The annual dynamics of (1) chloroform-extractable substances (CES) and petroleum hydrocarbons (PH) in riverside fluvial sediments, in the bottom sediments of the mixing zone of river and sea waters, and in the bottom sediments of the marine area, and (2) the abundance of hydrocarbon-oxidizing (HOB) and heterotrophic (HB) bacterial groups in the bottom sediments of the marine area and riverside sediments is analysed. The maximal content of CES was found in the marine area (450±17.5 mg/100 g), and the minimal one - in the river part (127.6±10.9 mg/100 g), in the mixing zone of river and sea waters - 370±37.9 mg/100 g. The average concentrations of PH are distributed similarly to the concentrations of CES: the maximal values (127.5±10.9 mg/100 g) are detected in marine ground, the values for the sediments of the mixing zone are slightly lower (103.1±9.4 mg/100 g), and the minimal values (54.8±23.9 mg/100 g) are detected in river sediments. The physicochemical characteristics of bottom and coastal sediments are presented. The abundance of HB in the bottom sediments of the marine area varied from 7.5•103 to 2.5•106 cells/g, respectively, and from 9.5•103 to 9.5•108 cells/g in the river area. There was no seasonal variability in the abundance of HB at both areas. Hydrocarbon-oxidizing bacteria were registered in 100 % of the samples of bottom and riverside sediments of the designated water areas. The abundance of HOB varied from 25 to 2.5•104 cells/g in the marine zone and from 25 to 4.5•103 cells/g in the river zone. The maximal values of HOB abundance in the riverside sediments were recorded during the flood period (February-April).

Authors: TROPIN E S. , GONGOLA M I. , NEMUDRY A P.
Published: August 2024

A mathematical model of the flow of hydrogen from gas mixtures through the walls of capillary tubes made of metallic nickel has been developed, taking into account the inhomogeneity of the partial pressure of hydrogen along a long tube, as well as temperature nonuniformity in different regions of the tube. Using the model and relying on experimental data, the kinetic parameters of hydrogen transport were calculated within the temperature range of 600-850 °С and the hydrogen partial pressure range of 0.3-0.8 atm. The model can be used in the design of membrane modules for hydrogen separation from gas mixtures to calculate the length of individual membranes, their number, and the optimal flow rate of the hydrogen-containing gas mixture through the membrane.
Development of Aesthetic Perception in 4-8-Year-Old Children Using the Method of Observing Artworks
Authors: Sidabrienė Jurga
Published: August 2024

In the research on cultural education activities in European countries (2021), questions are raised about whether digital development and improved children’s access to cultural resources inherently contribute to a more successful development of children’s aesthetic perception. International studies on children’s aesthetic education (Savva, Acer, Beck, Kim, Denac, Bergman, Yi-Huang Shih Ching, etc.) highlight children’s participation in observing works of art as a condition for promoting children’s aesthetic perception. However, attention is drawn to the insufficient art competencies of early childhood educators in the context of exploring works of art. This article aims to demonstrate that the method of observing works of art can be an effective means of fostering children‘s aesthetic perception, provided that educators seek to acquire sufficient knowledge and competencies for the application of the art observation method. For this purpose, a literature analysis method was chosen for the study: based on insights provided by foreign and Lithuanian researchers, the article presents the structure of the art observation/research method, distinguishing visual and aesthetic components of the artwork. It also introduces recommended artists from foreign studies, identifies the most effective ways and forms of presenting artworks for the development of children’s aesthetic perception, and reviews the contexts and practices of applying the art observation method in international studies for children aged 4–8.

The article discusses the topic of mentoring within the education system as well as analyzes the experience of the project “Schoolchildren for Schoolchildren” carried out at St. Joseph’s school as part of the project “Optimization of the network of higher schools and improvement of the quality of studies by connecting Šiauliai University to Vilnius University“.A mentorship model was developed and implemented in the school, followed by senior schoolchildren assisting primary school pupils with learning difficulties. Mentoring activities were evaluated by the research consisting of a questionnaire, a focus group method, as well as notes recording experiences. Mentors, parents and teachers of primary school pupils participated in the research.During the project, the mentors tried themselves in a new activity, developing competences of dutifulness, responsibility, teaching others, communication and collaboration. Despite the difficulties arisen and motivation decrease during the process, this activity instilled them with satisfaction and positive emotions, as they felt having spent their time meaningfully, developing the teaching and communication skills of juniors, as well as strengthening and fostering relationships with peer mentors. The research found that primary school pupils benefited from homework help from mentors - some of them improved learning motivation, skills and performance, as well as communication skills.The project demonstrated that the mentoring model is also a way to develop schoolchildren’s leadership, strengthen the relationships inside the school community; apart from that, it contributes to the creation of a culture of solidarity and social capital based on generosity and unconditionality. The model utilized at this school can be further developed and adopted elsewhere, taking into account the proposals of the research participants to publicize the project more, include it in the mentorship program and leisure activities, thus creating conditions for the development of children’s creative leisure time and mutual friendship.
The changing role of a book in the society
Authors: Zinkevičienė Julija
Published: August 2024

