Published: January 2023

Watersheds have a significant role to play in safeguarding ecosystem services against climate changes and extreme weather events. Thus, these protected areas are widely susceptible to such risks which will significantly affect human communities. This paper is an exploratory study conducted to assess the resilience of CALSANAG Balogo sub-watershed using the estimated Climate Disaster Resilience Index (CliDRI) and capital-based approach. The study used the five resilience-based dimensions; namely: the physical, social, economic, institutional, and natural in the survey conducted in which a total of 35 randomly selected respondents residing in Brgy. Balogo, Calatrava, Romblon were interviewed for the study. The questionnaire covered the five resilience-based dimensions and the 23 indicators selected base don the local context to gain an understanding of the level of resilience of its ecosystem. Results showed that Balogo exhibits above average resilience accumulating a score of 0.58 on a scale of 0-1. The resilience scores varied from 0.43 (average resilience) to 0.80 (high resilience). On the average, resilience levels in the community showed high levels in socila dimension and low levels in the economic dimension. An analysis of the index values were also provided along with the suggested feasible policy recommendations that the community leaders, policymakers, and stakeholders can implement to improve climate and disaster resilience of Balogo.

Authors: Perlas Sherwin
Published: January 2023

This study aimed to develop the Romblon legends in comic book form. Specifically, it aimed to investigate the background of Romblomanon legends in the three languages that could be used for promoting Filipino values of children who are still in the process of assimilating the culture of Romblon, investigate ways to conserve and develop these legends into a comic book form and determine the rating of the comic book as supplementary learning resource materials (SLR) in the elementary level as rated by the Learning Resource Management Development System (LRMDS) Team of DepEd. The Evaluation Rating Sheet for Story Book was used in determining the appropriateness of the SLR material in terms of content, format, and technical aspects; and solicited comments and suggestions from the respondents that served as inputs for the improvement and revision of the legends in Comic book form. It is a descriptive-evaluative investigation. The research area is the whole Romblon Province. The research sample was determined through a dragnet method wherein key informants, casual informants, and general informants were identified in the field. Evidence was gathered from document analysis and field research. Data collection tools were observation, interviews, and focus group discussions. The research was conducted in five stages: planning, development, validation, final output, and dissemination. Of the four legends, 10 Romblomanon values were extracted and incorporated into the stories. It is highly recommended that the streamlined five-stage development process may be used for the comic book development of the rest of the undocumented legends of Romblon.
Effect of Contextual Inquiry Approach on Interest Towards Science and Achievement in Earth Science among Grade 10 Students
Authors: Taratara-Fadero Aizelle
Published: January 2023

This study determined the effect of the contextual inquiry approach (CIA) on interest in science and achievement in Earth Science among grade 10 students at Ferrol National High School. In CIA, students are doing inquiry-based learning using situations and materials that are within their context and locality. The pretest–posttest control group quasi-experimental design was employed in the study, which involved two matched classes of 30 students each, both implementing the 7Es inquiry model: elicit, explore, engage, explain, elaborate, evaluate, and extend. The experimental class used the CIA in conducting the activities and providing examples about the concept while the control group used pictures in delivering 10 learning competencies in Earth Science topics. The instruments used were the 40-item researcher-made achievement test in Earth Science and 12-item Science Inventory Test modified from the Program for International Student Assessment. Results showed that the CIA helped improve students’ achievement in Earth science (ƞp2 = .11). In classes implementing the 7Es inquiry model, CIA is comparable to the conventional teaching approach (CTA) in improving students’ interest in science.  However, interest in science and achievement in Earth Science are not related to each other. This advances the argument that the attitude-achievement paradox is possibly existent among Filipino learners.

