Abstract: A plastic mulch retriever comprises a body and at least one set of cutting or digging elements mounted to the body to loosen plastic mulch embedded in the ground. At least one conveyor is mounted to the body rearward of the at least one set of cutting or digging elements. The conveyor engages the loosened plastic mulch and removes at least some of the ground material attached to the extracted plastic mulch. At least one storage device can be mounted to the body rearward of the conveyor to store the retrieved plastic mulch. Embodiments of the plastic mulch retriever comprise multiple sets of cutting or digging elements and multiple respective conveyors.

Abstract: A method of detecting and/or analyzing a radioactive source emitting charged or neutral particles in a biological tissue, consisting essentially in using scintillating fibers having particular ratios of length or diameter to range of the particles emitted by the source; scanning the surface of the material with the detection rod; collecting by means of a SiPM, the scintillation light output generated by the particles having interacted with the scintillating fibers and emitted at the outlet end; optionally selecting signals corresponding to the particles entering the scintillating fibers in a substantially axial direction, that eliminates the particles from certain angles between the axis of the scintillating fiber and the direction of the particles entering the scintillating fiber, correlating the scintillation light output and the selected signals to the presence of a source of radiation located in the material to be analyzed; and optionally communicating these data to the user.

Abstract: The invention concerns lake compositions based on natural macromolecules (gelatin, chitosan, pectine etc.) with possible additions of vinyl polymers, metal-alcoxides etc., characterized by a barrier effect modulated in situ, in particular as a function of the relative humidity in the exterior ambient.

Abstract: Plastic mulch retrievers are disclosed comprising a body and at least one set of cutting or digging elements mounted to the body to loosen plastic mulch embedded in the ground. At least one conveyor is mounted to the body rearward of the at least one set of cutting or digging elements.

Abstract: The invention relates to detection of radiations by means of any appropriate devices, particularly those comprising small probes used e.g. in diagnostics or in surgery, or in biomedical or pharmacological research. The aim of the invention is to improve the performance of probes and their working methods in terms i.a of background, miniaturization sensitivity and selectivity.
