An approach of measuring velocity based on auto-correlation in a single frame for IEEE 802.11ad
Authors: Zhao Sudun , Liu Wei , Lei Jing , Lai Ke
Published: August 2022

In this letter, we propose a velocity measurement algorithm based on
auto-correlation in a single frame for IEEE 802.11ad. The periodicity of
the Golay sequences in the preamble is exploited in the algorithm to
estimate the time delay and achieve the velocity measurement at the same
time. The improved measuring accuracy is obtained as the effection of
noise is suppressed by designing and utilizing the auto-correlation
function.

Published: August 2022

Infraocclusion of a primary molar is a relatively common occurrence
which seldom leads to serious complications, particularly when the
succedaneous permanent tooth is present. Despite the relative
infrequency of unfavourable outcomes, an infraoccluded primary molar may
be associated with other dental anomalies, including hypodontia.
Om kollektiv mobilisering – en innledning
Authors: Ågotnes Gudmund , Larsen Anne Karin , Midtgård Inger Helen , Åkerblom Kristina Bakke
Published: August 2022

The primary objective of this book is to present, analyze and discuss forms of collective mobilization from theoretical, methodological and practical perspectives, set against recent societal developments. Our aim is to investigate how collective mobilization occurs and how it can be facilitated, particularly at local and regional levels, while treating 'the local' as connected to a wider context. We understand 'collective mobilization' as joint effort, often in the form of grassroots initiatives, directed at changing basic living conditions and experienced as significant for the participants involved. A central premise for this understanding is that the mobilization is initiated by something or someone - a person, an incident, a group - leading to action. 'Collective mobilization' is, as such, the way deliberate collaboration, alliances and communication work within a community.

In this first chapter we elaborate on this understanding of the term and phenomenon of 'collective mobilization' and present some specific and concise examples. We argue for the relevance of collective mobilization for different professions and actors before describing the structure of the book and the primary objectives of the respective chapters.
Bærekraftige lokalsamfunn gjennom medvirkning og kollektiv mobilisering? Erfaringer fra utfasing av områdesatsing i Ytre Arna og indre Laksevåg
Authors: Økland Mary Alice , Nordgreen Linda Cathrine , Blindheim Torben
Published: August 2022

This chapter describes how the municipality of Bergen has worked with area development in two (of five) relatively deprived areas, indre Laksevåg and Ytre Arna. Since 2012, these geographical areas have been included in a national program aimed at improving deprived areas, with a focus on both their inhabitants and physical infrastructure. The included areas were prioritized based on several years of mapping and research, confirming the importance of comprehensive and coherent area development. A methodology highlighting participation has been applied in the two areas, and selected specific methods are presented theoretically in this chapter. Dialogue and collaboration with residents and other actors in these areas are identified as essential approaches.

Subsequently, results achieved in collaboration with the local population are presented. Sustainability has been a key concept, first and foremost to strengthen the local communities we have worked in. This chapter describes how the program with area development in indre Laksevåg and Ytre Arna is phased out, and the process connected to this. Added to this, the chapter describes how the two areas is organized and how this is linked to collective mobilization, sustainability and capacity building.
Barn, bok og boller: Fra frivillig lokalsamfunnsarbeid med boksamling og formidling til offentlig bibliotekfilial i bydelen
Authors: Bareksten Berit
Published: August 2022

This chapter is about the collective mobilization and cooperation that emerged through the voluntary organization Initiativ:Laksevåg (I:L) and the establishment of the library and dissemination arena Barn, Bok & Boller (Children, Books and Buns) (BBB). How did I:L and BBB play alongside the area initiative for indre Laksevåg, the local cultural office and other cultural institutions, private actors, organizations and arenas in the local community, as well as partners in neighboring municipalities, in promoting the re-establishment of a public library through collective mobilization and community development?

The chapter highlights how grassroots mobilization can create lasting systemic change and contribute to increased participation and activity in a community. Ripple effects have led to the establishment of several arenas, which in turn have reached new groups in the population.
Kollektiv mobilisering, sosiale bevegelser og den norske velferdsstaten: Medhjelper eller motstander av «det offentlige»?
Authors: Ågotnes Gudmund , Barua Padmaja
Published: August 2022

This chapter discusses understandings of collective communities in relation to the current welfare system in Norway. Initially, the theoretical basis within 'Social Movements Theory', hereinafter referred to as SMT, is explained. SMT is the study and analysis of how social movements arise, and the significance they may have at local, national and international levels. Furthermore, SMT is distinctly interdisciplinary and is explained in the chapter on the basis of its historical development and division into various subcategories.

