Published: October 2022

Background Undernutrition among adolescent girls is a major public health problem. Despite the adolescence period being a unique opportunity to break the intergenerational cycle of malnutrition, in Ethiopia, particularly in the study area information regarding the nutritional status of adolescent girls is lacking. Therefore, this study aimed to fill this identified gap. Objective To assess the prevalence of undernutrition and associated factors among rural adolescent girls in Daramalo district, Southern Ethiopia. Methods: A community-based cross-sectional study was conducted among 672 adolescent girls from March 11 to April 11, 2021, using a systematic random sampling technique. Anthropometric measurements were analyzed by WHO Anthro plus software for Z-score. The data were entered into Epi data version 3.1 and analyzed with SPSS window version 25.0. Binary logistic regression analysis was used to identify factors associated with undernutrition. Adjusted odds ratio (AOR) and 95% confidence intervals (CI) were used to measure the strength of association and a p-value less than 0.05 was used to declare the level of statistical significance. Results The prevalence of thinness and stunting was 12.6% (95%CI: 10.3%, 15.2%) and 21.1% (95%CI: 18.3%, 24.3%), respectively. Large family size (AOR = 3.23; 95%CI: 1.87, 5.58), ≤ 2 meal frequency (AOR = 3.21; 95%CI: 1.59, 6.45), being non-menstruating (AOR = 4.24; 95%CI: 2.36, 7.61), poor and medium wealth index (AOR = 2.34; 95%CI: 1.15, 4.72) and (AOR = 3.16; 95%CI: 1.61, 6.21), and inadequate dietary diversity (AOR = 2.23; 95%CI: 1.34, 3.68) were factors significantly associated with an increased odds of thinness. Whereas, early adolescence (AOR = 1.54; 95%CI: 1.04, 2.28), large family (AOR = 1.85; 95%CI: 1.24, 2.77), separate decision making on nutrition service by father or mother, (AOR = 3.21; 95%: 1.68, 6.14) and (AOR = 3.01; 95%CI: 1.76, 5.15), inadequate dietary diversity (AOR = 2.12; 95%CI: 1.41, 3.19), and household food insecurity (AOR = 2.24; 95%CI: 1.48, 3.41) were factors significantly associated with an increased odds of stunting. Conclusions Stunting and thinness were found to be high in the study area. Future interventions and programs may consider strategies to improve dietary diversity, food security, wealth status, household decision-making power, meal frequency, and family size through increasing the awareness of the community on the intergenerational effect of adolescent undernutrition and by strengthening community-based adolescent nutrition programs.
Genetic Dysregulation of Immunologic and Oncogenic Signaling Pathways Associated with Tumor-intrinsic Immune Resistance: A Molecular Basis for Combination Targeted Therapy-Immunotherapy for Cancer
Authors: Hargadon Kristian Michael
Published: October 2022

Since the turn of the century, advances in targeted therapy and immunotherapy have revolutionized the treatment of cancer. Although these approaches have far outperformed traditional therapies in various clinical settings, both remain plagued by mechanisms of innate and acquired resistance that limit therapeutic efficacy in many patients. With a focus on tumor-intrinsic resistance to immunotherapy, this review highlights our current understanding of the immunologic and oncogenic pathways whose genetic dysregulation in cancer cells enables immune escape. Emphasis is placed on genomic, epigenomic, transcriptomic, and proteomic aberrations that influence the activity of these pathways in the context of immune resistance. Specifically, the role of pathways that govern interferon signaling, antigen processing and presentation, and immunologic cell death as determinants of tumor immune susceptibility are discussed. Likewise, mechanisms of tumor immune resistance mediated by dysregulated RAS-MAPK, WNT, PI3K-AKT-mTOR, and cell cycle pathways are described. Finally, this review brings attention to the ways in which genetic dysregulation of these immunologic and oncogenic signaling pathways are informing the design of targeted interventions to restore immune susceptibility of cancer cells and enhance immunotherapeutic efficacy through combination targeted therapy-immunotherapy regimens that overcome the resistance mechanisms known to limit the success of monotherapies.
WITHDRAWN: Microplastic accumulation in aquatic insects of different feeding guilds collected from wastewater in Sohag Governorate, Egypt
Authors: ali
Published: October 2022

Microplastics (MPs) have been detected in many freshwater organisms because of increasing plastic contamination within the freshwater environment. However, the correlation between MPs in organisms and their surrounding environment still needs studies. This study investigates MP contamination in one of the wastewater ponds east of Sohag Governorate, Egypt. Four common freshwater insect families representing different feeding guilds were employed to detect MPs contamination.
Revisit the performance of Doppler positioning with LEO satellites
Authors: Shi Chuang , Zhang Yulu , Li Zhen
Published: October 2022

