Abstract: A novel combination of five queen-produced mandibular gland substances which can be used for controlling worker retinue formation around or in place of a honey bee queen Apis mellifera L. is disclosed. The composition comprises: 9-keto-2(E)-decenoic acid, R-(-)- and S-(+)-9-hydroxy-2(E)-decenoic acid, methyl p-hydroxybenzoate, and 4-hydroxy-3-methoxyphenylethanol. Each component more or less is generally weakly active alone, but the blend of five compounds in a ratio corresponding to their occurrence in gland extracts imparts activity equivalent to queen mandibular extract at a level as low as 10.sup.-7 of that present in a queen. This blend of compounds initiates the retinue response, which includes the licking and antennating behaviour that signals the presence of a dominant reproductive queen, and thereby establishes and stabilizes the social fabric of the colony.

Abstract: A water-soluble diammonium compound, such as N-methyl-N-(2-hydroxyethyl)-N-tallowalkyl-N'-methyl-N'-bis(2-hydroxyethyl) -propylene-diammonium methosulfate, is homogeneously and finely dispersed in a spray-dried detergent bead or granule. The spray-dried bead is blended with a clay mineral fabric softener. The final composition exhibits antistatic action even at low levels (e.g. less than 2%) of the antistat without adversely effecting softening, cleaning or whitening. In a typical formulation, the spray-dried beads include linear alkyl benzene sulfonate or other anionic surfactant, an inorganic polyphosphate and/or other inorganic and/or organic detergent builder salt, diammonium compound antistatic agent, and other heat stable and pH insensitive detergent additives and fillers.

Abstract: A superconductive material with a superconducting critical temperature of at least 77.degree. K. comprising 20 at. % Nb, 10 at. % Si, 10 at. % Al and 60 at. % O is provided by simultaneous vapor-phase physical deposition or sputtering of Nb, Si and Al onto a heated sapphire substrate under oxygen-containing atmosphere, followed by a rapid quenching or post-oxidization of Nb-Si-Al ternary system composition having an Nb/Si/Al atomic ratio of 2/1/1. The high critical temperature allows abundantly existing, cheap available liquid nitrogen to be used as a cryogen for developing superconductivity.

Abstract: A sealer for filling a dental root canal which can seal the apex of the root and the root canal perfectly and can be removed with the gutta percha points when refilling is necessary.The sealer of the invention consists of the same basic material as the gutta percha point, so it adheres to the point initimately and firmly and can seal the apex of the root perfectly. The softening temperature of the sealer is about 40.degree.-45.degree. C., so the points and the sealer can be removed same time by heating at low temperature with a heat carrier when refilling is necessary.

Abstract: Aqueous peroxide bleaching compositions that include surfactant, fluorescent whiteners and dyes are effectively stabilized by the addition of a heavy metal chelating agent and a free radical scavenging agent. Both agents must be present to achieve maximum stability. Particularly preferred chelating agents are the amino polyphosphonates. Particularly preferred free radical scavenging agents are the hydroxybenzenes and especially substituted phenols. Not only is the peroxide oxidizing agent stabilized, but surfactant, fluorescent whitener, and dye as well.
