Perception parentale du soutien social postnatal
Authors: Capponi Irène
Published: March 2013

Afin d’examiner la perception que les mères et pères ont de leur soutien social respectif, un questionnaire a été soumis à 72 couples un mois et trois mois après la naissance. Cet article reprend une partie des données de l’étude. Une similitude du réseau social, tant en termes quantitatifs que qualitatifs, est observé chez les pères et mères. En outre, 27 % des couples sont très isolés dans la mesure où les deux partenaires ont un réseau réduit (moins de trois personnes, conjoint compris). Enfin, une faiblesse du soutien d’ordre émotionnel s’est révélée de façon manifeste aussi bien pour les mères que pour les pères. Ces résultats attirent l’attention sur la solitude paternelle lors de l’accès à la parentalité, à laquelle nous ne serions pas encore suffisamment sensibilisés.

Une étude canadienne récente (2011-2012) a permis d’explorer la concordance entre les besoins et les interventions de participation d’aînés en perte d’autonomie recevant des services d’aide à domicile. Les besoins non satisfaits concernent principalement les activités sociales (responsabilités, relations interpersonnelles, vie communautaire et loisirs) et certaines activités courantes (condition corporelle, habitation, déplacements). Plusieurs constats permettent d’expliquer cette non-concordance qui limite la participation et l’ empowerment des aînés fragilisés.

Awareness of ICT-Based Projects and the Intensity of Use of Mobile Phones Among Smallholder Farmers in Uganda
Authors: Lwasa Stephen , Asingwire Narathius , Okello Julius Juma , Kiwanuka Joseph
Published: March 2013

As the use of information and communication technologies (ICT) is embraced in Uganda, determinants of awareness of ICT based projects remain unknown. The intensity of use of mobile phones among smallholder farmers in the areas where such projects operate is unclear. To address this knowledge gap, 346 smallholder farmers in two ICT project sites in Mayuge and Apac districts were subjected to econometric analysis using bi-variate logistic and zero-inflated negative binomial regression models to ascertain determinants of projects’ awareness and intensity of use of mobile phones. The authors find that education, distance to input markets, and membership in a group positively influence awareness. The decision to use a mobile phone for agricultural purposes is affected by distance to electricity and land cultivated and negatively influenced by being a member of any farmer group. Lastly, intensity of mobile phone use is affected by age, farming as the major occupation, and distance to an internet facility, being a member of a project, having participated in an agricultural project before, value of assets, size of land cultivated, possession of a mobile phone, and proximity to agricultural offices. The paper discusses policy implications of these findings.

Authors: Bwalya Kelvin Joseph , Chris Rensleigh , Mandla Ndlovu
Published: March 2013

The convergence of wireless applications presents a greater hope for consolidating e-Government (ICT-enabled or online government) applications even in resource-constrained countries such as those in Africa. This chapter presents an exploratory study that aims at discussing the extent as to how convergence of wireless technologies from different vendors promises to contribute to the consolidation of e-Government applications in Sub-Saharan-Africa (SSA). This is done by reviewing the different adoption stages of ICT and e-Government in SSA. It looks at challenges facing adoption of wireless technologies (GSMs, Wireless Internet Access, satellite transmission, etc.) across all the socio-economic value chains in SSA. The chapter looks at Botswana and South Africa as case studies by bringing out the different interventions that have been done in the realm of facilitating a conducive environment for the convergence of different wireless technologies. Out of the analysis of legal, regulatory, market and spectrum policies affecting the adoption of wireless communications in SSAs, the chapter draws out recommendations on how to consolidate wireless communications to be adopted in different socio-economic setups (e.g. e-government, e-Health, e-Banking, etc.).
Gender and National Information and Communication Technology (ICT) Policies in Africa
Authors: Igun Stella E.
Published: March 2013

This chapter discusses the importance of incorporating gender aspects into the national ICT policies in Africa. The mention of gender issues in national ICT policies in Africa is still very scanty (where they exist). Many countries in Africa have no clear gender aspects incorporated into their national ICT policies. The chapter focuses on the imperativeness of ICTs to the livelihood of women in Africa, the need and urgency of increasing and encouraging women participation in all aspects of ICTs. The enactment and implementation of ICT policies and strategies targeting women population in both rural and urban areas is inevitable. Thus, status of gender inequality of ICT in Africa, strategies geared towards addressing gender inequalities in ICT in Africa and gender and ICT perspectives were discussed.

