Gouverner les hommes : généalogie de la violence chez Ibn Khaldûn
Authors: Molino-Machetto Cédric
Published: August 2022

Ibn Khaldûn a souvent été présenté comme un précurseur du matérialisme historique : le Machiavel ou le Marx arabe du XIVe siècle. Matérialiste, il l’est indéniablement dans sa méthodologie : l’origine du pouvoir est pensée à partir de la nécessité de contraindre les hommes à coopérer pour qu’ils puissent se reproduire dans leur existence matérielle. Mais à partir de son étude anthropologique des sociétés tribales et des sociétés étatiques, il a développé une analyse originale du pouvoir et de son corollaire : la violence. Le politique peut se concevoir, à partir de l’œuvre d’Ibn Khaldûn (de sa Muqaddima en particulier), comme l’organisation et la coordination de la violence. Celle-ci est vectrice d’unité sociale grâce à l’esprit de corps dans les sociétés tribales en étant dirigée vers l’extérieur : l’attaque des tribus ennemies et la défense de la communauté. Dans les sociétés étatiques, l’affaiblissement de l’esprit de corps nécessite l’établissement d’une autorité politique (wazi’), qui dirige la violence vers l’intérieur comme régulation de l’agressivité naturelle. Loin d’être la négation du politique, la violence est consubstantielle au politique : elle est la condition de possibilité de la préservation d’une totalité et d’une unité sociales. Lorsqu’un groupe social perd sa capacité de violence, la communauté s’effondre, à l’image de la ville de Damas ravagée par les troupes de Tamerlan sous les yeux impuissants du philosophe.

Published: August 2022

The complex society is a human organization in which the number and variety of internal and external relationships are multiple and intertwined. The global unification of people's behaviors, lifestyles and thinking takes place, often through adaptation to Western standards and habits of life. Consequently, the educational action must be reviewed (with respect to all contexts of application: formal, informal and non-formal) in order to enhance the multidimensional balance and enhance uniqueness. Cultural values have a significant role in the functioning of societies and their social institutions. They serve as a guide to the ideals and behavior of the members of a culture Deardorff's (2006) model of intercultural competence is extremely explanatory of the "contagion" effect generated by individual actions of intercultural sensitivity. For this reason, it is believed that in classes with a mixed cultural background an effective model to be used is Flipped inclusion, an alternative method of teaching / learning with a view to continuing education

Published: August 2022

Diabetes has been linked to a wide range of genetic abnormalities or disorders like Cushing syndrome, Wolfram’s syndrome. The factual significance of these relatively uncommon disorders originates from the knowledge that supplies into the potential processes driving prevalent diabetes. Diabetes-related syndromes are presently classified based on clinical and biochemical characteristics. However, until now, no expertise classification strategies are developed for classifying diabetes-associated syndrome disorders efficiently and accurately. Thus, we introduce an Artificial Neural Network framework based on CapsNets to categorize vital genetic disorders related to diabetes. Here, a capsule represents a bundle or set of neurons used to retain data about an essential subject and provides precise information in each image. The suggested approach was systematically compared using cutting-edge methods and basic classification models. With an overall 91.4 percent accuracy, the proposed CapsNets-based method provides the best sensitivity89.93%, specificity 90.77%, and F1-score value 93.10%

Authors: Buhari Bello Alhaji , Obiniyi Afolayan Ayodele , Junaidu Sahalu B. , Kana Armand F. Donfack
Published: August 2022

This research performs a literature survey of remote user authentication researches based on smart card and external memory. The main security confidence of smart card based schemes is temper-resistance property. Other reasons are small physical size, portability, convenience of non-volatile memory, and security provided by a single chip computer embedded in a plastic card. The most efficient schemes are those that used hash function or ECC. The high cost of the cards and readers and their deployment remains a burden to issuers or users. This is what motivates the use of external memory instead of smart card. But the problem of non-temper resistance property associated with external memory limited researches in that direction. There are also, absence of other activities that are essential in user authentication such as forgot/reset password and re-registration in case the external memory or smart card is stolen or lost in all the reviewed researches.

