The invention is a system and method for handling items to be shipped that securely verifies the sender. The invention makes use of pre-printed, unique, labels which are affixed by hand or machine to items to be mailed or shipped. These labels are packaged and distributed in groups. The groups of labels can be sold or freely distributed. Each person or organization that originates shipments is assigned a unique customer account number and their identity is authenticated when this account is created. The group number for a group of labels is linked to a customer account prior to the use of any of the labels from the group. The linking can be done at the time of sale or distribution of the group of labels, or after the sale or distribution thereof. Post-sale linking of a group of labels to a customer account can be done over the phone or through a web-site. The invention overcomes limitations in the prior art by creating a method for authenticating the sender of each item without requiring the use of a computer, printer, postage machine, or any other specialized hardware by the sender. The unique label identifiers are stored in a database that is used to ensure that each label that can be used only once. The invention is suitable for bulk mail processing and individual mail items. The invention provides a method for making selective use of specialized handling equipment, including equipment to irradiate the mail to destroy biological agents.

A novel method is set out of preparation of radioactive diagnostic radiopharmaceutical in a stable, shippable, lyophilized form by an apparatus designed to rapidly flash freeze and dehydrate a radiopharmaceutical composition to minimize auto radiolysis. The method proposes rapid cooling and removal of ambient vapor, and then ultra cold removal when the potential of explosive liquid oxygen is eliminated. The radioactive diagnostic radiopharmaceutical requires no further cold or refrigerated storage, including with respect to shipping, subsequent to stabilization. The preferred composition can be reconstituted “on site” by the addition of a suitable diluent to bring the radiopharmaceutical complex into solution at a desired concentration.

An aqueous binder composition is provided that includes a protein-containing biomass and a pH adjuster. Optionally, a crosslinking agent and / or a moisture resistant agent may be included in the binder composition.

The crosslinking agent may be any compound suitable for crosslinking the protein-containing biomass and reacting with the moisture resistant agent, when the moisture resistant agent is present in the binder. In addition, the binder has a light color after it has been cured. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats.

The invention is a wedge-shaped support adapted to be fastened to a user's lower leg to provide comfort when the user is kneeling on an inclined roof, used in pairs. Each shin wedge comprises a wedge of lightweight material capable of supporting the user's weight. The acute dihedral angle of each wedge is approximately equal to the pitch angle of the roof on which the wedge kneepads are being used, thereby providing a substantially horizontal upper kneeling surface when the wedge is oriented towards the peak of the roof. The wedge's lower surface typically comprises a durable pad that prevents premature abrasion of the lightweight material and improves grip onto the inclined surface. Each wedge's upper surface typically includes a soft layer that serves as an ergonomic kneeling pad for the user. An attachment harness secures the wedge kneepad to the user's shin and thigh or knee.
