Background: In this research, the decomposition of Aroclor 1254, including 20 kinds of poly chlorinated biphenyls (PCBs), in real waste transformer oil in the presence of PEG1000, NaOH, zero valent iron and H2O by microwave (MW) irradiation was studied. Methods: Central composites design (CCD) method was carried out for experimental design. The effects of microwave power levels (200- 1000 W), ...

Bu çalışmanın amacı; Gemlik zeytin çeşidinde sulama ile çiçeklenme öncesi ve sonrası dönemlerde yapraktan yapılan farklı gübre uygulamalarının meyve ağırlığı, eni, boyu, indeksi (boy/en), et çekirdek ağırlıkları, oranı üzerine etkilerini incelemektir. Çalışmada mineral (KNO3+H3BO3+ZnSO4 Üre+MgSO4) organomineral gübreler (Raykat Growth, Raykat Start Fitomare) kullanılmış, Kontrol ağaçlara su püs...

Molten salt LiNO3-NaNO3-KNO3 has been investigated as heat transfer and thermal storage media for its low melting point good performance. In this paper, nanofluids were synthesized by dispersing MgO nanoparticles into LiNO3-NaNO3-KNO3, the effects of on properties studied with different sizes (20–100 nm) mass percent concentrations (0.5–2.0 wt.%). The addition had little effect temperature, led...

This study aims to investigate ion composition of PM2.5 in various sites and seasons identify the main sources on spatial temporal basis. compositions two urban rural areas Northern Thailand 2019 were investigated distinguish traffic open burning sources. During season, average concentrations (104 ± 45 ?g m?3) slightly higher than those (94 39 m?3). Source identification by cluster analysis dur...

The structural and energetic characteristics of O3–H2O complexes have been investigated by means of B3LYP, MP2, MP4(SDTQ), CCSD(T) and QCISD(T) methods in conjunction with the AUG-cc-pVDZ and AUG-cc-pVTZ basis sets. Six conformers were found for the O3–H2O complex. Two different intermolecular interactions were expected to participate in the formation of complexes, namely conventional O∙∙∙H hyd...