Reference is also made to how different directions within SMT, including different understandings of motives for collective communities, can shed light on a contemporary Norwegian welfare policy context. Divisions of responsibility between the public and the civil sphere form the basis for discussions about how the welfare state appears as a provider of premises for social movements in today's Norway. We ask questions about whether social movements in Norway can be said to be 'institutionalized', i.e., taking place within rather than in opposition to established political systems. Finally, we discuss the implications of understandings of social movements in today's Norway against what was initially emphasized as their foundation: an emancipatory function and potential.
Tilnærminger til kollektiv mobilisering innen samfunnsarbeid, sosialt entreprenørskap og folkehelsearbeid
Authors: Larsen Anne Karin , Ågotnes Gudmund , Agdal Rita
Published: August 2022

The COVID-19-pandemic and the United Nations' Sustainable Development Goals represent societal challenges that require novel solutions, not only from national governments, supranational organisations, local communities and individuals, but also in the form of cooperation across professional groups and social areas. Community work, social entrepreneurship and public health are all disciplines that deal with societal challenges characterised by complexity. They are not, consequently, preoccupied with specific, isolated service areas or sectors, nor can they be placed within them. As professional disciplines, they have different origins and trajectories, but share a focus on development, co-creation and collective mobilisation linked to social, health-related, and environmental conditions.

From the vantage point of the three disciplines, the chapter provides examples of how collective mobilisation can start both from state and supranational organisations, but also from individuals and local initiatives often based on specific events or oppressive conditions. Nevertheless, commonalities are to be found in how collective mobilisation is predicated on a willingness to cooperate and has an inherent goal of ensuring sustainable development leading to significant results for participants. Collaboration and sustainability serve as analytical turning points when we discuss whether methods aimed at achieving sustainable results are shared or different in the three disciplines. The chapter sheds light on the ways in which the disciplines complement each other and the roles they play as actors within the welfare state.
Metodar for kollektiv mobilisering i samfunnsarbeid i Noreg og Sverige
Authors: Midtgård Inger Helen , Turunen Päivi
Published: August 2022

This chapter is based on a qualitative study with an exploratory design and includes two data sources, a selection of method literature and an online questionnaire on use of methods among Norwegian and Swedish practitioners. The aim of this chapter is to discuss methods and challenges for collective mobilisation within community work by comparing methods used in Norway and Sweden. In total, 19 professionals and activists from three sectors of society (public, civic and private) participated in an online questionnaire. The participants had diverse occupational or academic backgrounds, engaged in social development and development work in multiple ways, from community development to public health work, youth work and voluntary work, in both urban and rural environments. The results of the study show a diversity of methods that can be used for collective mobilisation, including aims of dialogue, co-operation and strengthening co-creation. However, in Norway methods were used more systematically than in Sweden, where methods were more fragmented. The participating Swedes put focus on practical activities and participation, while the Norwegians emphasized their experiences of structured methods and adaptations to the selected purpose. The results also show that the practitioners did not put emphasis on collective mobilisation, but on participation, relationships, dialogue, co-operation, and co-creation. Our findings indicate that current societal challenges call for further development of methods for both social collectivisation and collective mobilisation, instead of individualisation.
Minoritetsorganisasjonen som arena for å motvirke negativ sosial kontroll i innvandrerfamilier
Authors: Ihle Ragnhild , Ibrahim Abdullahi Elmi
Published: August 2022

This chapter deals with how government expects minority organisations to work within their own communities to prevent or abolish cultural practises towards young people that lead to negative social control, lack of freedom, and agency in their lives. In several governmental action plans, minority organisations are encouraged to play an active role, induced by financial grants. In this way, minority organisations can be seen as «schools of democracy». They can also be seen as contributors to many forms of social capital because they offer both a bonding environment, a foundation for bridging, and a linking social capital. For several years, the Somali organisation TUSMO has applied for grants to implement measures like mentorship programmes and generational dialogue, to raise awareness and reduce negative social control. Through the incentives, they have raised their democratic competence, they have been able to connect the levels of social capital, and they have created an awareness in their own organisation through dialogue.

