Authors: Lytvynenko M.V.
Published: February 2023

Women with immunodeficiency conditions are a separate cohort of patients who need the close attention of doctors and social workers. The aim of the study was to determine the distribution of CD68 and CD3 immune cells in the cervix of women with infectious and non-infectious immunodeficiency, namely, HIV infection, chronic alcoholism and their combination. Research groups were formed based on the results of autopsies of 100 women of reproductive age, 25 cases in each group: a group with HIV infection, a group with chronic alcoholism, a group with a combination of HIV infection and alcoholism, and a comparison group. An immunohistochemical study was performed with monoclonal antibodies to CD68 and CD3. During the research it was established that the CD68 and CD3 immune cells distribution in the cervix of women with infectious and non-infectious immunodeficiency is characterized by a decrease in CD68 in the epithelial layer of both groups of HIV-infected women (up to (1.06±0.13) cells/mm2 for the group without alcoholism and up to (1.09±0.11) cells/mm2 in the group in combination with alcoholism), while in the group of women who abuse alcohol, this indicator increased to (1.96±0.15) cells/mm2 (p<0.05). In the stroma, the accumulation of CD68-positive cells tends to decrease in all groups. The dynamics of the distribution of CD3-positive cells in different zones of the cervix is characterized by their decrease in the epithelium of HIV-infected groups, while in women who abuse alcohol their number is increased (p<0.05) to (3.86±0.14) cells/mm2. Simultaneously, stroma infiltration of all three groups with HIV is characterized by a significant increase in CD3-positive cells to (8.13±0.79), (9.89±0.57) and (9.04±0.75) cells/mm2 for groups with HIV infection, abuse alcohol and the combination of chronic alcoholism and HIV infection, respectively (p<0.05). Based on the results of the study, it can be concluded that the CD68 and CD3 immune cells distribution in the cervix of women with infectious and non-infectious immunodeficiency is characterized by variability depending on the nature of the immunodeficiency.

Reforms for Another Planet: The Global Learning Crisis, Political Drivers and Expert Views on Egypt’s Edu 2.0
Authors: Sobhy Hania
Published: February 2023

This study examines four key reform policies and programs of the Indian education system: DPEP (1994), SSA (2000), RTE (2010) and NEP (2020). Each of these has a rich and nuanced body of research to which our study contributes a unique tracing of the key ideas, debates, and stakeholders. This longue durée of reform will shed light on the histories of current reform options and if they will indeed meet the call of the times to address the learning crisis. We use the political settlements approach to understand the contestation of ideas and actors which finally determine the policy design and the implementation strategies. We unpack the iterative dynamics between ideas and actors to highlight why our reform design looks the way it does and what kind of spaces exist for transformative change particularly to ensure learning.
O Poder Executivo brasileiro e os abusos à liberdade de expressão no tocante à igualdade de gênero: anti-conduta e controle judicial
Authors: Ribeiro Antonia
Published: February 2023

This study aimed to analyze the effects and anti-conduct of the Brazilian executive in relation to the issue of gender and equity, from the perspective of freedom of expression. It is bibliographical research with a qualitative approach, where primary and secondary research sources were used. To delve into this dense universe, the work presented brief theoretical aspects of gender discourse as well as inverse and controversial behaviors of the Brazilian chief executive (2019-2022) and his ministries. In this perspective, the contextualization of women was unraveled from angles of history, taking as a premise the way in which gender violence permeates generations, in a cyclical repetition, and how populist governments have deconstructed the perspective of equity and rights of women, contrary to their duty to regulate and promote constitutional public policies with gender equity. Brazilian institutions, within their constitutional missions, use the regulatory power-duty, within the system of checks and balances, to denounce behaviors that violate Brazilian constitutional values. In this way, it is concluded that, thanks to the democratic regime and the judicial control of the acts of the powers, we can see the condemnation of a president of the republic, as a political agent and to the detriment of his lines that seek to deconstruct the political rights conquered. for the women. In addition to being didactic, the sentence is a thermometer showing that the institutions have matured over time and that the primacy of equality is not only material, but a premise of the Brazilian democratic State.

