Authors: Nasution Fatimah Marwa 
Published: September 2021

Research has been conducted on the manufacture and characterization of pineapple leaf fiber composites – polypropylene matrix. Samples with comparison of pineapple leaf fiber composition: polypropylene matrix by 0 %: 100%, 5%: 95%, 10%:90%, 15%:85%, 20%;80%, and 25%:75%. The manufacture of SDN-PP composites, i.e. fiber soaked with NaOH 5% for 2 hours and then rinsed with clean water and dried, then weighed. Polypropylene and MAPP are effluxed with xylen solvent using a reflux device over a hot plate with a temperature of 17oC until melted. The polypropylene that has been diflux weighed in mass and pineapple leaf fibers are placed into a mold then pressed with a hot press at a temperature of 150oC for 30 minutes. The purpose of the study was to find out the physical and mechanical properties of pineapple leaf-matrix polypropylene fibers. Density values 0.75 g/cm3 to 0.9 g/cm3, water absorption values 0.54% to 14.38%, strong compressive values 25.09 MPa to 49.58 MPa, and strong values impact 9.74 J/mm2 to 34.18 J/mm2. Pineapple leaf fiber composite – the resulting polypropylene matrix can be categorized as a high-crust fiberboard (HF) and applied as a decorative board in accordance with the fiberboard standards set out in SNI 01-4449-2006.
Laser Cladding of Ni-Co-W Composite Coating on Stainless Steel to Enhance Wear Resistance
Authors: ZHANG Linlin , ZHANG Dawei 
Published: September 2021

Ni-Co-W composite coatings modified by different contents of Co-based alloy powder in the Ni-based alloy with 35 wt.% WC (Ni35WC) were deposited on stainless steel by laser cladding. The influence of compositional and microstructural modification on the wear properties has been comparatively investigated by XRD, SEM, and EDS techniques. It was found that the austenite dendrites in the modified coating adding 50 wt.% Co-based alloy were refined and a lot of Cr23C6 or M23(C, B)6 compounds with fine lamellar feature were formed around austenitic grain boundaries or in the intergranular regions. The contribution of element Co to the modification of Ni35WC coating is that it cannot only promote the formation of more hard compounds to refine austenite grains, but also refine the size of precipitates, and change the phase type of eutectic structure as a result of disappeared Cr boride brittle phases. A noticeable improvement in wear resistance is obtained in the Ni35WC coating with 50 wt.% Co-based alloy, which makes the wear rate decreased by about 53 % and 30% by comparison to that of the substrate and the Ni35WC coating, respectively. It is suggested that the improvement is closely related to the composite coating being strengthened owing to the increase of coating hardness, formation of a fine-grained microstructure caused by Co, and fine hard precipitate phases in the eutectic structure.
Violence: A Prescription of Hope for a Vulnerable Population
Authors: Smith Tonita , Amponsah Edith , Garman Lia 
Published: September 2021

Violence is a preventable disease that has long term effects on health. In the United States, violence has become an epidemic that disproportionately affects the African American community. Risk factors that contribute to the perpetration of youth violence include a combination of individual, relationship, community, and societal factors. Individual risk factors include a personal history of victimization of violence, high emotional stress, and exposure to violence and conflict. Family risk factors include low parental education, low income, poor family functioning and low parental involvement. Community risk factors include diminished economic opportunities, high concentration of poor residents, and socially disorganized neighborhoods – all of which are prevalent in communities with high rates of violence. Preventive strategies aimed at reducing violence need to be collaborative and community based. This multi-city project, A Prescription of Hope, aims to educate community members from Illinois and Missouri on the long- term effects of exposure to violence. The target population for Missouri is Ferguson, a small community with an approximate population of 21,035 (2017); however, it is recognized nationally for the demonstrations and unrest that erupted after the August 9, 2014 shooting death of 18-year-old Michael Brown. Worldwide, an estimated 200,000 homicides occur each year among youth aged 10–29 years, accounting for 43% of all homicide annually.

