Abstract: There is provided a bracket for a biological sample analyser. The bracket comprises abase and an arm extending from the base, the base being engageable with a platform of a biological sample analyser, wherein, when the base is engaged with the platform, the arm extends into a sample plate bay of the biological sample analyser prohibiting access to a portion of the bay. The arm thereby limits misalignment of a sample plate in the bay by blocking access to a portion of the bay only required when the sample plate is loaded into the bay in an incorrect orientation. A biological sample analyser comprising a bay in which a sample plate is loadable in use and the bracket is also provided.

Abstract: An irrigation system for an area receives wide-area meteorological prediction data and sensors deployed within the area collect local-area sensor data. A processor stores received data as historical wide-area meteorological prediction data and data from the sensors as historical local-area sensor data. The processor determines a relationship between the historical wide-area meteorological prediction data and the historical local-area sensor data based on the historical wide-area meteorological prediction data and the historical local-area sensor data, and calculates a prediction on a local-area parameter for a future point in time based on current wide-area meteorological prediction data, and the calculated relationship. The area is then controlled based on the prediction.
