Relative variation of ionic composition in a karstic lake under the theory of unweighted vs weighted logratio analysis
(IWA PUBLISHING, 2008)
The use of logratio analysis in limnological studies has proved to be effective for solving the problems of the constrained nature of compositional data. The method offers a graphical tool, the relative variation biplot, ...
Nitritation and denitritation of ammonium-rich wastewater using fluidized-bed biofilm reactors
(ELSEVIER SCIENCE BV, 2008)
Fluidized-bed biofilm nitritation and denitritation reactors (FBBNR and FBBDR) were operated to eliminate the high concentrations of nitrogen by nitritation and denitritation process. The dissolved oxygen (DO) concentration ...
Prevalence of common and atypical melanocytic nevi in Turkish children
(JOHN LIBBEY EUROTEXT LTD, 2008)
The incidence of malignant melanoma is increasing rapidly in the white population of the world. Therefore, it is necessary to know the etiological factors of malignant melanoma and to take preventive measures in high-risk ...
Evaluation of in vitro effect of Morus rubra (red mulberry) on survival of periodontal ligament cells
(MOSBY-ELSEVIER, 2008)
Objective. The purpose of this study was to determine the ability of the juice of Morus rubra fruit to serve as a temporary storage medium for the maintenance of periodontal ligament (PDL) cell viability of avulsed teeth. ...
Magnetoexciton binding energies for parabolic confinement in cylindrical quantum wire structures
(ELSEVIER SCIENCE BV, 2008)
In this work, using the effective mass approximation within variational approach, we have studied the behavior of the excitonic binding energies in a cylindrical quantum wire with a parabolic confinement under the effect ...
Investigation of pituitary functions in patients with acute meningitis: A pilot study
(SPRINGER, 2008)
Objective: Although long-term pituitary consequences of tuberculous meningitis are well documented in the literature, there have been few case reports of pituitary dysfunction after acute bacteria[ or viral meningitis. In ...
Assessment of Alveolar Bone Levels from Bitewing, Periapical and Panoramic Radiographs in Periodontitis Patients
(UNIV WEST INDIES FACULTY MEDICAL SCIENCES, 2008)
The aim of this study was to determine the relationship between loss of radiographic crestal bone height in panoramic, bitewing and periapical radiography and to probe the attachment loss after periodontal treatment. ...
Multi-objective optimization of some process parameters of a multi-gravity separator for chromite concentration
(ELSEVIER SCIENCE BV, 2008)
The multi-gravity separator (MGS) is one of the fine particle mineral concentration machines based on gravity separation. Concentration performance, indicators such as grade and recovery, depends on appropriate selection ...
Sulfotransferase 1A1 (SULT1A1) polymorphism and susceptibility to primary brain tumors
(SPRINGER, 2008)
Purpose Sulfotransferase 1A1 is a member of sulfotransferase family that plays an important role in the biotransformation of numerous carcinogenic and mutagenic compounds through sulfation. The present study has investigated ...
Combination of different size distributions for mineral particles by applying experimentally determined apparent mean shape factor
(TAYLOR & FRANCIS INC, 2008)
As is well known, the behavior of systems of fine particles is strongly dependent on the size of the individual particles, and the size effects become increasingly important as the particles become progressively smaller. ...
