The Mooring Pattern Study for Q-Flex Type LNG Carriers Scheduled for Berthing at Ege Gaz Aliaga LNG Terminal

Ever growing energy industry requires larger quantities of LNG to be transported by bigger ships between terminals. Every day, new kind of large vessels created by new technologies, and these are used to trade around the globe. This is the dynamic change in shipping industry. But on the other hand these new vessels need to safely berth to existing terminals which we may accept as more static part of the trade. Thus this study born by the request of Ege Gaz Aliaga LNG Terminal management to determine if it is safe to berth to the terminal by a new breed of large LNG carrier type named as Q-Flex and Q-Max. Transas Bridge Simulator NTPRO 5000 series was used in this study for extensive experiments which had been simulated by the use of hook function. During the study, every force applied to mooring hooks and dolphins by the ship lines were divided into 3 dimensions and then measured by simulation experiments. With analysis of the data, required hook and dolphins strengths were determined for the safe mooring arrangements. Upon the completion of the study Ege Gaz Aliaga LNG Terminal became the first safe berth for Q-Flex type vessels in the Mediterranean and the Black Sea. And finally all experiments were confirmed with real life experience when the first Q-Flex type LNG carrier berthed to the Ege Gaz Aliaga LNG Terminal

Synthesis and Characterization of Some Metal Complexes of Isonitroso-2-acetylnaphthalene Derivative

WOS: 000386572500023Nickel(II), copper(II), and zinc(II) complexes with the Schiff base obtained from isonitroso-2-acetylnaphthalene and 1,2-phenylenediamine were synthesized. The compounds were characterized by elemental analyses, FT-IR, UV-Vis, and H-1 and C-13 NMR spectra, conductance measurements, magnetic susceptibility measurements, and thermal analysis. The results suggest tetradentate coordination of the symmetrical Schiff base ligand through the two oxime oxygen atoms and two azomethine nitrogen atoms. The molar conductance data showed that the synthesized complexes are non-electrolytes.Research Foundation of the Nigde University (BAP) [P.N.

Synthesis, spectral, thermal, and magnetic studies of cobalt(II), nickel(II), copper(II), zinc(II), and cadmium(II) complexes with N2O2 donor groups

WOS: 000343828700030A new Schiff base ligand was prepared by condensation of 2-hydroxy-4-methoxybenzaldehyde with 1,2-propanediamine. The ligand and its metal complexes were characterized by elemental analysis, FT-IR, H-1 and C-13 NMR, magnetic moment, molar conductance, UV-Vis, SEM and thermal analysis (TGA). The molar conductance measurements indicated that all the metal complexes were non-electrolytes. IR spectra showed that ligand (L) behaves as a neutral tetradentate ligand and binds to the metal ions by the two azomethine nitrogen atoms and two phenolic oxygen atoms. The electronic absorption spectra and magnetic susceptibility measurements indicated square planar geometry for the Ni(II) and Cu(II) complexes while other metal complexes showed tetrahedral geometry. Also the surface morphology of the complexes was studied by SEM.Research Foundation of the Nigde University (BAP) [P. N.

Evaluación de cuatro formulaciones para el almacenamiento del nematodo entomopatógeno Heterorhabditis bacteriophora en dos estados de actividad

19 p.Para el almacenamiento de nematodos entomopatógenos se requiere formulaciones estables que puedan mantener la viabilidad de los nematodos antes de ser aplicados. Existen formulaciones en vermiculita, esponja, polvo mojable y gránulos dispersables que requieren refrigeración para inducir a una latencia parcial y mantener su viabilidad. En el estudio se evaluó la mortalidad del nematodo entomopatógeno (Heterorhabditis bacteriophora) en cuatro formulaciones utilizando nematodos en estado activo y latente los cual fueron almacenados a 20°C. Se determinó la infectividad de estos nematodos en larvas de Galleria mellonella a 7, 14 y 21 días después de ser almacenados. Los nematodos almacenados a 20°C en estado latente presentaron menor mortalidad en las cuatro formulaciones evaluadas. La formulación en esponja con nematodos en estado latente tuvo la menor mortalidad y no se observó diferencia significativa en estado activo. Las formulaciones en estado de latencia presentaron menor mortalidad lo que significa que inducir a los nemátodos en un estado parcial de latencia redujo el porcentaje de mortalidad para todas las formulaciones. El porcentaje de infectividad fue indirectamente proporcional a la mortalidad en todas las formulaciones solamente a los 21 días después del almacenamiento. El estado de actividad no afectó la infectividad a los 7 y 14 días

Multilevel Turbo Coded-Continuous Phase Frequency Shift Keying (MLTC-CPFSK) over satellite channels in space communication

