Among the horticulture facilities in Korea, hydroponic cultivation method has been increasingly used. This study aimed to identify fungi and bacterial species highlight need for sterilization recycle discharged drainage. Samples were collected from a number of paprika, tomato, strawberry greenhouses. Vinyl glass greenhouses studied, drainage discharge was two types: direct collection after disc...
In the present study, basin morphometry of Hirehalla Sub-basin Bagalkote District, Karnataka was carried out using remote sensing and geoinformatics techniques. Delineation calculation various morphometric parameters sub-basin done in GIS environment. The study categorized into– Linear, Aerial Relief aspects. Result obtained from analysis confirms highest order fifth showing sub-dendritic to de...
[1] The High Plains Aquifer (HPA), underlying parts of 8 states from South Dakota to Texas, is one of the largest fresh water aquifers in the world and accounts for 30% of the groundwater used for irrigation in the US. Determining the distribution of HPA’s hydraulic conductivity (K) is critical for water management and addressing water quality issues. K is traditionally estimated from well pump...
We examined the survivorship of Anopheles gambiae s.l. Giles (Diptera: Culicidae) larvae and habitat productivity in three major habitat types in the western Kenya highlands. The age-specific distribution was determined for larvae and pupae, and survivorship curves were constructed. Larval-to-pupal survivorship was 6.8% in drainage ditches, 4.3% in cow hoofprints, and 1.8% in disused goldmines,...
The sub-Himalayan thrust belt is an active thrust wedge which progresses southward over the northdipping Indian plate. The north–south compression resulted in severe deformation of sedimentary rocks in this belt. Distinct thrust geometries and topography have evolved under the interaction between tectonic and erosional environments. To better understand the relationship between tectonics and to...
Resourcesat-1 LISS-IV Mx satellite imagery was used for detailed geomorphological and hydrogeological study of Karawan watershed. For morphometric analysis, ASTER data was used for preparing digital elevation model and GIS was used in evaluation of linear, areal and relief aspects of morphometric parameters. Watershed boundary, flow accumulation, flow direction, stream ordering; and contour, sl...
Introduction The vertical and horizontal movements of the Earth crust have caused extensive changes in surface phenomena, in the active tectonic regions. In order to measure some of these changes, morphometry analyses have been used to evaluation of the amount of tectonic activity. These analyses are useful tools for analyzing existing feature at the ground level and provide a proper understan...
The research in the fields of irrigation and drainage network in the province Hamidieh to evaluate the performance of drainage was done in the land. For this purpose, three drainage server farm at intervals of 50, 70 and 80 meters in the area was selected. Blank observation on three drain pipes at intervals of 0.3,0.8,1.5,2.5 and 15 meters of lateral drains in the middle of the line in four row...
this report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. success rate was 90%. infected collections were successfully drained in 94% and noninfected collections in 72% . partial success was achieved in two pati...
sub basin prioritization is one of the integrated watershed management and sustainable development strategies. to protect natural resources, through marking zones of potential damage in small areas for is a primary need sustainable development. degradation potential zones project for watershed protection measures is not cost-effective economically. so this is a prerequisite for sub basin priori...
