Authors: Ramadhani Ghvirly , Haneda Noor Farikhah , Hilwan Iwan
Published: September 2022

Ficus hispida and Ficus racemosa are Moraceae species that commonly grow on riverbanks. Actions to propagate generative plants required more observation due to mutualistic symbiosis between F. hispida and F. racemosa with Ceratosolen solmsi and Ceratosolen fusciceps as pollinating insects. This study aimed to obtain data on seed production, germination, and the interaction of F. hispida and F. racemosa with pollinating insects. Research activities included seed extraction, seed germination testing, and calculation of the number of pollinating insects found in syconia. The results showed that the number of entered insects was related to syconia's receptive phase and diameter. F. hispida produced 3679 seedlings, while F. racemosa produced 2086 seedlings in one period. The number of seeds could cover a 6 ha area with a 4 m x 4 m spacing of planting. The germination percentage of F. hispida and F. racemosa was low to moderate. F. hispida seed germination was only 57.2% and F. racemosa was 68.6%. Thus, the seed should be germinated immediately after extraction.

Authors: Distrik I Wayan , Setiawan Wawan , Ertikanto Chandra
Published: September 2022

This research aimed to build physics concept understanding and to problem-solve in online learning through the concept attainment learning model. This research employed a quasi-experimental method with a non-equivalent control group pretest-posttest design. The population was natural sciences students in grade XI of Public Islamic School 1 in Pringsewu, Lampung, Indonesia. The samples consisted of 35 grade XI students from class IPA 3 for the experimental group and 34 grade XI students from class IPA 2 for the control group. The concept understanding test consisted of ten problems referring to Anderson and Krotwall’s indicators. The problem-solving test consisted of five problems referring to problems developed by Savage and William. The test results of physics concept understanding and problem-solving ability were analyzed descriptively by grouping the data, calculating the n-gain, and interpreting the data. The difference in physics concept understanding and problem-solving between experimental and control classes were analyzed using an independent sample t-test. The result showed that the n-gains of physics concept understanding and problem-solving ability were in the high and moderate categories, respectively, for the experimental class and the moderate and moderate categories, respectively, for the control class. The independent sample t-test showed that conceptual understanding and problem-solving ability differed significantly between the experiment and control classrooms. This result indicated that the concept attainment model in online learning was better for building physics concept understanding and problem-solving ability for senior high school students than other conventional learning models.
Menerima Instagram Apa Adanya: Melacak Pemaknaan dan Fantasi Individu Pelaku Aktivitas Kerja Sebagai Admin terhadap Aplikasi Media Sosial Instagram
Authors: Sinelir Hanz
Published: September 2022

After the birth of the internet, the relationship between humans and technology is often discussed academically in two poles, namely utopia and dystopia. This study uses examples from the popular social network platform Instagram to find out how users interpret their relationship with technology. The subjects in the study were Instagram account admins, either from commercial brands or social movements. The job of an "Instagram admin" is a new job that requires media literate subjects, who are expected to be able to provide insights on the tug-of-war debate about the relationship with technology. This study uses the concept of fantasy, which is closely related to the formation of the subject in Lacanian psychoanalysis, and is also based on the concept of virtuality by Pierre Lévy. The method used in this study is new ethnography combined with clinical psychoanalysis. The main argument of this research is that Instagram works in the subconscious of its users to cover up castration. This is shown when Instagram (and activities on it) presents language in the form of features and algorithms that exhibit dislocation, continuity, experimentation, and affirmation. Under this condition, what transpires is a sado-masochistic interactivity owing to the failure to recognize the space and rules provided by Instagram. This situation causes anxiety, which in turn generates for the users a relation to fantasy ($◊a). For the admins of Instagram accounts, the process is undergone during their work. By having a fantasy ($◊a), admins gain the possibility to interpret Instagram according to what they desire in life.

Dénouement: A Subjective Reflection on Death, Loss and Grief through Animation Practice
Authors: Ung Lesley
Published: September 2022

Death, a universal human experience, has been represented and understood in numerous ways throughout time and across cultures. Dénouement is a practice-based research project that engages with the emotionally fraught and complex experience of losing a loved one. The research positions the medium of hand-drawn animation as rich territory for exploring visual expressions of the internal, psychological, and abstract dialogue when grieving. As a personal reflection of in-articulable feelings, the aim is not to show the world as it is but as it is travelled through psychologically.
The final short film underpins the practitioner’s passion for drawing the world (as they see it), moving it in time and moving those who view the work, emotionally.

Repensar los momentos, tipos y criterios de evaluación en la Universidad en el marco de nuevos contextos educativos
Authors: Sosa Alexis Alberto , Mancini Veronica
Published: September 2022

En los últimos años la Educación Superior muestra indicios de cambio, referidos al modo de entender la enseñanza y el aprendizaje en la universidad. Se sabe que la enseñanza tradicional está centrada principalmente en la transmisión de conocimientos tomado como “verdades absolutas” y en la verificación de aprendizajes. Las innovaciones han introducido nuevas formas de evaluación, mediante la transformación de su concepción, de sus finalidades y funciones. Hay una variada propuesta para clasificar la evaluación en el proceso de enseñanza/aprendizaje, la cual se conoce desde hace tiempo en el discurso docente. El siguiente trabajo se enfoca en una descripción de la evaluación y sus momentos en el ámbito universitario orientada a mejorar el aprendizaje de los estudiantes; al mismo tiempo se expondrán algunas ideas que fueron analizadas y reflexionadas en el contexto de virtualidad para mejorar las instancias de evaluación en la Cátedra de Procesos Químicos en el 5º año de la Licenciatura en Química de la Facultad de Ciencias Exactas (UNLP). Los cambios de escenarios en el ciclo 2020-21 exigieron un despliegue de estrategias por parte de los docentes en ejercicio que debieron reflexionar a partir de su formación docente para tomar decisiones sobre los momentos y tipos de evaluación, entre otros temas.

Concluimos que la reflexión sobre las propias prácticas de evaluación es un camino posible para mejorarla y ganar coherencia entre el decir y el hacer docente e incluye una deliberación sobre qué “desafíos proponemos cuando evaluamos”.

En este artículo se propone una reflexión sobre la posibilidad de construir una educación no sexista, inicialmente recorriendo hechos claves de la historia  general de la relación entre las mujeres y la formación universitaria, y retomando varios lineamientos teóricos pertinentes, para finalmente describir algunos mecanismos de exclusión que atentan contra la trayectoria académica y profesional de las mujeres. El propósito de esta reflexión es analizar el movimiento académico críticamente e histórico-socialmente contextualizado en términos del sexismo en la educación superior. Un análisis profundo respecto a las relaciones causales de situación requiere de un marco analítico mayor que inspeccione los múltiples modos en que las mujeres han sido excluidas y discriminadas en las universidades considerando que dentro de estas discriminaciones hay categorías epistémicas relacionadas con la formación de un cannon androcéntricamente legitimado. Como por otro lado, parte del análisis recae en percibir cómo se expresa el orden de género en la estructura educativa, condicionando como consecuencia el habitar diario de todes les miembres de la comunidad.

Published: September 2022

This study aimed to verify whether the inclusion of 0.5 kg full-fat rice bran per day in the diet of geriatric horses will improve their condition, increase the population of methanogens in the cecum, and thus affect the biochemical blood parameters. The experiment included 2 research periods: 6 healthy, non-working horses over 20 years of age (480 ± 20 kg of body weight) fed only hay (±8.86 kg/day/head) in the first period and hay (±8.00 kg/day/head) and rice bran (0.5 kg/day/head) in the second one. Each of these periods lasted 4 months. The Body Condition Scoring (BCS) assessment was performed at the beginning and end of the experiment. Blood and feces samples were collected on the first and last day of each period. After feeding with the addition of rice bran, BCS increased by 1.17 units on a 9-point scale. The experiment showed an increase in the total number of bacteria and methanogens inhabiting the cecum of horses. This can lead to better digestion of carbohydrates, absorption of nutrients, and, consequently, increased body weight. No differences occurred in the hematology and serum biochemistry indices of horses fed a diet including rice bran, except for the amount of serum globulin and the albumin to globulin ratio. Rice bran affected essential serum fatty acid profile (increased PUFA and decreased MUFA), which confirmed the possibility to use diet as a serum fatty acids profile modulator.

