Different cultures in recent years have developed towards a translation turn, which made a great contribution to relocate national or local cultures being localized to become regional or global cultures. As China grows quickly economically integrating into the world, it becomes urgent to relate China’s story and disseminate the Chinese culture. Due to the weaknesses and drawbacks of different existing cultural translation theories for Chinese culture to go out, a new perspective on translation turn for the go-out of Chinese culture should be drawn to spread better and disseminate Chinese culture to other countries. Based on the existing cultural translation theories, the equivalence of ideology, style of the translator and agency of the support are proposed to draw a new perspective: an innovative poly-system theory for Chinese culture translation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20translation%20theory" title="cultural translation theory">cultural translation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20culture" title=" Chinese culture"> Chinese culture</a>, <a href="https://publications.waset.org/abstracts/search?q=innovative%20poly%20system" title=" innovative poly system"> innovative poly system</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20cultures" title=" global cultures"> global cultures</a> </p> <a href="https://publications.waset.org/abstracts/57358/an-innovative-poly-system-theory-for-the-go-out-of-chinese-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57358.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">453</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19591</span> Preconcentration and Determination of Lead Ion in Environmental Samples by Poly Urea-Formaldehyde</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elham%20Moniri">Elham Moniri</a>, <a href="https://publications.waset.org/abstracts/search?q=Parvane%20Bozorgniya"> Parvane Bozorgniya</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Shahbazi"> Hamidreza Shahbazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, poly urea-formaldehyde was prepared.

This work focuses towards understanding interaction of harmalol, a dihydro beta-carboline alkaloid, with different nucleic acid motifs viz. double stranded CT DNA, single stranded A-form poly(A), double-stranded A-form of poly(C)·poly(G) and clover leaf tRNAphe by different spectroscopic, calorimetric and molecular modeling techniques. Results of this study converge to suggest that (i) binding constant varied in the order of CT DNA > poly(C)·poly(G) > tRNAphe > poly(A), (ii) non-cooperative binding of harmalol to poly(C)·poly(G) and poly(A) and cooperative binding with CT DNA and tRNAphe, (iii) significant structural changes of CT DNA, poly(C)·poly(G) and tRNAphe with concomitant induction of optical activity in the bound achiral alkaloid molecules, while with poly(A) no intrinsic CD perturbation was observed, (iv) the binding was predominantly exothermic, enthalpy driven, entropy favoured with CT DNA and poly(C)·poly(G) while it was entropy driven with tRNAphe and poly(A), (v) a hydrophobic contribution and comparatively large role of non-polyelectrolytic forces to Gibbs energy changes with CT DNA, poly(C)·poly(G) and tRNAphe, and (vi) intercalated state of harmalol with CT DNA and poly(C)·poly(G) structure as revealed from molecular docking and supported by the viscometric data. Furthermore, with competition dialysis assay it was shown that harmalol prefers hetero GC sequences. All these findings unequivocally pointed out that harmalol prefers binding with ds CT DNA followed by ds poly(C)·poly(G), clover leaf tRNAphe and least with ss poly(A). The results highlight the importance of structural elements in these natural beta-carboline alkaloids in stabilizing different DNA and RNA of various motifs for developing nucleic acid based better therapeutic agents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calorimetry" title="calorimetry">calorimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%2FRNA-alkaloid%20interaction" title=" DNA/RNA-alkaloid interaction"> DNA/RNA-alkaloid interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=harmalol" title=" harmalol"> harmalol</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopy" title=" spectroscopy"> spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/55814/biophysical-study-of-the-interaction-of-harmalol-with-nucleic-acids-of-different-motifs-spectroscopic-and-calorimetric-approaches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55814.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19589</span> Poly Urea-Formaldehyde for Preconcentration and Determination of Cadmium Ion in Environmental Samples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Homayon%20Ahmad%20Panahi">Homayon Ahmad Panahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Samira%20Tajik"> Samira Tajik</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Hadi%20Dehghani"> Mohamad Hadi Dehghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Khezri"> Mostafa Khezri</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Moniri"> Elham Moniri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, poly urea-formaldehyde was prepared.

