The polypeptide is useful in improving sperm-egg binding by fresh sperm, restoring sperm-egg binding following a cryopreservation cycle, enhancing fertilizing potential, and producing antibodies to determine fertilizing potential of sperm, determining sperm-binding sites on egg investments, and contraception.

A grease removal system includes a solid interceptor fluidly coupled to a grease trap tank, which is fluidly coupled to a secondary tank. The secondary tank contains an enzyme solution which biodegrades the grease. The grease removal system may also include a solid interceptor fluidly coupled to a grease trap tank which is fluidly coupled to a replaceable container. Grease is diverted from the grease trap tank into the replaceable container and thereafter discarded. The grease removal system may include a grease trap tank utilizing a unique arrangement of grease baffles and solids baffles which work together to isolate grease within a single region of the grease trap tank for ease of disposal. Finally, the grease removal system includes two level sensors which detect the level of grease within the grease trap tank and, at the appropriate level direct the accumulated grease from the grease trap tank.
摘要:
A new and distinct rootstock variety of Prunus named ‘VVA-1’ that is characterized by a dwarf habit, resistance to low temperatures, the ability to serve well as rootstock that is compatible with other crops, and the ability to propagate well. In combination these traits set the new cultivar apart from all other existing varieties of Prunus rootstock.
摘要:
The present invention relates to a process for obtaining fatty acid esters from triglycerides by means of alcoholysis. In particular, the invention relates to a process for the transesterification of fat and/or oil by alcoholysis wherein, in order to accelerate the process in the initial stage, at least one alkanol fatty acid ester is added in a quantity such that the reaction mixture produced thereby consists of one phase. A high reaction rate can thereby be maintained in the process from the beginning.

A foldable child support device includes a main frame unit, first and second frame units, and a seat support member. The main frame unit includes left and right frame portions. The first frame unit includes a first rod member, two arm members connected respectively to the left and right frame portions, and a first connector unit for connecting pivotally the first rod member to the arm members such that the first frame unit is foldable. The second frame unit includes a second rod member, a third rod member connected pivotally to the main frame unit, and a second connector unit for interconnecting pivotally the second rod member and the third rod member such that the second frame unit is foldable. The seat support member is mounted on the main frame unit, and cooperates with the first frame unit to define a seating area.
摘要:
The present invention includes an adjustable lighting fixture having a housing and light holders which are able to extend, pivot, spin, and slide with respect to the housing, a mounting arm, or each other. The lighting fixture may thus provide enhanced lighting during events, such as live performances, teleconferencing, filming, or videotaping. Each adjustable lighting fixture generally includes a light holder positioned on a mounting arm pivotally or otherwise movably connected to the housing. The lighting fixture uses fluorescent light sources. When enhanced lighting is not required, the light holders may be restored in the housing in an aesthetic manner.

摘要:
A small swivel type working vehicle includes a running device (4), a swivel base (2) mounted on the running device (4) to be swivelable about a vertical swivel axis (X), a driver's seat (5) mounted on the swivel base (2), a control box (6) mounted upright on a top surface of the swivel base (2) forwardly of the driver's seat (5), a swing bracket (18) supported to be swingable about a vertical pivotal axis (19a) by a flange unit (17) provided at a front end of the swivel base (2), a boom (20) attached to the swing bracket to be swingable about a horizontal shaft (22), and a boom cylinder (21) connected at one end thereof to the swing bracket (18) and at the other end to the boom (20) for swinging the boom (20). The boom cylinder (21) is disposed outside the boom (20) to extend along a rear surface thereof. A walk-through space (100) is defined between the control box (6) and the driver's seat (5). A distance (L1) from the swivel axis (X) of the swivel base (2) to the vertical pivotal axis (19a) is substantially the same as a distance (L2) from the swivel axis (X) to a rear end of the swivel base(2).