Authors: Vega Loyola José Javier
Published: August 2022

Se estudia la presencia en la ciudad de Lima de inicios del siglo XVII, de indios del “Nuevo Reyno de Granada”, a partir de la información registrada en el Padrón de indios de Lima de 1613, contrastada con información del Archivo Arzobispal del Lima y del Archivo General de la Nación. Se encontró que eran mayormente originarios de pueblos del actual territorio de Colombia, que emigraron primero a otros espacios del territorio virreinal peruano y luego a la ciudad de Lima. De acuerdo con el perfil poblacional elaborado, predominaron los varones con el 80% sobre el 20% de las mujeres; los jóvenes menores de 26 años con un 66.6%, sobre 33.3% de 26 o más, siendo las edades límites 16 y 50 años; y de acuerdo con su estado civil los solteros con 73.3%, casados 3% y viudos 6.6%. Referente a la actividad económica que realizaron el 46.6% se dedicaron al servicio doméstico, 26.6% a la sastrería, y en menor porcentaje a oficios como el de zapatero, calcetero, cardador y arriero. Participaron en la vida económica y social de la ciudad de Lima, algunos incluso involucrándose en el generalizado comercio de mercaderías de contrabando traídos del Asia. Respecto a preferencia matrimonial los pocos casados lo hicieron con indios de Chile y del Asia. Se concluye que los “indios del Nuevo Reyno de Granada”, fueron inmigrantes libres, predominantemente varones, jóvenes, solteros, dedicados al servicio doméstico y en menor porcentaje a algunas actividades artesanales.

Los retos a los que está sometida la educación superior vienen determinados por un entorno muy cambiante y difícilmente predictible. Este entorno que recibe el nombre de VUCA, por sus siglas en inglés, y que responde a los conceptos de Volátil, Incierto, Complejo y Ambiguo, representa de forma muy clara la dificultad que supone reconocer el entorno respecto a la toma de decisiones. Disponemos de información abundante, pero al mismo tiempo incierta e incompleta. En este contexto, los directivos deben gestionar equipos de trabajo, liderarlos y motivarlos para el cumplimiento de sus objetivos estratégicos. Ante este escenario, las instituciones de educación superior deben utilizar el mayor número posible de herramientas que permitan dar a conocer y formar a los directivos del futuro con base en competencias. En este trabajo se presenta una experiencia aplicada en la Universitat Oberta de Catalunya y que muestra los resultados preliminares de un programa de investigación que estudia el impacto de los simuladores empresariales en entornos específicos de la toma de decisiones. Así, en este programa piloto se ha utilizado una simulación de negocios, Fitness Gym, en el entorno de un trabajo final del grado de Administración de Empresas. Se exponen los objetivos de la simulación y el diseño realizado, vinculando el análisis con la literatura existente en este ámbito específico de la docencia aplicado al e-learning.
La gamificación como herramienta transversal de formación integral: experiencia Serious Game UFV
Authors: Puebla Sánchez Inmaculada
Published: August 2022

Uno de los desafíos que enfrentan los programas de educación en los negocios, es facilitar a los universitarios desarrollar un conjunto integral de habilidades y conocimientos que les permitan obtener excelentes resultados profesionales en el futuro. Al mismo tiempo, deben desarrollar sólidos valores humanos, así como habilidades personales y profesionales que les permitan cambiar la sociedad a un modelo con pensamiento sistémico. Las soluciones basadas en gamificación responden a estas necesidades: transversales, prácticas, holísticas, sistémicas, emprendedoras e innovadoras. El uso de simuladores basados en gamificación, permite a los universitarios comprender mejor los conceptos que son difíciles de explicar, como la inversión en publicidad adecuada para lograr cierto nivel de ventas de un producto/servicio, o el impacto de un cambio en el tipo de ventas de una empresa exportadora. El uso de simuladores es común en disciplinas individuales (ventas, mercado, finanzas, operaciones, RRHH), pero usualmente no se usan transversalmente para asegurar un conocimiento integral de todos los aspectos del negocio desde una perspectiva sistémica. Por ello se crea la necesidad de tener un Centro de Simulación Empresarial (CSE) desarrollador e integrador de dicha metodología y de la solución práctica. La propuesta definida a continuación es presentar los resultados de una experiencia real basada en la interacción entre: enfoque de casos reales, innovación a través del uso de simuladores y gamificación.