During different periods, a book played a different role in the life of society, depending on social, economic, and cultural conditions.
The article seeks to analyze the role of a book as a document in several aspects: the book as a document, changes in its structure and carrier, changes in its functions during different periods, and the advantages and shortcomings of printed and electronic books. The place of a book within the system of mass media and its future is also discussed.
A document, as a source of knowledge, is a unity of content and form. Research has mainly directed attention to the most important forms of documents. A book became the main object of research not because it is a printed item, but because it has dominated the system of documentary communication.
The development of science and technology gave birth to new carriers of information and changed the traditional information environment into a virtual one, along with the material form of a document. The document consists of three components: information, a carrier, and technology for recording the information on the carrier (including technology for document identification). Two of these components may differ: the material form turns into a digital form, which exists in a virtual environment. The structure of the document changes from linear to digital. The social and economic environment is characterized by lowered production costs. Quicker and simpler technological processes attract a significant part of society.
For a long time, the term "book" was used generally to denote documents. However, a book has its own specific features and differs from other documents. The book is characterized by two aspects: content and form. Content includes the essence of a book, such as ideas and thoughts. The form is the material environment that transfers and preserves information. A book is one of the most popular and oldest types of documents and has a unique place in society and history.
It is claimed that the role of books in human life diminishes; however, a book is something continuous that stays with a person from childhood to old age. Some years ago, a book was revived and prepared for a new life. Its form and existence will depend on the social, economic, and cultural environment. The market will also influence how electronic and printed books will continue to exist.
A book remains a guarantor of stability, cultural value, historical heritage, and its form, structure, functions, and role will become clearer in the future.

Solanum tuberosum (potato plant) vegetable crop is used worldwide in various industries like food & beverage industries and pharmaceutical industries. Its potential improved agricultural production can be helpful to combat the global hunger index of many underdeveloped and developing countries. But production is getting hampered due to various reasons such as post-harvest losses, early ripening and moreover because of few bacterial and fungal diseases such Bacterial wilt, Septoria leaf spot, Late blight, Early blight, Common scab, Black scurf/ canker caused by Clavibacter michiganensis. Currently there is a growing interest in the study of nano dispersions due to its bioavailability and biocompatibility that found to report which destabilized the lipid membrane of the pathogenic microbes due to their potent antimicrobial activity. As well as, their nano sized droplets will likely increase transport efficiency of any kind of loaded chemical or biological molecules to the targeted sites which also imparted antimicrobial resistance to crop plant especially potato plants. Managing the plant pathogenesis through various green and sustainable herbal nanopreparations can be observed satisfactory for the environmental concerns and cost effectiveness especially for autumn winter tomato which face the decrease in production either early flowing and fruiting period or post-harvest loss due to attack of fungal and bacterial pathogens.

Selective solid phase extraction of folic acid from tomato as a biological source with a magnetic molecularly imprinted polymer measured by fluorescence spectroscopy
Authors: Tohidi M.S. , Mirmohammadi M. , Kolahdoozan M.
Published: August 2024

