Published: December 2022

Rice is one of the global most critical harvests, and a great many people eat it as a staple eating routine. Different rice plant diseases harm, spread, and drastically reduce crop yields. In extreme situations, they may result in no grain harvest at all, posing a severe threat to food security. In this paper, to amplify the recognition ability for rice leaf disease (RLD) classification, we proposed hierarchical transfer learning (HTL) methods incorporating ensemble models containing two-step. In the first step, an ensemble combining MobileNet and DenseNet was addressed to tackle the diseased leaf problem. Consequently, DenseNet and XceptionNet were fused to identify three RLDs. Here, we compare our models with state-of-the-art deep learning models such as ResNet, DenseNet, InceptionNet, Xception, MobileNet, and EfficientNet. Our framework at top-notch with 89 % and 91 % for accuracy. In future works, RLD segmentation is suggested to pinpoint the illness and quantify the afflicted region.

Published: December 2022

Acute appendicitis (AA), one of the most common causes of lower abdominal pain, is the most common diagnosis given to young children admitted to the hospital with acute abdominal pain. According to statistics, the lifetime risk for AA was 9% in the USA, 8% in Europe, and 2% in Africa. Over the past 20 years, a rise in interest in the non-operative care of uncomplicated AA care has developed, most likely due to a more accurate analysis of postoperative complications and costs of surgical interventions, which are primarily connected with minimally invasive techniques, which are on the rise. This study aimed to evaluate the current literature on the non-surgical management of AA, thus, studies discussing the non-surgical management of AA between 2009 and 2022 were included. Initially, the non-operative treatment seemed possible to avoid appendectomy, reducing the need for surgery, surgical risks, and overall costs. Antibiotic therapy has a high success rate and is both feasible and effective; the risk of treatment failure is higher than the risk of appendectomy. Although the conservative treatment had a low overall failure rate, individuals who received upfront surgery had a greater complication risk.

Despite fast developments in non-invasive diagnostic techniques, the initial cardiovascular exam still includes the auscultation of heart sounds with a stethoscope. This systematic review aimed mainly to study the developments in chest auscultation using digital stethoscopes and artificial neural network that interprets the results of electronic stethoscopes in detecting and differentiating innocent and pathological murmurs in the pediatric population. PubMed, Web of Science, Science Direct, EBSCO, Scopus, and Cochrane library were searched. Seven studies were included, with 671 patients. Out of the total population, 217 patients had innocent murmurs, and 403 had pathological murmurs. All the included studies reported that digital auscultation could differentiate pathological and innocent murmurs, which is a fast and cost-saving method. It was found that digital auscultation has a diagnostic benefit in identifying pathological and innocent murmurs. Studies also revealed that a quick and affordable strategy could be a big assistance when making decisions.

Soil problems that we often encounter, especially in Indonesia, are soft soils that have low bearing capacity and large displacements. Soil stabilization is needed to improve these parameters, and one way to stabilize the soil is an improvement technique using the Deep Cement Mixing method. In this era, technology is very helpful in daily activities, including for construction. Modeling of buildings, pavements, bridges, and other projects can be done visually using the finite element application. With the development of technology, there is always a more detailed finite elements applications compared to the previous versions, which simplifies modeling. This study aims to determine the accuracy of model simplification in two-dimensional finite element modeling by comparing it to three-dimensional finite element modeling. The output results of the two finite elements used to compare are the displacements value and the safety factor value. The data used for modeling in both finite elements are the same, which is soil improvement data of Deep Cement Mixing at the Coal Power Plant Project in Bangladesh. The project is located on the seafront, so the soil is considered as soft soil. Therefore, deep soil improvement is needed and in this case using Deep Cement Mixing method. Permasalahan tanah yang paling sering kita temui terutama di Indonesia adalah tanah lunak yang memiliki daya dukung rendah dan perpindahan yang besar.

