Published: May 2021

The use of Artificial Intelligence approaches as NPCs in games is a very common practice, as they seek to convey the impression to players that these characters are somewhat autonomous. One of the approaches used is the technique called NEAT, which consists of making use of artificial neural networks together with genetic algorithms to manage the topology, connections, and weights of a network in an adaptive way. This work presents the proposal to create an NPC for games in a subcategory of board games, those based on bluff and incomplete information. The game used as a case study is One Night Ultimate Werewolf, a social deduction game, so that information is incomplete for players, and part of them must use the bluff in order to confuse other players. The objective is to evaluate the possibility of modeling the behaviors of this type of game for the application of NEAT.

Published: May 2021

Analyzes of scientific collaboration networks have been extensively explored in research from different areas of knowledge, in view of their ability to identify how groups of researchers have carried out their work collectively. Such studies make it possible to identify how collaboration between individuals occurs through analyzes based on social network metrics. In this context, new studies have been proposed in order to analyze collaboration in the development of technical products, with data on patents being studied in most studies. This type of analysis is relevant because it makes it possible to understand the collaboration process in the proposal of new inventions. In this work, initially a general characterization of the group of individuals analyzed is presented, and afterwards, a global and temporal analysis of the collaboration network is performed in the proposal of patents of Brazilian individuals with curricula registered in the Lattes Platform. For that, all the patents registered in the curricula of these individuals were used for the identification and characterization of the collaboration networks. As a result, it is possible to see how collaboration in the proposed inventions of the analyzed set has been intensified over the years, with an emphasis on the institutions and areas of expertise of each inventor.

Published: May 2021

RESUMOO presente trabalho se propõe a analisar, sob a perspectiva da garantia constitucional da igualdade de gênero, a participação das mulheres na Assembleia Legislativa do Estado da Bahia - ALBA. Através de uma abordagem empírica fundada no levantamento quantitativo dos mandatos parlamentares exercidos por mulheres em cada legislatura da ALBA após 1988, pretende-se demonstrar como a participação feminina naquela instituição representativa ainda é incipiente e enfrenta uma série de obstáculos. Tal constatação confirma algumas das hipóteses da literatura feminista sobre gênero e política e também da teoria democrática contemporânea sobre a baixa representatividade feminina nos órgãos legislativos. Ao final, apresentam-se indicativos a serem avaliados como alternativas inclusivas enquanto as estruturas partidárias não conseguem promover maior equilíbrio de gênero na representação política. PALAVRAS-CHAVE: Igualdade de gênero; Democracia; Representatividade Política Feminina. ABSTRACTThis paper analyses the female political representation in the Legislative Assembly in the State of Bahia - ALBA, under a perspective of the constitutional guarantee of gender equality. Through an empirical approach stablished in a quantitative research on parliamentary mandates from women in each legislature since 1988 it is intended to show how female participation in that institution is still incipient and faces several obstacles. The evidence confirms some of the hypotheses of feminist literature on gender and politics and also from contemporary democratic theory on low female representation in legislative bodies. In the end, there are suggestions to be evaluated as inclusive alternatives as long as party structures cannot promote greater gender balance in political representation.  KEY WORDS: Gender equality; Democracy; Female Political Representation.

Reflective practices are considered an important part of a pre-service teachers’ (PSTs) professional learning experiences. However, there has been much criticisms on its efficacy as a learning tool for teacher professional development. This paper will relate a study that was designed to compare reflective teaching practices in two culturally different countries, namely Malaysia and Australia. These two countries were chosen as they offered an opportunity to study differences in reflective thinking practices from an Asian and a Western cultural perspective among PSTs. The study used a framework using five constructs: lifelong learning skills, self-assessment, self-belief, teaching awareness, and reflective thinking. The sample consisted of 387 Malaysian PSTs and 378 Australian PSTs who are enrolled in Bachelor level programmes. The results clearly indicate that while reflective thinking is emphasised in the teacher education programmes, the conceptualisation of the process of reflective thinking between the two cohorts of PSTs are very different. Limitations and implications for practice are discussed.
Titrated Oral Misoprostol Solution Compared with Intravenous Oxytocin Infusion for Labour Augmentation
Authors: Shetty Shukla S. , Sneha Sneha , K. Prathusha
Published: May 2021