Dementia is, unfortunately, a well-known problem and a product of a set of generational transformations as a result of better life conditions. Since we cannot eradicate this problem, we can try to develop means to minimize the effects. Alzheimer disease is one type of dementia that affects 7.3 million people in Europe. Alzheimer does not only affect the person who is ill but also their families and friends at different levels, such as personal, emotional, social, and financial. In this chapter, the authors present an interactive application that, based on a narrative retrospective of the patient’s life, tries to fight the evolution of the disease and maximize the patient’s cognitive function. With this, the authors aim to minimize the effects of the illness and improve the life not only of the patient but also of his/her caregivers and family.
A Semantic Web Pragmatic Approach to Develop Clinical Ontologies, and thus Semantic Interoperability, based in HL7 v2.xml Messaging
Authors: Mendes David , Rodrigues Irene Pimenta
Published: March 2013

The ISO/HL7 27931:2009 standard intends to establish a global interoperability framework for healthcare applications. However, being a messaging related protocol, it lacks a semantic foundation for interoperability at a machine treatable level intended through the Semantic Web. There is no alignment between the HL7 V2.xml message payloads and a meaning service like a suitable ontology. Careful application of Semantic Web tools and concepts can ease the path to the fundamental concept of Shared Semantics. In this chapter, the Semantic Web and Artificial Intelligence tools and techniques that allow aligned ontology population are presented and their applicability discussed. The authors present the coverage of HL7 RIM inadequacy for ontology mapping and how to circumvent it, NLP techniques for semi-automated ontology population, and the current trends about knowledge representation and reasoning that concur to the proposed achievement.
Molecular Visualization with Supports of Interaction, Immersion, and Collaboration among Geographically Separated Research Groups
Authors: Francischetti-Corrêa Moacyr
Published: March 2013

In the search for new drug and medication discovery, especially related to drug-receptor interaction, the importance of interaction among researchers is essential, either within the same room or dispersed throughout the world. The interaction in an online environment through the molecule shared view and information and ideas exchange via text and/or voice enable researchers to discuss molecule aspects under study, increasing the chances of reaching the new compound’s identification. In subsequent sections an architecture that uses concepts of Distributed Multiuser Virtual Reality, Computer-Supported Collaborative Work, and world-wide network communication techniques for creating a high performance system that allows real-time interaction among various geographically dispersed research groups studying molecular visualization and using hardware systems ranging from desktop to immersive systems as CAVEs is presented. Its construction was made possible by defining a structure based on local servers to each group, which communicate with each other on a remote network, and creating a protocol for communication among these servers that seeks agility to minimize the negative effects of packet loss and delay delivery, Internet characteristic problems.

During experimental sepsis, excessive generation of the anaphylatoxin C5a results in reduction of the C5a receptor (C5aR) on neutrophils. These events have been shown to result in impaired innate immunity. However, the regulation and fate of C5aR on neutrophils during sepsis are largely unknown. In contrast to 30 healthy volunteers, 60 patients in septic shock presented evidence of complement activation with significantly increased serum levels of C3a, C5a, and C5b-9. In the septic shock group, the corresponding decrease in complement hemolytic activity distinguished survivors from nonsurvivors. Neutrophils from patients in septic shock exhibited decreased C5aR expression, which inversely correlated with serum concentrations of C-reactive protein (CRP) and clinical outcome. In vitro exposure of normal neutrophils to native pentameric CRP led to a dose- and time-dependent loss of C5aR expression on neutrophils, whereas the monomeric form of CRP, as well as various other inflammatory mediators, failed to significantly alter C5aR levels on neutrophils. A circulating form of C5aR (cC5aR) was detected in serum by immunoblotting and a flow-based capture assay, suggestive of an intact C5aR molecule. Levels of cC5aR were significantly enhanced during septic shock, with serum levels directly correlating with lethality. The data suggest that septic shock in humans is associated with extensive complement activation, CRP-dependent loss of C5aR on neutrophils, and appearance of cC5aR in serum, which correlated with a poor outcome. Therefore, cC5aR may represent a new sepsis marker to be considered in tailoring individualized immune-modulating therapy.

