Adsorptive Performance of Magnetic Nano-Biosorbent for Binary Dyes and Investigation of Comparative Biosorption
(Springer Nature, 2019) Tarhan, T.; Tarhan, Tuba; Tural, B.; Boga, K.; Tural, S.; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
The individual and competitive biosorption capacities of Metanil Yellow (MY) and Reactive Black 5 (RB5) by glutaraldehyde cross-linked magnetic chitosan nanoparticles (GMCNs) were studied. Competitive biosorption of the MY and RB5 dyes by the GMCNs has never been reported previously. Fourier transform infrared technique has been used to show the biosorbed MY and RB5 dyes onto GMCNs. During the studies, various essential factors influencing the biosorption, like adsorbate concentration, pH of the solution and contact time have been monitored. The equilibrium was achieved within 17 h for single dyes and 3 h for binary mixture at pH 3. The biosorption capacities were 620 mg/g for dye MY and 2549 mg/g for dye RB5 at pH 3, 30 °C. The second-order kinetic model has good compatibility with the dynamical biosorption behavior of a single dye and binary mixture. In order to study the competition biosorption of the RB5 and MY dyes in mixture solutions, the intraparticle diffusion model was used. Competition biosorption through analysis of the intraparticle diffusion model apparently favored the RB5 dye more than the MY dye on the GMCNs in mixture solutions. The biosorbent was regenerated efficiently through the alkaline solution and was then reused ten times for biosorption–desorption cycles. © 2018, Springer Nature Switzerland AG.

(Scibulcom Ltd, 2015) Dogan, Y.; Doğan, Yusuf; Department of Plant Protection / Bitki Koruma Bölümü
Chickpea has significant amounts of all the essential amino acids except sulphur-containing types. It was found that chickpea is a rich source of protein and minerals. The experiments were conducted in a Randomised Complete Block Design with three replications 2013 and 2014 years in South-Eastern Turkey. A total of fifteen varieties, lines and populations were used as materials. In the study were investigated different parameters such as amino acids of protein, seed yield, protein and fat rate in seed, phosphorus, potassium, calcium, manganese, zinc, copper and iron contents and of seeds. The essential amino acid leucine (8.43 mg/100 g in 2013 and 8.59 mg/100 g in 2014) was found in highest concentration, followed by lysine (7.14 mg/100 g in 2013 and 7.27 mg/100 g in 2014) and phenylalanine (5.99 mg/100 g in 2013 and 6.07 mg/100 g in 2014) in the chickpea. Mineral composition of chickpea genotypes showed that they contribute sufficient amount of Ca, P, K, Cu, Zn and Mg in human diets to meet the recommended dietary allowance. According to the average of two years, the highest grain yield was obtained from Diyar-95 variety with 1618 kg ha(-1), the lowest grain yield was obtained from M-1 local population with 1104 kg ha(-1).
Ayvalık Tuzlasının Ağır Metal Düzeyinin Halimione Portulacoides (L.) Bitkisi Kullanılarak Belirlenmesi
(2019) Mungan Kılıç, Fatma; Ay, Güngör; Koçbaş, Fatma; Kılıç, Fatma Mungan; Department of Medical and Aromatic Plants / Tıbbi ve Aromatik Bitkiler Bölümü
Bu çalışmada, Ayvalık tuzlasında yayılış gösteren Halimione portulacoides (L.) Aellen bitkisi kullanılarak, tuzlanın Pb, Zn ve Cd düzeyleri Perkin Elmer Analyst 700 Model Alevli Atomik Absorbsiyon Spektrofotometresi (FAAS) cihazı kullanılarak belirlenmiştir. Tuzla İzmir-Çanakkale karayolunun bitişiğinde yer aldığından dolayı ayrıca karayoluna olan mesafeye bağlı değişimlerde belirlenmiştir. Bitkinin kök, gövde ve yaprak kısımları ile onun yetişme toprağı çalışmanın materyalini oluşturmuştur. Örneklemeler 2009-2010 yılları arasında, tuzlayı çevreleyen toprak set üzerinde belirlenen yedi istasyonda yapılmıştır. Her istasyondan 12 ay boyunca düzenli olarak numuneler alınmıştır. Yapılan tüm analizler sonucunda bitkide; Pb <0.001-0.977 ppm, Zn 0.099-1.650 ppm, Cd <0.001-0.102 ppm, toprakta ise Pb 0.523- 1.599 ppm, Zn 0.143-1.248 ppm ve Cd 0.006-0.432 ppm arasında olduğu belirlenmiştir. Pb ve Zn birikimi yola olan mesafeye bağlı artmış, Cd birikimi ile yola olan mesafe arasında ise net bir ilişki elde edilememiştir. Analizlerde sonuçların sınır değerlerin altında olmasının en önemli nedeni, hakim rüzgâr yönünün kuzeybatı (tuzladan karayoluna doğru) olması, tuzlanın güneyi boyunca uzanan karayolu üzerinde herhangi bir kavşak ve sinyalizasyonun bulunmaması ve yakınında kirletici özelliği olabilecek endüstri ve sanayi tesislerinin olmamasıdır.