ANALISIS DIAGRAM GAYA DALAM PADA FONDASI TIANG BOR UNTUK MENDAPATKAN HASIL PENULANGAN YANG OPTIMAL
Authors: Rohan Kilian , Prihatiningsih Aniek
Published: December 2022

The foundation is one of the most important parts of a structure. The distribution of bearing capacity in pile foundations is inversely related to depth. The part of the pile that is close to the acting force will carry a greater force than the part of the pile that is at a deeper depth. By paying attention to this, the reinforcement of the pile foundation can be varied according to the distribution of the pile bearing capacity. The type of pile foundation to be analyzed is a drilled pile foundation or bored pile in the form of an end bearing pile, with soil data located in Semarang. Analysis was carried out on three piles with a diameter of 600 mm, 1000 mm, and 1800 mm with a pile length of 65 m. In this study, an analysis of the internal force diagram that occurs in the pile will be carried out. The results of the analysis show that the need for pile reinforcement are getting less and less at the pile which is further away from the working load. The result of the need for pile reinforcement is also less than the reinforcement based on applicable regulations.
 
Abstrak
Fondasi merupakan salah satu bagian terpenting dalam sebuah struktur. Salah satu jenis fondasi yang sering digunakan pada proyek pembangunan gedung dan struktur-struktur besar lainnya merupakan fondasi tiang. Distribusi daya dukung pada fondasi tiang berkebalikan dengan kedalaman. Bagian tiang yang dekat dengan gaya yang bekerja akan memikul gaya yang lebih besar dibandingkan bagian tiang yang berada pada kedalaman yang lebih dalam. Dengan mempehatikan hal tersebut, maka penulangan fondasi tiang daanapat divariasi sesuai dengan distribusi daya dukung tiang. Penelitian ini akan dibantu dengan menggunakan program untuk mendapatkan penulangan tiang. Jenis fondasi tiang yang akan dianalisis merupakan fondasi tiang bor atau bored pile berupa end bearing pile, dengan data tanah yang berlokasi di Semarang. Analisis dilakukan terhadap tiga tiang dengan diameter 600 mm, 1000 mm, dan 1800 mm dengan panjang tiang 65 m. Dalam penelitian ini, akan dilakukannya analisis diagram gaya dalam yang terjadi pada tiang sehingga dapat diketahui nya letak dan kebutuhan tulangan sepanjang tiang. Hasil analisis menunjukkan bahwa hasil kebutuhan penulangan tiang semakin sedikit dan renggang pada bagian tiang yang semakin menjauhi beban yang bekerja. Hasil kebutuhan penulangan tiang juga lebih sedikit dibandingkan penulangan berdasarkan peraturan yang berlaku.

Published: December 2022

Heliciopsis lobata (Merr.) Sleumer is a popular herbal material in the North-West territories of Vietnam. The wood of this plant is still used for the treatment of some liver diseases, although there is no scientific evidence for evaluating these activities and the safety of this herbal material. Our study focused on accessing acute toxicity and hepatoprotective activity of water extract from the wood of Heliciopsis lobata. Among experimental groups of mice induced by high dosage of paracetamol, mice were treated with extract at dosages of 0.56 g/kg, 1.15 g/kg and 2.30 g/kg could be against liver damage with different levels. Water extract at dosages of 0.56 g/kg and 1.15 g/kg could maintain the original situation of livers; significantly reduced the increase of ALT and AST enzymes at levels of about 80% and 87% respectively; significantly reduced 70% the increase of AST, and against most of the peroxidation process in liver tissue. A dosage of 2.30 g/kg expressed lower hepatoprotective activities in comparison with the former dosages and which may increase liver toxicity when used with high dosages of paracetamol. The highest experimental dosage at 32.60 g/kg did not show acute toxicity by independent oral administration. It could be concluded that water extract of the wood of Heliciopsis lobata exposed hepatoprotective ability with dosage from 0.56 g/kg to 1.15 g/kg, equivalent to dosages from 60 g to 120 g for humans per day.

Legal institutional inefficiency and water pollution problem in Bangladesh
Authors: Wang Shuying , Islam Md. Ziaul
Published: December 2022

In recent years the economy of Bangladesh has increased significantly due to rapid industrialization. Despite economic prosperity, it causes serious damage to the environment by polluting water resources. Factors like discharging industrial effluents, urban runoff, and agricultural wastage are primarily responsible for polluting the water bodies in Bangladesh. This kind of pollution not only harms the environment but also severely affects human health, and in Bangladesh, nearly 80 percent of all diseases are related to water pollution, and arsenicosis is one of them. To prevent and control water pollution, the government has primarily enacted various laws and policies, including Environment Conservation Act 1995, Environment Protection Act (EPA) 1995, Environment Court Act 2000, and Bangladesh Water Act 2013. Despite numerous initiatives, legal loopholes, institutional weaknesses and lack of enforcement of Environment Impact Assessment (EIA) are the main obstacles to preventing and controlling water pollution in Bangladesh. Therefore, this paper addresses the legal shortcomings and functions of respective bodies in preventing and controlling water pollution.

