This study examined the differential effects of three color treatments incorporated into microcomputer software on the learning of geometric concepts by students with differential aptitudes. The color treatments were: monochrome, functional (the use of color for cueing), and nonfunctional (the indiscriminate use of color). The experimental software provided teachers with a detailed lesson outline to be used with one large-screen monitor for whole-class instruction using the discussion or recitation method of teaching. Ninth-grade students ( N = 109) were randomly assigned to the treatment groups. All students answered two aptitude tests, two geometric pretests, two geometric immediate posttests, the same posttests administered one month later, and an attitude questionnaire. All three experimental forty-minute lessons were delivered by the same teacher using the same software varying only the color treatment. Results revealed significantly better immediate and delayed learning of the functional group over both other groups with the low-aptitude students benefitting the most from the cueing provided by the functional-color software. Although high-aptitude students did not benefit more from the functional treatment than from the other two treatments, they showed the most positive attitudes toward this treatment whereas low aptitude students did not show any preference for the color system involved.

This study evaluated three UVC wavelengths (222, 254, and 282 nm) to degrade patulin introduced into apple juice or apple cider. The average UV fluences of 19.6, 84.3, 55.0, and 36.6 mJ·cm−2 achieved through exposure to UV lamps at 222-, 254-, and 282-nm wavelengths and the combination of these wavelengths, respectively, resulted in 90% reduction of patulin in apple juice. Therefore, the order of efficiency of the three wavelength lamps was as follows: far UVC (222 nm) &gt; far UVC plus (282 nm) &gt; UVC (254 nm). In terms of color, treatment of apple juice with 222 nm resulted in an increase in the L* (lightness) value but decreases in a* (redness) and b* (yellowness) values, although the changes were insignificantly different from the values for nontreated controls based on a sensory evaluation. The ascorbic acid loss in juice treated at 222 nm to support 90% reduction of patulin was 36.5%, compared with ascorbic acid losses of 45.3 and 36.1% in samples treated at 254 and 282 nm, respectively. The current work demonstrated that the 222-nm wavelength possesses the highest efficiency for patulin reduction in apple juice when compared with the reductions by 254 and 282 nm, with no benefit gained from using a combination of wavelengths.

H2o2 Oxidation

Macadamia shell contains a carbon content (47 - 49%), in addition, the shell contains 46.52% Oxidation, Hidro 6.10%, Nitrogen 0.36% and relatively low ash content of only 0.22%, this indicates the grain Macadamia has the potential to become activated carbon thanks to the above characteristics. This study was conducted to modify activated carbon by oxidizing agents to change the surface structure of activated carbon from hydrophobic to hydrophilic, non-polarizing to polarization, increasing the amount of adsorption simultaneously creating more durable links between dyes and activated carbon. Study of Methylene Blue wastewater treatment with coal from Maccadamia shell modified with H2O2 agent at H2O2 ratio : coal = 10:1. Research results show that Methylene Blue adsorption capacity reaches 1g /266,26mg Methylene Blue at optimal conditions corresponding to 25% concentration and 48 hours of soaking time. Analysis of infrared spectra showed that coal is modified by H2O2 agent with functional groups –OH, Carboxylic functional group C=O, group C-H in NH3, C–N group in Amine aliphatic or in Alcohol or Phenol and C–O bonding. Modified coal by H2O2 oxidation agent has Methylene Blue color treatment efficiency of 93.26%, corresponding to the original color of 474.67 Pt - Co at the respective optimal conditions pH = 8.5, dose of 1 g/L and treatment time of 60 minutes. Research results are similar to other research results and are applicable to color wastewater treatment.

Fenton Oxidation Process

The study introduced footprint analysis as a new methodology and focused on differentiating wastewater streams with the highest color content and optimizing the advanced oxidation process for the segregated streams for effective color removal from denim processing. Experiments were implemented to four segregated streams rather than the entire plant effluent. A flow proportional composite mixture of segregated streams was used for color removal experiments using the advanced oxidation process with ozone and hydrogen peroxide and Fenton oxidation as other alternatives. The latter yielded the best results achieving total removal of color below visual detection limit after an optimum reaction time of 10 minutes. The Fenton oxidation process was also applied to a representative sample from the plant effluent after the physical-chemical treatment sequence, where color absorbance levels were lowered at all wavelengths below 1.0 m-1. The merit of the new footprint approach was confirmed by the results, which provided a conclusive indication that color treatment at source, implemented on selected segregated wastewater streams, presented concrete advantages over the end of pipe treatment of the overall effluent.
