Organik Patates Yetiştiriciliği Üzerinde Araştırmalar

Samsun-Ladik’de iki yıl (2005 ve 2006) süresince yürütülen bu çalışmada bitkisel materyal olarak organik üretim için önerilen Sante çeşidi kullanılmıştır. Çalışmada kontrol (gübresiz), ahır gübresi (1 ton/da), çeltik kavuzu (100 kg/da), ahır gübresi+çeltik kavuzu( 1 ton/da+100 kg/da), biofarm (250 kg/da) ve inorganik gübre (NPK, 15:5:20 kg/da) olmak üzere altı uygulama denenmiştir. Patates böceği ile mücadelede azadractin kullanılmış olup, etkili sonuç alınmıştır. Organik parsellerde 1.sınıf verim ve toplam verim NPK uygulamasına göre daha düşük olmuştur. Ortalama değerlere göre yumru iriliği ve bitki başına düşen ortalama yumru sayısı organik parsellerde NPK uygulamasına göre daha düşük bulunmuştur. Yumrunun kuru madde miktarı ve özgül ağırlık değerleri bakımından organik ve geleneksel yöntem arasında farklılık belirlenmemiştir. Buna karşın yumrunun kül ve protein miktarı bakımından uygulamalar arasında önemli farklılıklar belirlenmiştir. En fazla kül içeriği kontrolden (%6.08) elde edilmiş olup, diğer uygulamalar aynı grup içerisinde yer almıştır. Ortalama değerler dikkate alındığında en fazla protein içeriği NPK uygulamasından (%9.26), en düşük ise ahır gübresi uygulamasından (%7.25) elde edilmiştir

The Possibilities of Personalized 3D Printed Implants—A Case Series Study

Background and Objectives: Following the most recent software and 3D printing developments, the use of personalized 3D printed orthopedic implants for treatment of complicated surgical cases has gained more popularity. Today, orthopedic problems that cannot be solved with standard implants may be effectively addressed using personalized prostheses. The aim of this study is to present the designing, modeling and production stages of four different personalized 3D printed prostheses and their application in clinical cases of patients who underwent treatment in various anatomical locations with a precisely specified indication for implantation. Materials and Methods: Based on computed tomography scanning, personalized 3D printed prostheses were designed, produced and used in four patients within a period of three to five days after injury or admission. Results: Early term follow-ups demonstrated good to excellent results. Conclusions: Personalized 3D printed prostheses offer an opportunity for a treatment of choice and provide good anatomical and functional results, shortened surgical time, less complications, and high satisfaction in patients with appropriate indications. The method should be considered primarily for patients with large bone defects, or such indicated for resection. Personalized 3D printed prostheses have the potential to become more common and beneficial in the future

The effect of rinsing time periods on wettability of elastomeric impression materials: in vitro study

OBJECTIVE: The aim of this study was to determine whether different rinsing time periods affected the wettability of polymerized elastomeric impression materials. MATERIALS AND METHOD: Panasil Contact Plus (PCP), Panasil Contact Non-Surfactant (PCNS), Panasil Initial Contact (PIC), Express (EXP) and Impregum (IMP) impression materials were tested. Standardized samples were rinsed with water for 10 s, 15 s or 20 s, and the wettability was determined by contact angle measurement through an evaluation period of 60 seconds (n=7). Non-rinsed groups were used as control. Measurements were made at 5 time points (at 0, 6, 15, 30 and 60 seconds). Kruskal Wallis test and Conover’s multiple comparison tests were used for all multiple comparisons. Bonferroni adjustment was applied for controlling Type I error (p<0.002). RESULTS: Rinsing 10 s, 15 s or 20 s significantly reduced the wettability of the impression materials PCP, PIC and EXP (p0.002). CONCLUSION: Rinsing the surfactant-containing polyvinylsiloxane impression materials decreased their wettability, whereas no such effect was seen for the surfactant free polyvinylsiloxane and polyether impression materials

Novel water soluble Soya oil polymer from oxidized Soya oil polymer and diethanol amine

A cold water soluble, biobased polymer derived from autoxidized soya oil has been described. Oxidized soya oil polymer was obtained by exposure to air under daylight at room temperature. The thickness of the soya oil at the beginning of the reaction and the oxidation time adversely influenced the molecular weight of the soya oil polymer obtained. The oxidized soya oil polymer obtained was then reacted with diethanol amine to obtain a hydroxylated soya oil polymer. The cold water soluble hydroxylated soya oil polymer was characterized by viscosity measurements, elemental analysis, FT-IR, 1H-NMR, 13C-NMR and cosy-NMR. © 2013 Copyright Taylor and Francis Group, LLC.Bülent Ecevit Üniversitesi: 2011–10—3–02The authors thank Bülent Ecevit University for financial support (Grant# 2011–10—3–02).

