Published: March 2024

Contemporary lifestyles have given rise to many forms of entertainment. People are highly social and engage in various different activities to entertain themselves. They have increased access to social media where they can get a glimpse into the lives of their peers. Young adults especially, tend to partake in these activities. With such a lifestyle also come the negative emotions associated with missing out on events and comparing oneself to others. The objective of this study is to explore the relationship between FOMO (Fear of Missing Out) and Tendency to Maximize among Indian college students. This paper further investigates the individual and collective predictive capacity of Tendency to Maximize, Tendency to Regret and Social Comparison on FOMO. The study employed a survey method. Standardized questionnaires were administered to students from some of the metropolitan cities of India. The results indicate that there exists a significant positive correlation between Fear of missing out and Social comparison, Fear of Missing Out and Tendency to Maximize, as well as Fear of Missing Out and tendency to Regret. Furthermore, the study also found that there exists a significant difference in the experience of FOMO between Maximizers and Satisficers. Theoretical and quantitative findings are discussed in detail.

Pd(II)-Catalyzed Nondirected Late-Stage C(sp2)–H Deuteration of Heteroarenes Enabled Through a Multi-Substrate Screening Approach
Authors: Dey Jyotirmoy , Kaltenberger Simon , van Gemmeren Manuel
Published: March 2024

The importance of deuterium labelling in a variety of applications, ranging from mechanistic studies to drug-discovery, has spurred immense interest in the development of new methods for its efficient incorporation in organic, and especially in bioactive molecules. The five-membered heteroarenes at the center of this work are ubiquitous motifs in bioactive molecules and efficient methods for the deuterium labelling of these compounds are therefore highly desirable. However, the profound differences in chemical properties encountered between different heteroarenes hamper the development of a single set of broadly applicable reaction conditions, often necessitating a separate optimization campaign for a given type of heteroarene. In this study we describe the use of a multi-substrate screening approach to identify optimal reaction conditions for different classes of heteroarenes from a minimal number of screening reactions. Using this approach, four sets of complementary reaction conditions derived from our dual ligand-based palladium catalysts for nondirected C(sp2)–H activation were identified, that together enable the deuteration of structurally diverse heteroarenes, including bioactive molecules.

Mixed community microalgal wastewater treatment technologies have the potential to advance the limit of technology for biological nutrient recovery while producing a renewable carbon feedstock, but a deeper understanding of their performance is required for system optimization and control. In this study, we characterized the performance of a 568 m3·day-1 Clearas EcoRecover system for tertiary phosphorus removal (and recovery as biomass) at an operating water resource recovery facility (WRRF). The process consists of a (dark) mix tank, photobioreactors (PBRs), and a membrane tank with ultrafiltration membranes for the separation of hydraulic and solids residence times. Through continuous on-line monitoring, long-term on-site monitoring, and on-site batch experiments, we demonstrate (i) the importance of carbohydrate storage in PBRs to support phosphorus uptake under dark conditions in the mix tank and (ii) the potential for polyphosphate accumulation in the mixed algal communities. Over a 3 month winter period with limited outside influences (e.g., no major upstream process changes), the effluent total phosphorus (TP) concentration was 0.03 ± 0.03 mg-P·L-1 (0.01 ± 0.02 mg-P·L-1 orthophosphate). Core microbial community taxa included Chlorella spp., Scenedesmus spp., and Monoraphidium spp., and key indicators of stable performance included near-neutral pH, sufficient alkalinity, and a diel rhythm in dissolved oxygen.
Defluorination of HFCs by a Magnesium Reagent
Authors: Sheldon Daniel , Parr Joseph , Crimmin Mark
Published: March 2024

Reaction of a series of HFCs with a nucleophilic main group reagent containing a Mg–Mg bond results in defluorination to form the corresponding magnesium fluoride complex. In the case of 1,1,1,2-tetrafluoroethane (HFC-134a) generation of the fluoride occurs alongside selective formation of 1,1-difluoroethene. This is a highly unusual reactivity pattern for HFC-134a, which more commonly reacts by deprotonation and HF elimination. DFT calculations have been carried out to better understand the selectivity and compare the barriers for sp3 C–F bond activation with sp3 C–H bond activation in this system.
Colorimetric detection of fentanyl using a supramolecular displacement assay