Published: January 2023

Science as a subject requires an accurate teaching approach to learn the science content and processes better. This study determined the effect of the carousel strategy approach on the academic achievement in earth and space science of grade six pupils. The pretest-posttest control group quasi-experimental design was employed in this study with two intact classes. One of these groups was the experimental group, wherein carousel strategy (CS) was employed; the other was the control group, wherein the conventional teaching approach (CTA) was used. Pretest and post-test achievement tests and the daily lesson log (DLL) in earth and space science were used as research instruments. The data were analyzed using descriptive and parametric statistics, including the independent samples t-test and paired samples t-test. The results indicated a significant difference between the pretest and post-test of the CS and CTA. The results also showed higher academic achievement of students in the CS group over the CTA group. This study concluded that the carousel strategy is an effective intervention and learning in Earth and Space Science.

Increasing the acceptability of climate neutrality in society
Authors: Laurynaitytė Laura , Pažėraitė Aušra
Published: January 2023

Climate change is seen as a matter of urgently needed decisions and broad public involvement. A climate- neutral society is what the European Union and other developed countries are striving for. At first glance, most members of societies in these countries support or tend to support the idea of climate neutrality. The latter idea can be reached by proper sorting of waste, its further use thus meeting the principles of circular economy, conversion of waste that cannot be re-used into energy, energy saving, responsible and sufficient consumption, and similar actions. However, the trend when members of society are reluctant to engage, proactively and to a large extent, in the pursuit of a climate-neutral idea is common to many countries. Research shows that quite often proactive involvement is hampered by a lack of understanding of this idea and a lack of conscious acceptance. Modern marketing supports storytelling. Therefore, it is a way to educate, provide knowledge, understanding, acceptance, and share the same idea of being climate-neutral with other members of society. This could increase the acceptability of the idea and facilitate its dissemination at a later time. However, there is a lack of scientific evidence to state this as there is not much research in this area, especially in the field of energy. Therefore, the aim of the study is to determine the important issues in increasing the acceptability of a climate-neutral society through storytelling. The approach of qualitative research was chosen to achieve the aim. This was due to the desire to display, in various ways, the phenomenon as such, the potential links between the phenomenon and other variables studied, and to formulate insights and further research directions. An analysis of the results of the study suggests that storytelling could be effective in increasing the acceptability of climate neutrality in society. With the help of storytelling, the acceptance of ideas of climate neutrality can be effectively raised by employing positive emotions, empathy, and certain determined values. Storytelling is a way to establish long-term positive attitudes toward the ideas of a climate-neutral society, as it is much easier to overcome mistrust, provide knowledge and convey a key message. Research has also shown that the use of storytelling can be a more effective tool than conventional informational or action-promoting advertising. This leads to the assumption that it is reasonable to expect that storytelling can both increase the acceptability of a climate-neutral society and ensure that this effect will be long-lasting.
Assessment of the thermal properties for the geothermal use of a permeable pavement structure for pedestrian and cycle paths
Authors: Rey-Mahía Carlos , P. Álvarez-Rabana Felipe , A. Sañudo-Fontaneda Luis
Published: January 2023

Sustainable Drainage Systems (SuDS) have positioned themselves as one of the most widely applied Green Infrastructure (GI) techniques for sustainable stormwater management. In recent decades, new lines of research have emerged leading to the geothermal use of SuDS. The aim is to optimise available space in cities and minimise dependence on non-renewable energy sources. Previous research has focused on determining the feasibility of combining the two technologies, both in laboratory and field studies. Other aspects such as the influence of the surface geothermal system on the quality of the water present in the SuDS were also studied. This previous research has focused mainly on permeable pavements, positioning them as one of the SuDS techniques of reference in this line of research. This article attempts to give continuity to what has been established by other authors. It studies in depth the thermal properties of a complete section of permeable pavement under different hydraulic operating conditions. To this end, a complete section of a permeable pavement has been simulated in the laboratory using Hot-Box tests as set out in different international standards. With these tests, the values of thermal transmittance and equivalent thermal conductivity were determined. The aim of this research is to establish a test procedure for the thermal properties of permeable floorings, based on standardised equipment. The aim is to better understand the heat transfer procedures inside SuDS. In this way, it will be possible to optimise the design of these in combination with surface geothermal elements.