A novel magnetic molecular-imprinted polymer (MMIP) was used to selectively extract folic acid directly from real samples. Folic acid was used as template molecule, Fe3O4/SiO2-3-triethoxysilyl-propyl-acrylamide as functional monomer, azobisisobutyronitrile as initiation, ethylene glycol dimethacrylate as crosslinker agent, and acrylamide as the secondary monomer in a mixed ethanol-water solvent. The effect of different parameters on the extraction efficiency was studied, and the optimum conditions were established as follows: the concentrations of crosslinking and template were fixed at 0.05 and 0.06 g, absorption percentage was 96.5, pH was adjusted to 8, and extraction time was 8 h with a temperature of 25 °C. By examining the effect of pH, we tried to investigate the effect of the amide groups that present in MMIP and its intermolecular hydrogen interaction with folic acid. After optimising the effective parameters in polymer synthesis and adsorption rate, a magnetic imprinting dispersive solid-phase extraction method combined with fluorescence spectrophotometry at λem = 367 nm (MMIP-DSPE-FL) was constructed for sensitive determination of folic acid in tomato samples. The limit of quantification (LOQ) and limit of detection (LOD) values were 30.00 ± 0.01 μg L−1 and 10.00 ± 0.03 μg L−1, respectively, after the MMIP-DSPE preconcentration. Three tomato samples were analysed to give recoveries in the range of 80.2–81.6%, with relative standard deviation values below 0.6% (n = 3). The prepared MMIP-DSPE showed high selectivity toward folic acid, which could be used six times without changing adsorption capacity. The adsorption isotherm of the folic acid-imprinted polymer pursued the Langmuir model (RL = 0.029), and the kinetics model followed pseudo-first-order (R2 = 0.9974).

Objective

Corpus luteum is a transient structure which plays an important role by producing crucial hormones required for conception and pregnancy maintenance. The objective of this study was to compare grey scale morphological appearances and Doppler indices of corpus luteum in normal and abnormal pregnancies during first trimester.

Methodology

A comparative study was carried out after getting approval from Institutional Research Ethical Committee. A total of 156 pregnant women, 78 with normal and abnormal pregnancies each, with gestational age between 5 and 8 weeks were included in the study. Out of the abnormal pregnancies 52 (66.66%) were cases of threatened while 26 (33.33%) had missed abortion. Transvaginal ultrasound was used to assess the corpus luteum on gray scale and Doppler ultrasound.

Results

There was no significant difference between gray-scale sonographic appearances of normal and cases of missed and threatened abortion on Chi-square test. However, PI, RI and SD ratio showed significant difference between normal and cases of missed and threatened abortion on Kruskal- Wallis test.

Conclusion

Doppler indices recorded from the vasculature of corpus luteum can serve as an important indicator of the pregnancy outcome during early pregnancy.
Defects and doping in ultra-wide band gap (Al,Ga)N and β-(Al,Ga)2O3 alloys
Authors: Tuomisto Filip
Published: August 2024

Si is the n-type dopant of choice for GaN and β-Ga2O3. However, in (Al,Ga)N and β-(Al,Ga)2O3 alloys, when the Al content is increased, the n-type conductivity produced by the added Si impurities is efficiently compensated. The experimentally determined critical Al fractions are about 70% for the (Al,Ga)N alloys and as low as 25% for the β-(Al,Ga)2O3 alloys. AlN and Al2O3 are well known to be poorly n-type dopable even with Si, but the detailed compensation mechanisms in the alloys are not necessarily the same as in the compounds. This short review discusses recent research in Si-doped (Al,Ga)N and β-(Al,Ga)2O3 alloys in the light of the compensation phenomena caused by Si DX center and cation vacancy formation.

RESUMO Neste artigo, examinarei “As confissões da carne”, de Foucault, como propósito de compreender primeiramente por que encontramos no cristianismo e especialmente na obra de Agostinho a mais avançada tecnologia matrimonial como uma instituição de internação do desejo e fundamental da sociedade. Em seguida, a partir da tese de que “As confissões da carne” podem ser apreciadas como um outro O Anti-Édipo, proporei que elas não são somente uma obra antipsicanalítica, mas também antiestruturalista, com o reconhecimento de que as sociedades judaico-cristãs não são reguladas pela parentalidade deduzida da proibição do incesto e sim por uma conjugalidade anterior à parentalidade e metafisicamente pré-incestuosa. Por fim, ensaiarei um experimento interpretativo de “As confissões da carne” para reconsiderar fundações teológicas do homem, em cotejo com o pseudo O Anti-Narciso, de Viveiros de Castro.
Analysis of citrus production efficiency and inter-provincial variability in China under the constraints of non-point source pollution
Authors: LIN Chun-tao , Wang Mingxin , SU Bao-cai
Published: August 2024

