This thesis is a research in the technology for paper production from waste paper (non – wood fibers ) , then feasibility study a economical justification for setting up a factory for producing duplex board , with technical and financial study has been performed inaccordance to UNIDO Standard . In packing industries with a capacity 7500 tons per year and the raw material for this process is waste paper. In this thesis paper pulp that needs for board production can be implemented by solving waste paper in the water. This method therefore pollution free and does not have any negative effects on the environment even a considerable amount of water which is extracted from the pulp, istreatment... 

All the biological diagnostic devices that are introduced to the consumers, must meet WHO criteria. Some of these criteria include being affordable, sensitive and deliverable to the user. In the last twenty years, there have been lots of efforts to use microfluidic devices for biological assay. Due to their expensive price and requirement of complex equipment for their fabrication, polymer-based microfluidic devices have not been able to be used in developing countries. It is to be hoped that introduction of paper for fabrication of microfluidic devices could make microfluidic devices meet WHO criteria. μPADs are divided into well-based and channel-based devices. In the present work, both...
