Authors: Trisnawati Ema , Afifah Nur , Mustaruddin  , Cahyani Rinta 
Published: June 2024

Aims: The aim of this study is to investigate the impact of sensing capability, learning capability, and coordinating capability on the market performance of Small and Medium Enterprises (SMEs). By examining these three critical capabilities, this research seeks to provide a comprehensive understanding of how SMEs can leverage their internal resources and competencies to achieve superior market outcomes as a market performance in today's dynamic and competitive business environment.
Study Design: This study employs a quantitative research approach using a cross-sectional survey design to gather data on SMEs' sensing, learning, and coordinating capabilities, as well as their market performance.
Place and Duration of Study: The study was conducted in Pontianak, West Kalimantan, Indonesia. Data were collected from 97 SME owners or managers who were selected based on the criteria of having been established for at least 3 years.
Methodology: Data collection was done using a structured questionnaire administered through an online survey platform. The collected data were analyzed using Structural Equation Modeling (SEM) with the Partial Least Squares (PLS) approach. The analysis was conducted using SmartPLS 4.0 software and involved two stages: (1) measurement model assessment and (2) structural model assessment.
Results: The analysis results confirm the convergent validity, internal consistency, composite reliability, and discriminant validity of the constructs: Sensing Capability (SC), Learning Capability (LC), Coordinating Capability (CC), and Market Performance (MP). Using SEM with SmartPLS V.4, the study found that sensing capability (β = 0.383, p < 0.05) and learning capability (β = 0.430, p < 0.05) significantly impact market performance, supporting hypotheses H1 and H2. However, H3 was not supported, as coordinating capability (β = 0.088, p > 0.05) did not show a significant relationship with market performance.
Conclusion: This study emphasizes the importance of sensing and learning capabilities for SMEs in Pontianak to enhance market performance. Coordinating capability may have an indirect effect. SME owners and managers should invest in these capabilities to adapt to market changes and maintain a competitive advantage. The findings contribute to the understanding of dynamic capabilities and provide practical insights for SMEs in West Kalimantan, Indonesia.
Decentralized adaptive backstepping stabilization of interconnected systems with input time delays in dynamic interactions
Authors: Zhou Jing 
Published: October 2011

SUMMARYIn this paper, we provide a solution to the problem by considering input time delays in dynamic interactions. Each local controller, designed simply on the basis of the model of each subsystem by using filtered transformation and standard backstepping technique, only employs local information to generate control signals. The robustness of decentralized adaptive controllers is established. It is shown that the designed decentralized adaptive backstepping controllers can globally stabilize the overall interconnected system asymptotically. The L2 and L∞ norms of the system outputs are also established as functions of design parameters. This implies that the transient system performance can be adjusted by choosing suitable design parameters. Copyright © 2011 John Wiley & Sons, Ltd.
Hybrid Foams – A New Approach for Multifunctional Applications
Authors: Reinfried Matthias , Stephani Günter , Luthardt Fabian , Adler Jörg , John Marianne , Krombholz Andreas 
Published: October 2011

AbstractHybrid foams consist of two different interpenetrating or particulate‐embedded foam‐material classes and, therefore, an enhanced multifunctionality of the material and of the final product can be expected. This paper illustrates the concept of hybrid foams with two selected examples. The cells of an open‐cell steel host‐foam are filled either with a polymer foam or a newly developed direct ceramic foam.The results of compression tests and non‐destructive resonance‐frequency‐damping analyses are presented. An improvement in the deformation is observed for the metal‐polymer hybrid foam, while the deformation behavior changes from brittle to ductile for the metal‐ceramic hybrid foams. Additionally, the damping and Young's modulus of the metal foam are enhanced by the interpenetrating direct foamed ceramic.

