeopardize the functioning of ecosystems. Overfishing and other human influences are reducing the diversity and abundance of fish worldwide, but the ecosystem-level consequences of these changes have not been assessed quantitatively. Recycling of nutrients is one important ecosystem process that is directly influenced by fish. Fish species v...
