- MakaleAçık Erişim2023Scopus SJRQ43D data integration for geo-located cave mapping based on unmanned aerial vehicle and terrestrial laser scanner data
Çömert, Resul; Özdemir, Samed; Bilgilioglu, Burhan Baha; Alemdag, Selçuk; Zeybek, Halil Ibrahim
The Akçakale cave is a significant natural and cultural heritage site in the Black Sea region of eastern Turkey. The complex geometry and difficult-to-access areas of the cave have made the use of traditional mapping methods challenging. To overcome these limitations, this study utilized TLS and UAV technology to produce highly accurate 2D and 3D data for cave management and risk assessment purposes. The TLS system was used to create a detailed 3D point cloud of the cave interior, while the UAV system generated a 3D model of the surface topography outside the cave. The two sets of data were combined in the GIS environment using a geodetic network established in the study area, providing a common geodetic reference system for both TLS and UAV data. The study found that the cave area is 13,750 m2, which is smaller than the area of 18,000 m2 that was previously estimated using conventional measurement methods. The volume and ceiling heights of the cave were calculated using the elevation models generated from TLS point cloud data. The 3D point cloud data were also used to map dripstone locations on the floor and ceiling of the cave, and the boundaries of rock blocks on the ground were precisely determined. The study identified potential risks associated with the cave, particularly the risk of rockfall in the source rock areas around the cave entrance and the southern part of the cave. The nearest building to the cave is approximately 35 meters away, and all the buildings in the area are less than 300 meters from the cave. In the event of the cave collapse, the buildings in the southern part of the cave are at risk of rockfall. This study demonstrates the effectiveness of combining data from TLS and UAV systems to generate broad and sensitive cave mapping and risk assessment data, which are critical for cave management and safety. The collected data can be used for cave stability investigations and rockfall risk assessments. This study provides a foundation for future explorations of the Akcakale cave and highlights the potential for modern surveying techniques to enhance our understanding of complex geological structures such as caves.

İncele - MakaleAçık Erişim2023Detection of COVID-19 infection from CT images using the medical photogrammetry technique
Çatal Reis, Hatice; Türk, Veysel; Kaya, Serhat
Medical data such as computed tomography (CT), magnetic resonance imaging (MRI), and Ultrasound images are used in medical photogrammetry. CT images have been used frequently in recent years for the diagnosis of COVID-19 disease, which has contagious and fatal symptoms. CT is an effective method for early detection of lung anomalies due to COVID-19 infection. Machine learning (ML) techniques can be used to detect and diagnose medical diseases. In particular, classification methods are applied for disease diagnosis and diagnosis. This study proposes traditional machine learning algorithms Random Forest, Logistic Regression, K-Nearest Neighbor and Naive Bayes, and an ensemble learning model to detect COVID-19 anomalies using CT images. According to the experimental findings, the proposed ensemble learning model produced an accuracy of 96.71%. This study can help identify the fastest and most accurate algorithm that predicts CT images with Covid-19 during the epidemic process. In addition, machine learning-based approaches can support healthcare professionals and radiologists in the diagnostic phase.

Kement, Üzeyir; Çavuşoğlu, Sinan; Çalık, Ismail; Durmaz, Yakup
This study aims to investigate the effects of environmental value and ecological worldview on eco-recreative attitudes. In recent years, human-related pollution has seriously increased. Therefore, it is critical to explain the eco-recreative attitudes of participants with an emphasis on how these attitudes support natural life. Another indicator of the significance of this study is that it explains the premises of the attitude. Environmental value in the proposed model was examined as three sub-factors: biospheric, altruistic, and egoistic. Also, an eco-recreative attitude has three sub-factors, which are affective, cognitive and behavioural. The study population consisted of individuals who participated in eco-recreation activities in Turkey. The data were collected through a questionnaire form using the convenience sampling method. The analyses were conducted using SmartPLS. The findings showed that biospheric (positive) and egoistic value (negative) had an effect on ecological worldview, while ecological worldview had a positive effect on affective, cognitive and behavioural attitude. Also, the altruistic value did not significantly affect the ecological worldview.