Recently, the Doppler shifts from Low Earth Orbit (LEO) satellites have been used to augment GNSS and provide standalone positioning, navigation and timing services in opportunistic navigation frameworks or GNSS-like navigation systems. In this paper, we proposed a Doppler-only point-solution algorithm for GNSS-like navigation systems operated in LEO. In these systems, LEO satellites are assumed to be modified to support navigation capabilities. Their positions, velocities and clock drifts could be obtained from ephemeris. The proposed point-solution algorithm can estimate the receiver clock drift, position and velocity simultaneously. Then, the main error sources in Doppler positioning are analyzed. As one of the main error sources, satellites’ position error of several meters and velocity error of several centimeters per second would reduce the positioning performance significantly. The LEO doppler positioning accuracy will deteriorate if there are no error corrections for the ionospheric and tropospheric delay rates. Subsequently, the performance of Doppler positioning algorithms is analyzed. The Zero-Difference Doppler positioning accuracy is in meter-level, which is comparable with pseudorange-based positioning in GNSS. By doing difference between satellites, the receiver clock drift is eliminated and the Between-Satellite-Difference Doppler positioning accuracy is improved by about 10% as Doppler Dilution of Precision is reduced by 12.3%. Moreover, we analyzed the sensitivity of initial position error in the LEO-based Doppler positioning and found that the initial position error should be less than 300 km to ensure convergence.

Published: October 2022

The blending of π-conjugated molecules with polymeric semiconductors is an effective strategy to promote the charge carrier mobility because of the transmission path by the conductive polymers through electrical bridge connection of the small organic molecule crystalline domain. In this work, pentacene single crystal was prepared to induce the molecular orientation of polymeric semiconductor PDPP2T-TT-OD, which led to an enhanced field-effect mobility of the organic thin-film transistor (OTFTs) by improving the crystallinity due to nucleation and growth phase separation. Besides, with the addition of anti-solvents, the crystallization of the blend film was further improved, 27 times higher than that of a pure polymer semiconductor-based OTFTs. That was because the pentacene nuclei induced polymer crystallization through π-π interactions and the addition of antisolvent promoted the aggregation of polymer chains in solution, enabling the molecular chains packed more closely in solid films. Therefore, the chain arrangement of polymers induced via small molecular single crystals provides a new idea to improve mobility in composite semiconductor thin films for the construction of novel organic optoelectronic devices.

Published: October 2022

The wide application of polysaccharide-based aerogel is limited by its hydrophilicity. To solve this problem, sodium alginate/ sodium carboxymethyl cellulose (SA/CMC) with silica nanoparticles and methyl trimethoxysilane as hydrophobic modifiers was prepared in this study. The sodium alginate (SA) and sodium carboxymethyl cellulose (CMC) were selected because of their low cost and easy of combination with the other two materials. After the silane reagent modification, Ca2+ crosslinking, surface plasma treatment, thermochemical vapor deposition and freeze-drying methods, the aerogel get density of 0.080 g/cm3, high porosity of 94%, three-dimensional porous structure with great adsorbed ability. This superhydrophobic SA/CMC aerogel exhibits excellent water stability, appropriate compressive strength and good adsorption capacity of cationic dye methylene blue (MB). And the adsorption process is analyzed by adsorption kinetics. Meanwhile, this aerogel gets great absorbency and efficiency towards varieties of organic solvents, which gives it great potential of being used in the field of oil-water separation, textile dye wastewater treatment, etc. Moreover, this aerogel is expected to be recycled after washing.

Published: October 2022

Due to its wide distribution, the long-distance oil and gas pipeline will inevitably pass through the landslide risk area. And pipeline landslide disaster has become one of the biggest threats to pipeline safety because of its multiple. The field monitoring method is time-consuming and expensive, and the probability of monitoring the whole process of landslide pipeline disaster is extremely low, and these problems can be effectively solved by physical models. A large physical simulation platform of oil and gas pipelines influenced by landslide geological disasters was designed and established. Under different dip angles of landslides was conducted, and the changes of stress and strain pipeline, and soil displacement during the test process were monitored and analysed. The experimental results show: (1) the bending process of the pipeline can be divided into slow-bending stage, constant-speed bending stage, and accelerated-bending stage. (2) The tensile strain is produced back to the impact direction of landslide; the compressive strain is produced facing the direction of landslide. (3) When the pipeline is in the accelerated-bending stage, the pipeline stress presents a linear and rapid increasing state, and rebounds occurs after reaching the maximum. (4) At the centre of the pipeline, the strain difference between back and facing the direction of landslide increases continuously. These experimental results have obtained the pipeline deformation law in the whole process of pipeline landslide disaster, which can provide great help for the monitoring and early warning of pipeline landslide disasters on site.
Precise measurement for 3D laser scanner with large range
Authors: Sheng Wei-wei
Published: October 2022

