Assessment of 25-hydroxyvitamin D vitamin concentration in pre- and postmenopausal women
Authors: Kołodziejczyk Marlena , Stacherzak-Pawlik Jolanta
Published: February 2021

The analysis of vitamin D status revealed, that the concentration of 25-(OH)D: lower than 20 ng/ml and 30 ng/ml was found in 40% and 60% of the population, respectively. A majority of Polish society deal with the deficiency of vitamin D during winter and early spring. The aim of the study was to analyse 25-(OH)D in women, aged 40 years old or greater, who did not take vitamin D supplementation in winter months (September 2015 – February 2016). The assay results were acquired from DOLMED S. A. in Wrocław, Poland. The research was carried on the population of 380 patients. Measurements relied on Cobas (Roche) electrochemiluminescence immunoassay. Low concentrations of 25-(OH) D were divided into three types: mild deficiency, deficiency, hypovitaminosis. Low vitamin D concentration (<30 ng/ml) was found in 59.2% of the population. Reference values of concentration were observed in 39.2% of the population, whereas 1.6% – suffered from hypervitaminosis. In women, aged 50 years old or less (premenopausal period), a correlation was found between serum vitamin D concentrations and months in which the research was carried on. In women, aged over 50 years old (postmenopausal period), this correlation was not shown.

Introduction: The aim of the study was to assess the prognostic value of indicators calculated on the basis of initial hematology test results of neutrophil, lymphocyte, monocyte and platelet counts (NLR – neutrophil-to-lymphocyte ratio, LMR – lymphocyte-to-monocyte ratio, PLR – platelet-to-lymphocyte ratio) in patients with ovarian cancer and their compliance with the overall response to treatment. Materials and methods: Hematological tests were performed before first course of first-line chemotherapy in 145 patients with ovarian cancer. Response to treatment was assessed according to the RECIST1.1 criteria in all patients. Results: After the completion of first-line treatment, 70 (48.3%) patients had a complete response (CR) to the therapy. In this group, progression of disease occurred in 22 (31.4%) patients during 12 months of follow-up. In the CR group with progression, 17 (77.2%) presented high NLR and PLR levels. Among 48 (68.6%) patients with CR without progression after 12 months of follow-up, high levels of NLR and PLR were observed in 21 (43.8%) and 17 (35.4%) of them, respectively. Low LMRs were observed in 16 (72.7%) patients with progression and 16 (33.3%) without progression. Conclusion: High levels of NLR and PLR and low levels of LMR before treatment seems to predict 12-month disease progression in patients with complete response to first-line treatment.
Basic diagnostic tests of IgE dependent and contact allergy
Authors: Butrym Iga , Płaczkowska Sylwia , Pawlik-Sobecka Lilla , Smolińska Sylwia
Published: February 2021

Allergy is a hypersensitive immune response against non-pathogenic external factors that either enters the body or have a direct contact with the skin or mucosa. Diagnosis of allergy is a complex, multi-stage process in which the main role plays medical history analysis of the disease and its confirmation by additional tests, such as skin tests and allergen-specific IgE serum antibody assays. Skin tests can be used, with variable success, in diagnosis of all allergies. However, they have the greatest significance in diagnosing of contact and inhalation allergies. In the diagnosis of atopic, when skin tests are impossible or their results are not consistent with the interview, measurement of serum IgE levels may be very helpful. Determination of specific antibodies is very important in the diagnosis of allergy to insect venom and latex, it could bring supplementary information to food allergies diagnosis. The choice of method therefore depends on the allergy diagnosis and the current knowledge about the sensitivity, specificity and predictive value of the test used, as well as the data obtained in the medical examination, which remains are basis method in allergy diagnosis.
Tests in the point of care – glucose meter as a POCT tool. Implement a quality system control
Authors: Stacherzak-Pawlik Jolanta , Rak Alina , Smaciarz Joanna , Jasińska Krystyna
Published: February 2021

