A Comparative Study on Segmental Micro-Anatomy of the Human Fallopian Tube
Authors: Ramakrishnan Soumya , Kunjunni Kumari Thoppilparambil , Varghese Susan 
Published: January 2021

Background:
The Fallopian tubes serve as a bridge between the ovary and uterus and is divided into infundibular, ampullary, isthmic, and intramural segments from lateral to medial. Each segment is structurally and functionally equipped to perform specific functions. The maintenance of normal micro-anatomy of each segment is very important for successful spontaneous pregnancy. This study has compared the histological features of the isthmus, ampulla, and infundibulum.

Materials and Methods:
Tissue bits were taken from isthmus, ampulla, and infundibulum of Fallopian tubes of 100 women of reproductive age group and these were subjected to routine histological processing, and slides were stained with hematoxylin and eosin. The mean value of the number of primary mucosal folds and muscle thickness of each segment was calculated and compared with each other.

Results:
In the ampullary and infundibular region, there were primary, secondary, and tertiary folds with a mean value of 33.42 ± 4.49 and 31.53 ± 4.92, respectively. In the region of the isthmus, there were few primary mucosal folds with a mean value of 8.31 ± 0.9. The muscular layer was found thickest inthe isthmus with a mean value of 7.72 ± 0.76 mm and in the region of ampulla and infundibulum, the mean values were 4.39 ± 0.57 mm and 3.43 ± 0.48 mm, respectively.

Conclusion:
The ampullary region has maximum number of branching mucosal folds which ensure close contact with the developing embryo and provides nutrition. At infundibulum also there were numerous mucosal folds which help in accommodating the large number of ciliated cells which plays a major role in ovum pick up and transport as the muscle layer was found to be very thin in this region. The peristaltic contraction of thick muscle layer in the isthmus plays a very important role in the transport of embryo as only a few mucosal folds were found in this region.
Semiorthogonal decompositions of stable pair moduli spaces via d-critical flips
Authors: Toda Yukinobu 
Published: January 2021

We show the existence of semiorthogonal decompositions (SOD) of Pandharipande–Thomas (PT) stable pair moduli spaces on Calabi–Yau 3-folds with irreducible curve classes, assuming relevant moduli spaces are non-singular. The above result is motivated by categorifications of the wall-crossing formula for PT invariants in the derived category, and also by a d-critical analogue of Bondal–Orlov’s and Kawamata’s D/K equivalence conjecture.
We also give SOD of stable pair moduli spaces on K3 surfaces, which categorifies Kawai–Yoshioka’s formula proving Katz–Klemm–Vafa’s formula for PT invariants on K3 surfaces with irreducible curve classes.

Firm productivity, profit and business goal satisfaction: an assessment of maintenance decision effects on small and medium scale enterprises (SME’s)
Authors: Owusu-Mensah Daniel , Quaye Evans K. , Brako Lydia 
Published: January 2021

<p>This study was carried out to identify which factors are most relevant to managers of SMEs in maintenance decision making, and to investigate how these factors influence the realization of business goals satisfactorily, using structural equation modelling, partial least square design (PLS-SEM) to establish significant relationships between manifest and latent variables. A study of maintenance cost vis a vis the number of maintenance works carried out and profits realized was conducted to ascertain correlations and identify which factors played key roles in profit maximization. Results showed that with increasing level of maintenance for SMEs, profit margins reduced significantly. Also, an R<sup>2</sup> value of 0.83 showed that the latent variable, business goal satisfaction was explained to a high degree (83%) by the manifest variables. Rentals of equipment from third parties (0.27), halting production (0.11) and outsourcing (0.39) were less considered for business sustainability per correlation coefficients than funds (0.79), and the possibilities to carry out both corrective (0.64) and preventive (0.58) maintenance works. F-square value greater than zero was realized (0.387) and this showed reliability of the both inner and outer models. These findings can be used in building a decision tool or framework that will best suit SMEs with high financial budget constraints.</p>
Vitamin D Deficiency in Pregnancy and Its Effect on Maternal and Perinatal Outcome
Authors: Kaur Harpreet , Sharma Sushmita , Verma Minni 
Published: January 2021

