Authors: Bercasio Rebecca Rosario
Published: June 2023

This study aimed to enrich Grade 6 English lessons with GCED using local and global issues in the GCED integration in the lessons.  Conducted in a public school in the Philippines during the school year 2019-2020, the study used the descriptive method and triangulation method and data sources triangulation. The specific objectives of the study are: (1) Identify phenomena suggested for GCED-enriched Grade 6 English lessons; (2) Develop GCED-enriched lessons in Grade 6 English using a phenomenon-based learning approach; (3) Identify the teaching strategies used in the GCED integration; and (4) Identify the teacher's insights based on his experiences in implementing the lessons. Methods for data collection were documentary analysis of the phenomenon-based GCED-enriched Grade 6 lessons,   focus group discussion, workshop, in-depth individual interviews (IDI), analysis of teacher’s reflection notes, and class observations. The suggested phenomena consisted of local and global issues focusing on environmental and climate change, gender and development, identity and diversity, government and politics, and peace and conflict. The grade 6 English lessons can be easily integrated with GCED using local and global phenomena. Varied strategies that are aligned with phenomenon-based learning and active learning can be used for teaching English enriched with GCED. The teacher's insights on the teaching of GCED in Grade 6 English lessons using local and global phenomena can serve as a useful and practical guide in the design and implementation of GCED-enriched lessons. Implementing a whole-school approach to embracing GCED and action options to promote GCED in instructional practices are recommended.

Published: June 2023

Introduction. Ensuring safe working conditions and preventing health problems in the workplace is a priority measure for maintaining health and extending the working life of the working population.
Materials and methods. The working conditions and chronic non-infectious morbidity (primary, accumulated) of workers in the production of polyacrylonitrile (PAN) fibers were studied according to the data of in-depth medical examinations (2017–2021).
Results. Workers of modern production of PAN fibers in the course of their work were shown to be exposed to the combined effects of a complex of chemicals of 1–4 hazard classes, industrial noise, severity and labour intensity, which form an occupational health risk, assessed by hygienic criteria in categories from small (class 3.1) to high (class 3.3). The first ranking places in the nosological structure of accumulated chronic non-infectious morbidity of workers were occupied by dorsalgia (24.23%), essential (primary) arterial hypertension (14.67%), obesity (9.9%) and presbyopia (8.87%). Positive associations of weak age strength with arterial hypertension, obesity, and presbyopia were revealed (Rxy=0.280, Rxy=0.121, Rxy=0.133, respectively). Work experience had a weak positive relationship with the prevalence of presbyopia (Rxy=0.239). A causal relationship was established between a moderate degree of diseases of the musculoskeletal system and connective tissue (dorsalgia, the severity of the labour process (RR=1.893; EF=47.183%; CI=1.192–3.007), a relationship between a small degree of diseases of the eye and its adnexa with exposure acrylonitrile and methyl acrylate (RR=1.46; EF=31.522%; CI=1.970–1.082), which made it possible to attribute these pathologies to work-related diseases.
Limitations determined by the study of the subject of research in the production of polyacrylonitrile fibers of one enterprise.
Conclusion. Despite the modernization that has taken place in the chemical industry, working conditions in the modern production of PAN fibers continue to be harmful, presenting an occupational risk for the development of chronic non-communicable diseases in workers, which determines the relevance of developing evidence-based measures for their prevention.