High precision and large measurement range are the target of any one three-dimensional scanner. For a laser scanner, measurement precision depends on its calibration results, i.e. determining mathematical expression of the light plane in camera coordinate system. However, as calibration results are locally optimal solutions, high precise measurement in a large range is difficult. In this paper, we give a precise measurement method and the corresponding calibration procedure for a laser scanner with a large measurement range. With the help of a linear translation stage and a planar target, functions which gives the relationship between center point of the laser stripe and the perpendicular/ horizontal distance are obtained. Once image of light stripe is captured, we can get a precise measurement result from the normalized feature points. Compared with a traditional measurement method, distortion compensation is not necessary and precision of measurement is improved significantly. Experiments show that root mean square error of measurement results according to our proposed method is reduced by 64.67% related to the traditional method.

Published: October 2022

Bulk solids stacking in terminals, ships, trains and other bulk solids storage yards is always challenging considering the requirements of the optimal utilization of the storage area. In this study, the stacking shapes of a variety of bulk solids with different particle sizes were tested, and the curved shapes of the stockpiles were extracted to establish the actual three-dimensional models of the bulk solids accordingly. The three-dimensional curved stockpiles were used to design the bulk solids stacking strategy where the bulk stacking locations, the stacking volume and the flatness of stacking were optimized. A modified golden section method with a self-influenced factor was developed to improve the calculation efficiency of the stacking algorithm for bulk solids stacking flatness. Furthermore, the bulk solids stacking strategy and algorithm were verified by experiments. The results showed that the curved three-dimensional models were very close to the actual shapes of the bulk solids stockpiles while the improved golden section method was more accurate and efficient than the traditional golden section method in finding the optimal values of the stacking volumes for flatness. For different bulk solids tested, the experiment results showed that good flat stacking can be achieved by the developed stacking strategy.

Purpose
The safety of an MRI simulation-guided boost after short-course preoperative radiotherapy (SCPRT) for unresectable rectal cancer is assessed with a planned interim analysis.
Methods and materials
Patients diagnosed with clinical stage T3-4 or regional lymph node-positive disease with positive mesorectal fascia (MRF) or T4b disease evaluated by pelvic MRI were randomly assigned to the SCPRT-boost group (25 Gy over 5 fractions plus 4 Gy delivered to the gross tumor volume, followed by four cycles of chemotherapy) or preoperative chemoradiotherapy group (50 Gy over 25 fractions with concurrent chemotherapy). Then, patients received total mesorectal excision surgery after preoperative treatment. The primary endpoint was the R0 resection rate. The interim analysis was performed when 42 patients completed their assigned treatments.
Results
From October 2018 to November 2019, a total of 43 patients were enrolled, and 42 patients were included in the interim analysis. During preoperative therapy, grade 3 or above toxicities were observed in 10/21 (47.6%) patients in the experimental group, and 4/21 (19.0%) patients in the control group. A total of 17 (81.0%) and 13 (61.9%) patients in the experimental group and control group underwent surgery, respectively. Overall, 69.7% of the patients achieved R0 resection or clinical complete response (cCR) in the intention-to-treat analysis. Surgery-related adverse complications were observed in 2 patients (11.8%) in the experimental group and 1 patient (7.7%) in the control group.
Conclusion
Our results show that the toxicity of an MRI simulation-guided boost dose after short-course preoperative radiotherapy (SCPRT) for unresectable rectal cancer is acceptable. Thus, this clinical trial will be continued as planned.
A variational derivation of Stoney-like formulas for self-stressed bilayered plates
Authors: DiCarlo Antonio , Rizzoni Raffaella , Paroni Roberto
Published: October 2022

Since the beginning of the 20th century, it is known that the spontaneous bending of heterogeneous bilayered plates correlates with the self-stress due to the contrast in the material properties of the two layers, and that this correlation can be exploited to gauge the internal stress state. Over the last decades, ever-growing device miniaturization has made stress assessment and even stress engineering an area of major technological interest. In this paper, we obtain two effective 2D models accounting for the spontaneous bending of devices comprised of a thin substrate and a much thinner coating by applying a Gamma-convergence technique to the standard 3D linear hyperelastic model of a bilayered plate. Our procedure is characterized by the introduction of two distinct smallness parameters plus three independent energy scaling parameters.

