    Abstract: This study examines the effects of two types of online remedial reading interventions on the reading strategy and comprehension, motivational beliefs, and self-efficacy of 36 low-achieving students (explicit teaching before reciprocal teaching [ET-RT] vs. direct instruction [DI] ). We designed a 10-unit online remedial English reading program based on the theoretical framework of the ET-RT model developed by Palincsar and associates. The study investigates the patterns of teacher modeling in both groups and interactive dialogue in the ET-RT group. Students' experiences and perceptions of reading interventions are also explored. The study reveals that implementing ET-RT significantly improved student reading comprehension and strategies and self-efficacy compared with DI. Triangulation with a survey indicated that ET-RT instruction reduced learners' anxiety about learning English and increased interest in reading. Moreover, the ET-RT learners had a better command of reading strategies than the DI learners. However, the qualitative evaluation of learner performance revealed that both groups showed moderate satisfaction and that most students accepted the interventions. ET-RT learner excerpts highlight the importance and usefulness of explicit reading strategy instruction. These findings indicate that both ET-RT and DI instruction have value. However, the finding that ET-RT outperformed DI suggests the need to reconsider the design and implementation of remedial English reading instruction.

    Abstract: The potential of surface covalently bonded rhBMP-2 biodegradable chitosan membrane was examined for guided tissue regeneration (GTR) applications. A chitosan surface-bonded rhBMP-2 membrane was produced via amide bond formation between chitosan and rhBMP-2 using EDC/NHS as the catalyst. The chitosan surface-bonded rhBMP-2 membrane retained more than 70% of the initial rhBMP-2 after 4 weeks of incubation, whereas the chitosan surface-adsorbed rhBMP-2 membrane retained only 30%. The surface-bonded rhBMP-2 did not denature, but expressed sustained biological activity, such as osteoblast cell adhesion, proliferation, and differentiation. X-ray images and histology of an in vivo segmental bone defect rabbit model showed that the chitosan surface-bonded rhBMP-2 membrane induced new bone formation. The chitosan surface-bonded rhBMP-2 membrane has the potential as a bioactive material for GTR.

    In: Journal of Bioactive and Compatible Polymers, SAGE Publications, Vol. 26, No. 5 ( 2011-09), p. 519-536
    Abstract: Two different dicarboxylic acids (glutamic acid and succinic acid), instead of acetic acid, were used simultaneously as solubilizing and crosslinking agents in the preparation of chitosan-based hydrogel. Sustained, homogeneous and transparent hydrogels were formed with amide linkage formations. X-ray diffraction and Fourier transformed infrared (FTIR) were used to examine the crystal structure and chemical composition of chitosan/glutamic acid (C/G) hydrogel and chitosan/ succinic acid (C/S) hydrogel, respectively. The in vitro cell cultures confirmed that the amine group was effective in promoting cell affinity. Histological examinations revealed that reepithelialization and regeneration of tissue was achieved 50% faster by dressing the wound with the C/G hydrogels. This chitosan/dicarboxylic acid hydrogel system has potential as wound dressing material.

    In: Journal of Bioactive and Compatible Polymers, SAGE Publications, Vol. 26, No. 2 ( 2011-03), p. 191-206
    Abstract: In this study, the in vivo soft tissue response of chitosan/γ-poly(glutamic acid) (γ-PGA) polyelectrolyte complex (PEC) using a rat model was assessed using chitosan as a cationic polyelectrolyte and γ-PGA as an anionic polyelectrolyte; four groups of chitosan/γ-PGA PECs were synthesized according to the molar ratio of amine groups of chitosan to the carboxylic acid groups of γ-PGA. Different soft tissue responses to chitosan/γ-PGA PEC were observed between the epithelium and the muscle. In the epithelium, the wound dressed with chitosan/γ-PGA PEC healed faster than the control, with chitosan attracting polymorphonuclear (PMN) cells and γ-PGA creating a hydrophilic environment. In the muscle, a quantitative evaluation of the tissue response revealed that different degradation phenomena were evoked by different compositions of chitosan/γ-PGA PEC. After implantation for 28 days, the chitosan/γ-PGA PEC with chitosan dominating showed extensive surface erosion and superficial fragmentation surrounded by inflammatory cells, while chitosan/γ-PGA PECs with γ-PGA dominating elicited minimal degradation. These results confirm that the degradation of PECs can be controlled by tailoring the chitosan/γ-PGA PECs for different purposes. It appears that different local tissue conditions in muscle and epithelium may be involved in this difference.

    Abstract: Elevated arterial stiffness in patients with primary aldosteronism (PA) can be reversed after adrenalectomy; however, the effect of medical treatment with mineralocorticoid receptor antagonist (MRAs) is unknown. Objectives: The aim of this study was to evaluate the effect of MRAs and compare both treatment strategies on arterial stiffness in PA patients. Design: Prospective cohort study. Methods: We prospectively enrolled PA patients from 2006 to 2019 who received either adrenalectomy or MRA treatment (spironolactone). We compared their baseline and 1-year post-treatment biochemistry characteristics and arterial pulse wave velocity (PWV) to verify the effects of treatment and related determinant factors. Results: A total 459 PA patients were enrolled. After 1:1 propensity score matching for age, sex and blood pressure (BP), each group had 176 patients. The major determinant factors of baseline PWV were age and baseline BP. The adrenalectomy group had greater improvements in BP, serum potassium level, plasma aldosterone concentration, and aldosterone-to-renin ratio. The MRA group had a significant improvement in PWV after 1 year of treatment (1706.2 ± 340.05 to 1613.6 ± 349.51 cm/s, p  〈  0.001). There were no significant differences in post-treatment PWV ( p = 0.173) and improvement in PWV ( p = 0.579) between the adrenalectomy and MRA groups. The determinant factors for an improvement in PWV after treatment were hypertension duration, baseline PWV, and the decrease in BP. Conclusion: The PA patients who received medical treatment with MRAs had a significant improvement in arterial stiffness. There was no significant difference in the improvement in arterial stiffness between the two treatment strategies.