AbstractImmune thrombocytopenia (ITP) is characterized by platelet clearance mediated primarily by autoantibodies against the platelet GPIIbIIIa and/or GPIbα. Steroid therapy is a first‐line treatment for ITP. However, some patients are refractory to this therapy and currently no method can predict which patients will respond. To evaluate whether steroids are equally efficacious in treating patients with ITP caused by anti‐GPIIbIIIa versus anti‐GPIbα antibodies, we performed a retrospective study on 176 newly diagnosed patients with acute ITP who had severe bleeding symptoms and were admitted as resident patients to the hospital. The patients were treated first with intravenous administration of high‐dose dexamethasone (DXM), followed by oral administration of prednisone. Response to therapy was observed in a majority of patients with antibodies specific for GPIIbIIIa (31/43) or without detectable antibodies against either GPIIbIIIa or GPIbα (36/45). In contrast, the steroid response was significantly lower in patients with anti‐GPIbα antibodies (9/34) or with antibodies against both GPIbα and GPIIbIIIa (16/54). The preliminary findings of this study suggest that in future prospective clinical trials including corticosteroids, the anti‐GPIbα, and ‐GPIIbIIIa status should be assessed in order to test its potential relevance in deciding future treatments. © Wiley Periodicals, Inc.
Whole‐exome sequencing detects somatic mutations of IDH1 in metaphyseal chondromatosis with D‐2‐hydroxyglutaric aciduria (MC‐HGA)

AbstractWe used exome sequencing of blood DNA in four unrelated patients to identify the genetic basis of metaphyseal chondromatosis with urinary excretion of D‐2‐hydroxy‐glutaric acid (MC‐HGA), a rare entity comprising severe chondrodysplasia, organic aciduria, and variable cerebral involvement. No evidence for recessive mutations was found; instead, two patients showed mutations in IDH1 predicting p.R132H and p.R132S as apparent somatic mosaicism. Sanger sequencing confirmed the presence of the mutation in blood DNA in one patient, and in blood and saliva (but not in fibroblast) DNA in the other patient. Mutations at codon 132 of IDH1 change the enzymatic specificity of the cytoplasmic isocitrate dehydrogenase enzyme. They result in increased D‐2‐hydroxy‐glutarate production, α‐ketoglutarate depletion, activation of HIF‐1α (a key regulator of chondrocyte proliferation at the growth plate), and reduction of N‐acetyl‐aspartyl‐glutamate level in glial cells. Thus, somatic mutations in IDH1 may explain all features of MC‐HGA, including sporadic occurrence, metaphyseal disorganization, and chondromatosis, urinary excretion of D‐2‐hydroxy‐glutaric acid, and reduced cerebral myelinization. © 2011 Wiley Periodicals, Inc.

Authors: Zhang Hui‐Juan , Zhang Zhao‐Zhu , Guo Fang 
Published: October 2011

AbstractModification of composites was a general method to improve their tribological behaviors. On the way to explore composites with enhanced tribological behaviors, we have successfully prepared hybrid PTFE/Nomex fabric/phenolic composite filled with multiwalled carbon nanotubes (MWCNTs) or MWCNTs modified by polystyrene (PS) with a grafting to method. The results of pin‐on‐disc type wear tests indicated tribological behaviors were improved both for hybrid PTFE/Nomex fabric/phenolic composite filled with MWCNTs and MWCNTs‐PS, especially for that of filled with MWCNTs‐PS. And the probable reason was also discussed based on the characterization results. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

Published: October 2011

AbstractUrea–formaldehyde (UF) resin microcapsules doped with TiO2 nanoparticles were prepared by in situ polymerization, and the properties of the microcapsules, such as the surface morphologies, thermal properties, and chemical elemental composition, were measured by optical microscopy, scanning electron microscopy, thermogravimetric analysis, and energy‐dispersive X‐ray spectrometer analysis. The effects of the presence of ammonium chloride and its concentration and the concentrations of UF resin prepolymer and TiO2 nanoparticles during the reaction and deposition of UF on the microcapsule surface on the properties of the microcapsules were investigated. Enhanced UF resin microcapsules with more stability and mechanical strength could be obtained under the optimal conditions. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
Simulation of a flexible polymer tethered to a flat adsorbing surface
Authors: Li Hong , Qian Chang‐Ji , Luo Meng‐Bo 
Published: October 2011

