Carbohydrate metabolism disorders are a serious problem during pregnancy. They are a complication in approximately 15-20% of pregnancies. The body has difficulty processing and using carbohydrates, leading to abnormal levels of glucose (sugar) in the blood. Two common pregnancy-related disorders are gestational diabetes mellitus (GDM) and pre-existing diabetes. Hypoglycemia and insulin resistance are also very common problems during pregnancy. Complications affect both the mother and the child, so it is important to know them and be able to prevent their occurrence and complications. The purpose of this literature review is to evaluate the influence of carbohydrate metabolism disorders during pregnancy and diet and physical exercise in the light of most up to date research.
Wie frei sind Gedanken?
Authors: Ulrich Martin
Published: July 2024

Beeinflusst die soziale Lage befragter Individuen ihre politische Ideologie? Martin Ulrich erforscht diesen Zusammenhang in seiner quantitativen Analyse. Er konzeptualisiert Ideologien als eine Unterart der von Ludwik Fleck entworfenen Denkstile und entwickelt die POLID-Skala, um Ideologien detailliert zu messen. Mithilfe dieser Skala erhebt er vier Ideologie-Scores (Libertarismus, Konservativismus, Sozialismus, Liberalismus), deren Trade-off die ideologische Haltung der Befragten widerspiegelt. Seine Ergebnisse zeigen eindrücklich, dass politisches Denken tatsächlich durch sozioökonomische Lebensbedingungen geprägt ist. Doch der Zusammenhang geht nicht nur in eine Richtung. Vielmehr bestimmen Ideologien einige Aspekte der sozialen Lage selbst mit. https://creativecommons.org/licenses/by-sa/4.0/legalcode

Published: July 2024

The article is devoted to the issue of training of psychological and pedagogical personnel in the system of postgraduate education as an important component of continuous education of adults. The main task of the postgraduate education system is the development, renewal and improvement of competencies previously formed at previously acquired levels of education. The professional and general competences of a specialist that meet the requirements of the qualification characteristics of professions (positions) are specified in the specialty standards of each individual field. In modern educational systems, post-graduate education is a specific element of adult education and takes a priority place, as it provides training throughout most of a person’s life and professional activity, taking into account acquired experience and personal changes. It is emphasized that, under modern conditions, society’s need for qualified personnel with a high level of professionalism and culture can be satisfied only on the basis of a new philosophy of education – “education throughout life”. It was found that the system of postgraduate education is organically integrated into the general structure of continuous education, implementing common goals and objectives, principles of continuity and continuity, ensuring comprehensive development, both professional and general. The system of postgraduate education of psychological and pedagogical workers contributes to the enrichment of professional, methodological, axiological and spiritual aspects of personality culture. In modern educational systems, postgraduate education is a specific element of adult education. It has been established that the post-graduate education system is able to modernize the professional functions of specialists, change the value system, promote the development of the individuality of psychological and pedagogical staff, update the image of a specialist and form a modern style of thinking in order to be ready to make innovative decisions in the changed and crisis conditions of today.

Authors: Tian Feng , Zhao Jing , Ding Di , Feng Jiayan , Ma Yangyang
Published: July 2024

Aims/Background: Insulinoma is an extremely rare condition in pediatric patients. This study aims to examine the pathological and clinical characteristics of pediatric insulinoma.

Methods: A retrospective, single-center study was conducted involving five pediatric patients diagnosed with insulinoma. The study involved evaluating the postoperative status of the patients during follow-up and analyzing their clinical manifestations, diagnostic work-up, pathological findings, and therapeutic approaches.

Results: The study cohort comprised four males and one female, aged between 4 and 9 years. Common symptoms included dizziness and fatigue. The insulinomas were located in various parts of the pancreas: two in the head, one in the neck, one in the body, and one in the tail. After undergoing subtotal pancreatectomy, four patients experienced no side effects during a follow-up period of 41 to 153 months. One patient, who underwent an incomplete pancreatic resection, required ongoing postoperative treatment with 150 mg Creon due to pancreatic enzyme deficiency. Postoperative pathological results indicated that all cases were low-grade neuroendocrine tumours, classified as grade 1 (G1) or grade 2 (G2). Two cases exhibited capsule invasion, and one case showed microvascular invasion. Despite these invasions, no recurrences or metastases have been observed to date.

Conclusion: Surgical resection is a viable treatment option for pediatric insulinoma, yielding a favorable prognosis. The presence of capsular and microvascular invasions does not seem to affect the overall prognosis in these cases.

