Authors: Ahmad Sohail , Basharat Ponam , Abdullah Saleem , Botmart Thongchai , Jirawattanapanit Anuwat
Published: August 2022

The Covid-19 emergency condition is a critical issue for emergency decision support systems. Controlling the spread of Covid-19 in emergency circumstances throughout the global is a difficult task, hence the purpose of this research is to develop a non-linear diophantine fuzzy decision making mechanism for preventing and identifying Covid-19. Fundamentally, the article is divided into three sections in order to establish suitable and correct procedures to meet the circumstances of emergency decision-making. Firstly, we present a non-linear diophantine fuzzy set (non-LDFS), which is the generalisation of Pythagorean fuzzy set, q-rung orthopair fuzzy set, and linear diophantine fuzzy set, and explain their critical features. In addition, algebraic norms for non-LDFSs are constructed based on particular operational rules. In the second section, we use non-LDF averaging and geometric operator to aggregate expert judgements. The last section of this study consists of ranking in which MABAC (multi-attributive border approximation area comparison) method is used to handle the Covid-19 emergency circumstance using non-LDF information. Moreover, based on the presented methods, the numerical case-study of Covid-19 condition is presented as an application for emergency decision-making. The results shows the efficiency of our proposed techniques and give precise emergency strategies to resolve the worldwide ambiguity of Covid-19.

Authors: Sharma Anand , Bhatt Alekha Parimal
Published: August 2022

IoT-based healthcare is especially susceptible as many IoT devices are developed without keeping in mind the security issue. In addition, such smart devices may be connected to global networks to access anytime, anywhere. There are some security challenges like mobility, computational limitation, scalability, communication media, dynamic topology, and above all the data confidentiality in storage or in transmission. There are some security protocols and methodology which is used in IoT-based healthcare systems like steganography, AES cryptosystems, and RSA cryptographic techniques. Therefore, it is necessary to use quantum cryptography system to make sure the security, privacy, and integrity of the patient's data received and transmitted from IoT-based healthcare systems. Quantum cryptography is a very fascinating domain in cyber security that utilizes quantum mechanics to extend a cryptosystem that is supposed to be the unbreakable secure system.
Implementation of a Reversible Watermarking Technique for Medical Images
Authors: Karmakar Ranit , Basu Abhishek
Published: August 2022

Electronic health records (EHR) contain patients' medical as well as personal details. With the increased use of digital media, these data are stored and transferred through the electronic media all over the world. This makes it vulnerable to unauthorized people. Digital image watermarking can be a useful process of protecting these data from attacker but causes severe and unrecoverable damage to cover media. In the case of highly sensitive images like medical images, this might creates a problem during further diagnosis. In this chapter, a reversible data hiding algorithm is proposed which also is capable of holding a large chunk of data without affecting the cover media. The main cover image is first reconstructed and hidden behind a bigger media and then the extra pixels are used to hide encrypted forms of EHR data along with an authentication signature. As EHR data and the digital signature is passed through various encryption stages while encoding, it is made more secure. The algorithm is developed on the spatial domain adding some cautious measures which made it fragile as well.
Role of a Nineteenth Century Woman's Divinity in Self-Formation
Authors: Sinha Anutosh
Published: August 2022

Rashsundari Devi's autobiography, the first of its kind by any Bengali woman, Amar Jiban is the testimony of a 19th century Bengali woman's ordeals. It not only highlights the theme of women's education through her yearning for knowledge of letters; it also calls for equal spiritual status for women as she personally yearns for God. She chooses to rewrite her life in this autobiography, broadly in alignment with God's life. She attributes to God every good or bad thing happening around, even her life with transgressions. The chapter showcases how the re-presented self of Rashsundari follows the broad religious codes, yet not in the customary way and her personalized fantastic experiences, like precognitive dreams, help her mould the shape of her God. The author invokes the guru-shishya dynamics and looks through the glass of a few religious texts of Hinduism, especially the Bhagavad Gita, to analyse whether she transgresses from the whole religious system or actually encodes her discontent uniquely on the bedrock of religious following, adherence, and devotion.
Breaking the Silence
Authors: Rawat Gargee , Semwal Sakshi
Published: August 2022