ABSTRACTBackgroundVitamin D deficiency is a common endocrinological problem. Maternal vitamin D insufficiency during pregnancy has been associated with many pregnancy-related complications like preeclampsia, gestational diabetes (GDM), preterm labor, and low birth weight (LBW). Maternal vitamin D deficiency can lead to poor skeletal growth and reduced bone mineral density in children.Aims and objectivesTo study the prevalence of vitamin D deficiency in antenatal women and to study an association between vitamin D deficiency and maternal and neonatal complications.Materials and methodsA prospective study of 100 antenatal women presenting to obstetrics and gynaecology OPD at GSMCH, Banur. Out of these, data from 94 women were finally analyzed. For the rest of the women, follow-up and intrapartum and neonatal details were not available, so they were excluded from the study.ResultsThe prevalence of vitamin D deficiency in the present study was 79.8%. The rate of small for gestational age babies (SGA) and oligohydramnios was significantly higher in the study group. There was no significant difference in the incidence of GDM, preterm labor, and preterm premature rupture of membranes (PTPROM).ConclusionAntenatal vitamin D deficiency is associated with hypertensive disorders of pregnancy (HDP), SGA, oligohydramnios, and LBW. So, routine vitamin D supplementation should be recommended in the antenatal period.How to cite this articleKaur H, Sharma S, Verma M.

Sperm Abnormalities: In the Male Partners of Infertile Couples from Kanyakumari District
Authors: Viswambharan Neena , Manavalan Murugan 
Published: January 2021

ABSTRACTBackgroundInfertility has been identified as a health issue worldwide and it is of great concern among married couples in our society. Scientifically, it has been established that both males and females can contribute to infertility. However, in most cases, women are held responsible for the same without proper diagnosis. Statistically, female factors contribute to about 40–60% of infertility cases, whereas 20–40% of infertility cases are due to factors contributed by males, of which, deficiency in semen quality is the major cause which accounts for 40–50% of infertility cases. A decrease in semen quality has been reported which can be due to lifestyle changes, occupational exposures to chemicals, heat, and stress.AimsTo study the prevalence of infertility, distribution of sperm abnormalities, and the impact of occupation on men visiting a tertiary clinic.Settings and designMale partners of infertile couples who visited the fertility center were considered for the study.Materials and methodsSeminal fluid was analyzed for volume, sperm concentration, motility (progressive motility), and morphology.ResultsIn this study conducted in our center, we found that 55.8% of the patients had sperm abnormalities, among which teratozoospermia was the commonly observed anomaly.ConclusionMale factors equally contribute to infertility as female factors. Semen analysis is the crucial diagnostic test for infertility assessment of the male partner.Key messagesThe incidence of male infertility has been increasing recently and the evaluation and prognosis of male subfertility are challenging. Although semen analysis is the primary test for the assessment of infertility in males, it does not recognize the abnormality in idiopathic infertility. Thus, new techniques and methods need to be developed to improve accuracy and reduce variation.How to cite this articleViswambharan N, Manavalan M.

Authors: R. Mallari Alfred , V. Bagunu Jacqueline 
Published: January 2021

This study generally aimed to make an inventory of fishes in Candaba Swamp and documented the fishing practices of the local fishermen as they are related to their income. The study documented 14 different species of fishes, each representing 14 families in the Barangays of San Agustin and Dukma Paralaya. The fourteen species were the Elopshawaiensis, Glossobiusgiurus, Megalops cyprinoides,Cyprinuscarpio, Trichopodus pectoralis, Clariasbatrachus, Hypostomus plecostomus, Arius dispar, Hypophthalmichthys molitrix, Anabas testudineus, Carassiuscarasius, Labeorohita, Hypophthalmichthysnobilis,
Oreochromis niloticus. The Inventory recorded the Tilapia,Common Carp and Hito species as the most dominant species in Candaba Swamp. Fishermen’s ages were between 20 to 89, most of them were between 50-59, used the “panti” (kitig) as fishing gear and with daily income ranging from 100 pesos to 1,500 pesos. The total income of the fisherman during the wet season is from 1,000 pesos to 10,000 pesos, and the daily expenses in each fishing trip is from 20 pesos to 100 pesos which is mostly used for gasoline. The fishermen’s income depended on the number of fishes they catch which was affected by changes in season. The Cost-Benefit-Analysis showed a net income Of P281.27 per day with a Return of Investment of 174.4%.
Pesquisa-formação sobre fake news numa perspectiva crítica: discurso anticiência
Authors: Silva Lucinalva de Almeida , Marcelo Silva de Souza Ribeiro  
Published: January 2021