El propósito de este trabajo es explorar los límites de un subconjunto de los usos evalua-tivos del lenguaje: el discurso ofensivo. Nuestro objetivo es doble. Primero, introducimos la rela-ción que hay entre el contexto y las proferencias evaluativas, tal y como puede rastrearse en la literatura reciente acerca de la cuestión. Segundo, nos centramos en el estudio experimental de una interacción particular entre la información contextual y nuestras afirmaciones evaluativas: cuándo el contexto es capaz de convertir una pro-ferencia aparentemente descriptiva en una evalua-tiva. Para este segundo propósito, argumentamos, ciertas propuestas positivas recientes, a pesar de su mérito, son insuficientes.
The purpose of this paper is to explore the limits of a subset of the evaluative uses of language: offensive speech. More in particular, our goal is twofold. Firstly, we want to chart the relationship between context and evaluative utterances, as it stands in the current literature. Secondly, we focus on the experimental study of a particular interaction between contextual information and our evaluative claims –when the context is able to turn a seemingly descriptive utterance into an evaluative one. For this second purpose, we argue, certain recent positive proposals, in spite of their merit, come a bit short.
On the Threshold of Eurasia
Authors: Feldman Leah 
Published: September 2021

On the Threshold of Eurasia: Revolutionary Poetics in the Caucasus explores the idea of the Russian and Soviet “East” as a political, aesthetic and scientific system of ideas that contributed to the construction of Soviet discourses of ethnicity, empire, and literary modernity during the tumultuous first two decades of the twentieth century, from 1905 to 1929. It exposes connections between literary works, political essays, and orientalist history, geography, and ethnology written by Russian and Azeri Turkic Muslim writers and thinkers, many of whom have been unknown to Anglophone readers until now. Tracing translations and intertextual engagements across Russia, the Caucasus and western Europe, this book offers an alternative vision of empire, modernity and anti-imperialism from the vantage point of cosmopolitan centers in the Russian empire and Soviet Union. In this way, On the Threshold of Eurasia illustrates the pivotal impact of the literature of the Caucasus and the former Soviet periphery more broadly on the monumental aesthetic and political shifts of the early twentieth century.

Published: September 2021

Aim: Competition from weeds is an obstacle to profitable maize production. Knowledge of weed species limiting productivity is essential for sustainable management. A two years field experiment was conducted to evaluate the effect of a leguminous cover crop, akidi (Vigna unquiculata sub-sp sequipedalis) and two non-leguminous cover crops (melon and sweet potato) planted at three densities on weed flora composition and shift in maize at Jalingo, North-eastern Nigeria.
Study Design: There were 11 treatments replicated three times in a randomized complete block design.
Methodology: Low, moderate and high densities (20,000, 30,000 and 40,000 stands/ha respectively) of Akidi, Melon and Sweet potato (A1, A2, A3, M1, M2, M3, S1, S2, S3) with weeded (C1) and unweeded (C2) checks constituted the treatments laid out in a randomized complete block design replicated three times. Weed flora abundance, percentage density, percentage frequency, frequency index and percentage contributions were determined from a 50cm x 50cm quadrat thrown twice per plot at various phases of maize growth.
Results: Thirteen weed families made up of 11 broad leaves, one grass and one sedge were identified. The abundance was in the order Broad leaf > Grass > Sedges. The most abundant weed species were: Imperata cylindrica L (3.8), Mucuna utilis (3.0), Oldenlandia herbacea L. (2.6) Sida acuta Burm F, Tridax procumbens L. (2.5 each), Leucas martinicensis, Pennisetum pedicellatum (2.3 each). Commelina benghalensis, Cyperus difformis (3.5), Digitaria horizontalis, Fimbristylis littoralis (2.8 each). The influence of selected cover crops on individual weed percentage the contribution shows: Commelina benghalensis ( C2<C1 < M <S< A), Euphorbia hyssopifolia (C2<M/S < A<C1), Euphorbia heterophylla (M<S<A), Leucasmartinicensis (C1<C2<M<A<S), Mucunautilis (S<M<C1<C2<A) and Sida acuta (M<S<A<C2<C1) while grassy weeds, Imperata cylindrical (A<C2<S<M), Pennisetum pedicellatum (A<C2), Digitaria horizontalis (C1/ C2< A < M <S), Kyllinga squamulata (M/S <C2<A <C1). Commelina spp. increased in status from an accessory (21.2%) to abundance (66.7%) while others increased from rare to accessory (from 0.0 to 20-40%).
Conclusion: Akidi was more effective on broad-leaved weeds while melon and sweet potato were more effective on grasses and Commelina benghalensis need to be monitored.