ABSTRACT: Globally, China is one of the primary citrus producers. This study provided a theoretical reference for sustainable production in the citrus industry in China by measuring citrus production efficiency under non-point source pollution and analyzing inter-provincial variability. In this study, non-radio logical and non-angled data envelopment analysis models were used in seven provinces during 2006-2018 based on non-desired outputs. The temporal and spatial characteristics were analyzed to determine the factors that cause efficiency losses. Results indicated that the citrus production efficiency had a general w-type trend with high inter-provincial variability, where the highest and lowest production efficiencies occurred in Hubei Province and Guangdong Province, respectively. In the past four years, a redundancy in labor and fertilizer inputs was also observed in Guangdong and Fujian, respectively. The shrinkable proportion of each factor input in the seven provinces was zero. An increase in citrus yield per hectare was recorded, in which the highest was in Guangdong. In each province, high emissions of total nitrogen and phosphorus generally caused the decrease in citrus production efficiency.

ABSTRACT: Bracken ferns (Pteridium spp.) have been associated with intoxication in cattle and is the cause of bovine enzootic hematuria (BEH) characterized by intermittent hematuria, anemia, and poor body condition. Acute phase proteins have not previously been investigated in detail in BEH. Thus, this investigation determined serum concentrations of haptoglobin, selected hematological (complete blood count and fibrinogen), biochemical (total serum protein, albumin, urea, creatinine, aspartate aminotransferase, gamma glutamyl transferase, and creatine kinase), and urinary analytes, in 50 Nelore cows from farms with history of natural bracken fern chronic ingestion in the southern region of Brazil. Twenty-nine cows had macrohematuria and 21 microhematuria. From the 29 cows with macrohematuria, 13 had a countless number of erythrocytes per high power macroscopic field and anemia. All cows had dipstick proteinuria. Median haptoglobin concentrations were elevated for 47 BEH cows with a 3.9-fold increase, suggesting a chronic inflammatory response while the number of total leukocytes and segmented neutrophils were above the reference intervals for 14 cows. Besides inflammation, there is a hypothesis that bracken fern could cause hemolysis in the circulation. Therefore, there could be a larger acute phase reaction but much of the haptoglobin was being removed as it was being produced. In our study, increases in haptoglobin, creatine kinase, hyperglobulinemia and anemia were found in cows with BEH, contributing to the understanding of the chronic inflammatory response which could be associated with neoplastic lesions in the urinary bladder caused by long-term and repeated ingestion of Pteridium species.

Abstract Cisplatin is an antineoplastic medicine used in the treatment for various types of cancer. Among its side effects is ototoxicity, which may result in a bilateral and irreversible hearing loss. The ototoxic effect in the pediatric population has a bigger impact as it compromises language acquisition. The discovery of drugs with otoprotective effects and the optimal way to administer them have become significant challenges in minimizing the impact of cisplatin regarding auditory function. The objective was to understand otoprotective drugs and their relevance in the preventive treatment to cisplatin-induced ototoxicity in childhood. An integrative review was conducted by consulting databases including PubMed, Bireme, MedLine, LILACS, SciELO, and ClinicalTrials.gov. The search strategy was performed by crossing descriptors (DeCS and MeSH) and free terms. Studies published in English, Spanish, and Portuguese were selected, with no publication year restrictions. Subsequently, articles were selected according to inclusion and exclusion criteria. A total of 736 articles were found in PubMed, 431 in Bireme, 425 in MedLine, 6 in LILACS, 0 in SciELO, and 4 in ClinicalTrials.gov. After document analysis, 12 articles were selected for full analysis. Evidence was found for 8 substances with potential otoprotective effects when used with cisplatin, which tend to minimize the impact of cisplatin regarding auditory function. The substances found were: Amifostine, Dexamethasone, Genistein, Ginkgo Biloba, Lycopene, N-acetylcysteine, Polydatin also Sodium Thiosulfate. In general, these drugs are applied before, during, or after cisplatin infusion, depending on the chosen drug, via intravenous, oral, or transtympanic injections, acting as antioxidant therapy. The biochemical effects of these substances are relevant to their potential otoprotective properties, including the inactivation of oxygen free radicals and electrophilic platinum species. The use of these substances can reduce ototoxicity, decreasing cisplatin-induced hearing loss and improving the confort of life, especially for children.

