A release device for fishing cable may have a first tube unit defining an inner cavity, the first tube unit configured to be connected to a fishing cable, a piston unit in the inner cavity of the first tube unit to separate the inner cavity in a first chamber and a second chamber, with a fluid passage between the first chamber and the second chamber to allow fluid flow at least from the first chamber to the second chamber. A biasing member may bias the piston unit to a resting position. A piston rod unit is connected to the piston unit for moving therewith, the piston rod unit projecting out of the first tube unit. A second tube unit connected to the piston rod unit so as to move therewith. A detachable connector is operatively connected to the piston rod unit and/or the second tube unit, the detachable connector detaching from a remainder of the release device when the piston unit reaches a release position. The release device is configured to reach the release position for a load L2 of a duration T2, and to keep the detachable connector operatively connected to the piston rod unit and/or second tube unit for a load L1 of a duration T1, wherein L1>L2 and T1
A process for preparing a sample that is substantially enriched of a marine-derived protein. The process comprises extracting and fractioning a physiological material obtained from a marine species. The marine-derived protein may be snow crab hemocyanin. It is used in pharmaceutical and bio-pharmaceutical applications.

A snowplough system of the type being releasably anchored to a front end of a vehicle comprises a plough blade. A vehicle interface is adapted to be releasably anchored to the vehicle. A snowplough interface is operatively connected to the vehicle interface and comprises a structure supporting the plough blade, the structure being movable to displace the plough blade between a ploughing position and a retracted position. A wheel unit is connected to at least one of the vehicle interface and the snowplough interface, and comprises at least one wheel located in front of a front axle of the vehicle, to support part of the weight of the plough blade when in the retracted position.

N,N,N-trialkylaminopolymers, methods of their preparation and uses thereof
There is provided a method for the preparation of an N,N,N-trialkylaminopolymer having one or more unsubstituted heteroatoms different from nitrogen atom. The method comprises a first step of alkylating an aminopolymer to produce an N,N-dialkylaminopolymer, wherein substantially no N,N,N-trialkylaminopolymer is produced; and a second step of alkylating the N,N-diaminopolymer to produce the N,N,N-trialkylaminopolymer. The N,N,N-trialkylaminopolymer is produced with a satisfactory degree of quaternization and with only a low percentage of the unsubstituted heteroatoms alkylated. The N,N,N-trialkylaminopolymer can be an N,N,N-trialkylaminopolysaccharide or an N,N,N-trialkylchitosan such as N,N,N-trimethylchitosan.

There is provided a culture bag for use in a photobioreactor. The bag can comprise at least one wall having at least one inlet disposed at a first end portion of the at least one wall or adjacently thereto. The at least one wall defines an internal chamber for receiving a culture medium. The bag also comprises at least one injector for injecting a gas inside the bag, the at least one injector being disposed at a second end portion of the at least one wall or adjacently thereto. The bag also comprises at least one outlet for harvesting a content of the bag, the at least one outlet being disposed at the second end portion of the at least one wall or adjacently thereto. The bag can be translucent or transparent and be effective for holding and sealingly maintaining the culture medium inside the bag and inside the photobioreactor. There is also provided a photobioreactor and a photobioreator modular system.
