Published: May 2015

Abstract
A new series of novel nanostructured poly (aniline-co-m-aminobenzoic acid) copolymer has been synthesized by chemical oxidative in-situ polymerization method using dodecylbenzene sulphonic acid (DBSA) as a soft template. The synthesized copolymers were characterized by Fourier Transform Infrared spectroscopy, Ultraviolet visible spectroscopy, X-ray diffraction and scanning electron microscopy. The infrared spectrum shows the characteristic peaks confirming the formation of the copolymer. The ultraviolet visible spectrum shows the π to π∗ transition and n to π∗ transition. X-ray diffraction pattern confirms the amorphous nature of the polymer. Scanning electron microscopic images show the new morphology of spherical granular sponge like structures in the range of 100 to 200 nm. Conducting properties of the copolymers were studied using four probe method. Copolymers doped with DBSA showed an increased conductivity in the order of 10–4 S/cm. These copolymers are found to be more soluble in polar solvents comparing to polyaniline homopolymer.
Study of Mixed Micelles of Promethazine Hydrochloride (PMT) and Nonionic Surfactant (TX-100) Mixtures at Different Temperatures and Compositions

Abstract
Herein, we have investigated the interaction between a phenothiazine drug promethazine hydrochloride (PMT) and nonionic surfactant t-octylphenoxypolyethoxyethanol (TX-100) in aqueous solutions using a conductometric technique at different temperatures and compositions. The evaluated critical micelle concentration (cmc) values are lower than cmc
id values suggesting attractive interactions of mixed micelles components. It is observed that with the increase in temperature, the cmc value increases first and after the value decreases at higher temperature. At 298.15 K, the maximum cmc values were attained in presence or absence of TX-100. The bulk properties of solution were studied by means of different theoretical models reported in the literature such as Clint, Rubingh, Motomura, and Rodenas for explanation and comparison of results of different binary mixtures of the drug and TX-100. The negative values of interaction parameter (β) obtained from the regular solution theory (RST) recommend synergistic interactions. Activity coefficients (f
1 and f
2) calculated by all theoretical models used herein were obtained to be always below unity indicating nonideality in all binary mixtures. Thermodynamic parameters (like standard Gibbs energy (ΔG°m), enthalpy (ΔH°m), and entropy (ΔS°m)) are also evaluated which propose dehydration of hydrophobic portion of the drug at higher temperatures. The above results obtained may be helpful in model drug delivery systems.
Study of Underwater Contact Angles for Formulation of Fatliquoring Emulsions Using Green Surfactants
Authors: Goswami Anik , Bhagwat Sunil S. 
Published: May 2015

Abstract
Contact angles of pure water, partially sulphated groundnut oil and different surfactant solutions on glass, Stainless Steel, Teflon and different other polymer surfaces have been measured. The contact angles of oil on various surfaces underwater and under different surfactant solutions were also measured. These two contact angles have been found to be linearly related with a slope close to 1. However, the underwater contact angles have been found to deviate significantly from the prediction based on Young's equations which have been attributed to the possible modifications of the surfaces underwater due to adsorption of surfactants. Based on the observed oil underwater contact angles, comparative efficiencies of fatliquoring have been obtained. Weight gain measurements in various fatliquoring solutions containing surfactants and oil have been carried out with the wet blue leather samples. The results show that the contact angle of oil underwater correlates well with the efficiency of leather wetting.

Published: May 2015

Abstract
Dynamic interfacial tension (IFT) behaviors of dialkylbenzene sulfonate (DAS)/heavy alkylbenzene sulfonate (HABS)/dodecylbenzene sulfonate (LAS) ternary mixture solutions against a homologous series of alkanes were studied. On the basis of our experimental results, one can find that the lipophilic ability of DAS was stronger than that of HABS. At the lower content of LAS, the ternary system was oil soluble; at the higher content of LAS, the ternary system was water soluble. An IFT in the 10–
3 mN/m range can be obtained for the ternary system against long-chain alkanes (decane, dodecane) under the condition that the content of LAS was 30 %. A dynamic IFT of 10–
4 mN/m order of magnitude was observed against decane. The hydrophilic-lipophilic ability of the surfactant plays an important role in dynamic IFT behavior. With increasing content of LAS, the alkane carbon number of ternary mixture solutions for producing the lower IFT had a tendency to lower.

