the main objective of a research program, whose output is presented here, has been to estimate “ventilation coefficients”, a critical parameter in determining air pollution concentration near the surface ground which signifies the ability for natural ventilation of an air shed in an urban or rural area. relevant measured data from the city of tehran has been used to calibrate and further de...

Fragmentation and convergence are two discoursal lenses that have been used to view changes that have taken place in the domains of legal services, the legal profession, regulation and legal education. While they may appear orthogonal, the relationships between them are intimate, sophisticated, constantly shifting and require much more analysis. In this paper I shall argue that law schools need...

Anaerobic microbial processes play particularly important roles in the biogeochemical functions of wetlands, affecting water quality, nutrient transport, and greenhouse gas fluxes. This study simultaneously examined nitrate and sulfate removal rates in sediments of five southwestern Michigan wetlands varying in their predominant water sources from ground water to precipitation. Rates were estim...

Correlations have been developed for implementation into the semi-empirical Predictive Code for Aircrew Radiation Exposure (PCAIRE) to account for effects of extremum conditions of solar modulation and low altitude based on transport code calculations. An improved solar modulation model, as proposed by NASA, has been further adopted to interpolate between the bounding correlations for solar mod...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...

the current study reports some interesting growth of novel in2o3 nanostructures using ambient-controlled chemical vapor deposition technique in the presence of a strongly reducing hydrazine ambient. the experiments are systematically carried out by keeping either of the carrier gas flow rate or the source temperature constant, and varying the other. for each of the depositions, the growth is st...

We consider an inspection game between an arbitrary number of polluting rms and an agency who can choose to monitor ambient pollution. We obtain an equilibrium where all rms comply with the same probability and where the inspection agency inspects all rms individually if ambient pollution exceeds an endogenous threshold. If the ne for noncompliance is high enough, the agency's costs are lower t...

Developments in oral and maxillofacial radiology affect almost every aspect of dentistry: some change the legal framework in which Canadian dentists practise; some re-emphasize established standards of care, such as the dental radiologist's mantra, ALARA (using a dose that is as low as reasonably achievable) and viewing images in reduced ambient lighting. Developments in the legislation that re...
