Authors: Barua Prabal , Islam Md Mazharul , Mitra Anisa
Published: November 2022

The present study assessed the socio-economic circumstances of the fishermen of Kaptai lake, situated beside the Rangamati Sadar in the Rangamati district. The present study found that 4 categories of cast fishermen are engaged in fishing or fisheries-related activities. Moderate literacy rates were found among the tribal fishermen as only 15% of people were entirely illiterate, and 6% were above higher secondary education. The tribal fishermen in the surveyed area were mainly poor; their annual income ranged closely between Tk. 24000 and Tk 38400. Around 49% of houses were made of bamboo fences, whereas 27% were found to be made of mud, and only 6% of brick was built. 51.5% of the fishers' families had no adequate sanitation system, whereas earthen and sanitation latrines were found at 40% and 8%, respectively. About 45.5% of the tribal fishermen had little access to pure drinking water. The tribal fishing community suffers from various problems such as extortion, lack of fishing gear, inadequate credit facilities, ineffective marketing system, etc. Finally, it may be concluded that the socio-economic condition of the tribal fishermen is not indifferent to other traditional fishermen of Bangladesh.

Published: November 2022

Sedentary lifestyle combined with aging is associated with the genesis and development of cardiovascular diseases, Evidence for prescribing exercise in metabolic disorders in young and middle age individuals is overwhelming, but little is known regarding the effect of multicomponent exercise programs on the elderlies' metabolic health. The aim of this study was to analyze changes in blood pressure, lipid profile and cardiorespiratory fitness in a group of sedentary older adults following a two-days weekly multicomponent training (MCT) program (60 min/session). Thirteen elderly (70.77±3.72 years; 72.38±14.39 kg; 8 female) completed 15 weeks of MCT. Tryglicerydes (TG), Total cholesterol (TC), High Density Lipoprotein Cholesterol (HDL-c), Low Density Lipoprotein Cholesterol (LDL-c), blood pressure, and cardiorespiratory fitness were evaluated before and after training. Pre-post results showed significant improvements in cardiorespiratory fitness and blood pressure (p<0.05), and a trend to significance (p=0.06) for TC. A 2-days MCT short intervention improves metabolic health in sedentary old adults, although this dose (duration and time of training) seems not enough to impact blood lipid profile in this kind of training.

Published: November 2022

Background: Tele rehabilitation can deliver rehabilitation services with the use of technology to increase patient options, deliver services more efficiently and overcome geographical barriers to healthcare access. Despite its popularity, there is conflicting evidence for its effectiveness. Therefore, the aim of this systematic review was to update the current evidence base on the effectiveness of tele rehabilitation for stroke. Objective: We aimed to provide an updated systematic review on the efficacy of tele-rehabilitation interventions for stroke survivors. Method: PubMed, Google scholar, Physiotherapy Evidence Database (PEDro), Cochrane Library were searched, and the studies which were RCT, had tele-rehabilitation interventions, Published in English language, had moderate to high methodological quality (PEDro scoring 5 or more than 5). Results: Out of 218 studies, 04 randomised controlled trials met the eligibility criteria and quality assessment and were selected for the present systematic review. A diverse range of interventions were delivered through a variety of tele rehabilitation systems. Summarized findings from the heterogeneous evidence base indicate that tele rehabilitation may have a positive impact on a range of primary and secondary outcomes. Conclusion: Tele rehabilitation, as an alternate form of rehabilitation for people with stroke, shows potential. This updated systematic review provides evidence to suggest that tele-rehabilitation interventions have either better or equal salutary effects. However, due to methodological and practical concerns, an unequivocal recommendation cannot be made. Findings from this review may inform future policies and practices regarding the use of tele rehabilitation for stroke patients.
Study of the Neon Dielectric Barrier Discharge on a Capacitively Coupled Radio Frequency at a Low Pressure with Metastable Atom Density: Effect of the Pressure
Authors: Bouchikhi A.
Published: November 2022

We study the neon dielectric barrier discharge with metastable atom density on a capacitively coupled radio frequency at a pressure of about 4–12 Torr. The transport parameters of neon are dependent on the electron energy, and their range is about 0.04–50 eV. A one-dimensional fluid model and the drift-diffusion theory are used to describe the neon dielectric barrier discharge. The effect of the gas pressure on the properties of neon dielectric barrier discharge is presented for the cycle-averaged regime. It is shown that the particle densities, electric potential, and metastable atom density increase with the pressure. In addition, the surface charge concentration and the gap voltage increase as well.

