The subgrade soil is the foundation plate form of the roadway; it should sustain its structural characteristics throughout the design life of the roadway with minimal requirements for maintenance. When Gypseous soil is implemented in the construction of subgrade, problems regarding collapsibility and poor structural capacity usually occur when the subgrade came in touch with excess water. Asphalt stabilization could furnish a proper solution to such problems. In this investigation, an attempt has been made to monitor the variations in compressibility characteristics of asphalt stabilized subgrade soil subjected to 30 cycles of (freezing-thawing) and (heating-cooling). Data have been observed after each 10 cycles, and compared with that of reference mix. Specimens of (75) mm diameter and (20) mm height have been prepared at optimum fluid content with various asphalt emulsion percentages. Testing was carried out using the standard odometer to determine the compressibility characteristics at dry and soaked test conditions. It was concluded that for samples exposed to (10, 20 and 30) cycles of (freezing-thawing), the compression index (Cc) had increased with the increase of cycles in soaked condition but it decreases with increased number of cycles in dry condition. Initial void ratio decreased with number of cycles in dry condition; but remains constant with increased number of cycles in soaked condition. For samples exposed to (10, 20 and 30) cycles of (heating-cooling), (Cc) decreased with the increase of cycles in both soaked and dry condition. Initial void ratio increased with number of cycles while it slightly changed for dry and soaked condition respectively.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"44 1","pages":"11-19"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83703574","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 microscopic investigations revealed that the textural relationships between barite and iron minerals are complicated, resulting in a difficult liberation during the comminution process. XRD analysis of the studied ore indicated the presence of hematite and goethite as the dominant iron minerals and barite, quartz and halite as gangue minerals. Chemical assays using XRF showed that the investigated ore contains 42.29% Fe2O3 (29.58% Fe total), 36.99% BaO and 16.95% SO3. The pre-treatment operations involved crushing and milling up to -150μm particle size. The processing operation included chemical leaching of 15 gm representative sample of the ground ore using acidic medium of HCl at fixed agitation speed 900 r/m. The leaching was followed by filtration, solvent extraction and precipitation processes. The resultant dual concentrate is divided into iron fraction containing 66.11% Fe with 99.84% iron recovery and barite concentrate containing 66.85% BaO (99.81% recovery) and 30.53% SO3 (99.47% recovery). The resultant iron fraction is accepted as a blast furnace feed charge for the Egyptian Iron & Steel Company, while barite fraction can be used for the oil industry and glassmaking.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"37 1","pages":"20-26"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89784821","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}

Studies suggested that maternal and neonatal complications of gestational diabetes mellitus can be reduced by diet and life style modification, treatment with oral hypoglycemic agent and insulin. The present study was performed to compare the maternal and neonatal consequences in gestational diabetes mellitus patients, those treated with metformin with those treated with insulin. Retrospective study was performed including 31 gestational diabetes mellitus patients treated with metformin and 31 gestational diabetes mellitus patients treated with insulin. It was found that there was no difference between metformin treated patients and insulin treated patients regarding maternal outcomes (body mass index, pregnancy induced hypertension, preeclampsia, candidiasis etc.). Cesarean deliveries were significantly higher in metformin treated group than in insulin group (p<0.05). Forty eight percent GDM patients treated with metformin group underwent cesarean section. The frequency of full term live birth was higher in insulin group than in metformin group (p<0.001). Fifty five percent patients treated with metformin stay at hospital more than 24 hours. There was no difference between the groups in other neonatal outcomes (preterm live birth, macrosomia, still birth, miscarriage, respiratory distress syndrome etc.). The only incidence of neonatal hypoglycemia was higher in insulin group. The data of present retrospective study suggests that there was no major difference in maternal and neonatal outcomes in metformin and insulin treated GDM patients, both drugs showed good glycemic control in GDM patients which resulted in reduction of maternal and perinatal complications, furthermore insulin was not associated with the higher incidence of cesarean section, post natal stay at hospital and preterm live birth compare with metformin.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"32 1","pages":"64-68"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90829575","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}

Jaeg. and Entodon plicatus C. Muell. (Bryopsida). In preluded phytochemical analysis cardiac glycosides, flavonoids, saponins, anthroquinone, terpenoids, tannins, phenolic, proteins, fats and fixed oils were observed by using standard tests. It was found that E. plicatus contains more amount of phytochemicals than H. involuta. The antioxidant activity of both the plants was also determined according to standard protocols and appealing results were found. Comparative analysis was done for the activity of Catalase, Peroxidase, Ascorbate peroxidase, Glutathione reductase and Superoxide dismutase and interesting observations were made. Antimicrobial activity of methanolic extracts of both the plants was evaluated against Bacillus subtilis, B. cereus and Escherichia coli by using the Agar well diffusion method. Extract of H. involuta showed a greater inhibitory activity than Entodon plicatus.

Numerous studies have proven that aspirin reduces the signs and symptoms of inflammation and exhibited a broad range of pharmacological activities, including analgesic, antipyretic and antiplatelet properties. Previous studies suggested that beside the pharmacological activities aspirin was also associated with the side effects and toxicity of various doses and in various formulations. The present study is performed to explore the effects of aspirin in various doses (75mg (EC), 100mg, 150 (EC)mg and 300mg) in different preparation (enteric coated (EC), non-enteric coated) on liver enzymes (Serum glutamic oxaloacetate transaminase (SGOT) and Serum glutamic pyruvic transaminase (SGPT)) followed by daily administration for 10 days and for 30 days. We found that the SGOT level was increased by all doses of aspirin after 30 days of treatment, this effect was most significant at 75mg (EC) and 100mg dose, whereas at 150mg (EC) and 300mg was not very significant. The level of SGPT was decreased by all doses regardless of duration of treatment, only 75mg (EC) dose increased its level after 30 days of treatment, suggesting 75mg (EC) aspirin could be hepatotoxic due to lessen of anti-oxidant effects, furthermore suggests that patients with hepatic insufficiency should not receive 75mg (EC) dose of aspirin.","PeriodicalId":14310,"journal":{"name":"International Journal of Scientific Research in Knowledge","volume":"5 1","pages":"28-32"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87270535","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}
