A square sheet of aluminum foil is considered 2-dimensional because its mass is proportional to its diameter to the power of 2. A solid aluminum sphere is considered 3-dimensional because its mass is proportional to its diameter to the power of 3. An aluminum wire is considered 1dimensional because its mass is proportional to its length. The mass is proportional to length to the power of 1. Fro...
this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion were...
abstractof two mcall programs introducing 100 vocabulary items through two im the researcher of the present study was intrigued to compare the effects age modalities (pictures and streaming video) with those of a conventional method (teacher instruction) in an efl context. she set out to investigate whether such multimedia environments could provide a more effective environment for vocabulary...
A local hospital was interested in shielding some sensitive equipment and contemplated installing a shielded room. The room under consideration was the typical laminated wood core panel with galvanized steel on both surfaces, with a RF shielded door, honeycomb air vent panels and filters for ac power, telephone and any other signals, meeting the shielding effectiveness requirements of MIL-STD-2...
This study compared Mallinckrodt® Laser-FlexTM with polyvinyl chloride endotracheal tubes (ETTs) wrapped with aluminum foil tape, copper foil tape, or Merocel® Laser-Guard laser-resistant wrap to determine ifspecular reflection occurred during exposure to a carbon dioxide (co2) laser. The ETTs were straightened and centered within cardboard cylinders and exposed to a laser set at 25 W for a max...
in this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. the influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final ph and energy consumption rate was determined. dye removal was increased with increases in solution ph, current density and contact tim...
Background & Objectives: In this study, treatability of wastewater from a laundry unit was investigated by applying electrocoagulation method in which two pairs of aluminum and iron electrodes were utilized. Electrocoagulation is a noble treatment method suitable for different kinds of wastewater which has been given a considerable attentions by researchers recently. Applying direct current to ...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
a particles emitted from an Am radioactive source at energies of 5.4 MeV generate bursts of about ten electrons when passing through an aluminized Mylar foil. Besides the typical surface barrier electrons, the energy spectra of the secondary electrons clearly reveal two additional peaks. One at 66 eV is ascribed to aluminum LVV Auger electrons and another at 10.5 eV is attributed to the decay o...
