La consommation du manioc, sous forme des pâtes alimentaires (Foufou ou chikwangue) nécessite de passer par le rouissage qui réduit la toxicité due à la présence de l’acide cyanhydrique. Cependant, les caractéristiques des exploitations et les techniques de rouissages sont  variées. Ainsi l’objectif de cette étude était de réaliser une typologie des exploitations agricoles familiales de la commune de Maluku, en rapport avec les techniques de rouissage du manioc. Une enquête portant sur 344 exploitations agricoles a permis de collecter les données y afférentes. Les caractéristiques sociodémographiques, les caractéristiques de l’exploitation, les contraintes auxquelles font face les exploitations  ainsi que la localisation (villages) ont été prises en compte. La typologie a été réalisée sur base de l’Analyse en Composantes Multiples (ACM) et la Classification Hiérarchique Ascendante (CHA). Les résultats révèlent 3 types d’exploitations agricoles. Le premier axe principal est dominé par le village, le type de contraintes, la productivité en cosette, le type de la main-d’œuvre et le type de matériel végétal.  Le second axe principal est dominé par  les techniques de rouissage.

 

The objective of this study is to develop a typology of cassava-producing farms in the Maluku area, on the outskirts of Kinshasa in the Democratic Republic of Congo. The criteria chosen are: socio-economic characteristics (type of workforce, membership of a group of producers and type of production constraints); characteristics related to cassava production technology (exploited area, plowing equipment and type of plant material); the characteristics linked to the cassava processing technology (retting method, retting duration and chip yield) and the village. The data was collected by survey on 344 farms operating in 6 villages. The typology was made thanks to an ACM and finalized by a CAH. The results of the study made it possible to group cassava producers into three types on the basis of the variables retained. The results reveal 3 types of farms. With the village, the type of constraints, the productivity in cosette, the type of labor and the type of plant material as the dominant characteristics of the first axis of the typology and the mode and duration of retting as the dominant characteristics of the second axis.

Landslide Soil Failure Parameters Characterization Using Geoelectrical Resistivity Methods in Uruagu, Nnewi, Anambra State, Nigeria
Authors: Uwaezuoke Charles Chinedu , Airen Osariere John
Published: May 2023

Electrical Resistivity Imaging (ERI) and Vertical Electrical Sounding (VES) were deployed over the Uruagu landslide area. The main purpose of the study was to characterize the landslide failure parameters in to identify the soil failure mechanisms. Ten profiles of 2D ERI measuring 200 m each, and thirty VES, with three VES along each profile, were executed. Nine of the ten profiles were executed within the landslide site while one profile was executed in a residential street as a control profile. Four soil samples were also taken for physical and geotechnical laboratory index analysis. The PASI resistivity meter was used for the geoelectrical resistivity measurements. The Wenner-Schlumberger array was deployed for the ERI with a minimum electrode spacing of 10 m. The Schlumberger array was deployed for the VES  with a maximum current spacing of 130 m. ERI resistivity data analysis involved inversion using the RES2DINV software package involving mean model residual and construction of iso-apparent resistivity contour maps. VES resistivity data analysis involved calculated parameters from plotted field data on a log-log graph then used as initial models in an iterative forward modeling WinResist software package. The results of the ERI and VES for the control profile reveal that the subsurface strata are originally composed of silty clay of resistivity values (16.7 – 60.9) Ωm, clayey silty sand having resistivity values (116 – 800) Ωm and sandstone layer with resistivity values (>814 Ωm). The ERI and VES results for the devastated landslide site reveal counteraction material of resistivity values (>814 Ωm), colluvia and regoliths (116 - 300 Ωm), and variably wet weathered sandstones of resistivity values (<60.9 Ωm). The laboratory results revealed the landslide site is majorly composed of silty sandy clay, silty clay, sandy silty clay, and sandstones as the pre-landslide existing lithologies. The natural water content ranges from 10.6% to 14.0%. The liquid limit ranges from 44.0% to 46.0%, the plastic limit ranges from 15.0% to 17.0%, and the plasticity index from 28.0% to 29.1%. The geophysical and laboratory results revealed consistency in the lithological units in agreement with the characteristic geology of the study area. The landslide site has high gully slope gradients and collects a large volume of floods during the intense rainy season. These soils, during the intense rainfall, imbibe more water, following their high plasticity slide along the sandstone to activate the soil failure.

