The Frequency Spectrum Analysis of Wideband Oscillations of Grid-Connected Voltage Source Converter
Authors: Wang Liyi , Cai Deyu
Published: June 2023

With the widespread application of voltage source converters (VSCs) in power systems with high renewable resource penetration, the problem of wideband oscillations caused by interactions between power converters and the power grid has drawn great attention. This paper presents a new methodology for simplifying the mathematical derivations of the impedance model of a VSC. Using the new simplified model, the stability and spectrum characteristics of the performance of the VSC can be clearly analyzed. The proposed second-order d-q impedance model of a grid-connected VSC in the presence of a PLL not only mathematically demonstrates that wideband oscillatory modes always occur in conjugate pairs, but also delivers a clear vision of the physical essence of these wideband oscillations. A classic modal analysis is executed in this paper to demonstrate the stability and frequency spectral characteristics of wideband oscillations in a VSC integrated system. The impact of the control parameters of the VSC on wideband oscillatory stability is thoroughly analyzed by modal analysis using ‘DIgSILENT PowerFactory’ as well as hardware-in-the-loop experiments. This methodology can be considered a powerful tool for the control design of VSCs in the modern power system.

Published: June 2023

It is well known that wind power generation addresses the energy needs of small and remote populations as one of the alternatives to petroleum-based energy’s greenhouse effect. Although there are several publications on rotor design and performance analysis, more should be written about the starting of wind turbines, mainly the small ones, where starting can be a big issue. The present paper evaluates the impact of the swept blade angle on the aerodynamic torque, thrust force, and minimal wind speed required to start the operation of a compact horizontal-axis wind turbine. It presents a novel investigation of the influence of swept rotor blades on the starting performance of a turbine drivetrain. The methodology uses the blade element moment theory coupled to Newton’s second law, in which Palmgren’s extended approach is employed. When the proposed methodology is compared to the experimental data available in the literature, it exhibits good agreement. However, when the wind turbine starts to run, the results show that swept blades do not always enhance the torque coefficient or reduce the thrust force as indicated in some scientific papers. For backward-swept blades, the maximum value decreases 4.0%. Similar behavior is found in thrust force for forward-swept blades. Therefore, more study is required to evaluate many blade foils in several operational environments to confirm this statement.

Published: June 2023

Doubly Uniparental Inheritance (DUI) is considered one of the major exceptions to the common rules of eukaryotic cell biology and germline formation. DUI is known in bivalves, which belong to the phylum Mollusca; conversely, no DUI evidence was found in some gastropod species. Investigating the presence of DUI in Nemertea is of particular interest given the fact that these spiralian animals are suggested to be a sister group of Neotrochozoa (i.e., Mollusca and Annelida). DUI species are normally detected as having two sex-associated mtDNAs, which can be highly divergent. In this work, the presence of sex-associated mitochondrial genomes was investigated in the nemertean species Notospermus geniculatus and no evidence was found for DUI. Even if these are preliminary results, negative evidence is still interesting because of the high importance of the DUI phenomenon in many research fields, where it plays a pivotal role in understanding eukaryotic evolution. For this reason, further research on DUI species detection should be highly encouraged, as well as the publication of negative results beside positive ones, as is the case for the present study, improving the knowledge on the biology and ecology of a broad spectrum of marine species.

Published: June 2023

The environmental regulatory mechanism underlying the coupling of leaf photosynthesis and transpiration in Artemisia ordosica, a typical desert shrub in China, remains unclear. To understand this mechanism, we measured the net leaf photosynthetic rate (Pn), transpiration rate (E), and stomatal conductance (gs) from May to October 2019 using a portable photosynthesis analyser. Photosynthetically active radiation, air temperature, relative humidity, and soil water content were simultaneously measured. Both E and Pn are positively correlated with gs. Pn and E exhibited a nonlinear quadratic correlation from May to July and a linear correlation in August and September. The changes in the maximum photosynthetic (Pn−max) and carboxylation rates were mainly affected by air temperature and light. Seasonally, Pn−max initially exhibited an increasing trend, peaking in June and then decreasing. Under low temperature and light conditions, Pn−E was linearly correlated and the coupling relationship was stable. Under higher temperatures and radiation, Pn−E exhibited a nonlinear quadratic correlation, and decoupling occurred with increasing temperature and light intensity. The results of this study provide a better understanding of the responses of desert shrub ecosystems to climate change.

