However, the scaling theory approach has also proven to be an effective method to describe the variation of soil hydraulic properties. The objective of this study was to evaluate the structure of spatial variability in soil hydraulic and hydrologic processes using scaling techniques in the Plantations Section of the Department of Crops and Soil Sciences, KNUST, Kumasi. Field infiltration studies were conducted using the single ring infiltrometer. Saturated hydraulic conductivity (Ks) was determined in the laboratory by the falling head permeameter. The similar media theory approach was employed in the scaling of Ks, while cumulative infiltration amount (I) was scaled using the linear variability theory. Scaling factors and parameters of the reference curves were computed directly from the parameters of individual soil hydraulic and hydrologic parameters and reference curves were obtained to represent Ks and I in the field. Scaling factors ranged from 0.23 to 2.66 with a mean of 1.00 for Ks, I and cumulative time. The composite Ks and I for the study area calculated by using different, but related, scaling factors was successful, though the distribution and range of the parameters were highly variable.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"7 1","pages":"224-232"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89769599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amount of dry matter produced per unit of nitrogen applied or absorbed can be judged by estimating the nitrogen use efficiency of different nutrient sources used for tomato cultivation. The present experiment was aimed to examine the effect of 15 different combinations of organic and inorganic nutrient sources on growth and yield attributes, nitrogen use efficiency and soil nitrogen balance. The result revealed that tomato growth and yield attributes as well as different parameters of nitrogen use efficiency (PFP, AE, PUE and AR) were remarkably influenced by the application of different sources of nutrients. Substitution of 25% of recommended fertilizer dose was possible when higher amount of organic manures and biofertilizer were combined together. Vermicompost emerged as better organic nutrient source over farmyard manure. Inoculation with biofertilizer exerted more positive result over uninoculated treatments and benefits of biofertilizer application were prominent in presence of vermicompost. The nutrient schedule comprising of 75% recommended fertilizer dose of inorganic fertilizers and vermicompost (4 t/ha) inoculated with biofertilizer was found best for growth, yield attributes as well as the NUE parameters and soil nitrogen balance. This should be practiced to achieve desired yield, nutrient use efficiency and sustaining the fertility and productivity of soil.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"58 8","pages":"233-240"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91399427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gypseous soil obtained from Al-Fallujah was subjected to laboratory investigation. The physical and chemical properties and then optimum liquid asphalt (emulsion) requirement were determined. A laboratory soil embankment-model of 50x50x30 cm was implemented to study the impact of absorption by capillary rise on the stability of embankment. Load repetitions test was carried out on four gypseous soil models, two of them were pure soil at dry and absorbed conditions, and the other two were stabilized with emulsion at dry and absorbed condition. Another set of four gypseous soil models of the same condition were tested under static load. The impact of changing the hydraulic conductivity of soil due to asphalt stabilization was investigated and the vertical deformation was determined using LVDT. For the pure soil in dry condition the vertical deformation was 7.45 mm at 157 load repetitions, while for pure soil model under absorbed condition, the vertical deformation was 12.5 mm at 29 load cycles. The stabilized soil at dry condition exhibits vertical deformation of 9.75 mm at 911 load cycles, and shows 10.47 mm deformation at 897 load cycles under absorption. When tested under static load, the ultimate sustained pressure was 0.8 MPa with vertical settlement 0.03 mm for pure soil at dry condition, and reduced to 0.3 MPa with vertical settlement 12 mm at absorbed condition.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"5 1","pages":"241-248"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88858477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a disease known to cause sudden vision loss. The intraocular fluid fails to drain so the drainage mechanism of the eyes gets blocked. Fluid starts building up and so the pressure inside the eyes starts increasing. The optic nerves get effected and the vision is lost. The medication is given in the form of eye drops sometimes followed by surgery. Alpha-adrenergic agonists are an important class of the medications given for glaucoma treatment including brimonidine and apraclonidine. Apraclonidine has been found to be effective (0.5-1% concentration) in lowering intraocular pressure. Its efficacy has been checked against acetazolamide, brimonidine, timolol and dorzolamide and the drug has shown promising results. It has shown greater hyotensive effect as compared to other medications and its drops have been reported to exhibit corneal biomedical response. The present review aims to cover the studies done in the last ten years on the effectiveness of apraclonidine but still a lot of work needs to be done in checking its potential with beta-blockers, other alpha-adrenergic agonists and other classes of glaucoma medication.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"21 1","pages":"208-214"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81725980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

African nations have different attitudes towards cultural regeneration and dissemination as the continent struggles to address the ambiguous role and position of culture as it forge ahead with her development agenda and find her position in the global information revolution. It is essential for African countries to ensure that adopting ICT for development (ICT4D) does not destroy their beautiful cultural heritage. Culture is passed from one generation to another through inheritance as young generation is brought up in it, thus, growing up to appreciate and passes it on to their children. However, at such a time when the world is drastically embracing information age, the value of culture may easily be lost. African conservatives and elders are worried that their children are losing their \"good\" traditions and culture. In the evolution of the information society, particular attention must be given to the special situation of indigenous peoples, as well as to the preservation of their heritage and their cultural legacy. In this regard, this paper attempts to address the following issues: how do we adopt ICT4D in Africa yet keep our culture and heritage? And how we use ICT to preserve Africa\"s culture?

The morphology of the fans and their watershed is quantitatively described through estimated morphometric parameters. For relationships between geomorphological features of the fans and their drainage basins, self-organizing maps (SOM) were used. In SOM, according to both qualitative data and morphometric variables, the clustering tendency of alluvial fans was investigated using 15 alluvial fans parameters. The results of the analysis showed that several morphologically different fan types were recognized based on their geomorphological characteristics in the study area. A strong positive relationship was found between the drainage basin area and size of the fan with a simple power function.