Thornton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The dual stimuli-controlled release of doxorubicin from gel-embedded nanoparticles is reported. Non-cytotoxic polymer nanoparticles are formed from poly(ethylene glycol)-b-poly(benzyl glutamate) that, uniquely, contain a central ester link. This connection renders the nanoparticles pH-responsive, enabling extensive doxorubicin release in acidic solutions (pH 6.5), but not in solutions of physiological pH (pH 7.4). Doxorubicin loaded nanoparticles were found to be stable for at least 31 days and lethal against the three breast cancer cell lines tested. Furthermore, doxorubicin-loaded nanoparticles could be incorporated within a thermoresponsive poly(2-hydroxypropyl methacrylate) gel depot, which forms immediately upon injection of poly(2-hydroxypropyl methacrylate) into aqueous solution. The combination of the poly(2-hydroxypropyl methacrylate) gel and poly(ethylene glycol)-b-poly(benzyl glutamate) nanoparticles yields an injectable doxorubicin delivery system that facilities near-complete drug release when maintained at elevated temperatures (37 °C) in acidic solution (pH 6.5). In contrast, negligible payload release occurs when the material is stored at room temperature in a non-acidic solution (pH 7.4). The system has great potential as a vehicle for the prolonged, site-specific release of chemotherapeutics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title="biodegradable">biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoresponsive" title=" thermoresponsive"> thermoresponsive</a> </p> <a href="https://publications.waset.org/abstracts/123917/meticulous-doxorubicin-release-from-ph-responsive-nanoparticles-entrapped-within-an-injectable-thermoresponsive-depot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123917.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19587</span> Thermal Stabilisation of Poly(a)•Poly(U) by TMPyP4 and Zn(X)TMPyP4 Derivatives in Aqueous Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Kudrev">A.

The absorbance data matrices were analyzed with a versatile chemometric procedure that provides the melting profile (distribution of species) and the pure spectrum for each chemical species present along the heating experiment. As revealed by the increase of Tm, the duplex structure was stabilized by these porphyrins. The values of stabilization temperature ΔTm in the presence of these porphyrins are relatively large, 1.2-8.4 °C, indicating that the porphyrins contribute differently in stabilizing the duplex Poly(A)-Poly(U) structure. Remarkable is the fact that the porphyrin TMPyP4 was less effective in the stabilization of the duplex structure than the metalloporphyrin Zn(X)TMPyP4 which suggests that metallization play an important role in porphyrin-RNA binding. Molecular Dynamics Simulations has been used to illustrate melting of the duplex dsRNA bound with a porphyrin molecule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melting" title="melting">melting</a>, <a href="https://publications.waset.org/abstracts/search?q=Poly%28A%29-Poly%28U%29" title=" Poly(A)-Poly(U)"> Poly(A)-Poly(U)</a>, <a href="https://publications.waset.org/abstracts/search?q=TMPyP4" title=" TMPyP4"> TMPyP4</a>, <a href="https://publications.waset.org/abstracts/search?q=Zn%28X%29TMPyP4" title=" Zn(X)TMPyP4"> Zn(X)TMPyP4</a> </p> <a href="https://publications.waset.org/abstracts/75747/thermal-stabilisation-of-polyapolyu-by-tmpyp4-and-znxtmpyp4-derivatives-in-aqueous-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19586</span> Increase in Specificity of MicroRNA Detection by RT-qPCR Assay Using a Specific Extension Sequence </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyung%20Jin%20Kim">Kyung Jin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiwon%20Kwak"> Jiwon Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Hoon%20Lee"> Jae-Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo%20Suk%20Lee"> Soo Suk Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We describe an innovative method for highly specific detection of miRNAs using a specially modified method of poly(A) adaptor RT-qPCR. We use uniquely designed specific extension sequence, which plays important role in providing an opportunity to affect high specificity of miRNA detection. This method involves two steps of reactions as like previously reported and which are poly(A) tailing and reverse-transcription followed by real-time PCR. Firstly, miRNAs are extended by a poly(A) tailing reaction and then converted into cDNA. Here, we remarkably reduced the reaction time by the application of short length of poly(T) adaptor. Next, cDNA is hybridized to the 3’-end of a specific extension sequence which contains miRNA sequence and results in producing a novel PCR template. Thereafter, the SYBR Green-based RT-qPCR progresses with a universal poly(T) adaptor forward primer and a universal reverse primer. The target miRNA, miR-106b in human brain total RNA, could be detected quantitatively in the range of seven orders of magnitude, which demonstrate that the assay displays a dynamic range of at least 7 logs. In addition, the better specificity of this novel extension-based assay against well known poly(A) tailing method for miRNA detection was confirmed by melt curve analysis of real-time PCR product, clear gel electrophoresis and sequence chromatogram images of amplified DNAs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microRNA%28miRNA%29" title="microRNA(miRNA)">microRNA(miRNA)</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20extension%20sequence" title=" specific extension sequence"> specific extension sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-qPCR" title=" RT-qPCR"> RT-qPCR</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28A%29%20tailing%20assay" title=" poly(A) tailing assay"> poly(A) tailing assay</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20transcription" title=" reverse transcription"> reverse transcription</a> </p> <a href="https://publications.waset.org/abstracts/66836/increase-in-specificity-of-microrna-detection-by-rt-qpcr-assay-using-a-specific-extension-sequence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66836.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19585</span> Polyhedral Oligomeric Silsesquioxane in Poly Lactic Acid and Poly Butylene Adipate-Co-Terephthalate Blend</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elahe%20Moradi">Elahe Moradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoseinali%20A.%20Khonakdar"> Hoseinali A.

