Published: July 2024

The cyclononatetraenyl (Cnt) ligand is a large monoanionic ligand. It is easily synthesized by ring expansion after cyclopropanation of the cyclooctatetraenyl (Cot) ligand. The Cnt ligand can be reported as the cis-cis-cis-cis (cis) isomer, where the aromatic ring is flat, and all carbon atoms form a homogenous ring, and as the cis-cis-cis-trans (trans) isomer, where one carbon places itself inside the ring. The isomerization from the trans to the cis form has been reported numerous times in previous articles, but no quantitative analysis has been proposed due to contradictory data. This article proposes a detailed analysis involving light in order to rationalize this intrigue concerning isomerization. A careful synthesis at low temperatures and with light protection yields the ligand in its trans form (Cnt-trans). The controlled photo-isomerization of the Cnt-trans ligand is reported herein. A series of divalent or trivalent rare earth complexes, (Cnt)2Sm, and (Cot)(Cnt)Ln (Ln= Y, La, Ce, Pr, Nd, Sm, Gd, Tb, Er, Ho), which synthesis, solid-state X-ray diffraction and solution 1H NMR and UV-Visible measurements, have been revised according to the synthesis using the Cnt-trans ligand. The photo-isomerization of the (Cnt-trans)2Sm evolves to the intermediate (Cnt-cis)(Cnt-trans)Sm and the (Cnt-cis)2Sm complex as the thermodynamical product. The photoisomerization of the trivalent (Cot)(Cnt)Ln complexes highlights the formation of a photostationary state (PSS) after several minutes of irradiation, in which both Cnt-trans and Cnt-cis ligands are present. The ratio of these two forms varies according to metal and irradiation wavelength: while low-energy wavelengths favor the cis isomer, high-energy wavelengths favor the trans isomer. DFT and TD-DFT were performed to provide a tentative orbital explanation.
Singing Homer’s Spell: The End of Oralist Poetics (Preface)
Authors: David A.P.
Published: July 2024

We did not use to know how the prosody of Greek words interacted with Greek metres. With the arrival of the new theory of the Greek accent, now we do. The ignoring of the seemingly irrelevant accent marks in texts seems to have led not to the realisation that all we could know, sadly, about the sound and performance of Greek poetry was its metre, but to the delusion that metre was all there was to know. The level of discovery newly achieved in the texture and the nature of Homeric composition is truly astounding, even to the author.
There is no embarrassment, however, because he can take no credit for the content of the treasury: the new law of tonal prominence is merely the key to opening a long silent vault, hidden in plain sight in the accentual notation of East Roman manuscripts. There are now unmistakable proofs—for so they should be called—of Homer’s musical intent and design. The implications for any theory of Homeric composition, and indeed any assessment of his artistic arsenal, can find no bottom, once these findings see the light of day. Most egregious is the hypothesis of an oral tradition shaping composition via purely metrical formulas, with no role whatsoever to be played by the manifest tonal phenomena recorded in the manuscripts. Penelope’s circumflexes, and her special circumflected motif, are a sight and a sound that can no longer be unseen, or unheard in their wake. Odysseus also is discovered to have a distinctive accentual motif (Chapter 11). Let the implications sink in like a down- glide in your voice: there is new music on the radio, and Homer must be heard as if for the first time.

Published: July 2024

Biodiversity is a fundamental part of sustainable development, but it is threatened by numerous factors related to population growth. The rapid urbanization of the world has a profound impact on global biodiversity, and urbanization is considered one of the processes contributing to the homogenization of the world's biota. Currently, there is an increase in the anthropogenic load on the biodiversity of the urban environment in the arid conditions of the Kazakh part of the Aral Sea region. This contributes to the development of a number of negative processes (transformation of components of the natural environment, violation of the ecological, socio-economic situation). As a result, there is a need to study the response of biological resources to anthropogenic impact, as well as to climate changes observed in the region. There is an urgent need to conduct comprehensive research aimed at studying and evaluating the pace of changes in species richness and diversity in the structure of the fauna and flora of the region. One of the indicators of environmental transformation is considered to be the bird fauna, due to its sensitivity to any changes in nature. Quantitative accounting of avifauna can serve as a reliable method for analyzing the sometimes subtle shades of changes in the composition of the bird fauna. Currently, there is a rapid increase in the horizontal area and the number of floors of buildings in the vertical direction in Kyzylorda. This makes an adjustment to the comfortable existence of the avifauna. There are no data on monitoring the avifauna of the city of Kyzylorda in the available literature. Taking into account the above, the authors of the project have attempted to conduct year-round bird counts within Kyzylorda since 2019. This scientific research was initiated for the purpose of an interim analysis of the results of scientific work.