Structure of the space of GL4 (Z2)-coinvariants Z2 ⊗ GL4 (Z2) P H∗ (Z42,Z2) in some generic degrees and its application
Authors: Võ Phúc Đặng
Published: February 2023

 Let $A$ denote the Steenrod algebra at the prime 2 and let $k = \mathbb Z_2.$ A very difficult problem in algebraic topology is to determine a minimal set of $A$-generators for the polynomial ring $P_q = k[x_1, \ldots, x_q] = H^{*}(k^{q}, k)$ on $q$ generators $x_1, \ldots, x_q$ with $|x_1|= |x_2| = \cdots = |x_q| =  1.$ Equivalently, one can write down explicitly a basis for the cohit space $\pmb{Q}^{q} := k\otimes_{A} P_q$ in each non-negative degree $n.$ This subject, which has now a long history, is the content of the classical "hit problem" proposed in [Abstracts Papers Presented Am. Math. Soc.  \textbf{833} (1987), 55-89]. Furthermore, it is closely related to the $q$-th transfer homomorphism $Tr_q^{A}$ constructed by William Singer in [Math. Z. \textbf{202} (1989), 493-523]. This $Tr_q^{A}$ passes from the space of $G(q)$-coinvariant $k\otimes _{G(q)} P_A((P_q)_n^{*})$ of $\pmb{Q}^{q}$ to the $k$-cohomology group of the Steenrod algebra, ${\rm Ext}_{A}^{q, q+n}(k, k),$ where $G(q)$ denotes the general linear group of degree $q$ over the field $k,$ whereas $P_A((P_q)_n^{*})$ is the primitive part of $(P_q)^{*}_n$ under the action of $A.$ Particularly, Singer conjectured that $Tr_q^{A}$ is a monomorphism, but this remains unanswered for all $q\geq 4.$ Accordingly, the aim of the present study is to deal with the Singer conjecture for rank 4 in some certain internal degrees. Specifically, by the usage of the techniques of the hit problem in four variables, we explicitly determine the structure of $k\otimes _{G(4)} P_A((P_4)_{n}^{*})$ in some generic degrees $n.$ Then, applying these results and a representation of $Tr_4^{A}$ via the lambda algebra, we state that Singer's conjecture is true for rank $q = 4$ in respective degrees $n.$ This has contributed to the final proof of Singer's conjecture in the rank 4 case.
Pneumatic Exoskeleton Joint with a Self-Supporting Air Tank and Stiffness Modulation: Design, Modeling, and Experimental Evaluation
Authors: Miskovic Luka , Dežman Miha , Petrič Tadej
Published: February 2023

Electromechanical variable stiffness actuators (VSA) can store and reuse different amounts of energy in the elastic element by varying the stiffness, but they are typically heavy for use in exoskeletons because they require more than one motor. At the same time, the use of pneumatic actuators in exoskeletons is suitable due to their high power-to-weight ratio and inherent compliance, where stiffness varies with applied pressure. However, the required air supply often compromises the portability of such systems. In this paper, a novel pneumatic exoskeleton joint mechanism (PEJM) is proposed that uses a pneumatic artificial muscle (PAM) as an air tank and a pneumatic cylinder to store and reuse energy and thus generate torque. The main innovation is that the PAM is independent of an external air supply; instead, compressed air from a cylinder is used to inflate the PAM. This is achieved by timely control of three air solenoid valves and air accumulation. Variable stiffness is achieved in two ways: by changing the pressure in the pneumatic cylinder and by contracting the PAM's length. The mechanism and method of stiffness modulation are first described analytically and then evaluated experimentally on an experimental platform where various functions, temperature effects and leakage tests are investigated. The results show satisfactory performance and validate the theoretical concepts.
Performance Analysis of Spectral Amplitude Coding Methods in Fiber Optical Communication System
Authors: Abusale Wahhab Abdulrazzaq , Karabulut Muhammet Ali , Ilhan Haci
Published: February 2023

 This study analyzes optical code division multiplexed access system coding with two different types of spectral amplitude coding (SAC): Double Weight (DW) codes and Multiple Diagonal (MD) codes. These two encoding types differ in code structure and channel bandwidth length (the number of wavelengths representing the channel's bandwidth), as well as Q-Factor, BER, and MAI values. This study analyzes systems with different number of users over single-mode optical fiber and presents a comparison of both. DW codes have a shorter length code than MD codes, and although this technique can generate unique code words for each user, it will break the system using MD encoding. This is another reason to increase bandwidth for MD codes.