In our study, we endeavored to make a significant contribution to environmental conservation by introducing an eco-friendly structure, developed through an innovative approach. Specifically, we enhanced the compatibility between two immiscible polymers, namely poly (lactic acid) (PLA) and poly (butylene adipate-co-terephthalate) (PBAT). Our strategy involved the use of polyhedral oligomeric silsesquioxanes (POSS) nanoparticles, equipped with an epoxy functional group (Epoxy-POSS), to accomplish this objective with solution casting method. The incorporation of 1% nanoparticles into the PLA blend resulted in a decrease in its cold crystallization temperature. Furthermore, these nanoparticles possess the requisite capability to enhance molecular mobility, facilitated by the induction of a lubrication effect. The emergence of a PLA-CO-POSS-CO-PBAT structure at the interface between PLA and PBAT led to a significant amplification of the interactions at the interface of the matrix and the dispersed phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compatibilization" title="compatibilization">compatibilization</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20behavior" title=" thermal behavior"> thermal behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=structure-properties" title=" structure-properties"> structure-properties</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=PLA" title=" PLA"> PLA</a>, <a href="https://publications.waset.org/abstracts/search?q=PBAT" title=" PBAT"> PBAT</a> </p> <a href="https://publications.waset.org/abstracts/179141/polyhedral-oligomeric-silsesquioxane-in-poly-lactic-acid-and-poly-butylene-adipate-co-terephthalate-blend" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179141.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">53</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19584</span> EU Innovative Economic Priorities, Contemporary Problems and Challenges of Its Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gechbaia%20Badri">Gechbaia Badri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper discusses in today's world of economic globalization and development of innovative economic integration is one of the issues of the day in the world.

