Impact of Piping Erosion Process on the Temporal–Spatial Mechanisms of Soil
Authors: Xiao Qiong
Published: September 2022

Earthen dams with greater fines are more susceptible to failure from the piping. This study employed the coupled computational fluid dynamics (CFD)-discrete element method (DEM) to investigate the impact of the piping erosion process. Results displayed that increasing the fine contents would reduce the particle velocity and drag force for enhancing the erosion resistance. Piping would reduce the stability of the structure at different positions of the sample with various fine contents. The representative volume elements (RVE) were selected to observe the local geometry and material behavior as the erosion progressed. Severe water flows significantly reduced the peak shear strength of the eroded soils for the interactive-underfilled soil, particularly for the downstream side. However, the interactive-overfilled specimen reduced the peak shear strength on the upstream side. Results indicated that the proposed weighted clustering coefficient is a better index to capture the shear strength of the eroded soil matrix, with a high magnitude corresponding to a high peak shear strength. Different local material behavior may lead to differential settlements and associated catastrophic consequences during the piping erosion process, which should draw special attention.
Implications of Bacterial Adaptation to Phenol Degradation under Suboptimal Culture Conditions Involving Stenotrophomonas maltophilia KB2 and Pseudomonas moorei KB4
Authors: Nowak Agnieszka , Wasilkowski Daniel , Mrozik Agnieszka
Published: September 2022

Despite the well-described abundance of phenol-degrading bacteria, knowledge concerning their degradation abilities under suboptimal conditions is still very limited and needs to be expanded. Therefore, this work aimed to study the growth and degradation potential of Stenotrophomonas maltophilia KB2 and Pseudomonas moorei KB4 strains toward phenol under suboptimal temperatures, pH, and salinity in connection with the activity of catechol dioxygenases, fatty acid profiling, and membrane permeability. The methodology used included: batch culture of bacteria in minimal medium supplemented with phenol (300 mg/L), isolating and measuring the activity of catechol 1,2- and 2,3-dioxygenases, calculating kinetic parameters, chromatographic analysis of fatty acid methyl esters (FAMEs) and determining the membrane permeability. It was established that the time of phenol utilisation by both strains under high temperatures (39 and 40 °C) proceeded 10 h; however, at the lowest temperature (10 °C), it was extended to 72 h. P. moorei KB4 was more sensitive to pH (6.5 and 8.5) than S. maltophilia KB2 and degraded phenol 5–6 h longer. Salinity also influenced the time of phenol removal. S. maltophilia KB2 degraded phenol in the presence of 2.5% NaCl within 28 h, while P. moorei KB4 during 72 h. The ability of bacteria to degrade phenol in suboptimal conditions was coupled with a relatively high activity of catechol 1,2- and/or 2,3-dioxygenases. FAME profiling and membrane permeability measurements indicated crucial alterations in bacterial membrane properties during phenol degradation leading predominantly to an increase in fatty acid saturation and membrane permeability. The obtained results offer hope for the potential use of both strains in environmental microbiology and biotechnology applications.

Published: September 2022

The water and gas permeability of pervious concrete play essential roles in rainwater infiltration and plant root respiration. In this study, the gas and water permeability of pervious concrete samples were measured and compared. The water permeability was tested using the constant water head method and several water heads were measured for inspection, in which the permeability varied with the application of the pressure gradient. The permeability of gas was measured using a new simple gas permeameter, which was specially manufactured for measuring the gas permeability of pervious concrete under a stable pressure difference. A series of different gas pressure gradients was applied to test whether the gas permeability was a function of the applied pressure. Both the gas and water permeability of pervious concrete were found to decrease with an increased applied pressure gradient, which did not conform to the Klinkenberg effect (gas slippage effect). When comparing the gas permeability and water permeability of pervious concrete, we found that the water permeability was 4–5 times larger than the gas permeability.
The Use of GAMLSS Framework for a Non-Stationary Frequency Analysis of Annual Runoff Data over a Mediterranean Area
Authors: Scala Pietro , Cipolla Giuseppe , Treppiedi Dario , Noto Leonardo Valerio
Published: September 2022

