Aydin, Nevzat
Sunnah, along with Quran, has become an essential criteria in the Islamic thought in determination and critique of hadith in terms of their relatedness to the Prophet. However, different approaches toward the determination and the content of the Sunnet as the essential factor in terms of the articulation and functionality of this criteria have been appeared in the long historical proccess. Thus, this paper, especially, is a step for articulating the place of ma'rouf/mashour sunnah, which was a dominant concept in the first two centuries of the Hijri calendar, in determination and critique method of hadith and also, its historical background and function. Even though there are some limitations of active usage of ma'rouf/mashour sunnah originated from different understandings of sunnah, it is an important and primary criteria developed from methodological structure of the determination and the critique of hadith, and also it is a criterion which keeps its value in its consistency, applicability and functionality.

Fistikoglu, Okan; Okkan, Umut
Statistical downscaling methods describe a statistical relationship between large-scale atmospheric variables such as temperature, humidity, precipitation, etc., and local-scale meteorological variables like precipitation. This study examines the potential predictor variables selected from the National Center for Environmental Prediction and National Center for Atmospheric Research (NCEP/NCAR) reanalysis data set for downscaling monthly precipitation in Tahtali watershed in Turkey. An approach based on the assessment of all possible regression types was used to select the predictors among the NCEP reanalysis data set, and artificial neural network (ANN)-based downscaling models were designed separately for each station in the basin. The results of the study showed that precipitation, surface and sea level pressures, air temperatures at surface, 850-, 500-, and 200-hPa pressure levels, and geopotential heights at 850- and 200-hPa pressure levels are the most explanatory NCEP/NCAR parameters for the study area. It was concluded that ANN-based downscaling models can be implemented to downscale coarse-scale atmospheric parameters to monthly precipitation at station scale by using the above parameters as inputs in the study area.

Dönel, Guldem; Dogan, Salih
In this study; cryptognathid mites collected from Kelkit Valley have been evaluated systematically. Three species belonging to the genus Cryptognathus Kramer, 1879 and six species belonging to the genus Favognathus Luxton, 1973 have been determined. Of these; Favognathus distortus (Kuznetsov, 1974) is new record for the Turkish fauna. In the introduction of the paper given on original description of this species, it has been mentioned that femur I has three setae as for all the species dealt with in the paper, but shown four setae on femur I in the figure. Khanjani & Ueckermann (2008) agreed to femur I with three setae in their identification key for all Favognathus. In Turkish specimens it has been determined that femur I bears four setae. One of the species determined from the research area, Favognathus kamili sp. nov., is new to science. The new species is similar to Favognathus dakotoensis (McDaniel & Bolen, 1979) and F. ochraceus (Summers & Chaudhri, 1965) in general appearance; however it can be distinguished from them by the anterior edge of hood smooth, dorsolateral punctations smaller size than centrals, coxa-sternal region without striae and reticulum, tc on tarsus II similar. Furthermore, it was decided that the Turkish specimens named as Favognathus orbiculatus (Livshitz) by Koc & Ayyildiz (1999), Dogan & Ayyildiz (2004), Akyol (2007) belonged to Favognathus kamili sp. nov. and these specimens subsequently were transferred to this new species. Additionally, the males of Favognathus bafranus Dogan, 2008 and the deutonymph females of Cryptognathus lagena Kramer, 1879 and Cryptognathus ozkani Dogan & Ayyildiz, 2001 have been found for the first time in this study.

Yurdakul, Muhammet; Ates, Sevket
Seismic isolated building structures are examined in this study. The triple concave friction pendulum (TCFP) is used as a seismic isolation system which is easy to be manufactured and enduring more than traditional seismic isolation systems. In the TCFP, take advantage of weight which pendulum carrying and it's geometry in order to obtain desirable result of seismic isolation systems. These systems offer advantage to buildings which subject to severe earthquake. This is result of damping force of earthquake by means of their internal constructions, which consists of multiple surfaces. As the combinations of surfaces upon which sliding is occurring change, the stiffness and effective friction change accordingly. Additionally, the mentioned the TCFP is modeled as of a series arrangement of the three single concave friction pendulum (SCFP) bearings. A two dimensional- and eight- story of a building with and without isolation system are used in the time history analysis in order to investigate of the effectiveness of the seismic isolation systems on the buildings. Results are compared with each other to emphasize efficiency of the TCFP as a seismic isolation device against the other friction type isolation system like single and double concave surfaces. The values of the acceleration, floor displacement and isolator displacement obtained from the results by using different types of the isolation bearings are compared each other. As a result, the findings show that the TCFP bearings are more effective devices for isolation of the buildings against severe earthquakes.

This study presents the determination of the optimum values of the design parameters in a tube with equilateral triangular cross-sectioned coiled wire inserts. The effects of the design parameters such as the ratio of the distance between the coiled wire and test tube wall to tube diameter (s/D), pitch ratio (P/D), ratio of the side length of equilateral triangle to tube diameter (a/D) and Reynolds number (Re) on heat transfer and pressure drop were investigated by using Taguchi method. The Nusselt number and friction factor were considered as performance parameters. An L9(34) orthogonal array was chosen as experimental plan. The goal of this study is to reach maximum heat transfer (i.e. Nusselt number) and minimum pressure drop (i.e. friction factor). First of all, each goal was optimized, separately. Then, all the goals were optimized together, considering the priority of the goals. Contribution ratios for each parameter on the heat transfer and pressure drop were determined. Consequently, the optimum results were found to be s/D = 0.0357, P/D = 1, a/D = 0.0714 and Re = 19800.

