Sustainable Preparation of Bio-Based Polybenzoxazine Resins from Amino Acid and Their Application in CO2 Adsorption

A series of new biobased benzoxazine monomers were synthesized by reacting amino acid methyl ester and disphenolic acid methyl ester/eugenol (E) with paraformaldehyde by Mannich condensation reaction. The chemical structures of these biobenzoxazine monomers were characterized by 1H NMR, 13C NMR, mass spectrum, and Fourier transform infrared (FTIR). Their curing behaviors were examined by differential scanning calorimetry (DSC) and FTIR spectroscopy. Thermogravimetric analysis was utilized to evaluate the thermal stability of the polybenzoxazines. The poly(E−lyme) showed highest thermal stability in these obtained biothermosets, Td10% of 373 °C and char yield of 47%, respectively. Furthermore, these polybenzoxazines showed good application in the CO2 adsorption field as the carbon precursor, and the activated carbon materials from poly(E−lyme) had a high surface area of up to 1194 m2 g–1. The remarkably high CO2 adsorption capacity of 5.82 mmol/g was observed on the carbon material ELF0 at 800 mm Hg and 273 K.
Integrated scoring of salinity stress on agro-morphometric and seed storage proteins in barley landraces

Abiotic stress factors, especially high temperatures and salinity, represent the major constraints limiting agricultural production. In present investigation barley forty selected lines was treated in pods at three salt concentrations (25, 50 and 75 mM NaCl) and one control line. In present investigation the maximum salinity affect the yield, spike and total biomass of the plant. For the genetic diversity among barley lines two method were applied morphological evaluation under IPGRI 1994 descriptor and protein profiling, a significant genetic variation index were occur in qualitative traits on the basis of frequency distribution. As result two clusters was obtained at linkage distance 25. Cluster-1 contains 39 lines while cluster-2 contains only 1 line. In protein profiling a total of 12 bands were observed in which 10 bands were polymorphic and two bands 1 and 9 were monomorphic. the genetic diversity on band 1 is 0.65%, band 2 (0.58%), band 3 and 4 (0.45%), band 5 (0.50), band 6 (0.55), band 7 (0.60), band 8 (0.28), band 9 (0.68), band 10 (0.75), band 11 (0.70), band 12 (0.65), these bands were further divided into three zone on the basis of molecular weight. Zone one contain four bands (band 12, 11, 10, 9), zone two contain four (band 8, 7, 6, 5), zone three also contain four bands (band 4, 3, 2, 1). Band 5 dominantly present in zone two bands 10 is dominantly present in zone one which show significant genetic diversity among barley genotypes, a dendrogram tree were also construct for protein bands. As result three clusters were obtained at linkage distance 25. Cluster-1 contains 16 genotypes cluster-2 contains only 14 genotype and cluster-3 contains 10 genotypes out up 40.
User Association in Cloud RANs with Massive MIMO

This paper studies a resource allocation problem where a set of users within a specific region is served by cloud radio access network (C-RAN) structure consisting of a set of base-band units (BBUs) connected to a set of radio remote heads (RRHs) equipped with a large number of antennas via limited capacity front-haul links. User association to each RRH, BBU and front-haul link is essential to achieve high rates for cell-edge users under network limitations. We introduce two types of optimization variables to formulate this resource allocation problem: (i) C-RAN user association factor (UAF) including RRH, BBU and front-haul allocation for each user and (ii) power allocation vector. The formulated optimization problem is non-convex with high computational complexity. An efficient two-level iterative approach is proposed. The higher level consists of two steps where, in each step, one of these two optimization variables is fixed to derive the other. At the lower level, by applying different transformations and convexification techniques, the optimization problem in each step is broken down into a sequence of geometric programming (GP) problems to be solved by the successive convex approximation (SCA). Simulation results reveal the effectiveness of the proposed approach to increase the total throughput of network, specifically for cell-edge users. It outperforms the traditional user association approach, in which, each user is first assigned to the RRH with the largest average value of signal strength, and then, based on this fixed user association, front-haul link association and power allocation are optimized.
Magnesium biodegradable implants coated with polylactic acid

