Methylglucoside (MEG) has been used in the water-based mud with fine montmorillonite (MMT) swelling inhibition, but it still has such shortages as large concentration and low thermostability. In this work, carboxymethyl glucoside (CMG) was synthesized with glucose and sodium chloroacetate and used as swelling inhibitor. The inhibition of CMG against clay swelling was investigated by MMT linear ...

Mathematical knowledge has reached a size when it has become extremely hard to organize. A new method to organize mathematical knowledge is through representing mathematical theories in a computer system. There are several languages that can organize mathematical knowledge. We will focus on the MMT language that provides a web scalable module system for mathematical theories. In MMT the theorie...

MMt can be divided into two parts, homogeneous and heterogeneous, dependant on whether the models we deal with are of the same or different types (metamodels). The most important issue in heterogeneous MMt is model translation, and the most difficult problem in abstract MMt is how to specify it in a generic way (so that, for example, transformations of ER-diagram into an SQL schema and the latt...

The Mmt language has been developed as a scalable representation and interchange language for formal mathematical knowledge. It permits natural representations of the syntax and semantics of virtually all declarative languages while making Mmt-based MKM services easy to implement. It is foundationally unconstrained and can be instantiated with specific formal languages. The Mmt API implements t...

OBJECTIVES To assess the clinical effectiveness and cost-effectiveness of buprenorphine maintenance therapy (BMT) and methadone maintenance therapy (MMT) for the management of opioid-dependent individuals. DATA SOURCES Major electronic databases were searched from inception to August 2005. Industry submissions to the National Institute for Health and Clinical Excellence were accessed. REVIE...

OBJECTIVES Methadone maintenance treatment (MMT) effectively reduces illicit opioid use and its negative consequences when patients participate in and adhere to treatment. Patients' participation and adherence may relate to their perceptions about methadone doses and dose adjustments and the meanings that patients associate with treatment. This study assessed patient perceptions about methadone...

background and objectives: preparation and evaluation of nanocomposite films have become prevalent in recent years. depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. the effects of montmorillonite (mmt), glycerol (gl), and thei...
