The Evaluation According to Integrated Disaster Management of the Newspaper Headlines After the Düzce Earthquake

Doğa kaynaklı afetler toplumların fiziksel, psikolojik, sosyo-ekonomik durumları üzerinde ciddi etkiler meydana getirmektedir. Ülkemiz de jeolojik konumu itibariyle depremler başta olmak üzere pek çok afete maruz kalmaktadır. Depremlerin yıkıcı etkilerinin azaltılması etkili ve bütünleşik bir afet yönetimi ile mümkün olabilmektedir. 1999 Marmara depremi sonrasında, risk azaltma evresinde yapılması gereken, planlama, zarar azaltma ve hazırlık konularında eksiklikler tespit edilmiştir. Kriz yönetimi anlayışıyla yönetilmeye çalışılan depremde pek çok koordinasyon ve iletişim sorunları yaşanmıştır. Bütünleşik afet yönetimi sistemi ile afet öncesi zarar azaltma ve hazırlık çalışmalarına ağırlık vermek elzemdir. Afetler öncesi halkın bilgilendirilmesi ve afetlere hazırlık konusunda bilinçlendirilmesi meydana gelen acil durumların afete dönüşmesini önlemeye yardımcı olacaktır. Medyanın da bilgilendirme ve bilinçlendirme konusunda önemi yadsınamaz. Medya yalnızca afetlerden sonra bilgilendirme olarak değil, afet öncesi bireylerin yapması gerekenleri de kapsayan bilinçlendirme çalışmalarına yer vermelidir. Bu çalışmanın amacı da 23 yıl sonra meydana gelen Düzce depreminin gazete manşetlerinde afet yönetimi süreçlerine göre nasıl ele alındığını ve süreçteki değişimi değerlendirmektir. Çalışmada 30 gazete ve bu gazetelerdeki 210 manşet değerlendirilmiş olup, 98 (%46,6) manşet Düzce depremi ile ilgili olduğu görülmüştür. Afet yönetimi süreçlerine göre 46 (%46,9) manşet risk azaltma evresine yönelik, 35 (%35,7) manşet de kriz yönetimi evresine yönelik olarak bulunmuştur.Natural disasters have critical effects on the physical, psychological and socio-economic conditions of societies. Due to its geological location, our country is exposed to many disasters, especially earthquakes. Reducing the destructive effects of earthquakes is possible with an effective and integrated disaster management. After the 1999 Marmara earthquake, deficiencies in planning, mitigation and preparation were identified, which should be done in the risk reduction phase. Many coordination and communication problems were experienced in the earthquake, which was tried to be managed with the understanding of crisis management. It is essential to focus on pre-disaster mitigation and preparedness studies with an integrated disaster management system. Informing the public before disasters and raising awareness about disaster preparedness will help prevent emergencies from turning into disasters. The importance of the media in informing and raising awareness is undeniable. The media should include awareness raising activities, which include not only information after disasters, but also what individuals should do before disasters. The aim of this study is to evaluate how the Düzce earthquake, which occurred 23 years later, was handled in newspaper headlines according to disaster management processes and the change in the process. In the study, 30 newspapers and 210 headlines in these newspapers were evaluated, and 98 (46.6%) headlines were related to the Düzce earthquake. According to disaster management processes, 46 (46.9%) headlines were found for the risk reduction phase, and 35 (35.7%) headlines were for the crisis management phase

Development of a liquid-liquid extraction method of resveratrol from cell culture media using solubility parameters

