Ömer-Gecek (Afyonkarahisar) jeotermal sahası rezervuar kayaçlarının mineropetrografik ve jeokimyasal özellikleri

The most important elements of the geothermal system are fluid, reservoir-cover rock, heat source, and fault lines. In geothermal basins, it is necessary to have a reservoir rock of sufficient thickness with high porosity and permeability. This study aims to determine the mineralogic-petrographic and geochemical features of the marbles, which are the reservoir rocks of Omer-Gecek geothermal region. In this scope, the samples taken from both the outcrops and the geothermal drillings made in the region were investigated and the possible effects of water-rock interaction were determined. There are low and medium temperature (45-128ºC) fluids produced from Omer-Gecek region, the most important geothermal field in Afyonkarahisar (Western Turkey). Afyon metamorphics, which are composed of Bayramgazi schists and Oyuklu Tepe marbles, are the basement rocks of the study area and the marble lenses/bands form the reservoir rock. As a result of the analyses, it has been determined that the samples are mainly composed of calcite and dolomite minerals, and these minerals are accompanied by quartz and mica minerals with secondary minerals and kaolinite minerals as alteration minerals. The granoblastic textured outcrop marble samples gained breccia texture due to alteration and secondary manganese and iron-rich solutions were deposited into the pores and micro-cracks. According to the geochemical analysis results, while the CaO is the most important component in outcrop samples, it is significantly depleted in drilling samples, while MgO, Al2O3, and SiO2 levels are enriched.Jeotermal sistemin en önemli elemanlarını akışkan, rezervuar kayaç, örtü-ısıtıcı kayaç ve fay hatları oluşturmaktadır. Jeotermal havzalarda her şeyden önce yüksek porozite ve permeabiliteye sahip olan yeterli kalınlıkta rezervuar kayacın bulunması zorunludur. Bu çalışmanın amacı Ömer-Gecek jeotermal bölgesinin rezervuar kayacı olan mermerlerin mineralojik-petrografik ve jeokimyasal özelliklerinin belirlenmesidir. Bu kapsamda hem mostra yüzeylerinden, hem de bölgede yapılmış olan jeotermal sondajlardan alınan kırıntı numuneler üzerinde incelemeler yapılarak, su-kayaç etkileşiminin muhtemel etkileri belirlenmiştir. Afyonkarahisar ilindeki en önemli jeotermal saha olan Ömer-Gecek bölgesinden düşük ve orta sıcaklıkta (45-128ºC) akışkan üretilmektedir. Bayramgazi şistleri ve Oyuklu Tepe mermerlerinden oluşan Afyon metamorfikleri inceleme alanının temel kayaçları olmakla birlikte, bu istif içerisinde yer alan mermer mercek ve bantları akışkanların ana rezervuarını oluşturmaktadır. Yaptırılan analizler sonucunda örneklerin başlıca kalsit ve dolomit minerallerinden oluştuğu, bu minerallere tali oranda kuvars ve mika mineralleri ile alterasyon minerali olarak kaolinit mineralinin eşlik ettiği görülmektedir. Makroskobik olarak şekerimsi doku gösteren mermerler alterasyonun etkisiyle breşik yapı kazanmış ve sekonder mangan ve demir bakımından zengin eriyikler kayaç içindeki boşluk ve mikro çatlaklara yerleşmiştir. Jeokimyasal sonuçlara göre, mostra örneklerinde CaO kimyasal bileşimindeki en önemli bileşen olarak göze çarpmakta iken kırıntı örneklerde CaO önemli derecede azalmakta ve MgO, Al2O3 ve SiO2 miktarlarında artış gözlenmektedir

Relieving the burden of intensive labeling for stress monitoring in the wild by using semi-supervised learning

