A process for making a fibrillated blend of lyocell and cellulose pulp fibers in which a blend of lyocell and cellulose pulp fibers is provided. The lyocell is from 25% to 75% of the total weight of the blend of lyocell and cellulose pulp fibers. The blend is refined in a high shear field device to provide a blend of fibrillated lyocell and pulp fibers having a diameter of 10 to 500 nanometers and a fiber length of 50 to 500 μπι. The high shear field device can be a homogenizer or colloid mill.
A programmed computer or non-transitory computer readable storage media has instructions that are executable by a processor to identify LiDAR data points associated with items of vegetation or other objects. Each LiDAR data point is tested to determine if it lies within the value of a closed surface defined for higher LiDAR points. If so, the LiDAR point is grouped with the LiDAR points associated with a previously identified item of vegetation. If not, a new item of vegetation is identified.
The invention provides methods for multiplying conifer embryogenic tissue. The methods of the invention comprise the steps of: (a) culturing conifer embryogenic tissue in or on a solid multiplication medium comprising one or more growth hormones; and (b) culturing the conifer embryogenic tissue multiplied in step (a) in or on a liquid multiplication medium comprising one or more growth hormones, wherein the initial concentration of growth hormones in the solid multiplication medium of step (a) is greater than the initial concentration of growth hormones in the liquid multiplication medium of step (b).

System and method for detecting features on a laminated veneer lumber billet
The disclosure relates to systems and methods for detecting features on billets of laminated veneer lumber (LVL). In some embodiments, an LVL billet is provided and passed through a scanning assembly. The scanning assembly includes an x-ray generator and an x-ray detector. The x-ray generator generates a beam of x-ray radiation and the x-ray detector measures intensity of the beam of x-ray radiation after is passes through the LVL billet. The measured intensity is then processed to create an image. Images taken according to the disclosure may then be analyzed to detect features on the LVL billet.
The present disclosure is directed generally towards floor panels and flooring drainage systems utilizing two or more interconnected improved floor panels. In some embodiments, the disclosure includes a floor panel having a top surface, a bottom surface, a first longitudinal surface, a second longitudinal surface, a first transverse surface, and a second transverse surface. One or more drainage assemblies are located on either the first transverse surface and/or the second transverse surface. Each of the drainage assemblies include one or more drainage slots and one or more drainage notches. Further aspects are directed towards flooring drainage systems comprising two or more interconnected floor panels according to embodiments of the disclosure.
A computer system for creating artifact-free aerial images of a region of interest. A computer system receives one or more input aerial images that are obtained at different times. A false-color image is created by applying two or more of the input aerial images to different color channel inputs of the false-color image. Based on the color of the pixels in the false-color image, pixels in the two or more input aerial images are classified as representing clear, cloud or shadow areas. An output image is created by combining pixels that are classified as representing clear areas from two or more of the input aerial images.
A method of modulating the development stage of strobili growing on a gymnosperm tree comprises: (a) installing a protective covering over one or more strobili bud(s), wherein the type of protective covering is selected to delay or advance strobili development; and (b) maintaining the protective covering over the strobili bud(s) for a time period sufficient to delay or advance the development stage of the covered strobili buds in comparison to the development stage of naturally growing, uncovered, control strobili.
