Indirect Additive Manufacturing: A Valid Approach to Modulate Sorption/Release Profile of Molecules from Chitosan Hydrogels
Authors: Moreira Mariana F. , Kanaan Akel F. , Piedade Ana P.
Published: June 2022

This work studied the influence of hydrogel’s physical properties (geometry and hierarchical roughness) on the in vitro sorption/release profiles of molecules. To achieve this goal, chitosan (CS) solutions were cast in 3D-printed (3DP) molds presenting intricate shapes (cubic and half-spherical with/without macro surface roughness) and further immersed in alkaline solutions of NaOH and NaCl. The resulting physically crosslinked hydrogels were mechanically stable in aqueous environments and successfully presented the shapes and geometries imparted by the 3DP molds. Sorption and release profiles were evaluated using methyl orange (MO) and paracetamol (PMOL) as model molecules, respectively. Results revealed that distinct MO sorption/PMOL release profiles were obtained according to the sample’s shape and presence/absence of hierarchical roughness. MO sorption capacity of CS samples presented both dependencies of hierarchical surface and geometry parameters. Hence, cubic samples without a hierarchical surface presented the highest (up to 1.2 × greater) dye removal capacity. Moreover, PMOL release measurements were more dependent on the surface area of hydrogels, where semi-spherical samples with hierarchical roughness presented the fastest (~1.13 × faster) drug delivery profiles. This work demonstrates that indirect 3DP (via fused filament fabrication (FFF) technology) could be a simple strategy to obtain hydrogels with distinct sorption/release profiles.

Published: June 2022

Cellulose nanospheres (CN) have been considered a leading type of nanomaterial that can be applied as a strengthening material in the production of nanocomposites. This work aimed to isolate and characterize the properties of CN from different agricultural by-products. CNs were successfully isolated from rice straw, corncob, Phulae pineapple leaf and peel using acid hydrolysis (60% H2SO4) combined with homogenization-sonication (homogenized at 12,000 rpm for 6 min and ultrasonicated for 10 min). The results showed that the CN from rice straw (RS-CN) and corncob (CC-CN) exhibited high yields (22.27 and 22.36%) (p < 0.05). All hydrolyzed CNs exhibited a spherical shape with a diameter range of 2 to 127 nm. After acid hydrolysis, Fourier transform infrared (FTIR) results showed no impurities. X-ray diffraction (XRD) showed that the structure of cellulose was changed from cellulose-I to cellulose-II. However, cellulose-I remained in pineapple peel cellulose nanosphere (PP-CN). The crystalline index (CI) ranged from 43.98 to 73.58%, with the highest CI obtained in the CC-CN. The CN from all sources presented excellent thermal stability (above 300 °C). The functional properties, including water absorption Index (WAI), water solubility index (WSI) and swelling capacity were investigated. PP-CN showed the highest WAI and swelling capacity, while the PL-CN had the highest WSI (p < 0.05). Among all samples, CC-CN showed the highest extraction yield, small particle size, high CI, and desirable functional properties to be used as a material for bio-nanocomposites film.

Authors: Dastoorian Farnia , Pakzad Leila , Kozinski Janusz , Behzadfar Ehsan
Published: June 2022

Inhalation therapy involving a pressurized metered-dose inhaler (pMDI) is one of the most commonly used and effective treatment methods for patients with asthma. The purpose of this study was to develop a computational fluid dynamics (CFD) model to characterize aerosol flow issued from a pMDI into a simulated mouth–throat geometry. The effects of air flow rate and cone angle were analyzed in detail. The behaviour of the multiphase flow initiated at the inhaler actuation nozzle and extended through the mouth–throat airway was simulated based on the Eulerian-Lagrangian discrete phase model, with the k-ω model applied for turbulency. We validated our model against published experimental measurements and cover the hydrodynamic aspect of the study. The recirculation we observed at the 90° bend inside the mouth–throat airway resulted in the selective retention of larger diameter particles, and the fluid flow patterns were correlated with drug deposition behaviour. Enhancing air flow rates up to three times reduced the aerodynamic particle diameters to 20%. We also observed that, as cone angle increased, mouth deposition increased; an 8° cone angle was the best angle for the lowest mouth–throat deposition.