This biopolymer can be used in the packaging industry very often. Poor resistance to permeation of gases is the disadvantage of poly (lactic acid). The permeability of gases and vapor through the films applied for packages and bottles generally should be very low to prolong products shelf-life. We propose innovation method of PLA gas barrier modification using electromagnetic radiation in ultraviolet range. Poly (lactic acid) (PLA) and multifunctional acrylate monomers were mixed in different composition. Final films were obtained by photochemical reaction (photocrosslinking). We tested permeability to water vapor and carbon dioxide through these films. Also their resistance to UV radiation was also studied. The samples were conditioned in the activated sludge and in the natural soil to test their biodegradability. An innovative method of PLA modification allows to expand its usage, and can reduce the future costs of waste management what is the result of consuming such materials like PET and HDPE. Implementation of our material for packaging will contribute to the protection of the environment from the harmful effects of extremely difficult to biodegrade materials made from PET or other plastic <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interpenetrating%20polymer%20network" title="interpenetrating polymer network">interpenetrating polymer network</a>, <a href="https://publications.waset.org/abstracts/search?q=packaging%20films" title=" packaging films"> packaging films</a>, <a href="https://publications.waset.org/abstracts/search?q=photocrosslinking" title=" photocrosslinking"> photocrosslinking</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylates%20dipentaerythritol%20pentaacrylate%20DPEPA" title=" polyacrylates dipentaerythritol pentaacrylate DPEPA"> polyacrylates dipentaerythritol pentaacrylate DPEPA</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%20%28lactic%20acid%29" title=" poly (lactic acid)"> poly (lactic acid)</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20biodegradation" title=" polymer biodegradation "> polymer biodegradation </a> </p> <a href="https://publications.waset.org/abstracts/24623/polyacrylates-in-poly-lactic-acid-matrix-new-biobased-polymer-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24623.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">478</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19582</span> Properties of Poly(Amide-Imide) with Low Residual Stress for Electronic Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwangin%20Kim">Kwangin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Taewon%20Yoo"> Taewon Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Haksoo%20Han"> Haksoo Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polyimide is a superior polymer in the electronics industry, and we conducted a study to synthesize poly(amide-imide) at low temperatures.

Test results indicated that the inclusion of poly-lactic acid decreased the PH value of concrete and all the poly-lactic acid particles were dissolved due to the formation of sodium lactide and lactide oligomers when subjected to the high alkaline environment of concrete. In addition, an increase in thermal conductivity value of concrete was observed as the ratio of poly-lactic acid increased.

The research focused on enhancing the compatibility between two immiscible polymers, poly (lactic acid) (PLA) and poly (butylene adipate-co-terephthalate) (PBAT), using polyhedral oligomeric silsesquioxanes (POSS) nanoparticles with an epoxy functional group (Epoxy-POSS). This was achieved through a solution casting method. The study found that the modulus in the glassy region for blends containing Epoxy-POSS was significantly higher than that of the PLA/PBAT blend without Epoxy-POSS. However, in the transition and rubbery regions, the modulus of the Epoxy-POSS-containing blends was only marginally greater. From a mechanical properties’ perspective, the study demonstrated that the incorporation of POSS-EPOXY at varying concentrations enhanced the tensile strength of the PLA/PBAT blend by 30%, thereby acting as a reinforcement. This finding underscores the potential of this approach in the development of renewable polymers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Polyhedral%20oligomeric%20silsesquioxane" title="Polyhedral oligomeric silsesquioxane">Polyhedral oligomeric silsesquioxane</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behavior" title=" mechanical behavior"> mechanical behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=PLA" title=" PLA"> PLA</a>, <a href="https://publications.waset.org/abstracts/search?q=PBAT" title=" PBAT"> PBAT</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a> </p> <a href="https://publications.waset.org/abstracts/179381/poly-lactic-acidpoly-butylene-adipate-co-terephthalate-films-reinforced-with-polyhedral-oligomeric-silsesquioxane-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179381.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">62</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19578</span> Innovative Three Wire Capacitor Circuit System for Efficiency and Comfort Improvement of Ceiling Fans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20K.%20Saket">R.