Plasmacytoid dendritic cells (pDC) are the major producers of type I IFN during the initial immune response to viral infection. Ly49Q, a C-type lectin-like receptor specific for MHC-I, possesses a cytoplasmic ITIM and is highly expressed on murine pDC. Using Ly49Q-deficient mice, we show that, regardless of strain background, this receptor is required for maximum IFN-α production by pDC. Furthermore, Ly49Q expression on pDC, but not myeloid dendritic cells, is necessary for optimal IL-12 secretion, MHC-II expression, activation of CD4+ T cell proliferation, and nuclear translocation of the master IFN-α regulator IFN regulatory factor 7 in response to TLR9 agonists. In contrast, the absence of Ly49Q did not affect plasmacytoid dendritic cell–triggering receptor expressed on myeloid cells expression or pDC viability. Genetic complementation revealed that IFN-α production by pDC is dependent on an intact tyrosine residue in the Ly49Q cytoplasmic ITIM. However, pharmacological inhibitors and phosphatase-deficient mice indicate that Src homology 2 domain-containing phosphatase 1 (SHP)-1, SHP-2, and SHIP phosphatase activity is dispensable for this function. Finally, we observed that Ly49Q itself is downregulated on pDC in response to CpG exposure in an ITIM-independent manner. In conclusion, Ly49Q enhances TLR9-mediated signaling events, leading to IFN regulatory factor 7 nuclear translocation and expression of IFN-I genes in an ITIM-dependent manner that can proceed without the involvement of SHP-1, SHP-2, and SHIP.

Extracellular nucleotides have been recognized as important modulators of inflammation via their action on specific pyrimidine receptors (P2). This regulation coexists with the temporal framework of proinflammatory and proresolution mediators released by the cells involved in the inflammatory response, including macrophages. Under proinflammatory conditions, the expression of cyclooxygenase-2 leads to the release of large amounts of PGs, such as PGE2, that exert their effects through EP receptors and other intracellular targets. The effect of these PGs on P2 receptors expressed in murine and human macrophages was investigated. In thioglycollate-elicited and alternatively activated macrophages, PGE2 selectively impairs P2Y but not P2X7 Ca2+ mobilization. This effect is absent in LPS-activated cells and is specific for PGE2 because it cannot be reproduced by other PGs with cyclopentenone structure. The inhibition of P2Y responses by PGE2 involves the activation of nPKCs (PKCε) and PKD that can be abrogated by selective inhibitors or by expression of dominant-negative forms of PKD. The inhibition of P2Y signaling by PGE2 has an impact on the cell migration elicited by P2Y agonists in thioglycollate-elicited and alternatively activated macrophages, which provide new clues to understand the resolution phase of inflammation, when accumulation of PGE2, anti-inflammatory and proresolving mediators occurs.
Pitfalls in �Biblical� leadership
Authors: Kessler Volker
Published: March 2013

