BACKGROUND Habitat modifications resulting from human transportation and power-generation infrastructure (e.g., roads, dams, bridges) can impede movement and alter natural migration patterns of aquatic animal populations, which may negatively affect survival and population viability. Full or partial barriers are especially problematic for migratory species whose life histories hinge on habitat ...

This paper presents a systems life cycle and a structured design method which are tailored towards the construction of real-time systems in general, and hard real-time systems in particular. The standard systems life cycle is modified to take into account the expression and satisfaction of non-functional requirements. The HOOD design method is extended to support abstractions which explicitly c...

To increase containment efficiency and reduce energy consumption, a sash-less, variable-height inclined air-curtain fume hood (sIAC hood) was developed and tested by a laser-assisted flow visualization technique and tracer-gas detection method. This novel design requires neither sash nor baffle. The sIAC hood employed the inclined push-pull air-curtain technique and two deflection plates instal...

The study was conducted on 20 farm workers to identify the occupational health hazards in threshing operation. Four different protective masks were given and tested on various parameters. Respondents reported respiratory health problems which were mainly due to heat and organic dust in the surroundings. All respondents reported irritation in eyes and throat followed by nose (85.0%) and ears (75...

Cooking is a major contributor to indoor particulate matter (PM) concentrations. Studies suggest that cooking-generated PM rapidly disperses even when range hood in operation, suggesting hoods fail perform sufficiently used isolation. However, the performance of can be improved by supply make-up air equivalent airflow rate hood. This study evaluates prevention dispersion and discharge ventilati...

The extensor apparatus, an aponeurosis that covers the dorsal side of each finger, transmits force from a number of musculotendons to the phalanges. Multiple tendons integrate directly into the structure at different sites and the extensor apparatus attaches to the phalanges at multiple points. Thus, prediction of the force distribution within the extensor apparatus, or hood, and the transmissi...

For distributed and parallel computing the new version of HOOD, HOOD4 [1], brings a significant advantage: it decouples the logical design from the partitioning required to map software onto a net of processors. The HOOD Run-Time Support System (HRTS), introduced for HOOD4, will support an engineer to distribute the software. With the HOOD4 approach a software engineer can concentrate on the re...