BACKGROUND The ability to induce and augment labour has been of keen interest to many societies from the time immemorial till date. For majority of the women, the process of labour starts spontaneously at or near term and would result in vaginal “delivery.”1 Augmentation refers to the stimulation of spontaneous contractions that are considered inadequate because of failed cervical dilatation and foetal descent5. The purpose should be to relieve the parturient from the prolonged painful and exhausting delivery process into a short time frame. We wanted to compare the efficacy of titrated oral misoprostol solution with that of IV oxytocin infusion for augmentation of labour and determine the indications for failure of the augmentation process. METHODS The present study is a randomized control trial. 200 patients requiring labour augmentation were divided randomly into two groups by the method of colour code cards that were picked by the patients themselves from November 2011 to October 2013. Titrated oral misoprostol (TOM) solution 20 ml (1 μg / ml, 20 μg total) given for one group every hourly until the contractions were adequate. If adequate contractions were not achieved even after 4 doses, then, the dose was increased to 40 μg till adequate contractions were achieved. Another group received Oxytocin IV infusion with the maximum dosing rate of 20 mill units / min. RESULTS 200 women were enrolled in the study, of whom 100 were given titrated oral misoprostol solution, and 100 were given intravenous oxytocin for labour augmentation. The main outcome of augmentation to delivery interval time was 4 hours in TOM and 4.2 hours in oxytocin group. 88 % and 85 % achieved vaginal delivery within 12 hours in TOM and IV oxytocin group respectively. 8 % and 4 % in the TOM and IV oxytocin group underwent lower segment caesarean section (LSCS) in view of failure to progress, whereas 2 % and 8 % in TOM and oxytocin group had LSCS in view of foetal distress. APGAR score was normal in both the groups. CONCLUSIONS Titrated oral misoprostol solution is as efficacious as IV Oxytocin infusion for labour augmentation. It is safe, inexpensive and easy to use. Augmentation-to-delivery interval is very much reduced with the use of titrated oral misoprostol solution and the incidence of Caesarean section is comparable to that of IV oxytocin group.

Published: May 2021

BACKGROUND One of the major causes of preventable blindness is ocular trauma, which also results in high socioeconomic burden. This study was done to understand the clinical profile of orbital and ocular trauma at a tertiary care centre in Kerala. METHODS A descriptive study was conducted among patients attending the casualty of a tertiary care centre in Kerala for a period of three months from August 2017 to October 2017. A semi structured proforma was filled by the ophthalmologist attending the patients. This data was analysed using appropriate software. The study included a total of 256 patients with orbital and ocular trauma. After taking a detailed history, visual acuity testing and ocular examination were conducted. Computed tomography (CT) scan of orbit was done whenever indicated. RESULTS Out of 256 patients, 60.9 % were in the age group of 21 – 60 years. Males were affected about 4 times more than the females. 40 % of trauma occurred in the afternoon between 12 and 6 pm, and 29 % happened from 6 pm to 12 midnight. Majority of trauma (47.7 %) happened at home followed by those due to road traffic accidents. Conjunctiva and cornea were the most frequently involved ocular structures. Out of 256 patients, 126 (49.2 %) had conjunctival injury while 73 (28.5 %) had corneal injury. Corneal foreign bodies were seen in 32 patients (12.5 %). Only two patients (0.8 %) had open globe injury, whereas others had closed globe injury. Eye lids were injured in 45 patients (17.6 %) and 51 patients (19.9 %) had injury in the periorbital area. Orbital bone injuries were detected in 16 patients (6.3 %) and was confirmed using CT scan. CONCLUSIONS Ocular trauma is an important cause of preventable blindness and ocular morbidity. It causes high economic burden to the individual as well as to the society. Most of the injuries were closed globe injuries and affected the younger population.

