Surfactant-free oil-in-oil emulsion-templating of polyimide aerogel foams
Authors: Farrell Erin , Jana Sadhan C. 
Published: July 2022

Abstract
A surfactant-free oil-in-oil emulsion-templating method is presented for fabrication of monolithic polyimide aerogel foams using monomer systems that produce fast sol–gel transition. An aerogel foam is a high porosity (∼90%) material with coexisting meso- and macropores inherent to aerogels with externally introduced micrometer size open cells (macrovoids) that are reminiscent of foams. The macrovoids are introduced in polyimide sol using surfactant-free emulsion-templating of droplets of an immiscible liquid that are stabilized against coalescence by fast sol–gel transition. Three immiscible liquids – cyclohexane, n-heptane, and silicone oil – are considered in this work for surfactant-free emulsion-templating. The aerogel foam monoliths, recovered by supercritical drying, exhibit smaller size macrovoids when n-heptane and cyclohexane are used as emulsion-templating liquid, while the overall porosity and the bulk density show weak dependence on the emulsion-templating liquid.
Geotechnical characterization of sustainable geopolymer improved soil
Authors: Al-Rkaby Alaa H. J. , Odeh Noor Aamer , Sabih Ahmed , Odah Haider 
Published: July 2022

Abstract
Geopolymer (GP) has recently emerged as a novel and environmental friendly alternative to conventional soil stabilization products like lime and Ordinary Portland Cement (OPC), which adversely affect the environment. This article emphasizes GPs produced from high calcium class C fly ash (CFA) and an alkali activator comprising sodium hydroxide and sodium silicate solution for sand stabilization. The experimental program includes a series of unconfined compressive strength (UCS), flexural strength, tensile strength, and microstructural analyses using scanning electron microscopy. Results revealed that UCS, flexural strength, and tensile strength of GP-treated soil were in the range of 2–10, 0.5–2.0, and 0.4–1.2 MPa, respectively (depending on the ratio of fly ash and activator). These strengths were even higher than those of cement-stabilized soil. The microstructural analysis revealed that the formation of dense calcium–sodium alumina–silicate hydrated gel (C, N–A–S–H) is the reason for strength improvement. According to the findings of this study, using a CFA-GP binder for soil improvement is a viable alternative to OPC in geotechnical applications.

Published: July 2022

Abstract
The multipole expansion of a nano-photonic structure’s electromagnetic response is a versatile tool to interpret optical effects in nano-optics, but it only gives access to the modes that are excited by a specific illumination. In particular the study of various illuminations requires multiple, costly numerical simulations. Here we present a formalism we call “generalized polarizabilities”, in which we combine the recently developed exact multipole decomposition [Alaee et al., Opt. Comms. 407, 17–21 (2018)] with the concept of a generalized field propagator. After an initial computation step, our approach allows to instantaneously obtain the exact multipole decomposition for any illumination. Most importantly, since all possible illuminations are included in the generalized polarizabilities, our formalism allows to calculate the total density of multipole modes, regardless of a specific illumination, which is not possible with the conventional multipole expansion. Finally, our approach directly provides the optimum illumination field distributions that maximally couple to specific multipole modes. The formalism will be very useful for various applications in nano-optics like illumination-field engineering, or meta-atom design e.g. for Huygens metasurfaces. We provide a numerical open source implementation compatible with the pyGDM python package.

Authors: Su Wei , Sun Huibin , Wang Yiyun , Su Tian 
Published: July 2022

Abstract
In this article, the bond performance of recycled coarse aggregate concrete with rebar after freeze–thaw cycles is analyzed by the ABAQUS finite element method. The result shows that the finite element simulation value of the ultimate bond strength of recycled aggregate concrete specimens is in good agreement with the experimental value, while the agreement between the finite element simulation value of the peak bond slip of recycled aggregate concrete specimens and the experimental value is low; the bond strength between rebar and recycled aggregate concrete increased with the increase of concrete strength and concrete cover depth; the calculation formula for the bond strength between recycled aggregate concrete specimens with different concrete strengths and different concrete cover depth after freeze and thaw cycles are obtained.

Published: July 2022

The objective of this study was to systematically review the literature on the human microbiome in association with endometriosis. PubMed/Medline, Cochrane, and Embase databases were searched for literature published from 1986 to August 2021. All human studies that assessed the microbiome using 16S rRNA sequencing or shotgun sequencing in women with endometriosis were included. Two reviewers independently abstracted data from the selected articles into tables. To assess the quality of included studies, the National Institutes of Health Study Quality Assessment Tools were utilized. This review included 12 case–control studies. Included studies compared the microbiome from various anatomical sources (fecal, vaginal, cervical, peritoneal, endometrial, and intra-lesional) between patients with endometriosis and a heterogeneous set of control patients. Study quality ranged from poor to good, with 8 of 12 studies rated fair. Multiple studies reported a different distribution of bacteria among women with endometriosis across anatomical sites, but the results were highly heterogeneous. Pseudomonas was overrepresented in peritoneal fluid among women with endometriosis across multiple studies but was also observed to be increased in vaginal, endometrial, and intra-lesional samples. Among bacteria noted across different anatomical samples, Gardnerella was found to be increased in cervical but decreased in endometrial, fecal, and vaginal samples of patients with endometriosis, while Atopium was found to be decreased in vaginal and cervical samples from patients with endometriosis. Sphingobium was found to be increased in vagina, endometrium, and peritoneal fluid from patients with endometriosis. Streptococcus was found to be increased in peritoneal, endometrial, and cervical samples from women with endometriosis. Microbiomal comparisons stratified by endometriosis stage or site of endometriosis involvement were limited and highly heterogeneous.

