Published: April 2024

In 2021, a study was conducted in the Denizli region of Türkiye to investigate the phylogenetic relationship and presence of alfalfa mosaic alfamovirus (AMV) infecting pepper plants exhibiting viral disease symptoms. A total of 57 samples were collected, of which twenty-four tested positive for AMV with reverse transcriptase polymerase chain reaction (RT-PCR) assays. Samples from pepper plants displaying virus symptoms gave positive bands on the agarose gel, while healthy plants yielded negative results. One of the positive samples was randomly selected, cloned and sequenced. This sequence of the Denizli AMV isolate (753 bp) was recorded in the GenBank database with accession number OQ845956. The nucleotide sequence showed a high nucleotide consensus of 97%-99% compared with the nucleotide sequences of the same variants from different origins in GenBank. According to the phylogenetic tree generated through the Neighbour Joining (NJ) method, this AMV isolate belongs to the same group as Iranian isolates from various of hosts. Furthermore, in silico docking analysis of the coat protein (CP) of the AMV isolate and promising 12 essential oil compounds was performed to enable potential antiviral drug development. Docking study showed that eucalyptol, eugenol and carvacrol can make important contributions to the advancement of drug-based strategies for the managing of plant viruses by interacting with the virus coat protein of high binding energies, -5.3, -5.2 and -5.0 kcal mol-1, respectively. Although the presence of AMV in Denizli province has been reported previously, this study reports the phylogenetic relationships and docking analysis of the new AMV isolate in pepper crops.

Mistletoe (Viscum album L.), a semi-parasitic medicinal plant, continues to be of interest, due to its phytochemical composition. The leaves of mistletoe contain phenols, which have a variety of biological effects. The main goal was to characterize the mistletoe that parasitized Robinia pseudoacacia L., (called VAR) in terms of phenolic compounds and to assess the wound healing potential in vitro using the scratch method. Furthermore, the antioxidant capacity was evaluated both by spectrophotometric techniques (DPPH, FRAP, TEAC), as well as by the ability of the mistletoe extract to synthesize green selenium nanoparticles. Among the phenolic acids, dihydroxybenzoic acid is in high level (2.86±0.03 mg/g dw), whereas isorhamnetin-glucuronides dominate the flavonol class (0.593±0.03 mg/g dw). The presence of phenolic compounds in the VAR leaves provides antioxidant capacity. The reducing capacity of VAR extract was demonstrated for the first time by the biosynthesis of nanoselenium particles (NSePs) with a regular, spherical shape and a diameter of around 130 nm. The VAR concentrations of 25-200 µg/mL showed no toxic effect on normal human dermal fibroblasts (NHDF), and the concentration of 100 µg/mL exhibited the best percentage of wound surface closure in vitro (94.08%). The results show that mistletoe is a promising plant because of its phytochemical composition and antioxidant capacity, which can modulate the wound repair process in vitro.

Published: April 2024

Leaf nitrogen content (LNC) is an important index to measure the nitrogen deficiency in cotton. The rapid and accurate monitoring of LNC is of great significance for understanding the growth status of cotton and guiding precise fertilization in the field. At present, the hyperspectral technology monitoring of LNC is very mature, but it is interfered with by external factors such as shadow and soil, and data acquisition is still dependent on manpower. Therefore, on the basis of clarifying the correlation and quantitative relationship between physiological parameters and cotton LNC, the 400-2500 nm spectral curve was simulated based on PROSPECT-5 model. Combined with the measured spectra, the sensitive bands of leaf nitrogen content were screened, and four machine learning algorithms based on the reflectance of the sensitive bands were compared to construct a model for the estimation of LNC in cotton and determine the optimal model. The results show the following: (1) The parameter with the best correlation with nitrogen content was Cab, and the linear relationship was y=0.3942x+12.521, R2=0.81, RMSE=12.87 g/kg. (2) The shuffled frog leaping algorithm (SFLA) and the successive projections algorithm (SPA) were used to screen the relevant bands sensitive to LNC. SFLA selected nine characteristic bands, mainly distributed between 700 and 750 nm. SPA screened seven characteristic bands, mainly distributed between 670 and 760 nm. The characteristic bands of both screening methods were distributed near the red edge. (3) Based on the sensitive bands, the four machine learning algorithms were compared. Among them, the band modeling of SFLA screening under the random forest (RF) algorithm was the best (modeling set R2=0.973, RMSE=1.001 g/kg, rRMSE=3.41%, validation set R2=0.803, RMSE=3.191 g/kg, rRMSE=10.85%). In summary, this study proposes an optimal estimation model of cotton leaf nitrogen content based on the radiative transfer model, which provides a theoretical basis for the dynamic, accurate, and non-destructive monitoring of cotton leaf nitrogen content.

