Monitoring wetland cover changes and land surface temperatures using remote sensing and GIS in Göksu Delta
No full textWetlands provide necessary ecosystem services, such as climate regulation and contribution to biodiversity at global and local scales, and they face spatial changes due to natural and anthropogenic factors. The degradation of the characteristic structure signals potential severe threats to biodiversity. This study aimed to monitor the long-term spatial changes of the G & ouml;ksu Delta, a critical Ramsar site, using remote sensing techniques. It seeks to analyze the relationship between these changes and land surface temperature (LST) and predict future land use patterns through machine learning (ML) methods. In this context, the normalized difference vegetation index, modified normalized difference water index, normalized difference bareness index, and normalized difference moisture index remote sensing spectral index analyses and LST maps were generated using Landsat 8 Operational Land Imager (OLI) satellite imagery for 1985, 2000, 2015, and 2023. Kappa accuracy assessments demonstrated a high level of agreement between the generated maps and ground truth data. Pearson correlation analysis was used to assess the consistency of the relationship between spectral index analyses and LST, revealing a statistically significant correlation at the 0.01 level. The study revealed that Lake Akg & ouml;l lost 58.85% of its water body over the 38 years of monitoring the delta. This loss was primarily attributed to increased LST and human activities. The land use land cover model for the year 2031, developed using artificial neural networks and cellular automata from ML methods, projected a 7.50% decrease in total water bodies, a 46.94% reduction in vegetated areas, and a 36.85% increase in nonvegetated areas. In conclusion, it was emphasized that the adverse land use trends within the G & ouml;ksu Delta are expected to persist, degrading its ecosystem services and values. In this context, the study's findings can be utilized to identify strong strategies for protecting the delta. Key points This study monitored the temporal change of the G & ouml;ksu Delta, a significant Ramsar site.It was observed that this change has been realized due to the effect of land surface temperature and human activities such as agricultural efforts.Similar findings have also been reported in international studies; in addition, the machine learning algorithms predicted that land use would change in the near future.It was concluded that the conservation policies of such essential areas should be improved
The role of financial inclusion and human capital on the ecological deficit
No full textThis study explores the effects of financial inclusion, human capital, energy consumption, urbanization, and per capita income on the ecological deficit, using moments quantile regression (MMQR) model with data from 34 OECD countries. In the study, a panel dataset covering the period from 1994 to 2018 is used. According to the MMQR results, both financial inclusion and human capital have a stronger impact on environmental deficit at the higher quantiles (such as energy consumption, population, and per capita income square). In the face of a higher deficit, an increase in financial inclusion increases pollution more, while human capital decreases it. © The Author(s), under exclusive licence to Springer Nature B.V. 2023

The aim of this study is to systematically examine the effects of tailored interventions, such as group education and telephone counseling, on breast cancer screening behaviors and health perceptions among women with low socioeconomic status. The study seeks to evaluate how these interventions influence women's health awareness, their adoption of screening behaviors, and their access to healthcare services. Method: This study is a randomized controlled trial conducted at a family health center. Data were collected by using the Diagnostic Form, Breast Cancer Health Belief Model Scale, Mammography Self-efficacy Scale, and Breast Cancer Fear Scale. The study sample consisted of 123 women. The Tailored Interventions in Breast Cancer Screenings (TIBCS) included group education and telephone counseling. These tailored interventions were based on the health belief model. The study consisted of two experimental groups those receiving tailored group education (N=41) and those receiving tailored telephone counseling (N=41) and one control group receiving standard care (N=41). A pre-test and post-test control group design was used in the study, and the outcome variables were evaluated before the intervention and at the 3rd and 6th months after the intervention. Data were collected by using the Socioeconomic Status Scale, Diagnostic Form, Breast Cancer Health Belief Model Scale, Mammography Self-Efficacy Scale, Breast Cancer Fear Scale, and Breast Cancer Fatalism Scale. The NCSS (Number Cruncher Statistical System) program was used for statistical analysis. Data were evaluated by using descriptive statistical methods. Results: The study found that TIBCS increased the rates of regular self-breast examinations, clinical breast examinations, and mammography screenings (p<0.05). In the experimental groups of the TIBCS, it was observed that self-breast examination benefits, mammography benefits, confidence, and health motivation perceptions increased, while perceived barriers to self-breast examination and mammography decreased (p<0.05), with no change in susceptibility perception (p>0.05). Similarly, in both experimental groups, women's perceptions of mammography self-efficacy increased, while fear and fatalism perceptions showed a significant decrease (p<0.05). Conclusion: TIBCS applied to women with low socioeconomic status is effective in increasing the rate of breast cancer screening behaviors and improving health perceptions. Therefore, tailored interventions are considered to be beneficial in future studies.The authors received no financial support nor any sponsorship for research, authoeship or publication.