Gender equality has been a can of worms. From the waves of feminism till LGBTQ, some people, due to their otherness, have endured bigotry and social stigma. We've been fed with heteronormativity for a long time and there exists a void when it comes to homosexual tolerance. Although a lot has been written about them, transgender people still have not been legally recognized worldwide. Their demand for identity and getting rid of the derogatory terms they were labelled with like hijras, chakka, kinnars, jogappa, aravani, aruvani, etc. is visible everywhere. Recently, LGBTQ is considered taboo in society because of some stereotypical mindsets. This chapter focuses on the lives of transgender people in and around Pakistan majorly by dwelling deep into the kind of behavioural patterns society shows toward them by taking the text of Alternative Realities (Nighat M. Gandhi, 2013) as a representation of the LGBTQ community's voice.
Unlearning Internalized Homophobia With My Brother's Husband
Authors: Debnath Anushkaa
Published: August 2022

The manga My Brother's Husband (2014-2017) talks about a little Japanese neighborhood, the microcosm representing the country's general approach to homosexuality and how the future holds a promise to change for better days. Homosexual relationships and trans identities are frowned upon in the general society of modern-day Japan, just like in many other Asian countries. An openly gay mangaka, Gengoroh Tagame, had so far been a name limited to the gay erotic manga circuit, but this work, targeted at a more general audience, won him critical acclaim for depicting the struggles of being queer in Japan. This chapter is an attempt to understand how Yaichi is a representative of the cis-heterosexual male who is trying his best to navigate out of the patriarchal maze of heteronormativity that has been propagated through generations following European imperialism in Asian countries.
Portrayal of Helen of Troy in the Select Poems of Sappho and Wislawa Szymborska
Authors: Dasgupta Rushati
Published: August 2022

The Greek society was highly patriarchal; it was a masculine world where war was glorified. Helen of Troy is one of the most imperative characters in both ancient and modern literature. For centuries she has been portrayed as the woman whose beauty sparked the Trojan War. But there are writers whose characterization of Helen and description of her beauty differ from the stereotypical mainstream narrative. This chapter investigates how the mythical character of Helen has been explored by such female writers, through poems of Sappho and Wislawa Szymborska. In Sappho's “Fragment 16,” the readers observe how she refashions the character of Helen and projects her as a “hero” because she had followed her heart. She only mentions her beauty and does not describe her in an elevated way. But Szymborska is more effective in describing the consequences of her unsurpassed beauty that becomes her weapon. In the poem “A Moment in Troy,” Szymborska criticizes the internalization of patriarchal values. She manipulates patriarchy by using a patriarchal narrative to empower women.
There Was No Escape Epiphany
Authors: Lobo Malvika Manisha
Published: August 2022

Clarice Lispector is one of the most prominent figures of literary modernism in Latin America. Her oeuvre explores themes of existentialism, narratives of silence, and various ideas of freedom. Her self-reflexive style of writing and experimentation with the Portuguese language reflects her attempt to invoke alternate meanings through her narrative. The characters' identities in her short stories through their exploratory nature give rise to a great deal of identity and gender play. They provoke possibilities and prospects to create new gender roles and subversive practices by the manifestations of thoughts and actions in various ways. This chapter examines her use of the epiphany in her short story “Love” from the collection of short stories entitled Family Ties. The focus rests on the symbolic violence that ensues from this deviation through thought (language) and action as a response to subversion under patriarchy. The theoretical approach reads against the grain in the light of Viktor Shlovsky's “defamiliarization” and Pierre Bourdieu's notion of habitus and field.
An Ecofeminist Reading of Amitav Ghosh's Jungle Nama
Authors: Sengupta Sayantani
Published: August 2022

The relationship between women and nature is powerful. Through various legends and folktales, women have been projected as the goddesses who would save the forests as well as save the world from overconsumption and greed. The focus of this chapter is one of the popular legends of India, the legend of Bonbibi in Amitav Ghosh's Jungle Nama. Bonbibi is widely worshipped by the people of the Sundarbans, which has been mentioned by Ghosh in his novel The Hungry Tide. But the primary focus of Jungle Nama is on the three central characters, Dukhey, Dhona, and Dokkhin Rai, and how Bonbibi comes as a saviour of the young boy, Dukhey, and thus becomes the preserver of the natural order. On the other hand, Manasa, the snake goddess can also be portrayed as someone who maintains a balance between life and death, avarice and generosity, as well as good and evil. The chapter intends to critically study Ghosh's retelling of the Bonbibi legend through an ecofeminist lens and also includes the story of Manasa to substantiate the interconnections between women and nature.
The Women in the Fictions of Arundhati Roy
Authors: Sengupta Jagriti
Published: August 2022