Assessment of the ethanolic extract of Coccinia grandis on in vitro antityrosinase and anti-inflammatory activities and its active chemical
determination
Authors: Chuchote C. , Somwong P.
Published: July 2024

Cucurbitaceae plants have figured prominently in the world as edible medicinal plants,
supplying essential elements and minerals to support human health and prevent some
diseases caused by malnutrition. Coccinia grandis (L.) Voigt, also known as the ivy
gourd, is one of the most popular cucurbitaceous plants that has spread throughout the
tropics. For a long time, the plant has been cultivated as a food crop, and its aerial parts
have been used as nutritious vegetables. Coccinia grandis extract has been scientifically
reported to be efficient in various pharmacological investigations such as antioxidant,
antimicrobial, and cell proliferative properties, and it was recently affirmed as a potential
medicinal herb with antidiabetic properties. This suggests that developing plant extracts as
functional ingredients in food and medicine is more advantageous. Thus, the goal of this
study was to elaborate on previously unreported pharmacological activities as well as to
identify the active phytochemical compound responsible for their action. In this study, C.
grandis ethanolic extract was confronted with a variety of in vitro biological assays,
including tyrosinase inhibition activity and anti-inflammatory activity. When compared to
the positive controls, the plant extract displayed remarkable anti-tyrosinase activity with
an IC50 value of 0.29±0.06 mg/mL and anti-inflammatory activity with an IC50 value of
9.63±1.10 mg/mL. The active triterpenoid compound lupeol was found in the sample at a
level of 18.87±0.79 mg per 100 g of dry extract, as shown by the HPLC profile of the
extract. The current study demonstrated the presence of an active chemical in C. grandis
extract, which could support the prospect of integrating this extract into herbal food
products that become beneficial to health.

Authors: Jeddi Camillia
Published: July 2024

3,4-Methyl​enedioxy​methamphetamine (MDMA), is a synthetic amphetamine derivative. Its usage can be complicated by intracerebral or subarachnoid hemorrhage. Drug-related intracranial hemorrhage (ICH) is a relatively uncommon occurrence, often associated with an underlying vascular anomaly,
We report the case of a 28-year-old male with a history of Ecstasy abuse prior to the onset of a sever holocranial headache. Cerebral computed tomography angiography revealed a right sided sub-arachnoid hemorrhage and blood within all four ventricles, as well as a right sided pontine hematoma and an arteriovenous malformation.
As the drug epidemic continues to worsen, it is important to take a full drug history in patients presenting with a severe headache, and to not overlook ICH as a potential complication of recreational drug abuse.

Decrease in active hepatitis C infection among people who use drugs in Madrid, Spain, 2017 to 2023: a retrospective study
Authors: Ryan Pablo , Valencia Jorge , Cuevas Guillermo , Amigot-Sanchez Rafael , Martínez Isidoro , Lazarus Jeffrey V , Pérez-García Felipe , Resino Salvador
Published: July 2024

Background

People who use drugs (PWUD) are a key target population to reduce the burden of hepatitis C virus (HCV) infection.

Aim

To assess risk factors and temporal trends of active HCV infection in PWUD in Madrid, Spain.

Methods

We conducted a retrospective study between 2017 and 2023, including 2,264 PWUD visiting a mobile screening unit. Data about epidemiology, substance use and sexual risk behaviour were obtained through a 92-item questionnaire. HCV was detected by antibody test, followed by RNA test. The primary outcome variable was active HCV infection prevalence, calculated considering all individuals who underwent RNA testing and analysed by logistic regression adjusted by the main risk factors.

Results

Of all participants, 685 tested positive for anti-HCV antibodies, and 605 underwent RNA testing; 314 had active HCV infection, and 218 initiated treatment. People who inject drugs (PWID) were identified as the main risk group. The active HCV infection rate showed a significant downward trend between 2017 and 2023 in the entire study population (23.4% to 6.0%), among PWID (41.0% to 15.0%) and PWUD without injecting drug use (7.0% to 1.3%) (p < 0.001 for all). These downward trends were confirmed by adjusted logistic regression for the entire study population (adjusted odds ratio (aOR): 0.78), PWID (aOR: 0.78), and PWUD non-IDU (aOR: 0.78).

Conclusions

Our study demonstrates a significant reduction in active HCV infection prevalence among PWUD, particularly in PWID, which suggests that efforts in the prevention and treatment of HCV in Madrid, Spain, have had an impact on the control of HCV infection.

