Effect of immigration in a predator-prey system: Stability, bifurcation and chaos
Authors: Kangalgil Figen , Isșık Seval
Published: June 2022

In the present manuscript, a discrete-time predator-prey system with prey immigration is considered. The existence of the possible fixed points of the system and topological classification of coexistence fixed point are analyzed. Moreover, the existence and the direction for both Neimark-Sacker bifurcation and flip bifurcation are investigated by applying bifurcation theory. In order to control chaos due to the emergence of the Neimark-Sacker bifurcation, an OGY feedback control strategy is implemented. Furthermore, some numerical simulations, including bifurcation diagrams, phase portraits and maximum Lyapunov exponents of the system, are given to support the accuracy of the analytical finding. The computation of the maximum Lyapunov exponents confirms the presence of chaotic behavior in the system.
Bearing fault diagnosis based on wavelet sparse convolutional network and acoustic emission compression signals
Authors: Tai Jinyi , Liu Chang , Wu Xing , Yang Jianwei
Published: June 2022

A bearing is an important and easily damaged component of mechanical equipment. For early fault diagnosis of ball bearings, acoustic emission signals are more sensitive and less affected by mechanical background noise. To cope with the large amount of data brought by the high sampling frequency and high sampling points of acoustic emission signals, a compressed sensing processing framework is introduced to research data compression and feature extraction, and a wavelet sparse convolutional network is proposed for resolved diagnosis and evaluation. The main research objective of this paper is to maximize the compression rate of the signal under the constraint of ensuring the reconstruction error of the acoustic emission signal, which can reduce the data volume of the acoustic emission signal and reduce the pressure of data analysis for subsequent fault diagnosis. At the same time, a wide convolution kernel based on a continuous wavelet is introduced when designing the neural network, and the energy information of different frequency bands of the signal is extracted by the wavelet convolution kernel to characterize the fault characteristics of the equipment. The energy pooling layer is designed to enhance the deep mining ability of compressed features, and the regularized loss function is introduced to improve the diagnostic accuracy and robustness through feature sparseness. The experimental results show that the method can effectively extract the fault characteristics of the bearing acoustic emission signal, improve the analysis efficiency and accurately classify the bearing faults.
La charge des images : les représentations des porteurs de l’expédition coloniale au Tendaguru (1909-1913) et leur circulation
Authors: Vennen Mareike
Published: June 2022

De 1909 à 1913, des porteurs ont déplacé 225 tonnes de fossiles dans le cadre de fouilles paléontologiques menées par le Museum für Naturkunde de Berlin dans la région colonisée du Tendaguru (sud de l’actuelle Tanzanie). Leur rôle décisif a jusqu’ici pourtant été ignoré. Le présent article analyse le contenu (soit le travail à l’image) ainsi que les conditions de production, d’utilisation et de circulation (soit le travail de l’image) de photographies représentant les porteurs au travail produites lors de cette expédition. Source importante pour une perspective logistique sur l’histoire coloniale allemande, ces photographies témoignent de la culture matérielle scientifique en contexte colonial aussi bien que des transferts et de l’accumulation d’objets dans les collections européennes. En parallèle à la circulation des fossiles, l’autrice reconstruit la circulation de ces images du transport, qui ont fait des porteurs les protagonistes anonymes d’une success-story scientifique, nationale et coloniale, participant du travail d’autoreprésentation des membres de l’expédition et contribuant à légitimer et à populariser celle-ci.
Nommer la puissance
Authors: Gonzalez Philippe
Published: June 2022

Les Pouvoirs du sacré est l’occasion pour Hans Joas de revenir sur le caractère dynamogène de la religion mis en évidence par William James et Émile Durkheim, afin de proposer une réflexion sur le processus de sacralisation de valeurs. La présente contribution noue un dialogue, inscrit dans le pragmatisme, avec les propositions joassiennes, en prenant appui sur des enquêtes réalisées en contexte évangélique. Il s’agira de montrer comment certaines pratiques spirituelles encouragées à l’horizon de célébrations collectives participent de la création de valeurs configurées par des entrepreneurs religieux soucieux de capter l’énergie religieuse des fidèles au profit de mobilisations politiques d’orientation conservatrice. Ces cas empiriques jettent un éclairage inédit sur la notion de sacré proposée par Joas, et permettent au passage d’identifier certains nœuds méthodologiques, notamment dans le rapport entre les concepts joassiens et les notions au travers desquelles les acteurs sociaux confèrent du sens à leurs expériences individuelles ou collectives.

