Abstract: Disclosed herein are low density fiber cement articles, such as fiber cement building panels and sheets, comprised of multiple overlaying fiber cement substrate layers having small and uniform entrained air pockets and low density fillers distributed throughout. The combination of entrained air pockets and low density fillers provide a low density fiber cement matrix with physical and mechanical properties similar to comparable low density fiber cement matrix without entrained air pockets.

Abstract: Disclosed herein are low density fiber cement articles, such as fiber cement building panels and sheets, comprised of multiple overlaying fiber cement substrate layers having small and uniform entrained air pockets distributed throughout. Also disclosed herein are air entrainment systems and methods for manufacturing aerated low density fiber cement panels or sheets with consistent air void content and uniform air void distribution. Also disclosed herein are air entrainment technologies adapted to work in conjunction with the Hatschek process to produce aerated fiber cement articles having controlled air void content and distribution.

Abstract: A GRASE-type PROPELLER sequence called Steer-PROP is disclosed. This sequence exploits a serious of steer blips together with rewinding gradient pulse to traverse k-space. Steer-PROP improves the scan time by a factor of 3 or higher compared to FSE-PROPELLER, provides improved robustness to off-resonance effects compared to EPI-PROPELLER, and addresses a long-standing phase correction problem inherent to GRASE based sequences. Steer-PROP also enables intra-blade, inter-blade, and inter-shot phase errors to be separately determined and independently corrected.

Abstract: In PROPELLER utilizing EPI k-space sampling, phase errors arising primarily from eddy currents can considerably degrade image quality. The phase errors include spatially constant phase errors, spatially linear phase errors, and oblique phase errors. Methods to measure and correct for these phase errors are disclosed. Two or three reference scans are acquired, each reference scan being mutually orthogonal along the orthogonal physical gradient axes in a MRI system. A spatially constant phase error and a spatially linear phase error are determined from each of the reference scans for each relevant physical gradient axis. These phase errors can be used to predict the constant, linear, and oblique phase errors in each blade of an EPI PROPELLER k-space data set. With the known phase errors for each blade, constant, linear, and/or oblique phase correction is applied prior to or during PROPELLER image reconstruction, producing an image with substantially reduced artifacts.

Abstract: Representative methods and systems are disclosed for reducing image distortion or increasing spatial resolution in echo planar magnetic resonance imaging. In representative embodiments, a targeted field of view (FOV) image is divided into segments, with each segment having a predetermined overlap region with an adjacent segment, such as in a phase-encoding direction. Image data is acquired for each segment, sequentially or simultaneously, using a reduced phase-encoding FOV with a 2D radiofrequency (RF) excitation pulse, and rotated and scaled magnetic field gradients. The 2D RF excitation pulse may also be modulated, such as onto a plurality of different carrier frequencies, for simultaneous acquisition of multiple segments in the same imaging plane. Using the spatial response of the 2D RF excitation pulse, the acquired image data for each segment of the plurality of segments is combined to generate a combined magnetic resonance image having the targeted field of view.

Abstract: Disclosed are cold flow resistant and dimensionally stable compositions containing a diene rubber and a conjugated diene monovinylarene block copolymer, and generally, these compositions have solutions viscosities and cold flows that are less than that of the diene rubber. Methods for reducing cold flow and for storage-stabilizing bales of diene rubbers also are disclosed.

Abstract: The present invention provides an anthropogenic glucagon-like peptide-1 (GLP-1) recombinant protein molecule fused with an anthropogenic immunoglobulin subtype (IgG2) Fc section and a preparation method and purpose thereof. The fusion protein has the biological activity of GLP-1, and also has a significantly prolonged half-life in vivo. The fusion protein can be used to treat type II diabetes, obesity, and other diseases that are treated by decreasing serum glucose, suppressing gastrointestinal motility, and emptying or suppressing food intake.

Abstract: Described herein is combination of flocculants for flocculating fines solids in a suspension thereof. The combination includes: (a) an anionic polymer flocculant, and (b) a charged particle-polymer hybrid flocculant that includes charged core particles having an average size between about 150 nm and about 800 nm and each having a polymer polymerized thereon. The anionic polymer flocculant is to be added before, or at substantially the same time as, the charged particle-polymer hybrid flocculant.
