The effect of osteoarthritis exercise on pain and joint range of motion in osteoarthritis patients

Aims. Osteoarthritis is a degenerative and progressive disease characterized by abrasion of joint cartilage and irregular formation of new bone on the surface of the joints. Pain becomes the main symptom followed by a decrease in joint range of motion, causing disability and interfering with daily activities. The purpose of this study was to determine the effect of osteoarthritis exercise on pain and joint range of motion in osteoarthritis patients. Methods. The research design used a quasy experiment with a non-equivalent control group design approach. The sample used was 70 respondents for each intervention group and control group. Intervention in the form of physical exercise osteoarthritis exercise guided by an instructor and using audio-visual media. Exercise is carried out 3 times a week for 2 weeks. For stretching and flexibility exercises using yoga mats and bath towels and for strength building exercises using chairs. The pain scale was measured with a numeric rating scale (NRS) instrument and measurement of joint range of motion using a goniometer. Data analysis used numerical comparative analytic paired-sample t test and independent t test. Findings. The results showed that the results of the paired t test (p) <0.05. thus indicating that there is an effect of providing osteoarthritis gymnastics training intervention on reducing the pain scale. The results of the paired t test (p) <0.05. thus indicating that there is an effect of providing osteoarthritis exercise training interventions on the scale of joint range of motion. The results of the independent t test (p) <0.05, meaning that there is a difference in the osteoarthritis pain scale before and after the intervention, while the test for differences in joint range of motion scale shows a non-significant value of p> 0.05. Conclusion. The conclusion of the study was that there was an effect of osteoarthritis gymnastics training in reducing the osteoarthritis pain scale and joint range of motion scale. Then there is no difference between the control group and the intervention group who get gymnastic exercises and do not get osteoarthritis gymnastic exercises.

Psychological wellbeing in Chinese university students: insights into the influences of academic self-concept, teacher support, and student engagement

Objective This study investigates the complex interplay between academic self-concept, teacher support, student engagement, and psychological wellbeing among Chinese university students. We aimed to elucidate the mediating role of student engagement in these relationships. Methods A sample of 597 Chinese undergraduate students from diverse universities participated in the study. We employed structured questionnaires to assess academic self-concept, teacher support, student engagement, and psychological wellbeing. Confirmatory factor analyses and structural equation modeling were used to test our hypothesized model. Results Structural equation modeling indicated that the partial mediation model, which considered both direct and indirect effects, outperformed full mediation and direct effect models. Student engagement significantly mediated the relationships between academic self-concept, teacher support, and psychological wellbeing. Importantly, teacher support demonstrated a direct impact on psychological wellbeing, even when accounting for the mediating role of student engagement. Conclusion This study underscores the pivotal role of student engagement as a mediator in the relationship between academic self-concept, teacher support, and psychological wellbeing among Chinese university students. While student engagement plays a substantial mediating role, our findings also recognize the persistent direct influence of teacher support on psychological wellbeing. These insights have implications for educators and policymakers aiming to enhance the wellbeing of university students by fostering positive academic self-concept and teacher support while recognizing the importance of student engagement.
Relations of Alpine Plant Communities across Environmental Gradients: Multilevel versus Multiscale Analyses

Alpine plant communities vary, and their environmental covariates could influence their response to climate change. A single multilevel model of how alpine plant community composition is determined by hierarchical relations is compared to a separate examination of those relations at different scales. Nonmetric multidimensional scaling of species cover for plots in four regions across the Rocky Mountains created dependent variables. Climate variables are derived for the four regions from interpolated data. Plot environmental variables are measured directly and the presence of thirty-seven site characteristics is recorded and used to create additional independent variables. Multilevel and best subsets regressions are used to determine the strength of the hypothesized relations. The ordinations indicate structure in the assembly of plant communities. The multilevel analyses, although revealing significant relations, provide little explanation; of the site variables, those related to site microclimate are most important. In multiscale analyses (whole and separate regions), different variables are better explanations within the different regions. This result indicates weak environmental niche control of community composition. The weak relations of the structure in the patterns of species association to the environment indicates that either alpine vegetation represents a case of the neutral theory of biogeography being a valid explanation or that it represents disequilibrium conditions. The implications of neutral theory and disequilibrium explanations are similar: Response to climate change will be difficult to quantify above equilibrium background turnover.
Changes Of Productive Returns Against Ownership Structure