Detection of multidrug resistance and associated genes among Salmonella species from enteric fever cases
Authors: Elumalai S. , Muthu G. , Selvam E. M. , Thiagarajan S. , Seetharaman S.
Published: June 2022

Background: Salmonella spp. has rapidly gained resistance to ampicillin, chloramphenicol, co-trimoxazole, and tetracycline (ACCoT) which necessitated the use of fluoroquinolones and cephalosporins. However, there are reports on emergence of fluoroquinolone-resistant Salmonella isolates in various parts of Asia and low resistance to third-generation cephalosporins. The incidence of multi-drug resistant (MDR) Salmonella enterica serovar Typhi (S. Typhi) in India increased in the 1990s. After a decade, studies showed reduced MDR percentage. Hence this study was performed to detect antibiotic resistance patterns and associated genes among clinical isolates of Salmonella.
Methods: A total of 171 clinical isolates of Salmonella isolates collected between 2011 to 2016 from a tertiary care hospital in Chennai, India were included. Antibiotic susceptibility testing and screening for extended-spectrum β-lactamase production was performed. Genes encoding resistance to β-lactam antibiotics (blaTEM, blaSHV, and blaCTX-M), chloramphenicol (cat, cmlA, and floR), co-trimoxazole (sul1, sul2, sul3, and dfr), and tetracycline (tet(A), tet(B), tet(C), tet(D), tet(E), and tet(G)) were detected using PCR and nucleotide sequencing analysis.
Results: The majority of the isolates were susceptible to ACCoT antibiotics, cephalosporins, and carbapenems. Most of the isolates were resistant to nalidixic acid and 1.7% were sensitive to ciprofloxacin. All the isolates (n=171) were negative for ESBL. Multidrug resistance was seen in 4.1% isolates and all the MDR Salmonella isolates were found to contain blaTEM-1(TEM-1-type β-lactamase), cat, dfrA17, sul1, and tet(B) genes.
Conclusion: We have observed a low MDR prevalence and reduced susceptibility to the fluoroquinolone, ciprofloxacin. This changing susceptibility pattern of Salmonella species over time warrants continuous monitoring and judicious use of antibiotics to prevent the emergence of resistant strains.

Authors: Bokre Santosh Rohidas , Deshpande Sangita , Waghmare Anil Raosaheb , Shete Anjali
Published: June 2022

Introduction:

Air pollution is a major environment related health threat. Air quality crisis in Indian cities is mainly due to emission from vehicles which include various particles and gases from vehicular emission. Traffic policemen who work in the busy traffic signal areas for years together are constantly exposed to this pollutant making them susceptible to its adverse effects, like respiratory and cardiovascular diseases.

Objectives:

To compare different parameters of pulmonary function test (PFT) between non-smoker controls and non-smoker traffic policemen, and also between smoker controls and smoker traffic policemen.

Methods:

This study was carried out in Department of Physiology among the government servants not exposed to traffic pollution and traffic policemen exposed to vehicular pollution. PFT was conducted in both these groups and parameters like vital capacity (VC), FEV1-force expiratory volume at the end of 1 second, ratio of forced expiratory volume at first second to forced vital capacity (FEV1/FVC%), mid-expiratory flow rate (FEV25-75%) and peak expiratory flow rate (PEFR) were measured and compared between these two groups.

Results:

In the present study, traffic policemen (non smoker) showed a statistically significant reduction in VC, FEV1, FEV1/FVC%, FEV25-75, and PEFR compared to controls (non smoker) whereas traffic policemen (smoker) showed a statistically significant reduction in VC, FEV1, FEV1/FVC%, FEV25-75%, and PEFR compared to controls (smoker).

