Relevance of the work. Black shale horizons may reflect abrupt paleoclimate changes. In the northeast of the Ulyanovsk-Saratov Trough (UST), two black shale horizons widely occur, the Middle Volgian Promzino Formation and the Lower Aptian Ulyanovsk Formation. Despite years of research, the role of paleoclimate in their accumulation is still under discussion. The aim of the research was to assess the climate as a factor of the accumulation of the Middle Volgian and Lower Aptian organic carbon-rich deposits in the northeastern UST. Methods. To reconstruct paleoclimate and to evaluate its impact on the black shale deposition, a comprehensive isotope study of calcitic and aragonitic shells of several groups of benthic and pelagic organisms was performed. Besides, the lithological and geochemical features of organic carbon-rich and host deposits were studied using optical microscopy, XRD, and pyrolysis. Results. Isotope study allowed to construct benthic and pelagic palaeotemperature curves and to reconstruct paleoclimate in the UST during the formation of black shales. Based on these data and data on lithological and geochemical features of sediments, the depositional mechanisms of the Promzino and Ulyanovsk Formations were clarified. Conclusions. No causal link has been revealed between climate changes and the deposition of the Middle Volgian black shales. At the end of the Middle Volgian, a short-term cooling has been recorded, probably related to the volcanic activity of the northern Tethyan margin. The Lower Aptian black shales were formed during the hyperthermal. This hyperthermal controlled the accumulation of organic carbon-rich sediments by increasing the input of nutrients and/or providing conditions for its stratification and stagnation.

Relevance. Issues related to the operation of hydrocyclones in the asbestos industry for the separation of finely split asbestos fibers from rock impurities and non-fluffed asbestos needles used in the wet enrichment of brittle chrysotile asbestos, as well as some types of amphibole asbestos and in the purification of commercial grades of chrysotile asbestos of normal strength from magnetite are considered. Purpose. The purpose and objectives of the research is to study the operating modes of a hydrocyclone for the separation and desliming of asbestos products. Particular attention is paid to the behavior of particles inside the hydrocyclone. Methodology. The formulas presented in the literature for calculating the volumetric delivery of hydro-cyclones are analyzed. As a result, it was determined that the volumetric delivery of the hydrocyclone does not depend on the size of the sand nozzle and that the influence of the latter affects mainly the specific distribution of water between the discharge and sand products. Results. In the course of processing the obtained experimental data, the calculation results showed that, at different nozzles and feed heads, the movement of grains of separation mesh in the internal flow of hydrocyclones of the tested design occurs within 1 < Re < 20. Therefore, the accepted dependences of Ψ on Re when deriving the calculated formulas are correct. Conclusions. The volumetric delivery of hydrocyclones D = 75 mm and D = 200 mm of the tested design for feeding and draining depends on the feed head and the diameter of the framework nozzle. The established regularities in the behavior of particles of asbestos concentrates in hydrocyclones are of practical importance and can be used when choosing the technological parameters of their operation to achieve the specified conditions for the size of particle separation mesh.

The indiscriminate use of herbicides makes weeds resistant, increasing the demand for more efficient herbicides. Novel potential herbicides were prepared from sorbic acid, being 8 dienamides and 6 epoxides. Subsequently, phytotoxic activities of sorbic acid and 14 synthesized compounds were evaluated against sorghum, onion, cucumber, lettuce, and beggartick seeds. Furthermore, the protein target of the most active substance in plants was identified in silico. Among the tested compounds, (2E,4E)-N-(p-fluorophenyl)hexa-2,4-dienamide (2c), (2E,4E)-N-(o-naphthyl) hexa-2,4-dienamide (2d), (E)-N-methylphenyl-3-((2R,3R)-3-methyloxiran-2-yl)acrylamide (3b), (E)-N-bromophenyl-3-((2R,3R)-3-methyloxiran-2-yl)acrylamide (3e), and (E)-N-methoxyphenyl3-((2R,3R)-3-methyloxiran-2-yl)acrylamide (3f) showed pronounced inhibitory activities, both of shoots and roots, making them candidates for promising herbicides. All compounds altered seed development, and compounds 2c, 2d, 3b, 3e, and 3f presented equal or superior results to the commercial control herbicide S-metolachlor. Docking studies suggest that enzyme mitogenactivated protein kinase can be the target of those compounds.

