Numerical Solution of Inviscid and Viscous Flow Across NACA0010 Airfoil with different Angles of Attack
Authors: Mohammad Erfan Khodabakhshi  , Masoud Aryanpour
Published: September 2023

The role of the airfoil in all engineering fields is very important. Airfoil designs are utilized in various applications such as aircraft wings, helicopter rotor blades, sails, fans, and turbine compressors. In the case of aircraft, airfoils are accountable for generating lift force and determining if it is adequate for balancing the aircraft's weight, as well as determining the amount of drag force that should be applied to the body. They also play a vital role in optimizing blade performance, as well as the heat and operational efficiency of turbines. Airfoils are moving in the flow passing by them, and they show different responses based on many parameters such as whether the flow is smooth or turbulent, viscous or inviscid, flow velocity, angle of attack, multidimensionality of velocity components, etc. For aeronautics vehicles and wind turbines, a large number of studies have been conducted to analyze aerodynamic forces on two dimensional airfoils as well as flow phenomena associated with different Reynolds numbers. Main object of this research is to figure out the flow characteristics around the airfoil body and analyze aerodynamic performance of airfoil. In order to investigate the computational efficiency of flow models, numerical examination has been done for flow across NACA0010 airfoil by using 2D Computational Fluid Dynamics (CFD) solver, ANSYS FLUENT 18.0, at various angle of attack (0o to 13o) for inviscid flow and (-30o to 30o) for viscous flow. Lift and drag coefficients and C p for lower and upper airfoil surface and velocity diagram based on different angle of attack has been solved for the sample under two different flow regimes. The contours of velocity were simulated, and stall point was noticed from 13° angle of attack in inviscid flow and 24o in viscous flow. In the non-viscous state, lift coefficient and drag coefficient was higher, in comparison with viscous flow.

Herbal medications got from restorative plants are utilized by a larger part of individuals as a result of their security and less aftereffects, yet it isn’t totally a fact that natural items make no side impacts or poisonous impacts, they truly do convey gambles. Administrative specialists of various nations manage the quality and standard of home-grown drugs based on issues related with them, for example, spice drug collaboration, aftereffects, harmfulness and unfriendly impacts. The International Drug Monitoring Program of World Health Organization has made specific rules for home grown drugs assessment and quality check. The WHO has gone through different endeavors to improve natural medications with regards to their wellbeing and viability. The natural medication poisonousness emerges when the medication is utilized without legitimate signs, in enormous dosages, or with different medications, for longer span without discussion of a doctor, and made suitable.

Published: September 2023

Millets, both major and minor, are important source of human diet. They are rich in proteins, carbohydrates, fat, fiber, micro nutrients including vitamins and minerals. Production of millets increase every year as they have high capacity to withstand biotic and abiotic stresses. However, in recent times, they are subjected to all type of bacterial, viral infections and fungal diseases. Blast, downy mildew, ergot, grain mold, smut, rust, bacterial leaf strike, bacterial leaf spot, Maize stripe virus (MStV-S), Maize streak virus, Maize mosaic virus (MMV-S) are common among all millets. Integrated crop management and pest control through agronomic cultural practices, use of resistant tolerant cultivars, chemical and biological control measures reduce the spread of diseases leading to high crop yield.

Published: September 2023

Physical therapy and Sujok have been proved to be safe and effective in osteoarthritis treatment as two major non operative methods. Only a little study has been focused on the functions of these methods comparing the effectiveness of su-jok, su joke + physical therapy and physical therapy on knee osteoarthritis patients. A random sample of 90 adult patients of knee OA aged between 18 to 60 years, (30 from each treatment) Sujok, Sujok + physical therapy and Physical therapy were taken for the comparison of effectiveness of all these treatments on knee osteoarthritis from the Ahmedabad city of India. Data was collected in the period of September 2022 to November 2022. When using an ANOVA with repeated measures with a Greenhouse-Geisser correction, the mean scores for pains after physical therapy sessions were statistically significantly different (F(3.119, 90.460) = 38.405, p < 0.0005). Post hoc analysis with a Bonferroni adjustment revealed that pain was statistically significantly decreased from after day 3 of continuous physical therapy treatment. While in Sujok and Sujok + Physical therapy the pain decreased significantly after 1st day but increased drastically after day 6.