Marine macroalgae are nutraceuticals rich in nutritional profile and secondary bioactive metabolites. However, they have varied nutritional and biochemical qualities due to a variety of reasons. This study aimed to determine the phytochemical profile and biological activities of Caulerpa racemosa, edible green algae also known as Sea grapes. The study successfully identified secondary metabolites through metabolomic profiling untargeted by LC-HRMS as well as a bioactive peptide. In addition, antioxidant activity and cytotoxicity of extracts and compounds were determined. A total of 103 metabolites were identified in C. racemosa extract obtained by the maceration, while 48 were detected in the soxhlet extract. A peptide with the sequence ELWKTF (Glu-Leu-Trp-Lys-Thr-Phe; C41H58N8O) and its abundance was identified in the α-chymotrypsin hydrolysate of C. racemosa. In the antioxidant activity test, Soxhletated-extract (ES) and purified fraction 1 (PF1) had half-maximal effective concentration (EC50) < EC50 of control/GSH (DPPH inhibition) and PF1 had EC50 < EC50 of control/Trolox (ABTS inhibition). The cytotoxicity results showed that macerated-extract (EM), ES, and PF1 as antioxidant agents in the observed EC50 were safe. In general, C. racemosa contains antioxidant nutrients, metabolites, and bioactive peptides, a factor that makes it a promising functional food and pharmaceutical.

Published: October 2022

Background
Self-evaluation, as an expression of self-concept, becomes increasingly complex in adolescence. Parental bonding, personality traits, and psychological status were the three main determining factors of adolescents’ self-evaluation. We aimed to tested associations through a systematic approach.
Methods
Data were from the 2014 Chinese Family Panel Studies (CFPS). The association of parental bonding (measured by the Parental Bonding Instrument), personality traits (the Responsibility Scale), and psychological status (the Kessler Psychological Distress Scale) with self-evaluation measured in three domains (the Rosenberg Self-Esteem Scale, the Nowicki- Strickland Locus of Control Scale for children and the Self-Discipline Scale) were tested by the structural equation modeling (SEM) analysis.
Results
A total of 892 Chinese adolescents were included. Significant positive correlations were found among self-evaluation, parental bonding, personality traits, and psychological status. The overall (direct and indirect) effect of parental bonding on adolescents’ self-evaluation was 0.49. Personality traits and psychological status were directly associated with adolescents’ self-evaluation.
Conclusion
The use of SEM offered a detailed analysis of the correlations between parental bonding, personality traits, and psychological status and a systematic approach to investigate their direct and indirect effects on adolescents’ self-evaluation. The three factors directly associated with adolescents’ self-evaluation and parental bonding indirectly affected adolescents’ self-evaluation that was mediated by both personality traits and psychological status.

Die Zusammenarbeit von Schulen, Schulträgern und weiteren Akteuren in Netzwerken kann dazu beitragen, Schulentwicklungs-, Innovations- und Transformationsprozesse zu initiieren und zu unterstützen (Endberg et al. 2020). Der vorliegende Beitrag geht der Frage nach, inwiefern solche Netzwerkkooperationen die digitale Transformation an Schulen unterstützen können. Im Mittelpunkt des Beitrags stehen Schulnetzwerke, die in unterschiedlichen Kontexten gegründet und deren Konzepte sukzessive weiterentwickelt und ausgebaut wurden. Die betrachteten Schulnetzwerke wurden in Regionen oder Kommunen gebildet, in denen sich Schulen und andere Akteure zum Thema «Bildung im digitalen Wandel» zusammengefunden haben, um gemeinsam Schritte der Integration digitaler Medien in den Schulalltag zu entwickeln und zu erproben. Der Beitrag analysiert, was die Netzwerkarbeit zur (kooperativen) Schulentwicklung im Kontext von Digitalisierung beitragen kann und wie sie zu organisieren ist, damit Zusammenarbeit – auch über die eigene Schule hinaus – gelingen kann. Der Beitrag erläutert dazu die Anlage von Netzwerken sowie die Arbeit in den Netzwerken aus Sicht der Moderation. Es wird speziell darauf eingegangen, welches Potenzial die Netzwerkarbeit hat, um kooperative Arbeitsformen im Sinne einer Ko-Konstruktion (Gräsel et al. 2006) zu fördern, welche über den reinen Austausch von Information oder Material hinausgehen und welche Inhalte, angelegt an die Schulentwicklungsdimensionen (Rolff 2016; Schulz-Zander 2001; Eickelmann und Gerick 2017) sich für die Zusammenarbeit anbieten.