Caper (Capparis spinosa L.) is a medical plant grown in Jordan. Mass harvesting of caper plants from their origin environments caused a reduction of these germplasm. Therefore, an easy and consistent method for clonal proliferation and callus induction was established for this species. C. spinosa L. in vitro culture affected in MS medium provided by 0.5 mg/L BAP gave 5.9 microshoots/explant. Two months later MS medium supplemented with 2.0 mg/L NAA developed a maximum callus induction of 33.1 mm. Ex vitro, in vitro, and callus growth of C. spinosa L. using ethanolic and methanolic extracts were tested for their antimicrobial activity against different species of bacteria and fungi. Both ex-vitro and in vitro plants exhibited similar antimicrobial activity. Maximum ex vitro plant antibacterial activity was (23 mm ± 0.58 inhibition zone) against Staphylococcus epidermidi. In comparison, callus extracts gave the highest antibacterial activity against Bacillus cereus and Escherichia coli. Moreover, caper plant extracts showed different antifungal effects against the tested fungi species. Investigation of the data showed that ex-vitro extract exhibited maximum antifungal activity compared to in vitro plants. Additionally, exposed Bemisia tabaci 4th nymphal instar to C. spinosa L. extracts suffered mortality ranging from 2 to 28%.  In most instances, both ethanolic and methanolic extracts affected the survival of B. tabaci more than the control. The current study confirmed that C. spinosa L. has a wide range of antibacterial, antifungal, and insecticidal activity.
Combining visual interpretation and image segmentation to derive canopy cover index from high resolution satellite imagery in functionally diverse coniferous forests

Published: April 2024

Forest canopy cover is one of the most significant structural parameters of the forest stand that can be estimated using of aerial and satellite remote sensing. Even though sub-pixel analysis can be used to estimate the index on low-resolution imagery, high-resolution imagery provides more accurate details on forest canopy variability for ecological and forestry applications. However, the high variability of the images demands a more advanced approach to canopy cover measurement than the visual interpretation of single images or stereo pairs. These traditional methods are inefficient and limited in providing a comprehensive and accurate canopy cover assessment. An improvement of the method could involve classifying high spatial resolution images, separating and extracting the areas corresponding to canopy gaps, and generating canopy cover maps. This study offers valuable insights and reveals key differences between three methods for estimating canopy cover: ground measurements, visual photo interpretation and automatic extraction from classified images using pixel and object-based methods. The texture analysis approach was used for separating the “shadow” objects corresponding to gaps in the canopy from the shades cast on the lower trees. The sample plot-based visual interpretation of the images revealed comparable results between ground and satellite image canopy cover values (correlation coefficient of 0.74 for all plots), with lower correlations (r = 0.39) for uneven-aged stands. The results encourage the use of the texture analysis method, with satisfying accuracy (forest canopy cover differences of maximum 0.06 between ground, photo interpreted and extracted datasets). The method could be further integrated with complementary data like LIDAR or hyperspectral images.

Climate change in the Mediterranean areas is increasing problems on droughts, water availability and salinization of irrigation water. These are probably some of the most limiting factors on farming, especially in vegetables production. Capsicum peppers, one the most valuable vegetables in Spain, are quite sensitive to water deficit and particularly to salinity. The use of rootstocks tolerant to these abiotic stresses could be explored as a short/mid-term solution. In this work, we evaluated the ability as rootstocks of several accessions, together commercial F1 ‘Robusto’ and ‘Oscos’, with the cultivar ‘Herminio’ as scion, under control, drought (30% decrease irrigation) and salinity (5.8 dS m-1) in Campo de Cartagena area (Murcia, Spain). Yield and fruit weight, and water content, ascorbic acid content (AAC) and total phenolics (TP) at the unripe and fully ripe commercial stages were evaluated. Under control conditions, our rootstocks did not provide extra vigour and yield as none showed higher performance than the non-grafted ‘Herminio’ in yield (10 kg m-2) and fruit weight (215 g). However, drought and salinity conditions revealed that some accessions might be useful as rootstocks, providing higher yields and/or fruit size than ‘Herminio’, particularly yield under drought, i.e. 5-7 kg m-2 while ‘Herminio’ only achieved 4 kg m-2, and fruit weight in both stress conditions (i.e. 190-223 g vs 173 g under drought, 187-209 g vs 158 g under salinity). On average, drought increased the levels of antioxidants at both ripening stages, while salinity decreased them, specially AAC. Also, remarkable rootstock × treatment interactions, particularly in phenolics, enabled identifying several rootstocks providing high levels of antioxidants at both ripening stages and under both abiotic stresses, improving those from non-grafted ‘Herminio’.