Published: May 2023

Dans le but de contribuer de façon durable à la sécurité alimentaire des ménages, cinq (05) grandes familles de pratiques agro-écologiques (Gestion Intégrée de l’Agriculture et de l’Elevage (GIAE), Gestion Intégrée de la Fertilité des Sols (GIFS), Agro-Foresterie (AF), Conservation des Eaux et du Sol (CES), Agriculture de Conservation (AC)) ont été introduites, depuis les années 90, dans les zones cotonnières au Bénin. Trente ans après leur introduction, il importe d’identifier les grandes familles de pratiques agro-écologiques réellement adoptées par les producteurs. Ainsi, à travers un questionnaire semi-structuré, les données ont été collectées auprès de 300 producteurs de coton choisis au hasard et répartis dans trois communes (Banikoara, Sinendé et Djidja) représentatives des trois zones cotonnières (haut nord, centre-nord et sud) du Bénin. Une Analyse Factorielle des Correspondantes (AFC) a été réalisée avec le logiciel R i386 4.0.4. Les résultats de l’AFC montrent que, sur les cinq (05) grandes familles de pratiques agro-écologiques introduites dans les zones cotonnières au Bénin, trois (03) grandes familles ((GIFS), (GIAE) et (AF)) ont été fortement adoptées. Par contre, les pratiques de la grande famille du CES ont été marginalement adoptées et celles de l’AC n’ont pas du tout été adoptées dans ces zones.

 

In order to contribute in a sustainable way to household food security, five (05) major families of agro-ecological practices (Integrated Management of Agriculture and Livestock (GIAE), Integrated Management of Soil Fertility (GIFS), Agro-Forestry (AF), Water and Soil Conservation (CES), Conservation Agriculture (CA)) have been introduced since the 1990s in the cotton-growing areas of Benin. Thirty years after their introduction, it is important to identify the main families of agro-ecological practices actually adopted by producers. Thus, through a semi-structured questionnaire, data were collected from 300 cotton producers chosen at random and distributed in three communes (Banikoara, Sinendé and Djidja) representative of the three cotton-growing areas (upper north, center-north and south ) from Benin. A Corresponding Factor Analysis (FCA) was performed with R i386 4.0.4 software. The results of the AFC show that, out of the five (05) large families of agro-ecological practices introduced in cotton-growing areas in Benin, three (03) large families ((GIFS), (GIAE) and (AF)) have been strongly adopted. On the other hand, the practices of the large SWH family have been marginally adopted and those of CA have not been adopted at all in these areas.

Embebição de sementes de Alcantarea imperialis (Carrière) Harms em tratamentos pré-germinativos de temperatura sob duas condições de luminosidade
Authors: Freitas Gustavo Viana de , Moura Regina Braga de
Published: May 2023

In this study we aimed to investigate the action of light and pre-germinative temperature treatments on the imbibition of Alcantarea imperialis seeds. The seeds were arranged in experimental units of 25 seeds without previous disinfestation treatment, subjected to high and low temperatures, and the absence and presence of light. The results revealed the germination of A. imperialis seeds only in the presence of light, showing differences in water absorption between temperature treatments over time and confirming the triphasic imbibition behavior. Despite the differences found between treatments, germination was low, suggesting that the process may have been influenced by seed viability and purely physical water processes. According to this, the importance of disinfestation procedures and vigor tests are emphasized, as well as the need for future studies on the water relations of seeds of this species.