Introduction Magnesium alloys and polylactic acid polymer (PLA) coatings are optimum materials for biodegradable implants [1,2], but their combination is limited because of the low adhesion of PLA on Mg alloys. Plasma electrolytic oxidation (PEO) is a valuable surface modification technique for Mg alloys to promote adhesion of coatings, but limited studies have systematically evaluated this effect. In the present report, dipping method has been used to deposit a PLA coating on AZ31 Mg alloy to tailor its corrosion properties. Furthermore, the surface of the alloy has been modified by PEO [3] to produce a porous coating on AZ31 Mg alloy as an intermediate layer to improve the adhesion strength between PLA layer and the magnesium alloy, and at the same time enhancing the properties of the PLA coating. The influence of dipping parameters (number of layers, withdrawal speed and polymer concentration) in several properties of the coating (mass increment, thickness, roughness, adhesion and resistance polarization) has been evaluated by using the Taguchi design of experiment (DOE) method [4]. In addition, the effect of the PEO treatment has been evaluated for the different coating parameters. Finally, the corrosion behavior of the different systems was also studied.
Application of Image Processing to Health Monitoring for Wire Rope of Lift systems

Rupture of wire ropes is one of severe accidents in lift systems. Before rupture by aging degradation, diameter of wire ropes decreases and surface of wire ropes is rusted. Thus diameters and red rust of wire ropes should be checked in periodic inspections of lift systems in Japan. The diameters are usually measured by using vernier calipers or scales, and red rust is checked with eyes, so there are errors and difference among inspectors. Therefore development of a new monitoring system for the diameters and red rust is required in order to ensure qualities of the inspection and manage the inspection data efficiently. Meanwhile image processing technology has recently been applied to various industries such as automatic driving vehicles. This paper proposes and constructs a health monitoring system for wire rope using image processing. The system consists of a digital camera and a computer. The digital camera takes a photograph of a wire rope and the photograph is analyzed by the computer. The diameter is calculated from the number of pixels of the rope, and red rust is detected by resolving the colour of the photograph into RGB data. This paper describes image processing method for inspection of wire rope and results of verification tests. Photography condition suitable for monitoring was investigated. As a result, the measurement error was less than 1% by adjusting photographing condition.
Programmable compressed sensing using simple deterministic sensing matrices

This paper presents a methodology for programmable on-sensor compressed sensing (CS) of images using pixel binning techniques. This work uses simple sparse deterministic matrices for the ease of implementation. The use of binning technique allows pixels to shift between CS and non-CS modes by the use of control signals. It also allows flexibility to perform CS on selected regions of image. Operation on CS mode has potential to cut raw data rate and power consumption by more than half, double the frame rate and increase low light sensitivity while achieving reconstruction PSNR close to 34 dB. This work also shows that CS has a very good potential for reconstruction of binned images.
Performance-Improved Implementation of the SISO Adaptive Predictive Control Algorithm for Embedded Systems

This article presents a performance improvement over a previously published software-based embedded implementation of the single-input single-output (SISO) adaptive predictive control (APC) algorithm. This article mainly focuses on reducing the execution time of a control iteration of the SISO APC algorithm, while preserving precision. A profiling study of the algorithm is developed, which identifies the performance bottlenecks. Analyzing the outcomes of the profiling study, a set of enhancements for efficient computations of the <italic>Recursion</italic> and <italic>Adaptation</italic> stages of the SISO APC algorithm is proposed, which greatly reduces the computational complexity of the algorithm. The ZYBO development board is the selected platform for testing. Firmware development and optimization is oriented to provide speedup using hardware acceleration, exploiting the processor in the ZYBO at its full extents, targeting the available coprocessors embedded in the core. Comparison with previously published work shows outstanding improvements in execution time, obtaining speedup increments up to <inline-formula><tex-math notation="LaTeX">$\text{12.0}\times$</tex-math></inline-formula>. The enhancements performed to the SISO APC algorithm along with firmware optimization allow the proposed implementation to run at execution times as low as 0.7 <inline-formula><tex-math notation="LaTeX">$\mu$</tex-math></inline-formula>s, which are considerably lower than existing embedded MPC implementations found in the literature.