Cardioprotectiveeffectsof Hypericumtriquetrifoliumturra. Against Cyclophosphamide Related Cardiotoxicity in Rats
(2018) Çetik Yıldız, Songül; Keskin, Cumali; Ayhanci, Adnan; Şahintürk, Varol; Yıldız, Songul Cetık; Keskin, Cumali; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
Cyclophosphamide (CYP) is commonly used as anticancer agent but its usage is limited by cardiotoxic side effects such as dose-dependent cardiac damage, morphologically defined necrosis and bleeding. Hypericum triquetrifoliumTurra. (HT) shows anti-oxidative and anticarciogenic properties with its rich phenolic contents. The current study was designed to investigate the possible protective effect of HT on CYP-induced cardiotoxicity. Albino ratswererandomlydividedinto9groups,eachincluded7animals.Serumcreatinekinase-MB(CK-MB), malondialdehyde (MDA), aspartate transaminase (AST), glutathione (GSH), total antioxidant (TAC) and total oxidant capacity (TOC) levels were investigated. Furthermore, the cardiac tissue samples were investigated histopatologically. While the levels of serum CK-MB, MDA, AST and TOC were high, the levels of serum GSH and TAC levels were low in the CYP groups. It was also observed that CYP-induced cardiotoxicity was dose dependent. In the treatment with CYP plus HT doses there was observed an essential decrease in the CYP cardiotoxicity; decreased cell damage and oxidative stress parameters and also increased GSH and TAC levels. Based on our findings, it can be proposed that HT seed methanol extract was a strong candidate in preventing the CYP-induced cardiotoxicity.

Comparison Of Different Life Stages Of Total, Phospholipid And Triacylglycerol Fatty Acids Of Lucilia Sericata
(ABADER (Adıyaman Bilimsel Arastırmalar Dernegi), 2021) Kızmaz, Veysi; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
Lucilia sericata, which belongs to the Calliphoridae family (Diptera), is used as a debridement tool in open necrotic wounds that do not respond to conventional treatments. Knowing the total, phospholipid (PL), and triacylglycerol (TAG) fatty acid content of L. sericata fly, which is important for health, in its different stages is important both in terms of taxonomy and physiology. After L. sericata samples used in the study were obtained commercially, they were bred under laboratory conditions and then the fatty acids in different stages were analyzed by gas chromatography. Sixteen fatty acids are determined as a result of the analysis. When individual fatty acids are considered, Palmitic acid (16:0), Palmitoleic Acid (16:1n-7), oleic acid (18:1n-9) and Linoleic Acid (18:2n-6) were found to be major ones, while the others are detected in trace amounts. It is determined that, out of total, PL and TAG, saturated fatty acids (SFA) are found at a high percentage in the eggs, monounsaturated fatty acids (MUFA) are the highest in the larvae, and polyunsaturated fatty acids (PUFA) are the highest in fly and pupa. Furthermore, out of total, PL and TAG, ∑PUFA is at a low percentage in the egg and the larval stages. Different results are found at different stages in this study. This may be because fatty acid percentages that change during metamorphosis meet different physiological needs at different phases. © 2021, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).

Lentil (Lens culinaris Medic.) is an important food crop with high protein content. This study aimed to determine the effects of increasing doses of phosphorus and humic acid applications on P, K, Ca, Mg, Fe, Cu, Mn, Zn, protein ratio and seed yield in lentil cultivar. The study was carried out in the research and application during the 2008–2009 and 2009–2010 cropping seasons in field of Agriculture Faculty Yuzuncu Yil University, Turkey. The experiment comprised a factorial randomised complete block design replicated three times with three phosphorus treatments 0, 40 and 80 kg ha–1, as triple superphosphate, and three humic acid treatments 0, 300 and 600 kg ha–1. For basic fertilisation 40 kg ha–1 ammonium sulphate were applied for nitrogen. The nutrient contents of seed and yield were significantly increased by increasing phosphorus and humic acid levels except for Zn content nutrient. The combination between phosphorus at 80 kg P2O5 ha–1 and humic acid at 600 kg ha–1 gave the highest growth and production as well as minerals composition (P, K, Ca, Mg, Fe, Cu and Mn) and protein content compared to other treatments. Humic acid increased the availability of phosphors, macronutrients and micronutrients. © 2016, Scibulcom Ltd. All rights reserved.