ANOMALY DETECTION IN ZIGBEE-BASED IOT USING SECURE AND EFFICIENT DATA COLLECTION
Authors: Sadikin Fal , Wiranda Nuruddin
Published: May 2023

This article outlines various techniques for detecting types of attacks that may arise in ZigBee-based IoT system. The researchers introduced a hybrid Intrusion Detection System (IDS), combining rule-based intrusion detection and machine learning-based anomaly detection. Rule-based attack detection techniques are used to provide an accurate detection method for known attacks. However, determining accurate detection rules requires significant human effort that is susceptible to error. If it is done incorrectly, it can result in false alarms. Therefore, to alleviate this potential problem, the system is being upgraded by combining it (hybrid) with machine learning-based anomaly detection. This article expounds the researchers’ IDS implementation covering a wide variety of detection techniques to detect both known attacks and potential new types of attacks in ZigBee-based IoT system. Furthermore, a safe and efficient meth-od for large-scale IDS data collection is introduced to provide a trusted reporting mechanism that can operate on the stringent IoT resource requirements appropriate to today's IoT systems.

The research work was carried out to analyse the breeding practices followed by the goat farmers in southern districts of Tamil Nadu. Majority of the goat farmers used own farm bred male animals (38.88 per cent) for breeding purpose followed by purchased the bucks from other goat farmer’s herd (25.66 per cent). They maintained the sex ratio of male to female goats as 1:20 (37.22 per cent), 1: 25-30 (42.78 per cent), 1: 1 above 30 (20 per cent) in the study area. Chi-square revealed that there was a highly significant (P< 0.01) association was observed between sex ratio of goats in the farmers herds among districts. The age at first mating in Kanniadu, Kodi adu and non-descript breeds of goats were 10.00 ± 0.23, 10.07 ± 0.16 and 10.18 ± 0.09 months, respectively and kidding interval for the above three breeds were 7.50 ± 0.16, 7.35 ± 0.16 and 7.44 ± 0.06 months, respectively. The kidding and twinning per cent was significantly (P< 0.05) higher in non-descript goats. Triplets and quadruplets were significantly (P< 0.01) higher in Kanniadu. Lifetime use for breeding purpose was significantly higher for Kodi adu goats.Production and supply of superior male germplasm from the research institutes and organized livestock farms is helpful to maintain the breed characteristics of native goats.
Black Tea Extract Prevents iAs Induced Transformation of HaCaT Cells via Modulation of Cellular Damage, Inflammation and TGF-β Signalling Cascade
Authors: Ghosh Archismaan , Roy Madhumita
Published: May 2023

Chronic exposure to inorganic arsenic (iAs) leads to development of cancer of various organs, most prevalent being skin cancer. iAs induces its carcinogenic potential by excess generation of free radicals, which induces DNA, protein, lipid damage; supresses activity of antioxidant enzymes; enhances prolonged inflammatory conditions and modulates TGF-β signalling cascade, all of which promote carcinogenesis. Black tea extract (BTE), a popular beverage and an established antioxidant, has been used in present study to combat the ill effects of iAs exposure. Present study has been conducted on normal human skin keratinocytes, HaCaT cells. Estimation of Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) generation was done using 2’,7’-dichlorodihydrofluorescein diacetate (DCFH-DA) and Greiss reagent. Damage to DNA (by Micronuclei and Comet assay), protein (by protein carbonyl assay kit) and lipid (by lipid peroxidation) were assessed. Activity of antioxidant enzymes, inflammatory cytokines, p50 and p65 subunits of NF-κB were assessed using respective kits. Immunoblotting assay was performed to assess expression of TGF-β and modulation of its downstream signalling molecules. Results indicate that BTE quenches iAs induced free radicals; inhibits DNA, protein and lipid damage; prevents deactivation of antioxidant enzymes; suppresses inflammation and prevents EMT inducing modulation of TGF-β pathway, thus thwarting iAs induced carcinogenesis in HaCaT cells.

