BOYACIOĞLU, SEDA ÖRENAY; KORKMAZ, MEHMET; Kahraman, Erkan; Yildirim, Hatice; Bora, Selin; Ataman, Osman Yavuz (2017-01-01)
The mechanism of boron effect on human transcription and translation has not been fully understood. In the current study it was aimed to reveal the role of boron on the expression of certain transcription factors that play key roles in many cellular pathways on human subjects chronically exposed to low amounts of boron. The boron concentrations in drinking water samples were 1.57 +/- 0.06 mg/l for boron group while the corresponding value for the control group was 0.016 +/- 0.002 mg/l. RNA isolation was per...
Investigation of neutron sensitivity of un-doped and Dy-doped CaB4O7 for thermoluminescence applications
Iflazoglu, Sera; Yılmaz, Ayşen; KAFADAR, VURAL EMİR; YAZICI, AHMET NECMEDDİN (2018-09-01)
In this study, thermoluminescence characteristics of un-doped and Dy-doped calcium tetraborate (CaB4O7) compounds are reported. The polycrystalline powder samples of un-doped and Dy-doped CaB4O7 were prepared by a solid-state reaction at high-temperature method. The identification and characteristics of the obtained compounds were determined by X-ray diffraction, Fourier transform infrared analysis, differential thermal analysis, thermogravimetric analysis, and scanning electron microscopy. The glow curves ...
Antioxidant responses of tolerant and sensitive barley cultivars to boron toxicity
Karabal, E; Yucel, M; Öktem, Hüseyin Avni (2003-06-01)
Effect of boron toxicity on antioxidant response of sensitive (Hamidiye) and tolerant (Anadolu) barley (Holgarium vulgar) cultivars was investigated. Eight days old hydroponically grown seedlings were subjected to 5 and 10 mM boric acid treatments for 5 days. Growth parameters (dry-wet weight), protein, proline, MDA, H2O2 contents, membrane damage and activities of superoxide dismutase (SOD). ascorbate peroxidase (APX), catalase (CAT) and glutathion reductase (GR) was evaluated in root and shoot tissues. Co...
Boron determination in body fluids by inductively coupled plasma optical emission spectrometry and inductively coupled plasma mass spectrometry
Bora, Selin; Ataman, Osman Yavuz; Department of Chemistry (2010)
Boron element plays an important role for our country since approximately 70% of the world’s reserves are in Turkey. It is widely used in different areas of industry. Besides being vital for the plants, it is important also for human health. It has been shown that high boron exposure does not affect fertility negatively and also with an increasing boron exposure, risk of prostate and cervical cancers decreases. There are different opinions regarding health effects of boron. There are both positive and negat...
Optimization of fabrication steps for n-type c-Si solar cells
Orhan, Efe; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2019)
Crystalline silicon (c-Si) solar cells fabricated on p-type wafers are still dominating the photovoltaic (PV) industry due to advantages in device processing and early focus on p-type cells in the development phase of the industry. Over the years, studies on n-type Czochralski (CZ) substrates have shown that they can be more desirable for the terrestrial applications due to superior material and process advantages such as higher minority carrier lifetime, easier passivation of the surface, absence of light ...
