Excess sludge from wastewater treatment plants (WWTPs), the hotpot of antibiotic resistance genes (ARGs), is widely deposed by composting due to abundant nutrients. However, few studies applied sludge compost products (SCP) as soil amendments because of ARGs and heavy metals in sludge. To...

Project scheduling is one of the core elements of project management, which is essential for engineering-to-order manufacturing companies to improve productivity, reduce costs and shorten project finish time. This paper explores the multi-mode project scheduling problem under resource and finish...

We present an approach to automate the bidding and budgeting of multi-unit digital advertising campaigns. Such campaigns typically involve groups of ad-units that span multiple user segments, ad-delivery channels and media that together are meant to deliver on the advertiser's goals. Our model...

Social cost studies report that alcohol use and misuse impose a great economic burden on society, and over half of the total economic costs are estimated to be due to the loss of work productivity. Controversy remains, however, as to the magnitude and direction of the effects of alcohol...

Design of the cheap and high efficiency catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is imperative for rechargeable Zn-batteries (r-ZABs). Herein, the cobalt nanoparticles encapsulated in iron and nitrogen co-doped urchin-like porous carbons (Co@Fe-Nx/C) as a...

A traveling-wave flow field is proposed and investigated for the performance improvement effect of proton exchange membrane fuel cell (PEMFC). This study analyzes the influence of multiple structural parameters of traveling-wave length, wave height, wave number, and wave spacing on the flow law,...