BACKGROUND Chronic kidney disease (CKD) is a global health problem which is progressive and asymptomatic until the end stage in recent years which is most common in patients of middle and low socio-economic status. The disease is mostly associated with diabetes or hypertension, young and middle-aged individuals living in agricultural communities and drinking well water. We want to study the clinicopathological profile of chronic kidney disease of unknown aetiology (CKDU) cases admitted in a rural tertiary care hospital. METHODS A retrospective study was conducted among fifty patients who reported with ultrasonography (USG) report showing small shrunken kidneys and / or kidney biopsy suggestive of chronic tubulointerstitial nephritis with absence of immune deposits and admitted in the Medicine department of AVBRH Hospital and JNM College of Medical Sciences, Sawangi (M) Wardha of Central India. RESULTS The mean age was 36.46 ± 10.90 years with majority of the patients between the ages of 35 to 55 years. The body mass index (BMI) of the study group was within 22.52 ± 1.96. CKDU was more commonly seen in males (64 %) as compared to females (36 %). The subjects were predominantly farmers (54 %) who used to drink well water. USG showed small shrunken kidneys in all the study subjects, which was in 100 % cases. Pesticide exposure was seen in 32 % cases. The glomerular filtration rate (GFR) revealed that 30 % of the patients were in grade II. The biochemical report revealed the mean value of haemoglobin to be 8.75 ± 1.39, mean serum urea level to be 64.96 ± 15.19, mean serum creatinine level to be 4.5 ± 2.67, mean serum sodium level to be 132.48 ± 5.83 and mean serum potassium to be 4.43 ± 0.78. The mean random blood sugar (RBS) value was 98.64 ± 19.62, serum calcium level was 8.87 ± 0.43, serum phosphorus level was 5.05±0.39 and urine protein / creatinine ratio was 0.90 ± 0.12. CONCLUSIONS This study highlights the need to review health policies and allocates resources for prevention and treatment of CKDU in Central India, Maharashtra.

Authors: Trivedi Mahendra Kumar , Jana Synthesis
Published: May 2021

Zinc is an essential trace mineral that plays an important role in the human body as a regulator for different enzymatic systems. It is used in various supplements in the form of zinc chloride to meet the daily requirements. This study was designed with the aim to investigate the impact of The Trivedi Effect®- Energy of Consciousness Healing Treatment on the various physical, thermal, and spectral properties of zinc chloride. The study involves dividing the zinc chloride sample in two parts, followed by keeping the first part untreated and named it the control sample. Besides, The Trivedi Effect®- Biofield Energy Healing Treatment was provided to the other part remotely by the renowned Biofield Energy Healer, Mr. Mahendra Kumar Trivedi and the sample was termed as Biofield Energy Treated sample. Later on, both the samples were analyzed using PXRD, PSA, DSC, UV-Vis, and FT-IR analytical techniques. The PXRD analysis revealed the significant changes in the crystallite sizes (from -66.68% to 25.02%) and the relative peak intensities (from -81.35% to 141.22%) along with 26.46% decrease in the average crystallite size of the Biofield Energy Treated sample, compared with the control sample. Additionally, the treated sample showed reduction in the particle sizes d10, d50, d90, and D(4,3) values by 92.18%, 23.24%, 14.48%, and 29.31%, respectively as compared to the control sample. However, the surface area of the treated sample was observed to be significantly increased by 224.57%, compared to the control sample. The DSC analysis revealed slight increase in the melting and decomposition temperature of the Biofield Energy Treated sample by 0.84% and 3.62%, respectively; along with the significant increase in the latent heat of melting and decomposition by 24.85% and 123.23%, respectively, compared to the control sample. It showed that the thermal stability of the treated sample was significantly increased. However, the UV-Vis and FT-IR studies revealed that the structural properties of the control and treated samples were remained same. The overall study represents that The Trivedi Effect®- Energy of Consciousness Healing Treatment may be used to generate a polymorphic form of zinc chloride, which might possess enhanced solubility, dissolution and bioavailability profile along with improved thermal stability, compared to the control sample. Such properties of the treated zinc chloride may ensure its efficacy, stability and safety during the process of shipment, handling, and storage; thus, The Trivedi Effect®-Energy of Consciousness Healing Treated zinc chloride would be useful for designing the better formulation with enhanced bioavailability, stability and efficacy profile.

