Narrowband transmission filters based on resonant waveguide gratings and conformal dielectric-plasmonic coatings
Authors: Gallinet Benjamin , Quaranta Giorgio , Schneider Christian 
Published: November 2020

Abstract
Nanostructured filter arrays on image sensors are promising for miniature spectrometers and spectral imagers. In this work, we report on resonant waveguide gratings fabricated by UV nanoimprint lithography and conformal dielectric-plasmonic coatings. Optical measurements in accordance with numerical simulations report on a resonance bandwidth of 20 nm in transmission in the visible range. The impact of cladding thickness and filter lateral size on the resonance properties is investigated with the help of numerical calculations. Finally, it is shown that the proposed geometry based on conformal coatings has a very efficient blocking rate compared to other nanostructured filter approaches.

Published: November 2020

AbstractCellular biomass of microorganisms can be effectively used in the treatment of waste from various branches of the agro-food industry. Urbanization processes and economic development, which have been intensifying in recent decades, lead to the degradation of the natural environment. In the first half of the 20th century, problems related to waste management were not as serious and challenging as they are today. The present situation forces the use of modern technologies and the creation of innovative solutions for environmental protection. Waste of industrial origin are difficult to recycle and require a high financial outlay, while the organic waste of animal and plant origins, such as potato wastewater, whey, lignin, and cellulose, is dominant. In this article, we describe the possibilities of using microorganisms for the utilization of various waste products. A solution to reduce the costs of waste disposal is the use of yeast biomass. Management of waste products using yeast biomass has made it possible to generate new metabolites, such as β-glucans, vitamins, carotenoids, and enzymes, which have a wide range of industrial applications. Exploration and discovery of new areas of applications of yeast, fungal, and bacteria cells can lead to an increase in their effective use in many fields of biotechnology.

Published: November 2020

Abstract
Agar is a strongly gelling polysaccharide extracted from gracilarioids, which is processed through conventional alkaline pre-treatment and chemical bleaching. However, the use of chemical bleaching agents has associated health risks to humans and the environment. The aim of the present study was to determine the effects of photo-bleaching in combination with NaOH pre-treatments at 5, 10 and 15% concentrations on the physico-chemical properties of agar extracted from Gracilariopsis heteroclada. The results highlighted that the gel strength of photo-bleached agar extracts PBA-15 (1822.00 g cm−2), PBA-10 (1465.60 g cm−2), and PBA-5 (1067.70 g cm−2) were significantly higher than in either a commercially sourced agar reference sample (756.20 g cm−2) or a chemically bleached agar (390.94 g cm−2). The physico-chemical properties of PBA extracts fell within the acceptable limits of food-grade agar. Photo-bleached agar extracts (PBA-5, PBA-10, PBA-15) also exhibited a higher lightness (L*) and whiteness index (WI) which makes these agars ideal for microbiological use. This study demonstrated that photo-bleaching by solar irradiation improved the physico-chemical properties of agar from G. heteroclada without the use of a chemical bleaching agent.
Topology of the mesoscale connectome of the mouse brain
Authors: Grange Pascal 
Published: November 2020

Abstract
The wiring diagram of the mouse brain has recently been mapped at a mesoscopic scale in the Allen Mouse Brain Connectivity Atlas. Axonal projections from brain regions were traced using green fluoresent proteins. The resulting data were registered to a common three-dimensional reference space. They yielded a matrix of connection strengths between 213 brain regions. Global features such as closed loops formed by connections of similar intensity can be inferred using tools from persistent homology. We map the wiring diagram of the mouse brain to a simplicial complex (filtered by connection strengths). We work out generators of the first homology group. Some regions, including nucleus accumbens, are connected to the entire brain by loops, whereas no region has non-zero connection strength to all brain regions. Thousands of loops go through the isocortex, the striatum and the thalamus. On the other hand, medulla is the only major brain compartment that contains more than 100 loops.
Complex Lagrangians in a hyperKähler manifold and the relative Albanese
Authors: Biswas Indranil , Gómez Tomás L. , Oliveira André 
Published: November 2020

