26 numaralı Kastamonu Şer'iyye sicilinin transkripsiyon ve değerlendirilmesi (H.1135-1136/M.1723-1724)
(Kastamonu Üniversitesi, 2016) Han, Süleyman
Şerʿiyye sicilleri Türk tarihi açısından zengin bilgiler içeren belgeler olup, kent tarihi araştırmalarında en önemli kaynak olarak ön plana çıkmaktadır. Şerʿiyye sicilleri, merkezden gönderilen her konuyla ilgili ferman, berat, buyuruldu ile iʿlâm ve hüccet gibi kadıların davalarda verdikleri hükümleri içermektedir. Şerʿiyye sicilleri 15-20. yüzyıllar arası Osmanlı tarihi ve kültürünün, hukuki, içtimai, iktisadi ve siyasi kaynaklarıdır. Şerʿiyye sicillerinden yararlanılmadan Osmanlı kentlerinin tarihini ve kültürünü etraflı bir şekilde ortaya koymak mümkün değildir. Bu sebeple yerel tarih araştırmalarında şerʿiyye sicilleri ana kaynak mahiyetindedir. Bu çalışmada 26 Numaralı Kastamonu Şerʿiyye Sicili esas alınmıştır. Bu çalışmanın temel amacı Kastamonu ile ilgili önemli tarihi bilgileri ortaya çıkarmak ve Kastamonu kentinin siyasi, içtimai, idari, iktisadi ve hukuki yönünü etraflı bir şekilde aydınlatmaktır. 26 Numaralı Kastamonu Şer'iyye Sicili H. 1135-1136/M. 1723-1724 yıllarını kapsamaktadır. Bu sicil defteri Kastamonu'ya ait diğer şerʿiyye sicilleriyle birlikte Ankara Milli Kütüphane Mikrofilm Arşivi'nde muhafaza edilmektedir. Söz konusu sicilin değerlendirmesi ile Kastamonu'daki kazaların, mahallelerin, nahiyelerin, nahiyelere bağlı köyler ve divanların isimlerine; tereke kayıtlarından evlerde kullanılan giyim ve süs eşyalarına; tarım aletlerine, silahlara vesair pek çok bilgiye ulaşılmıştır. Ayrıca Kastamonu'daki hukuki olaylar örneklerle açıklanmış; sicilde geçen cami, mescit, vakıf, han, hamam, tekke ve zaviye gibi yapılar ile Kastamonu'nun sosyo-kültürel durumu tespit edilmeye çalışılmıştır.
3-D Mental Rotation Ability Testing with Mixed Reality
(2023.01.01) Piri, Z.; Cagiltay, K.
Mental Rotation ability is a key skill for success in many careers. Thus, accurate measurement of this ability is important. Three-dimensional holographic displays can help students process mental rotation stimuli easier and demonstrate their real performances without the limitations of two-dimensional representations. There are few studies measuring mental rotation ability in Mixed Reality environments. In this study, we transferred a mental rotation test, Purdue Spatial Visualization Test: Rotations (PSVT:R), into Mixed Reality. We compared the 2-D and 3-D versions of the test in terms of mental rotation performance and cognitive load with 47 participants. While the accuracy of 2-D and 3-D PSVT:R did not differ significantly, the 3-D test induced a lower cognitive load than the 2-D version. Gender difference was observed in the 2-D test but not in the 3-D test. 3-D PSVT:R is an authentic and reliable tool for measuring spatial ability. Moreover, it can be used for training purposes.
A Climate-Sensitive Approach for Determining the Urban Growth Boundaries: Towards a Spatial Exploration for Bursa, Türkiye
(2023.01.01) Isinkaralar, O.
Population growth is inevitable in urban areas responsible for climate crises worldwide, and urban development is affected by processes fed by many dynamics. Predicting and planning the growth limits of the city effectively is a critical issue for achieving sustainable urban growth and managing climate risks. The study used the cellular automata-Markov chain method to define development areas regarding natural structure and land use/land cover. It aimed to present a method that can be applied to different urban areas by focusing on effective urban growth management with a climate-sensitive approach. It offered a climate-sensitive approach to determining growth limits according to scenarios. The boundaries of 2030 have been determined for the city of Bursa, which exhibited an increased average summer value of the land surface temperature from 24 degrees C to 45 degrees C between 2012 and 2021, stands out with its natural riches, and shows a rapid urban growth trend. The proposed method modeled the limits of urban growth with a climate-sensitive approach, and the model's suitability was demonstrated by Kappa statistics (Klocation = 0.8884). The determined urban boundary will reduce the rate of the urban built-up area from 86% to 70% by 2030. While the climate crisis threatens all life, urban activities, urban growth, and sprawl continue to increase rapidly. However, the growth of urban areas within certain limits is a critical need for engineering and urban planning. For decision makers, spatially determining the limits of human intervention in nature is an important guideline. Extreme weather events and disasters such as floods, tsunamis, and changes in water levels brought about by climate change can potentially cause chaotic crises. Loss of life and economic crises may occur in possible processes. Therefore, measures must be taken on behalf of humanity and life to adapt to climate effects and keep the level of impact under control. Spatial models based on a wide range of temporal contexts have a structure that broadens our perspective. The study provides an approach that can be implemented in various fields with models produced based on scenarios.

A novel fixed point iteration process applied in solving the Caputo type fractional differential equations in Banach spaces
(2024.01.01) Okeke, G.A.; Ugwuogor, C.I.; Alqahtani, R.T.; Kaplan, M.; Ahmed, W.E.
We introduce the modified Picard-Ishikawa hybrid iterative scheme and establish some strong convergence results for the class of asymptotically generalized phi-pseudocontractive mappings in the intermediate sense in Banach spaces and approximate the fixed point of this class of mappings via the newly introduced iteration scheme. We construct some numerical examples to support our results. Furthermore, we apply the Picard-Ishikawa hybrid iteration scheme in solving the nonlinear Caputo type fractional differential equations. Our results generalize, extend and unify several existing results in literature.
Advanced NH3 Detection by 1D Nanostructured La:ZnO Sensors with Novel Intrinsic p-n Shifting and Ultrahigh Baseline Stability
(2024.01.01) Ajjaq, A.; Bulut, F.; Ozturk, O.; Acar, S.
Due to its stability, transportability, and ability to be produced using renewable energy sources, NH3 has become an attractive option for hydrogen production and storage. Detecting NH3 is then essential, being a toxic and flammable gas that can pose dangers if not properly monitored. ZnO chemiresistive sensors have shown great potential in real NH3 monitoring applications; yet, research and development in this area are ongoing due to reported limitations, like baseline instabilities and sensitivity to environmental factors, including temperature, humidity, and interferent gases. Herein, we suggest an approach to obtain sensors with competitive performance based on ZnO semiconducting metal oxides. For this purpose, one-dimensional nanostructured pure and La-doped ZnO films were synthesized hydrothermally. Incorporating large rare earth ions, like La, into the bulk lattice of ZnO is challenging and can lead to surface defects that are influential in gas-sensing reactions. The sensors experienced a temperature-induced p-n shifting at about 100 degrees C, verified by the Hall effect and AC impedance measurements. The doped sensor showed exceptional stepwise baseline stability and outstanding performance at a relatively low operating temperature (150 degrees C) with a sensing response of 91 at best (@ 50 ppm NH3) and recorded a tolerance to water vapor up to 70% RH. Alongside p-n shifting, the enhanced performance was discussed in correlation with La doping-triggered changes in the nanostructural and surfacial properties of the films. We validated the proposed technique by producing similar sensors and performing multiple replicates to ensure consistency and reproducibility. We also introduced the fill factor concept into the gas sensor field as a new trustworthy parameter that could improve sensor performance assessment and help rate sensors based on deviation from ideality.

