Abstract Diesel particulate matter (DPM) is an area of concern from environmental point view due to its functionality settle in the respiratory channels when inhaled, cause inflammation tract, accumulate carcinogenic compounds, and adversely reflected cardiovascular functions, thus causing excess mortality. DPM consists agglomeration a numerous unions preimages germ structures, spherical form t...

The aim of this work is to evaluate the characteristics of activated and non-activated carbon obtained from carbon-enriched coal fly ashes (CECFA) from two different power stations to be used in the low temperature reduction of NO from stack gases. Carbon-rich fractions were obtained by mechanical sieving of fly ashes and by oil agglomeration. Activation of some samples was carried out in steam...

This research provides a theoretical conceptualization of SOA governance aspects that can be used to assess SOA governance practices and provide guidance to improve them. The review of IT and SOA governance shows that there are conflicting claims and inconsistency in the literature concerning the role of SOA governance. Moreover, there is no empirical evidence on the implications of the governa...

in this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. the engines are assumed to be implemented as composite web services. current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. the difficulty is to rollback the execution state of the workflo...

We show that the chemical structures of silicone oils can have an important role in the giant electrorheological (GER) effect. The interaction between silicone oils and solid nanoparticles is found to significantly influence the ER effect. By increasing the kinematic viscosity of silicone oils, which is a function of siloxane chain length, sol-like, gel-like and clay-like appearances of the con...

Economic research on industry location and agglomeration has focused nearly exclusively on manufacturing. This paper shows that services are prominent among the most agglomerated industries, especially at the county level. Because traditional measures of knowledge spillovers, natural resource inputs, and labor pooling explain little of agglomeration in services industries, this paper takes an a...

We study the packing fraction of clusters in free-falling streams spherical and irregularly shaped particles using flash X-ray radiography. The estimated is low enough to correspond coordination numbers less than 6. Such numerical simulations aggregates that collide grow without bouncing. Moreover, irregular evolved faster formed larger sizes with lower fraction. This result on granular suggest...

Calcium-dependent protein kinase (CDPK) is expressed in sandalwood (Santalum album L.) seeds under developmental regulation, and it is localized with spherical storage organelles in the endosperm [Anil et al. (2000) Plant Physiol. 122: 1035]. This study identifies these storage organelles as oil bodies. A 55 kDa protein associated with isolated oil bodies, showed Ca(2+)-dependent autophosphoryl...

In Haiti, wood and wood charcoal are common fuels for cooking. This practice has contributed to deforestation, leading to erosion and fatal floods. The availability of charcoal made from a different source other than wood, such as agricultural waste, might provide Haitians with an alternative, more sustainable fuel, which in turn may reduce fuel prices. MIT students have developed various metho...