Can lay the foundation for construction. From the perspective of logistics, this paper makes an in-depth exploration of the uncertainty of production and customer demand in public system management, and gives a mathematical model of fuzzy constrained programming combined with the characteristics of the information cloud structure to solve the detailed aspects of the system at a higher level.
Necessarily the Old Riddle Necessary Connections and the Problem of Induction
Authors: Backmann Marius
Published: August 2022

In this paper, I will discuss accounts to solve the problem of induction by introducing necessary connections. The basic idea is this: if we know that there are necessary connections between properties F and G such that F -ness necessarily brings about G-ness, then we are justified to infer that all, including future or unobserved, F s will be Gs. To solve the problem of induction with ontology has been proposed by David Armstrong and Brian Ellis. In this paper, I will argue that these attempts to solve the problem of induction fail. Necessary connections fail to reliably imply the respective regularities for two main reasons: Firstly, according to an argument originally presented by Helen Beebee, the respective necessary connections might be time-limited, and hence do not warrant inferences about future cases. As I will discuss, arguments against the possibility or explanatory power of time-limited necessary connections fail. Secondly, even time-unlimited necessary connections do not entail strict or non-strict regularities, and nor do they allow inferences about individual cases, which is an important function of inductive reasoning. Moreover, the proposed solution to the problem of induction would only apply to a tiny minority of inductive inferences. I argue that most inductive inferences are not easily reducible to the proposed inference pattern, as the vast majority of everyday inductive inferences do not involve necessary connections between fundamental physical properties or essences.
Heat and Mass Transfer in a Vertical Channel Flow Through a Porous Medium in the Presence of Radiation
Authors: Guria M.
Published: August 2022

An analysis is made of heat and mass transfer in a three dimensional flow between two vertical porous plates through a porous medium. Analytical solutions have been obtained using the perturbation technique. The effect of non-dimensional parameters on velocity, temperature and concentration field are shown graphically. It is seen that the main flow velocity decreases with an increase in both the radiation parameter and Schmidt number but increases with an increase in the thermal Grashoff number, mass Grashoff number as well as the permeability parameter. Variations of the shear stress at the left plate are given in a tabular form. It is seen that the shear stress due to the primary flow at the left plate increases with an increase in the Reynolds number but decrease with an increase in the Schmidt number. With the increase of both the radiation parameter and Reynolds number the temperature decreases. The concentration field also decreases with an increase of the Schmidt number. Variations of mass flux at the left plate are given in tabular form. It is seen that the mass flux at the left plate increases with increase in both Schmidt number or Reynolds number.

Published: August 2022

In the present paper, trigonometric B-spline DQM is applied to get the approximated solution of coupled 2D non-linear Burgers’ equation. This technique, named modified cubic trigonometric B-spline DQM, has been used to obtain accurate and effective numerical approximations of the above-mentioned partial differential equation. For checking the compatibility of results, different types of test examples are discussed. A comparison is done between L2 and L∞ error norms with the previous, present results and with the exact solution. The resultant set of ODEs has been solved by employing the SSP RK 43 method. It is observed that the obtained results are improved compared to the previous numerical results in the literature.

UN REGISTRO DE “LA POST-HAVANA”: NOTAS SOBRE FICCIÓN Y GLOBALIZACIÓN EN LA AUTOPISTA: THE MOVIE DE JORGE ENRIQUE LAGE
Authors: Rubio Manzano Javier
Published: August 2022

This paper analyses Jorge Enrique Lage’s (1979) novel La autopista: The movie, published in 2014 in La Habana, in the context of the latest Cuban narrative and Caribbean science fiction. Many of Lage’s works explore the different possibilities of Cuba’s future, positing universes full of strange and novel elements that may -or may not- correspond to the future of the country, although their main intention is not to build a model society: these universes are immersed in chaos, in instability. Globalization enters his novels as an irremediable force, being the cause of the arrival of all these elements on the island.

