To attach an ear tag (6, 10) to an ear (16) and to remove a sample (22) containing tissue of the ear therefrom, a mandrel (8), which is fastened to a mandrel region (6) of the ear tag, is brought by means of pliers (1) on a first movement path through the ear (16) into a hole (12) formed in a hole part (10) of the ear tag and anchored there, while the sample (22) is taken with the aid of a removal head (17) and is brought out of engagement with the hole (12) by interaction with the mandrel (8) with a movement component oriented transversely to the first movement path, before the mandrel (8) is anchored in said hole.

A quasi-soft catcher, a quasi-soft capture device, and a method for using the same are provided. The quasi-soft catcher includes a base and a plurality of protruding structures for capturing at least one target biological particle from a specimen. The protruding structures are regularly arranged on a board surface of the base. Each of the protruding structures includes an outer portion configured to touch the at least one target biological particle and an inner portion that is connected between the board surface and the outer portion, and a structural strength of the inner portion is less than that of the outer portion. The board surface has an interspace region arranged outside of the protruding portions, and the interspace region occupies 20-80% of the board surface.

A stratum corneum-collecting adhesive composition includes a hydrophobic component having adhesiveness, and a hydrophilic component that is present in a dispersed state in the hydrophobic component.

Described herein are implements that include a vehicle having a system for sensing or testing soil and/or vegetation as the vehicle traverses a field.

The present document relates to a piston corer for acquiring a soil sample. The piston corer comprises a sample reception cylinder for taking in and retaining the soil sample, and which comprises a piston. The piston is moveable over a piston stroke inside the sample reception cylinder. An intake opening at a first end of the sample reception cylinder allows to receive the soil sample upon penetration of the ground, and the piston is configured to move in a direction away from the intake opening during taking in of the soil sample towards an end position of the piston stroke. The piston corer further comprises an activator cooperating with a valve arranged for closing of the intake opening upon activation. The activator is configured for activating a closing action of the valve in response to the piston reaching the end position of the piston stroke. The document further relates to a method of acquiring a soil sample using such a piston corer.

A soil sampler including an elongated barrel having an inner surface defining a piston chamber with open top and bottom ends; a plunger shaped to be slidably received in the chamber and including a piston shaped to frictionally engage the inner surface of the chamber and a plunger cap joined to the piston by a shaft; and at least one longitudinally extending rib projecting inwardly from the inner surface of the chamber and having a bottom surface spaced from the open bottom end to block the piston from moving further towards the open top end, and wherein the plunger cap has at least one notch shaped to receive the at least one rib. A method of assembling a soil sampler includes aligning a notch of a plunger cap of a plunger with a rib in a piston chamber and passing the plunger cap through the chamber.

A grave DNA extractor assembly for extracting DNA without unearthing bodies includes a drill, a grabbing assembly, a viewer, a tunnel tube, and a resealer. The drill is configured to drill through earth and a coffin. The grabbing assembly comprises a handle having a control mechanism. An extension is coupled to the handle and the control mechanism extends through the extension. Each of a plurality of grabber attachments is selectively engageable with the extension. The control mechanism opens and alternatively closes each of the plurality of grabber attachments to grab a DNA sample from within the coffin. The viewer comprises a camera, a light coupled to the camera, and a data cable coupled to the camera. The resealer is configured to patch the coffin.
