Abstract The expansion of agriculture in the southeast Amazon-Savanah transitional area has greatly decreased forest cover and influenced stream structure functioning. We assessed effects loss on integrity streams by assessing physical conditions taxonomic functional diversity fish assemblages this area. hypothesize that low cover, especially adjacent to streams, results poor (e.g., warmer temp...

Waste scavenging is an emerging challenge faced by many Municipalities and Local Authorities in Namibia. However, it has been neglected authorities due to insufficient knowledge about its contribution resource recovery recycling. This study investigated how waste as a problem can be transformed into opportunity for Integrated Management The main objective of the was determine socio-economic dri...

In this paper we investigate the problem of simultaneously allocating orders and mobile storage racks to static pickers. Here are allocated pickers enable them pick all products for that have been them. Problems type considered here arise in facilities operating as robotic fulfilment systems. We present a formulation an integer program discuss complexity problem. two heuristics (matheuristics) ...

The literature on dirty workers analysed material and symbolic aspects of work, highlighting how deal with the stigma associated their occupations. This approach put less attention who operate in informal economy, which is a relevant category especially some sectors, such as urban-waste management recycling. Drawing 2019–2022 qualitative study waste pickers (WPs) Rio Grande do Sul state (Brazil...

The motion of a stone skimming over a water surface is considered. A simplified description of the collisional process of the stone with water is proposed. The maximum number of bounces is estimated by considering both the slowing down of the stone and its angular stability. The conditions for a successful throw are discussed. © 2003 American Association of Physics Teachers. @DOI: 10.1119/1.151...

This paper discusses issues that relate to student mobility and implications for teachers and guidance officers. Whilst there has been a tendency to locate problems associated with mobility in the children themselves or in their families, it is argued that this is not a particularly productive approach. Taking lessons from recent literacy understandings and using data from a study about the chi...

Motivation The importance of managers in maintaining high levels of warehouse performance (quality, productivity, flexibility, safety, sustainability, responsiveness) has been shown before in several studies. However, the impact of shop floor workers, specifically forklift drivers, has not been studied so far. As internal transportation is critical in many warehouses, it can be expected that, i...
