Race, Revisionism, Ethnic Boundaries, and Japanese American Internment
Authors: Kurashige Lon 
Published: May 2021

Abstract
Recognizing the centrality of race in US immigration and ethnic history—what is known as the field’s “racial turn”—has been advocated, applauded, and globalized; but it has yet to be examined from a theoretical perspective. To better understand the appeal and limitations of the field’s race-centered analysis, historians can profit from studying the contemporary development of race theory, as well as the revisionism against it. There is a vigorous debate among social scientists about the significance of race. This article addresses this debate, especially from the revisionist side. In so doing, it highlights revisionist Andreas Wimmer’s model of ethnic boundary making, and explores its insights for the study of Japanese American internment during World War II.
Forbedringspotensial i den norske fødselsomsorgen
Authors: Skogheim Gry , Lundgren Ingela 
Published: May 2021

Tema for denne artikkelen er medikalisering i norsk fødselsomsorg. I teksten beskriver og analyserer vi noen av faktorene som er knyttet til medikalisering. Til tross for at norsk fødselsomsorg har svært gode medisinske/fysiske utfallsmål for kvinner og barn, er det behov for forbedringer. Norge, som mange andre høy-inntektsland, har for mange keisersnitt og andre fødselsintervensjoner. Medikalisering ser også ut til å føre med seg sentralisering, samt dominans over andre modeller for fødselsomsorg og helsefremmende perspektiv. Til tross for at et av målene i den norske tjenesten er en demedikalisert fødselsomsorg (på ulike nivå i helsetjenesten), har økende grad av sentralisering funnet sted de siste tiår; f.eks. har antallet jordmorledede fødeenheter/fødestuer blitt redusert. Å inkludere en kvinnesentrert modell i tjenesten kan styrke at kvinnenes behov blir møtt. I en kvinnesentrert modell er f.eks. kvinners erfaringer, deres delaktige i omsorgen de tilbys og relasjonen mellom kvinnen og jordmor/helsepersonell, svært viktig. I tillegg kan anvendelse av salutogenese-teorien bidra til å styrke fødselsomsorgens helsefremmende perspektiv.

Potential for improvement in the Norwegian childbirth model
In this paper some aspects of medicalization in the Norwegian childbirth context are described and analysed. Despite having very good medical outcomes for women and babies, there is a need for improvement. As in many other high-income countries, there are too many Caesarean sections and interventions during births. Medicalized care tends to lead to centralisation of the care and dominate over other models of care and health promoting aspects. Even if the goal of the Norwegian model is de-medicalised maternity care on different levels, centralisation have occurred during the last decades. For example midwifery-led units has decreased in numbers. Woman-centred care is a model of care that can meet what is lacking by focusing at women´s experiences, women´s participation and involvement in the care and the relationship between the woman and the care-giver. Furthermore, salutogenesis is a health promoting perspective that could contribute to maternity care.
Impact of Climate Change on Pulse Production and it’s Mitigation Strategies
Authors: Bera Anurag 
Published: May 2021

Climate change has emerged as one of the major environmental issue due to it’s subsequent effect on food production and food security. The changing climate over the years posing a major impact on rainfed crops including pulses. India, the largest producer of Pulses over the world with 25% share in global pulse production are largely dependent on pulses that grows in rainfed areas. As a result, climate change are predicted to be more pronounced in these crops. Increasing concentration of greenhouse gases like CO2 act as catalyst on enhancing global temperature which in term affecting heat-sensitive Pulse crops. Such a scenario emanating from the climate change presents a veritable challenge to the food and feed economy [1].
Pulses are one of the most important food crops which serve as main source of vegetable protein in human diet. In the recent scenario, we are observing a declining growth rate in pulse production. Inadequate and erratic rainfall, abrupt rise in temperature, untimely drought are posing threat to pulse production. Shift in monsoon causes delayed sowing of kharif crops as it’s consequence sowing of pulse crops in rabi season also get delayed. Delayed sown crops face terminal heat during it’s phenological growth which reduces it’s potential yield, on the other hand untimely rainfall in it’s reproductive growth period during the month of Feb-Mar reduces the yield drastically [2]. Other problems like salinity, waterlogging also act as menace in pulse cultivation. Last but not the least, changing climate often facilitates pest-disease infestation, weed emergence which can cause a huge reduction in crop yield.
To meet these emerging challenges of climate change, there is an urgent need of developing proper mitigation strategies combining with Agronomic and breeding approaches. Intervention of Government policy and crop insurance scheme along with proper alleviation strategies will definitely contribute in stabilization of yield of pulse crops in near future.

