The invention is directed to methods and compositions for reducing the deposition of pitches and stickies in a papermaking process. The method involves introducing an anionic glycerol-based polymer to the papermaking process. This anionic polymer prevents the pitches and stickies from depositing and agglomerating in papermaking processes.

The present invention relates to an amyloid β peptide analogues comprising an amino acid sequence or a peptidomimetic thereof, wherein the sequence (i) forms a loop, (ii) has at least 66% identity to the amino acid sequence of native Aβ peptide or a portion thereof, (iii) comprises at least 6 contiguous amino acid residues and (iv) has at least 2 non-contiguous amino acid residues which are covalently linked with each other, oligomers comprising a plurality of said amyloid β peptide analogues, processes for preparing the amyloid β peptide analogues or oligomers, compositions comprising the amyloid β peptide analogues or oligomers, and uses of the amyloid β peptide analogues or oligomers such as their use for treating or preventing an amyloidosis (e.g. by active immunization), for diagnosing an amyloidosis, and for providing agents that are capable of binding to the amyloid β peptide analogues or oligomers. The subject invention also describes agents that are capable of binding to the amyloid β peptide analogues or oligomers, e.g. antibodies, compositions comprising the agents, and uses of the agents such as their use for treating or preventing an amyloidosis (e.g. by passive immunization) and for diagnosing an amyloidosis.

In the mining of minerals from the earth, it is necessary to drill deep bore holes typically between 3000 and 6000 feet in the earth. In order to protect those entering the hole for additional mining operations, after drilling the hole, the hole is lined with a stack of specially constructed lining segments. These segments are formed of either prestressed concrete or steel. The segments are lowered one at a time into the bore hole so as to build up a stack within the hole, thereby lining the hole. The segments are carried to the hole on a transporter and then lowered by the transporter into the hole. Guide cables are threaded through guide conduits provided within the segments so as to maintain the orientation of such segments during the operation. The weight of the segment as it is lowered is supported by fluid, normally the drilling mud, that fills the hole and the transporter until the segment comes into contact with the top of the uppermost segment on the stack of those segments already placed into the hole. Grout is then placed between the lining segments and the inner wall of the bore hole. The grouting process is periodically carried out after every few segments have been placed into the hole. After the lining operation has been completed, the miners can enter the bore hole for other mining operations.

Minerals, in particular coal, that have been deposited in layers or along seams in the earth can be mined utilizing a large diameter bore hole drilling equipment. With the drilling equipment stationed on the surface of the earth, a drilling member is drilled down into the earth along the seam of the mineral deposit. If the mineral deposit extends at an angle to the earth, i.e. less than 90.degree., the drilling operation is conducted so as to drill at a similar angle to the earth. As the mineral deposits are broken up during the drilling operation, the broken fragments are removed from the drilled hole. After drilling has occurred for a certain distance in a forward direction, a creeping effect is induced in portions of the side walls of the drilled hole. The drilling member is then retracted from the drilled hole in such a manner so as to drill out any mineral fragments in the hole of the drilling member. These mineral fragments are then removed from the hole as the drilling member is retracted. The removal of the mineral fragments can best be accomplished utilizing an hydraulic flow mechanism for circulating fluid through the drilling member and removing the mineral fragments as they are drilled.

Systems and methods for managing canisters used to automatically dispense medication are provided. Canisters are configurable via a design process and a build process to accurately dispense a variety of medications. Design profiles are created and stored by a canister management system, and are federated to workstations used to build and fill the canisters, and to workstations used to dispense the medication. Information related to the build process, the fill process, and the dispense process is also federated by the system. The system also enables the transmission of other types of messages between client applications on the workstations and the canister management system. The system is useful to federate data regardless of a structure of a supply chain used to design, build, distribute, and use the canisters.

The present invention is directed to orally disintegrating dosage forms comprising lipid coated substrates and silicified excipients. The use of silicified excipients in the orally disintegrating dosage form along with lipid coating of active agents, allows for improvements in the ability to prepare these dosage forms. Further, the dosage form can prevent unpleasant taste or aftertaste and provide better chemical and mechanical stability of the coated active substrate. This present invention also provides the possibility of harder more durable tablets, along with targeted immediate or modified release profiles for the active agent.
摘要:
In the mining of various minerals from the earth, large mining shafts extending from the surface down to the deposited mineral layers or seams in the earth can be provided through the use of large diameter bore hole drilling equipment. With the drilling equipment stationed on the surface of the earth, a drilling member is drilled down into the earth for forming a shaft in excess of 10 feet to a depth of at least 2000 feet. As the earth is broken up during the drilling operation, the broken fragments are removed from the drilled hole by a reverse circulation drilling operation. During the drilling operation, the drilling bit is maintained in proper alignment with the shaft being drilled by the use of non-rotating stabilizers having an outer diameter substantially equal to the diameter of the hole being drilled. By maintaining fluid at a sufficient level in the drilled hole during the drilling operation, an adequate hydrostatic head can be created for exerting an opposing pressure on any zone of instability on the walls of the drilled hole for preventing inflow of water and debris.
