Enhancement of Heat Transfer for Plate Fin Heat Exchangers Considering the Effects of Fin Arrangements
(TAYLOR & FRANCIS INC, 2018)
In the present study, the potential of rectangular fins with different fin types of inner zigzag-flat-outer zigzag (B-type) and outer zigzag-flat-outer zigzag (C-type) and with different fin angles of 30 degrees and 90 ...
Stranded sea turtle records between 2010 and 2017 in northern Aegean and Sea of Marmara
(ELSEVIER SCIENCE BV, 2018)
Studies on sea turtles in Turkey have mostly been concentrated on nesting beaches. Although there is no sea turtle nesting beaches on the northern Aegean Sea coast, there are stranded sea turtle records from the northern ...
Surface oxygen generated upon N2O activation on iron containing ZSM-5 type zeolites with different elemental composition
(ELSEVIER SCIENCE BV, 2012)
Various ZSM-5 zeolites with iron contents ranging from of 0.86 to 4.98 and Si/Al ratios of 11.5-140 were prepared by solid-state ion exchange with FeCl2. The catalysts were characterised by XRD, H-2-TPR and NH3-TPD. The ...
The joint properties of dissimilar aluminum plates joined by friction stir welding
(CARL HANSER VERLAG, 2010)
Friction stir welding (FSW) can be used to join dissimilar Al alloys which have different mechanical properties without causing any weld zone defects under a wide range of welding conditions. In this study, AA2024 and ...
GIS-based kinematic slope instability and slope mass rating (SMR) maps: application to a railway route in Sivas (Turkey)
(SPRINGER HEIDELBERG, 2012)
The paper discusses the use of kinematic stability and slope mass rating (SMR) maps in GIS based on field studies recording the relationships between the bedding/joint geometry relative to the orientation of the free face. ...
Study of electron-related optical responses in the Tietz-Hua quantum well: Role of applied external fields
(ELSEVIER SCIENCE BV, 2018)
In the present study, we theoretically reported the effects of applied external fields, such as intense laser field and electric and magnetic fields, on the optical absorption coefficient and refractive index changes in ...
Antibacterial Effects of Two Different Types of Laser and Aqueous Ozone Against Enterococcus faecalis in Root Canals
(MARY ANN LIEBERT, INC, 2013)
Objective: The purpose of this study was to investigate the antibacterial effects of two different types of laser and aqueous ozone in human root canals infected by Enterococcus faecalis. Background data: Many techniques ...
The Effect of the Plant Age and Growth Period on the Nutritional Substance, Chlorophyll and Steviol Glycoside Rates in Stevia (Stevia Rebaudiana Bertoni) Leaves
(TAYLOR & FRANCIS INC, 2018)
Stevia (Stevia rebaudiana Bertoni) is a perennial and subshrub herb of the Asteraceae family, which originates from South America. Stevia has long been used as a sweetener and herbal medicine throughout the world. The most ...
Dependence of impurity binding energy on nitrogen and indium concentrations for shallow donors in a GaInNAs/GaAs quantum well under intense laser field
(SPRINGER, 2011)
Within the framework of the effective-mass approximation, using a variational method, we have calculated the effect of intense laser radiation on the binding energy of the shallow-donor impurities in a Ga1-xInxNyAs1-y/GaAs ...
Performance of regional tuberculosis dispensaries in a province of Turkey in pre-DOTS era (1989-2002)
(DRUNPP-SARAJEVO, 2010)
Background: In recent years, very few dispensary staff has been striving to apply directly observed therapy (DOT) elsewhere in Turkey, but the overwhelming majority of TB dispensaries still continue their usual practice ...
