title: Influences of graphical image pairing on product preference

authors: Meng, Xiaosha

abstract: Many advertisements appear to rely on higher-order respondent conditioning to alter preference for a product brand. Given that higher-order conditioning is difficult to achieve, there may be other processes, such as those involved in stimulus equivalence, at work. The current experiment paired six “brand” stimuli with three different types of pictures. Three brands were paired directly with the pictures and the other three paired indirectly, using a stimulus equivalence procedure. The three types of pictures were “negative” (typical consequences of ingesting excessive sugar, such as heart disease, tooth decay, and diabetes), “neutral” (pictures of geometrical shapes) and “positive” pictures (pictures related to health and fitness). This research used a respondent procedure, which is more similar to real marketing methods than operant procedures, as used in previous research in this area. A preference assessment was conducted to evaluate transfer of function from the picture to the brands by investigating whether the pairings influenced participants’ preference for branded soft drinks. The results showed that negative pictures shifted preference more than positive pictures and direct pairing was more effective than an indirect pairing procedure.

title: Landfill leachate treatment: Using sequencing batch reactor technology to remove high ammonium concentration

authors: Lu, Philip Andrew

subjects: landfill leachate

abstract: Landfilling requires various consents and regulations in order to operate most effectively and cause minimal environmental issues to its immediate surroundings. The contaminated liquid produced from precipitation seeping through the layers of waste in landfills are generally called landfill leachate or leachate. Sequencing batch reactors (SBR) are fill-and-draw activated sludge systems that facilitate wastewater treatment in a singular reactor, while utilizing a sequence of different phases to create aerobic, anoxic, and sometimes anaerobic conditions. Multiple studies have been done that demonstrate the capacity of SBRs to treat wastewater for varying strengths of wastewater and concentration of contaminants, including ammonium. The objectives of the research are to: 1. run a lab-scale sequencing batch reactor to treat ammonium concentrations similar to that of landfill leachate; 2. design a full-scale sequencing batch reactor for landfills based on the bench-scale reactor’s ammonium removal potential; and 3. analyse the viability and economic feasibility of a SBR for treating landfill leachate.

Two lab-scale SBRs are used in the experiment. SBR 1 was run for 250 days of operation, while SBR 2 was run for only 130 days. These achieved ammonium removal at influent ammonium loading as high as 720 mg/L, and the SBR achieved ammonium removal efficiency of 90% to 100% with a TSS of 17 to 18 g/L during this most stable period of operation. pH control was required at higher influent ammonium loadings above 300 mg/L. Removal rates over the stable periods of operation are calculated to be at 1.65 and 1.55 mg NH4+ removed/g TSS/ per cycle for SBR 1 and 2, respectively. An ammonium removal rate of 0.0508 mg NH4+/L/min is calculated based on measurements using an ammonium ISE probe. Inhibition in ammonium removal due to low pH is observed. With extended aeration and pH control the ammonium removal continued as long as pH is maintained above 6.5. The oxygen consumption rate is also found to be at 0.01 mg DO/L/min, while the average mass transfer coefficient of O2 at 0.0144 min-1, and the percentage of oxygen transferred from gas to the mixed liquor calculated to be at 14.8%.

The full-scale SBR design is based on rates calculated from the experimental set-up and approximate leachate flow rate, based on precipitation, in the Waikato region. An area of 49 hectares landfilled is considered, which is similar to one of the class 1 municipal sanitary landfills in the region. A landfill leachate ammonium concentration range of 600 to 1500 mg/L is considered for the full-scale SBR design. The full-scale SBR is calculated to require a working volume of 8168 m3. The capital and operating cost of which shows high economic feasibility, and is estimated to be cost-effective compared to the cost of offsite treatment.