SUMMARY: The purpose of this study was to reveal the differences between ACTN3 genotype (RR, RX, XX) and aerobic performance [Yo-Yo IRT1 (m), VO2 max (ml/kg/min)] in professional and regional amateur league soccer players and to reveal which of these parameters was a distinctive factor in these athletes.71 professional soccer players (age: 23.66 ±4.11 years; body height: 1.79 ± 6.99 m; body weight: 76.02 ± 6.76 kg; body fat: 11.59±3.11 %) and 62 regional amateur soccer players (age: 23.63 ±3.77 years; body height: 1.81 ± 5.77 m; body weight: 76.36 ± 7.53 kg; body fat: 15.60±4.65 %) volunteered for the study. After DNA extraction from buccal epithelial cells via a commercial kit was performed for the genetic background of the athletes, Real-Time PCR was carried out for genotyping. Furthermore, Yo-Yo IRT1 test was performed to determine the aerobic performance of the soccer players. SPSS 23 (SPSS Inc., Chicago, IL, USA) package program was used for the statistical analysis of the data obtained in the tests. Shapiro-Wilk test for normality and Levene's test for homogeneity of variance were performed. Chi-Square, Independent Sample T Test and One Way ANOVA test were used in the analysis of the parameters. Statistical significance was set as p<0.05. In the study, there found no meaningful statistical significance in terms of the rs1815739 polymorphism in the ACTN3 gene between the groups (p>0.05); however, there was a statistical significance in favor of professional soccer players in terms of aerobic parameters (p<0.05). Consequently, it can be said that aerobic performance is the distinguishing factor, not the ACTN3 gene, in soccer players.

Cavusoglu, Ibrahim; Fall, Mamadou
This paper presents the effects of a full-range water-reducing (FRWR) admixture on the key engineering properties of cemented paste backfill (CPB). CPB samples with a certain slump are prepared with 4.5% cement by mass of the tailings and different dosages of an FRWR admixture (superplasticizer contents of 1%, 3%, and 5%) to evaluate their water demand during hydration, rheological properties, self-desiccation ability, and microstructural and mechanical properties. Moreover, cement paste samples with a high water-to-cement ratio (w/c = 2) which are used to model the cement matrix of the CPB are prepared for x-ray diffraction (XRD) scanning and thermal analyses (TAns). The results show that the addition of an FRWR admixture to the studied CPB can reduce its water demand by up to 23% and significantly increase its strength from 1.0 MPa to 2.38 MPa (by approximately 2.4 times) at 28 days. The pore volume of the CPB samples is also significantly reduced from 27.17 to 18.27% due to the capability of the FRWR admixture to reduce water demand. Also, the addition of an FRWR admixture to the CPB results in a substantial decrease (up to 83%) of its yield stress, thereby improving its flowability. The CPB samples with an FRWR admixture are found to have a higher negative pore water pressure, i.e., higher self-desiccation, than the CPB sample without an FRWR admixture. The microstructural analysis also shows that the FRWR admixture has an increasing effect on the hydration products in the CPB mixture.

Sipahi, Ferkan; Sadiklar, M. Burhan; Gücer, Mehmet Ali; Aydin, Ali; Kara, Rasim Taylan
Iron (Fe)-skarn mineralizations (Çambaşı, Dereli, Eğrikar, Karadağ, Kopuz, Sekü, Donguldere, Arnastal, Özdil, Ögene, İkizdere, Ovit Dağı, Kartiba, etc.) in the eastern part of the Pontides (NE Türkiye) are accommodated in the Pontide paleomagmatic arc and the eastern part of the Pontides Metallogenic Belt containing numerous various deposits. Fe-skarn mineralization around the Arnastal Plateau (Gümüşhane-Türkiye) is fragmentary in this area, which is covered with plants (grasses, flowers, etc.). Thus, it was attempted to describe the subsurface structures and Fe mineralization using an interpretation of the available geological and existing magnetic data in this area. Granitoid and volcano-sedimentary series (Upper Cretaceous) outcrop in the study area. These volcanosedimentary series consist of limestone, sandy limestone, marl, andesite, quartz andesite, basalt, and their equivalent pyroclastics. They include a thin layer of the red limestone (Upper Cretaceous) and olistolith recrystallized limestones (Jurassic-Lower Cretaceous). Zigana granitoid, intruding into all of these rocks, is high-K calc-alkaline and metaluminous and is classified as quartz monzonite, monzogranite, granite, and syenogranite as a result of its modal composition. Contact pyrometasomatic mineralization occurs in between the limestone and granitoids in the Arnastal Plateau. In addition to petrographic and mineralogical studies, magnetic methods were applied to an area of approximately 10 km2 to find any covered Fe deposits. Magnetic susceptibility values measured on the outcropped rocks ranged from 1 to 34 (10–7 SI) for limestone, 78 to 3750 (10–7 SI) for basalt, and 105 to 3946 (10–7 SI) for granitoids. It is considered that these ranges express the alteration (physical or chemical) of the rocks, their homogeneity, and the lack or presence of Fe minerals. The magnetic survey was conducted along a study area measuring 12,075 m long with 25 and/or 50 m station spacing. Processing of the magnetic data revealed the presence of eight buried Fe ores that could represent either massive or disseminated mineralization between the Sarıtaş and Kurtdere plateaus. Magnetite ore bodies may be present from the surface to a depth of approximately 15–25 m inside the limestone. In addition to the identification of new magnetite ore mineralization or bodies, a new geological map was designed by determining probable formation boundaries with this magnetic survey.

