Abstract: The invention relates to a process for forming a pre-defined recess in a cured or cast explosive composition comprising the steps of: i) providing a female mould, ii) providing a male former, and locating said male former proximate to the female mould to create a gap between said male former and female mould, iii) forming an admixture of a curable/castable explosive composition, charging the gap with the admixture of explosive composition, causing the cure or cast of said curable/castable explosive composition, removing the male former to furnish a cured or cast explosive composition with a pre-defined recess.

Abstract: A comb to collect and subsequently crush parasite having a body having a handleable portion, a row of closely spaced teeth projecting outwardly from the body, and a crusher engaged to one of the teeth or handle. The teeth are configured to collect the parasites when combed through hair, and the teeth present upper surfaces that form a planar first face. The crusher has at least one planar crushing surface configured to move to abut against the first face of the teeth to cause the parasites to be crushed between the at least one crushing surface and the first face of the teeth.

Abstract: The present invention provides a synthetic antiferromagnetic (SAF) nanoparticle. The SAF nanoparticle includes at least two ferromagnetic layers and at least one non-magnetic spacer layer. The spacer layer is situated in between planar surfaces of the ferromagnetic layers. The saturation field of the SAF nanoparticle is tunable by the geometry and composition of the nanoparticle. Preferably, the saturation field can be tuned to be between about 100 Oe and about 10,000 Oe. Also preferably, the SAF nanoparticle has a magnetic moment of at least 800 emu/cm3. In a preferred embodiment, the SAF nanoparticle has at least one of a biomolecule, a recognition moiety, or a molecular coating attached to its surface. The SAF nanoparticle may also have a dye attached to its surface.

Abstract: In a spin valve, at least one AP pinned sublayer and/or one AP free sublayer comprise high resistivity alloys of the type AB, wherein A is selected from the group consisting of CoFe, NiFe, and CoFeNi, and B is selected from the group consisting of B, Ta, Nb, Zr, and/or Hf. The resistivity value of the highly resistive layer is typically between about 30 &mgr;&OHgr;-cm and 100 &mgr;&OHgr;-cm. The highly resistive layers reduce the shunting of the sense current away from the rest of the structure, and prevent electrons from being shunted away from the active region of the spin valve and, thus, reducing &Dgr;R/R. The spin valve of this layered structure can increase the overall sheet resistance and optimize the &Dgr;R/R value of the spin valve.

Abstract: An SV sensor with the preferred structure Substrate/Seed/Free/Spacer/Pinned/AFM/Cap where the seed layer is a non-magnetic Ni—Fe—Cr or Ni—Cr film and the AFM layer is preferably Ni—Mn. The non-magnetic Ni—Fe—Cr seed layer results in improved grain structure in the deposited layers enhancing the GMR coefficients and the thermal stability of the SV sensors. The improved thermal stability enables use of Ni—Mn with its high blocking temperature and strong pinning field as the AFM layer material without SV sensor performance degradation from the high temperature anneal step needed to develop the desired exchange coupling.

Abstract: Magnetic particles are prepared and used for selective separation of affinity bound partners in solution. The magnetic particles have large magnetic moments which can be made such that different strengths of magnetic moments and/or different magnetic field dependencies can be used to allow for separation of several affinity partners simultaneously. Magnetic particles having different magnetic moments and different attached acceptor molecules move at different rates in a magnetic field. The magnetic particles have a first ferromagnetic layer having a moment oriented in a first direction, a second ferromagnetic layer having a moment oriented in a second direction generally antiparallel to the first direction and a nonmagnetic spacer layer located between and in contact with the first and second ferromagnetic layers.