Introduction: Point of care testing (POCT) are tests carried out near to the patient, outside the laboratory. There is a continuing increase interest in POCT, however the issue of quality of those tests rises concerns. Glucose concentration measurements are carried out using glucometers, which makes those analyzers a POCT tool. All devices outside the laboratory should be included in internal quality control system according to ISO 22870, so it is necessary to control glucometers as well.
Aim: To perform the quality control of glucometers as a POCT tools in University Hospital in Wroclaw, evaluate the correct use of glucometers, conduct replacement of devices, and implement constant internal quality control.
Materials and methods: The approximate count of blood glucose measurements in the hospital was determined on the basis of laboratory data and glucometers strips orders. Quality control was performed using MediSense certified control materials at two concentrations levels. A total of 272 control measurements were used for interpretation, which were made on 25 FreeStyle Optium H glucometers. The results were registered in quality control sheet.
Results: Laboratory determinations of glucose concentration represented 24.6% of all glucose measurements, POCT tests 75,4%. Among control measurements 80.88% were within ± 15% error recommended by Polish Diabetology Association and 19.12% exceeded it, 7.35% exceeded ± 20%. However none measurement exceeded the error recommended by glucometer manufacturer.
Conclusions: Based on our results several glucometers were replaced and the systematic internal quality control was introduced. Numerous of glucometer training courses for medical staff were conducted.
Molecular mechanisms controlling the biological clock
Authors: Sitkiewicz Dariusz , Sygitowicz Grażyna
Published: February 2021

This year’s awardees of the Nobel Prize in Physiology or Medicine – Michael Rosbash, Michael W. Young and Jeffrey C. Hall discovered genes responsible for controlling the biological clock. Their studies allowed to form the basic mechanism of the Transcription– Transla- tion Feedback Loop, known as TTFL. The transcription of the PERIOD gene and its partner TIM is inhibited by proteins encoded by them which are generated oscillatorily and autonomously.
The biological clock controls many physiological processes by generating circadian oscillations in harmony with day and night patterns. The daily rhythm regulates sleep, eating meals, hormone release, blood pressure and body temperature.

Congenital hypothyroidism is a cause of mental retardation and has nonspecific signs and symptoms. Early diagnosis and treatment are essential for the normal development of children affected by this disorder. The objective of this study was to evaluate theincidence of changes in the screening tests of public hospitals in Presidente Prudente, the average age of the newborn at the time of collection of tests and confirmation of the diagnosis. A retrospective cross-sectional study was carried out to assess the data of newborns who underwent the “heel prick test” by the unified health system in 2017. Of the 3,351 evaluated, 48 had elevated levels of Thyroid Stimulating Hormone(TSH), 13 had the diagnosis confirmed congenital hypothyroidism. It was 61.54% the children that returned between days 16 and 30 to confirm the result and 23.07% that returned after 61 days. Early diagnosis and treatment is essential, as they enable mitigating actions for the serious cognitive and behavioral disorders of affected patients.
Aspectos da difusão de covid-19 na região geográfica imediata de Imperatriz, Maranhão, Brasil
Authors: Oliveira Allison Bezerra , Madeira Alberto Soares , Paz Diego Armando de Sousa
Published: February 2021

O presente trabalho tem por objetivo discutir aspectos da difusão da covid-19 na região geográfica imediata da cidade de Imperatriz, no estado do Maranhão. O período analisado compreende os 100 primeiros dias de pandemia no estado. São considerados dados da espacialização de UTIs, leitos hospitalares e respiradores/ventiladores mecânicos no estado, bem como informações sobre a evolução viral e procedência geográfica de pacientes nesse período. As principais fontes de dados são o Datasus e a Secretaria de Estado da Saúde do Maranhão. Os aspectos estudados sugerem que a concentração de equipamentos médico-hospitalares em Imperatriz, configura-se como expressivo gargalo no enfrentamento da pandemia de Sars-CoV-2, na medida em que desencadeia fluxos de pessoas de centros com menor oferta de serviços em busca de atendimento médico, resultando em amplas áreas de contágio além de distorções quanto a origem geográfica dos casos.
Refinamento de modelos de navegação de robôs autônomos através da calibração do sistema de odometria
Authors: Cândido Rafael da Paixão , Oliveira Gina Maira Barbosa de , Martins Luiz Gustavo Almeida
Published: February 2021