Ownership structure has been a prime variable in corporate governance literature. The structure of the ownership of corporate governance, influence the value of the firm. As proposed by agency theory, different ownership structure leads to varied level of managers’ motivation and engagement, which in turn leads to value creation. Using panel data for period 2011-2022 for a sample of listed firms in India, the study attempts to see a how the varied ownership structure influences the productivity of a firm - measured in terms of accounting performance measures while taking firm size, firm age, and leverage as control variable. Being multidimensional variable, the ownership is being analysed along the dimensions such as shareholders’ concentration, identity among others for its effects on the performance.
Enhancing organizational behaviour through corporate governance: The crucial role of organizational culture and sustainability

Corporate sustainability (CS) has become the world’s most persistent matter, which enormously enhances the success of organizations. The purpose of the study is to explore the factors that affect CS in small and medium-sized enterprises (SMEs) in Saudi Arabia. The study develops a model based on vigorous literature and proposes a few hypotheses based on the studies of Moslehpour et al. (2022) and Wijethilake et al. (2023). The study employed a survey strategy and found the results on 336 valid samples. The researchers applied a path analysis using SmartPLS 4 to predict the effects. The results of the study demonstrate a positive significant impact of organizational culture (OC), business infrastructure (BI) and corporate governance (CG) on CS. On the other hand, corporate alignment (CA) is a negative significant predictor of CS. Besides, CG mediates the relationship between OC, BI and CS but does not mediate the connection between CA and CS. The SMEs’ top management may enhance performance by considering OC, BI, CA and CG constructs. Finally, the findings support to literature to overcome gaps in the direct and indirect role of CG integrated with OC, BI and CA towards CS.
Nonbreeder birds at colonies display qualitatively similar seasonal mass change patterns as breeders

Abstract The difficulty in studying nonbreeding birds means that little is known about them or their resource requirements, despite forming a large and significant component of a population. One way to assess food requirements is to examine changes in body mass, because it indicates the amount of food acquired. In terms of body mass changes, our expectation is that nonbreeders will either (a) be in poorer condition than the breeders which potentially explains why they do not breed or (b) remain at a stable higher mass as they are unconstrained by the physiological costs associated with rearing chicks. Here, we interrogate body mass datasets of breeding and nonbreeding birds of two penguin species to assess these predictions and determine whether differences in mass exist between these two groups throughout the breeding season. The first dataset is from a wild Adélie penguin population, where bird mass was recorded automatically and breeding status determined from a resighting program. A second population of captive gentoo penguins were weighed regularly each breeding season. We demonstrate that although there were times in each year when breeders were heavier than their nonbreeding counterparts for both populations, the mass changes showed qualitatively similar patterns throughout the breeding season irrespective of breeding status. Heavier breeders at times during the breeding season are not unexpected but the overall similar pattern of mass change irrespective of breeding status is in contrast to expectations. It appears that breeding status per se and the constraints that breeding places on birds are not the only driver of changes in mass throughout the breeding season and, although not explicitly studied here, the role of hormones in driving changes in appetite could be key to explain these results. These results present a significant step toward understanding food requirements of nonbreeders in avian populations.
Numerical Simulation for Natural State of Two-Phase Liquid Dominated Geothermal Reservoir with Steam Cap Underlying Brine Reservoir

Hydrothermal reservoir which liquid-dominated hydrothermal reservoir is a type of geothermal reservoir that most widely used for power plant. The exploitation of mass and heat from the geothermal fluid will decrease the pressure in the reservoir over time. Therefore the pressure drop in the reservoir will have an impact on the formation of boiling zones or boiling will increase. The impacts are an increase in the fraction of steam, dryness, in the reservoir and with good vertical permeability will form a steam cap underlying the brine reservoir. The two- phase liquid dominated reservoir is sensitive to the porosity and difficult to assign average properties of the entire reservoir when there is boiling zone in some area of the reservoir. These paper showed successful development of two-phase liquid dominated geothermal reservoir and discussed the formation of steam cap above brine reservoir through numerical simulation for state natural conditions. The natural state modeling in steam cap shows a match with the conceptual model of the vapor-dominated developed. These paper also proofed the presence of transition zone, boiling zone, between steam cap and brine reservoir.
The rhetorical strategies to create incremental innovation in applied linguistics research articles

Rhetorical studies within research articles have received a growing concern among linguists worldwide. However, studies on this significant area to create incremental innovation are rarely found. Understanding this need has attracted the authors to conduct the present study by investigating rhetorical strategies authors use to create incremental innovation in their research articles and analyzing linguistic features used to create innovation for their current research. In an attempt to address these purposes, the present study analyzed 37 research article introductions (RAIs) from the disciplines of Applied Linguistics published in four reputable international journals (Q1) with the Scimago Journal Ranks (SJR) higher than 0,61. This study employed a newly designed framework and linguistic feature approaches from previous studies for the analysis. The results showed three rhetorical strategies to create incremental innovation in research articles. However, of these three, most authors tend to employ Strategy 2, Presenting the existing knowledge – and then – improving it in the present study, more than the other two strategies. Then, to realize incremental innovation, they employed six linguistic features, but of these six, two features (connective adverbs and phrases denoting examining a particular issue) appeared to be the most dominant in the present data.
Tabriz Intra-urban Spatial Disparities