This article is about the pitfalls involved in writing a Christian handbook on leadership. By analysing some elements of the Rule of Benedict it is argued that it is impossible to write such a handbook without using non-Biblical sources. Moreover, there are typical pitfalls when authors attempt to develop a pure Biblical leadership theory. The first pitfall is typical of Christians representing Niebuhr�s type of �Christ against Culture�. As early as 1951, Niebuhr claimed that in the field of leadership in particular the radical exclusive Christians reintroduced rules from non-Christian cultures. Examples from the last decade support Niebuhr�s observation. The second pitfall, referred to as reconstruction, is typical of those authors who are open to secular sources but who seek to give Biblical evidence for their leadership theory. This pitfall is illustrated by analysing the process in which the secular concepts of transforming leadership and vision statements found their way into evangelical books on Christian leadership. Reconstruction typically consists of four steps: Perception (a secular model of leadership becomes popular), Acceptance (this model is examined and accepted for the context of the church) Assimilation (it is claimed that leaders in the Bible worked exactly as described in the model, books are written about Biblical leadership, exemplifying the model. The secular source becomes obsolete.) and Standardisation (this model of leadership is declared to be the Biblical norm for every Christian leader). I argue that step 3 is at least problematic and step 4 is a fatal error.
A Further Study of the Role of Copper in Regard to the Antimutagenic Action of Sodium Copper Chlorophyllin (SCC) in Somatic Cells of Drosophila melanogaster
Authors: Pimentel Emilio , Cruces Martha P. , Zimmering Stanley
Published: March 2013

Previous findings suggest that copper plays a crucial role in the antimutagenic effect of sodium copper chlorophyllin (SCC). The objective of the current research was to compare the antimutagenic effects of two SCC compounds with different amounts of copper (3.7% and 5.4%, respectively) on the genetic damage induced by gamma rays in somatic cells of Drosophila. Data indicate that an increase in copper content of 31.5% in SCC-5.4 resulted in a greater inhibition of gamma ray genetic damage of 49% whereas only a 2% inhibition with SCC-3.7 occurred. Of greater interest is the association of SCC with a variety of uses in humans, such as a chemo preventive agent and food supplement. A greater attention to the concentration of copper in the SCC product in use should be required.

Identifying biomarkers that distinguish Parkinson's disease (PD) from normal control (NC) individuals has the potential to increase diagnostic sensitivity for the detection of early-stage PD. A previous proteomic study identified potential biomarkers in postmortem ventricular cerebrospinal fluid (V-CSF) from neuropathologically diagnosed PD subjects lacking Alzheimer's disease (AD) neuropathology. In the present study, we assessed these biomarkers as well as p-tau181, Aβ42, and S100B by ELISA in PD (n = 43) and NC (n = 49) cases. The p-tau181/Aβ42 ratio and ApoA-1 showed statistically significant differences between groups. Multiple regression analysis demonstrated that p-tau181/Aβ42 had a significant odds ratio: OR = 1.42 (95% confidence interval [CI], 1.12–1.84), P = 0.006. Among the molecules investigated, intriguing correlations were observed that require further investigation. Our results suggest coexistent AD CSF biomarkers within the PD group notwithstanding that it was selected to minimize AD neuropathological lesions.

The Benefits of Knitting for Personal and Social Wellbeing in Adulthood: Findings from an International Survey
Authors: Riley Jill , Corkhill Betsan , Morris Clare
Published: March 2013

Introduction:

There is increasing evidence that engaging in creative and meaningful occupation can impact positively on health and wellbeing. Much of the research in this area has concentrated on general occupational categories and less is known about the benefits of specific occupations. This study aimed to identify the benefits of knitting for individuals' personal and social wellbeing as a prerequisite to investigating its therapeutic use.

Method:

An online survey was conducted through an internet knitting site. Responses were received from 3,545 knitters worldwide. Quantitative data were analysed statistically to establish relationships and differences among variables and qualitative data for key themes.

Results:

Respondents came from a virtual community of knitters. The majority were female white adults and frequent knitters, who commonly reported knitting for relaxation, stress relief and creativity. The results show a significant relationship between knitting frequency and feeling calm and happy. More frequent knitters also reported higher cognitive functioning. Knitting in a group impacted significantly on perceived happiness, improved social contact and communication with others.

