Effects of different irrigation practices using treated wastewater on tomato yields, quality, water productivity, and soil and fruit mineral contents
No full textWastewater use in agricultural irrigation is becoming a common practice in order to meet the rising water demands in arid and semi-arid regions. The study was conducted to determine the effects of the full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation practices using treated municipal wastewater (TWW) and freshwater (FW) on tomato yield, water use, fruit quality, and soil and fruit heavy metal concentrations. The TWW significantly increased marketable yield compared to the FW, as well as decreased water consumption. Therefore, water use efficiency (WUE) in the TWW was significantly higher than in the FW. Although the DI and the PRD practices caused less yields, these practices significantly increased WUE values due to less irrigation water applied. The water-yield linear relationships were statistically significant. TWW significantly increased titratable acidity and vitamin C contents. Reduced irrigation provided significantly lower titratable acidity, vitamin C, and lycopene contents. TWW increased the surface soil and fruit mineral contents in response to FW. Greater increases were observed under FI, and mineral contents declined with reduction in irrigation water. Heavy metal accumulation in soils was within safe limits. However, Cd and Pb contents in fruits exceeded standard limits given by FAO/WHO. Higher metal pollution index values determined for fruits also indicated that TWW application, especially under FI, might cause health risks in long term
THE EFFECT OF DIFFERENT IRRIGATION APPLICATIONS ON THE BLOSSOM-END ROT IN TREATED WASTEWATER-IRRIGATED TOMATOES (LYCOPERSICON ESCULENTUM)
No full textThe study investigates the effect of water deficit conditions on blossom-end rot (BER) in tomato. Drip irrigation was used in irrigation. Therefore, experiment was conducted as a randomized complete block design (three replicates), in a 2 x 5 factorial arrangement, corresponding to two different water resources [treated wastewater (TWW) and freshwater (FW)] and five different irrigation practices. The irrigation strategies comprised full irrigation (100%), deficit irrigation, which involves the use of 75% and 50% of the water used in full irrigation, and partial root drying (PRD). According to the study results, in the full irrigation applications, blossom-end rot according to the fruit number values were 10.85% in fresh water irrigation while it was the lowest with 8.57% for treated wastewater. Also, in full irrigation applications, blossom-end rot values according to fruit weight were found to be lower compared to those in other applications. It was determined that there was a negative relation between blossom-end rot and Ca value. The lowest blossom-end rot incidence was observed in the full irrigation applications, while it was lower in the PRD applications than in the D applications. In the production of marketable tomato, the PRD applications can be more advantageous than the D applications under water shortage conditions
AN EVALUATION OF WATER QUALITY IN MICRO-CATCHMENTS WITH HIGH EROSION RISK WITH CCME WATER QUALITY INDEX: CASE OF CAPAKÇUR MICROCATCHMENT
No full textA significant portion of the world's freshwater resources is allocated to agricultural irrigation. However, these waters are increasingly polluted due to various environmental factors. This pollution subsequently leads to soil contamination through irrigation and the degradation of specific productivity characteristics. As a result, monitoring water resources has become a critical global concern. In this study, we evaluated the water quality of the & Ccedil;apak & ccedil;ur Stream, an essential water source for the Bing & ouml;l Plain, using the Water Quality Index (WQI) developed by the Canadian Council of Ministers of the Environment (CCME). Monthly samples were collected from six different locations throughout 2019. Subsequently, 22 physicochemical parameters related to water quality were analyzed. The analysis indicated that the lowest water quality index values for the & Ccedil;apak & ccedil;ur Stream occurred in July in the monthly assessment and during the spring season. In contrast, the highest water quality index was recorded in January, both monthly and during summer. Notably, all obtained results were classified as marginal according to the WQI classification. The index values ranged from 50 to 54 according to the seasons, 49 to 56 according to the months, and 48 to 56 according to the sampling points. Consistent results (52) were observed during both dry and wet precipitation periods. These findings emphasize the urgent need for a cautious approach in using this water resource for irrigation, alongside the importance of regular monitoring and periodic analyses to maintain its quality