Resumo
Objetivamos neste escrito apresentar um recorte acerca de uma pesquisa-formação que tematizou a questão da fake news e da desinformação desenvolvida com um grupo de doze professoras dos anos finais/Ensino Fundamental no município de Afrânio-PE. Para tanto fizemos um recorte da pesquisa maior, discutindo um dos seis encontros. Embasamo-nos numa perspectiva crítica que dialogou com Freire (1996), Santaella (2019) e Valente (2019). A pesquisa traz a abordagem qualitativa interpretativa, do tipo pesquisa-formação. Como dispositivos recorreu-se a entrevista coletiva, a partir de técnicas grupais. Inferiu-se que o encontro descrito evidenciou a importância de se desenvolver a consciência crítica e participativa nos docentes e discentes visando o enfrentamento a pós verdade, “fake news” e comunicação saudável, unindo educação crítica ao diálogo, indo assim de encontro ao discurso anticiência gradualmente, pois o processo é paulatino e exige planejamento e ações sincronizadas.

Limping Across Borders in the Night of Self-Consciousness: Postmodernist Themes of Alterity in Cormac McCarthy’s No Country for Old Men and an Li’s Shi Jian de Miankong
Authors: Comprone Raphael J. 
Published: January 2021

Abstract
Cormac McCarthy’s American neo-noir neo-Western crime thriller No Country for Old Men and An Li 安黎’s black comedy Shijian de miankong 《时间的面孔》 (Time’s Visage) highlight the precipitous arc of decline in modern society through populist fantasies that exclude the Other. An Li’s 天立本 (Tian Liben) is a returning overseas Chinese who invests in a rubber factory to bring prosperity to his hometown. His dream turns into a nightmare when he discovers that pollution from the rubber plant has caused the villagers to die from cancer. Shaun Hu 拴虎, a corrupt official who helped Liben invest in the rubber plant, beats Liben, and the villagers want to avenge their dying family members. As a result, Liben eventually commits suicide. On the other hand, in No Country, Anton Chigurh is a cold-blooded and implacable hit man who incarnates Sheriff Ed Tom Bell’s worst imaginings. Unlike An Li’s Liben who is emasculated at the end of Time’s Visage, Chigurh is an indomitable nonwhite Other incarnating populist fears. Both writers describe a profoundly pessimistic universe in which the Other wreaks havoc.
Paul Auster, Orhan Pamuk, and the Postmodern Allegory in a Global World
Authors: Degirmencioglu Nesrin 
Published: January 2021

Abstract
Paul Auster’s City of Glass and Orhan Pamuk’s The Black Book both generated critical reception from deconstructive and poststructuralist angles. In this article, by pursing a historical materialist analysis, I explore how these postmodern city novels of the 1980s, which emerge from drastically different geographic, political, and cultural circumstances, respond to the impositions of global economic dynamics. In this context, I argue that the conflict between the apparent freedoms of globalization and the increasing entrapment of the postmodern subject constitutes the main dilemma of postmodern aesthetics. Auster’s City of Glass and Pamuk’s The Black Book register this postmodern dilemma in their respective forms through recourse to the metaphor of the “city as illegible text” and to the broken signifying systems of postmodern allegory. Focusing on these two literary techniques, I examine their differential appropriations in the core and the periphery of the world literary system in order to gauge how the experience of urban modernity—as shaped by particular cultural, social, and economic developments—contributes in turn to the shaping of literary form.
Word-initial rhotic avoidance: a typological survey
Authors: Labrune Laurence 
Published: January 2021

This paper addresses the issue of word-initial rhotic avoidance (WIRA) from a typological point of view. Its first aim is to document WIRA cross-linguistically, based on the examination of a sample of 200 languages designed by the WALS (Dryer and Haspelmath 2013). This set of 200 languages has been surveyed in order to reveal rhotic (and more generally liquid) phonotactic patterns in relation to word-initial avoidance. On the basis of this survey, the paper identifies two types of WIRA: i) phonological, or emic-WIRA; and ii) phonetic, or etic-WIRA. The first and most notable result of this research is that 49% of all languages containing at least one phonemic rhotic exhibit some degree of emic-WIRA, i.e, they possess no word or very few words beginning phonologically with at least one of their rhotics in their native lexicon. The paper also examines how word-initial rhotics are adapted from a non-WIRA language into a WIRA language. The loanword adaptation data suggest that WIRA is a recessive feature because no language in the sample has been observed to develop WIRA due to language contact (although one exception, Gascon, has been identified outside of the 200-language sample). Finally, the paper proposes two new universals in relation to WIRA: 1) if a language forbids /l/ word-initially, it also forbids /r/; 2) a rhotic segment never occurs as the positional allophone of a non-liquid segment word-initially.