Published: October 2022

Im Mittelpunkt des Beitrags steht die Bedeutung von Kooperation und Unterstützung im Schulkollegium für die erfolgreiche und nachhaltige Implementation von digitalen Medien und Medienbildung in der Schule. Ergänzend zu der bisher in der Forschung dominierenden Perspektive auf Lehrpersonen wird auf der Basis einer rekonstruktiven Analyse von 21 Interviews mit verschiedenen schulischen Akteur:innen herausgearbeitet, dass und in welchen Formen die Lehrpersonenkooperation darüber hinaus eine wichtige Rolle spielt. In der Analyse wird deutlich, dass den Medienbeauftragten und Schulleitungen bei der Unterstützung der digitalisierungsbezogenen Lehrpersonenkooperation eine besondere Bedeutung zukommt. Medienbeauftragte sind demnach nicht nur häufig Teil der digitalisierungsbezogenen Lehrpersonenkooperation, sondern initiieren die Kooperation mit und prägen diese massgeblich. Zudem kann die Rolle der Schulleitung bei der Unterstützung schulischer Kooperationsformen sowohl bekräftigt als auch genauer beleuchtet werden. Der Beitrag liefert damit insgesamt ergänzende und aufschlussreiche Perspektiven auf das komplexe Zusammenspiel schulischer Akteur:innen bei der digitalisierungsbezogenen Lehrpersonenkooperation.

A multi-methodological study of the bastnäsite-synchysite polysomatic series: Tips and tricks of polysome identification and the origin of syntactic intergrowths
Authors: Conconi Roberto , Fumagalli Patrizia , Capitani Giancarlo
Published: October 2022

In this paper, we evaluated the potentialities of Raman spectroscopy and electron backscattered diffraction (EBSD) in the microscopic characterization of Ca-REE fluorcarbonates (CRFC) belonging to the bastnäsite-synchysite series to provide a “road map” for further investigations with transmission electron microscopy (TEM). EBSD was effective in establishing the sample orientation, setting up the oriented cuts, and ascertaining the effective syntactic relationship among all the detected CRFC phases; however, it failed to distinguish between different polysomes. On samples with different orientations that were preventively ascertained by EBSD and characterized by scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS), micro-Raman spectroscopy allows for distinguishing between polysomes based on the differences in intensity and position of the symmetric stretching vibration (ν1) of the carbonate group (CO32–) in the region around 1080–1099 cm–1. However, as evidenced by TEM-EDS, what appears as a homogeneous polysome in backscattered electrons (BSE) images may be a disordered intergrowth of compositional faults with a bulk composition being matched with that of a real polysome only by accident. Therefore, we conclude that the Raman signal is sensitive to different Ca/(Ca+REE) ratios but not to any ordered distribution of Ca-poor and Ca-rich lamellae within the analyzed volume, making the unambiguous identification of a polysome tricky. Finally, several ordered polysomes were detected at the TEM scale, including a B2S and a long-range polytype with a 32 nm repeat distance along c. The possible implications of the detected microstructure for ore mineral formation are discussed.
The equilibrium boundary of the reaction Mg3Al2Si3O12 + 3CO2 = Al2SiO5 + 2SiO2 + 3MgCO3 at 3–6 GPa

Published: October 2022

The stability of CO2 fluid in the Earth’s mantle is restricted by the carbonation of rock-forming minerals. Among those, the reaction with garnet is of particular interest because it constrains the stability of CO2 fluid in eclogites, whose minerals have been found in the CO2-bearing diamonds. In this work, we determined the equilibrium boundary for the reaction Mg3Al2Si3O12 (Prp) + 3CO2 (fluid) = Al2SiO5 (Ky) + 2SiO2 (Coe/Qz) + 3MgCO3 (Mgs) over the pressure interval 3–6 GPa using a multi-anvil press. Owing to the slow kinetics, the reaction was studied in both forward (left to right) and reverse (right to left) directions in experiments with durations extending up to 260 h. Our newly determined boundary is situated 3 GPa/950 ± 50 °C, 4.5 GPa/1150 °C, and 6 GPa/1350 ± 50 °C and has the equation P(GPa) = 0.0075 × T (°C) – 4.125. The boundary crosses the graphite-to-diamond transition curve near 4.7 GPa and 1180 °C. Thus, the assemblage garnet + CO2 fluid is stable in the diamond (Dia) stability field under P-T conditions of the continental geotherm with a heat flow of 41 mW/m2.
Ethics in Small Island Research: Reflexively navigating multiple relations
Authors: Hayfield Erika Anne
Published: October 2022