Published: May 2015

AbstractThe supply of glacier water to La Paz city, Bolivia, between 1963 and 2006 was assessed at annual and seasonal timescales based on the mass-balance quantification of 70 glaciers located within the drainage basins of La Paz. Glaciers contributed ∼15% of water resources at an annual scale (14% in the wet season, 27% in the dry season). Uncertainties in our estimation are related to the assumed constant precipitation (∼0.5% for ice-free areas and up to 6.5% for glaciated areas), the constant runoff coefficient (∼1%), the surface areas of the glaciers and catchments (∼5%) and the mean mass-balance uncertainty of the 21 glaciers used to obtain the mass balance of the 70 glaciers (12% of the total discharge). Despite the loss of 50% of the glacierized area during the study period, runoff at La Paz did not change significantly, showing that increase in ice melt rates compensated for reduction in the surface area of the glaciers. In the future, assuming complete disappearance of the glaciers and no change in precipitation, runoff should diminish by ∼12% at an annual scale, 9% during the wet season and 24% during the dry season.

Published: May 2015

Premise of the study:Here we present a series of protocols for RNA extraction across a diverse array of plants; we focus on woody, aromatic, aquatic, and other chemically complex taxa.Methods and Results:Ninety‐one taxa were subjected to RNA extraction with three methods presented here: (1) TRIzol/TURBO DNA‐free kits using the manufacturer's protocol with the addition of sarkosyl; (2) a combination method using cetyltrimethylammonium bromide (CTAB) and TRIzol/sarkosyl/TURBO DNA‐free; and (3) a combination of CTAB and QIAGEN RNeasy Plant Mini Kit. Bench‐ready protocols are given.Conclusions:After an iterative process of working with chemically complex taxa, we conclude that the use of TRIzol supplemented with sarkosyl and the TURBO DNA‐free kit is an effective, efficient, and robust method for obtaining RNA from 100 mg of leaf tissue of land plant species (Embryophyta) examined. Our protocols can be used to provide RNA of suitable stability, quantity, and quality for transcriptome sequencing.

Premise of the study:Viola elatior (Violaceae) is a Eurasian perennial plant species in which French populations are threatened by anthropogenic pressures. Microsatellite primers were developed to investigate its genetic structure and diversity.Methods and Results:Eight microsatellite markers were isolated using next‐generation sequencing. Loci were amplified and screened for 138 individuals in 17 populations from France. Two of the eight polymorphic loci presented no variability across populations. The total number of alleles per locus varied from two to four. Observed heterozygosity ranged from 0.051 to 1.000. All primers amplified successfully in the closely related species V. pumila.Conclusions:This set of microsatellites offers a valuable tool for assessing population genetic diversity of the species to improve its conservation and base management efforts. High observed heterozygosity values probably reflect the particular mating system of the species and suggest an important tendency to clonality.

Strongly Summable Ultrafilters, Union Ultrafilters, and the Trivial Sums Property
Authors: Fernández Bretón David J. 
Published: May 2015

AbstractWe answer two questions of Hindman, Steprāns, and Strauss; namely, we prove that every strongly summable ultrafilter on an abelian group is sparse and has the trivial sums property. Moreover, we show that in most cases the sparseness of the given ultrafilter is a consequence of its being isomorphic to a union ultrafilter. However, this does not happen in all cases; we also construct (assuming Martin's Axiom for countable partial orders, i.e., , a strongly summable ultrafilter on the Boolean group that is not additively isomorphic to any union ultrafilter.
SILICA-REINFORCED EPOXIDIZED NATURAL RUBBER TIRE TREADS — PERFORMANCE AND DURABILITY
Authors: Martin Pamela J. , Brown Paul , Chapman Andrew V. , Cook Stuart 
Published: May 2015

ABSTRACTConcerns regarding climate change and public health have compelled governments to reduce the environmental impact of transport. Many countries are introducing tire labeling and legislation targeting rolling resistance, wet grip, and noise. The proposed U.S. tire label also includes wear performance. Implementation of tire labeling is enabling buyers to choose better tires. The tire industry is responding to these demands and is developing the next generation of green tires. Current passenger tire tread technology is primarily petroleum based; however, the long-term availability of fossil-fuel supplies is limited. Thus a further step to minimize the environmental impact and carbon footprint of tires over their life cycle is to use sustainable materials not derived from fossil-fuels. Sumitomo Rubber Industries used epoxidized natural rubber (ENR) reinforced with silica in their route to a greener fossil-fuel free tire (the ENASAVE 100). At 25 mol% epoxidation, ENR has a glass transition temperature (Tg) most suitable for tread applications. Silica-filled ENR-25 tread compounds deliver lower rolling resistance, hence reduced fuel consumption, and enhanced wet and ice traction compared with benchmark premium passenger or truck treads. Optimization of wear performance to extend product durability is a current focus of research. However, correlation between laboratory abrasion and on-the-road tire wear is notoriously poor. The Tun Abdul Razak Research Centre (TARRC) have used light microscopy and transmission electron microscopy (TEM) to ascertain a mechanistic insight into tread wear, using results from wear studies on-the-road and laboratory abrasion. The results indicate that the mechanism of on-the-road tire wear differs from that of in-laboratory Akron abrasion tests.
Fascination, Musical Tourism, and the Loss of the Balkan Village (Notes on Bulgaria’s Koprivshtitsa Festival)
Authors: MacMillen Ian 
Published: May 2015