This study, which aims to determine the e-learning attitudes of talented teacher candidates following the earthquakes in Kahramanmaraş and Hatay and to compare them according to some variables, was designed with a cross-sectional-survey model, one of the quantitative research methods. The research sample was comprised of 826 pre-service teachers from the fields of Physical Education and Sports, Music Education, and Visual Arts during the spring semester of 2022-2023. Data for the study were collected using the Test of E-Learning Related Attitudes Scale, with data collection conducted through Google Forms. Data analysis was used to SPSS program. In terms of the academic department variable, it was concluded that pre-service teachers specializing in Physical Education and Sports, Music Education, and Visual Arts demonstrated similar levels of E-learning attitudes, and no statistically significant differences were observed among them (p<0.05). Furthermore, in the context of education and instructional activities being carried out through online learning methods, it was determined that the choice of and utilization of computers and mobile devices as learning tools resulted in similar overall E-learning attitudes (p<0.05). Nevertheless, those who favored mobile devices demonstrated a statistically higher level of inclination toward technology use and perceived usefulness, while those who used computers reported statistically higher levels of satisfaction and motivation in their E-learning attitudes (p<0.05). According to the research results, it was observed that the E-learning attitudes of pre-service teachers following the Kahramanmaraş and Hatay earthquakes were at a moderate level, with satisfaction in online learning registering as the least favorable aspect of E-learning attitude.

The primary objective of this research is to assess the level of team cohesiveness and role ambiguity among students who participate in university team sports, and examine them based on pre-determined variables. The selection of participants was conducted through a convenient sampling approach. The study employed the cross-sectional scanning method and comprised a sample of 238 participants, consisting of 88 females (37%) and 150 males (63%), who are engaged in team sports at Gümüşhane University during the 2022-2023 academic year. A Personal Information Form, Team Cohesion Scale and Role Ambiguity Scale were utilised to gather data in this study. Data was then analysed using T-tests, ANAVO and correlation tests. Analysis results indicate that university students who participate in team sports demonstrate above average team unity, whilst exhibiting below average role ambiguity. Men were found to have better scores in the team unity and group attractiveness task dimensions, based on gender. In contrast, students studying in departments other than physical education and sports schools reported higher role ambiguity. It has been noted that university students who have played on the same sports team for 1-5 years encounter greater role ambiguity compared to those who have had longer experience. Playing different sports and the number of years spent playing sports did not impact participants' team unity or role ambiguity. An additional noteworthy finding is the negative significant connection between role ambiguity and team commitment. Copyright q 2023, SEPM (Society for Sedimentary Geology) 0883-1351/23/038-353.

Şenaslan, Fatih; Taşdemir, Muharrem; Çelik, Ayhan; Bozkurt, Yusuf Burak
β-Titanium alloys have become increasingly popular as biomaterials because of their low modulus of elasticity and superior corrosion properties in recent years. β-titanium alloy containing niobium is also a biocompatible and non-toxic material. Among β-Ti alloys, Ti45Nb is one of the most remarkable alloys for its superior properties as a biomaterial. This alloy has superior properties due to low elasticity modulus and non-toxic elements, but its surface properties are inadequate for biomaterial applications. Therefore, various surface treatments are applied to improve the surface properties of these alloys. In this study, an oxide film layer was formed on the Ti45Nb surface under different potential conditions by the anodizing method. The effects of these factors on friction, wear, and contact angle measurements were investigated. The structural properties of the oxide film coated samples were analyzed with XRD and their surfaces and cross-sectional images were observed by SEM. Also, the surface roughness and nanoindentation tests were performed. In this regard, it was determined that oxide film thickness, surface roughness and hardness increased with the increase of anodization potential. The contact angle of the samples decreased with the increase in the anodization potential and the surface tension of the materials increased. The highest nanohardness of about 4.19 GPa was obtained from 150 TA samples. The elasticity modulus of the untreated sample was about 63 GPa, while the anodized samples ranged from an average of 31 to 83 GPa. The wear results revealed that the anodization process improved the wear resistance of the Ti45Nb alloy. As a result, the sample anodized at 200 V for 30 min exhibited optimum surface roughness, morphology and high wear resistance.