Published: June 2023

Este artículo es producto de una investigación que se llevó a cabo durante el 2021 y tiene como objetivo identificar los principales impactos y retos de las ingenierías industriales (Industrial y en Producción Industrial) costarricenses en la Revolución 4.0 del país; es importante tomar en cuenta que la industria 4.0 es un suceso global, evento que modifica la industria y transforma la vida de las personas; es tal esta evolución, que influye incluso en la manera de obtener el conocimiento. Algo que parece mantenerse inmutable y preponderante, respecto a todas las anteriores revoluciones, es que el talento humano sigue siendo el factor más importante. Se articulan históricamente tres ejes para el desarrollo de cualquier comunidad; la sociedad, la industria y la academia. En este sentido las universidades, tienen el compromiso ineludible de disminuir la "brecha digital", con la formación de profesionales “integrales” idóneos para que la sociedad y la industria dispongan de estos. De tal manera que las universidades públicas deban ajustar su currículo y acoplar sus aulas a la verdad de la industria 4.0, al incorporar Big Data, Robots, Simulación, Integración universal de sistemas, IOT industrial, seguridad cibernética, computación en nube, fabricación aditiva y realidad aumentada, etc., con el fin de ajustarse más a la realidad y a la formación de los profesionales que realmente requiere el país. Respecto a los resultados, las universidades públicas que gradúan profesionales en Ingeniería en Producción Industrial presentan la menor diferencia de graduados por género, ya que el 48 % de estos diplomas lo obtuvieron mujeres. Al respecto, el 59 % de todos los títulos generados en ambas carreras (2014-2021) son diplomas de bachillerato. Paralelamente, el análisis posibilitó establecer una relación entre el número de personas graduadas en las universidades costarricenses y el comportamiento del PIB.

Authors: Ganeshamoorthy Kajenthini
Published: June 2023

Good governance can improve government expenditure efficiency and lead to better human development outcomes in education and health. The paper aims to shed light the influence of governance in determining public spending's efficacy in improving health outcomes in Sri Lanka. To find the study objectives, Augmented Dickey-Fuller unit root test, Johansen’s co-integration tests, and the Vector Error Correction Model were employed using time series data. The results confirmed that government expenditure on health without its interaction of governance indicators positively influences health status in the long term. Likewise, government expenditure on health and its interaction with governance indicators, namely corruption and government effectiveness, negatively influences health status in the long term in Sri Lanka. In contrast, government expenditure on health and its interaction with the rule of law positively impact health status. Besides, in the short run, government health expenditure positively impacts health status while governance indices with government expenditure were not influenced the health status. In Sri Lanka, where the effectiveness of public spending on health with the interaction of governance is comparatively low. Therefore, the current study stresses that the governance of Sri Lanka should be improved to enhance the effectiveness of public spending with good governance in order to improve the health outcomes.

Soon after the pandemic inflicted by Covid-19 was declared, different organizations and smart application development companies suggested that artificial intelligence could be an useful tool in helping the medical staff monitoring the virus spread for a better understanding of its behavior. This paper presents a smart application CovidWatch developed for users real-time warning regarding the possibility of contracting the Sars-CoV-2 virus from an infected person. For this purpose, the developed application uses the Bluetooth module of the user’s device in order to check the social distance and to determine the possible contacts. The developed application has a number of four modules (the expert system (ES), the data retrieval, the real-time information and warning and the interface), that work on Android devices. Using the artificial intelligence techniques (knowledge-based systems), the application has a knowledge base populated with user’s data, the user’s time of contact and distance and the users identified as being contacts. If a user warns the android application that he has been infected with Covid-19, it further triggers the expert system inference engine, allowing the knowledge to be inferred. Based on the implemented rules, the inference engine analyses the data regarding the users that were in contact with an infected person. If those meet the conditions taken into consideration for declaring a person as being contact (a certain distance and time) they receive in real time a warning message and some advice regarding how it is recommended to act. The main advantage of android application is that it provides real-time warning regarding the possibility or probability of being infected with Covid-19, warning that can be deactivated only after the user has confirmed that the took note of this. A set of CovidWatch application simulation results is also presented taking into consideration different scenarios.

Published: June 2023

"Around half of the total carbonate rocks of Romanian territory are Upper Jurassic-Lower Cretaceous age. Most of them are able to develop karst phenomena. In the southern-central part of the Moesian Platform Jurassic-Cretaceous deposits are at 2000-3000 m depth. The existence of the hydrocarbon accumulations in the area was just proved (Talpa, Harlesti, Videle fields). In the calcareous deposits, the seismic profiles and the attributes of seismic traces highlighted some specific geological features: The collapse karst areas, formed in Jurassic-Neocomian deposits. The seismic expression of these areas is one of chaotic reflections zone flanked by converging, strong tilted faults. The paleo-valley systems formed by erosion of the Cretaceous relief, filled with different terms of the Lower Sarmatian (a succession of marls and sands). The reflections configuration is specific to the passing from the valley fill lithology to the Cretaceous calcareous formations of the adjacent areas. The reef build-ups in Upper Jurassic-Lower Cretaceous formations, expressed by chaotic reflection mound zones draped for quasi horizontal superimposed strata. The seismic trace attributes and velocity analyses are important tools in reservoir quality definition, giving information regarding porosity and fluid contents. "