Published: July 2023

The industrial water contamination with synthetic dyes is currently a cause for concern. This paper introduces composite hydrogels as alternative scavengers of soluble dyes.

This research used kinetic models and adsorption isotherms to test composite exopolysaccharide hydrogels extracted from Nostoc commune V., pectin, and starch for their ability to remove methylene blue from water.

The exopolysaccharides demonstrated a rather low extraction yield and a crystallinity percentage of 38.21%. However, the crystallinity increased in the composite hydrogels (48.95%) with heterogeneous surface. The pseudo-second-order kinetic model served to explain the adsorption mechanism at pH 8 and pH 11, while the Elovich model explained the adsorption mechanism at pH 5. When in acid fluid, the hydrogels had a heterogeneous surface, whereas alkaline fluid resulted in a homogeneous surface. The Temkin adsorption model showed a good fit in the treatments.

At a basic pH value, composite exopolysaccharide-based hydrogels showed good results as scavengers of low-concentration methylene blue.
A global synthetic analysis of the effects of reclaimed water irrigation on crop yield and water use efficiency

Published: July 2023

To quantitatively evaluate the effect of RW irrigation on yield, WUE, and IWUE, and identify aqueous, edaphic, and management factors that favor improved yield, WUE, and IWUE compared to control practices, a meta-analysis was conducted. The results indicated that RW irrigation is beneficial for improving crop yields, WUE, and IWUE (16.8, 23.8, and 18.7%, respectively). However, its effectiveness is highly dependent on the aqueous, edaphic, and management factors of the studies evaluated. Greater responses were found in practices using RW with a pH < 7 or a nitrogen content <100 mg/L. The soils with a pH ≥ 7, electrical conductivity between 2 and 4 dS/m, bulk density <1.35 g/cm3, and/or initial nitrogen content between 200 and 2,000 mg/kg produced the highest effect size. Furthermore, using a surface drip irrigation system, with a nitrogen fertilizer rate <1,000 kg/ha and irrigation level at 100% crop evapotranspiration are effective ways to use RW. Our findings highlight the potential of RW irrigation to improve crop yield, WUE, and IWUE and identify the conditions under which these results can be achieved. These results can provide a better understanding of RW irrigation and guide the practice of RW utilization in the future.

In recent years, it has become especially vital to identify prognostic risks of health disorders in workers exposed to harmful occupational factors. This is necessary for substantiating an occupational origin of a disease and biomarkers of exposure and for optimizing the occupational risk assessment methodology. The aim of this study was to compare and analyze immunochemical markers of effect (cytokines, heat shock proteins, and neuronal antibodies (AB)) in blood serum of patients with vibration disease (VD) induced by exposure to different types of vi-bration in order to substantiate the most informative diagnostic risk indicators concerning the disease development and clinical course. Cytokines, heat shock proteins, and antibodies to regulatory proteins of nervous tissue were identified in blood by ELISA tests. We established unidirectional statistically significantly more apparent changes in patients who had VD caused by combined exposure to both whole body vibration and local vibration against those who had VD caused by exposure to local vibration only. These changes included hyperactivated pro-inflammatory reactions of the immune response (IL-1β, TNF-α, INFγ), growing concentrations of antibodies to proteins: S-100, MBP, NF-200, GFAP, and voltage-gated Ca-channel. The differences were that patients with VD under combined exposure to both types of vibration had greater production of pro-inflammatory IL-8 and HSP27 whereas people with VD caused by exposure to local vibration only had a decrease in HSP70 levels. The study results confirmed more apparent neuro-immune inflammation in patients with VD caused by combined exposure to both whole body vibration and local vibration. This may indicate more significant risk factors of the disease and gives an opportunity to identify the most sensitive biomarkers eligible for diagnosing VD of different etiogenesis.

Authors: Tolou-Ghamari Zahra
Published: July 2023

Background:

More than 175,000 new cases of cancer in children are diagnosed every year worldwide.

:

This study aimed to investigate the recorded cancer frequency in children and adolescents in Isfahan Province, Iran.

:

As one of the main reasons for death among children and adolescents is reported as cancer with different prevalence worldwide, therefore,
reporting the occurrence of cancers in this population is crucial.

Methods:

Information from the years between 2013 to 2015 related to the Surveillance, Epidemiology, and End Results; (SEER) was collected from the Isfahan Cancer Registry. The cancer sites studied were defined according to the International Classification of Diseases and recorded by related topography codes.

