Abstract We performed a laboratory investigation at 1,873 K using MoSi 2 furnace to study the effect of refractories on inclusions in 55SiCr suspension spring steel. Three types crucible materials (Al O 3 , MgO·Al and MgO–CaO) were investigated. The results this indicated that SiO Al not suitable for making By contrast, MgO–CaO was perfect choice producing advantages crucibles smelt steel summa...

The aim of this study was the assessment of exposure to ultrafine in the urban environment ofLisbon, Portugal, due to automobile traffic, and consisted of the determination of deposited alveolar surface area in an avenue leading to the town center during late spring. This study revealed differentiated patterns for weekdays and weekends, which could be related with the fluxes of automobile traff...

The social transformations brought about by the mobile internet are extensive. In discussing the broad range of these transformations—positioned as a shift from personal computing to pervasive computing—this editorial elaborates on the key contributions addressed by the articles in this special issue of Future Internet. These articles touch on topics such as the digital divide, the role of the ...

An incorrect engine oil pressure gauge and an sensor will provide false indications of low or high pressure. Standard sensors work by displaying a warning signal when the falls outside set range. Two important components to include spring-loaded switch diaphragm. The is connected diaphragm that exposed Pressure indicator can be diagnosed using DMM inspect visually on block. Good type helps ECU ...

Nowadays, many industries are shown interest in the hybrid composites, natural fibers, and reinforced materials due to reduction of weight. The reason is that it will not affect environmental conditions. This experimental investigation identified mechanical properties composites. composite extensively used by E-glass/epoxy, carbon, titanium alloy. Composites have good strength less highest chal...

In recent years, the automobile industry has primarily concentrated on reducing weight and improving ride quality. Because composite materials have a high strength-to-weight ratio, strong corrosion-resistance, tailorable qualities, Steel leaf springs are being phased out in favour of automotive industry. Three strategies been investigated to reduce vehicle weight: rationalizing body structure, ...

Walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.Today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...
