Authors: Zhang Tuantuan , Liang Zhongmin , Li Wentao , Wang Jun , Hu Yiming , Li Binquan
Published: May 2023

Abstract. Statistical post-processing techniques are widely used to reduce systematic biases and quantify forecast uncertainty in numerical weather prediction (NWP). In this study, we propose a method to correct the raw daily forecast precipitation by combining large-scale circulation patterns with local spatiotemporal information such as topography and meteorological factors. Particularly, we first use the self-organizing map (SOM) model to classify large-scale circulation patterns for each season, then we build the convolutional neural network (CNN) model to extract spatial information
(e.g., elevation, specific humidity, and mean sea level pressure) and the long short-term memory network (LSTM) model to extract time series (e.g., t, t−1, t−2), and we finally correct local precipitation for each circulation pattern separately. Furthermore, the proposed method (SOM-CNN-LSTM) is compared with other benchmark methods (i.e., CNN, LSTM, and CNN-LSTM) in the Huaihe River basin with a lead time of 15 d from 2007 to 2021. The results show that the proposed SOM-CNN-LSTM post-processing method outperforms other benchmark methods for all lead times and each season with the largest correlation coefficient improvement (32.30 %) and root mean square error reduction (26.58 %). Moreover, the proposed method can effectively capture the westward and northward movement of the western Pacific subtropical high (WPSH), which impacts the basin's summer rain. The results illustrate that incorporating large-scale circulation patterns with local spatiotemporal information is a feasible and effective post-processing method to improve forecasting skills, which would benefit hydrological forecasts and other applications.
Enabling dynamic modelling of coastal flooding by defining storm tide hydrographs
Authors: Dullaart Job C. M. , Muis Sanne , de Moel Hans , Ward Philip J. , Eilander Dirk , Aerts Jeroen C. J. H.
Published: May 2023

Abstract. Coastal flooding is driven by the combination of (high) tide and storm
surge, the latter being caused by strong winds and low pressure in tropical
and extratropical cyclones. The combination of storm surge and the
astronomical tide is defined as the storm tide. To gain an understanding of
the threat posed by coastal flooding and to identify areas that are
especially at risk, now and in the future, it is crucial to accurately model coastal inundation. Most models used to simulate the coastal inundation scale follow a simple planar approach, referred to as bathtub models. The main limitations of this type of models are that they implicitly assume an
infinite flood duration, and they do not capture relevant physical processes.
In this study we develop a method to generate hydrographs called HGRAPHER,
and we provide a global dataset of storm tide hydrographs based on time series
of storm surges and tides derived from the Global Tide and Surge Model
(GTSM) forced with the ERA5 reanalysis wind and pressure fields. These
hydrographs represent the typical shape of an extreme storm tide at a
certain location along the global coastline. We test the sensitivity of the
HGRAPHER method with respect to two main assumptions that determine the
shape of the hydrograph, namely the surge event sampling threshold and
coincidence in the time of the surge and tide maxima. The hydrograph dataset can be used to move away from planar inundation modelling techniques towards dynamic inundation modelling techniques across different spatial scales.
The teleconnection of extreme El Niño–Southern Oscillation (ENSO) events to the tropical North Atlantic in coupled climate models
Authors: Casselman Jake W. , Lübbecke Joke F. , Bayr Tobias , Huo Wenjuan , Wahl Sebastian , Domeisen Daniela I. V.
Published: May 2023