Authors: Na Wenbo , Zan Qi , Gao Yanfeng , Guo Siyu , Wang Zheng
Published: June 2022

Fault diagnosis is studied based on the system type, which facilitates the realization of the engineering configuration and improves the diagnosis efficiency. The fault-tolerant control method is unified based on the concept of fault compensation. According to the dynamic characteristics of the system, the method takes the boundary value of no-fault signal fluctuation as the basis for fault detection, then takes the changing intensity of the solenoid valve control signal after the fault occurs as the fault location basis. Finally, it takes the difference or ratio of the signals before and after the fault occurs as the fault estimation. For the basis of fault separation, the integral value of the fitting equation between the fault signal and time is used as the Eigenvalue of fault type separation to comprehend fault separation. A program is written in C++ and combined with MATLAB/S-Fun function to realize fault tolerance. At the same time, the dynamic model calibration and real-time fault diagnosis, and fault-tolerant control process of sensor fault diagnosis are provided, which makes it suitable for general engineering feedforward-feedback systems and has a certain suppression effect on noise. The simulation results verify that the method is not only viable and it is exact.
Combined Grey Wolf Optimizer Algorithm and Corrected Gaussian Diffusion Model in Source Term Estimation
Authors: Liu Yizhe , Jiang Yu , Zhang Xin , Pan Yong , Qi Yingquan
Published: June 2022

It is extremely critical for an emergency response to quickly and accurately use source term estimation (STE) in the event of hazardous gas leakage. To determine the appropriate algorithm, four swarm intelligence optimization (SIO) algorithms including Gray Wolf optimizer (GWO), particle swarm optimization (PSO), genetic algorithm (GA) and ant colony optimization (ACO) are selected to be applied in STE. After calculation, all four algorithms can obtain leak source parameters. Among them, GWO and GA have similar computational efficiency, while ACO is computationally inefficient. Compared with GWO, GA and PSO, ACO requires larger population and more iterations to ensure accuracy of source parameters. Most notably, the convergence factor of GWO is self-adaptive, which is in favor of obtaining accurate results with lower population and iterations. On this basis, combination of GWO and a modified Gaussian diffusion model with surface correction factor is used to estimate the emission source term in this work. The calculation results demonstrate that the corrected Gaussian plume model can improve the accuracy of STE, which is promising for application in emergency warning and safety monitoring.
Marking Scriptural Figures as Sacred Names
Authors: Rodenbiker Kelsie G.
Published: June 2022

The use of scriptural names is a basic building block of ancient paideia as it is represented by Philo and Christian ecclesiastical writers after him. After learning letters, and then syllables, students would learn words (ὀνόματα), including through lists of onomastica intended to aid students both in learning to write and in ordering the world. I argue that the grammatical-ethical instruction that is found in Philo’s and early Christian writers’ investment in the practice of writing names in the process of paideia is also evident in the paratextual practice of marking sacred names. Lists variously attributed to Pseudo-Dorotheus, Pseudo-Epiphanius, and Pseudo-Hippolytus attest to the onomastic tradition preserved in manuscripts, while the names of scriptural figures have been marked almost as nomina sacra in the texts of 3 Corinthians, Jude, and 1 and 2 Peter, which were bound with the Bodmer Composite Codex.

Authors: Fakhri Moloud , Yousefi Seyde Sedighe , Moosazadeh Mahmood , Azadbakht Mohammad , Fakheri Hafez
Published: June 2022

Introduction: Green tea drinking is one of the traditional methods to prevent colorectal cancer (CRC). The present study proposes a systematic review and meta-analysis approach to investigate the relationship between green tea drinking and CRC risk. Materials and Methods: The literature survey has been carried out using the previously published studies in the Google Scholar search engine and various electronic databases, including Scopus, Cochrane, Web of Science, Embase, and PubMed. The review process has continued until July 13, 2021. Besides, the Q test and I2 index were employed to evaluate the heterogeneity of the studies. STATA 14 software has been conducted to analyze the gathered dataset. It is essential to note that the significance level for statistical tests was set to 5% (P value < 0.05). Results: The results of 18 studies accomplished on 44,992 patients aged 19-80 years have been used to compute the relative risk of green tea consumption in CRC (OR [odds ratio] = 0.99; 95% CI: 0.83-1.18), colon (OR=0.97; 95% CI: 0.85-1.10), and rectum (OR=1; 95% CI: 0.86-1.16). Although green tea consumption was a protective factor in Asia and the United States, it was considered a risk factor in Australia. The general population studies classified green tea as a risk factor for CRC, while hospital studies considered this product as a protective factor. Conclusion: The findings showed that green tea had the most significant effect on reducing the colon cancer risk, while it had the minimum influence on CRC. Additionally, it did not affect rectal cancer. It is essential to note that these relationships were not statistically significant. Registration: The current protocol was also registered on PROSPERO (#CRD42021276257, https://www.crd.york. ac.uk/prospero/display_record.php?ID=CRD42021276257).

