Characterization of bean (Phaseolus vulgaris L.) cultivars grown in turkey by SDS-page of seed proteins

In the present research, a total 28 bean cultivars grown in Turkey were characterized by the numerical analysis of seed protein profiles obtained by using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) technique. The numerical analysis of seed protein profiles generated two major clusters at similarity levels of 82.52% or above. The first cluster included 5 reference bean cultivars at the intra-cluster similarity values of 91.25% or above. The second cluster comprised the all remaining genotypes at similarity values between 84.46% and 100%. Our results also indicated that Gina standard cultivar together with all eastern genotypes belonged to subcluster IIc, having the highest intra-cluster similarities between 95.54% and 100%. In this sense, it is suggested that probably there may be a very close genetic relationship between eastern genotypes and Gina cultivar. In conclusion, this study indicated that the numerical analysis of seed protein profiles offer no final answer to the identity of bean genotypes, however, the method can provide of extra banding pattern for the discrimination of bean genotypes cultivated in Turkey

Determination of the Relationship Between Seed and Seedling Leaf Characteristics and Salt Tolerance in Watermelon [Citrullus lanatus (Thunb.) Mansf.] Genotypes

In order to determine the relationships between salt tolerance, seed and seedling characteristics, 16 watermelon genotypes collected from various regions of Turkey, and 3 standard and 2 F1 hybrid varieties were used as material in the study. The seedlings were grown in Hoaglands nutrient solution in aqua culture in an atmospheric controlled climatic environment, and 100 mM NaCl salt stress was applied when the seedlings had 4-5 true leaves,. It has been understood that watermelon genotypes have different responses to salt stress in seedling growth and ion uptake. The watermelon genotypes 18, 22, 28, 31 and 41, with large seed weights and large cotyledon leaves were less affected from salt damage by being more selective in ion uptake. Watermelon genotypes 33, 38, 39, 40 and 44 with low seed weights and cotyledon leaf weights were not selective on ion uptake and were more affected by salt damage. It has been observed that the parameters used in the study have a high correlation with each other

Capacitive micromachined ultrasonic transducer: transmission performance evaluation under different driving parameters and membrane stress for underwater imaging applications

Transmission performance of a CMUT element in terms of output pressure and displacements was evaluated. A SIMULINK model of single CMUT element based on mechanical model of MEMS capacitor was used and the analyses were performed under different ac and dc conditions. 2.6 µm thick Si, Poly-Si and Si3Ni4 membranes with a radius 60 µm were used to obtain results for underwater imaging application. Relation between membrane stress and outputs of CMUT was also investigated using SIMULINK model for commonly used CMUT membrane made of Si3Ni4 and polysilicon membrane under different electrical driving parameters. It was observed that different ac signal inputs (sine, square and sawtooth) showed different effects on CMUTs pressure and displacement characteristics. Our results indicated that the maximum output pressure and displacement were obtained in a square waveform. In addition, although stress on membrane increases the displacement and pressure of CMUT membrane made of Poly-Si, quality factor inversely proportional to stress on membrane. Membrane stress has adverse effect on Si3Ni4 membrane transmission outputs. The used model in this study might enable to determine optimum driving electrical inputs and stress on membrane to control CMUT outputs in terms of output pressure, displacement, quality factor and bandwitdh

Gemi Büyüklüğü ve Yaşının İşletme Maliyetleri Üzerine Etkisi: Dökme Yük Gemileri Üzerine Bir Uygulama

Düzensiz hat taşımacılığı olarak da adlandırılan tramp denizyolu taşımacılığında ağırlıklı yükler olarak dökme yük gemileri tarafından taşınmaktadır. Denizyolu taşımacılığının bu biçiminde, tam rekabet piyasası şartları hüküm sürdüğünden navlun fiyatı da arz ve talebe göre belirlenmektedir. Dolayısıyla denizyolu taşıma firmalarının kontrolü dahilinde olmayan navlun fiyatlarındaki belirsizliklere karşı pozisyon ayarlamak isteyen sektör işletmeleri maliyet odaklı bir yönetim anlayışı belirlemek durumundadır. Bu çalışmada gemi büyüklüğü ve yaşının, denizyolu taşma maliyetlerinin bir bileşeni olan işletme (running costs) maliyetleri üzerindeki etkileri araştırılarak maliyet tasarrufu yapılabilmesi adına fikir sunulmaya çalışılmıştır. Elde edilen sonuçlar göstermiştir ki, geminin yaşı arttıkça günlük işletme maliyetleri artmakta olup belli kısıtlar içerisinde gemi yaşı sabit tutulduğunda ve gemi büyüklüğü arttıkça personel giderlerinin azalmaktadır (R2 = 0,97, F=83,61, p<0,01)

Brassica oleracea türlerinde sıcaklık şoku uygulamalarının mikrospor embriyogenesis üzerine etkisi

Heat shock treatments are widely used to induce microspore embryogenesis in Brassica species. In this study, the effect of high temperature treatment (32 °C and 35 °C for 2 days) on microspore embryogenesis was investigated in six genotypes of Turkish white head cabbage (Yalova-1, Ercis, 177 C, 177 T, 531 C, 538 C), three genotypes of Turkish kale (Balkaya, Yanmaz, Karadere 077) and five commercial F1 ornamental kale hybrids (Red Piegon, Victoria Piegon, Red Chidori, white Kamome, and Pink Kamome). Microspore-derived embryos formation differed depending on genotype and high temperature. The highest embryo yield was obtained as 9.92 embryo per petri dish in cv. Yalova-1, 11.13 embryo per petri dish in Pink Kamome F1 at 32 °C, and 5.63 embryo per petri dish in cv. Karadere 077 at 35 °C.Yüzüncü Yıl University Scientific Research Project Council (YYU BAP, Project No: 2011-ZF-B005