Abstract. El Niño–Southern Oscillation (ENSO) is a major source for teleconnections, including towards the tropical North Atlantic (TNA) region, whereby TNA sea surface temperatures (SSTs) are positively correlated with ENSO in boreal spring following an ENSO event. However, the Pacific–Atlantic connection can be impacted by different ENSO characteristics, such as the amplitude, location, and timing of Pacific SST anomalies (SSTAs). Indeed, the TNA SSTAs may respond nonlinearly to strong and extreme El Niño events. However, observational data for the number of extreme ENSO events remain limited, restricting our ability to investigate the influence of observed extreme ENSO events. To overcome this issue and to further evaluate the nonlinearity of the TNA SSTA response, two coupled climate models are used, namely the Community Earth System Model version 1 – Whole Atmosphere Community Climate Model (CESM-WACCM) and the Flexible Ocean and Climate Infrastructure version 1 (FOCI). In both models the TNA SSTAs respond linearly to ENSO during extreme El Niño events but nonlinearly to extreme La Niña events for CESM-WACCM. We investigate differences by using indices for all major mechanisms that connect ENSO to the TNA and compare them with reanalysis. CESM-WACCM and FOCI overall represent the teleconnection well, including that the tropical and extratropical pathways are similar to observations. Our results also show that a large portion of the nonlinearity during La Niña is explained by the interaction between Pacific SSTAs and the overlying upper-level divergence.
Investigating energy production and wake losses of multi-gigawatt offshore wind farms with atmospheric large-eddy simulation
Authors: Baas Peter , Verzijlbergh Remco , van Dorp Pim , Jonker Harm
Published: May 2023

Abstract. As a consequence of the rapid growth of the globally installed offshore wind energy capacity, the size of individual wind farms is increasing. This poses a challenge to models that predict energy production. For instance, the current generation of wake models has mostly been calibrated on existing wind farms of much smaller size. This work analyzes annual energy production and wake losses for future, multi-gigawatt wind farms with atmospheric large-eddy simulation. To that end, 1 year of actual weather has been simulated for a suite of hypothetical 4 GW offshore wind farm scenarios. The scenarios differ in terms of applied turbine type, installed capacity density, and layout. The results suggest that production numbers increase significantly when the rated power of the individual turbines is larger while keeping the total installed capacity the same. Even for turbine types with similar rated power but slightly different power curves, significant differences in production were found. Although wind speed was identified as the most dominant factor determining the aerodynamic losses, a clear impact of atmospheric stability and boundary layer height has been identified. By analyzing losses of the first-row turbines, the yearly average global-blockage effect is estimated to between 2 and 3 %, but it can reach levels over 10 % for stably stratified conditions and wind speeds around 8 m s−1. Using a high-fidelity modeling technique, the present work provides insights into the performance of future, multi-gigawatt wind farms for a full year of realistic weather conditions.
Performance Evaluation Of Supervised Machine Learning Classifiers For Mapping Natural Language Text To Entity Relationship Models
Authors: Omar Mussa A.
Published: May 2023

Transforming natural language requirements into entities involves a thorough study of natural language text. Sometimes mistakes are made by designers when manually performing this transformation. Often, the process is time-consuming and inaccurate. Hence, multiple research studies have been performed to assist inexperienced designers in mapping a natural language text into entities and reducing the time and error that such a method entails. This work is part of those studies. Human intervention is a significant constraint for prior studies. In this paper, machine learning classifiers are used to eliminate human intervention. The system performs well in predicting entities and has achieved 85%, 75% and 80% for recall, precision and the F-score, respectively. The system also performs well in predicting nouns which do not represent entities and has achieved 68%, 79% and 76% for recall, precision and the F-score, respectively. The performance level of the system is the same as other model generation tools found in the literature. The system is distinguished from these tools in using machine learning classifiers as a technique for establishing entities with no human intervention. Furthermore, the study finds that when distinguishing entities from other nouns, logic-based classifiers, perceptron-based classifiers and SVM classifiers perform better than statistical learning classifiers. The decision tree classifier, neural network classifier and SVM classifier all work well. The decision tree is the better because it can provide a decision tree that defines when a noun is an entity and when it is not based on given features; this is not the case with the neural network classifier and SVM classifier.