Published: March 2024

Fentanyl is a potent synthetic opioid with an alarmingly low lethal dosage of 2 mg. The equipment necessary to detect fentanyl in field settings (e.g., handheld spectrometers) is restricted to highly trained, well-funded, and specialized personnel. Established point-of-need technologies, such as lateral flow immunochromatographic strips, are available; however, they often involve multiple contact-based steps (e.g., collection, mixing) that pose a higher risk to users handling unknown substances. Herein, we developed a colorimetric displacement assay capable of contactless detection of fentanyl as liquid or solid samples. The basis of our assay relies on the presence of fentanyl to displace a redox mediator, ferrocene carboxylic acid, inclusively bound in the cavity of a supramolecular host, CB[7]. The displacement is only possible in the presence of high affinity binding guests, like fentanyl (KA ~ 106 M-1). The liberated redox guest can then react with indicator reagents that are free in solution, producing either: (i) a distinct blue color to indicate the presence of fentanyl or (ii) remain a pale blue tint in the absence of fentanyl. We demonstrate rapid and specific detection of fentanyl free base and fentanyl derivatives (e.g., acetyl fentanyl, furanyl fentanyl) against a panel of 9 other common drugs of abuse (e.g., morphine, cocaine, heroin). Furthermore, we highlight the intended use of this assay by testing grains of fentanyl derivatives on a surface with a drop (i.e., 25 µL) of assay reagent. We anticipate this approach can be applied broadly to identify the presence of fentanyl at the point of need.
Dilithium phthalocyanine - A Single Ion Transport Interfacial layer for Solid-State Lithium Batteries
Authors: Chesta Chesta , Kalleshappa Bindu , Srinivasan Sampath
Published: March 2024

All-solid-state batteries possess several advantages including high safety, flexibility to use high-capacity metal anodes and are projected to be the next generation energy storage devices. Garnet-type cubic Li7La3Zr2O12 (LLZO) solid electrolyte is of particular interest due to its high ionic conductivity under ambient conditions and compatibility with Li metal. However, large electrode/electrolyte interfacial resistance constraints their development. Herein, the use of a highly lithium ion conducting dilithium phthalocyanine (Li2Pc) as an interlayer is proposed to effectively suppress the high impedance at the interface thus improving the electrode-electrolyte contact. Fast Li+ mobility and high dielectric constant of dilithium phthalocyanine enhance the kinetics of Li+ transport across the interface. A significant reduction in overpotential and very stable stripping/plating cycling are observed in lithium symmetric cells upon introducing Li2Pc interlayer as compared to the use of bare tantalum doped lithium lanthanum zirconium oxide (LLZTO) electrolyte. Cells comprising interlayer-modified Li|LLZTO|LiFePO4 show high capacity with excellent cycling and rate capability. The performance of full cells using lithiated graphite and lithium titanate anodes has also been evaluated. This study presents a promising application of garnet electrolytes towards the advancement of solid-state lithium batteries.
Vendor-dependent mobile phase contaminants affect neutral lipid analysis in lipidomics protocols