Correlation Between COSMIC Rayn Intensity and Geomagnetic Activity Indices
Authors: Mudasir Ayoub  , G. N Singh
Published: September 2023

This study conducts an extensive analysis to explore the correlation between the monthly average cosmic ray intensity (CRI) and indicators of geomagnetic activity, primarily focusing on the Ap and Kp indices. The study covers two distinct time intervals, 1996-2008 and 2009-2019. By analyzing the correlation between CRI and geomagnetic indices, we constructed linear graphs depicting their associations. The results consistently reveal a noticeable inverse correlation between monthly average CRI and the Ap index. Correlation coefficients were computed to quantify these relationships using established statistical methods. Between 1996 and 2008, a strong negative correlation of -0.89 was observed between CRI and the Ap index. Similarly, during 2009-2019, a significant negative correlation of -0.39 was noted. The monthly average CRI exhibited a negative correlation of -0.72 with the Kp index during 1996-2008, and a more pronounced negative correlation of -0.70 during 2009-2019. These findings underscore the intricate interplay between cosmic ray intensity and geomagnetic activity, offering insights into the broader understanding of space weather phenomenon
On positionalities in research with international students
Authors: Spangler Vera
Published: September 2023

In this paper, I argue that if we want to further strengthen the current direction towards more innovative and critical methodological research designs in research with international students, we must engage more deeply and meaningfully with our own positionalities as researchers. In order to build a more honourable and accurate portrayal of our participants – international students, we must begin to acknowledge the dynamic multiplicity and situational understandings of positionalities and move away from monolithic and ascriptive presentation statements (e.g., nationality, age, gender). A critical appreciation of positionality helps us to develop a reflexivity that enhances the methodological strength of our research approaches and, considering the lack of nuance in many conceptions of international students, acquire information from and about them that (more) faithfully represent their experiences and worlds. This, hopefully, allows us to counter inequalities in practice and move away from positions of deficit and problematic discourses and assumptions.

VIRGENCICA, VIRGENCICA!: FORMAS DE VIDA QUE RESISTEN E INSISTEN PESE AL IMPULSO HOMOGENEIZADOR DE LA ARQUITECTURA MODERNA
Authors: García Ruiz María , Soto Calderón Andrea
Published: September 2023

El presente artículo tiene por objeto proponer un análisis crítico del proceso de regeneración urbana que supuso la edificación del conjunto residencial de emergencia denominado La Virgencica, a través de una práctica artística, como metodología alternativa para generar conocimiento relevante sobre las prácticas del habitar. Metodología que hace posible ahondar en las reflexiones en torno a los procesos de normalización espacial, pero sobre todo pensar en prácticas de resistencia a esos procesos de regularización: desde el cuidado de los vínculos que hace posible la existencia de una comunidad hasta las diversas maneras de apropiarse del espacio que pueden desbordar los aparatos arquitectónicos. Si bien toda producción del espacio urbano está estrechamente vinculada con unos modos específicos de disciplinar las formas de vida, nos interesa atender al potencial crítico de aquellas formas de vida que no se sujetan a sus modos de estandarización. Consideramos que la investigación artística tiene un rendimiento particular para recuperar la memoria del lugar y pensar en qué sentidos se pueden desarrollar metodologías para habitar insubordinadamente las formas segregadoras del presente.
LA TRAZA DE UNA GIROLA EN LA TORRE DEL ÁNGEL DE LA CATEDRAL DE CUENCA (ESPAÑA)
Authors: Gutiérrez-Hernández Alexandra M.
Published: September 2023

