Bioremediation is a process that utilizes the degradation potential of microorganism to provide a cost-effective and reliable\rapproach for pesticide biodegradation. For this purpose, chosen bacteria Sphingomonas melonis and Bacillus muralis were isolated\rfrom an agricultural soil sample. The biodegradation performance of these isolated bacteria at different Diquot Dipremide-\r(ethylene-d4) (DDE4) herbicide concentrations (250, 500 and 1000 ppm) was investigated under submerged culture conditions.\rBiodegradation performance of isolated bacteria was monitored with COD, TOC and, BOD5 reduction rates in culture medium at\rdifferent incubation periods. According to the results; S. melonis has the highest bioremediation capacity for COD removal (91%\rat 250 ppm). For TOC, B. muralis has the highest removal rate as 82% at 250 ppm. On the other hand, For BOD5 at 250 ppm 85%\rS. melonis showed the best removal performance. Most effective removal rate at 250 ppm concentrations was obtained as 91%\rand 88 by S. melonis and B. muralis respectively at the end of the 216th hour for COD. Additionally, the increase in turbidity\rrelated with population dynamics at the end of the 216 th hour positively effected the bioremediation parameters included COD,\rTOC and BOD5 reductions. These results showed that it can be used for effective COD, TOC and BOD5 removal in S. melonis and\rB. muralis on DDE4 remediation

In this study, we construct a convex Bezier type diagonal section which uniquely characterizes the Archimedean copula. The proposed diagonal section is flexible according to its polynomial degree; hence, we can add the additional parameters to the diagonal section by increasing the polynomial degree. We also present a graphical tool based on the diagonal section in order to visualize the different types of Archimdean copulas in the copula test space. As an illustration, the real data examples are given.

Korkmaz, Meral
The world is facing drought, and over time, water problems are becoming more serious. Agricultural land and green areas are gradually declining due to water scarcity. While the amount of available water is gradually decreasing, people's unnecessary use of water and water consumption are increasing. This, in turn, requires the accurate use of existing water resources and the realization of intelligent building systems as soon as possible. Despite this fact, none of the university's public buildings currently use systems such as the rainwater harvesting technique. The main aims of this research are to find effective results in terms of savings and to contribute to avoiding water shortages in the future. It is important today to immediately begin making future housing with these systems and to integrate these intelligent systems into public buildings, especially incorporating the latest technologies. In this study, the advantages of zero-energy built roofs and rainwater harvesting systems on the Munzur University campus are evaluated.

Polat, Alper; Kaya, Yusuf
In this study, the problem of discontinuous contact in two functionally graded (FG) layers resting on a rigid plane and loaded by two rigid blocks is solved by the finite element method (FEM). Separate analyzes are made for the cases where the top surfaces of the problem layers are metal, the bottom surfaces are ceramic and the top surfaces are ceramic and the bottom surfaces are metal. For the problem, it is accepted that all surfaces are frictionless. A two-dimensional FEM analysis of the problem is made by using a special macro added to the ANSYS package program The solution of this study, which has no analytical solution in the literature, is given with FEM. Analyzes are made by loading different Q and P loads on the blocks. The normal stress (sigma y) distributions at the interfaces of FG layers and between the substrate and the rigid plane interface are obtained. In addition, the starting and ending points of the separations between these surfaces are determined. The normal stresses (sigma x, sigma y) and shear stresses (tau xy) at the point of separation are obtained along the depth. The results obtained are shown in graphics and tables. With this method, effective results are obtained in a very short time. In addition, analytically complex and long problems can be solved with this method.

Altin, Mustafa; Yoldas, Halil Ibrahim; Ünal, Inan
In this study, some geometric properties of N(k)-contact metric manifolds, which are important class of contact manifolds, have been investigated by using a special connection (CY-connection). First, we give some fundamental results on N(k)-contact metric manifolds admitting CY-connection. Then, we obtain curvature properties of such manifolds. We prove that an N(k)-contact metric manifold admitting R* (xi, X).R* = 0 condition is an N (-1/4) metric manifold, where R* is the Riemannian curvature tensor of CY-connection. Also, we examine an N(k)-contact metric manifold admitting CY-connection under W* (xi, X).S* = 0 condition for generalized quasi-conformal curvature tensor W* of CY-connection. Finally, we consider a 3-dimensional N(k)-contact metric manifold admitting CY-connection.

