ABSTRACT

Background:

Root canal therapy (RCT) and pulpotomy are two common treatment modalities for managing dental pulp infections, but their comparative effectiveness in terms of patient outcomes remains unclear. This root canal therapy (RCT) aimed to assess and compare patient outcomes between teeth treated with traditional RCT and pulpotomy

Materials and Methods:

In this single-center RCT, a total of 120 patients presenting with symptomatic dental pulp infections were randomly assigned to either the RCT group or the pulpotomy group. The RCT group received conventional root canal treatment, which involved complete removal of infected pulp and obturation of the root canals. The pulpotomy group underwent a procedure where only the coronal pulp tissue was removed, followed by the placement of a medicament. Pain levels, infection resolution, and tooth survival were assessed at 6 months and 1 year posttreatment.

Results:

At the 6-month follow-up, patients in the RCT group reported significantly lower pain scores (2.5 ± 0.8) compared with the pulpotomy group (4.3 ± 1.2, P < 0.001). Infection resolution was also higher in the RCT group (92%) compared with the pulpotomy group (78%) at 6 months. Tooth survival rates at 1 year were significantly higher in the RCT group (95%) compared with the pulpotomy group (81%, P < 0.05)

Conclusion:

This RCT demonstrates that traditional RCT is superior to pulpotomy in terms of pain reduction, infection resolution, and tooth survival. Patients who underwent RCT experienced less pain, faster infection resolution, and better tooth survival rates compared with those who received pulpotomy. These findings support the use of RCT as the preferred treatment modality for dental pulp infections.
Association of insomnia and daytime napping with metabolic syndrome and its components in a Korean population: an analysis of data from the Korean Genome and Epidemiology Study
Authors: Lee Da-Been , Yoon Dae-Wui , Baik Inkyung
Published: February 2024

OBJECTIVES: We investigated the association between metabolic syndrome (MetS) and the coexistence of insomnia and daytime napping, because limited data have been reported regarding this association.METHODS: The study population was 8,440 participants aged 40-65 years, who were from the Korean Genome and Epidemiology Study. Self-reported information on insomnia symptoms and nap duration was used to define exposure variables. Data on waist circumference (WC), blood pressure (BP), and fasting blood glucose (FBG), triglyceride (TG), and high-density lipoprotein cholesterol levels in blood were used to define MetS. Multivariate logistic regression analysis was performed to obtain odds ratio (OR) and 95% confidence interval (CI).RESULTS: In multivariate logistic regression analysis, the coexistence of insomnia and napping was not significantly associated with MetS. However, the insomnia and non-napping group showed higher ORs of high TG (OR, 1.19; 95% CI, 1.02 to 1.39) and high BP (OR, 1.28; 95% CI, 1.10 to 1.49) than the non-insomnia and non-napping group. The combination of non-insomnia and napping and that of insomnia and napping showed higher ORs of high TG (OR, 1.13; 95% CI, 1.00 to 1.29) and high FBG (OR, 1.59; 95% CI, 1.14 to 2.21), respectively. In analyses of insomnia symptoms, only the combination of difficulty in maintaining sleep (DMS) and non-napping showed a higher OR for MetS (OR, 1.25; 95% CI, 1.03 to 1.52) than the non-DMS and non-napping group.CONCLUSIONS: Individuals with insomnia, particularly those who do not take naps, were disproportionately likely to have MetS components, especially TG or BP. Information on these variables may help predict individuals’ vulnerability to specific MetS components.

Published: February 2024

Ehrlichia ruminantium is the tick-borne rickettsia causing heartwater to wild and domestic ruminants. Previously, Multilocus Sequence Typing of this pathogen (MLST) highlighted the co-circulation of two genotypic groups within nearby villages from Burkina Faso where  vaccination assays had been previously recurrently performed. In the present study the laboratory strains that had been involved in  vaccination assays, which evidenced their close relationships with strains that were later involved in local outbursts, were genotyped. Characterization of the bacterium genetic diversity was extended to four distant Beninese localities where no vaccination assays had ever  been performed, through sampling of N=500 specimens of the local tick vector, Amblyomma variegatum. This led evidencing an  even higher frequency of new multilocus MLST genotypes in Benin than in Burkina Faso, 93% of the Beninese genotypes included at least  one new private allele (i.e., no detected elsewhere), while this was only the case of 80% bacteria genotypes sampled in Burkina Faso. Investigating the genetic structure of the bacterium across the Africa continent revealed a reduction of its diversity in the eastern and  southern part of the continent relatively to West Africa. As the bacterial genetic diversity currently remains highest in West Africa than  anywhere else in the continent, this area remains optimal for the development and/or testing of vaccines against heartwater.