The Development and Validation of Jihad Academic Scale (JAS)
Authors: Nugraha M. Fadli
Published: November 2022

The purpose of this study was to construct and validate the jihad academic scale. Because jihad is broadly divided into major (non-physical) and minor (physical) jihad, this research focuses on the construction of the major (non-physical) jihad, which is carried out in the academic or how they strive to study in their education. The study consisted of a pilot study (n=61), a first study (n=183), and a second study (n=183), using a convenience sampling technique. A quantitative method with exploratory factor analysis (EFA) design followed by confirmatory factor analysis (CFA). Validity uses to construct convergent and discriminant validity—analysis using the JASP program. The results of the EFA study formed three dimensions. The CFA results stated that the proposed model was fit based on the CFI=0.94 (> 0.90) SRMR=0.05 (< 0.08) GFI=0.91 (> 0.90). But still not fit in accordance with p-value 2=0.01 (> 0.05) and RMSEA=0.06 (< 0.05). Then it has been reliably seen from α = 0.88 (> 0.70). Then the convergent validity is seen from the academic resilience scale with the correlation value of Pearson's (r = 0.41) and Spearman's (rho = 0.35) with each masing p-value < .001. Then, for discriminant validity, it can be seen from the school burnout inventory scale with the correlation value of Pearsons (r = - .11) with p-value=.012  and spearman's (rho = - .21) with p-value= .00438. The normality assumption of Shapiro-Wilk (W= 0.87) with p-value < .001. Overall, this scale can be used in a university environment and can then be developed at other levels of education with a larger number of samples to confirm each factor.

Authors: Layyinah Naiva Urfi , Kumalasari Asteria Devy
Published: November 2022

Positivity, the tendency to view self, life, and the future positively, and to believe in others, was found to contribute toward an individual’s functioning based on previous studies. A positivity scale in the Indonesian version is needed to understand better Indonesian people’s functioning and improve their well-being. However, the positivity scale was not yet available for Indonesians. This study aimed to adapt the 8-item Positivity Scale into Positivity Scale Indonesian Version (PSIV) and find evidence of its psychometric properties. Data from 218 Indonesians aged 18 years or older were collected using an 8-item PSIV rated on a 5-point scale. The results showed good item discrimination indicated by its corrected-total item correlations (0.35–0.67) and a high internal consistency (α=0.826). The confirmatory factor analysis results after applying the modification model showed that the hypothesized one-factor model fit the criteria indicated by CFI=0.968, TLI=0.950, RMSEA=0.067, SRMR=0.037, and GFI=0.962. The PSIV was correlated with life satisfaction and positive and negative effects. A test-retest reliability conducted on 30 respondents showed a correlation between the first and second times of data collection. Accordingly, PSIV had adequate item discrimination, reliability, and validity. Thus, the PSIV is beneficial to assess the positivity of Indonesian people aged 18 years or older.

Published: November 2022

This study aims to investigate the psychometric characteristics of the CFIT-scale-2, including investigation of difficulty level, discrimination, distractor effectiveness, DIF (Differential item functioning), IRT (Item Response Theory) 2PL model, validity, and reliability. Respondents were 507 students with 245 (48%) females and 262 (52%) males, with ages ranged from 8-13 years (M= 10.88; SD = 1.35). The classical test theory (CTT) analysis showed that the item difficulty level on the CFIT-scale-2 had varying item difficulty levels, from easy to difficult. However, the test arrangement was not structured according to the suggested difficulty level from easy to medium to difficult. The discrimination of items was poor because 28 items were not included in the very good category (p > .40). In addition, 47 (25%) of the 184 distractors are ineffective. CFIT-scale-2 did not contain DIF (Adj.p > .05), and IRT analysis showed that the CFIT-scale-2 was not structured according to the difficulty pattern from easy, medium, and difficult. The CFIT-scale-2 based on IRT analysis contained 44 items or 96% with good discrimination. The results of a construct validity test using the CFA technique showed a good fit model (p < .001; RMSEA < .08; SRMR < .08), which was acceptable and supported the fit between the theoretical and empirical model. The reliability coefficient value of Cronbach's alpha was 0.88 (α > .70), indicating that the CFIT-scale-2 had good reliability, but the construct reliability was below an acceptable value (CR < .69). According to this study, the psychometric characteristics of the CFIT-scale-2 should be revised and reevaluated.
The Impact of Z-Score Transformation Scaling on the Validity, Reliability, and Measurement Error of Instrument SATS-36
Authors: Sumin Sumin
Published: November 2022