Burden and associated characteristics in caregivers of Parkinson's disease patients
(2024) Inaltekin, A.; Kocatürk, I.
Background: Parkinson's disease (PD) increases patient load and requirements of care. Determining the burden on PD patients' caregivers and associated factors may help to identify methods to reduce caregiver burden. This study investigated the factors associated with caregiver burden among PD patients caregivers. Methods: Eighty-five PD patients and 85 caregivers were included in the study. Zarit Burden Interview (ZBI) was used to measure caregiver burden; the Ways of Coping Scale (WCS) was used for coping; Modified Hoehn-Yahr Staging (MHYS) was used for staging patients. The International Parkinson and Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) parts 1 and 3 were used to evaluate non-motor and motor problems. Caregivers' depression and anxiety levels were evaluated with the Beck Depression Inventory and Beck Anxiety Inventory (BAI). Spearmen correlation coefficient was used to evaluate the relationship of variables with the ZBI score, and multiple linear regression analysis was used to determine the predictors of the ZBI score. Results: A positive significant relationship was found between the ZBI score and BAI score, MHYS score, WCS total score, and subscales: keeping to self, seeking refuge in fate, and seeking refuge in supernatural forces. MHYS score, WCS total score, BAI score, and MDS-UPDRS-1 were predictors of the ZBI score. Conclusions: The anxiety levels of caregivers, their ways of coping, and the patient's stage of the disease are important in caregiver burden. Coping ways can be changed to reduce the care burden. Developing psychological interventions for caregivers to change their coping styles can be important.
Chestnut blight (Cryphonectria parasitica (Murr.) Barr) disease incidence and its effect on the morphological and anatomical features of Castanea sativa trees
(John Wiley and Sons Inc, 2024) Keleş, S.Ö.; Ünal, S.; Akan, S.; Karadeniz, M.
Sweet chestnut (Castanea sativa) is an ecologically and economically valuable tree species worldwide. Various pathogens, both endemic or introduced, cause severe damage or death to chestnut trees. Chestnut blight, caused by the fungus Cryphonectria parasitica, is one of the most devastating plant diseases known which influences chestnut trees in all major cultivation regions. The work presented here aimed to investigate how the incidence of chestnut blight varied between trees growing at two altitudes (200–400 m vs. 400–600 m) and to determine the impact of chestnut blight on tree-ring width, morphology and anatomy of C. sativa trees. The incidence of C. parasitica infections was greater at 200–400 m than at 400–600 m. Greater stem diameters were found at 200–400 m than at 400–600 m. There were no differences in stem diameters and heights, however, between healthy and C. parasitica infected chestnut trees. The anatomical characteristics of wood were also compared between healthy and C. parasitica-infected chestnut trees. Fibre cell traits (length/width, lumen width, lumen area) were higher in healthy trees than in C. parasitica-diseased trees. Vessel diameters were greater in infected compared with healthy trees. Tree ring widths and wood anatomical characteristics therefore were significantly influenced by C. parasitica infections.
Climate change in tourism: Understanding the impacts and opportunities for sustainability
(Emerald Group Publishing Ltd., 2024) Tanrisever, C.; Pamukçü, H.; Baydeniz, E.
Climate change places significant pressure on the tourism sector by altering environmental and socio-economic conditions that influence tourist behaviour and the attractiveness of destinations. Rising temperatures, changing precip¬itation patterns and the increasing frequency and severity of extreme weather events affect tourism supply and demand. On the supply side, climate change threatens tourism infrastructure, natural attractions, recreational opportu¬nities and accessibility of destinations. Coastal destinations are particularly vulnerable to sea-level rise and coastal flooding, which can damage tourism assets. On the demand side, changing climatic conditions alter visitor comfort levels, health risks and the seasonality of destinations, influencing tourists' choice of destinations. In addition, small island destinations face unnecessary risks due to their economic dependence on climate-sensitive activities such as beach and nature tourism. Adapting the tourism sector to climate change requires reducing vulnerability through diversification, green infrastructure, ecosystem conservation, community-based adaptation and policy support. Mitigating tourism's contribution to climate change requires minimising energy use, switching to renewable energy, improving efficiency, reducing long-haul flights and promoting sustainable consumption and production. Collective and concerted efforts by all stakeholders are needed to transition to a climate-resilient and low-carbon tourism sector that continues to provide socio-economic benefits while minimising its environmental footprint.

