Ester derivatives of low molecular weight heparin are disclosed. These derivatives exhibit improved Anti-Xa activity in relation to global anticlotting activity.

Low molecular weight heparin derivatives having improved anti-Xa

Ester derivatives of heparin are disclosed. These derivatives exhibit low anti-Xa activity in relation to global anticlotting activity.

Heparin derivatives having decreased anti-Xa specificity

Acetyl ester derivatives of heparin are disclosed. These derivatives exhibit improved Anti-Xa activity in relation to their global anticlotting activity.

Heparin derivatives having improved anti-Xa specificity

Heparin derivatives containing hydrophobic groups and exhibiting improved permeability are disclosed. Said derivatives exhibit anticoagulant activity and improved solubility in organic solvents.

Heparin derivatives with improved permeability

Low molecular weight heparin derivatives containing hydrophobic groups and exhibiting improved permeability are disclosed. Said derivatives exhibit anticoagulant activity and improved solubility in organic solvents.

Low molecular weight heparin derivatives with improved permeability

An irrigation system is moved with an oscillating trojan bar operating against a lugged wheel. A drive pawl on the trojan bar drives the wheel forward on level ground or uphill. A hold-back pawl on the trojan bar keeps the wheel from running free when going downhill. The detent likewise contains an uphill pawl and a downhill pawl.

Two-step roll ahead irrigation system

A pivot or circle type irrigation system has a single hydraulic cylinder upon each vehicle to provide motive force to that vehicle. Two hydraulic tubes extend the length of the system and each hydraulic tube is connected to one side of each cylinder without valves. The cylinder movement is blocked if the vehicle upon which it is mounted is detected to be ahead by an alignment system. Hydraulic fluid is pumped into one tube until an increase of pressure indicates that all of the cylinders are cockablock and then the tubes are reversed and hydraulic fluid is pumped into the other line until, again, a rise in pressure indicates that all of the cylinders are cockablock.