The Likert scale is a psychometric scale commonly used for response measurement. This measurement scale includes techniques for designing and administering surveys as well as coding and analyzing data. However, Likert scaling has various limitations that can affect the resulting data. This study aims to reprove the number of dimensions of the SATS-36 instrument, prove the validity, and estimate the reliability of the statistical attitude instrument (SATS-36) on students at religious universities in Indonesia using Z-Score Transformation Scaling. The latent constructs of cognitive competence, value, difficulty, effect, and effort were constructed using a Likert scale according to the pattern of statements on each item. This study uses confirmatory research with a quantitative approach. For students at religious universities in Indonesia, 243 respondents were selected using a stratified one-stage cluster random sampling technique. Proof of validity and estimation of reliability was done using confirmatory factor analysis. The results of this study show that the rescaling method can improve the validity of the factors but cannot increase Cronbach's coefficient of internal consistency and cannot reduce the standard error of measurement for each item. This research implies that it is not enough to rescale or transform the data to improve the validity and reliability of a measuring instrument. However, it is necessary to calibrate the statement sentence or item question so that the item measures its construct. Further research also needs to test the effectiveness of rescaling in addition to the Z-Score in improving the validity and reliability of measuring instruments.
Psychometric Properties of the Indonesian Version of Youth Quality of Life-Weight Instrument (YQOL-W)
Authors: Putri Grace Helena Firmansyah , Purba Fredrick Dermawan
Published: November 2022

Quality of life refers to a broad concept that describes life satisfaction in terms of culture, value, and life experiences which are used to explain someone’s life aspect in general or specifically in relation to a particular condition, such as being overweight or obese. Obesity causes many health problems and affects the overall quality of life. As the obesity rate continues to be a growing public health problem in Indonesian adolescents, examining the perceptions regarding their weight is fundamental for planning a proper intervention. However, there has been little reported of available weight-specific instruments that measure the QoL in Indonesia. Youth Quality of Life-Weight (YQOL-W) is a multicultural measurement of QoL-weight that was specifically recommended by previous researchers to measure the QoL of adolescents with obesity and overweight conditions. This study was conducted to evaluate the psychometric properties of the adapted YQOL-W instrument for Indonesian adolescents. Twenty-one items were administered to 880 adolescents between 11 and 18 years of age, of whom 54.55% were female and 71.14% were junior high school students. Data were collected with a convenience sampling technique. Confirmatory factor analysis showed that a three-factor model had an acceptable model fit, including a Self factor (4 items), Social factor (12 items), and Environment factor (5 items) with p < .05. The YQOL-W instrument had good internal consistency reliability with Cronbach’s alpha ranging from .87 to .95 and acceptable test-retest reliability with the intraclass correlation coefficients (ICC) all greater than .70. The one-factor and three-factor scores were negatively correlated with BMI and positively correlated with PedsQL (all at p < .01 level). In conclusion, the Indonesian version of the YQOL-W shows good reliability and validity for assessing the weight-specific QoL of adolescents in Indonesia.
Effect of eccentricity on ultimate lateral unit earth pressure of tetrapod piles in clay
Authors: Zhao Z. , Wan Y. , Dai D. , Ke L.
Published: November 2022

This study investigates the ultimate lateral unit earth pressure of rigid tetrapod foundation imposed by eccentric loads, based on a couple of two-dimensional adaptive finite-element limit analyses with lower-bound, upper-bound and 15-node mixed Gauss element formulations. A parameter study is conducted to emphatically explore the influence of eccentricity as well as to assess the role of additional parameters such as soil–pile interface strength and pile spacing on the normalised lateral earth pressure factor Np. Results from the numerical analyses reflect that the presence of loading eccentricity may lead to significant reduction in lateral soil resistance, the maximum diminution is up to 45% for the case that eccentricity equals to 0·5 times spacing. Three representative failure mechanisms are identified associated with various eccentricities. Pile spacing and interface strength additionally affect the variation of failure mechanisms with eccentricity increases. Finally, the eccentricity reduction factor, defined as the ratio of the Np considering the effect of loading eccentricity to the Np omitting this effect, is proposed, and the variation of this factor with eccentricity is presented for different values of pile spacing and soil–pile adhesion factor.