Long-distance energy pipeline pass under roads, subjecting them to repeated stress and posing pipeline safety problems. To simulate the effects of vehicles driving over energy transmission pipeline, this paper examines large-caliber buried pipelines in the suburbs. In this study, a mechanical action model of vehicle-soil-pipeline (VSP) interactions to transform the process of a vehicle driving into the dynamic process of a load changing with time in the specified area was created. The VSP model was used to analyze the influence of moving load and position on the structural characteristics of the pipeline section. An equivalent solution method with high precision and high calculation efficiency was proposed. The results showed that as the loading position approaches the pipeline or the load increases, the stress value at the top of the pipeline gradually exceeded the stress value at the bottom of the pipeline and became the area with the maximum stress value. The minimum stress location also changed from the lower half near the pipeline bottom (Point D-135°) to the upper half near the pipeline top (Point B-45°or Point H-315°). Using the polynomial fitting method, the stress values of the maximum points were equivalently converted. Under the premise of considering pipeline safety, the most suitable functional relationship for the moving load equivalent model was obtained.

Gülmez, Nihan
Due to its fine particle size, waste marble slurry originating in cutting and processing units mixes into the air after drying, causing environmental and health problems in nearby areas. On the other hand, large amounts of iron particles are generated as metalworking industry waste, affecting the environmental system. In this study, 0%, 10%, and 20% marble powder (instead of cement) and iron particles (instead of fine aggregate) were used in mixtures, and the composites produced were subjected to two different curing periods: 7 and 28 days. The physical, mechanical, microstructural, and thermal properties of the fresh and hardened composites were ascertained via bulk density, consistency, porosity, water absorption, capillary water absorption, strength tests, particle size distribution, X-ray diffraction (XRF), X-ray fluorescence (XRF), scanning electron microscopy and energy dispersive spectroscopy (SEM–EDS), and thermogravimetric analyses (TGA). The results revealed that minimum water absorption (8.5%) and porosity (19.8%) values were achieved in 28-day composites produced with 10% marble–20% iron wastes among all composites. Thus, iron particles substituted for natural aggregates were mainly responsible for the increase in mechanical performance. A maximum flexural strength of 5.9 MPa and a compressive strength of 26.7 MPa were observed in 28-day composites containing 0% marble–20% iron wastes. Furthermore, capillary water absorption tended to decrease with the substitution of 10% marble powder.

As the main component of energy transmission, long-distance energy transmission pipeline (LETP), whose safety problem is becoming more and more prominent with the development of the oil and gas transportation industry, is susceptible to the traffic loading, temperature loading, pressure loading and other loadings. In this paper, the mechanical characteristics of LETP under the interaction of temperature loading and pressure loading are investigated. Based on the theory of multi-field coupling, the mathematical model of fluid-solid-thermal coupling of fluid-filled pipelines under the combined effect of temperature and pressure loadings is established and verified. Meanwhile, an equivalent model is proposed to accurately calculate the stress of any pipeline segment in LETP. The results show that the coupling of temperature loading and the pressure loading is significantly affected by the end-side constraints of the pipelines. For strong end-side constraint, the coupling effect of temperature and pressure loadings has a significant effect on the calculated equivalent stress. The difference between the stress solution under coupling effect and decoupling effect is above 30 MPa. However, for weak end-side constraints, the error is within 10 MPa. The equivalent stress can be approximated by the decoupling solution instead of the coupling solution.