Path Integral Representation Model to Extend the Analytical Capability of the Nonstandard Finite-difference Time-domain Method
Authors: Ohtani Tadao , Kanai Yasushi , Kantartzis Nikolaos V.
Published: July 2024

The nonstandard finite-difference time-domain (NS-FDTD) method is a powerful tool for solving Maxwell’s equations in their differential form on orthogonal grids. Nonetheless, to precisely treat arbitrarily shaped objects, very fine lattices should be employed, which often lead to unduly computational requirements. Evidently, such an issue hinders the applicability of the technique in realistic problems. For its alleviation, a new path integral (PI) representation model, equivalent to the NS-FDTD concept, is introduced. The proposed model uses a pair of basic and complementary path integrals for the H-nodes. To guarantee the same accuracy and stability as the NS-FDTD method, the two path integrals are combined via optimization parameters, derived from the corresponding NS-FDTD formulae. Since in the PI model, E-field computations on the complementary path are not necessary, the complexity is greatly reduced. Numerical results from various real-world problems prove that the proposed method improves notably the efficiency of the NS-FDTD scheme, even on coarse orthogonal meshes.
Simple, Method of Moments Solution for the Integral Equations for Multiple Dielectric Bodies of Arbitrary Shape in Time Domain
Authors: Rao Sadasiva M.
Published: July 2024

In this work, we present a straightforward and simple method of moments (MOM) solution procedure, with minimum mathematical manipulations, to solve the coupled integral equations for multiple, homogeneous and inhomogeneous, dielectric bodies of arbitrary shape directly in the time domain. The standard surface and volume integral equation formulations are used for homogeneous and inhomogeneous bodies, respectively. The numerical solution procedure does not involve a time-marching process as is usually adopted for time domain problems and seems to be one of the primary reasons for the late-time instabilities as a result of error accumulation. The present solution method is stable for a very long time as evidenced by several representative numerical examples presented for validation.
An Efficient MLFMA for Accurately Analyzing Electromagnetic Radiation and Coupling Characteristics of Large-scale Antenna Arrays Mounted on Platform
Authors: Yin Lei , Ding Ning , Hou Peng , Lin Zhongchao , Zhao Xunwang , Jiang Shugang , Jiao Yongchang
Published: July 2024

A multilevel fast multipole algorithm (MLFMA) for analyzing electromagnetic radiation and coupling characteristics of large-scale antenna arrays mounted on the platforms is presented in this paper. Compared with the method of moments (MoM), the MLFMA can be used to calculate larger scale problems with limited resources. First, waveport model of the MLFMA based on the equivalence principle and mode matching theory is established to efficiently and accurately simulate the antenna array. Then, a preconditioning approach for solving the radiation problems with the waveports is designed to improve convergence of the MLFMA. An initial guess construction method is proposed to accelerate the MLFMA computation for the multi-excitation problems, which can reduce the iteration time by at least 50%. Numerical results demonstrate accuracy and efficiency of the proposed method.
Dual Circularly Polarized Ultrawideband Rectenna with High Efficiency for Wireless Energy Harvesting
Authors: Liu Jian , Li Jun Yi
Published: July 2024

This paper presents an ultrawideband dual circularly polarized (CP) rectenna for wireless energy harvesting (WEH) applications. It is mainly composed of a dual CP antenna and an ultrawideband rectifier. The receiving antenna is fed by a coplanar waveguide (CPW) and it has two input ports. The proposed ultrawideband rectifier has a two-cascaded voltage doubler configuration. This configuration means the proposed rectifier’s input impedance has less sensitivity to frequency variation. Thus, a wide bandwidth can be achieved. For validation, a prototype is designed, fabricated and measured. The measured results show that the axial ratio (AR) bandwidth of the proposed rectenna is from 1.35 to 3.10 GHz (for AR <3 dB). In this frequency range, the rectenna’s power conversion efficiency (PCE) is higher than 55%. These results indicate that the proposed rectenna is highly efficient and suitable for wideband high-efficiency WEH systems.

Authors: Roganović Jelena
Published: July 2024

With current treatment protocols, over 90% of children with acute lymphoblastic leukemia (ALL) are cured. Simultaneously with these excellent results, there is an increasing importance of the recognition of possible late effects of antileukemic treatment. The most frequent late effects of therapy for childhood ALL include endocrine abnormalities, obesity, growth disturbances, neurocognitive deficits, psychosocial adverse effects, cardiotoxicity, gonadotoxicity and reproductive changes, neurotoxicity, bone toxicity, secondary malignancies, and premature late mortality. Better recognition of late effects has resulted in the modifications of treatment regimens and development of guidelines for lifelong follow-up of survivors.

