Authors: Ginting Siti Aisah , Dewi Nora Ronita
Published: February 2023

This research aims to identify interactional patterns in the ESP online teaching mode of the fifth semester of the English Department at Universitas Negeri Medan. This research applies descriptive quantitative methodology and focuses on class A of the English Department's fifth semester, which consisted of 36 students and one lecturer who taught online utilizing Google Meet as the platform. This study's data consisted of three audiovisual recordings made by the lecturer. The data were recognized using the IRF pattern of interaction identification table and analyzed using the IRF model. The first discovery revealed that the most frequently used pattern by the lecturer is IRF as a full pattern, followed by IR as a semi-complete pattern and IF as an incomplete pattern. The second finding revealed that elicitation occurs more frequently in classroom interactions. It is possible to infer that this classroom had a high level of interaction since the lecturer provided equal opportunities for students to begin the conversation, resulting in active student participation.
Sustaining the Terrestrial Biosphere in the Anthropocene
Authors: Kleidon Axel
Published: February 2023

Many aspects of anthropogenic global change, such as shifts in land cover, the loss of biodiversity, and the intensification of agricultural production, threaten the natural biosphere. The implications of these specific aspects of environmental change are not immediately obvious; therefore, it is hard to obtain a bigger picture of what these changes imply and distinguish the beneficial from the detrimental, where human impact is concerned. In this paper, I describe a holistic approach that allows us to obtain such a bigger picture and use it to understand how the terrestrial biosphere can be sustained in the presence of increased human activity. This approach places particular emphasis on the free energy generated by photosynthesis—energy that is required to sustain both the dissipative metabolic activity of ecosystems and human activities (with the generation rate being restricted by the physical constraints of the environment). Thus, one can then identify two types of human influence on the biosphere and their resulting consequences: the detrimental effects caused by enhanced human consumption of this free energy and the beneficial effects that allow for more photosynthetic activity and, therefore, more dissipative activity within the biosphere...

Objetivo: O objetivo deste trabalho foi avaliar o comportamento da madeira da espécie Eucalyptus urophylla × Eucalyptus grandis estocada ao ar livre durante o período de sete meses, para a determinação de seus ganhos e perdas energéticas. Foram utilizadas árvores com cerca de 13 anos, transformadas em toretes de um metro, uma parte para ser estocada ao ar livre por sete meses, outra para análise da madeira recém-coletada. Para ambas as análises os toretes foram transformados em discos depois em cavacos, uma parte utilizada na determinação das densidades da madeira e produção do carvão vegetal, outra parte transformada em partículas para as análises químicas. As propriedades físicas da madeira apresentaram perdas durante o tempo de estocagem, enquanto o teor de lignina (20,99 a 24,02 %) e solubilidade em (NaOH) (13,53 a 21,42 %) aumentaram. Nas propriedades energéticas tanto da madeira como do carvão vegetal, as madeiras estocadas por sete meses apresentaram baixa densidade energética (2095,49 e 968,36 kcal/m-3, respectivamente) altos teores de materiais voláteis (84,71 e 61,45 %, respectivamente) e altos valores de carbono fixo (15,1 e 80,92 %, respectivamente) e poder calorífico. O tempo de estocagem afetou de forma negativa nas propriedades físicas da madeira, principalmente sua densidade, onde acabou impactando na densidade energética tanto da madeira quando do carvão vegetal, reduzindo assim a quantidade de energia por unidade de massa, entretanto apresentaram bons resultados de carbono fixo e poder caloríficos, demostrando o seu potencial na geração de energia.