We aimed to examine the potential beneficial effects of diosmin administration on cisplatin - induced premature ovarian failure (POF) in a rat model

Material and Methods

Twenty-eight rats were divided into four groups. Group A rats (n:7) were determined as the sham group. The remaining rats received an intraperitoneal injection of 1.5 mg/kg/day cisplatin for 10 days to create a POF model. Then, they were randomly divided into 3 subgroups.

Group B was determined as POF group. Group C rats were given 100mg/kg/day diosmin for 10 days simultaneously while creating POF model. Group D rats were given 100mg/kg/day diosmin for 10 days after POF model was created. Twentieth day blood samples were taken and left ovaries were resected for examination.

Results

CIS-induced rats showed reduced levels of SOD, AMH and E2 compared to sham group rats (p0.05) between the sham group, group C and D. No significant (p>0.05) difference in FSH value was observed between group C, D and sham groups.

There was no significant (p>0.05) difference in the number of secondary and antral follicles between group C and D compared to the sham group. Primordial follicle count was significantly higher in group C than group B (p

Published: November 2022

Introduction: Carpal tunnel syndrome (CTS) is the most common entrapment mononeuropathy and can affect patients' daily living activities. In this study, it was aimed to find out whether there is a relationship between fatigue, neuropathic pain and neurophysiological features in CTS.

Material and Method: Patients with clinical features compatible with CTS were included in this retrospective study. Median nerve compound muscle action potential (CMAP) and compound nerve action potential (CNAP) of the patients were analyzed. The Turkish version of the Fatigue Severity Scale (FSS) was administered to all patients. Patients with a mean FSS score of ≥4 were considered to have fatigue. In addition, Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) was applied to some patients. If the LANSS score was 12 or higher, these patients were considered to have neuropathic pain.

Results: Thirty-two female and eight male CTS patients were included in the study. Thirty-two patients had clinically bilateral CTS and eight patients had right-sided CTS. FSS and LANSS were administered to 40 and 18 patients, respectively. There were 29 CTS patients (72.5%) with an FSS score ≥ 4. CNAP/CMAP amplitudes and sensory/motor nerve conduction velocities of patients with fatigue were lower than those without fatigue (p
Copular agreement in Hindi-Urdu
Authors: Bhatia Sakshi , Bhatt Rajesh
Published: November 2022

In this paper, we present an analysis of Copular Agreement in Hindi-Urdu. We examine assumed identity copula structures (e.g., For today, I am him.), where we show that the broad characterization of the Hindi-Urdu agreement generalization – ‘agree with the highest unmarked DP’ – is insufficient: a structurally lower unmarked nominal has a demonstrable impact on the availability of agreement with a higher unmarked nominal. This interference arises as a function of the person specifications of the various unmarked nominals in the structure. Previous approaches account for such effects either in terms of the licensing needs of the nominals involved in identity copulas (Coon et al. 2017; Keine et al. 2019), or in terms of the properties of the person agreement probe (Coon & Keine 2020). We argue that in order to account for the interference effects observed in Hindi-Urdu, a combination of both perspectives is required. Given the impact of realization on the grammaticality of identity copula sentences – verbal morphology in certain tenses and the presence/absence of copulas modulate grammaticality – a feature gluttony analysis (Coon & Keine 2020) is required. Under this approach, for certain combinations of person features, the finite agreement probe is in an agreement relationship with both the nominals in the structure. Ungrammaticality arises when there is no morphological exponent that can realize the features associated with those two agreement relationships. Further, we establish that both the DPs in identity copula structures are licensed by finite T, and thus an analysis entirely without a licensing component is untenable. We also show that the issue of licensing in copular constructions (and elsewhere) in Hindi-Urdu can be handled through the adoption of a Kalin (2018) style analysis.

