Chinese fir is a tall, fast-growing species that is unique to southern China. In Chinese fir plantations, successive plantings have led to a decline in soil fertility, and aluminum toxicity is thought to be one of the main reasons for this decline. In this study, Non-invasive Micro-test Technology was used to study the effect of aluminum stress on the absorption of 4 different ions in the roots...

Although aluminum excess is an apparent pathogenetic factor underlying osteomalacia in dialysis-treated patients with chronic renal failure, the mechanism by which aluminum impairs bone mineralization is unclear. However, the observation that aluminum is present at osteoid-bone interfaces in bone biopsies of affected patients suggests that its presence at calcification fronts disturbs the cellu...

Needless to say that the combined lot sizing and cutting stock problem is very relevant in a wide range of manufacturing industries. This paper presents an algorithmic solution approach to overcome the difficulty in solving non-linear integer formulation of the problem. The algorithm is based on the traditional approach where the lot sizing is determined for each period, and then the best cutti...

Aluminum foam has received considerable attention in various fields and is expected to be used as an engineering material owing to its high energy absorption properties and light weight. To improve the mechanical properties of aluminum foam, combining it with dense tubes, such as aluminum foam-filled tubes, was considered necessary. In this study, an aluminum foam-filled steel tube, which consi...

Zeolites, having widespread applications in chemical industries, are often synthesized using organic templates. These can be cost-prohibitive, motivating investigations into their role in promoting crystallization. Herein, the relationship between framework structure, chemical composition, synthesis conditions and the conformation of the occluded, economical template tetraethylammonium (TEA+ ) ...

Peel tests are widely used to characterize the peel strength of bonded joints and control adhesion quality. There various configurations test, such as T-peel testing at 180°, floating roller climbing drum test. These methods have been mainly in aeronautical industry, a way assessing metallic joints. However, with growing use composite materials it is necessary these when subjected peeling loads...

After WW2, a huge market opened in the growing economies and cemented carbides contributed as tool materials and construction parts to their industrial development. Today, cemented carbides are the workhorses in all areas of the manufacturing industries: no factory without cemented carbide tools; no production of glass bottles, aluminium cans or plastic tubes which has not benefited from these ...

BACKGROUND The aim of this study was to evaluate the effects of Korean Red Ginseng marc with aluminum sulfate as litter amendments on ammonia, soluble reactive phosphorus, and pathogen populations in poultry litters. METHODS Increasing levels of Korean Red Ginseng marc with aluminum sulfate were applied onto the surface of rice hull as a top-dress application; untreated rice hulls served as c...

Porous alumina film on aluminum with gel-like pore wall was prepared by a two-step anodization of aluminum, and the corresponding gel-like porous film was etched in diluted NaOH solution to produce alumina nanowires in the form of densely packed alignment. The resultant alumina nanowires were reacted with NH(3) and evaporated aluminum at an elevated temperature to be converted into densely pack...