AbstractA lattice self‐avoiding polymer chain with one end attached to an adsorbing flat surface is simulated using Monte Carlo method. The chain model has z = 26 bond vectors with bond length being 1,
$\sqrt 2$, and
$\sqrt 3$
on the simple cubic lattice. The dependence of the number of surface contacts M on temperature T in the unit E/kB with E the interacting energy and kB the Boltzmann constant and chain length N is investigated by a finite‐size scaling law M = Nϕ(a0 + a1(T − Tc)N1/δ + O((T − Tc)2N2/δ)) near the critical adsorption point Tc. It was estimated that Tc = 1.625 and the exponents ϕ = 0.52 and δ = 1.63. It was observed that both mean square end‐to‐end distance 〈R2〉 and mean square radius of gyration 〈R〉 reach minimum at Tc. And we discover that the asphericity parameter 〈A〉 is independent of chain length at Tc. A simple relationship is discovered between Tc and bond vector number nb for lattice chain models, and which can be extended to nonlattice chain models by introducing an attraction range fraction f. © 2011 Wiley Periodicals, Inc.

Dramatic influence of curing temperature on micro–nano structure transform of HNBR filled with zinc dimethacrylate
Authors: Wei Zheng , Lu Yonglai , Yan Shouke , Meng Yang , Zhang Liqun 
Published: October 2011

AbstractThe influence of the curing temperature on micro‐nano structure transform of hydrogenated nitrile‐butadiene rubber (HNBR) reinforced by zinc dimethacrylate (ZDMA) through in situ polymerization was studied by means of Scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and X‐ray diffraction. The results showed that both the amount and diameter of the poly‐ZDMA aggregates increased and the graft ratio of poly‐ZDMA decreased with the increase of curing temperature. Meanwhile, with the increase of curing temperature, the maximum torque of the curing curve, the crosslinking density (especially for the ionic crosslinking density), and the mechanical properties of HNBR/ZDMA composite decreased significantly. We put forward a possible mechanism that can well explain the phenomenon observed in this work. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
Fabrication of honeycomb polyvinyl butyral film under humidity provided by super saturated salt solutions
Authors: Zhang Ruimin , Wang Jinwei , Wang Minjia , He Yedong 
Published: October 2011

AbstractWe introduce a novel method for making breath figure arrays (BFAs) on polyvinyl butyral (PVB) films under humidity by putting the dip coated samples inside a chamber filled with supersaturated salt solutions. With the increase in humidity or retention time, multiple porous films with bigger pore sizes and wider size distributions are generally obtained, resulting from the coalescence of the following‐up water drops. The presence of nitrogen flow accelerates the evaporation of solvents and vapor, thus increases the elastic interaction among water droplets such that films with smaller pores can be obtained. Compared to PVB/ethyl acetate solution, it is easier to obtain a film with regular honeycomb pattern by using PVB/chloroform solution. Its lower boiling point makes it evaporate faster to increase temperature gradient between film surface and the atmosphere; while its higher density makes it provide stronger support to maintain the shape of water droplets. In this study, the solubility of polymer in solvents is initially proposed to explain the BFAs formation. Higher mobility of polymer chains in a good solvent increases chances of its polar groups to interact with water droplets, thus increases the possibility of regular arrangements of water droplets on the film. © 2011 Wiley Periodicals, Inc.