Las trazas de arquitectura, que hoy llamaríamos planos, ayudaban al maestro a reflejar todo su ingenio e inventiva para “vender” su proyecto al mecenas correspondiente, o para defender su posición en caso de pleito o conflicto por la obra en cuestión. Una planta de iglesia de tres naves con girola, en principio podría hacer referencia a cualquiera de las dos cuestiones arriba planteadas y no supondría mayor misterio. Sin embargo, si esta traza no se localiza en un pleito o contrato, sino que se encuentra incisa sobre los paramentos de una construcción a la que, inicialmente, no parece estar haciendo referencia, la trama se complica un poco más. En esta última línea se enmarca la traza de una iglesia de tres naves con girola localizada en la pared de la Torre del Ángel de la catedral de Cuenca (España), que ha ocasionado un gran interés, así como numerosas dudas acerca de su realización. Cuando se hizo, quién la realizó y por qué, son las cuestiones que han suscitado mayor preocupación. Esta muchas veces ha derivado en la necesidad de buscar la autoría del diseño, o su relación con algún edificio concreto ya construido, dejando de lado, quizá la propia traza. En este trabajo, trataremos de poner en valor, precisamente, este dibujo, sin olvidarnos de aquellas teorías vertidas al respecto, pero, focalizando el interés en el propio diseño.

This study is of believe that Illegal acts and discerning sand excavation/mining has become arisk to the ambiances. While theresearchrelied on personal geological observation on the mining sites, qualitative data were used from secondary literature. Using Agila’s river and coastal mining sites as a case study, the study revealed that it sparks to diversifications in river channels ways, physical ecosystem and food webs. As well it speeds up the river’scurrent and eventually eroding the river banks. Destroying the soil profile and removing the flora reduces the population of animals and eliminates habitat both the surface and subsurface resources. Sand dunes has played a vital aspect role in stoppage against heavy storms, erosion causes by some agents of transportations like winds, waves or floods. Numerous tiny habitants that are a component of the marine and coastal food chain and whose removal would pose some hazards to some other species rely on them for existence. The water tables in the surrounding areas decline as a result of sand mining, drying out the drinking water wells on the river embankments. Turbidity rises at the mining site as also the aquifers near the shore are affected by saline water intrusion. Sand mined areas loose scenic beauty, it emits radiation reliant on the component minerals, dust pollution, emits vibration/noise and it damages roads and some infrastructures. This researchinspected and reviewed the sand mining impacts on river, dune, marine, hydrological, biological and sociological environments with some case studies of the study area.

Authors: Prusov Dmitry , Dubova Svetlana
Published: September 2023

Based on the analysis of the fundamental impact of transport infrastructure, the city and the agglomeration are increasingly interpreted as a set of historically composed residential and industrial districts formed in the areas of interchanges of different modes of transport. On the example of the City of Kyiv, the modeling of passenger flows in agglomerations of large developing cities is considered, in order to implement the provisions of a modern urban environment, based on transport analysis of the urban area, with further forecasting of passenger flows on the street-road network and choice of main types of citywide passenger transport in the city. Based on the calculation of the population and passenger formation of transport areas, a model of the city's transport infrastructure is represented, the distribution of passenger traffic by modes of transport is estimated. The results of experimental studies of the intensity of existing passenger flows and models of their definition in the agglomeration of the most valuable city are determined. And the ways to solve the problems of conflict between the city and transport are proposed.