Dilute and dense conveying systems through pipelines are a common practice in our everyday life. It is used in many industries to convey a mixture of gas and solids from one location to another through pipes. Gas-solid transport is desirable in some industries but unwanted in others. Depending on the density, size, and shape, these solid particles may result in erosion and subsequent damage to piping and other equipment. Understanding the gas-solid two-phase flow dynamics can help develop efficient and cost-effective pipe transport systems, thereby mitigating the problems associated with the gas-solid two-phase flow. Models for estimating volumetric flow rates and other gas-solid two-phase flow properties are scarce as most are very complex, expensive, and unavailable proprietary commercial software. This study, therefore, developed a simple model using the general energy balance equation and relevant mixing theories for estimating the volumetric flow rate of natural gas-solid two-phase flow in horizontal pipes. The results from the model showed that the gas-solid flow rate is a function of pipe diameter, pressure drop, pipe length, solid volumetric concentration, solid-to-gas density ratio, and solid-to-gas friction factor ratio.

"The contribution of the combined interpretation of geo-petroleum data in the oil exploration program of the central Cuvette basin “case of the Lokoro sub-basin” carried out as part of our scientific research for Diplome d'Etudes Approfondies studies (DEA). The objective of this research is to update knowledge on oil exploration in the Lokoro sub-basin. We combined and analyzed geological, geochemical and geophysical data to obtain the following results: - Static terrestrial gravity campaign in the western part in order to have information on the sedimentary cover of this zone and the geological structures; - The Kiri structure is a salt dome superimposed by fragments of granitic rock which give a signature of heavy gravity anomaly; - The highlighting of three prospective zones, Zone A, Zone B and Zone C, for which we have proposed seismic work adapted to geological realities; - The L59 seismic line of the Dekesse well was not drilled in the right place, the interpretation of this profile shows the deformation by salt tectonics, which generated geological structures of oil interest, the location of which we had proposed drilling.

A PIGGY BACK separator is a device used in industrial oil and gas applications to separate a vapor-liquid mixture into its constituent phases. The aim of this study is to size the Piggy Back, a separator placed upstream of an electrostatic dehydrator to perform gas-liquid separation. In the course of this study, we sized the Piggy Back using manual calculations in accordance with the guidelines of the main standards and codes in force today, such as API 12J. To validate the manual assessment of the separator's dimensions, a static simulation was carried out using ASPEN HYSYS® software. Using the finally approved manual sizing methodology, and taking into account the Piggy Back separator's operational data, an economic evaluation was carried out to conclude that the design was cost-effective.

Oil polluted water is not rare on the Earth and treating it in energy efficiency way to be properly returned to the environment is of great interest. This work makes an analysis of several technologies and selects some of them to be included into a complex treatment system starting from polluted water found in various places on Earth to the level of being released in nature, or event to use the treated water in human activities. Several stages of treatment are set: solid separation, oil separation, remained water treatment, filtration and evacuation. Separation of solids is made with less used and more energy efficiency technology. Also, oil from water separation is made with a new and very efficient technology, permitting future recovery of the separated oil for energy or semi-green hydrogen production. After releasing solids and removable oil, the polluted water is treated in more efficient way with natural components and with no polluting output based on ozone, oxygen and nitrogen gases in nano-bubbles form. All gases are extracted from natural air and converted in strong reactors through equipment presented in the work. The nanobubbles treated water releases the reaction by-products as oxides of metals to be filtered and oxygen, hydrogen, nitrogen, CO2 gases to be released into the atmosphere before being clean to be released to the emissary.