La ﬂora nativa posee un enorme potencial paisajístico que ha sido poco explorado. En el presente trabajo se han estudiado aspectos relacionados con las semillas y comportamiento germinativo de tres especies vegetales nativas del centro - norte santafesino con potencial ornamental priorizadas para su introducción a la producción en viveros en el marco de las acciones del Programa de Documentación, Conservación y Valoración de la Flora Nativa (PRODOCOVA). Las especies en estudio corresponden a “Sangre drago” Croton urucurana Baill., “Horquetero” Tabernaemontana catharinensis A. DC. y “Ojo de muñeca” Paullinia elegans Cambess. Para C. urucurana se halló una temperatura óptima a temperaturas alternantes de 20-30 °C, mientras que para P. elegans y T. catharinensis, temperatura constante a 25 °C determinó el mayor porcentaje de germinación. Se identiﬁcaron para todas las especies el momento para el recuento inicial y ﬁnal del porcentaje de germinación. Adicionalmente se observó que semillas de P. elegans son recalcitrantes. Estos resultados son de gran utilidad para la introducción a cultivo de las especies en estudio.

Published: May 2021

Trichloris crinita es una gramínea nativa de distribución disyunta que habita regiones áridas y semiáridas de Sud y Norteamérica. Trabajos previos mostraron uniformidad en el nivel de ploidía en poblaciones sudamericanas de la especie (2n = 4x = 40); sin embargo, se desconocen valores de referencia para poblaciones norteamericanas. En el presente trabajo se implementó un protocolo para cuantiﬁcar el contenido de ADN nuclear (indicador de ADN-ploidía) mediante citometría de ﬂujo, y comparar dicho valor en 22 poblaciones provenientes de Sudamérica (15) y Norteamérica (7). No se encontraron diferencias de contenido de ADN nuclear entre poblaciones sudamericanas y norteamericanas (valor 2C promedio = 1,97 pg) y tampoco entre poblaciones dentro de cada uno de dichos subcontinentes, sugiriendo que todas presentan el mismo nivel de ploidía. Estos resultados proporcionan datos de referencia sobre el contenido de ADN nuclear de T. crinita a lo largo de su rango en Sud y Norteamérica.

Prosopis alba posee potencial para la producción forestal y forrajera, destacándose su utilización en zonas áridas y semi-áridas. La especie, considerada de difícil enraizamiento, se propaga comercialmente mediante semillas. Su clonación permitiría cultivar materiales de interés silvícola altamente productivos y en un menor tiempo. El objetivo de este trabajo fue analizar el grado de ligniﬁcación de estacas y miniestacas de P. alba y su relación con su capacidad de enraizamiento. Los brotes obtenidos del jardín y minijardín clonal fueron inducidos al enraizamiento con diferentes concentraciones de IBA. Se realizaron cortes anatómicos de los brotes, previo a la inducción del enraizamiento y 40 días posteriores al mismo para observar la ligniﬁcación de estos materiales y relacionarlos con estacas y miniestacas enraizadas. Las miniestacas con mayor grado de juvenilidad y de etiolación presentaron menor grado de ligniﬁcación y lograron mayores porcentajes de enraizamiento (99,6%) con respecto a las estacas (7,6%). Se observó que la utilización de la técnica de miniestacas asociada a la de etiolación son promisoras para la propagación vegetativa de P. alba y posiblemente de otras especies nativas de difícil enraizamiento.

Published: May 2021

El objetivo general del ensayo fue evaluar el uso de dos métodos de propagación vegetativa en P. chilensis: (A) acodo aéreo y (B) en montículo. En (A) se emplearon árboles de 3,5 años de edad y se ensayaron en dos épocas (primavera-verano), con AIB 1 % y el control testigo. En (B) se usaron plantas de 8 meses de edad, anillado con alambre y diferentes tipos de sustratos: arena, turba y una mezcla de ambos. Se obtuvieron 42,5 % de acodos enraizados en primavera con AIB y un promedio de 14,5 raíces por acodo aéreo, sin diferencias con respecto al verano. En (B), el máximo porcentaje de enraizamiento fue del 75 % en el sustrato arena, con alambre y un promedio de 3,89 raíces por acodo. En (A) se concluye que AIB mejora el porcentaje de enraizamiento en ambas épocas; y en (B) el alambre favorece el enraizamiento de los acodos en montículo en presencia del sustrato arena.

Continuous-flow left ventricular assist device implantation is the typical treatment for end-stage heart failure. Improvements in device engineering and technology, surgical experience and technique, and perioperative management have advanced the field, and short-term results approach those of heart transplantation. Further improvements may be achieved by minimizing adverse physiologic effects associated with cardiopulmonary bypass. Therefore, we have developed an off-pump implantation approach for continuous-flow left ventricular assist devices. We detail our surgical technique for off-pump implantation of the HeartWare device.