Carried out in the province of Tunceli since 2016, the ‘Tunceli Iron Age and Hellenistic Survey’ project is aimed at the discovery of new sites and acquisition of new data of mostly known archaeological remains that have not yet been researched thoroughly. During the final observation and documentation of the survey project’s 2021 season, two new archaeological sites were identified in the Tunceli region. The new archaeological sites in question are Masumu-Pak Fortress, which has traces of the Iron Age and the Middle Ages, and the Uzunçayır Necropolis, which should be dated to the Late Iron Age-Early Hellenistic Period. In addition, certain previously undescribed characteristics of the Gelin Odaları Necropolis, Aşağı Doluca, Rabat and Sağman Fortress settlements will be discussed in this paper. The article also includes an observation of medieval spolia artifacts used in traditional house building in the village of Til near Pertek.
- MakaleYalnız künye2022Scopus SJRQ1A novel prediction model for durability properties of concrete modified with steel fiber and Silica Fume by using Hybridized GRELM
Cemalgil, Selim; Gül, Enes; Onat, Onur; Yılmaz Aruntaş, Hüseyin
The service life performance of conventional and modified concrete subjected to harsh climatic condition environment is directly related to durability properties of concrete like abrasion, freezing and thawing cycles. These properties are critical issues that should be predicted before performing experimental test. On this basis, the basic purpose of this paper is to predict the abrasion loss, freezing and thawing properties of concrete modified with silica fume (SF) and steel fiber (SFb) by using mix design and additional properties. From this point of view, a conducted experimental study was selected as a case study. In the control concrete (CC) mixtures, Portland cement, crushed stone aggregate, and superplasticizer (SP) were used in the selected experimental study. SP in concrete mixtures was used in the amounts of 1.0%, 1.5%, and 2.0% by weight of cement, and so modified concrete was produced with and without SFb according to the target strength of C25. Furthermore, SF and SFb were used in different amounts to modify the concrete. The SF was replaced with cement in the amounts of 7.5%, 10.0%, and 15.0%. In total, 16 different mix designs were prepared with different SP and SF ratios. In addition, SFb was added to all mixtures of designed concrete at a constant amount of 65 kg/m3. Additionally, a 16-mix design was prepared with SFb. Cumulatively, 32 different mix designs were prepared for the experimental study. Tests on the fresh, hardened, and life-cycle performance properties of the concrete were conducted. As for the metaheuristic part of this study, on the basis of the available experimental data, life-cycle performance parameters of the concrete modified with SF and SFb are predicted by using single and hybrid generalized extreme learning machine methods. Eight different data sets were generated with gradually extended input data. Two different outputs were considered: abrasion resistance (AL) and freezing/thawing (FT). Particle Swarm Optimization (PSO) and Grey Wolf Optimization (GWO) algorithms were used to produce binary and ternary hybrid methods. Four different models were proposed as listed: single use of Generalized Extreme Learning Machine (GRELM), binary use of GRELM-PSO, and GRELM-GWO. Finally, PSO and GWO were hybridized and integrated into GRELM. Two quality indicators, namely Root Mean Square Error (RMSE) and correlation of determination (R2), were considered to see the performance of the prediction. The results showed that the proposed ternary prediction model composed of GRELM-PSO-GWO provided more accurate results in all sets from 74% to 91% by extending input parameters, even if complicated parameters are inserted in as an input to the data set.

İpek, Yeliz
The easy burning of cotton fabrics, which have the widest usage area among natural fibers, is a serious problem. Thus, treatment with an environmental friend flame retardant material is essential for cotton fabrics. Zinc borates are multifunctional fire retardants. They can act as smoke suppressor, flame retardant and spark suppressor. Since they are non-toxic and environmental friend materials, they are ideal flame retardants for fabric treatment. In this study, nano-sized zinc borate (ZnO·3B2O3·7H2O) was synthesized and cotton fabric was treated with zinc borate powder with a novel method. Zinc borates are slightly soluble in water. They were dissolved with aid of ammonia as zinc ammonia borate complexes and were recrystalised on the cotton fabric fibers through the evaporation of ammonia. The burning resistance of treated cotton fabric was investigated. The hardness, hydrophobicity, smoke suppression and burning resistance of untreated and treated cotton fabrics were compared. Since zinc borates have smoke suppression feature, a more slight smoke was observed and a higher rate of carbonization occurred during combustion test of treated cotton fabric compared to the untreated cotton fabric. In addition, the burning rate was reduced from 2.26 cm/s to 1.26 cm/s.