Técnicas bio-inspiradas têm sido investigadas no planejamento de rotas em modelos de navegação de robôs autônomos. Dentre essas técnicas, os autômatos celulares (ACs) se mostraram uma opção descentralizada e de baixo custo computacional. A partir do estudo de modelos de navegação baseado em ACs publicados previamente, percebeu-se que o uso de ambientes formados por células do tamanho do robô e-puck resulta em trajetórias com colisões. Neste trabalho, um método de calibração da odometria foi integrado a esses modelos a fim de garantir uma trajetória mais precisa. Simulações mostraram que o método adotado foi capaz de melhorar a trajetória no cenário avaliado. O robô não só chegou mais próximo da célula objetivo, como também apresentou uma trajetória mais próxima da ideal e totalmente livre de colisões.
The dynamics of class mobilisations: evidence from protest event analysis in Bulgaria and Slovenia
Authors: Dinev Ivaylo
Published: February 2021

Following the recent interest of bringing capitalism back into social movement studies, this article contributes to the debate with the application of new techniques for examining the dynamics of social class in protest politics. Questioning the declining importance of labour mobilisation in the recent anti-austerity cycles of protest in eastern Europe, I draw on a unique protest event dataset to propose a new way of exploring the relations between social class, repertoires and claimmaking. I show that this innovation can bring greater clarity to a systematic analysis of social class politics in the protest arena. The empirical exploration highlights that more than one-third of the protest events in Bulgaria and Slovenia in the aftermath of the financial crisis were driven by specific social class actors. The article suggests that, contrary to individual-level data, social class can be observed through the basic conceptions of workers and independents; and then through site and sector: production; services; and socio-cultural. These typologies help in understanding where mobilisations arise, under what conditions and for what demands.
State and policy failure concerning refugees in Bulgaria: Dynamics, trends and paradoxes
Authors: Otova Ildiko
Published: February 2021

The change of political regime in Bulgaria after 1989 drastically altered the country’s migration picture. It can be asserted positively that the number of emigrating individuals still exceeds the number of immigrants who have made their choice of Bulgaria as a country of reception. However, material provided by researchers, demonstrating that immigration is radically different from the classical phenomenon in western Europe, is at sharp variance with the manner in which the topic has been reflected in the domestic political and public discourse. This article examines the refugee phenomenon of Bulgaria against this context, seeking to highlight the failures of Bulgarian politics and policy development process. Politicians have ruthlessly exploited the topic in their desire to generate an everpresent sense of crisis, and crisis management, which not only covers up their own shortcomings but also acts to prevent the making of real policies, creating a gap into which NGOs have been forced to step. These, in turn, pose the real threat to national security insofar as Bulgaria remains unprepared to face subsequent migration.
Thinking the Event in Heidegger’s “Black Notebooks”
Authors: Galanti Grollo Sebastiano ,   DePaul University
Published: February 2021

In this essay I examine the concept of the “event” in Heideggerian thought, with particular reference to the first volume of the Black Notebooks, which is contemporaneous with Contributions to Philosophy (Of the Event) (1936–1938) and Notes III (dating from 1946–47) from the fourth volume. At issue are the concepts of “event” (Ereignis), “essential unfolding” (Wesung), and “expropriation” (Enteignis), which assume considerable importance in the mid-1930s. Through his treatment of the event, Heidegger reinterprets being as an alterity with respect to beings and to Dasein, in that being withdraws and conceals itself. Furthermore, I show a shift in Heidegger’s “disposition” (Stimmung) that occurs in Notes III, from an “attunement” that stresses decision to a way of thinking in terms of “releasing” and “thanking.” In these writings, Heidegger already makes use of the concept of “releasement” (Gelassenheit), which is usually associated with a later stage of his thought.

Authors: Lopez Evelyn da Costa Martins Silva , Cruz Elaine Drehmer de Almeida , Alpendre Francine Taporosky , Batista Josemar
Published: February 2021