Published: February 2023

The design and development of sub-Terahertz (THz) communication systems entail the need for new channel models that can precisely predict channel characteristics at such frequencies (>100 GHz) in outdoor and dynamic environments. This work proposes a novel hybrid-stochastic ultra-wideband channel model for sub-THz bands, developed within the framework of a class of spatio-temporal stochastic processes called ambit-process. The proposed model is capable of supporting bandwidths of upto 10 GHz. The spatio-temporal evolution of the ambit framework allows for a reasonably accurate and tractable characterization of the fading statistics and multipath propagation of a cellular channel with good spatial consistency. We leverage a recently proposed low-complexity ambit-process based channel simulation algorithm with necessary modifications to study key features of the outdoor sub-THz channel like associated diffused scattering, molecular absorption, spatio-temporal correlations, and consistency between the time-evolving delay and Doppler of the multipaths. Simulation results on path loss, delay spread, and channel correlation indicate that the ambit model accurately captures the typicalities of an urban microcellular sub-THz channel and agrees well with the measurement results reported in the literature. 
Estimation of Dynamical Noise Power in Unknown Systems

Published: February 2023

Noise can be modeled as a sequence of random variables defined on a probability space that may add to a given dynamical system T that is a map on a phase space. In the nontrivial case of dynamical noise {εn}n, where εn ∈ N(0, σ2) and the system output is xn = T(xn−1, xn−2, ..., x0)+εn, without any specific knowledge/assumption on T, the quantitative estimation of noise power σ2 is a challenge. Here, we introduce a formal method, based on nonlinear entropy profile, to estimate the dynamical noise power σ2 without knowledge on the specific T function. Time-series generated from Logistic maps and Pomeau-Manneville systems under different conditions are used to test the correctness of the method. Results demonstrate that the proposed estimation algorithm properly discerns different noise levels with no a priori information.

Introduction. Ixodes ticks are vectors for pathogens of many infectious diseases. Recently, during the study of Rhipicephalus geigyi ticks collected from livestock in the Republic of Guinea, a new multicomponent flavi-like RNA virus, called Kindia tick virus (KITV), was discovered with an unusual mechanism for the implementation of genetic information.
The aim of the work is to detect and study the genetic diversity of KITV in ixodes ticks collected in the territory of the Kindia province of the Republic of Guinea.
Material and methods. In 2021, 324 specimens of ticks of the species Amblyomma variegatum, Rh. geigyi, Rh. annulatus, Rh. decoloratus, Rh. senegalensis were collected from cattle. The detection of viral RNA was carried out in individual samples of ticks by RT-PCR, followed by the determination of the nucleotide sequence and phylogenetic analysis.
Results and discussion. KITV detection rates in ticks of the species Rh. geigyi was 12.2%, Rh. annulatus 4.4%, Rh. decoloratus 3.3%. However, the KITV genetic material has not been identified in Am. variegatum ticks, which are one of the dominant species in West Africa. For all virus isolates, a partial nucleotide sequences of each of the four viral segments (GenBank, OK345271OK345306) were determined. The phylogenetic analysis showed a high level of identity (98.599.8%) for each of the four segments of the viral genome with those previously found in the Republic of Guinea. The obtained KITV isolates are most genetically close to Mogiana tick virus, which was previously detected in South America in Rh. microplus ticks and significantly differed from other multicomponent viruses circulating in Europe and Asia, including the Russian Federation.
Conclusion. KITV genetic material was found in three species of ixodid ticks collected from livestock in a number of prefectures of the Republic of Guinea. The infection rate in ticks was 3.312.2%. The continuation of research in this direction remains relevant.

