Authors: Fatimah Fatimah , Adinugraha Hendri Hermawan
Published: June 2024

This study intends to analyze Strengths, Weaknesses, Opportunities, and Threats (SWOT) on Shopee e-commerce in order to identify its advantages, disadvantages, opportunities, and threats. It has been noted by multiple studies that Shopee is the most popular e-commerce site in Indonesia, but practical experience in the field indicates that there are still a lot of complaints from customers regarding Shopee e-commerce. This research uses a qualitative descriptive approach by conducting a SWOT analysis (Strengths, Weaknesses, Opportunities, Threats). This research uses primary data obtained through observation. The data was obtained from direct observation using gadgets on the Shopee application. The ensuing data analysis shows that Shopee's reputation is its greatest asset, that it is not an Indonesian e-commerce company, that there are several rivals with comparable business models, and that there is a potential for a marketplace business that is not restricted by time or location. Based on these findings, Shopee may strengthen its opportunities and strengths while decreasing its threats and weaknesses by putting the S-O, W-O, S-T, and W-T strategies into practice. The S-O strategy contains opportunities that can be maximized. The W-O strategy contains a way out so that opportunities are not wasted. The S-T strategy contains how to respond to threats with the strengths possessed. The W-T strategy contains solutions to threats that may arise.
Genetic variation in drought stress tolerant rice variety NSIC Rc9 (Apo) through In Vitro mutagenesis
Authors: Cabusora Christopher , Desamero Nenita
Published: June 2024

In vitro mutagenesis, a technique combining tissue culture and irradiation, of the drought-tolerant rice variety National Seed Industry Council (NSIC) Rc9 (Apo), resulted in the generation of an induced mutant population. Irradiation of gamma rays at four doses (10 Gy, 30 Gy, 50 Gy, and 70 Gy) was applied to callus pieces derived from tissue-cultured mature seeds. The control (0 Gy) determined the effect of irradiation doses on tissue culture response in callus induction and regeneration. A decreasing trend in callus induction and regeneration efficiency was observed with the increasing dosage of gamma ray. Increasing the gamma ray irradiation doses also increased the incidence of necrosis. The irradiated calli regenerated green plantlets, which produced the IVM2 mutant population. The variability evaluation showed a wide variation in agro-morphological traits, viz., pigmentation in basal leaf sheath, leaf blade, ligule, and collar, angles of leaf blade, culm and flag leaf, panicle exsertion, axis, type and secondary branching, grain size and shape, flowering days, plant height at maturity, panicle length and productive tiller number of the mutant population derived from the combination of tissue culture and gamma irradiation, compared to the variability induced using tissue culture alone identifying 30 Gy and 50 Gy with the most induced variability. The cluster analysis supported the variation of the mutants from the wild type, NSIC Rc9, in terms of phenotypic characteristics. The results showed the efficiency of in vitro mutagenesis in inducing a larger spectrum of mutation compared to using tissue culture and gamma irradiation singly.

Authors: Tulipan Jaren , Ventura Jey-R
Published: June 2024

The wastewater generated during the plastic recycling is an aspect that is often overlooked in the process. This wastewater contains pollutants that can affect the environment and human health. To address this problem, a study was conducted to design and evaluate the performance of an anoxic-oxic (AO) system and an anoxic-oxic-oxic (AO2) system in treating plastic recycling wastewater. Additionally, the study collected wastewater from a plastic recycling company and activated sludge from a sewage treatment plant to test the viability of biological treatment for treating plastic recycling wastewater. The results showed that both systems were effective at reducing chemical oxygen demand (COD), with the AO system having a higher percent COD removal (98.13%) than the AO2 system (85.33%). Also, there were 18 unique colonies isolated from the wastewater and activated sludge. Overall, the study concludes that biological treatment can be used to treat plastic recycling wastewater, and the design of upscaled system is crucial to fully solve the wastewater problem.

