Aluminium-based water treatment residual (Al-WTR) is the most widely generated residual from water treatment facilities worldwide. It is regarded as a by-product of no reuse potential and landfilled. This study assessed Al-WTR as potential phosphate-removing substrate in engineered wetlands. Results indicate specific surface area ranged from 28.0 m(2) g(-1) to 41.4 m(2) g(-1). X-ray Diffraction...

The reduction of aluminium trichloride by lithium aluminium hydride in the presence of poly(vinylpyrrolidone) or poly(methylmethacrylate) in mesitylene yielded nano aluminium particles in the matrices of respective polymers. Solution phase synthesis methodology was used successfully to produce composites of various Al/polymer ratios. The composites were characterized by powder XRD patterns and ...

The aluminium alloys are more frequently used in automotive industry especially as an alternative material for car-bodies. In this article the comprehensive summary concerning technology of resistance spot welding of aluminium alloys was presented. The welding schedules, electric parameters of welding, electrodes materials and electrodes life time by resistance spot welding aluminium were descr...

Buckwheat genus (Fagopyrum Mill.) is one of the aluminium tolerant taxonomic units of plants. The aim of the study was an evaluation of the aluminium (50 μM effect on phenolic accumulation in various parts of buckwheat plants (Fagopyrum esculentum Moench). Detection of increasing of total phenolic content, changes in flavonoid and anthocyanin content and phenylalanine ammonia-lyase activity (PA...

The experiments were conducted to determine effects of precocious vaccination compared to the classical schedule of vaccination and of Chinese herbal adjuvant (CHA) on immune response to vaccine against rabbit hemorrhagic disease (RHD) in young rabbits. In experiment 1, five New Zealand rabbits at 30, 35, 40 or 45 days of age were injected with 3 ml of non-adjuvant inactivated vaccine against R...

Corkwing wrasse (Symphodus melops L.), a protogynous, non-migratory lipfish species, living close to rocky shores was chosen as an indicator species for the monitoring of biological effects of contaminants. Fish were caught by local fisherman at the Norwegian west coast in fjord sites within the framework of the EU BEEP project. The sites represented different point source impacts of (I) copper...

Glasses and glass-ceramics (GCs) used for sealing, coating and high voltage applications belong to a special class of materials in which among other requirements, matching of thermal expansion coefficient with that of metal as closely as possible up to set temperature is an important consideration. In this paper I shall concentrate on some indigenous efforts carried out in my laboratory on the ...

Molecular dynamics (MD) has been used to identify the relative distribution of dysprosium in the phosphate glass DyAl(0.30)P(3.05)O(9.62). The MD model has been compared directly with experimental data obtained from neutron diffraction to enable a detailed comparison beyond the total structure factor level. The MD simulation gives [Formula: see text] correlations at 3.80(5) and 6.40(5) Å with r...

Abstract Nanoscaled-VPO (vanadium phosphate oxide) catalysts have been prepared on an alumina support with the objective of obtaining crystallites active phase a high surface-to-volume ratio. Since catalysed reaction occurs at surface, these nanoscaled allows studying surface species transformations minimized signal from bulk dominion. The chemical environment and oxidation state has determined...

The aim of the study was to evaluate the protective status of an antioxidant combination (melatonin and Sempervivum tectorum extract) on aluminium accumulation in genital organs of male rats. The 12 weeks study was carried out on 35 Wistar male rats divided in five groups: C – control, receiving distillated water; E1 – aluminium sulphate 0.1 mg/L; E2 – melatonin 10 mg/kg b.w. in drinking water;...