Authors: Ejaz Noveed , Mansoor Muhammad
Published: August 2022

During aircraft startup, abnormal noise was heard at 100-200 RPM and the aircraft was switched off. On detailed inspection, damage and deformation was found inside the starter fairing, intakes and tail pipe. The failure analysis revealed that the damages were due to the engagement of some stock during rotation, which could be an internal engine’s object. The failure of the bearing inner race was subsequent. The fracture features of shaft were similar to the torsional overload; the fracture was started from a notched region. It was also the consequence of internal object damage.

Published: August 2022

The objective of the present research is to investigate the degradation phenomenon of Polyvinyl Chloride (PVC) cable jacket exposed under accelerated thermally aged at 100°C for 4 days then irradiated under n’s flux of 1.5x 1011n’s / cm2.sec for 1 hr in PARR-2 reactor at PINSTECH. Thermal, mechanical and chemical etc. properties of degraded cable jacket were studied with respect to fresh sample. It was examined that plasticizer content in PVC matrix started to deplete under the effect of temperature which made the matrix more rigid. In addition, the interaction of radiation with polymeric chains weakens the hydrocarbon bonding. The hydrogen and chlorine ions ejected from PVC molecular chains recombine to form hydrogen chloride (HCl) which induces porosity by creating localized pitting. This phenomenon is known as dehydrochlorination which created scissioning in PVC materials. Hence, due to the synergistic effects of temperature and radiation aging, cracks were observed on the outer surface of cable jacket in 2 years equivalent time. This study concludes that cables having PVC insulation are not suitable for long term exposure (i.e. decades) in thermo-irradiation environment.

Authors: Nguyen Vu Viet Linh , Pham Gia Quynh Nhu , Nguyen Thi Hong Anh , Nguyen Van Cuong
Published: August 2022

Polyphenolic chemicals found in tea leaves are frequently used in pharmaceutics and the food industry. Catechin is a polyphenol that has antimicrobial, antioxidant, and antibacterial effects, as well as other health advantages. The goal of this study was to create a catechin-encapsulated alginate hydrogel (Cate-ALG) that would protect catechin from degradation and bioactivity loss in stressful environments while also delivering catechin. The antioxidant ability of catechin was found to be greater than that of vitamin C using the 2,2-diphenyl-1-pierylhyrazyl assay. The FT-IR spectra revealed the distinct peaks of catechin and alginate. Additionally, due to the hydrogen bond interaction between alginate and catechin molecules, frequency downshifting was observed in the carbonyl and hydroxyl regions. Furthermore, release profile revealed a burst release of 5% catechin-ALG in the first 25 min. On the other hand, the 3% Cate-ALG approached the controlled release profile of catechin and increased the release time by more than 40 minutes. The catechin in alginate hydrogel has the potential for controlled release via transdermal and wound dressing applications.

This scientific study deals with the main issues related to the process of filling inhomogeneous materials into a rectangular hopper. The article develops an algorithm for filling particles of structurally inhomogeneous materials. A micrograph of the structure of samples of inhomogeneous materials is presented. It was found that the structure of samples of heterogeneous materials consists of three layers: external, internal and impurities of various grinding aggregates. Based on microstructural analysis, the presence of particles of various shapes and sizes was justified. On the basis of which the main initial conditions for filling the package with spherical particles were described. The basic physical and mechanical properties of structurally inhomogeneous materials were studied using the obtained results. We also constructed an approximate dependence of porosity on the particle diameter of inhomogeneous materials.

Published: August 2022

Most chemotherapeutic drugs are unable to distinguish between healthy and cancerous cells, resulting in the risk of side effects and drug resistance. There is a continuous effort to find new agents to help bring this disease under control. Compounds with bioactive natural product scaffolds have been of great interest due to their low toxicity and high efficacy. In this study, new naphthalene-based chalcone 1 and pyrazoline 1A compounds were synthesized via a Claisen-Schmidt condensation and cyclo-condensation reaction, respectively. These compounds were characterized using the Fourier Transform Infrared (FT-IR), 1H, and 13C Nuclear Magnetic Resonance (NMR) spectroscopy. The molecular docking activities were performed to study the interactions between these new compounds with breast cancer protein, 3ERT as estrogen receptor-α (ERα). Chalcone 1 and pyrazoline 1A compounds obey Lipinski's rule whereby pyrazoline 1A showed the lowest binding energy of -9.47 kcal/mol, inhibition constant of 113.93 mM and log P of 2.30. Interaction of pyrazoline 1A with 3ERT protein exhibited the hydrogen bonding with GLY521 amino acid, while the hydrophobic interactions were observed with LEU346, LEU384, LEU391, LEU525, LEU387, MET343, ALA350, and MET421 amino acids. Pyrazoline 1A is expected to show promising activities as an anticancer agent.