Nigerian theatre in a digital era and environment
Authors:   Department of History and International Studies, Delta State University, Abraka, Nigeria, Imiti Aghogho Lucky
Published: August 2022

Theatre, the earliest form of entertainment and enlightenment in Nigeria, is becoming a ghost of itself as a result of its inability to take on the colouration of the times. Some scholars are of the view that there should be a revival of the theatre by establishing more theatre while it remains bonded to its functional root, the live stage, because of its uniqueness. This study examined the likelihood of this renaissance and its survival in the face of the deluge of other media of entertainment in a digitally advanced era and environment. The study relied on the Media Displacement Theory, MDT, which explains a paradigm shift in an individual's use of new media by discarding the preceding one. Using in-depth interviews and Focus Group Discussions, FGD, the study revealed that live theatre-going culture has become unpopular with the Nigerian audience as a result of digital technology and sundry circumstances in recent times, which include insecurity and the COVID-19 outbreak that negates public gathering. The paper advanced that Nigerian theatre cannot afford to remain glued to its roots in a technologically digitalised environment or society, but has to evolve.
Experimental Investigation of Throttleable H2O2 and Polypropylene Hybrid Rocket Motor
Authors: Li Meng-Che , Chang Chih-Shin , Wei Shih-Sin , Wu Jong-Shinn
Published: August 2022

This study experimentally investigated the propulsion performance of a swirling-type throttleable hybrid rocket motor using hydrogen peroxide and polypropylene. An in-house throttle valve consisted of a servomotor, and an industrial ball valve was integrated to instantaneously control the oxidizer mass flow rate. Several ground static hot-fire tests with fixed oxidizer mass flow rates of [Formula: see text] (100%) and [Formula: see text] (82%) and many step-varying oxidizer mass flow rates were performed to examine its propulsion performance. The hybrid rocket motor achieved an impressive sea-level [Formula: see text] of 240 s, an engine [Formula: see text] efficiency of more than 97%, and a thrust uncertainty of less than 5% when the oxidizer flow rate was fixed as [Formula: see text]. For the multiple-step hot-fire test results, the thrusts and chamber pressures were both found nearly proportional to the oxidizer mass flow rates with different proportionalities. The overall [Formula: see text] ratio of the tests is 5.61, which is hardly shifted, unlike most hybrid rocket data reported previously. In summary, the total impulse and thrust are both linear to total oxidizer mass consumption in the range of 50–100% of [Formula: see text]. This major finding would indeed broaden the application of hybrid rocket motors to future space technology.
Airfoil Morphed Leading-Edge Design for High-Lift Applications Using Genetic Algorithm
Authors: Colletti Christopher R. , Ansell Phillip J.
Published: August 2022

A genetic algorithm was developed for the optimal design of morphing airfoil leading-edge shapes to maximize airfoil [Formula: see text], while retaining a constant leading-edge arc length. Using a candidate slotted, natural laminar flow airfoil, an inviscid–viscous flow simulation program suite was used to evaluate a randomized population of airfoils during the design process at low-speed, high-lift flight conditions of a representative single-aisle commercial transport aircraft. The use of a continuous morphing strategy to perform treatment of the leading-edge geometry in high-lift scenarios, as opposed to leading-edge flap or slat elements, is envisaged as a means to mitigate surface discontinuities and retain laminar flow qualities of future airfoil sections in cruise conditions. By using different definitions of the objective cost function, multiple morphed airfoil designs were found through the genetic algorithm to create a library of possible designs aimed to purposefully alleviate the leading-edge stall tendencies of the baseline airfoil. Three morphed designs were validated through experimentation in a low-speed, open-return wind tunnel. Resulting data were used to verify that the leading-edge separation property of the baseline airfoil during stall was effectively alleviated with use of the morphed leading-edge geometries.
Time-Dependent Failure Possibility-Based Design Optimization by Using Kriging Model and Fuzzy Simulation
Authors: Jiang Xia , Lu Zhenzhou
Published: August 2022