AbstractLet M be the moduli space of complex Lagrangian submanifolds of a hyperKähler manifold X, and let ω̄ : 𝒜̂ → M be the relative Albanese over M. We prove that 𝒜̂ has a natural holomorphic symplectic structure. The projection ω̄ defines a completely integrable structure on the symplectic manifold 𝒜̂. In particular, the fibers of ω̄ are complex Lagrangians with respect to the symplectic form on 𝒜̂. We also prove analogous results for the relative Picard over M.
Digital image steganography and steganalysis: A journey of the past three decades
Authors: Sahu Aditya Kumar , Sahu Monalisa 
Published: November 2020

AbstractSteganography is the science and art of covert communication. Conversely, steganalysis is the study of uncovering the steganographic process. The evolution of steganography has been paralleled by the development of steganalysis. In this game of hide and seek, the two player’s steganography and steganalysis always want to break the other down. Over the past three decades, research has produced a plethora of remarkable image steganography techniques (ISTs). The major challenge for most of these ISTs is to achieve a fair balance between the metrics such as high hiding capacity (HC), better imperceptibility, and improved security. This study aims to present an exhaustive scrutiny of various ISTs from the classical to recent developments in the spatial domain, with respect to various image steganographic metrics. Further, the current status, recent developments, open challenges, and promising directions in this field are also highlighted.

Published: November 2020

Abstract
The conversion of CO2 to methanol holds great promise, as it offers a pathway to reduce CO2 level in the atmosphere and also produce valuable components. In this study, a typical methanol synthesis plant for CO2 conversion was numerically modeled. Effect of fresh feed to plant parameters (i.e., pressure and CO2 concentration) as well as the influence of recycle ratio on the reactor performance was investigated. Hence, all essential equipment, including compressor, mixer, heat exchanger, reactor, and liquid–vapor separator were considered in the model. Then, at the best operating conditions, thermal behavior and components distribution along the length and radius of the reactor were predicted. Finally, the effect of inert gases was investigated in the methanol production process and the results were compared with the conventional route (CR), which uses natural gas for methanol synthesis. The results revealed that in the absence of inert gases and by employing a recycle stream in the process, CO2 hydrogenation leads to 13 ton/day production of methanol more than CR. While in the feedstock containing 20% inert gases, which is closer to the realistic case, methanol production rate is 45 ton/day lower than CR. These findings prospect a promising approach for the production of green methanol from carbon dioxide and hydrogen.
Little Womentravelling to Scandinavia
Authors: Egeland Marianne 
Published: November 2020

AbstractThe publishing history of an American classic in Sweden, Denmark and Norway illustrates how literature travels between countries and how translated books become integrated in the new national cultures. Louisa May Alcott’sLittle Women(1868) still figures on lists of the most cherished, translated and influential children’s books. Sweden can probably boast of the longest translation history of all, starting in 1871, the latest translation appearing in 2016. The Danish material more or less replicates the Swedish, whereas data mining of the stacks of Norway’s National Library demonstrates to what extent a national culture is affected by translated foreign literary impulses and the wealth of sources in which canonized authors may leave a mark. “Little Womentravelling to Scandinavia” addresses why Alcott’s book did so well there, why it appealed to readers, and in what circumstances it was read.

Published: November 2020

Abstract
A phosphoramidate flame retardant (dimethyl N,N-bis(2-hydroxyletheyl)phosphoramidate, DMBHP) was synthesized and applied to cotton fabrics for enhancing the flame retardancy. The structure of DMBHP was characterized by FT-IR and NMR. The flame retardancy and combustion behavior of the treated cotton fabrics were evaluated using the vertical flammability test (VFT), limiting oxygen index (LOI), and the cone calorimetric test. Moreover, to further analyze the flame retardant action of DMBHP in cotton fabrics, thermal degradability of the treated fabrics, as well as the chemical structure, surface morphology, and element contents of the char residue of the DMBHP-treated fabrics were also evaluated. The results show that, after treating with DMBHP, the cotton fabrics acquired a LOI value from 18.1 to 31.1 with the concentration increasing to 30% and self-extinguished in VFT tests when treated with up to 15% DMBHP. Besides, the total heat release and the peak heat release rate of DMBHP (30%)-treated fabric decreased obviously compared with the pure cotton along with more residue retained. TG, SEM, and EDS results of treated cotton fabric and the corresponding residue after burning showed that DMBHP has the capability of enhancing char formation. In addition, DMBHP will confer cotton fabrics a certain durability against washing with the help of 1,2,3,4-butanetetracarboxylic acid (BTCA) and citric acid (CA).