    Abstract: A new acoustic absorbing/cushioning composite is fabricated by thermoplastic polyurethanes honeycomb structure – thermoplastic polyurethane honeycomb cushion and grid, and composite nonwoven in this study. Composite nonwoven is composed of different layers of polyester/polypropylene nonwoven and polyester nonwoven. Research result shows that layer combination of polyester/polypropylene nonwoven and polypropylene nonwoven affects acoustic absorption and thermal conductivity of resulting composite nonwovens. The thermal conductivity of composite nonwovens decreases to 0.02213 W/(m K), showing excellent thermal-insulating property. Honeycomb structure–thermoplastic polyurethane honeycomb cushion and grid broadens the acoustic absorbed frequency and improves the mid- and high-frequency absorption coefficient and cushioning property of thermoplastic polyurethane/polyester/polypropylene composites. Incorporation of different honeycomb structure into composite nonwovens presents diversified acoustic-absorbing characteristic profiles. The resulting 35-mm-thick thermoplastic polyurethane/polyester/polypropylene composites absorb 85% acoustic waves at 1250 Hz and 94.2% at above 2000 Hz as well as 92.88–96.59% impact energy. Therefore, it becomes an excellent alternative for protective wall in kindergarten and gerocomium and compartment wall in the building.

    Abstract: In this study, far-infrared/anion-releasing elastic warp-knitted fabrics were successfully fabricated. Firstly, the composition and twist degree of ring-spun complex yarns that were made by rotor-twisting machine and ring-spinning frame were optimized based on twist contraction, hairiness, and tenacity measurements. The shell materials—1-ply bamboo charcoal (BC) roving, 1-ply phase change material (PCM) or the both (BC/PCM), and the core material—BC/stainless steel (BC/SS) wrap yarn, were formed into different compositions of ring-spun complex yarns. Afterward, elastic warp-knitted fabrics were fabricated using the optimized complex yarns as weft yarns, and rubber threads and polyester (PET) filaments as warp yarns. Air permeability, far-infrared emissivity, and anion amount of resulting warp-knitted fabrics were evaluated. Ring-spun complex yarn result shows that, twist contraction rate ratio increased, but hairiness decreased with increase of twist degree. Tenacity of ring-spun complex yarn made by BC roving (Type A) or PCM roving (Type B) first increased and then decreased with twist degree. However, when 1-ply BC and 1-ply PCM rovings were used as shell materials, the tenacity of resulting ring-spun complex yarn (Type C) decreased with twist degrees. Consequently, 12 twists per inch (T.P.I.) was the optimal twist degree for the following fabrication of warp-knitted fabrics. Air permeability, far-infrared emissivity, and anion amount of elastic warp-knitted fabrics composed of BC/SS wrap yarn and BC roving reached 44.35 cm 3 /s/cm 2 , 0.94ɛ and 420 counts/cm 3 , respectively, indicating excellent breathability and far-infrared/anion-releasing health care functions.

    Abstract: A nonwoven is an ideal sound-absorbing material due to its high surface area. Surface area of a nonwoven correlates with fiber denier and packing density, and affects the sound absorbing property. With smaller denier, sound waves have great chance to interact with fibers. Moreover, more fibers would produce friction in-between sound waves at high packing density. Besides, a large amount of fabrics are produced in the current textile industry. During the production process, selvages are cut form fabrics and then abandoned, thus leading to amazing wastes after a long period of discarding. This study used recycled selvage fiber to prepare composite nonwovens, and then compounded with polyurethane foam, forming sound-absorbing/flame-retarding composite planks. Porous and vibration absorbing mechanism was combined for improving sound the absorbing property. And effects of fiber denier, needle-punched density for nonwoven and foam density of PU foam on properties including sound-absorbing and flame-retarding are discussed. Results show that the sound absorption coefficient of the resultant composite plank was above 0.8 at medium frequency. Superficial composite nonwoven achieved the effect of delayed burning time.

    Abstract: Research on the simulation and modeling of dynamic puncture penetration is more complex problem due to full consideration of the tightness of the fabric and the sharp profile of the puncture. This study presents numerical simulation of complicated dynamic puncture behaviors on the basis of the roles of extension and stress-wave transmission on the deformation. The unit cell model was used to simulate the yarn crimp and extension during the uniaxial dynamic puncture process. In addition, the puncture deformation and stress distribution of woven fabrics with different elastic modulus and friction distance were simulated followed with dynamic puncture penetration. The result shows that dynamic puncture damage critically depends on the elastic modulus of yarns and the distance between yarns; the inter-yarn distance affects dynamic puncture resistance more significantly. Dynamic puncture stress nonlinearly increases with the elastic modulus, and linearly decreases with yarn distance. The research result indicates that weaving density can be increased to improve dynamic puncture resistance more obviously.