Published: July 2024

Non-rhabdomyosarcoma soft-tissue sarcoma (“RMS-like” and “non-RMS-like” tumours- NRSTS) of childhood is a highly heterogeneous group of tumours. Within the subgroup of undifferentiated sarcomas (UDS), new entities have been described based on molecular markers found through increasingly available genetic analysis in the new 2020 classification of the World Health Organization (WHO). In recent years, the importance of genetic analysis and the detection of molecular tumour markers has been growing due to the possibility of targeted therapy application and the determination of prognosis or disease course. We will present two patients with soft tissue sarcoma and neurotrophic tyrosine receptor kinase (NTRK) gene rearrangement, focusing on excellent therapeutic response to NTRK inhibitor targeted therapy with good drug tolerance.
Welfare States in Wealthy Democracies
Authors: Gingrich Jane
Published: July 2024

The contemporary study of the welfare state began, along with World Politics, in the immediate
postwar era, inspired by the near-collapse of democracy and the crucial role envisaged
for public spending in stabilizing it after war. Over the following decades key scholarly
questions focused on the normal welfare politics of the era—distributive politics,
the effects of government policy on growth, and the capacity of social policies to create
their own political constituencies. In a new era of more uncertain democratic resilience,
we may need to return to older questions: of the coercive function of the welfare state, of
its ability/inability to conserve democracy, and of the weaknesses of welfare policies to
maintain political support.
Seedless Velocimetry of High-Enthalpy Hypersonic Boundary Layers by Nitric-oxide Ionization Induced Flow Tagging and Imaging at 100 kHz
Authors: Leonov Boris , Jiang Naibo , Siddiqui Farhan , Roy Sukesh , Miles Richard
Published: July 2024

This letter describes the first demonstration of a velocity measurement by Nitric-oxide ionization induced Flow Tagging and Imaging (NiiFTI) of a high-enthalpy hypersonic flow utilizing naturally formed nitric oxide. The measurements were conducted in the Hypervelocity Expansion Tunnel at Texas A&M University in Mach 8.5 and Mach 10 flows near an ogive test article. The region of interest contained boundary layers and the hot flow region between the boundary layer and the oblique shock front. The boundary layer profiles were recorded with the velocity ranging between 2516 m/s and 985 m/s measured as close as 0.5 mm to the model surface. Single-shot measurement in the core flow showed an average velocity of 2.5 km/s with a slight decelerating trend. Overall, NiiFTI demonstrated a good performance in high-enthalpy hypersonic flow, extending its usability to reacting environments.

Published: July 2024

Electric-field oscillations are now experimentally accessible in the THz-to-PHz frequency range. Their measurement delivers the most comprehensive information content attainable by optical spectroscopy – if performed with high sensitivity. Yet, the trade-off between bandwidth and efficiency associated with the nonlinear mixing necessary for field sampling has so far strongly restricted sensitivity in applications such as field-resolved spectroscopy of molecular vibrations. Here, we demonstrate electric-field sampling of octave-spanning mid-infrared waves in the 18-to-39 THz (600-to-1300 cm-1) spectral region, with amplitudes ranging from the MV/cm level down to a few mV/cm. We show that employing powerful short-wave mid-infrared gate pulses is key to approaching the ultimate detection limit of capturing all photons in the temporal gate, as well as to providing high linearity with respect to the detected mid-infrared field. This combination of detection sensitivity, dynamic range and linearity enables exploitation of the full potential of emerging high-power waveform-controlled infrared sources for (non-)linear spectroscopy of solids, liquids and gases.
The effectiveness of group interpersonal synchrony in young autistic adults’ work environment: A mixed methods RCT study protocol
Authors: Dvir Tamar , Rabinowitch Tal-Chen , Elefant Cochavit
Published: July 2024

Introduction

Few autistic adults are able to integrate successfully into the world of work given their difficulties adapting to the social and stressful aspects of work environments. Interpersonal synchrony, when two or more individuals share body movements or sensations, is a powerful force that consolidates human groups while promoting the ability to self-regulate and cooperate with others. The abilities to self-regulate and cooperate are crucial for maintaining a calm and productive work environment. This study protocol outlines research that aims to assess the effects of group interpersonal synchrony on prosociality and work-related stress of young autistic adults in their work environment.