Após análise desses fatores, é de grande importância a avaliação precoce e rápida do estado do paciente para que haja apropriado manejo, levando em consideração sua individualidade. Outrossim, é necessário que os profissionais tenham conhecimento sólido sobre as diferentes medidas, que haja eficiente organização da equipe e protocolos estabelecidos nos locais de promoção à saúde. Para isso, a capacitação profissional deve ser implementada e mantida como educação continuada, abordando os diferentes manejos e seus momentos de utilização, valorizando o aprimoramento constante dos métodos sobre esses pacientes, para todos os profissionais da saúde. Somado a isso, deve-se incentivar a notificação dos casos pelos profissionais, afinal, a subnotificação dos casos apresenta-se como um problema para o levantamento de estimativas acerca de agressões decorrentes da agitação psicomotora. Portanto, diretrizes claras e procedimento operacional padrão devem ser incentivados, procurando manter ambientes profissionais seguros a todos.
Computationally Examining the Effect of Plate Thickness on Hole-Emitter-Type Electrospray Thrusters
Authors: Maharaj Sahil , Yunus Malik Mobin , Allegre Olivier , Lucy Smith Katharine
Published: December 2022

A new method for determining the onset voltage of electrospray thrusters is proposed, which specifically focuses on electrospray thrusters manufactured by laser drilling through flat plates. The novelty of this method is that it accounts for the effect of the thickness of the plate on the electrospray onset voltage requirements, while traditional methods do not. Key results from this study indicate that for certain materials a change in thickness results in a notable change in the onset voltage, which implies that the plate thickness needs to be considered when planning the design of the thruster emitters. This methodology allows for a robust method of observing the influence of key parameters on the onset voltage. These developments can potentially facilitate and improve the design of these thrusters, enabling an accurate understanding of the power requirements before manufacture.
Formal Safety Envelopes for Provably Accurate State Classification by Data-Driven Flight Models
Authors: Cruz-Camacho Elkin , Amer Ahmad , Kopsaftopoulos Fotis , Varela Carlos A.
Published: December 2022

Aerospace systems are inherently stochastic and increasingly data-driven, thus hard to formally verify. Data-driven statistical models can be used to estimate the state and classify potentially anomalous conditions of aerospace systems from multiple heterogeneous sensors with high accuracy. In this paper, we consider the problem of precisely bounding the regions in the sensor input space of a stochastic system in which safe state classification can be formally proven. As an archetypal application, we consider a statistical model created to detect aerodynamic stall in a prototype wing retrofitted with piezoelectric sensors and used to generate data in a wind tunnel for different flight states. We formally define safety envelopes as regions parameterized by [Formula: see text] and [Formula: see text], to respectively capture how model-predictable observed sensor values are, and given these values, how likely the model’s accurate state classification is. Safety envelopes are formalized in the Agda proof assistant, used to also generate formally verified runtime monitors for sensor data stream analyses in the Haskell programming language. We further propose a new metric for model classification quality, evaluate it on our wing prototype model, and compare it to the model restricted to two different fixed airspeeds, and enhanced to a continuous Gaussian process regression model. Safety envelopes are an important step in formally verifying precise probabilistic properties of data-driven models used in stochastic aerospace systems and could be used by advanced control algorithms to maintain these systems well within safe operation boundaries.

Published: December 2022

This paper presents Ansys Fluent results for a rectangular exhaust nozzle test case from the Fifth AIAA Propulsion Aerodynamics Workshop. The main objective of the workshop was to assess the aerothermal interaction of a heated air exhaust with a film-cooled plate downstream of a convergent nozzle exit, which is representative of engine exhaust flow applications with film cooling. Two sets of hierarchical computational meshes are employed. The first set of meshes consists of workshop-provided Pointwise® meshes. The second set of meshes is generated using Ansys Fluent meshing. Steady conjugate heat transfer simulations with radiation are performed to account for heat conduction through solid materials as well as the electromagnetic heat produced by the solid surfaces of the plate, plenum, and nozzle. Reynolds-averaged Navier–Stokes simulations using the shear-stress [Formula: see text] turbulence model are conducted for a workshop-defined nozzle condition, set point 42, using three blowing ratios. Computational fluid dynamics results are validated against experimental velocity and temperature measurements recorded above the film-cooled plate.