Objetivo: analisar a cultura de segurança em unidades cirúrgicas de três hospitais de ensino paranaenses. Método: survey, transversal, com coleta de dados realizada entre 2017 e 2018, em três hospitais com administração federal, estadual e privada. Utilizou-se o questionário Hospital Survey on Patient Safety Culture, que analisa 12 dimensões da cultura de segurança; aquelas com índices ≥75% foram consideradas fortalecidas. Resultados: a dimensão “trabalho em equipe dentro das unidades” foi identificada como fortalecida no hospital privado (77,8%); nos demais, nenhuma dimensão mostrou cultura fortalecida. Os profissionais do hospital privado externaram, significativamente, percepção menos negativa em seis dimensões de cultura. Comparados aos profissionais médicos, a Enfermagem apresentou percepção mais positiva, com diferença significativa para quatro dimensões. Conclusão: a administração privada estimula a cultura de segurança, quando comparada à pública. As dimensões frágeis são expressivas em todos os segmentos de trabalhadores, tornando-se desafio para promover cultura positiva em unidades cirúrgicas de hospitais de ensino.
necessidades em saúde de usuários e sua interação com a atenção primária
Authors: Farão Elaine Miguel Delvivo , Penna Cláudia Maria de Mattos
Published: February 2021

Objetivo: compreender o significado das necessidades em saúde da vida cotidiana para os usuários da atenção primária à saúde. Método: trata-se de pesquisa qualitativa cujo referencial teórico foi o interacionismo simbólico, e o metodológico foi a teoria fundamentada nos dados. Foram entrevistados 23 usuários da atenção primária à saúde do município de Coxim-MS, no período de fevereiro a novembro de 2018. As entrevistas foram gravadas, transcritas e analisadas, sendo a análise concomitante a coleta de dados. A duração das entrevistas foi, em média, de uma hora. Inicialmente os participantes foram selecionados aleatoriamente. No decorrer da análise dos dados, foram sendo constituídos os grupos amostrais, com a finalidade de ampliar a variabilidade das concepções sobre o fenômeno. Os dados foram analisados por meio da codificação aberta, axial e seletiva. Resultados: as necessidades em saúde da vida cotidiana resultam da interconexão de três subcategorias, a seguir: a primeira, denominada “o autocuidado: cuidando do que eu podia cuidar” - self; a segunda, “os relacionamentos na sociedade - a interação com o outro”; e a última, “as relações com o espaço onde se vive - a interação com o ambiente”. Conclusão: constatou-se que as necessidades da vida cotidiana não são significadas em uma perspectiva interacionista, pelos usuários, como demandas que podem ser cuidadas nos serviços. Dessa forma, por se distanciarem das demandas biológicas, são negligenciadas pelos profissionais de saúde na atenção primária e refletem que o cuidado integral ainda permanece como desafio no âmbito do Sistema Único de Saúde.

Political motivation: A referent evaluation mathematical model
Authors: Rigoli Francesco
Published: February 2021

Mathematical modelling is popular in cognitive psychology because it enables clear and formal descriptions of the processes at play; yet, this approach has rarely been applied to political psychology. Here we adopt mathematical modelling to develop a theory of political motivation, which is a central concept in political psychology. The theory assumes that, in certain contexts, individuals entertain a set of representations of society, for example of the past, present and future (but also of fictive societies such as utopias). To each representation of society, an incentive value is attached which is not absolute, but (following theories of motivation in cognitive psychology) reference-dependent; namely, dependent on the context, corresponding to the whole set of representations of society. In turn, the model proposes that these subjective values determine two central aspects: a motivation for performing an appropriate political action and the ensuing political mood. We discuss the model with respect to theoretical and empirical research (and we examine Marx and Engel’s communist manifesto as an example of the latter). In short, we offer a new mathematical perspective on political motivation which emphasises the role of multiple representations of society in determining political motivation and the ensuing political mood.
Favouring a disunited Kingdom? How negative perceptions of the EU-referendum relate to individual mobility and collective action considerations
Authors: Ditrich Lara , Gedeon Edit Z. , Sassenberg Kai
Published: February 2021

One consequence of the EU-referendum’s pro-Brexit outcome was a renewed call for Scottish independence. Supporting this call can be construed as a form of collective action Scots may engage in. However, Scots may also consider individual mobility strategies including - in extreme cases - emigration. The current research investigated how identity-dynamics relate to these identity management strategies in post-referendum Scotland. We found a positive association between perceiving the EU-referendum as having violated expectations and considering individual mobility responses, mediated by identity subversion (i.e., the perception that the referendum results fundamentally changed the UK’s identity). Furthermore, we found that perceiving the EU-referendum as having violated expectations was related to higher collective action intentions, mediated by disidentification from UK citizens. Taken together, these findings underscore the pervasive role social identity processes play in shaping political decisions and individual behaviour.
Um crítico e uma prostituta: Incursões do pensamento em direção ao espectador qualquer
Authors: Souza Luiz Paulo Pimentel de
Published: February 2021