Authors: ÖNCÜ ÖNER Tülay , TEMEL Melih , PAMAY Seda , ABACI Altin Kardelen , KAYA AKKALE Hilal Betül
Published: February 2023

Grapevine (Vitis vinifera L.) is one of the oldest and most important perennial crops worldwide which has been the subject of extensive genetic studies including gene mapping, genetic transformation, and DNA fingerprinting. Grapevines are rich in polysaccharides, polyphenolic compounds, and various secondary metabolites, many of which have significant importance in food, agrochemical, and pharmaceutical industries. While metabolites are one of the indicators of quality of grapevines, the presence of them makes grapevine one of the most difficult plants to extract DNA from. These metabolites not only affect DNA extraction procedures but also downstream reactions such as restriction digestion and PCR. Development of new genotyping techniques based on sequencing such as genotyping by sequencing (GBS) requires high-quality DNA for digestion and sequencing. To date, several protocols have been developed for DNA extraction from grapevine. In this study, three different protocols with modifications were compared for DNA extraction performance from grapevine leaves from four different cultivars. Efficiencies of these methods were determined by extracted DNA’s quantity and quality. To confirm the suitability for GBS, extracted DNA was digested with restriction enzymes. Although all protocols were based on the traditional CTAB method, they resulted in different DNA yield and restriction digestion efficiency. The modified protocol including PVP-40 and ß-mercaptoethanol was found to be the most efficient method to obtain high quality and quantity grapevine DNA that is amenable to restriction digestion.

The Indonesian Dakon Game: A Learning Method to Link Spiritual Values to Economic Praxis
Authors: Chandra Robby Igusti , Boiliu Noh Ibrahim , Widjaja Budiman
Published: February 2023

Few spiritual, philosophical, and theological concepts concerning the economy have emerged especially since the Middle Age. One of them centred on the Trinitarian God concept. The concept proposes mutuality, relationship, and unity based on love and grace as shared spiritual values. The question that arises is how to educate people in applying it. This study explores whether the Dakon game, a traditional game mainly used in Java, Indonesia can be used as a learning method to apply that theological concept and their spiritual values to economic concepts and practices. The study method is literature research. The finding shows that the Dakon game causes the players to acquire a tacit knowledge that includes skills, values, and spirituality obtained through the practices of distributing wealth, sensitivity to others, and unity combined with achieving economic objectives. Although various challenges in the Indonesian context need further study, the finding can contribute to the praxis of applying spiritual values to economic praxis in Indonesia. Keywords: Trinitarian God Concept, spirituality, peace, economy, tacit knowledge, education.

MEMORIA Y DESILUSIÓN ANTE EL POSTRUJILLISMO EN TRES NOVELAS DOMINICANAS
Authors: Victoriano-Martínez Ramón A.
Published: February 2023

En este artículo analizaré la representación de varios momentos sociopolíticos dominicanos vistos a través de tres novelas escritas por mujeres. Desde el final de la dictadura de Trujillo (1930-1961) la República Dominicana vivió un período de gran turbulencia política: dos golpes de estado, una guerra civil, una invasión estadounidense y un gobierno marcadamente autoritario que dirigió una guerra sucia contras las fuerzas de izquierda. Al mismo tiempo la sociedad dominicana emprendió un camino de crecimiento económico sostenido y consolidación de una clase media que se insertó plenamente en los circuitos capitalistas de consumo.

Margarita Cordero en
Nosotras las de entonces
(2020) y Rita Indiana en
La estrategia de Chocueca
(2000) y
Hecho en Saturno
(2018) retratan las reacciones a tres épocas decisivas en el devenir histórico de República Dominicana y sus efectos y consecuencias: 1) la Revolución de abril de 1965 y los llamados “Doce años” (1966-1978), 2) el advenimiento de la democracia y la década perdida de 1980 y 3) el retorno de Balaguer y la instauración de las políticas neoliberales, respectivamente.