Abstract
Emerging bacterial resistance is causing widespread problems for the treatment of various infections. Therefore, the search for antimicrobials is a never-ending task. Hydrazones and quinolines possess a wide variety of biological activities. Herewith, eleven quinoline hydrazone derivatives have been designed, synthesized, characterized and evaluated for their antibacterial activity and antitubercular potential against Mtb WT H37Rv. Compounds QH-02, QH-04 and QH-05 were found to be promising compounds with an MIC value of 4 μg/mL against Mtb WT H37Rv. Compounds QH-02, QH-04, QH-05, and QH-11 were also found to be active against bacterial strains including Acinetobacter baumanii, Escherichia coli and Staphylococcus aureus. Further, we have carried out experiments to confirm the cytotoxicity of the active compounds and found them to be non-toxic.

Authors: Ağırtaş Mehmet Salih 
Published: November 2020

Abstract
In this present study, a new axially bis-4-tritylphenoxy substituted silicon phthalocyanine compound was synthesized and characterized using infrared, mass, electronic absorption and nuclear magnetic resonance spectroscopy. Fluorescence and absorption spectra studies of the disubstituted silicon phthalocyanine complex were conducted on the chloroform, dimethyl formamide, dimethyl sulfoxide and tetrahydrofuran solutions. The findings of the fluorescence studies demonstrated that the compound has fluorescence spectra in the different solvents. The effects of the substitution with axially bis-4-tritylphenoxy functionalized groups on these parameters were also compared with the previously synthesized axially disubstituted silicon phthalocyanines. These results proved that the compound has different fluorescence properties in the different solvents.

Abstract
This study applied synchrotron radiation XRD to analyze the mechanical behavior of cellulose microfibrils in wood containing annual rings (thickness: 5 mm), for different layers of the secondary cell wall, under uniaxial load. Cellulose in S2 and in S1 and S3 layers were analyzed respectively, and the data were used to investigate for deformation behavior in the lattice spacing (d
004). As a result, the mechanical behavior of cellulose sometimes differed from the behavior of bulk wood. The rigidity of cellulose in the S2 layer was larger than in S1 and S3 layers under both of tensile and compressive loads. However, once standardized with respect to estimated cellulose amount, this standardized rigidity was comparable across all layers and loading conditions. Variation in microfibril angle (MFA) and lattice spacing (d
004) of cellulose barely changed at all under compressive load. Under tensile loads, there were both of positive and negative changes in MFA variation in both S2 layer and S1 and S3 layers, while d
004 variation had little changes in almost all cases.

Abstract
Urinary incontinence is a common health problem that impacts the quality of life of women at different ages. Its physiopathology is not unequivocal, and it is necessary to consider the stress urinary incontinence (SUI), the overactive bladder syndrome and the mixed incontinence (MUI). According to the type of incontinence, its impact on the quality of life and age of the patients, therapeutic strategies are currently summarized in physiotherapy, surgery and drug treatments. We already know the benefit/risk ratio of each of these strategies. Our objective is to evaluate the potential effectiveness and safety of the VEL, an innovative vaginal laser technique (VEL – Vaginal Erbium Laser, erbium yttrium-aluminum-garnet -Er: YAG) a non-invasive laser proposed as a treatment for SUI, overactive bladder syndrome and MUI. The mechanisms of action of lasers are discussed in general and those of VEL in particular with the description of the Smooth® mode. To do this, we have collected the 21 published studies including the first randomized vs. placebo and two pilot studies of intra-urethral VEL. In conclusion: VEL procedures already have their place between the rehabilitation of the perineal floor and surgery. Further properly sized, randomized studies are needed to evaluate the laser treatments in comparison with other therapies, as well as to assess the duration of the therapeutic effects and the safety of repeated applications.

