Sustainability is a worldwide objective in balancing the gradual rise of human requirements and the decay of resources. In further aspect, the conceptual paper studies the sustainability performance of new techniques to control sewage contamination in order to prevent foul odors into the habitable space from drainage network, which is important for the healthiness and comfort of living environment. Waste drain pipe is a prominent facility in service engineering development and it is essential in regulating sewage contamination that is commonly obstructed by ungoverned disposal of debris by domestics and commercial buildings. This act is common and consistent in arising disturbance causing the failure of sewage management. This research emphasizes on the innovative establishment of a new controlling method upon sewage contamination known as Black Air Gun (BAG); this indicator is operated based on Perceived Sustainability Performance Indicators (PSPI). This indicator functions to evaluate the impact of BAG upon sewage contamination control. Furthermore, PSPI can acknowledge the sustainability issue of BAG usage in sewage management as a basis for evaluating the impact of BAG towards sewage contamination control. Adopting PSPI in this study will effectively provide a sustainable establishment attained for improvement of people’s quality of life in long term aspects.

Abstract. Continuous condensation particle (CP) observations were conducted from 1984 through 2009 at Neumayer Station under stringent contamination control. During this period, the CP concentration (median 258 cm−3) showed no significant long term trend but exhibited a pronounced seasonality characterized by a stepwise increase starting in September and reaching its annual maximum of around 103 cm−3 in March. Minimum values below 102 cm−3 were observed during June/July. Dedicated time series analyses in the time and frequency domain revealed no significant correlations between inter-annual CP concentration variations and atmospheric circulation indices like Southern Annular Mode (SAM) or Southern Ocean Index (SOI). The impact of the Pinatubo volcanic eruption and strong El Niño events did not affect CP concentrations. From thermodenuder experiments we deduced that the portion of volatile (at 125 °C) and semi-volatile (at 250 °C) particles which could be both associated with biogenic sulfur aerosol, was maximum during austral summer, while during winter non-volatile sea salt particles dominated. During September through April we could frequently detect nucleation events which occurred preferentially in the afternoon. Over the year, roughly 20 % of the particles could be assigned to the nucleation mode between 3 nm and 7 nm particle diameter.

Abstract. Continuous black carbon (BC) observations were conducted from 1999 through 2009 by an Aethalometer (AE10) and from 2006 through 2011 by a Multi-Angle Absorption Photometer (MAAP) at Neumayer Station (NM) under stringent contamination control. Considering the respective observation period, BC concentrations measured by the MAAP were somewhat higher (median ± standard deviation: 2.1 ± 2.0 ng m−3) compared to the AE10 results (1.6 ± 2.1 ng m−3). Neither for the AE10 nor for the MAAP data set a significant long-term trend could be detected. Consistently a pronounced seasonality was observed with both instruments showing a primary annual maximum between October and November and a minimum in April with a maximum/minimum ratio of 4.5/1.6 = 3.8 and 2.7/0.64 = 4.2 for the MAAP and AE10 data, respectively. Occasionally a secondary summer maximum in January/February was visible. With the aim to assess the impact of BC on optical properties of the aerosol at NM, we evaluated the BC data along with particle scattering coefficients measured by an integrating nephelometer. We found the mean single scattering albedo of ω550 = 0.992 ± 0.0090 (median: 0.994) at a wavelength of 550 nm with a range of values from 0.95 to 1.0.

The Impact

Organophosphates (OP) are frequently used worldwide as pesticides in both agriculture and human households leaving toxic residues in food or living environment. OP act through acetylcholinesterase (AChE) inhibition and acute poisoning carries a higher risk of mortality due to parasympathetic overstimulation. Long-term exposure leads to nervous, hepatic or renal dysfunction. Chlorpyrifos, one of the most commonly used compound appears to cause hyperglycemia, insulin resistance and the risk of developing diabetes after prolonged exposure. The aim of this article was to assess the impact of acute OP poisoning on glycemic status in weanling mice.

The Impact

This study investigates the impact of thought suppression over a 1-week interval. In two experiments with 80 university students each, we used the think/no-think paradigm in which participants initially learn a list of word pairs (cue-target associations). Then they were presented with some of the cue words again and should either respond with the target word or avoid thinking about it. In the final test phase, their memory for the initially learned cue-target pairs was tested. In Experiment 1, type of memory test was manipulated (i.e., direct vs. indirect). In Experiment 2, type of no-think instructions was manipulated (i.e., suppress vs. substitute). Overall, our results showed poorer memory for no-think and control items compared to think items across all experiments and conditions. Critically, however, more no-think than control items were remembered after the 1-week interval in the direct, but not in the indirect test (Experiment 1) and with thought suppression, but not thought substitution instructions (Experiment 2). We suggest that during thought suppression a brief reactivation of the learned association may lead to reconsolidation of the memory trace and hence to better retrieval of suppressed than control items in the long term.

The Impact

The paper studies the impact of the transition to the inflation targeting regime on the magnitude of the pass-through effect of the exchange rate to prices. We analyze cross-country panel data on developed and developing countries. It is shown that the transition to this regime of monetary policy contributes to a significant reduction in both the short- and long-term pass-through effects. This decline is stronger in developing countries. We identify the main channels that ensure the influence of the monetary policy regime on the pass-through effect, and examine their performance. In addition, we analyze the data of time series for Russia. It was concluded that even there the transition to inflation targeting led to a decrease in the dependence of the level of inflation on fluctuations in the ruble exchange rate.