Modulating the Nordic Hamstring Exercise From “Zero to Hero”: A Stepwise Progression Explored in a High-Performance Athlete
Authors: Alt Tobias , Roos Tilman , Nolte Kevin , Modenbach Dominik , Knicker Axel J. , Jaitner Thomas
Published: August 2022

Background

The Nordic hamstring exercise (NHE) is commonly implemented to selectively improve eccentric knee-flexor strength. However, the standard version of the exercise (leveled shanks, extended hip joint) is too strenuous for most individuals, whose muscle activity rapidly decreases at extended knee angles. Hitherto, a gradual approach to the exercise has been missing. In this exploratory case study, we investigated elite performance to introduce a stepwise progression to the NHE.

Objective

To determine the extent to which exercise modifications (shank inclination, additional load, hip flexion) altered NHE mechanics.

Data Collection and Analysis

One male long jumper (age = 33 years, height = 171 cm, mass = 69 kg) with high-level expertise in the NHE performed 20 exercise variations. The corresponding kinematics, kinetics, and electromyographic activity of the biceps femoris long head (BFlh) and semitendinosus (ST) muscles were evaluated.

Results

Exercise variations demonstrated gradually increased peak moments from 69% (zigzag pose) to 154% (inclined bent single-legged version) versus a standard NHE. Shank inclination and additional load elicited small to moderate effects on peak moments, BFlh, and ST (0.24 ≤ d ≤ 0.72), whereas hip flexion largely affected all tested variables (2.80 ≤ d ≤ 6.66), especially muscle activity (BFlh = −63%; ST = −55% of maximal voluntary isometric contraction).

Commentary

These insights will help practitioners and scientists design multifaceted stepwise NHE progressions by creating differentiated stimuli that best match the strength capacities of individuals and address their specific needs.
The Additive Benefits of Aerobic Exercise and Cognitive Training Postconcussion: Current Clinical Concepts
Authors: Callahan Christine E. , Stoner Lee , Zieff Gabriel H. , Register-Mihalik Johna K.
Published: August 2022

Concussion induces the rapid onset of a short-lived neurophysiological disturbance that often results in autonomic nervous system dysfunction. This dysfunction affects both cardiovascular functioning and higher cognitive processing, inducing postconcussion clinical symptoms (somatic, cognitive, or emotional or a combination) and functional disturbances (impaired balance, cognition, and visual-vestibular performance). Current concussion rehabilitation paradigms using aerobic exercise may improve concussion symptoms. Additionally, cognitive training–focused rehabilitation interventions may enhance cognitive function postinjury. Though aerobic exercise and cognitive training–based concussion rehabilitation are successful independently, the multifaceted nature of concussion suggests the potential benefit of integrating both to improve concussion outcomes and clinician implementation. To support this clinical recommendation, we critiqued the existing research in which authors investigated aerobic exercise and cognitive training as postconcussion rehabilitation modalities, identified keys gaps in the literature, and proposed a practical clinical recommendation to integrate both modalities during concussion rehabilitation.
Hearing Status and Static Postural Control of Collegiate Athletes
Authors: Brancaleone Matthew P. , Talarico Maria K. , Boucher Laura C. , Yang Jingzhen , Merfeld Daniel , Onate James A.
Published: August 2022

Context

Because of the close proximity of the cochlea, vestibular apparatus, and shared neurovascular structures, the static postural control of athletes who are deaf or hard of hearing (D/HoH) may be different from that of athletes who are hearing. Limited research is available to quantify differences between these athletes.

