Fibrous wastes correspond to approximately 54.3 wt.-% of a banana plant. The waste weight is mainly of bunches, stems, and leaves. These ligno-cellulosic fibre waste can be designed and tailored to yield value added products which can be exploited by the farmers, exporters and weavers. Pectin (plant cement) and hemicelluloses (22-25%) found in plant cell walls in the plate (middle lamella). These macromolecules have needs to be hydrolyzed faster without affecting the quality of fibre. The chemical and mechanical processes adopted for fibres actually affect color uptake, strength of fibre thus fetching lower price. We report a biological ecofriendly method of retting where pectinases produced by the endophytic microorganisms of banana pseudostem were used to separate the fibre bundles of cellulose.. Endophytes are microorganisms which live in close relationship with living plant tissues in a cooperative relationship delivering a few auxiliary metabolites and proteins with the possibility to hydrolyse a few plant-determined macromolecules of the host. They spend the entire or part of their lifecycle colonizing within sound tissues of the host plants.The endophytic pectinase helps to break down the cell walls and can find commercial application in extraction of fibres.Seven bacterial isolates were screened and isolated in pectinase screening agar medium [PSAM]. Pectinase producing endophytic bacteria is isolated from corm of Amorphophallus paeoniifolius reported by us are Staphylococcus sciuri, Exiguobacterium acetylicum, Exiguobacterium indicum which are good pectinase producers having specific activity of 8.26, 12.61, 6.81 respectively. Treatment of banana pseudostem with these microbes showed 91%, 94%, 96.7% loss in the total weight of stem leaving behind pure cellulose fibres.

DC–AC inverters play a crucial factor in the modern era to satisfying the demand of energy conversion, which is definitely for a better lifestyle and developing smart facilities. In this paper a deeper study has been taken place to understand the behavior of the inverter base on three phase bridge inverters. The scenarios for the inverters respectively with pure resistive loads R and inductive resistive loads RL are both discussed. The term load is referring to the brushless DC motor (BLDC) which is more reliable than regular or permanent magnet DC motors, this study will help to understand the effect of these components in the inverters. These effects could be related to friction and other electrical problem such as spark which they are associated with the DC components’ operation. Moreover, solving differential equations numerically using powerful software such as MTLAB, which certainly solidify the comprehension of the system operation. The inverter was simulated using MATLAB as a variable DC and AC power supply to in investigate the effect of varying the parameters of the reference input signals such as carrier frequency, duty cycle and the output load such as inductance. Finally, a flowchart of the system is included described both hardware and software.
ANALYSIS OF THE STORIES OF U. HAMDAM IN THE CONTEXT OF MODERN UZBEK LITERATURE OF NEOREALISM
Authors: AKHMEDOVA Madinabonu
Published: October 2021

The article is devoted to the problem of the evolution of the modern hero and types of heroes in the modern Uzbek literature of neo-realism. The poetics of neo-realism marked by a combination of descriptive concreteness and object precision with expressive and lyrical often-symbolized words; characterized by a weakening of narrative connections by strengthening the lyrical beginning and in-depth psychologism. Neo-realism in Uzbek literature, while possessing national features, in terms of poetic and stylistic orientation, is fundamentally different from neo-realism in Russian and Western literature. The works of A. Yuldashev and U. Khamdam are the bearers of this line in Uzbek prose. Along with the synthetic nature of the texts of these writers, there is a feature that unites them all — the desire of prose writers not to paradox, but to reality. The purpose of this article is to consider the philosophical perception reflecting the state of mind of modern man through the prism of the perception of the literary hero in the Uzbek literature of the XXI century. Ulugbek Hamdam in the stories «Камень», «Река души моей» (“The Stone", “The River of My Soul”) with the help of conventionality and signs-symbols, as well as building the work on the basis of functional relationships, builds his author’s concept on the material of everyday life. Abdukayum Yuldashev in the stories «Пуанкаре», «Близнецы» (“Poincare”, “Twins”) having a rich style arsenal, also works at the interface of realism and neo-realism. The article attempts to analyze the main features in the typology of the hero in the stories of U. Hamdam in the context of the traditions of new realism.