No full textURL:http://sefad.selcuk.edu.tr/sefad/article/view/129Juan Goytisolo Çagdas spanyol Edebiyatı’nın en önemli yazarlarından birisidir. Yazar sadece içinde yetistigi Batı kültürünü degil, Dogu dünyasını da çok iyi bilmekte ve romanlarında her iki kültürün unsurlarını kullanmaktadır. Bu bakıs açısından hareketle burada yayımlanan makalenin temel amacı yazarın Kırk Günlük Süre adlı romanında Hıristiyanlık ve Müslümanlık unsurlarını ele alarak Batı ve Dogu kültürlerini incelemektir. spanya ç Savası’ndan (1936-1939) kısa bir süre önce 1931 yılında Barselona’da dogan Goytisolo, iç savas sırasında çocuklugunu yasamıs, talihsiz 30’lar kusagı yazarlarındandır. Yazar iç savas sonrası baslayan General Franco’nun Hıristiyanlıktan baska dinlere ve kültürlere karsı katı ve hosgörüsüz olan diktatörlügü döneminde gençlik yıllarını geçirmis ve bu nedenle 1956 yılında kesin olarak Paris’e yerlesmistir. Burada yazar buldugu özgürlük ortamıyla farklı din ve kültürlerle de ilgilenmeye baslamıstır. Dogu kültürü ile tanısması Cezayir olayları nedeniyle olmustur. Cezayir bagımsızlık savası sırasında Fransız hükümetinin ve aydınlarının gösterdikleri davranıslardan dolayı yazar hayal kırıklıgına ugramıstır. Fransa’da yasayan birçok Afrika kökenli kisinin polis tarafından tutuklanması yazarın Avrupa’ya ve içinde bulundugu kültüre karsı bakıs açısının degismesine ve Dogu felsefesini ve kültürünü incelemesine neden olmustur. slamiyet’in Batı dünyasında yanlıs anlasıldıgını düsünen Goytisolo slam kültürü ilgili birçok yazı yazmıs ve romanlarında sadece Hıristiyanlık ögelerini degil slam kültürünün unsurlarını da kullanmıstır. Her iki kültürü birlikte kullandıgı yapıtlarından birisi de 1991 yılında yayımlanan Kırk Günlük Süre’dir. Dante’nin Hıristiyan dünyası için en önemli eserlerden biri olan 0lahi Komedya’dan etkilenen yazar eserinde slâmiyet’te yer alan berzah âlemini anlatmaktadır. Roman bir baska yönden bakıldıgında politik unsurları da barındırmaktadır. Güncel konuları yakından takip eden ve bu konuları romanlarında kullanan yazar romanın yazıldıgı dönemde meydana gelen Körfez Savası’na din olgusu çerçevesinde deginmis ve bu savasın sonuçlarına da kitabında yer vermistir. Bu baglamda yazar Batı dünyasının bu savas üzerindeki etkilerini de ortaya koymus ve Batı’nın Dogu cografyasına yaptıgı siyasi müdahaleyi elestirmistir.Juan Goytisolo is one of the most important authors of Spanish contemporary literature. The author does not know very well only the elements of Western culture but also Eastern world and he uses in his novels the elements of both cultures. Based on this, the main purpose of this essay that published is to study Eastern and Western cultures in Quarantine novel by the way of the Christian and Islamic elements. Born in Barcelona before a short time of the Civil War (1936-1939), Goytisolo is one of the authors of unlucky generation of the 30s, spending their childhood in times of the Civil War. He passed his youth in the period of the religious and cultural intolerance of the dictatorship of General Franco, starting after the Civil War and for this reason settled definitely in Paris. In Paris, the author started to get interested in different religions and cultures due to the atmosphere of freedom. The events in Algeria caused him to get to know the Eastern culture. Through the Algerian War of Independence the author got disappointed because of the behavior of the French government and intellectuals. The detention of many Africans by the police in France led to a change of the perspective of the writer about Europe and its culture caused the author to search about the Eastern philosophy and culture. Believing in the misunderstanding of Islam in the Western world, Goytisolo has written a lot of works in relation to the Islamic culture. He includes in his novels the elements of Christianity as well as the features of Islamic culture. One of these books in which he uses both cultures is the Quarantine novel published in 1991. The author impressed by Divine Comedy, which is one of the most important books for the Christian world, describes in the novel barzakh exiting in Islamic eschatology. Goytisolo succeeds in combining Western and Eastern cultures in the same book in this way. Seen from another perspective, the novel also holds political issues. The author who follows the global issues and uses them in his novels, mentions the Gulf War and the results of this war, happening at the time of writing the novel. In this context, the writer divulges the effects of the Western world on this war and criticizes its political intervention on the Eastern geography

No full textDoğan, Fırat (Dogus Author) -- Conference full title: 15th National Biomedical Engineering Meeting (BIYOMUT), Akdeniz University, Antalya, 21-24 April.Yumuşak dokuların belirli sınır koşulları ve kuvvetler altındaki davranışlarının modellenmesi sanal ameliyat uygulamaları, kan akışı simülasyonları, implant operasyonları gibi birçok medikal ve mühendislik alanında ihtiyaç duyulan araştırma alanlarındandır. Farklı fiziksel koşullardaki bu doku davranışlarının ve şekil değiştirmelerin hatasız bir biçimde elde edilmesi ileri sürülen modelin matematiksel gücü ve modelde kullanılan malzeme katsayılarının doğru belirlenmesi ile orantılıdır. Önerilen her yeni yöntem, model ve malzeme katsayıları belirleme çalışmalarının, doğrulanması böylece uygulanan yöntemin avantaj ve dezavantajlarının ortaya konulması önemli bir gereksinimdir. Yönden bağımsız, homojen yapıları ve yapılan deneylerin aynı yük ve sınır şartları altında tekrar edilebilme avantajları nedeniyle yapay malzemeler üzerinde yapılan laboratuar deneyleri önerilen modellerin doğrulanma aşamalarında bir takım fiziksel standartların oluşturulmasında katkılar sağlayacaktır. Bu çalışmada insan karaciğerine çok yakın malzeme özelliklerine sahip viskoelastik silikon üzerinde yapılan indentasyon deney sonuçları sunulmuştur. Deney sonuçları geometrik yapısı ve sınır şartları belirli bir yapının yük altındaki davranışını tam olarak göstermesi avantajı ile bu alandaki uygulamaların örneğin gerçek zamanlı çalışan sanal ameliyat simülatörü, sonlu elemanlar yada kütle-yay sistemi modellerinden elde edilen sonuçların doğrulanması için kullanılabilecek verileri sağlamaktadır.The modeling of deformation behavior of soft tissues under known boundary conditions and forces is fruitful research in engineering and biomedical area that is found in various applications such as virtual surgery, blood flow simulation, implant operations etc. Accurate modeling of this tissue deformation bahaviour is proportianal to the mathematical power of the proposed model and the accurate determination of the material coefficients that are used in the model to feature material properties. Verification of each newly proposed method, model and coefficients, thus, displaying the advantages and disadvantages is an important necessity. Laboratory experiments which are done on artificial materials, when their isotropic and homogenous structures and the advantage to be able to repeat the experiments under the constant conditions such as same load and same boundary are considered, will contribute to the development of some physical standarts for the verification process of the proposed models. In this study, the results of an indentation experiment made on an viscoelastic silicon material of which material properties are very close to that of human liver are presented. These results make the data that can be used to confirm the results gathered from the applications of the related area such as real-time virtual surgery simulators, finite element or massspring system models, providing the fact that the experiments display the exact behaviour of the structure that has invariable geometry and boundary conditions
Evaluation of autonomic nervous system function in children with overactive bladder syndrome
No full textMotor skills, language development, and visual processing in preterm and full-term infants
No full textLanguage development is intertwined with motor development. This study examined how visual processing might mediate the relation between language development and motor skills in preterm (PT, n = 34, Mean gestational age = 30 weeks) and full-term infants (FT, n = 35, Mean gestational age = 38.9 weeks) at 13 months of age. Infants' visual processing, fine and gross motor skills were tested using the Mullen Scales of Early Learning. Parents reported on infants' language skills (word comprehension and early communicative behavior), using the Turkish version of CDI (TCDI). Results showed that PT infants performed worse than their FT peers on gross motor skills and visual processing, but not on language. When controlling for age and neonatal condition (being preterm or not), visual processing mediated the relation between gross motor skills and word comprehension as well as early communicative behavior. However, for fine motor skills, visual processing mediated the relation between fine motor skills and early communicative behavior but not word comprehension. The relations between motor skills and visual processing were more robust for the PT group than the FT group. Following developmental cascades, these findings suggest that motor skills contribute to language development through visual processing. These relations are prominent for preterm infants who have delays in motor skills. PT children's limited interactions with their environment due to problems in motor skills can be connected to delays in visual processing.James S.