Authors: Harida Issam , Bouras Abdelkarim , Boudiaf Rabah
Published: January 2023

Wind energy is a source of renewable energy derived from the kinetic force of the wind. It has experienced the greatest expansion due, above all, to its low impact on the environment and the gradual reduction of costs, which produce clean, competitive and economically viable energy. In order to ensure the stability of the energy produced, many studies are working to develop a reliable maintenance process based on new online diagnostic techniques, fast and accurate, optimised for wind turbine systems. For this, an experimental study was carried out on a wind system based on electric generators with the aim of contributing to the diagnosis and predictive detection of combined mechanical faults, where the configuration is complex because one fault can hide another. For this, it is imperative to associate each symptom with the appropriate method or methods in order to highlight it unambiguously to detect each defect at the appropriate time. Hence the interest in using more elaborate techniques in order to improve the procedures for detecting and analysing combined faults.

Published: January 2023

NIST Handbook 44 includes specifications, tolerances, and other technical requirements for weighing and measuring devices. These requirements are intended to encourage the design, installation, testing, and use of weighing and measuring devices that provide for accurate, repeatable measurements; facilitate clear and transparent transactions for buyer and seller; and do not facilitate fraud. Handbook 44 is adopted by many state, local, and some federal weights and measures authorities to apply to commercial weighing and measuring equipment and associated equipment and for use in applications for law enforcement and the collection of statistical information by government agencies. NIST has a statutory responsibility for cooperation with the states in securing uniformity of weights and measures laws and methods of inspection and publishes this and other NIST Handbooks in partial fulfillment of this responsibility. NIST Handbook 44 was first published in 1949, having been preceded by similar handbooks of various designations and in several forms, beginning in 1918; the handbook is now typically published on an annual basis. This 2023 edition includes amendments made through the Committee on Specifications and Tolerances of the National Conference on Weights and Measures (NCWM) with technical guidance from the Office of Weights and Measures (OWM) of the National Institute of Standards and Technology (NIST) and input from weights and measures officials and industry representatives. These amendments were adopted by the NCWM at its 107th Annual Meeting in July 2022.
Juliano, hacedor de mártires y arquetipo de maldad
Authors: Sánchez Jaén Jesús
Published: January 2023

Resumen

El ejemplo que podía representar la tolerancia de Juliano resultó tan peligroso que se combatió su imagen de manera expeditiva, llegando al extremo de convertirlo en la personificación del Mal. A tal fin se le atribuyeron crímenes y martirios ficticios, creando un estereotipo que perduró durante varios siglos y que ejemplificaba la aniquilación del enemigo, no solo del pagano, sino también del hereje. Juliano y sus crímenes se convirtieron en algo así como una metáfora de la derrota que Dios infringe a los rivales de la Iglesia oficial.

Authors: Moreva Evgeniya L'vovna , Bekulova Suzanna Robertinovna
Published: January 2023

The Arctic, as an object of modern attention, is a center of attraction not only for Arctic and near-Arctic countries, but also for countries that are located at a fairly remote distance from the Northern Hemisphere. The high interest in the development of the Arctic is caused by geopolitical, economic and other factors. In these conditions, the Arctic becomes a zone of intersection of interests of many countries. The activation and expansion of the economic activity of previously existing and new players in the Arctic can pose both real and potential threats, as well as potential, a new round on the way to improving the level of national security of the Russian Federation in the Arctic region. In this regard, the analysis of foreign Arctic strategies and the study of foreign experience in the development of the Arctic is relevant. The purpose of the work is to analyze the Arctic strategies of the United States, Canada, China, and India for compliance of their national interests with the regional (Arctic) and search for opportunities to use their best practices to ensure sustainable development in Russia. The subject of the study is the mechanisms of management of the development of Arctic and near-Arctic territories. The methodological basis of this study is a systematic, comparative analysis, methods of synthesis, induction and deduction. It is revealed that the models of the policy of supporting the sustainable development of the Arctic of the countries of the North American continent demonstrate ambiguous effectiveness of their implementation. It is shown that the great prospects for supporting the sustainable development of the Arctic contain the emerging and developing models of the state Arctic policy of China and India.