Políticas públicas de saúde mental como promotoras de cidadania e (re)inserção social: um novo lugar para ser feliz?
Authors: Michelle Pereira Albuquerque Flávia
Published: June 2024

Esta obra pretende produzir reflexões sobre a saúde mental e apresenta um estudo do município de Santa Rosa (RS). A assistência ao doente mental, por muitos anos, foi centrada nos hospitais psiquiátricos, locais da prática e do saber médico. O modelo de atenção constituía-se de internação e medicalização dos sintomas do transtorno mental, excluindo os sujeitos dos seus vínculos familiares e sociais. Somente em 2001 ocorreu a Reforma Psiquiátrica, o que proporcionou o começo da reorganização da saúde mental no Brasil, que foi avançando, aos poucos, conforme surgiam novas legislações brasileiras e internacionais. “Políticas públicas de saúde mental como promotoras de cidadania e (re)inserção social: um novo lugar para ser feliz?” defende, entre outros aspectos: a importância da rede de atendimentos em saúde mental; a necessidade de superar desafios e estigmas ainda existentes nessa trajetória de mudança do modelo de cuidado prestado ao indivíduo com transtorno mental; a construção de políticas intersetoriais integradas que ampliem o acesso e a rede de oferta de serviços; a integralidade, que se materializa à medida que o acolhimento, o vínculo e a responsabilização permitem a aproximação entre os atores envolvidos e eles dialogam e produzem novas possibilidades de vida, novas capacidades e novas habilidades.

Molecules that facilitate targeted protein degradation (TPD) offer great promise as novel therapeutics. The human hepatic lectin asialoglycoprotein receptor (ASGR) is selectively expressed on hepatocytes. We have previously engineered an anti-ASGR1 antibody-mutant RSPO2 (RSPO2RA) fusion protein (called SWEETS) to drive tissue-specific degradation of ZNRF3/RNF43 E3 ubiquitin ligases, which achieved hepatocyte-specific enhanced Wnt signaling, proliferation, and restored liver function in mouse models, and an antibody–RSPO2RA fusion molecule is currently in human clinical trials. In the current study, we identified two new ASGR1- and ASGR1/2-specific antibodies, 8M24 and 8G8. High-resolution crystal structures of ASGR1:8M24 and ASGR2:8G8 complexes revealed that these antibodies bind to distinct epitopes on opposing sides of ASGR, away from the substrate-binding site. Both antibodies enhanced Wnt activity when assembled as SWEETS molecules with RSPO2RA through specific effects sequestering E3 ligases. In addition, 8M24-RSPO2RA and 8G8-RSPO2RA efficiently downregulate ASGR1 through TPD mechanisms. These results demonstrate the possibility of combining different therapeutic effects and degradation mechanisms in a single molecule.

Brain age has emerged as a powerful tool to understand neuroanatomical aging and its link to health outcomes like cognition. However, there remains a lack of studies investigating the rate of brain aging and its relationship to cognition. Furthermore, most brain age models are trained and tested on cross-sectional data from primarily Caucasian, adult participants. It is thus unclear how well these models generalize to non-Caucasian participants, especially children. Here, we tested a previously published deep learning model on Singaporean elderly participants (55
−
88 years old) and children (4
−
11 years old). We found that the model directly generalized to the elderly participants, but model finetuning was necessary for children. After finetuning, we found that the rate of change in brain age gap was associated with future executive function performance in both elderly participants and children. We further found that lateral ventricles and frontal areas contributed to brain age prediction in elderly participants, while white matter and posterior brain regions were more important in predicting brain age of children. Taken together, our results suggest that there is potential for generalizing brain age models to diverse populations. Moreover, the longitudinal change in brain age gap reflects developing and aging processes in the brain, relating to future cognitive function.
When Platforms Challenge Professions: A Clash Between Models of Professionalism Among Swiss Hoteliers?
Authors: Surdez Muriel , Balsiger Philip , Jammet Thomas
Published: June 2024