Introduction. SARS-CoV-2, a severe acute respiratory illness virus that emerged in China in late 2019, continues to spread rapidly around the world, accumulating mutations and thus causing serious concern. Five virus variants of concern are currently known: Alpha (lineage B.1.1.7), Beta (lineage B.1.351), Gamma (lineage P.1), Delta (lineage B.1.617.2), and Omicron (lineage B.1.1.529). In this study, we conducted a molecular epidemiological analysis of the most prevalent genovariants in Moscow and the region.
The aim of the study is to estimate the distribution of various variants of SARS-CoV-2 in Moscow city and the Moscow Region.
Materials and methods. 227 SARS-CoV-2 sequences were used for analysis. Isolation of the SARS-CoV-2 virus was performed on Vero E6 cell culture. Sequencing was performed by the Sanger method. Bioinformatic analysis was carried out using software packages: MAFFT, IQ-TREE v1.6.12, jModelTest 2.1.7, Nextstrain, Auspice v2.34.
Results. As a result of phylogenetic analysis, we have identified the main variants of the virus circulating in Russia that have been of concern throughout the existence of the pandemic, namely: variant B.1.1.7, which accounted for 30% (9/30), AY.122, which accounted for 16.7% (5/30), BA.1.1 with 20% (6/30) and B.1.1 with 33.3% (10/30). When examining Moscow samples for the presence of mutations in SARS-CoV-2 structural proteins of different genovariants, a significant percentage of the most common substitutions was recorded: S protein D614G (86.7%), P681H/R (63.3%), E protein T9I (20.0%); M protein I82T (30.0%), D3G (20.0%), Q19E (20.0%) and finally N protein R203K/M (90.0%), G204R/P (73.3 %).
Conclusion. The study of the frequency and impact of mutations, as well as the analysis of the predominant variants of the virus are important for the development and improvement of vaccines for the prevention of COVID-19. Therefore, ongoing molecular epidemiological studies are needed, as these data provide important information about changes in the genome of circulating SARS-CoV-2 variants.

Introduction. A vaccine against hepatitis C has not yet been developed. Recombinant proteins and plasmids encoding hepatitis C virus (HCV) proteins, the components of candidate vaccines, induce a weak immune response and require the use of adjuvants.
The aim of the work was to study the adjuvant action of an aqueous solution of fullerene C60 during immunization of mice with HCV recombinant protein NS5B (rNS5B) that is an RNA-dependent RNA polymerase, or with NS5B-encoding pcNS5B plasmid.
Materials and methods. An aqueous solution of dispersed fullerene (dnC60) was obtained by ultrafiltration. C57BL/6 mice were immunized with rNS5B subcutaneously, pcNS5B intramuscularly mixed with different doses of dnC60 three times, then the humoral and cellular response to HCV was evaluated.
Results. Mice immunization with rNS5B in a mixture with dnC60 at doses of 250 g/mouse significantly induced humoral response: a dose-dependent increase in IgG1 antibody titers was 720 times higher than in the absence of fullerene. There was no increase in the cellular response to rNS5B when administered with dnC60. The humoral response to DNA immunization was weak in mice of all groups receiving pcNS5B. The cellular response was suppressed when the plasmid was injected in a mixture with dnC60.
Conclusions. Dispersed fullerene dnC60 is a promising adjuvant for increasing the immunostimulating activity of weakly immunogenic proteins including surface and other HCV proteins, important for a protective response. Further research is needed to enhance the ability of dnC60 to boost the cellular immune response to the components of the candidate vaccine.
Being There or Non-being There: Memory of Experience in Virtual Space
Authors: Bayrakçı Zeliha
Published: February 2023

When we are present in a space we have been to before, we remember our experiences or events, people, and things related to that space. However, we can remember a space we have not been to and experiences that do not belong to us. We can have memories of them through transferential spaces created by mediums such as images, films, television, or virtual reality. These virtual spaces enable the transfer of experiences and memories. This study focuses on the relationship between experiences in virtual spaces and memory. It problematizes the change in the quality of experiences in physical and virtual spaces and the memories gained from these experiences. Film and virtual reality mediums are chosen to analyze the changes. The study reveals that depending on the types of mediums, characteristic transformations occur in memories obtained from experiences in virtual spaces.
Knowledge and skills. A possible meeting
Authors: Piccinno Marco
Published: February 2023