Conclusion:

Significant reduction in all the parameters in traffic policemen compared to control group proves that preventive measures like pollution masks, regular breathing exercises, etc., have to be implemented at the workplace to reduce health hazards of continuous exposure to traffic dust.
Package Inserts
Authors: Anantharamu Tejus , Narain Narain Shankar , Mathur Adesh Govind , Roy Pramod , Gupta Atul
Published: June 2022

Background:

The information regarding the prescribed medication has to be given to the patients who consume the same. Most medicines now need a valid prescription for dispensing by a registered pharmacist. This chain of medicine distribution takes away the decision-making rights of the consumers, thereby greatly increasing the responsibility of the prescribers and dispensers. The availability of Package Inserts (PIs) has been made mandatory by most agencies globally.

Materials and Methods:

Each saleable unit of all the available medicines in the medical stores were analyzed for the availability of the PIs. The medicines for which PIs were available were classified into those manufactured within India and outside. All the PIs were assessed for their completeness.

Results:

Only a minor fraction (20.9%) of the saleable units of the available medicines carried PIs. All PIs carried information on therapeutic indications including posology and method of administration. The main difference between the imported and indigenous medication PIs was with regard to information on antidotes for overdosings, list of excipients, incompatibilities, shelf life, and specific instructions for use/handling.

Conclusion:

The availability and quality of PIs must be checked regularly by the concerned regulators and suitable punishment clauses must be introduced through legislations to ensure all manufacturers to adhere the same. The ultimate goal of good PIs must not only be to provide information to health care professionals but also to enhance the knowledge of the healthcare consumers to make informed decision-making and thereby enhancing the quality of healthcare.
The effects of different radiofrequency energy magnitudes on mucociliary clearance in cases of turbinate hypertrophy
Authors: Karatas A. , Salviz M. , Dikmen B. , Yuce T. , Acar G.
Published: June 2022

Background: Radiofrequency ablation (RFA) application is a commonly used technique for the treatment of inferior turbinate hypertrophies. As the number of RFA applications has increased, some problems have been reported regarding the patient discomfort. The most frequent problems among these are the extended turbinate crusting and nasal obstruction. Methods: Patients who received RFA were divided into two groups based on the applied energy value during the employment of the technique. Each group was including 30 patients. The patients in the first group received 8 watts and those in the second received 12 watts of energy. Saccharin transport times (STT) were measured four times. First a baseline measurement was performed followed by measurements on the 15th, 30th, and 45th days after the initial procedure. Nasal obstruction was twice assessed by peak nasal inspiratory flow (PNIF) measurements, which were taken both before the procedure and on the 45th day after the procedure. Turbinate surface crustings that were observed for more than 15 days were considered as an extended turbinate crusting. Results: The STT and PNIF measurements taken before the procedure were not significantly different between the two groups. Postprocedure STT measurements were significantly higher than the preprocedure measurements taken in both groups, and were stable within the physiological range. The STT increase in Group II was significantly greater than in Group I. Postprocedure PNIF values in both groups were significantly higher than the preprocedure values. Group II had showed a significantly higher rate of crusting. Conclusion: Higher magnitudes of energy elongate the healing process of the turbinate tissue and they affect more extensively the mucociliary clearance. Elongation of the healing process of the turbinate tissue may increase the rate of postprocedural complications such as turbinate surface crusting.

Authors: Onoyima C. C. , Okibe F. G
Published: June 2022

Multivariate statistics was used to analyse the physico-chemical properties of soil in the selected locations of the floodplain of River Kaduna in Niger State, Nigeria. Samples were collected in March and September of the same year and the levels of some important soil quality parameters analysed. The data was subjected to basic statistics, cluster analysis (CA), Principal Component Analysis (PCA), Correlation Analysis, and Discriminant Analysis (DA). Descriptive statistics shows that, with the exception of silt and clay other parameters analysed decreased in value after flooding, while the predominant textual class of the soil is clay-loam. The PCA for March and September sampling periods extracted three components each which explained 84.10% and 78.90% respectively of the total variance. Cluster analysis yielded five distinct clusters for March: cluster 1 (K, Ca, EA, and pH); cluster 2 (OM, CEC, TN, Silt content, Clay content, and OC); cluster 3 (Na); cluster 4 (P), and cluster 5 (Mg and Sand content); and five separate clusters for September. From DA, seven variables (pH, OC, OM, TN, P, K and Mg) were the most significant parameters which accounted for the expected spatial/temporal variations in the soil of March, while CEC, Na, Ca, silt, sand and clay become an important discriminator in September. Flood has significant influence on the soil of the study area as level and distribution of the parameters changed from March to September.

