Syntax: Substitution and Binders

Cement is a binding material, a substance that sets and hardens independently, and can bind other materials together. In ancient civilization the binding materials were of traditional type such as jaggery, lead, jute, rice husk etc, now in modern civilization cement is main binding materials. The use of concrete containing high volume fly-ash has recently gained popularity as a resource efficie...

The language of relation algebras is expanded with variables denoting individual elements in the domain and with the ↓ binder from hybrid logic. Every elementary property of binary relations is expressible in the resulting language, something which fails for the relation algebraic language. That the new language is natural for speaking about binary relations is indicated by the fact that both C...

Reinforced concrete based on ordinary Portland cement (OPC) is one of the most commonly used materials in modern buildings. Due to global growth building industry, components have been partially or completely replaced with waste that can be as binders aggregates. Besides ecological aspects, architecture widely needs make durable, resisting large loads and various detrimental forces environment....

Because of an elevated serum phosphate level, patients who suffer from chronic kidney failure frequently tend to have cardiovascular calcification and are therefore exposed to a higher probability of a fatal event. Phosphate binders are able to reduce these negative effects. Currently, there are primarily two groups of phosphate binders (calcium-containing and calcium-free phosphate binders) wh...

In normal serum, saline dialysis for 48 hours in Visking casing resulted in folate clearance closely comparable to that produced by haemoglobin-coated charcoal adsorption, except in kwashiorkor where charcoal removed a greater proportion of folate. Pre- and post-dialysis values probably represented total and bound folate, respectively. Urinary folate consisted almost exclusively of dialyzable o...

In order to build green mines, goaf is often filled, supported, and sealed with a high-water material eliminate series of environmental problems safety hazards caused by goaf. this study, ordinary Portland cement, sulphoaluminate alkali-activated cement were used as binders prepare full-tailings materials for filling, various water-to-cement ratios. The compressive strength development consolid...

BACKGROUND Phosphate binders, such as lanthanum carbonate, control elevated serum-phosphate levels in patients with end-stage renal disease (ESRD). Lanthanum carbonate is available in oral powder and tablet form. The aim of this survey was to investigate satisfaction with, preference for, and adherence to lanthanum carbonate oral powder in patients with ESRD. SCOPE Patients from France and Sp...

Higher-order logical frameworks provide a powerful technology to reason about object languages with binders. This will be demonstrated for the case of the-calculus with two diierent binders which can most elegantly be represented using a third-order constant. Since cases of third-and higher-order encodings are very rare in comparison with those of second order, a second-order representation is ...