Abstract. Black carbon (BC) is a short-lived climate forcer affecting Arctic climate through multiple mechanisms, which vary substantially from winter to summer. Several models still fail in reproducing BC seasonal variability, limiting the ability to fully describe BC climate implications. This study aims at gaining insights into the mechanisms controlling BC transport from lower latitudes to the Arctic lower troposphere. Here we investigate the drivers controlling black carbon daily and seasonal variability in the Arctic using Generalized Additive Models (GAM). We analysed equivalent black carbon (eBC) concentration measured at the Gruvebadet Atmospheric Laboratory (GAL - Svalbard archipelago) from March 2018 to December 2021. The eBC showed a marked seasonality with higher values in winter and early spring. The eBC concentration averaged 22 ± 20 ng m-3 in the cold season (November–April) and 11 ± 11 ng m-3 in the warm season (May–October). The seasonal and interannual variability was mainly modulated by the efficiency of wet scavenging removal during transport towards the higher latitudes. Conversely, the short-term variability was controlled by boundary layer dynamics, local-scale, and synoptic-scale circulation patterns. During both the cold and the warm season, the transport of air masses from western Europe and northern Russia was an effective pathway for the convey of pollution to the European Arctic. Finally, in the warm season we observed a link between the intrusion of warm air from lower latitudes and the increase in eBC concentration. Changes in synoptic scale circulation system and precipitation rate in the northern hemisphere, linked to climate change, are expected to modify BC burden in the Arctic.
Field experiments in ocean alkalinity enhancement research

Abstract. This chapter focuses on considerations for conducting open-system field experiments in the context of ocean alkalinity enhancement (OAE) research. By conducting experiments in real-world marine systems, researchers can gain valuable insights into ecological dynamics, biogeochemical cycles, and the safety, efficacy, and scalability of OAE techniques under natural conditions. However, logistical constraints and complex natural dynamics pose challenges for successful field trials. To date, only a limited number of OAE field studies have been conducted, and guidelines for such experiments are still evolving. Due to the fast pace of carbon dioxide removal (CDR) research and development, we advocate for openly sharing knowledge and lessons learned as quickly as possible within the broader OAE community and beyond. Considering the potential ecological and societal consequences of field experiments, active engagement with the public and other stakeholders is essential. Collaboration, data sharing, and transdisciplinary teams are vital for maximizing the return on investment during field trials. The outcomes of early field deployments are likely to shape the future of OAE, emphasizing the need for transparent and open scientific practices.

Published: June 2023

Abstract. We present laboratory experiments on the growth of a tubular ice structure surrounding a plume of cold brine that descends under gravity into water with a higher freezing point. Brinicles are geological analogues of these structures found under sea ice in the polar regions on Earth. They may be important for the energy budget of sea ice. Brinicles are hypothesized to exist in the oceans of other celestial bodies, and being environments rich in minerals, serve a potentially analogous role as an ecosystem on icy ocean worlds to that of submarine hydrothermal vents on Earth.

Abstract. In late March 2011, landfast sea ice (hereafter, ‘fast ice’) formed in the northern Larsen B embayment and persisted continuously as multi-year fast ice until January 2022. In the 11 years of fast ice presence, the northern Larsen B glaciers developed extensive mélange areas and formed ice tongues that extended up to 16 km from their 2011 ice fronts. In situ measurements of ice speed on adjacent ice shelf areas spanning 2011 to 2017 show that the fast ice provided significant resistive stress to ice flow. Fast ice breakout began in January 2022, and was closely followed by retreat and break-up of both the glacier mélange and the adjacent ice tongue areas. We investigate the probable triggers for the loss of fast ice and document the initial upstream glacier responses. Our results suggest that the fast ice loss was linked to strong wave action (>1.5 m amplitude) with long period swells (>5 s) that reached the embayment simultaneously with the appearance of rifts in the ice. This coincided with a 12-year low in sea ice concentration in the northwestern Weddell Sea. Remote sensing data in the months following the fast ice break-out reveals an initial ice flow speed increase (up to 333 %), elevation loss (9 to 11 m), and rapid calving of floating and grounded ice for the three main glaciers Crane (11 km), Hektoria (25 km), and Green (18 km).

Individual performance determinants and personal career motives are pivotal to all teaching and learning formats in higher education, especially with a view towards tailor-made study formats. While curricula provide opportunities to customize study formats, it seems that teachers in higher education have hitherto not fully exploited the potential for individualization at the level of lectures and seminars. Current teaching and learning in higher education is evidence-based, whence this empirical quantitative study aims to investigate personality traits and career motives of students in teacher programmes in comparison with students of other degree programmes.