Published: February 2024

The aim of this study was to find an alternative to chemical control by improving sorghum's natural defense system. The effect of two  biocontrols, Vacciplant and Calliet, on phenolic compound and leaf pigment levels was evaluated. Vacciplant was prepared at  concentrations of 0.675; 0.9; 1.125; 1.35 and 1.575 mg/mL, while Calliet was prepared at concentrations of 4 ; 8 ; 12 ; 16 and 20 mg/mL.  After preparation, the biocontrol solutions were sprayed onto sorghum leaves 60 days old. Incubation times of 24, 48, 72 and 96 hours  were observed after spraying. The sorghum leaves were then harvested and freeze-dried for quantification of total phenols and leaf  pigments. Results showed that Vacciplant at a concentration of 1.125 mg/mL after 72 hours of incubation allowed to have the highest  contents of total phenols (76.63 mg/g MF), while Calliet at concentration of 4.00 mg/mL after 24 hours of incubation allowed to have the  highest contents of total phenols (67.28 mg/g MF). With regard to photosynthetic activity, the results also showed an increase in leaf  pigment content following the application of biocontrols. The use of biocontrols could therefore be an interesting alternative to chemical  control in sorghum.

Published: February 2024

Artemisia annua L. est une plante annuelle d’origine chinoise cultivée principalement pour ses vertus antipaludiques. Cependant, la  production de la biomasse est déficitaire par rapport à la demande nationale. La présente étude a été menée dans le but de déterminer  les meilleures conditions de culture d’Artemisia annua L. pour la croissance des plants de l’espèce au Burkina Faso. Ainsi, différents  traitements ont été appliqués sur les graines (ébouillantage), sur le substrat de culture (ébouillantage, ensoleillement) et le mode de  semis. Les résultats obtenus ont montré que les graines non ébouillantées semées en ligne sur substrat ébouillanté ont donné un  nombre maximum de levée des plants. Également, la biomasse et la hauteur moyenne des plantes obtenues avec le compost, le bokashi  et le NPK étaient respectivement de 22,4 g et 95±0,11 cm ; 14,4 g et 100±0,11 cm ; 16,26 g et 93±0,11 cm montrant ainsi une meilleure  production de biomasse foliaires avec le compost. Pour la transpiration, les résultats obtenus ont montré qu’en présence de compost, du  NPK ou du bokashi, les plantes transpiraient le plus (soient 0,1kg d’eau perdue en moyenne par heure). Au regard de ces résultats, le  semi de graines sur un substrat préalablement ébouillanté améliore la levée des plants et l’utilisation du compost améliore la croissance  voire la production des feuilles des plants.

 

English title: Evaluation of the ability to emerge on various substrates and effect of organomineral fertilization of Artemisia annua L plants growth in Burkina Faso

 

Artemisia annua L. is an annual plant of Chinese origin cultivated mainly for its antimalarial properties. However, biomass production is  insufficient to meet national demand. The present study was conducted to determine the best conditions for growing Artemisia annua L.  plants in Burkina Faso. Thus, different treatments were applied to the seeds (scalding), the growing medium (scalding, sunlight) and the  sowing method. The results obtained showed that non-scalded seeds sown in rows on scalded substrate gave a maximum number of  seedling emergence. Also, the average biomass and height of plants obtained with compost, bokashi and NPK as substrates were 22.4 g  and 95±0.11 cm ; 14.4 g and 100±0.11 cm ; 16.26 g and 93±0.11 cm, respectively, showing a better production of leaf biomass with  compost. For transpiration, the results obtained showed that in the presence of compost, NPK or bokashi, the plants transpired the most  (i.e. 0.1 kg of water lost on average per hour). In view of these results, semi-sowing seeds on a previously scalded substrate improves the  emergence of the plants and the use of compost improves the growth and even the production of the leaves of the plants.

