Phase-plane analysis for a simplified model of Purkinje cell dendrite

Özer, Mahmut

In this study, phase-plane analysis is carried out for a simplified model of Purkinje cell dendrite in terms of voltage-gated ionic channels involved. State variables, nullclines and equilibrium points of the model are determined, and effects of ionic channel conductance and injected current on the shape of nullclines and the equilibrium points are investigated.

A molecular mechanics and semiempirical molecular orbital study on the conformation of polynorbornene chains

Yilmaz-Savaşkan, Sevil | Abbasoğlu, Rza | Hazer, Baki

The conformational analysis of polynorbornene (PNB) chains was investigated with the AM1, MM2, AMBER and OPLS methods taking into consideration the possibility of binding of norbornene monomers to each other at various positions, i.e. exo-exo, exo-endo, endo-endo. The chain that is formed by connecting exo-endo positions of the monomers has lower torsional barrier energy than those formed with bonds at other positions and has more flexibility. It is determined that the thredisyndiotactic chain formed by exo-endo addition adopts a helix structure and has a coil shape. The disyndiotactic chain f ...Daha fazlası

Progression in acute ischemic stroke: frequency, risk factors and prognosis

Sumer, M | Ozdemir, I | Erturk, O

Background and purpose: The aim of this study was to investigate the frequency, possible predictive factors and the prognosis of deteriorating ischemic stroke. Methods: A total of 266 stroke patients who presented within 24 h of onset were enrolled. Clinical deterioration was defined as a decrease of 1 points in the Canadian Neurological Scale (CNS). Rankin Score (RS) was performed at discharge and at six months. Results: Of the 266 patients studied, 26 (9.8%) worsened. Involvement of posterior circulation (odds ratio (OR) 3.16) and noncardioembolic infarction (OR 4.5) were found to be indepen ...Daha fazlası

Zinc, copper and iron concentrations in cerebral cortex of male rats exposed to formaldehyde inhalation

Özen O.A. | Songur A. | Sarsilmaz M. | Yaman M. | Kuş I.

Retrospective cohort studies and clinical findings have suggested effects of formaldehyde exposure on the central nervous system in anatomists, embalmers and pathologists. On the other hand, harmful effects of formaldehyde inhalation on the nervous system are not well documented. The concentrations of elements such as zinc, copper and iron within the cerebral cortex indicate whether physiological conditions are maintained. In this study, adult male albino Wistar rats were exposed to formaldehyde at different concentrations (0; 6.1; 12.2 mg·m-3) and during different periods of time (subacute-su ...Daha fazlası

Production of bacterial polyesters from some various new substrates by Alcaligenes eutrophus and Pseudomonas oleovorans

Koçer, Halil | Borcaklı, Mehlika | Demirel, Songün | Hazer, Baki

Poly(3-hydroxy alkanoate)s (PHA)s are bacterial polyesters that have, due to their biodegradability and biocompatibility, attracted considerable industrial interest. All the substrates used in feeding Alcaligenes eutrophus and Pseudomonas oleovorans have been reviewed as far as we know, and some more new substrates or mixtures have been used in PHA production by microorganisms. Alcaligenes eutrophus was fed with 4-pentenoic acid, 2-hydroxy ethyl methacrylate (HEMA), corn oil acids, linseed oil acids and limonene as well as mixtures of acetic acid and glucose or lactose. Either HEMA as a sole c ...Daha fazlası

Denizden çıkarılan kumun beton mukavemetine etkisi (2003)

Özkan, Ömer

1999 yılında meydana gelen depremler sonrasında, kıyı şeridinde bulunan şehirlerde yapı malzemesi olarak kullanılan betonun karışımında deniz kumunun kullanılmasının beton mukavemetine ve dayanımına etkisi tartışılmaya başlanmıştır. Bu çalışmada Zonguldak-Alaplı bölgesinde denizden çıkarılan kum ile Zonguldak-Alaplı Çay'ından çıkarılan kumun mukavemetlerinin zamana göre değişimleri karşılaştırılmıştır. Kullanılan ince agregada birim ağırlık, özgül ağırlık, ince madde oranı, organik madde oranı tayin edilerek, incelik modülü deneyleri yapılmıştır. Yapılan deneyler neticesinde denizden çıkarılan ...Daha fazlası

Sulfur dioxide adsorption isotherms and breakthrough analysis on molecular sieve 5A zeolite

Kopaç, Türkan | Kocabaş, Sefa

In this study sulfur dioxide adsorption and rate were investigated on molecular sieve 5A zeolite in a packed bed system at 473 K. The experimental adsorption isotherms were compared with Langmuir, Freundlich, and Dubinin-Radushkevitch-Kaganer (DRK) adsorption isotherm models. The simple Langmuir and the Freundlich models provided a better description of sulfur dioxide sorption on molecular sieve 5A zeolite, so that a selective surface adsorption mechanism for adsorption of sulfur dioxide on molecular sieve 5A zeolite can he suggested. The breakthrough behavior for sulfur dioxide adsorption on ...Daha fazlası

Prediction of sulfur dioxide daily levels in the City of Zonguldak using an adaptive neuro-fuzzy based method

Yıldırım, Yılmaz | Bayramoğlu, Mahmut | Hasıloğlu, Samet

Air pollution continues to be a major problem in many countries. Mathematical models are useful in relating emissions to air quality under a variety of meteorological conditions and source emission concentrations over an urban area. Meanwhile, the forecasting capability of sophisticated models is limited to very large and complex terrains. In this study, an adaptive neuro-fuzzy logic method has been developed to estimate the impact of meteorological factors on SO2 pollution levels. The model satisfactorily forecasts the trends of SO2 concentration levels with a performance between 78-90%.

Development of a Regression Model to Forecast Ozone Concentration in Istanbul City, Turkey

Tecer L.H. | Ertürk F. | Cerit O.

In this study, an air quality model including pollutants (NOx, non methane hydrocyarbons (NMHC)) and meteorological parameters (wind speed, solar radiation, rain, relative humidity and temperature) has been developed for the formation of ozone in Istanbul City. This model has been used to predict the daily ozone concentrations at different time periods and to examine various control strategies. The ozone prediction model sufficiently explained the change of diurnal and seasonal ozone formation. The diurnal pattern of ozone increases from 12 at noon to 4 a.m. Moreover, the seasonal change of oz ...Daha fazlası
