In order to lower fuel consumption and reduce emissions, aluminum is being considered as an alternative to steel in large scale production of autobodies. This study evaluates the prospects of aluminum sheets as a cost efficient alternative to steel in autobodies with the unibody design. The study focuses on the processing technologies and alloy selection for aluminum automotive sheets and looks...

The treatment of spent oil-in-water emulsion (SOWE) from a non-ferrous metal-processing plant by using aluminum sulfate and hydrated lime was studied in order to determine the purification efficiency, optimize the operating conditions and scale up the treatment process. The purification efficiency was estimated by comparing the compositions of the SOWE and the processed wastewater. The treatmen...

Natural dye extracted from Caesalpinia sappan Linn. was applied to a cotton fabric and silk yarn by dyeing process. The dyestuff component of Caesalpinia sappan Linn. was extracted using water and ethanol. Analytical studies such as UV–VIS spectrophotometry and gravimetric analysis were performed on the extracts. Brazilein, the major dyestuff component of Caesalpinia sappan Linn. was confirmed ...

Metallic monoliths were prepared by anodized aluminum-scale pilot plant, using sulfuric acid as electrolyte. Anodisation tests were conducted at different times and different temperatures of the electrolytic bath. Aluminum monolith anodized at 40oC for 30 min was selected for catalysts support. The monoliths were impregnated by two methods: i) impregnation in two stages using two Mn salts in an...

The main source of seed filling results from the photosynthesis green tissue closest to sinks in capitula. To evaluate role different leaf strata and capitula yield its components Safflower genotypes, a field study was performed as factorial experiment based on RCBD 3 replicates East Azarbaijan Agricultural Natural Resources Research Education Center 2008. used factors this were: two genotypes ...

A system for the regeneratlon of caustic soda solutlons used In etching aluminum Invokes the hydrolysis of sodium aluminate to llberate free sodium hydroxide and produce a dry, crystalllne hydrated alumlna byproduct. The system has been used extenslvely In Japan, and, by adjusting process parameters, can be adapted to North American practice. By otlllting the system in a typical plant, soild ai...

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

32P-Postlabeling analysis and enzyme-linked immunosorbent assay (ELISA) have been used to detect DNA adducts in peripheral blood lymphocytes from primary aluminum production plant workers who were exposed occupationally to a mixture of polycyclic aromatic hydrocarbons (PAHs). Preliminary results reported here are from a comparative study being performed in two aluminum plants. The levels of aro...

Acidic soils are distributed worldwide, predominantly in tropical and subtropical areas, reaching around 50% of the arable soil. This type of soil strongly reduces crop production, mainly because of the presence of aluminum, which has its solubility increased at low pH levels. A well-known physiological mechanism used by plants to cope with Al stress involves activation of membrane transporters...

Several studies reported many neurodegenerative disorders and Alzheimer' disease induced by aluminum chloride on cerebral cortex of male rats. Coriander (Coriandrum sativum) is a plant among others which improve blood circulation to the head, impart mental concentration and memory capabilities. Coriander, both its leaves and its seeds are grown as spice group all over the world. The present inv...