The sociology of professions has begun to study how digital platforms impact the status and skills of professionals. Our article expands on this line of research by exploring how platforms challenge professions and how professionals react by advocating different types of professionalism. Based on a case study of hoteliers in Switzerland, we look at how the rise of online travel agencies (OTAs) has affected this professional group. Drawing on an analysis of data gathered through interviews with hoteliers (owners, managers, representatives of associations), our findings identify divergent responses to how platforms have undermined the jurisdiction built up by hoteliers. They highlight impacts on the capacity for self-regulation and customer service skills. The article contributes to the literature by showing that platforms foster divisions within occupational groups. Some members use platform tools because they fit their model of management-oriented professionalism. Others distance themselves from them, adopting a defensive professionalism.
Verbal Charms in a Nineteenth Century Swedish Book of Magic
Authors:   University of Naples “L’Orientale”, Mastrangelo Alessandra
Published: June 2024

This article deals with the analysis of a Swedish magic book dating back to the second half of the nineteenth century which I came across during a fieldwork in northern Sweden. The book consists of magical remedies and verbal charms for healing physical distress in humans and livestock, averting evil influences, and protecting against bewitchment. It represents a practical manual containing non-canonical words of power, whose purpose was the provision of verbal magical instruments for coping with everyday human problems, especially health-related issues. The article gives an overview of its content, introducing a healer and his healing methods, and publishes six charms from the book, together with translations into English. In terms of content, my attention is focused on the verbal charms, their formal features and narrative motives. Following earlier studies on the charm genre, I will characterise the charms from a structural and semantic standpoint. Concerning their textual and oral tradition, I aim to examine whether they can be located in the Swedish charm tradition and whether they present variation with other similar texts. As we shall see, they are texts which cross many borders: canonical / non-canonical, folk beliefs / Christian worldview, supernatural / natural.
Taboo Violation and Charming Initiation, as Expressed by Some Romanian Legends and Incantations Addressed to the Fairies
Authors:   Constantin Brăiloiu Institute of Ethnography and Folklore of the Romanian Academy, Jiga Iliescu Laura
Published: June 2024

Within the context of charmings, as it has been recorded among Romanians, the article aims to disclose the meaning of the theme of fairies’ taboo violation as a precondition necesary to gain sacred knowledge. In this regard, various certain incantations addressed to the fairies are examined, along with legends and third person accounts that underline the role played by these supernatural entities as numinous agents for initiation to the `secret` register of knowledge through a special form of communication, which in modern neuroscience terminology might be referred to as an ‚altered state of consciouness’, but which, in the emic terms of magic medicine is described as a disease, namely beeing taken by the fairies. In concordance with the idea of mutual exchanges between humans and the numinous, the one who accept the fairies’ authority and pay the price of being tormented by them, gain the gift of therapeutic and divinatory abilities.
How do Udmurts address their God(s)?
Authors:   INALCO, Paris, France, Toulouze Eva , Vladykina Tatiana ,   Department of Research in Philology, Udmurt Institute of History, Language and Literature, UdmFRC UB RAS, Izhevsk, Russia
Published: June 2024

This article relies on a long-term fieldwork experience: Eva Toulouze has attended Udmurt animistic ceremonies in Bashkortostan over a period of ten years and has collected there the uttered prayers. These prayers are the corpus upon which our linguistic reflections are articulated. The language of the prayers represents a particular register of the Udmurt language. They are deeply dialectal, and while today they are mostly transmitted through writing and the magic aspect is less emphasised, they belong to the oral tradition of incantations. In this article, we comment upon some of the peculiarities of these prayers. We explore the multiplicity of ways that the Udmurts formulate their requests to the deities: the different use of verbs and especially the sophisticated syntactical constructions. We are also interested by analysing the peculiar use of possessive markers, revealing that in the Udmurt worldview, the deity to which these prayers are addressed is all-encompassing: the happiness that the Udmurt ask for is the deity’s happiness, as is the rain and the insects against which they ask protection. It is the first time that these phenomena have drawn scientific attention and have been commented on.
Identification of Unnamed Non-human Agents in Kalevala-metric Incantations
Authors:   University of Helsinki, Finland, Karlsson Tuukka
Published: June 2024

Kalevala-metric poetry is an oral-poetic system of various genres, shared by multiple Finnic groups. In addition to epic and lyric, one of the prominent main genres of the oral tradition is formed by incantations. The Kalevala-metric incantations regularly invoke non-human agents, which are aligned with the performer in various ways. While these agents are often explicitly named and addressed, in some cases their identity remains unclear. By conducting a case study, the paper proposes that in many occurrences the unnamed agents are identifiable by examining textual cues and the emergent text-structure of the incantations. The results show that the identification of unnamed agents can be achieved by biographic-metrical and contextual analysis of the incantation texts.

