Synthesis, crystal structure and spectroscopic studies of a mixed ligand copper (II) complex: trans-bis(succinimidato)-bis(benzylamino)Cu(II)
(Verlag der Zeitschrift fur Naturforschung, 2006)
The molecules of the title compound, [Cu(C11H13N 2O2)2], lie across centres of inversion in space group P21/c and are linked by intermolecular N-H?O and C-H?O hydrogen bonds. The central Cu atom has a slightly distorted ...
Gastric emptying, clearance rate, feeding periodicity and food consumption of the Black Sea jelly fish, Mnemiopsis leidyi (Agassiz)
(2007)
The feeding physiology of Mnemiopsis leidyi fed on Artemia salina were investigated under laboratory conditions. Multifactorial experimental designs were used to study the factors affecting gastrovascular emptying in M. ...
Microwave-assisted synthesis and characterization of novel metal-free and metallophthalocyanines containing four 14-membered tetraaza macrocycles
(Elsevier, 2007)
The novel tetrasubstituted metal-free phthalocyanine (6) and metallophthalocyanines (7, 8) bearing four 14-membered tetraaza macrocycles moieties on peripheral positions have been synthesized by cyclotetramerization reaction ...
Anatomical and pollen characters in the Genus epilobium L. (Onagraceae) from Northeast Anatolia
(2008)
Anatomical and palynological features of E. algidum Bieb., E. palustre L., E. ponticum Hausskn., E. confusum Hausskn., E. hirsutum L. and E. montanum L. collected from NE Anatolia were examined and evaluated by numerical ...
Critical state magnetostriction of type-II superconductors under viscous flux flow
(Elsevier, 2007)
We have studied theoretically the influence of the viscous flux flow on the magnetostriction for the infinite slab of type-II superconductors employing critical state model. The critical current density is chosen to be ...
Activation energy U(H) and pinning behavior of Yb-impurity-diffused YBa 2Cu 3O 7-x
(Wiley, 2007)
Superconducting Y123 samples were prepared by the solid-state reaction (SSR) method. To get a layer of Yb (thickness ?4 ?m) on the surface of one side of the sample an ultrahigh-vacuum electron-beam deposition system was ...
Assesment of trace elements in rainbow trout (Oncorhynchus mykiss) cultured in the marine aquaculture cages on the Black Sea Coast
(2007)
The concentrations of trace elements were determined in various tissues (internal organs, liver, abdominal and dorsal muscle) of individuals of cultured fishes obtained from two marine cage farms located on the coasts of ...
Measurement of the mass attenuation coefficients and electron densities for BiPbSrCaCuO superconductor at different energies
(Elsevier, 2007)
The mass attenuation coefficients for Bi, Pb, Sr, Ca, Cu metals, Bi2O3, PbO, SrCO3, CaO, CuO compounds and solid-state forms of Bi1.7Pb0.3Sr2Ca2Cu3O10 superconductor were determined at 57.5, 65.2, 77.1, 87.3, 94.6, 122 and ...
Microwave-assisted synthesis and antifungal activity of some new 1H-1,2,4-triazole derivatives
(Springer, 2008)
A number of 3-aryl-4-arylmethylideneamino-4,5-dihydro-1H-1,2,4-triazol-5- ones were synthesized by reaction of the corresponding aromatic aldehydes with 4-amino-3-aryl-1H-1,2,4-triazol-5-ones in anhydrous ethanol under ...
Essential oil compositions of four mushrooms: Scleroderma verrucosum, Cortinarius infractus, Hypholama capnoides and Hypholama fasciculare from Turkey
(2007)
The chemical composition of the essential oils obtained from four varieties of Mushrooms, ie. Scleroderma verrucosum, Cortinarius infractus, Hypholama capnoides and Hypholama fasciculare were analyzed by GC-MS. 13, 36, 8 ...