Published: May 2023

Concentrated solar power (CSP) is viewed as one of the most promising alternatives in the field of solar energy utilization; parabolic trough collector (PTC) solar power plants are the most commercially established among the power plants operating with CSP technology. In this paper, a parabolic trough solar thermal power plant with thermal energy storage was evaluated in terms of design and thermal performance, using the SAM program of NREL (System Advisor Model). This program is used to evaluate the active and economic performance of a plant such as monthly energy production, annual energy production, and level cost of energy (LCOE).one representative site in south Libya, Sebha city, which offers an annual average direct normal radiation (DNI) of more than 6.0 kWh/m2/day, has been chosen for the analysis and optimization of the proposed 100 MWe PTC Solar power plant. The optimization is carried out with solar multiple (SM) and full load hours of thermal energy storage TES as the parameters, to minimize the Levelized cost of electricity and maximize the annual energy yield. Based on the findings of the study, the proposed 100 MW PTC solar power plant with thermal energy storage can contribute to the sustainable energy future of Libya with reduced dependency on fossil fuels. This design and performance analysis of the plant encourages further development and innovation of solar thermal power plants in all regions of Libya.

The purpose of the work is to develop a computer model of ladle heating with an open torch on a drying and high-temperature heating installation to control the thermal preparation process. The task of managing ladle drying and high-temperature heating installations (USVR) is to implement their operating modes, which ensure obtaining the specified temperature profile of the lining layers of steel castings with minimal fuel consumption. The task of controlling by drying and high-temperature heating unit (SHHS) is to implement their operating modes that provide a given temperature profile of steel pouring ladle lining layers with minimal fuel consumption. Since modern technical means of control do not allow obtaining relevant information about the temperature field of the lining of the walls and bottom of the ladle, it is necessary to create a predictive model of its heating by an open torch at the SHHS. A 68-ton rammed steel-pouring ladle KС-68 was chosen as the object of study. According to the research data, the shape and dimensions of the open torch were evaluated at OCC PrJSC “Evraz- Dnipro Metallurgical Plant”. A digital camera recorded the torch at the burner outlet at a natural gas flow rate of 50 m3/h, which corresponds to the standard mode of drying and warming up the ladle. For modeling purposes, the resulting torch shape was approximated by two truncated cones. Determination of the parameters of convective-radiant heat transfer in the “torch – cover – wall – ladle bottom” system was carried out taking into account the temperature of the torch, the thermophysical properties of the lining materials, as well as the irradiance coefficients and the emissivity of the surfaces. The calculation of the temperature field in the lining of the wall and bottom of the ladle was carried out by the finite element method implemented in the ANSYS package. Based on the simulation, a change in the temperature field of the ladle lining was obtained during its heating at the SHHS with an open torch for 6 hours, which corresponds to the current technology. An analysis of the dynamics of the temperature field of the ladle lining obtained as a result of modeling indicates that when it is heated by an open torch at a drying and high-temperature heating unit, thermal stresses do not occur, which are dangerous from the point of view of cracking in the layers of refractory materials. The maximum temperature gradient in the wall is 10 °С/mm, and at the bottom – 6 °С/mm. It has been established that the working surface of the lining warms up sufficiently to avoid thermal shock when steel is poured into the ladle. The results of the research can be useful for optimizing the process of thermal preparing steel pouring ladles.

Introduction: Piper betle Linn is one of the most commonly used compounding plants for ethno-medical purposes, with its extract generally used in modern products to enrich their functional efficacy. The extraction methods always lead to differences in the antimicrobial efficacy of methanol extracts of bioactive compounds. Purpose: The study was conducted to screen for bioactive compounds and determine their antimicrobial efficacy in a methanol extract of Piper betle and Murraya koenigi leaves from five different regions. Methodology: The phytochemical screening done according to the procedure that is implied in from Patil, et.al, with minor modifications by the researchers of the current study. Antimicrobial activity was determined; efficacy was measured by disc diffusion analysis. Results: Phytochemical screening revealed the presence of saponin, tannin, terpenoids, alkaloids and flavonoids in the extracts. The methanolic extract of betel leaves from all the selected regions except from Bau exhibited antimicrobial activities. Among them, extract from Kuching and Simunjan have no effect on E. coli. The methanolic extract of curry leaves from Kuching, Balai ringai and Bau have antimicrobial activities against Staph aureus and those from Balai ringai is also active against E.coli. Conclusion: Although there were previous reports of phytochemical screening and antimicrobial activities from the extract of these plants, there were still lack of research conducted on the specimens especially from our local community (Sarawak). The outcome of this study will help us to identify the bioactive compounds of the local samples and give us some pictures of their activities on how to ensure these plants can be brought forward based on the origin of the sample.