The drainage basin analysis is important in any hydrological investigation such as study of hydrologic processes, management of wetlands, flood, erosion and landslides susceptibility studies, assessment of groundwater potential and groundwater management. Also, existing theories and models such as the laws of drainage composition can be verified. In the light of the foregoing, the present paper describes the drainage characteristics of the lower Enyong Creek, which is underlain by varying geologic formations. viz; Asu River Formations e.g the Abakiliki Anticlinorium to the recent alluvium in the south It involved detailed map-based quantitative analyses of two 4th order sub-catchments in the study area. The drainage pattern is mainly dendritic type. It is observed that the drainage density value is low which indicates the basin is highly permeable subsoil and thick vegetative cover. The elongation ratio value reveals that the basin is strongly elongated and stream abstraction process constrained by heterogeneous geologic materials. This study would help the local people to utilize the resources for sustainable development of the basin area.

ABSTRACT

Cau Duc pineapple is one of the key products of Hau Giang province with 04 products that have been certified as 03-star OCOP. However, the production and consumption of the pineapple industry is still limited. Therefore, the study conducted interviews with 78 observations including actors in the value chain. By using value chain analysis tools, the research results show that the distribution channel through middleman still share the highest proportion, accounting for about 89%, the rate of contract farming between farmers and enterprises is quite limited. Distribution channel through community-based tourism has contributed to bringing high added value to farmers. Regarding the production cost structure of pineapple, the research shows that the cost of pineapple seedlings, fertilizer and hired labor account for a large proportion of the total cost. To develop the livelihoods of pineapple farmers, it is inevitable to reduce production cost, especially seedling costs and to promote the application of mechanization to reduce hired labor costs.
Khmer printed character recognition using attention-based Seq2Seq network
Authors: Buoy Rina , Taing Nguonly , Chenda Sovisal , Kor Sokchea
Published: June 2022

This paper presents an end-to-end deep convolutional recurrent neural network solution for Khmer optical character recognition (OCR) task. The proposed solution uses a sequence-to-sequence (Seq2Seq) architecture with attention mechanism. The encoder extracts visual features from an input text-line image via layers of convolutional blocks and a layer of gated recurrent units (GRU). The features are encoded in a single context vector and a sequence of hidden states which are fed to the decoder for decoding one character at a time until a special end-of-sentence (EOS) token is reached. The attention mechanism allows the decoder network to adaptively select relevant parts of the input image while predicting a target character. The Seq2Seq Khmer OCR network is trained on a large collection of computer-generated text-line images for multiple common Khmer fonts. Complex data augmentation is applied on both train and validation dataset. The proposed model’s performance outperforms the state-of-art Tesseract OCR engine for Khmer language on the validation set of 6400 augmented images by achieving a character error rate (CER) of 0.7% vs 35.9%.

Published: June 2022

The evaluation of reforestation for ecological restoration purposes in an area requires the comparison of similarity indicators with nearby reference forests. The objective of this study was to compare the vegetal composition, structure, falling debris, and their decomposition in the soil of a reforestation site of Eucalyptus camaldulensis Dehnh, planted more than 50 years ago, and a neighbouring forest dominated by Quercus deserticola Trel. and Q. laeta Liebm (used as reference), in an area of the State of Mexico; and obtain quantitative indicators of the trajectory of rehabilitation through the use of non-native species of Mexico. In reforestation and oak forest, we established 12 sampling sites where the composition, structure and two ecological processes (falling debris and decomposition) were determined. In addition, solar radiation was estimated by taking zenith photos of the canopy, using a hemispherical lens. When data was within normal distribution, we used the Student test, and when it was not, the Wilcoxon test was used to compare the variables studied. The reference forest outperformed reforestation (p ≤ 0.05) in: richness (68 and 50 species); diversity (Simpson index, 1.6-2.6 and 0.7-2.3); normal diameter (21.3 and 13.7 cm), accumulated leaf litter (18.2 and 9.2 Mg ha-1), detritus fall (0.606 and 0.321 Mg ha-1 per month), and litter decomposition (0.443 and 0.251 Mg ha-1 per month). Reforestation had a higher total radiation (5384 vs. 4376 MJ m-2 year-1) and tree height (8.1 vs. 7.4 m). The percentage values of importance were 32.8 and 26.9 % for Quercus deserticola and Q. laeta in the oak forest, and 70 % for E. camaldulensis in the reforestation. After 50 years, reforestation still showed statistical differences from forest in composition, structure, and soil processes.