Abstract Semiliquidambar cathayensis (Hamamelidaceae) is a rare and endangered species endemic to China. Here, we first report and characterize the complete chloroplast genome sequence of S. cathayensis based on Illumina paired-end sequencing data. The complete plastid genome was 160,406 bp in length, which contained two inverted repeats (IRs) of 26,282 bp separated by a large single-copy (LSC) and a small single copy (SSC) of 88,920 bp and 18,922 bp, respectively. The cpDNA contains 132 genes, comprising 86 protein-coding genes, 37 tRNA genes, 8 rRNA genes and one processed pseudogene. The overall GC content of the plastome is 37.9%. The phylogenetic analysis of 20 selected chloroplast genomes demonstrated that S. cathayensis was close to the species Liquidambar formosana.
Droplet Retention Time and Pressure Drop in SiSiC Open-Cell Foams Used as Droplet Separation Devices: A Numerical Approach

Open-cell foams are a promising alternative for the separation of liquid droplets suspended in gas flows at comparably low pressure drops. Separation in such ceramic foams is investigated using the residence time distribution of droplets derived from pore-scale CFD simulations. Silicon-infiltrated silicon carbide (SiSiC) open-cell foam samples (20 and 45 pores per inch, ppi) are considered. The foam structure was reconstructed from microcomputed tomography (μCT) images. To track the droplets, a Lagrangian discrete-phase model was used. The effects of pore size and pore density on the droplet retention time were studied. The flow pressure drop showed remarkable agreement with the in-house experimental measurements. The droplet separation efficiency within the foam structure was found to generally increase with the inlet gas velocity and the droplet inertia.
The E3 ubiquitin ligase TRAF6 is a novel interacting protein of amyotrophic lateral sclerosis-linked misfolded SOD1

Amyotrophic lateral sclerosis (ALS) is a fatal disease, characterized by the selective loss of motor neurons. Mutations in Cu/Zn superoxide dismutase (SOD1) are the second most common cause of familial ALS, and considerable evidence suggests that mutations result in a gain of toxicity due to protein misfolding. We previously demonstrated in the SOD1G93A rat model that misfolded SOD1 exists as distinct conformers and deposits on mitochondrial subpopulations. Here, using SOD1G93A rats coupled with conformation-restricted antibodies for misfolded SOD1 (B8H10 and AMF7-63), we identified the interactomes of the mitochondrial pools of misfolded SOD1. This strategy identified binding partners that uniquely interacted with either AMF7-63- or B8H10-reactive SOD1 conformers as well as a high proportion of interactors common to both conformers. The data have been deposited to the ProteomeXchange Consortium with identifier . Of this latter set, we identified the E3 ubiquitin ligase TNF receptor-associated factor 6 (TRAF6) and determined that exposure of the SOD1 functional loops facilitates this interaction. However, this conformational criterion is not universally fulfilled by all SOD1 mutants and differentiates TRAF6-interacting from TRAF6 non-interacting SOD1 mutants. Functionally, TRAF6 stimulates mutant SOD1 polyubiquitination and aggregation. While TRAF6 E3 ubiquitin ligase activity is required for the former, it is dispensable for the latter, indicating that the polyubiquitination and aggregation of mutant SOD1 mediated by TRAF6 are independent events. We propose that the interaction between misfolded SOD1 and TRAF6 may be relevant to ALS.
Adaptive surface distortions for torque ripple control in vertical-axis wind turbines

