Experimental Behavior of Laced Reinforced Concrete One Way Slab under Static Load
...Show More Authors

Test results of eight reinforced concrete one way slab with lacing reinforcement are reported. The tests were designed to study the effect of the lacing reinforcement on the flexural behavior of one way slabs. The test parameters were the lacing steel ratio, flexural steel ratio and span to the effective depth ratio. One specimen had no lacing reinforcement and the remaining seven had various percentages of lacing and flexural steel ratios. All specimens were cast with normal density concrete of approximately 30 MPa compressive strength. The specimens were tested under two equal line loads applied statically at a thirds part (four point bending test) up to failure. Three percentage of lacing and flexural steel ratios were used: (0.0025, 0.0045 and 0.0065). Three values of span to effective depth ratio by (11, 13, and 16) were considered, the specimens showed an enhanced in ultimate load capacity ranged between (56.52% and 103.57%) as a result of increasing the lacing steel ratio to (0.0065) and decreasing the span to effective depth ratio by (31.25%)  respectively with respect to the control specimen. Additionally the using of lacing steel reinforcement leads to significant improvements in ductility by about (91.34%) with increasing the lacing steel ratio to (0.0025) with respect to the specimen without lacing reinforcement.

Determination of some Optimum Conditions for Bioremediation of Some Heavy Metals by Saccharomyces cerevisiae: Determination of some Optimum Conditions for Bioremediation of Some Heavy Metals by Saccharomyces cerevisiae
...Show More Authors

The study aimed to determine of some Optimum conditions for bioremediation and removing of seven mineral elements included hexavalent chromium, nickel, cobalt, cadmium, lead, iron and copper as either alone or in group by living and heat treated cells of baker’s yeast Saccharomyces cerevisiae. The dried baker's yeast from Aldnaamaya China Company was used in this study. Biochemical tests was used to ensure yeast belonging to S. cerevisiae and then used to remove the mentioned mineral elementes under different conditions which included incubation period, pH, and temperature. It was found that the best of these conditions was 60 minutes for duration of incubation, 6 for pH, 25 ᵒC for temperature. During the study the behavior of living