Published: June 2023

The promotion of electric mobility has the potential to reduce several impacts of the road transport sector, such as increased emissions of greenhouse gas (GHG) and air pollutants and natural resource depletion. As such, decision makers and other stakeholders around the world have invested significant efforts in the transition to sustainable urban mobility based on the use of electric vehicles. However, there are few studies that investigate the potential benefits of electric mobility in all its facets; i.e., most focus on analyzing the benefits of replacing conventional cars while leaving aside other means of transportation with greater use and, consequently, higher emissions, such as, primarily, public transport and freight transport vehicles. Thus, this study aims to develop an action plan focused on electric mobility—APOEM, which stipulates gradual implementation steps in a time horizon of 5 years. For this purpose, a city with potential for electric mobility implementation called Atibaia, in the countryside of the State of São Paulo, in Brazil, is investigated. The results show that, in an ambitious scenario of electric vehicle deployment in the City of Atibaia, which presents energy supply compatible with demand, it would be possible to reduce a total of 30,788.70 tons of GHG in 5 years, and, as for emissions of air pollutants, it would be possible to reduce 140.38 tons of CO, 36.38 tons of NMHC, 1.58 tons of RCHO, 130.20 tons of NOx, 3.54 tons of MP and 0.75 tons of SO2 in 5 years. It is also worth noting that, in order for electrification to generate a greater contribution to the environment, it is necessary that electric mobility be generated from renewable energy sources.

Published: June 2023

Agriculture contributes the most to the economy and provides agro-ecological benefits in the environmentally unsustainable Aral Sea region, but its productivity is steadily dropping. To improve the resilience of farming communities in the region, crop diversification is proposed to enable farmers to grow high-value competitive crops and obtain more stable farm incomes. This study provides long-term, multidisciplinary analyses and strategies for strengthening crop diversification amongst farmers in the Aral Sea region. The study analyzed data provided by the Ministry of Agriculture of the Republic of Uzbekistan and the statistical yearbook of 2000–2020. According to the gross margin study findings, farmers who use diversified cropping systems made considerably higher revenues than farmers relying on mono-cropping practices. This study demonstrates that greater crop diversity contributes to the rational use of natural resources and optimization plans, environmental sustainability, and food security as important natural and socio-economic issues in this region. The study findings suggest that proper crop diversification strategies need to be developed in the Aral Sea region to improve the sustainability of farming systems with enhanced resilience to devastating environmental and climate challenges.
The Impact of Sound Pressure Level, Loudness, Roughness, Sharpness, Articulation Index, Hand Vibration, and Seat Vibration on Subjective Comfort Perception of Tractor Drivers
Authors: Wang Zhipeng , Zuo Yanyan , Sun Liming
Published: June 2023

Long-term exposure to high levels of vibration and noise can have detrimental effects on the health of tractor drivers. This study aimed to evaluate the subjective comfort experienced by drivers operating large-horsepower tractors. A total of 10 tractors sourced from 5 different manufacturers were subjected to testing. The assessment encompassed three operational conditions, namely, idle, maximum torque, and rated power. Objective measurements, including A-weighted sound pressure level (A-SPL), loudness, sharpness, roughness, articulation index (AI), hand vibration, and seat vibration, were collected. Additionally, subjective comfort evaluations were carried out using a paired comparison test. To predict the subjective comfort of tractor drivers, a novel prediction model was developed by employing a simulated annealing (SA) algorithm to optimize a backpropagation neural network (BPNN). The model successfully achieved accurate predictions of subjective comfort, yielding a maximum prediction error of 4.4%. The study findings revealed that vibration had a more pronounced impact on driver comfort in environments with lower-amplitude noise, whereas high-decibel noise exerted a masking effect on vibration-induced discomfort. In conclusion, the SA-BPNN model, utilizing A-SPL, loudness, sharpness, roughness, AI, hand vibration, and seat vibration as objective parameters, effectively predicted the subjective comfort of tractor drivers. This discovery holds significant implications for tractor manufacturers, who can employ the model to optimize the design of tractor cabs and enhance driver comfort.