Si tal y como señala Idelber Avelar en
The Untimely Present:
“The imperative to mourn is the postdictatorial imperative par excellence”. (3) estas tres novelas no solamente lamentan la caída y pérdida del proyecto liberal dominicano sino que, desde una perspectiva femenina, ofrecen una descarnada radiografía de sus respectivos presentes.
High-resolution Study of Planetesimal Formation by Gravitational Collapse of Pebble Clouds
Authors: Polak Brooke , Klahr Hubert
Published: February 2023

Planetary embryos are built through the collisional growth of 10–100 km-sized objects called planetesimals, a formerly large population of objects, of which asteroids, comets, and Kuiper Belt objects represent the leftovers from planet formation in our solar system. Here, we follow the paradigm that turbulence created overdense pebble clouds, which then collapse under their own self-gravity. We use the multiphysics code GIZMO to model the pebble cloud density as a continuum, with a polytropic equation of state to account for collisional interactions and capturing the phase transition to a quasi-incompressible “solid” object, i.e., a planetesimal in hydrostatic equilibrium. Thus, we study cloud collapse effectively at the resolution of the forming planetesimals, allowing us to derive an initial mass function for planetesimals in relation to the total pebble mass of the collapsing cloud. The redistribution of angular momentum in the collapsing pebble cloud is the main mechanism leading to multiple fragmentation. The angular momentum of the pebble cloud and thus the centrifugal radius increases with distance to the Sun, but the solid size of the forming planetesimals is constant. Therefore we find that with increasing distance to the Sun, the number of forming planetesimals per pebble cloud increases. For all distances, the formation of binaries occurs within higher hierarchical systems. The size distribution is top-heavy and can be described with a Gaussian distribution of planetesimal mass. For the asteroid belt, we can infer a most likely size of 125 km, all stemming from pebble clouds of equivalent size 152 km.
Delay-weighted Calibration: Precision Calibration for 21 cm Cosmology with Resilience to Sky Model Error
Authors: Byrne Ruby
Published: February 2023

One of the principal challenges of 21 cm cosmology experiments is overcoming calibration error. Established calibration approaches in the field require an exquisitely accurate sky model, and low-level sky model errors introduce calibration errors that corrupt the cosmological signal. We present a novel calibration approach called delay-weighted calibration, or DWCal, which enables precise calibration even in the presence of sky model error. Sky model error does not affect all power spectrum modes equally, and DWCal fits calibration solutions preferentially from error-free modes. We apply this technique to simulated data, showing that it substantially reduces calibration error in the presence of realistic levels of sky model error and can improve 21 cm power spectrum sensitivity by approximately 2 orders of magnitude.
Distribution and Evolution of the Li Abundance in Red Clump Stars Can Be Explained by Internal Gravity Waves
Authors: Li Xue-Feng , Shi Jian-Rong , Li Yan , Yan Hong-Liang , Zhang Jing-Hua
Published: February 2023

The study of Li phenomena in red clump (RC) stars can give us a deeper understanding of the structure and evolution of stars. Chanamé et al. explained the RC Li abundance distributions naturally using only standard post-main-sequence (MS) Li evolution models when the distribution of progenitor masses and the depletion of Li during the MS observed in MS stars were considered, thus neither an extra Li depletion nor Li creation mechanism is required. Nevertheless, it is interesting to consider the effects of mixing caused by some extra mechanisms. By constructing different models, we find that the mixing caused by internal gravity waves can explain the observed Li abundances of RC stars with low-mass progenitors. To explain this, we rely on the extra mixing induced by internal gravity waves that are excited at the bottom of the convective envelope during the red giant branch (RGB) stage. During the RGB stage, introducing internal gravity waves can improve the diffusion coefficient and strengthen the mixing effect. The effective enrichment of Li occurs during the late RGB stage and requires the diffusion coefficient of the H-burning shell to reach ∼108 cm2 s−1. Our models predict that the Li abundance decreases from ∼1.5 to ∼0.0 dex at the end of the core He-burning stage, thereby revealing ∼99% of the observed Li abundance distribution. Thermohaline mixing regulates the Li abundance of RGB stars, which combined with internal gravity waves can explain the Li abundances of most giants.