In this paper, we introduce a regression model using dummy variables within the framework of neutrosophic statistics. This model is designed for regression analysis under conditions of uncertainty, extending the classical regression model with dummy variables. We also present regression and analysis of variance under neutrosophic statistics. The application of our model is demonstrated through simulation and comparative studies, showing that the results differ from those obtained using classical regression. Our findings indicate that the degree of uncertainty significantly impacts the predicted and residual values.
Utilizing Recycled Sand from Excavation Wastes for Sustainable Cement Mortar Production
Authors: Bader Nour , Irshidat Mohammad R. , Maglad Osama
Published: July 2024

This research investigates the feasibility of using recycled sand produced from excavation waste as natural sand alternative for sustainable cement mortar production. Two different types of recycled sand, namely limestone powder (RS1) and scalping powder (RS2), were collected and characterized. Thorough characterization encompassed particle size distribution, morphology, specific gravity, water absorption, and chemical composition. The recycled sands are then utilized to replace natural sand in mortar compositions, with varying proportions reaching up to 20%. The properties of the produced mortars were examined using the following tests: compressive strength, workability, density, water absorption, and thermal stability via thermogravimetric analysis (TGA). The results revealed that the inclusion of RS in cement mortar led to a decrease in compressive strength and workability, coupled with an increase in water absorption for both types of recycled sand. The decline in strength became more pronounced with higher RS proportions, with RS1 demonstrating superior compressive strength compared to RS2. Despite these effects, the thermal stability of cement mortar was only marginally impacted by the presence of RS. This research underscored the promise of recycled sand from excavation waste in cement mortar production, highlighting performance characteristics and suggesting further investigation, especially regarding thermal behavior under elevated temperatures. Doi: 10.28991/CEJ-2024-010-06-012 Full Text: PDF
Utilizing GIS and Machine Learning for Traffic Accident Prediction in Urban Environment
Authors: Khan Atif Ali , Hussain Jawad
Published: July 2024

Traffic accident prediction is crucial to preventive measures against accidents and effective traffic management. Identifying hotspots can facilitate the selection of the most critical survey points to note the contributing features. In this research, an effort has been made to identify hotspots and predict traffic accident occurrences in an urban area. Accident data was obtained from the Rescue 1122 Emergency Services of Faisalabad, and hotspots were identified using Moran’s I in ArcGIS. Results showed that most hotspots were located around the General Transport Stand (GTS) area due to the maximum number of road users. The temporal investigations showed that the accident occurrence was significant from 1 to 2 p.m. The identified hotspots were further investigated by conducting a field survey. Essential features such as road geometric features, road furniture, and traffic data were used for developing Machine Learning Algorithms for accident prediction. Using Computer Vision, traffic data was extracted from recorded videos. Random forest, linear regression, and Decision tree algorithms were developed using Python in the Jupyter Notebook environment. The decision tree algorithm showed a maximum accuracy of 84.4%. The analysis of contributing factors revealed that road measurements had the maximum effect on accident occurrence. Doi: 10.28991/CEJ-2024-010-06-013 Full Text: PDF
Local Scour around Different-Shaped Bridge Piers
Authors: Reddy Siva K. , Kalathil Sruthi T. , Chandra Venu
Published: July 2024

Local scour around piers is the major cause of bridge failures, and its estimation is critical for safe design. The present study aims to identify a modified pier shape that can reduce local scour compared to a circular pier. In addition, M5 models are developed for maximum scour depth prediction and compared with the existing equations available in the literature. Thus, the effect of pier shape and alignment on local scour is experimentally investigated using three pier models with the same cross-sectional area placed in isolated and tandem arrangements under clear-water conditions. These are circular (M1) and two modified pier shapes (M2 and M3), where M2 is a combination of semi-circle and triangle oriented either way (M2a and M2b), and M3 is a further modification to M2a with a small protrusion on the semi-circular end. The results showed that the local scour depth for aligned (skew angle, α = 0°) M2a, M2b, and M3 piers is reduced by 23.5%, 50%, and 55%, respectively, compared to the M1 pier but not if α > 0°. In tandem arrangements, the least scour depths observed around M1 and M2a at X = 1.0D (X is clear-spacing between piers and D is pier diameter), and M3 and M1 at X = 1.75D placed as front and rear pier, respectively. It is observed that the developed M5 models are more accurate compared to the existing equations. Flow intensity (V/Vc) and αhave more influence on the scour depth prediction around tandem and isolated piers, respectively. Doi: 10.28991/CEJ-2024-010-06-019 Full Text: PDF