Energy Consumption of Defrosting Process in No-Frost Refrigerators
(Yildiz Technical University, 2018) Ünal, Fatih; Ünal, F.; Department of Machine and Metal Technologies / Makine ve Metal Teknolojileri Bölümü
Refrigerators have high energy consumption because they consume energy throughout the day, and they are used in all residences and in most offices. Designing more efficient models and, thus, decreasing the energy consumption of refrigerators have become necessary, owing to the global energy scarcity. The purpose of this study was to decrease energy consumption and increase the efficiency of the defrosting process in no-frost refrigerators. The defrosting process plays an important role in the energy consumption of no-frost refrigerators. The amount of energy needed for defrosting and the time it takes are important factors for manufacturers in terms of energy performance. Recently, a theoretical correlation was developed as a function of the frost thickness, heat flux, and frost density for estimating the defrosting time of an evaporator fin surface. The melting time of the frost on the fin was calculated by a mathematical model and compared to results that were obtained experimentally. The results were differed from the actual melting time as 4.7%. © 2018 Yildiz Technical University.

The uniformity of genotypes are significant for crop breeding program decisions to improve new varieties. The AMMI (Additive main effects and multiplicative interaction) analysis and Genotype x Environment Interaction (GEI) is make to estimation grain yield and understands GxE interaction patterns by researches as differential ranking of variety yields in multi-environment trials. Therefore, fifteen barley advanced line and six national cultivars and four foreign varieties (registered in abroad) were used in the study. The experiments were performed according to a complete randomized block design with four replications at five environments during two years. The stability and superiority of genotypes for yield and other traits were determined using AMMI and GGE biplot analysis. Factors (G, GE, and GEI) were found to be highly significant (P < 0.01) for grain yield. AMMI analysis indicated that the major contributions to treatment sum of squares were environments (98.52%), GE (0.45%) and genotypes (1.02%), respectively, suggesting that grain yield of genotypes were effected environmental conditions. The GGE biplot indicated that PCA 1 axes (Principal component) was significant as P<0.01 and supplied to 49.36% of complete GxE interaction. The AMMI indicated that G8 and G23 desirable and stabile genotypes for grain yield in multi-environment. Moreover, E2 and E5 (irrigated environments) were high yielding, while E3 (drought stress) low yielding as forecast. On the other hand, GGE biplot indicated that three group were occurred among traits, first group (GY: grain yield, CC: crude cellulose, CD: cold damage), second group (PC:, HVV: hectoliter weight, TGW: thousand grain weight, SH: seed humidity), third group (LOD: lodging, PH: plant height, HT: heading time). Moreover: the study showed that G3, G6, G7, G8, G13 and G21 were the best genotypes both grain yield and other traits. The results of AMMI model and GGE biplot indicated that G8 is suitable to recommend for release and G23 desirable origin for yield stability and G7 valuable source for quality to use in barley breeding program.

(Parlar Scientific Publications (p S P), 2020) Kizilgeci, Ferhat; Kızılgeçi, Ferhat; Mokhtari, Negar Ebrahim Pour; Hossain, Akbar; Department of Seed Production / Tohumculuk Teknolojisi Bölümü
Turgor maintenance through osmotic adjustment can play a vital role in plant tolerance to drought and salinity. As per the evidence of the previous study, chemical polyethylene glycol (PEG) can create physiological drought under both salinity and water deficit conditions. Therefore, PEG is used for forcefully create osmotic stress to find out drought and salinity resistant crop cultivars at the early stage. Considering the essential role of PEG, the current observation was undertaken for understanding the effects of drought and salinity stress on several bread wheat genotypes at early developmental stage particularly during the seedling stage. Five bread wheat genotypes including four varieties such as 'Tekirdag', 'Ceyhan 99', 'Dine', 'Empire Plus' and a line 'DZ17-1' were used as seed material. To find out the genotypes which are tolerant to drought and salinity, all wheat genotypes were evaluated in four different concentration of NaCI for salinity stress (i.e., 0, 4, 8 and 12 dS/m) and four different concentration of PEG 6000 (i.e., 0, -0.2, -0.4, -0.6 MPa) for drought stress. All treatments were organised in a completely randomized design (CRD) and repeated three times. After observation, it is revealed that bread wheat cultivars 'Dine' and 'Ceyhan 99' were found tolerant of both drought and salinity stress at the seedling stage. The study also noticed that understanding of seedlings growth such as mean germination time (MGT), coleoptile length, seedling height, root length and relative water content (RWC) allow the selection of genotypes tolerance to drought and salinity. The information from the study will be helpful for examination of wheat genotypes which are suitable to cultivate under osmotic stress of both drought and salinity stress condition.

