In this paper, Taguchi method was applied to determine the optimum conditions for Zn (II) removal from aqueous solution by halloysite nanotubes (HNTs). An orthogonal array experimental design (L16 (45) which is of five control factors including pH, t (contact time), m (adsorbent mass), T (temperature) and C0 (initial concentration of Zn (II)) having four levels ...

Abstract In this paper, aiming at the chemical reaction system of solid-phase oscillating combustion, basic dynamic behavior laser in terms bifurcation diagram, Lyapunov exponent and complexity C0 is analyzed by using Matlab software, chaotic characteristics sensitivity to parameters combustion are expounded.

PURPOSE The purpose of this study was to record the effectiveness of Gold-Tite square abutment screws, tightened to 35 Ncm with a torque indicator, in maintaining a clinically stable implant/abutment connection. MATERIALS AND METHODS The study consisted of 73 patients who were treated with 110 Osseotite implants. All patients were restored with either pre-machined titanium or customized UCLA ...

This article describe the applicability of 1,4-disulfopiperazine-1,4-diium chloride ([Piper-(SO3H)2].2Cl) as a green, versatile and Brönsted acidic ionic catalyst in the promotion of the synthesis of phthalazine derivatives via one-pot three component reaction between aromatic aldehydes, 1,3-diketone derivatives and phthalhydrazide under solvent-free reaction cond...

The properties of crystalline materials tend to be strongly correlated with their structures, and the prediction crystal structure from only composition is a coveted goal in field inorganic materials. However, even for simplest compositions, such relies on complex network interactions, including atomic or ionic radii, ionicity, electronegativity, position periodic table, magnetism, name few imp...

The Zarivar Lake a freshwater lake in west of Kurdistan Province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. The present study aimed at evaluation of the Zarivar Lake using NSF- WQI as an indicator of water quality. WQI is a suitable tool to examine and classify spatial and temporal varia...

The application of biofertilizers constitutes one of the main components of nutrient management with a fundamental role in sustainable agriculture and the improvement of plant qualitative traits. The present research assessed the effect of various treatments of phosphate solubilizing bacteria including Pantoea agglomerans strain P5 and Pseudomonas putida</...