Published: March 2024

Lipidomics is a well-established field, enabled by modern liquid chromatography mass spectrometry (LCMS) technology, rapidly generating large amounts of data. Lipid extracts derived from biological samples are complex and most spectral features in LCMS lipidomics datasets remain unidentified, colloquially termed lipidomics “dark matter”. In-depth analyses of triacylglycerol, diacylglycerol, and cholesterol ester species revealed the expected ammoniated and sodiated ions as well as 5 additional higher mass dark matter peaks. These additional peaks were of relatively high intensity and resulted from analyte adduction with alkylated amine contaminants from LCMS-grade methanol and isopropanol. Tandem MS (MS/MS) of adduct peaks yielded no lipid structural information, producing only an intense ion of the adducted contaminant. Analysis of bovine liver extract identified 33 neutral lipids with an additional 73 alkyl amine adducts. Removing alcohols in place for acetonitrile and methyl tert-butyl ether in the mobile phase resulted in a 60% decrease in neutral lipid annotations, but eliminated the formation of alkyl amine adducts. Analysis of LCMS-grade methanol and isopropanol from different vendors revealed alkyl amine adduct formation in one out of three different brands that were tested. Substituting solvents increased lipid annotations by 36.5% or 27.4%, depending on the vendor and resulted in >2.5-fold increases in peak area for neutral lipid species, dramatically affecting their quantification and detection. Using principal component analysis, the same bovine liver sample separated into vendor-based clusters. These findings demonstrate the importance of solvent selection and disclosure during lipidomics protocols and highlight the challenges when comparing data between experiments.
Insight into Stable, Concentrated Radicals: from Sulfur-functionalized Alkyne-rich Crystalline Frameworks to Simple Alkyne Motifs

Published: March 2024

Organic radicals feature versatile unpaired electrons key for photoelectronic and biomedical applications, but remain difficult to access in stable concentrated forms. We disclose easy generation of stable, concentrated radicals from various alkynyl phenyl motifs, including 1) sulfur-functionalized alkyne-rich organic linkers in crystalline frameworks; 2) the powders of these molecules alone; 3) simple diethynylbenzenes. For Zr-based framework, generation of radical-rich crystalline framework was achieved by thermal annealing in the range of 300‒450 °C. For terminal alkynes, electron paramagnetic resonance signals (EPR; indicative of free radicals) arise after air exposure or mild heating (e.g., 70 °C). Further heating (e.g., 150 °C for 3 hours) raises the radical concentrations up to 3.30 mol kg‒1. For the more stable internal alkynes, transformations into porous radical solids can also be triggered, albeit at higher temperatures (e.g., 250 to 500 °C). The resulted radical-containing solids are porous, stable to air as well as heat (up to 300‒500 °C) and exhibit photothermal conversion capacity. The formation of radicals can be ascribed to extensive alkyne cyclizations, forming defects, dangling bonds and the associated radicals stabilized by the polycyclic π-systems.

Mempertanyakan Teodisi: Teodisi Yahudi Sesudah Auschwitz dalam Telaah Zachary Braiterman
Authors: Rahayu Ruth Indiah
Published: March 2024

The 20th century holocaust against Jews in Auschwitz, Buchenwald, and other concentration camps was the starting point for the change in modern Jewish theology towards contemporary theology. Contemporary Jewish theologians, rabbis, and philosophers have revisited their theodicy by critically reading scriptural texts and traditions (Midrash). The substance debated in theodicy is about God’s goodness which is in conflict with God’s omnipotence so that evil and suffering occur. The problem of Jewish theodicy after Auschwitz was studied by Zachary Braiterman by explaining the split between the hegemony of Jewish theodicy with a religious discourse and anti-theodicy with a pagan discourse. Braiterman uses a postmodern approach to map the criticism of Jewish theologians and philosophers towards the universal truth of theodicy before Auschwitz. This new discourse is useful for transforming the cultural changes of modern Jewish society from its marginal position in the text to becoming the main figure (anthropodicy). It seems that Braiterman is supporting the anti-theodicy movement to move beyond the nightmare of the holocaust in order to free the Jewish people from suffering by critically rereading texts and tradition.
Persepsi Identitas Diri sebagai Anggota Gereja di Kalangan Orang Muda Katolik
Authors: Junaedi Paulus Juju
Published: March 2024

The issue of identity as a member of the Church comes to the fore and is purified when placed within the framework of diversity and relationships with other ecclesiastical communities. Ecumenism is an effort to restore the unity of the Christian Church that emerges from the diversity of the Christian communities. In this case, identity as a member of a particular Church can actually grow and be enriched by these relationships. This article explores the self-perception of young Catholics as members of the Catholic Church amidst the diversity of the ecclesiastical communities. Using Paul Murray’s concept of Catholic learning, it observes how young people discover the uniqueness of their existence as members of the Catholic Church. Within this perspective, the Church instills an attitude of mutual respect and acceptance of the elements of truth within the Church itself and within other ecclesiastical communities. The author observes the ways of carrying out the Catholic learning by conducting an exploration of perceptions of self-identity among the Catholics, which aim to build an attitude of mutual respect, mutual acceptance, and mutual enrichment of each other. In this effort, the focus is directed towards young people who can be expected to witness as well as to learn from other ecclesiastical communities and that dialogue can be a means of purifying their identity.