Results:

Among all 30,465 registered cancers, there were 582 cases (2%) of cancer, including 57% of children and 43% of adolescents. The mean ± SD age of patients was 11.5 ± 5.9 years (Min; 1, Max 19). The top four ranked cancers were (n=264; 45%) comprised of; 1) hematopoietic and reticuloendothelial system (n= 122), 2) secondary and unspecified malignant neoplasm of lymph nodes (n=56), 3) malignant neoplasm of the brain (n=43) 4), thyroid gland (n=43). Death-reported data was associated with 32% of the total population studied. The neoplasm was reported in 174 cases, which was associated with 95% death.

Conclusion:

This frequency source of childhood cancers could be used for health strategy. The observed variations in the frequency of different cancers require continuous monitoring and investigation. Therefore, plan of health-system should focus based on greater efforts toward advanced evidence-based drug therapy in Iran.
Efferocytosis and Metabolic Syndrome: A Narrative Review
Authors: Amirinejad Ali , Khayyatzadeh Sayyed Saeid , Rezaeivandchali Noushin , Gheibihayat Seyed Mohammad
Published: July 2023

Metabolic syndrome (MetS), which is distinguished by the simultaneous
presence of hyperglycemia, dyslipidemia, hypertension, and central obesity, is a critical
risk factor for cardiovascular disease (CVDs), mortality, and illness burden. Eliminating
about one million cells per second in the human body, apoptosis conserves homeostasis
and regulates the life cycle of organisms. In the physiological condition, the apoptotic
cells internalize to the phagocytes by a multistep process named efferocytosis. Any
impairment in the clearance of these apoptotic cells results in conditions related to
chronic inflammation, such as obesity, diabetes, and dyslipidemia. On the other hand,
insulin resistance and MetS can disturb the efferocytosis process. Since no study
investigated the relationship between efferocytosis and MetS, we decided to explore the
different steps of efferocytosis and describe how inefficient dead cell clearance is
associated with the progression of MetS.

Published: July 2023

Introduction:

Fibrosarcoma of bone is a rare malignant spindle cell tumor.

Case Study:

Herein, we present a case of fibrosarcoma in a 40-year-old male who was presented to the clinic with left-sided great toe pain for 20 years. Simple radiographs showed acrolysis at the distal phalanx of great toe. Magnetic resonance imaging (MRI) revealed a 1.5 cm sized heterogenous high signal intensity mass on T2-weighted images and iso signal intensity on T1- weighted images. Dorsal and distal portion of the mass showed markedly dark signal intensity on T1 and T2-weighted images.

Conclusion:

In an enhanced image, the mass showed heterogenous enhancement. Surgical removal was performed and pathologic analysis revealed fibrosarcoma. Although extremely rare, fibrosarcoma of the bone should be kept in mind as a possibility when a lesion exhibits a black signal intensity component on an MRI with acrolysis.

Published: July 2023

This research aimed to determine the effect of work stress and organizational culture on employee performance in the Palembang Ilir Barat Tax Service Office. The population in this study were all employees at KPP Pratama Palembang Ilir Barat, totaling 145 employees, and all of them were samples in the study using the census method. The results of multiple linear analyses show that work stress and organizational culture positively and significantly affect employee performance. Work stress, on the individual stressor dimension, significantly affects employee performance. There needs to be an evaluation to provide a workload following the job desk and employee responsibilities. If the work in some parts of the division has a more significant number of jobs, then it is necessary to adjust the number of employees according to the needs and workload given. With frequent leadership changes, organizational culture requires employees to get used to the established work rhythm. The change in leadership position is expected to be carried out at least 2-3 years after the change is made. The need for adaptation felt by employees causes a decrease in performance because not all employees can quickly adapt to changes in the ever-changing leadership cycle.