A partir da pergunta feita por Virginia Woolf em seu ensaio Como se deve ler um livro? e de seu vivo interesse pela figura do leitor comum, neste artigo deslocamos a análise do campo literário para o teatral de modo a problematizar a figura do espectador. Com o intuito de investigar as singularidades e potencialidades das quais o olhar do espectador comum (propositalmente enfocado aqui como espectador qualquer) estaria investido, o artigo mobiliza dois personagens: um crítico, descrito por Diderot em seu Discurso sobre a poesia dramática como um espectador ideal, e uma prostituta aficionada por tragédias gregas, interpretada pela atriz Melina Mercouri no filme Nunca aos Domingos, de Jules Dassin. Buscando diferir o olhar do espectador comum daquele que seria o seu extremo oposto, o especialista, especificamos dois procedimentos distintos presentes na relação entre o olhar e a obra: o gesto hermenêutico, articulando o saber a partir de um campo transcendental, e o gesto-qualquer, recusando exterioridades e fundando um espaço de imanência.
The Smear Layer Removal Efficiency of Different Concentrations of EDTA in primary teeth: A SEM Study
Authors: DEMİREL Akif
Published: February 2021

Objectives: The present study aims to evaluate the effects of different concentrations of ethylenediamine tetraacetic acid (EDTA) on smear layer removal in primary teeth by using scanning electron microscopy (SEM).
Materials and Methods: The present study was performed with 28 extracted upper primary incisors assigned into four main groups (n=7) as 5%, 10% and 17% EDTA, and 1% sodium hypochlorite (NaOCl). The root canal surfaces (coronal, middle and apical) were scanned by SEM and scores of smear layer removal were recorded and compared after the root canal irrigation procedures. The results were analyzed using Kruskal–Wallis, Friedman and Dunn tests.
Results: In all the root portions, although EDTA groups removed the smear layer more effectively than NaOCl, a statistically significant difference was observed between 17% EDTA and 1% NaOCl only in middle third (p <0.05). Also, smear layer was removed more effectively in coronal than apical in most of the groups (10% EDTA, 17% EDTA and 1% NaOCl) (p <0.05). Erosive defects were mostly seen in 17% EDTA and less than 10% EDTA group. These findings were not detected in 5% EDTA and 1% NaOCl group.
Conclusions: It is possible to recommend the use of 5% EDTA irrigation solution in root canal treatment of primary teeth due to its similar smear layer removal efficacy with NaOCl and high concentration EDTA groups, low erosive potential and low concentration for periapical safety.

Authors: KAPDAN Alper , KAYA Seher , EREN Digdem
Published: February 2021

Purpose: To evaluate the effect of two second generation LED Light curing units and a third-generation polywave LED Ligth curing unit at three different irradiation durations on surface microhardness and detpth of cure of nanofilled composite resin material.
Materials and Methods: EliparTM S10, EliparTM Deep Cure-S, VALO Cordless, was evaluated at 10s, 20s, 40s curing periods in this study. A nanofilled composite FiltekTM Z550 that contains camphorquinone as photoinitiator is used as test material. For microhardness test ninety 6 mm diameter, 4 mm deep cylindrical composite blocks in teflon molds were prepared. For each light source at each application times 10 specimen were prepared (n=10) and tested. Also ninety, 4 mm diameter, 6 mm deep cylindrical composite specimens in a split aluminum mold polymerized with three different light sources at three different durations (n=10) were tested for depth of cure measurement. Data were analyzed statistically by SPSS (Ver: 22.0) and significance test of the difference between the two means (Kolmogorov-Simirnov), the variance analysis, and the Tukey Test used.
Results: The values of cure depth were found significantly higher at 40 seconds of irradiation time for all light sources used (p<0.05). Elipar Deep Cure-S showed the higher top surface microhardness at 40s polymerization (p<0.05)
Conclusion: All light devices used in the study provided adequate polymerization of the nanofill composite at all application durations in this study. The highest polymerization depth and microhardness values were achieved at 40 sec. polymerization time for all LCUs.s
A revised augmented Cuntz semigroup
Authors: Robert Leonel , Santiago Luis
Published: February 2021