Objective

To determine the effect of hearing status and stance condition on the static postural control of athletes.

Design

Cross-sectional study.

Setting

Athletic training facilities.

Patients or Other Participants

Fifty-five collegiate varsity athletes who were D/HoH (age = 20.62 ± 1.80 years, height = 1.73 ± 0.08 m, mass = 80.34 ± 18.92 kg) and 100 university club athletes who were hearing (age = 20.11 ± 1.59 years, height = 1.76 ± 0.09 m, mass = 77.66 ± 14.37 kg).

Main Outcome Measure(s)

Participants completed the Modified Clinical Test of Sensory Interaction and Balance on a triaxial force plate. Anteroposterior and mediolateral (ML) center-of-pressure (CoP) velocity, anteroposterior and ML CoP amplitude root mean square, and 95% ellipse sway area were calculated.

Results

Athletes who were D/HoH had a larger CoP velocity, larger ML root mean square, and larger sway area than those who were hearing (P values < .01). A significant main effect of stance condition was observed for all postural control variables (P values < .01).

Conclusions

During the Modified Clinical Test of Sensory Interaction and Balance, athletes who were D/HoH demonstrated a larger sway area compared with athletes who were hearing. Therefore, individualized baseline assessments of static postural control may be warranted for athletes who are D/HoH as opposed to comparisons with existing normative data.

Neurocognitive impairment is a major challenge globally because of the increasing proportion of older persons who are at risk. The condition is classified as either minor when one or more domains of cognition is/are affected without compromise of functional ability or major when both cognition and functioning are impaired. The important clinical types are mild cognitive impairment (MCI), vascular cognitive impairment (VCI) and dementia. In the sub-Saharan Africa, MCI affects between 7% and 39% of older persons, while the age-adjusted prevalence of dementia is 4.7%. About 50% of stroke survivors develop VCI and between 8% and 15% of these progress to vascular dementia. The risk factors include old age, vascular risk factors, frailty and stress. Suggested preventive strategies aimed at reducing the burden of dementia are based on the recommendations of the Lancet Commission on Dementia.

Despite its common prevalence, the etiology of schizophrenia is still elusive. Some studies suggest the involvement of several neurotransmitters, while some point out the role of genetics and environmental factors in the development of schizophrenia. Among varied proposed risk factors, several parental characteristics might constitute the risk factors for schizophrenia. Parental age, migration, and parental socioeconomic status are some of the suggested risk factors related to the development of schizophrenia in the offspring. This review aims to briefly discuss the three parental risk factors concerning the incidence of schizophrenia in the offspring.

Published: August 2022

Organic and non-organic illnesses may present with uncommon symptoms. In some cases, the presenting atypical symptoms make a prompt and accurate diagnosis difficult. Accordingly, unequivocal psychotic and affective symptoms also require adequate evaluation before determining the diagnosis and management. Here we present a case whose presenting symptoms strongly suggested an organic etiology, namely autoimmune psychosis, but failed to be diagnosed as such through laboratory tests and didn't respond to appropriate treatment. Re-evaluation of the case revealed significant past psychiatric history, suggesting functional psychosis but the patient did not respond to anti-psychotic medications either. This case therefore highlights the importance of complete unbiased work-up for all psychoses.

Authors: Baik Seung Min , Park Jin , Kim Tae Yoon , Choi Se Hong , Hong Kyung Sook
Published: August 2022

Background: Sepsis and septic shock remain the leading causes of death in critically ill patients worldwide. Various biomarkers are available to determine the prognosis and therapeutic effects of sepsis. In this study, we investigated the effectiveness of presepsin as a sepsis biomarker.Methods: Patients admitted to the intensive care unit with major or minor diagnosis of sepsis were categorized into survival and non-survival groups. The white blood cell count and serum C-reactive protein, procalcitonin, and presepsin levels were measured in all patients.Results: The study included 40 patients (survival group, 32; non-survival group, 8; mortality rate, 20%). The maximum serum presepsin levels measured during intensive care unit admission were significantly higher in the non-survival group (4,205.5 pg/ml [1,155.8–10,094.0] vs. 741.5 pg/ml [520.0–1,317.5], P<0.05). No statistically significant intergroup differences were observed in the maximum, minimum, and mean values of the white blood cell count, as well as serum C-reactive protein, and procalcitonin levels. Based on the receiver operating characteristic curve, the area under the curve for presepsin as a predictor of sepsis mortality was 0.764. At a cut-off value of 1,898.5 pg/ml, the sensitivity and specificity of presepsin for prediction of sepsis-induced mortality were 75.0% and 87.5%, respectively.Conclusions: Early diagnosis of sepsis and prediction of sepsis-induced mortality are important for prompt initiation of treatment. Presepsin may serve as an effective biomarker for prediction of sepsis-induced mortality and for evaluation of treatment effectiveness.