Decentralization in Blockchain: Reconsidering Change Management Theories
Authors: Vendette Sebastien , Thundiyil Tomas G.
Published: September 2023

This paper explores the implications of blockchain technology's decentralization for traditional change management theories. As digital technologies continue to disrupt organizational structures, blockchain stands out with its unique feature of decentralization, challenging the centralized premise inherent in many existing change management theories. While influential and widely applied, these theories are largely predicated on certain fundamental assumptions about organizations and the nature of change, often assuming a centralized structure where authority and decision-making are concentrated at the top. However, with its inherent decentralization, blockchain technology democratizes decision-making and authority, disrupting traditional power dynamics and posing significant challenges to these assumptions. The present paper aims to address the gap in the current literature by exploring how blockchain's decentralization challenges and expands our current theories of change management wherein we propose theoretical adjustments and potential new constructs for change management. By doing so, we contribute to the evolving discourse on change management in the digital age and illuminate the transformative potential of blockchain’s decentralization and its implications for our understanding and practice of managing organizational change.
Foraminiferal population dynamics on elevated plastic substrates and in sediments at 4000 m in the Eastern Pacific
Authors: Burkett AM , Rathburn AE , Gonzalez Acevedo A , Gonzalez Acevedo C , Ezpeleta J
Published: September 2023

Although plastics are becoming more prevalent, even in the far reaches of the deep sea, the influence of these novel attachment surfaces has yet to be systematically studied regarding the ecology and distribution patterns of attached fauna. Herein, we report the abundances and vertical distribution patterns of epibenthic foraminifera living on plastics after 2 yr on the seafloor at 4000 m water depth and compare these populations with those of nearby naturally occurring substrates and their surrounding sediments. After 2 yr, 239 foraminifera were found attached to 4 Seafloor Epibenthic Attachment Cubes (SEA3s). Dominant taxa included Cibicidoides wuellerstorfi var. lobatulus, Pyrgoella sp., and arborescent foraminifera. Variations in colonization height and abundance between plastic types were observed, but no clear drivers of these patterns can be ascertained from this study. Foraminiferal populations from elevated substrates and the nearby sediment cores showed no significant overlap in populations, suggesting that foraminifera colonizing SEA3s did not originate from surrounding sediments and likely recruited from other elevated substrates common in the area (e.g. glass sponges). This study demonstrates that plastics serve as hard substrates which deep-sea foraminifera inhabit and that plastics may persist for extended periods of time, potentially altering ecosystem compositions in environments dominated by soft sediments. There is a significant difference between colonizing epifaunal and sediment populations, which raises interesting questions about colonization and distribution processes in deep bathyal and abyssal environments. Epibenthic foraminifera attached to elevated substrates may be underrepresented in the sedimentary record through preservation and sampling biases.

Neolitik dönemde tarımın keşfedilmesiyle birlikte kültür altına alınan ve medeniyetlerin gelişmesinde son derece önemli bir paya sahip olan kenevir, zengin lif içeriğiyle pek çok alanda kullanılabilmesine rağmen THC oranı yüksek olan kenevir türünün (marijuana) yasa dışı uyuşturucu olarak kullanılması sebebiyle Dünya’nın en şüpheyle yaklaşılan bitkisi haline gelmiştir. Endüstriyel kenevir olarak da bilinen kenevir türü (hemp) ekolojik olarak çevreye olumlu etkilerinden ve yüksek ekonomik getirisinden dolayı ülkemizde bazı alanlarda izinli olarak yetiştirilmektedir. Kenevirin ekonomik getirisi ve 25.000 farklı ürünün ham maddesi olması dolayısıyla ülkemizde kenevir yetiştiriciliği teşvik edilmelidir. Bu çalışmada, Samsun, Amasya ve Tokat illerinde kenevir yetiştiriciliği için uygun sahaların tespit edilmesi amaçlanmıştır. Bu amaç doğrultusunda bitkinin ekolojik istekleriyle sahanın ekolojik koşulları Best-worst yöntemiyle analiz edilmiş ve sonuçlar haritalanarak çalışma sahasındaki tarım alanlarının %22-29’unun kenevir tarımına uygun olduğu tespit edilmiştir. Bu çalışma, pek çok açıdan sürdürülebilirliğe katkısı olacak kenevirin tanıtılmasını ve yetiştiriciliğinin yaygınlaşmasını sağlamak açısından önemlidir.