We present deep UV imaging observations of the Great Observatories Origins Survey Northern (GOODS-N) field with AstroSat/UVIT (AstroSat UV Deep Field north—AUDFn), using one far-UV (FUV) (F154W, 34.0 ks) and two near-UV (NUV) filters (N242W, 19.2 ks; N245M, 15.5 ks). The nature of the UV sky background was explored across the UVIT field, and a global mean and rms were estimated for each filter. We reach 3σ detection limits of m
AB ∼ 27.35, 27.28, and 27.02 mag for a point source in the F154W, N242W, and N245M bands respectively. The 50% completeness limits of the FUV and NUV images are m
AB = 26.40 and 27.05 mag respectively. We constructed point-spread functions for each band and estimated their FWHM, which were found to be almost the same: 1.″18 in F154W, 1.″11 in N242W, and 1.″24 in N245M. We used SExtractor to separately identify sources in the FUV and NUV filters and produce the UV source catalog of the entire AUDFn field. The source count slope estimated in FUV and NUV is 0.57 dex mag−1 (between 19 and 25 mag) and 0.44 dex mag−1 (between 18 and 25 mag), respectively. The catalog contains 6839 and 16,171 sources (brighter than the 50% completeness limit) in the FUV and NUV, respectively. Our FUV and NUV flux measurements of the identified sources complement existing multiband data in the GOODS-N field, and enable us to probe rest-frame FUV properties of galaxies at redshift z < 1 and search for candidate Lyman continuum leakers at redshift z > 0.97.
Analyzing LDEX's Current Measurements in Lunar Orbit
Authors: Bernardoni Edwin , Horányi Mihály , Szalay Jamey R.
Published: February 2023

The Lunar Dust Experiment (LDEX) on board the Lunar Atmosphere and Dust Environment Explorer mission orbited the Moon from 2014 September to 2015 April and observed a dynamic, permanently present dust cloud produced by continual meteoroid bombardment. In addition to measuring individual ejecta with radii >0.3 μm, LDEX also recorded an integrated current of the collective signal generated by the impacts of smaller ejecta particles. From this signal, we explore the potential for electrostatic dust lofting via twilight craters through correlation with changes in lunar topography. As the integrated current can contain numerous background contributions, we start by isolating regions of transient enhancements of this signal. A consistent lunar dayside enhancement is identified, with solar wind ions reflected as energetic neutral atoms shown to be a feasible source. We do not detect any enhanced integrated current correlated with the antihelion meteoroid bombardment or discernible enhancement due to electrostatic lofting via twilight craters, suggesting that electrostatic dust lofting does not contribute to the lunar dust environment at high altitudes (≫1 km).

Published: February 2023

BACKGROUND: Psychosocial problems, including anxiety or depression, potentially activate several mechanisms that affect coronary artery disease (CAD) cardiovascular risk factors. Their clinical association, however, remains undiscovered.
AIM: The objective of this study was to discover the association between the prevalence of anxiety or depression and risk factors of CAD.
METHODS: A cross-sectional study was conducted from July to October 2019. Subject population was CAD patients hospitalized in the Cardiac Care Unit at Hasan Sadikin General Hospital Bandung. We included patients with a history of CAD who underwent revascularization and filled the Hospital Anxiety and Depression Scale (HADS) questionnaire before discharge. Patients were classified according to normal (HADS score of 0–7) or abnormal levels of anxiety or depression (HADS score of 8–21). From each patient, we obtained information on risk factors of CAD, including smoking, physical inactivity, dyslipidemia, hypertension, diabetes mellitus (DM), and family history of CAD.
RESULTS: Ninety-nine CAD patients (79% male, mean age: 59 ± 10.5 years) were included in the study; 40% were smokers, 60% had physical inactivity, 11% had dyslipidemia, 57% had hypertension, 13% had DM, 7% had a family history of CAD, and 23% subjects had abnormal levels of anxiety or depression. The relationship between anxiety or depression in CAD patients and smoking behavior (p = 0.802), family history of CAD (p = 0.563), dyslipidemia (p = 0.738), hypertension (p = 0.283), and DM (p = 0.403) was not statistically significant.
CONCLUSIONS: The present study showed that the prevalence of anxiety or depression in CAD patients was relatively moderate. We revealed that psychosocial factors are not associated with risk factors of CAD, stressing that psychosocial factors are independent of conventional CAD risk factors in CAD and merit attention for individual management.
Osteolysis in Systemic Sclerosis: A Scoping Review
Authors: Guerra Miguel Gomes , Rodrigues Mariana , Águeda Ana , Rodrigues Joana , Marona José , Violante António , Oliveira Margarida
Published: February 2023

Objective

To perform a scoping review focusing on osteolysis in systemic sclerosis (SSc).