Published: October 2011

AbstractIn this study, a new type of polypropylene (PP)/polyester (PET) bicomponent melt‐blown (bi‐MB) for filtration was developed through the melt‐blowing process with raw materials of melt‐blown (MB)‐grade PP and PET chips. The structure, porosity, and filtration performance of the bi‐MBs were tested through relevant instruments. The results show that the average fiber diameter in the bi‐MBs was 2–3.5 μm, the average pore size was 12.3–15.6 μm, and the porosity was 90–94%. The results also show that the filtration efficiency of the bi‐MBs was much higher than that of monocomponent PP MBs. It reached the highest value of 97.34% when the PP/PET ratio was 50/50 and could be used as high‐performance filter media. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
Polyethylene composite fibers. I. Composite fibers of high‐density polyethylene
Authors: Rattanawijan Waraporn , Amornsakchai Taweechai 
Published: October 2011

AbstractPolymer matrix composites are generally studied in the form of bulk solids, and very few works have examined composite fibers. The research described here extended such bulk studies to fibers. The question is whether or not what has been reported for bulk polymers will be the same in fibers. In this article are reported studies of high‐density polyethylene (HDPE), whereas those of linear low‐density polyethylene are reported in part II of this article series. Two types of filler were used, that is, organically modified montmorillonite (OMMT), in which the nanosized filler particles had a high aspect ratio, and microsized calcium carbonate (CaCO3), with an aspect ratio nearer to unity. Composite fibers of both as‐spun and highly drawn forms were prepared, and their structures, morphology, and mechanical properties were studied. It was found that the microsized particles gave HDPE composite fibers with mechanical properties that were the same as those of the neat polymer. In the case of clay composite fibers, the clay interfered with the yield process, and the usual yield point could not be observed. The particle shape did not affect the mechanical properties. The fibers showed different deformation morphologies at low draw ratios. The CaCO3 composite fibers showed cavities, which were indicative of low interaction between the polymer and the filler. The OMMT composite fibers showed platelets aligned along the fibers and good polymer–filler interaction. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

Published: October 2011

AbstractInherently conducting polymers (ICP) have attracted the attention of researchers because of their low cost and environmental stability. However, for commercial applications the poor processibility and solubility of ICPs have inhibited their widespread use. To avoid these disadvantages adducts, blends, and composites of conducting polymers have been developed. With a view to enhance the processibility of polyaniline (PANI), this work reports the synthesis of nano PANI polydihydroxydimethylsiloxane (PDMS) adduct and the formulation of its nanocomposite via the dispersion of this nano adduct in butylated melamine formaldehyde (BMF) cured soy alkyd (SA) in different weight loadings (0.25 wt %, 0.5 wt %, 1 wt %). The formation of PANI‐PDMS adduct and its dispersion in butylated melamine formaldehyde (BMF) cured soy alkyd (SA) was confirmed by FTIR, UV‐visible, 1H‐NMR whereas the morphological characterization was done using TEM and X‐ray diffraction analyses. The presence of PANI‐PDMS in SA‐BMF resin was found to significantly enhance the physicochemical, physicomechanical, and thermal properties which could be utilized in the development of corrosion protective paints and coatings. © 2011 Wiley Periodicals, Inc.

Novel aromatic and aromatic–aliphatic poly(thiourea‐amide)s for the extraction of toxic heavy metal ions
Authors: Kausar Ayesha , Zulfiqar Sonia , Ahmad Zahoor , Ishaq Muhammad , Ilyas Sarwar Muhammad 
Published: October 2011

AbstractA series of novel aromatic and aromatic–aliphatic diamines [isophthaloyl bis(3‐(3‐aminophenyl)thiourea), terephthaloyl bis(3‐(3‐aminophenyl)thiourea), adipoyl bis(3‐(3‐aminophenyl)thiourea), sebacoyl bis(3‐(3‐aminophenyl)thiourea)] were synthesized starting from the dinitro compounds. Spectroscopic and elemental analyses were carried out for the structure elucidation of the monomers. Three series of poly(thiourea‐amide)s (PTAMs) bearing CS groups were prepared through the condensation of new diamines with the diacid chlorides such as isophthaloyl, terephthaloyl and adipoyl chloride. The ensuing PTAMs were characterized using FTIR, 1H‐NMR and 13C‐NMR techniques. Physical properties of the polymers such as solution miscibility, crystallinity, solution viscosity, molecular weight, and thermal properties were measured. Consequently, good organosolubility of these polymers was experiential in amide solvents as DMAc, DMF, DMSO and NMP. Moreover, PTAMs exhibited ηinh in the range of 0.92–1.56 dL/g and GPC measurements revealed Mw around 607 × 102‐851 × 102. DSC served to envisage the glass transition temperatures (Tg) of poly(thiourea‐amide)s located between 232 and 258°C and the initial decomposition temperatures (T0) probed by thermogravimetry were in the range of 305–419°C. Structure‐property relationship of these polymers was also studied. Eventually, solid−liquid extraction tests of the selected poly(thiourea‐amide)s systems revealed excellent results because these polymers show nearly 100% elimination of lead and mercury cations from water media. © 2011 Wiley Periodicals, Inc.