YesThe extraction of bioactive compounds, produced by plant cell cultures, directly from their culture medium, which contains other by-products, is a great challenge. Resveratrol extraction from its grapevine cell cultures is considered here as an example to improve the extraction processes from plant cell cultures using solubility parameters. Successive liquid-liquid extraction (LLE) processes were exploited to extract resveratrol from the culture medium with an extraction ratio approaching 100%, high selectivity and minimum amounts of solvents. The calculations of partition coefficients as a function of solubility parameters demonstrated that benzyl benzoate is the most suitable intermediate solvent to extract resveratrol from its aqueous medium. The calculations also illustrated the high ability of methanol and ethanol to extract resveratrol from benzyl benzoate. The physicochemical properties of benzyl benzoate and processing conditions were exploited to separate it from aqueous media and organic solvents. The agitation method, component ratios and extraction time were studied to maximize the extraction yield. Under the best studied conditions, the recovery of resveratrol from different culture media approached ∼100% with a selectivity of ∼92%. Ultimately, the improved extraction processes of resveratrol are markedly efficient, selective, rapid and economical.Mohammad Amin Mohammad gratefully acknowledges CARA (The Council for At-Risk Academics, Stephen Wordsworth and Ryan Mundy) for providing the financial support for an academic fellowship

Synthesis, Thermal Kinetic Analysis and DFT Calculations of Pyrazine and Pyridine Complexes of Copper(II) Thiocyanate

Two NNN type ligands namely bis-2,6-(pyrazol-1-yl) pyridyne (pp) and bis-2,6-(3,5-dimethyl-pyrazol-1-yl) pyridyne (dmpp) were prepared by the use of 2,6-dichloropyridine, pyrazol and 3,5-dimethylpyrazol. Using these ligands with SCN co-ligand two mononuclear Cu(II) complexes were synthesized and characterized. The complexes were investigated by thermogravimetry (TG) and differential thermal analysis (DTA) and subjected to isothermal and nonisothermal kinetic analyses. TG and DTA results indicated that the complexes showed two distinctive degradation steps and the NNN type ligand was removed from the structure at temperatures above 300 °C. The activation energies of these complexes and same thermodynamic parameters of these thermal reactions have been calculated. The situation of d orbitals of Cu(II) ion, the electron densities of donor atoms of the ligands, natural bond orbital (NBO) analysis, the theoretical IR spectra and HOMO-LUMO energy levels computed by the use of DFT/B3LYP methods with 6-311G (d) basis set in Gaussian 09 software. These data were employed to enlighten the thermal degradation of the complexes prepared

Synthesis, crystal structure, chromatographic seperation, and thermogravimetric investigation of a ONNO type asymmetric Schiff base and its trinuclear complexes

Inal, Emine Kubra/0000-0001-8334-2791;WOS: 0003404554000071,3-Propanediamine was put to react with 2-hydroxybenzaldehyde and 2-hydroxyacetophenone sequentially in aprotic medium. The crystalline product was examined by high performance liquid chromatography. The composition was 66% asymmetric Schiff base N(2-hydroxybenzylidene)-N'(2-hydroxyacetophenone)-1,3-propanediamine (SALLACH(2)) and 33% bis-N,N'(2-hydroxyacetophenylidene)-1,3-propanediamine (LACH2). As the crystals were uniform and of appropriate size, the molecular model of the material was revealed by X-ray diffraction. It was seen that two molecules of SALLACH(2) and one molecule of LACH(2) formed the mixed crystals. The substance was separated to its components and the asymmetric Schiff base was purified with a silica column. The substance was characterized with elemental analysis, FT-IR, MS, (HNMR)-H-1, and C-13 NMR. In addition, six tri-nuclear complex with the nuclear structure of Ni-II-Ni-II-Ni-II, Ni-II-Cu-II-Ni-II, Ni-II-Mn-II-Ni-II were prepared from this Schiff base and stoichiometry was determined by elemental analysis, FT-IR and thermogravimetry. Finally, the molecular structures of two complexes were brought to light by XRD which highlights the asymmetry of the ligand more clearly.University of Ankara Scientific Research FundAnkara University [12B4240003]; Ahi Evran University Scientific Research FundAhi Evran University [4001.12.014]Financial support of this work by the University of Ankara Scientific Research Fund (contract no. 12B4240003) and Ahi Evran University Scientific Research Fund (contract no. 4001.12.014) are gratefully acknowledged.
