Kroytar's story, or his childhood memories, are then related to two small children - Illgnar and Randal, son and daughter of King Helmbrecht - to give them a perspective. A winged dragonborn warblade warlord, one of the strongest of the Asgardian order, introduces, in the introduction of the.Cataleptogenic actions of atrial natriuretic peptide in the rat.
The effect of atrial natriuretic peptide (ANP) on blood pressure, heart rate, plasma catecholamines and heart rate variability in urethane-anaesthetised, paralysed rats was examined. ANP (0.03-10 micrograms/kg s.c.) caused dose-related increases in blood pressure and heart rate. These effects were paralleled by increases in plasma noradrenaline and adrenaline. The amplitude of the low-frequency component of heart rate variability increased at lower doses of ANP, whereas the high-frequency component was reduced. These results suggest that ANP is a potent pressor and chronotropic agent in the rat. The effects on plasma catecholamines and heart rate variability are consistent with a direct action of ANP on the central nervous system.The present invention relates to a ladder accessory attachment of the type that removably attaches a ladder to an object.
In some instances, there is a need to attach a ladder to a stationary object. For example, an electrician may be installing a ceiling fan fixture in a ceiling cavity, and a ladder is needed to reach the ceiling.
In an example of a prior art attachment, a ladder attachment has a first and second plate each having an opening therein for receiving a threaded rod that is attached to the ladder. The plates can be attached to the ceiling and the ladder can be attached to the plates by passing the threaded rod through the openings in the plates and rotating the threaded rod to lock the plates on the ladder and ceiling.
Some of the disadvantages of the prior art attachments are that the attachment cannot hold the ladder securely, the attachment must be held in place by two hands, it is time consuming to install the attachment, and it is difficult to separate the ladder from the attachment when it is desired to remove the ladder.
In view of the foregoing, it is a general object of the present invention to provide a ladder attachment that overcomes the disadvantages of the prior art.
It is another object of the present invention to provide a ladder attachment ac619d1d87