Authors: Aramesh Mohammad Reza , Malakian Arash , Hosseinzadeh Mohsen , Dehdashtian Masoud , Rostami Shahrebabaki Mohammad
Published: June 2022

Introduction: Patent ductus arteriosus (PDA) is a common disorder in premature infants which causes heart failure. Platelets and C-reactive protein (CRP) play an important role in closure. Objectives: The purpose of this study was to evaluate serum CRP and plasma platelet count in preterm infants with PDA compared to infants without PDA. Patients and Methods: This case-control study was conducted on premature infants with PDA admitted to Imam Khomeini hospital in Ahvaz, Iran (2020-2021). A group of 120 infants with inclusion criteria was selected and divided into two groups of 60 subjects. The preterm infant with PDA and without PDA was defined as the case and control group, respectively. Platelet count, serum CRP, and an echocardiogram were assessed in all infants. The subjects were matched by gender, gestational age, and birth weight. Results: The mean platelet count was 194.67±74.03 (×103 /mm3 ) in the neonate with PDA, and it was significantly lower than in neonate without PDA (P=0.04). The mean of serum CRP was significantly different in neonates with PDA (11.62±5.96 mg/L) compared to neonates with closed arterial ducts (8.52±3.97 mg/L; P=0.002). Additionally, PDA was associated with high platelet distribution width (PDW). Conclusion: The findings of this study revealed that PDA is associated with a low-number of platelets and high serum levels of CRP in preterm neonates. It is suggested that further studies with a higher sample size on platelet count and/or function be performed in PDA patients to understanding more about the cause of PDA and to discover novel and beneficial aims in these cases

Published: June 2022

Context: Hypertension has been identified as the world’s third leading cause of death. Due to their cost-effectiveness and lack of adverse effects compared to antihypertensive medications, medicinal plants have gained popularity in most countries. The olive leaf is one of these plants. As a result, the purpose of the current systematic review and meta-analysis was to determine the effect of olive leaf consumption on systolic and diastolic blood pressure. Evidence acquisition: The following domestic and international databases were searched in order to retrieve relevant studies: PubMed, Scopus, Web of Science, Embase, Cochrane, ProQuest, and Google Scholar search engine, the ClinicalTrials.gov Protocol Registration and Results System (PRS), the ISRCTN registry administered by BioMed Central, and the World Health Organization’s (WHO) International Clinical Trials Registry Platform. The data collected were analyzed using STATA software (version14) at a significance level of P<0.05. Results: Olive leaf consumption had a significant effect on systolic blood pressure [-0.87 (95% CI: -1.09, -0.64)] and diastolic blood pressure [-0.39 (95% CI: -0.57, -0.21)] in five studies with a sample size of 145 people (mean age range of 33.30 ± 5.25 years). Consumption of olive leaves also decreased cholesterol levels [-0.52 (95% CI: -0.81, -0.22)], low-density lipoprotein (LDL-c) levels [-0.35 (95% CI: -0.58, -0.12)], and triglycerides levels [-0.67 (95% CI: -1.19, -0.16)]. Nonetheless, the olive leaf had no statistically significant effect on reducing highdensity lipoprotein levels. Conclusion: We observed that olive leaf consumption significantly reduced the levels of systolic and diastolic blood pressure, cholesterol, triglycerides, and LDL-c. Registration: The current protocol was also registered on PROSPERO (ID: 221277, Date: 16.04.2022).