Published: January 2023

In the present work two modifications of the InterCriteria Analysis are proposed in order to extend its theoretical foundation. The results obtained from the application of these methods over real data (from patients with prostate carcinoma) have been analyzed to determine the reliability of the calculated consonance and dissonance.

The similarity scores obtained by the modified versions of the InterCriteria Analysis are close to those given by the classical InterCriteria Analysis, as well as to the values of the correlation coefficients between the considered criteria. This shows the reliability of the proposed modification with respect to determining the consonance and dissonance between criteria in different problems.

Authors: Cebeci Tuğba
Published: January 2023

The aim of the study is to investigate the antimicrobial, biological, and scolicidal activities of Ulva intestinalis (U. intestinalis), which is one of the green algae. U. intestinalis was collected in appropriate amounts and some of the samples were distilled with water vapour to extract their essential oils, and some of them were extracted by Soxhlet extraction with hexane and dichloromethane. The values of lethal concentration doses (LD50 and LD90) were calculated using the probit analysis. Antibacterial and scolicidal effects of the essential oil and solvent extracts of U. intestinalis against gram-positive, gram-negative and yeast microorganisms were studied. It was determined that essential oil and solvent extracts of U. intestinalis may have scolicidal effects. The highest scolicidal activity was observed in 15 000 µg/ml in all organic solvents. Antimicrobial activity was observed for U. intestinalis, with high potency with hexane extract against Enterobacter aerogenes and with dichloromethane extract against Enterococcus faecalis (inhibition zone ≥ 12 mm). It is suggested that controlled in vivo studies should be carried out in order to use this alga as a bactericidal and scolicidal medication.

Authors: Kelek Muhammed , Özer Tolga , Fidan Uğur , Oğuz Yüksel
Published: January 2023

In this study, real-time application and simulation of the load cell-based Segway was carried out by using an STM32F103 microcontroller. The Brushless Direct Current Motor (BLDC) current and speed information was recorded on the SD card simultaneously during the real-time application of the vehicle. The BLDC parameters required for the simulation of the Segway were entered into the block diagram created in Matlab/Simulink interface. Then the load cell-based Segway was simulated. As a result of the simulation, the determined phase currents were compared with the real-time application results. In addition, the repetition test of the load cells was performed, and 99.9% correlation coefficients were obtained from the measurement of each load cell. As a result of this process, the measurement error rate of the load cells was determined as 0.01%. Finally, the currents of the BLDC motors were compared with the simulation study and the real-time application. The similarity of the currents with each other was obtained with an error rate of approximately 1.5–2%.

Characterization of Serpentine Soils from Eastern and Southern Rhodope Mountains (Bulgaria)
Authors: Angelova Violina , Kovacheva Daniela
Published: January 2023

This work aims to characterize serpentine soils in Bulgaria and examine the biogeochemistry of pedogenic Ni and its relation to Ni available forms. Soils were collected from serpentine soils of the Eastern and Southern Rhodopes (Bulgaria). The chemical composition of serpentine soils is similar to serpentine soils from the Balkan Peninsula and is characterized by high contents of Ni (919.9–2397.2 mg.kg–1). The soils had a neutral to slightly alkaline reaction (pH 6.4 to 7.6) and a medium to high organic matter content. Of the primary minerals, those of the serpentine group (antigorite and lizardite), the talc group (willemseite), the amphibole group (riebeckite), the feldspar group (albite) and quartz are mainly present in the soil samples. The secondary minerals present in the samples include calcite and dolomite, and also representatives of the clay minerals, clinochlore and montmorillonite. The contents of free iron oxides (Fed), amorphous iron oxides (Feo), well-crystallized iron oxides (Fecr) (Fed-Feo) and activity index (Feo/Fed) showed significant differences (p<0.05) among soils from different locations. In the soils from Dobromirtsi, Parvenets, and Golyamo Kamenyane Ni bound to Fe oxides were evenly distributed between the well-crystallized and amorphous phases. In the soils from Kardzhali, Chernichevo and Dyulitsa more than half of the Ni bound to Fe oxides were bound to or occluded in amorphous Fe oxides, while in the soils from Kazak were bound to well-crystallized Fe oxides. Pedogenesis, weathering intensity, and Fe geochemistry influence Ni availability in serpentine soils.
State-specific morphological deformations of the lipid bilayer explain mechanosensitive gating of MscS ion channels
Authors: Park Yein Christina , Reddy Bharat , Bavi Navid , Perozo Eduardo , Faraldo-Gómez José D
Published: January 2023