Published: December 2022

In the present work, an experimental study of the effect of aluminum and boron carbide powder mixture composition on the microstructure and basic properties of the cold sprayed coatings was carried out for the first time. A series of coatings deposited on stainless steel substrates was obtained. The microstructure of the deposited coatings was analyzed by scanning electron microscopy and X-ray diffraction analysis. The microhardness and bonding strength of the coatings were measured. It was shown that an increase from 0 to 72 vol.% in the boron carbide content in the powder mixture leads to an increase in its content from 0 to 15-17 vol.% in the coating, its microhardness – from 46.3 to 72.4 HV0.3, and bonding strength – from 17.4 to 61.4 MPa. The obtained results open up broad prospects for the application of the cold spray method to deposition of functional coatings, which are highly demanded in the nuclear industry.

The Practice of Religious Moderation Based on Theo-anthropocentric in Indonesian Islamic Boarding Schools: A Phenomenological Study
Authors: Umiarso  , Muhammad Qorib
Published: December 2022

Religious moderation was an important value in the life of modern society. The article aimed to anayze the practice and implications of religious moderation in Indonesian Islamic boarding schools based on theo-anthropocentric values. This research was qualitative field research with a phenomenological approach. The source of the research data was Islamic boarding schools in Indonesia and taken by representatives of the regions of East Java and Southeast Sulawesi as one of the largest Islamic boarding schools in Indonesia. The research participants were 30 people including, the leaders of the pesantren, the caretakers of the pesantren, and the students of two major Islamic boarding schools in East Java. Data collection was done by interview technique. The data analyst follows a procedure that begins with data collection, data reduction, data presentation, and conclusion drawing. This result showed three main keys to the practice of religious moderation. First, the practice of moderation was in harmony between technology or theory and its application in the field. Second, the moderation attitude in the pesantren and its environment could prevent the emergence of radicalism. Third, this moderation practice also fosters and forms a tolerant and democratic attitude toward all the differences that exist. The results of this study could serve as a simple guide in applying of diversity moderation in other areas. The existence of limitations on the validity of the data and the depth of analysis was a note that needs to be completed in the future.

Storytelling Techniques and Features of Plot Structure in Web Series
Authors: Prokhorov Artem V.
Published: December 2022

Web series are a modern and actively developing audiovisual format, which, however, has so far received only limited attention from researchers. The format’s specific nature implies that it must be viewed from three angles at once: as an audiovisual product, in many ways akin to television and cinema formats; as a type of Internet content that exists in tune with the laws of its environment; and, finally, as a series per se, created with the canons and rules of serial narration in mind. Building on these three key aspects, it is possible to identify the specific format features of a web series and to find out how they influence its creation process, for example, in terms of storytelling strategies used in web series scriptwriting.

This article examines nine web series of different genres, produced in nine countries around the world. The aim of the study is to discover and trace the relationship between the specific features of web series as a format and the story structure of the selected series. Joseph Campbell’s monomyth scheme serves as a main tool of analysis and allows to present this structure as a series of key stages, making it explicit. As a result, it becomes visible how the hero’s classic journey gets transformed in a web series. This makes it possible to identify the main features of storytelling in this format and the techniques used by screenwriters. These techniques include, in particular, a quick start of the story, a focus on the heroes’ inner journey, complete exclusion of their parents from the plot, and some others. Thus, the study comes to the conclusion that the specificity of web series as a format is not only taken into account by screenwriters, but also forces them to transform the classic plot schemes to a large extent.
Dark Ink in Recipes from Russian Publications of the 18th—19th Centuries
Authors: Vishnyakova Yulia I.
Published: December 2022

The study of records, handwritten notes and images on books allows to reveal the history of book existence as part of the history of society, to consider the reading process as a process of interaction between the reader and the book, and to trace the spread of books among various social groups. One of the “main characters” of this process, without a doubt, is ink — a material without which the creation of notes and drawings on books, and just on paper, would have been impossible. Specialists have a good idea of the appearance of the 18th—19th centuries records made with characteristic brown ink, the quality of which their authors paid great attention to, and often made it themselves. Ink had appeared in the ancient world, and, throughout history, ink recipes have been invented, developed, improved and, most importantly, recorded and published, which allows modern researchers to study them on the basis of preserved practical “manuals” and “home economics”. This study examines in detail the various components that were used to prepare ink in the 18th—19th centuries, describes the process of its production, and provides ink recipes from Russian publications of the 18th—19th centuries. The article shows that the number of recipes was increasing from century to century, which indicates an endless search for a perfect composition. Each manufacturer would develop their own “branded” recipe.