Ecotourism: For a sustainable future
(Emerald Group Publishing Ltd., 2024) Baydeniz, E.; Çilginoglu, H.; Sandikci, M.
Ecotourism is a sustainability approach that has emerged as an alternative to the negative environmental impacts of tourism, where natural, cultural and historical values are used as sources. Ecotourism is a nature-based tourism activity that ensures the sustainability of natural resources and promotes the economic development of local populations. It also preserves sociocultural values and protects the ecological system for future generations. However, if ecotourism is well-controlled, it can positively affect nature, natural life, local people and the local and national economy. This study highlights the impor¬tance of ecotourism for sustainability in the tourism industry. It examines ways to deal with the ecotourism phenomenon. In this direction, the study defines the concepts of ecological tourism and sustainability. It describes the general characteristics of ecotourism and sustainable tourism and the developing and potential environmental impacts associated with them. The study highlights that any tourist activity that does not have a sustainable quality cannot be long-term and will increase awareness on this topic.
EFFECT OF NANOPARTICLE SHAPE ON NANOFLUID FLOW IN CONICAL HELICAL TUBE
(2024) Altunay, F.M.; Ali, M.A.M.; Gurdal, M.; Pazarlioglu, H.K.; Arslan, K.; Gedik, E.
The nanofluid flow in a conical helical tube was numerically investigated. The study has been carried out in three-dimensional laminar flow (85.73 <= De <= 175.55) condition. Al2O3-water nanofluid with different nanoparticle volume fractions (1.0%, 2.0%, 3.0%) has been used as the working fluid in the numerical analyzes. In addition, studies were carried out for blade, platelet, and cylindrical nanoparticle shapes. The average Nusselt numbers and the average Darcy friction factors have been used to estimate the flow and heat transfer performance of nanofluid flow in the conical helical tubes. Numerical results of the study have been presented as the variation of average Nusselt number and average Darcy friction factor with Dean number, nanoparticle shape, and nanoparticle volume fraction. As a result, the highest convective heat transfer performance has been obtained for the cylindrical nanoparticle shape of the %3.0 Al2O3-water nanofluid.
Effects of Different Phosphorus Sources on the Yield and Yield Components of Forage Pea
(2023-05-01) Dilara KAYNAR, Binali ÇOMAKLI
This experiment was conducted to evaluate the effects of two different doses (B0 or B1) of phosp horus-solubilizing bacteria (Bacillus megaterium M-3) inoculation, two different doses (0 or 3 t ha−1) of poultry manure, and three different doses (0, 50, and 100 kg P 2O5 ha−1) of commercially available phosphorus fertilizer on the dry matter yield, plant height, crude protein, neutral deter- gent fiber, and acid detergent fiber contents of forage pea in the irrigated condition of Erzurum between 2009 and 2010. While the effects of bacteria inoculation and poultry manure applica- tions on dry matter yield varied over the years, an increase was observed in dry matter yield with increasing doses of phosphorus fertilizer. In addition, considering the 2-year averages, the highest dry matter yield considering the 2-year averages was obtained with the application of bacteria, poultry manure, and phosphorus fertilization together. Therefore, in order to obtain the highest dry hay yield in Erzurum and similar ecological conditions with low and/or medium phosphorus content in the soil and irrigated, Bacillus megaterium inoculation and 3 t ha −1 poultry manure together with 100 kg ha−1 P2O5 application can be recommended.