Time-dependent failure possibility-based design optimization (T-PBDO) can minimize the general cost while meeting the failure possibility requirement of aircraft structure in the service life. The accuracy of the T-PBDO solution obtained by existing efficient methods may be problematic in the case of nonlinear performance functions or multiple minimum performance target points. To overcome this limitation, this paper proposes a new double-loop method based on the adaptive kriging (AK) model and fuzzy simulation (FS), referred to as DL-AK-FS, is used to efficiently solve T-PBDO. In DL-AK-FS, to replace the real constraint performance function for dealing with the time-dependent failure possibility (TDFP) constraint, the inner loop is to adaptively construct a single-loop kriging model of the constraint performance function in the FS candidate sample pool. The outer loop is to search the optimal design parameters by optimization algorithm. The kriging model is first built in an augmented space that is spanned by design parameters and fuzzy inputs, and then it is adaptively and timely updated during the optimization iteration. Moreover, the strategy of reducing the size of the FS candidate sample pool is adopted to further improve the efficiency of analyzing the inner TDFP while ensuring the accuracy of the optimization solution. The strategy of combining FS with the AK model can extend the engineering applicability of the DL-AK-FS in estimating the inner TDFP, which is not limited by the complexity of the time-dependent performance function. The optimization results show that the proposed DL-AK-FS method in this paper is efficient and accurate for solving T-PBDO.
High Order Wall-Modeled Large-Eddy Simulation on Mixed Unstructured Meshes
Authors: Wang Z. J.
Published: August 2022

In the present study, an algebraic equilibrium wall model previously developed for hexahedral elements is extended to handle mixed meshes including prismatic, tetrahedral, and pyramidal elements in the context of a discontinuous high-order method. This extension is needed for complex geometries, for which high-order mixed elements (e.g., tetrahedral and pyramidal elements) are often necessary near solid walls to avoid meshing challenges. Various design decisions are discussed to achieve the best performance on massively parallel CPU/GPU architectures for a production-level high-order large-eddy simulation solver based on the flux reconstruction/correction procedure via reconstruction method, hpMusic. The extension to other elements is first evaluated using a benchmark channel flow problem at various Reynolds numbers. After that, flow over the NASA high-lift Common Research Model (CRM-HL) from the 4th AIAA High-lift Prediction Workshop is computed to further test the new implementation. Computational results at the third- and fourth-order accuracies are compared with experimental data.
Optimal Clipping of Structural Subgrid Stress Closures for Large-Eddy Simulation
Authors: Prakash Aviral , Jansen Kenneth E. , Evans John A.
Published: August 2022

Structural subgrid stress models for large-eddy simulation often allow for backscatter of energy from unresolved to resolved turbulent scales, but excessive model backscatter can eventually result in numerical instability. A commonly employed strategy to overcome this issue is to set predicted subgrid stresses to zero in regions of model backscatter. This clipping procedure improves the stability of structural models, however, at the cost of reduced correlation between the predicted subgrid stresses and the exact subgrid stresses. In this paper, we propose an alternative strategy that removes model backscatter from model predictions through the solution of a constrained minimization problem. This procedure, which we refer to as optimal clipping, results in a parameter-free mixed model, and it yields predicted subgrid stresses in higher correlation with the exact subgrid stresses as compared with those attained with the traditional clipping procedure. We perform a series of a priori and a posteriori tests to investigate the impact of applying the traditional and optimal clipping procedures to Clark’s gradient subgrid stress model, and we observe that optimal clipping leads to a significant improvement in model predictions as compared to the traditional clipping procedure.

Water treatment plant (WTP) is essential for supplying water with the accepted quality to the consumer. There is a necessity to evaluate the performance of WTP for proper treatment of raw water. The present study aimed to evaluate the performance of Qandil WTP units, Erbil City, Iraq. For assessment the WTP units, water samples were collected from raw water, after clarification, after filtration, and storage tank. Removal efficiencies for the clarifiers, filtration unit, storage tank, and the whole WTP were calculated and presented. Obtained removal efficiencies for the sedimentation unit, filtration unit, after disinfection, and the entire Qandil WTP were 85.13 %, 90.50 %, 31.9, and 99.178 %, respectively. In addition, water quality index (WQI) for the WTP was studied. WQI assessment was made by testing 13 physicochemical water quality such as turbidity, pH, electrical conductivity (EC), total dissolved salts etc... It has been found that turbidity, electrical conductivity, total alkalinity, and total hardness have more influence on drinking water quality. WQI for Qandil WTP was 41.59 and it regarded as excellent level.