Methods

This review was performed in line with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) recommendations.

Results

From a total of 351 results, 29 articles were included for the final analysis. The publications included proved to be heterogeneous regarding the population and inclusion criteria. The lack of a standardized method of detection of osteolysis further enhanced these inequalities. Most studies reported location/prevalence of osteolysis and associations with other manifestations, with only a minority focusing on topics like predictors of osteolysis and its prognostic value. None of the authors addressed treatment approach. The most frequently analyzed and prevalent location was acro-osteolysis (AO). Diffuse cutaneous subtype and anti-topoisomerase I antibody correlated positively with AO. Disease duration, calcinosis, and digital ischemia were the features more frequently associated with AO, but only the last 2 predicted AO. Ultrasound showed high sensitivity for detection of AO.

Conclusion

Despite the effect that osteolysis has on patients with SSc, there is a significant lack of studies on this area. Notably, there are no studies that we know of focused on treatment. Also, there is a lack of longitudinal studies that would allow a reliable assessment of its prognostic value and predictors.

Published: February 2023

Objective

To estimate the incidence of herpes zoster (HZ) in patients with rheumatoid arthritis (RA) compared with the general population in the USA.

Methods

This retrospective, longitudinal cohort study used data from an administrative claims database containing both commercial and Medicare Advantage Part D data, with a data period from October 2015 to February 2020. Patients were aged ≥ 18 years and divided into 2 cohorts: patients with RA and patients without RA. Diagnosis and procedure codes were used to identify HZ cases and calculate incidence rates (IRs) of HZ in the 2 cohorts. Data were stratified by age group (ie, 18-49, 18-29, 30-39, 40-49, 50-64, and ≥ 65 yrs) and RA therapy type. IR ratios (IRRs), adjusted by cohort baseline characteristics, were estimated using generalized linear models to compare the incidence of HZ between cohorts.

Results

The overall IR of HZ was higher in the RA cohort (21.5 per 1000 person-years [PY]; N = 67,650) than in the non-RA cohort (7.6 per 1000 PY; N = 11,401,743). The highest IRs in both cohorts were observed in the age group of ≥ 65 yrs (23.4 and 11.4 per 1000 PY in the RA cohort and non-RA cohort, respectively). The overall adjusted IRR of HZ was 1.93 (95% CI 1.87-1.99,P< 0.001) for the RA cohort compared with the non-RA cohort. In the RA cohort, the highest IRs by medication class were observed in patients using corticosteroids and those using Janus kinase inhibitors.

Conclusion

These results highlight the increased incidence of HZ in patients with RA.
Prédestination et fraternité. Une lecture de Calvin
Authors: Antier Guilhen
Published: February 2023

La doctrine calvinienne de la prédestination est mise en rapport avec la problématique de la fraternité. Chez le réformateur, la prédestination fonde aussi bien l’élection des uns que la réprobation des autres dans le « conseil secret » de Dieu qui échappe au savoir théologique. Illustration de la séparation entre élus et réprouvés, les figures bibliques de Jacob et Ésaü deviennent dès lors le paradigme d’une fraternité impossible. Pourtant, le savoir de l’élection demeurant le propre de Dieu seul, un principe ecclésiologique d’indétermination voit le jour, ouvrant cette fois sur une fraternité possible dans l’horizon humain : n’importe qui peut être le frère. Ces réflexions théologiques sont reprises sous un angle anthropologique au moyen des notions lacaniennes de sujet supposé savoir et de Nom-du-Père. La fraternité s’origine-t-elle dans le savoir ou dans le non-savoir de Dieu ?
Clustering property for quantum Markov chains on the comb graph
Authors: Souissi Abdessatar , Soueidy El Gheteb , Rhaima Mohamed
Published: February 2023