The essay focuses on the relationship between knowledge and skills, to identify the anchoring points that allow a non-antagonistic and integrated interpretation of these two aspects of learning. The principals on which to build this mediation processes are identified in the distinction proposed by Gardner (2009) between Matter (the set of knowledge related to a scientific domain) and discipline (the processes from which the individual sciences build knowledge around their object of study), as well as in the concept of Abitus (Dewey, 2014; Baldacci, 2006) understood as the set of permanent provisions of subjectivity.

 

Saperi e competenze. Un incontro possibile.

Il saggio focalizza la riflessione sul rapporto tra saperi e competenze, allo scopo di individuare i punti di ancoraggio che consentono una interpretazione non antagonista e integrata di questi due versanti dell’apprendimento. I presidi sui quali costruire i processi di mediazione vengono individuati nella distinzione proposta da Gardner (2009) tra Materia (l’insieme delle conoscenze afferenti a un dominio scientifico) e disciplina (i processi a partire dai quali le singole scienze costruiscono conoscenza intorno al loro oggetto di studio), nonché nel concetto di Abitus (Dewey, 2014; Baldacci, 2006) inteso come l’insieme delle disposizioni permanenti della soggettività.

Published: February 2023

Teaching in principle guides students in teaching and learning activities or implies that teaching is an effort to organize the environment in relation to students and teaching materials that lead to the learning process. Pedagogic competence is the ability of teachers to manage learning, at least covering understanding of educational insights or foundations, student understanding, curriculum/syllabus development, learning design, implementation of educative and dialogical learning, use of learning technology, evaluation of learning processes and outcomes, and development of students to actualize various potentials. This study aims to analyze the improvement of teacher professionalism through motivational style training. This study uses qualitative methods with data collection techniques through observation. The results of this study indicate that the planning stage was carried out well although there were still some shortcomings. LPPM's coordination with the implementation team has been maximized. However, the coordination between the implementation time and partners is still lacking in terms of implementation time which then has implications for the number of participants. Both implementations were quite good, the number of participants had reached the target even though it seemed urgent. In terms of time still not good enough. The third stage of the evaluation is carried out well enough so that it can correct the existing deficiencies.

El despertar de una pasión: la experiencia periodística de Albert Camus en Alger Républicain y Le Soir Républicain
Authors: Becerril-Alvarado Noemi
Published: February 2023

Se realiza una aproximación a la experiencia de Albert Camus en su paso por las publicaciones argelinas Alger Républicain y Le Soir Républicain. Focalizamos nuestra atención en el periodo que abarca de finales de 1938 a principios de 1940 porque consideramos que el análisis de los inicios de Camus en la prensa nos permite advertir el surgimiento y la evolución de una perspectiva, es decir, una manera particular de entender el periodismo que se crea, recrea y refleja en el ejercicio de su carrera en los diarios locales del país africano. Alger Républicain y Le Soir Républicain son testimonios del serio compromiso que, mediante la palabra, asumió el filósofo con las problemáticas de la realidad argelina y europea de su tiempo y de su inquebrantable defensa de la libertad de expresión; es en estas publicaciones que surge y se perfila el desafiante escritor de Combat y el consolidado editorialista de LʼExpress.
¿Por qué falló la publicidad para pacificar Ciudad Juárez entre 2008 y 2012?
Authors: Sigala-Salazar Armando Rene , Flores-Figueroa José De Jesús
Published: February 2023

