    • In one aspect, the invention encompasses a method of packing and unpacking a column chamber. A mixture of a fluid and a matrix material are introduced through a column chamber inlet so that the matrix material is packed within a column chamber to form a packed column. After the packing, the matrix material is unpacked from the column chamber without moving the column chamber. More specifically, the column chamber having the column chamber inlet or first port for receiving the mixture further has an outlet port and an actuator port. The outlet port is partially closed for capturing the matrix material and permitting the fluid to flow therepast by rotating relative one to the other of a rod placed in the actuator port. Further rotation relative one to the other of the rod and the column chamber opens the outlet and permits the matrix material and the fluid to flow therethrough thereby unpacking the matrix material from the column chamber. In another aspect, the invention encompasses a method of purifying a component of a sample. A column chamber having an inlet end, an outlet end and an actuator end is provided. Flow of matrix material is obstructed by a rod with a binary end inserted in the actuator end. A suspension of the first fluid and the matrix material is flowed into the column chamber to form a packed column of the matrix material within the column chamber. The matrix material is configured to selectively retain a component of the sample. The sample is flowed through the packed column and past the rod to separate the component from the rest of the sample. The rod or the column chamber is rotated with respect to the other to open the outlet end and to remove the matrix material from the column chamber. In yet another aspect, the invention encompasses a system for column-based separations. The system comprises a fluid passageway containing a column chamber and a flow path in fluid communication with the column chamber. The flow path is partially obstructed by a rod. The flow path extends through the column chamber and through the outlet end. The flow path is configured to form a packed column within the column chamber when a suspension of the fluid and the column matrix material is flowed along the flow path.

    • A rearing unit, suitable for piglets, has a heated nest box with openable roof, a pen in communication with the nest box having a perforated floor, a liquid feeding device in the pen having one or more artificial nipples and a solids feed device.The nest box temperature may be thermostatically controlled by a sensor below a perforated floor of the nest box.The unit may be constructed from a slotted framework and boards, the boards being sealed in the slots by an adhesive or inert water-repellant sealant.The unit may house very young piglets up to a weight of from 5 to 8 kg. At that weight, they may then be transferred to a similar unit with a larger nest box until they weigh from 10 to 15 kg.
    • 适合于仔猪的饲养单元具有可开启屋顶的加热巢箱,与具有穿孔地板的巢箱连通的笔,笔中的液体供给装置具有一个或多个人造奶嘴和固体饲料装置。 巢箱温度可以由巢箱的穿孔地板下面的传感器恒温控制。 该单元可以由开槽框架和板构成,板通过粘合剂或惰性防水密封剂密封在槽中。 该单位可容纳5至8公斤重的幼仔。 然后以这种重量将它们转移到具有较大巢箱的类似单元中,直到它们重量为10至15kg。
