Heavy metal concentrations in organs of Rudd, Scardinus erythrophthalmus L., 1758 populating Lake Karatas-Turkey
(Parlar Scientific Publications (P S P), 2006)Lake ecosystems are, in particular, vulnerable to heavy metal pollution. Rudd, Scardinius erythrophthalmus is one of the aquatic organisms affected by heavy metals. Therefore, heavy metals Fe, Zn, Mn, Cr, Pb and Cd were ... -
The integrity loss of physicomechanical properties of building stones when subjected to recurrent cycles of freeze-thaw (F-T) process
(Springer, 2006)In this study, a total of nearly 900 samples were obtained from 7 different rock types, also recognised as marbles of sedimentary and metamorphic origin and commercially used in the building of various monuments, art works ... -
Effect of shoulders on bending moment capacity of round mortise and tenon joints
(Forest Products Soc, 2006)Tests were conducted to determine the effect of close-fitting shoulders on the bending moment capacity of round mortise and tenon joints. Results indicate that close-fitting shoulders can substantially increase the strength ... -
Coverage-based, prioritized testing using neural network clustering
(Springer-Verlag Berlin, 2006)Graph-based algorithms are commonly used to automatically generate test cases for coverage-oriented testing of software systems. Because of time and cost constraints, the entire set of test cases generated by those algorithms ... -
Landfill site selection by using geographic information systems
(Springer, 2006)One of the serious and growing potential problems in most large urban areas is the shortage of land for waste disposal. Although there are some efforts to reduce and recover the waste, disposal in landfills is still the ... -

There may be strict empirical laws in biology, after all
(Springer, 2006)This paper consists of four parts. Part 1 is an introduction. Part 2 evaluates arguments for the claim that there are no strict empirical laws in biology. I argue that there are two types of arguments for this claim and ... -
Chemical composition effects onto antimicrobial and antioxidant activities of propolis collected from different regions of Turkey
(Springer, 2006)Chrysin, apigenin, flavonoids, flavanones, naringenin, ethyl oleate, 3-4-dimethoxy-cinnamic acid and 9-octadecenoic acid were the predominant components of propolis samples collected from different regions of Turkey. The ... -
Antioxidant and antimicrobial properties of ethanolic extract from Lepista nuda (Bull.) Cooke
(Springer, 2006)Antioxidant capacity and antimicrobial activities of Lepista nuda (Bull.) Cooke extracts obtained with ethanol were investigated. Four complementary test systems, namely DPPH free radical scavenging, beta-carotene/linoleic ... -
Contribution of Tourism to Economic Growth: A Panel Data Approach
(Routledge Journals, Taylor & Francis Ltd, 2006)Tourism is one of the fastest growing sectors of the world economy. Tourism development may promote economic growth both directly and indirectly, first by stimulating the growth of other sectors and second by increasing ... -
Gibberellic acid improves water deficit tolerance in maize plants
(Springer Heidelberg, 2006)The combination effects of water stress and gibberellic acid (GA(3)) Oil physiological attributes and nutritional status of maize (Zea mays L. cv., DK 647 F I) were studied in a pot experiment. Maize plants were grown in ... -
Effect of chronic exercise on immunoglobin, complement and leukocyte types in volleyball players and athletes
(Maghira & Maas Publications, 2006)BACKGROUND: The objective of this study was to investigate the effect of various sports disciplines on basic elements of the acquired and natural defense systems and to compare their results with that of non-sporting ... -
A new unsymmetrical vic-dioxime bearing salicylaldehyde 4-aminobenzoylhydrazone and its homo- and heterotrinuclear complexes with copper(II) and nickel(II) ions
(Pleiades Publishing Inc, 2006)A new vic-dioxinie, N-{4-[[(2-hydroxyphenyl)methylene]hydrazinecarbonyl]phenyl)aminoglyoxime (HP, was prepared by the reaction of anti-chloroglyoxime with salicylaldehyde 4-aminobenzoylhydrazone. The reaction of H3L with ... -