Arundhati Roy, the world-renowned novelist and political essayist from India, is a dominant voice against injustice perpetrated against the marginalized in the country. For her, the marginalization of women is part of a process through which social oppression is unleashed upon the weak. Roy got the prestigious Booker prize for her debut novel, The God of Small Things. The fiction brought out the unjust politics of caste and gender discrimination inherent in an orthodox society. However, after her first fiction, Roy shifted gear to non-fictions that she continued to write for almost two decades. Roy got engaged in more serious political debates and became a powerful critic of corporate globalization. In 2017, Roy published her second novel, The Ministry of Utmost Happiness. In it, Roy offered a journalistic review of all the sociopolitical events of the post-Independent India. This chapter examines that the women protagonists in Roy's fictions extend solidarity to others who are in the margins because, according to Roy, feminism should be a powerful force against oppression in general.
“It's My Story”
Authors: Ashok Anusha
Published: August 2022

The imposing corpus of Indian mythology has long stood uncontested and unquestioned as a repository of narratives that demarcate the heroes and the villains with the collective sympathy leaning towards the former. The depiction of the antagonists in epics like the Ramayana and the Mahabharata were carefully constructed to cement their positions as figures that would incite hatred and disgust and as foils to their infallible hero counterparts. The purpose of this chapter is to reconsider the character of Shoorpanakha as a victim of circumstance and masculine domination as opposed to the malevolent individual that she is portrayed in the epics, through the lens of subalternity and feminism, as represented in Sengupta's play Thus Spake Shoorpanakha, So Said Shakuni. The conscious decision of giving a voice to those who were vilified and shunned is an instance of revisioning. It defies conventional knowledge of the two crucial metanarratives and the dominating discursive practices. It does not lend itself to the restricting binary of good and evil and allows agency to own their narrative.

Published: August 2022

In this 21st century, the world, as well as societal norms, changes rapidly due to globalization. The feminist movement is one of the important outcomes of these societal changes. Nowadays the status or position of women becomes progressed as we find them in every pace of the world due to the waves of the feminist movement. This chapter examines how women got their rights to introduce themselves in this patriarchal society, the history of the world of women's literature – how women introduce themselves as writers and the way they are depicted within the world of literature, and the present scenario of women in the society as portrayed in the world of literature through selected literary texts as contexts.
Women in Partition Literature
Authors: Bhattacharya Trisha
Published: August 2022

This chapter is a comparative analysis between partition literature from Bengal and Punjab showing how even though there is a minor divergence in literature from these two sides owing to the political realities, for the most part literature from these two sides shows overwhelming convergence. In order to draw a comparative analysis, the author uses eight pieces of partition literature—four each from Bengal and Punjab. The chapter is divided into three sections: The first section discusses the relevance of Partition literature for studying Partition and how partition was experienced different by Punjab and Bengal in the political sense. The second section presents the analysis of the one most significant divergence between literature from the two sides, and the final section presents a discussion of the overwhelming convergence between women's experience of Partition on both sides and how it is not a surprising fact.
A Feminist Reading of Panthoipi Khongkul
Authors: Yumnam Rosy
Published: August 2022

The voices of women are often marginalised and silenced. In modern feminism, Kate Millett's Sexual Politics (1970) used the term “patriarchy” (rule of the father) to describe the cause of women's oppression. Panthoipi Khongkul is a myth narrative of Manipur, a state in Northeast India, detailing the rebellion of a legendary woman, Panthoipi, against the patriarchal society of the early Manipuri. The text details how Panthoipi bravely defied the social customs and chose to be united forever in bliss with her paramour. The myth narrative deals with the desire of a woman represented by Panthoipi to ascertain her dignity and identity in a patriarchal society. This chapter seeks to examine the feminist perspective of how “woman” has been represented in Panthoipi Khongkul in the context of the early patriarchal Manipuri society. It further explores on how the feminist reading of Panthoipi Khongkul will assist in striving to achieve equality of sexes.
The Role of Haptics in the Sexual Harassment of Women in Corporate Sector
Authors: Dhal Shraddha
Published: August 2022

