An Efficient Algorithm To Determine The Periodic Steady-State Solutions Of Nonlinear Systems Using Extended Spectral Analysis, Gülay Tohumoğlu
An Efficient Algorithm To Determine The Periodic Steady-State Solutions Of Nonlinear Systems Using Extended Spectral Analysis, Gülay Tohumoğlu
Turkish Journal of Electrical Engineering and Computer Sciences
A new method for the solution of nonlinear periodic systems was developed. It avoids the time domain calculations of the whole network equations. In the proposed method, by forming the augmented network as linear and nonlinear subnetworks these subnetworks are formulated in complex frequency and time domain respectively. Using spectral analysis the steady-state periodic solution of the whole nonlinear network is reached by an iterative approach. The method can be applied efficiently to weak and strong nonlinear circuits equally well. When we divide the network into a large linear subnetwork and a small nonlinear subnetwork, this method can be applied …

Multipliers Between Orlicz Sequence Spaces, P. B. Djakov, M. S. Ramanuan
Multipliers Between Orlicz Sequence Spaces, P. B. Djakov, M. S. Ramanuan
Turkish Journal of Mathematics
Let $M, N $ be Orlicz functions, and let $D(\ell_M , \ell_N ) $ be the space of all diagonal operators (that is multipliers) acting between the Orlicz sequence spaces $\ell_M$ and $\ell_N$. We prove that the space of multipliers $D(\ell_M , \ell_N )$ coincides with (and is isomorphic to) the Orlicz sequence space $ \ell_{M_N^{*}} ,$ where $ M_N^{*} $ is the Orlicz function defined by $M_N^{*}(\lambda ) = \sup \{ N(\lambda x) - M(x), \; x \in (0,1) \}$.

Studies On The Methylation Of 5-Nitro-Benzimidazoles, Mashooda Hasan, Farzana Shaheen, Uzma Yunus
Studies On The Methylation Of 5-Nitro-Benzimidazoles, Mashooda Hasan, Farzana Shaheen, Uzma Yunus
Turkish Journal of Chemistry
Methylation of 2H, 5-nitro- (1) and 2-ethyl, 5-nitro- (2) benzimidazoles separately with methyl iodide in acetone in the presence of potassium carbonate yielded 2H, 5/6-nitro-(3A and 3B) and 2-ethyl, 5/6-nitro- (4A and 4B) methylbenzimidazoles respectively. Methylation of 1 and 2 in dimethylformamide in place of acetone yielded not only 3A, 3B and 4A, 4B respectively, but in addition 1,3-dimethyl-5-nitro-benzimidazol-2-one (5) was also obtained in each case. The structure of the synthesized compounds was determined with the help of mass and ^1H NMR spectroscopic analysis.

Lymphocyte Subsets In Acute Post-Streptococcal Glomerulonephritis, Yavuz Tekeli̇oğlu, Hi̇lal Mocan, M. Zi̇ya Mocan, H. Önder Ersöz
Turkish Journal of Medical Sciences
This prospective study was designed to investigate lymphocyte subsets in acute post-streptococcal glomerulonephritis (APSGN). Peripheral blood lymphocytes were analyzed using fluorescein isothiocyanate (FITC) labeled CD3, CD4, CD8, CD14, CD19, CD45, CD56, CD45RA and CDW29 monoclonal antibodies by flow cytometry. Twenty patients aged 14-22 years who fulfilled the diagnostic criteria for APSGN were evaluated during the 1st and 12th weeks of the of disease. Twenty-four age-matched healthy subjects served as controls. At the onset of the disease, all patients had macroscopic haematuria with red blood cell casts in urine, proteinuria (1.06±0.21 g/d), low complement 3 (C3) levels (200 IU/ml), edema, oliguria …

Turkish Journal of Medical Sciences
Rationale: In this study the efficacy of Lamotrigine was evaluated in children with medically intractable epilepsy. Methods: 22 epileptic children, ranging between 4.2 years and 15 years of age (mean 9.3 years) were included in this study. Twelve (54.5%) were male and 10 (45.5%) were female. The seizure types were classified according to the International League Against Epilepsy criteria: simple partial seizures (8 cases), infantile spasms (4 cases), generalized tonic-clonic seizures (2 cases), tonic seizures (2 cases), complex partial seizure (2 cases), typical absence seizures (2 cases), myoclonic astatic seizures (1 case) and atypical absence seizures (1 case). The neurological …

Invasiveness Of Radiological Procedures: State-Trait Anxiety In Women Undergoing 3 Different Investigations And 3 Months Follow-Up, Fatma Gül Aksoy, Ayşegül Özdemi̇r, Yasemi̇n Genç
Turkish Journal of Medical Sciences
Over the past decade, there has been considerable growth in interest in the application of stress management techniques for the preparation of patients needing to undergo noxious medical procedures. Here, we studied state-trait anxiety in women awaiting three different radiological examinations; abdominal ultrasonography, mammography, and hysterosalpingography, which involved various degrees of intrusiveness, and low, intermediate, and high levels of pain and physical/emotional discomfort respectively. We aimed to investigate whether the degree of anxiety corresponded to the level of invasiveness. In addition, we examined the impact of demographic variables on the degree of anxiety and conducted three months of follow-up measurements. …

Sensory Evaluation And Determination Of Some Physical And Chemical Characteristics Of Shrimp During Gold Storage, Candan Varlik, Taçnur Baygar, Özkan Özden, Nuray Erkan, Sühendan Mol
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to determine the quality changes in shrimp stored at 4°C. In the study, whole shrimp samples were placed into straphore plates and stored in a refrigerator (+4°C). Each plate contained 250g samples. Every day the samples were analyzed for sensory properties, Total Volatile Basic Nitrogen (TVB-N) content, Trimethylamine Nitrogene (TMA-N) content, pH value and moisture content. According to findings of sensory, physical and chemical analyses the samples were found to be of "good quality" at day 0, "good quality," at day 1 and "spoiled" after 2 days.

Mass-Radius Relations For Helium White Dwarfs, Ri̇kkat Ci̇velek, Ni̇lgün Kiziloğlu
Turkish Journal of Physics
We studied the static mass-radius relation of white dwarf stars with masses greater than 0.45 $M_\odot$. We assumed pure degenerate helium interiors at a finite temperature with luminosity-mass ratio due to neutrino energy loss. We compared the obtained M-R relation with those of other writers.
An Extended Adiabatic Approach For Nuclear Reactions, Mustafa Yilmaz, Bülent Gönül
An Extended Adiabatic Approach For Nuclear Reactions, Mustafa Yilmaz, Bülent Gönül
Turkish Journal of Physics
In this letter, an alternative approximation is developed for the treatment of breakup process in nuclear reactions, which presents a way of evaluating non-adiabatic corrections to the adiabatic model three-body wavefunction by introducing a more consistent prescription for the continuum n-p center of mass energy. Although the present formalism goes beyond the quasi-adiabatic approach, due to the use of exact continuum channel energies, its application to deuteron involving reactions at medium energies shows that such an approach can not be used in its present form. A possible reason behind this failure is discussed.

Temperature dependence of Vickers microhardness of ln$_x$ Bi$_{2-x}$ Te$_3$ single crystals with x ranging from 0.1 to 0.5 has been studied. Loading time dependence of microhardness at different temperatures has been used for creep study in the temperature range 300 K to 400 K. The activation energy for indentation creep of the crystals has been evaluated.