Authors: Hajian Sepideh , Seifzade Moosa
Published: June 2022

Introduction: Catheter-related infection in the patients with end-stage renal disease (ESRD) is one of the leading causes of death. Identifying risk factors for infection, including patients’ iron profile, plays an important role in preventing this complication. Objectives: In this study, we aimed to determine the risk factors of catheter-related infections among the ESRD patients in Qazvin, Iran. Patients and Methods: In this observational study, 41 patients with hemodialysis venous catheter-related infection (case group) and 42 patients without catheter-related infection ( control group) in Qazvin educational and medical centers were studied. The definition of functional iron deficiency anemia included ferritin <500 ng/mL and serum iron/total iron-binding capacity (TIBC) <30%. The laboratory evaluation method was based on enzyme-linked immunosorbent assay method. Definition of catheter-related infection in this study consisted of two positive results of the three cultures from blue and red catheter lines and blood at the same time with the same microorganism. Results: In studying iron parameters, a significant difference between serum iron levels and transferrin saturation in the two groups was detected (P values of 0.0016 and 0.003, respectively). Both parameters were higher in the control group. The most common microorganism causing the infection was Staphylococcus aureus (43.9%) and most of the catheters used were of temporary internal jugular vein types. The most important risk factors in the incidence of catheter infection were diabetes mellitus (OR = 5.059) and high serum iron levels (OR = 1.053). Decreased transferrin saturation levels reduced the risk of infection (OR = 0.825). Conclusion: There was a relationship between iron profile and diabetes mellitus and the increased risk of catheter-related infections. To prevent infection, patients with ESRD undergoing hemodialysis with venous catheters, blood sugar and serum iron levels need to be monitored carefully and iron overdose should be prevented in these patients.

In this study, we aimed to systematically optimize the operating parameters in the degradation and mineralization of tetracycline by Fenton process. For this purpose; optimum values were found for Fe2+ concentration, H2O2 concentration and pH, reaction time, sedimentation times which are effective operating parameters in Fenton process. In this study where initial tetracycline concentration was used as 100 mg/L; optimum values were found as 4 for pH, 30 mg/L for Fe2+ concentration, 100 mg/L for H2O2 concentration and 10 min for reaction time and 90 min for sedimentation time. Under these conditions, the TC degradation was 100%, while the COD removal efficiency was approximately 94%. As a result of kinetic studies, BMG is the most suitable kinetic model in terms of tetracycline degradation, while it is seen that the
most suitable kinetic model for tetracycline mineralization in terms of COD is the first-order kinetic model. The cost of removing 1 kg of tetracycline from the unit costs of chemicals and energy used in the Fenton process was found to be 1.527$.

Published: June 2022

Clustering is a data mining method for grouping data that have similar or different characters in each section. One of the methods is using K-Means by measuring the distance between clusters using the shortest distance or Euclidean Distance. K-means entails weakness, which is the determination of clusters in k-means clustering, resulting in the different data grouping and affecting the results of the data cluster distribution. To overcome this issue, the elbow creation method is employed to determine the similarity level in the cluster by observing the comparison between Root Means Square and R Square to measure the homogeneity and heterogeneity of the cluster where this method is applied by considering the changes in the comparison between the RMSSTD (Root Means Square Standard Deviation) and RS (R Squared) values which have the intersection of the RMSSTD and RSquared values. The difference between RMSSTD cluster 1 and RMSSTD cluster 2 was 0.066 and RS cluster 1 and RS cluster 2 was -0.304. Based on those figures, the highest difference was found in cluster 2. All considered, tourist destinations in East Asia frequently visited or interested to visitors are grouped into cluster 2, comprising criteria 6, 7, 8, and 10, or in other words, resort destination, picnic area, beaches, and religious institutions

Published: June 2022

The Torrance Test of Creative Thinking (TTCT) is the most widely used norm-referenced creativity test used in gifted identification. Although commonly used for identifying talent, little is known about how creativity tests, like the TTCT-Figural, contribute to the probability of being identified as gifted especially with underrepresented populations. Using nominated students (n = 1191) from a diverse midsized urban school district, this study examined the differential predictive validity among student demographics (i.e., race/ethnicity, free/reduced lunch status, English Learning status, sex) and the TTCT-Figural to the probability of being identified as gifted. Results of a multilevel hierarchical generalized linear regression indicated underrepresented groups showed no difference in the probability of being identified after controlling for cognitive ability and academic achievement; the same was true when the TTCT-Figural was included within the model. The inclusion of the TTCT-Figural does contribute to the probability of identification, however, the disproportionality of underrepresented student groups remains in the school district. Gifted administrators looking to enhance equity may not find the solution with the mere inclusion of a creativity assessment. Implications for practice and future directions are discussed.