Herschel‐Bulkley rheological parameters of a novel environmentally friendly lightweight biopolymer drilling fluid from xanthan gum and starch
Authors: Khalil Munawar , Mohamed Jan Badrul 
Published: October 2011

AbstractThis article summarizes a concise investigation on the effect of concentration of the four main components of a novel lightweight drilling fluid, i.e., glass bubbles, xanthan gum, starch, and clay, to the Herschel‐Bulkley rheological model parameters. The three parameters of Herschel‐Bulkley model, i.e., yield stress, fluid consistency, and fluid index were calculated by fitting the experimental data of shear stress as a function of rate of shear to the model. Results indicate that the increment of the amount of four main components increase the yield stress of the final fluid as the flow resistance is increased. Furthermore, the result also showed that the calculated fluid consistency of the drilling fluid appears to be strongly dependent on the presence of glass bubbles, xanthan gum, and clay. However, the fluid consistency appears not to be affected by the presence of starch. It is also concluded that the presence of glass bubbles, xanthan gum, and clay in the fluid tends to determine the final fluid to behave as pseudoplastic. © 2011 Wiley Periodicals, Inc.

Published: October 2011

AbstractIn this study, compatibilizing ability of silicone carbide modified multiwalled carbon nanotube (MWCNT) and polyphosphazene for the incompatible polyetherimide/liquid crystalline polymer (LCP) blend was investigated in detail. From rheological study, it was evident that the viscosities of binary and ternary blends were lower than those of the neat polymers, which signifying the great ability of LCP as a processing aid. Field emission scanning electron microscopic analysis revealed that the addition of polyphosphazene and modified MWCNT, together, reduced the average domain size of LCP and improved the filler‐matrix adhesion. Measurement of surface energy from contact angle measurement also point towards the improved interfacial interaction, in presence of compatibilizers. © 2011 Wiley Periodicals, Inc.

Authors: Sahoo B. P. , Naskar K. , Choudhary R. N. P. , Sabharwal S. , Tripathy D. K. 
Published: October 2011

AbstractThe dielectric relaxation characteristics of conductive carbon black (CCB) reinforced ethylene acrylic elastomer (AEM) vulcanizates have been studied as a function of frequency (101–106 Hz) at different filler loading over a wide range of temperatures (30–120°C). The effect of filler loadings on the dielectric permittivity (ε′), loss tangent (tan δ), complex impedance (Z*), and electrical conductivity (σac) were studied. The variation of ε′ with filler loading has been explained based on the interfacial polarization of the fillers within a heterogeneous system. The effect of filler loading on the imaginary (Z″) and real (Z′) part of Z* were distinctly visible, which may be due to the relaxation dynamics of polymer chains at the polymer–filler interface. The frequency dependency of σac has been investigated using percolation theory. The phenomenon of percolation in the composites has been discussed in terms of σac. The percolation threshold (ϕcrit) occurred in the range of 20–30 phr (parts per hundred) of filler loading. The effect of temperature on tan δ, ε′, σac, and Nyquist plots of CCB‐based AEM vulcanizates has been investigated. The CCB was uniformly dispersed within the AEM matrix as studied from the transmission electron microscope (TEM) photomicrographs. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