In cities, trees are seen predominantly as entities that beautify streets, parks and gardens. Often they’re regarded as obstacles to urban development, where their importance to ecosystem health plays a secondary role to economic growth. How can multispecies art offer new perspectives on trees and their crucial contributions to urban life? Branching Songs is a project with old trees in the Vancouver area, including the ‘1308 Trees’, urban forest sites where trees are being cleared for the Transmountain Pipeline expansion. The intention is to bear witness to trees who are supporting the well-being of human and nonhuman life. The project combines new technologies, such as 360° photography and video, ambisonic and geophonic sound recording, biomidi data, and contact mic recording, with approaches from acoustic ecology, multispecies creativity, and performance. The Branching Songs team produced methods for working collaboratively with trees and composed a collection of soundscapes and accompanying 360° photos and videos. The soundscapes present the complex biophony and anthropophony of each site, weaving in soundings from electromagnetic fields produced by the trees and our touch interactions with the tree bodies. The touch gestures are improvisational, responding to the emergent sounds heard on site, and the specific features of the participating tree. Multiple microphones allow us to listen to varied perspectives refracted across the tree body. Our video article includes an introduction to the project, the methods we developed, two soundscape compositions and accompanying visuals with the trees in the collaboration.@font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:"Helvetica Neue";panose-1:2 0 5 3 0 0 0 2 0 4;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:-452984065 1342208475 16 0 1 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin:0in;mso-pagination:widow-orphan;font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-font-family:"Times New Roman";}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-family:"Calibri",sans-serif;mso-ascii-font-family:Calibri;mso-ascii-theme-font:minor-latin;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-hansi-font-family:Calibri;mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:minor-bidi;}div.WordSection1{page:WordSection1;}
Limits on gestural reorganization following vowel deletion: The case of Tokyo Japanese
Authors: Shaw Jason , Kawahara Shigeto
Published: November 2022

The coordination of gestures in consonant clusters differs across languages and hence must be a learned aspect of linguistic knowledge. Precisely pinning down the coordination relation used in a particular language, or for a particular consonant cluster type, has been facilitated by recent research showing that coordination relations structure kinematic variation in unique ways. We apply these methods to a hitherto under-explored topic, the coordination of consonant clusters created via vowel deletion. Our case study involves fricative-fricative and fricative-stop consonant clusters resulting from the variable deletion of devoiced vowels in Tokyo Japanese. Examination of articulatory data obtained by Electromagnetic Articulography (EMA) show that some consonant clusters, i.e., fricative-stop clusters, show gestural reorganization whereas other cluster types, i.e., fricative-fricative sequences, behave as if a vowel remains in place, despite the fact that the tongue dorsum movement for the vowel is absent from the articulatory record. We discuss several theoretical possibilities to account for the differential effects of vowel deletion on gestural re-organization in these environments.

Published: November 2022

Fish landings are routinely measured for length and weight to study fish bioecology, which provide important information about biomass, population dynamics and condition of fish. The current study describes the length-weight relationships (LWRs) and length-length relationships (LLRs) of six fish species (Cyprinus carpio, Carassius carassius, Schizothorax niger, S. curvifrons, Crossocheilus diplochilus and Pethia conchonius) based on seasonal fish sampling from the Dal Lake during September 2019 to August 2020. The estimated LWRs and LLRs were highly significant (p < 0.05) with high coefficient of determination r2 and the estimated b values ranged from 2.50 to 3.55. The estimated b values revealed negative allometric growth of fish species except P. conchonius which possesses positive allometric growth. The mean value of condition factor for C. carpio, C. carassius, S. niger, S. curvifrons, C. diplochilus and P. conchonius were 1.43±0.25, 1.55±0.24, 0.86±0.14, 0.80±0.13, 1.21±0.17 and 1.64±0.34 respectively and it varied significantly among these fish species (ANOVA: p < 0.05). The study shows LWRs, LLRs and current condition of some forage fish species viz., C. carassius, C. diplochilus and P. conchonius as well as invasive C. carpio and local Schizothorax species from the Dal Lake, all possessing economic and conservation significance.

Electrophysical properties of ceramics sintered at elevated temperatures BeO + 30 wt.% TiO2
Authors: Drokin N. A. , Kiiko V. S. , Malkin A. I. , Pavlov A. V.
Published: November 2022

The electrophysical properties of ceramics based on BeO, in which micro and nanoparticles of TiO2 were introduced, were investigated by impedance spectroscopy in the frequency range of 100 Hz ‒ 100 MHz. In order to increase the density and conductivity, sintering of the initial ceramic components was carried out at the highest possible temperatures up to 1660 °C, followed by annealing in a hydrogen atmosphere at 800 °C. At the same time, TiO2 was strongly reduced with the formation of lower titanium oxides (Ti3O5) and titanium in the metallic state. When interacting with hydrogen, TiH2 is formed. For the first time, impurity phases were found in (VeO + TiO2) ceramics, which can significantly change the properties of its volume and surface. The resulting ceramics have a high through conductivity, which increases significantly after additional thermal combustion in a hydrogen atmosphere. It is established that the activation energy of the conductivity does not depend much on the concentration of TiO2 nanoparticles and decreases significantly in the low temperature region. By the method of constructing equivalent electrical circuits, the passage of the active and reactive components of the current through the complex internal structure of ceramics is modeled. Ill. 6.