Exploring the scientist’s work in the context of the development of art criticism of the 19th century, the article reveals methodological errors in the attribution and identification of iconographic sources of Russian engraving of the 17th century. The article shows the features of D.A. Rovinsky’s approach to specific works, which determined his conclusions and observations in the assessment of Russian engraving of the 17th century, some of them remain relevant today. There are demonstrated the material research characteristics associated with socio-political reasons that determined the direction of censorship in relation to the study of plots and iconographic issues of early Russian engraving. The article shows for the first time the features of studying early Russian engraving of the 17th century as an independent phenomenon, reveals the origins of the formation of modern trends in art criticism (engraving) research, and demonstrates the processes of formation of our ideas about the initial stage of the development of the art of engraving in Russia as a special kind of art and a phenomenon of artistic culture.
“A Philosopher for Pinkerton” and “An Unfortunate Reactionary” (The Polemic of K.I. Chukovsky and V.V. Rozanov in 1908—1911)
Authors: Lomonosov Aleksey V.
Published: December 2022

The idea of finding the source of V.V. Rozanov’s genius never left K.I. Chukovsky. The article traces the public polemical speeches of the writers from the period of K.I. Chukovsky’s residence in St. Petersburg to the end of the most vivid polemic in 1910—1911. There are examined the hidden details of the polemic of 1908—1909. It was devoted to mass detective literature. The article reveals fundamental differences between the writers. For the first time, there are presented handwritten additions to the well-known polemical article by K.I. Chukovsky “An Open Letter to V.V. Rozanov”. The author reveals the primacy of K.I. Chukovsky’s critical speech among the participants of the polemic with V.V. Rozanov of 1910—1911. The draft versions of V.V. Rozanov’s objections have never been published before as well. A comparison of the contents of K.I. Chukovsky’s letters and critical articles against V.V. Rozanov leads to the conclusion about the complexity of the writers’ relations to each other. They both highly evaluated the literary talent in their political opponent. At the same time, both V.V. Rozanov and K.I. Chukovsky followed the political direction of periodicals. Loyalty to the political programs of literary press bodies was mandatory. The article draws attention to the similarity of the ideas about the eclectic formation of cultural processes in society. V.V. Rozanov and K.I. Chukovsky were guided by the idea that political processes were secondary compared to the moral organization of a person. In the reissue of the “Open Letter”, the critic removed the texts condemning V.V. Rozanov for his opposition to the revolutionary movement.
The Art of Old Artists as a Source of Inspiration in the Bookplates by Konstantin Kalinovich
Authors: Koshkina Olga Yu.
Published: December 2022

Konstantin Yuryevich Kalinovich (b. 1959), an artist and illustrator who demonstrates exclusive techniques and a high degree of detail in the field of printed graphics, is the owner of a large number of international awards, prestigious art prizes and the title of Corresponding Member of the Royal Society of Painter-Printmakers of the United Kingdom (1992). K.Yu. Kalinovich’s professionalism is also convincingly manifested in small forms — in the art of ex-libris. The artist’s formation as an etcher began in the Leningrad period of his studies in the experimental lithographic workshop of the Leningrad Institute of Civil Engineering under the guidance of G.P. Pakharevsky, and then continued at the Faculty of Graphics of the Ivan Fyodorov Ukrainian Polygraphic Institute. The creative heritage of A. Brunovsky and personal acquaintance with the Slovak master had a great influence on the formation of the individual graphic style. The artist’s bookplates, made in etching, are often homages in memory of old masters: the images created by H. Bosch, Pieter Bruegel the Elder, A. Dürer, H. Avercamp, J. Vermeer, and Rembrandt excite and inspire him to visual interpretation. The chosen range of artistic means is miniature, synthesis, printmaking as an independent expression of ex-libris. The technique is etching, less often watercolor, gouache. The type is a plot bookplate with the preserved function of belonging to a private library and the implementation of the customer’s idea. To the depth, picturesqueness and wide tonal range of etching, the artist adds original technical features: a dial from an old clock is selected as an etching board, and details of the clock mechanism are involved in the image base, correcting and warping the format and field of the etching with blind impressions. The plot echoing with the great artists and the meticulous thoroughness of K.Yu. Kalinovich’s technique generate original stories about the joy and pain of being, framed by a high form of appreciation for the art of the past. In the works of Kalinovich, the involvement in the composed metaphysical world, the visual images of which are fantastically realistic, monstrously attractive and historically filled, is clearly accentuated. The homage to the old artists’ art in Kalinovich’s bookplates is his world, forcing the viewers to reach for a magnifying glass so as not to miss a single line, while mastering the knowledge of the world art history.