The boundary layer flows exhibit symmetrical characteristics. In such cases, the flow patterns and variables are symmetrical with respect to a particular axis or plane. This symmetry simplifies the analysis and enables the use of symmetry-based boundary conditions or simplifications in mathematical models. Therefore, by using these concepts, the governing equations of the radiative flow of a hybrid nanofluid past a stretched and shrunken surface with the effect of a magnetic dipole are examined in this paper. Here, we consider copper (Cu) and alumina (Al2O3) as hybrid nanoparticles and use water as a base fluid. The heat transfer rate is enhanced in the presence of hybrid nanoparticles. It is observed that the heat transfer rate is increased by 10.92% for the nanofluid, while it has a 15.13% increment for the hybrid nanofluid compared to the base fluid. Also, the results reveal that the non-uniqueness of the solutions exists for a certain suction and shrinking strength. Additionally, the ferrohydrodynamic interaction has the tendency to reduce the skin friction and the heat transfer coefficients for both solution branches. For the upper branch solutions, the heat transfer rate increased over a stretching sheet but decreased for the shrinking sheet in the presence of the radiation. It is confirmed by the temporal stability analysis that one of the solutions is stable and acceptable as time evolves.

COVID-19 is primarily known for its respiratory tract involvement, often leading to severe pneumonia and exacerbation of underlying diseases. However, emerging evidence suggests that COVID-19 can result in multiorgan failure, affecting organs beyond the respiratory system. We present the case of a 62-year-old male with COVID-19 who developed acute liver failure (ALF) and rhabdomyolysis in the absence of respiratory failure. Initially, the patient presented with significantly elevated aspartate transaminase (5398 U/L) and alanine transaminase (2197 U/L) levels. Furthermore, a prolonged prothrombin time international normalized ratio (INR) of 2.33 indicated the diagnosis of ALF without hepatic coma, according to Japanese diagnostic criteria. The patient also exhibited elevated creatine kinase (9498 U/L) and a mild increase in creatinine (1.25 mg/dL) levels, but both values improved with intravenous fluid support and molnupiravir administration. To our knowledge, this is the first reported case presenting with both ALF and rhabdomyolysis associated with COVID-19. In addition, we review the existing literature to summarize previously reported cases of ALF triggered by SARS-CoV-2. This case report underscores the significance of recognizing COVID-19 as a significant contributing factor in the development of multiorgan failure. Furthermore, it suggests that COVID-19 can lead to severe illness, irrespective of the absence of respiratory failure.

Published: June 2023

The Zika virus (ZIKV) epidemic brought new discoveries regarding arboviruses, especially flaviviruses, as ZIKV was described as sexually and vertically transmitted. The latter shows severe consequences for the embryo/fetus, such as congenital microcephaly and deficiency of the neural system, currently known as Congenital ZIKV Syndrome (CZS). To better understand ZIKV dynamics in trophoblastic cells present in the first trimester of pregnancy (BeWo, HTR-8, and control cell HuH-7), an experiment of viral kinetics was performed for African MR766 low passage and Asian-Brazilian IEC ZIKV lineages. The results were described independently and demonstrated that the three placental cells lines are permissive and susceptible to ZIKV. We noticed cytopathic effects that are typical in in vitro viral infection in BeWo and HTR-8. Regarding kinetics, MR766lp showed peaks of viral loads in 24 and 48 hpi for all cell types tested, as well as marked cells death after peak production. On the other hand, the HTR-8 lineage inoculated with ZIKV-IEC exhibited increased viral production in 144 hpi, with a peak between 24 and 96 hpi. Furthermore, IEC had peak variations of viral production for BeWo in 144 hpi. Considering such in vitro results, the hypothesis that maternal fetal transmission is probably a way of virus transmission between the mother and the embryo/fetus is maintained.

