Authors: Saensuk Mongkol , Witchakool Suwiwat , Choompol Atchara 
Published: May 2024

Fake news has emerged as a pervasive issue within the modern information ecosystem, leading to widespread dissemination of misinformation and erosion of trust. This paper introduces a novel hybrid approach for effectively detecting fake news in the Thai language by combining the CRITIC method with multiple machine learning models. The initial step involves collecting Thai-language fake news data from websites. Subsequently, the data undergoes a preprocessing phase. In the second step, the preprocessed data is used for validation through three basic machine learning models, namely, Naive Bayes, Decision Tree, and K-Nearest Neighbors. In the third step, the accuracy results from these three models are employed to calculate the significance weights of each model using the CRITIC method. In the final step, predictions are recalculated using the proposed method. The proposed method achieves an 83.37% accuracy, surpassing Naive Bayes (80.83%), Decision Tree (80.37%), and K-Nearest Neighbors (75.75%). This indicates a significant enhancement in performance, with the proposed method outperforming the established models by up to 7.62%. Consequently, the proposed method can enhance the performance of fake news detection in Thai language by utilizing an ensemble of the original models. A significant advantage of this approach is its simplicity coupled with high efficacy. It is postulated that this method can be adapted for detecting fake news in other languages as well.

A study was conducted at the Agricultural Research Station (UAS, Dharwad), Sankeshwar, Karnataka during Kharif 2022-23 to assess the effectiveness of different insecticides against soybean leaf folder, Omiodes indicata. Among five treatments, lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC @ 0.4 ml l-1 exhibited the lowest mean population of soybean leaf folder, Omiodes indicata on 5th and 10th day after spray with 2.12 and 0.98 larval population per meter row length, respectively which was followed by emamectin benzoate 5 % SG @ 0.3 g l-1 (3.03 and 1.83 larvae per meter row length). Lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC was found to be the best effective treatment with 81.97 % reduction over control followed by emamectin benzoate 5 SG (71.61 %). Similar results were obtained with per cent defoliation.
Multiferroics with Spiral Spin Orders
Authors: Tokura Yoshinori , Seki Shinichiro 
Published: December 2009

AbstractCross correlation between magnetism and electricity in a solid can host magnetoelectric effects, such as magnetic (electric) induction of polarization (magnetization). A key to attain the gigantic magnetoelectric response is to find the efficient magnetism–electricity coupling mechanisms. Among those, recently the emergence of spontaneous (ferroelectric) polarization in the insulating helimagnet or spiral‐spin structure was unraveled, as mediated by the spin‐exchange and spin–orbit interactions. The sign of the polarization depends on the helicity (spin rotation sense), while the polarization direction itself depends on further details of the mechanism and the underlying lattice symmetry. Here, we describe some prototypical examples of the spiral‐spin multiferroics, which enable some unconventional magnetoelectric control such as the magnetic‐field‐induced change of the polarization direction and magnitude as well as the electric‐field‐induced change of the spin helicity and magnetic domain.
Technical note: A new three‐dimensional technique for high resolution quantitative recording of perikymata
Authors: Bocaege E. , Humphrey L.T. , Hillson S. 
Published: December 2009

AbstractThe number and spacing of incremental markings at the enamel surface, known as perikymata, are considered important indicators of dental growth patterns, as they provide information on crown formation times and the underlying developmental processes. This study explores the potential of a new three‐dimensional technique for the reconstruction of dental growth profiles, using teeth from a medieval child from Abingdon, Oxfordshire. The crowns of three anterior teeth were imaged and analyzed using the Alicona 3D InfiniteFocus imaging microscope. Individual perikyma grooves can be unambiguously identified on a profile of the reconstructed enamel surface and direct distances between successive pairs of perikyma grooves can be calculated from coordinate data. This quantitative approach constitutes a more objective way to record perikymata spacing than current methods. Am J Phys Anthropol 2010. © 2009 Wiley‐Liss, Inc.
Reversible electrical behavior with strain for a carbon black‐filled rubber
Authors: Jha V. , Thomas A. G. , Bennett M. , Busfield J. J. C. 
Published: December 2009