Climate change affects all the components of the hydrological cycle. Starting from precipitation distribution, climate alterations have direct effects on both surface water and groundwater in terms of their quantity and quality. These effects lead to modifications in water availability for agriculture, ecology and other social uses. Change in rainfall patterns also affects the runoff of natural rivers. For this reason, studying runoff data according to classical hydrological approaches, i.e., statistical inference methods that exploit stationary probability distributions, might result in missing important information relevant to climate change. From this point of view, a new approach has to be found in the study of this type of data that allows for non-stationary analysis. In this study, the statistical framework known as Generalized Additive Models for Location, Scale and Shape (GAMLSS), which can be used to carry out non-stationary statistical analyses, was applied in a non-stationary frequency analysis of runoff data collected by four gauges widely distributed across Sicily (Italy) in the period 1916–1998. A classical stationary frequency analysis of these runoff data was followed by a different non-stationary frequency analysis; while the first was made using annual rainfall as a covariate, with the aim of understanding how certain statistical parameters of runoff distribution vary with changes in rainfall, the second derived information about the temporal variability of runoff frequencies by considering time as a covariate. A comparison between stationary and non-stationary approaches was carried out using the Akaike information criterion as a performance metric. After analyzing four different probability distributions, the non-stationary model with annual rainfall as a covariate was found to be the best among all those examined, and the three-parameter lognormal the most frequently preferred distribution.
How Robust Is a Multi-Model Ensemble Mean of Conceptual Hydrological Models to Climate Change?
Authors: Kimizuka Takayuki , Sawada Yohei
Published: September 2022

It is a grand challenge to realize robust rainfall-runoff prediction for a changing climate through conceptual hydrological models. Although multi-model ensemble (MME) is considered useful in improving the robustness of hydrological prediction, it has yet to be thoroughly evaluated. We evaluated the robustness of MME by 44 conceptual hydrological models in 582 river basins. We found that MME was more accurate and robust than each individual model alone. Although the performance of MME degrades in the validation period, the extent of degradation is smaller for MME than for individual models, especially when the climatology of river discharge in the validation period is greatly different from that in the calibration period. This implies the robustness of MME to climate change. It was found to be difficult to quantify the robustness of MME when the number of basins and models is small, which implies the importance of the large number of models and watersheds to evaluate the robustness and uncertainty in hydrological prediction.

Published: September 2022

In order to study the energy and cavitation performance of a high-ratio axial flow pump, the SST k-ω turbulence model and ZGB cavitation model were used to numerically calculate the energy and cavitation performance of a high-ratio axial flow pump, and a model test analysis was carried out. The study concluded that the errors in the numerical calculation of head, efficiency, and critical cavitation margin are within 0.2 m, about 3% and 5%, respectively, and the numerical calculation results are reliable. For the flow conditions of Q = 411 L/s, 380 L/s, 348 L/s, and 234 L/s, the numerically calculated critical cavitation margins are 7.1 m, 5.7 m, 4.6 m, and 9.5 m, respectively, and the experimental critical cavitation margins are 7.5 m, 4.9 m, 4.6 m, and 9.5 m, respectively, with errors of −0.4 m, 0.8 m, 0.0 m, and 0.0 m, in that order; numerical calculations and test results trend the same, with small errors. Under the same inlet pressure, as the flow rate decreases, the vacuole first appears at the head of the blade pressure surface under the large flow rate condition (Q = 411 L/s), and the vacuole appears at the head of the blade suction surface under the small flow rate condition (Q = 234 L/s). As the inlet pressure decreases (pin = 11 × 104–4 × 104 Pa), the vacuole gradually increases under the same flow rate and the cavitation degree increases. The research results of this paper can provide a reference for the study of the energy and cavitation mechanism of the same type of axial flow pump.