Published: April 2024

O objetivo deste estudo é analisar a criação discursiva de monstros menstruais na literatura infantojuvenil. Nos valemos do neologismo menstrunormatividade , proposto por Josefin Persdotter (2020) para definir os sistemas discursivos que diferenciam a menstruação normal e saudável, da menstruação anormal e patologizada. Analisamos três obras que abordam a menstruação e a constituição discursiva de monstros menstruais, como aquelas que se desviam das menstruações . Descobri quatro discursos: o imperativo de menstruar e tornar-se mulher; a menstruação como um estado alterado da normalidade; a menstruação como um encontro com a “natureza selvagem feminina”; a menstruação como morte. As narrativas ensinam que a insurgência aos sistemas normativos da menstruação resulta na produção de subjetividades consideradas alteradas.

Authors: Korkmaz Abdul Vahap , Hacifazlioğlu Hasan
Published: March 2024

In this study, the use of meta-schist as an alternative to sand–clay in preparing cement raw mixtures was investigated for the first time. To produce the highest quality Portland cement clinker by examining the mineral and chemical properties of meta-schists, two different raw meal samples were prepared, utilising conventional cement clay as a baseline sample ((PC)Ref) and the other with meta-schist ((PC)MSC). The effects of both raw mixtures on burnability tests and reactivity were evaluated based on the unreacted lime content in samples after they had been sintered at 1200, 1300, 1350, 1400 and 1450°C. The porosity amount, distribution, grain structure of silicate phase crystals, and equivalent crystal diameters and amounts of meta-schist clinker phases (C3S, C2S, C3A and C4AF) examined by polarising optical microscope showed that they are suitable for the production of PC. The hydration products of the cement mortars were determined by scanning electron microscopy and energy-dispersive X-ray analysis at 2, 7 and 28 days. In addition, the compressive strength test results of (PC)MSC and (PC)Ref mortars after 28 days of curing ranged between 57 and 55.5 MPa, and the cement produced was classified as CEM I 42.5R.

Aim: Knowledge about the change in the frequency and characteristics of medical sharps injuries during the Coronavirus Disease–2019 (COVID-19) pandemic is very limited. This study aimed to compare the characteristics of medical sharps injuries experienced by healthcare staff before and during the COVID-19 pandemic. Material and Method: A total of 304 cases of medical sharps injuries suffered by hospital staff in our hospital between 2014 and 2022 were included in the study. Data regarding these accidents were obtained from accident files in the hospital archive. Results: The mean age of the staff exposed to the accident was 30.2±10.7 (range: 15-50) years, and 227 (74.7%) were women. During the pandemic, a 34.6% decrease was detected in the annual mean number of medical sharps injuries compared to before the pandemic. In cases during the pandemic, the annual mean rate of interns who had an accident decreased significantly compared to before the pandemic (43.7% vs. 18.8%), while the mean rate of nurses increased significantly (31.9% vs. 53.2%)(p<0.001), and the annual mean needle tip rate decreased significantly (83.0% vs. 68.0%)(p=0.035). Conclusion: The findings of the present study showed that there was a significant decrease in the number of medical sharps accidents during the pandemic compared to the pre-pandemic period, that the rate of nurses who were exposed to accidents increased significantly during this period, that there was a significant decrease in the rate of needle stick-related accidents, that there was a significant decrease in the accident rate in surgical wards and a significant increase in intensive care units.