AbstractMost unfilled elastomers exhibit a high electrical resistance. Fillers are usually added to elastomers to enhance their mechanical properties. Frequently the filler type used is an electrically conductive carbon black and the inclusion of such fillers reduces the resistivity of the elastomer compound. Previous work has shown that for elastomers containing high abrasion furnace, carbon black fillers such as N330 (or N300 series) at a volume fraction above the percolation threshold the resistivity changes with strain, the precise resistivity versus strain behavior being nonlinear and irreversible for conventional carbon black fillers. A strain‐measuring device, deriving strain directly from a measure of the resistivity, requires that the behavior be reversible and reproducible from cycle to cycle. This work presents the electrical resistivity behavior of a natural rubber (NR) compound filled with Printex XE2 carbon black. This type of filler has a significantly different morphology to the N300 series blacks examined previously. The Printex was incorporated into the rubber at a volume fraction above its percolation threshold and its behavior is contrasted to that observed with N300 series carbon black‐filled NR. Here, and for the first time, reversible electrical resistivity dependence with strain is reported for an elastomer filled with Printex XE2. This reversible behavior under strain opens up the possibility of applications, such as a flexible load sensor, pressure sensor, or switch. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Synthesis, characterization, and coordination behavior of copoly(styrene‐maleimide) functionalized with terpyridine
Authors: Koohmareh Gholam Ali , Sharifi Morteza 
Published: December 2009

AbstractA maleimide functionalized terpyridine, 4′(4‐maleimidophenyl)‐2, 2′ : 6′, 2″‐terpyridine, was synthesized and copolymerized with styrene via radical polymerization. The synthesized monomer was characterized by CHN elemental analysis, FT‐IR, 1H NMR, and Mass spectrometry. The structure of polymer was also confirmed by FT‐IR and UV‐Vis spectroscopy. The resulting polymer was soluble in chloroform and polar aprotic solvents, and showed an inherent viscosity of 1.5 dL/g in N,N‐dimethyl formamide at 25°C. The polymer solution in CHCl3/methanol showed a metal‐ligand charge‐transfer band of 586 nm upon addition of Fe(II) ion, exhibiting that coordination between terpyridine units and Fe(II) had occurred. The thermal stability of polymer before and after complexation with Fe(II) was examined by thermogravimetric analysis. For polymer before complexation, the weight loss started at 180°C whereas for complexed polymer it started at 260°C, which demonstrates good thermal stability of complexed polymer. © 2009 Wiley Periodicals, Inc.

Graft copolymerization of acrylonitrile and its amidoxime derivative onto chitosan
Authors: Mohamed Riham Rashad , Sabaa Magdy Wadid 
Published: December 2009

AbstractAcrylonitrile (AN) was investigated as an important monomer for the graft copolymerization onto chitosan. A number of variables in the grafting reaction were investigated, including initiator and monomer concentration, duration, and temperature of the polymerization reaction. The graft copolymers were evaluated in terms of graft yield, grafting efficiency and % homopolymer. Moreover, modification of grafted chitosan was done by changing the nitrile group (CN) to the amidoxime group (CNOH). Certain characterization for both the grafted Chitosan (Ch‐g‐PAN) and its amidoxime derivative ‐as compared to the parent polymer‐ are measured including the swell ability property, dye uptake, surface morphology, and metal uptake property. The results obtained reflect the feasibility for using Ch‐g‐PAN as absorbent for both Ni2+ and Co2+ ions. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010

Authors: Cao Yan , Li Huiquan , Zhang Yi , Zhang Jun , He Jiasong 
Published: December 2009

AbstractCornhusk cellulose was regenerated using the ionic liquids viz., 1‐allyl‐3‐methylimidazolium chloride (AmimCl) and 1‐ethyl‐3‐methylimidazolium acetate (EmimAc). The cast cellulose films were characterized by FTIR, WAXD and SEM techniques. Their mechanical properties were also studied. These studies indicated that AmimCl and EmimAc are good solvents for the regeneration of cornhusk cellulose. The regenerated cornhusk cellulose (RCC) was found to be cellulose (II) with dense structure. The films cast from AmimCl exhibited good mechanical properties; the tensile modulus and strength were as high as 6 GPa and 120 MPa respectively, whereas these values for those films cast using EmimAc were found to be 4.1 GPa and 47 MPa respectively. Further, it was observed that after regeneration, the solvents could be effectively recycled. Thus a novel nonpolluting process of forming RCC films from agricultural waste was developed. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Synthesis of starch esters in ionic liquids
Authors: Xie Wenlei , Shao Li , Liu Yawei 
Published: December 2009

