An improved golf tee for being used upon a golf course; the tee being made of a substance such as grass seed or plant food and a carrier material such as cellulose that serves as a binder to hold the substance together when molded into tee shape; the tee after becoming broken or lost in use on the golf course promoting grass growth, thus eliminating becoming scattered debris while at a same time improving the ecology.

A diamond film is grown on a substrate by providing a non-diamond substrate which has a face-centered cubic (fcc) crystal structure and small crystal lattice mismatch with the lattice of diamond, implanting carbon atoms into the crystal lattice of the substrate and causing the implanted carbon atoms to diffuse out of the substrate and grow epitaxially on the surface of the substrate. The preferred substrate is an fcc metal such as copper, nickel, fcc iron, fcc cobalt or fcc chromium.

Growth promotion in animals is achieved by administration of 1-methyl-5-nitroimidazol-2-methyl carbamate in feed and/or water.

.beta.-Phenethanolamines are effective in promoting growth and improving feed efficiency and leanness in animals.

A panel (10) for use as a side wall of a plant growth container is disclosed. In one embodiment the panel (10) comprises an elongate cuspated sheet (11) having apertures formed in at least some of the outwardly projecting cusps to facilitate air root pruning of the root structure of a plant grown within the container. The sheet (11) includes a non-cuspated edge section (12), the non-cuspated edge section (12) being co-operable with a complementary edge section (13) of the same sheet (11) or of a…

The invention provides a mass of crystals, particularly diamond crystals, having a size of less than 100 microns and in which mass the majority of the crystals are faceted single crystals. The invention further provides a method of producing such a mass of crystals which utilizes crystal growth under elevated temperature and pressure conditions, the supersaturation driving force necessary for crystal growth being dependent, at least in part, on the difference in surface free energy between low M…

This invention provides a process and apparatus for the growth of biomass from a supply of suitable nutrient wherein the volume of biomass and the size and shape of the units in which it is present within a vessel (10) in which the reaction takes place can be accurately controlled. Control is achieved by providing a support structure (14) for the biomass comprising one or more movable bodies each of which has an internal reticular structure defining a substantial voidage therein and which essent…