Abstract A total of 381 specimens of the tilapia Oreochromis mossambicus collected monthly from May 2017 to May 2018 in the Laguna de Los Patos, Cumaná, Venezuela, to evaluate reproductive parameters of this non-native species. Significant differences were found in relation to average height and weight between males and females, with the highest values in males. The sex ratio was 1:1.5 (males:females), which deviates significantly from the expected 1:1 ratio. The mean length of sexual maturity (Lm50) was 18.0 cm in females and 20.1 cm in males, reflecting that females mature at smaller sizes than males. The monthly variations of the gonadosomatic index (GSI) and the stages of sexual maturity show two reproductive peaks during the study, in October 2017 and April 2018, coinciding with the rainy and dry seasons in the region respectively. The condition factor (CF) showed significant differences between months, but not between sexes, with an average of 1.87 in females and 1.84 in males. The average absolute fecundity was 921 ± 604.6 eggs per fish, with a relative fecundity of 8.36 ± 3.09 eggs per gram of fish. Differences in oocyte size in mature females confirm that the species can spawn repeatedly over a period, which is considered an important factor for the establishment of tilapia in non-native environments.

Resumo Objetivos: estimar a correlação entre peso ao nascer, amamentação e índice de massa corporalem crianças de seis anos de Palhoça/SC, Brasil. Métodos: estudo transversal envolvendo 502 crianças. Os dados foram coletados por entrevistas com mães nos domicílios e avaliação antropométrica nas escolas. O índice de massa corporalatual da criançafoi a variável dependente. As variáveis independentes foram peso ao nascer, tempo de amamentação, tempo de amamentação exclusiva. As correlações entre as variáveis foram estimadas pelo coeficiente de correlação de Pearson e respectivos coeficientes de determinação. Foi realizada análise de regressão linear multivariada para observação da independência entre as variáveis. Resultados: o peso ao nascer e o índice de massa corporal aos seis anos mostraram correlação positiva estatisticamente significativa (r= 0,115; p= 0,008). O tempo de amamentação não se mostrou correlacionado (r= -0,018; p= 0,683). Já o tempo de amamentação exclusiva mostrou correlação negativa estatisticamente significativa (r= -0,103; p= 0,018). Entretanto, a análise de regressão linear multivarida mostrou correlação positiva independente e significativa somente entre o peso ao nascer e o índice de massa corporal aos seis anos de idade (r= 0,142; p= 0,003). Conclusão: o maior peso ao nascer correlacionou-se positivamente de forma significativa e independente com o aumento do índice de massa corporal aos seis anos de idade.

Abstract Objectives: to estimate the correlation between birth weight, breastfeeding, and body mass index in six-year-old children in the city of Palhoça/SC, Brazil. Methods: a cross-sectional study involving 502 children. Data were collected through interviews with mothers at home and anthropometric assessments at schools. The child’s current body mass index was the dependent variable. The independent variables were birth weight, breastfeeding duration, and exclusive breastfeeding duration. Correlations among variables were estimated using Pearson’s correlation coefficient and respective coefficients of determination. Multiple linear regression analysis was performed to observe the independence among the variables. Results: birth weight and body mass index at six years of age showed a statistically significant positive correlation (r= 0.115; p=0.008). Breastfeeding duration was not correlated (r= -0.018; p=0.683). The duration of exclusive breastfeeding showed a statistically significant negative correlation (r= -0.103; p=0.018). However, multiple linear regression analysis showed an independent and significant positive correlation only between birth weight and body mass index at six years of age (r= 0.142; p= 0.003). Conclusion: higher birth weight was significantly and independently positively correlated with increased body mass index at six years of age.

ABSTRACT Streamflow data from gauging stations are essential for effective water resources management. However, some regions in Brazil lack the necessary data. Hydrological regionalization is an alternative technique for obtaining data such regions. However, not all regions in Brazil have defined hydrological regionalization models, including the state of Goiás and the Brazilian Federal District. The objective of this study was to develop a hydrological regionalization methodology based on the separation of hydrologically homogeneous regions and multiple linear regression, using a Geographic Information System (GIS) program. Historical series data were used to calculate reference flows with 90 or 95% duration over time in the watercourse (Q90 and Q95) and the mean flow (Ǭ). Rain gauge station data were used to calculate the mean annual rainfall in each watershed through spatial interpolation by ordinary kriging. Subsequently, the physiographic characteristics of each watershed were calculated. The hydrologically homogeneous regions were delimited based on these data using cluster analysis, which identified seven hydrologically homogeneous regions in Goiás, two of them belonging to the Federal District. Multiple regression allowed the development of seven regionalization models. Models for regions 1, 3, 4, 5, and 7 showed better performance.