This work focuses on the study of the polychrome decoration of the Patio de las Doncellas in the Palace of Pedro I (1356-1366), part of the Real Alcázar de Sevilla ensemble. The decoration of this space has undergone many interventions throughout its history to adapt to the fashions of the time. Therefore, the current surfaces seen nowadays look nothing alike their original appearance. With the aim of identifying the different polychromies and chronologically dating them, an exhaustive research on the plasterwork and wooden decoration (carved-alfarje and not carved-freeze) has been carried out based on documentary research, fieldwork and analytical studies.

Argument parsing via corpus queries
Authors: Dykes Natalie , Evert Stefan , Göttlinger Merlin , Heinrich Philipp , Schröder Lutz
Published: May 2021

We present an approach to extracting arguments from social media, exemplified by a case study on a large corpus of Twitter messages collected under the #Brexit hashtag during the run-up to the referendum in 2016. Our method is based on constructing dedicated corpus queries that capture predefined argumentation patterns following standard Walton-style argumentation schemes. Query matches are transformed directly into logical patterns, i. e. formulae with placeholders in a general form of modal logic. We prioritize precision over recall, exploiting the fact that the sheer size of the corpus still delivers substantial numbers of matches for all patterns, and with the goal of eventually gaining an overview of widely-used arguments and argumentation schemes. We evaluate our approach in terms of recall on a manually annotated gold standard of 1000 randomly selected tweets for three selected high-frequency patterns. We also estimate precision by manual inspection of query matches in the entire corpus. Both evaluations are accompanied by an analysis of inter-annotator agreement between three independent judges.
Hydro-alcoholic extract of Morus nigra reduces fasting blood glucose and HbA1c% in diabetic patients, probably via competitive and allosteric interaction with alpha-glucosidase enzyme; a clinical trial and in silico analysis

Published: May 2021

Objectives

1-Deoxynojirimycin (1-DNJ), the main active component found in Morus nigra (black mulberry) is reported to be effective in controlling diabetes. We have evaluated the effect of hydro-alcoholic extract of M. nigra leaves on the fasting blood glucose (FBS) and hemoglobin A1c% (HbA1c%) in diabetic patients. Furthermore, we compared the interaction of 1-DNJ and glucose molecules with the alpha-glucosidase enzyme, which has a critical role in the lysis of glucose-based polymers in human cells.

Methods

4% hydro-alcoholic extract was prepared from black mulberry leaves. Patients in treatment (n=50) and control (n=50) groups received 3 mL extract or placebo in water, respectively, and three times a day. Fasting blood glucose and HbA1c% were evaluated before and after three months of evaluation. Potential binding sites of 1-DNJ or glucose on the enzyme glucosidase found by docking study. Docking scores were obtained using an energy minimization method by Molegro Virtual Docker software. The Mean ± SD of each variable was compared between groups at the 95% significant level.

Results

Age mean ± SD was equal to 54.79 ± 9.203 (38–69) years. There was no significant difference between intervention and placebo groups considering FBS (p=0.633) but was for HbA1c% (p=0.0011), before treatment. After three months, both FBS and HbA1c% were significantly reduced in patients under mulberry leaves extract-treatment. FBS changed was from 182.23 ± 38.65 to 161.23 ± 22.14 mg/dL in treatment group (p<0.001) and from 178.45 ± 39.46 to 166.23 ± 29.64 mg/dL in control group (p<0.001). HbA1c was changed from 7.23 ± 0.25 to 6.13 ± 0.61% in treatment group (p<0.001) and from 7.65 ± 0.85 to 7.12 ± 0.33% in control group (p=0.854). Docking results showed that 1-DNJ binds more efficiently, and with a significant score than glucose, to human alpha-glucosidase.

Conclusions

This clinical trial and virtual analysis showed that a hydro-alcoholic extract of black mulberry (M. nigra) leaf may be efficient in reducing the blood glucose and HbA1c% in diabetic patients. Furthermore, docking studies propose a competitive and allosteric regulation for herbal ingredients. Drug-development could be based on the presented idea in this report.

