摘要:
A weighting agent composition for use in a cement slurry for downhole operations in a subterranean well, the composition comprising a finely divided solid weighting agent; and a dispersant comprising a sulphonic acid, salt or derivative thereof, the sulphonic acid having the general formula I: -[A(OSOO−M+)-B-A′(OSOO−M+)]n- (I) wherein A and A′ are each an aromatic moiety; B is an aliphatic moiety; OSOO−M+ is a solubilising group consisting of sulphonic acid, a salt or derivative thereof; and n is an integer of at least 2. The composition is of particular use in formulating a cement slurry for use in a downhole cementing operation. There is also provided a method of preparing a finely divided weighting agent using the sulphonic acid of formula I, a cement formulation comprising the composition and a method of cementing a subterranean well.
摘要:
A system and method in a network-based inventory management system for providing information concerning inventory amounts and inventory ordering to at least one computer. In operation, a server first receives an inventory amount of an item from a first plurality of clients. Next, the server receives an inventory amount of the item from a second plurality of clients. Once the server has the two amounts, it analyzes the inventories at said first and second plurality of computers to determine from which of the first plurality of computers to order the item and to which of the second plurality of computers the ordered item is to be transferred.
摘要:
The invention provides a method for removal of an excess of a liquid metal coating from a substrate, such as a hot dip coated metal substrate, and in preferred embodiments, for control of metal coating thickness.The method involves moving the substrate through a stationary pulsating or alternating magnetic flux. The flux is directed in a path which enters the coating at an entry zone and exits from the coating at an exit zone, those zones being on the external surface of the coating and spaced apart in the direction of advance of the substrate. The frequency and intensity of the flux are controlled so as to exert on the coating surface a force opposing the viscous drag forces exerted in the coating by the moving substrate. Apparatus for use in performing the method is described.
摘要:
The present invention relates to dianilinopyrimidine derivatives, compositions and medicaments containing the same, as well as processes for the preparation and use of such compounds, compositions and medicaments. Such dianilinopyrimidine derivatives are useful in the treatment of diseases associated with inappropriate Wee1 kinase activity.

A computing environment can dynamically respond to user preferences and personal abilities by enabling computer users to configure their computing experience by implicitly gathering information about the users' needs. The system can detect users' issues during the natural course of interaction with the system and offer to make adjustments to make their tasks simpler and more enjoyable. The system can allow for the configuration of settings that can impact users' abilities to receive important information from the system or provide input to the system.
摘要:
A treatment apparatus and method for wellbore instability is described including a caliper with one or more radially extending arms which are capable of extending and retracting movement in a radial direction and a fluid supply facility to deliver treatment fluid from the ends of the arms to the wellbore wall, with a sensing and valve mechanism such that in use fluid is being delivered from the end of any extended arm to a breakout region of the wellbore where there is instability.
摘要:
The disclosed invention is a composition of matter, a process of production thereof, and a method for the treatment of chronic pain, especially to the treatment of heretofore intractable pain as associated with advanced cancer, neurological conditions and rheumatoid arthritis. The treatment of pain associated with viral infections and lesions are also within the contemplation of the present invention. The composition of matter comprises modified alpha-neurotoxins or modified venoms known to contain alpha-neurotoxins in an acceptable carrier for either parenteral, oral or topical administration.
摘要:
The invention provides improved methods of making compositions comprising detoxified neurotropically active modified neurotoxins derived from snake venom, and compositions made using these methods. The compositions are useful for the treatment of a wide variety of neurological and viral diseases.
摘要:
The present invention relates to a class of proteins, and a method for treatment of neurological and viral diseases in humans and animals. More specifically it applies to the treatment of heretofore intractable diseases such as retro-viral infections including human immunodeficiency virus (HIV), simian immunodeficiency virus (SIV), feline immunodeficiency virus (FIV), bovine immunodeficiency virus (BIV) and equine acquired immunodeficiency virus (EAIV). The method of treatment comprises administering to the subject a disease mitigating amount of a detoxified modified venom composition.