Published: May 2023

Valsartan is an orally active antihypertensive agent which belongs to the category of angiotensin II type I receptor antagonists. Valsartan is used for the treatment of heart failure, hypertension, myocardial infraction and diabetic nephropathy. A new stability indicating RP-HPLC was proposed for the quantification of Valsartan by using an ion-pairing agent, tetra butyl ammonium hydrogen sulphate. Mobile phase mixture consisting of 10 mM tetra butyl ammonium hydrogen sulphate and methanol (25: 75, v/v) was selected with a flow rate of 1 ml/min using Agilent C18 column (Detection wavelength 250 nm). The LOD and LOQ were found to be 0.0291 μg/mL and 0.0897 μg/mL respectively. Linearity was observed over the concentration 0.1-50 μg/mL with linear regression equation, y = 36571x + 13532 and the method is precise, accurate and robust. Stress degradation studies were performed and the method was found to be selective and specific.

Colorectal cancer patients have been experiencing various side effects related to the therapies, both physically and physiologically. Complementary medicine was used to help patients alleviate complaints and increase their quality of life. This systematic review aimed to sort out complementary medicines that could be advised to be used for colorectal cancer patients. Search limitations include the population of colorectal cancer patients, published between 2015 and 2021 and written in English. We found that traditional Chinese medicine, aromatherapy massage, acupuncture, and mindfulness-based stress reduction tests were beneficial in improving patients’ physical and physiological complaints. However, dosing and herb-herb interactions in Chinese traditional medicine and the beneficial persistency effect of other modalities needed further investigation, especially in colorectal cancer patient therapy. Complementary modalities are generally safe; however, some therapies still warrant further investigation to confirm safety and beneficial consistency.
Harmful Effects of Different Classes of Heavy Metals in Our Beautiful Environment
Authors: Saha Avishek , Roy Sanjay
Published: May 2023

Today we all take care very much about environment because it degrades day by day for several reasons; one of them is the accumulation of heavy metals which are one of the intrinsic components of this environment. The excessive accumulation of heavy metals affects all sides’ viz. air, soil, water of our beautiful environment through their adverse impacts. There are too many sources open till now for helping them to enter into the environment. This paper shows how they enter together and affects food chain, plant growth, seed germination, photosynthesis and so many. Excess accumulation of both types of heavy metals viz. essential (Zn, Cu, Fe etc) and non-essential (Pb, Hg, As etc) are responsible for disturbance of both aquatic as well as non-aquatic environment parallelly. Human beings also face slow but steady affect either direct or indirect way. So, we try to reflect how toxic level of heavy metals contamination poses a serious threat to our living environment.
Plant-based Isoquinoline Alkaloids: A Chemical and Pharmacological Profile of Some Important Leads
Authors: Singh Arjun
Published: May 2023

Plant-based products are a one-of-a-kind source of favoured molecules with a wide scaffold variety and broad multi-target potential for the treatment of complicated disorders. Among multi-target NPs, alkaloids have showed anti-inflammatory, anticancer, cardioprotective, and neuroprotective effects, supporting their promise in the treatment of chronic multifactorial disorders. Several recent investigations have revealed that isoquinoline alkaloids (IAs) have multimodal potential, sparking growing interest in the polypharmacological research of these small molecules, particularly in the field of neurological illnesses and cancer. IAs are a broad and diversified category of nitrogenous compounds that are extensively dispersed in living organisms, mostly in plants family. Isoquinolines are known as highly conserved metabolites in early vascular plants at the chemotaxonomic level; moreover, biochemical and molecular phylogenetic investigations have revealed that these alkaloids play an evolutionarily monophyletic role in basal angiosperms.As a result, medicinal chemistry has been experimenting with various ways in order to overcome the constraints of existing paradigms and increase the effectiveness of novel therapeutic molecules. In this context, the search or design of multi-target medications has shown an accelerated breakthrough; in fact, this strategy has sparked the interest of both the scientific community and the pharmaceutical business, allowing several multimodal agents already on the market to be positioned.