Published: March 2024

Liquid smoke (LS) is getting more attention in many applications, especially food
preservation. However, there is still a big problem with the purity of LS. The objective of
this study is to improve the quality of LS using membrane filtration. The filtrations were
conducted using ultrafiltration or nanofiltration membrane at various pressures. The
quality of LS before and after filtration was compared based on their appearance. During
the filtration process, LS changed from a dark yellow fluid with a pungent odor to a pale
colorless substance with a less smokey odor and a slightly sweet aroma. The color and
fragrance parameters of LS before and after filtration using UF membranes were not
significantly different. NF membrane filtering had the opposite effect on the appearance of
LS. Chemical composition of volatile fraction was studied by GC/MS. Phenols were the
predominant aromatic chemicals found in all samples, with LS containing up to 80.8%,
17.53% in treated LS by UF membrane (2 bars), and 48.31% in NF membrane (5 bars).
The results proved that the membrane processing can eliminates potentially toxic
compounds while still imparting the desired flavors and pleasent aromas of LS.

Published: March 2024

This work aims to automatically control a wheeled robot from a specific location A to another B. We assume the robot’s trajectory is straight (the line (AB)). To solve this problem, we need the coordinates of point A and point B, i.e., the position sensor's state. A microcontroller must then process this information. Next, the variation in coordinates mean displacement, and this variation depends on speed, so we also interest in speed here. Finally, for the robot to arrive at point B, its direction of movement must be the same as the direction of (AB). The direction depends on the orientation angle of the moving robot.
Transitional Sensory-Scapes
Authors:   , Lauv Ethan
Published: March 2024

Mental health issues are an increasing problem worldwide and have yet to be addressed in the design world within the context of urban city environments. The pace of urban densification and the environments it creates neglect the impacts on human health. Within the urban environment, daily routines become monotonous, involving a relentless bombardment of sensory stimuli. Sensory overloading factors, such as unpleasant odours, erratic movement, and chaotic noises, have the potential to trigger mental health issues or fear.

This thesis delves into the mental health implications stemming from the sensory-overloading urban landscape. Using a research-through-design methodology, this study addresses the importance of 'healing/therapeutic' landscape spaces in the urban environment conversation. By combining elements of landscape architecture and literature focused on sensory implications and mental health impacts, this thesis aims to create a public space that offers respite. This would enable individuals to temporarily disconnect from their overwhelming sensory surroundings as well as desensitise their senses.

Authors: Hasyim Mohamad Yusuf Ahmad , Susilo Bernandus Wahyudi Joko , Jamil Jamat
Published: March 2024

In this epidemic era, teachers are expected to build a successful learning environment in conjunction with online learning. Basic nahwu learning is one of the lessons affected by the pandemic situation. Learning the Arabic language system is increasingly difficult to do online because the Arabic language system is very different from Indonesian, as the learners' mother language. The presentation of linguistic rules clearly cannot be done directly. Educators are responsible for innovating nahwu learning through the unity-based Nahma educational game "Nahwu Matching" so that learners can easily understand and avoid boredom during the full online learning. The use of educational games is the right solution to overcome this problem. The aims of this study are: (1) to find out the needs of lecturers and students, (2) to describe the prototype picture of the Nahma. The data of this study were obtained through test and non-test data. The tool of the test is a written test while tools of the non-test data are interviews, observations, and questionnaires on the needs of lecturers and students. Based on the findings, it can be stated that both students and teachers require engaging learning applications for Nahwu that can successfully assist the learning process.
A violência contra a mulher na literatura contemporânea argentina
Authors: Montebelo Barcelos Carolina
Published: March 2024

