The objective of this study is the removal of chromium from tannery wastewater by electrosorption on carbon prepared from lignocellulosic natural residue "peach stones' thermally treated. The followed steps for obtaining coal in chronological order were: cleaning, drying, crushing and finally its carbonization at 900°C. The characterization of the carbon material resulted in properties comparable to those of many coals industrially manufactured. The study of the dynamic adsorption of chromium...

Nanoporous carbon structures were synthesized by pyrolysis of grass as carbon precursor. The synthesized carbon has high surface area and pore volume. The carbon products were acid functionalized and characterized by Fourier transform infrared spectroscopy, X-ray diffraction, Brunauer?Emmett?Teller, transmission electron microscopy, and Energy Dispersive X-ray microanalysis. Acid functionalized nanoporous carbon was explored for use in removal of toxic Cr(VI) ions from aqueous media. An...

Activated carbon was synthesized from coconut shells. The Brunauer, Emmett and Teller surface area of the synthesized activated carbon was found to be 1640 m2/g with a pore volume of 1.032 cm3/g. The average pore diameter of the activated carbon was found to be 2.52 nm. By applying the size-strain plot method to the X-ray diffraction data, the crystallite size and the crystal strain was determined to be 42.46 nm and 0.000489897, respectively, which indicate a perfect crystallite structure. The...

Empirical research is warranted to determine effective ways to utilize paired associate music to facilitate recall and learning. The purpose of this study was to isolate and determine the effects of mode and rhythm on working memory as measured by sequential digit recall performance. Participants were music majors (n = 30) and nonmusic majors (n = 30) at a large comprehensive university. Participants listened to six different treatment stimuli of monosyllabic digits paired with: (a) a major...

In order to assess the role of aeration in stormwater wetlands, oxygen supply and consumption in a wetland treating runoff from livestock farms were estimated and analyzed. Furthermore, oxygen mass balance was conducted during day time and night time. Internal production by algal photosynthesis dominated the oxygen production particularly in the shallow marsh due to the large amount of algae. Consequently, algal respiration was also the major oxygen depletion element with nitrification and...

This study examines the job socialization process of independent corporate instructors. We conducted in-depth interviews with 13 independent corporate instructors. The interview questions and analysis framework were designed based on Miller s(2011) model that identified three stages of job socialization, that are anticipatory socialization, encounter, and metamorphosis. We revealed the challenges that the instructors had to face in each stage and identified the strategies taken to cope with the...

Objectives: This study applied a stress and coping model to understand one of the most frequent forms of problematic media use among adolescents, cyberbullying. Methods: Using data from the Korean Youth Panel Survey, the researchers found three major sources of stress for adolescents: parents (abusive behavior), school (academic stress), and friends (bullying victimization); these were seen as predictors of cyberbullying. The researchers also tested an important intra-personal factor, anger...

and this better trend growth is positive for current consumption and investment as it improves expectations for future income increase. This rapid U.S. productivity recovery can be attributed to the large-scale national R&D initiated during and after the financial crisis The policy implications suggested in this paper can be divided into two major categories. First, the implications for the mid- to long-term foreign policy are as follows. The U.S. is Korea's second largest export market and has...