The Religious, Political, and Economic Dimensions of Sultan al-Malik al-Kamil’s Prohibition of the Regaib Prayer
Get PDFEyyûbîler dönemi, mezhep ihtilafları ve dini meselelerdeki tartışmaların yoğun olduğu bir dönemdir. El-Melikü’l-Kâmil, İzzeddin İbn Abdüsselâm’ın fetvasına dayanarak Regaib namazını yasaklamış ve bu yasak dini, siyasi ve iktisadi boyutlarıyla ülkede önemli etkiler yaratmıştır. Eyyûbîlerin coğrafi olarak genişlemesiyle yönetim sahası artmış, Suriye, Mısır ve el-Cezire’de yaşayan ulemanın etkinliği üst düzeyde olmuştur. El-Melikü’l-Kâmil, Selâhaddin ve el-Melikü’l-Âdil gibi ülkede birliği sağlamış, Haçlılara karşı başarılı seferler düzenlemiş ve Haçlılarla yapılan antlaşmalarda başarıya ulaşmıştır. El-Melikü’l-Kâmil’in dini, siyasi ve kültürel eğitimi, onun yönetimsel kararlarında isabetli olmasını sağlamıştır. El-Melikü’l-Kâmil, saltanatının ilk yıllarında Mısır’ı hedef alan Haçlı seferiyle uğraşmış, Dimyat’ı savunurken tahta çıkışında şehir Haçlılar tarafından ele geçirilmiştir. Eyyûbîler, Dimyat’ı kaybettikten sonra büyük güç kaybına uğramış, Müslüman emir ve hükümdarlardan destek talep etmişlerdir. El-Melikü’l-Kâmil ile el-Melikü’l-Muazzam’ın Eyyûbî ülkesinde birliği sağlaması, Haçlıların kıskaç altına alınmasına ve V. Haçlı seferinin sona ermesine neden olmuştur. El-Melikü’l-Kâmil dönemi, ülke içinde birlik ve düzenin sağlanması açısından önemli olmuştur. Hükümdarlar, Batinîler ve Haçlılara karşı daha etkili mücadele edebilmek için alimlere, özellikle fakihlere büyük önem vermişlerdir. Din ilimleri, Eyyûbîlerde birinci sırada yer almış ve medreselerde öğretilmiştir. İbnü’s-Salâh, selefi görüşü benimsemiş, Kuran ve hadisleri tevil etmeyi doğru bulmamış, Batinîlere karşı sultan ve emirleri uyarmıştır. İbnü’s-Salâh'ın etkisiyle felsefe ve mantık ilminin medreselerde okutulması engellenmiş, İbn Abdüsselâm da benzer görüşleri savunmuştur. İbn Abdüsselâm, bidatlarla mücadele etmiş, Regaib namazını bidat olarak değerlendirmiştir. İbn Ebû Rendeka et-Turtûşî’ye göre bu namaz ilk defa 1087 yılında Kudüs’te ortaya çıkmış, İbn Abdüsselâm’ın çabaları ve Eyyûbî Sultanı Melik Kamil’in direktifleriyle yasaklanmıştır. İbn Abdüsselâm’ın fetvası sayesinde Regaib namazı yasaklanmış, el-Melikü’l-Kâmil’in bid‘atlara karşı hassasiyeti nedeniyle dini, siyasi ve iktisadi etkileri olmuştur. Regaib namazının toplu halde kılınmasının halkı etkilediği ve zeytinyağı gibi temel ve değerli kaynakların israf edilmesine yol açtığı belirtilmiştir. Eyyûbî Sultanı, vakıf mallarının tükenmesini önlemek ve daha hayırlı işlere yönlendirmek amacıyla bu bid‘ati yasaklamış, İbn Abdüsselâm’ın fetvasına uygun hareket etmiştir. Eyyûbî Sultanının Regaib namazını yasaklamasında ekonomik kaygılar da etkili olmuştur. Nitekim, İbn Abdüsselâm’a bu konuda fetva sorulduğunda, olayın iktisadi yönüyle ilgili de cevap vermiş ve meselenin sadece dini yönüyle yetinmemiştir. Eyyûbî ülkesinde, özellikle Kahire’de, pek çok cami ve mescidin bulunması ve Regaib gecesinde yakılan binlerce kandilin harcandığı zeytinyağının beytülmalden alınması nedeniyle harcamalar oldukça yüksekti. Ayrıca, bid‘at olan ve Allah'ın ve Resul’ünün emretmediği bir ibadet için beytülmalden zeytinyağı alınması ve kullanılması uygun değildi. El-Melikü’l-Kâmil, özellikle Haçlılar ve civar devletlerle yaptığı mücadelelerde büyük bir maliyet üstlendiğinden, bu tür harcamaları ortadan kaldırmak istemiş ve İbn Selam’ın fetvasına uygun hareket ederek Regaib namazını yasaklamıştır.The Ayyubid period was marked by intense sectarian conflicts and religious debates. Al-Malik al-Kamil, acting on the fatwa of Izz al-Din Ibn Salam, banned the Regaib prayer, which had significant religious, political, and economic implications. As the Ayyubids expanded geographically, their governance and the influence of scholars in Syria, Egypt, and al-Jazira increased significantly. Al-Malik al-Kamil, like Salah ad-Din and