: Ciudad Juárez, punto estratégico para el trasiego de drogas hacia Estados Unidos, fue calificada como la urbe más violenta entre 2008 y 2012 debido a los homicidios provocados por bandas de narcotraficantes. En plena guerra, el gobierno federal envió al ejército, marina y policía federal para pacificar la región e implantó una campaña publicitaria para que los juarenses se sintieran más apegados a la comunidad y fueran leales a las autoridades. Ambas acciones fueron rechazadas tajantemente por los ciudadanos. Esta investigación estudia piezas publicitarias para determinar los errores de su concepción. Usamos el método de análisis comparativo entre los elementos visuales y la cosmovisión de los habitantes de la ciudad en ese tiempo. Las causas de dicha disfunción fueron: empleo de recursos genéricos, símbolos centralizados, personajes desacreditados, mala selección de medios de comunicación, saturación de mensajes, disociación entre signos y desprecio al sentimiento de segregación de los juarenses.
Medios de sustento económico, social y cultural de mujeres “canasteras” vendedoras de productos agrícolas en un mercado tradicional

Published: February 2023

En la actualidad, cada vez es más visible el rol protagónico de las mujeres rurales en la sociedad. Son evidentes las complejas y diversas estrategias que realizan para ganarse la vida y para ser reconocidas como agentes económicos y sociales de transformación, y como piezas clave del desarrollo rural; sin embargo, aún persiste disparidad en su participación políticosocial. El objetivo del presente trabajo es comprender, desde el enfoque orientado al actor, los medios de vida de las canasteras, creadoras y vendedoras de productos agrícolas en el mercado tradicional Vicente Obregón en la ciudad de Acayucan, Veracruz en México. Se realizó un trabajo etnográfico durante un periodo de seis meses, durante el cual se realizaron entrevistas a profundidad e historias de vida. Las mujeres vendedoras de productos agrícolas en mercados tradicionales son parte del sector económico informal. A partir de ello se identificó que, a pesar de que esta actividad es su principal sustento, las canasteras no pueden acceder a una mejor calidad de vida y que, en su quehacer cotidiano, no sólo intervienen prácticas económicas, sino que éstas se convierten en dinámicas sociales y en reafirmaciones simbólicas. Asimismo, existe una fragmentación en la estructura del papel que juegan las mujeres rurales en la sociedad; las mujeres canasteras están reestructurando su rol de género tradicional asumiendo un papel social y económico más importante. Son agentes del cambio, tienen un rol en el mercado, y representan una parte fundamental en la alimentación de la sociedad.

Published: February 2023

El Programa Jóvenes Construyendo el Futuro surge como una política para combatir el desempleo, subempleo y los bajos salarios en la población joven. El programa pretende capacitar y vincular a los jóvenes con el sector productivo, con la finalidad de que encuentren empleos estables y mejor remunerados. Algunos de los efectos potenciales de esta política pública podrían relacionarse con el crecimiento   económico e impactar en otros aspectos sociales (vivienda, salud, seguridad). Derivado de ello, el presente escrito tiene como objetivo realizar un análisis integral del programa, utilizando el modelo de etapas de Subirats, así como la definición de actores, recursos, reglas y componentes de la política pública y el modelo de Bardach, lo que permitirá efectuar algunas recomendaciones. Los hallazgos muestran que uno de los aspectos a mejorar en la implementación de este programa es el establecimiento de mecanismos de evaluación, por lo que se sugiere una modificación en las reglas de operación del programa, que incluyan los indicadores de evaluación de resultados, la focalización de beneficiarios, la creación de incentivos fiscales para los centros de trabajo participantes y una definición precisa de los planes de capacitación que potencien la vinculación con el sector productivo.
Russia-Ukraine war: independence, identity, and security
Authors: Stępniewski Tomasz
Published: February 2023

The aim of this short paper is to show that the relations between Ukraine and Russia are extremely complex as they are built on a shared history, religion, language, and culture and they should not, therefore, be gauged by Western standards. Evaluating the current situation from a broader perspective, the fact that Ukraine plays a significant role in Russia’s foreign policy needs to be emphasized. Ukraine is considered the key post-Soviet state, a significant “near abroad” country, whose position, potential, and geopolitical location are vital for the balance of power in both Eastern Europe and Europe in general. The research project aims at a synthetic examination of the current Russia-Ukraine war from the point of view of Ukraine striving for full independence, memory, and identity. Will the war of the brotherly nations wreck Russia’s long-term policy towards Ukraine? Will the conflict ruin Russia’s plans of post-Soviet space reintegration, whose pivot is set on Ukraine? Will the war stimulate Ukraine to deal with the issue of its identity, post-Soviet legacy, and collective memory?