In this paper, in order to improve bit error performance and bandwidth efficiency, we introduce a new type of Turbo coded modulation scheme, called Multilevel Turbo Coded-Continuous Phase Frequency Shift Keying (MLTC-CPFSK). The basic idea of multilevel coding is to partition a signal set into several levels and to encode separately each level by a proper component of the encoder. In MLTC-CPFSK, to provide phase continuity of the signals, Turbo encoder and Continuous Phase Encoder (CPE) are serially concatenated at the last level, while all other levels consist of only a turbo encoder. Therefore, the proposed system contains more than one turbo encoder/decoder blocks in its structure. The parallel input data sequences are encoded by our multilevel scheme and mapped to CPFSK signals. Then these modulated signals are passed through AWGN and fading channels. At the receiver side, input sequence of first level is estimated from the first turbo decoder. Then the other input sequences are computed using the estimated input bit streams of previous levels. Simulation results are drawn for 4CPFSK two-level turbo codes over AWGN, Rician, and Rayleigh channels for three iterations while frame sizes are chosen as 100 and 1024. Higher error performances are obtained from various type of MLTC-CPFSK systems compared to Trellis Coded CPFSK systems

Optimization of pullulan production from synthetic medium by Aureobsidium pullulans in a stirred tank reactor by response surface methodology

WOS: 000229982200012The production of pullulan from synthetic medium by Aureobasidium pullulans P56 in a stirred tank fermenter was investigated. The kinetics of polysaccharide, pullulan and biomass production was determined. Response surface methodology was used to investigate the effects of three factors (initial sugar concentration, aeration rate and agitation speed) on the concentration of pullulan in batch cultures of A pullulans. In the experiments, the range of values used for the three variables described were; 30-70 g dm(-3) initial sugar concentration, 200-600 rpm agitation speed and 1.0-3.0 vvm aeration rate. No previous work has used statistical analysis in determining the interactions among these variables in pullulan production. Results of the statistical analysis showed that the fit of the model was good in all cases. Aeration rate, agitation speed and sugar concentration had a strong linear effect on pullulan concentration. Moreover, pullulan concentration was significantly influenced by the negative quadratic effects of the given variables and by their positive or negative interactions with the exception that the interaction between agitation speed and aeration rate was insignificant (P > 0.05). Maximum pullulan concentration of 17.2 g dm(-3) was obtained at the optimum levels of process variables (initial sugar concentration 51.4 g dm(-3), aeration rate 2.36 vvm, agitation speed 345.3 rpm). These values were obtained by fitting of the experimental data to the model equation. Scanning electron microscope (SEM) photographs of polysaccharide particles containing different concentrations of pullulan were also taken to observe the morphological differences of the samples.

Listening to Turkish Classical Music Decreases Patients\u27 Anxiety, Pain, Dissatisfaction and the Dose of Sedative and Analgesic Drugs During Colonoscopy: A Prospective Randomized Controlled Trial

AIM: To determine whether listening to music decreases the requirement for dosages of sedative drugs, patients\u27 anxiety, pain and dissatisfaction feelings during colonoscopy and makes the procedure more comfortable and acceptable. METHODS: Patients undergoing elective colonoscopy between October 2005 and February 2006 were randomized into either listening to music (Group 1, n = 30) or not listening to music (Group 2, n = 30). Anxiolytic and analgesic drugs (intravenous midazolam and meperidine) were given according to the patients\u27 demand. Administered medications were monitored. We determined their levels of anxiety using the State-Trait Anxiety Inventory Test form. Patients\u27 satisfaction, pain, and willingness to undergo a repeated procedure were self-assessed using a visual analog scale. RESULTS: The mean dose of sedative and analgesic drugs used in group 1 (midazolam: 2.1 +/- 1.4, meperidine: 18.1 +/- 11.7) was smaller than group 2 (midazolam: 2.4 +/- 1.0, meperidine: 20.6 +/- 11.5), but without a significant difference (P \u3e 0.05). The mean anxiety level in group 1 was lower than group 2 (36.7 +/- 2.2 vs 251.0 +/- 1.9, P \u3c 0.001). The mean satisfaction score was higher in group 1 compared to group 2 (87.8 +/- 3.1 vs 58.1 +/- 3.4, P \u3c 0.001). The mean pain score in group 1 was lower than group 2 (74.1 +/- 4.7 vs 39.0 +/- 3.9, P \u3c 0.001). CONCLUSION: Listening to music during colonoscopy helps reduce the dose of sedative medications, as well as patients\u27 anxiety, pain, dissatisfaction during the procedure. Therefore, we believe that listening to music can play an adjunctive role to sedation in colonoscopy. It is a simple, inexpensive way to improve patients\u27 comfort during the procedure