We revise the construction of the augmented Cuntz semigroup functor used by the first author to classify inductive limits of $1$-dimensional noncommutative CW complexes. The original construction has good functorial properties when restricted to the class of C*-algebras of stable rank one. The construction proposed here has good properties for all C*-algebras: we show that the augmented Cuntz semigroup is a stable, continuous, split exact functor, from the category of C*-algebras to the category of Cu-semigroups.
Logarithmic concavity of the inverse incomplete beta function with respect to the first parameter
Authors: Askitis Dimitris
Published: February 2021

The beta distribution is a two-parameter family of probability distributions whose distribution function is the (regularised) incomplete beta function. In this paper, the inverse incomplete beta function is studied analytically as a univariate function of the first parameter. Monotonicity, limit results and convexity properties are provided. In particular, logarithmic concavity of the inverse incomplete beta function is established. In addition, we provide monotonicity results on inverses of a larger class of parametrised distributions that may be of independent interest.

Let $p$ be a prime. We show that if a pro-$p$ group with at most $2$ defining relations has quadratic $\mathbb{F}_p$-cohomology algebra, then this algebra is universally Koszul. This proves the “Universal Koszulity Conjecture” formulated by J. Miná{č} et al. in the case of maximal pro-$p$ Galois groups of fields with at most $2$ defining relations.

Echo and the Recovery of the Past in R. Murray Schafer’s The Princess of The Stars
Authors: Kinnear Tyler
Published: February 2021

Canadian composer and acoustic ecologist R. Murray Schafer is known for his outdoor works. Other scholars have considered the collaboration between musicians and the physical world in Schafer’s compositions and have linked performer-environment interaction with Canadian identity and environmentalism. Yet the role and meaning of outdoor acoustics in Schafer’s music remains understudied. This article investigates the aesthetics of echo in Schafer’s outdoor theatre workThe Princess of the Stars(1981–4). Echo not only sends an original sound back from a surface but also offers insight into the role that musical sounds play in prescribing an interpretation of nature.
ARTS-INSPIRED PRACTICE: FUELLING THE IMAGINATION
Authors: Wehbi Samantha
Published: February 2021

As we continue to contend with complex social problems, social work practice has witnessed the need to continue to grow in seemingly unfamiliar territory. Indeed, we have seen the rise in scholarship bridging between professional disciplines such as social work and the creative arts. As we begin to understand in more depth the links and potential cross-pollination between these seemingly divergent fields, it is important to begin to crystallize our approaches in ways that help guide our community practice. The article begins by summarizing the purpose of using the arts in professional practice and proceeds to proposing a typology to conceptualize arts-inspired approaches to practice. Specifically, I propose understanding the role of art as a potential catalyst, connector, and communicator. I also propose a methodology to guide interventions by examining the modes, means, and mediums that can take our theoretical understandings of the role of art to practical application. The paper ends with an invocation to heed our anxieties about taking creative risks in our practice, not by shunning them, but by welcoming them as a way to continually grow and evolve as practitioners.

Dinamitando la caja del misterio: el retorno de Twin Peaks
Authors: Roig Antoni
Published: February 2021

Sergio Ramos y Rafa Nadal están viendo Twin Peaks. No sé si habrán elaborado ya alguna teoría, pero probablemente se sientan desconcertados. Lo que Movistar+ anuncia como «No es una serie. Es la Serie» se ha revelado como algo distinto, que pone a prueba —y de qué manera— lo que significa ver televisión en esta llamada "era dorada" de las series. ¿Nostalgia? ¿Autohomenaje? ¿Control autoral férreo? ¿Caos y decadencia narrativa? ¿Gol a Showtime?… Aun no lo sabemos, pero este es precisamente el tema: David Lynch y Mark Frost han construido un artefacto radical que ejerce un influjo extraño pero que se niega a dar explicaciones y nos deja indefensos: ¿spoilers?, ¿teorías fan? Esto es otra cosa.
Comparing general and specialized word embeddings for biomedical named entity recognition
Authors: Ramos-Vargas Rigo E. , Román-Godínez Israel , Torres-Ramos Sulema
Published: February 2021