Published: March 2024

Objective: To investigate the potential relation between dynamic thiol homeostasis and blood transfusion in the pediatric intensive care unit. Methods: Blood samples were collected from pediatric intensive care patients before and after erythrocyte suspension transfusion and from donor blood additionally to measure thiol levels. The study involved 30 patients, including nine females, and a total of 90 blood samples from patients and donors were analyzed. Results: Prior to transfusion, Total Thiol (TT) and Native Thiol (NT) were 414.77 ± 156.14 (μmol/L) and 272.63 ± 115.75 (μmol/L), respectively, and post-transfusion, they were found to decrease to 398.07 ± 187.38 (μmol/L) and 258.97 ± 136.2 (μmol/L), respectively. However, no statistically significant difference was observed between pre- and post-transfusion values. In post-transfusion blood samples, there was a significant increase in Disulfide/TT and Disulfide/NT ratios, indicating an increase in oxidation (34.79 ± 92.34 and 51.89 ± 68.51, respectively), yet no statistical difference was noted. Conclusion: Transfusions administered in the Pediatric Intensive Care Unit were associated with a decrease in total and native thiol levels, indicative of increased oxidative stress, despite the lack of statistically significant differences. To mitigate the potential negative impact on patients with high oxidative properties after transfusions, strengthening the antioxidant defense system is recommended. Research should be planned to develop suitable strategies for enhancing the antioxidant defense system and ensuring patients' resilience to this condition.

Published: April 2024

Abstract— Creating interest and involvement of engineering students into the domain specific research work is indispensable for the future technology developments. Original intellectual and creative contribution through experimentation to the discipline can bring new developments significant for societal reforms. This paper presents an effort to nurture research interest among postgraduate students of Biomedical Engineering. In order to nurture a research attitude, a Lab component for the course Biomedical Image Analysis was modified with practical reflection-based learning style. The impact analysis of this exercise is studied objectively. The newly designed Lab component included more practice-based learning, demanding additional time from students and teacher, for the discussion and reflection-based learning. Assessing students on the basis of critical thinking, focused efforts and the right approach in devising the solution for real-life problems played a critical role in this pedagogy. The impact of this exercise on students learning is analyzed by comparing course outcomes and program outcomes attainment for two batches with batch size 14 and 16 respectively. The assessment was based onrubrics devised for various phases. The course outcomes were improved by 6 to 12% for the experimental Batch. This is also reflected in increase in PO attainment in the same proportion. Particularly, attainment of course outcomes related to handling complex real-life problem and to develop solution showed considerable improvement. The results revealed individual student's ability in implementing and analyzing the open-ended experiment. The major conclusion from this educational experimental work is that the conceptual, practical, and interpretational skills necessary for research can be inculcated by devising innovative pedagogy. This work also reports positive sideways of this practice and the difficulties faced during the entire exercise.

Abstract : The authors carried out a review study on the pedagogy for teaching communication skills (CS) in engineering higher education institutions with a view to firstly present the trend on the instructional pedagogical approaches used in an engineering classroom and secondly, to show the impact of these approaches on learners' development of CS. In order to address the research questions, we adopted 'Systematic Literature Review' as a research methodology and reviewed empirical research studies published between the year 2001 and 2021 exploring electronic database. Having followed the review protocols, we finally selected 26 research articles for a detailed analysis and synthesis. In regard with number of publications, the trends placed the USA at the top position which was followed by India. Overall, we found a lack of experimental research, subsequently a lack of evidence-based teaching practice, in the domain of pedagogy for developing CS leading to the assumption of still prevalent conventional lecture method of teaching in the CS classroom which is further held responsible for poor CS among engineering graduates. The teaching trend indicates that engineering institutions across nations are increasingly becoming aware of evidenced-based teaching approaches and are adopting innovative, learner-centered methods blended with ICT tools to facilitate the process of developing CS, along with other generic skills which has positive impact on learners' development of skills and attributes. The findings have implications for both; research and classroom teaching. Keywords : communication skills; engineering education; instructional pedagogy; systematic literature review.
Neurophenomenology and Neuroepistemology Approaches to Integrating Constructivist, Perennialist, and Universalist Perspectives on Mystical Experiences
Authors: Winkelman Michael James
Published: March 2024

Differences among constructivist, perennialist, and universalist perspectives on mystical experiences are bridged with neurophenomenology and neuroepistemology perspectives that illustrate constructivist and deconditioning processes and universal innate experiences. These approaches show that phenomenal similarities and differences in the features of meditative experiences are related to specific brain functions and processes. This illustrates that recurrent forms of mystical consciousness involve the activation or suspension of specific brain functions and their forms of knowing. Meditators’ deliberate modifications of brain processes engage constructivist and deconditioning processes that provide access to intrinsic states understood as mystical experiences. Deconditioning of habitual cognitive processes through meditation changes habitual attention and cognition, permitting access to preconceptual awareness and normally unconscious intrinsic mental processes. Different mystical experiences involve changes in specific neurologically mediated forms of self that provide the basis for universal forms of mystical experience. Neuroepistemological perspectives on qualia of meditative states and their relations to mental processes and brain features provide a framework for understanding recurrent forms of mystical experiences as natural brain states.