Quantum Markov chains (QMCs) on graphs and trees were investigated in connection with many important models arising from quantum statistical mechanics and quantum information. These quantum states generate many important properties such as quantum phase transition and clustering properties. In the present paper, we propose a construction of QMCs associated with an $ XX $-Ising model over the comb graph $ \mathbb N\rhd_0 \mathbb Z $. Mainly, we prove that the QMC associated with the disordered phase, enjoys a clustering property.
A proof of a conjecture on matching-path connected size Ramsey number
Authors: Zhang Yixin , Zhang Yanbo , Zhi Hexuan
Published: February 2023

For two graphs $ G_1 $ and $ G_2 $, the connected size Ramsey number $ {\hat{r}}_c(G_1, G_2) $ is the smallest number of edges of a connected graph $ G $ such that if each edge of $ G $ is colored red or blue, then $ G $ contains either a red copy of $ G_1 $ or a blue copy of $ G_2 $. Let $ nK_2 $ be a matching with $ n $ edges and $ P_4 $ a path with four vertices. Rahadjeng, Baskoro, and Assiyatun [Procedia Comput. Sci. 74 (2015), 32-37] conjectured that $ \hat{r}_{c}(nK_2, P_4) = 3n-1 $ if $ n $ is even, and $ \hat{r}_{c}(nK_2, P_4) = 3n $ otherwise. We verify the conjecture in this short paper.

Published: February 2023

Background

Cardiothoracic surgery patients have an increased risk for aspiration and may require enteral access for nutrition.

Local Problem

In a cardiothoracic intensive care unit, feeding start times were delayed because of scheduling conflicts with support services. An electromagnetic device (Cortrak 2 Enteral Access System, Avanos Medical) was introduced to allow advanced practice providers (nurse practitioners and physician assistants) to independently establish postpyloric access and reduce dependence on ancillary services.

Methods

A quality improvement study was performed. Pre- and postimplementation data included order time, service arrival, tube placement time, tube positioning, and feeding start times for 207 placements. Pre- and postimplementation surveys were conducted to evaluate advanced practice provider satisfaction with enteral tube placement practices.

Results

Feeding start time for initial placement decreased by 35.5% (15.6 hours to 10 hours); for subsequent placement, by 55.2% (15.5 hours to 7.0 hours). Assistance by support services decreased by 80.4% (before implementation, 100 of 100 placements [100%]; after implementation, 21 of 107 placements [19.6%]; P < .001; ϕ = 0.815). Overall, advanced practice provider satisfaction increased. Most participants said that using the electromagnetic device was faster, nutrition was delivered sooner, and implementation was a valuable practice change.

Conclusions

Using an electromagnetic device decreased feeding start times, reduced the need for support services, and increased advanced practice provider satisfaction with small-bowel feeding tube placement practices.

Published: February 2023

Many electric vertical take-off and landing (eVTOL) aircraft intended for the urban air mobility (UAM) market are currently being designed with multirotor configurations using variable speed fixed-pitch, rigid rotors for lift. These types of rotors, which are similar in construction
to general aviation airplane propellers, are simpler than helicopter rotors and have no moving parts in the rotating frame. This paper discusses wind-tunnel testing of a full-scale, UAM multirotor size, fixed-pitch, rigid rotor with a focus on vibratory blade loads and on the ability to predict
these loads with comprehensive analysis. Test results show that vibratory loads are very high, with peak-to-peak magnitudes up to three times greater than the steady component. Correlation of test data to comprehensive analysis using geometrically exact composite beam structural elements and
dynamic inflow wake modeling captures the trends in the steady and vibratory loads though it underpredicts the magnitudes; an expected result with the level of wake modeling fidelity used. The paper also discusses the physical sources of the observed vibratory loads and suggests potential
options for mitigating their magnitude.
Efficacy of rh-PDGF-BB and Emdogain With or Without DFDBA Using M-MIST in the Treatment of Intrabony Defects
Authors: Priyanka M , Reddy K , Pradeep K
Published: February 2023