Increased interest in the use of word embeddings, such as word representation, for biomedical named entity recognition (BioNER) has highlighted the need for evaluations that aid in selecting the best word embedding to be used. One common criterion for selecting a word embedding is the type of source from which it is generated; that is, general (e.g., Wikipedia, Common Crawl), or specific (e.g., biomedical literature). Using specific word embeddings for the BioNER task has been strongly recommended, considering that they have provided better coverage and semantic relationships among medical entities. To the best of our knowledge, most studies have focused on improving BioNER task performance by, on the one hand, combining several features extracted from the text (for instance, linguistic, morphological, character embedding, and word embedding itself) and, on the other, testing several state-of-the-art named entity recognition algorithms. The latter, however, do not pay great attention to the influence of the word embeddings, and do not facilitate observing their real impact on the BioNER task. For this reason, the present study evaluates three well-known NER algorithms (CRF, BiLSTM, BiLSTM-CRF) with respect to two corpora (DrugBank and MedLine) using two classic word embeddings, GloVe Common Crawl (of the general type) and Pyysalo PM + PMC (specific), as unique features. Furthermore, three contextualized word embeddings (ELMo, Pooled Flair, and Transformer) are compared in their general and specific versions. The aim is to determine whether general embeddings can perform better than specialized ones on the BioNER task. To this end, four experiments were designed. In the first, we set out to identify the combination of classic word embedding, NER algorithm, and corpus that results in the best performance. The second evaluated the effect of the size of the corpus on performance. The third assessed the semantic cohesiveness of the classic word embeddings and their correlation with respect to several gold standards; while the fourth evaluates the performance of general and specific contextualized word embeddings on the BioNER task. Results show that the classic general word embedding GloVe Common Crawl performed better in the DrugBank corpus, despite having less word coverage and a lower internal semantic relationship than the classic specific word embedding, Pyysalo PM + PMC; while in the contextualized word embeddings the best results are presented in the specific ones. We conclude, therefore, when using classic word embeddings as features on the BioNER task, the general ones could be considered a good option. On the other hand, when using contextualized word embeddings, the specific ones are the best option.

Introduction: The most common causes of Abnormal Uterine Bleeding (AUB) in women of reproductive age are uterine polyps. Operative hysteroscopy is the management of choice to remove polyp. However, the certainty of the treatment remains to be examined. Aim: To investigate the outcome of hysteroscopy polypectomy in women with AUB. Materials and Methods: This was a cross-sectional study on the samples of women with AUB who underwent a hysteroscopy polypectomy. Patients were assessed pre and postoperatively and were asked to respond to a number of outcome measures including duration of monthly cycle, menstruation cycle, heavy menstrual bleeding, the number of pads used in day and night and improvement of inter-menstrual bleeding, postcoital bleeding, and limited activity. Pre-and postsurgery data were compared using Wilcoxon and McNemar tests. Results: In all, 83 patients were entered into the study. The mean age of participants was 41.8 (±8.37) years. The most common preoperative complaint was heavy menstrual bleeding (n=63, 76%) followed by intermenstrual bleeding (n=40, 48%). There were significant differences between preoperative and postoperative symptoms (p-values <0.05). Perceived complete recovery (n=54, 65%), partial recovery (n=13, 15.7%) and satisfaction (n=66, 79.5%) were high after hysteroscopy. Conclusion: AUB due to polyp might be improved with hysteroscopy. Further investigations are needed to confirm the results and to study on co-existence of other causes of AUB after hysteroscopy polypectomy.

Filipino children are put at risk with the increasing intake of junk foods which often resulted in health problems such as obesity, malnutrition, gastro -intestinal and urinary related illnesses such as constipation, stomach ulcers, urinary tract infection, kidney stone, and others, This Study was conducted to develop and validate a nutri- scie card game intended to foster awareness on healthy foods consumption among school children. The researcher made use of the Research and Development model by Borg and Gall with the following phases: identification of learning competencies; development of nutria scie card game; and validation of the nutri-scie card game by subject experts and experts in instructional materials development. Result of the validation revealed that Nutri-Scie Card game is highly valid. A significant improvement was noted in most food choices of the pupil respondents.