The force-from-lipids hypothesis of cellular mechanosensation posits that membrane channels open and close in response to changes in the physical state of the lipid bilayer, induced for example by lateral tension. Here, we investigate the molecular basis for this transduction mechanism by studying the mechanosensitive ion channel MscS from Escherichia coli and its eukaryotic homolog MSL1 from Arabidopsis thaliana. First, we use single-particle cryo-electron microscopy to determine the structure of a novel open conformation of wild-type MscS, stabilized in a thinned lipid nanodisc. Compared with the closed state, the structure shows a reconfiguration of helices TM1, TM2, and TM3a, and widening of the central pore. Based on these structures, we examined how the morphology of the membrane is altered upon gating, using molecular dynamics simulations. The simulations reveal that closed-state MscS causes drastic protrusions in the inner leaflet of the lipid bilayer, both in the absence and presence of lateral tension, and for different lipid compositions. These deformations arise to provide adequate solvation to hydrophobic crevices under the TM1-TM2 hairpin, and clearly reflect a high-energy conformation for the membrane, particularly under tension. Strikingly, these protrusions are largely eradicated upon channel opening. An analogous computational study of open and closed MSL1 recapitulates these findings. The gating equilibrium of MscS channels thus appears to be dictated by opposing conformational preferences, namely those of the lipid membrane and of the protein structure. We propose a membrane deformation model of mechanosensation, which posits that tension shifts the gating equilibrium towards the conductive state not because it alters the mode in which channel and lipids interact, but because it increases the energetic cost of the morphological perturbations in the membrane required by the closed state.

Induced pluripotent stem cells (iPSCs) are potential cell sources for regenerative medicine. The iPSCs exhibit a preference for lineage differentiation to the donor cell type indicating the existence of memory of origin. Although the intrinsic effect of the donor cell type on differentiation of iPSCs is well recognized, whether disease-specific factors of donor cells influence the differentiation capacity of iPSC remains unknown. Using viral based reprogramming, we demonstrated the generation of iPSCs from chondrocytes isolated from healthy (AC-iPSCs) and osteoarthritis cartilage (OA-iPSCs). These reprogrammed cells acquired markers of pluripotency and differentiated into uncommitted mesenchymal-like progenitors. Interestingly, AC-iPSCs exhibited enhanced chondrogenic potential as compared OA-iPSCs and showed increased expression of chondrogenic genes. Pan-transcriptome analysis showed that chondrocytes derived from AC-iPSCs were enriched in molecular pathways related to energy metabolism and epigenetic regulation, together with distinct expression signature that distinguishes them from OA-iPSCs. Our molecular tracing data demonstrated that dysregulation of epigenetic and metabolic factors seen in OA chondrocytes relative to healthy chondrocytes persisted following iPSC reprogramming and differentiation toward mesenchymal progenitors. Our results suggest that the epigenetic and metabolic memory of disease may predispose OA-iPSCs for their reduced chondrogenic differentiation and thus regulation at epigenetic and metabolic level may be an effective strategy for controlling the chondrogenic potential of iPSCs.
Plasmodium infection disrupts the T follicular helper cell response to heterologous immunization

