This paper presents a fundamental study on dewatering characteristics of filter cakes. Laboratory-scale batch pressure-filtration experiments were conducted on quartz, dolomite and andesite samples. having Gates-Gaudin-Schuhmann type of size distributions with different distribution parameters. The residual cake moisture and cake dewatering kinetics data were collected for filter cakes dewatered at varying applied pressure. Correlations for the entry pressure, residual saturation, pore size distribution index, and cake desaturation kinetics were studied in relation with particle size distribution characteristics. An assessment of previously recommended values of dewatering parameters and predictive correlation equations was presented with regard to their validity or limitations, and refinements were proposed for those giving poor fit.

Analyses on the Causality in Carbon Emission with respect to Economic Growth and Education ÜNLÜ, KAMİL DEMİRBERK; Kestel, Sevtap Ayşe (2017-01-01) This paper investigates the association between the level of carbon emission (CO2), economic growth and scholarly education levels in the countries chosen according to some specific characteristics using multivariate time series approach. It considers the impact of GDP and education enrollment, as a proxy of human capital, on the level of CO2 for the countries classified according to their economic developments and regional distribution. The analyses are assessed in three different cases two of which consid...
A SCREENING MODEL FOR EFFECTS OF LAND-DISPOSED WASTES ON GROUNDWATER QUALITY Ünlü, Kahraman; PARKER, JC; STEVENS, D; CHONG, PK; KAMIL, I (Elsevier BV, 1992-10-01) This paper describes a screening model for evaluating the migration of organic and inorganic contaminants leached from land-disposed wastes. The model is composed of a waste-zone release submodel, an unsaturated-zone transport submodel and a saturated-zone transport submodel. The waste-zone submodel assumes steady one-dimensional vertical flow through a uniform waste zone treated as a "stirred tank reactor". Soluble inorganic contaminants are assumed to exhibit a constant concentration in the leachate until...
The analysis on sun tracking and cooling systems for photovoltaic panels RÜSTEMLİ, SABİR; Dincer, Furkan; ÜNAL, EMİN; KARAASLAN, MUHARREM; Sabah, Cumali (Elsevier BV, 2013-06-01) This paper presents a review study on the effects of sun tracking and cooling systems. So far, many studies (and case studies too) have been analyzed and evaluated in the literature. Existing studies show that sun tracking system is significantly affecting energy generation capacity of photovoltaic panel. Other effecting parameter is the cooling system which has small effect on PV panel power generation but this totally depends on the location of installation system.

Investigation of the biological and photophysicochemical properties of new non-peripheral fluorinated phthalocyanines Çelik, Çetin; Akin, Mustafa; YAŞA ATMACA, Göknur; Sağlam, Özgül; ŞAKİ, NESLİHAN; ERDOĞMUŞ, Ali; Koçak, Makbule (2021-02-01) This study presents the synthesis of a series of new tetra-substituted phthalocyanines bearing 3,5-bis(trifluoromethyl)phenoxy groups at non-peripheral positions. The resulting macromolecules were characterized by performing different spectroscopic methods including H-1 NMR, UV-Vis, FT-IR, and mass spectroscopy. In this study, the synergistic effect of phthalocyanines used as colorants in ink formulas with other chemicals available was probed for the first time. The synergistic effect of methyl laurate on t...
A comparative study of the influence of N, N '-dialkyl vs. N, N '-diaryl-based electron donor ancillary ligands on photocurrent and photovoltage in dye-sensitized solar cells (DSSCs) Ashraf, Saba; Yıldırım, Erol; Akhtar, Javeed; Siddiqi, Humaira M.; El-Shafei, Ahmed (2017-08-21) In this study, we report the synthesis of a novel heteroleptic Ru(II)-sensitizer, (Ru(2,2'-bipyridine-4,4'dicarboxylic acid)-4,4'-bis(4-piperidin-1-yl) phenyl ethenyl)-(2,2'-bipyridine) (NCS)(2), denoted as SD-1; moreover, its photophysical, electrochemical, and photovoltaic performances were compared with those of N719 and K77-7 (N, N'-diaryl Ru-sensitizer, namely Ru(2,2'-bipyridine-4,4'-dicarboxylic-acid)4,4'- bis(2-(4-N, N'-diphenylaminophenyl) ethenyl)-2,2'-bipyridine (NCS) 2). The photovoltaic performa...