Methods and analysis

This mixed-methods randomized controlled trial will investigate two movement-based group synchronous and non-synchronous intervention conditions. The sample will be composed of young adults enrolled in an innovative Israeli program designed to integrate cognitively-abled 18- to 25-year-old autistic adults into the Israeli army work force. The movement-based intervention sessions will take place in groups of 10–14 participants, once a week for 10 weeks. Questionnaires, behavioral collaborative tasks and semi-structured interviews will be conducted. Quantitative data will be collected for each participant at three points of time: before and after the intervention period, and 17 weeks after the end of the intervention. Qualitative data will be collected after the intervention period in interviews with the participants.

Discussion

Little is known about interventions that promote successful integration into social and stressful work environments. The findings are likely to shed new light on the use of group interpersonal synchrony in autistic individuals at work.

Spaces
Authors: Brezavšček Pia
Published: July 2024

An individual or a group of people with a space to live in and create, where they don’t fear eviction and, at the same time, where others are welcome too feel good in their community; they feel heard and at home. This is a space of learning how to live together and negotiate the community’s shared values, what society is and what it can become. A space that accepts us and that we are a part of, that shapes us, gives us integrity and, last but not least, gives us a sense of belonging and the possibility of positioning that we, the dispossessed, as eternal guests or individuals not yet or no longer belonging to the space, do not have.
Feudalisation of open public space
Authors: Zanuik Tomaž
Published: July 2024

“Privatisation happens in many ways. [...] The fundamental characteristic of public space – its universal accessibility for all – is endangered by increasing control and surveillance.”I Social segregation also contributes to feudalisation, which is another attack on public space. Although no one is talking about it yet, the initial casualties of this feudalisation – due to increased restrictions and costs for accessing public spaces that must be purchased – will not only be fire brigades and other organisers of commercial and entertainment events, including festivities, but also, similar to the scarcity of production spaces, producers of cultural noise or non-profit events in the realm of independent and non-governmental arts and culture.
Beyond vandalism: Gentle privatism and the graffiti code of conduct in Block 45
Authors: Nikolić Sara
Published: July 2024

This paper explores the unique interplay between graffiti practices, ‘gentle privatism’, and urban space in Block 45, a large housing estate in New Belgrade. Focusing on the informal code of conduct adhered to by local graffiti artists, the study examines how these unwritten rules shape social hierarchies and community dynamics. Through an analysis of graffiti’s territoriality and its role in place-making, the paper reveals how artists navigate the tension between public and private domains, challenging conventional neoliberal urban paradigms. By appropriating public spaces, graffiti writers transform common walls into valuable canvases that reflect the collective identity and mutual respect within the ambience of Block 45. The paper argues that this form of gentle privatism not only asserts the presence of the artists but also enriches the urban landscape and strengthens community bonds. Ultimately, the study highlights the sociocultural significance of graffiti as a medium for cultural expression and social commentary within the context of privatism.
Revising or repeating conventions?

Published: July 2024

Jaka Bombač writes about Masterwork for Six Dancers, a dance performance by Emese Cuhorka, Csaba Molnár and En-Knap Group, modelling itself on the Bauhaus philosophy and the Triadic Ballet that explores the ways in which the body sheds cultural symbols and social meanings. The author wonders if the performing procedures associated with the Triadic Ballet and other avant-garde forms have not themselves become a convention. He concludes that the semiotic logic of the post-industrial world is completely different from the semiotic logic of the industrial world which, he believes, makes it unclear whether the performance subverts conventions or merely repeats them.

However, traditional transit systems often contribute to environmental degradation through emissions. Recognising this challenge, nations such as India are actively pursuing strategies to reduce energy consumption and carbon emissions. An important initiative involves integrating electric buses into urban transit systems. To optimise the effectiveness of these electric bus services and encourage greater public transportation usage, it is essential to align service offerings with customer needs and expectations. This research aims to assess customer satisfaction among electric bus users in Aligarh using the Customer Satisfaction Index (CSI) analysis. Critical attributes such as affordability, safety, comfort, and accessibility will be examined to identify areas for improvement. An analysis will be conducted to gain insights into service quality attributes crucial for enhancing customer satisfaction in public transportation operations and the strategies for improving customer satisfaction to be defined.
Revolutionizing Kashmir’s tandoor design: improving health, efficiency, and productivity with reduced smoke emissions
Authors: Zargar Aquib Manzoor , Rather Rayees Ahmad , Khan Mohammad Mohsin
Published: July 2024