The present study was made with an attempt to produce yogurt by partial addition of different levels of soymilk to cow milk. Control was prepared with 100% cow milk and other samples prepared with cow milk and soymilk in the ratio of 95:5, 90:10, 85:15, 80:20, and 75:25 respectively. The control and different treatments of milk blends were analyzed for total solids and pH. The results found that the addition of soymilk leads to an increase of pH and total solids from 6.7, 11.94 % to 7.1 and 12.54 % for control and milk samples containing 25:75 levels of soymilk respectively. Yogurt samples were analyzed for some physicochemical analysis (pH, whey syneresis hardness) and organoleptic characteristics like (Appearance, flavor, body, texture acidity, and overall acceptability) during 14 days of storage at 4±1ºc. It was found that with increasing the levels of soymilk the syneresis decreased and the hardness was increased, the separated whey was (11.1 and 8.5 ml) and hardness of (6.5 and 19 gm cm-2) was obtained during 21 days of storage for control and sample containing 75:25 level. In general, the results of sensory properties as evaluated by the panelists indicates that the samples with increasing soymilk levels gained high scores of 13.8, 13.8 and 17.3   and low value of 21.0   and 11.2 in comparison to the results of the control sample which were recorded as 10.3, 7.8, 8.8, 28.0 and 13.0 for texture, body, appearance, flavor and acidity respectively during 14 days of storage.

Authors: QasMarrogy Ghassan A. , Fadhil Areen J.
Published: August 2022

IEEE 802.11 based Wireless Local Area Networks (WLANs) are becoming popular in home, enterprise and public access areas primarily due to their low cost, simplicity of installation and high data rates. While WLANs continue to be predominantly data centric, there is growing interest in using WLANs for voice and text data especially in enterprise markets. In this paper, a comprehensive analysis comparison to measure the delay, throughput packet loss and retransmission attempts was done to different scenarios using different trending wireless protocols such as 802.11n (2.4GHz, 5GHz), 802.11g, 802.11b, 802.11a while transferring low and high data load in FANET, with two major routing protocols AODV, and OLSR. As concluded in the result, recent wireless technology 802.11n with frequency band such of 2.4GHz can give better performance as they transfer higher data rates with longer distances and frequency band of 5GHz with higher data rate and less distance than 2.4GHz.

Published: August 2022

Background:

Vertebral artery stump syndrome (VASS) involves repeated acute ischemic stroke (AIS) in the posterior circulation following vertebral artery (VA) orifice occlusion. The presence of VA orifice occlusion makes endovascular thrombectomy (EVT) difficult to achieve and leads to posterior circulation stroke with unfavorable functional outcomes. Here, we report a case of endovascular VA orifice angioplasty for the right VA pseudo-occlusion to prevent AIS following VASS pathology.

Case Description:

In a 76-year-old man presenting with dizziness, angiography revealed right pseudo-occluded VA at the origin concomitant with the left VA occlusion. The posterior circulation depended on the right VA through collateral flow to the distal portion. Prophylactic endovascular VA angioplasty for the right pseudo-occluded VA at the orifice was achieved to prevent AIS with tandem lesions. In the present case, endovascular VA angioplasty can prevent acute embolic stroke in the posterior circulation following EVT-resistant VASS pathology.

Conclusion:

Clinicians should be aware that EVT is not easy in AIS following VASS due to access difficulties and the treatment strategy should be carefully considered.
Evolution of the Indian population through the ages
Authors: Iyer Anuradha Ramesh , Parvathi Venkatachalam Deepa
Published: August 2022

The Indian subcontinent is synonymous with increased genetic diversity essentially attributed to migratory forces. Many theories that provide different perspectives regarding the current nature of the Indian subpopulation have been proposed. Each of these theories is equally insightful albeit contradictory in nature. Thus, there is ambiguity in terms of tracing the course taken by individuals forming the Indian subpopulation. A comparative analysis of the pre-existing hierarchal caste system and primitive Europeans, matrilineal factors, and increased incidence of population bottlenecks gives an insight into plausible theories that could have led to infringement across the borders of the Indian subcontinent. The Aryan exodus forms the crux of various migratory theories along with analysis of ancient DNA and Y-chromosome which are indicative of external infusion into the Indian gene pool. Thus, this review is a retrospective analysis based on concrete evidence generated from studies undertaken to map the evolution of population in the Indian context.