AbstractChemical modification of corn starches with succinic anhydride or acetic anhydride was carried out using 1‐butyl‐3‐methylimidazolium chloride (BMIMCl) as a reaction medium. The reaction progress was followed in terms of the degree of substitution (DS) for the starch derivatives. The results showed that the homogeneous esterification of starch at 5 : 1 molar ratio of anhydride/anhydroglucose units at 100°C led to formation of acetates with DS ranging from 0.37 to 2.35 and succinates with DS ranging from 0.03 to 0.93. Moreover, the reaction media applied could be easily recycled and reused. Further, the formation of starch esters was confirmed by the presence of the carbonyl signal in the FTIR and NMR spectra. It was shown that the starch granules were mostly converted from their crystalline structure into amorphous state in the ionic liquid system under the given reaction conditions. © 2009 Wiley Periodicals, Inc.

Effect of the processing parameters on the surface resistivity of acrylonitrile–butadiene rubber/multiwalled carbon nanotube nanocomposites
Authors: Cho Byung‐Mook , Kim Gue‐Hyun 
Published: December 2009

AbstractIn this study, acrylonitrile–butadiene rubber (NBR) was melt‐mixed with multiwalled carbon nanotubes (MWCNTs). Because the electrical conductivity and mechanical properties of composites are strongly influenced by the filler's state of dispersion and the extent of filler breakage during processing, the processing conditions are very important parameters. The effects of the mixing time, rotor speed, cooling rate, and sulfur concentration on the surface resistivity were investigated. Increasing the rotor speed from 20 to 60 rpm at mixing times of 15 and 30 min led to an increase in the surface resistivity from around 104 to 1011 Ω/square. However, at a mixing time of 7 min, the surface resistivity slightly decreased with increasing rotor speed. When slow cooling was applied, a surface resistivity of 104 Ω/square was obtained at around 2‐phr MWCNTs. However, when the fast cooling was applied, a surface resistivity of 106 Ω/square was obtained at 5‐phr MWCNTs. The tensile strength and tensile modulus at 300% elongation were improved with the addition of MWCNTs into NBR. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Effect of the filler size and content on the thermomechanical properties of particulate aluminum nitride filled epoxy composites
Authors: Yung K. C. , Zhu B. L. , Yue T. M. , Xie C. S. 
Published: December 2009

AbstractPolymer matrix composites based on brominated epoxy as the matrix and aluminum nitride (AlN) particles as the filler were prepared. The influences of the size, content, and size distribution of AlN on the thermomechanical properties, including the glass‐transition temperature (Tg), coefficient of thermal expansion (CTE), dynamic storage modulus (E′), dynamic loss modulus (E″), and loss factor (tan δ), of the composites were investigated by thermomechanical analysis and dynamic mechanical analysis. There was a total change trend for Tg; that is, Tg of the composites containing nano‐aluminum nitride (nano‐AlN; 50 nm) was lower than that of the micro‐aluminum nitride (micro‐AlN; 2.3 μm) filled composites, especially at high nano‐AlN contents. The Tg depression of the composites containing nano‐AlN was related to the aggregation of nano‐AlN and voids in the composites. On the other hand, the crosslink density of the epoxy matrix decreased for nano‐AlN‐filled composites, which also resulted in a Tg depression. The results also show that E′ and E″ increased, whereas tan δ and CTE of the composites decreased, with increasing the AlN content or increasing nano‐AlN fraction at the same AlN content. These results indicate that increasing the interfacial areas between AlN and the epoxy matrix effectively enhanced the dynamic modulus and decreased CTE. In addition, at a fixed AlN content of 10 wt %, a low E′ of pre‐Tg (before Tg temperature) and high Tg were observed at the smaller weight ratio of nano‐AlN when combinations of nano‐AlN plus micro‐AlN were used as the filler. This may have been related to the best packing efficiency at that weight ratio when the bimodal filler was used. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Poly(vinyl chloride)/metallic oxides/organically modified montmorillonite nanocomposites: Preparation, morphological characterization, and modeling of the mechanical properties
Authors: Rodolfo Antonio , Innocentini‐Mei Lucia Helena 
Published: December 2009

