The present invention provides a kidney production method including a step of tissue-specifically removing a metanephric mesenchyme of a metanephros of a non-human animal; a step of transplanting a human kidney precursor cell into the metanephros; and a step of advancing development of the metanephros, which is a step in which the transplanted human kidney precursor cell is differentiated and matured to form a part of the kidney.

Kidney production method

The present invention provides a kidney production method including a step of tissue-specifically removing a metanephric mesenchyme of a metanephros of a non-human animal; a step of transplanting, into the metanephros, a kidney precursor cell derived from a non-human animal which is allogeneic or xenogeneic to the non-human animal; and a step of advancing development of the metanephros, which is a step in which the transplanted kidney precursor cell is differentiated and matured to form a part of the kidney.

A main controller controlling an operation of a work vehicle includes a determination unit and an abnormal condition determination unit. The determination unit determines whether or not an attachment has a sensor based on information on an attachment. When the determination unit determines that the attachment has the sensor and when the abnormal condition determination unit cannot receive a signal from the sensor, the abnormal condition determination unit determines that an abnormal condition has occurred.

Work vehicle and method of controlling work vehicle

A work vehicle includes an operation apparatus for operating a work implement, a valve adjusting a flow rate of a hydraulic oil operating the work implement, an electromagnetic proportional control valve provided in a pilot oil path connecting a pilot oil pressure source and a pilot chamber of the valve to each other and generating a command pilot pressure with a source pressure input from the pilot oil pressure source being used as a primary pressure, and a main controller outputting a command current operating the electromagnetic proportional control valve in accordance with an operation of the operation apparatus. The main controller includes a data table storage unit storing data for predicting an operation speed of the work implement and a calibration unit calibrating data on the condition that an operation onto the operation apparatus is performed.

An organ for transplantation having a kidney, a ureter, and a urinary bladder and an organ structure in which a first ureter, a first urinary bladder, a second ureter and a second urinary bladder are sequentially connected to a kidney can produce urine and excrete the produced urine, and thus is useful for transplantation.

Organ for transplantation and organ structure

A work implement has a boom, an arm, and a bucket pivotable around a bucket axis which is a pivot axis with respect to the arm and a tilt axis orthogonal to the bucket axis. The hydraulic cylinder has the bucket pivot around the tilt axis. The regulation valve regulates an amount of supply of a hydraulic oil to be supplied to the hydraulic cylinder based on a command signal. The position sensor measures a stroke length of the hydraulic cylinder. The control unit resets the stroke length measured by the position sensor. The control unit determines proximity to a stroke end of the hydraulic cylinder, generates a command signal for increasing a degree of opening of the regulation valve in the proximity of the stroke end, and resets the stroke length measured by the position sensor while the regulation valve is open in response to the command signal.

A work machine control system that controls a work machine including a working device having a working tool that rotates about a shaft line includes: a target construction shape generation unit that generates a target construction shape indicating a target shape of a construction target of the work machine; a target shape calculation unit that calculates a control target shape which is a target shape when controlling rotation of the working tool from the target construction shape and calculates an extended target shape obtained by extending the control target shape; and a working device control unit that controls the rotation of the working tool about the shaft line based on a distance between the working tool and the control target shape and the extended target shape.

Work machine control system, work machine, and work machine control method

A control system for a work vehicle having a work implement includes a first operating lever for the work implement, a first operating member and a controller. The first operating member is provided on the first operating lever. The controller is configured to perform an automatic control of the work implement. The controller is configured to perform a function of the automatic control, which is allocated to the first operating member, in response to operating the first operating member when a performance condition, including that the first operating lever is located in a neutral position thereof, is satisfied.

Control system for work vehicle, control method and work vehicle

A construction machine control system includes: a target construction ground shape generation unit which generates a target construction ground shape indicating a target shape of an excavation target; a working device control instruction determination unit which outputs an instruction for driving the working device in a working device operation plane orthogonal to at least one of a boom axis, an arm axis, and a bucket axis based on an operation state of at least one of an arm and a bucket and a distance between the bucket and the target construction ground shape; and a tilting control instruction determination unit which outputs an instruction for performing a tilting control of the bucket about a tilting axis based on a tilting state of the bucket and the distance between the bucket and the target construction ground shape.

Construction machine control system, construction machine, and construction machine control method

The present invention provides an artificial kidney precursor containing a non-human mammalian metanephros separated out from a living body, wherein the metanephros has been subjected to freezing and thawing treatments outside a living body, and contains mammalian mesenchymal stem cells transferred outside a living body, and a method of production thereof.