Lay summary
The microbiome, a group of bacteria found in a particular place in the body, has been shown to vary when patients have some diseases, such as cancer or inflammatory bowel disease. Less is known about the microbiome in patients with endometriosis. This review looked at existing studies comparing the bacteria found in patients with endometriosis and others without. Twelve studies were found that assessed the bacteria from swabs collected from different places, including the vagina, cervix, endometrium, peritoneum, feces, and endometriosis lesions themselves. Most of the studies found higher or lower levels of specific bacteria at each of these places, but the findings were often inconsistent. The findings were probably limited by the small numbers of patients involved and variations in the groups studied. More research is needed to find out which bacteria are over- and underrepresented in patients with endometriosis and where they are found.

Published: July 2022

Malignant broncho-pulmonary tumors are the principal cause of the paraneoplastic nephrotic syndrome. These tumors are most often small cell or squamous bronchial carcinomas. In 75% of cases, the nephrotic syndrome is due to membranous glomerulonephritis. We report the case of a 67 years old patient, a chronic tobacco user, followed since June 2019 for a nephrotic syndrome caused by extra-membranous glomerulonephritis. A chest computed tomography revealed a mass of the left lower lobe. Trans-parietal biopsy of this process revealed a squamous bronchial carcinoma. PET scan detected no other fixations. The proteinemia was at 39g/l with albuminemia at 14 g/l. Surgical resection was then indicated and the patient underwent a left lower lobectomy with radical lymph adenectomy. Outcomes were simple with complete resolution of paraneoplastic nephrotic syndrome.

Abstract
Non-alcoholic fatty liver disease is one of the most common chronic liver diseases with unclarified pathomechanism and without evidence-proven therapy. Dietary polyphenols, targeting oxidative stress, are at the center of investigations. Our aim was to examine the effects of a polyphenol rich extract on metal element homeostasis and transmethylation ability in non-alcoholic fatty liver model. A ten-day rat model was used (control group, hyperlipidemic group with fat-rich diet, hyperlipidemic group with fat-rich diet and polyphenol supplementation, N = 8 in each group). The hyperlipidemic diet increased the concentration of the majority of the elements with significantly higher contents of B, Co, Cu, Fe, Mg, Mn, Na, Ni, P, Se, Si, and Zn in the liver. Further elevation of Al, Pb, and Sn concentrations could be observed in polyphenol supplemented animals. The polyphenol supplement unexpectedly decreased the transmethylation ability of the liver (132.00 vs. 114.15 vs. 92.25 HCHO μg g−1) further. The results emphasize the possible role of altered metal and non-metal element concentrations and decreased transmethylation ability in the pathomechanism of fatty liver disease. Dietary supplementation with natural compounds may have undesirable effect as well, there is the necessity to improve the efficacy of polyphenol formulations because of their low oral bioavailability.

Authors: Briken Peer , Turner Daniel 
Published: July 2022

Abstract
This paper comments three recent publications in the Journal of Behavioral Addictions (Brand et al., 2022; Gola et al., 2022; Sassover & Weinstein, 2022). It shortly discusses (1) the role of researcher biases and the significance of the naming of a disorder (here “sexual addiction” and “pornography use disorder”) for stigma and treatment, (2) the development and course of CSBD and its significance for research results, (3) the role of “Sexual” in CSBD. The paper concludes that the guidelines for CSBD give a precise description and the authors plea for an exchange between disciplines and a sex positive treatment approach.

Authors: Peer Latif Ahmad , Dar Zahoor A. , Lone Aijaz A. , Bhat Mohd. Yaqub 
Published: July 2022

Background: Drought is the critical abiotic stress constraining the productivity of maize and lack of germplasm possessing drought tolerance results in low maize productivity in Kashmir. Because only 15% of the land in Kashmir Valley is irrigated and 85% of the land is rainfed, maize landrace evaluation for drought desirable traits becomes important. Methods: To identify elite genotypes for drought tolerance, seventy maize landraces designated as K-L 1 to K-L 70 from Kashmir were evaluated for morpho-physiological traits: shoot height, shoot biomass, root depth, root biomass allocation, shoot to total biomass, root to total biomass, relative water content, canopy temperature, cell membrane stability and chlorophyll content. Result: A significant decrease in root and shoot traits, relative water content, cell membrane stability, chlorophyll content and a significant increase in canopy temperature was recorded under drought conditions. The evaluation led to identifying landraces exhibiting desirable traits for drought tolerance that would prove useful for further crop improvement.

