We analyze a model of interactive unawareness introduced by Heifetz, Meier and Schipper (HMS). We consider two axiomatizations for their model, which capture different notions of validity. These axiomatizations allow us to compare the HMS approach to both the standard (S5) epistemic logic and two other approaches to unawareness: that of Fagin and Halpern and that of Modica and Rustichini. We sh...

most of the targeted heavy metals (hms) in sewage sludge ended up in solid residues after pyrolysis and gasification, such as Cu, Zn, Cr, Ni and Pb, which their residual rates were over 70%. The bioavailability of the hms in residues decreased despite their concentrations being higher compared with in sludge. The potential eco-toxicity of each HM were ceased after pyrolysis and gasification of ...

OBJECTIVE Hazmat disaster preparedness is critical, especially as Hong Kong prepares for major international events, such as the 2008 Olympic Equestrian Games. No published medical study describes the identities and quantities of hazardous materials (HMs) in Hong Kong and lists what antidotes are needed for these dangerous goods (DGs). This study describes what HMs are most common in Hong Kong ...

Heavy metals (HMs) in sewage sludge have become the crucial limiting factors for land use application. Samples were collected and analyzed from 32 waste water treatment plants (WWTPs) in the Shanxi Province, China. HM levels in sewage sludge were assessed. The multivariate statistical method principal component analysis (PCA) was applied to identify the sources of HMs in sewage sludge. HM pollu...

Hydrothermal treatment (HTT) at 200°C was applied to immobilize heavy metals (HMs) and the effect of rice husk (RH) addition was investigated based on total HMs concentration, fractionation and leaching tests. The results indicated that a synergistic effect of RH addition and HTT could be achieved on reducing the risk of HMs from medium and low risk to no risk. Metals were redistributed and tra...

The purpose of the study was to investigate the mineralogical and Heavy Metals (HMs) present in the granite mining soils in Chimakurthy, India. The mineral exploration of mining soils were identified by X-Ray Diffractometer (XRD) pattern analysis. However, the morphological features and quantitative HMs were detected by Scanning Electron Microscopy/Energy Dispersed Spectroscopy (SEM/...

The number of patients living with hematological malignancies (HMs) has increased steadily over time. This is the result of intensive and effective treatments that also increase the probability of infiltrative, infectious or toxic life threatening event. Over the last two decades, the number of patients with HMs admitted to the ICU increased and their mortality has dropped sharply. ICU patients...

BACKGROUND Sfax is a very industrialized city located in the southern region of Tunisia where heavy metals (HMs) pollution is now an established matter of fact. The health of its residents mainly those engaged in industrial metals-based activities is under threat. Indeed, such workers are being exposed to a variety of HMs mixtures, and this exposure has cumulative properties. Whereas current HM...

Task reassignments in 2D mesh-connected systems (2D-MSs) have been researched for several decades. We propose a hierarchical 2D mesh-connected system (2D-HMS) in order to exploit the regular nature of a 2D-MS. In our approach priority-based task assignments and reassignments in a 2D-HMS are represented by tableaux and their algorithms. We show how task relocations for a priority-based task reas...