De acordo com o Observatório de Igualdade de Gênero da América Latina e do Caribe, em 2021, 11 países registraram uma taxa de feminicídio superior a uma vítima por cada 100.000 mulheres, estando a Argentina na terceira posição do ranking em números absolutos, precedida pelo Brasil e pelo México. Destarte, a literatura latino-americana contemporânea vem reverberando a violência de gênero como ponto central das narrativas. Desse modo, examinam-se, neste artigo, duas produções literárias argentinas: a novela Le viste la cara a Dios, de Gabriela Cabezón Cámara, e o romance Garotas mortas, de Selva Almada. Para fins de suporte teórico, são cotejados com os textos literários análises da violência contra a mulher e do feminicídio levadas a cabo pelas antropólogas Rita Laura Segato, Marcela Lagarde y de Los Ríos e Esther Pineda, assim como pela teórica Diana Russell. Nas considerações finais é discutido, tendo como base os textos literários analisados, como a estrutura patriarcal arraigada na sociedade latino-americana é responsável pela violência de gênero.

Published: March 2024

O governo de Juscelino Kubitschek (JK) é amplamente estudado, dada sua relevância para o processo de industrialização do Brasil. A pauta de desenvolvimento social não estava inserida diretamente no plano de governo de JK, pois acreditava-se que o crescimento econômico ocasionado pelo Plano de Metas sanaria organicamente os problemas sociais. Portanto, este trabalho visa analisar a distribuição de renda, educação e saúde durante o plano de metas utilizando análise descritiva de séries históricas dos gastos públicos e indicadores sociais do período. Observou-se que a educação e saúde tiveram melhorias pouco significativas, enquanto a desigualdade de renda se agravou no período.

Published: March 2024

Assume-se neste ensaio a tarefa de pronunciar as bases filosóficas da obra de Milton Santos, nomeadamente nas matérias que possam contribuir para uma revisão epistemológica de elementos fundamentais para as novas teorias do desenvolvimento, quais sejam: o espaço, a materialidade, a temporalidade, a técnica e, especialmente, o humanismo. Nesse caminho, dá-se uma atenção especial às concepções que desembocam na sua tese sobre a Formação Econômica, Social e Espacial. Por outro prisma, busca-se evidenciar importantes filiações às teorias e escolas de pensamento como as do materialismo histórico, do existencialismo e do evolucionismo, manifestando evidentes relações com as novas concepções desenvolvimentistas baseadas na liberdade e nos direitos econômicos, políticos, civis e culturais.

Борьба с блуждающими токами на сегодняшний день остается актуальной проблемой при электрохимической защите подземных магистральных трубопроводов. Практика показывает, что установки дренажной защиты, работающие совместно со станциями катодной защиты, не всегда эффективны. Для обеспечения безопасной эксплуатации подземных трубопроводов требуется поддерживать защитный потенциал в определенном диапазоне – между нормативными минимальным и максимальным значениями. В зоне действия блуждающих токов потенциал выходит за рамки максимальных значений, приводя металл в перезащищенное состояние. Проведенные лабораторные исследования показали, что повышение токовой нагрузки на установке дренажной защиты приводит к увеличению тока, вырабатываемого станцией катодной защиты. Анализ системы электрохимической защиты на реальном объекте (участке магистрального трубопровода) показал, что защитный потенциал в точке дренажа сдвигается в отрицательную сторону, создавая условия для перезащиты, на обеих установках. С целью устранения перезащищенного состояния трубопровода предложена модифицированная установка усиленного дренажа с использованием протяженного гибкого анода.

To this date, protection against earth currents is an urgent problem for electrochemical protection of the main underground pipelines. Experience has shown that the drainage protection installations operating together with the cathodic protection stations are not always efficient. To ensure safe operation of the underground pipelines, the protective potential shall be maintained within a certain range, between the regulatory minimal and the maximum values. Within the area of earth currents action, the potential goes beyond the maximum values, thus bringing metal to an overprotected state. The laboratory tests performed demonstrated that an increase of the current load on the drainage protection installation results in an increase of the current generated by the cathodic protection station. Analysis of the electrochemical protection system at the real facility (the main pipeline section) showed that the protective potential at the drainage point is shifted to the negative side, thus creating the conditions for overprotection at both installations. To eliminate the overprotected state of the pipeline, the modified intensive drainage installation with the use of the stretched flexible anode was suggested.