Authors: Martins Wagner Lemos
Published: May 2023

Esse estudo apresenta parte de uma investigação realizada durante o Programa de Mestrado em Geografia da Universidade Federal do Tocantins, Campus de Porto Nacional. A pesquisa trata de uma análise ambiental de Veredas, localizadas no córrego Correntinho, que se encontra inserido no munícipio de Miracema do Tocantins-TO, e teve como objetivo analisar as condições ambientais em que se encontram as Veredas localizadas no curso principal do córrego em questão. Nesse sentido, adotou-se como metodologia a aplicação do Índice de Vegetação por Diferença Normalizada (NDVI), e o Índice de Água por Diferença Normalizada (NDWI). O uso da ferramenta NDVI indicou que a massa de vegetação no curso do córrego Correntinho apresenta-se em vários estágios. Assim, os resultados possibilitam uma compreensão da fitofisionomia das Veredas, permitindo até mesmo teorizar quanto à evolução de estratos na comparação entre dados de diferentes períodos, configurando um importante instrumento de monitoramento ambiental das ações que possam trazer agravos ambientais. Dessa forma, a análise de dados do NDVI e NDWI apresentou-se com grande potencial para o estudo dos ambientes de veredas, além de permitir a teorização quanto a uma compreensão da fitofisionomia das Veredas, que merecem atenção por sua importância para o bioma Cerrado. Nesse sentido, essas geotecnologias são apropriadas para a análise  ambiental das Veredas, ao permitir a comparação entre dados de diferentes períodos, e  no acompanhamento de ações que possam causar impactos ambientais.

FEATURES OF HISTORICAL REALITIES CONCEPTUALIZATION (based on the English-language scientific historical literature)
Authors:   Astrakhan State Technical University, Bocharnikova E.A.
Published: May 2023

Dealing with the problem of scientific knowledge representation, the article dwells on some features of the historical reality conceptualization related to the implementation of scientific fields interaction phenomenon in the process of knowledge formation of a specific scientific discipline, in this case, history. Historical discourse is a set of knowledge, opinions, views and assessments of historical events, facts that occurred in certain periods, under certain social, economic and political conditions. As an example, we considered the text fragment from the English-language scientific historical book. The analysis was carried out from the standpoint of contextual, semantic, definitional and conceptual approaches. It is established that in the process of describing the historical concept “war forecast”, the author’s conceptual system interacts with military, technical, socio-economic, psychological, geographical types of discourses. At the end of the article, it is concluded that interdiscursive interaction makes it possible to identify new characteristics, better present the idea of the described concept, identify other phenomena and concepts associated with it and trace the author’s assessment. In general, applying the cognitive linguistics research approaches to the analysis of integrated knowledge, one can receive a more accurate and complete understanding of a certain concept content in an effort to obtain true knowledge.

Dari hasil pengujian tersebut, maka dapat disimpulkan bahwa media pembelajaran berbasis video materi sistem transmisi continuously variable transmission (CVT) pada mata kuliah sepeda motor dan motor kecil “Sangat Layak” digunakan untuk kegiatan pembelajaran.

 

After the introduction of online learning during the pandemic that has been going on for almost two years, face-to-face learning has undergone several changes in the teaching and learning process. The concentration of learning media is still unable to display native movements in practice and is less interactive. These weaknesses will be resolved if adjustments and media development are made. In previous research on video-based learning media, there were still some shortcomings in terms of audio, visual, and the order of learning materials. This study aims to develop and determine the feasibility of video-based learning media for continuously variable transmission (CVT) transmission system materials in motorcycle and small motorcycle courses according to material experts, media experts, and student trials. The research method uses Research and Development (R&D) with the ADDIE development model. The results of the video-based learning media feasibility test received a percentage of 89.41% from material expert validators, 88% from media expert validators, and 92% from student trial results. From the results of these tests, it can be concluded that video-based learning media material for continuously variable transmission (CVT) transmission systems in the motorcycle and small motorcycle course "Very Feasible" is used for learning activities.