The quintessence of a woman's modesty is her sex. The one, intending to outrage a woman's modesty, be it in her personal life or at her workplace, shall be punished. Fortunately enough, women have a powerful sense of differentiating between the touch that gives solace and the touch that is misleading and is used for sexual stimulation. Haptics plays a vital role in this regard. As the world is being globalized, it is onerous to avoid the chance of crossing the line of acceptability. Even so, it is quite important to learn the proper use of haptics to remain aware of the inappropriate act of touching as well as to avoid awkward and embarrassing occurrences. The chapter attempts to emphasize how the proper use of haptics in the corporate sector can add more productivity to both men and women while at the same time it can also enhance the efficiency of the organization.
“Knowledge Is Power, Power Is Also Knowledge”
Authors: Sarkar Dolon
Published: August 2022

The chapter explores the complex intersection of gender, knowledge, and power as manifested in Rokeya Sakhwat Hossain's feminist text Sultana's Dream. In this story, she imagines a world of women beyond the patriarchy. She reverses the stereotypical process of gender roles and reclaims women's space in socio-cultural and political domination. There is an idea that subverting the performative role of gender will lead women to autonomy and power. For her, scientific education and sustainable use of nature are the abundant sources of alternative power. The tactical use of women's scientific knowledge displeases and controls the superior authoritative forces of patriarchy. This decisive role of science is an alternative mode of organizing society and the exceptional development of the particular category of alternative apparatus. The chapter delineates Kate Millett's notion of the reversal of gender roles by mediating Michel Foucault's concepts of power and knowledge.
Photocatalytic Degradation of Rhodamine B Dye by Nanocomposites: A Review
Authors: Kiran Kiran Kenchappa , Ramesh D. , Shashanka Rajendrachari
Published: August 2022

Pollution by textile dyes on waterbodies is an issue for both human health and the environment. To remove/degrade dyes, many approaches (coagulation, membrane separation, and adsorption) have been investigated. However, the use of semiconductor-assisted materials in conjunction with sustainable solar energy has emerged as a possible solution to the problem. Although single component photocatalysts have been tested, composites of semiconductor materials are being employed owing to their low efficiency and stability due to the high recombination rate electron-hole pair and inefficient visible light absorption. By combining two or more semiconductor components, semiconductor heterojunction systems are created. Overall stability is increased by the synergistic impact of their features, such as adsorption and better charge carrier movement. This paper discusses current advances in advanced nanocomposite materials utilized as photocatalysts, as well as the utilization of heterojunctions, crystallinity, and doping to improve photocatalytic characteristics. The conclusion includes a summary, research gaps, and a forecast for the future. This study will aid in the development of efficient heterostructure photodegradation systems by providing a comprehensive appraisal of recent advances in demonstrating effective nanocomposites for photodegradation of Rhodamine B dye under ideal circumstances.

Authors: Augustia Venitalitya A.S. , Kamariah Kamariah , Mulia Fitri , Nurani Dewanti Siwi
Published: August 2022

Along with the increase in watermelon production, the amount of watermelon rind waste increased. The total mass of fruit rind in a watermelon reaches around 30 percent and this fruit rind can increase the quantity of organic waste in Indonesia. The outer portion of the watermelon rind has a green layer containing a large amount of anthocyanin and a white layer containing flavonoids. In this study, the extract of watermelon rind containing anthocyanins and flavonoids was protected from damaging conditions using the ionic gelation encapsulation method. Chitosan (CN) was used as a natural polymer in this encapsulation method and sodium tripolyphosphate (TPP) was used as an ionic crosslinking agent. The total of flavonols content (TF), microstructure test, in vitro releasing test, and shelf life of microcapsules were observed in the various ratio between watermelon rind and the solvent. From the process, can be concluded that higher watermelon skin levels will produce the most flavonoid microcapsules (70g/35 mL). At 70g/35 mL or 2:1 g/mL watermelon skin levels give the best flavonoid release test results, especially if it will be applied to the pharmaceutical industry, which follows a controlled release method.