To achieve sustainable urban development and values from social justice; it is essential that all citizens enjoy resources, facilities and life opportunities equally. Due to lack of a stable or systematic approach of measuring urban problems, disparity in environmental conditions or access to social and physical infrastructures is more obvious, especially in the cities of developing countries. In this article, a hybrid method is presented using urban indicators and geographical information system (GIS), as reliable identification tools and a criterion, to produce information related to policies in complex and multidimensional aspects of spatial disparities. His information could be used by the policy makers in order to inform them about where the first target is and in what proportion they should invest. In case study of Tabriz, this method indicates how the combination of urban indicators and GIS is a valuable tool for access of better management in resources towards balancing and spatial order in population and activities. The results of this study can help to apply reforming policies through better understanding of intra-urban disparities and optimal trace of resources. It can also help to identify poor households based on redistribution credit with the geographical component attractive to planners and decision makers.
Solid-Liquid Equilibrium Study of Binary System Saturated Fatty Acid in Short Chain Alcohols

Unsaturated fatty acids are potential to be used for preventing degenerative diseases and developing brain function in babies. Separation of unsaturated fatty acids from saturated fatty acids efficiently achieved by urea complexation fractionation method. It is considered to be the simplest, most efficient, and lowest cost method. This study aimed to optimize urea complexation for increasing PUFA concentrations by determining solid-liquid equilibrium data of saturated fatty acids in short chain alcohols. In this study, there were two types of short chain alcohol, methanol and ethanol, in various concentrations (99,7%; 95%; 88%; 76% w/w) towards the solubility of saturated fatty acids, palmitic and stearic acid (PA and SA). PA and SA dissolved in various concentration of methanol and ethanol to get homogeneous solutions. When solid SFA disappeared by heating the solution, or first formed by cooling the solution, the temperature was determined as the solid-liquid equilibrium temperature. The results showed that the best composition of solvent within high solubility level is ethanol 95% and methanol 99,7% over palmitic acid because it can dissolve at room temperature and below 0.01 mole fraction.
Combining Field Data and Computer Modeling to Improve Designs for Two Wet Detention Ponds in James City County, VA

This honors thesis extends five years of research by undergraduate geology students at the College of William and Mary, evaluating the performance of wet detention ponds in James City County, Virginia. In this study, field measured peak inflows, peak outflows, centroid lag times, and runoff constants from two ponds were compared to design predictions and state and local regulations. HydroCAD models of each site were utilized to explore design elements providing uncertainty in predictions of pond inflows and outflows. Modeling results were used to interpret field performance data from this study and provide recommendations for design improvement. Mulberry Place pond, designed using the rational runoff method, did not exhibit peak inflows, outflows, centroid lag times, or runoff coefficients consistent with design predictions. This pond also likely fails to reduce peak outflows of the 2 yr, 24 hr storm to pre-development values (state standard MS-19). Longhill Grove pond, designed with the SCS TR-55 method, did not perform in the field as designed with respect to peak outflows and centroid lag times. Both ponds failed to meet the local James City County standard requiring retention of the 1yr, 24 hr storm for 24 hours. Field performance problems at each site resulted from three major design issues: 1) uncertainty in predicted and actual curve numbers and runoff coefficients, creating large differences between predicted and actual inflows and even larger differences between prediction and actual outflows; 2) a simplified "kerplunk"� method for calculating 24 hour drawdown and orifice sizing, creating ponds that typically retain water for less than 12 hours; 3) pond volumes 2x and 2.5x smaller than needed to adequately reduce the effect of the first two design problems.
The Development of E-Handout Teaching Materials for the Sub-Concept of Structure and Function of Tissues in Plants

Learning in the 21st century is supported by mastery of technology. The utilization of technology in education can be implemented in the use of electronic teaching materials, one of which is E-Handout. The purpose of this study was to describe the needs analysis, validity and practicality of the results of the Development of E-Handout Teaching Materials for the Sub-Concept of Structure and Function of Tissues In Plants. This research is categorized as research and development (R&D) based on the 4D model. Data collection used teacher and students needs instruments, validity and practicality questionnaires. The research subjects were 3 experts and 12 students of class XI MIPA at SMA Negeri 1 Alalak. The results showed that first, the results of the needs analysis were "good" (77.83), meaning that E-Handout teaching materials need to be developed on the Sub-Concept of Structure and Function of Tissues in Plants. Second, E-Handout have a validity of "very valid" (88.45), meaning that E-Handout is very valid and in accordance with learning objectives, language, format and media. Third, the practicality results are "very good" (91.88), meaning that the E-Handout is very practical and easy to read by students. This shows that the E-Handout developed is valid and practical so that it can be used as teaching material as needed. The implication of the research results is that students can learn independently anytime and anywhere using E-Handout via laptop or smartphone.
Expectation Modifies the Representational Fidelity of Complex Visual Objects