Introduction: Even with the increased use of telehealth from the COVID-19 pandemic onward, there needs to be more knowledge about its usability for patients with non-communicable diseases from the point of view of the health professional, which is the main objective of this study. The secondary objectives will be to describe the user’s profile, discuss the usability of telehealth in different contexts and correlate it with the characteristics of the user’s profile. Methods: Protocol of the cross-sectional, prospective, multicenter, international study involving Brazil, Ghana, Honduras, and the United Kingdom. We will evaluate the usability of telehealth systems with an electronic form with the usability questionnaire of the Usability Scale System (SUS). The study has obtained ethical approval in each country and will be carried out independently. This analysis will consider the use context, such as country and geosocial conditions, age, gender, profession, and user experience. We will analyze usability (continuous dependent variable) with simple statistics with measures of central tendency. We will use ANOVA/Kruskal Wallis to analyze the usability difference between countries. If there are differences, we will use Bonferroni post hoc tests (p<0.05). We will use the Pearson/Spearman correlation coefficient to correlate the characteristics of the user’s profile with usability. If the dependent variable data are normally distributed, we will use linear regression to correct for known confounders. Discussion: Studying the usability of a system allows for understanding the subjective factors that determine its practical use, improving the experience of human-computer interaction.
Light absorption enhancement in organic solar cell using non-concentric Ag:SiO2 core-shell nanoparticles
Authors: Muldarisnur Mulda , Fahendri F. , Perdana Ilham , Abdullah Zulfi , Yusfi Meqorry
Published: July 2023

Low solar energy conversion efficiency prevents the widespread of organic solar cells; hence, metal nanoparticles have been used to overcome this problem without increasing cell thickness. We investigated light absorption enhancement in view of the embedment of Ag:SiO2 core-shell nanoparticles of different shell thicknesses, core offsets, offset orientation angles, and vertical mismatches between neighboring particles. The simulations were carried out using the finite element method. This is the first investigation in the use of asymmetric nanoparticles. At optimized conditions, absorption enhancement up to 345% compared to the one without the nanoparticles could be achieved. The enhancement was found much higher than that of the published values. The enhancement results were mainly from the increase of near-field localization and scattering in the active layer of solar cells due to the excitation of Fano resonances. The resonance occurred due to the non-symmetric nature of the core-shell nanoparticles.
General Characteristics and Design Taxonomy of Chatbots for COVID-19: Systematic Review
Authors: Lim Wendell Adrian , Custodio Razel , Sunga Monica , Amoranto Abegail Jayne , Sarmiento Raymond Francis
Published: July 2023

Background

A conversational agent powered by artificial intelligence, commonly known as a chatbot, is one of the most recent innovations used to provide information and services during the COVID-19 pandemic. However, the multitude of conversational agents explicitly designed during the COVID-19 pandemic calls for characterization and analysis using rigorous technological frameworks and extensive systematic reviews.

Objective

This study aims to describe the general characteristics of COVID-19 chatbots and examine their system designs using a modified adapted design taxonomy framework.

Methods

We conducted a systematic review of the general characteristics and design taxonomy of COVID-19 chatbots, with 56 studies included in the final analysis. This review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to select papers published between March 2020 and April 2022 from various databases and search engines.

Results

Results showed that most studies on COVID-19 chatbot design and development worldwide are implemented in Asia and Europe. Most chatbots are also accessible on websites, internet messaging apps, and Android devices. The COVID-19 chatbots are further classified according to their temporal profiles, appearance, intelligence, interaction, and context for system design trends. From the temporal profile perspective, almost half of the COVID-19 chatbots interact with users for several weeks for >1 time and can remember information from previous user interactions. From the appearance perspective, most COVID-19 chatbots assume the expert role, are task oriented, and have no visual or avatar representation. From the intelligence perspective, almost half of the COVID-19 chatbots are artificially intelligent and can respond to textual inputs and a set of rules. In addition, more than half of these chatbots operate on a structured flow and do not portray any socioemotional behavior. Most chatbots can also process external data and broadcast resources. Regarding their interaction with users, most COVID-19 chatbots are adaptive, can communicate through text, can react to user input, are not gamified, and do not require additional human support. From the context perspective, all COVID-19 chatbots are goal oriented, although most fall under the health care application domain and are designed to provide information to the user.