There is a lack of information on the magnetic properties of particles of such materials as powder magnetic (modified by inclusions of magnetite and maghemite) carbon sorbents intended for water purification from various kinds of impurities and, what is especially important, allowing to perform the prompt isolation of the spent sorbent – by magnetic separation. The data on the magnetic susceptibility χ of the particles of these sorbents, found by the developed experimental calculation method based on the concept of the corresponding magnetometry of a moderately rarefied dispersed sample with a dispersed phase of the particles under study, are presented. Experimental dependences of the magnetic susceptibility of <χ>of a dispersed sample on the volume fraction γ of controlled particles in it have been obtained - for different values ​​of the magnetic field strength H in the range from 22 to 61 kA/m, i.e. in the postextremal region for the susceptibility. In addition to the necessary assessment of their linear, located at γ ≤ 0.15-0.2, sections, this also made it possible to find and phenomenologically describe the field dependences of the generalized data of the reduced susceptibility of <χ>/γ, i.e. data χ: in the form of an inverse power function with a power of 0.7 ... 0.8 at H.
Uncovering the Brazilian Orthocentrinae (Hymenoptera: Ichneumonidae) fauna: high diversity at high elevation
Authors: Camargo Luiza Figueiredo , Shimbori Eduardo Mitio , Penteado-Dias Angélica Maria
Published: August 2022

The Orthocentrinae is one of the least-studied groups within Ichneumonidae and possibly a major component of the tropical fauna, encompassing a rich but still obscure diversity. In this first attempt to uncover these biota in Brazil, we surveyed a restricted area within mountain chains in the southeastern region immersed in the Atlantic tropical forest, using several sampling methods along an elevational gradient. Using integrative taxonomy, we found a richness eight times higher than the current number of species known in Brazil, including 13 genera, of which 10 are new to the country. The 127 molecular taxonomic units found represent an increase of at least 50% in species for the Neotropical fauna, confirming the immense gap in taxonomic knowledge of this group in the Neotropics. Analyses of elevational gradient patterns of distribution indicated an increase in species elevational ranges with increasing elevation, supporting Rapoport’s rule. A key including all 14 genera occurring in Brazil is proposed, aiming to facilitate future taxonomic reviews and encourage research on this group. Orthocentrinae is a major component of the fauna and likely to be more diverse in wet lowland tropical forests; however, taxonomic and faunistic studies in tropical areas, including dry forests and savannahs, are needed.

Authors: Das Subhashish , Kumar ML Harendra
Published: August 2022

Introduction:

Extension of the shelf life of platelets remains a challenge for transfusion services, and efforts techniques are required to extend the shelf life of platelets beyond 5 days without compromising their qualities.

Materials and Methods:

The study is being done to compare in vitro changes of platelet indices-platelet count, mean platelet volume, platelet distribution width (PDW), pH and swirling in stored platelet concentrate (PC) with and without platelet additive solution (PAS) for 0,3,5,7 and 10 days.

Results:

Serial measurements of various parameters in PCs with and without PAS showed that PCs stored in PAS were better maintained and had optimal quality standards throughout the extended storage time as compared to the PCs without PAS. The results obtained in both categories were statistically significant (P < 0.001).

Conclusion:

Our study showed that the use of PAS in the PCs increased the shelf life and improved the viability of platelets as compared to the PCs without PAS.

Dropout rates and its correlates among the elderly patients attending a community health center
Authors: Mehra Aseem , Grover Sandeep , Avasthi Ajit
Published: August 2022

Aim:

The current study aimed to evaluate the dropout rates and the reasons for dropouts among elderly patients presenting with mental health problems to a community health centre.

Methodology:

This naturalistic, longitudinal, follow-up study was carried out in the Outpatient Setting of a community health centre in North India. The study included 169 patients, aged ≥ 60 years diagnosed with mental health problems. They were assessed at the baseline and then followed for a period of 1 year. Those who dropped out from the outpatient clinic were contacted over the phone to evaluate the reasons for dropout from treatment.

Results:

The mean age of the participants was 67.6 years and the mean number of years of education was 2.9. Most of the patients were female, married, Hindu, unemployed, from lower socioeconomic status, and non-nuclear families. The most common diagnosis was that of depression (42.6%), and this was followed by somatoform disorder (11.2%). The mean age of onset of psychiatric disorder was 62.2 years, with a mean duration of illness being 30.3 months. Nearly half (53.3%) of the patients dropped out of treatment after their first visit and 90% dropped out by 1 year. Overall the most common reason of drop out was complete relief of symptoms, and this was followed by the presence of family problems, and farming-related work. Among the very early drop out (never returned to clinic after the first visit) the most common reason for dropout was complete relief in symptoms, followed by inability to follow up due to family problems, no relief in symptoms, and farming-related work. Among those who dropped out within 6 months, the most common reason was complete relief of symptoms followed by lack of time due to personal reasons. When the reason for “late” dropout (dropout between 6 to 12 months) was evaluated, the most common reason was complete relief of symptoms followed by an inability to follow up due to problems in the family.