Abstract Prediction has been shown to play a fundamental role in facilitating efficient perception of simple visual features such as orientation and motion, but it remains unclear whether expectations modulate neural representations of more complex stimuli. Here, we addressed this issue by characterising patterns of brain activity evoked by two-dimensional images of familiar, real-world objects which were either expected or unexpected based on a preceding cue. Participants (n = 30) viewed stimuli in rapid serial visual presentation (RSVP) streams which contained both high-fidelity and degraded (diffeomorphically warped) object images. Multivariate pattern analyses of electroencephalography (EEG) data were used to quantify and compare the degree of information represented in neural activity when stimuli were random (unpredictable), expected, or unexpected. Degraded images elicited reduced representational fidelity relative to high-fidelity images. However, degraded images were represented with improved fidelity when they were presented in expected relative to random sequence positions; and stimuli in unexpected sequence positions yielded reduced representational fidelity relative to random presentations. Most notably, neural responses to unexpected stimuli contained information pertaining to the expected (but not presented) stimulus. Debriefing at the conclusion of the experiment revealed that participants were not aware of the relationship between cue and target stimuli within the RSVP streams, suggesting that the differences in stimulus decoding between conditions arose in the absence of explicit predictive knowledge. Our findings extend fundamental understanding of how the brain detects and employs predictive relationships to modulate high-level visual perception.
Evaluation of Caspase-8 Level in Serum of Patients with Autoimmune Thyroid Disorders

Autoimmune thyroid diseases (AITDs), including Graves' disease and Hashimoto's thyroiditis, are characterized by lymphocytic infiltration of the thyroid and the production of thyroid autoantibodies. While the etiology of AITDs is still not fully understood, a combination of genetic susceptibility and environmental triggers is believed to contribute to the breakdown in immune tolerance. This study aimed to evaluate the levels of thyroid hormones (T3, T4, TSH), Anti-thyroid peroxidase Abs (Anti-TPO Abs), Anti-Thyroglobulin Abs (Anti-TG(, and apoptosis marker (Caspase-8 ) in Iraqi patients with AITDs compared to healthy controls. A total of 1000 patients participated in the study 820 were excluded from the study because it was non-immune thyroid disease, and 180 subjects were recruited, including 60 Graves’ disease patients, 60 HT patients, and 60 healthy controls. Serum levels of T3, T4, TSH, Anti-TPO Abs and Anti-TG, caspase 8, and inhibin were measured. T3 and T4 levels were significantly decreased in Hashimoto's thyroiditis patients and increased in Graves’ disease patients compared to controls. TSH was significantly elevated in Hashimoto's thyroiditis and reduced in Graves’ disease patients. Caspase-8 was significantly higher in Hashimoto's groups compared with the control group, and Significantly lower in Graves group compared with the control group. In conclusion, an altered balance in thyroid hormones, Anti-TPO Abs, Anti-TG, and apoptosis markers occurs in AITDs. Elevated caspase-8 suggests that increased apoptosis may contribute to thyroid damage in AITDs. Further research is needed to clarify the roles of these mediators in AITD pathogenesis.
Ruining, demolition and regeneration in urban space: Sketching the research problem

The paper is intended to examine fundamental research problems connected with two processes that currently feature in urban space: demolition and regeneration as well as relationships between them seen from the perspective of diverse conceptual and theoretical approaches debated in geographic urban studies. Regeneration understood as a sequence of planned actions is about the redevelopment of degraded urban areas. Its idea is to introduce spatial, economic, social, and cultural changes in these areas to restore their social attributes, such as: improved standard of living, sustainable positive relations among various user groups, improved comfort in using the areas, and elimination of the existing inequalities. Demolition of a city means destruction of its infrastructure leading to morphological, functional, social, and cultural transformations. Knowledge about the reasons, course and effects of demolition helps us decide what types of demolition best fit given circumstances and subsequently propose effective remedy measures. By identifying relationships between demolition and regeneration in contemporary cities we can learn more about both processes and, consequently, more efficiently modernise organisation of space and its arrangement to meet the needs and requirements of present and future users. In conclusion we propose research questions which delineate the direction of further interdisciplinary studies in this field.