Background:

The versatile combination of emdogain or enamel matrix derivative (EMD), recombinant human platelet-derived growth factor-BB (rhPDGF-BB), and demineralized freeze-dried bone allograft (DFDBA) has not been utilized in the treatment of intrabony defects yet.

Aim:

The present study attempted to investigate the efficacy of a combination of simple, uncomplicated nature of modified minimally invasive surgical technique (M-MIST) with EMD, rhPDGF-BB, and DFDBA in the surgical management of intrabony defects and to assess the possible favorable effects for a period of 6 months.

Patients and Methods:

Thirty healthy subjects were included in the present double-blind, randomized controlled, two-arm parallel study. The test group was treated with M-MIST by using rhPDGF-BB, EMD, and DFDBA, and the control group was treated with M-MIST by using rhPDGF-BB and EMD.

Results:

Differences between the mean values of primary clinical parameters including relative attachment level, probing depth, and gingival recession at baseline and those at 6 months after surgery were statistically significant in both groups. Inter-group comparison for clinical attachment level gain, probing depth reduction, and change in the position of gingival margin revealed no statistically significant differences. Inter-group comparison revealed significant differences in linear bone growth (LBG) and percentage bone fill (% BF) but no significant differences in the residual defect depth and change in the alveolar crest position.

Conclusion:

The additional use of DFDBA provides superior benefits in terms of LBG and % BF in intrabony defects. This improvement might be attributed to the use of an osteoinductive scaffold.

Fruits are products of high economic value with a very important nutritional contribution due to their richness in vitamins, minerals, fibers and bioactive compounds. However, their consumption remains insufficient because of high post-harvest losses. This is why this study was conducted with the aim of reducing post-harvest losses of bananas. Fruit treatment consisted of soaking in Triton X-100 for 10 min, then in calcium chloride solutions at different concentrations for 30 min. The effects of treatments on shelf life and ripening parameters (ripening rate and index, firmness, pH, titratable acidity, pigment and ascorbic acid contents, and activity of chlorophyllase and pectin-methylesterase) were determined. The results show that the longest storage times (25 to 27 days) were recorded in bananas treated with Triton X-100 at 2 or 4% CaCl2. The 6 % and 8% CaCl2 treatments as well as the control bananas showed the lowest storage time. The low index and slow ripening kinetics were found in bananas treated with 2 and 4% calcium chloride. The chlorophyll content gradually decreased during the storage and this in a similar way for all the treatments. No significant variation in carotenoid content was observed over time. Firmness and pH decreased significantly, while titratable acidity and ascorbic acid content increased over time. The activity of chlorophyllase and that of pectin-methylesterase increased over time. From all the above, it appears that the combined treatments with Triton X-100 and 2 or 4% calcium chloride solution significantly extended the green life duration of the bananas and slowed the physiological processes associated to ripening.

Cardiometabolic diseases are among the main leading causes of morbidity and mortality over the world. The coexistence of a bundle of metabolic risk factors in an individual has prompted Reaven to consider it as a syndrome, called “X syndrome”. The term has later evolved and the health condition is today called “cardiometabolics syndrome” (CMS). Significant progress in the understanding of the pathophysiology of the CMS has been made during the past years. Being able to adequately assess cardiometabolic risk (CMR) is crucial for proper diagnosis, prevention, and better management of CMS, as this could be helpful to slow down its progression and complications. This could also be useful in the preclinical and clinical evaluation of potential treatment strategies. Several methods have been developed to assess the risk of developing cardiometabolic diseases in chronic and clinical setting. However, these methods show limitations when applying to short and experimental settings involving rodents. Therefore, this commentary aims at redefining and highlighting the main risk factors to be reconsidered in cardiometabolic syndrome definition; and proposing a comprehensive estimation method for the evaluation of the CMR in rodents. This is relevant for an appropriate utilization of the term CMS and a deep evaluation of therapeutic targets in experimental settings.

