Bleaching trichomes to remove proteins
A process for bleaching trichome fibers individualized from a trichome source, such as a leaf and/or a stem, is disclosed. The process of bleaching degrades trichome associated protein. Further, the bleaching processes improves the color of the trichomes, exhibiting CIELAB Color values of L* greater than 87 and b* less than 17 and with less than 0.1% protein by weight of molecular weight greater than 3,500 daltons. |

Small diameter, high strength, low elongation, creep resistant, abrasion resistant braided structure
A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc. |

Method for controlling spin-drying cycle of laundry treatment machine
Disclosed is a method for controlling a spin-drying cycle of a laundry treatment machine. The method includes performing a plurality of spin-drying operations by rotating a drum above an adjusted rotational speed range configured to adjust disposition of balls within a ball balancer so as to correspond to a changed amount of eccentricity, and adjusting the disposition of the balls within the ball balancer by rotating the drum within the adjusted rotational speed range, between the respective spin-drying operations. |

Non-planar nonwoven fabrics and methods of making the same
The present invention provides a method of making a nonwoven fabric of continuous fibers that includes forming a nonwoven web on a highly porous woven or knitted forming fabric that defines a pattern of recesses that are bordered by spaced apart filaments extending between the outer surfaces of the fabric and that allows air to pass both downwardly and sidewardly through the forming fabric. Bonded nonwoven webs are formed having protrusions with very low density and high surface area. |

FRP tubular body and method for manufacturing FRP tubular body
A FRP tubular body includes a tubular fiber structure formed by winding a reinforced fiber sheet made of fabric. The reinforced fiber sheet includes first reinforced fiber bundles arranged such that a yarn main axis direction extends in a circumferential direction of the fiber structure and second reinforced fiber bundles arranged such that a yarn main axis direction extends in an axial direction of the fiber structure. The reinforced fiber sheet includes a starting end, a finishing end, and a general portion located between the starting end and the finishing end. The general portion includes the first reinforced fiber bundles and the second reinforced fiber bundles. At least one of the starting end or the finishing end is a decreased portion that is smaller than the general portion in an amount of reinforced fibers per unit length in the circumferential direction of the fiber structure. |

Passive intermittent rotating assembly and electrospinning equipment
A passive intermittent rotating assembly can automatically adjust a part of a cleaning material when the cleaning material cleans a spinning jet each time and that can stably operate in a high-voltage environment. The passive intermittent rotating assembly includes a plurality of first abutment members and second abutment members being arranged respectively at an inner side and outer side of the main wheel along the circumferential direction, and being separated from each other to form gaps for a push portion of a push member to pass through. Each of the first abutment members includes a first inner-side abutment portion and a first outer-side abutment portion provided for abutting against the push portion. Each of the second abutment members includes a second inner-side abutment portion and a second outer-side abutment portion provided for abutting against the push portion. |

Systems and methods for massively parallel combinatorial analysis of single cells
Provided herein are methods that enable parallel evaluation of multiple functional nucleic acids in individual cells or subpopulations of cells, in the context of incubation with other types of single cells. The key insight is concurrent measurement of polynucleic acids derived from small populations of at least two different cell types, such that function in one cell type is linked to the clonal identity of another cell. These methods simultaneously process thousands, millions, or more single cells or small populations of cells. The method integrates molecular, algorithmic, and engineering approaches. This invention has broad and useful application in a number of biological and medical fields, including immunology and drug discovery. |
