despite the lack of a clear understanding of the relationships of eastern and southeastern arabia with different iranian regions during pre-sassanian era and the paucity of written evidence from this period, the huge corpus of archaeological evidence obtained from this region and the few available historical documents show that the region maintained close contacts with iran and was under legal ...

Representative bed material samples were taken from the two gauging sites on rivers omi for sieve analysis to obtain the grain size distribution of its bed materials. The analyses of the grain size distribution showed that the bed load accounted for 9% of the total estimated suspended sediment load of 1,703, 548.113 kg/annum in river omi. River omi bed material had a geometric mean particle siz...

Introduction Understanding the jetting phenomena near the gas distributor plate in a fluidized bed is important to gassolids mixing, heat and mass transfer, and erosion on any bed internals, which can all affect the performance of the bed. Moreover, acoustic vibration in a fluidized bed can be used to enhance the fluidization quality of particulate matter. Visualizing the jetting structure usin...

RECENT investigations of the conjunctival and nail-bed microcirculation indicate that certain changes in the small blood vessels and the circulating blood are frequently associated with disease. Straight, unkinked arterioles, tortuous veins, and micropools have been observed by Landau and Davis' in subjects with arteriosclerosis. Congestion of the venules and capillaries are seen in diabetes me...

Groups of starved, virgin adult male or female bed bugs were stimulated to search for a host by the presence of a heated artificial feeder. Some of the bed bug groups were allowed to obtain a blood meal and some were not. After the removal of the feeder, bed bugs were observed throughout the scotophase to record their searching and aggregation behavior. Groups of male and female bed bugs that w...

Bed bugs Cimex lectularius L. were exposed to conidia (spores) of the entomopathogenic fungus Metarhizium anisopliae by feeding, aerosol spray, or contact with a treated surface. Feeding experiments demonstrated that bed bugs were innately susceptible to this fungus. However, only at 98% humidity were mortality rates high, regardless of whether bed bugs were sprayed with a fungal solution or co...

Fluidized bed is commonly used for struvite (MgNH4PO4·6H2O) recovery from wastewater. However, effective methods are lacking to describe the properties of the millimeter-scale struvite pellets in the fluidized bed, with the consequence of not predicting and optimizing the granulation process effectively. In this work, swine wastewater was used as the medium for struvite recovery by using fluidi...

Thermal conversion of automotive shredder residue (ASR) using indirect fluidized bed gasification was conducted in the Chalmers semi-industrial 2–4-MWth gasifier. The material consisted olivine that activated through deposition biomass ash prior to a 13-day exposure ASR. interactions between and ASR were investigated XRD, SEM-EDS, thermodynamic modeling. iron (Fe) onto particles noted, this is ...