Conclusion:

A significant number of elderly patients with mental health-related problems drop out of treatment prematurely. Psychoeducation about the illness, outcome, and course of illness should be done at each step, and prevailing psychosocial issues need to be evaluated to reduce the rate of dropout among elderly patients with mental health-related problems attending the community health centre.
Changing Treatment Paradigms of Radiotherapy for the Treatment of Lung Cancer
Authors: Katano Atsuto
Published: August 2022

Lung cancer is largely classified into two types according to its histology, small cell and nonsmall cell, and has diverse situations for which radiotherapy is indicated. Radiation therapy plays a major role in the treatment strategy for both types of lung cancer. Since the treatment of lung cancer is extremely complex, it is essential to develop an appropriate treatment strategy by combining surgery, radiotherapy, and systemic therapy (chemotherapy, immunotherapy, and molecular-targeted drugs) according to each stage of the disease. Radiotherapy is indicated, from curative intent to palliative treatment, at any stage of the disease. Current radiotherapy, which incorporates diagnostic imaging and physical engineering, has made significant progress, making it possible to increase the local control rate while reducing the radiation dose to at-risk organs. Herein, we review the basics of the current perspective of radiotherapy and the current role of radiotherapy in lung cancer treatment according to each stage of the disease.

The Role of Practical Approach on Students’ Engagement in Biology: A Case of Lower Secondary Schools in Rulindo District, Rwanda
Authors: Tuyishime Jean Pierre , Tukahabwa Dorothy
Published: August 2022

This study explored the role of practical biology activities on student engagement in lower secondary school in Rulindo District. A sample of 84 students from 3 schools and 3 biology teachers was purposively selected from three lower secondary schools. Data was analyzed through descriptive statistics. The study established that biology practical lessons enhanced active interaction and immense support from teachers. Student engagement was higher and their performance was much better in practical than in non-practical options. Therefore, practical classes yielded better learning outcomes than the non-practical classes. Based on the findings, the study recommended that in order to stimulate students’ interests and better learning outcomes, teachers should use practical activities while teaching biology lessons. Students should be encouraged to develop interest in and to be familiar with practical activities. Much attention should be given to practical work in biology and all required resources for the implementation of practical activities should be made available. Finally, practical activities should be effectively planned and clearly structured for better learning outcomes to be realized.

This study was conducted for identifying the challenges confronted by Physics teachers during the implementation of competence-based curriculum (CBC) using inquiry-based teaching and learning (IBTL). It was qualitative by nature and it used a case study design. Semi-structured interview was used to collect data.  It involved a sample of three teachers selected purposefully from physics teachers of 50 lower secondary schools of Gakenke District located in Northern Province of Rwanda. Data were analyzed using thematic analysis. The findings from the study revealed that the participants of the study met with number of challenges during the implementation of physics competence-based curriculum using IBTL. Those challenges include the lack or insufficiency of teaching-learning materials and infrastructures, shortage of time, poor English language of students, beliefs of students that physics is difficult subject and the lack of teachers’ skills and knowledge to prepare inquiry-based lesson. The participants of the study are recommended to improvise local available teaching materials for effective use of IBTL. Policymakers are recommended to organize regular trainings of teachers at schools levels on how to plan inquiry-based lesson for effective implementation of physics CBC.

The present study isolated and characterized knipholone from the active 80% methanol rhizome extract of a traditionally used endemic antimalarial plant of Ethiopia, Kniphofia insignis Rendle, using preparative thin-layer chromatography for the first time. The chemical structure of the compound was elucidated on the basis spectroscopic data and in comparison with previously reported results. The standard 4-day suppressive test against Plasmodium berghei infected Swiss albino mice was used for the in vivo antimalarial assay of the extract. At all tested doses, the extract showed significant inhibition of parasitaemia. In particular, the extract demonstrated  chemosuppression values of 24.35 and 43.87% at 200 and 400 mg/kg, respectively. Results of the current study revealed that the extract of the plant has moderate in vivo antimalarial effect against P. berghei in mice.

