In an injection molding machine the injection molding unit and the mold closing unit are at least are at least partially operated by electrical drives in form of a linear motor. The mold unit includes a fixed mold, a movable mold, a plurality of support rods and a plurality of driving cylinders. The magnetic spin storage element is an electron spin-based memory element situated on a silicon based substrate and includes a first ferromagnetic layer with a changeable magnetization state, a second ferromagnetic layer with a non-changeable magnetization state, and a base layer situated between said first ferromagnetic layer and said second ferromagnetic layer. The mass flow rate of permeated fluid as a fraction of the combined mass flow rate of gas and permeated fluid is used to calculate the permeance of the material. The encapsulated cell devices contain cells expressing glutamate transporter proteins.
