  • This module will introduce you to several advanced topics concerning the operation and convergence of the Recycle unit operation. The HYSYS Recycle logical operation is used to solve looped systems where downstream material is mixed back in upstream in the process. The Recycle is a logical operation; it does not transform the stream that passes through it. The Recycle operation can be used several times in a given simulation. Every time a recycle operation is added, the total time needed for the simulation to successfully calculate and converge increases.

  • Recycling of plastic materials is now an important field in the plastics industry, not just an activity born under environmental pressure. The recycling processes include industrial operations in which secondary materials are reprocessed and/or monomers recovered for further polymerization; such processes are termed secondary and tertiary recycling.

  • Though a quarter of a century has elapsed since the first edition of Business Cycles, the opportunities it opened up for further research remain largely unexploited. The chief exception is Schumpeter's own Capitalism, Socialism, and Democracy. Much has been published on innovation and entrepreneurship, usually with a nod in Schumpeter's direction but no more. Even a work like Yusif A.

  • Personal protective equipment (PPE) includes clothing or other special equip- ment that is issued to individual workers to provide protection against actual or potential exposure to ionizing radiations. It is used to protect each worker against the prevailing risk of external or internal exposure in circumstances in which it is not reasonably practicable to provide complete protection by means of engineering controls or administrative methods. Adequate personal protection depends on PPE being correctly selected, fitted and maintained.

  • The initiative that emerged from these discussions within ARL came to be known as the “Cloud Library” project, because it posited a future in which library collections and services would be sourced from external providers, reducing local infrastructure and operational expenditures in a manner analogous to the cloud-sourced business and computing solutions that now prevail in the commercial and high-tech sectors. Funded by The Andrew W.

  • This symbol on the product or on its packaging indicates that this product shall not be treated as household waste. Instead it shall be handed over to the applicable collection point for the recycling of electrical and electronic equipment. By ensuring this product is disposed of correctly, you will help prevent potential negative consequences for the environment and human health, which could otherwise be caused by inappropriate waste handling of this product. The recycling of materials will help to conserve natural resources.

  • ‘Eco-procurement’ is already a key concept for operators, manufacturers and policy- makers, not least because railway rolling stock is often used for 30 years or more. Adherence to strict environmental performance specifi cations, including energy effi ciency, noise, diesel-exhaust emissions and recycling, must be considered when rail suppliers submit tenders.

  • Redo Log History All transactions are recorded in the online redo log files. This allows for automatic recovery of transactions in the event of a database failure. If the database is configured for NOARCHIVELOG mode, no redo history is saved to archived log files, and recovery operations are limited and a loss of transaction work may occur. This is the result of the automatic recycling of log files, where older log files needed for recovery are overwritten and only the most recent part of the transaction history is available.

  • 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.

  • 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....

  • There’s no real conservation inside their buildings, no removal of materials of concern, no forethought on product recyclability. If you are really going to be green, you consider the entire lifecycle of your operation. It has to be part of your culture to find every opportunity to reduce or eliminate your impact. In our business, we are seeing these barriers falling fast. Two years ago, companies felt they had time to study options and decide to act…or not. Now, the “do nothing” or “business-as-usual” approach has become unacceptable to their stakeholders.