A crítica do liberalismo conservador em José Guilherme Merquior.
Authors: Paschoeto Cassimiro Paulo Henrique , Felipe Kaio
Published: May 2023

Este artigo explora alguns elementos da interpretação do liberalismo e do conservadorismo na obra de José Guilherme Merquior, tendo em vista dois problemas fundamentais. Em um primeiro momento, buscaremos tornar explícitos alguns elementos de O Liberalismo: Antigo e Moderno para entender como a contribuição de Merquior traz uma sofisticação teórica e crítica que não estava disponível na nossa literatura sobre história das ideias no período. Num segundo momento, procuraremos demonstrar que sua abordagem crítica permite a Merquior tratar o estudo do liberalismo de modo diverso, compreendendo que é impossível afirmar a existência de uma “tradição liberal” unívoca e que a diversidade de manifestações ideológicas do liberalismo obedece a influxos e conjunções de ideias que responderiam por sua pluralidade. O principal exemplo disso, como pretendemos deixar claro, é o modo como Merquior trata a “variante liberista” do liberalismo como uma conjunção entre ideias liberais e conservadoras, apontando para os limites desse "híbrido" com relação às promessas liberais clássicas.
Orwell à brasileira
Authors: Szwako José Eduardo , Cardoso-da-Silva Matheus
Published: May 2023

O texto apresenta a apropriação feita pela extrema-direita brasileira ao redor da obra de George Orweel, em especial, de '1984' e 'Animal Farm'. Argumentamos que a adjudicação 'conservadora' é inadequada para tal apropriação. Os intelectuais e editoriais implicados na circulação atual de Orwell nas redes bolsonaristas permite ver como clássicos do pensamento conservador ocidental são aqui canonizados em chave, mais que conservadora, reacionária. Além disso, o duelo de distopias empunhados pelos ideólogos da extrema-direita dá também acesso a uma indústria cultural, na qual um sem-fim de produtos culturais são vendidos para forjar e cativar uma plateia potencial reacionária.
Uma obra entre o reacionarismo e o conservadorismo: o pensamento de Olavo de Carvalho
Authors: Chaloub Jorge
Published: May 2023

O presente texto pretende contribuir para o debate sobre a atualidade do pensamento conservador e suas expressões no Brasil a partir da análise da obra do mais influente intelectual da ultradireita brasileira na última década: Olavo de Carvalho. A escolha do autor se deve a sua particular relação com o conservadorismo. Ao mesmo tempo que cultiva ideias mais afinadas com o reacionarismo, distantes das versões mais correntes da tradição conservadora moderna e brasileira, Carvalho é fortemente influenciado pelo conservadorismo norte-americano e construiu sua obra em meio ao convívio com intelectuais como Antonio Paim e Paulo Mercadante, lideranças de perfil semelhante no Brasil. Olavo de Carvalho surge, portanto, como um caminho para refletir sobre os limites e características do conservadorismo, do reacionarismo e da própria ultradireita brasileira.
Descolonizar os Indesconstruíveis: espectrologia, fideísmo e messianidade em Jacques Derrida
Authors: Pinto Neto Moysés
Published: May 2023