AbstractFor American Balkan music tourists, it is disillusioning to reconcile the Balkan village (a long-imagined source of fascination) with the urbanity they encounter in Bulgaria. The Koprivshtitsa festival, however, does offer visitors images of the "folk." Based on fieldwork and surveys conducted with tourists, the article examines the varied expectations that festival attendees hold for Koprivshtitsa as timeless village, cultural center, and contemporary town, and calls for an ethnomusicological consideration of the nature and role of fascination within musical tourism. It concludes by relating "meaningful blindness" (integral to these tourists’ fascination) to their imaginings, arguing that sonic encounter in situ brings fascination not to an end but rather to a more self-aware stage of subject-to-object relationship, through the reciprocal witnessing of Selves and Others.
Terrains of Bollywood Dance: (Neoliberal) Capitalism and the Transformation of Cultural Economies
Authors: Morcom Anna 
Published: May 2015

Abstract
This article explores ways of theorizing cultural change in contexts of liberalization and rapid economic growth. I focus on post-1990s India, looking on the one hand at the emergence of a Bollywood dance craze within middle class (transnational) India, and, on the other hand, at the rise of dance bars, where girls danced seductively for a male audience, a phenomenon that was subject to a vigorous moral campaign and a ban. I explore capitalism in its ability to (indiscriminately) fuel, scale, and feed phenomena as well as its production of class and disparity. I also look at lavish expenditure and ostentatious show in contexts of music and dance, exploring the connections yet contradictions of the vast surpluses of capitalism, the use of performing arts as a medium to display this money-power as status, and ideologies of productivity and industriousness and, on the other hand, of waste. I further analyze the unevenness, unintended consequences, and powerfully moral dimensions of (neoliberal) capitalism through contextualizing it as a form of liberalism. Thus I examine the ways in which we can understand the sheer pervasiveness of capitalism and its transformational power, yet also its unevenness and unpredictability, its dystopias as well as utopias.
Moonscapes and Mallee Scrub: Remembering Remembering
Authors: Miller Andrew 
Published: May 2015

Many 'life writers' in the twenty-first century are turning to digital platforms to tell their stories. Some life writers are combining 'prose' and 'visual elements' to expand their meaning-making capabilities beyond traditional narrative.In Moonscapes and Mallee Scrub I have turned to the visual to tell the story of my mother's mysterious death in 1974. This text draws upon multimodal elements and a range of different texts to form a 'graphic-memoir-bricolage' designed for online viewing. The resulting 'visual-verbal' text explores both the events that took place and the difficulties of depicting reflections on earlier reflections in the telling of that story. What results is a complex multimodal text that raises as many questions as it offers answers. But this, in the end, is the nature of memory and memoir - at least for this author!

ObjectiveThe aim was to estimate odds ratios (ORs) of associations between family history of arthritis, osteoporosis, and carpal tunnel syndrome and prevalence in a real‐world population, uncovering family histories of related conditions that may increase risk because of shared heritability, condition pathophysiology, or social/environmental factors.MethodsUsing data from 156,307 participants in the All of Us (AoU) Research Program, we examined associations between self‐reported first‐degree family history of five common types of arthritis (fibromyalgia, gout, osteoarthritis [OA], rheumatoid arthritis, and systemic lupus erythematosus [SLE]), osteoporosis, and carpal tunnel syndrome and prevalence. We evaluate associations across seven conditions and performed stratified analyses by race and ethnicity, sex, socioeconomic differences, body mass index, and type of affected relative.ResultsMore than 38% of AoU participants reported a family history of any arthritis, osteoporosis, or carpal tunnel syndrome. Adults with a family history of any arthritis, osteoporosis, and carpal tunnel syndrome exhibited 3.68 to 7.59 (4.90, on average) odds of having the same condition and 0.70 to 2.10 (1.24, on average) odds of having a different condition. The strongest associations observed were between family history of OA and prevalence of OA (OR 7.59; 95% confidence interval [95% CI] 7.32–7.88) and family history of SLE and prevalence of SLE (OR 6.34; 95% CI 5.17–7.74). We additionally uncover race and ethnicity and sex disparities in family history associations.ConclusionFamily history of several related conditions was associated with increased risk for arthritis, osteoporosis, and carpal tunnel syndrome, underscoring the importance of family history of related conditions for primary prevention.image