Published: September 2022

The study determined the effect of introducing 50% of protein from the protein feed pool derived from raw chickpea seeds (CPR) instead of 50% of soybean meal (SBM) in the rearing period from day 22 to 42 on the coefficients of nutrient digestibility, growth performance, selected carcass traits, the hematological and metabolic profile of blood, and the quality of femur bones in male Ross 308 broilers. The study was carried out on 200 22-day-old male Ross 308 broiler chicks (initial weight of 756 g) randomly assigned to two groups (n=100 in each group; 5 cages with 20 birds each). All birds were reared for 42 days. They were fed isonitrogenous and isoenergetic pre-experimental starter diet (day 1 to 21) in crumble form and experimental grower-finisher diets (day 22 to 42) in pelleted form. From rearing day 22, SBM male broilers (grower/finisher) were fed diets with 100% SBM as a protein source. In the diet for the CPR group (grower and finisher), the SBM protein was replaced with 50% of CPR-derived protein. During the grower and finisher stage and between days 22 and 42, the CPR group exhibited significant (P=0.032) reductions in feed intake (FI), higher (P=0.043) slaughter yields, high (P=0.044) % share of breast muscles, and reduced (P=0.003) abdominal fat content. The addition of CPR influenced some blood parameters. The level of total protein, urea, and Mg decreased, whereas the activity of alkaline phosphatase (ALP) and aspartate transaminase (ALT ) increased. In the CPR group, an increase in the physical, morphometric, and some strength parameters of the femur (maximum elastic strength – Wy, yielding deformation – dy, bone density index – BDI, and Young’s modulus) was observed. Therefore, CPR may be a promising partial substitute of SBM in broiler nutrition, as it enhances production performance and has a beneficial effect on bone quality.

Published: September 2022

It has been illustrated that using mixtures of feed additives is more efficient than using individual additives in aquaculture. Hence, this study aimed to study a dietary mixture of betaine, lactic acid bacteria, and exogenous digestive enzymes (BLE) on the growth performance, digestion capacity, intestinal health, and blood indices of Nile tilapia reared outdoors in concrete tanks. Five diets were prepared where the basal diets were mixed with BLE at 0, 0.25, 0.5, 0.75, and 1%. After 90 days, the growth performance of Nile tilapia fed BLE was markedly enhanced in fish fed 0.25 and 0.5% of BLE, while the feed conversion ratio (FCR) was reduced (P<0.05). The lipase activity was significantly higher in tilapia fed BLE at 0.25, 0.5, and 0.75% than 0 and 1%. The amylase activity was meaningfully increased by 0.5% of BLE than 0, 0.25, 0.75, and 1%. The protease activity was significantly higher in tilapia fed BLE at 0.25 and 0.5 than 0, 0.75, and 1% (P<0.05). The intestine of fish fed on BLE showed an increase in intestinal villi density. The villi length, width, and the number of goblet cells were markedly higher in the anterior, middle, and posterior segments of the intestines of tilapia fed BLE than in the control group (P<0.05). Further, fish fed BLE had higher intestinal morphometry indices and count of goblet cells than the control. Significantly fish fed 0.25, and 0.5% of BLE had higher hemoglobulin, and hematocrit levels than fish fed 0, 0.75, and 1%. While, fish fed 0.5% had higher red blood cells than fish fed the remaining BLE levels (P<0.05). On the other hand, no marked effects for BLE supplementation were seen on the alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein, albumin, globulin, creatinine, uric acid, and urea. The regression analysis showed that the maximum dose of BLE supplementation to achieve the highest final weight and the lowest FCR is 0.46% and 0.42%, respectively.

Published: September 2022

A trial was conducted to evaluate the effect of dietary grape seed proanthocyanidin extract (GSPE) on goldfish, Carassius auratus. In this regard, GSPE was added to a basal diet at four levels including 0, 200, 400, and 600 mg/kg to produce four experimental diets including control, GSPE200, GSPE400, and GSPE600. Three hundred and sixty goldfish (3.75 ± 0.1 g) were stocked in twelve 100 L rectangular tanks (30 fish per tank) and fed with the experimental diets three times a day for nine weeks. During the experimental trial, water temperature was 26.7–28.5°C. The weight gain and specific growth rate in the fish fed with GSPE supplemented diets were higher than the control, meanwhile feed conversion ratio value in these groups decreased compared to the control. Fish fed GSPE-supplemented diets had lower fillet lipid (10–19%), but higher protein levels (7–15%) compared to the control. The levels of serum triglyceride, alanine aminotransferase and aspartate aminotransferase in the fish fed GSPE-supplemented diets were decreased compared to the control group. The highest and lowest levels of serum glucose, and ALP were in the fish fed with control and GSPE600 diets, respectively. The skin mucosal lysozyme activity (24–38%) and protein level (70–96%) were higher in fish fed GSPE-supplemented diets than the control. The highest, and lowest liver antioxidant enzymes including superoxide dismutase, catalase, and glutathione peroxidase were observed in GSPE 600 and control groups, respectively. The findings of the present study indicated that supplementing 400 mg/kg GSPE in diet can improve growth and health condition in goldfish.

