Aluminium balance studies were carried out on eight patients with various immunological disorders who were receiving plasma exchange with albumin solutions known to be contaminated with aluminium. Four patients with impaired renal function (creatinine clearance less than 50 ml/min) retained between 60% and 74% of the aluminium infused during a single plasma exchange. Transiliac bone biopsy spec...

the aim of the present study was to examine anthropometric characteristics and selected physical fitness factors in male elite athletes (epee, foil, sabre) of iran national fencing team. the statistical population consisted of 30 athletes of fencing national team (age range 22.2± 3.67 yr) in the three weapons (epee n=10, foil n=10 and sabre n=10). anthropometric characteristics (sitting height,...

It is of burgeoning importance that the human body burden of aluminium is understood and is measured. There are surprisingly few data to describe human excretion of systemic aluminium and almost no reliable data which relate to aluminium in sweat. We have measured the aluminium content of sweat in 20 healthy volunteers following mild exercise. The concentration of aluminium ranged from 329 to 5...

The fluid dynamics of many swimming and flying animals involves the generation and shedding of vortices into the wake. Here we studied the dynamics of similar vortices shed by a simple two-dimensional flapping foil in a soap-film tunnel. The flapping foil models an animal wing, fin or tail in forward locomotion. The vortical flow induced by the foil is correlated to (the resulting) thickness va...

‘THEUSE of heavy aluminum foil in our ashing procedure for PB1 (1), introduced 3 years ago, has proved extremely successful in preventing cross-contamination. A Temco double-door muffle furnace is used for which three steel buckets were made; small buckets, 4 in. wide, 6 in. long, and 6 in. deep, and one large bucket, 6 in. wide, 8 in. long, and 6 in. deep. A steel shovel was made to aid the te...

Chronic renal failure leads to secondary hyperparathyroidism; the spontaneous evolution of this entity results in high bone remodelling. However, throughout the last decades we have learnt that several medical interventions, particularly those which involve a high degree of aluminium exposure, may change the evolution of secondary hyperparathyroidism, leading to other diseases such as aluminium...

In this study, an addition of Ag micro-particles (8–10 lm) with a content in the range between 0 and 1.5 wt.% to Sn–9Zn eutectic solder, were examined in order to understand the effect of Ag additions as the particulate reinforcement on the microstructural and mechanical properties as well as the thermal behavior of the newly developed composite solders. Here, an approach to prepare a micro-com...

In an earlier paper, [5], I gave semantics and tableau rules for a simple first-order intensional logic called FOIL, in which both objects and intensions are explicitly present and can be quantified over. Intensions, being non-rigid, are represented in FOIL as (partial) functions from states to objects. Scoping machinery, predicate abstraction, is present to disambiguate sentences like that ass...