Published: September 2021

AbstractFamilies play a critical role in supporting their children with autism spectrum disorder (ASD) and in advocating for their health and educational needs. However, many families around the world experience social, emotional, and financial difficulties, as well as challenges navigating various systems in search for the services and supports their children require. Colombia has made some recent strides in supporting the needs of families of children with ASD, but there is still concern among families that their children are not receiving adequate services. Thus, we were interested in learning more about what it was like to parent a child with ASD in Colombia. In particular, we focused on investigating the families' perceptions, experiences, and aspirations for their child with ASD by conducting focus group interviews. Four primary themes emerged from these interviews with Colombian parents, which included the impact of the disability diagnosis on the family, the systemic and societal challenges they faced, the strengths they saw in their child, and their future aspirations and expectations for their child. Implications for developing culturally responsive parent education programs are discussed.

Published: September 2021

ObjectiveTo investigate the perceived risk of coronavirus disease 2019 (COVID‐19) infection and outcomes as well as shielding practices among patients with rheumatoid arthritis (RA) during the COVID‐19 pandemic.MethodsWe surveyed participants with RA in a large health care system between July 16 and November 8, 2020. Participants reported RA treatment, COVID‐19 risk perception, and shielding practices (eg, masks, social distancing, and quarantining). We examined the association of demographic and disease‐specific factors with risk perception and the association of risk perception with shielding practices.ResultsOf 494 participants, 195 (40%), 169 (34%), and 130 (26%) strongly agreed, agreed, or were uncertain/disagreed that their RA put them at higher risk for COVID‐19 or poor outcomes, respectively. Younger age (odds ratio [OR]: 0.98), having a comorbidity (OR: 1.60), and biologic disease‐modifying antirheumatic drug (bDMARD) use (OR: 1.75) were independently associated with a higher perceived risk. Among those who strongly agreed, agreed, or were uncertain/disagreed that they had greater risk, 165 (85%), 118 (70%), and 69 (53%), respectively, practiced all three shielding measures (P < 0.0001). Those who strongly agreed or agreed that they were at higher risk were more likely to use all three shielding practices (OR: 4.16 and 1.97, respectively). bDMARD use and glucocorticoid use were associated with using all three shielding measures (OR: 1.99 and 1.81, respectively).ConclusionPerception of COVID‐19 risk among patients with RA varies substantially. Factors associated with perceived risk are different from those found to be associated with worse outcomes in observational studies. Greater perceived risk is associated with more strict shielding, which has implications for patient education and mental health.
Recent Progress on Synthesis, Characterization, and Applications of Metal Halide Perovskites@Metal Oxide
Authors: Duan Yanyan , Wang De‐Yi , Costa Rubén D. 
Published: September 2021

AbstractMetal halide perovskites (MHPs) have become a promising candidate in a myriad of applications, such as light‐emitting diodes, solar cells, lasing, photodetectors, photocatalysis, transistors, etc. This is related to the synergy of their excellent features, including high photoluminescence quantum yields, narrow and tunable emission, long charge carrier lifetimes, broad absorption spectrum along with high extinction absorptions coefficients, among others. However, the main bottleneck is the poor stability of the MHPs under ambient conditions. This is imposing severe restrictions with respect to their industrialized applications and commercialization. In this context, metal oxide (MOx) coatings have recently emerged as an efficient strategy toward overcoming the stabilities issues as well as retaining the excellent properties of the MHPs, and therefore facilitate the development of the related devices’ stabilities and performances. This review provides a summary of the recent progress on synthetic methods, enhanced features, the techniques to assess the MHPs@MOx composites, and applications of the MHPs@MOx. Specially, novel approaches to fabricate the composites and new applications of the composites are also reported in this review for the first time. This is rounded by a critical outlook about the current MHPs’ stability issues and the further direction to ensure a bright future of MHPs@MOx.
Crosstalk‐Free, Stretching‐Insensitive Sensor Based on Arch‐Bridge Architecture for Tactile Mapping with Parallel Addressing Strategy toward Million‐Scale‐Pixels Processing

Published: September 2021

AbstractIn the field of biomimetic electronics, flexible sensors with both high resolution and large size are attracting a lot of attention. However, attempts to increase the number of sensor pixels have been thwarted by the need for complex inner circuits and the resulting interferences with the output. Technological challenges, such as real‐time spatiotemporal mapping and long‐time reliability, must be resolved for large‐scale sensor matrices. This paper reports a simple and robust sensor with an arch‐bridge architecture (ABA) to address these challenges. The device, which consists of an anti‐icing all‐transparent material system, is fabricated by immobilizing ABA ionic arrays on predefined grooves on the substrate. It systematically integrates ABA structure‐designing, resistance‐position‐sensing, and parallel‐addressing logic, allowing for an improvement of three orders of magnitude in the scanning speed (million‐scale pixels) without logical “diagnose confusion.” In addition, it can withstand 100 000 stretching cycles without functional failure. It is also resistant to interferences from stretching. humidity, wet surfaces, and power lines. The proposed strategy is envisaged to serve as a general solution for high‐density, large‐area tactile sensors in various applications.
Plant disease threats to food security in the Northern Great Plains of North America
Authors: Byamukama Emmanuel , Pérez‐Hernández Oscar , Yabwalo Dalitso Nobble 
Published: September 2021