Published: May 2021

Multilocation experiments are the steps to determine the genotype stability being tested. Honey sweet potato is a superior agricultural product from West Java, Indonesia. High yield and sweetness are the important traits of the new honey sweet potato breeding lines. In this study, the sweetness level used was the soluble solid level (°brix). The goals of this study were to determine the effects of genotype by environment interactions (GEIs) and to select for storage root yield stability and sweetness among the new promising honey sweet potato lines. Field trials have been carried out using randomized completed block design, which was repeated thrice for the 16 genotypes, across six locations in West Java, Indonesia. To estimate GEIs, data were analyzed using combined analysis of variance. Storage root yield stability (t/ha) and sweetness (°brix) were estimated using parametric measurements, nonparametric measurements, and GGE biplot. The results showed that the genotype (G), environment (E), and GEIs have significant influences on storage root yield and sweetness. Two genotypes, SP3 and SP16, have been identified as the most stable ones with high yield and sweetness across several locations. These two superior genotypes are recommended as potential new honey sweet potato varieties for West Java, Indonesia.

Severe COVID-19 disease is associated with an increase in pro-inflammatory markers, such as IL-1, IL-6, and tumor necrosis alpha, less CD4 interferon-gamma expression, and fewer CD4 and CD8 cells, which increase the susceptibility to bacterial and fungal infections. One such opportunistic fungal infection is mucormycosis. Initially, it was debated whether a person taking immunosuppressants, such as corticosteroids, and monoclonal antibodies will be at higher risk for COVID-19 or whether the immunosuppresive state would cause a more severe COVID-19 disease. However, immunosuppressants are currently continued unless the patients are at greater risk of severe COVID-19 infection or are on high-dose corticosteroids therapy. As understood so far, COVID-19 infection may induce significant and persistent lymphopenia, which in turn increases the risk of opportunistic infections. It is also noted that 85% of the COVID-19 patients’ laboratory findings showed lymphopenia. This means that patients with severe COVID-19 have markedly lower absolute number of T lymphocytes, CD4+T and CD8+ T cells and, since the lymphocytes play a major role in maintaining the immune homeostasis, the patients with COVID-19 are highly susceptible to fungal co-infections. This report is intended to raise awareness of the importance of early detection and treatment of mucormycosis and other fungal diseases, such as candidiasis, SARS-CoV-2-associated pulmonary aspergillosis, pneumocystis pneumonia and cryptococcal disease, in COVID-19 patients, to reduce the risk of mortality.
L’ engagement réussi de l’éducation supérieure en région envers l’intelligence collective
Authors: Proulx Marc-Urbain , Bouchard Pierre-Luc
Published: May 2021

Les institutions de l’éducation supérieure sont universellement sollicitées pour s’engager davantage dans une troisième mission, la fertilisation des innovations, à côté de l’enseignement et de la recherche. Les faits dévoilés dans cet article illustrent que, depuis cinq décennies, cet engagement s’avère déjà considérable pour les universités et les collèges des régions périphériques du Québec. Les programmes d’enseignement traditionnels se sont multipliés, diversifiés et segmentés en ciblant, à plus de 30 %, des besoins spécifiques au sein des milieux desservis. Ces besoins orientent aussi la grande majorité de la recherche appliquée, qui explose depuis quelques décennies. En outre, de nouvelles fonctions sont déjà bien exercées, principalement la formation continue, l’incubation d’entreprises et le transfert de savoir. Après l’effervescence initiale, le nouvel engagement souhaité apparaît déjà en vitesse de croisière. Il demeure néanmoins des potentialités réelles. Le principal défi à cet effet consiste à concevoir de nouveaux outils pour soutenir l’innovation aux régions en pleine transition.
Concurrent Diabetic Ketoacidosis and Acute Pancreatitis in Mild Hypertriglyceridemia: An Enigmatic Triangle
Authors: Cho Eunae , Park Chang Hwan
Published: May 2021

Hypertriglyceridemia (HTG) is a well-established cause of acute pancreatitis (AP). Diabetic ketoacidosis (DKA) leads to lipolysis and HTG, and can result in AP. Triad of AP, DKA, and HTG is rare and not fully understood. Usually AP is associated with severe HTG with serum triglyceride (TG) level over 1,000 mg/dL. However, we experienced two cases of AP in DKA with mild HTG with TG level less than 200 mg/dL. Herein, we report these unusual cases and provide a review of the literature about the triad of DKA, HTG, and AP.