ABSTRACT Soil contamination with toxic metals brings along severe environmental issues. Among these metals, copper (Cu) is harmful to plant development when it reaches high contamination levels in the soil. Thus, identifying species capable of resisting this contamination type helps these sites’ revegetation and decontamination processes. Therefore, the present study aimed to investigate the tolerance of Cedrela fissilis plants to excess Cu through morphophysiological and biochemical variables. C. fissilis seedlings were subjected to five concentrations of Cu (0, 2, 4, 6, and 8 mg L-1). The experimental design was completely randomized, with five treatments and four repetitions. Morphophysiological (number of leaves, shoot height, root length, dry weight, morphological variables of the root system, and leaf area) and biochemical (antioxidant enzymes, lipid peroxidation, hydrogen peroxide concentration, and photosynthetic pigments) traits and Cu accumulated in roots and shoot were evaluated. High concentrations of Cu had a negative effect on the shoot and root dry weight, photosynthetic rate, stomatal conductance, and transpiration rate. Overall, Cu increased the activity of the antioxidant enzymes and lipid peroxidation. Therefore, Cu incidence in the nutrient solution has negatively influenced the biochemical and physiological traits of C. fissilis seedlings to the detriment of their growth. Thus, it was possible to identify sensitive behavior by the investigated species. Because of these features, C. fissilis seedlings can be used as markers for copper-contaminated areas.

RESUMO Objetivo: comparar os níveis de empatia entre estudantes de enfermagem em diferentes estágios da graduação, considerando gênero e idade. Método: estudo conduzido na Faculdade Israelita de Ciências da Saúde Albert Einstein, com abordagem quantitativa, descritiva, comparativa e transversal. A amostra incluiu 169 alunos dos quatro anos de graduação em Enfermagem. Utilizou-se um questionário sociodemográfico para coletar informações no período de agosto de 2020 a abril de 2022 e a Escala Multidimensional de Reatividade Interpessoal para mensurar empatia. As relações entre empatia e variáveis independentes foram analisadas, utilizando modelos lineares e apresentados com médias estimadas, intervalos de confiança e valores-p, com nível de significância de 5%. Resultados: a comparação dos níveis de empatia em diferentes períodos da graduação não revelou relações significativas com o ano de graduação. No entanto, o menor escore nas três subescalas ocorreu no quarto ano. Ao analisar a relação entre anos de graduação e gênero, nenhuma subescala apresentou diferenças significativas. Ao separar por ano de graduação, a diferença significativa na subescala Consideração Empática surgiu no segundo ano, com escores mais altos para o gênero feminino. Conclusão: o estudo destaca a importância contínua do ensino de empatia na formação em enfermagem. Assim, a utilização da Escala Multidimensional de Reatividade Interpessoal se mostra valiosa para avaliar intervenções e oferecer subsídios para ajustes nas estratégias educacionais. O compromisso com o aprimoramento da empatia ao longo da formação e prática profissional é essencial para garantir uma assistência de saúde verdadeiramente centrada no paciente.
Abdelmalek Sayad Ma dette. Son inquiétude épistémologique
Authors: Laacher Smaïn
Published: August 2024

Résumé Abdelmalek Sayad a indéniablement contribué à une plus grande intelligence du fait migratoire en tenant ensemble histoire, sociologie et anthropologie. Cela signifiait qu’il était scientifiquement inenvisageable, pour lui, de penser séparément pays producteurs d’exil et pays d’accueil des exilés. Etudier l’immigration et les immigrés, qui sont-là deux catégories différentes, ne peut trouver ses (meilleures) conditions d’accomplissement que si l’on réfléchit, dans le même acte, sur ce que l’ont fait lorsqu’on examine, en pratique et en théorie, des populations dépossédées d’une parole publique ; autrement dit, dessaisies, en partie par le droit, d’une parole politique. La sociologie d’Abdelmalek Sayad a ouvert des perspectives épistémologiques inédites. Cette singularité méthodologique se déployait aussi dans sa pratique réflexive. Tous ses textes le montrent, sous une forme ou sous une autre.