Published: July 2022

Background: India is experiencing a severe scarcity of edible oil, owing to high demand caused by population growth, rising living standards and increased demand from oil-consuming sectors. Sesame crop cultivation is gaining traction as a way to overcome the oilseed gap. The main aim of this study is to identify the suitable high yielding cultivar of sesame and to standardize the sulphur levels to obtain higher yield and quality. Methods: The present investigation was carried out at S.V. Agricultural College Farm, Tirupati campus of Acharya N.G. Ranga Agricultural University during summer, 2019 in factorial randomized block design (RBD) with four varieties (YLM-66, YLM-17, YLM-11 and Madhavi) and four levels of sulphur (0, 20, 40 and 60 kg S ha-1). Result: The variety madhavi (V4) took fewer days to attain 50 % flowering and maturity and the variety YLM 66 (V1) recorded higher number of capsules plant-1, seed yield, protein content, gross returns, net returns and benefit: Cost. Application of 60 kg S ha-1 recorded higher yield and yield attributes, oil content, gross returns and net returns of sesame which was however found on par with 40 kg S ha-1. The interaction between sesame varieties and sulphur levels in influencing all the above parameters were found to be non-significant. In conclusion, the present study revealed that the variety YLM 66 (V1) with application of 60 kg S ha-1 gave higher yield and quality of sesame.

Published: July 2022

The researcher aims to examine student attitudes, interests and learning outcomes considering that students’ attitudes and interests are in line with and affect student learning outcomes, especially in science lessons. The research method was in the form of mixed methods with explanatory design. The results of the t-test are of students’ interest in learning, student attitudes and student learning outcomes in the science subjects of classes VII A and VII B. Subsequently, there are differences in students’ interest in learning in both classes; there are differences in students’ attitudes in both classes; and student learning outcomes indicate that there are differences in learning outcomes in both classes. The results of the regression test of students’ interest in learning, students’ attitudes and student learning outcomes in the science subjects of classes VII A and VII B conclude that there is an influence between students’ interest in learning, students’ attitudes and student learning outcomes in science subjects. The novelty of this research lies in the variables used in this study, namely three variables that were studied directly consisting of students’ interests, attitudes and science learning outcomes. The implications of this research function as a reference for teachers and students in improving students’ science learning outcomes.

Published: July 2022

Transformational leadership is a leadership style that prioritizes commitment values, patterns, and performance to achieve organizational goals needed in the 21st century. This leadership style is widely applied in developing countries and has the best educational status in the world, such as in Finland and the United States. Researchers have recommended that transformational leadership is an important aspect of teacher performance; however, whether the effect varies across related studies and the robustness of the overall effect size remains unclear. A meta-analysis technique was used to synthesize the results from 65 independent studies and investigate the overall relationship between transformational school leadership and the three measures of teacher performance. This study found that, in terms of the average influence measure, transformational school leadership positively influenced teacher job satisfaction, commitment, and self-efficacy

Impact of regulatory features on waste management in Northern Europe
Authors: Ivanova L 
Published: July 2022

The article discusses the problem of waste management relevant for the Russian Federation and its Arctic regions on the example of a number of Arctic states – the countries of Northern Europe. The existing waste management system, features of the relevant regulatory framework and competition development in this area are considered. The legislative framework of waste management in the northern countries is heavily influenced by the European Union directives and international law. The northern countries have much in common, including cultural and legislative traditions, however there are significant differences between them.
In most northern countries, existing laws and other regulations to some extent limit competition in waste management. It imposes obligations, but at the same time provides broad waste management rights. Within the current legislative framework, there are opportunities to increase competition in the field of waste management. However, the existing regulatory framework may not be sufficient to improve the market structure or create new waste markets.
Protecting Indigenous Collective Land Property in Indonesia under International Human Rights Norms
Authors: Fahmi Chairul , Siddiq Armia Muhammad 
Published: July 2022

This essay examines the applicability of international human rights instruments as the legal basis to protect indigenous rights to land, territories, and natural resources to non-ratification countries of the Convention on indigenous peoples’ rights, especially to the Indonesian context. In the last few decades, the United Nations has developed and recognized the rights of indigenous peoples, including rights to their ancestral lands, territories, and resources. These rights have been stipulated in several instruments, such as the ILO Conventions No.169 and UNDRIP. Nevertheless, most Asian and African countries have not ratified the Treaty, including Indonesia. Consequently, the rights failed to be adopted into national policies, which the ratification is a pre-condition before came into force through the national regulations. Indonesia also doubted the exclusive rights of land, territories, and resources traditionally owned by indigenous peoples. Legally, lands, territories, and resources are controlled by the States, as mentioned in Article 33 of the 1945 Constitutional law. Economically, Indonesia relies on land, territories, and natural resources to boost its national revenues. To achieve this aim, the expropriation of indigenous land and territories often occurs through land concession policy for private or state-owned companies. As a result, land tenure and social conflict were common phenomena from the New Order Regime until the current day. This conflict spreads across the country from the west part (Sumatra) to the east of Indonesia (Papua). Therefore, author argues that applying general international human rights instruments will be an alternative approach in protecting the fundamental rights related to their traditional land rights in the Indonesian context.