Özdemir, Samed; Yavuzdoğan, Ahmet; Bilgilioğlu, Burhan Baha; Akbulut, Zeynep
Decentralized solar PhotoVoltaic (PV) is one of the most promising energy sources for cities and individuals pursuing energy self-sufficiency. Especially, the already available rooftop surfaces are a major contributor to push for rooftop mounted PV systems. However, accurate PV potential estimation of individual buildings is still a challenging task since many parameters must be considered such as meteorological factors, panel technology, geographical location, available roof surface area, surface azimuth and tilt angle. In this study, we created an efficient approach that can be used for roof surface's PV potential estimation based on point cloud data and capable of processing various scales from single building to city scale. In the proposed approach, each roof surface's features were utilized for PV potential estimation by employing the PVGIS database. PV potential estimation was carried out on daily, monthly, and annual periods to provide a better estimation. Also, we developed a flexible and easy to use open-source plugin based on the QGIS software for rooftop mounted PV potential estimation capable of estimating every roof surface's PV potential. The method was tested on 80 buildings selected from ROOFN3D dataset. The proposed approach achieved an overall accuracy of 84% and an F1 score of 0.92.

Puerarin, which was used as a natural isoflavone in this study, was obtained from the Kudzu plant. The inhibitory effect of puerarin on acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes was investigated. The IC50 values of AChE (177.73 nM) and BChE (315.07 nM) were determined. The binding mechanism of puerarin, which has a high inhibitory effect on the active site of the enzyme, was demonstrated by the molecular docking method. The antioxidant activity was evaluated for the same molecule. For this purpose, Fe3+-Fe2+ reducing capacity, ABTS radical scavenging activity, CUPRAC method, DPPH⋅ scavenging activity and DMPD radical scavenging method were used. The percentage (%) inhibition amount of puerarin molecule was calculated as 99.33 % for ABTS radical scavenging activity, which is the more preferred method for natural products. The absorbtion value of iron reduction of Puerarin was 0.122±0.010, and the value of copper reduction was 0.633±0.026. Our research efforts include uncovering the potent antioxidant potential of puerarin and, simultaneously, a comparative study of tacrine, primarily emphasizing its inhibitory effects against AChE and BChE enzymes. The puerarin is expected to be a guide for drug discovery against many problems, especially oxidative cell damage in Alzheimer's disease, mitochondrial dysfunction (MD), cancer, and cardiovascular diseases.

The Gram-negative bacteria were isolated from various samples and antibiotic susceptibility testing were performed. The strains were screened by PCR for class 1 integron, virulence and antibiotic resistance genes. blaOXA-23 and blaOXA-51 genes positive samples were cloned into the pGEM-T vector and the plasmids were sent for DNA sequence analysis. The isolates were showed resistance to quinolone, cephalosporin, aminoglycoside, carbapenem and penicillin group antibiotics. Virulence factor genes were identified in 121 strain. The most common virulence gene was determined to be aer (29.78%), followed by sfa (28.19%), afa (27.12%), cnf (21.27%), pap (12.76%) and hly (12.76%). In addition, 34 different virulence patterns were observed. Plasmid-mediated quinolone resistance genes were detected 15 of67 quinolone-resistant isolates. Among carbapenem resistant strains, blaOXA-23 gene was detected in 16 and blaOXA-51 gene in 19 isolates. The strains producing OXA-23 and OXA-51 were Klebsiella oxytoca, Acinetobacter baumannii, E.coli and P.mirabilis. In this study, clinical isolate K. oxytoca carrying both blaOXA-23 and blaOXA-51 genes were identified first time from Türkiye. A high predominance (88.82%) of class 1 integron was detected. In addition, determined that 46.27% of the isolates had the ability to form biofilms. In conclusion since the limited treatment options of antibiotic-resistant Gram-negative pathogens that cause serious infections are an important problem in terms of public health it is important to investigate antibiotic resistance, virulence factor genes and biofilm formation in these pathogens.