The emergence of SARS-CoV-2 variants has posed a challenge to disease control efforts worldwide. This study explored the genomic diversity and phylogenetic relationship of SARS-CoV-2 variants reported in Pakistan. Our objective was to understand the transmission dynamics of different lineages within the country. We retrieved and analyzed spike protein sequences from Pakistan and compared them with reference sequences reported worldwide. Our analysis revealed the clustering of Pakistan-origin isolates in nine different clades representing different regions worldwide, suggesting the transmission of multiple lineages within the country. We found 96 PANGO lineages of SARS-CoV-2 in Pakistan, and 64 of these corresponded to 4 WHO-designated variants: Alpha, Beta, Delta, and Omicron. The most dominant variants in Pakistan were Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2, AY.108), and Omicron (BA.2.75, BA.5.2), and the N-terminal domain and receptor binding regions were the most hypervariable regions of the spike gene. Compared to the reference strain, characteristic substitutions were found in dominant variants. Our findings emphasize the importance of continuously monitoring and assessing nucleotide and residue substitutions over time to understand virus evolutionary trends better and devise effective disease control interventions.
Encouraging Water Protection through Donation: Examining the Effects of Intention to Engage in Personal Water Conservation Behaviors on Donation Behaviors

Published: June 2023

In many parts of the world, water scarcity is increasing due to climate change and the deterioration of the quantity and quality of water sources. In the southeastern U.S., water conservation is of particular concern because of the decades-long water war between the states of Florida, Georgia, and Alabama over two shared river basins. Individuals can only do so much to conserve water in their home, but different forms of donations can contribute to larger efforts resulting in greater environmental impact. Using a conceptual framework connecting self-identity to water conservation contribution engagement, the purpose of this study was to determine if personal water conservation behavioral intent impacted contributions to organizations supporting water conservation so effective communication strategies can be developed. Previous studies connected self-identity and intention to engage in pro-environmental behaviors, but there is a lack of research on the connection to water conservation donation behavior. Respondents were recruited to take an online survey using non-probability opt-in sampling. Self-reported intent to engage in water conservation behaviors, current contribution behaviors (if they donate to an organization that protects water, are a member of a water conservation organization, own a specialty license plate that supports water conservation, and volunteer for water conservation events), and total family income in the past year were obtained. Data were analyzed using point-biserial correlations and binary logistic regressions. The results indicated personal water conservation behavioral intent was positively correlated to water conservation contribution behaviors. Personal water conservation behavioral intent and income level were significant predictors of contribution behaviors. Environmental communicators and educators should encourage those who identify as conservationists to increase their self-identity through contributing to organizations. Future research should be conducted to determine if actual versus perceived discretionary income and/or time is a predictor of contributions.

Published: June 2023

Soil salinization can have an inhibitory effect on crop productivity and pose a serious threat to regional agricultural resource utilization and sustainable development. However, there are scarce studies on the quantitative impact of soil salinization on crop productivity. The purpose of this study is to identify the spatial and temporal characteristics of the cultivated land, the soil salinization degree, and the net primary productivity (NPP) of vegetation in the Shandong region around the Bohai Sea and to couple the quantitative relationship between soil salinization and the productivity of the cultivated land. We found that the amount of cultivated land in the study area gradually decreased from 2001 to 2019. The degree of soil salinization in the cultivated land in the north of the study area increased slightly from 2001 to 2005 and decreased continuously after 2011. The NPP value of the cultivated land increased, fluctuating from 2001 to 2019. The spatial distribution of the NPP value was generally lower in the north than in the south, with Dongying District as the boundary. In addition, in different soil salt content (g/kg) intervals, the change trends in cultivated land NPP varied. When the salt content of cultivated soil was in the range of 0–3 g/kg, 3–7 g/kg, or 7–15 g/kg, for every 1 g/kg increase in salt content, the NPP value decreased by 43.62 gC m−2a−1, 30.36 gC m−2a−1, and 44.19 gC m−2a−1, respectively. These results are expected to provide decision-making support for strengthening the dynamic monitoring and regulation of cultivated land salinization and promoting sustainable utilization of salinized cultivated land in the coastal areas to alleviate the food crisis.
Calculation of the SPI, SPEI, and GRDI Indices for Historical Climatic Data from Doñana National Park: Forecasting Climatic Series (2030–2059) Using Two Climatic Scenarios RCP 4.5 and RCP 8.5 by IPCC

