Article Tc-99m Erythromycin Lactobionate Inhalation Scintigraphy in Parenchymal Lung Diseases(Elsevier Science inc, 1999) Durak, H; Aktogu, S; Degirmenci, B; Sayit, E; Ertay, T; Dereli, SWe have investigated Technetium 99m erythromycin lactobionate (Tc 99m EL) clearance from the lungs after inhalation, in the presence of an alveolitis. Eighteen patients (6 sarcoidosis, 7 idiopathic fibrosis, and 5 miliary tuberculosis) were imaged after the patients inhaled 1,110 MBq of Tc 99m EL. Clearance half time for the first 45 min, for 24 h, and retention at 24 h correlated with percentage of lymphocytes in bronchoalveolar lavage fluid (BAL) (r =.729, r =.883, and r =.826, respectively). There was a positive correlation between peripheral penetration (PP) and forced expiratory volume in 1 s (FEV1) (r =.806) and forced vital capacity (FVC) (r =.781). Retention was more marked in sarcoidosis compared with tuberculosis (0.025 < p less than or equal to 0.05). Radioaerosol lung imaging may reflect the pulmonary function impairment in parenchymal lung diseases. Retention of Tc 99m EL may be related to number of BAL cells or presence of a lymphocytic alveolitis. Long residency time of Tc 99m EL in the lungs implies that erythromycin can also be administered by inhalation for therapeutic purposes. NUCL MED BIOL 26;6:695-698, 1999.

Due to space limitation the barrel calorimeters do not contain completely the hadronic shower and an outer calorimeter (HO) was designed, constructed and inserted in the muon system of CMS to measure the energy leakage. Testing and calibration of the HO was carried out in a 300 GeV/c test beam that improved the linearity and resolution. HO will provide a net improvement in missing E T measurements at LHC energies. Information from HO will also be used for the muon trigger in CMS. © 2008 Springer-Verlag / Società Italiana di Fisica.Article Citation - WoS: 32Citation - Scopus: 34The Cms Barrel Calorimeter Response To Particle Beams From 2 To 350 Gev/C(Springer Verlag, 2009) CMS HCAL/ECAL Collaborations; Sönmez, NasufThe response of the CMS barrel calorimeter (electromagnetic plus hadronic) to hadrons, electrons and muons over a wide momentum range from 2 to 350 GeV/c has been measured. To our knowledge, this is the widest range of momenta in which any calorimeter system has been studied. These tests, carried out at the H2 beam-line at CERN, provide a wealth of information, especially at low energies. The analysis of the differences in calorimeter response to charged pions, kaons, protons and antiprotons and a detailed discussion of the underlying phenomena are presented. We also show techniques that apply corrections to the signals from the considerably different electromagnetic (EB) and hadronic (HB) barrel calorimeters in reconstructing the energies of hadrons. Above 5 GeV/c, these corrections improve the energy resolution of the combined system where the stochastic term equals 84.7 ± 1.6% and the constant term is 7.4 ± 0.8%. The corrected mean response remains constant within 1.3% rms. © Springer-Verlag / Società Italiana di Fisica 2009.Correction Citation - WoS: 4Citation - Scopus: 2Erratum: the Cms Barrel Calorimeter Response To Particle Beams From 2 To 350 Gev/C (the European Physical Journal C (2009) 60 (359-373) Doi: 10.1140/Epjc(Springer Verlag, 2009) Karapınar, Güler[No abstract available]Conference Object Citation - WoS: 7Modeling of Low Temperature Geothermal District Heating Systems(Taylor and Francis Ltd., 2004) Yıldırım, Nurdan; Gökçen, GüldenIn this work, low temperature geothermal district heating systems with heat pumps have been studied and compared with fuel-oil boiler heating systems for intermittent and continuous regimes according to the optimum indoor air temperature and operational cost. Izmir Institute of Technology (IZTECH) Campus is taken as a case study. Various heat pump and boiler configurations are studied to meet required duty. Operational cost analysis for each alternative is conducted. According to the results, for IZTECH Campus the best alternative, which gives the optimum indoor air temperature and the lowest operational cost, is heat pump continuous regime.Conference Object Antioxidant, Antimicrobial and Cytotoxic Activities of Some Turkish Plant Extracts(John Wiley and Sons Inc., 2006) Altıok, Evren; Asbagh, L. Abbasi; Bulut, Çisem; Ülkü, Semra; Bayraktar, OğuzPlant extracts have been known to possess notable biological activity, including antioxidant, antimicrobial and cytotoxic properties. There is a growing interest in the use of natural products in the human food industries as consumer resistance to synthetic additives increases. These products can be used to improve human health. In vitro antioxidant, antimicrobial and cytotoxic activities of ethanol extracts of some plants from Urla region in Turkey were investigated. Plant materials were collected from Pistacia lentiscus, Vitex agnus-castus, Cistus creticus and Nerium oleander in October, November and December.Conference Object Citation - WoS: 1Kinetic and Thermodynamic Properties of Crude and Three-Phase Partitioned Polygalacturonase From Aspergillus Sojae(Elsevier, 2007) Doğan, Nergiz; Tari, Canan; Göğüş, NihanCommercial preparations of pectinolytic enzymes derived from fungi are well known to have high biotechnological value in the industry. Since potential applications of pectinases in vari- ous fields of food, paper, textile and waste water treatment are increasing, it is important to understand the properties of these enzymes for efficient and effective usage.Conference Object Effect of Symbiotic Relationship of Lactobacillus Butgaricus 77 and Streptococcus Thermophilus 9512 on Betagalactosidase and Lactic Acid Production(Elsevier, 2007) Üstok, Fatma Işık; Tari, Canan; Harsa, ŞebnemEnzyme production which is a growing field of biotechnology has an annual world sale close to billion dollars. Therefore isolation of new strains producing novel enzymes is important for industrial enzyme production.Conference Object The Cytoprotective Effects of Zinc on Cyclophosphamide Induced Hematoxicity(Elsevier Ltd., 2007) Ayhancı, Adnan; Doğan, Sevgi Zeynep; Appak, Sıla; Doğan, Sevgi[No abstract available]Article Citation - WoS: 14Particle Deposition Simulation Using the Cfd Code Fluent(Maney Publishing, 2000) Yılmaz, Selahattin; Cliffe, K. R.Particles of Soda Lime Silica Glass were used to simulate fly ash in the modelling of particle deposition from a high-temperature flue gas on to a superheater tube. The computational fluid dynamic code FLUENT was used and experimental deposition data were obtained from a rig comprising a small scale furnace containing an air-cooled probe. The effects of particle size, gas velocity and temperature on deposition were investigated. The effects of inertia, eddy impaction, thermophoresis and gravity on the particle trajectories were considered. The number of particles captured by the probe and the furnace surfaces were predicted and agreement with experimental results was found to be a function of particle size with the best agreement achieved for 16- and 26-mu m particles. Deposition was controlled by the kinetic energy of the particles and the adhesive forces of the surface. It is postulated that, for small particles, there was insufficient energy to bond them to the surface whereas for larger particles their kinetic energy was too targe. Thermophoresis did not play a significant part in the deposition process because, although the temperature gradient was large, 400 degrees C mm(-1) in the thermal boundary layer, the small particles (6 and 8 mu m) were unable to reach the thermal boundary layer (9 mm) which was much smaller than the hydrodynamic boundary layer (49.5 mm).