DOI: 10.17014/ijog.vol1no1.20062aGeologically, Bandung Basin and the surrounding area comprise volcanic rocks; therefore, originally the geological resources, such as energy, environmental geology and mineral were generated from past volcanic activities. Energy resources having been utilized or in the exploration stage are water energy (Saguling Electrical Hydro Power) and geothermal energy (Darajat, Kamojang, Wayang-Windu and Patuha Geothermal Fields). Potency of hydrocarbon energy is considered due to the presence of Tertiary sedimentary rocks under Bandung volcanic rocks. Environmental resources include water, soil, land, and natural panorama that mostly are already used for living, tourism, industry etc. Mineral resources cover metals and non metals. Mineral explorations, particularly for gold, have been conducted in the southern Bandung area. Recently, Center for Geological Survey itself has found a new mineral resource in the northern Bandung, i.e. Cupunagara Village, Cisalak Sub-Regency, Subang Regency - West Jawa.

DOI: 10.17014/ijog.v4i4.87The Yogyakarta earthquake of 27 May 2006 occurred at 05:54 WIB with magnitude of 6.4 Mw. It shaked the region of Bantul, Yogyakarta, Sleman and Klaten for about 60 seconds. A week after the earthquake, i.e. 4-8 June 2006, a GPS survey was conducted on 48 GPS points belonging to the 2nd order national cadastral control network located in the earthquake affected region. The 2nd survey was conducted on 21-26 January 2008. The surveys were conducted using 14 dual-frequency geodetic type receivers and the Bernese 5.0 scientific software was used for data processing. The results of GPS surveys show that horizontal components of the co-seismic deformation of earthquake are generally about 10-15 cm or smaller. The GPS-derived displacement vectors and depths of aftershocks suggested the existence of left-lateral fault, with strike and dip angles of about 48o and 89o, located at about 5-10 km east of Opak Fault which is usually drawn along the Opak River. GPS surveys also estimate that horizontal components of the post-seismic deformation of Yogyakarta earthquake are about 0.3 to 9.1 cm between June 2006 and June 2008. While the co-seismic deformation shows the sinistral displacement, the post-seismic deformation indicates the dextral displacement of the eastern region of Opak Fault (Gunung Kidul area) which is relative to a more stable western region.

DOI: 10.17014/ijog.v7i1.132Rajabasa Volcano (± 1281 m) and Lampung Tuff, located in the South Lampung Regency, is the main point in order to understand the evolution of Quaternary volcanism in the area. A remote sensing analysis and field geologic work are the methods of the study. The volcanism began with the construction period of the Pre-Rajabasa composite cone which was followed by the destruction period of the cone to form the Pre-Rajabasa Caldera having ca. 25 km in diameter. The present Rajabasa Volcano, along with cones of flank eruptions and monogenesis, has appeared in the Pre-Rajabasa Caldera depression. Those volcanic activities are considered as the second construction period. During the first and the second construction periods, basaltic to andesitic lava flows, pyroclastic breccias, and tuffs were erupted. The Rajabasa eruption points moved in WNW - ESE direction, which were possibly controlled by a subsurface weak zone. The Pre-Rajabasa Caldera erupted voluminous Lampung Tuffs having rhyolite in composition, and they are considered as a combination of pyroclastic falls, flows, and surges, or pyroclastic density currents.
Examining the Effects of Economic Policy Uncertainties on the Stock Market Index: Analysis by Nonlinear ARDL Method for G7 Countries