The present study aimed to understand the relationship between mindfulness, mental imagery, and subjective sports performance satisfaction. This study was done on male tennis players aged 18 to 28 years who play competitive tennis at the State and National Levels in India. The tools used to measure the variables were The Mindfulness Attention Awareness Scale (MAAS) by Brown & Ryan (2003), Sports Imagery Ability Questionnaire by Williams & Cumming (2014) and Athlete’s Subjective Performance Scale (ASPS) by Nahum et al. (2016). The results of the study show that the national-level tennis players had better self-reported satisfaction scores than the state-level players. Zero-order correlations showed that there was a statistically significant, moderate, positive correlation between Mindfulness and mental imagery (r(53) = -.304, n = 55, p < .05), indicating that subjective sports performance satisfaction had very little influence in controlling for the relationship between Mindfulness score and mental imagery.

Natural regeneration of black pepper (Piper guineense Schumach and Thonn) through seeds is poor and cultivation by local farmers is very limited since it is usually collected from the wild. High demand has put a pressure on its population in our declining forests and a call for domestication of non-timber forest plant species is ongoing. This study identified germination requirements, germination characteristics and seedling growth of Piper guineense with a view to providing information on its propagation from seeds. There were two major pre-sowing treatments - Fresh or dry fruits or seeds. Germination and seedling growth parameters were measured for all treatments. Results showed that Piper guineense seeds undergo epigeal germination, the radicle developing into three-legged hairy rootlets. The highest percentage germination, germination rate and germination index were recorded in the treatment with fresh seeds planted in petri dish. The dry seeds and fruits recorded no germination even after 38 days of planting. For seedling growth, the developing leaves have a higher sink strength between the fourth and fifth month of development and this stage may be crucial to the growth of the seedling. Piper guineense seeds must be sown fresh for germination to take place.

This study aims to determine the decrease in glucose levels, MDA levels, and histopathological appearance of the pancreatic organs of Wistar white rats after administration of the ethanol-water fraction of longjack root. This study used a completely randomized design with four treatment groups and six replications. The treatment consisted of normal control, negative control (Na-CMC 0.5% 5 ml/200 g body weight), positive control (glibenclamide 0.09 mg/200 g body weight), and treatment of the ethanol-water fraction of longjack root with a dose of 500 mg/kg body weight. The results showed that the ethanol-water fraction of longjack root at a dose of 500 mg/kg body weight had antidiabetic activity comparable to that of glibenclamide at a dose of 0.09/200 g body weight, namely blood glucose levels and MDA levels in white rats of 123.55 mg/dl and 2.83 nmol/ml. The results of histopathological analysis of the pancreas of white rats showed that administration of the ethanol-water fraction of longjack root could repair damage to the islets of Langerhans due to the administration of streptozotocin-nicotinamide.

Critical thinking includes higher processes, such as analysis, synthesis, evaluation, conclusion, and reflection. This research aims to determine the profile level of students' critical thinking abilities. The research sample consisted of 28 students taken by random sampling consisting of 2 classes. Data was obtained through test and non-test techniques which included a critical thinking ability test using 20 questions. Meanwhile, the non-test uses an observation sheet on students' critical thinking abilities. Analysis of data obtained from the results of students' critical thinking skills tests was then analyzed using analysis items with the Rasch model. The results of the profile analysis of students' critical thinking skills were classified as moderate. This is proven by test results and observations in basic biology courses. Based on the results of tests on students' critical thinking skills, it is known that there are 16 students who have high levels of critical thinking skills, 5 students with moderate critical thinking skills, and 6 students with weak critical thinking skills. Meanwhile, the results of observations of the critical thinking abilities of Bima Muhammadiyah University students in basic biology courses are in the moderate critical thinking ability category with a category score of around 68.06%.
