  • Since the first DIISM conference, which took place 9 years ago, the world has seen drastic changes, including the transformation of manufacturing and engineering software, and the information and communication technologies deployed. The conditions for manufacturing and engineering have changed on a large scale, in terms of technology-enabled collaboration among the fields of design, engineering, production, usage, maintenance and recycling/disposal. These changes can be observed in rapidly-growing fields such as supply chain management....

  • Design Guides for Plastics covers each topic in a single page to provide a basic reference to each topic. This space constraint means that each topic is only covered to a basic level. Detailed plastic product design will  always require detailed knowledge of the application, the processing method and the selected plastic.

  • Coal formation has been described as “an inefficiency in the carbon cycle,” (Barghoorn, 1952) when carbon from plants remains in terrestrial sediments and is not recycled to the atmosphere (Figure 1.1.1). Coal is, by definition, a readily combustible rock containing more than 50% by weight and 70% by volume of carbonaceous material (Schopf, 1966). Another definition describes coal as a combustible solid, usually stratified, which originated from the accumulation, burial, and compaction of partially decomposed vegetation in previous geologic ages (Hendricks, 1945)....

  • Gangliosides are sialic acid-containing glycosphingolipids present on mam-malian plasma membranes, where they participate in cell-surface events such as modulation of growth factor receptors and cell-to-cell and cell-to-matrix interactions. Antibodies to gangliosides have been associated with a wide range of clinically identifiable acute and chronic neuropathy syn-dromes.

  • This study, the first to investigate workplace contamination in areas in Ghana where e-waste recycling and disposal is carried out, focussed on the main centre for this type of work, at the Agbogbloshie scrap market in Ghana’s capital, Accra. One of the numerous similar, though far smaller, operations that take place throughout Ghana was also investigated, at the location of a scrap dealer in Korforidua, a smaller city to the north of Accra. At these workshops, e-waste is recycled in a crude way, primarily involving manual disassembly and open burning to isolate copper from plastics.

  • The insect low-density lipoprotein (LDL) receptor (LDLR) homolog, lipo-phorin receptor (LpR), mediates endocytic uptake of the single insect lipo-protein, high-density lipophorin (HDLp), which is structurally related to LDL. However, in contrast to the fate of LDL, which is endocytosed by LDLR, we previously demonstrated that after endocytosis, HDLp is sorted to the endocytic recycling compartment and recycled for resecretion in a transferrin-like manner.

  • This article is devoted to the study of redundancy and yield of salvage pathways in human erythrocytes. These cells are not able to synthesize ATPde novo. However, the salvage (recycling) of certain nucleosides or bases to give nucleotide triphosphates is operative. As the salvage pathways use enzymes consuming ATP as well as enzymes producing ATP, it is not easy to see whether a net synthesis of ATP is possible. As for pathways using adenosine, a straightforward assumption is that these pathways start with adenosine kinase....

  • Wastes are very process-specific but the key pollutants can be derived from knowledge of: the process, construction materials, corrosion / erosion mechanisms and maintenance materials. Waste audits are used to gather information on the source, composition, quantity and variability of all wastes. Waste prevention typically involves preventing the arising of waste at source, minimising the arisings and recycling any waste that is generated.

  • There are so many different techniques of various artists out there. I am not going into every detail as most on this site have at least a basic knowledge of drawing. Materials that I use Sketch book - I chose a pad of recycled paper and of thicker quality so that I can use a darker lead and eraser. It’s important to draw on thicker paper if you want to create a drawing with good detail. Thinner paper is less expensive however drawing with detail requires multiple levels of shading and erasing. Shading excessively on thin paper might put a...

  • Sustainability in natural systems is built on the closed-end process of recycling materials. Our present society produces so much that is not recyclable, like resin-molded chairs and air polluting automobile tires, that it is necessary to apply intention to source reduction and product responsibility. Chapter 18 provides knowledge of municipal solid waste and how to disposal and recovery.

  • Earth's ecosystems continue to exist because they are sustainable. Two fundamental characteristics are crucial to sustainability. First, ecosystems' energy source, the Sun, is non-depletable and non-polluting. Second, there is efficient recycling of nutrients and other chemicals through organisms and through geological and chemical processes that result in no waste accumulation in ecosystems. This chapter provide knowledge of ecosystems: How they work.