Published: September 2022

Nile tilapia is recognized as a suitable candidate for intensive farming and sustainability of the aquaculture industry. However, one issue limiting Nile tilapia expansion in arid and semi-arid areas is the scarcity of freshwater resources. In this study, the supplementation of synbiotics was investigated to enhance the growth performance, growth-related genes, intestinal health, and immunity of Nile tilapia reared in inland brackish groundwater. Four diets were prepared where the basal diets were mixed with the dietary mixture of probiotics and prebiotics (Synbiotic Lactic Dry®, a blend of Saccharomyces cerevisiae, Lactobacillus acidophilus, Streptococcus faecium, and Bacillus subtilis, mannan oligosaccharides and β-1.3/1.6-D-glucan) at 0, 0.5, 1, and 2 g/kg. After eight weeks, the final weight and weight gain are linearly increasing with increasing the supplementation level of synbiotic. Markedly fish fed 0.5, 1, and 2 g/kg of synbiotic had higher final weight, weight gain, and feed intake and lower feed conversion ratio (FCR) than fish fed synbiotic free diet. The specific growth rate (SGR) was significantly higher in fish fed 1 and 2 g/kg than in fish fed 0 and 0.5 g/kg. The intestine of fish fed on synbiotic shows an increase in intestinal villi density. Further, the intestine of fish fed on synbiotic showed an increase in the length and branching intestinal villi (anterior, middle, and posterior) in a dose-dependent manner. The lysozyme and phagocytic activities were significantly different from the control, while synbiotic supplementation did not affect the phagocytic index. Interestingly, the results showed marked upregulation of ghrelin, IGF-1, and GH genes in fish fed synbiotics at 0.5, 1, and 2 g/kg. In addition, fish fed 2 g/kg had the highest expression of ghrelin, IGF-1, and GH genes. In conclusion, growing Nile tilapia in inland brackish groundwater can be achieved without negative impacts on the growth performance and health status. Supplementing synbiotics (1–2 g/kg) in Nile tilapia feeds enhanced the growth and feed performances, intestinal histomorphological features, growth-related genes, and immune response.

Published: September 2022

Recently, most outdoor localizations use a hybrid mechanism that integrating some IoT devices occupying with GPS (Anchor Nodes) and other wireless sensor nodes like LoRaWAN (without GPS-Unknown node). This hybrid method employed to achieve low power consumption and low cost solution. Our proposed framework focuses on determining the Mobile Anchor node locations with high accuracy to enhance the overall accuracy of all IoT nodes. To achieve this goal, the installation of low power consummations and low-cost localization sensors modules will be used in the proposed Anchor IoT node. These modules are the inertial measuring unit (IMU) and the low cost Global Positioning System (GPS). Then, this method will be implemented on AVR microcontroller (ATMega 128) to develop an IoT enhanced localization unit. The achieved results for our proposal show how the IoT device's state can be known accurately and at a high update rate (100 Hz, 10 milliseconds).

Using metal-organic frameworks to confine liquid samples for nanoscale NV-NMR
Authors: Liu Kristina , Ma Xiaoxin , Rizzato Roberto , Semrau Anna-Lisa , Henning Alex , Sharp Ian , Fischer Roland , Bucher Dominik
Published: September 2022

Atomic-scale magnetic field sensors based on nitrogen vacancy (NV) defects in diamonds are an exciting platform for nanoscale nuclear magnetic resonance (NMR) spectroscopy. The detection of NMR signals from a few zeptoliters to single molecules or even single nuclear spins has been demonstrated using NV-centers close to the diamond surface. However, fast molecular diffusion of sample molecules in and out of nanoscale detection volumes impedes their detection and limits current experiments to solid-state or highly viscous samples. Here, we show that restricting diffusion by confinement enables nanoscale NMR spectroscopy of liquid samples. Our approach uses metal-organic frameworks (MOF) with angstrom-sized pores on a diamond chip to trap sample molecules near the NV-centers. This enables the detection of NMR signals from a liquid sample, which would not be detectable without confinement.

