    摘要： A hair band apparatus adapted to retain a subject's hair in a desired orientation away, e.g., from the face, and simultaneously impart a part in the subject's hair to enhance desired styling effects, includes a hair band member configured for positioning relative to a head of a subject, and being arranged about a central axis, and a single parting member mounted to the hair band member. The single parting member is configured to impart a part in the subject's hair while mounting the hair band member to the subject's head. The single parting member may be centrally located on the hair band member to provide a central part or be offset to provide a side part.

    摘要： Process for the preparation of polyisoprene with a mainly alternating cis-1,4-alt-3,4 structure comprising polymerizing isoprene in the presence of a catalytic system comprising:
    (a) at least one pyridyl iron complex having general formula (I):




    wherein:
    R1 is selected from linear or branched C1-C20, preferably C1-C15, alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups;
    R2 is selected from linear or branched C1-C10, preferably C1-C3, alkyl groups; X, mutually identical or different, represent a halogen atom such as, for example, chlorine, bromine, iodine; or they are selected from linear or branched C1-C20, preferably C1-C15, alkyl groups, —OCOR3 groups or —OR3 groups wherein R3 is selected from linear or branched C1-C20, preferably C1-C15, alkyl groups.
    n is 2 or 3;
    (b) at least one co-catalyst selected from organo-derivative compounds of aluminum, preferably from
    (b1) aluminoxanes having general formula (II):

    (R4)2—Al—O—[—Al(R5)—O—]m—Al—(R6)2  (II)

    wherein R4, R5 and R6, mutually identical or different, represent a hydrogen atom, or a halogen atom such as, for example, chlorine, bromine, iodine, fluorine; or they are selected from linear or branched C1-C20 alkyl groups, cycloalkyl groups, aryl groups, said groups being optionally substituted with one or more silicon or germanium atoms; and m is an integer ranging from 0 to 1000;
    (b2) aluminum compounds having general formula (III):

    Al(R7)(R8)(R9)  (III)

    wherein R7 is a hydrogen atom, or is selected from linear or branched C1-C20 alkyl groups, cycloalkyl groups, aryl groups, alkylaryl groups, arylalkyl groups, alkoxy groups; R8 and R9, mutually identical or different, are selected from linear or branched C1-C20 alkyl groups, cycloalkyl groups, aryl groups, alkylaryl groups, arylalkyl groups;
    wherein the molar ratio between the aluminum present in the co-catalyst and the iron present in the iron pyridyl complex having general formula (I) is ranging from 5 to 60, preferably from 8 to 55.

    摘要： In the labor claim transaction system in response to a selection of a claim to be sold, a worker node notifies an employer node of a sale application, and records the buyer and the sale amount. When determining that there is no problem with the claim to be sold, the employer node records sale approval information in a distributed ledger, and notifies a buyer node of a sale approval notification. When determining that there is no problem with the claim to be sold, the buyer node records buying approval information in the distributed ledger, and notifies a financial institution node of the sale approval notification. The financial institution mode checks that the sale approval information and the buying approval information are recorded, and records sale amount transfer completion information.
