The spectroscopic (FT-IR, FT-Raman, UV and NMR) first order hyperpolarizability and HOMO-LUMO analysis of dansyl chloride
(Elsevier, 2014)The solid phase FT-IR and FT-Raman spectra of dansyl chloride (DC) have been recorded in the regions 400-4000 and 50-4000 cm-1, respectively. The spectra have been interpreted in terms of fundamentals modes, combination ... -
Reference-plane invariant transmission-reflection method for measurement of constitutive parameters of liquid materials
(2013)We propose a new transmission-reflection method for measuring constitutive parameters of liquid samples inside an asymmetric measurement cell (a sample over a low-loss holder in vertical position inside an empty waveguide ... -
Damages on reinforced concrete buildings due to consecutive earthquakes in Van
(2013)Consecutive earthquakes occurred on October 23rd, 2011 in Ercis and on November 9th, 2011 in Edremit that are townships located 90. km and 18. km far from Van city in Turkey, respectively. A total of 28,000 buildings were ... -
Comparison of the effects of different types of tube inserts on two-phase flow instabilities
(2013)Turbulence promoting inner elements such as rings, wings or winglets, twisted tapes, etc., is widely used in single- and two-phase flows. In this experimental work, the two-phase flow instabilities of forced convection ... -
Fuzzy weighted association rule based solution approaches to facility layout problem in cellular manufacturing system
(2013)This study aims to propose new solution approaches based on fuzzy weighted association rules for facility layout problem in a cellular manufacturing system. The facility layout problem under concern has two important ... -
Analysis of amplitude and slope diffraction coefficients
(2013)The diffraction mechanism is used for field prediction in both light and shadowed regions. Slope and amplitude diffraction coefficients are vital to predict the field strength at the receiver accurately. In this paper, ... -

Spontaneous Mutation Reveals Influence of Exopolysaccharide on Lactobacillus johnsonii Surface Characteristics
(2013)As a competitive exclusion agent, Lactobacillus johnsonii FI9785 has been shown to prevent the colonization of selected pathogenic bacteria from the chicken gastrointestinal tract. During growth of the bacterium a rare but ... -
Determination of structural, spectrometric and nonlinear optical features of 2-(4-hydroxyphenylazo)benzoic acid by experimental techniques and quantum chemical calculations
(2013)The optimized geometrical structure, vibrational and electronic transitions, chemical shifts and nonlinear optical properties of 2-(4-hydroxyphenylazo)benzoic acid (HABA) compound were presented in this study. The ground ... -
Carbonic anhydrase activity from the gilthead sea bream (Sparus aurata) liver: The toxicological effects of heavy metals
(2013)Many studies have shown that metal ions may lead to oxidative stress in biological systems. Accordingly, DNA damage, protein modification, enzyme inhibition and activation, lipid peroxidation and many other effects may ... -
Biosorption properties of Morus alba L. for Cd (II) ions removal from aqueous solutions
(2013)The abundantly available industrial waste product Morus alba L. pomace (MAP) is one of the cost-effective biosorbent for removal of metal ions from aqueous solutions. Hence, in the present study, we aimed to test the ability ... -
Synthesis, conformational and spectroscopic characterization of monomeric styrene derivatives having pendant p-substituted benzylic ether groups
(2013)Three derivatives of styrene monomer, 4-chlorophenyl-4-vinylbenzyl ether (I), 4-methoxyphenyl-4-vinylbenzyl ether (II) and 4-ethylphenyl-4-vinylbenzyl ether (III) were synthesized. The synthesized two novel compounds (I ... -
Molecular structure, electronic properties, NLO, NBO analysis and spectroscopic characterization of Gabapentin with experimental (FT-IR and FT-Raman) techniques and quantum chemical calculations
(2013)Gabapentin (GP), structurally related to the neurotransmitter GABA (gamma-aminobutyric acid), mimics the activity of GABA and is also widely used in neurology for the treatment of peripheral neuropathic pain. It exists in ... -
Time-dependent effect of salicylic acid on alleviating cold damage in two barley cultivars differing in cold tolerance
(2013)The time-dependent effect of salicylic acid (SA) on alleviating cold damage in the Tokak (tolerant) and Akhisar (sensitive) varieties of barley (Hordeum vulgare) was investigated. Seedlings subjected to 0.0, 0.1, and 1 mM ... -