This article concerns research ethics in small, insular communities such as islands and other locales islanded by topography and/or isolation. Using the Faroe Islands as case, the point of departure is a discussion of how islanders navigate multiple relations and how this might impact research ethics. Because relations in such island/islanded communities can be highly interwoven and complex, this article argues for a situated research ethics that is grounded in multiple relations. Most research ethics codes are grounded in Western individualist thought, conceived outside the social sciences and in non-island settings. Furthermore, they may fail to take adequate account of the social interconnectedness, interdependency, and intimacy, which can prevail in small island/islanded communities. Using the concept of reflexive navigation, the article presents a research ethics that encompasses a relational ethics. In doing to, a framework of ethical reflexive navigation is proposed which can support researchers and island research institutions. Within the relational ethics framework, the ethical qualities of attentiveness, responsibility, competence, and responsiveness are applied to research in island/islanded communities.
Neural network approach to reconstructing spectral functions and complex poles of confined particles
Authors: Lechien Thibault , Dudal David
Published: October 2022

Reconstructing spectral functions from propagator data is difficult as solving the analytic continuation problem or applying an inverse integral transformation are ill-conditioned problems. Recent work has proposed using neural networks to solve this problem and has shown promising results, either matching or improving upon the performance of other methods. We generalize this approach by not only reconstructing spectral functions, but also (possible) pairs of complex poles or an infrared (IR) cutoff. We train our network on physically motivated toy functions, examine the reconstruction accuracy and check its robustness to noise. Encouraging results are found on both toy functions and genuine lattice QCD data for the gluon propagator, suggesting that this approach may lead to significant improvements over current state-of-the-art methods.

After swallowing a foreign body, it passes easily into the digestive tract away from the airways tract. This situation especially in adults can lead to serious consequences.We report the case of a patient who underwent an urgent laparoscopy for suspicion of appendicular peritonitis, leading rather to the discovery of a perforation of the sigmoid colon by a small chicken bone, ingested three days prior by the patient. The surgical procedure consisted in closing the colonic breach after the removal of the foreign object. The postoperative follow-up was uneventful.The diagnosis of this peritonitis of colonic sigmoidal origin was difficult, confusing, and unknown because of the rarity of this incidence.The early consultation of our patient once the ossicle had been swallowed, could have avoided the emergency surgery, by performing its extraction endoscopically or to follow its migration in the digestive tract viaintermittent X-rays or abdominal scans.
Towards Liveable Urban Densities Using a GIS-Based Assessment Methodology
Authors: Kovács-Györi Anna , Gruber Günter , Mehaffy Michael , Ma Lei
Published: October 2022

Urban density and densi fication are hotly debated topics of sustainable urban development. On the one hand, international landmark agreements such as the Sustainable Development Goals and the New Urban Agenda highlight the importance of good quality urban environments with low pollution,
easy access to green spaces, walkability, and active mobility. On the other hand, densi fication can increase pollution, decrease available green spaces, and degrade walkability by concentrating vehicles and their operations. The result can be a degradation of urban liveability, de fined as
a city's capacity to promote the wellbeing of residents. Yet higher urban density can also result in more effi cient urban infrastructures and networks and provide more housing (including more aff ordable housing) in more appropriate mixed-use locations. The challenge, then, is to maintain
the liveable quality of this denser urban fabric. The GIS-based approach presented in this paper uses a basic liveability assessment by calculating connectivity, greenery, and urban form complexity metrics to be employed in the context of densi fication, aiming to optimize sustainability and
liveability aspects. Using our study area in Salzburg, Austria, we demonstrate how such a GIS-based liveability assessment, relying on spatial data, can aid urban planners in quantifying and achieving both urban density and liveability.

All dimensions of liveability, from economic to social, are directly related to urban space and its production process. However, the production of urban space, with its forms and functions, is always situated in the con flicting domain of (spatial) political economy. Conventional space
production processes that favour dominant classes and produce space regarding exchange value are frequently contested with the social reaction of dominated classes defending use values and liveability. In this vein, Urban Social Movements (USMs) seem one of the key instruments for the social
production of urban space with be er liveability conditions. From this perspective, the study aims to investigate USMs' space transforming capacity by focusing on the case of Istanbul. A five-step spatial analysis is conducted, assuming that USMs are closely related to the characteristics
of urban development projects. In these steps (i) the location of the urban development projects and USMs; (ii) existing land use in the project areas; (iii) scale of the projects, (iv) organization level of USMs; and (v) relationships of four USM-related projects within the urban fabric are
analysed. Findings of the study reveal that centrality plays a vital role in both development projects and related USMs and aff ects the programme, scale, and organization level. Considering liveability conditions, faced with aggressive capitalist behaviour supported by local and central state
apparatus, USMs can realize their space transforming potential only by protecting existing programmes and urban fabric.
Potential of CCS at SC Achema
Authors: Tunaitis Juozas
Published: October 2022

Achema is a leading producer of nitrogen fertilizers and chemical products in Lithuania and the Baltic states. First construction works of the factory date back to 1962, however officially the company was founded on February 9, 1965 after the first tons of synthetic ammonia were produced in a newly launched ammonia unit.