MAGNETIC FIELD-DEPENDENT ELECTRIC CURRENT ON A PERIODIC POLY(DA)-POLY(DT) DNA MOLECULE STRUCTURE
Authors: Yudiarsah Efta
Published: May 2023

An electric current flowing on the Poly(dA)-poly(dT) DNA molecule structure has been calculated. The current was calculated from transmission probabilities by employing Landauer-Buttiker formalism. Green’s function technique has been used for obtaining the transmission probabilities. The DNA molecule structure was modeled within the tight-binding Hamiltonian model approach. The model takes into account electron hopping parameters which are dependent on the magnetic field as well as the electric field. The presence of a magnetic field causes the Peierls phase factor on the electron hopping parameters. The calculation results at low electric voltages show that after decreasing, the electric current oscillates with the magnetic field. However, at higher electric voltages, the electric current is increasing and oscillates with the magnetic field.

Maternal colonization by Streptococcus agalactiae or Group B Streptococcus(GBS) during pregnancy increases the risk of neonatal infection due to vertical transmission from mother to fetus before or during labor. The study aimed to evaluate the antimicrobial activity of the SP80 fraction (obtained from Allium sativum) and its synergism associated with the antibiotic against strains of GBS. The broth microdilution was used to determine the antimicrobial activity of the SP80 and to establish the MIC of SP80 (2.40 mg/mL). By using, the disk diffusion method, fifty-five clinical isolates and 1 ATCC of GBS were tested against the association of the SP80 fraction with antibiotic PEN and AMP, respectively, for synergistic assessment. The results showed that the association of SP80 + PEN did not alter the response of PEN alone. In contrast, the association of SP80 + AMP caused the mean inhibition halos to increase with a p<0.001. The SP80 fraction has antimicrobial activity against GBS, and the association with the antibiotic AMP showed a synergistic effect, which did not occur when in association with PEN.

The design of conventional architectural landscapes often has issues with inadequate direct visual effects and inadequate levels of resident satisfaction, but the design of green architectural landscapes typically does not have these issues. Creating room for landscaping is likewise an impractical endeavor. Because of this, the authors of this study suggest a number of different Path-finding algorithms for green building landscape space and environmental optimization design. A variety of path-finding algorithms may be used to maximize the multi-objective scale of the architectural landscape. The expense of the construction as well as public utilities such as the space environment are included among the optimization's goals and objectives. The findings indicate that the many pathfinding solutions that were presented are able to optimize the architectural landscape setting, and the occupants' level of happiness has increased as a consequence.

The consumption of bovine milk and its derivatives is associated with inflammation, gastrointestinal disorders and the development of diseases in humans. Most studies related to milk effects are based on either clinal trials or experimental models such as mice and cell cultures. In this study we present the nematode Caenorhabditis elegans as an alternative model to evaluate the effects of milk on oxidative stress in other animal models. The toxicological effect of 20% milk exposure for 8h on C. elegans was evaluated by progeny quantification, body size and pharyngeal pumping rate. Treating the worms with milk did not affect the worms brood size but interfered with their fecundity by delaying the average number of eggs in the first day of oviposition when compared to the control group. The size of worms treated with milk were significantly smaller compared to control. The pharyngeal pumping rate of milk-treated animals was not significantly different compared to untreated animals. Taking together, the results suggest that 20% milk treatment is not toxic for the worms but induces a minor delay achieving its adulthood and therefore its reproduction period. Exposure milk did not reduce the worms’ survival under stress conditions and increase endogenous ROS levels. This study contributes to characterize the effects of milk exposure on the C. elegans nematode.