Advances in solid-state nuclear magnetic resonance (NMR) methods and hardware offer expanding opportunities for analysis of materials, interfaces, and surfaces. Here, we demonstrate the application of a very high magnetic field strength of 28.2 T and fast magic-angle-spinning rates (MAS, >40 kHz) to surface species relevant to catalysis. Specifically, we present as case studies the 1D and 2D solid-state NMR spectra of important catalyst and support materials, ranging from a well-defined silica-supported organometallic catalyst to dehydroxylated γ-alumina and zeolite solid acids. The high field and fast-MAS measurement conditions substantially improve spectral resolution and narrow NMR signals, which is particularly beneficial for solid-state 1D and 2D NMR analysis of 1H and quadrupolar nuclei such as 27Al at surfaces.
Feedback Minimum Principle: Variational Strengthening of the Concept of Extremality in Optimal Control
Authors:   V.M. Matrosov Institute of System Dynamics and Control Theory SB RAS, Dykhta Vladimir
Published: September 2022

Existing maximum principles of Pontryagin’s type and related optimality conditions, such as, e.g., the ones derived by F. Clarke, B. Kaskosz and S. Lojasiewicz Jr., and H.J. Sussmann, can be strengthened up to global necessary optimality conditions in the form of so-called feedback minimum principle. This is possible for both classical and non-smooth optimal control problems without terminal constraints. The formulation of the feedback minimum principle (or related extremality conditions) remains within basic constructions of the mentioned maximum principles (the Hamiltonian or Pontryagin function, the adjoint differential equation or inclusion, and its solutions –– co-trajectories). At the same time, the actual maximum condition –– maximization of the Hamiltonian –– takes a variational form: any optimal trajectory of the addressed problem should be optimal for a specific “accessory” problem of dynamic optimization. The latter is stated over all tubes of Krasovskii-Subbotin constructive motions generated by feedback strategies, which are extremal with respect to a certain supersolution of the Hamilton-Jacobi equation. Such a supersolution can be represented explicitely in terms of the co-trajectory of a reference control process and the terminal cost function. In a general version, the feedback minimum principle operates with generalized solutions of the proximal Hamilton-Jacobi inequality for weakly decreasing (𝑢-stable) functions

This paper introduces multi–period loan interest rate Nash game models in the banking sector under regulatory solvency constraints. By taking solvency constraint as Basel II and modelling economic condition as AR(1) process, we obtain results regarding the existence of loan interest rate equilibrium. A sensitivity analysis for the solvency constraint model and some numerical results are presented.

This paper is dedicated to finding the traveling wave solutions of the loaded modified Korteweg-de Vries equation. It is shown to find the solutions via (G’/G) — expansion method which is one of the most effective ways of finding solutions. When the parameters are taken as special values the solitary waves are also derived from the traveling waves. The traveling wave solutions are expressed by the hyperbolic functions, the trigonometric functions and the rational functions. This method is easy to implement using well-known software packages, which allows you to solve complex nonlinear evolution equations of mathematical physics.

Objetivou-se avaliar a contaminação por Staphylococcus spp. resistentes à meticilina no campo operatório de cadelas submetidas à ovariohisterectomia. Foram coletadas 40 amostras de swabs de pele (um por animal). Posteriormente, essas amostras foram submetidas à análise microbiológica e molecular. Staphylococcus spp. foram identificados em 16/40 (40%) das amostras, sendo todos Staphylococcus coagulase-positivos. Na prova fenotípica de resistência aos antimicrobianos, 7/16 (43,75%) dos isolados foram resistentes à penicilina G, 8/16 (50%) à oxacilina, 2/16 (12,5%) à cefoxitina, 6/16 (37,5%) à cefalexina e 2/16 (12,5%) à amoxicilina com ácido clavulânico. Na avaliação de perfil genotípico, detectou-se o gene mecA em dois isolados e esses foram identificados através do MALDI-TOF como Staphylococcus pseudintermedius. Os dados obtidos revelaram o primeiro isolamento e identificação de Staphylococcus spp. resistentes à meticilina isolados em cães no estado de Pernambuco, Brasil. O estudo corrobora a necessidade de monitorar o perfil de resistência a antimicrobianos utilizados na medicina veterinária e alerta para o risco que patógenos multirresistentes podem causar a saúde humana e animal.