stylistic study of patterned repetition in Ghanaian hiplife lyrics
Authors: Nkansah Samuel Kwesi
Published: June 2022

This study is a stylistic analysis of the dominant patterned repetition – schemes – in Ghanaian Hiplife lyrics. Schemes constitute a broad range of repetitive structures in literature. They represent the grammatical or linguistic breach of expressions, literally, to allow further emphasis and attention through some elements of repetition manifested in the phonological, graphological or formal patterning of these expressions. Data for this study came from fourteen hit Hiplife songs released between 1994 and 2018. The data were analysed within Leech’s (1969) framework for the stylistic analysis of schemes. The analysis revealed that both free repetition and parallelism were used in the data. Free repetition manifested in various kinds, such as epizeuxis and ploce, while epistrophe, symploce, anadiplosis and epanalepsis were the kinds of parallelism found in the data. These schemes were used to achieve an aesthetic effect and also highlight the necessity borne out of spontaneity and artistry of delivery of message. The paper has implications for literary studies in schools as the data are readily available and familiar to current students Again, it has huge relevance to African Stylistics as the concept has been generally seen as alien to the African context.

Nano Composites (nano MMCs) exhibit outstanding engineering properties like wear resistance, better stiffness, low density, and excellent ratio of strength to weight and so on. Unhybrid and hybrid nano MMC composites were fabricated using liquid metallurgical stir casting technique. Turning of Al2219 through TiN coated carbide tool was carried out to investigate surface roughness and cutting forces, by considering the cutting parameters like feed rate and speed. Response surface methodology (RSM) was used to design the experiments and to analyze the obtained results. The obtained results indicated that the cutting forces and surface roughness increases with increase in feed rate and decreases with increase in cutting speed. RSM displayed model and measured values are truly close to each other, which shows that created model can be effectively used to predict the cutting force and surface roughness on turning of MMCs. The predicted model values and obtained experimental values were close to each other with minimal error of 5 %, so the model is adequate.

HIGHLIGHTS

Nano Metal Matric Composites reinforced Al2219 with n-B4C & MoS2 particles successfully using stir casting

Feed rate is the key influencing factor and the cutting speed had slight influence on cutting force, surface roughness and tool wear

The experimental values obtained and predicted modeled values are within 5 % of each other, then the model is adequate

Published: June 2022

The aim of this research is to experimentally study the application of powder coating sludge (PCS) and metakaolin as geopolymer. The PCS is a lot of waste which is released after the powder coating production process. While metakaolin comprises SiO2 and Al2O3 which can be used to produce geopolymer. Therefore, this study aimed to determine a suitable geopolymer mix ratio, using PCS as part of the mixture. This research also investigated the effect of metakaolin/PCS ratio, sodium hydroxide (NaOH)/sodium silicate (Na2SiO3) ratio, curing time, NaOH concentration and solid/liquid ratio on compressive strength of geopolymer. The coefficient of thermal conductivity was tested by using a suitable composition. Kaolin in this experiment was calcined at 700 °C for 2 h. Alkaline activators for molding were NaOH and Na2SiO3. Samples were hardened in an electric oven at 80 °C for 4 h before being removed from the moulds and cured at room temperature within 7, 14 and 28 days. Metakaolin/PCS ratios of 90:10, 80:20, 70:30 and 60:40, and solid/liquid ratios of 0.8 and 0.6 were performed. Concentration of NaOH were 6, 8, 10, 12 and 14 molars and NaOH/Na2SiO3 ratios were 1:1.5, 1:2 and 1:2.5, respectively. The experiments were conducted in triplicate. Results of 3 PCS tests showed that the highest composition of Al2O3 and SiO2 were 3.37 and 1.99 % w/w, respectively. The sample which is based on 60 % metakaolin and 40 % PCS, 10 molars NaOH, NaOH/ Na2SiO3 of 1:1.25, solid/liquid of 0.6 and curing time of 28 days had a maximum compressive strength of 81 kg/cm2, while the coefficient of thermal conductivity was 0.1766 W/(mk). Therefore, it can be concluded that the PCS has the potential to partially replace metakaolin as geopolymers material.

