We propose a dynamic model for optimizing the ows of atcars that considers explicitly the broad range of complex constraints that govern the assignment of trailers and containers to a atcar. The problem is formulated as a logistics queueing network which can handle a wide range of equipment types and complex operating rules. The complexity of the problem prevents a practical implementation of a...

Our ultimate objective is to design cost-effective control strategies for Aedes albopictus, the Asian tiger mosquito, an important urban nuisance and disease vector that expanded worldwide during the last 40 years. We conducted mosquito larval surveys from May through October 2009 in the City of Trenton, New Jersey, USA, while performing intensive monthly source-reduction campaigns that involve...

This extended abstract presents a technology for artefactcentric development. Our demonstrator shows how the technology could be used to detect safety hazards that arise from improper storage of chemical containers. We augment real chemical containers with Particle Smart-its that allow them detecting hazards by exchanging knowledge about containers in their proximity. As it is prohibitive in th...

 We introduce a dynamic and stochastic transportation problem consisting of two subproblems. For parcel transportation in hub-and-spoke networks, swap containers are used to carry out hub-to-hub shipments. This constitutes a pickup and delivery problem on the operational level. On the tactical level, empty swap containers are balanced over the hub-network in order to match the stochastic deman...

Mesocyclops longisetus (Thiébaud), Mesocyclops thermocyclopoides Harada, Mesocyclops venezolanus Dussart, and Macrocyclops albidus (Jurine) were tested for their effectiveness in controlling Aedes aegypti (L.) larvae in a variety of containers around homes in El Progreso, Honduras. All four cyclopoid species killed > 20 larvae per cyclopoid per d under container conditions. M. longisetus was mo...

A survey of container-breeding mosquitoes was conducted on urban islands (Big Coppitt Key, Rockland Key, Key West, and Stock Island) and rural islands (Big Pine Key, Cudjoe Key, Little Torch Key, No Name Key, Ramrod Key, Saddlebunch Keys, Sugarloaf Key, and Summerland Key) within the Florida Keys. Five mosquito species were collected: Aedes aegypti, Culex nigripalpus, Cx. quinquefasciatus, Cx. ...

A 20-month-old child was accidentally poisoned after biting through the bottom of a medicine container and ingesting the tablets inside. Consequently a study was carried out to determine the force required to fracture 20 randomly selected 25 and 32 ml polystyrene containers to see whether this exceeded the bite force of a child's jaw. Tests were performed at displacement rates of 0.5 and 10 cm/...

BACKGROUND Recent reports suggest that endocrine disruptors may leach into the contents of bottles made from polyethylene terephthalate (PET). PET is the main ingredient in most clear plastic containers used for beverages and condiments worldwide and has previously been generally assumed not to be a source of endocrine disruptors. OBJECTIVE I begin by considering evidence that bottles made fr...

Biochemical and physical changes of two types of fresh-cut fruits packaged in plastic containers and stocked at 4°C were studied over a period of six days. The first type of container was film-lidded and contained orange juice, pomelo, kiwifruit and orange slices. The second type was plastic-lidded and contained orange juice, apple, kiwifruit and orange slices. Color, vitamin C and carbohydrate...

Reforestation is needed globally to help restore degraded sites, combat desertification, protect watersheds, and provide forest products. This involves planting forest tree seedlings grown in local nurseries, but technologies to produce quality seedlings are lacking in developing countries. Modern nursery containers used to propagate seedlings have internal-surface barriers (ribs or ridges) or ...
