The in-line development of crystalline morphology and orientation during melt extrusion of low density polyethylene (LDPE) tape at nil and low haul-off speeds has been investigated using Small-Angle X-Ray Scattering (SAXS). The processing parameters, namely haul-off speed and distance down the tape-line have been varied and the resulting crystalline morphology is described from detailed analysi...

The demand for natural gas (NG) in Thailand has been continuously increasing, but part of NG volume not distributed to customers locating far from the pipeline network. Therefore, is transported by trucks liquid form called liquefied (LNG) meet demand. However, road transportation truck causes many problems such as high cost, low capacity, poor environmental conditions, and safety. To solve the...

RECENT investigation of samples labelled zaratite from the Lord Brassey Mine, near Heazlewood, Tasmania, in the mineral collection of the Museum of Victoria revealed the presence of the rare nickel carbonate, otwayite, and the rare nickel hydroxide, theophrastite. X-ray diffraction, electron microprobe and infrared analysis were utilised in the study, which failed to confirm the presence of zar...

OBJECTIVE US long-haul truck drivers experience a wide array of excess cardiometabolic disease (CMD) risks unique to their occupation. How these risks translate to, and potentially induce, elevations in the clinical CMD risk profile of this population is unknown. METHODS A non-experimental, descriptive, cross-sectional design was employed to collect anthropometric and biometric data from 115 ...

λ2 OC-192 We are manufacturing widely tunable laser diodes based on an integrated single chip design. The sampled-grating distributed Bragg reflector (SG-DBR) laser is monolithically integrated with a semiconductor optical amplifier (SOA). The continuous wave (cw) output power of the fully packaged device is more than 20mW over the entire C-band with low noise figures and a high side-mode suppr...

Trucking has been classified as one of the highest-risk occupations in the United States. Occupational stress is even greater for long-haul truckers who are away from home, family, friends, and other support networks for several days or weeks at a time. Occupational stressors and the mental health of truckers was studied using data collected as part of a large multisite ethno-epidemiological st...

BACKGROUND Drivers of heavy and tractor-trailer trucks accounted for 56% of all production and nonsupervisory employees in the truck transportation industry in 2011. There are limited data for illness and injury in long-haul truck drivers, which prompted a targeted national survey. METHODS Interviewers collected data during 2010 from 1,670 long-haul truck drivers at 32 truck stops across the ...

In order to reduce the serious problem associated with the mining of important supply f communication roads by hostile parties during peace keeping operations, the Canadian Department of National Defence has recently begun the development of a multi-sensor teleoperated mine detection vehicle, the Improved Land-Mine Detection Capability (ILDC). One sensor identified as a serious candidate for th...
