Within the project RECLAF (Resource Classification Framework for Old Landfills in Flanders) the resource recovery potential of approximately 2,000 historic landfills in Flanders is prospected. The research project’s goal is to systematically provide information for the future management of these former landfill sites, e.g. whether the sites are to be mined or not and under which conditions. The...

This paper describes the analysis of raw wood flows in Slovakia. Material flow analysis was used to reveal and quantify relations between the resources and the primary uses of wood. In particular, two approaches to wood flow modelling were utilised wood balance and wood resource balance. Wood balance was introduced to illustrate a global view of the resources and primary uses of roundwood in Sl...

a 3-km reach of the luján river was studied by establishing 6 sampling stations, which were from 300 to 500 m apart. the first station was the control reading for river nutrients and particulate material. the second station measured the continuous effluent from a wastewater treatment plant flow of the city of luján and was, therefore, considered a continuous addition point of nutrients. the oth...

Five dogs, 10 weeks old, underwent operation using ketamin-HCl anesthesia and end-to-end anastomoses of the femoral and brachial arteries were made using polyfilament nonabsorbable material (Ethibond), monofilament nonabsorbable material (Prolene), polyfilament absorbable material (Vicryl) and monofilament absorbable material (PDS). The arterial diameter using a micrometer and blood flow using ...

Material flow analysis (MFA) describes a class of methods that allow analysing and designing material and energy flow systems like supply chains, eco-industrial parks or production sites. Material flow networks are one of the methods in the field of MFA. Based on the Petri nets, the material flow network make it possible to conduct static MFA (steady-state modelling) as well as dynamic MFA (con...

This study experimentally examines the flow of glass spheres in a wedgeshaped hopper that is vibrated horizontally. When the hopper is discharged without vibration, discharge occurs as a hnnel flow, with the material exiting the central region of the hopper and stagnant material along the sides. With vibration, the discharge of the material occurs in reverse, with the material along the sides e...

Globalized procurement markets, increasing product customization and variety, and shorter innovation cycles increase the complexity and dynamics in logistics systems. This is particularly true at the node in distribution networks, in which goods are combined, compiled order-specifically and redistributed. A growing number of products, small batch sizes and highly variable orders, which are ther...
