As a major source of water for irrigation, the evaluation and assessment groundwater to ensure it meets quality sustainable agriculture is key. This research presents findings its suitability irrigation purposes. was carried out using indices Geographic Information System (GIS). The Inverse Distance Weighted (IDW) method GIS used study spatial distribution these indices. Indices considered incl...
Abstract Groundwater is an important source for drinking water supply in Jabalpur District, Madhya Pradesh, India. An attempt has been made this work to understand the suitability of groundwater human consumption. The parameters pH, Electrical Conductivity (EC), Copper (Cu), Chromium (Cr), Sulphate (SO4), Iron (Fe), Nitrate (NO3), Chloride (Cl), Total Hardness (TH), Alkalinity (TA), and Sodium ...
Th e arable weeds (segetal fl ora) were explored on Plešivica hills (NW Croatia) during vegetational seasons 2002 and 2003 at 10 locations. Th e common methods of plant recording, collecting and identifi cation were applied in the research of the arable weeds. Th e nomenclature of plants was according to Tutin et al. (1964-1980, 1993). Th e total of 107 taxa of arable weeds that classifi ed to ...
This present hydrological study assessed the groundwater quality of Biratnagar Metropolitan by application Water Quality Index (WQI). It has been determined on basis analyzed samples for some important physicochemical parameters such as pH, turbidity, electrical conductivity (EC), dissolved oxygen (DO), free carbon-dioxide (FCO2), bicarbonate (HCO3), total hardness (TH), phosphate (PO4-P), nitr...
The assessment of the suitability and status irrigation water quality from aspect its potential negative impact on soil salinization mapping spatial distribution within area three Morava rivers, which includes South, West, Great basins, was purpose this research. A total 215 samples were tested, their evaluated based analysis following parameters: pH, electrical conductivity (EC), dissolved sal...
Abstract This study presents an assessment of groundwater quality over the two constituent districts (Faridabad and Gurgaon) National Capital Region (NCR), India, using geospatial statistical approaches. These have been subjected to rapid urbanization industrialization in recent years. The parameters viz., pH, electrical conductivity (EC), carbonate (CO 3 2? ), bicarbonate (HCO ? chloride (Cl s...
Effects of saliva and nasal secretion on some physical properties of four different resin materials.
OBJECTIVE Aim of this study was to evaluate possible effects of saliva and nasal secretion on some physical properties, such as sorption, solubility, surface hardness and colour change on four different resin-based materials over a certain time period. METHODS A total of 128 disc-shaped specimens with a diameter of 50 mm and thickness of 0.5 mm were tested to evaluate sorption and solubility ...
STATEMENT OF PROBLEM Variations in light-polymerizing parameters, such as light intensity and light-to-material distance, may affect the physical characteristics of polymerized resin. PURPOSE The purpose of this study was to characterize the relation between total light energy and the final hardness of 4 composites polymerized under varying conditions. MATERIAL AND METHODS Four commercial c...
A three factor three level central composite design was adopted to determine interactive effects of meat level (55-65%), steaming time (12-18 minutes) and drying time (7-9 hrs) on pH, moisture, protein content, fat content and other quality characteristics (Hardness, adhesiveness, total colour change and overall acceptability) of extruded chicken noodles. Moisture, protein, fat level and total ...
