Bu çalışmada, saf nikel oksit (NiO) ve Evropiyum (Eu) katkılı NiO nanoparçacıklar sol-jel yöntemi kullanılarak sentezlendi. Ni kaynağı olarak Nikel (II) asetat tetrahidrat Eu ise klorür kullanıldı. Sentezleme işlemi 80 ℃’de 3 saat sürede gerçekleştirildi. Sentezlenen 450 1 süreyle tavlandı. Nanoparçacıkları oluşturan bileşikler X-ışını kırınımı (XRD) analiz edildi. Nanoparçacıkların morfolojile...

For sensing systems that characterize the spectro-polarimetric radiance reaching the camera, the origin of the sensed phenomenology is a complex mixture of sources. While some of these sources do not contribute to the polarimetric signature, many do such as the downwelled sky polarization, the target and background pBRDF(polarimetric bi-directional reflectance distribution function), the upwell...

We examine the ability of the Expansionary Fiscal Contraction (EFC) hypothesis to explain the performance of of OECD economies during times of crisis. We ̄nd some limited evidence in its favour: if public consumption is reduced in response to a ̄scal crisis (as de ̄ned by a high level of debt), private consumption does seem to increase. However the size of the e®ect is smaller than that typicall...

Bu çalışmada, alizarin red S’in silika jel üzerine çözeltiden adsorpsiyonu araştırılmıştır. pH, adsorbent konsantrasyonu ve temas süresi gibi etkenlerin S boyar maddesinin adsorpsiyon davranışı üzerindeki etkisi incelenmiştir. 25 0C sıcaklıkta, 20 mg adsorban mg/L adsorbat çözeltilerle kinetiği, yalancı birinci mertebeden ikinci modelleri olmak üzere iki kinetik model kullanılarak Adsorpsiyonun...

The destructive soilborne Fusarium species is one of the most serious challenges facing agriculture. Mycotoxins produced by spp. can induce both acute and chronic toxic effects on humans animals. Massive investments have been made in last few decades to develop an appropriate management strategy control cereals, particularly wheat, using genetic resistance other practices, with varied outcomes....

AIMS To investigate the effect of tissue preparation on immunostaining and to establish whether there is a standard tissue preparation schedule that allows optimal demonstration of all antigens. METHODS Blocks of tonsil were subjected to variations to a standard fixation, processing, and section preparation schedule. The sections were stained with five antibodies-L26 (CD20), UCHL1 (CD45RO), C...