Published: June 2023

In this study, we utilized three different indices to assess drought conditions in the Doñana National Park (DNP) located in southern Spain. These indices included the Standardized Precipitation Index (SPI), which is based on precipitation statistics, the Standardized Precipitation Evapotranspiration Index (SPEI), which incorporates both precipitation and air temperature data, and the Groundwater Recharge Drought Index (GRDI), a newly developed index specifically designed to evaluate groundwater drought. The analysis covered the time period from 1985 to 2015, and future projections were made for the years 2030–2060 under different climate scenarios (RCP 4.5 and RCP 8.5). Our findings revealed a significant decrease in total precipitation of approximately 13–14% compared to historical records (1985–2015). Moreover, severely to extremely wet periods exhibited a reduction ranging from 25% to 38%. A key contribution of this study is the application of the GRDI index, which allowed us to assess groundwater recharge rates. We observed a decline in the simulated mean recharge rates during the 21st century when compared to the historical period spanning from 1950 to 2009. This decline can be attributed to increased evapotranspiration. The results of this research provide valuable insights for the Spanish water resources administration. The observed reductions in precipitation and groundwater recharge rates emphasize the need for appropriate mitigation measures. The findings will aid the administration in formulating an integrated water resources management strategy in the Doñana National Park and its surrounding basin. By understanding the projected changes in drought conditions, the administration can make informed decisions to ensure sustainable water resource management in the region.
Microbial Community Structure, Metabolic Function, and Phenotypic Characteristics of Sediment in Deep Coal Mine Underground Environment, China
Authors: Chen Di , Feng Qiyan
Published: June 2023

Long-term coal mining has created unique microbial communities in deep coal mines. Revealing the microbial community structure and metabolic functions in the underground environment can contribute to a better understanding of the coal mine ecosystem. In this study, we collected underground sediment samples from producing mines in eastern China at mining depths of −400 to −1100 m and performed high-throughput sequencing. Results showed that most of the genera in the underground sediment can degrade organic matter, such as polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, and xylene, etc. The dominant genera in the underground sediment were Hydrogenophaga, Thauera, Pseudomonas, Rhodobacter, and Dietzia. Samples were divided into coal roadway (CR) and rock roadway (RR) groups according to the sampling location. The microbial community structure differed significantly (p < 0.05) between these two groups of samples, with the distribution of main genera in the CR group samples showing a negative correlation with Cu and a positive correlation with temperature. The samples from the CR and RR groups were significantly different (p < 0.05) in their metabolic functions, including membrane transport, metabolism of other amino acids, folding, sorting, and degradation. Microorganisms in the RR group samples showed high resistance to heavy metals, while microorganisms in the CR group had higher degradation functions of organic pollutants. Bugbase phenotypic predictions indicated a high potential pathogenicity of microorganisms in coal mine sediment, which was mainly contributed by the genera Hydrogenophaga, Pseudomonas, Geothermobacter, and Methylophaga, etc. This study deepens the understanding of microbial communities in deep coal mine environments; however, the organic contamination and biological health risks of underground environments require extensive attention.