Published: August 2022

This study aims to describe the molecular characteristics of DNA barcodes in chocolate hind grouper (Cephalopholis boenak) in Indonesian waters with new sequence records from Madura Island waters. Partial sequences of the cytochrome c oxidase 1 (CO1) gene were successfully obtained from two samples of C. boenak in Madura Island waters. In contrast, the other sequences were obtained from the BOLD system database, covering the Islands of Bali, Lombok, and Ambon waters. The overall molecular analysis involved 10 C. boenak sequences with a length of 625 bp. The results indicated that the population of C. boenak in Indonesia waters has high genetic diversity, as evidenced by the value of haplotype diversity (Hd) = 0.956 and nucleotide sequence diversity (Pi) = 0.01746, in which the population is distributed into eight haplotypes. Results of phylogenetic tree reconstruction of neighbor-joining and maximum-likelihood indicate similar topology. The branching of NJ and ML phylogenetic trees of C. boenak in Indonesia waters is grouped into two geographical clades. Clade 1 with the subpopulations of the waters from Madura, Bali, and Lombok Islands. Clade 2 with the subpopulations of the waters from Ambon Island. The results of the median-joining network reconstruction depicted a similar topology with both phylogenetic trees.

The knowledge of the biological aspects and feeding activity of fish is required to manage the lack of data on fisheries. In this study, a total of 200 Plotosus canius were caught and examined to obtain information on their biological aspects, length-weight relationship, and feeding activity. The fish were captured using a gill net and traditional fishing trap called Bubu. Subsequently, all samples were examined for total body weight, total length, condition factor, gonad maturity, and feeding activity. The results showed that the specimens captured were 156 males and 44 females weighing between 95-280 gr and 117-214 gr with the length of 26-39 cm and 28-36.3 cm, respectively. The length-weight relationship showed a negative allometric growth pattern. The mean condition factors of males and females were 1.1048 and 1.0102, respectively. At the same time, the maturity level of gonads was at I and II. Moreover, it was discovered that most organisms in the digestive tract were shrimp, worms, small fish, and crabs, while the highest index of preponderance was in shrimp with 42%. In conclusion, this study showed the new information about length-weight, biological condition, and feeding habits of Plotosus canius, which can be inventoried to strengthen data on sustainable fisheries management.

Jackfruit (Artocarpus heterophyllus) is an underutilised plant that is promising in curbing food and nutritional security in sub-Saharan Africa. However, high level of secondary metabolites in its tissues significantly hampers its genetic characterisation for breeding purposes. Primarily, the compounds react with DNA during the extraction process, thus reducing its yield and quality. The utilisation of leaves from jackfruit seedlings is a potentially effective approach of addressing the challenge, however, limited information is available on efficient jackfruit seed germination procedures. Elucidating effective methods of jackfruit seed germination, and optimising protocols for DNA extraction is crucial in promoting its genetic characterisation studies for identification of superior varieties for propagation. The objective of this study was to evaluate methods of jackfruit seed germination, and DNA extraction procedures using jackfruit leaves. Pre-treatment of seeds with 3% hydrogen peroxide was effective in enhancing seed germination within a short time, compared to distilled water and 3% hydrochloric acid. We optimised a DNA extraction technique by combining CTAB-SDS based approach with an enhanced solvent extraction method. The technique yielded high quantity and quality of DNA from jackfruit leaves, which was appropriate for downstream polymerase chain reaction analysis. The sequence-related amplified polymorphism (SRAP) and simple sequence repeat (SSR) amplifications confirmed the effectiveness of the optimised CTAB-SDS based protocol for extraction of high quality DNA.