Zinc nanoparticles (ZnNPs) produced was evaluated against Alternaria burnsii to see the inhibitory result of the ZnNPs on the growth of fungal mycelium. Physical characterization of synthesized ZnNPs was 68.04 nm in size, Pdi- 0.263, Keps-252.4. Among the twelve treatments, the best treatment was synthesized ZnNPs with concentration (750 ppm) evidenced most in effect with 86.17 per cent mycelial growth is inhibited. The next treatment was synthesized ZnNPs with concentration (250 ppm) giving 79.26 per cent growth inhibition. Followed by treatment commercial ZnNPs with concentration (1000 ppm) giving 53.46 per cent growth inhibition. The next effective treatment was commercial ZnNPs with concentration (500 ppm) giving 44.69 per cent growth inhibition. Followed by treatment of carbendazim 50 WP with concentration (500 ppm) giving 11.51 per cent growth inhibition. The least effective treatment was commercial ZnNPs with concentration (100 ppm) giving 3.22 per cent growth inhibition. There is directly proportional relationship between increased concentration of the ZnNPs and inhibition of per cent mycelial growth of the pathogen is directly proportional. Further, methylene blue staining was done and the physical changes were studied. The hyphae lost their softness, bulges out followed by reduction in the distance between two hyphae. Branched conidia turned round and conidial development was suppressed. On the basis of this result it can be concluded that ZnNPs inhibited the fungal growth by causing physical damage to the fungal mycelium.

Onion (Allium Cepa L.) is cultivated globally as a one of the prominent vegetable crop. India is the second largest producer of onion in the world next to China, but still there is large of scope to enhance the production and productivity. In India, the cultivation of onion is not fully mechanized, only progressive farmers are using the machineries for cultivation. Therefore, it’s required the intensive labour, resulted low productivity with high cost of cultivation. Generally farmers are doing the manual sowing of seeds or manual transplanting system. To address this issue, a manual operated two row planter was developed for directly sowing the seed in prepared field. This machine can easily be operated by a single man/woman by pushing action while walking in the field. Evaluation of the machine was successfully performed in enclosed environment (i.e. laboratory) and on the grounds of some performance parameters that plays a crucial role in performance evaluation of machine. The parameters such as missing index, multiple index and quality of feed index were determined respectively that yielded numerical values of 11.5 per cent, 25 per cent and 63 per cent, respectively. On the basis of obtained results, it was easily justified that metering mechanism of vertical rotor type with dimensions of slot size 2.5 mm × 3 mm was most suitable for mechanical sowing of onion seeds having an operational speed of 2 km h-1 to obtain the optimum seed rate of 7-8 kg ha-1. The field capacity and field efficiency of the developed machine for sowing of onion seeds were found to be 0.042 ha h-1and 78 per cent respectively at the average operational speed of 1.8 km h-1. But as far as the labour requirement is compared, in instance of the onion planter, only 48 man-h are required for planting of 1 ha area, whereas in case of manual transplanting method, about 800-960 man-h are required for 1 ha area. The developed machine results in savings in terms of seed, labour requirement, inputs i.e. fertilizers, chemicals, water etc. by providing 15 cm of row to row spacing uniformly with an addition of 10 cm plant to plant spacing. Uniform crop establishment also enhance the mechanization of subsequent operations i.e. weeding, spraying and harvesting. The yield obtained by developed seed drill was 14.9 t ha-1which is very close to the yield obtained with manual transplanting of onion seedlings i.e. 15.6 t ha-1.
Opportunities for Enhancing Winemaking Processes by Employing High Power Ultrasonics Technology: A Review

Published: February 2021

High power ultrasonics (HPU) technology has been used in the food industry to develop effective methods for food production, and to reduce operational costs and improve product quality with large-scale commercial applications since the 1990s. While high intensity energy produced by HPU has been successfully applied to many processes in food production, its application to winemaking is still at an experimental stage. However, as a disruptive industry changer, HPU technology offers an enormous range of possibilities to improve the wine industry’s competitive position through lower cost, higher quality, and the delivery of cleaner, fresher, and more appealing wines to the customer. It will enable wineries to create more sustainable, transformative and innovative solutions to enhance winemaking processes.