Doğru, Fikret; Maden, Nafiz
The Black Sea Basin (BSB) consisting of Eastern Black Sea (EBS) and Western Black Sea (WBS) basins which separated by the Mid Black Sea High (MBSH) is formed by the collision of Eurasia and Arabian-African Plates. Petroleum and gas hydrate contents of the BSB have been discussed by using different geological and geophysical research. In this study, the gravity gradient tensor and invariant data based on the Bouguer gravity anomaly of the EBS basin were evaluated to define the hydrocarbon reservoirs. Afterwards, Euler deconvolution technique is applied to the invariant to reveal the depth of subsurface bodies. Furthermore, the significant invariant anomalies are compared with known oil seepage and petroleum wells. The depth values of oil trace closest to the known Sürmene and Hopa drill holes were computed as 4809 m, and 4455 m according to the structural index values of SI = 2.

Külekçi, G.; Çullu, M.; Yilmaz, A.O.
Abstract: This study examines the usability of concrete wastes generated from buildings demolished for various reasons in shotcrete. The strength properties of shotcrete produced from recycled aggregates (RA), cylinder specimen and plate specimen were tested. it was observed that as the ratio of RA used instead of natural aggregate increases, the strength of the cylinder specimen decreases, ultrasonic pulse velocity increases. The toughness value has increased in the concrete samples prepared by replacing the natural aggregate with 50% or more RA. It was observed that the fiber amount and load carrying capacity were proportional in fiber reinforced plates prepared using RA. As a result, it has been observed that the interaction of RA with fiber is positive and it can be used in shotcrete. It has been revealed that RA can contribute to the reduction of environmental pollution caused by construction and wreckage wastes and can be presented as an alternative to natural aggregate.

Eker, Çiğdem Saydam; Arı, Uğur Volkan
Samples from late Jurassic–early Cretaceous age limestones in five different areas in the Gümüşhane region (NE-Türkiye), were studied using TOC/Rock–Eval, and some trace elements analysis, to evaluate their organic material source, type, thermal maturity, and paleo-environment conditions. The studied carbonate rocks are characterized by 90 m thick in the Bağlarbaşı section, 420 m in the Gülaçar, 584 m in the Ünlüpınar, 375 m in the Mescitli, and 272 m in the Yuvacık. The carbonate rocks are generally represented by, from bottom to top, dolomite, oolitic, sparitic, sandy, micritic, clayey, and bituminous limestones. Average total organic carbon (TOC) values are 0.14, 0.16, 0.20, 0.12, and 0.20% in the Bağlarbaşı, Gülaçar, Ünlüpınar, Mescitli, and Yuvacık sections, respectively. Organic material in the limestones consists of Type II-III kerogen, indicating that a mixture of terrigenous higher plants–marine aquatic organisms was the main source. Average Tmax values and Tmax-based vitrinite reflectance values (Ro %) are calculated as 435 and 0.67, 444 and 0.83, 431 and 0.60, 442 and 0.79, and 437 °C and 0.70 in the Bağlarbaşı, Gülaçar, Ünlüpınar, Mescitli, and Yuvacık sections, respectively, indicating that the samples have generally reached thermal maturity. The limestones in the Gülaçar, Mescitli, and Yuvacık areas are probably well-drained rocks that were extracted and originated hydrocarbon efficiently from the limestone fractures. In general, a non-marine–sometimes marine deposition environment for the carbonates is indicated by total sulfur values. V/Ni and Sr/Ba ratios indicate a stratified water column with high–low salinity and anoxic–oxic bottom water circumstances and accordingly a transitional sedimentation environment.

Aslan, Ramazan; Köçer, Musab Süleyman; Mizrak, And Sefa
Anthropogenic climate change (ACC) is considered to be one of the biggest threats to humanity in this century, with severe direct or indirect impacts on people’s lives. Such a significant threat causes serious concern, which can motivate low-level proenvironmental behavior and lead to serious health problems at high levels. Therefore, determining the level of this concern is crucial. Outdoor recreation participants, who are constantly in contact with nature, can closely witness the effects of ACC due to these interactions. Therefore, evaluating their ACC worry is essential. In this study, the aim was to determine the ACC worry levels of outdoor recreation participants. The research data were collected through an online survey from a sample reached through convenience sampling method throughout Türkiye. The data were analyzed using analysis of moment structures (AMOS) and Statistical Package for the Social Sciences (SPSS) software. The relationship between independent variables and ACC concern was revealed through ordinal logistic regression. The research found that the participants had a high level of concern about ACC, with a score of 3.50. It was also determined that this level of concern was influenced by variables such as the type of outdoor recreation, the duration of participation in outdoor recreation, and exposure to the effects of ACC. Considering that ACC can motivate proenvironmental behaviors, the research suggests that outdoor recreational participants with high levels of concern about ACC should not be ignored in the adaptation process.