al-Adil, managed to unite the country, launched successful campaigns against the Crusaders, and secured beneficial treaties. His education in religious, political, and cultural matters enabled him to make sound decisions. In the early years of his reign, al-Malik al-Kamil defended Egypt against Crusader invasions, and during his ascension, Damietta was captured by the Crusaders. The loss of Damietta led to significant power loss, prompting calls for support from Muslim leaders. The unity brought by Kamil and al-Muazzam in the Ayyubid state helped encircle the Crusaders, ending the Fifth Crusade and achieving an eight-year peace. Kamil's era was crucial for establishing internal unity and order. During the Ayyubid period, social life was governed by fiqh, making jurists highly respected. Leaders valued scholars, especially jurists, for their role in combating Batinism and Crusader invasions. Zengi atabeg Nur ad-Din Zengi and Ayyubid Sultan Salah ad-Din opposed philosophical sciences and mystical philosophy. Religious sciences held the highest priority and were taught in madrasas. Ibn Salah, an adherent of the Salafi view, opposed interpreting the Quran and hadiths and warned rulers against the Batinis. His influence led to the exclusion of philosophy and logic from madrasas. Izz al-Din Ibn Abd al-Salam shared these views and fought against innovations in religion, deeming the Regaib prayer a bidah. According to Ibn Abu Randaqah al-Turtushi, this prayer first appeared in Jerusalem in 1087. Due to Ibn Abd al-Salam’s efforts and directives from Ayyubid Sultan al-Malik al-Kamil, it was banned. Ibn Salam's fatwa resulted in the prohibition of the Regaib prayer, reflecting al-Malik al-Kamil’s sensitivity to bidahs and its religious, political, and economic consequences. The communal performance of the Regaib prayer led to public influence and waste of resources like olive oil. The Ayyubid Sultan banned this practice to prevent the depletion of waqf assets and redirect resources to more beneficial uses, aligning with Ibn Salam’s fatwa. Economic concerns also influenced al-Malik al-Kamil's decision, as significant expenditures on olive oil for candles during the Regaib night were unsustainable, especially amidst the costs of Crusader conflicts. Thus, to curb these expenditures, he banned the Regaib prayer, adhering to Ibn Salam’s fatwa
Can the image of food mislead the brain? Neurogastronomy research with EEG and emotion recognition
No full textThis is a research conducted in the discipline of neurogastronomy, which studies how food presentation affects our brains, using traditional sensory assessment, EEG, and measures of emotion recognition technology to probe how visual presentation affects tastes and emotions. With 21 participants, taste scores, brain waves, and facial expressions were measured during three separate eating experiences of the same meal. The results showed that visual presentation had a significant effect on both taste perception and emotional experiences. Thus, liking and positive emotional response were both significantly influenced by the visual appearance of the food, such that foods rated as most visually appealing were more likely to be liked and evoke more positive emotional responses. These results underscore the role that visual aesthetics have in augmenting consumer satisfaction. It is asserted that the findings add to the body of literature on neurogastronomy and help build understanding on how food presentation impacts brain and behavior. The research offers an innovative and unique methodology regarding experimental neurogastronomy, which is a significant gap in the literature
Figure and space in Avni Lifij's paintings