Authors: Kassymbekov Zhuzbay , Kuldeev Yerzhan , Kassymbekov Galymzhan
Published: September 2022

The intake of natural water or waste water from a depth exceeding the suction height of centrifugal pumps is mainly carried out due to additional water supply at the suction of the pump. However, this process becomes more complicated if it is necessary to purify water from mechanical impurities. The purpose of the presented work is to consider this issue based on the development and study of the parameters of an ejector water intake treatment plant equipped with a pressure-vacuum hydrocyclone. The main contribution of the ongoing research is the establishment of the technological parameters of the installation, and their features in the pressure-vacuum mode of operation, in contrast to the known pressure and vacuum hydrocyclones separately. In terms of methodology, the main parameters of the developed installation were established during the testing of its prototype on a specially built stand using well-known regulatory guidelines in the hydraulic research system. As a result of the study, the nature of the change in pressure inside a cylindrical–conical hydrocyclone, with established design dimensions and the patterns of formation of vacuum and pressure-vacuum modes depending on the initial parameters, was revealed. The data obtained to determine the effect of technological parameters of ejection and the characteristics of the supplied water with impurities on the operating mode of the hydrocyclone confirm the efficiency of water intake and purification. A rational mode of joint operation of the elements of a closed system is achieved at the maximum value of the installation efficiency and ensuring low specific energy consumption per 1 m3 of treated water.
A Multidisciplinary Approach to Posidonia oceanica Detritus Management (Port of Sperlonga, Italy): A Story of Turning a Problem into a Resource

Published: September 2022

Ports are affected by a high rate of sedimentation that requires frequent dredging of the seabed to restore bathymetric levels. In some cases, the sediments consist of a large amount of leaves of phanerogams (e.g., P. oceanica) that must be treated differently from what is required by the Italian law on sediments (Ministerial Decree No. 173/2016), since soils cannot be treated either as sediment or as waste. About one meter of the sediment cores collected in the Port of Sperlonga consisted of organic waste derived from a different stage of seagrass decomposition. To optimize the management, the decomposed organic detritus was characterized from physical-chemical (content of nutrient and pollutants), ecotoxicological and mechanical (microtensile, microscopic structure) points of view, to define different management solutions for the final disposal. The results of this study describe the characteristics of this type of organic detritus, highly present in Mediterranean coastal ecosystems, and allow a better definition of different possible solutions to valorize this resource instead of disposing it in an organic waste landfill. The search for environmentally friendly options for waste management is of particular interest in terms of the green economy, and the reduction of CO2 emissions as an indirect effect obtained by improving waste recycling.

Published: September 2022

In regions with a temperate climate, a well-maintained grass sod on a clay layer is considered a reliable protection for dams and dikes. In the Living Lab Hedwige-Prosperpolder, on the left bank of the Scheldt river straddling the border between Belgium and the Netherlands, a series of 27 overflow tests with a purpose-built overflow generator has been executed to determine the strength of the protective layer against erosion at various conditions. The goal of this paper is to inform on the executed test program and the initial results. From the results, it was concluded that in general, a high-quality grass cover on the landside dike slope can withstand high overflow discharges well for 12 to 30 h, without severe erosion damage. Anomalies, such as the presence of animal burrows, reed vegetation, and already present deformations can strongly reduce the resistance of the cover layer and may lead to failure within a couple of hours.

Published: September 2022

This study aims to evaluate the potential impact of climate and land use change on seasonal dynamics of surface runoff within the Upper Tarlung watershed of 71.62 km2. Using the Soil and Water Assessment Tool (SWAT), we simulated the surface runoff under the projections from four global and regional combination models for two representative concentration pathways (RCP4.5 and RCP8.5) and three land use change scenarios. In addition, short (2020–2039), mid (2040–2069), and long-term model simulations (2070–2100) were analyzed compared with a ten-year baseline period (1979–1988). Ensemble SWAT outputs showed that, in spring, surface runoff could decrease by up to 28% or increase by up to 86%, in summer can decrease by up to 69%, while in autumn and winter, increases of approximately two to five times fold are expected. The decreasing tendency is more pronounced under climate conditions, while the sharpest increases are estimated in the comprehensive scenario of climate and land use change by 50%. Those results serve as a support for local water, forest, and land managers in anticipating possible threats and conceiving adaptive strategies to manage the studied watershed efficiently.