Published: June 2023

The easy implementation of ecologically-sound remediation measures for the prompt stabilisation of burned areas may be crucial in Mediterranean forest environments. Manual in situ contour redirection of burned felled logs could aid in soil erosion control and facilitate forest self-regeneration. In this study, a plot-scale runoff/sediment yield survey was conducted in Calabria, Italy, within a Mediterranean pine forest that was affected by an extreme wildfire spanning over 15,000 hectares in the summer of 2021. The hydrological response to 24 rainfall events was analysed after one year of monitoring using nine Wischmeier and Smith 20% sloping plots, which were distributed into three plot-blocks representing different conditions (forested, burned with randomly directed fallen logs, and burned with fallen logs manually redirected along contour lines). The post-fire condition (with felled logs in random positions) exhibited a consistent overall increase (approximately four times) in runoff and sediment yield compared to the pre-fire situation. This degradation effect was mitigated by approximately 30% through the manual redirection of burned logs, which promoted early (three to five weeks) vegetation regeneration (including tree emergence) and enhanced coverage as vegetation spread from the log positions. The results obtained so far provide encouraging insights and warrant further research on steeper slopes and complementary aspects (regulatory, biological, mechanical, economic, etc.).

The priority task of the state policy is to preserve the labor activity of the population by ensuring safe working conditions, which, according to official reports, are not considered as such in most enterprises of the country, including in mining operations. The goal is monitor the state of working conditions of workers in the extraction of minerals in the Republic of Bashkortostan, comparing them with similar data for the Russian Federation and for the main types of economic activity. According to Rosstat data, at mining enterprises in the Russian Federation, the share of the number of employees employed in jobs with harmful and (or) dangerous working conditions increased by 9.8 % compared to 2011, in the Republic of Bashkortostan — by 13, 4 %, amounting to 55.1 % and 45.0 % of the total number of employees in the industry by 2020, respectively. For comparison with data on the main types of economic activity in Russia, the indicators increased by 6.8 %, in the republic — by 4 %. and noise. In addition, there has been a significant increase in the proportion of people working in contact with vibration and chemical factors in excess of the allowable values in the region. Studies show unresolved problems in the production of minerals, causing an increase in the proportion of workers with harmful working conditions, including certain factors of production, which will undoubtedly be reflected in the indicators of occupational and production-related morbidity, industrial injuries, including severe outcomes.

Zósimo de Panópolis e a alquimia antiga:
Authors: Barbieri Pedro
Published: June 2023

Zósimo de Panópolis (sécs. III-IV d.C.) foi um sacerdote-artesão egípcio cuja obra teve imensa importância para a alquimia antiga. Escrevendo em grego durante um período em que o Egito romanizado passava por uma queda de prestígio e incentivo das atividades nos templos, Zósimo discorre sobre práticas metalúrgicas lançando mão de todo um cabedal religioso e teórico, por vezes em simples receitas, por vezes em tratados e cartas (dirigidas principalmente a certa Teosebeia). O famoso Sobre a letra ômega, por exemplo, possui forte caráter sincrético; por meio dessa obra, Zósimo aponta diversos paralelos entre as tradições grega, egípcia e hebraica, reforçando a necessidade de uma abordagem espiritual à arte metalúrgica. Examino neste artigo alguns pontos principais de seus escritos a fim de apresentar Zósimo ao público interessado.
Increased levels of brain-derived neurotrophic factor in cultures of nervous cells treated with a selective serotonin reuptake inhibitor
Authors: Martins Fernandes Hotair Phellipe , Domingues Soares e Silva Sara , Moreira de Souza Adriano Junio
Published: June 2023

Introduction. The effects of antidepressants such as fluoxetine on brain plasticity are associated with increased transcription and signaling of trophic factors such as brain-derived neurotrophic factor (BDNF), which enhances synaptic and neurogenic processes. Objective. To evaluate whether treatment with fluoxetine could increase BDNF levels in retinal cells. Method. To conduct the experiment, retinas were dissected from neonatal rats and cultured in complete culture medium. Next, the cultures designated for the experimental group were treated with 1µM of fluoxetine and maintained for 2, 12, 24, 48, or 72 hours in vitro. The cultures designated for the control group underwent the same protocol, but did not receive the fluoxetine treatment. The levels of BDNF were determined by Western blot analysis, and the data were analyzed by Student's t-test to compare the two groups (control and experimental). Results. The results showed that cultures treated with fluoxetine for 12, 24, and 48 hours had significantly higher levels of BDNF than the control group. Conclusion. The findings suggest that treatment with fluoxetine may have potential therapeutic effects on retinal cells by increasing BDNF levels. This adds to the existing evidence on the role of BDNF in mediating the therapeutic effects of antidepressants and highlights the potential for further research on the use of antidepressants in the treatment of retinal diseases.
Du corps, chez les rois hellénistiques : corps guerriers

