The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and / or detection of particles, such as cells and / or beads. The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and / or analysis of particles, such as cells, viruses, organelles, beads, and / or vesicles. The invention also provides microfluidic mechanisms for carrying out these manipulations and analyses. These mechanisms may enable controlled input, movement / positioning, retention / localization, treatment, measurement, release, and / or output of particles. Furthermore, these mechanisms may be combined in any suitable order and / or employed for any suitable number of times within a system. Accordingly, these combinations may allow particles to be sorted, cultured, mixed, treated, and / or assayed, among others, as single particles, mixed groups of particles, arrays of particles, heterogeneous particle sets, and / or homogeneous particle sets, among others, in series and / or in parallel. In addition, these combinations may enable microfluidic systems to be reused. Furthermore, these combinations may allow the response of particles to treatment to be measured on a shorter time scale than was previously possible. Therefore, systems of the invention may allow a broad range of cell and particle assays, such as drug screens, cell characterizations, research studies, and / or clinical analyses, among others, to be scaled down to microfluidic size. Such scaled-down assays may use less sample and reagent, may be less labor intensive, and / or may be more informative than comparable macrofluidic assays.

The method comprises the following steps: dividing the blue crabs into three classes, and choosing the blue crabs in the first and secondclasses as the cultivated objects of the soft-shell crabs; putting a single blue crab in the first class in a crab pot, stacking and binding 3 to 5 crab pots together to be a group of crab pots, and then putting the groups of crab pots into a cultivating pool for intensive cultivation; during the cultivation period, transferring the whole group of crab pots to a black barrel or a small pond in which a natural shell-removing agent is added to soak every day; putting the crab pots into calcium hydroxide solution to soak and disinfect and promote calcium absorption and shell removal, and then putting the blue crabs subjected to socking into the original cultivating pool again; timely selecting out the blue crabs which just remove shells and transferring, then carrying out low-temperature paralysis fresh preservation or cryopreservation on the selected blue crabs; carrying out mixed group cultivation on the blue crabs in the second class in a cultivating pool, after the state of the blue crab in the second class in the shell removing cycle enters the state of the blue crab in the first class, selecting out and transferring the blue crabs to the crab pots, then cultivating the blue crabs to be the soft-shell crabs.

Cluster setting rate improving method by mixed cropping of different corn varieties
ActiveCN109197435AIncrease the amount of effective pollenExtend the duration of loose powderCereal cultivationHigh resistancePollen
The invention discloses a cluster setting rate improving method by mixed cropping of different corn varieties. Varieties with high resistance in the adverse condition are mixed cropped reasonably to prolong pollen dispersal duration of a mixed cropped group, provide sufficient high-quality pollen for insemination and setting of gynoecium, improve the group setting rate, and solve the problems thatadverse growth of male and female ears in the adverse condition causes unsatisfied encountering state of florescence, relatively low pollen quality and less pollen. Fertility and habit change of thevarieties in meteorological disasters are used ingeniously to match and combine the variables properly, a reasonable mixed cropping plantation belt is formed, the cluster setting rate of the mixed group is improved, and the group output is improved. The pollen complementary effect can be used to overcome the problem that gynoecium in the variety with early fusule but late pollen dispersal in the adverse condition needs to wait for pollen, there is pollen when filaments are provided to realize insemination, and insemination is completed when the filaments are most vital.

Mouse-specific anti-fertility polypeptide
InactiveCN102827285APeptide/protein ingredientsMacromolecular non-active ingredientsMixed groupFertility
The invention discloses six immune anti-fertility polypeptide segments, all of which have excellent immunogenicity. The six immune anti-fertility polypeptide segments can stimulate the organisms to generate specific antibodies and induce the anti-fertility function. According to the fertility comparison of antigen polypeptide immunized mice and the immunized mice in a control group (KLH (keyhole limpet homocyanin) control group), immunization by the six polypeptide antigens mixed group can significantly reduce the farrowing rate of the male and the female mice, wherein litter sizes in the male and the female mice is respectively reduced by 62.8% and 50%. The athletic ability and activity of sperms are significantly reduced in the HE6 polypeptide group or the mixed group immunized male mice. The polypeptide with high-efficiency anti-fertility effect establishes the foundation for research of the mouse-specific immune anti-fertility vaccines, and can be used for application of various anti-fertility preparations.

Fractional slot winding configuration for electric motor
InactiveCN101958586AMagnetic circuit stationary partsManufacturing dynamo-electric machinesElectrical conductorMixed group
The invention relates to fractional slot winding configuration for electric motors. Methods and apparatus are provided for stator assembly for use with an electric motor assembly. The stator assembly includes, but is not limited to a stator core that has an inner surface and a plurality of stator slots defined in the inner surface. A fractional slot winding having a plurality of conductors is coupled to the stator core. Each stator slot contains a group of the conductors arranged in a radially adjacent configuration. The groups of conductors in each of the stator slots together form a plurality of concentric rings of conductors. The conductors in each mixed group are arranged such that conductors carrying differing phases of electric current are arranged in a radially alternating configuration.

Method for preparing medical dressing
The invention discloses a preparation method of a medical dressing used for treating burns and scalds after operation. Combining 60-70% (w / w) of carboxyvinyl polymer and 40%-30% (w / w) of lauryl polyoxyethylene ether into a polymer compound is group A, and take 40-50ml of propylene glycol and 40-50g of glycerin , 60-70g of liquid paraffin and 1000ml of purified water are mixed under high-shear stirring to make a mixed liquid group B, take 20-30g of emulsified silicone oil and 10-20g of water-soluble laurozone to make a mixed group C, take 20-30g of tea tree oil and water-soluble tea tree dew 300-500g to make solution group D after stirring and strengthening, then place group A in a slow-stirring reaction kettle and add group B, group C and group D respectively to form a gel-like sol. Soak the sol into medium-density polyurethane sponge or degreasing gauze, wool felt, various medical non-woven fabrics and seal the package. It can promote skin metabolism, antibacterial, sterilizing, moisten the wound, relieve pain, no sticky feeling, accelerate wound healing, and minimize external skin damage.