The proportions and constituents of the essential oils of flowers and leaves of Primula veris subsp. columnae were determined, and the antioxidant and the antimicrobial (antibacterial and antifungal) properties of their methanol extracts were investigated. Percentage ratios and main components of the Primula veris subsp. columnae plant, which grows naturally, were detected by extracting flower and leaf volatile oils. The components of the volatile oil were identified with Gas Chromatography Mass Detector-Flame Ionization Detector (GC-MS/FID). A total of 62 compounds were identified in flower volatile oil, and methyl 4methoxysalicylate (37.1%) was determined as the main compound. While defining the structure of 50 compounds in leaf essential oil, linoleic acid (40.1%) was established as the main compound. As the result of the extraction of flowers and leaves with methanol, the extractive substance was obtained as 34.5% in flowers and as 28.8% in leaves. Methanol extraction and the antioxidant properties of the Primula veris subsp. columnae plant were quite high. In the antifungal and antibacterial activity test conducted on the volatile oils and methanol extracts of flowers and leaves of the Primula veris subsp. columnae species, only flower volatile oil showed weak inhibition properties.

The use of mobile applications is widespread in patient monitoring or education today. This study aims to describe the design and development process of a mobile app that supports patient self-care after breast cancer surgery. We used the ADDIE model to develop and test the mobile app. ADDIE (Analysis, Design, Development, Implementation, Evaluation) is a systematic approach based on a standard instructional design model for creating training materials. The model consists of five phases, each with its own set of steps. Once the steps within each phase are completed, the model progresses to the next phase, ultimately resulting in a “usable” product. Different team collaborations were established within each phase, and support was obtained from multiple experts during the design process. Thanks to this model, the information that patients need was transformed into a technological product. This article, which explains the stages of the product design process for mobile applications, provides information that may be helpful to researchers working on similar products.

This paper introduces an evaluation of the hydrodynamic performance of the flow in the screens used on the physical unit operations in a selected full-scale wastewater treatment plant (WWTP) based on Computational Fluid Dynamics (CFD) simulations. The numerical study was carried out with the ANSYS Fluent, CFD software by using the three-dimensional (3 D), steady, incompressible flow based on the Reynolds-Average Navier-Stokes equations with three different turbulence modeling. The hydrodynamic behavior of the screening facility, combined with head pond-upstream channel-bar screens was evaluated under different conditions of the mass flow rate and velocity fields. Also, the numerical study was validated against the experimental study, which implemented in-situ measurements by Acoustic Doppler Velocimeter (ADV), and consistent results were obtained between the numerical and experimental study. Interestingly, while the Realizable (real) k-ε turbulence model with the relative error of 9.31% gave the best predicting results in the head pond, the renormalization group (RNG) k-ɛ turbulence model with the relative error of 9.05% gave the best predicting results in the upstream channel and through bar screens. As a result of the experimental measurements and CFD analyses carried out in the full-scale WWTP, the function of the screening facility was found to be incomplete. Moreover, a hydraulically improved new geometry was presented to operate the existing WWTP efficiently.

Tahini, as a low moisture food product, is linked to several outbreaks of Salmonella recently even though a high temperature roasting (of sesame seeds) through its production is involved. Therefore, a final decontamination approach might be required for safety. Considering its higher oil content and lower thermophysical properties, conventional approaches are not easy to apply while preserving the quality attributes. Therefore, microwave heating was used for decontamination purpose. For this purpose, a computational mathematical model was developed first to determine the temperature distribution of tahini during microwave heating, and microbial inactivation studies for Salmonella enteritidis (ATCC 13076) were carried out. Changes in color and peroxide values were evaluated, and the experimentally validated model was further used to design an industrial process to achieve a 5-log cycle reduction as an efficient decontamination processing. The target temperature over 80 °C within the sample was demonstrated to achieve such a process, and industrial scale process conditions were presented for 262 kg/h process capacity.