Published: February 2024

Grâce à son importante composition en lipides, protéines, glucides et micronutriments, le lait de cajou dispose de potentialités nutritives  à même de le valoriser comme alternatif au lait animal. Toutefois, à l’instar de nombreux laits alternatifs, les laits d’origine végétale ne  présentent pas toujours des profils organoleptiques optimums pour leur vulgarisation auprès des consommateurs. La présente étude  visait à appréhender l’appréciation hédonique et décrire des indicateurs sensoriels de quatre formulations (F1 à F4) de boisson lactée acidifiée à base de lait d’amande de cajou et de jus d’ananas, à partir de panels de dégustateurs et des échelles de notation sensorielle à  7 points. La formulation F4 constituée de 25% de lait d’amande de cajou et 75% de jus d’ananas a enregistré le meilleur score de  préférence et était appréciée par 69,65% des panélistes dégustateurs. Cette formulation présente de plus grandes intensités de  perception de quatre indicateurs sensoriels, notamment la coloration (4,75 ±1,13/7), fluidité (4,56 ±0,63/7), le goût ananas (5 ±1,15/7) et  l’arôme ananas (5 ±1,21/7). En revanche, les formulations F1 à F3 présentent des intensités plus ou moins considérables pour d’autres descripteurs sensoriels tels que l’arôme de cajou, la sensation de craie en bouche, l’arrière-goût et le goût d’amande de cajou. Sur la  base de ses caractéristiques sensorielles supérieures, la production de la formulation F4 pourrait représenter une voie appropriée pour la  valorisation alimentaire des amandes de cajou.

 

English title: Investigation in sensory traits from beverage formulations based on cashew milk and pineapple juice

Because of its high lipid, protein, carbohydrate and micronutrient content, cashew milk has the nutritional potential to be a valuable  alternative to animal milk. However, like many alternative milks, plant-based milks do not always have the optimal organoleptic profiles  to be popularized by consumers. The aim of the present study was to assess the hedonic appreciation and describe the sensory  indicators of four formulations (F1 to F4) of acidified milk drink based on cashew almond milk and pineapple juice, using taster panels  and 7-point sensory rating scales. The F4 formulation, made up of 25% cashew almond milk and 75% pineapple juice, recorded the highest preference score, appreciated by 69.65% of panel tasters. This formulation showed higher perception intensities for four sensory  indicators, notably color (4.75 ±1.13/7), fluidity (4.56 ±0.63/7), pineapple taste (5 ±1.15/7) and pineapple aroma (5 ±1.21/7). On the other  hand, formulations F1 to F3 showed more or less considerable intensities for other sensory descriptors such as cashew aroma, chalky  mouthfeel, aftertaste and cashew kernel taste. On the basis of its superior sensory characteristics, the production of the F4 formulation    could represent a suitable route for the food valorization of cashew kernels.

The fish communities of Lake Maabo are little studied despite the increasing fishing effort on this ecosystem. The present study aims to  establish weight-length (Pt = a Lt b) and total length-standard length (LT = p + q LS) relationships, and to determine the condition factor  of the main species of Lake Maabo. To this end, morphometric data were collected monthly between January 2016 and December 2019 from artisanal fisheries. A total of 4,891 specimens belonging to 25 commercial fish species were caught using various fishing gears andtechniques. The regression coefficient b ranged from 1.17 (Hydrocynus forskali) to 4.69 in (Ctenopoma kingsleyae). Two species showed positive allometric growth, 2 with isometric growth and 21 species with negative allometric growth. The total length-standard length relationship was positive and significant for all species (r2 between 0.666 and 0.999). Only Tetraodon lineatus had a condition factor within the range recommended for mature tropical freshwater fish. The condition factor ranged from 0.536±0.182 to 3.810±0.850, with an  overall mean of 1.804±0.833. These results showed that fish in Lake Maabo are under increasing anthropogenic pressure. They show the  need to study the population dynamics of the most exploited species in that Lake.