In recent years, the traditional Tandoor, a key tool in bread preparation, has undergone a significant transformation driven by scientific advancements and ergonomic improvements. The conventional Tandoor historically lacked scientific refinement and ergonomic considerations, leading to problems like smoky work environments, direct hand contact with hot surfaces, and substantial heat loss. This study focuses on the innovative redesign of the Tandoor, with a focus on efficiency, health, production, and smoke reduction. The new Tandoor design features a cuboidal core with a deflector at the rear and multiple vertical channels integrated within the oven. These channels significantly increase the bread-baking surface area, with the deflector redirecting flue gases towards them to expedite baking. Bread production benefits from dual heat sources: initial heat from fuel combustion and secondary heat via altered flue gas flow, reducing the average gas temperature from 250 to 180 oC. Ergonomically, the Tandoor is designed with the outer surface at a convenient 2.5 feet above the ground to improve accessibility for the baker. A strategically positioned chimney effectively directs smoke away from nearby individuals due to its frustum shape. The Tandoor and channels are insulated with Praech, a specialized material to minimize heat loss. Detailed thermal analysis validated the design's efficiency, enhancing baker working conditions while addressing smoke-related concerns and improving production efficiency.
Numerical characterization of solar radiation applied to a simplified five parameters diode model of a photovoltaic module in the city of Ngaoundere

Published: July 2024

In this paper, another simple and accurate approach to reconstructing the characteristics of a photovoltaic (PV) array exposed to solar radia-tion has been presented. This approach uses a five-parameter diode model. The approach is based exclusively on the manufacturer's data (three-point method: short-circuit current, open-circuit voltage, maximum power point). To carry out this work, we first carried out a numer-ical characterization of local solar radiation in the city of Ngaoundere. We then established the mathematical equations describing a solar photovoltaic module, and ran a numerical simulation on Matlab Simulink under standard conditions. The electrical parameters of the photo-voltaic generator and its optimal electrical quantities (current, voltage and power) were analyzed as a function of meteorological variations (temperature, irradiance) and series resistance. The simulation results show that we can achieve a maximum solar irradiance of 1214.9W/m2 in the city of Ngaoundere at solar noon. It has been shown that increasing solar irradiance is one of the most productive factors in a PV module. It was also shown that increasing temperature and series resistance considerably reduces the performance of a solar photovoltaic module. This result has enabled us to confirm that these PV cells perform best in a cold, clear-sky environment.

Published: July 2024

In this study, convective heat and mass transfer during papaya drying in a parallel airflow were simulated. The aim of this work was to con-sider the boundary conditions at the leading and trailing edges in the coupled and simultaneous resolution of the heat and mass transfer equations to better predict papaya drying kinetics. The Luikov equations established for this transfer model were discretized by the implicit finite-difference method and then solved simultaneously using the MATLAB 2014 tool. The drying process was simulated under the influ-ence of drying air conditions and product thickness. The results showed that for the moisture ratio, the mean relative errors were 5.21% and 3.89% for the model without and with boundary conditions set at the leading and trailing edges, respectively. Similarly, the results showed that for product temperature, the mean relative errors were 4.35% and 3.61% for the model without and with boundary conditions set at the leading and trailing edges, respectively. Comparison of the predicted models with the experimental data satisfactorily demonstrated that in-corporating the leading and trailing edge boundary conditions in a transfer model enabled better prediction of drying kinetics than the model without the leading and trailing edge boundary conditions.

Published: July 2024

In this article, attention is paid to the use of photovoltaic electricity for the popularization of off-season agriculture in arid Sahelian areas. Here we propose an efficient solar drip irrigation model for rational use of water for off-season crops. The model of the proposed sys-tem is developed in the MATALAB/Simulink environment. The results of simulations based on field data specific to the cultivation of off-season onions in the locality of PITOA (North Cameroon) are obtained for a cultivable area of 1 hectare, according that the area to be irrigated is 7200 m². The algorithm developed for determining the soil capacity made it possible to evaluate the useful reserve at 1.70 mm/cm. Under the set test conditions (temperature 25°C, irradiance 1000 W/m²), the water flow provided by a dripper is estimated at 20 l/h. To meet the water needs of crops, the power of the photovoltaic generator is 1600 W peak.