Conclusion:

Knitting has significant psychological and social benefits, which can contribute to wellbeing and quality of life. As a skilled and creative occupation, it has therapeutic potential — an area requiring further research.
NOx reduction is the main pathway for benthic N2O production in a eutrophic, monomictic south-alpine lake
Authors: Freymond C. V. , Wenk C. B. , Frame C. H. , Lehmann M. F.
Published: March 2013

Abstract. Nitrous oxide (N2O) is a potent greenhouse gas, generated through microbial nitrogen (N) turnover processes, such as nitrification, nitrifier denitrification, and denitrification. Previous studies quantifying natural sources have mainly focused on soils and the ocean, but the potential role of terrestrial water bodies in the global N2O budget has been widely neglected. Furthermore, the biogeochemical controls on the production rates and the microbial pathways that produce benthic N2O in lakes are essentially unknown. In this study, benthic N2O fluxes and the contributions of the microbial pathways that produce N2O were assessed using 15N label flow-through sediment incubations in the eutrophic, monomictic south basin of Lake Lugano in Switzerland. The sediments were a significant source of N2O throughout the year, with production rates ranging between 140 and 2605 nmol N2O h−1 m−2, and the highest observed rates coinciding with periods of water column stratification and stably anoxic conditions in the overlying bottom water. Nitrate (NO3–) reduction via denitrification was found to be the major N2O production pathway in the sediments under both oxygen-depleted and oxygen-replete conditions in the overlying water, while ammonium oxidation did not significantly contribute to the benthic N2O flux. A significant portion (up to 15%) of the total NO3– consumed by denitrification was reduced only to N2O, without complete denitrification to N2. These fluxes were highest when the bottom water had completely stabilized to a low-oxygen state, in contrast with the notion that stable anoxia is particularly conducive to complete denitrification without accumulation of N2O. This study provides evidence that lake sediments are a~significant source of N2O to the overlying water and may produce large N2O fluxes to the atmosphere during seasonal mixing events.
Regional and local patterns in depth to water table, hydrochemistry, and peat properties of bogs and their laggs in coastal British Columbia
Authors: Howie S. A. , van Meerveld H. J.
Published: March 2013

Abstract. In restoration planning for damaged raised bogs, the lagg at the bog margin is usually not given considerable weight and is sometimes disregarded entirely. However, the lagg is critical for the proper functioning of the restored bog, as it supports the water mound in the bog. In order to include the lagg in a restoration plan for a raised bog, it is necessary to understand the ecohydrological characteristics and functions of this transition zone. To this end, we studied 13 coastal British Columbia (BC) bogs and identified two different gradients in depth to water table, hydrochemistry, and peat properties: (1) a local bog expanse – bog margin gradient, and (2) a regional gradient related to climate and proximity to the ocean. Depth to water table generally increased across the transition from bog expanse to bog margin, but did not differ regionally. In the bog expanse, pH was above 4.2 in the Pacific Oceanic wetland region (cooler and wetter climate) and below 4.3 in the Pacific Temperate wetland region (warmer and drier climate). Both pH and pH-corrected electrical conductivity increased significantly across the transition from bog expanse to bog margin, though not in all cases. Sodium and magnesium concentrations were generally highest in exposed, oceanic bogs and lower in inland bogs. Ash content in peat samples increased across the bog expanse – bog margin transition, and appears to be a useful abiotic indicator of the location of the bog margin. These gradients highlight both local and regional diversity of bogs and their associated laggs. Knowledge of these gradients is critical if undisturbed bogs are used as templates for the restoration of damaged raised bogs.
Derivation of Boussinesq's shoaling law using a coupled BBM system
Authors: Kalisch H. , Senthilkumar A.
Published: March 2013

Abstract. This paper is focused on finding rules for waveheight change in a solitary wave as it runs up a slowly increasing bottom. A coupled BBM system is used to describe the solitary waves. Expressions for energy density and energy flux associated with the BBM system are derived, and the principle of energy conservation is used to develop an equation relating the waveheight and undisturbed depth to the initial undisturbed depth and the incident waveheight. In the limit of zero waveheight, Boussinesq's shoaling law is recovered.