Introdução: O sorriso gengival é caracterizado pela exposição exagerada da gengiva, causando uma desarmonia estética no conjunto: dentes, gengiva e lábio. Para a realização de seu diagnóstico, é necessário que o cirurgião dentista tenha total conhecimento dos fatores etiológicos e dos padrões relacionados à estética gengival, para que, com isso, seja possível a elaboração de um plano de tratamento adequado. Justificou-se a temática mediante a importância da abordagem acerca da correção do sorriso gengival por intermédio da cirurgia plástica periodontal, culminando em resultados satisfatórios e uma excelente recuperação do paciente, além de um ótimo custo-benefício. Objetivo: Avaliar as indicações da cirurgia plástica periodontal para a correção do sorriso gengival. Método: Trata-se de uma revisão integrativa de literatura, cuja pergunta norteadora foi: Quando a cirurgia plástica periodontal para a correção do sorriso gengival deve ser indicada? O corpus da pesquisa foi baseado em consultas a bases de dados on-line. Foram utilizados estudos indexados nas bases de dados online: PubMed (National Library of Medicine National Institutes of Health dos EUA), SciELO (Scientific Electronic Library Online) e BVS (Biblioteca Virtual em Saúde). A amostra foi selecionada a partir dos seguintes critérios de inclusão: artigos que tratem sobre o tema correção do sorriso gengival; artigos disponíveis em português e inglês publicados entre 2012 e 2022. Resultados e discussão: A busca na literatura resultou em 06 artigos, nos quais se observou que a cirurgia plástica periodontal apresenta resultados satisfatórios na correção do sorriso gengival, sendo apontada como uma alternativa para pacientes que procuram uma maior harmonia no sorriso, justificando a alta demanda por procedimentos estéticos nas clínicas odontológicas, especialmente pela busca por mais qualidade de vida, autoestima e satisfação pessoal. Ante aos estudos destacados na presente revisão, evidenciou-se a satisfação dos pacientes, ausência de complicações no pós-operatório e a viabilidade dos procedimentos na correção do sorriso gengival. Conclusão: Conforme evidenciado, os procedimentos plásticos periodontais para correção do sorriso gengival são cada vez mais procurados nas clínicas odontológicas, visando o alinhamento da estética bucal por meio de um sorriso harmônico, havendo a simetria com a estrutura labial.

Existence of weak solutions for a $p(x)$-Laplacian equation via topological degree
Authors: Ait Hammou M. , Rami E.H.
Published: June 2022

We consider the $p(x)$-Laplacian equation with a Dirichlet boundary value condition $$ \begin{cases} -\Delta_{p(x)}(u)+|u|^{p(x)-2}u= g(x,u,\nabla u), &x\in\Omega,\\ u=0, &x\in\partial\Omega. \end{cases} $$ Using the topological degree constructed by Berkovits, we prove, under appropriate assumptions, the existence of weak solutions for this equation.
The Savage principle and accounting for outcome in single-criterion nonlinear problem under uncertainty
Authors: Zhukovskii V.I. , Zhukovskaya L.V. , Samsonov S.P. , Smirnova L.V.
Published: June 2022

In the middle of the last century the American mathematician and statistician professor of Michigan University Leonard Savage (1917-1971) and the well-known economist, professor of Zurich University (Switzerland) Jurg Niehans (1919-2007) independently from each other suggested the approach to decision-making in one-criterion problem under uncertainty (OPU), called the principle of minimax regret. This principle along with Wald principle of guaranteed result (maximin) is playing the most important role in guaranteed under uncertainty decision-making in OPU. The main role in the principle of minimax regret is carrying out the regret function, which determines the Niehans-Savage risk in OPU. Such risk has received the broad extension in practical problems during last years. In the present article we suggest one of possible approaches to finding decision in OPU from the position of a decision-maker, which simultaneously tries to increase the payoff (outcome) and to reduce the risk (i.e., “to kill two birds with one stone in one throw”). As an application, an explicit form of such a solution was immediately found for a linear-quadratic variant of the OPU of a fairly general form.
Numerical method for system of space-fractional equations of superdiffusion type with delay and Neumann boundary conditions
Authors: Ibrahim M. , Pimenov V.G.
Published: June 2022