Conclusions

The conceptualization, development, implementation, and use of COVID-19 chatbots emerged to mitigate the effects of a global pandemic in societies worldwide. This study summarized the current system design trends of COVID-19 chatbots based on 5 design perspectives, which may help developers conveniently choose a future-proof chatbot archetype that will meet the needs of the public in the face of growing demand for a better pandemic response.
Clinical case of steroid-dependent nephrotic syndrome in a child
Authors: Lagodych Ye. , Ivanov D. , Vakulenko L. , Lytvynova O.
Published: July 2023

Nephrotic syndrome (NS) is a common glomerular pathology encountered in pediatric practice. The main clinical signs are massive proteinuria, hypoalbuminemia, hyperlipidemia, and edema. Among all cases of NS, 75 % of children have a histological variant of glomerular lesions in the form of minimal change di­sease that is sensitive to hormone therapy, but easily leads to relapse and steroid dependence. These children often need to extend the time of taking hormonal drugs or add other immunosuppressants, which can have significant toxicity. Available immunosuppressant treatment options include cyclophosphamide, cyclosporine A, tacrolimus, and mycophenolate mofetil. The use of rituximab is a possible alternative treatment for steroid-dependent nephrotic syndrome in children. However, the efficacy and safety of ritu­ximab in the treatment of childhood steroid-dependent nephrotic syndrome is still controversial. The purpose was to evaluate the efficacy and safety of rituximab treatment in a child with steroid-dependent nephrotic syndrome on the example of a clinical case from our own practice.
Mythological Criticism of a Turkish Folk Narrative Poem
Authors: Mobarak Vahid
Published: July 2023

The word “hapsane” is another form of the word “usane” and “legend” and the poem “hapsane ha hapsane” is one of the common poems in the language of Azeri-speaking people of West Azerbaijan. This legendary poem, with its simplicity and sincerity and having most of the basic features of folklore, includes mythological elements such as travel, the companionship of the wise old man, meta-realities, magic, etc., which gives it a special privilege. It reveals the reason for its permanence and reputation. It is clear that folk tales have a strong connection with myths and by eliminating time and place and in the transcendental space of the ethnic unconscious, they connect the wishes and the very distant past to the present time. This research, using a descriptive-analytical method and a library study, has tried to show that folktales, along with being related to good and goodness and the way of collective production and having elements of life, are related to the beyond and are of mythological contrasts. O like the system of two elements of good and evil; pragmatism in national or ethnic spirit; They have the vividness of the whole existence and the archetype of traveling and searching for the father, ... and with the help of all these elements, they invite people to goodness. On the one hand, they are a tool to preserve the indigenous and ancient culture, and on the other hand, with all hope, they are the foundation for the upbringing and education of the new generation based on the good and popular teachings embedded in the collective unconscious.

Published: July 2023

Abstract: Many of the existing machine learning models for health care analysis are concentrating on one disease per analysis. Like one analysis is for diabetes, one for cancer, one for skin diseases like that. There is no common system where one analysis can perform more than one disease prediction. In case of doctor is not available we can use this model. In this model we are proposing a system which used to predict multiple diseases by using Spyder API. In this model we used to analyse Diabetes prediction, Heart disease prediction and parkinson’s disease prediction analysis. We also developed a model in extension with that based on symptoms it can predict the diseases. To implement multiple disease analysis used machine learning algorithms, streamlit and Spyder API. Python pickling is used to save the model behaviour and python unpickling is used to load the pickle file whenever required. The importance of this model analysis in while analysing the diseases all the parameters which causes the disease is included so it possible to detect the maximum effects which the disease will cause. For example for diabetes analysis in many existing systems considered few parameters like age, sex, bmi, insulin, glucose, blood pressure and pregnancies are considered.

Abstract: Construction industry is one of the biggest and fast-growing industry in India which is providing employment to millions of people and also contributing for economic development of nation. But the major and common problem faced by this industry is cost overrun and time overrun. Therefore, there is need to study this topic. This research paper will help to understand cost and time overrun in construction project. Hence the main aim of these paper is to identify the factors affecting cost overrun and time overrun in construction project and provide suitable strategies to avoid it. Method used in this research is both quantitative and qualitative method. Interviews were taken from some of the experienced professionals in this industry and questionnaire survey is conducted to collect data from the respondent from contractor, consultant, clients and students. Total 81 respondent participated in the survey. From the result it is seen that for estimating cost, 73% respondent and for estimating time, 89% respondent use combination of calculation and experience. From the study it is also understood that the problem of cost and time control is not only about the techniques being used it is also about the poor management of techniques and poor supervision. Cost overrun refers to when project goes beyond the estimated cost and factors affecting cost overrun is Poor Estimate, Design changes, Scope creep, Delays, Inflation, Poor project management, Unforeseen site conditions, Material and labour cost fluctuations and Contractual disputes. Time overrun is when project get delayed beyond estimated schedule and factors affecting time overrun is Project Planning, Design Changes, Weather Conditions, Workforce Productivity, Unforeseen Conditions, Regulatory and Permitting Issues, Coordination and Communication. Based on this recommendation were given with some strategies to avoid cost and time overrun in construction projects they are Accurate cost estimation, Risk assessment, Effective project management, change management and Communication. Further research is required in project control providing a checklist for the same, so that major points can be taken care of
"Proper" Shift Rules for Derivatives of Perturbed-Parametric Quantum Evolutions
Authors: Theis Dirk Oliver
Published: July 2023