Published: September 2022

With the emerging importance of catalysts for water electrolysis, developing efficient and inexpensive electrocatalysts for water electrolysis plays a vital role in renewable hydrogen energy technology. In this study, a 1nm thickness of TiC-supported Ru catalyst for hydrogen evolution reaction (HER) has been successfully fabricated using an electron (E)-beam evaporator and thermal decomposition of gaseous CH4 in a furnace. The prepared Ru/TiC catalyst exhibited an outstanding performance for alkaline hydrogen evolution reaction with an overpotential of 55 mV at 10 mA cm−2. Furthermore, we demonstrated that the outstanding HER performance of Ru/TiC was attributed to the high surface area of the support and the metal-support interaction.

Published: September 2022

Solar energy harvesting is practiced by various nations for the purpose of energy security and environment preservation in order to reduce overdependence on oil. Converting solar energy into electrical energy through Photovoltaic (PV) module can take place either in on-grid or off-grid applications. In recent time Lithium battery is exhibiting its presence in on-grid applications but its role in off-grid application is rarely discussed in the literature. The preliminary capacity and Peukert’s study indicated that the battery quality is good and can be subjected for life cycle test. The capacity of the battery was 10.82 Ah at 1 A discharge current and the slope of 1.0117 in the Peukert’s study indicated the reaction is very fast and independent on rate of discharge. In this study Lithium Iron Phosphate battery (LFP) after initial characterization was subjected to life cycle test which is specific to solar off-grid application as defined in IEC standard. The battery has delivered just 6 endurance units at room temperature before its capacity reached 75% of rated value. The low life of LFP battery in off-grid application is discussed based on State of Charge (SOC) operating window. The battery was operated both in high and low SOC’s in off-grid application and both are detrimental to life of lithium battery. High SOC operation resulted in cell-to-cell variation and low SOC operation resulted in lithium plating on negative electrode. It is suggested that to make it more suitable for off-grid applications the battery by default has to be overdesigned by nearly 40% of its rated capacity.

Authors: Gadalla Amal , Wise Hannah , Farewell Daniel , Hughes Kathryn , Llor Carl , Moore Michael , Verheij Theo JM , Little Paul , Butler Christopher C , Francis Nick A
Published: September 2022

Background

Randomised trials provide high-quality evidence on the effects of prescribing antibiotics for urinary tract infection (UTI) but may not reflect the effects in those who consume antibiotics. Moreover, they mostly compare different antibiotic types or regimens but rarely include a ‘no antibiotic’ group.

Aim

To estimate the effect of antibiotic consumption, rather than prescription, on time to recovery in females with uncomplicated UTI.

Design and setting

Secondary analysis of 14-day observational data from a point-of-care test trial for UTI in primary care in England, the Netherlands, Spain, and Wales, which ran from 2012 to 2014. Clinicians treated patients using their own judgement, providing immediate, delayed, or no antibiotic.

Method

UTI-symptomatic females who either consumed or did not consume antibiotics during a 14-day follow-up were included. Antibiotic consumption was standardised across participants and grouped into either ≤3 or >3 standardised antibiotic days. To account for confounders, a robust propensity score matching analysis was conducted. Adjusted Kaplan–Meier and Cox proportional hazard models were employed to estimate time to recovery and hazard ratios, respectively.

Results

A total ofn= 333 females who consumed antibiotics andn= 80 females who did not consume antibiotics were identified and included in the study. The adjusted median time to recovery was 2 days longer among patients who did not consume antibiotics (9 days, 95% confidence interval [CI] = 7 to 12) compared with those who did (7 days, 95% CI = 7 to 8). No difference was found between those who consumed ≤3 (7 days, 95% CI = 7 to 8) compared with >3 standardised antibiotic days (7 days, 95% CI = 6 to 9).

