Vehicular emission (VE) is one of the important anthropogenic sources for airborne carbonyls in urban area. Six types of VE-dominated samples were collected at representative locations in Hong Kong where polluted by a particular fueled type of vehicles, including (i) a gas refilling taxis station (liquefied petroleum gas [LPG] emission); (ii) a light-duty passenger car park (gasoline emission);...

pituitary suppression by depot gnrh agonist may be excessive for ovarian stimulation. this study compares the efficacy of a single half-dose depot triptorelin and reduced-dose daily buserelin in a long protocol icsi/et. methods: a total of 182 patients were randomized into two groups using sealed envelopes. pituitary desensitization was obtained in group 1 (91 patients) with half-dose (1.87 mg)...

In this study, a two phase hybrid heuristic approach was proposed to solve the multi-depot multi-vehicle inventory routing problem (MDMVIRP). Inventory routing problem (IRP) is one of the major issues in the supply chain networks that arise in the context of vendor managed systems (VMI) The MDMVIRP combines inventory management and routing decision. We are given on input a fleet of homogeneous ...

Driven by the new laws and regulations concerning emission of greenhouse gases, it is becoming more popular for enterprises to adopt cleaner energy. This research proposes a novel two-echelon vehicle routing problem consisting mixed vehicles considering battery swapping stations, which includes one depot, multiple satellites with unilateral time windows, customers given demands. The fossil fuel...

introduction: safety culture is a set of beliefs, norms, incentives, social and technical roles and functions that make the core of the safety management system. the aim of this study was to examine factors affecting safety culture and its relationship to accident in the oil depots. methods: case-control study was conducted in 2016. 300 employees of 3 oil depot in tehran were selected that 150 ...

This paper deals with the key issue of management to improve the allocation capability, facilitating the optimization of the objective in minimizing the cost, with the accuracy in dynamic allocation of nearest customers to depot. A method has been proposed to solve the Multi Depot Vehicle Routing Problem (MDVRP) based on Ant Algorithm which is a modified version of the traditional Ant colony Op...

Obesity and metabolic syndromes are examples whereby excess energy consumption and energy flux disruptions are causative agents of increased fatness. Because other, as yet elucidated, cellular factors may be involved and because potential treatments of these metabolic problems involve systemic agents that are not adipose depot-specific in their actions, should we be thinking of adipose depot-sp...

E XPLORATION missions on Earth have used the principle of caching for centuries. Caching involves prepositioning discrete quantities of supplies at specific locations along a route in order to lighten the burden or extend the range of an exploring party. Historical missions that made use of caching on Earth are the Lewis and Clark expedition in 1803–1806 [1] and the ill-fated Imperial Trans-Ant...

Container movement involves several stakeholders where each group is focused on achieving its own objectives. By actively considering the perspective of different maritime stakeholders, this paper identifies a set of implementation strategies and prioritizes them to successfully implement an ‘Inland-Depots-for-Empty-Containers’ (IDEC) system in a region. It builds on the authors’ earlier work t...

This paper studies the multi-depot joint distribution vehicle routing problem considering energy consumption with time-dependent networks (MDJDVRP-TDN). Aiming at where travel time depends on variation characteristics of road network speed in area, influence and relationship between load fuel consumption, a optimization model is established to minimize sum fixed cost, cost window penalty cost. ...