Vegetable soybean (Glycine max L. Merr.) is a highly nutritious crop in Africa whose attributes make it a product of choice to formulate diets with numerous human health benefits. The crop is still novel in West Africa, but is making inroads in many countries of the region. The objective of this study was to evaluate selected vegetable soybean varieties for agronomic performance and stability for fresh pod yield across Benin. Thirty-five vegetable soybean varieties were planted at three locations, namely Calavi, Grand-Popo and Sèmè, for two seasons. There was a significant variation (P < 0.05 ; P< 0.01 and P < 0.001) among genotypes for most quantitative traits; with highly significant environmental (P < 0.001) and GEI effects on fresh pod yield (P < 0.001). Genotype Maksoy 3N (15.9 t ha-1) had the highest fresh pod yield; while genotype AGS466 was the most stable across environments. Based on GGE, Sèmè-2 was the ideal environment for growing vegetable soybean in Benin. The study confirmed that vegetable soybean is well adapted to be grown in Benin and varieties AGS466, AGS346 and Ashorowase are candidates for wide cultivation in the country. Also, grain soybean varieties (S1079-6-7 and Maksoy 3N) are well suited to produce vegetable soybean in Benin.
"Am I American, Too?"
Authors: Assis Claudete Santana de , Moraes Antonio Henrique Coutelo de
Published: August 2022

The current work is aimed at analyzing the speech of nine Brazilian teachers who teach English as a Foreign Language (EFL) for three renowned institutions of English language teaching in the city of Recife, Pernambuco, so as to verify if the mental models built justify polarization of the groups denominated as groups of US and THEM (VAN DIJK, 2015a). Such polarization has occurred in a reverse way, since Brazilian EFL teachers look up to the American culture in detriment of their own. This polarization reversal was caused in Brazil, not only by the exposure to American products, but also by the country's historical context. The influence of the American government upon Brazil, and its hegemonic power, began effectively around the 1940s, when they established a Bureau in Brazil to foster cultural exchange. Nonetheless, its creation favored the implantation of the American hegemony, which was channeled by diplomatic agreements with Brazil, which were established by the American government and materialized by institutions along with the export of its English language. This research uses a qualitative, transversal and analytical methodology and analysis was guided in the light of Critical Discourse Studies, having Van Dijk (2015a) as the main theoretician. It will support us to comprehend the socio-cognitive discourse aspects and their components, using the discourse triangle proposed by the author, discourse-cognition-society, as well as Souza (2018) and Moita Lopes (2003) among others to understand the historical context of the North American culture coming to Brazil and the mental representations built subjectively.
Language centers as a language policy in a federal institute
Authors: Pereira Lauro Sérgio Machado , Costa Simone Maranhão , Silva Kléber Aparecido da
Published: August 2022

This paper analyzes the contexts of influence and design of the reference text for implementing a Language Center as part of the language policy (LP) and internationalization process of a Federal Institute of Education (FI) in the Northeastern Region of Brazil. The critical analysis based on Critical Applied Linguistics (CAL) and the Policy Cycle Approach (PCA) made it possible to perceive that the reference text points to a favorable and strongly driving environment for the design of Language Centers in the FI. Thus, the FI can institutionalize the LP actions already carried out unsystematically and individually by teachers of the mother-tongue and additional ones. The document allows the teaching agency to develop and implement projects that meet the local realities of the FI campuses. However, the reference text is involved in a naturalized-top-down internationalization perspective and focuses mainly on the offer of English courses. Moreover, we perceived the lack of investments for the document to be constituted in concrete actions and to assume a transforming role in the educational community.

Como resultado, verificamos que as políticas linguísticas para internacionalização da educação (PLI), no contexto dos IFs, apresentam-se de forma híbrida, com a coexistência de sentidos e práticas hegemônicas, não-hegemônicas e contra hegemônicas. Em outros termos, as PLI estão associadas à perspectiva crítica encapsulada no pensamento moderno/colonial/capitalista.

