WEEE recycling: Research, development, and policies
- 2016
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- WEEE Recycling: Research, Development, and Policies covers policies, research, development, and challenges in recycling of waste electrical and electronic equipment (WEEE). The book introduces WEEE management and then covers the environmental, economic, and societal applications of e-waste recycling, focusing on the technical challenges to designing efficient and sustainable recycling processes-including physical separation, pyrometallurgical, and hydrometallurgical processes. The development of processes for recovering strategic and critical metals from urban mining is a priority for many countries, especially those having few available ores mining. Describes the two metallurgical processes-hydro- and pyro-metallurgy-and their application in recycling of metals Provides a life cycle analysis in the WEEE recycling of metals Outlines how to determine economic parameters in the recycling of waste metals Discusses the socio economic and environmental implication of metal recycling.

Information Systems Development: A Systematic Approach
- 1981
-
Bok (refereegranskat)abstract
- Information Systems are built for people - to help them to do a better job ... to help them improve their activities.The ISAC approach is a systematic aid to the development of such systems. Here you will find the culmination of nearly 10 years work in the Research Group ISAC (Information Systems work and Analysis of Changes) at the Department of Administrative Inforamtion Processing, Royal Institute of Technology and the University of Stockholm in Sweden.In the Scandinavian countries, the ISAC apporach is in widespread use both in academic education and business application. Recent international interest in this approach has encouraged authors Lundeberg, Goldkuhl and Nilsson to translate into English this most comprehensive of all books on the subject - for students in computer science ... systems analysts ... designers ... programmers ... and EDP managers.Pacing special emphasis on analysis and design, the book "Information Systems Development" will prepare you to develop information systems according to the ISAC approach. You will find that the authors' use of continuing real-life case studies of information systems development projects add to interest - and contribute to this singularly readable overview of systematic approach to information systems development

Biomedical applications of lanthanum
- 2010
-
Bok (populärvet., debatt m.m.)abstract
- Book Description: Lanthanum has been used as a tracer to study tight junctions in epithelia by transmission electron microscopy. The key function of the tight junction complex (TJC) is to limit the paracellular permeability by forming a selectively permeable barrier between the apical and basolateral compartment of the extracellular space. Impaired regulation of the TJC causes a variety of diseases, such as autoimmune diseases, cancer development, infections, allergies and asthma. The advantage of lanthanum as an opaque probe is its small ionic radius (0.11 nm), compared to alternative methods, such as radioactive isotope techniques using extracellular tracers and light microscopy techniques with larger polar molecules. This book presents a variety of biomedical applications of lanthanum.
