Determination of the Freezing Effect on Unconfined Compression Strength and Permeability of Saturated Granular Soils
(Geomate Int Soc, 2015)Artificial ground freezing usage gradually rises in civil engineering applications as a soil supporting system. However, many unknown fundamental parameters have been still waiting discovery, especially for granular soil. ... -
Effect of length-to-diameter ratio of core sample on concrete core strength - Another look
(Amer Soc Testing Materials, 2008)Cores with diameters of 144,94,69, and 46 mm and length-to-diameter(1/d) ratios of 0.75,1,1.25,1.5,1.75, and 2, were removed from beam specimens produced from eight different concrete mixtures. Compressive strength tests ... -
The effect of particle size of body components on the processing parameters of semi transparent porcelain
(Elsevier Sci LTD, 2018)The effect of the particle size of quartz and K-feldspar on the sintering behaviour and technical properties of semi transparent porcelain were investigated. This study was implemented by "the Factorial Experimental Design ... -
Effects of fritted borax solid wastes on the properties of brick bodies
(2009)Brick is a structural ceramic material that, in modem times, is made by pressing clay into blocks and firing them to a requisite hardness in a kiln. In order to improve quality and usage fields of brick, it is obvious that ... -
Effects of Modification of Glassy Phase Composition on Sintering Temperature of Sanitaryware
(Gazi University, Fac Engineering Architecture, 2013)In this study, the effect of glassy phase viscosity and chemical composition of sanitaryware body was investigated. Additionally, the effects of these parameters on the sintering temperature were researched. The amount of ... -
Fixed-bed pyrolysis of cottonseed cake: Product yields and compositions
(Taylor & Francis, 1997)Fired-bed pyrolysis experiments have been conducted on a sample of cottonseed cake to determine the possibility of being a potential source of renewable fuels and chemical feedstocks. The effects of heating rate, pyrolysis ... -
GIS for urban conservation: Change detection and priority determination in historical Turkey
(2005)GIS is a very useful tool in the planning of urban conservation. GIS includes integration of vector and raster data, geographical referencing, correction and spatial adjustment. GIS analysis tools and map overlays improve ... -
Hydropyrolysis of extracted Euphorbia rigida in a well-swept fixed-bed tubular reactor
(Taylor & Francis Inc, 2002)Tubular reactor fixed-bed hydropyrolysis experiments have been conducted on a sample of extracted Euphorbia rigida to determine the possibility of being a potential source of renewable fuels and chemical feedstock. The ... -
ICF: An algorithm for large scale classification with conic functions
(Elsevier Science BV, 2018)Incremental Conic Functions (ICF) algorithm is developed for solving classification problems based on mathematical programming. This algorithm improves previous version of conic function-based classifier construction in ... -
Incremental conic functions algorithm for large scale classification problems
(Academic Press Inc Elsevier Science, 2018)In order to cope with classification problems involving large datasets, we propose a new mathematical programming algorithm by extending the clustering based polyhedral conic functions approach. Despite the high classification ... -
An Integrated MCDM Model for Occupational Safety Specialist Selection
(2017)For businesses in the public and private sectors, the selection process of occupational safety specialist is critical since these employees identify and prevent work-related hazards. In the field of human resource management, ... -
New dispatching rules and due date assignment models for dynamic job shop scheduling problems
(Inderscience Enterprises Ltd., 2018)In this paper, new due date assignment models and dispatching rules have been designed for the dynamic job shop scheduling problem. All of them have competitive results compared to the models from previous studies. The ... -
( Potentiometric and spectrophotometric determination of fluoride in some natural waters of Dogubayazit region). [Dogubayazit yoresindeki bazi su kaynaklarinda spektrofotometrik ve potansiyometrik yontemerle fluorur miktarlarinin arastirilmasi.]
(1983)Seventeen samples, out of 23, contained fluorides higher than recommended control limits for fluorides in drinking waters by WHO. It has been reported by many workers who studied in the area for the last 10 yr, that dental ... -
Quantitative determination of escin. A comparative study of HPLC and TLC-densitometry
(1994)Escin was quantitatively determined by both HPLC and TLC-densitometric techniques in horse-chestnut extracts. The results were found to be accurate, reproducible and in excellent agreement. -
Some physical effects of reaction rate on PbS thin films obtained by chemical bath deposition
(Elsevier Science BV, 2013)Thin films of polycrystalline lead sulfide (PbS) have been deposited on glass substrates at 303 +/- 1 K using chemical bath deposition (CBD). The precipitation of PbS on solid surfaces under four different reaction conditions ... -
Strained band edge characteristics from hybrid density functional theory and empirical pseudopotentials: GaAs, GaSb, InAs and InSb
(IOP Publishing LTD, 2016)The properties of a semiconductor are drastically modified when the crystal point group symmetry is broken under an arbitrary strain. We investigate the family of semiconductors consisting of GaAs, GaSb, InAs and InSb, ... -
Theoria, praxis, poiesis: A continuum scheme
(2011)The present age provides that the new production technologies are in a continuous experimental production in terms of both quantitative and rapidness criteria. Thinking and testing speed comes closer with these experiences. ... -