O presente artigo apresenta uma análise da pesquisa na formação e no trabalho dos professores que atuam na educação básica pública no Estado de Goiás e no Distrito Federal. Utilizamos como perspectiva metodológica, o materialismo histórico-dialético, tendo como referência A discussão que trazemos é fruto da análise de dados de uma investigação já concluída, realizada no período de 2007 a 2009, sobre a concepção de pesquisa dos professores da educação básica que possuem formação stricto sensu e de uma outra investigação que encontra-se em andamento, iniciada em 2010 e que tem como objeto a formação e a atuação de pedagogas(os) em espaços escolares e não escolares. Os resultados apontam que os professores com formação stricto sensu vivem um processo de proletarização no trabalho e que desejam realizar pesquisas, mas não têm condições estruturais para desenvolvê-las, demandando a necessidade de se investir na carreira docente como uma política de profissionalização e valorização.
Small agricultural impoundments affect pollutant transport
Authors: Balcerak Ernie
Published: March 2013

Reservoirs created by dams intercept runoff from upslope areas and thus are often sinks for fertilizers and other pollutants that would otherwise flow downstream. Most studies of solute transport through impoundments have focused on large, long‐lived systems. However, small impoundments, such as those created for irrigation or livestock watering, are common in agricultural regions, and their total global surface area is comparable to that of large reservoirs. As these small systems mature, the impoundments fill with sediment, creating ecosystems with wetland‐like characteristics. Because dams that create these small impoundments are more likely to be degraded, poorly maintained, or removed by their owners, it is important to understand how changes in such systems may affect pollutant transport.

In this study, the immunological status of 61 patients with Fanconi anemia (FA) with advanced marrow failure before hematopoietic stem cell transplantation was analyzed by assessing the phenotype of peripheral blood lymphocytes, serum immunoglobulin (Ig) levels, and inflammatory cytokines. In patients with FA, total absolute lymphocytes (P < 0.0001), B cells (P < 0.0001), and NK cells (P = 0.003) were reduced when compared with normal controls. T cells (CD3), that is, cytotoxic T cells, naïve T cells, and regulatory T cells, showed a relative increase when compared with controls. Serum levels of IgG (P < 0.0001) and IgM (P = 0.004) were significantly lower, whereas IgA level was higher (P < 0.0001) than in normal controls. TGF‐β (P = 0.007) and interleukin (IL)‐6 (P = 0.0007) levels were increased in the serum of patients when compared with controls, whereas sCD40L level decreases (P < 0.0001). No differences were noted in the serum levels of IL‐1β, IL‐2, IL‐4, IL‐10, IL‐13, IL‐17, and IL‐23 between FA subjects and controls. This comprehensive immunological study shows that patients with FA with advanced marrow failure have an altered immune status. This is in accordance with some characteristics of FA such as the proinflammatory and proapoptotic status. In addition, B lymphocyte failure may make tight and early immunological monitoring advisable. Am. J. Hematol. 88:472–476, 2013. © 2013 Wiley Periodicals, Inc.
Multilayer films ageing under ultraviolet radiations: Complementary study by dielectric spectroscopy
Authors: Lewandowski Simon , Rejsek‐Riba Virginie , Bernès Alain , Perraud Sophie , Lacabanne Colette
Published: March 2013

The effect of ultraviolet (UV) irradiation on a multilayer film made of poly(ethylene terephthalate)/Polyamide 6/poly(ethylene terephthalate) was investigated by uniaxial tractions, UV‐visible‐NIR and Fourier transformed infra‐red‐attenuated total reflection spectroscopy, differential scanning calorimetry (DSC), and dynamic dielectric spectroscopy (DDS). The multilayer was exposed to ultraviolet radiations (filtered at 270 nm) for 7 days, in air. The complexity of the multilayer thermograms recorded by DSC and DDS has required the study of each film constituting the multilayer to assess each the contribution of each one of them. A deterioration in mechanical properties and a decrease in UV transmission for low wavelengths are observed. These evolutions seem to result to the photo‐oxidation of the poly(ethylene terephthalate) film mainly localized at the exposed layer. This layer acts as a UV protection filter for the other layers. However, the DDS analyses show a plasticization effect of the primary mode in the Polyamide 6, which is evidence of photo‐oxidation. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Tricolor electrochromism of PEDOT film electrodeposited in mixed solution of boron trifluoride diethyl etherate and tetrahydrofuran: Hypsochromic effect
Authors: Yi Cao , Yi‐Jie Tao , Hai‐Feng Cheng , Zhao‐Yang Zhang
Published: March 2013