Published: April 2024

Uncertainties are important factors that influence the decisions made by societies. Economic uncertainties closely affect society’s consumption and investment behaviour. Rising stock markets increase investors’ confidence, resulting in more purchases and higher stock prices and, in this context, an increase in consumer spending. When stock prices decrease, company investments are also negatively affected as consumer spending declines. Thus, increases and decreases in stock prices affect the general economy as they affect business confidence and consumers. The study analyses the effect of uncertainty in economic policies on stock markets, leading to a decrease in investor confidence in the economy. Such effects in G7 countries were examined using the nonlinear autoregressive distributed lag (ARDL) model for the period 1998:M05–2020:M09. This method was able to capture symmetries and asymmetries in the relationship between economic policy uncertainties and the stock markets. The results showed that heightened uncertainty in economic policy in Japan has a significantly negative effect on the stock market index, but in Germany and Italy, it has a significantly positive effect. Rising interest rates have negatively affected the stock market index in the United States, Canada, Japan, Italy, and the United Kingdom. The increase in the industrial production index is positively related to the stock market index in the United States, Canada, Japan, Italy, and France. Additionally, uncertainties in economic policy have asymmetric impacts on the stock market index in the United States, Canada, Japan and Italy, and symmetrical impacts in Germany, France and the United Kingdom.

In the pre-sanction period, foreign economic relations in Russia were growing in importance. While the country’s gross domestic product increased by 1.75 times in 2013 compared to 2000, imports increased by 5.7 times in comparable prices during this period. Despite actual and potential effects of comparative advantages, the growing dependence on foreign markets also had negative consequences. The study assesses the demand for imported goods, considering the existing interindustry relations in the Russian economy. The paper describes the first stage of comparison of direct and total costs for the Russian economy and presents mathematical tools used to calculate indicators of its import dependence. In the future, we are planning to extend this approach to examine the spatial economy of two macrozones, namely, the European and Asian parts of Russia. Statistics show that the direct import intensity of the Russian economy is approximately 6 %, which is less than the global average. The vertical specialisation index of about 11 % indicates a relatively low dependence of the export of domestic goods on imports. In 2014–2020, total import costs reduced the most in the pulp and paper industry (-5 %) and vehicle manufacturing industry (-3 %) mainly due to a decline in their import intensity. In general, the impact of forced import substitution turned out to be negative for most regions after 2013. The proposed methods can be used to forecast the trade balance and consequences of implementing various import substitution policies. Since that intermediate consumption flows are included in indirect and total costs, it is advisable to develop a methodology accounting for investment goods.

Thirteen parameters with multiple levels are considered LAYERHEIGHT, WALLTHICKNESS, TOPBOT-TOMTHICKNESS, TOPBOTTOMLINEDIRECTION1, TOPBOTTOMLINEDIRECTION2, INFILLDENSITY, INFILLLINEDI- RECTION1, INFILLLINEDIRECTION2, PRINTSPEED, EXTRUSIONTEMP,  BEDTEMP, WORKSPACETEMP and POSITION.

Results: Type IV tensile specimens are fabricated and tested with a universal testing machine. Maximum stress is measured, evaluated and analyzed in three different building positions. Machine learning algorithm with Orange Data mining software are used to study underlying relations between factors and response. Experimental results indicate that INFILLDENSITY, TOPBOTTOMTHICKNESS and INFILLLINEDIRECTION1 has a strong positive correlation with mechanic properties for ABS and PLA. Meanwhile, TOPBOT-TOMLINEDIRECTION1, WORKSPACETEMPERATURE and PRINTSPEED has a negative correlation with tensile strength. Position 1 and 3 with line depositions parallel to Y axis produce the higher tensile strength response.

Conclusions: Findings imply that machine algorithms can be used to study multiple parameters at a time.

OBJECTIVE: This study investigates the therapeutic efficacy of sericin in rats with knee osteoarthritis (KOA) induced with monosodium iodoacetate (MIA), focusing on evaluating its effectiveness through the TGF-β/Smad pathway.
MATERIALS AND METHODS: The KOA model was established by injecting MIA into the knee joint and the rats were randomly divided into three groups:group 1 (control), group 2 (KOA control), and group 3 (KOA+sericin). Sericin was administered intratendinously to rats on days 1,7,14, and 21 (50 µL,0.8 g/kg/mL). After 21 days, the rats were sacrificed, and serum samples were analyzed using the ELISA method to measure TGF-β1, Smad2, and CTGF levels. Additionally, knee joint samples underwent histopathological evaluations with hematoxylin-eosin staining and immunohistochemical assessment using TGF-β1 and Smad2/3 antibodies.
RESULTS: Serum TGF-β1 and CTGF levels were significantly increased in group 2 vs. group 1 (P