Published: June 2024

Hematoma expansion (HE) is an important risk factor for death or poor prognosis in patients with hypertensive intracerebral hemorrhage (HICH). Accurately predicting the risk of HE in patients with HICH is of great clinical significance for timely intervention and improving patient prognosis. Many imaging signs reported in literatures showed the important clinical value for predicting HE. In recent years, the development of radiomics and artificial intelligence has provided new methods for HE prediction with high accuracy. Therefore, this article reviews the latest research progress in CT imaging, radiomics, and artificial intelligence of HE, in order to help identify high-risk patients for HE in clinical practice.

Authors: Rengaraj Ramya , Karunaivel Ragu , Thiyagarajan Sabarinathan , Alagiri Sivaranjini , Ali Saleem Mohamed
Published: June 2024

Introduction: Hepatitis B Virus (HBV) infection remains a significant public health concern globally, necessitating accurate and timely diagnostic methods. Immunochromatographic Tests (ICTs) and Electrochemiluminescence Assays (ECLIAs) are widely used assays for HBV detection due to their rapidity and cost-effectiveness. However, their diagnostic performance should be evaluated to ascertain their reliability. Aim: To detect the presence of Hepatitis B Surface Antigen (HBsAg) in the selected samples using ICT and ECLIA and to compare it with HBV Deoxyribonucleic Acid (DNA) using a molecular assay. Materials and Methods: A cross-sectional study was done with serum samples collected from patients visiting the hospital over a period of six months with prior ethical clearance. Serum samples were obtained from 57 patients suspected of HBV infection. The results of ICT, ECLIA, and HBV DNA viral load (by Polymerase Chain Reaction (PCR)) were cross-tabulated and assessed for differences in diagnostic sensitivity. The positivity and correlation of the ICT and ECLIA with PCR were estimated. All statistical analyses were performed using the R programming language. Results: Out of 57 samples, 53 (92.98%) tested positive in the ICT card test, and 54 (94.74%) were positive in the ECLIA method. McNemar’s test showed that the sensitivity of ICT and ECLIA differed significantly compared to HBV DNA PCR. There was a significant positive correlation between ECLIA and HBV-DNA PCR (Spearman correlation, r-value=0.28, p-value=0.035). Conclusion: The findings suggest that in settings where accurate diagnosis is critical, particularly for screening and monitoring treatment efficacy, molecular assays remain the preferred choice despite their higher cost and complexity. However, in resource-limited settings, ECLIAs can still play a valuable role in HBV screening programs.

Published: June 2024

The present study was conducted to know the knowledge level of beneficiaries farmers as compared to non-beneficiaries farmers about turmeric cultivation. The present study was conducted during the year 2015-16 and 2016-17 in Chhattisgarh plains. A sample size of 160 beneficiaries respondents, proportionate random methods were used and equal numbers of non-beneficiaries respondents were also selected randomly from the same villages. In this way, a total of 320 farmers were considered as respondents to respond as per the interview schedule design for the study. The study revealed that the majority of the beneficiaries (73.12%) and non-beneficiaries (75.62%) had a medium level of knowledge, followed by 19.38 percent of the beneficiaries and 20.63 percent of the non-beneficiaries had a low level of knowledge and 7.50 percent of the beneficiaries and 3.75 percent of the non-beneficiaries had a high knowledge about turmeric cultivation. The high level trend of knowledge of the respondents in beneficiaries need to be maintained in the same manner, whereas it would be desirable to develop knowledge of non-beneficiaries respondents to high level by involving them in extension programme i.e. training and demonstration etc.
The Rising Popularity of Online Lending in Indonesia: The New Opportunities for Banks (Push-Pull Mooring Perspective)
Authors: Hardayu Audisty Prana , Afifah Nur , Mustaruddin
Published: June 2024