ESG Integration In SOEs: Transformation of Environmental Protection and Embodiment of Sustainable Business in SOEs
Authors: Diva Nur Amartha Suci  , Meliaila Aurora Jillena
Published: July 2024

Climate change carries enormous risks and threatens the lives of many people. Environmental damage not only endangers living creatures, but risks causing business losses. Therefore, there is a demand from the public and investors to publish sustainability reports. The disclosure of a sustainable report not only acts as a tool to maintain reputation, but also as a form of evaluation of business activities that have been carried out in a certain period of time. Apart from that, sustainability principles are not only used as a reporting reference, but are also used as a consideration in making business and investment decisions. As a member country of the UNFCCC, Indonesia has a target to contribute to overcoming climate change. State-Owned Enterprises, which are large state-owned business conglomerations, should integrate ESG aspects as a consideration for their business operations. As mandated by Article 33 of the Constitution of the Republic of Indonesia, SOEs have control over businesses in sectors that cover the lives of many people. Through Glasgow COP26, IFRS has published ISSB as a reference in forming sustainability reports. This is a response to the systematic misalignment of sustainability reporting that exists throughout the world. Therefore, an international standardization is needed which can be used as a reference. In this case, SOEs should adopt these international standards in connection with the absence of regulations that specifically regulate the obligation for SOEs to carry out environmental considerations. This article aimed to discuss the regulatory status quo that applies in the context of implementing ESG and how ESG will later be integrated as a form of realizing sustainable business.

Bean cultivation is vital to the global food and economy, especially in Brazil. Facing challenges from diseases that affect production, it is crucial to seek new strategies to maintain productivity and sustainability. Melaleuca alternifolia, known as the tea tree due to its medicinal properties, has little explored potential in controlling diseases in bean plants. The objective of this work was to evaluate the effectiveness of tea tree essential oil in controlling diseases in bean cultivation. In vitro tests were carried out to evaluate bacterial growth, at concentrations of (0.0%, 0.05%, 0.1%, 0.5%, 1% and 2%). And antibiogram with the bacteria Xanthomonas axonopodis pv. phaseoli, in different concentrations (0.0%, 0.05%, 0.1%, 0.5%, 1%, 2% and 3%). For the fungus Pseudocercospora griseola, sporulation tests were carried out, using direct and indirect methods, at concentrations of (0.0%, 0.05%, 0.1%, 0.5%, 1%, 2%, and 3%). Furthermore, for the fungus Colletotrichum lindemuthianum, mycelial growth tests were carried out with the same concentrations. The experiments took place in vivo, with a completely randomized statistical design, involving five replications per treatment and concentrations varying from (0.0%, 0.05%, 0.1%, 0.5%, 1% and 2%). Disease incidence was assessed using a diagrammatic scale, disease severity, Area under the Disease Progress Curve (AACPD) and Area under the Incidence Progress Curve (AACPI). Melaleuca Essential Oil (EO) inhibited the development of fungi and bacteria in in vitro tests starting at 0.5%. In vivo, Melaleuca Essential Oil (EO) showed a significant reduction in the incidence and severity of the disease from 0.5% in both fungi and bacteria. Melaleuca EO can be an effective alternative for disease control in bean cultivation.

Introduction: The aim of this study was to investigate the effects of mangosteen extract on the number of spermatogenic cells in mice exposed to cigarette smoke. Objective: Thirty mice aged 8 to 12 weeks were randomly divided into 5 groups. The negative control group (K-) received 1% CMC Na/head, the positive control group (K+) was exposed to smoke and received 1% CMC Na/head, (P1) was exposed to smoke and administered mangosteen extract 6,045 mg/head, (P2) was exposed to smoke and administered mangosteen extract 12.09 mg/head, (P3) was exposed to smoke and administered mangosteen extract 24.18 mg/head. Each group was exposed to one cigarette per day, and treatments were administered one hour after smoke exposure. All treatments and smoke exposure lasted for about 45 days. Necropsy was performed after the final day of treatment, and histopathological slides of the testes were processed and stained under a light microscope. The observed parameter was spermatogenic cell count. The data were analyzed using analysis of variance (ANOVA) based on a completely randomized design, and further analyzed using Duncan’s multiple range. Results: Cigarette smoke significantly reduced spermatogenic cells (spermatogonia, primary spermatocytes, and spermatids) (p<0.05). Administration of mangosteen peel extract significantly increased spermatogenic cells (p<0.05). The highest increase in spermatogenic cells was observed in the group given 12.09 mg/gram BW of mangosteen peel extract (P2). The increase in spermatogenic cells due to the administration of mangosteen peel extract and cigarette smoke did not reach normal conditions (K-). Conclusion: This study concludes that mangosteen peel extract (Garcinia mangostana Linn) could maintain the number of spermatogenic cells in male mice (Mus musculus) exposed to cigarette smoke (p<0.005).