Despite the burgeoning Latinx student population in the United States, a conspicuous gap exists in the academic literature, particularly within the National Collegiate Athletic Association (NCAA) context. Consequently, the central objective of this study was to redress this void by analyzing the racial experiences encountered by NCAA Division I Latinx student-athletes enrolled in Predominantly White Institutions (PWIs). To fulfill this objective, the researchers applied a qualitative phenomenological approach, seeking an in-depth comprehension of the significance of diversity practices within the distinct educational milieus inhabited by the study’s participants. Employing Latin Critical Race Theory (LatCrit) as the theoretical framework, the authors gathered data through six semi-structured interviews and supplemented this information with pertinent diversity and inclusion-related information derived from each participating university and the respective athletic programs. The study’s findings underscored the persistent issue of racial discrimination confronted by NCAA Division I Latinx student-athletes within the university setting. Remarkably, despite the extensive diversity, equity, and inclusion (DEI) trainings and councils within these institutions, Latinx student-athletes continued to grapple with racial disparities. Indeed, recurring themes from the data highlighted their significant reliance on familial support and campus resources as strategies for navigating and mitigating these challenges. In light of a substantial body of scholarly work that recognizes the critical importance of DEI in sport, this study serves as a poignant reminder of the pressing need for further academic and practical endeavors aimed at effectively addressing racial disparities.

The article discusses the application of the system dynamics methodology for simulation of controlled traffic flows. In the classical formulation, system dynamics models represent a system of finite-difference equations, which is an approximation of the Cauchy problem by the Euler method. The implementation of finite-difference equations in system dynamics by J. Forrester is carried out by the DYNAMO specialized graphical tools. It is proposed that the Cauchy problem be implemented using structural diagrams in which a one-to-one correspondence of specific structural links to system dynamics paradigms is established. As a result of the research, it was shown that an aperiodic link with a typical nonlinear “saturation” function identifies with a sufficient accuracy the basic paradigms of system dynamics, such as rates, levels and delays. It is shown that the resulting system of ordinary differential equations, when imposing control conditions, has discontinuities of the first kind in derivatives and requires integration methods with a variable step and variable order for effective solution. The proposed approach to modeling traffic flows, in contrast to the classical one, allows the use of modern modeling tools with a graphical language of structural diagrams and a library of methods for numerical analysis of complex dynamic processes. The implementation of a specific test scenario for modeling traffic flows was carried out in the SimInTech software package. The efficiency metrics of integration methods are obtained. A comparative analysis of the effectiveness of integration methods in solving this problem was carried out. It is shown that the most effective in solving problems of the considered class are the explicit adaptive integration methods ARK21, AM61 with a variable step from the SimInTech library, which are much more effective than the explicit Euler method in classical system dynamics.
Фактуальная онтология Квентина Мейясу?
Authors: Devaykin Igor'
Published: April 2024

Квентин Мейясу известен как один из самых ярых борцов с корреляционизмом в современной философии. Однако в отличие от негативной части его программы (направленной на критику корреляционизма), позитивная часть почти никогда не обсуждается философским сообществом. Не существует текста, в котором бы Мейясу системно изложил свой проект, предлагаемый им взамен корреляционизму. Мы реконструируем этот раздел философии Мейясу и покажем, удастся ли мыслителю решить задачи, которые он ставит в рамках своего проекта. Под корреляционизмом Мейясу понимает совокупность посткантовских концепций в философии, которые отрицают возможность познания независимой от мышления реальности и предлагают сосредоточить исследование на связи (корреляции) между мышлением и реальностью как таковой. Стоит согласиться с Мейясу — с данным способом философствования следует бороться, поскольку он недостаточно рефлексивен в отношении собственных предпосылок, а также неправомерно сужает поле философской работы. По Мейясу, корреляционизм преодолевается указанием на фактуальность, понятую как абсолютное отсутствие достаточного основания у чего бы то ни было, включая корреляционизм. Фактуальность как абсолютная безосновность представляет собой независимую от субъекта реальность, а также выводит философию за пределы корреляционизма. Учение, которое занимается исследованием свойств фактуальности, Мейясу называет фактуальной онтологией. Философ обосновывает фактуальную онтологию посредством, во-первых, возвышения ее над всеми дискурсами, во-вторых, очерчивания поля ее деятельности. В результате критического анализа проекта Мейясу, мы приходим к выводу о несостоятельности фактуальной онтологии, поскольку она усиливает корреляционизм, а не преодолевает его. Тем не менее, по нашему мнению, философии стоит переключить внимание на повседневное давление реальности как таковой на чувственность субъекта, поскольку это способствует снижению роли корреляцонизма.
О преподавании логики
Authors: Krouglov Alexei
Published: April 2024