Education levels of poly house farmers are high compared to open field farmers, where 57.14% poly house farmers are high school educated, whereas 35% open field farmers are illiterates. Majority farmers use nursery of 35 days and grow in <0.5 acre poly house in summer and rabi and < 1 acre in open field during kharif. Awareness on pesticide related issues is varying among poly house and open field farmers with some commonality, where 28.57% poly house farmers know about recommended pesticides while only 10% open field farmers are aware of this issue. However, in general, all farmers contact pesticide dealer for recommendations, poly house farmers prefer to contact scientists (35.71%) and open field farmers prefer to contact agricultural officers (33.33). Most farmers are unaware about pesticide classification and toxicity symbols on packing. Farmers are aware about endosulfan ban, but only 21.42% poly house and 11.66% open field farmers know about ban of monocrotofos on vegetables.

Statins have shown potential for osteoporosis and to promote fracture healing. The effects of statin can be further potentiated by combining it with a carrier known as poly-(DL-lactide), which would provide persistent release of statin to the fracture site. This study was designed to investigate the effects of direct injection of poly-(DL-lactide)-incorporated lovastatin on fracture healing of postmenopausal osteoporosis rat model. Twenty-four Sprague-Dawley female rats were divided into 3 groups: sham-operated (SO), ovariectomized-control rats (OVxC) and poly-(DL-lactide)-incorporated lovastatin (OVx+Lov) groups. The OVx+Lov group was given a single injection of 750 µg/kg lovastatin particles incorporated with poly-(DL-lactide). After 4 weeks, the fractured tibiae were dissected out for biomechanical assessments of the callus. The OVx+Lov group showed significantly better callus strength than the OVxC group (p<0.05). In conclusion, a single injection of lovastatin-incorporated poly-(DL-lactide) was able to promote better fracture healing of osteoporotic bone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=statins" title="statins">statins</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20healing" title=" fracture healing"> fracture healing</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title=" osteoporosis"> osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=poly-%28DL-lactide%29" title=" poly-(DL-lactide)"> poly-(DL-lactide)</a> </p> <a href="https://publications.waset.org/abstracts/9413/improval-of-fracture-healing-of-osteoporotic-bone-by-lovastatin-incorporated-poly-dl-lactide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">506</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19572</span> Biologically Active Caffeic Acid-Derived Biopolymer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Barbakadze">V.

Dendrimers are novel three dimensional hyper branched globular nanopolymeric architectures. Drug delivery scientists are especially enthusiastic about possible utility of dendrimers as drug delivery tool. Dendrimers like poly L lysine (PLL), poly-propylene imine (PPI) and poly-amidoamine (PAMAM), etc., are used as gene carrier in drug delivery system because of their chemical characteristics. These characteristics of chemical compounds are analysed using topological indices (invariants under graph isomorphism) such as Wiener index, Zagreb index, etc., Prof. V. R. Kulli motivated by the application of Zagreb indices in finding the total π energy and derived Gourava indices which is an improved version over Zagreb indices. In this paper, we study the structure of PLL-Dendrimer that has the following applications: reduction in toxicity, colon delivery, and topical delivery. Also, we determine first and second Gourava indices, first and second hyper Gourava indices, product and sum connectivity Gourava indices for PLL-Dendrimer.

We wish to report herein the facile synthesis of fully bio-based bisphenols containing pendant furyl group by base-catalyzed condensation of furfural with guaiacol. Bisphenols possessing pendant furyl group represent valuable monomers for the synthesis of a range of polymers which include epoxy resins, polyesters, polycarbonates, poly(aryl ether)s, etc. Several new homo/co-poly(arylene ether sulfone)s have been prepared by the reaction of 4,4(-fluorodiphenyl sulfone (FDS) with 4,4'-(furan-2-ylmethylene)bis(2-methoxyphenol) (BPF) and 4,4(-isopropylidenediphenol (BPA) using different molar ratios of bisphenols. Poly(arylene ether sulfone)s showed inherent viscosities in the range 0.92-1.47 dLg-1 and number average molecular weights (Mn), obtained from gel permeation chromatography (GPC), were in the range 91,300 – 1,31,000. Poly(arylene ether sulfone)s could be cast into tough, transparent and flexible films from chloroform solutions. X-Ray diffraction studies indicated amorphous nature of poly(arylene ether sulfone)s. Poly(arylene ether sulfone)s showed Tg values in the range 179-191 oC. Additionally, the pendant furyl groups in poly(arylene ether sulfone)s provide reactive sites for chemical modifications and cross-linking via Diels-Alder reaction with maleimides and bismaleimides, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-based" title="bio-based">bio-based</a>, <a href="https://publications.waset.org/abstracts/search?q=bisphenols" title=" bisphenols"> bisphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=Diels-Alder%20reaction" title=" Diels-Alder reaction"> Diels-Alder reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28arylene%20ether%20sulfone%29s" title=" poly(arylene ether sulfone)s"> poly(arylene ether sulfone)s</a> </p> <a href="https://publications.waset.org/abstracts/62434/synthesis-of-bisphenols-containing-pendant-furyl-group-based-on-chemicals-derived-from-lignocellulose-and-their-utilization-for-preparation-of-clickable-polyarylene-ether-sulfones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62434.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">256</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19566</span> Modified Poly (Pyrrole) Film-Based Biosensors for Phenol Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Korkut">S.