Yener, Engin; Hinislioglu, Sinan
The equi-viscous temperature range of asphalt has long been used in establishing the mixing temperature for mix designs and field production of hot mix asphalt (HMA). However, this method considers only binder viscosity to determine the mixing temperatures of the aggregate and asphalt. It is well known that depending on the gradation of aggregate and the type of plant and the mixing time. The appropriate mixing temperature for the proper coating may be lower than that of the viscosity based method. The excessive temperature causes the possible performance problems related to the hardening of the asphalt binder and increases the energy consumption, the gas emissions and fumes. In this study, a new method for the determination of asphalt-aggregate mixing temperature which considers the mixture properties was introduced to asphalt industry. The mixing temperatures of different nine mixtures were determined by both conventional and the proposed method. The effects of the nominal maximum aggregate size (NMAS), crushed coarse aggregate ratio (CCAR), the type of gradation, and the grade of binder on the mixing temperature were evaluated with an experimental study. Results show that decreasing NMAS, CCAR and increasing the grade of binder decreased the mixing temperature which is needed for proper coating. In addition, results showed that as going away from restricted zone of the Superpave gradation, the needed temperature to coat the aggregates decreased. The proposed method resulted in lower temperatures comparing to the conventional method on an average of 13°C. This means a possible energy saving of 14.3 x 10 9 kcal or 1362000 kg of crude oil in a year in Turkey. As a result, the new method is recommended due to not only the saving in energy but also decreasing the gas emissions and fume, and possible performance benefits.

The aim of this study is to investigate high school students' learning styles in terms of gender, grade level, type of school, graduation type of mother and father variables. The study was carried out at spring semester of 2010 with 660 high school students who were chosen as a sample from the cities of Artvin and Trabzon, in Turkey. "Kolb Learning Style Inventory" was used as a data collection tool. The inventory was used to determinate the students' learning styles as divergent, assimilator, convergent, and accommodator and the information sheet for demographic factors such as gender, grade level, school type, education of mother and father was used to collect information from students. The data were analyzed by using frequency, percent value, mean scores, standard deviation, independent samples t-test and one-way ANOVA. The results show that the dominant learning style among the students is accommodator and it is followed by divergent learning style. There was not significantly difference between students' learning style and gender except for "Active Experimentation (AE) and AE-RO", grade level "except for Concrete Experience (CE)", school type, education of mother "expert for Reflective Observation (RO)" and education of father.

The potential of removing Bomaplex Red CR-L dye from electro coagulation sludge has been investigated for different Bomaplex Red CR-L concentrations with varying adsorbent amount, temperature, pH and stirrer speed. Removal of Bomaplex Red CR-L is found to be high at lower pH values. The maximum adsorption of the dye has been achieved in aqueous solutions using 0.5g of calcinated sludge from electro coagulation at a pH of 2.0 within 20min. The Langmuir and Freundlich isotherm models were tested and it was found that the Langmuir equation was fitted better than the Freundlich equation. Maximum adsorption capacity (q m) was calculated as 192.31mg g -1 at 333K. In addition, the adsorption data obtained at various temperatures were successfully applied to pseudo first-order, pseudo second-order and intraparticle diffusion models. The rates of adsorption were found to conform to pseudo second-order kinetics with good correlation (R 2≥0.9997). This study showed that calcinated the sludge from electrocoagulation has a highly adsorbent capacity.

Altan, Burhanettin S.; Mollamahmutoglu, Murat
A multi-scale novel homogenization technique is introduced to model mechanical behavior of open-cell porous media. The proposed method consists of primarily four components. The first component is based on two assumptions. First, a random porous structure can be approximated by superimposing regular grids that are interacting with each other at "junction" points. The second component consists of replacing each grid by an equivalent continuum. The forces at the junction points are also replaced by interacting body forces. The third component is to represent the equivalent media by single medium by expressing the "average stresses" in the elastic mixture in terms of the "average displacement" It is discussed how to extract the information about the geometrical and mechanical properties of the grids by comparing the analytical and experimental data for the dispersion of waves propagating in porous medium.

Mollamahmutoglu, Murat; Yilmaz, Yuksel
This article investigates the penetrability of microfine cement suspensions prepared with Rheocem 900 with and without superplasticizer additive into various graded fine-to-medium sands into which chemical grout permeation is only possible. Initially, the basic rheological properties such as viscosity, setting time, and stability of microfine cement suspensions are studied. In addition, penetration performance of the suspensions into various graded fine to medium sand specimens under different grouting pressures is examined. Finally, the strength and permeability characteristics of various graded fine-to-medium sand specimens permeated with microfine cement suspensions are studied. It is found that a superplasticizer additive greatly increases the grouting performance of microfine cement and reduces the grouting pressure. Moreover, it is seen that the unconfined compressive strengths of sand specimens permeated with a cement grout without additive are slightly less than those of sand specimens permeated with cement grout and superplasticizer additive. Further-more, permeability tests on specimens permeated with cement grouts with or without a superplasticizer reveals that all specimens are impermeable (k<1 10 7 m=s).