Clinical and laboratory aspects of patients diagnosed with various inherited platelet disorders
No full textBackground: Inherited platelet disorders (IPDs) are characterized by thrombocytopenia, platelet dysfunction, or both, leading to recurrent bleeding and diagnostic challenges. Advances in genetic testing have significantly improved early and accurate diagnoses. Objectives: This study aimed to evaluate the clinical and genetic spectrum of IPDs, identify diagnostic challenges, and assess outcomes of therapeutic interventions. Methods: We conducted a retrospective cohort study of 50 IPD patients. We performed clinical evaluations, peripheral smear analyses, and genetic testing to identify causative variants. Correlation between platelet counts, bleeding severity, and the effectiveness of treatments, such as hematopoietic stem cell transplantation and thrombopoietin receptor agonists, was analyzed. Results: A total of 54.5% of cases showed autosomal dominant inheritance. Diagnostic delays were common, with many patients initially misdiagnosed as having immune thrombocytopenic purpura (ITP). There was a moderate, negative, statistically significant correlation between platelet counts and bleeding severity. Peripheral smear findings, such as stomatocytosis and macrothrombocytopenia, provided critical diagnostic clues. We identified novel mutations in GP1BA, ITGB3, NBEAL2, WAS, and MPL genes, which expanded our understanding of IPDs. Different treatment modalities were used. Hematopoietic stem cell transplantation was performed in severe systemic cases, such as Wiskott–Aldrich syndrome. Sitosterolemia was treated with ezetimibe. Thrombopoietin receptor agonists reduced bleeding in some patients. Conclusion: Integrating genetic, clinical, and laboratory findings is essential in providing accurate diagnoses and management of IPDs. Early genetic diagnosis and personalized therapeutic strategies improve outcomes. Future research should focus on functional studies of novel mutations and refining treatment protocols to enhance care for this complex population. © 2025 The Author(s
Nationwide prospective audit for the evaluation of appendicitis risk prediction models in adults: Right iliac fossa treatment (RIFT) - Turkey
No full textBackground: Appendicitis is the most prevalent surgical emergency. The negative appendicectomy rate and diagnostic uncertainty are important concerns. This study aimed to assess the effectiveness of current appendicitis risk prediction models in patients with acute right iliac fossa pain. Methods: A nationwide prospective observational study was conducted, including all consecutive adult patients who presented with right iliac fossa pain. Diagnostic, clinical and negative appendicectomy rate data were recorded. The Alvarado score, Appendicitis Inflammatory Response (AIR), Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and Adult Appendicitis Score systems were calculated with collected data to classify patients into risk categories. Diagnostic value and categorization performance were evaluated, with use of risk category-based metrics including 'true positive rate' (percentage of appendicitis patients in the highest risk category), 'failure rate' (percentage of patients with appendicitis in the lowest risk category) and 'categorization resolution' (true positive rate/failure rate). Results: A total of 3358 patients from 84 centres were included. Female patients were less likely to undergo surgery than men (71.5% versus 82.5% respectively; relative risk 0.866, 95% c.i. 0.834 to 0.901, P 0.001); with a three-fold higher negative appendicectomy rate (11.3% versus 4.1% respectively; relative risk 2.744, 95% c.i. 2.047 to 3.677, P 0.001). Ultrasonography was utilized in 56.8% and computed tomography in 75.2% of all patients. The Adult Appendicitis Score had the best diagnostic performance for the whole population; however, only RIPASA was significant in men. All scoring systems were successful in females patients, but Adult Appendicitis Score had the highest area under the receiver operating characteristic curve value. The RIPASA and the Adult Appendicitis Score had the best categorization resolution values, complemented by their exceedingly low failure rates in both male and female patients. Alvarado and AIR had extremely high failure rates in men. Conclusion: The negative appendicectomy rate was low overall, but women had an almost three-fold higher negative appendicectomy rate despite lower likelihood to undergo surgery. The overuse of imaging tests, best exemplified by the 75.2% frequency of patients undergoing computed tomography, may lead to increased costs. Risk-scoring systems such as RIPASA and Adult Appendicitis Score appear to be superior to Alvarado and AIR. © 2024 The Author(s).