Published: November 2020

Abstract

Purpose
The purpose of this study was to explore the differences between youths with a sibling affected by a chronic condition or a disability (SCCD) and their peers with healthy siblings.

Method
Using data from the second wave of GenerationFRee study, we compared adolescents from each gender with healthy siblings to adolescents with SCDD on demographical, familial, internalizing and externalizing behavior variables. Subsequently we repeated the analysis excluding from each group adolescents who suffered from a chronic condition or disability themselves.

Results
At the bivariate and multivariate level, among those with SCDD, healthy females reported more somatic symptoms, healthy males more violent behaviors, and both genders lived more often in non-intact families. When considering both healthy and unhealthy adolescents, at bivariate analysis female adolescents with SCDD were more likely to have a poorer relationship to their mother, to be unhealthy, to smoke, to be at risk for disordered eating and to report somatic symptoms. At multivariate level, only the association with SCDD and smoking remained. Male adolescents with SCDD, at both bivariate and multivariate analyses, were more likely to be unhealthy and to live in larger and non-intact families.

Conclusion
Healthy adolescents with an SCDD are more at risk of somatic symptoms and violent behaviors than their peers with healthy siblings. Health professionals in contact with adolescents should always consider them with a systemic approach. Parents should be informed about the potential effect on the siblings of a CDD child, but also reassured, as adolescents with SCDD are not different from their peers with healthy siblings.

Published: November 2020

Abstract

Background
breakfast elimination as well as consumption of low-value snacks is ever increasing among adolescents. This study sought to explain the dimensions of social support for breakfast and healthy snacks among students.

Methods
A qualitative research was conducted in Isfahan, Tehran, and Khorramabad, Iran high schools in 2017–18. Data were obtained from five focus group discussions and 35 in-depth interviews as well as semi-structured interviews with students of both sex, parents and school authorities. The data simultaneously analyzed using conventional content analysis in three stages including preparation, organization, and reporting. Prolonged engagement, maximum variation of sampling and member check were the enrichment factors of the research.

Results
Three main categories emerged. First, family supports with sub- categories of family in the school programs as well as mother-sponsored support and family life patterns. Second, school supports with sub- categories of instrumental and informational support. And third, support of other community organizations with sub- categories of intra-department coordination and mass media.

Conclusion
The concepts emerging in the present study develop multilevel ecological strategies to promote nutritional health including family, school, and community organizations such as school renovations, municipalities, police, education, and mass media to promote healthy breakfast and snack behavior are applicable for students.

Published: November 2020

Abstract
Geopolymer has been presented as new evolution in the concrete technology world, where cementitious materials such as ceramic powder and Slag have been replaced by high percentages of cement used in construction. Thus, the activation of such materials was performed by highly alkaline solutions in order to be acted as a binder in the mix. Therefore, the selection of suitable ingredients proportion of geopolymer mortar to achieve desired strength at required workability has been intended in this study. The experimental Program has been implemented for the preparation of geopolymer mortar mixes. The concentration of sodium hydroxide solution was kept constant in the order of 12 M throughout the experiment. The ratio of Water to geopolymer binder ratio was 0.35, alkaline solution-to- cementitiuos materials ratio was 0.30 and sodium silicate-to-sodium hydroxide ratio was 1.85 by mass. Workability of geopolymer mortar was measured by flow table apparatus and cubes of 50 mm side were cast and tested for compressive strength after 28 days of normal water curing. The study concludes that the combination of ceramic powder and Slag up to 40% (by weight), in the total binder material, can be used for developing the geopolymer mortar. Continuously, the use of 1% steel fibers or 1% steel fiber with 0.5% sisal fibers promotes the level of cement replacement by such cementitous materials (slag and ceramic powder) up to 60%.