Начальный этап университетского преподавания логики в Российской Империи, отличавшийся пропедевтическим характером логики, зависимостью от хорошего учебника и тесной содержательной и дидактической связью с метафизикой, а также развитие в университетском курсе гимназического преподавания логики, в котором важная роль отводилась проблемам практической логики, сравнивается по данным параметрам с современным состоянием университетского преподавания логики в Российской Федерации. Показано, что при традиционном начальном месте логики в процессе университетского обучения она во многом потеряла свое былое пропедевтическое содержание, а в силу отсутствия преподавания логики в школах не может начинать с более высокого уровня, предполагающего наличие первоначального знакомства с предметом. Былая практическая логика почти полностью пропала из университетских курсов по логике, а на выполнение ее былых функций претендуют новые, альтернативные ей академические дисциплины. Несмотря на разнообразие новых пособий и руководств по логике, так и не появилось такого учебника, который убедительно бы показывал и обосновывал значимость логики в изменившихся условиях. Отказ от решения возникших проблем приведет к дальнейшей элиминации и редукции логических курсов не только на нефилософских, но и на философских факультетах.

Логика как формальная философия и искусство концептуального дизайна
Authors: Dragalina-Chernaya Elena
Published: April 2024

В статье демонстрируется актуальность трактовки логики как формальной философии и искусства концептуального дизайна для университетского образования. Плюрализм современной логики привел к утрате ею функций нейтрального арбитра и индоктринирующего наставника, но, вместе с тем, выявил уникальность ее роли в концептуальной инженерии. Искусство концептуального дизайна, то есть разработки концептуальных паттернов для формальной экспликации философских понятий и техник, а также постановки новых философских проблем, является главной целью логики как формальной философии. Ни логика, ни металогика, нагруженные собственными эпистемическими обязательствами и онтологическими допущениями, не могут быть объективными судьями для логических чужаков, которые не подчиняются их предписаниям. Однако техники концептуального дизайна, разрабатываемые неклассическими логиками, служат не только эффективным средством философской экспликации, но и тренингом ключевой эпистемической добродетели — научной объективности, требующей логической дисциплины как ответственного и рефлексивного исполнения принимаемых в любом научном исследовании эпистемических обязательств. Методическим ключом к академическому курсу логики как формальной философии является корреляция процедур концептуального дизайна в логике и философии. В статье приводятся примеры такой корреляции, а также обращается внимание на артефакты формальной инженерии в философии, которые могут служить эвристиками для разработки новых инструментов формальной экспликации философских интуиций.
Можно ли утверждать наличие корреляции между политикой и логикой?
Authors: Bazhanov Valentin
Published: April 2024

В статье предпринимается попытка на историческом материале показать возможность корреляции состояния логико-математического знания и доминирующих в обществе политических установок. Утверждается, что такого рода зависимость особенно очевидна в случае исторического развития России и СССР. В статье обосновывается, что, начиная с античности, когда зачатки демократических традиций обсуждения важных вопросов жизни полисов, в период условно называемый Новым временем, когда в математике конкурировали синтетическая и аналитическая программы, первую половину ХХ столетия и до современности, что политические доктрины оказывали и оказывают более или менее выраженное влияние на состояние логико-математического знания и логическое образование. В то же время, внимание со стороны административных структур к логико-математическому знанию и особенно логическому образованию способно несколько снижать уровень идеологического воздействия на социум, повышая градус разлитой в нем рациональности. Высказывается гипотеза о наличии некоторого рода корреляции между отношением государства к логико-математическим дисциплинам и статусу логического образования в отечественной истории и возможности трансформации его доминирующих политических установок. Эта корреляция выражается в том, что расширение ареала логического образования является своего рода индикатором возможности транзита российского общества в направлении реформ, ослабляющих в нем функционал принципов консерватизма. Предлагается объяснение оснований этой зависимости с помощью новейших данных из области нейронауки, которые свидетельствуют о том, что аналитическое мышление, которое формируется в процессе логического образования, снижает градус «верований», играющих важную роль в любой идеологической доктрине и позволяет более объективно оценивать валидность заключений, которые производят политические акторы.