No full textTürk Resim Sanatı içinde önemli yere sahip olan 1914 Kuşağı, Çallı Kuşağı olarak isimlendirilen ressam grubu içerisinde bulunan Hüseyin Avni Lifij, 1914 Kuşağı Ressamları ile birrlikte dönemin resim sanatına yeni bir bakış açısı getirmiştir. Kompozisyonda figürün çağdaş anlamda cesaret ile kullanılması için gayret harcamıştır. Avni Lifij 1886' da Samsu'un Ladik ilçesinde doğmuş, İstanbul'da büyümüş ve yetişmiş, İstanbul'da başladığı tahsiline Paris'te "l'Ecole Nationale Speciale des Beaux-Arts" devam etmiştir. Yurda döndükten sonra farklı okullarda öğretmenlik görevi üstlenmiştir. Ülkemizde, döneminde farklı gazete ve dergilerde eleştiri yazıları kaleme almış, bir çok sergide eserleri sergilenmiştir. Genç yaşında Osman Hamdi Bey ile tanışması ve daha sonrasında Halife Abdülmecit Efendi ile tanıştırılması sanat hayatının başlangıcında, yaşamında dönüm noktası olmuştur. Osman Hamdi Bey'in desteği ve Halife Abdülmecit Efendi tarafından sağlanan burs ile Fransa'ya sanat eğitimine gönderilmiştir. Fransa'da 1909 ile 1912 yılları arasında dört yıl sanat eğitimi almıştır. Lifij'in Fransa'da bulunduğu yıllarda Avrupa'da sanat anlamında önemli değişiklikler olmakta, empresyonizm etkisini göstermekteydi. Lifij Avrupa'da bulunduğu dönem içerisinde yaşanan sanatsal değişimi izleme şansı bulmuştur. 19. Yüzyıl sonlarına başlayan değişim, 20. Yüzyıl başlarında gelişerek varolan sanat akımlarını etkilemiştir. Bu değişim ile izlenimcilik, dışavurumculuk ve kübizm akımlarının varoluş süreci başlamıştır. Lifij bu süreçte ortaya çıkan eserleri ve sanatçılarını yakından tanıma fırsatı elde etmiştir. Lifij'in eserlerini incelediğimizde, çok sayıda poşad tekniğinde yapılmış çalışma görmek mümkündür. Bunlar genellikle küçük ebatlarda yağlıboya çalışmalardır. Poşad çalışmalarına bakıldığında, figürlü ve figürsüz peyzajlar olarak görülmektedir. Lifij'in Poşadlarında izlenimci tekniğin yanısıra, kimi zaman dışavurumcu üsluba rastlanır. Çalışmalarında empresyonist etkilerin yoğun hissedildiği figürlü kompozisyonları dikkati çekmektedir. Peyzajlarında izlenimci üslubun içerisinde romantizm ve sembolizm etkileri görülürken, kuvvetli bir desen anlayışı ön plana çıkmaktadır. Almış olduğu akademik eğitim, kompozisyonlarında kendini göstermektedir. Çalışmalarında paletindeki renkler kimi zaman pastel, kimi zaman ise konuların özelliklerine göre sıcak renkler olabilmektedir. Lifij'in eserlerinde naürmart ve deniz kıyısı konulu kompozisyonlara rastlanamamaktadır. Sanatçının kendi üslubu içerisinde daha ciddi konulara eğilmek istemiş olması bu türden kompozisyonları çalışmasını engellemiş olabilir. Lifij fotoğraf sanatına da ilgi duymuş ve sanatsal değeri yüksek çalışmalar ortaya çıkarmıştır. Avni Lifij, usta bir desenci, empresyonist bir doğa ressamıdır. Mekan figür çözümlemelerindeki farklı yaklaşımları ile özgün bir kişilik, kompozisyon içindeki denge ve estetiği ön plana çıkaran, sanatçı kişiliği ile dikkat çeken, Türk Resim Sanatının en önemli temsilcilerindendir.Hüseyin Avni Lifij, who is a member of the painter group called the 1914 Generation, Çallı Generation, which has an important place in Turkish Painting Art, brought a new perspective to the painting art of the period together with the 1914 Generation Painters. He made an effort to use the figure in the composition with courage in a contemporary sense. Avni Lifij was born in the Ladik district of Samsu in 1886, grew up and was raised in Istanbul, and continued his education, which he started in Istanbul, in Paris at "l'Ecole Nationale Speciale des Beaux-Arts". After returning home, he took on a teaching position in different schools. In our country, he wrote critical articles in different newspapers and magazines during his time, and his works were exhibited in many exhibitions. Meeting Osman Hamdi Bey at a young age and later being introduced to Caliph Abdülmecit Efendi was a turning point in his life at the beginning of his artistic life. With the support of Osman Hamdi Bey and a scholarship provided by Caliph Abdülmecit Efeni, he was sent to France for art education. He received art education in France for four years between 1909 and 1912. During the years Lifij was in France, there were important changes in terms of art in Europe and impressionism was showing its influence. Lifij had the chance to observe the changes that took place during his time in Europe. The change that started in the late 19th century developed in the early 20th century and affected the existing art movements. With this change, the process of existence of impressionism, expressionism and cubism movements began. Lifij had the opportunity to closely get to know the works and artists that emerged during this process. When we examine Lifij's works, it is possible to see many works made in the poşad technique. These are generally small-sized oil paintings. When we look at his poşad works, they are seen as landscapes with and without figures. In addition to the impressionist technique, sometimes an expressionist style is encountered in Lifij's poşads. The figurative compositions in which impressionist influences are felt intensely in his works are noteworthy. While the influences of romanticism and symbolism are seen in the impressionist style in his landscapes, a strong understanding of pattern comes to the fore. The academic education he received shows itself in his compositions. The colors on his palette in his works can sometimes be pastel, and sometimes warm colors depending on the characteristics of the subjects. There are no compositions with the themes of naürmart and seashore in Lifij's works. The artist's desire to focus on more serious subjects within his own style may have prevented him from working on such compositions. Lifij was also interested in photography and produced works of high artistic value. Avni Lifij is a master pattern maker, an impressionist nature painter and an original personality with his different approaches in spatial figure analyses, who emphasizes balance and aesthetics in composition, and is one of the most important representatives of Turkish Painting Art, drawing attention with his artistic personality
Methylene blue adsorption by Quercus cerris acorn shell based activated carbon: equilibrium, kinetic, and thermodynamic studies
No full textThe present study demonstrates that Quercus cerris acorn shell-derived activated carbon can serve as an effective and promising adsorptive material for the cationic Methylene Blue removing from aqueous solution via adsorption technique. The study explored how adsorbent concentration, temperature, initial adsorbate concentration, contact time, and pH influence MB adsorption onto QCAC. QCAC dosages of 30, 45, 60, 75, 90, and 105 mg/50 mL provided nearly 99.70% MB removal efficiencies for 50, 100, 150, 200, 250, and 300 mg/L MB solution concentrations. It was found that the adsorption of MB on QCAC is notably impacted by solution pH, and that higher temperatures enhance the adsorption process, particularly at lower adsorbent concentrations. Adsorption properties were characterized by utilizing various adsorption isotherms, e.g. Temkin, Langmuir, Freundlich, and Jovanovi & cacute; and by utilizing various kinetic models such as pseudo-first-order, and pseudo-second-order, and intra-particle diffusion models via their non-linear forms. When using non-linear version of isotherm models isotherm model, Freundlich and Temkin isotherm aligned well with the experimental data. The study evinced that the adsorption kinetics of QCAC by MB adapted well to kinetic model for pseudo-second order and the application of the particle-diffusion model contributed insights into MB adsorption kinetic mechanism on QCAC. Additionally, thermodynamic variables for the MB adsorption on QCAC were assessed, disclosing that MB adsorption process on QCAC was endothermic, reversible, and feasible.Ministry of Education, Science and Technology of Kosovo [2-2541-1]This work was funded by the Ministry of Education, Science and Technology of Kosovo under the Project Number of 2-2541-1 in 202