Published: February 2023

This paper focuses on the design of a Decision Support System for Course Material production and inventory management in the National Open  University of Nigeria. The proposed system has a model base management subsystem which is a component that differentiates Decision Support  Systems from other types of Information Systems. The model base consists of a wide collection of models which include inventory models, production  quantity models and a forecast model. Other components of the system including the data management subsystem, dialog generation and management  subsystem and the users of the system were also discussed. A prototype of the Decision Support System was developed using python  programming and MYSQL database server. Testing and validation was done using sample data of students’ enrolment and user defined inputs for the  forecast, inventory and production modules of the system. The results of the tests show high level of accuracy when compared with those obtained from  manual computations. The design is simple, flexible and can be easily modified to suit the needs of other institutions with multi-item inventory problems.

Medicinal plants have worldwide applications in the treatment of different types of human diseases. Among the medicinal plants of Ethiopia, Ocimum lamiifolium Hochst. Ex Benth (Damakese, in Amharic) is one of the well celebrated and most widely used home remedy for the treatment of a disease locally known as “Mitch” which is characterized by headache, fever, inflammation, joint pain, sweat, loss of appetite, etc. The aim of the present study on this medicinal plant was to determine the levels of heavy and trace metals in the leaves using the flame atomic absorption spectrometer (FAAS), which is nov AA model. The sampling technique used to carry out the analysis was purposive for the community in the selected area use the plant widely to treat different diseases. In addition, for each of three kebeles, selected from Duguna Fango District, three sites were selected to homogenize the samples. The concentrations or levels of heavy and trace metals, Cd, Co, Pb, Cr, Cu and Zn, in the leaves of the selected medicinal plant were  found to be (in mg/L) 0.0489, 0.0579, 0.0936, 0.153, 0.214 and 0.847, respectively. The results revealed that the selected medicinal plant accumulated these metals at different concentration levels in different sites. The results also confirmed that the concentration levels of the metals in the leaves of the selected medicinal plant were not higher than the internationally accepted permissible limits. Thus, the results indicated thatthe medicinal plant under the study is safe for medicinal uses. Furthermore, monitoring such medicinal plants for heavy and trace metals concentrations is of great importance in protecting the community from the adverse effects of the heavy metals.
Approches Africaines Sur Les Questions De Dieu, De La Mort Et Du Mal: Quelques Leçons Anthropologiques Vers Une Philosophie Interculturelle De La Religion
Authors: Mosima Pius
Published: February 2023

Dans cet article, je plaide en faveur d'une philosophie interculturelle de la religion dans une perspective africaine. Je me concentre sur les fondements  philosophiques des diverses pratiques et croyances religieuses significatives qui donnent lieu aux concepts de Dieu, de la mort et du problème du mal.  Une étude philosophique des religions traditionnelles africaines, basée sur des découvertes anthropologiques à travers les orientations culturelles  africaines, nous donne un bon point de départ pour comprendre les visions du monde et les expériences religieuses africaines. Elle révèle également que  les diverses religions du monde peuvent toutes être considérées comme offrant des perspectives différentes sur la même réalité. Plus précisément,  je soutiens que les conceptions africaines traditionnelles de Dieu, de la mort et du problème du mal pourraient apporter des contributions significatives  aux discours mondiaux sur la philosophie de la religion. Premièrement, j'articule les points de convergence et de divergence entre les religions  traditionnelles africaines et les preuves de l'existence de Dieu apportées par Saint Aquin; deuxièmement, je m'interroge sur le phénomène de la mort et  le sens de la vie. Et troisièmement, j'aborde le problème du mal et tente de trouver une solution africaine au dilemme épicurien.