La asociación entre el perfil de patógenos causantes de mastitis en muestras de leche del tanque de almacenamiento y las prácticas de ordeño fueron evaluadas entre hatos con alta (n=15) y baja (n=14) calidad de leche. La categorización por calidad de leche se estableció a partir del recuento de células somáticas (RCS) y el recuento bacteriano (RB) según los datos de calidad de leche generados por la Oficina de la Reglamentación de la Industria Lechera de Puerto Rico durante los meses de agosto a septiembre de 2016. El perfil de los patógenos se determinó usando la prueba molecular PathoProof™ Mastitis Complete-16 Kit mientras que las prácticas de ordeño empleadas en cada hato se determinaron a través de un cuestionario cumplimentadopresencialmente. El análisis estadístico fue realizado con un PROC TTEST para determinar diferencias en los promedios del RCS y RB entre los grupos y tablas de contingencia para calcular la asociación entre las prácticas de ordeño y el perfil de patógenos causantes de mastitis según la categoría por calidad de leche. Diferencias entre los grupos de baja y alta calidad de leche fueron reportadas (P < 0.001) para los promedios del RCS (1,029,285 ± 76,879 vs. 212,667 ± 13,954 cél/mL) y RB (139,928 ± 47,474 vs. 4,440 ± 580.6 UFC/mL), respectivamente. Se detectaron diferencias entre las prácticas de ordeño en los hatos lecheros con alta y baja calidad (P < 0.05). Los patógenos causantes de mastitis con mayor prevalencia en hatos lecheros con leche de baja calidad fueron Streptococcus agalactiae, Corynebacterium bovis, Staphylococcus aureus y Klebsiella spp., con 92.9%, 71.4%, 57.1%, y 35.7%, respectivamente. Mientras que Serratia marcescens tuvo una mayor prevalencia, con 40% en hatos con leche de alta calidad (P < 0.05). El incrementar el conocimiento de los ordeñadores acerca de la influencia que tiene cada práctica de ordeño sobre la calidad de la leche es imperante para que los hatos lecheros produzcan leche de calidad.

Published: August 2022

The aim of this study was to identify the interests of young people in their occupation of free time that configures the experiences they have lived and to analyse what they would like to live in terms of leisure, but that, due to some impending factor, do not do so. The research is linked to a larger study: “Leisure in Brazil” that analysed the ways of living leisure in the national territory. The article dealt specifically with youth leisure in the southeast region and the information was collected through structured interviews. Despite the existing differences due to the socioeconomic situation, gender, and education of young people, we identified the relevance attributed to leisure in the company of friends, confirming the socializing and unifying role of groups through leisure. The analysis pointed out the economic and educational inequality, reflected in the access to leisure activities and justifies the need to abandon a homogenizing view of youth.

Authors: Olaiya Olumide O. , Modebei Mark I. , Bello Saheed A.
Published: August 2022

Fifth-order Korteweg-de Vries (KdV) equations, arise in modeling waves phenomena such as the propagation of shallow water waves over a flat surface, gravity-capillary waves and sound waves in plasmas. In this work, a one-step block hybrid linear multistep method was derived using the collocation technique, to solve fifth-order KdV models via the Method of Line (MoL). The consistency, stability and convergence of the method were established. The efficiency of the method can be seen from comparison of the exact solutions of problems and other methods cited from literature.

This paper proposes new methods and strategies for the propulsion of a mini Unmanned Aerial Vehicle (UAV). Typically, the UAVs are propelled by new technology batteries, fossil fuels, and hybrid systems. An experimental research regarding the usage of compressed air has been carried out. In total 13 nozzles have been installed to the fuselage of the UAV in terms of gaining 3-axis movement during flight. At the end of the manuscript, a MATLAB (Mathworks, US) program is provided in terms of calculating the maximum force and the flying time with the gained force. The UAV, whose design is presented, will be ideal for both defense and border security tasks, as it can move over the vehicle, has extremely high portability, and has a small physical footprint.
Porous Maize Stalk Cellulose Fiber-Reinforced Geopolymer Composites for Heat Insulation at the Bottom Side of a Local Electric Stove
Authors: Workiye Addisu , Woldesenbet Eyassu
Published: August 2022