Background. Esophageal squamous cell papillomas are rare epithelial lesions with malignant potential, diagnosed by upper gastrointestinal endoscopy. Their prevalence is from 0.01% to 0.43%. Objective. Description of rare esophageal squamous papilloma diagnosed during upper gastrointestinal endoscopy. Material and methods. A 38-year-old asymptomatic female patient underwent an upper gastrointestinal endoscopy. A growth described as an "esophageal polyp" was detected. The biopsy was performed and specimens were sent for histopathological study. Results. The final diagnosis of esophageal squamous papilloma was made due to histopathological study. Because of the malignant potential of these lesions, once diagnosed, early treatment is essential to prevent progression to esophageal carcinoma. Conclusions. Esophageal squamous papillomas are increasing in prevalence and have been shown to be potentially malignant. This argues the relevance of the problem and the need for widespread immunizations to control human papillomavirus infection.

Bioresourcability is one of the important features for exploring natural biomaterials for sustained and continuous use in the field of medicine. Hence regeneration of silk proteins for various aspects of biomaterial application demands the extraction of silk proteins from silk filaments without compromising their natural properties. In the present study, sericin was extracted from A. mylitta cocoons by autoclave and alkaline method. The surface morphology and degumming ratio were studied to compare the extraction efficiency. The degumming ratio was found to be 13.3% for alkaline and 12.9% for autoclave process. The secondary structure conformations observed through FTIR revealed a higher percentage of α-helix in regenerated sericin of alkaline method (RSNa) and random coils in regenerated sericin of autoclave method (RSA). Total phenol and flavonoid contents of RSA was 618.33±2.27 mgGAE/10g and 472.31±0.63 mg QE/10g and that of RSNa was 521.57±1.18 mgGAE/10g and 449.74±0.57 mgQE/10g respectively. The IC50 value of antioxidant activity of RSNa was 2.84±0.174 mg/mL and RSA 0.995±0.13 mg/mL. Cytocompatibility assays were found to be higher in RSA than RSNa. Overall, regenerated sericin extracted from both methods revealed bioactive functionalities suitable for biomedical applications with RSA being advantageous over RSNa for its cost-effective, timesaving and chemical free extraction method.

Wild vegetables are recognized for their antioxidants, fibres, other bioactive components and consumed as a rich prebiotic source along with probiotics. Crude prebiotics were isolated from wild vegetables and extracts were treated with digestive enzymes to enrich non-digestible prebiotics. The prebiotics were used to prepare different synbiotic formulations with Lactobacillus plantarum strains, L. bulgaricus and L. lactis whereas inulin served as a positive control. These formulations were evaluated for antioxidant activities viz. lipopolysaccharide-induced cell survival assessment and microbial cell adhesion using the HT-29 cell line. All formulations showed significant antioxidant activity. L. plantarum, L. plantarum (LB-VII) and L. bulgaricus with prebiotic Emblica officinalis showed highest DPPH radical scavenging activity (≈85%). ABTS radical scavenging activity was maximum for L. plantarum (LB-VII) with E. officinalis (57%). L. bulgaricus with E. officinalis showed highest FRAP activity (≈515 μM). Cell survival was restored in presence of prebiotics and maximum was observed in L. plantarum (LB-VII) with E. officinalis (77.8%) and the highest microbial cell adhesion was 76% of L. bulgaricus with E. officinalis. Microscopic cell adhesion assay showed successful adhesion to mucus secreted by HT-29 cells. This study underlines and provides evidence for the usage of wild vegetables as a source of prebiotics.