Effects of the Dietary Blue-Green Algae (Spirulina platensis) Supplementation and Egg Storage Period on Egg Quality Traits, Blastoderm Characteristics and Hatching Results of Mast Geese (Anser anser)
No full textThis study aimed to determine the effects of the dietary Spirulina platensis supplementation and egg storage period on egg quality traits, blastoderm characteristics and hatching results of Mast geese. For this purpose, the control group was fed the standard enterprise diet, while the experimental group received the same diet supplemented with 0.5% S. platensis. Quality traits of the eggs (shape index, shell thickness, breaking strength, albumen/yolk ratio, albumen index and yolk colour) were evaluated according to diet groups. Except for the yolk ratio of these traits, the mean values obtained from the experimental group were higher than the mean values obtained from the control group (p < 0.05; p < 0.001). Dietary supplementation of S. platensis did not affect blastoderm diameter (BD) but significantly increased the blastoderm viable cells (BVCs) (p < 0.001). Although early embryonic mortality (EEM) was statistically significantly affected by diet groups and storage time, late embryonic mortality (LEM) was affected only by diet groups (p < 0.001). Dietary S. platensis supplementation significantly increased pipped (PIP) classified under the LEM (p < 0.001). Storage period affected internal and external egg traits at different statistical significance levels. As the storage time increased, the breaking strength (p < 0.05), albumen ratio, albumen index, yolk index, Haugh unit decreased (p < 0.01; p < 0.001), while the yolk ratio, and albumen pH increased (p < 0.001). An increase in BD, and a decrease in BVCs were determined with prolonged storage period (p < 0.001). In the classification of LEM, the storage period significantly affected unabsorbed yolk sac (UYS) and the PIP. With prolonged storage time, UYS and PIP significantly increased (p < 0.05; p < 0.01), which is classified under LEM. According to these results, we suggest that S. platensis supplementation to goose diets would be beneficial, but the detailed further studies are needed for more effective results.Scientific Research Projects Coordination Unit of Tekirdag Namimath;k Kemal University [NKUBAP.10.

No full textÇalışma 5 aşamalı olarak yürütülmüştür. Çimlenme denemesi 11 genotip ve farklı sıcaklık uygulamaları ile 3 tekrarlamalı olarak kurulmuştur. Fide boyu, kök uzunluğu, çimlenme hızı ve çimlenme gücü özellikleri belirlenmiştir. Birinci soğuk uygulama denemesinde 11 genotipte fide döneminde meydana gelen soğuğa dayanıklılık ölçütü olarak soğuk zararı gözlemleri ile belirlenmiştir. İkinci soğuk uygulama denemesinde 30 genotipte Zadoks 23. dönemde farklı soğuk uygulamaları yapılarak kurulmuştur. Soğuk zararı gözlemi, bitki örtüsü sıcaklığı, klorofil oranı, bitkide kardeş sayısı, fide boyu ve stoma özellikleri incelenmiştir. Üçüncü soğuk uygulama denemesinde 11 genotipte Zadoks 31. dönemde farklı soğuk uygulamaları yapılarak kurulmuştur. Soğuk zararı gözlemi, başaklanma gün sayısı, mumsuluk, verim unsurları ve sterilite belirlenmiştir. Tarla denemesi, 500 bitki/m² ekim sıklığı ile 5 tekrarlamalı olacak şekilde 11 genotip ile yürütülmüştür. Çalışmada bitki büyüme şekli, başaklanma gün sayısı, mumsuluk, tane verimi ve verim unsurları, kalite özellikleri incelenmiştir. Yapılan varyans analizi ve önemlilik testi sonucunda soğuk uygulamaları, ve soğuk zararı gözlemleri yönünden genotipler arasında önemli bir değişimin olduğu gözlemlenmiştir. Birinci soğuk uygulama denemesinde -5°C'de Krasunia Odes'ka ve Sarı Mustafa genotipleri hariç diğer genotipler dayanıklılık göstermiştir. -10 ve -15°C'de genotipler canlılıklarını tamamen kaybetmişlerdir. İkinci soğuk uygulama denemesinde soğuğa tolerans