AbstractPoly(vinyl chloride), metallic oxides (from copper, molybdenum, and zinc), and organically modified montmorillonite (O‐MMT) nanocomposites were prepared in a melt‐blending or intercalation‐in‐the‐molten‐state process. The morphology of the nanocomposites was evaluated with X‐ray diffraction (XRD) and transmission electron microscopy (TEM). Properties, such as the mechanical, thermal, and electrical properties, and the dynamic thermal stability against dehydrochlorination were also evaluated. Nanocomposites with a hybrid intercalated/exfoliated structure were obtained in all of the situations considered, as demonstrated by the XRD and TEM results and indirectly by the increment of Young's modulus of the formulations with increasing amount of O‐MMT incorporated. The modeling of Young's modulus by the Halpin–Tsai, Hui–Shia, and Lewis–Nielsen theories showed that the process of nanocomposite preparation allowed the aspect ratio of the clay particles to increase; these values were comparable to those nanocomposites obtained by other researchers with different polymeric matrices and methodologies. © 2009 Wiley Periodicals, Inc.

Synthesis of graft copolymers based on polyphenylene xylylene and fullerene grafted polystyrene
Authors: Wootthikanokkhan J. , Thanachayanont C. , Seeponkai N. 
Published: December 2009

AbstractGraft copolymers containing poly(phenylene xylyene) (PPX) backbone and polystyrene fullerene (PSFu) grafting chains (PPX‐g‐PSFu) were prepared by using a purposed synthetic route comprising a combination of reaction mechanisms namely the modified Wessling route, an iniferter polymerization, and an atom transfer radical addition (ATRA). The monomer was first prepared by reacting dichloroxylene with tetrahydrothiophene. After that the monomer was polymerized in a sodium hydroxide solution to provide a polymer precursor. Subsequently, the polymer precursor was modified by reacting it with a dithiocarbamate (DTC) compound. The macroiniferter was obtained and then copolymerized with styrene and chloromethylstyrene via an iniferter polymerization. Finally, the graft copolymer was reacted with fullerene through an ATRA technique to attach the C60 groups onto the graft copolymer molecule. The products obtained from each of the steps were characterized by using various techniques including Fourier transform infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, gel permeation chromatography, differential scanning calorimetry, UV–visible spectroscopy, and thermal gravimetric analysis. The aforementioned results suggest that the graft copolymers were prepared. The grafting yield and grafting efficiency were found to increase with the monomers concentration and the amount of DTC used. Some homopolymer contaminants also occurred but those could be minimized and subsequently removed by extraction with selective solvents. These graft copolymer products might be used for the development of a bulk heterojunction polymer solar cell. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Solvothermal process for grafting dibutylmaleate onto poly(ethylene‐co‐1‐octene)
Authors: Yu Juan , Qi Rongrong , Liu Qiaochu 
Published: December 2009

AbstractSolvothermal process was successfully developed to graft dibutylmaleate (DBM) onto poly(ethylene‐co‐1‐octene) (POE) with dicumyl peroxide (DCP) as free radical‐initiator. FTIR spectra demonstrate that DBM is successfully grafted onto the backbone of POE by this novel method. The influences of DBM content, DCP concentration, POE concentration, reaction temperature and reaction time on the grafting copolymerization have been investigated in detail through grafting degree (GD). It is worthy to indicate that high grafting degree (above 15%) can be achieved through the one‐pot way when the graft reaction is carried out in 40 mL toluene at 150°C for 5 h with 1.6 g DBM, 6–8 g POE and 0.35 g DCP. This developed solvothermal process is becoming an effective way to prepare POE‐g‐DBM graft copolymers, and can be extended to other systems. In addition, TGA results show that the thermal properties of POE are enhanced after the grafting reaction. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