Published: February 2024

Les extraits de plante sont des mélanges complexes de composés tels que les flavonoïdes dont l’identification nécessite des méthodes  conventionnelles souvent sophistiquées et coûteuses. Il est donc nécessaire de développer des méthodes plus simples et abordables en  termes de faible coût et de facilité de mise en œuvre pour l’identification de ces composés. Dans le présent travail, nous avons utilisé les  méthodes électrochimiques pour étudier le comportement des flavonoïdes en vue de leur identification dans l’extrait d’acétate d’éthyle  de Euphorbia hirta L par voltammétrie cyclique. Les voltamogrammes des standards de flavonoïdes ont révélé la présence de plusieurs  pics d’oxydation irréversibles attribuables à l’oxydation des différents groupements hydroxyles présents sur l’aglycone. Il ressort de cette  étude qu’il serait possible de mettre en évidence la différence entre des flavonoïdes glycosylés et non glycosylés. En effet, l’analyse  électrochimique d’un extrait d’acétate d’éthyle de Euphorbia hirta L. et de différentes fractions obtenues à partir d’une chromatographie  flash a permis de révéler la présence de la myricitrine, la quercétine, la quercitrine, le kaempférol et la lutéoline dans ces extraits. Les  résultats de l’étude ont montré que la méthode électrochimique pourrait être utilisée pour l’identification des flavonoïdes dans les  extraits de plantes.

 

English title: Electrochemical behavior of flavonoids from ethyl acetate extract of Euphorbia hirta L.

Plant extracts  are complex mixtures of compounds such as flavonoids. Identifying these compounds requires conventional methods that are often  sophisticated and expensive. It is therefore necessary to develop simples for identification of these compounds. In the present work, we  used electrochemical methods to study the behavior of flavonoids for their identification in ethyl acetate extract of Euphorbia hirta L. The voltammograms of the flavonoid standards several irreversible oxidation peaks attributable to the oxidation of the various hydroxyl  groups on the aglycone. This study shows that it would be possible to highlight the difference between glycosylated and non- glycosylated flavonoids using the electrochemical tool. Electrochemical analysis of an ethyl acetate extract of Euphorbia hirta L. and  various fractions obtained by flash chromatography revealed the presence of myricitrin, quercetin, quercitrin, kaempferol and luteolin in  these extracts. The study results showed that the electrochemical method could be used to identify flavonoids in plant extracts

L’étude ethnopharmacologique a été réalisée sur les plantes à vertus anthelminthiques utilisées dans le traitement des problèmes  gastro-intestinaux chez les aulacodes d’élevage. Cette étude avait pour objectif de répertorier ces plantes utilisées au sud et au centre  Bénin. Pour cela, des enquêtes ont été menées dans 15 communes. Au total, 55 plantes ont été recensées avec des indications sur leur  utilisation et parmi lesquelles Vernonia amygdalina (12%), Carica papaya (10,67%), Nauclea latifolia (8%), Azadirachta indica (5,33%), Eleas  guineensis (5,33%) et Adansonia digitata (4%) ont été les espèces les plus citées. Les feuilles et les fruits étaient les plus sollicitées  dans l’alimentation des aulacodes. Les modes d’utilisation et d’administration diffèraient d’un aulacodiculteur à un autre. Les familles les  plus représentées étaient les Asteraceae (10,90%), Mimosaceae (9,09%), Euphorbiaceae (7,27%), Cesalpiniacea (5,45%), Rutaceae  (5,45%), Bombacaceae (3,63%), Cucurbitaceae (3,63%), Meliaceae (3,63%), Papilionaceae (3,63%), Rubiaceae, (3,63%) et Vitaceae (3,63%).  Les aulacodiculteurs utilisaient plus les feuilles (40%) et les fruits (37%) que la plante entière (8%), la tige (6%), les racines (5%) et les  écorces (4%). Leurs propriétés antiparasitaires étaient induites par des composés chimiques qui devront être identifiés ultérieurement à  travers les recherches phytochimiques.

English title: Ethnopharmacological study of medicinal plants used in the traditional treatment of gastro-digestive parasitoses of farmed  grasscutter in some departments of Benin