Objective We assessed the incidence of frailty and identified the independent risk factors for the occurrence of frailty in elderly patients with obstructive sleep apnea syndrome (OSAS), which aims to provide a reference for the clinical treatment of OSAS and frailty.Methods We selected 1006 elderly patients with OSAS diagnosed using polysomnographic (PSG) between January 2015 and October 2017. We divided the patients into the non-frailty group (n = 731) and the frailty group (n = 275) based on the FRAIL scale score, compared the difference between the two groups. Multivariate cox regression analysis was used to identify the factors affecting the onset of frailty among elderly patients with OSAS.Results༚ 275 patients experienced frailty, yielding an incidence of 27.34%. Multivariate cox regression analysis showed that age(HR = 1.058, 95% CI:1.043–1.074, P < 0.001), constipation(HR = 1.490, 95%CI: 1.101–2.018, P = 0.010), carotid atherosclerosis (CA)(HR = 1.739, 95% CI: 1.299–2.330, P < 0.001), and renal insufficiency (RI)(HR = 1.878, 95% CI: 1.177–2.996, P = 0.008) are independent risk factors for frailty in elderly patients with OSAS. And platelet count(PLTC)(HR = 0.998, 95% CI: 0.996-1.000, P = 0.040), the mean arterial oxygen saturation(MSaO2)(HR = 0.950, 95% CI: 0.918–0.984, P = 0.005) are protect factors.Conclusion The incidence of frailty among elderly patients with OSAS is relatively high, and it was significantly higher in patients with severe OSAS than in those with mild or moderate OSAS. Age, constipation, CA, and RI are independent risk factors, whereas mean oxygen saturation and platelet count are protective factors for frailty in elderly patients with OSAS.

Background The review aims to determine the risk predictability of S. mutans in the development of carious lesions in children with primary dentition.Methods Longitudinal observational studies with at least 6 months follow-up and evaluating S. mutans presence in caries-free children less than 6 years of age for the development of any cavitated or non-cavitated carious lesion. Six databases and grey literature were searched without any restrictions. Risk of bias was evaluated using New Castle Ottawa scale for longitudinal studies and the certainty of evidence was evaluated by Grading of Recommendations Assessment, Development and Evaluation using GRADEpro software. Meta- analysis was performed using a random effect (DerSimonian and Laird, DL) model and heterogeneity was evaluated using tau-squared, I² statistics and prediction interval. Sensitivity analysis was performed to assess the relationship between the S. mutans presence at baseline and the caries development, according to the sample and methods used for the microbiological assessment and the length of follow-up of the studies. Publication bias was checked by funnel plot using a random effect (DerSimonian and Laird, DL) model.Results Twelve studies met the inclusion criteria and were included in the review. Four studies received a maximum of 9 stars and among the remaining eight studies, six received 8 stars and the rest two studies were assigned 7 stars in the risk of bias scale. After pooling the results quantitatively, odds ratio (OR) was found to be 4.13 (95% CI: 3.33, 5.12), suggesting that children with S. mutans had 4 times higher odds of developing caries later (p < 0.001). Four studies were pooled to compare future caries experience among children with and without S. mutans at baseline, obtaining standardized mean difference (SMD) of 0.85 (95% CI: 0.33, 1.37), indicating large effect (p < 0.001). Certainty of evidence was found to be high, and no publication bias was reported by the funnel plot criteria of symmetry.Conclusions Presence of S. mutans in a preschool child is a risk predictor for future caries experience. Early identification of children with increased caries-risk may facilitate in implementation of appropriate preventive strategies.

Earthen architecture has a rich history of providing durable and sustainable shelter for humans. However, many of these heritage sites are now facing abandonment and obsolescence. Kasr Khanguet Sidi Nadji in the Algerian Sahara is not exempt from this reality. To address this critical situation, we propose a sustainable, eco-friendly, and cost-effective solution for the restoration of the Ksar that takes into account the needs of its residents and its heritage value. Our approach utilizes the anastylosis method which implies that we reuse original on-site components as building materials whenever possible. We introduce new materials only when necessary after subjecting them to rigorous testing and control. Additionally, we take into account the complex challenges of human, natural, and technical factors involved in the restoration process, offering a practical solution to restore and preserve the earthen heritage of the Ksar while benefiting its residents.