Background and Purpose: Fintech lending, also known as online lending, has experienced fast growth in Indonesia in recent years through digital platforms. Online lending is supplanting the financial intermediation function hitherto predominantly held by banks. This study examines the factors influencing Indonesians' inclination to transition from traditional banking services to online lending. It seeks to understand the appeal of online lending, which has enabled it to supplant Indonesian banks in financial intermediation, employing the Push-Pull Mooring theory.
Methodology: This study used a nonprobability sampling technique to choose 200 respondents who are consumers of banking services and have transitioned to online lending. Data was gathered through Google Forms and subsequently analyzed utilizing SEM-PLS 4.0.
Findings: The findings indicate that pull variables exert the most significant impact on the inclination to transition to online lending, with push variables following closely behind. The variable "switching barrier" does not influence the intention to switch to online lending. However, switching costs and low financial literacy significantly impact the switching barrier. Additionally, the moderation effect does not enhance the relationship between dissatisfaction with banking and the appeal of online lending. Online lending has attracted users by providing a value proposition that includes easy digital onboarding, quick loan processing and payout, and unsecured credit options for unbanked customers. The influence of brand loyalty on customer choices when selecting an online lender is minimal.
Contributions: This study aims to enhance marketing theory and consumer behavior understanding by investigating the factors influencing Indonesians' intention to transition from traditional banking services to online lending, specifically focusing on Push-Pull and Mooring factors.

Enantia chlorantha (EC) is a dense forest tree found in the Eastern and Southern forests of Cameroon, Southern part of Nigeria, Gabon, Guinea, Ivory Coast, Liberia, Angola (Cabinda) and DR Congo (Province Bas-Congo) and it is mostly used for the treatment of malaria and typhoid fever. Despite its widespread use, the phytochemical and the Gas Chromatography-Mass Spectrometry (GC-MS) analysis remains largely undetermined. This study was carried out with the aim to evaluate the phytochemical composition of EC. The proximate and phytochemical tests were carried out using standard methods while the identification and the quantification of the bioactive components were determined by GC-MS single-phase ion mode and the spectra from THE detected compounds were matched with known compounds of the National Institute of Standards and Technology (NIST). The proximate analysis reveals that the plant is richest in crude fibre (47.30 ± 0.54% by dry mass), followed by total carbohydrate (28.13 ± 0.43%), crude protein (9.67 ± 0.32%), moisture content (8.30 ± 0.54%), ash content (3.00 ± 0.24%) and lastly lipids (1.60 ± 0.04%). The qualitative phytochemical composition reveals the presence of alkaloids, cardiac glycosides, flavonoids, steroids and trace amount of tannins. Forty-seven (47) bioactive chemical constituents and forty (40) fatty acid compounds were identified by GC-MS. These include Oleic acid (17.70 %), n-Hexadecanoic acid (9.31%), 1-Hexyl-2-nitrocyclohexane (3.71%), Kauran-18-al, 17-(acetyloxy)-, (4. beta.) - (3.05%) as the predominant. The study revealed that Enantia chlorantha could be a useful source of nutrients and the bioactive chemical constituents may serve as potential drug target needed for drug discovery and development to cure a particular ailment and the brand of the carbonated drink may also be used as solvent of choice apart from water and alcohol.
Impediments to Effective Healthcare Delivery among Rural Women in Cross River State, Nigeria
Authors: Etobe Eteng Ikpi , Udom Hannah Thompson , Etobe Utibe E. I.
Published: June 2024