Conclusion

Consuming antibiotics was associated with a reduction in self-reported time to recovery, but more antibiotics exposure was not associated with faster recovery in this study.

Setiap orang pasti tidak menginginkan bahtera rumah tangganya hancur dan berujung dengan perceraian. Dalam realita hidup banyak dijumpai pasangan-pasangan yang melakukan perceraian dengan berbagai alasan dan itu memberikan dampak bukan hanya terhadap anak-anak, keluarga tetapi juga terhadap pasangan yang bercerai tersebut. Gereja pada umumnya memberikan pendampingan pada waktu pasangan menikah itu hendak bercerai, tetapi setelah keluarnya putusan pengadilan yang mensahkan perceraian mereka, pendampingan pastoral tidak lagi dilakukan. Penelitian ini mengkaji bagaimana pentingnya pendampingan pastoral bagi pasangan bercerai sehingga dapat mengurangi dampak dalam kehidupan mereka yang sedang dalam pra-perceraian ataupun pasca perceraian. Metode yang digunakan adalah studi kepustakaan dan menggunakan instrumen wawancara dengan salah satu pasangan yang bercerai, dan kesimpulan yang didapat adalah betapa penting gereja melakukan pendampingan pastoral bagi pasangan yang melakukan perceraian agar mereka tetap dapat menjalankan dan melanjutkan kehidupan sehari-hari dan membangun kehidupan rohani dengan lebih baik lagi, mencegah terjadinya perzinahan karena kebutuhan biologis yang tidak tersalurkan sebagai konsekuensi logis dari sebuah perceraian, serta tidak tertutup kemungkinan pasangan bercerai ini diarahkan untuk dapat rujuk kembali.apabila mereka tidak tahan bertarak. Kata-kata kunci: Perceraian; pendampingan pastoral; perkawinan Kristen

The task of a servant of God is to carry out two divine mandates at once, the spiritual mandate of salvation and the social mandate of development. Based on the initial study, there were many problems faced by God's servants in service, related to economic, emotional, and spiritual formation, which are serious problems faced by the world community as a result of the Covid-19 pandemic. The church as an institution, or God's servants as implementers of the divine mandate, is required to reformulate the service model that is relevant to the pandemic situation, during or after it. This study aims to examine how to serve the world without being "worldly". The method used is a qualitative approach (qualitative research), in which research results are presented in the form of descriptive data processed from data sets (written, oral, and behavioral observa-tions). The big dilemma above has been studied correctly and deeply through a spiritual approach without neglecting physical needs. So that God's servants can be a source of blessings in their field of service.Abstrak.Tugas seorang hamba Tuhan adalah mengemban dua mandat ilahi sekaligus, mandat spiritual penyelamatan dan mandat sosial pembangunan.

Imagem, pornografia e paridade de participação: uma crítica interdisciplinar
Authors: Guima Tarine
Published: September 2022

Neste artigo discutimos a questão da pornografia – de modo crítico – em três etapas: primeiro, em uma conceituação do que seria a imagem em si mesma, utilizando-se da teoria de Vilém-Flusser (1985), para compreender como a imagem se constitui como uma ferramenta de poder e dominação. Depois, adentramos a questão cinematográfica, apreendendo pontos importantes da crítica feminista ao cinema para, então, ter o devido embasamento para falar sobre um tipo de imagem cinematográfica específica: a pornografia. Quem nos auxilia nessa tarefa é a filósofa política e da linguagem Rae Langton (2009), perpassando uma discussão minuciosa sobre os problemas éticos e políticos da pornografia enquanto palavra, linguagem e imagem, bem como suas significações e impactos no mundo social.

