    Abstract: A process and material therefrom is described where a material comprised of a continuous orientable polymer matrix with one or more discontinuous or continuous second phases is stretched in the solid state using more than one device to apply force to the unoriented material to form a material that consists of a continuous oriented polymer matrix with one or more other phases. At least one of the phases releases from the oriented polymer matrix forming voids during the orientation process, thereby reducing the density to less than that of the original unoriented mixture. One or more of the phases may stay bonded to the continuous oriented polymer phase, acting as a reinforcing agent and forming no voids. Methods for forming such a material allowing for the control of the final shape and affecting the final density independent of the composition are also disclosed.

    Abstract: Meltblown lyocell fibers incorporating polyolefinic hydrophobic polymers are disclosed. The polymer is distributed fairly uniformly within the fiber and exists as approximately one to two micron diameter domains. The fibers have a high hemicellulose level, show reduced water retention values and have varying diameters depending on processing conditions. The fibers have a brightness of at least 60.

    Abstract: Meltblown lyocell fibers are disclosed which show a high degree of antimicrobial activity against E, coli and C. albicans. The fibers are prepared by adding inorganic and organic compounds to the NMNO dope prior to spinning. The additives are uniformly distributed throughout the fiber cross section and longitudinal sections show relatively smooth or grainy, rough surfaces depending on the additive used.

    Abstract: Aspects of the present invention are directed at using LiDAR data to identify attributes of vegetation. In this regard, a method is provided that identifies the location of individual items of vegetation from raw LiDAR data. In one embodiment, the method includes selecting a coordinate position represented in the LiDAR data that generated a return signal. Then, a determination is made regarding whether the selected coordinate position is inside a geographic area allocated to a previously identified item of vegetation. If the selected coordinate position is not within a geographic area allocated to a previously identified item of vegetation, the method determines that the selected coordinate position is associated with a new item of vegetation. Li this instance, a digital representation of the new item of vegetation is generated.