Rural women often face unique challenges in accessing and utilizing healthcare services, including limited access to healthcare resources, geographic isolation, and cultural and social barriers. To better understand the factors that influence healthcare delivery among rural women in Cross River State, Nigeria, this theoretical literature draws on social determinants of health and social exchange theories. Social determinants of health highlight the importance of social and economic factors, such as income, education, and housing, in shaping health outcomes. Social exchange theory, on the other hand, emphasizes the importance of interpersonal relationships and social interactions in shaping behavior and decision-making. Using these frameworks, we argue that healthcare utilization among rural women in Cross River State is influenced by a complex interplay of factors, including cultural beliefs about health and healthcare, socioeconomic status, gender roles, and access to healthcare resources. Our discussion, however, highlights the importance of social support networks and trust in healthcare providers in facilitating healthcare utilization among rural women. These factors can help mitigate the negative effects of geographic isolation and limited healthcare resources. Access to transportation is also critical in overcoming geographic barriers to healthcare utilization. Finally, we identify gender roles and cultural beliefs around healthcare as key barriers to access and utilization. To address these barriers and improve healthcare delivery for rural women, interventions may include community-based outreach programs, education on cultural competency for healthcare providers, and policies to address transportation barriers and other social determinants of health. In conclusion, this paper contributes to the understanding of factors affecting healthcare delivery in rural areas, emphasizing the importance of addressing social determinants of health and improving healthcare infrastructure to improve health outcomes for rural women. This paper however has implications for healthcare providers, policymakers, social workers and researchers seeking to develop effective interventions and policies to address healthcare disparities in rural communities.

Impact of Bio-stimulants and Integrated Nutrient Management Sustainable Wheat Production: An Overview
Authors: Mohan Jag , Tomar Vikas , Sahil  , Mittan Sahil , Prince
Published: June 2024

A sufficient and well-balanced supply of plant nutrients is essential for increasing wheat crop output. The high cost of chemical fertilisers has prevented Indian farmers, who are primarily marginal and small-scale farmers, from providing these energy-dense crops with the recommended doses of nutrients. Instead, locally available organic sources of nutrients have been shown to increase crop productivity and decrease the need for chemical fertilisers. Under integrated nutrition management, the nutrients (N, P, K, and Zn) can be supplied via fertilisers, organic manures, bio-fertilizers, bio-stimulants, and their combined applications.
Varietal adaptation at various locations and sowing dates is determined by the differences in phenology, growth habits, and requirements for temperature and photoperiod units among wheat varieties. In order to determine the growth patterns, physiological features, and yield attributes that will favourably influence the grain yield and biomass in wheat under normal and late seeded settings, a comparative evaluation of varieties appropriate for early, normal, and late sown conditions is necessary. The reaction of wheat cultivars to integrated nutrition management techniques in wheat crops grown under typical and late planting circumstances is reviewed in this review.
Corporate Performance in Nigeria: Insights from Economic-Specific Shocks
Authors: Omoregie Osaretin Kayode , Olofin Sodik Adejonwo
Published: June 2024

Aims: This study investigated the impact and contributions of macroeconomic factors to corporate performance by considering the contributions of three key market segments in the economy: international, money, and goods markets.
Methodology: This study concentrated on Nigeria, and the time series data span from January 1995 to December 2022. Given the mixed order of integration among the variables of interest, the analysis was based on the SVAR/HD estimations, which investigate shocks based on theoretical restrictions and generate each variable's contributions to corporate performance. Inferences are based on the impulse response, variance decomposition and historical decomposition.
Results: Based on Structural One S.D. Innovations ± 2 S.E, the study's results underscore the vulnerability of Nigerian businesses to exogenous shocks and speculative markets (44.63%), with the international market exerting the most significant influence on corporate performance through exchange rate movements (32% of 44.63%), followed by the money market. Notably, the variables under consideration demonstrate varying relationships over different time periods. In the short-term, oil prices, government deficits, and inflation positively impact corporate performance, but this effect reverses to negative in the medium to long term. Conversely, the exchange rate initially has a negative effect but shows a positive long-term impact. Surprisingly, the impact of money supply and economic growth on corporate performance is found to be negligible. The study further reveals that firm-level endogenous shocks exert more influence on corporate performance development (55.37%) than exogenous macroeconomic factors (44.63%).
Conclusion: This study provides actionable insights for decision-makers. The research suggests that corporate managers can enhance firm performance by adopting strategic hedging strategies against adverse exogenous international market and money market factors while focusing more on endogenous factors and choices within their direct control, which accounts more for corporate performance outcomes than non-controllable exogenous factors. Policymakers should pursue policies that enhance the macroeconomic climate within which businesses operate, especially in the areas of stable exchange rate, interest rate and inflation targeting policies.