Embora tenha se tornado uma “pandemia” (do grego, pandemías, “todo povo”), o covid-19 é vivida de diferentes maneiras, sendo o risco de infecção e as medidas preventivas nem um pouco equivalentes entre as pessoas. Trazer a lume tais vivências singulares, como daqueles que portam doença renal crônica, é o objetivo deste artigo. Partindo de entrevistas com um paciente de hemodiálise, realizadas pessoalmente e à distância, monstro a pandemia enquanto processo social multiforme, cujos sentidos e narrativas variam na mesma medida que indivíduos e grupos. Trata-se, enfim, de compreender os impactos do vírus e, sobretudo, do isolamento social, nas vidas que já estavam envoltas por alguma perturbação grave antes da pandemia iniciar, a fim de apresentar uma outra realidade desta, menos global e mais local – mas tão crucial quanto qualquer outra.

The materials, obtained from previous (1972-2019) studies of over 300 km of the coastal land strip in Southwestern Kamchatka and the adjoining underwater slope of the Sea of Okhotsk (in the interfluve of the Bolshaya and the Kikhchik rivers) were analyzed. Gold-rich zones (> 60 mg/m3) in the form of subparallel lenses, oriented along the sea shoreline, were identified between 6.3-30 m isobaths in the shallow marine shelf zone. The gold content of the submarine coastal slope correlated directly with the sediments of the upper coastal zone. Higher gold concentrations (up to hundreds of mg/m3) were detected in Holocene marine sediments of the shallow marine shelf in sampling intervals 0 to 2.0 m. They are mostly confined either to the upper, steepest part of the submarine slope or to the first or second terraced level. These are the areas of the most active impact, near the shorelines (modern and submerged), within which glacial and water-glacial formations are often exposed by erosion. Most of the gold concentrate halos related to ancient shorelines, the western boundary of which lies within 25-30 m isobaths, and to paleovalleys, identified by seismoacoustic profiling. In paleovalleys, flooded by the sea and buried under marine sediments, alluvial placers similar to Tikhangou in Primorsky Krai may be revealed. The most promising within the investigated territory was the area of underwater coastal slope within the Severnaya Mitoga - Utka - Khomutina interfluve, between 5.3-30 m isobaths, where concentrate halos with considerable gold concentrations from 60 to 500-1186 mg/m3 had been revealed.

The article discusses the results of studying the material composition of Permian terrigenous deposits in the Dzhigdali, Gizhiga, and Khivach formations in the southeastern part of the Omolon massif. The obtained data interpretation is based on the petrographic research and widely used petrochemical and discriminant paleogeodynamic diagrams. The lithochemical study showed that the deposits had accumulated under conditions of a moderately warm climate with some cooling episodes in the active continental margin settings. Clastic material entered the sedimentary basin from several provenance areas: the Permian Okhotsk-Taigonos volcanic arc, the Precambrian basement of the Omolon massif, and volcanic rock fields of the Kedon series.

Published: September 2022

Platelet detection and counting play a greatly significant role in medical field, especially in routine blood tests which can be used to judge blood status and diagnose related diseases. Therefore, platelet detection is valuable for diagnosing related blood diseases such as liver-related diseases. Blood analyzers and visual microscope counting were widely used for platelet detection, but the experimental procedure took nearly 20 minutes and can only be performed by a professional doctor. In recent years, technological breakthroughs in artificial intelligence have made it possible to detect red blood cells through deep learning methods. However, due to the inaccessibility of platelet datasets and the small size of platelets, deep learning-based platelet detection studies are almost nonexistent. In this paper, we carried out experiments for platelet detection based on commonly used object detection models, such as Single Shot Multibox Detector (SSD), RetinaNet, Faster_rcnn, and You Only Look Once_v3 (YOLO_v3). Compared with the other three models, YOLO_v3 can detect platelets more effectively. And we proposed three ideas for improvement based on YOLO_v3. Our study demonstrated that YOLO_v3 can be adopted for platelet detection accurately and in real time. We also implemented YOLO_v3 with multiscale fusion, YOLO_v3 with anchor box clustering, and YOLO_v3 with match parameter on our self-created dataset and, respectively, achieved 1.8% higher average precision (AP), 2.38% higher AP, and 2.05% higher AP than YOLO_v3. The comprehensive experiments revealed that YOLO_v3 with the improved ideas performs better in platelet detection than YOLO_v3.