This paper explores the significance of special teams, particularly powerplay, in ice hockey. Despite the commonly held perception of their importance, little research has examined the impact of powerplay and penalty kill performance on overall team success. The paper uses several seasons of NHL data to characterize goal-scoring and manpower opportunities, and perform analysis from several perspectives. The results indicate that individual even strength goals and powerplay goals have similar value, but the larger share of even strength goals scored over a season makes even strength play a more important contributor to team success. The paper also finds a high correlation between teams that perform above/below average during even strength and powerplay. This study provides insights into the dynamics of ice hockey gameplay and the role of special teams in determining team success.

Today's IOT (Internet Of Things) technology is very popular, with interactions between objects and humans can communicate with each other or objects with objects can also communicate with each other, as well as the application to security in anticipating unexpected fires, or monitoring the situation using early detection sensors, so a smoke detection prototype is made using the MQ-2 sensor and milk detection using the DS18B20 sensor. This detection tool uses Arduino Mega, (MQ-2) and DS18B20, then if there is a fire to extinguish using a Selenoid Valve tool used for water dispensing valves, then to neutralize the air using an Exhaust Fan, this Exhaust Fan is also used to neutralize the air in the room even though there is no smoke detected, The point is to maintain the room temperature so that it is not impermeable and hot in the room, then don't forget also for the notification using two SIM800L notification systems for SMS and NODE MCU ESP32, for NODE MCU ESP32 this uses a Wireless Connection, the two notifications work alternately if one of the notification tools does not work. The method used in this research uses the experimental method. This tool is tested and implemented on a square 50 x 50 cm of hardware and provides the expected and appropriate results. The temperature will be detected above 50°C (Celsius).

Patients who require blood from rare blood group donors present great challenges even to the most advanced healthcare delivery system. It is most challenging to supply blood for a patient with an antibody to an antigen of high prevalence. The blood donor lacking the corresponding antigen would have an occurrence rate of less than one in 1,000. The International Rare Donor Panel was established in 1965, but since then there has been gross underrepresentation of South Asian countries, including India. There are several challenges to starting a rare blood group donor program in India that include technical, logistical, and administrative limitations. But the main limiting factors are poor availability of trained resources, lack of awareness, absence of antibody screening, inadequate number of laboratories with blood group genotyping facilities, and the decentralized nature of blood transfusion services. Despite that, there were several rare blood groups identified by Indian immunohematologists in the recent past. Recently, a transfusion genomic group has been established in collaboration with the clinical transfusion medicine specialists in India under the GUaRDIAN (Genomics for Understanding Rare Disease in India Alliance Network) initiative to address the domain of rare blood group genomics. Similarly, the National Institute of Immunohematology, Mumbai under the directive of the ICMR (Indian Council of Medical Research) has taken a step to start the RDRI (Rare Donor Registry of India). In this context, we explore the current challenges of setting-up a rare blood group registry in India and future goals from a developing nation’s perspective.
The relations between constipation and characteristics of intestinal morphologies by colonoscopy
Authors: Xu Yuting , Xiao Qili
Published: September 2023

Background

Constipation is commonly diagnosed throughout the world, and it is typically associated with various factors. However, data on the characteristics of intestinal morphologies linked with constipation are scarce. We examined the association between the characteristics of different intestinal morphologies and constipation.

Patients and methods

Between March 2020 and February 2021, we enrolled 510 patients from the Affiliated Zhongshan Hospital of Guangzhou University of Chinese Medicine into two groups: 260 in the constipation group and 250 in the control group. Of these patients, intestinal morphology characteristics obtained via colonoscopy were compared and analyzed.