Observational case study: bioenergy generation from banana farm residuals in Alanya, Turkey

Fossil fuels have been used as its primary source of energy in the world. This unsustainable energy source is not going to last long. A gradual shift towards green energy should be practiced. In Turkey, even though fossil fuels are used as a primary energy source, renewable energies such as hydro, solar, wind power and biomass have been gaining popularity because of implementation of energy policies and greater understanding on the importance of the green energy usage. Turkey has sustainable agriculture and forestry applications, however, it is still slow and didn't catch up with current trend of sustainability. In the southern part of Turkey, especially in Antalya some of the local agricultural applications are improving. These agricultural practices have possibility to provide a feedstock for energy generation, locally. However, new sources should be sought after to avoid the over dependency on a single source. Hence, other agriculture biomass should be considered such as banana plant biomass which is mainly produced in Alanya, Gazipasa province of Antalya, and Anamur, province of Mersin in Turkey. The banana plant is chosen as the subject of this study due to its availability, high growth rates, carbon neutrality and the fact that it bears fruit only once in a lifetime. This observational case study will explain the potential of banana farm residuals as a new biomass source in Alanya for biogas co-generation in a sustainable way. Banana biomass is feasible as a source of renewable energy in Alanya for local community and also other similar cities in Turkey

Delay estimation based on kinematic track information without time stamps

An algorithm to estimate the delay between two track files without time stamps in a distributed track fusion architecture is proposed. The main aim in delay estimation is to make the proceeding track fusion more accurately. The performance of the proposed algorithm is illustrated on an example in which two radars observe a common surveillance area with one radar sending the track information with a deterministic delay. Moreover, a method is proposed if the delay estimation algorithm presents a bad performance under deterministic delay assumption

A critical review of energy generation from biomass to limit climate change

Industrial and technological development have been brought some environmental problems such as global warming which has a direct correlation with climate change. The main reason for these problems is created by human activities such as fossil fuel demand and agricultural activities which are mainly producing greenhouse gases. One approach is that substituting fossil fuel demand with green energy production such as wind, solar, bioenergy might be sustainable and renewable so it might limit global climate change. At this point, one of the green energy production is converting biomass to bioenergy such as biochar, bio-oil, and biogas. Beside that there are some challenges that might cause food crises and increase hunger because of the agricultural land usage will be switched to energy crops instead of food. However, converting agricultural and food wastes to bioenergy might be more sustainable and reduces crisis risk. Biomass feedstock is feasible to provide a limitation for climate change issue if it is carefully planned and administrated

Substrate critical effect on the structural and H2 Gas sensing characteristics of solution-processed Zn0.075Cu0.025O films

In this study, we report the synthesis of Zn _0.075 Cu _0.025 O films by chemical bath deposition to determine the effect of substrate (glass slide or ZnO seed layer) on the structural and H _2 gas sensing properties of the produced films. The crystal phase, structural topography, surface morphology, and functional groups of the as-synthesized films as well as H _2 gas sensing properties were investigated. Although both films have a hexagonal wurtzite structure, ZnO seed layer-based Zn _0.075 Cu _0.025 O film is more crystalline than glass slide-based Zn _0.075 Cu _0.025 O films. ZnO seed layer-based Zn _0.075 Cu _0.025 O films exhibited much more nanorod and fewer nanosphere forms compared to glass slide-based Zn _0.075 Cu _0.025 O films. EDX analysis and Raman spectra of both samples confirmed the presence of defects in Cu: ZnO samples. ZnO seed layer-based sensors showed higher response (140%) and lower operating temperature (80 °C) compared to glass slide-based sensors (87% response and 140 °C operating temperature). The most important thing to note here is that the fabricated sensors exhibited a high response at room temperature. The responses at room temperature were found as 46% and 23% for the ZnO seed layer-based and glass slide-based sensors, respectively. Sensors operating at room temperature are especially important for commercial applications

Enhanced gas sensing properties of IZO thin films using SILAR

In the last decades, resistive gas sensors based on semiconductor oxides have been the topic of interest for a long time due to their high sensitivity to both oxidizing and reducing gases. These sensors meet the main market requirements such as low cost, small size, and easy maintenance. Currently, much attention has been attracted to finding an effective method to improve the nanomaterials’ sensing ability and selectivity. Sensor devices based on semiconductor oxide like ZnO are important sensing material for detection of hazardous gases [1]. ZnO is the most extensively applied as a gas sensing material, since it has remarkable characteristics necessary for an ideal metal oxide gas sensor such as wide band-gap energy (Eg=3.37 eV) and high binding energy (Ee=60 meV) [2]. Several approaches have been applied to improve gas sensing performance, for instance, morphological changes by doping metal. Especially, indium (In) significantly influences the electrical, chemical, structural, and gas sensing properties of ZnO. In the present work, the effect of In doping on the various properties of ZnO was investigated. The pure ZnO and indium doped ZnO thin films have been synthesized by the SILAR method. The obtained results clearly demonstrated a significant improvement in gas sensitivity by incorporating In into the ZnO