Background: Heat-cured acrylic resin is a type of acrylic resin whose polymerization process is done by heating. Several methods have been used to improve the properties of acrylic resin materials, one of which is by adding natural fiber and using pineapple leaf fiber as a natural fiber to strengthen heat-cured acrylic resin in impact strength tests. Objective: To determine the impact strength of acrylic resin, with the addition of Pineapple leaf fiber and without the addition of Pineapple leaf fiber. Research Method: This research uses laboratory experimental research. The sampling method used 16 samples per group, consisting of 2 groups, namely the control group (acrylic resin without the addition of Pineapple leaf fiber) and the treatment group (acrylic resin with the addition of Pineapple leaf fiber). Test the impact strength using the Universal impact tester machine (joule). The test result data was analyzed using the independent T-test (Sig < 0.05). Results: The highest mean impact test value was in the treatment group (acrylic resin with the addition of Pineapple leaf fiber) at 4.22 Joules, while the lowest mean value was in the control group (acrylic resin without the addition of Pineapple leaf fiber) at 1.45 Joules. Based on data analysis, sig = 0.000 (< 0.05), which means there is a difference in the impact strength value of acrylic resin with the addition of Pineapple leaf fiber and without the addition of Pineapple leaf fiber. Conclusion: There is an effect of adding pineapple leaf fiber to heat-cured acrylic resin.

Background: The function of mastication, phonetic, and aesthetic of fully edentulous patient can be restored by complete denture treatment. The use of semi-adjustable articulator, suction effective impression method and neutral zone technique are important to enhanced a stable and retentive complete denture with good occlusion. Semi- adjustable articulator and suction effective method ensures the dentures constructed according to patient’s physiological movements and denture’s border seal captured according to patient’s anatomy. Neutral zone technique ensures the teeth arrangement in the space where the displacing forces of the lips tongue and cheeks are balanced. Those three approaches are expected to provide optimal prosthetic integration. Purpose: This case report aimed to describe the management of complete denture treatment in a resorbed mandibular with suction effective method and neutral zone technique using a semi-adjustable articulator. Case: A 67-year-old female patient wanted dentures because of all the mandibular teeth already extracted five months prior to the patient’s arrival. The mandibular posterior alveolar ridge showed dextral and sinistral tapering. Case Management: A complete denture with an acrylic base was fabricated with suction effective method and neutral zone technique using a semi-adjustable articulator. Conclusion: Resorbed mandibular ridge case management using a semi-adjustable articulator with suction effective method and neutral zone technique can improve complete denture retention and stability.

A Meliponicultura é a criação racional de abelhas-sem-ferrão (ASF), visando a comercialização de seus produtos e conservação do meio ambiente. O objetivo deste projeto foi realizar atividades de educação ambiental a partir do tema Meliponicultura, visando contribuir com o esclarecimento sobre desenvolvimento sustentável e preservação ambiental da Amazônia. O projeto foi realizado com 38 crianças do sexto ano de uma escola pública municipal na cidade de Coari, Amazonas, e contou com 5 etapas: 1) Exposição teórica; 2) Caminhada em uma trilha ecológica para visitar colmeias de ASF na natureza; 3) Visita a um Meliponário Didático para apresentação da organização social das abelhas; 4) Oficina lúdica sobre educação ambiental; 5) Avaliação das atividades. No encerramento da visita foi oferecido um lanche saudável para as crianças incluindo mel de ASF. Houve uma boa aceitação das atividades realizadas, em que a maioria das crianças declarou ter adorado o projeto. Houve momentos de interação e esclarecimento sobre a importância das ASF para o meio ambiente e para a preservação do ecossistema Amazônico. Quando perguntado se as crianças gostariam que houvesse mais atividades semelhantes a que foi desenvolvida na escola, 92% (n = 35) das crianças responderam que sim e 8% (n = 3) não responderam à questão. O projeto contribuiu para o esclarecimento sobre a importância da biodiversidade, da polinização e da conservação dos ecossistemas. A partir deste projeto espera-se que as crianças possam sensibiliza-se sobre a necessidade da preservação da Amazônia e se tornem agentes multiplicadores do desenvolvimento sustentável.