Published: May 2021

Artemether/lumefantrine/tinidazole (A/L/T) has shown additive antiplasmodial activity; therefore its safety assessment is imperative. This study examined its hepatotoxic effect on healthy and diseased mice. Fifty four Swiss albino mice of n=6 were used. The mice were diseased with Plasmodium berghei ( ) and treated with T (28.6 mg/kg), A/L (2.3/13.7mg/kg) and A/L/T for 4 days, respectively. Healthy mice were treated with T (28.6 mg/kg), A/L (2.3/13.7mg/kg) and A/L/T for 28 days, respectively. After drug treatment; the mice were weighed and anesthetized. Liver samples were excised, weighed and evaluated for oxidative stress indices and histology. Blood samples were assessed for serum liver function indices. Treatment with T, A/L and A/L/T produced no significant (p>0.05) effects on all evaluated parameters in parasitized mice when compared to control. Significant decrease in body weight with significant increase in liver weight occurred in healthy mice treated with A/L (p<0.05) and A/L/T (p<0.01) when compared to control. Impaired liver function characterized by significantly increased serum aminotranferases, alkaline phosphatase, lactate dehydrogenase, gamma-glutamyl transferase, and bilirubin levels with significantly decreased total protein and albumin levels occurred in healthy mice treated with T (p<0.05), A/L (p<0.01) and A/L/T (p<0.001) when compared to control. Significantly decreased glutathione peroxidase, superoxide dismutase, glutathione, and catalase levels with significantly increased malondialdehyde levels occurred in healthy mice treated with T (p<0.05), A/L (p<0.01) and A/L/T (p<0.001) when compared to control. A/L/T caused hepatocyte necrosis in healthy mice. The use of A/L/T for malaria treatment seems safe on the liver, but may impair liver function with prolonged use.

Rapid changes are occurring in our global ecosystem, and stresses on human well-being, such as climate regulation and food production, are increasing, soil is a critical component of agriculture. The project aims to use Data Mining (DM) classification techniques to predict soil data. Analysis DM classification strategies such as k-Nearest-Neighbors (k-NN), Random-Forest (RF), Decision-Tree (DT) and Naïve-Bayes (NB) are used to predict soil type. These classifier algorithms are used to extract information from soil data. The main purpose of using these classifiers is to find the optimal machine learning classifier in the soil classification. in this paper we are applying some algorithms of DM and machine learning on the data set that we collected by using Weka program, then we compare the experimental result with other papers that worked like our work. According to the experimental results, the highest accuracy is k-NN has of 84 % when compared to the NB (69.23%), DT and RF (53.85 %). As a result, it outperforms the other classifiers. The findings imply that k-NN could be useful for accurate soil type classification in the agricultural domain.

Colorectal cancer (CRC) is one of the most common cancer types globally with a 5‐year survival rate of < 50% in China. Aberrant DNA methylation is one of the hallmarks of tumor initiation, progression, and metastasis. Here, we investigated the clinical performance of two differentially methylated regions (DMRs) in SDC2 CpG islands for the detection of CRC. A sliding window technique was used to identify the DMRs, and methylation‐specific PCR assay was used to assess the DMRs in 198 CRC samples and 54 normal controls. Two DMRs (DMR2 and DMR5) were identified using The Cancer Genome Atlas (TCGA) data, and the hypermethylation of DMR2 and DMR5 was detected in 90.91% (180/198) and 89.90% (178/198) of CRC samples, respectively. When combining DMR2 and DMR5, the sensitivity for CRC detection was 94.4% higher than that of DMR2 or DMR5 alone. Based on the above results, we propose using DMR2 and DMR5 as a sensitive biomarker to detect CRC.

AbstractGraphene quantum dots (GQDs) have attracted great attention as next‐generation luminescent nanomaterials due to the advantages of a low‐cost process, low toxicity, and unique photoluminescence (PL). However, in the solid‐state, the strong π−π stacking interactions between the basal planes of GQDs lead to aggregation‐caused PL quenching (ACQ), which impedes practical application to light‐emitting devices. Here, surface functionalized GQDs (F‐GQDs) by polyhedral oligomeric silsesquioxane (POSS), poly(ethylene glycol) (PEG), and hexadecylamine (HDA) to reduce π−π stacking‐induced ACQ is presented. The POSS‐, PEG‐, and HDA‐functionalized GQDs show a significant enhancement in PL intensity compared to bare GQDs by 9.5‐, 9.0‐, and 5.6‐fold in spin‐coated film form and by 8.3‐, 7.2‐, and 3.4‐fold in drop‐casted film form, respectively. Experimental results and molecular dynamics simulations indicate that steric hindrance of the functionalization agent contributes to reducing the π−π stacking between adjacent GQDs and thereby enabling quenching‐resistant PL in the solid‐state. Moreover, the GQD‐based white light‐emitting diodes fabricated by mounting HDA‐GQDs on a UV‐LED chip exhibits efficient down‐conversion for white light emission with a high color rendering index of 86.2 and a correlated‐color temperature of 5612 K at Commission Internationale de l'Éclairage coordinates of (0.333, 0.359).
Polarons and Charge Localization in Metal‐Halide Semiconductors for Photovoltaic and Light‐Emitting Devices
Authors: Buizza Leonardo R. V. , Herz Laura M. 
Published: May 2021