The ethnopharmacological study was carried out on plants with anthelmintic properties used in the treatment of gastrointestinal  problems in farmed grasscutter. This study aimed to list these plants used in southern and central Benin. For this, surveys were carried  out in 13 municipalities. In total, 55 plants were identified with indications on their use and including Vernonia amygdalina (12%), Carica  papaya (10.67%), Nauclea latifolia (8%), Azadirachta indica (5.33%), Eleas guineensis (5.33%) and Adansonia digitata (4%) were the most cited species. The leaves and fruits were the most used in the grasscutter diet. Methods of use and administration differed from one  grasscutter farmer to another. The most represented families were Asteraceae (10.90%), Mimosaceae (9.09%), Euphorbiaceae (7.27%), Leg- Caes (5.45%), Rutaceae (5.45%), Bombacaceae (3.63%), Cucurbitaceae (3.63%), Meliaceae (3.63%), Papilionaceae (3.63%), Rubiaceae, (3.63%) and  Vitaceae (3.63%). Grasscutters used the leaves (40%) and fruits (37%) more than the whole plant (8%), the stem (6%), the roots (5%) and  the bark (4%). Their antiparasitic properties were induced by chemical compounds which will have to be identified later through  phytochemical research.
The mismatch between geographical indication protection against evocation and its underlying objectives
Authors: Song Xinzhe , Zhou Ying
Published: February 2024

The deliberations on the revision of the European Union (EU) system for geographical indications (GIs), proposed in 2022, manifest the contentious nature of protecting GIs against evocation. This article shifts attention to the origins of the anti-evocation protection, allowing for further exploration of how the protection deviates from the objectives behind its establishment. The study shows that the flaws that triggered the prospective reform were foreseen in the 1990s when anti-evocation protection was first introduced in GI law. In the 1990s, legislative discussions surrounding the introduction had already brought to light a lack of clarity regarding the objectives, the over-inclusiveness of the evocation test, and the potential absurdities it might generate. Those once potential flaws have gradually become a reality, and practice has manifested a mismatch between the anti-evocation protection and its underlying purposes. The judicial and legislative authorities’ latest bridging efforts have missed the fundamental solution to the mismatch. The EU GI legislative reform should give due consideration to adopting a harm-based approach, thus bringing the anti-evocation protection closer to its core objective of preventing harm.
Spatial and Temporal Analysis of Carbon Dioxide Concentrations over Italy by means of OCO‑2 Satellite Data Series
Authors: Romaniello Vito , Spinetti Claudia , Piscini Alessandro
Published: February 2024

Carbon dioxide is a greenhouse gas with sink and source related to natural cycles and anthropic activities. OCO‑2 is a NASA carbon dioxide dedicated mission launched in 2014 aimed to measure the CO2 concentrations in the atmosphere by recording sunlight reflected off the Earth and provides, at the state of the art, the highest spatial resolution for mapping CO2 at global scale. In this work, for the first time, we statistically analyse 8 years of OCO‑2 acquisitions over Italian territory, obtaining the main trend and the seasonal behaviour of CO2 over land. After data reprocessing and compensating on temporal frequency of OCO‑2 acquisitions over Italy, a mean of 21 ppm of increment in the period from 2015 to 2022 has been found. In the data time series, we also noticed a significant acceleration in the trend between 2019 and 2020 and a return to average values of the trend after the COVID19 pandemic lockdown. In addition, such trends have been compared with those achieved by the European Centre for Medium Range Weather Forecasts (ECMWF) model. The data time series was also used to perform a spatial analysis of areas characterized by lower/higherc CO2 concentrations to detect sinks/sources in Italy due to the land use. The analysis reveals that the North Italian regions, with more population and industries, are the source of CO2; moreover, the fundamental role of vegetation as a sink of CO2 is confirmed.
Influence of Audit Committee Independence on the Quality of Audit Reports of Sacco’s in Homabay County, Kenya
Authors: Limonya Joel Okinyu
Published: February 2024

Every operating organization keeps tabs on its development by producing accurate financial statements at the conclusion of each fiscal year, which are subsequently distributed to various individual users who are concerned with the organization's development. The accuracy of the financial accounts is then verified by an audit procedure, which is sealed by a transparent audit report provided to the specific business by the audit committee. The main objective of this study was to examine the influence of audit committee independence on the quality of audit reports of Sacco’s in Homabay County, Kenya. This was supported by the fact that there are numerous Sacco’s in Homabay County, many of which had apparently experienced audit problems in the past. Stakeholders’ theory served as the study's compass. This study adopted a descriptive causal research design, the target population was 104 audit committee members of deposit taking Sacco’s in Homabay County as at December 2021. Out of the target population determined using the Krejcie and Morgan formula, 82 members of the audit committee provided responses for the study. Primary data was collected using research questionnaire which involved drop and pick method. Descriptive statistics including a frequency table, mean, and standard deviation were used for data analysis while inferential statistics included Pearson’s correlation analysis. The study found that audit committee independence in Homabay County, Kenya, had a positive and significant impact on the caliber of audit reports on Sacco’s (r=0.530, p<0.05). The study recommends that Sacco’s audit committee members should be as independent as possible in executing their mandate so as to ensure audit reports provided are of quality.