The present study was framed to determine the combining ability and the extent of heterosis in maize using line × tester design at maize section, Bihar Agricultural University, Sabour, Bhagalpur. Crosses were made involving ten lines and three testers in Rabi, 2019-20 for the study. 30 Crosses along with 13 parents and 2 checks were evaluated in randomized block design with two replications during kharif, 2020. The hybrids DHM 117 and SHM 1 were used as checks. Data were recorded on 13 morphological traits. The contribution of lines is found to be greater than that of the testers for most of the characters studied. On the basis of GCA effects, the lines VL109476, VL109475, VL1010848, VL109479 and tester VP15295 were identified as good combiners for grain yield, whereas the line VL1017524 and the tester SML-1 were also identified as good combiner in terms of earliness. These can be used as parents in multiple hybridization programme. On the basis of SCA effects, the crosses VL109476 x V P15295, VL1010763 x VP15295, VL1018419 x VP15295 and VL109475 x SML-1 were identified as good specific combiners for grain yield, whereas on the basis of standard heterosis VL109476 x V P15295, VL1010763 x VP15295, VL109475 x SML-1 and VL109479 x SML-1 were superior to the better check in grain yield. The identified hybrids may be tested on large scale multi-location trial and in farmers’ field before commercial utilization.
Mechanistic Considerations of Bending‐Strain Effects within Organic Semiconductors on Polymer Dielectrics

The development of organic transistors for flexible electronics requires the understanding of device behavior upon the application of strain. Here, a comprehensive study of the effect of polymer‐dielectric and semiconductor chemical structure on the device performance under applied strain is reported. The systematic change of the polymer dielectric results in the modulation of the effects of strain on the mobility of organic field‐effect transistor devices. A general method is demonstrated to lower the effects of strain in devices by covalent substitution of the dielectric surface. Additionally, the introduction of a hexyl chain at the peripheries of the organic semiconductor structure results in an inversion of the effects of strain on device mobility. This novel behavior may be explained by the capacitative coupling of the surface energy variations during applied strain.

The natural transmission cycle of Yellow Fever (YF) involves tree hole breeding mosquitoes and a wide array of nonhuman primates (NHP), including monkeys and apes. Some Neotropical monkeys (howler monkeys, genus Alouatta) develop fatal YF virus (YFV) infections similar to those reported in humans, even with minimum exposure to the infection. Epizootics in wild primates may be indicating YFV circulation, and the surveillance of such outbreaks in wildlife is an important tool to help prevent human infection. In 2001, surveillance activities successfully identified YF‐related death in a black‐and‐gold howler monkey (Alouatta caraya), Rio Grande do Sul State (RGS) in southern Brazil, and the YFV was isolated from a species of forest‐dwelling mosquito (Haemagogus leucocelaenus). These findings led the State Secretariat of Health to initiate a monitoring program for YF and other 18 arboviral infections in Alouatta monkeys. The monitoring program included monkey captures, reporting of monkey casualties by municipalities, and subsequent investigations. If monkey carcasses were found in forests, samples were collected in a standardized manner and this practice resulted in increased reporting of outbreaks. In October 2008, a single howler monkey in a northwestern RGS municipality was confirmed to have died from YF. From October 2008 to June 2009, 2,013 monkey deaths were reported (830 A. caraya and 1,183 A. guariba clamitans). Viruses isolation in blood, viscera, and/or immunohistochemistry led to the detection of YF in 204 of 297 (69%) (154 A. g. clamitans and 50 A. caraya) dead Alouatta monkeys tested. The number of municipalities with confirmed YFV circulation in howlers increased from 2 to 67 and 21 confirmed human cases occurred. This surveillance system was successful in identifying the largest YF outbreak affecting wild NHP ever recorded. Am. J. Primatol. 74:68–76, 2012. © 2011 Wiley Periodicals, Inc.
SEC‐MALS study of dynamic structuring of natural rubber: Comparative study of two Hevea brasiliensis genotypes