L’article traite du rôle des blessures dans la construction de la légitimité royale à l’époque hellénistique. Si les Anciens ont mis en valeur le rôle des blessures dans la construction de l’autorité du Conquérant, tel n’a pas été le cas pour ses successeurs. Il semble y avoir une convention historiographique romaine, qui explique l’insistance sur les cicatrices d’Alexandre tandis que les rois ont dû cacher le fondement militaire de leur domination afin d’être accepté par les cités. Il existe toutefois des exceptions, Ptolémée et Lysimaque, dont on explore l’usage des cicatrices ainsi que ses limites.
La cité grecque entre Aristote et les modernes
Authors: Fröhlich Pierre
Published: June 2023

This paper focuses on a famous passage from Book III of Aristotle’s Politics, which ties the status of citizen and the ability to participate in archè. Some historians have emphasised that such a definition of Greek citizenship had serious limitations. In particular, they have insisted on the part of religion in integrating men and women to citizenship. In front of those interpretative traditions, the paper proposes a return to the text and a new translation. Then it comes back to its potential uses by historians who study connections between archè and participation. Yet it concludes that one just cannot define the Greek citizenship in a single and global way.
Un fantasme monumental : la statue-monde d’Alexandre le Grand
Authors: Azoulay Vincent
Published: June 2023

Selon une riche tradition littéraire, l’architecte Deinocratès aurait proposé à Alexandre le Grand de sculpter le Mont Athos à son image – ce que le roi macédonien aurait refusé. S’il ne fut jamais réalisé, ce projet grandiose condense toute une série de tensions propres à l’époque hellénistique – entre figuration colossale et statuaire à taille humaine, entre Orient et Occident, voire entre hommes et dieux. Assurément, ce fantasme architectural pourrait n’avoir aucune base historique et n’être qu’une invention a posteriori des auteurs anciens, parachevée au IIe siècle av. J.-C. Cependant, s’il s’agit peut-être d’une fiction, celle-ci s’inscrit dans une réflexion sur la pérennité des honneurs, dont les premiers jalons remontent bien à la fin du IVe siècle av. J. ‑C. – à l’époque d’Alexandre ou peu après sa mort. Dès lors, cet article cherche moins à opposer le rêve et la réalité qu’à comprendre les fondements historiques sur lesquels repose l’invention de ce monument imaginaire.

Ce travail porte sur des recherches sur les représentations sociales du Travail de l’enseignant auprès d’étudiants (278 participants) de Première et Dernière année des cours de Pédagogie et d’autres Licences d’une université publique brésilienne. Nous avons utilisé comme instrument de collecte un questionnaire constitué de questions ouvertes et fermées. Les résultats, traités par les logiciels ALCESTE et SPSS, ont montré qu’il n’y a pas de différences étudiants pour une grande partie prétendent enseigner en tant que professeurs tout de suite après avoir terminé leurs études, ont une vision négative de leurs futurs élèves, souffrent peut-être de la représentation pessimiste de la société sur le travail d’enseignant et se considèrent peu capables de changer la mauvaise situation de l’école publique brésilienne. En conclusion, nous développons l’idée qu’il est urgent que les cours de formation des professeurs se préoccupent davantage de la construction de l’identité professionnelle et des perspectives du travail d’enseignant.
Intellektuelle Bescheidenheit
Authors: Wüthrich Hans A.
Published: June 2023