Purpose: The study aims to investigate the antibiotics susceptibilities of isolates from eye swabs of babies delivered through Spontaneous Vaginal (SVD) and non- elective Caesarean Section (CS).Materials and Methods: This was a three-month prospective cross-sectional study, with samples as eye swabs of new born babies delivered in the maternity ward of Aminu Kano Teaching Hospital. Samples were collected not more than 30 minutes after delivery from 82 neonates (50 SVD and 32 CS) and stored in the refrigerator. It was evacuated in ice pack containers in batches within 24 hours to the microbiology laboratory for culturing, characterisation and sensitivity.Results: The result showed that E. coli was isolated in 25(30.5%) of the samples, P. aeruginosa, 22(26.8%), S. aureus, 21(25.6%) and K. pneumoniae 14(17.1%). In the SVD group, E. coli was isolated in 16(32%) of samples, P. aeruginosa, 14(28%), S. aureus, 11(22%) and K. pneumonia, 9(18%). In the CS group, S. aureus was isolated in 10(31.3%) samples, E. coli, 9(28.1%), P. aeruginosa, 8(25.0%) and K. pneumonia, 5(15.6). There were 47(77%) SVD and 14(23%) CS samples that were resistant to three (3) or more antibiotics but this difference was not statistically significant (p=0.157). Babies born through SVD had higher bacterial isolates when compared with those delivered through CS, but this was also not statistically significant (p=0.787).Conclusion: The mode of delivery had non-significant association with bacterial isolates from eye swabs of new born babies. We recommend Randomized  Controlled Trial to establish the risk of bacterial isolates in new born babies’ eyes.
Estimation of losses and efficiency of double-stator switched flux permanent magnet machines

Losses such as rotor iron and stator iron losses, magnet eddy current loss, as well as efficiency of a double stator permanent magnet machine having varying rotor pole numbers is estimated and presented in this study. This current investigation would be vital for electrical machine designers in quantifying the amount of losses in the various sections of a given double stator electric machine and as well provide better insight on resulting output efficiency of the machine. Time-stepping finite element analysis (TS-FEA) procedure is adopted in the calculations using ANSYS-MAXWELL simulation software. The compared machines having the same stator teeth/pole number (Ps) and different rotor pole (Pr) numbers are designated as: 6Ps/10Pr, 6Ps/11Pr, 6Ps/13Pr and 6Ps/14Pr. The predicted total loss values at rated current and operating base speed is 13.02 Watts, 13.13 Watts, 13.539 Watts, 13.537 Watts, from the 6Ps/10Pr, 6Ps/11Pr, 6Ps/13Pr and 6Ps/14Pr machine types, respectively. The corresponding efficiency of the machine types at rated working conditions is: 81.76%, 88.17%, 86.95% and 78.61%, respectively. The results show that magnitude of losses in a given machine would largely depend upon factors such as number of rotor poles and hence, the machine’s operating speed, electric loading and angular rotor position of the machine, etc. It is also found that the number of loss waveform cycles (Nc) in an electric revolution of the investigated machine would depend upon its stator and rotor arrangements. The most performing compared machine types are the ones that have 11- and 13-rotor pole numbers, while the least amount of efficiency is obtained from the machine type that has 14-rotor pole number. Above all, the 6Ps/10Pr and 6Ps/14Pr are characterized with high amount of pulsations or ripples and this is detrimental to the overall performance of the machines.
Manual removal of irregular-shaped foreign body lodged in the pharyngolaryngeal area in 4-months-old puppy

Published: August 2022

Choke in the veterinary profession is a term used to denote an obstruction to the passage route of food through the pharynx and oesophagus, either partially or completely. This case report describes a four-month-old male puppy, a Nigerian indigenous breed of dog weighing 6kg, diagnosed with oesophageal obstruction caused by ingestion of a fried chicken scapular bone. The puppy was presented at the emergency unit of the University of Jos Veterinary Teaching Hospital, where it was clinically evaluated, diagnosed and managed via manual removal of the dislodged bone that was performed with sterile thumb forceps under deep sedation. Reducing the incidence of foreign body obstruction in dogs can be achieved by ensuring that dogs are not fed with large, irregularly shaped bone and/ or bones with sharp edges. The bones are correctly disposed-off in the environment. Furthermore, bones should not be fed to dogs where likely competition for the bone is likely as a choke at the pharyngolaryngeal region can occur.