O texto investiga os “indesconstruíveis” na filosofia de Jacques Derrida e sua relação com espectrologia, fé e messianidade. Partindo de uma imagem de ziguezague, ela própria presente em diversos ensaios derridianos, aproxima e desaproxima os indesconstruíveis (justiça, perdão, promessa, dom etc.) das ideias de indecidível e decisão, místico e espectral e, finalmente, imanente e transcendente. A partir do debate sobre a Era Axial, pergunta-se, então, se os indesconstruíveis derridianos podem mesmo postular a universalidade, apresentando como contraponto o tratamento da fé secular em Hägglund e da espectralidade nas metafísicas ameríndias tal como descritas por Eduardo Viveiros de Castro.
Contato Improvisação e o corpo como “coisa que sente”: sugestões para outros modos de mobilidade e subjetivação no interior da cultura empreendedora
Authors: Castro Daniele Pires de
Published: May 2023

A partir da crítica a um modelo de mobilidade, próprio ao modo de vida nas sociedades capitalistas contemporâneas, baseado na ideia de avanço contínuo, autoengendrado e objetivamente orientado, propomos a reflexão a respeito de uma forma alternativa de expressão do movimento e, consequentemente, de construção de subjetividades. Através da análise da técnica de dança Contato Improvisação, buscamos identificar e analisar os elementos que contribuem para a experiência concreta de uma mobilidade sem metas, que também leva a outra maneira de nos entendermos como sujeito e nos relacionarmos com o mundo e as coisas a nossa volta. O improviso nos coloca diante de uma mobilidade sem orientação, que abre espaço para a imprevisibilidade. Já o contato nos estimula a mobilizar uma relação com o mundo que enfatiza a aproximação e vulnerabilidade no lugar do distanciamento e da autonomia individual.

Background: Image stitching is the procedure of combining two or more pictures having the same feature point location information into a panoramic image, which is useful in target discovery, seabed research, and military applications. Most of existing underwater picture stitching technology makes use of well-lit photos, however natural light gradually diminishes during propagation of underwater autonomous submersibles plunge further into the sea. When the image focuses on the regions of lighting concentration and the larger dark, image details are lost and feature points are not matched, the perspective transformation matrix obtained does not reflect the mapping relationship of the entire image, resulting in a poor stitching effect and making it difficult to meet practical application requirements. Objective: This study aims to obtain underwater images with a good enhancement effect and improve feature point matching image. Methods: An adaptive image enhancement method based on adaptive light source optimization is proposed in this paper, underwater photos are preprocessed to enhance images for the feature registration. Results: The experimental consequence indicate that the improvement algorithm can improve picture standard with better detail performance and color recovery by preprocessing submerged photographs. Conclusion: It is accomplished that high exactness for images stitching by adding the feature points of the enhanced image for feature alignment.

Design/methodology/approach – 150 samples can be collected from Small and Medium-sized (SEMs) Family Enterprises in China by utilizing the convenience sampling method. And analyzing method in this study, the quantitative method can be selected by adopting IBMSPASS and PLS-SEM. Findings – Both E-HRM (β=0.380, p<0.01) and EP (β=0.545, p<0.01) have a significant positive impact on Job Satisfaction (JS). Job Satisfaction (JS) is an important factor affecting Organizational Commitment (OC). Job Satisfaction (JS) was included in the proposed model as an intermediary variable. Research limitations/implications – the moderating role of JS in the relationship between IVs (E - HRM, EP) and OC was studied using quantitative methods. The research background and research data are limited to small and medium-sized family enterprises and employees in China. Originality/value – By studying the relationship between IVs (E - HRM and EP), MV (JS), and OC, this paper will help to better understand how different E - HRM and EP affect JS, and how JS affects employees For corporate OC's. With the increasing market competition and rising labor costs in China, improving employees' OC for enterprises may be an important means to cope with future competition.
Understanding the Effect of Osteoarthritis on Surgical Treatment Patterns, Healthcare Resource Utilization, and Costs Among Patients With Tenosynovial Giant Cell Tumors
Authors: Lin Feng , Wilson Kathleen , Kwong Winghan J. , Abraham John A.
Published: May 2023

Background:

Tenosynovial giant cell tumor (TGCT) may be misdiagnosed as osteoarthritis (OA), or the chronic course of TGCT may lead to development of secondary OA. However, little is known about the effect of comorbid OA on long-term surgical patterns and costs among TGCT patients.