En el transcurso de los años se extendió hacia Europa, Asia y América Latina, donde ha sido y es utilizado por diversas escuelas y facultades en centros de investigación y universidades de prestigio. Se trata de una metodología de aprendizaje activo, en donde el alumno se enfrenta a un problema real y específico y comprende, conoce y analiza el contexto en el que se presenta.Al utilizar esta metodología se ve beneficiado tanto el catedrático como el alumno, ya que el primero aprende a analizar hacia dónde quiere llegar y lo que pretende demostrar, además de que motiva al alumno a tener un juicio crítico. Por su parte, el alumno desarrolla un liderazgo participativo, un pensamiento crítico, una actitud de cooperación, de intercambiar ideas y de adquirir nuevos conocimientos.
Peppa Pig ¿una caricatura educativa?
Authors: Romero Martínez Larisa Anahí
Published: October 2021

En este artículo se presenta un análisis de la caricatura Peppa Pig, producida por Channel 5. El objetivo del análisis fue identificar si en sus estructuras narrativas había elementos educativos, psicológicos y emocionales; para ello se examinaron cuatro capítulos de la segunda temporada, llevando a concluir principalmente que el programa infantil tiene mensajes educativos, lo que genera conductas prosociales en los niños, pero que es importante que los padres supervisen a los niños, ya que en el programa hay algunos comportamientos inadecuados de Peppa, principalmente con Papá Pig, los cuales los niños podrían imitar con facilidad. Sin embargo, dentro de la sociedad hay normas culturales, reglas y formas de expresarse, que ésta acepta o rechaza. Precisamente por esto es fundamental que los padres estén al pendiente de lo que sus hijos ven en un programa, aunque sea una caricatura.
Modeling, Estimation, and Optimal Control of Anti-COVID-19 Multi-dose Vaccine Administration
Authors: Scarabaggio Paolo , Carli Raffaele , Cavone Graziana , Epicoco Nicola , Dotoli Mariagrazia
Published: October 2021

The recent trends of the COVID-19 research are being devoted to disease transmission modeling in presence of vaccinated individuals, while the emerging needs are being focused on developing effective strategies for the optimal distribution of vaccine between population.

In this context, we propose a novel non-linear time-varying model that effectively supports policy-makers in predicting and analyzing the dynamics of COVID-19 when partially and fully immune individuals are included in the population. Specifically, this paper proposes an accurate SIRUCQHE epidemiological model, with eight compartments (namely, Susceptible, Infected, Removed, Unsusceptible, Contagious, Quarantined, Hospitalized, and Extinct).

Differently from the related literature, where the common strategies typically rely on the prioritization of the different classes of individuals, we propose a novel Model Predictive Control approach to optimally control the multi-dose vaccine administration in the case the available number of doses is not sufficient to cover the whole population. Focusing on the minimization of the expected number of deaths, the approach discriminates between the number of first and second doses, thus considering also the possibility that some individuals may receive only one injection if the resulting expected fatalities are low.

To show the effectiveness of the resulting strategies, we first calibrate the model on the Israeli scenario using real data to get reliable predictions on the pandemic dynamics. Lastly, we estimate the impact of the vaccine administration on the virus dynamics and, in particular, based on validated model, we assess the impact of the first dose of the Pfitzer's vaccine confirming the results of clinical tests.