Published: February 2024

An optimal investment portfolio needs to be formed before an investor invests because it can help investors determine which financial instruments are suitable to choose in order to get the maximum return or profit and the minimum level of risk. In the current situation, where there is an economic transition to a smart carbon economy or low carbon economy, it is necessary to form the optimal portfolio of stocks to facilitate investors in making investments. The purpose of this study is to form the optimal investment portfolio using the Black-Litterman model in a smart carbon economy. The data used is stock data from 24 companies listed on the LQ45 Low Carbon Leaders index for the period 2022-2023. Based on the research results, the Black-Litterman model generates the optimal portfolio with a 0.1% expected return. Thus, the optimal portfolio results with the Black-Litterman model are estimated to generate a profit of 0.1% for smart carbon stock data listed on the LQ45 Low Carbon Leaders index for the 2022-2023 period.

Published: February 2024

The optimal portfolio is a portfolio chosen by investors from the many options available in the collection of efficient portfolios. To get the optimal proportion, which is the maximum return and minimum risk, it is necessary to analyze the stocks to be selected in the investment model. The research objective is to determine the optimal return, risk, and proportion for each banking stock portfolio in Indonesia in the period February - July 2023. The method used is the Single Index Model. The process of determining the optimal proportion of stocks with the Single Index Model requires stock and market return data as the main basis for applying this method. This study involves the formation of an optimal portfolio of daily closing prices of 46 banking stocks.  As a result of this research, there are 5 optimal stocks that meet the criteria for optimal portfolio formation with each fund proportion of 21.43% (BNII), 13.52% (BDMN), 35.02% (BBRI), 23.69% (BTPN), and 6.34% (BBCA).  Expected return from optimal stocks is 0.152% and the risk that will be borne by investors is 0.0011% per day.

Coffee is one of the popular drinks for Indonesian people. Coffee consumption in Indonesia has increased very rapidly. The influence of lifestyle and the increasing number of cafes and coffee shops contribute to the increase in coffee consumers. One downstream processing of coffee beans is roasting coffee beans, which consists of light, medium, and dark roasting. This study aimed to determine the antioxidant activity of Gununghalu Arabica Coffee (Coffea arabica L.) with Light Roasting, Medium Roasting, and Dark Roasting Techniques. This research is an experimental study, where the antioxidant activity analysis was carried out using the DPPH method (2,2-diphenyl-1-picrylhydrazyl). Gununghalu Arabica coffee with light, medium, and dark roasting techniques positively containing flavonoids, alkaloids, saponins, tannins, and terpenoids. The results showed that the IC50 value of Gununghalu Arabica coffee for light, medium, and dark roasting was 102.94 ppm, 70.66 ppm, and 87.66 ppm. The test results show that the antioxidant activity of Gununghalu Arabica coffee with light roasting techniques are moderate, while medium and dark roasting techniques are strong. The results of this study are expected to provide implications for the development of coffee processing techniques to have maximum health benefits.

Published: February 2024

of Bandung, as a group that faces unique challenges related to adapting to new environments and lifestyles, often experience problems related to the quality of their sleep. Urban environmental factors such as noise, bright light, and air pollution can affect their sleep patterns. This study uses a longitudinal observational approach to investigate the influence of sleep quality on the health and academic achievement of migrant students. Data were collected via questionnaires and, where possible, sleep measuring devices. The analysis results show a significant correlation between sleep quality, physical health, mental health, and academic achievement. College students with better sleep patterns tend to have better physical health, lower stress levels, and higher academic achievement. The implication of this research is the importance of supporting the sleep quality of overseas students through educational programs and accessibility to mental health resources. Lifestyle factors such as a balanced diet, adequate physical activity, and stress management are also important in improving sleep quality. This research provides in-depth insight into the factors that influence the sleep quality of migrant students and provides a basis for the development of interventions that support their well-being and academic success in urban environments.

