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 ...
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 ...
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 ...
Genetic diversity of gilthead seabream (sparus aurata) broodstocks as determined by RAPD-PCR
(2007)
The objective of this study was to determine the genetic diversity in gilthead seabream broodstocks from two hatcheries on the northern Aegean Coast of Turkey by RAPD-PCR. Forty primers were tested for each broodstock. ...
Newly synthesized bentonite-histidine (Bent-His) micro-composite affinity sorbents for IgG adsorption
(Elsevier, 2007)
Bentonite has several advantages for use as a support, including its lack of toxicity, chemical reactivity and hydrophilicity allowing easy fixation of biomolecules. A new approach was developed to obtain an efficient and ...
Molecular characterization of antibiotic resistant Escherichia coli strains isolated from tap and spring waters in a coastal region in Turkey
(2007)
A hundred and seventeen antibiotic-resistant Escherichia coli strains were isolated from public tap and spring waters which were polluted by fecal coliforms. There were no significant differences between two water sources ...