AbstractPlant disease epidemics are responsible for millions of tons of yield loss from crops annually. To provide sufficient nutritious food, feed, fiber, and fuel for a growing world human population on a non‐expanding land resource, yield loss caused by plant pathogens must be minimized. The Northern Great Plains (NGP) region of the United States is a major crop‐producing region, but crop production in this region is threatened by climate variability, new pathogen or pathogen race development, limited in‐field management practices, pathogen synergism, and fungicide resistance in some fungal pathogens. To sustain stable food, feed, fiber, and fuel production from plants, concerted efforts from all stakeholders must be harnessed to develop new varieties that are resistant to plant pathogens and less sensitive to climate variability, promote use of integrated disease management (that incorporates resistant/tolerant varieties, plant disease prediction, and accurate disease diagnosis and assessment), and enhance early detection capabilities of new pathogens/races. Here, we review the current and near‐future likely plant disease epidemic concerns in the NGP of the United States and propose some actions to prevent or lessen the extent of the next plant disease epidemic development.

Curing behavior and properties of epoxy monomers with ethylenediaminetetraacetic dianhydride
Authors: Chennapuram Madhu , Yoshida Yoshiaki , Endo Takeshi 
Published: September 2021

AbstractEthylenediaminetetraacetic acid dianhydride (EDTADA) is a six‐membered cyclic anhydride that contains two tertiary amino groups in the structure. In this work, we have demonstrated that a curing reaction of diglycidyl ether of bisphenol A (DGEBA) and EDTADA proceeded efficiently without any accelerant such as tertiary amine and imidazole. This result proves that EDTADA can act as a self‐sustaining accelerant for the curing reaction of the epoxy monomers. On the other hand, the curing reaction of glycidol with EDTADA proceed successfully via an initiation step owing to the esterification of primary alcohol and anhydride moieties. In this case, we demonstrate that EDTADA also works as an amine catalyst for esterification. Moreover, we have studied the adhesive properties of two types of epoxy resin derived from DGEBA and glycidol with EDTADA.
A stitch in time saves… uncontrollable blood loss
Authors: Seto Arnold H. , Tehrani David M. 
Published: September 2021

Key Points
Suture‐based vascular closure devices are highly effective but can fail because of operator, patient, and procedure factors.
This report from the FDA MAUDE database of device failures included half where such failure led to bleeding or vascular injury requiring surgical or endovascular repair, and death in two patients.
This real‐world data is limited by self‐reporting and an unclear volume of procedures but may help operators understand the failure modes and potential consequences.
MANTA versus Perclose for large‐bore vessel closure: The evidence continues to grow
Authors: Postalian Alexander , Krajcer Zvonimir 
Published: September 2021

Key Points
The MANTA is a new, easy‐to‐use, collagen plug‐based vascular closure device specifically designed for large‐bore arteriotomy closure.
The authors report on their experience comparing the MANTA device with the Perclose ProGlide technique in patients undergoing transcatheter aortic valve replacement.
They found similar rates of success and vascular complications with both devices, suggesting that MANTA is a suitable option for these patients.
It remains to be determined whether one device will emerge as the ideal choice for most patients.
Device cost is a significant barrier to widespread adoption, but price has decreased recently.
Impact of Ultrasound Amplitude on Crystallization of Borax Decahydrate in a Stirred‐Batch Crystallizer
Authors: Čelan Antonija , Milanović Iris , Ćosić Marija , Kuzmanić Nenad 
Published: September 2021

AbstractThe influence of ultrasound amplitude on nucleation kinetics and properties of the final product of borax decahydrate was investigated. Mechanical mixing in a stirred‐batch crystallizer was performed by a straight‐blade turbine (SBT) to ensure a complete suspension of crystals. The obtained results indicated that continuous sonication affects nucleation kinetics, but also the properties of the final product. An increase of the ultrasound amplitude decreases the metastable zone width which ultimately reflects on the final crystal size. Even though the mean crystal size was larger in the non‐sonicated system, it seems that the application of ultrasound shifts the crystal size distribution from bimodal to monomodal. But the shift comes at the cost of a substantial increase in power consumption.