Vertical-axis wind turbines have been confined to small-scale generation in urban environments where their omnidirectional capability offers them an advantage over the more ubiquitous horizontal-axis wind turbine. With a drive towards renewable energy, more opportunities exist for the implementation of wind turbines in a multitude of environments. Based on its inherent operational drawbacks, the vertical-axis wind turbine has not undergone extensive investigation. Recently, there has been a resurgence of interest in the technology. This article addresses the torque ripple, a variation in torque produced by the turbine, present during operation. The variation in torque generated by a vertical-axis wind turbine increases the likelihood of failure due to fatigue. Current treatment is symptomatic and addresses the result of the torque fluctuation and not the cause. A novel blade design, capable of altering the lift and drag response through shape alteration, is presented as a solution. The blade design and operation is achieved through genetic algorithm optimization and computational fluid dynamic simulations. Comparisons with previous work show the novel blade presented here surpasses the reduction seen with pitching solutions. A 25% reduction in torque ripple was demonstrated for a 17% reduction in performance coefficient using the surface distortion approach. This surpasses the foil pitching approach which achieved a 15% torque ripple reduction for the same loss in performance coefficient.
Semiresonant Half-Bridge Zeta Converter With Reduced Turn-OFF Currents for High-Efficiency Power Supply

This article presents a semiresonant half-bridge zeta (HBZ) converter for high-efficiency power supply. Since the proposed converter utilizes a primary inductor and secondary capacitor as a resonant tank, it can make a resonant operation during the on-state of a low-side primary switch. Therefore, the proposed converter can effectively reduce turn-off currents of the low-side primary switch and the secondary diode without any additional component and control scheme, which decreases turn-off switching loss and reverse-recovery loss. Moreover, the proposed converter can maintain advantages of the conventional HBZ converter such as high input/output (I/O) voltage gain and wide zero-voltage-switching (ZVS) range with the proposed design procedure. As a result, the proposed converter can improve its efficiency over the entire load conditions compared to the conventional HBZ converter. A 250 W, 300–400 V input, and 56 V output prototype has been built and tested to verify the effectiveness of the proposed converter.
Effect of Brown Algae on Germination, Growth and Biochem - ical Composition of Pepper Leaves ( Capsicum annuum )

In this study, we have evaluated the effects of three brown algae (Cystoseira gibraltarica, Bifurcaria bifurcata and Fucus spiralis) as biostimulant on the germination and the growth of pepper (Capsicum. annuum) in vitro as well as in greenhouse. Two different treatments (Amendment/spray) had been tested accordingly, both with varied concentrations ((0.5%, 1% and 2%) for extract and (C1=0.5 g/pot, C2=1 g/pot and C3= 2.5 g/pot) for amendment). The obtained results have shown that the seeds which were treated by C. gibraltarica, and B. bifurcata with a low concentration (0.5%) were slightly germinated with great length of hypocotyls. Similar results have been obtained for the radicle length. On the other hand, the F. spiralis extract improved the percentage of germination, the length of the radical, the hypocotyls, seedling length and dry weight for the three tested concentrations. Also, all concentrations have a favorable effect on seedling biomass. The growth rate in the greenhouse (the root’s length, the aerial part length, total length and dry weights) was higher for the plants which received higher concentrations of aqueous extracts of the three species B. bifurcata, F. spiralis and C. gibraltarica. Additionally, the maximum quantity of chlorophyll ‘a’ has been recorded in the plants treated with B. bifurcata and C. gibraltarica at 2% and F. spiralis extracts at 0.5%. In regards to the protein content, the maximum values were recorded at the level of the plants that were treated with F. spiralis extract at 0.5%. This study has provided important information about B. bifurcata and F. spiralis species could be considered as a good biostimulant to improve pepper’s growth.
IMPROVING TOLERABILITY OF TAXODIUM DISTICHUM SEEDLINGS TO WATER SALINITY AND IRRIGATION WATER DEFICIENCY I. EFFECT OF SALICYLIC ACID ON WATER STRESS