Power transformers are important components of electrical systems. Their failures are very costly, mainly because of the unavailability of electrical service they cause. Rapid and accurate diagnosis of internal transformer faults is a key factor of efficient and safe operation. Such diagnosis is usually carried out by experts. Several methods of power transformer windings diagnosis exist. The online diagnosis, the interpretation of results and the identification of various internal winding faults are criteria to be taken into account when choosing a method. The voltage-current method is a powerful method that has been successfully used as a diagnostic technique to detect power transformer winding faults. In this work we propose a mathematical models of power transformers winding faults based on voltage-current method. To achieve our goal, we modelled the transformer winding as a distributed network of similar R-L-C circuits. Then we used Matlab/Simulink to simulate the different winding faults on a number of discs ranging from 5 to 120. We defined four failures indicators and we studied their evolution for each fault. At the end we give for each fault the corresponding mathematical model. The transformer used in this work is a 15 MVA 22/0.415 kV distribution power transformer.

Aggregates are the world's most widely exploited resource, surpassing even fossil fuels. They are mainly used for concrete production. On the one hand, due to restrictions on the use of river sand in some parts of the world to conserve river beds, demand for alternative fine aggregates in the construction sector has increased considerably. The need to characterize and continuously update local and site-specific information on crushed aggregates and natural sand, in order to stimulate optimal use, is essential. As a contribution to strengthening the use of local aggregates in civil engineering, this study focuses on the characterization of aggregates. The various analyses enabled us to determine properties such as specific weight, grading class, flattening coefficient (only for crushed aggregates) and sand cleanliness (sand equivalent). Densities (apparent and absolute) meet the specifications of standard NF EN 12620, which stipulates an apparent density of between 1300 kg/m³ and 1600 kg/m³ and an absolute density of between 2500 kg/m³ and 2700 kg/m³. The results revealed a fineness modulus of 1.8. In view of this result, the sand complies with the requirements of standard NF P 18-541, which sets a fineness modulus of between 1.8 and 3.2, depending on the deposit, and requires an optimum modulus of 2.5. The (LA) results for 5/15 and 15/25 aggregates give values of 20.2% and 28.8% respectively. Analysis of the results shows that the aggregates studied are acceptable for concrete production.

In the current scenario machine learning is the branch of artificial intelligence being used in every field and medicine is one of them. In medical science, the use of machine learning techniques aims to improve patient care by collecting, and analyzing patient data, and designing advanced and intelligent tools and/or devices for disease detection using collective experience. ML technology detects patterns associated with specific diseases by analyzing large datasets that include various patient records, such as diabetes, blood pressure, cholesterol, X-rays, MRIs, CT scans, imaging data, and genomic information. ML algorithms compute the primary symptoms of the disease. Based on these calculations the disease is identified. Here it is necessary to have sufficient dataset and/or features for computation. The understanding of the ML model depends on the underlying feature to be used to identify the related problem. The fairness of a machine learning algorithm depends on which symptoms are selected to determine any disease. The selection of features for ML models is an important task, more or less features can make the model underfit or overfit. Incorrect determination of selected features can introduce bias into the model which can greatly affect the accuracy of the model. If the bias in the machine learning model is not properly tuned or the bias is tuned too high or too low then the prediction does not cover the underlined pattern. Diseases arise in different circumstances; each disease has its special characteristics. To cover all the basic parameters of each disease is a very tough task. If a basic attribute is missed and/or an attribute that has no relation to the disease is captured then the desired result of the model may be affected. In the proposed research paper, the feature selection problem and bias effect have been analyzed through the Support Vector Machine (SVM) and Logistic Regression (LR) algorithm.

Starch and cellulose are high molecular weight polysaccharides consisting of carbon, hydrogen and oxygen compounds. One effort that can be made to increase profits from avocado seeds is to transform them into bioethanol. Avocado seeds contain 43.3% amylase, 37.7% amylopectin and 55.07% carbohydrates. The physical properties of waste tea dregs have large surface area and fast adsorption kinetics, which makes waste tea dregs good for use as an environmentally friendly adsorbent. The method is carried out using the Bioethanol Adsorption-Distillation process with activated tea lees. FTIR results of avocado seeds contain C-O, C=O, N=O groups, C=C double bonds, C=C triple bonds, C-H triple bonds and –OH groups, which are a group of carbohydrates containing polysaccharides which can be used as raw material for the manufacture of ethanol and tea dregs contain C-O, C=O, N=O groups, C=C double bonds, C= triple bonds C, C-H triple bonds and –OH groups are carbohydrates, so tea dregs can be used as a raw material to increase bioethanol levels. The results of bioethanol levels using adsorbent and distillation reached high values with a bioethanol refractive index of 1.7575 and an ethanol content of 28% compared to the initial ethanol content of 11.5%.