HIGHLIGHTS

Geopolymer comprises alumina (Al2O3) and silica (SiO2) and the advantages of geopolymer production are environmentally friendly and reduce energy consumption 

The appropriate metakaolin/PCS ratio and concentration of activators provide the highest compressive strength

The geopolymer of this study has low thermal conductivity coefficient therefore it is a good insulation material
A Recursive Ant Colony Optimization Algorithm for Energy Consumption in Cloud Computing

Published: June 2022

The Cloud Computing (CC) has vast amount of data centers that consists of many computing nodes and consumes a huge amount of electrical energy. Hence the researchers found that the high service-level agreements (SLAs) violations and Energy Consumption (EC) are the major challenging issues in CC. The various traditional approaches reduced the EC, but ignored the SLA violation during the selection of Virtual Machine (VM) from overloaded hosts. In order to effectively deal with these issues, this paper proposed the Recursive Ant Colony Optimization (RACO) in 2 different workloads. The main aim of the RACO is to minimize the high EC and SLA violations by the movement of best ant, which is random and identified the distance between their movements. The algorithm consists of 3 major steps includes tracking and updating the pheromone and finally city selection. The proposed method simulated on Cloud Sim to validate the efficiency and stability of the proposed RACO and their performance compared to that of other existing techniques. The results showed that RACO reduced the EC by 40 - 42 % (approx.) which is less than the traditional ACO algorithm in Planet Lab data.

HIGHLIGHTS

Reduced EC and SLA Violation of Data Center are done via RACO

VM Allocations are done by IQR and utilises micro, small, medium and extra-large instances

Pheromone Tracking, updating and city selection are the endeavours of RACO

RACO reduced EC by 40 - 42 % and SLA Violation

This research was carried out in Afd II Village, West Bilah District, Labuhan Batu Regency, starting in October 2021. The aim of the study was to determine the effect on the growth of Red Chili (Capsium Annum L) plants on cutting shoots on chili leaves. Chili is a staple for consumption in everyday life. Chili peppers can be made more productive by using the right gardening techniques. Maintenance measures such as cutting shoots of chili plants with a dichotomous are one approach to increase chili yields. Pruning dichotomous shoots seeks to remove less productive plant parts to maximize. This study used a completely randomized design (CRD) with 4 treatments with 5 replications, in order to obtain 22 experimental units, each bed planted with 30 chili plants. The total number of plants is 30 x 5 = 150 plants. For the experimental unit, 3 were selected to be used as plant samples. From the observations, if the F test shows a significant effect, it will be continued with the Duncan' New Multiple Range test (DNMRT) at a 5% significance level. As treatment, namely: A = Pruning 7 DAP, B = Pruning 4th branch, C = No pruning, D = Pruning 14 DAP. Cutting the tops of leaves to increase the yield of the red chili, the results of the study concluded: 1. Red chili plants that were trimmed branches made the chili plants taller, 2. Trimming leaves caused the emergence of new leaf blades to increase 3. And cutting leaf shoots was useful for improve the yield of chili plant quality. Based on the results of the study, it is recommended to trim the 4th branch because it can increase growth.

The specific characteristics of life course and past experiences of LGBT+ old people require knowledge and awareness on the part of carers. In this paper, an international perspective to shed light on key issues in the field of inclusive care for LGBT+ older people is used, with a particular focus on the Slovenian context, drawing extensively on the findings of the European project “Being me” (2018–2020). In the project, we aimed to explore best practice in the area of education and to develop online learning materials and tools for social and health care workers. Among the principles and approaches that guided our research, the focus was put on intersectionality, resilience, strengths perspective, life stories, and collaboration with LGBT+ old people in all phases of the project.