Soil is an important element in supporting development activities in the world of civil construction. One type of soil that is often found in South Sumatra is clay. Clay soil is a type of fine-grained soil that is strongly influenced by water content. Each type of clay has a different carrying capacity value. Therefore, an analysis is needed to test the effect of adding a mixture of materials to the clay. A test was carried out to see the effect of adding mixed materials to the soil. In this test, soil samples were taken from the Banyuasin district and mixed with materials in the form of fiber, husk ash, and lime. For variations in soil mixture testing, 0.1% fiber, 2.5% husk ash, and lime consist of 2.5%, 5%, and 7.5%, as well as plain water. The test results show that the addition of a mixture of fiber, husk ash, and cement can improve the physical and mechanical properties of clay, where the optimum addition variation in the 4th variation is a mixture of soil + fiber 0.1% + husk ash 2.5% + lime 5%, which is 52.49%.

Çalışmanın amacı, İlhanlı Devleti’ne bağlı eyaletlerin sayısı ve sınırlarını tespit etmek, bu eyaletlerde nasıl bir yönetim hiyerarşisi kurulduğunun değerlendirmesini yapmaktır. Büyük Moğol İmparatorluğu’nun bir parçası olarak İran merkezli 1256-1353 yılları arasında Ceyhun Nehri’nden Anadolu içlerine kadar alanda hâkimiyet kuran İlhanlıların siyasî tarihleri araştırmacılar tarafından önemli ölçü de irdelenmişse de devlet teşkilatı hususu söz konusu olduğunda birçok meselenin yeterince aydınlığa kavuşturulamadığı görülmektedir. Bunda kaynakların el verişsiz olması ve bu mevzuları çözüme kavuşturacak yeterli resmî vesikanın günümüze ulaşmamasının büyük etkisi vardır. Lakin tüm kaynak azlığına rağmen İlhanlı devlet teşkilatı hakkında bazı bilgilere sahip durumdayız. Bu bilgileri kullanarak da bazı değerlendirmeler yapmak da mümkündür. Bundan hareketle bu çalışmada devlet teşkilatı içerisinde mühim bir yer edinen eyalet teşkilatı hakkında bir değerlendirme yapılacaktır.
Sırbistan'ın ve Osmanlı Sırplarının Makedonya Meselesi'ndeki Yeri
Authors: DURAN Nurbanu
Published: September 2022

Berlin Antlaşması ile Sırbistan bağımsızlık kazanmış, ancak Osmanlı Rumelisi’nde kalan Sırplar Osmanlı hakimiyetinde yaşamaya devam etmiştir. Sırbistan ise bölgede kalan Sırplar yardımıyla ve tarihsel bağlarının vasıtasıyla Makedonya olarak nitelendirilen Kosova, Manastır, Selanik vilayetlerinde hak iddia etmiştir. Bulgarlar ve Yunanlılar gibi Makedonya probleminin bir parçası haline gelen Sırplar, bu probleme ilk çözüm yolu olarak eğitim ve din yolunu kullanarak bölgede propaganda yapmayı seçmişlerdi. Bu amaçla bölgede Sırp kimliğini korumak maksadıyla Sırp okulları kurmak ve kiliselere Sırp din adamlarının atanmasını sağlamak için çalışmışlardı. Bu çabaların yetersiz kaldığı noktada ve Balkanlar’daki diğer halkların da faaliyetlerine müteakip özellikle Bulgarlara karşı silahlı çete faaliyetlerine girişmişlerdir. İlk zamanlar yerel ve küçük çete faaliyetleri olarak nitelendirebileceğimiz girişimler zamanla Sırbistan’ın önce gizlice daha sonra açık olarak desteklediği Çetnik hareketine dönüşmüştür. Bu durum, bölgede Balkan Savaşları’na kadar devam edecek Sırp, Bulgar, Yunan çatışmalarını ve bunlara karşı önlemler almaya çalışan Osmanlı yönetimimin çabalarını içeren bir süreç yaratmıştır.