The objective of this work is to develop porous maize stalk cellulose fiber-reinforced geopolymer composites for heat insulation on the bottom side of an electric stove using the solid impregnation method. Heat loss measurement is conducted using an infrared thermometer. Moreover, the temperature effect on the composites is investigated. The maize stalk cellulose fibers are very essential to anticipate the cracking phenomenon generated by high temperatures. The degradation of the fibers causes the formation of small cavities in the matrix, and thus leads to high temperatures. The experimental result shows that it takes 22 minutes to boil water using the proposed electric stove, whereas it takes 29 minutes using the existing local electric stove. By using the proposed electric stove to boil water, 113,793,148.104 KWh of energy per year at the national level can be saved.
Effect of Gear Materials on the Surface Contact Strength of Spur Gears
Authors: Eskezia Eniyew , Abebaw Misganaw
Published: August 2022

In gear applications, the initiation of cracks at or near the contact surfaces of gear mates occurs mostly due to the surface contact mode of gear failure. This study aims to investigate the influence of gear materials on the contact strength of spur gears. In this study, four different gear materials are selected and the contact stress on spur gear mates is analyzed. Hertz’s contact stress equation and ANSYS 16 are used for the theoretical analysis and finite element (FE) method, respectively. The results of Hertz’s equation are compared with the results of ANSYS 16. The results show that the contact stress on spur gear mates varies when different gear materials are used in both methods. This indicates that the surface contact strength of spur gears is greatly influenced by the type of gear materials.

There are various methods that can be employed to increase the lifespan and power output of photovoltaic (PV) systems. This study aims to increase the power output of a grid-connected PV system by using a water-cooling unit and solar reflectors. The PV modules of the current PV system are divided into two clusters. The first cluster, which is considered an improved cluster, has a solar reflector-cooling unit added to it, while the second cluster is used as a reference. The results show that the maximum efficiency and performance ratio values of the improved and reference PV modules at 10:30 AM are 14.7% & 13.7% and 97.5% & 91.2%, respectively. The maximum electrical power values of the improved and reference PV modules at 12:00 PM are 2.55 W and 1.69 W, respectively. The maximum gain value for electrical power is 43%.

Discord was started to solve a big problem: how to communicate with friends around the world while
playing games online.it’s a home for communities of any size,but it’s most widely used by small and
active groups of people who talk regularly. Discord is used by everyone from local hiking clubs, to art
communities, to study groups. Discord has millions of people creating places for their friends and
communities, talking for upwards of 4 hours per day on the platform. Discord is now where the world
talks, hangs out, and builds relationships. Discord lets anyone create a space to find belonging—just like
it did for Jason and Stan.People love discord because it’s a home for all their communities and groups of
friends.it’s a place where they can be themselves and spend time with other people who share their
interests and hobbies.In this Case study we are trying to resolve the following cases such as Why discord
keeps on the widely acceptable chance of global and local communication and How discord manages the
large crowd and their activities.
Implementasi Desentralisasi Dalam Pengelolaan Perikanan
Authors: Muhayat  , Rina Haslita
Published: August 2022

Since the early 1990s, various discourses have developed among government observers about government decentralization in Indonesia. Laws No. 22 and 25 of 1999 concerning Regional Government and Regional Finance, which were subsequently amended by Laws No. 22 and 33 of 2004, have led Indonesia to enter the process of decentralized governance after more than 30 years of being under the all-centralized New Order regime. The implementation of these two laws has become a momentum for the transfer of supervision, fiscal resources, political autonomy and responsibility for public services from the central government to local governments. Over the span of more than a decade of displacement, heterogeneous local experiences have surfaced, as central control over regions loosened. Local governments play a very important role in the implementation of decentralized fisheries management, apart from the central government, the community and other stakeholders with an interest in the fisheries sector, of course. They must be prepared to face challenges in managing the potential fisheries sector, so that there will be no more policies that harm the fishing community. So that the fishery sector is able to become the backbone of the country in eradicating poverty, injustice in government policies towards fishermen, and is able to become a contributor to foreign exchange for Indonesia.