özelliği yönünden en iyi genotipler İsmetbey ve Refikbey, Üçüncü soğuk uygulama denemesinde ise soğuğa tolerans özelliği yönünden en iyi genotipler Sarı Mustafa ve Starlord genotipleri olmuştur. Tarla denemesinde ise bitki büyüme şekli yatık olan bitkilerin ise soğuk zararından az etkilendiği görülmektedir.The study was carried out in 5 stages. The germination experiment was set up in 3 repetitions with 11 genotypes and different temperature applications. Seedling height, root length, germination speed and germination power characteristics were determined. In the first cold application trial, cold damage measurements were determined as a criterion for cold resistance occurring during the seedling period in 11 genotypes. In the second cold application trial, 30 genotypes of Zadoks were established in the 23rd period by applying different cold applications. Cold damage measurement, vegetation temperature, chlorophyll rate, number of tillers in the plant, seedling height and stoma characteristics were examined. In the third cold application trial, 11 genotypes of Zadoks were established by applying different cold applications in the 31st period. Cold damage measurement, number of days to heading, waxiness, yield elements and sterility were determined. The field experiment was conducted with 11 genotypes in 5 replications with a planting density of 500 plants/m². In the study, plant growth pattern, number of days to heading, waxiness, grain yield and yield elements, and quality characteristics were examined. As a result of the variance analysis and significance test, it was observed that there was a significant change between genotypes in terms of cold applications and cold damage measurements. In the first cold application trial, all genotypes except Krasunia Odes'ka and Sarı Mustafa genotypes showed resistance at -5°C. At -10 and -15°C, genotypes completely lost their viability. In the second cold application trial, the best genotypes in terms of cold tolerance were İsmetbey and Refikbey, and in the third cold application trial, the best genotypes in terms of cold tolerance were Sarı Mustafa and Starlord genotypes. In the field trial, it was observed that plants with horizontal growth patterns were less affected by cold damage
Evaluation of Spirulina platensis as a Feed Additive in Low-Protein Diets of Broilers
No full textSpirulina platensis is a natural antioxidant product that has the ability to improve the performance of poultry. Therefore, the present study aimed to evaluate the effect of using Spirulina platensis as a feed additive in broiler diets. A total of 252 daily male Ross 308 chicks were randomly assigned to six groups. There were two different protein groups: one was at the catalog protein value, and the other was reduced by 10%. Spirulina platensis at 0, 0.1, and 0.2% was added to each protein group. The trial lasted 41 days. Reducing the protein level by 10% had a negative impact on the performance of the chicks. However, Spirulina platensis supplementation had a positive effect on the feed conversion ratio, reduced the oxidative stress index in the chicks' liver and meat, increased the total antioxidant status and antioxidant enzyme activities, improved the villus height, serum IgG, and some bone parameters, and reduced the serum triglyceride concentration. The carcass yield, visceral organ weight percentages, total phenolic content, and malondialdehyde (MDA) level in the thigh meat and some serum biochemical parameters were not affected by the usage of Spirulina platensis. In conclusion, 0.1% Spirulina platensis could be a feasible feed additive in low-protein diets due to eliciting an improved performance, antioxidant status, and immune response in broilers.Ankara University Scientific Research Projects; [21H0239001]Some part of this study was supported by Ankara University Scientific Research Projects (21H0239001)