Authors: Pirdaus Dede Irman , Ibrahim Riza Andrian , Yuningsih Siti Hadiaty
Published: February 2024

Adolescents in Tasikalaya District show a tendency to be susceptible to Tramadol protection, a type of opioid analgesic commonly used to reduce moderate to severe pain. This phenomenon is a resource for the medical community, health practitioners, local governments and other related parties. Serious attention is needed to this problem to prevent negative impacts on the health and welfare of adolescents in the region. Coordinative efforts between the health, education and government sectors need to be strengthened to develop effective prevention and intervention strategies. A deep understanding of the factors driving Tramadol is key in designing appropriate preventive measures. This research examines the use of the drug tramadol among teenagers in Tasikalaya Regency using a qualitative approach and Differential Association Theory. The results of the study showed that adolescents' support for tramadol was caused by social and environmental factors, including interactions with peers and family members who also used the drug. Teenagers often rationalize their behavior and have certain attitudes that influence their decision to take tramadol. Apart from that, the easy availability of tramadol medication and affordable prices also influences teenagers' choices. This study provides a deeper understanding of the problem of tramadol among adolescents and suggests comprehensive preventive measures.

Detrital Chromian Spinel Geochemistry from Miocene Red Bed Sandstones of Northeastern Iraq: Implication for Provenance and Tectonic Setting
Authors: Aziz Nabaz
Published: February 2024

The provenance and tectonic setting of clastic sediments present in the Miocene Red Bed Series located in northeastern Iraq were analyzed. The analysis is based on the composition of detrital chrome spinel and represents the first examination of this topic. The detrital chrome spinel exhibits Cr # (Cr/(Cr + Al)) values ranging from 0.54 to 0.77 and Mg # (Mg/(Mg + Fe2+)) values ranging from 0.37 to 0.69. This indicates a potential incorporation of ultramafic sources, possibly including peridotites (namely Harzburgite and Lherzolite precursors), within the supra-subduction zone. The analysis of modified Cr-spinels extracted from the Red Beds indicates that the source rocks underwent a process of metamorphism and that the Cr-spinel particles were surrounded by a magnetite rim. The Cr-spinel compositions of the examined samples are situated tectonically in the fore-arc setting of peridotite protoliths, except for a small number of samples that exhibit boninite affinity. The observed resemblance in the Cr-spinel number content between the examined specimens and the Zagros Ophiolite peridotites suggests that the Red Beds may have originated from the Cretaceous Mawat Ophiolite Complex. The deposition of Paleocene Walash-Naopurdan rocks indicates that the lower allochthon served as a source during this process. The tectonic context of the Red Bed Series suggests that the allochthonous terranes in the Mawat region were transported and obducted onto the northeastern Arabian passive margin in the early Miocene period. The deposition of the Red Bed Series occurred concurrently with the closure of the Neo-Tethys Ocean in the Miocene.

Permeability derived from magnetic resonance advanced logging tools was used to unlock the Pliocene sandstone reservoir heterogeneity. Permeability prediction from well logs is a significant target due to the unavailability of core data. The hydraulic flow unit approach is used to classify the reservoir rocks according to their porosity-permeability relationship. The predicted permeability is calculated using Sapphire-Dh magnetic resonance porosity and permeability relationship for each flow unit. Flow Zone Indicator and the quality flow unit have a direct proportion relationship. For the model's verification, the predicted permeability is plotted against the measured resonance permeability in Sapphire-Dh as a reference studied well, showing highly matching results. Accordingly, the applied approach is implemented in the other three wells, which have neither core samples nor advanced logs measurements.

Short animated film inspired by the surrounding environment in North Kalimantan which often uses boats called outboard motorboats or ketinting boats as a means of river transportation. Ketinting is a type of traditional boat that uses a motor propeller and is placed at the back in a position immersed in the water as a driving force to run the boat using diesel fuel, and is often found in various areas, especially the North Kalimantan region. Ketinting boats are usually used as a means of transportation to move places via river routes, and are usually also used by fishermen as transportation to find income in the form of fish. This animation tells the story of the life of a computer student who has parents who work as fishermen. This animation tells the problem of how difficult and expensive it is to get diesel fuel and then the students find a solution by using technology that uses solar energy as a substitute for diesel fuel. The animation creation process consists of pre-production, production and post-production using dialogue and music as support. The results of the animated video are created as a medium for entertainment, information and education related to solar energy that can be watched by all groups.