Why do Sovereign Borrowers Post Collateral? Evidence from the 19th Century

This paper explores the reasons why sovereign borrowers post collateral. Such behavior is paradoxical because conventional interpretations of collateral stress repossession of the assets pledged as the key to securing lenders against information asymmetries and moral hazard. However, repossession is generally difficult in the case of sovereign debt and in some cases impossible. Nevertheless, such sovereign “hypothecations” have a long history and are again becoming very popular today in developing countries. To explain sovereign collateralization, we emphasize an informational channel. Posting collateral produces information on opaque borrowers by displaying borrowers’ behavior and resources. We support this interpretation by examining the hypothecation “mania” of 1849-1875, when sovereigns borrowing in the London Stock Exchange pledged all kinds of intangible revenues. Yet, at that time, sovereign immunity fully protected both sovereigns and their assets and possessions. Still, we show that hypothecations significantly decreased the cost of sovereign debt. To explain how, we stress the pledges’ role in documenting sovereigns’ wealth and the management of revenue streams. Based on an exhaustive library of bond prospectuses collected from primary sources, matched with a panel of sovereign bond yields and an innovative measure of sovereign fiscal transparency, we show that collateral minutely described in debt covenants served to document and monitor sovereign resources and development prospects. Encasing this information in contracts written by lawyers served to certify the quality of the resulting data disclosure process, explaining investors’ readiness to pay a premium.
BCH CODES DECODER BASED ON EUCLID ALGORITHM
Authors:   Novosibirsk State Technical University, Filippov B.I.
Published: October 2021

In the process of algebraic decoding of BCH codes over the field GF(q) with the word length n = qm-1, correcting t errors, both in the time and frequency domains, it is necessary to find the error locator polynomial ?(x) as the least polynomial for which the key equation. Berlekamp proposed a simple iterative scheme, which was called the Berlekamp-Messi algorithm, and is currently used in most practical applications. Comparative statistical tests of the proposed decoder and decoder using the Berlikamp-Messi algorithm showed that they differ slightly in decoding speed. The proposed algorithm is implemented in the environment in Turbo Pascal and can be used for the entire family of BCH codes by replacing the primitive Galois polynomial.

In this time and age, technology is on an ever-developing trend, bringing with it a plethora of new advancements to daily life and common activities, but with these advancements, a whole new set of issues and vulnerabilities become present. This paper aims to discuss and propose a solution to the vulnerability of physical security lockers, a facet of security that many organisations tend to neglect. It aims to provide an elevated level of security for companies who use physical lockers to secure sensitive information or important contents. More specifically, the paper discusses the plausibility and the advantage of utilising multi-factor authentication with dynamic passwords or OTP code for short and facial recognition to access physical lockers. The proposed system will require employees to have accounts in their respective locker by entering their respective ID and passing the facial recognition feature. The system will then provide the employee with an OTP code, allowing the company an extra layer of security from intruders or malicious individuals.

The Communitas of Mourning: Women in Black and Dah Teatar between War protest and Theater
Authors: Biberstein Sandra
Published: October 2021

In wartime and post-war situations, the opposition of friend and enemy—based on national divisions—often condemns the dead “enemies” to be ungrievable. To grieve for the excluded others in such times means to break with the friend-enemy opposition. This article examines how the friend-enemy opposition is broken in the case of the actions of Women in Black and Dah Teatar in the context of the civil war in Yugoslavia. By analyzing the vigils of Žene u crnom (Women in Black) in Belgrade and the play Priča o čaju (The Story of Tea) by Dah Teatar, the author discusses the particular strategies through which grief was made possible beyond the friend-enemy opposition and how these strategies open a communitas of mourning. The term “communitas of mourning” refers to the concept of grievability, proposed by Judith Butler in Frames of War.
DIFFRACTION EXPERIMENTS WITH KOSSEL PHOTONS
Authors:   St Petersburg State Institute of Technology (Technical University), Nikotin Oleg P.
Published: October 2021

In the paper an attempt was made to obtain some information about the characteristics of photons as separate objects with the properties of localization in ordinary coordinate space. Experiments of various complexity with Kossel photons were carried out on a multiaxial diffractometer. A diffraction spectrometer with perfect calcite crystals was used to register the photons. The bidirectional angular measurements were carried out with sufficient angular and energy resolution to detect the influence of the coherent volume of the photons on the measurement results. The measurements showed some correlations that had not been paid enough attention before. Those effects were measured separately for Kα1 and Kα2 photons to allow their comparison. Such approach corresponds to the modern quantum mechanics of the photon; that mechanics showed the possibility of existence of wave functions of photons in their usual standard sense. Data on spatial parameters Kα1 and Kα2 of Kossel photons were obtained by comparing the effects of their diffraction scattering
Family caregivers’ support for older adults in Nigeria
Authors: Jika Barbara Member
Published: October 2021