Carbon capture and sequestration has been considered as suitable measure of decarbonization during middle term – till year 2030. There is developed technology and logistic chains for on shore and offshore projects. The geographical location of companies plays crucial role because of logistics. SC “Achema” yearly emits more than 2 million tons of CO2. Our advantage is in having 200-300 kilo T of pure CO2 suitable to liquify and transport. Disadvantage of this topic in Lithuania is political attitude and big distances till real wells at North Sea. The deep check of all aspects necessary to estimate real potential of CCS in Lithuania.

The company aspires for significant reduction in greenhouse gas emissions and is the winner of ‘Most Environment Friendly Process' nomination for greenhouse gas emission (NO) mitigation in the nitric acid manufacturing process. Company aspires for sustainable and safe production of fertilizers and has also has also developed capabilities to liquify and transport CO2 over long distances.

In this conference Achema’s capabilities to liquify 200-300 kilo T of pure CO2 will be highlighted. Potential challenges related to long distance transfer and political challenges will be also be highlighted.
Greensand project – transport and offshore storage of CO2 in Denmark – status, outlook and challenges
Authors: Poulsen Søren Reinhold
Published: October 2022

The Greensand project includes, beside from safe and efficient geological offshore CO2 storage, offshore transport by ship and/or pipeline of CO2 from key side onshore facilities established to capture, liquefy, onshore transport and temporarily store the CO2 before offloading to storage site. The Greensand project builds on the usage of the offshore Siri complex sandstone reservoirs no longer in use for oil and gas production. The storage sites, offloading and injection systems and transportation means are currently being technically matured. The target is to be able to offer customers safe and reliable transport and storage services from the start of 2026. Currently meanwhile maturing a technical concept, commercial and regulatory activities are ongoing in parallel. The Greensand partners INEOS Energy and Wintershall Dea have also decided to perform an offshore pilot test of injecting liquified CO2 into a particular reservoir serving as candidate for future long terms storage of CO2. Along the pilot testing offshore project, material testing and deployment of monitoring techniques are being matured. The Pilot testing offshore planned to take place late 2022 with a 3-months duration.
Screening of future carbon storage sites – selecting the best spots
Authors: Neumaier Martin
Published: October 2022

Subsurface carbon storage can occur in depleted oil and gas fields, in water-wet structures, or in open aquifers. All three types of storage sites present advantages and inconveniences, which will be reviewed in this talk. The selection of future sites for carbon storage balances storage capacity (how much CO2 can be stored), injectivity (how efficiently or fast CO2 can be stored), and containment risk (how safely CO2 can be stored). We present a rigorous uncertainty-based approach involving estimates of pore volume, pressure and temperature conditions and resulting fluid properties, and sealing and containment behaviour, to highlight areas with best potential for safe and effective carbon storage.
Public acceptance of CCS/CCUS technology in onshore areas in NW Poland

Published: October 2022

The research is a part of the AGaStor project realized in AGH-UST and University of Stavanger. The aim of the paper is to present social aspects of the developing the CCS/US technology in Poland described as social awareness (SA) and public acceptance (PA). The main research questions of the CCS/US PA concentrates on knowledge, acceptance of the technology, risks and benefits, the existence of NIMBY movements [1].

The quantitative method of analysis of CCS PA is a survey method. The most of the former research was realized only in small communities [2, 3]. The AGaStor research describes the mezzo-social level of the CCS/US PA. The randomized sample (N= 695) was made in Zachodniopomorskie region (West-North Poland) in 2021. It allows to recognize differences of the level of CCS/US PA in different in that part of Poland. The main variables which influence CCS/US PA are: place of living, education, economic situations and general worldview of the respondents.

The results show the correlation between place of living and CCS PA (higher PA in big cities); education with CCS SA (higher declarations of knowledge and SA by well educated people); NIMBY potential in villages and small towns, and the pro-technological worldview with the CCS PA. The research points that the main social obstacle is the lack of knowledge about the CCS/US technology. Even respondents who declare the general acceptation of new technologies in energy production are ambivalent towards acceptance of CCS/US.