Increasing the rate of capture of pollutants by local suction due to the use of an external swirling jet. Part 1. Research methods
Authors: Zaitsev O. N. , Logachev K. I. , Gol’tsov A. B.
Published: November 2022

To capture pollutants in many buildings and structures, it is necessary to use local suction systems. One of the criteria for the effectiveness of local suction ― the rate of capture of pollutants ― it is proposed to increase due to the impact of a swirling annular jet and the occurrence of a reverse air flow. The circular suction is placed coaxially in an external cylindrical casing, in which the air flow is twisted due to the tangential supply of two supply jets into the casing. A vortex dome is formed, which helps to increase the efficiency of such a vortex suction. The change in the axial velocity of air at a distance from the vortex suction was experimentally and numerically investigated for 11 structures, in each of which 4 different ratios of intake and supply air flow rates were set. In the investigated applications of the proposed suction systems, the speed increases significantly at a certain range of distance from them. A combination of designmode parameters that contribute to the highest rate of capture by vortex suction is determined. The results obtained are useful in designing effective suction systems for capturing pollutants.
The prospect of providing metallurgy with refractories in 2022 and key factors for the near future. Part 1. Results of 2021
Authors: Aksel'rod L. M.
Published: November 2022

The directions of development of practice, organizational and technological aspects in the refractory industry in 2021, as well as the prospects for the implementation of modern approaches to improve the efficiency of the use of refractory materials in metallurgy are analyzed. The forecast of the development of trends in the industry is made under the influence of the current multifactorial situation with a decrease in the production of ordinary refractory materials, an increase in the role of refractories of the main composition of high quality, unformed refractory materials and improving the technology of using refractories in solving problems updated by customers. The main directions of development of refractory production are discussed: consolidation of business, development of research structures, relocation of production facilities to the production sites of enterprises ‒ consumers of products. It remains relevant to increase the role of refractory materials in solving problems determined by the customer's requirements: «pure steel», energy efficiency and reduction of CO2 emissions, unit costs and increasing the durability of the lining of metallurgical units.

Gibbs paradox as a derivative of composition entropy
Authors: Barsky E.
Published: November 2022

In science, sometimes so-called «problem problems» arise, over the solution of them struggle for a long time several generations of scientists. Possessing deep knowledge and developed intuition, they sometimes predict the result of a problem, but cannot find a solution to it. Among such problems of science, one can certainly include the problem that entered physics under the name «Gibbs paradox». Gibbs predicted all the properties of the entropy of a mixture. He showed that when two different gases are mixed, the entropy of the mixture exceeds the sum of the initial entropies of the components by an amount that called the jump of entropy. What is the physical nature of this jump, he could not explain. The fact is that this jump of entropy behaves in a rather strange way. Its magnitude does not depend on the nature of gases, for a mixture of them of any arbitrary chemical composition, it has the same value. For more than a century there has been a paradox Gibbs associated with the fundamental parameter of physical systems ― entropy, and so far no one has been able to clarify this paradox or at least find out due to what reasons it is formed.

The possibility of laser cutting of plasma-sprayed refractory products made of aluminum oxide was investigated. The industrial laser complex KS-5VDM1-3 Navigator (VNITEP, Russia), equipped with an LS-3 ytterbium fiber laser with a power of 3 kW, was used to work out the cutting conditions. It was found that immediately after the completion of the plasma spraying process, the phase composition of the article material is a set of various modifications of aluminum oxide. Subsequent heating of these items leads to a series of polymorphic transformations accompanied by changes in the volume and density of the item material. The process ends when all polymorphic modifications of aluminum oxide pass into the only stable phase α-Al2O3 (corundum). It was shown that laser cutting of plasmasprayed aluminum oxide products is possible only when the process of transition of all its phase modifications to corundum is completely completed. Otherwise, a sharp change in the volume of the product material, caused by polymorphic transformations occurring under conditions of a high temperature gradient that occurs during laser cutting, leads to the destruction of the product. Plasmasprayed product, the material of which is entirely α-modification of aluminum oxide (corundum), is not afraid of high temperature gradients and is easily laser cut without destruction. Cutting data can vary widely. The cutting technology of plasma-sprayed refractory products made of aluminum oxide has been mastered at the Scientific and Educational Center for the Implementation of Laser Technologies at the Vladimir State University.