PEDOT [poly (3,4‐ethyldioxythiophene)] films have been electrochemically prepared in mixed solution of boron trifluoride diethyl etherate and tetrahydrofuran (BFEE‐THF). The film shows tricolor electrochromism which is claret red at −0.8 V, light grey at 0.2 V, and sea blue at 1.0 V. The film retains 74% of the original electroactivity and unperturbed electrochromic behaviors after 3000 cycles indicating potential applications on EC devices. Spectroelectrochemistry indicates that the π‐π* transition absorption peak (λmax) in the neutral state is located at 512 nm and the calculated energy gap (Eg) is 1.76 eV by the onset wavelength. Compared to the electropolymerization of PEDOT films in conventional solvent, tricolor electrochromism can be ascribed both to the low onset oxidation potential and polymerization rate in BFEE‐THF, which may result in a low conjugation length of PEDOT. © 2013 Wiley Periodicals, Inc.

Authors: Lu Jiaqi , Qi Rongrong , Hu Xinli , Luo Yu , Jin Jieyu , Jiang Pingkai
Published: March 2013

To extend the applications of wood–plastic composites (WPCs), soft WPCs were prepared with ethylene vinyl acetate (EVA) and wood flour (WF) as major components via a two‐step process involving two‐roll mixing and compression molding. The effect of the various factors, such as WF, unsaturated fatty acid (UFA), and dicumyl peroxide contents, on the mechanical properties, processability, and morphology of the WPCs was investigated in detail. The addition of UFA could effectively improve the processability and flexibility of the composites. The in
situ grafting reaction between UFA and EVA considerably improved the adhesion of the WF and resin matrix. Consequently, soft WPCs with good performances in flexibility and processability were successfully obtained. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Published: March 2013

Vulcanization kinetics of constant viscosity natural rubber (CVNR) prepared with hydroxylamine hydrochloride was studied by using a Rheometer MDR2000. The results show that the first stage of curing period follows first‐order reaction, but the induction period and the end stage of curing period does not. The calculated reaction order n of the end stage of curing period of CVNR is in the range of 0.01–0.52, and that of natural rubber (NR) is in the range of 0.38–0.66. The reaction orders of the end stages of curing periods of CVNR and NR increase with increasing curing temperature, and the reaction order of the end stage of curing period of CVNR is smaller than that of NR at the same temperature. The rate constants of the induction period, the first stage of curing period and the end stage of curing period of CVNR are smaller than that of NR at the same temperature. The activation energies of the induction period, the first stage of curing period and the end stage of curing period of CVNR are greater than that of NR. The activation energy of the induction period of CVNR is increased by13.52%, the activation energy of the first stage curing period of CVNR is increased by 3.95%, and the activation energy of the end stage of curing period of CVNR is increased by 1.60% compared with the activation energies of NR. The time tdis of CVNR is longer than that of NR at the same temperature. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
A multivariant study of the absorption properties of poly(glutaric acid‐glycerol) films
Authors: Wyatt Victor T. , Yadav Madhav
Published: March 2013