This study was carried out at the nursery of Horticulture Research Institute, Agriculture Research Center, Giza, Egypt in the two years, 2016 and 2017, aiming to investigate the effect of salicylic acid at different level (0, 0.5, 1.0 and 1.5 g/l) on growth and chemical composition of Taxodium distichum under salinity stress at four concentrations (0, 4, 6 and 8 g/l NaCl). The results revealed that, salinity levels significantly decreased growth parameters, i.e. seedlings height, branches number, root length and shoot, root fresh and dry weight. Also salinity decreased total carbohydrate content and total chlorophyll content in leaves. Salicylic acid application significantly increased growth parameters under salinity stress as compared with salinity treatment without salicylic acid application. Application of 0.5 g/l salicylic acid recorded the best results. Also, combinations that occupied the highest position were: salicylic acid at 0.5 g/l with salinity at 4 and 6 g/l for shoot dry weight and root fresh weight; salicylic acid at 0.5 g/l with salinity at 0 g/l for branch number, root length; salicylic acid at 0.5 g/l with salinity at 4 g/l for plant height 2nd year, root dry weight and total chlorophyll content; salicylic acid at 0.5 g/l with salinity at 6 g/l for plant height in the 1st year and root dry weight; salicylic acid at 1.0 g/l with salinity at 0 g/l for branch number in the 1st and 2nd years and shoot fresh weight; in addition to salicylic acid at 1.0 g/l with salinity at 4 g/l, salicylic acid at 1.5 g/l with salinity at 0 g/l and salicylic acid at 1.5 g/l with salinity at 4 g/l for shoot fresh weight. Combinations that obtained the lowest grade were: salicylic acid at 0 g/l with salinity at 8 g/l for root length, root fresh weight, root dry weight, total carbohydrate content and, total chlorophyll content. It is recommended to in case of irrigation water or soils afflicted with salinity, it is advised to apply salicylic acid at 0.5 - 1.5 g/l as to alleviate salinity stress. So that it could be concluded that the addition of 0.5-1.5g/l of salicylic acid are beneficial to mitigate the adverse effects of salinity stress of T. distichum seedlings.

Operationalizing Operational Logics

Author(s): Osborn, Joseph Carter | Advisor(s): Mateas, Michael | Abstract: Since their initial development by Wardrip-Fruin and further exposition by Wardrip-Fruin and Mateas, operational logics (OLs) have enjoyed broad use and inspired several approaches to game studies. Besides their direct application in describing specific games, OLs underlie several approaches to understanding how games communicate ideas and a variety of projects in player and game modeling and game generation. The key move in all these cases has been to step away from considering games as bags of mechanics and towards viewing them as assemblages of abstract operations from diverse logics.This dissertation expands on the theory of operational logics in its first part, and in the second part applies this refined theory to problems of interest in game modeling, game design support, and automated game design learning.
Twilight migrators: factors determining larval vertical distribution in Nephrops norvegicus with implications for larval retention

The vertical distribution of pelagic marine larvae can greatly influence their dispersal due to depth-varying currents, which can determine larval retention or transport away from critical habitat. Vertical distribution of commercially important lobster Nephrops norvegicus larvae was examined over fishing grounds off the west and east coasts of Ireland. Larval vertical distribution for both grounds was significantly influenced by the temperature differential between the surface and 60 m depth, zooplankton biomass and, to a lesser extent, stratification, measured using the potential energy anomaly. Fixed station sampling was conducted over 3 d in the western Irish Sea (WIS) to investigate the occurrence and extent of a diel vertical migration (DVM). Larvae performed twilight DVM with an ~10 m ascent prior to sunset and sunrise and a descent at midnight and after sunrise. Particle-tracking model simulations were used to examine the effect of DVM behaviour on larval retention over mud habitat. The presence of a DVM actually reduced the likelihood of retention on both the Aran and WIS grounds. Predicted larval retention was unusually low over the Aran grounds in 2018, which is potentially significant in the context of historic stock fluctuations in this area. These findings suggest that understanding larval dynamics could be crucial in managing N. norvegicus stocks on fishing grounds, in particular those with variable interannual oceanography and a low rate of larval donation from other grounds.