We consider a system of two space-fractional superdiffusion equations with functional general delay and Neumann boundary conditions. For this problem, an analogue of the Crank-Nicolson method is constructed, based on the shifted Grünwald-Letnikov formulas for approximating fractional Riesz derivatives with respect to a spatial variable and using piecewise linear interpolation of discrete prehistory with extrapolation by continuation to take into account the delay effect. With the help of the Gershgorin theorem, the solvability of the difference scheme and its stability are proved. The order of convergence of the method is obtained. The results of numerical experiments are presented.
Pursuit-evasion differential games with Gr-constraints on controls
Authors: Samatov B.T. , Akbarov A.K. , Zhuraev B.I.
Published: June 2022

In the paper, a pursuit-evasion differential game is considered when controls of the players are subject to differential constraints in the form of Grönwall's integral inequality. The strategy of parallel pursuit (briefly, $\Pi$-strategy) was introduced and used by L.A. Petrosyan to solve simple pursuit problems under phase constraints on the states of the players in the case when control functions of both players are chosen from the class $L_\infty$. In the present work, the $\Pi$-strategy is constructed for a simple pursuit problem in the cases when control functions of both players are chosen from different classes of the Grönwall type constraints, and sufficient conditions of capture and optimal capture time are found in these cases. To solve the evasion problem, we suggest a control function for the Evader and find sufficient conditions of evasion. In addition, an attainability domain of the players is constructed and its conditions of embedding in respect to time are given. Results of this work continue and extend the works of R. Isaacs, L.A. Petrosyan, B.N. Pshenichnyi, A.A. Chirii, A.A. Azamov and other researchers, including the authors.
On regularization of the Lagrange principle in the optimization problems for linear distributed Volterra type systems with operator constraints
Authors: Sumin V.I. , Sumin M.I.
Published: June 2022

Regularization of the classical optimality conditions - the Lagrange principle and the Pontryagin maximum principle - in a convex optimal control problem subject to functional equality and inequality constraints is considered. The controlled system is described by a linear functional-operator equation of second kind of the general form in the space $L_2^m$. The main operator on the right-hand side of the equation is assumed to be quasi-nilpotent. The objective functional to be minimized is strongly convex. The derivation of the regularized classical optimality conditions is based on the use of the dual regularization method. The main purpose of the regularized Lagrange principle and regularized Pontryagin maximum principle is to stably generate minimizing approximate solutions in the sense of J. Warga. As an application of the results obtained for the general linear functional-operator equation of second kind, two examples of concrete optimal control problems related to a system of delay equations and to an integro-differential transport equation are discussed.
On flexibility of constraints system under approximation of optimal control problems
Authors: Chernov A.V.
Published: June 2022

For finite-dimensional mathematical programming problems (approximating problems) being obtained by a parametric approximation of control functions in lumped optimal control problems with functional equality constraints, we introduce concepts of rigidity and flexibility for a system of constraints. The rigidity in a given admissible point is treated in the sense that this point is isolated for the admissible set; otherwise, we call a system of constraints as flexible in this point. Under using a parametric approximation for a control function with the help of quadratic exponentials (Gaussian functions) and subject to some natural hypotheses, we establish that in order to guarantee the flexibility of constraints system in a given admissible point it suffices to increase the dimension of parameter space in the approximating problem. A test of our hypotheses is illustrated by an example of the soft lunar landing problem.
Intersections in The City: The Ermenek Coverings
Authors: YILMAZ ERKOVAN Nisa
Published: June 2022

The streets, which provide the connection between the neighborhoods, and which are the smallest structures in a city where neighborhood relations are established, and the structures of this city, present a different character in the Ermenek District of Karaman Province. The streets of this city, which are located on very rough terrain, are designed to adapt to the topography. Most of the buildings were built adjacent to each other, there are no other spaces apart from the street spaces. Therefore, as a result of bringing together the urban configuration and streets within the framework of an organic union, these passages, which allow the street to continue, are strengthened with coverings, which are called “örtme” in Turkish. The topic of the study is conducted on the following four main themes: (1) the spatial readings to be made on coverings, (2) the construction of coverings in the traditional street texture, (3) the discussion of the relations of coverings with the individual, the city, and the environment, (4) the typological classification of coverings. In this context, as the methodology of the study, field studies, that is, on-site observation, detection and documentation studies, were carried out in the first stage. Afterward, a typological classification was made by examining the place of coverings in urban fiction through literature and field studies. In conclusion, urban, spatial and physical readings of the coverings, which have an influential position in the traditional street texture, were carried out. With this study, the significance of such structures, which reflect the living culture of the people, which began to disappear by being forgotten in the rural architectural structuring, in the history of architecture and urbanism was emphasized.