Hydrogels and organogels are polymer networks that can absorb large amounts of water and organic solvent, respectively. In this study, solvent absorption into the matrices of poly(glutaric acid‐glycerol) hydrogel and organogel films amended with or without either iminodiacetic acid, sugarcane bagasse, pectin, corn fiber gum, or microcrystalline cellulose has been evaluated. Most of the starting materials used in this study, such as glycerol and the plant wall polysaccharides, are by‐products of biofuel production. Finding uses for them would further biofuel initiatives worldwide. To that end, experimental results showed that water absorption increased when using polymer films composed of additional glycerol or plant cell wall polysaccharides. The amount of solvent absorbed into the control film increased when incubated in pH 10 buffer solutions but decreased when incubated in pH 4 buffer solutions and NaCl solutions when compared with absorption of water. Incubating the polymers in solvent at elevated temperatures increased the absorption rate. It was determined that the combined effects of pKa and polarity can be used to predict solvent absorption. Dimethylsulfoxide (DMSO) could be selectively extracted from or desorbed into films from other solvents. Erosion of the polymer films in DMSO ranged from 1.9 (±0.2) to 34.7 (±3.4)%. In water, erosion ranged from 6.3 (±3.2) to 32.7 (±3.2)%. The polymer films resorbed 3.3‐ and 2.3‐fold more DMSO and water, respectively, when compared with the original amount of absorbed solvent. These materials are potentially good candidates for agricultural and medicinal applications because their ability to absorb, desorb, and erode can be tuned. © 2013 Wiley Periodicals, Inc. J. Appl.

Published: March 2013

The nanocomposite of PDMS using functionalized fumed silica and nonreactive POSS as fillers were prepared by blend method in a planetary mixer. Fumed silica was functionalized by aliphatic and aromatic groups to study the filler–filler interactions with the aliphatic and aromatic POSS fillers and consequently their influence on the properties in the PDMS matrix. Transmission electron microscope (TEM) showed a good dispersion in the systems having the silica and POSS fillers with similar modifications. However, aliphatic and aromatic filler combinations showed more aggregated structures. Moreover, aliphatic POSS despite of good dispersion at higher loadings, act as lubricant, which is attributed to the disturbance in the PDMS‐ silica filler interaction and also the filler–filler interaction within fumed silica. There is a decrease in complex viscosity with the functionalization of fumed silica and with the aromatic/aliphatic POSS fillers. The thermal stability of aromatic functionalized fillers improves owing to the thermally stable phenyl groups. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Bioinspired and biocompatible adhesive coatings using poly(acrylic acid)‐grafted dopamine
Authors: Duan Li Jie , Liu Ying , Kim Jiheung , Chung Dong June
Published: March 2013

Poly(acrylic acid) (PAA) was grafted with dopamine to increase its adhesion force to metal surface. Nitinol plate surfaces were then modified by coating with PAA‐g‐dopamine. To synthesize PAA‐g‐dopamine, PAA was first activated by dicyclohexylcarbodiimide and N‐hydroxysuccinimide (NHS) to form PAA–NHS. Dopamine was then copolymerized with PAA–NHS in an aqueous medium at pH 8.5. We propose to increase the adhesion of adhesive PAA‐g‐dopamine on nitinol to improve its durability. In this article, we studied wettability, surface elemental composition, and surface morphology. Biocompatibility was also assessed by L929 fibroblast cells in vitro. © 2013 Wiley Periodicals, Inc. J.

Blends of phthalic anhydride‐modified palm stearin alkyds with high carboxylic acid contents with epoxidized natural rubber
Authors: Khong Yoke Kum , Gan Seng Neon
Published: March 2013

Solution blends comprised of alkyd having high carboxylic acid (COOH) content and epoxidized natural rubber (ENR 50, having nominally 50% of the isoprene units converted to epoxide groups) are self‐crosslinkable at 30°C in toluene solution. Two modified palm stearin alkyds with different amounts of COOH groups were synthesized by reacting phthalic anhydride with alkyd containing excess hydroxyl (OH) groups under controlled conditions, leading to the formation of different amounts of COOH as side‐chains. The crosslinking reactions between the alkyds and ENR 50 in toluene solutions were investigated using FTIR and DSC. The compatibility between ENR 50 and alkyd was indicated by the presence of a single glass transition temperature (Tg) in the blend. Intercomponent crosslinking reactions have occurred between the epoxide groups of ENR 50 and COOH groups of alkyd with the formation of ester linkages. The crosslink density is proportional to the amount of COOH groups in the alkyd. As the COOH content is increased, the blend produces higher percentage of gel insoluble in toluene. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