ObjectiveHealth literacy is an important social determinant of health, with limited health literacy associated with worse health outcomes. This study examined the associations between limited health literacy with patient‐reported outcomes and disease activity/damage among 267 Black women with active systemic lupus erythematosus (SLE) enrolled in the Peer Approaches to Lupus Self‐Management (PALS) program.MethodsThe three‐item Chew Health Literacy Screening was used to dichotomize those reporting in the “limited” range on any item with outcomes compared via generalized linear models. Baseline surveys and assessments obtained at study entry as part of the PALS study were used. Primary outcomes included disease activity and lupus damage; other secondary outcomes included patient activation, self‐efficacy, physician/patient communication, and quality of life.ResultsThe study included 267 Black women with SLE. In covariate‐adjusted analyses, participants with limited health literacy (88 [33%]) were more likely to have lower patient activation (Patient Activation Measure P < 0.0001), lower self‐efficacy (Lupus Self‐Efficacy P < 0.0001), higher lupus damage (self‐administered Brief Index of Lupus Damage P = .016), higher disease activity (Systemic Lupus Activity Questionnaire symptom severity P = 0.006), and worse physician/patient communication (patient‐centered care P < 0.0001) compared to those with adequate health literacy. Those with limited health literacy also reported worse lupus quality of life (P = 0.0004) and greater levels of stress (Perceived Stress Scale‐4 P < 0.0001) and were 2.4 times more likely to have probable major depression (Patient Health Questionnaire Depression Scale‐8 of ≥10 P = 0.004) and probable anxiety disorder (General Anxiety Disorder‐7 of ≥10 P = 0.007) compared to those with adequate health literacy.ConclusionBlack women with SLE and limited health literacy have worse clinical outcomes and represent a particularly vulnerable population with significantly disparate health outcomes. These findings suggest health literacy and complexities of managing SLE may impair clinical care in multiple domains, ultimately contributing to higher disease activity and death/damage, and are important to address in clinical care and future interventions in patients with SLE.

AbstractDeveloping high mass‐loading electrodes is crucial for enhancing the energy density of current batteries, yet challenges such as poor rate performance and cycling instability must be addressed. Spin charge storage on transition metal nanoparticle surfaces, characterized by rapid charging and the absence of phase transitions, offers an ideal storage behavior for high mass‐loading electrodes. In this study, electrospinning is utilized to fabricate free‐standing carbon nanofibers incorporating Co nanoparticles for high‐mass loading and high‐performance anodes. The resulting anode, with a maximum mass loading of 6.8 mg cm−2, exhibits remarkable cycle stability and high‐rate performance of 2 A g−1 at a capacity over 3 mAh cm−2, superior than reported results. Magnetometry and electron paramagnetic resonance spectroscopy are employed to monitor the charge storage mechanism of the Co@CNFs, involving both the reversible formation of a spin capacitance and the growth of radical anions in the solid electrolyte interface. Additionally, in situ X‐ray diffraction and optical microscopy provide direct evidence of the absence of mechanical stress‐induced phenomena within the spin charge process, attributed to high‐rate capable lithium storage under high mass loading. The strategic approach presented herein offers a reliable methodology for engineering high‐energy‐density lithium‐ion batteries.

Published: August 2024

AbstractComposite filaments are of considerable interest in research due to their exceptional performance characteristics and broad applicability. In this study, highly electrically conductive composite filaments comprising cellulose nanofibrils (CNF) and silver nanowires (AgNWs) are carefully prepared, accompanied by the proposition of an integrated microwave‐microfluidic synthesis method for AgNWs. The proposed reaction system exhibits a remarkable capability for swift AgNW synthesis, with a space‐time yield of 1.2 × 104 g (h·m3)−1, approximately five times superior to that achievable through conventional batch reactor methodologies. The microwave‐assisted microfluidic synthesis of AgNWs introduces a novel aspect to the extensive research on 1D nanomaterials. The design of experiments and multi‐objective Bayesian optimization are integrated iteratively to converge toward the global optimum, aiming to enhance screening efficiency and achieve a balanced outcome by maximizing aspect ratio and minimizing size for AgNWs. The AgNWs synthesized under optimal conditions has a diameter of ≈50.4 nm and an aspect ratio of ≈555. Subsequently, they are integrated into composite filaments with CNF, resulting in electrical conductivity and tensile strength of the composite filaments at values of 8.35 × 105 S m−1 and 186 MPa, respectively, surpassing those reported in existing literature for other analogous materials.