Methods:

This cohort study used claims data from the Merative MarketScan Research Databases. The study included adults diagnosed with TGCT from January 1, 2014, to June 30, 2019, who have at least 3 years of continuous enrollment before and after the first TGCT diagnosis (date of the first TGCT diagnosis = index date) and no other cancer diagnosis during the study period. Patients were stratified by the presence of an OA diagnosis relative to the index date. Outcomes included surgical procedure patterns, healthcare resource utilization, and costs in the 3-year pre- and postindex periods. Multivariable models were used to assess the effect of OA on the study outcomes, controlling for baseline characteristics.

Results:

The study included 2856 TGCT patients: 1153 (40%) had no OA before or after index (OA[−/−]), 207 (7%) had OA before index but not after (OA[+/−]), 644 (23%) had OA after index but not before (OA[−/+]), and 852 (30%) had OA before and after index (OA[+/+]). The mean age was 51.6 years, and 61.7% were female. During the postperiod, joint surgery was more common among OA(−/+) and OA(+/+) patients compared with OA(−/−) and OA(+/−) patients (55.7% vs 33.2%). The mean all-cause total costs in the 3-year postperiod were $19,476 per patient per year. Compared with OA(−/−) patients, OA(−/+) and OA(+/+) patients had a higher risk of undergoing recurrent surgery and higher total healthcare costs postindex.

Discussion:

Higher rates of surgery and increased healthcare cost observed in TGCT patients with postindex OA underscore the need for effective treatment options to reduce joint damage, especially among patients with comorbid OA.

Active observers can benefit vicariously from the experience of hands-on learners in simulation. Kolb’s experiential learning cycle and vicarious learning theory form the theoretical basis for directed observation during simulation teaching, although little is known about the impact of different simulation technologies on the observer experience.

This mixed-methods crossover study compared student experiences as observers using a high-fidelity manikin and immersive virtual reality (VR) software. Forty-nine final-year medical students were divided into two groups, undertaking and observing scenarios using either the manikin or VR before switching to the other form of simulation.

Forty-eight questionnaires comprising Likert items were completed and analysed, with 11 students participating in focus groups. As observers, the students reported similar experiences with regards to engagement and reflection, with no statistically significant difference between the two technologies. However, the manikin scored higher in domains such as realism, enjoyment, clinical reasoning, usefulness and improved confidence. Students found that ‘participating’ is a more useful experience than ‘observing’ in both technologies. Thematic analysis revealed themes such as skills development, learning experience and technology.

Students valued observing their colleagues completing scenarios within both technologies, highlighting the benefits of observation in focus groups. The high-fidelity manikin scored higher for several domains; however, there was no difference between VR and high-fidelity simulation on perceived observation experience regarding engagement and self-reflection. This suggests VR may have a useful role in observational learning, without the need for a simulation suite.

Published: May 2023

Cancer, one of the deadliest challenges spreading drastically in the 21st century, has now officially become the most dangerous killer in the world according to the World Health Organization. In this current study, we are presenting a case of a 57-year-old female patient who underwent ERCP with biliary stenting to relieve obstructive jaundice. The patient was suspected of carcinoma so during the ERCP (Endoscopic retrograde cholangiopancreatography) procedure a periampullary tissue specimen was taken for biopsy. Biopsy reports revealed periampullary Adenocarcinoma. After that patient refused to opt for chemotherapy and approached KLE Ayurveda Hospital, Belgaum for further management. Immediately, she started with Ayurveda oral medications based on the disease and symptoms on successive follow-ups for almost 9 months. We observed significant clinical improvement along with the normal impression of the computed tomography (CT) of the abdomen which was repeated 2 times with a gap of 3 months during the course of treatment. As well as her alpha-fetoprotein and liver function test (LFT) were within normal limits after the treatment.