The aim of the study was to determine the structure of GEI in the investigated parameters and to investigate the performance stability of durum wheat varieties using the GGE biplot and AMMI analysis method. The study was carried out in four different locations (Diyarbak & imath;r-1, Diyarbak & imath;r-2, Hatay, and & Scedil;anl & imath;urfa) using 31 durum wheat genotypes under rainfed conditions. Field experiments were conducted in a randomized complete block design with three replications. As a result of the study, it was determined that there was a significant difference between locations in terms of grain yield. The highest grain yield was obtained from Diyarbak & imath;r-1 (6797 kg ha-1) location, followed by Hatay (4584 kg ha-1), Diyarbak & imath;r-2 (2512 kg ha-1) and & Scedil;anl & imath;urfa (2026 kg ha-1), respectively. Significant variations in grain yield were detected among the examined genotypes, and Artuklu and Z & uuml;hre had the highest grain yields (4774 and 4501 kg ha-1). Again, Artuklu and Z & uuml;hre were the most stable varieties in terms of their performance in different locations. Diyarbak & imath;r-1 has come to the fore as the location where the variation between genotypes can be best detected. As a result, more data should be provided to plant breeders in the selection studies by considering the irrigated conditions as a factor in the studies to be carried out and determining the stable cultivars in terms of grain yield in both precipitation-based and irrigated conditions.

Neoscytalidium dimidiatum: A newly identified postharvest pathogen of pears and its implications for pome fruits
(Wiley, 2024) Derviş, Sibel; Zholdoshbekova, Sezim; Guney, Inci Guler; Ozer, Goksel; Department of Organic Agriculture / Organik Tarım Bölümü
T & uuml;rkiye is a prominent contributor to pear and diverse pome fruit production. Pear fruit with unusual brown to black spots and rot symptoms observed in public marketplaces in Mardin province have raised concerns regarding postharvest fruit health. The consistent isolation of a fungus from these fruits revealed morphological features indicative of Neoscytalidium dimidiatum. Phylogenetic confirmation of its identity ensued through BLASTn searches targeting, the internal transcribed spacer (ITS) of ribosomal DNA, the partial translation elongation factor 1-alpha gene (tef1), and the partial beta-tubulin gene (tub2). Pathogenicity evaluations were conducted on common pome fruits, namely pears, apples, and quinces, unveiling the susceptibility of all examined fruits to postharvest infection by this emergent pathogen. Furthermore, an investigation was carried out to discern the pathogen's response to varying temperature ranges on pear fruits, revealing that the most pronounced lesions occurred at 30 degrees C, followed by 25 degrees C, 35 degrees C, and 20 degrees C. Conversely, no lesion development was observed at 10 degrees C, 15 degrees C, or 40 degrees C. To the best of our knowledge, this study represents the first report of N. dimidiatum as the etiological agent responsible for postharvest rot in pear fruit. The implications of these findings highlight the potential threat posed by this pathogen to pome fruits postharvest, especially in regions where cold storage facilities are not widely utilized, warranting increased vigilance and preventive measures.

Synthesis and Characterization of Boron Nitride Nanotubes (Bnnts) With a New Method and Precursor Materials
(Gumushane University, 2021) Tarhan, T.; Tarhan, Tuba; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
Boron nitride nanotubes (BNNTs) have many application areas thanks to their superior properties such as thermal and electrical insulation, resistance to oxidation, high hydrophobicity, and high hydrogen storage capacity, as well as biocompatible properties. Therefore, new synthesis methods are being searched for BNNT with increasing interest in recent years. In this study, high purity and yield BNNTs were synthesized using precursor materials and methods that were not previously tried in the literature. A chemical vapor storage (CVD) furnace was used for the synthesis, and various parameters were changed to achieve optimum conditions. The structure of the obtained BNNTs was characterized by Fourier conversion infrared spectroscopy (FTIR), Raman spectroscopy, and a UV-visible spectrophotometer. In addition, surface morphologies were illuminated using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). However, it has been observed that BNNTs obtained as a result of HR-TEM (high-resolution transmission electron microscope) analysis have a single-walled structure that is difficult to synthesize. This increases the importance and quality of synthesized BNNTs. © 2021, Gumushane University. All rights reserved.