A scoping review of literature was explored for a better understanding of the lived experiences of family caregivers for elderly in Nigeria. Unlike professional caregivers such as medical doctors, nurses and trained care workers, informal caregivers, often family members, or friends, also provide care to individuals with a variety of conditions including cancer, dementia, and advanced age. Family Caregivers of elderly with chronic illness in Nigeria, are exposed to burden associated with caregiving activities. This could involve the delivery of complex health care services alongside Activities of Daily Living (ADL).

The globalizing world, the rapid increase in industrialization and urbanization rates have increased the world’s need for energy day by day, making energy one of the most important agenda items of the world. Increasing demand has led the countries to ensure supply-demand balance to become one of the basic energy policies. One of these prominent energy policies is to ensure diversity in supply and to turn towards renewable resources that are not dependent on exhausted fossil fuels. One of these renewable sources is photovoltaic (solar cell) energy generation systems that generate electrical energy from solar energy. Solar energy is a good alternative to fossil fuels as it has an environmentally clean source feature. In this study, the performance evaluations of power plants were made by comparing the simulation results with data obtained from established fields in three different geographical regions of Turkey. In addition, regional production efficiency was analyzed by comparing the production values of the plants among themselves. An interface program that analyses instant power plant values was designed and a practical evaluation software was created.

Micro-drilling of AISI316L is very challenging task. Unconventional machining process may be used for such type of operation. Laser beam drilling is a best for micro drilling. High thermal energy and converging-diverging property of laser beam affects the quality of laser drilled holes. In present work Nd:YAG laser beam has been used and investigate effects of laser input parameters on responses. To minimize number of experiments, get extreme information for experimental trials. Central composite rotatable design approach has been adopted. Analysis of variance is used to find reliable input parameters, are affecting responses. From this paper, it is found that current and gas pressure are significant for hole circularity at top. Current and pulse frequency are significant for bottom side circularity. Current and cutting speed are significant parameter for hole taper.

The transportation of the solid material using hydraulic transportation method is economically the best method. The head loss occurs during transportation of slurry through horizontal pipelines usually depends on the rheological behavior of slurry, slurry concentration, particle size, and influx velocity. An experimental investigation has been performed using sand-water slurry flowing through the horizontal pipe section of a pilot plant test loop. The head loss obtained from the experimental results was validated through CFD simulation using FLUENT. The solid concentration of sand-water slurry and influx velocity used during both experiments and numerical simulation were in the range of 10-40% (by weight) and 1 to 4 m/s respectively. The numerical simulations were performed using five different turbulence models and the results obtained using SST k-omega model was in close agreement with experimental results. It is observed from both the experiment and numerical analysis that the pressure loss, granular pressure, volume fraction and skin fraction coefficient during transportation of slurry through a horizontal pipe is a function of solid concentration and influx velocity. The present study observed that as the flow velocity increases four times, the pressure loss is increasing more than 10 times. Uniform volume fraction at middle zone of outlet of the pipe is observed as both the slurry concentration and velocity of flow increases.

More and more dynamic reactive power devices (DRPDs) have been put into operation to improve voltage stability in AC/DC hybrid power system. In order to make full use of these devices, this paper presented an optimization technology for multiple DRPDs’ coordinate operation in receiving-end of AC/DC hybrid power system. DRPDs’ steady-state reactive instructions are treated as optimization variables in the proposed model, while the objective is minimizing the successive times of HVDC’s commutation failure under a number of grounding faults. Power flow constraints and electro-mechanical transient process are considered simultaneously. Based on the characteristics of the model, commutation failure of HVDC under each grounding fault could be obtained by employing time-domain simulation method. Furthermore, particle swarm optimization (PSO) is used to get DRPDs’ optimal reactive instruction in steady-state. The simulation is done by considering Jiangsu power grid in eastern china, including synchronous condenser, STATCOM and UPFC. The results show that the proposed model and algorithm are corrective and effective.

