Abstract: A terminal apparatus includes: a reception unit which receives, from a base station apparatus, a physical downlink control channel including downlink control information in a search space specific to the terminal apparatus; and a control unit which determines the number of bits of a time domain resource allocation field in the downlink control information. The time domain resource allocation field is a time domain resource allocation field for a physical downlink shared channel. A default table indicates a time domain resource allocation configuration for the physical downlink shared channel. When a parameter is not received, the number of bits of the time domain resource allocation field is determined based on the number of the in the default table.

Abstract: A fibrous-mass product is provided which has both water retentivity and strength, and in addition, good air permeability, and can be used as an artificial soil particle. A fibrous-mass product includes a core portion which is an aggregate of fibers, and a water permeable membrane which covers the core portion. The water permeable membrane has porous structure, and covers at least 40% of an outer surface portion of the core portion. The core portion has a water retention material. Ion exchange capability is imparted to at least one of the core portion and the water permeable membrane. The fibrous-mass product has a grain size of 1-10 mm. The amount of moisture retained in the fibrous-mass product is adjustable between a wet state in which the core portion is saturated with moisture and an air permeable state in which the core portion is not saturated with moisture.

Abstract: A high-quality and easy-to-handle artificial soil particle is provided which can exhibit well-balanced basic soil functions. In the artificial soil particle 10, a plurality of fillers 1 having a small hole 2 ranging from the subnanometer to the submicrometer scale are clustered together. A communication hole 3 ranging from the submicrometer to the submillimeter scale is formed between the fillers 1. The small holes 2 are distributed and arranged around the communication hole 3 so that the communication hole 3 is allowed to take in water W and nutrients K, N, and P from the outside and the small holes 2 are allowed to receive the nutrients K, N, and P from the communication hole 3. The fillers 1 are joined together into a three-dimensional network so that the total volume of the communication holes 3 is greater than the total volume of the small holes 2.

Abstract: A purpose of the present invention is to provide a plant cultivation method with which the growth of plants can be promoted by adjusting the environment within a culture medium, and to provide a plant cultivation container with which this cultivation method can be easily and effectively performed. The present invention provides a plant cultivation method for plants which are raised in a culture medium, which cultivation method is characterized in that water is only supplied to the plants from the side of the culture medium, and provides a plant cultivation container and a plant cultivation device used therefor.