Published: October 2011

The dynamic structuring of natural rubber (NR) was studied selecting two specific Hevea brasiliensis genotypes (RRIM600 and PB235) to prepare model samples. The mesostructure (macromolecular structure + aggregates or gel) of NR samples was studied by SEC‐MALS. The NR samples were analyzed after (i) slow structuring (18 months' storage at room temperature) and (ii) fast structuring (stored for 24 h on P2O5 at 60°C). This study showed that the macromolecular structure, especially Mn, and the total gel rates were dramatically modified after fast structuring. For genotype RRIM600, the aggregates formed during fast structuring were essentially macroaggregates, whereas for genotype PB235 mostly microaggregates were formed. These results indicate that the dynamic structuring of NR is dependent on genotype. Depending on the genotype, for extreme conditions (fast structuring), it can be assumed there was percolation between elementary bricks, probably microaggregates, or no percolation. Although the mechanisms of dynamic structuring are quite complex and should be multifactors dependent, on the basis of our results, the degree of percolation seems to be partly dependent on the quantity of short polyisoprene chains initially present in the NR samples. © 2011 Wiley Periodicals, Inc.

Cellulose nanofibres and cellulose nanowhiskers based natural rubber composites: Diffusion, sorption, and permeation of aromatic organic solvents

Published: October 2011

This article investigates the transport behavior of three aromatic organic solvents, viz. benzene, toluene, and p‐xylene in natural rubber nanocomposite membranes containing cellulose nanofibres (CNFs) and cellulose nanowhiskers (CNWs) isolated from bamboo pulp. The solvent molecules act as molecular probes to study the diffusion, sorption, and permeation through the nanocomposites, and provide information on the nanocomposite structure and matrix–filler interactions. Both the nanocelluloses were found to decrease the uptake of aromatic solvents in nanocomposite membranes, but the effect was more significant in the case on nanofibers compared to nanowhiskers. Furthermore, the uptake decreased with increased penetrant size; being the highest for benzene and the lowest for p‐xylene. Transport parameters such as diffusion coefficient, sorption coefficient, and permeation coefficient have been calculated. Comparison of the experimental values of equilibrium solvent uptake with the predicted values indicated that both the nanocelluloses have restricted the molecular mobility at the interphase and thereby decreased the transport of solvents through the materials; being more significant for nanofibers. The results showed that both the used cellulosic nanomaterials act as functional additives capable of manipulating and tailoring the transport of organic solvents through elastomeric membranes, even at concentrations as low as 2.5 wt %. © 2011 Wiley Periodicals, Inc.

Published: October 2011

Polyoxymethylene (POM) has been widely utilized in industry due to its light weight properties in engineering plastics. At present, POM applications are expanding into the car industry, especially in fuel tanks. Hindered alkyl phenol derivatives have been used as antioxidants for POM; however, these compounds are easily extracted by solvents. Two antioxidants with new structures (N,N′‐triethylenedioxy‐bis(3‐tert‐butyl‐4‐hydroxy‐5‐methylhydrocinnamamide) and N,N′,N′‐tris[(3‐tert‐butyl‐4‐hydroxy‐5‐methylphenyl)propionyl‐3‐oxapentyl]melamine) were synthesized and characterized, and their performance as antioxidants for POM was investigated in the present study. The results revealed that N,N′‐triethylenedioxy‐bis(3‐tert‐butyl‐4‐hydroxy‐5‐methylhydrocinnamamide) has good heat aging resistance compared to existing antioxidants for POM, and N,N′,N′‐tris[(3‐tert‐butyl‐4‐hydroxy‐5‐methylphenyl)propionyl‐3‐oxa‐pentyl]melamine has good extraction resistance against solvents. © 2011 Wiley Periodicals, Inc.