Published: November 2022

This research studied the process of irregular urban occupations that occurred along the Cuiabá River Permanent Preservation Areas (PPAs), as a key to understand its importance for urban sustainability. Its objective was to study the dynamics and socio-environmental impacts resulting from irregular occupations along the banks of the river that cuts through the two largest cities in the Metropolitan Region of the Cuiabá River Valley - RMVRC/MT, the state capital Cuiabá, and Várzea Grande. Considering that this river is responsible for the water supply of both cities, and a Pantanal Mato-Grossense affluent, which have a fundamental relevance for the local and regional ecosystem, it became important to identify the contradictory relationships between socio-environmental issues and the application and surveillance of urban legislation, by mapping the APPs, in order to verify the degradation of the Cuiabá River. The methodology was based on bibliographic, documental and empirical research. The results showed the importance of its continuity in new research, and may also subsidize decision-making processes, formulation of urban and environmental legislation, public policies aimed at socio-environmental protection of vulnerable areas, relevant to improving the quality of life and the environment.

Published: November 2022

Kadının toplumsal, tarihsel ve sosyolojik alanlardaki yerinin pek çok farklı disipline konu olduğu görülmektedir. Özellikle sosyoloji alanında kadın ile ilgili yapılan çalışmalar kadının gerek özel gerek toplumsal alanlardaki durumunu aydınlatmaktadır. Sosyolojinin bir alt dalı olarak görülen beden sosyolojisi hem Türkiye sınırları içerisinde hem de dışında kalan coğrafyalarda, özellikle Batı’da çeşitli araştırmalara konu olmaktadır. Yaklaşık olarak yirminci yüzyılın sonlarından itibaren sistemli bir şekilde araştırmaya başlanan beden sosyolojisi bedenin tarihsel ve sosyal süreçler içerisinde oluşumunu incelemekte ve spor, tıp, edebiyat ve benzeri gibi farklı alanlarda da kullanılmaktadır. Edebiyat eserlerinde kurgulanan dünyaların ve karakterlerin analizlerine ilişkin sıklıkla başvurulan sosyolojik eleştiri kuramının altında değerlendirilecek olan beden sosyolojisi bu çalışmanın yöntemini oluşturmaktadır. Araştırmaya milattan önce beşinci yüzyılda kaleme alınan Aristofanes’in Lisistrata adlı tiyatro eseri ile bu eserden hareketle uyarlanan ve Kartal Tibet’in yönetmenliğini yaptığı 1983 yılında çekilen Şalvar Davası adlı sinema filmi konu olmaktadır. Eserlerde kurgulanan kadın karakterlerin içinde bulundukları durumların ve motivasyonlarının incelenmesi hedeflenmektedir. Her iki eserde yer alan kadın karakterlerin politik ve kamusal alana dâhil olmak adına bedenleri üzerinden yürüttükleri mücadele incelenecektir. İki farklı sanat alanı arasındaki benzerlikleri karşılaştırmalı bir çalışma yürüterek saptamaya çalışmak ve eserlerde yer alan kadın karakterlerin yürüttükleri mücadelenin sonunda sınırlarını zorladıkları ataerkil kültürü nasıl pekiştirdiklerini yansıtabilmek bu çalışmanın amacını oluşturmaktadır.
“STATUS SOCIETY”: SOCIOLOGICAL THINKING OF GÖBEKLI TEPE AND KARAHAN TEPE IN THE CONTEXT OF SOCIAL STRATIFICATION
Authors: AYAZ Orhan , ÇELİK Bahattin , ÇAKMAK Fatma
Published: November 2022

Göbekli Tepe and the Neolithic sites around Urfa, which were identified by surveys, provide rich data for the transition of human beings from hunter-gatherer groups to settled and semi-settled agricultural societies. It is possible to trace most of the institutional foundations of today's societies to this transition period. Social theory, which was heavily influenced by the "Neolithic revolution" paradigm, ignored this transitional period. Sociological thought categorizes societies as hunter-gatherer and agricultural societies starting from the back and moves from the axiom that hunter-gatherer societies are egalitarian and agricultural societies are hierarchical. On the other hand, archaeological studies, while addressing the hierarchical "nature" of Neolithic societies, do not sufficiently benefit from the relatively rich theoretical background of sociology. As a result, it becomes important that the two disciplines work in cooperation. This study will emphasize that egalitarian hunter-gatherer groups lived in a relatively long transition period before class-based stratification originating from the economy, and that they went through a hierarchical social order based on social prestige rather than economic inequality during this transition period. For this, Weber's concept of status, which emphasizes different inequalities, rather than Marx's conceptualization of class division based on the ownership of the means of production, will be taken into consideration. Göbekli Tepe society was a classless society, but a hierarchical society based on status. It is possible to define societies that share Göbekli Tepe culture as "status society" in which individuals and groups have prestigious status on an ideological basis. In this scenario, some people had a more prestigious position than others because they monopolized the mythological narrative that made the world meaningful, causing social differentiation. Unlike the main claim of social conflict analysis, the article will argue that the symbolic world, which expresses the social hierarchy in Göbekli Tepe culture, has important functions that enable the Neolithic lifestyle, besides providing a meaningful explanation of the social world rather than causing an exploitation mechanism against a part of the Neolithic society.
RISE OF GÖBEKLI TEPE CULTURE: “HUNTING GROUND ECONOMY” AND THE ROLE OF SPECULATIVE “KNOWLEDGE”
Authors: ÇELİK Bahattin , AYAZ Orhan
Published: November 2022