Passende Lösungen für anspruchsvolle Probleme lassen sich nur finden, wenn es gelingt, die Intelligenz im Kollektiv zu nutzen, echte Dialoge zu führen und gemeinsam klüger zu werden. Erforderlich dazu ist eine spezifische Form der Demut, eine sogenannte intellektuelle Bescheidenheit. Ingredienzen dieser unbescheidenen Bescheidenheit sind: Realität als Eigenkonstrukt begreifen und die eigene Weltsicht nicht als Referenz sehen, nicht recht haben müssen und auf die Deutungshoheit verzichten, Unwissen eingestehen und Überzeugtsein nicht mit Wissen verwechseln, sich experimentell annähern und handelnd ins Verstehen kommen, dem Mainstream misstrauen und Dinge ausprobieren, die dem antrainierten Menschenverstand widersprechen. Intellektuelle Bescheidenheit zu wagen, erfordert Mut.

Sanjai Rina is one of the small and medium industries (SMEs) that produces and sells sanjai chips. This study aims to identify aspects that cause rejected production in Sanjai Rina. This study uses the Statistical Process Control (SPC) method with the Failure Mode and Effect Analysis (FMEA) approach. The stages of the research started with problem identification, brainstorming, FMEA calculations, and recommendations for improvement. Identifying problems using the required to-quality method and IPO diagrams followed by brainstorming to identify the existing problems using fishbone diagrams in more detail. FMEA calculations design a questionnaire for RPN FMEA calculations by considering severity, occurrence, and detection weighting. The resulting rejected products are broken sanjai, burnt sanjai, and non-crispy sanjai chips. The research results found that the highest cause for each cause of rejection was the same, namely the potential due to low worker skill failure with an RPN FMEA value of 409.6. Several solutions can be proposed from this research, while the priority solutions are making work SOPs and making work instructions for the frying section.

The person from the beginning of his life struggles to survive, he learns from everything around him to integrate it into his environment, learning has no end, education extends all stages of their human development, however, he can't do it alone, He has to search a the individuals around him, both from his family and social context. Formal education is a human aspiration, guided and protected by agreements and conventions of global and local scope, which has become a right to education. An investigation was developed in two phases: first, a bibliographical documentary research to recover text related to the right to education and in a second phase, an online questionnaire was applied to higher education students of the Universidad Autónoma Indígena de México (UAIM) to know the experiences of the student of what he has lived in each of the stages of his school way (elementary, middle school, high school and college), their motivations to study at the UAIM and their point of view on the right to education. Subsequently, through interpretive research, explain the findings obtained contrasted with the revised documentation. Referring particularly to the right to education in the Mexican historical context, we have found various intervention topics such as: the legal framework that supports said right, educational inequalities at the levels of basic education, half education higher and higher education; indigenous education; educational inequality caused by the COVID-19 pandemic; unofficial basic education; and higher education at UAIM. The indicators of the right to education made it possible to found out the fulfillment and commitment of the UAIM. and the confinement mechanisms due to COVID-19 cause new forms of inequality to emerge.

In Chihuahua, Mexico, the cultivation of vines (Vitis vinifera L.) Tempranillo variety was established, in order to have options for growing grapes for wine, since it has climates suitable for the cultivation of this species and this allows obtaining crops that meet with the specifications for vinification; where the objective of the present study was to determine the technological maturity and characterize the phenolic composition of grapes of the Tempranillo variety, to specify the harvest date (harvest), weight of berries and their components in Chihuahua, Mexico; made in 2016, in three vineyards: one located in the municipality of Aldama (Pasado Meridiano) and two in the municipality of Cuauhtémoc (FACIATEC and Hacienda Bustillos). The experimental design was randomized complete blocks; the samplings were carried out weekly, from the beginning of the veraison (ripening) until the harvest; Chemical analyzes were carried out: soluble solids (°Brix), total titratable acidity (ATT) and pH, to monitor technological maturity; In addition, the total polyphenol index (phenolic maturation) was quantified. The optimum result in berry quality for vinification was presented by the vineyards located in the municipality of Cuauhtémoc (FACIATEC) and H. Bustillos; however, the berries from the Pasado Meridiano vineyard showed a very early maturation, and in the quantification of total polyphenols it is lower compared to the rest of the vineyards, thus reflecting a low color intensity.