Published: February 2023

In terms of the impact of human activity on the natural environment, civil engineering is one of the most significant productive pursuits. The production and use of building materials, the advancement of engineering and construction, the use of the project after it is completed, the removal of discarded components, and other procedures all require significant energy expenditure and ongoing waste generation, which can have severe consequences for the natural environment. To meet the demands of both economic and social development, advancements in civil engineering must be made while also protecting the natural world, limiting the use of natural resources, and promoting sustainable development. This study examines the long-term strategy in civil engineering and explores the role of environmental sustainability throughout the various stages of the civil design process, including the conceptual stage, the technical design stage, and the building stage. The research finds that the construction industry should adopt practices that adhere to sustainability principles such as environmentally-friendly design, durability, energy efficiency, waste reduction, improved indoor air quality, water conservation, and the use of sustainable building materials in construction.
Onset of surface driven convection in selfrewetting fluid layer overlying a porous medium

Published: February 2023

The onset of thermocapillary convective motion in a self-rewetting fluid layer overlying a porous medium with thermally dependent surface tension is studied analytically. Surface tension is assumed to be a quadratic function of temperature. The top surface of a fluid layer is deformably free and the bottom is rigid. We considered boundaries to be insulating to temperature perturbations. The governing equation that satisfies the composite system is analyzed by the normal mode approach and solved by the regular perturbation technique for linear stability. A mathematical expression is derived for the critical Marangoni number by solving coupled equations. The influence of crispation number, thermal diffusivity ratio, and other physical parameters involved therein are analyzed for the convective stability of the bilayer system. It has been found that the start of convection is delayed when the crispation number goes down and the thermal diffusivity ratio goes up. Also, the impact of the ratio of the thickness of the fluid to the thickness of the porous matrix and the other physical parameters on controlling the convective motion of the configuration is examined in detail.

Authors: Mrisho David Haruna , Gwaltu Paul Martin
Published: February 2023

This study assesses the mediating role of future time perspective in the relationship between high-performance work systems and innovative work behaviours of employees in Tanzania’s banking sector. Drawing from AMO theory, social exchange theory, and socio-emotional selectivity theory, we hypothesise that, first, the utilisation of high-performance work systems in an organisation is positively associated with future time perspective; second, the utilisation of high-performance work systems in an organisation is positively associated with the innovative work behaviours of employees in the organisation, and third, future time perspective mediates the relationship between high-performance work systems and innovative work behaviours of employees in a workplace. The findings of this cross-level study constitute 152 respondents from the company level (business unit level) and 220 respondents from the employee level. The results provide empirical evidence that high-performance work systems have a significant and positive effect on future time perspective, high-performance work systems have a positive and significant effect on innovative work behaviour and, importantly, future time perspective has a partial mediation in the relationship between high-performance work system and innovative work behaviour. The practical implications of the study are that managers need to effectively implement HPWS practices to encourage employees to be innovative as mediated by their perception of future prospects. Through this adoption and utilisation of HPWS, organisations can enhance innovative work behaviours amongst employees and therefore organisational performance.

Many research have observable development in the automated vehicle driving field during the last few decades. This research proposed a simple optimum Intelligent PID (SO PID) controller to simplify the automated vehicle motion control. Control of an autonomous vehicle’s steering routines plays an essential key role. Several steering control procedures are proposed that improve automated vehicle performance. The design of secure embedded control systems must overcome the difficulties associated with designing both computing and control systems. Also, this research introduces a model of the autonomous car prototype controlled via an Arduino microcontroller board and the GPS Module to receive the car coordinates. The car moves safely, and autonomously consequently avoiding the risk of human faults. Several algorithms such as angle and distance calculations to the waypoint and obstacle detection are combined to control the car movement.