Bio-nanocomposite films were prepared using the solvent casting method, with cellulose content ranging from 1 to 3 wt%. During the solution casting method, 15 ml of chloroform was used to dissolve an overall mass of 0.5g of each polymer as well as the combination of their bio-nanocomposites. Comprehensive analysis was conducted using FTIR, SEM, TEM, DSC, TGA, and XRD to assess morphological, thermal, and structural properties. Mechanical properties were not investigated due to the thin nature of the films. The results indicated significant improvements in the thermal stability and morphological properties with increasing cellulose content, showcasing the potential of these materials for tissue engineering applications. The use of cellulose extracted from a medicinal plant highlights the potential for sustainable and biocompatible materials in biomedical applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-nanocomposites" title="bio-nanocomposites">bio-nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%20%28butylene%20succinate%29" title=" poly (butylene succinate)"> poly (butylene succinate)</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28%D4%91-caprolactone%29" title=" poly(ԑ-caprolactone)"> poly(ԑ-caprolactone)</a>, <a href="https://publications.waset.org/abstracts/search?q=Eucomis%20autumnalis" title=" Eucomis autumnalis"> Eucomis autumnalis</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plant" title=" medicinal plant"> medicinal plant</a> </p> <a href="https://publications.waset.org/abstracts/183437/fabrication-and-assessment-of-poly-butylene-succinatepoly-caprolactoneeucomis-autumnalis-cellulose-bio-composites-for-tissue-engineering-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183437.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">51</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19563</span> Mechanical Properties of Recycled Plasticized PVB/PVC Blends</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Tup%C3%BD">Michael Tupý</a>, <a href="https://publications.waset.org/abstracts/search?q=Dagmar%20M%C4%9B%C5%99%C3%ADnsk%C3%A1"> Dagmar Měřínská</a>, <a href="https://publications.waset.org/abstracts/search?q=Alice%20Tesa%C5%99%C3%ADkov%C3%A1-Svobodov%C3%A1"> Alice Tesaříková-Svobodová</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Carrot"> Christian Carrot</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Pillon"> Caroline Pillon</a>, <a href="https://publications.waset.org/abstracts/search?q=V%C3%ADt%20Petr%C3%A1nek"> Vít Petránek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mechanical properties of blends consisting of plasticized poly(vinyl butyral) (PVB) and plasticized poly(vinyl chloride) (PVC) are studied, in order to evaluate the possibility of using recycled PVB waste derived from windshields. PVC was plasticized with 38% of diisononyl phthalate (DINP), while PVB was plasticized with 28% of triethylene glycol, bis(2-ethylhexanoate) (3GO). The optimal process conditions for the PVB/PVC blend in 1:1 ratio were determined. Entropy was used in order to theoretically predict the blends miscibility. The PVB content of each blend composition used was ranging from zero to 100%. Tensile strength and strain were tested. In addition, a comparison between recycled and original PVB, used as constituents of the blend, was performed. <p class="card-text"><strong>Keywords:</strong> <a