Introduction. The aim of the work was development of enzyme immunoassay for detecting I and II types of shiga-like toxins and assessment of it diagnostic properties. Materials and methods. For the research, we used hybridomas producing monoclonal antibodies to shiga-like toxins of types I and II, obtained at the branch of the Federal State Budgetary Institution “48 Central Research Institute” of the Ministry of Defense of Russian Federation (Kirov); BALB/c mice; shiga-like toxins of types I and II. Hybridoma cells were cultured in culture flasks and in the peritoneal cavity of BALB/c mice. Monoclonal antibodies were isolated from ascitic fluids by precipitation with a saturated solution of ammonium sulfate, followed by purification by ion exchange chromatography. The obtained preparations of monoclonal antibodies were used to develop enzyme immunoassay for the detection of shiga-like toxins of types I and II. Specific components of enzyme immunoassay were freeze-dried in a protective environment. Results. As a result of research, preparative quantities of monoclonal antibodies against I and II types of shiga-like toxins were obtained and purified; selection of monoclonal antibodies for sorption on the solid phase and for the synthesis of immunoperoxidase conjugates was carried out. Conclusion. experimental enzyme immunoassay allowing to identify 1 ng/ml I and II types of shiga-like toxins in «sandwich»-ELISA was developed.
Compulsory Heterosexuality and Homophobia: Reading of Under the Udala Trees by Chinelo Okparanta and The World Unseen by Shamim Sarif
Authors: Chepkoech Judith , Wesonga Robert , Anudo Cellyne
Published: October 2021

Traditionally, sexuality has often been determined by one’s gender and has further been complicated by heterosexism and homophobic ideas. This paper examines the topic of sexuality as portrayed in fiction from selected literary texts. It constitutes the discussion of various factors that affect people at different levels in association with same-sex relationships, as reflected in the literary texts. The main objective of the paper is to analyse how heteronormative societies respond to lesbian homosexuality. To establish this argument, this paper explores Sarif’s The World Unseen (2007) and Okparanta’s Under the Udala Trees (2015). It seeks to answer the question: what is (are) the response(s) of heteronormative society to lesbianism in the selected texts. Ultimately it hopes to contribute to the existing but limited research on understanding experiences of lesbian homosexuals by shedding light on cultural practices that are put in place in an attempt to normalise heterosexuality. The paper utilises Judith Butler’s Queer theory to achieve its objective. The significant concern in this theory is the correlation between gender and sex. The major tenets being gender performativity, the fluid nature of sexuality, and the deconstruction of characterisation structures.

Gender differences impact the work that professionals engage in with sexual offenders and victims of sexual trauma (with females often perceived as more likely to experience sexual trauma, and males as more likely to commit a sexual offence). However, there is no evidence looking at these factors in combination. This study aimed to address this gap, asking: “Are experiences of nursing staff working with sex offenders with a history of sexual trauma affected by gender differences, that is, in terms of gender of the staff member, and gender of the client they are working with?” Eight participants, (four male, four female) working within a Forensic Mental Health Service took part in semi-structured interviews. Interviews were transcribed and analysed using Interpretative Phenomenological Analysis. Five superordinate themes emerged from the data, along with a number of subordinate themes. Superordinate themes included: ‘Gender has a role’, ‘The trauma response’, ‘How we cope’, and ‘What we need’. Nursing staff working with sexual offenders with historic sexual trauma found work to be challenging both emotionally and socially. Such challenges were complicated by the gender interaction between them as professionals, and the patients who have experience of being both victims and perpetrators of sexual abuse.