Naturally acquired immunity to malaria develops only after many years and repeated exposures, raising the question of whether Plasmodium parasites, the etiological agents of malaria, suppress the ability of dendritic cells (DCs) to activate optimal T cell responses. We demonstrated recently that B cells, rather than DCs, are the principal activators of CD4+ T cells in murine malaria. In the present study, we further investigated factors that might prevent DCs from priming Plasmodium-specific T helper cell responses. We found that DCs were significantly less efficient at taking up infected red blood cells (iRBCs) compared to soluble antigen, whereas B cells more readily bound iRBCs. To assess whether DCs retained the capacity to present soluble antigen during malaria, we measured responses to a heterologous protein immunization administered to naïve mice or mice infected with P. chabaudi. Antigen uptake, DC activation, and expansion of immunogen-specific T cells were intact in infected mice, indicating DCs remained functional. However, polarization of the immunogen-specific response was dramatically altered, with a near-complete loss of germinal center T follicular helper cells specific for the immunogen, accompanied by significant reductions in antigen-specific B cells and antibody. Our results indicate that DCs remain competent to activate T cells during Plasmodium infection, but that T cell polarization and humoral responses are severely disrupted. This study provides mechanistic insight into the development of both Plasmodium-specific and heterologous adaptive responses in hosts with malaria.

More than 50% of congenital hearing loss is hereditary, in which the majority form is non-syndromic. In this study we estimate the most prevalent pathogenic genetic changes in an Ossetian cohort of patients. This is useful for local public health officials to promote genetic counseling of affected families with regard to high allele frequencies of prevalent pathogenic variants and assortative mating in the community of people with hearing loss. In this study, genetic heterogeneity of hereditary non-syndromic sensorineural hearing loss (NSNHL) in a cohort of 109 patients and an assessment of the frequency of two GJB2 gene pathogenic variants in a cohort of 349 healthy individuals from the populations of the Republic of North Ossetia–Alania (RNO–Alania) were assessed. The molecular genetic cause of NSNHL in the GJB2 gene in RNO–Alania was confirmed in ~30% of the cases, including ~27% in Ossetians. In Russian patients, the most frequent variant is GJB2:c.35delG (~83%). The GJB2:c.358_360delGAG variant was found to be the most frequent among Ossetians (~54%). Two genetic variants in GJB2, c.35delG and c.358_360delGAG, accounted for 91% of GJB2 pathogenic alleles in the Ossetian patients. A search for large genome rearrangements revealed etiological cause in two Ossetian patients, a deletion at the POU3F4 gene locus associated with X-linked hearing loss (type DFNX2). In another Ossetian patient, a biallelic pathogenic variant in the MYO15A gene caused hearing loss type DFNB3 was identified, and in one Russian family a heterozygous MYH14 gene variant associated with dominant NSNHL was found. Thus, the informative value of the diagnosis was ~37% among all patients with NSNHL from RNO–Alania and ~32% among the Ossetians. These estimates correspond to the literature data on the fraction of recessive genetic forms of hearing loss within the affected population. The importance of this study consists not only in the estimation of the most prevalent pathogenic genetic changes in the Ossetian cohort of patients which could be useful for the public health but also in the genetic counselling of the affected families with regard to the high allele frequencies of revealed pathogenic variants as well as to the assortative mating in community of people with hearing loss.

A 2-year field experiment evaluated the effects of sweet corn-summer savory intercropping on crop productivity and essential oil (EO) composition of summer savory. Five cropping patterns of Corn 100%:Savory 0%, C75:S25, C50:S50, C25:S75, and C0:S100 were tested. The highest corn yield (2,440 kg ha−1) was obtained in a corn monoculture, but was not significantly different from C75:S25 or C50:S50. However, in both years the highest savory yield was obtained in S100 (793.3 g m−2 and 816.6 g m−2, respectively). Savory yields decreased as the proportion of corn increased. The land equivalent ratios in C25:S75, C50:S50, and C75:S25 were 1.54 ± 0.07, 1.56 ± 0.03, and 1.35 ± 0.1, respectively. Monocropped savory had the highest EO value followed by C25:S75 and C50:C50. However, no significant differences were found among these three treatments. Gas chromatography-mass spectrometry (GC–MS) analysis showed that the major components were carvacrol (35.88%–42.96%), γ-terpinene (18.45%–20.03%), ρ-cymene (11.77%–12.24%), and α-terpinene (2.75%–3.96%). The highest amount of carvacrol was recorded in C25:S75 (42.96%). This study suggests that intercropping of corn and savory represents an effective sustainable strategy, especially for smallholders, as a way to increase their overall land productivity and to improve the quality of savory’s EO.