Published: September 2022

A leishmaniose visceral (LV) é uma enfermidade cosmopolita, grave e de alta letalidade em seres humanos, sendo considerada uma zoonose negligenciada. Nas Américas, a sua ocorrência está diretamente ligada com a presença do inseto vetor, principalmente relacionada à fêmea da espécie de flebotomíneo Lutzomyia longipalpis. Entretanto, em alguns estudos foram observados casos da doença em humanos e cães, com ocorrências em locais livres do vetor, indicando para a possibilidade de outras formas de transmissão, como a sexual e a vertical. O objetivo desse trabalho foi realizar uma revisão de literatura com o intuito de descrever sobre os principais aspectos relacionados com a transmissão sexual e vertical entre cães, proporcionando, assim, uma melhor compreensão da epidemiologia da doença, principalmente em áreas endêmicas. Atualmente, a possibilidade de transmissão sexual e vertical nessa espécie animal vem sendo bastante explorada, em que as pesquisas visam buscar a presença do protozoário Leishmania (L.) infantum nos órgãos do sistema reprodutivo, tanto de fêmeas quanto de machos caninos, bem como a presença do DNA do parasito no esmegma e sêmen. Dessa forma, a literatura aponta que essas formas de transmissão na LV provavelmente ocorrem em cães.
A comparative analysis of neural network function: resilient back propagation algorithm (BPA) and radial basis functions (RBF) in multilingual environment

The most convenient speech processing tool is Artificial Neural Networks (ANNs). The effectiveness has been tested with various real-time applications. The classifier using artificial neural networks identifies utterances based on features extracted from the speech signal. The proposed approach to multilingual speaker identification consists of two parts, such as a training part and a testing part. In the training part, the classifier is trained using speech feature vectors. The spoken language contains complete information, such as details about the content of the message and details about the speaker of that message. In the present work, the speech signal databases of different speakers in a multilingual environment were recorded in three Indian languages, i.e., Hindi, Marathi, and Rajasthani. The cepstral characteristics of the speech signal were extracted: Mel-Frequency Cepstral Coefficients (MFCC) and Gammatone Frequency Cepstral Coefficients (GFCC). The system is designed for speaker recognition through multilingual speech signals using MFCC, GFCC, and combined functions as acoustic characteristics. Training and testing were performed using the Neural Network (NN) function, robust Backpropagation Algorithm (BPA), and Radial Basis Functions (RBF), and the results were compared. The accuracy of the speaker identification system is 94.89% using BPA and 96.62% using the RBF neural network.

Several studies and surveys have shown that having independent mobility brings significant benefits to both children and adults. While many people with disabilities are contained in traditional or motorized wheelchairs, some of the disabled community find difficulty in using wheelchairs. Many researchers have experimented with various technologies to make the wheelchair suitable for this purpose. The proposed design includes manual control and includes a voice activation system for people with physical disabilities. This paper describes a "Voice Controlled Collision Avoidance Wheelchair" for people with disabilities in which a voice command controls the movements of the wheelchair. The voice command is transmitted through a Bluetooth-enabled cellular device, and the command is transmitted and converted to a string using BT Voice Control for Arduino, and then to an SR-04 Bluetooth module connected to the Arduino board to control the wheelchair. The project also provides for smart wheelchairs by incorporating collision avoidance systems using an ultrasonic sensor and stairwell fall protection devices to prevent wheelchairs from falling downstairs.

Published: September 2022

Introduction: The COVID-19 pandemic has led to an increase in takeout orders due to the mandated loss of dine-in options at restaurants. The significant rise in takeout has led to the use of single-use plastic containers that are currently made from materials such as polyethylene and expanded polystyrene (EPS). The aim of our research is to determine the effectiveness of Pleurotus eryngii (King oyster mushroom) based mycelium in replacing single-use takeout food containers.
Methods: Variables such as flexural strength, permeability, insulation test, interactions between food and mycelium container, and decomposability in comparison to the common EPS takeout container. Various articles from scholarly sources such as PubMed, Google Scholar, and Omni library were used to determine the anticipated results.
Results (hypothesized): The flexural strength test will be greater than or equal to 0.43 mPa. The mycelium container should be able to stop various viscosities of food from diffusing through the container due to the hydrophobicity of the mycelia. The mycelium should have greater insulation capacity than the standard EPS container. Qualitative observations obtained for interactions between the mycelium container and food should be similar to the control EPS container.
Discussion: The mycelium container will be an effective alternative to using single-use EPS containers due to all tested variables resulting in the same or greater capabilities than the EPS container.
Conclusion: Overall, using mycelium containers as an alternative to single use plastic takeout containers would reduce plastic waste and emission pollution, having a positive impact on climate change.
