An extreme analysis for the 2010 precipitation event at the South of Saskatchewan Prairie
General
After a prolonged drought period in the early 2000s, the Canadian prairie experienced a remarkably wet year in 2010. Five stations near the edge of the Saskatchewan boreal forest recorded historically high cumulative precipitation (from April to September). The exceptional wet year causes the public...
Effect of calcium cyanamide on pathogenic escherichia coli during mesophilic composting and impact on composting process
General
The objective of the study was to determine the effect of CaCN2 on pathogenic E. coli as an antimicrobial agent and its impact on composting progress as an amendment in dairy cow manure based mixtures composted at laboratory scale. The changes in physical parameters, chemical parameters and...
Ammonia removal from fertilizer plant effluents by a coupled electrostatic shielding based electrodialysis / electrodeionization process
General
Electrically and ionically conducting graphite powder beds interposed between the anode and cathode inside an electrolytic setup are used as intermediate bipolar electrodes. The beds cause electric field discontinuity by eliminating the applied electric field locally within their mass and act as...
Temporal variability of disinfection by-products concentration in urban public water system
General
The occurrence of trihalomethanes (THMs) was studied in the drinking water samples from urban water supply network of Karachi city that served more than 18 million people. Drinking water samples were collected from 58 locations in summer (May-August) and winter (November-February) seasons. The major...
Thermal comfort estimation in relation to different orientation in mountainous regions in Greece by using artificial neural networks
General
This study focuses on the estimation of thermal comfort conditions in a high alt. site (1455 m) in Apodotia (MA), Greece, by using the MLP neural network model. This estimation is based on the air temperature (t) and relative humidity (f) data of the middle (1078-1163 m) and of the low altitude...
Neural network estimation of the scour cone geometry around outlet in the pressure flushing
General
When flushing carry out as pressure condition, a scour cone is performed around the outlet. As the flow around the outlet in the pressure flushing is three dimensional, therefore that it is difficult to establish a general empirical model to provide accurate estimation for scour cone volume and...
Development of a regional model for hydropower potential in western Greece
General
A regional model was developed in the present study for the determination of the flow duration curve at ungaged catchments, in western and northwestern Greece, which is a hydrologically homogenous region. A flow duration curve indicates the water availability at a site and is important for the...
Regional climate change scenarios for Greece: future temperature and precipitation projections form ensembles of RCMs
General
The potential regional future changes in seasonal (winter and summer) temperature and precipitation are assessed for the greater area of Greece over the 21st century, under A2, A1B and B2 future emission scenarios of IPCC. Totally twenty-two simulations from various regional climate models (RCMs)...
Changing mediterranean environment: irrefutable evidence from pre-industrial, unpublicised scenes contemporary with a mission (1786-1787) in the Levant
General
This paper provides an introduction to one hundred thirty one, pre-industrial, unpublicised Mediterranean scenes kept in Oxford, which constitute valuable evidence of changing environment. The largely unknown and unpublished paintings witness environmental wilderness and the cultural landscapes of...
Solar assisted photo fenton for cost effective degradation of textile effluents in comparison to AOPS
General
Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD...