At the beginning of the Early Holocene Period, the hunter-gatherer groups in the Upper Mesopotamia region left behind complex structures, monumental stone pillars, and various sculptures and Neolithic cultural zone that stand out with rich symbolism accompanying thereto in unprecedented permanent settlements. Excavations were initiated at new Neolithic hills within the scope of the “Taş Tepeler” project in Göbekli Tepe cultural zone, rather known for Göbekli Tepe Neolithic Period site. By whom, how and why this early Neolithic civilization that reverses some basic assumptions on the history of the mankind remains the most important area under discussion. The excavations currently in progress, and the surveys carried out, at the Neolithic sites in this culture region provide comprehensive data on the social and economic foundations that allowed rise of this civilization. In particular, the prevalent and enormous hunting grounds/entrapment areas discovered in this region stand out as the most important economic grounds that allowed this civilization to rise. Moreover, the finds referring to the material exchange and craftsman network conducted in a wide area appears as another socio-economic factor. Despite recognizing the socio-economic foundations, this study shall place the speculative "knowledge" highlighting the psycho-cultural aspect of the people of that era as the main triggering driver regarding rise of this civilization. In conclusion, this study shall endeavour to deduct reasonable interpretation on how Göbekli Tepe culture started to rise on the basis of the sociological perspective that considers knowledge at an autonomous place against other socio-economic conditions.
VUSÛLÎ DÎVÂNI’NDA TAKILAR

Published: November 2022

Divan şiirinde takılar güzelliği tamamlayan unsurlardır. Klasik Türk şiirinde şairlerin tamamı sevgilinin güzelliğini tasvir ederken takılardan yararlanırlar. Tasvir edilen sevgili daha çok üzerinde bulunan takılarla beraber şiirlere konu olmuştur. Şiirler yazıldığı dönemin sosyal ve kültürel yapısı hakkında bilgi sahibi olmamızı sağlıyor. Bu çalışmada 16. yüzyıl şairi olan, Vusûlî Divanı’nda geçen takılarla ilgili unsurlar ve bu unsurların beyitlerde nasıl kullanıldıkları, hangi sözcüklerle birlikte kullanıldığında bu unsurlara çağrışımlarda bulunduğu üzerinde durulmuştur. Klasik Türk şiirinde sevgilinin güzelliğine güzellik katan unsurların olmaması düşünülemez. Vusûlî Divanı taranıp takılarla ilgili kaç tane unsurun olduğu ve bu unsurların hangileri olduğu üzerinde durulmuştur. Çalışmada unsurlar sıralanmıştır. Baş takıları (mengûş, tâc), boyun takıları (tavk, silk-i cevâhir), bel takıları (kemer), el takıları (hâtem) olarak incelenmiştir. Klasik Türk şiirinde sevgiliyi en güzel ve en mükemmel şekilde tasvir etmek amaçlanmıştır. Bundan dolayı konu aldığımız beyitlerde sevgili betimlenirken hem dönemi hem de o dönemde takılan takılar göz önünde bulundurulmuştur. Sevgili bazen ay olur geceyi süsler bazen de güneş olur günü aydınlatır. Sevgilinin bu güzel hali takılarla birleşince eşsiz bir manzara ortaya çıkmaktadır. Bunlar karşısında değişmeyen tek şey sevgilinin acımasız ve âşığına eziyet çektirmesidir. Tabii ki bu durum âşığın onu sürekli düşünüp aşkının artmasına engel değildir. Vusûlî dönemindeki takıları en ince ayrıntısına kadar işlemiştir.