AbstractMetal‐halide semiconductors have shown excellent performance in optoelectronic applications such as solar cells, light‐emitting diodes, and detectors. In this review the role of charge–lattice interactions and polaron formation in a wide range of these promising materials, including perovskites, double perovskites, Ruddlesden–Popper layered perovskites, nanocrystals, vacancy‐ordered, and other novel structures, is summarized. The formation of Fröhlich‐type “large” polarons in archetypal bulk metal‐halide ABX3 perovskites and its dependence on A‐cation, B‐metal, and X‐halide composition, which is now relatively well understood, are discussed. It is found that, for nanostructured and novel metal‐halide materials, a larger variation in the strengths of polaronic effects is reported across the literature, potentially deriving from variations in potential barriers and the presence of interfaces at which lattice relaxation may be enhanced. Such findings are further discussed in the context of different experimental approaches used to explore polaronic effects, cautioning that firm conclusions are often hampered by the presence of alternate processes and interactions giving rise to similar experimental signatures. Overall, a complete understanding of polaronic effects will prove essential given their direct influence on optoelectronic properties such as charge‐carrier mobilities and emission spectra, which are critical to the performance of energy and optoelectronic applications.
Underwater Communication and Optical Camouflage Ionogels
Authors: Yu Zhenchuan , Wu Peiyi 
Published: May 2021

AbstractMarine animals, such as leptocephalus and jellyfish, can sense external stimuli and achieve optical camouflage in the aquatic environment. Fabricating an intelligent soft sensor that can mimic the capabilities of transparent marine animals and function underwater can enable transformative applications in various novel fields. However, previously reported soft sensors struggle to meet the requirements of adhesion, self‐healing ability, optical transparency, and stable conductivity in the aquatic environment. Herein, high‐performance ionogels by virtue of ion–dipole and ion–ion interactions between fluorine‐rich poly(ionic liquid) and ionic liquid are designed. The hydrophobic dynamic viscoelastic networks provide excellent properties for ionogels, including optical transparency, adjustable mechanical properties, underwater self‐healing ability, underwater adhesiveness, conductivity, and 3D printability. A mechanically compliant and visually invisible underwater soft sensor based on ionogel is developed. This sensor can achieve optical camouflage, human‐body‐motion detection, and barrier‐free communication in the aquatic environment. A novel contactless sensing mechanism based on changing the electron transfer pathway is proposed. Several interesting functions, such as detection of water environment changes, recognition of objects, delivery of information, and even identification of human standing posture can be realized. Importantly, the ionogel sensor can avoid fatigue and physical damage in the sensing process.

AbstractLiquids are traditionally handled and stored in solid vessels. Solid walls are not functional, adaptive, or self‐repairing, and are difficult to remove and re‐form. Liquid walls can overcome these limitations, but cannot form free‐standing 3D walls. Herein, a liquid analogue of a well, termed a “liquid well” is introduced. Water tethered to a surface with hydrophobic–hydrophilic core–shell patterns forms stable liquid walls capable of containing another immiscible fluid, similar to fluid confinement by solid walls. Liquid wells with different liquids, volumes, and shapes are prepared and investigated by confocal and Raman microscopy. The confinement of various low‐surface‐tension liquids (LSTLs) on surfaces by liquid wells can compete with or be complementary to existing confinement strategies using perfluorinated surfaces, for example, in terms of the shape and height of the confined LSTLs. Liquid wells show unique properties arising from their liquid aggregate state: they are self‐healing, dynamic, and functional, that is, not restricted to a passive confining role. Water walls can be easily removed and re‐formed, making them interesting as sacrificial templates. This is demonstrated in a process termed water‐templated polymerization (WTP). Numerical phase‐field model simulations are performed to scrutinize the conditions required for the formation of stable liquid wells.

Published: May 2021

AbstractCell culture experiments often suffer from limited commercial availability of laboratory‐scale bioreactors, which allow experiments to be conducted under flow conditions and additional online monitoring techniques. A novel 3D‐printed bioreactor with a homogeneously distributed flow field enabling epithelial cell culture experiments and online barrier monitoring by integrated electrodes through electrical impedance spectroscopy (EIS) is presented. Transparent and conductive indium tin oxide glass as current‐injecting electrodes allows direct visualization of the cells, while measuring EIS simultaneously. The bioreactor's design considers the importance of a homogeneous electric field by placing the voltage pick‐up electrodes in the electrical field. The device's functionality is demonstrated by the cultivation of the epithelial cell line Caco‐2 under continuous flow and monitoring of the cell layer by online EIS. The collected EIS data were fitted by an equivalent electric circuit, resulting in the cell layer's resistance and capacitance. This data is used to monitor the cell layer's reaction to ethylene glycol‐bis‐(2‐aminoethyl ether)‐N,N,N′,N′‐tetraacetic acid and forskolin. These two model substances show the power of impedance spectroscopy as a non‐invasive way to characterize cell barriers. In addition, the bioreactor design is available as a print‐ready file in the Appendix, enabling its use for other scientific institutions.