Results

There were meaningful differences between the cohorts based on the intestinal morphology characteristics of tortuousness (p < 0.001) and dissociation (p < 0.001). In addition, a significant difference in characteristics was determined for either both intestinal morphologies (p < 0.001) or only tortuousness without any other conditions (p=0.015), but there was no significant difference between the two groups with respect to only dissociation without any other conditions (p = 0.077). A subgroup analysis was performed on statistically significant variables—gender (p < 0.001), age (p = 0.002), and operation time (p < 0.001)—and the results showed that regardless of the subgroup analysis, there was a statistically significant difference in tortuousness between the two groups. In addition, there were significantly differences in dissociation between the groups for elderly men and those with a longer operation time.

Conclusion

Compared with the general population, people with the intestinal morphologies of dissociation and, in particular, tortuousness seem to experience constipation more frequently.

A multitude of alterations in the old immune system impair its functional integrity. Closely related, older individuals show, for example, a reduced responsiveness to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccines. However, systematic strategies to specifically improve the efficacy of vaccines in the old are missing or limited to simple approaches like increasing the antigen concentration or injection frequencies. We here asked whether the intrinsic, trimeric structure of the SARS-CoV-2 spike (S) antigen and/or a DNA- or protein-based antigen delivery platform affects priming of functional antibody responses particularly in old mice. The used S-antigens were primarily defined by the presence/absence of the membrane-anchoring TM domain and the closely interlinked formation/non-formation of a trimeric structure of the receptor binding domain (S-RBD). Among others, we generated vectors expressing prefusion-stabilized, cell-associated (TM+) trimeric “S2-P” or secreted (TM−) monomeric “S6-PΔTM” antigens. These proteins were produced from vector-transfected HEK-293T cells under mild conditions by Strep-tag purification, revealing that cell-associated but not secreted S proteins tightly bound Hsp73 and Grp78 chaperones. We showed that both, TM-deficient S6-PΔTM and full-length S2-P antigens elicited very similar S-RBD-specific antibody titers and pseudovirus neutralization activities in young (2–3 months) mice through homologous DNA-prime/DNA-boost or protein-prime/protein-boost vaccination. The trimeric S2-P antigen induced high S-RBD-specific antibody responses in old (23-24 months) mice through DNA-prime/DNA-boost vaccination. Unexpectedly, the monomeric S6-PΔTM antigen induced very low S-RBD-specific antibody titers in old mice through homologous DNA-prime/DNA-boost or protein-prime/protein-boost vaccination. However, old mice efficiently elicited an S-RBD-specific antibody response after heterologous DNA-prime/protein-boost immunization with the S6-PΔTM antigen, and antibody titers even reached similar levels and neutralizing activities as in young mice and also cross-reacted with different S-variants of concern. The old immune system thus distinguished between trimeric and monomeric S protein conformations: it remained antigen responsive to the trimeric S2-P antigen, and a simple change in the vaccine delivery regimen was sufficient to unleash its reactivity to the monomeric S6-PΔTM antigen. This clearly shows that both the antigen structure and the delivery platform are crucial to efficiently prime humoral immune responses in old mice and might be relevant for designing “age-adapted” vaccine strategies.
A clash on the Toll pathway: competitive action between pesticides and zymosan A on components of innate immunity in Apis mellifera

Published: September 2023

Background

The immune system of honeybees includes multiple pathways that may be affected by pesticide exposure decreasing the immune competencies of bees and increasing their susceptibility to diseases like the fungal Nosema spp. infection, which is detected in collapsed colonies.

Methods

To better understand the effect of the co-presence of multiple pesticides that interact with bees like imidacloprid and amitraz, we evaluated the expression of immune-related genes in honeybee hemocytes.

Results

Imidacloprid, amitraz, and the immune activator, zymosan A, mainly affect the gene expression in the Toll pathway.

Discussion

Imidacloprid, amitraz, and zymosan A have a synergistic or an antagonistic relationship on gene expression depending on the level of immune signaling. The presence of multiple risk factors like pesticides and pathogens requires the assessment of their complex interaction, which has differential effects on the innate immunity of honeybees as seen in this study.