Published: October 2022

The rapid expansion of slums with increasing population density are the main barriers to scaling-up sustainable Water, Sanitation, and Hygiene (WASH) facilities in the megalopolis of Dhaka, Bangladesh. The improper arrangement of ‘Cheap WASH’ (i.e., water access, sanitation access, and hygiene practices) and unmanaged disposal of non-biodegradable menstrual hygiene wastes, single-use medical, and plastic usage at slums are making the environment of city surroundings unfavourable and vulnerable posing a great threat to public health. Among the slum-dwellers, particularly, females with a disability are mostly the worst affected and vulnerable due to unfavourable conditions and lack of necessary support. Following the backdrops, this study purposively selected two Dhaka slums, with and without disabled-friendly facilities, to investigate female perspectives on different aspects related to WASH and menstrual hygiene management (MHM) for females with a disability. In total, 30 in-depth interviews, 12 focus group discussions, and 22 key informant interviews were conducted at Korail and Kalyanpur slums. Case studies from the megalopolis of Dhaka, Bangladesh, capture the economic burden added to the budgetary deficits of the family with female-disabled. Discrimination in extra care needed for toilet facilities, MHM education, and transport and overlooking the caretaker's requirement or loss in income are found as additional burdens.
Личностное развитие молодых людей в условиях неопределенности внешнего мира
Authors: Горохова Екатерина Г.
Published: October 2022

В данной статье автором исследуются взаимосвязи показателей личностного развития молодых людей и феномена толерантности к неопределенности.  Новизна исследования заключается в предложенном для рассмотрения факторе успешного личностного развития как основе для развития высокого уровня толерантности к неопределенности. Во «Введении» автором обосновывается актуальность рассмотрения феномена толерантности к неопределенности у молодых людей в связи быстро и непредсказуемо меняющимися условиями окружающего мира.

В разделе «Методы» описывается организация исследования, в котором приняли участие 84 респондента – молодые люди в возрасте от 18 до 28 лет. В рамках исследования были использованы следующие методики: опросник диагностики самоактуализации личности А. В. Лазукина в адаптации Н. Ф. Калиной; шкала толерантности к неопределенности Мак­Лейна в адаптации Е. Н. Осина; новый опросник толерантности-интолерантности к неопределенности Т. В. Корниловой.

В разделе «Результаты» представлены основные результаты исследования: была выявлена корреляционная связь средней силы между показателями личностного развития и толерантностью к неопределенности, что позволило сделать вывод о том, что чем выше у молодых людей показатели личностного развития, тем больше они толерантны к неопределенности. Кроме того, была выявлена корреляционная связь средней силы между показателями толерантности к неопределенности и аутосимпатией, а также креативностью. Исходя из этого, позитивная Я-концепция, адекватная самооценка и творческий подход к жизни могут являться основой для развития высокого уровня толерантности к неопределенности у молодежи. В разделе «Обсуждение результатов» представлено сравнение полученных результатов с результатами и концепциями российских и зарубежных исследователей в области личностного развития и неопределенности.

Перспективой дальнейшего исследования является более глубокое и детальное изучение феномена толерантности к неопределенности и его связи с различными показателями личностного развития.
Use of Ground Calcium Carbonate for Self-compacting Concrete Development based on Various Water Content and Binder Compositions

Published: October 2022

Objective:

The development of a Self-Compacting Concrete (SCC) mixture requires a different composition compared to normal vibrated concrete. This experimental study was designed to propose a modification of the concrete mix design formula to produce an SCC mix that meets the specified requirements for both fresh and hardened concrete using Ground Calcium Carbonate (GCC) as local fine powder material.

Methods:

The research was carried out with a targeted compressive strength between 30 and 60 MPa. The materials that were used in this research were fine natural aggregate, crushed stone as a coarse aggregate with a maximum size of 19 mm, Portland pozzolan cement (PPC), GCC, freshwater, and high-range water reducer. The properties of fresh concrete were tested using the slump-flow test method, while the compressive strength test was carried out on 50 standard cylinders after 28 days of curing with water immersion.

Results:

Test results indicated that the compressive strength and fresh properties of SCC significantly depend on the water content, the water/cement ratio, the volume ratio between water to the total binder, and the weight ratio between the GCC and Portland cement.

Conclusion:

Furthermore, using the experimental data based on varied water content and binder compositions produces equations with a good fit for SCC mix design in the compressive strength range between 30 MPa to 60 MPa.