Banchi & Crooks (Quantum, 2021) have given methods to estimate derivatives of expectation values depending on a parameter that enters via what we call a "perturbed" quantum evolution x↦ei(xA+B)/ℏ. Their methods require modifications, beyond merely changing parameters, to the unitaries that appear. Moreover, in the case when the B-term is unavoidable, no exact method (unbiased estimator) for the derivative seems to be known: Banchi & Crooks's method gives an approximation.In this paper, for estimating the derivatives of parameterized expectation values of this type, we present a method that only requires shifting parameters, no other modifications of the quantum evolutions (a "proper" shift rule). Our method is exact (i.e., it gives analytic derivatives, unbiased estimators), and it has the same worst-case variance as Banchi-Crooks's.Moreover, we discuss the theory surrounding proper shift rules, based on Fourier analysis of perturbed-parametric quantum evolutions, resulting in a characterization of the proper shift rules in terms of their Fourier transforms, which in turn leads us to non-existence results of proper shift rules with exponential concentration of the shifts. We derive truncated methods that exhibit approximation errors, and compare to Banchi-Crooks's based on preliminary numerical simulations.
Semi-device-dependent blind quantum tomography

Extracting tomographic information about quantum states is a crucial task in the quest towards devising high-precision quantum devices. Current schemes typically require measurement devices for tomography that are a priori calibrated to high precision. Ironically, the accuracy of the measurement calibration is fundamentally limited by the accuracy of state preparation, establishing a vicious cycle. Here, we prove that this cycle can be broken and the dependence on the measurement device's calibration significantly relaxed. We show that exploiting the natural low-rank structure of quantum states of interest suffices to arrive at a highly scalable `blind' tomography scheme with a classically efficient post-processing algorithm. We further improve the efficiency of our scheme by making use of the sparse structure of the calibrations. This is achieved by relaxing the blind quantum tomography problem to the de-mixing of a sparse sum of low-rank matrices. We prove that the proposed algorithm recovers a low-rank quantum state and the calibration provided that the measurement model exhibits a restricted isometry property. For generic measurements, we show that it requires a close-to-optimal number of measurement settings. Complementing these conceptual and mathematical insights, we numerically demonstrate that robust blind quantum tomography is possible in a practical setting inspired by an implementation of trapped ions.
Persaingan Politik Dua Penguasa Besar Dunia Islam Abad 15 M: Sultan Bayazid dan Timur Lenk
Authors: Fatianda Septian
Published: July 2023

After the fall of the Abbasid dynasty in 1258 due to the attack of the Mongols, the mecca of great Islamic power began to move to the Ottoman Empire and the Timurid Empire. The two great powers were led by Sultan Bayazid and Timur Lenk, respectively. The development and power possessed by these two rulers brought them to the point where they competed with each other in spreading political influence. Policies to undermine each other's territory are inevitable. They finally met in the great war in 1402 in Ankara. The war was finally won by Timur Lenk's troops and Sultan Bayazid became a prisoner of war. The paper uses historical methods that focus on literature review to find sources and present research answers. This paper aims to describe the causes of political competition and its implications for the Islamic world at that time.

This study aims to describe the forms of violation of the principles of cooperation in the first part of the Ahlul Kahfi drama. And knowing the conditional meaning of implicature in the first part of the ahlul kahfi drama. To achieve this goal, descriptive qualitative research is used by analyzing and collecting the script of the play in the form of conversations between characters using the theory of violation of the principle of Grice's cooperation which gave birth to the conversational implicature. This method can provide a conclusion that in the script of the first part of the Ahlul Kahfi drama there are several violations  against the principles of cooperation namely the violation of quality maxims, violations of quantity maxims and violations of relationship maxims, and there is no violation of the maxim of means. And the meaning born of the implicature of the conversation due to the violation of the principle is adapted to the context of the speech.