Stress, a natural process affecting individuals' wellbeing, has a profound impact on overall quality of life. Researchers from diverse fields employ various technologies and methodologies to investigate it and alleviate the negative effects of this phenomenon. Wearable devices, such as smart bands, capture physiological data, including heart rate variability, motions, and electrodermal activity, enabling stress level monitoring through machine learning models. However, labeling data for model accuracy assessment poses a significant challenge in stress-related research due to incomplete or inaccurate labels provided by individuals in their daily lives. To address this labeling predicament, our study proposes implementing Semi-Supervised Learning (SSL) models. Through comparisons with deep learning-based supervised models and clustering-based unsupervised models, we evaluate the performance of our SSL models. Our experiments show that our SSL models achieve 77% accuracy with a classifier trained on an augmented dataset prepared using the label propagation (LP) algorithm. Additionally, our deep autoencoder network achieves 76% accuracy. These results highlight the superiority of SSL models over unsupervised learning techniques and their comparable performance to supervised learning models, even with limited labeled data. By relieving the burden of labeling in daily life stress recognition, our study advances stress-related research, recognizing stress as a natural process rather than a disease. This facilitates the development of more efficient and accurate stress monitoring methods in the wild

Large-scale orientational order in bacterial colonies during inward growth

During colony growth, complex interactions regulate the bacterial orientation, leading to the formation of large-scale ordered structures, including topological defects and microdomains. These structures may benefit bacterial strains, providing invasive advantages during colonization. Active matter dynamics of growing colonies drives the emergence of these ordered structures. However, additional biomechanical factors also play a significant role during this process. Here we show that the velocity profile of growing colonies creates strong radial orientation during inward growth when crowded populations invade a closed area. During this process, growth geometry sets virtual confinement and dictates the velocity profile. Herein, flow-induced alignment and torque balance on the rod-shaped bacteria significantly differed, resulting in new stable orientational equilibrium in the radial direction. Our analysis revealed that the dynamics of these orientational defects depend on bacterial length and can promote the survival of the longest bacteria around localized nutritional hot spots. The present results indicate a new mechanism underlying structural order and provide mechanistic insights into the dynamics of bacterial growth on complex surfaces

Intraosseous Mucoepidermoid Carcinoma of the Jaw: Report of Three Cases

Mucoepidermoid carcinoma (MEC) is the most common malignant tumor of the salivary glands and is seen most commonly in the parotid gland. Intraosseous MECs can be rarely seen and is mostly detected in the posterior part of the mandible. This condition can be acknowledged as an entity different from salivary gland MECs. In this case series, we delineated three patients of intraosseous MEC, two mandible tumors and one maxillary tumor and discussed the diagnostic characteristics and treatment methods of this rare entity

Comparison of radon concentrations in soil gas and indoor environment of Afyonkarahisar province

It is well known that radon is the main source of natural radiation exposure to the population. Indoor radon concentrations in an area are affected by ascending radon migration following the convection of groundwater and soil gas along fractures and faults in the bedrock sediments. There are various studies showing that positive radon anomalies in the soil gas are found to coincide with the locations of houses showing the highest concentrations. Moreover, soil gas radon levels and soil permeability are important factors in determining the radon potential of an area, because high permeability enables the increased migration of radon from the soil into houses. Since radon in homes originates mainly from soil gas radon, it is of public interest to study the correlation between soil gas radon and indoor radon in different geographic locations. In the present work, a correlation study was carried in conjunction with radon concentrations in soil gas and indoor environment of Afyonkarahisar Province. The provincial center was assumed to be divided into four regions according to the rock types and tectonic structure to show also the geological structure effect on radon concentrations. The indoor radon concentrations were measured in 74 dwellings using CR-39 passive nuclear track detectors, and the radon concentrations in soil gas were determined in 243 drilled holes using AlphaGUARD detector. The correlation coefficient of 0.97 was obtained between radon concentrations in soil gas and indoor environment of Afyonkarahisar Province.Turkish Atomic Energy Authority Afyon Kocatepe University Science Research Projects Coordination Uni

Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study

PURPOSEThe clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.METHODSThis retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson’s chi-squared test, the Fisher–Freeman–Halton test, and Fisher’s exact test were used for the statistical analyses.RESULTSThe overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSIONADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision
