DRAINS : a method of financially assessing drains used to mitigate waterlogging in south-western Australia

Seepage interceptor drains are often effective in mitigating waterlogging in duplex (sand over clay) soils on hill slopes in the sout-west. Spoon and W drains are sometimes effective in removing excess surface waters form clay flats. This report outlines a method to determine the long-term (1 to 20 years) cost-effectiveness of installing drains to mitigate waterlogging for each individual situation

Long-term carbon and nitrogen dynamics at SPRUCE revealed through stable isotopes in peat profiles

Peatlands encode information about past vegetation dynamics, climate, and microbial processes. Here, we used δ15N and δ13C patterns from 16 peat profiles to deduce how the biogeochemistry of the Marcell S1 forested bog in northern Minnesota responded to environmental and vegetation change over the past  ∼ 10000 years. In multiple regression analyses, δ15N and δ13C correlated strongly with depth, plot location, C∕N, %N, and each other. Correlations with %N, %C, C∕N, and the other isotope accounted for 80% of variance for δ15N and 38% of variance for δ13C, reflecting N and C losses. In contrast, correlations with depth and topography (hummock or hollow) reflected peatland successional history and climate. Higher δ15N in plots closer to uplands may reflect upland-derived DON inputs and accompanying shifts in N dynamics in the lagg drainage area surrounding the bog. The Suess effect (declining δ13CO2 since the Industrial Revolution) lowered δ13C in recent surficial samples. High δ15N from −35 to −55cm probably indicated the depth of ectomycorrhizal activity after tree colonization of the peatland over the last 400 years, as confirmed by the occasional presence of wood down to −35cm depth. High δ13C at  ∼ 4000 years BP (−65 to −105cm) could reflect a transition at that time to slower rates of peat accumulation, when 13C discrimination during peat decomposition may increase in importance. Low δ13C and high δ15N at −213 and −225cm ( ∼ 8500 years BP) corresponded to a warm period during a sedge-dominated rich fen stage. The above processes appear to be the primary drivers of the observed isotopic patterns, whereas there was no clear evidence for methane dynamics influencing δ13C patterns

Combining amenity with experience: exploring the hidden capital of a winescape experience

© The Author(s) 2016. Industry and government bodies have recommended augmentation of traditional production and marketing techniques as ways of increasing an industry’s profitability. This article values the amenity of the wine industry, a sensory experience that provides an array of opportunities both culturally to the tourist and economically to many regions across the world. Using the wine industry in the Central West region of New South Wales, Australia, we use input–output analysis to assess the economic impacts of this industry and the amenity hidden within. The industry not only provides jobs and commerce supporting local prosperity but also supplies a mixed production and consumption amenity from an agricultural product that meets the tourist’s leisure desire – an amenity that transcends from its origin in the vineyard to its destination at the table

How important is the name in predicting false recognition for lookalike brands?

An underexploited role for psychology in trademark law is the testing of explicit or implicit judicial assumptions about consumer behavior. In this article we examine an assumption that is common across Commonwealth countries, namely, that similar packaging is unlikely to cause consumer confusion provided the brand names are dissimilar. We began by selecting branded products commonly found in supermarkets. For each existing brand we created 2 novel (fictitious) brands with highly similar packaging to the existing brand. One of these "lookalike" products had a similar name, the other a dissimilar name. Across 2 yes/no and 1 forced-choice experiments using photographs of the real and fictitious products we looked at false recognition rates. Contrary to the judicial assumption participants largely ignored the brand names when making their decisions based on memory. It was only when the pictures of the products were placed side-by-side (in the forced-choice task) that they paid the brand name any significant attention

Production of intense, coherent, tunable narrow‐band lyman‐alpha radiation

Nearly transform limited pulses of 1216 Å radiation have been generated by sum frequency generation in 0.1 to 10 torr of mercury vapor. The summed input beams, consisting of photons at 3127 Å and 5454 Å originate in 1 MHz band‐width ring‐dye laser oscillators. The beams are amplified in pulsed‐dye amplifiers pumped by the frequency doubled output of a Nd:YAG laser. The 3127 Å photons are tuned to be resonant with the two‐photon 61S to 71S mercury transition. The VUV radiation can be tuned by varying the frequency of the third non‐resonant photon. We have also observed difference frequency generation at 2193 Å and intense fluorescence from the 61P state at 1849 Å. We have studied the intensity and linewidth dependence of the 1849 Å fluorescence and 1216 Å sum frequency signals on input beam intensity, mercury density, and buffer gas pressure and composition.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87716/2/49_1.pd

Effective RFID-based object tracking for manufacturing

International audienceAbstract Automated Identification and in particular, Radio Frequency Identification (RFID) promises to assist with the automation of mass customised production processes by simplifying the retrieval, tracking and usage of highly specialised components. RFID has long been used to gather a history or trace of object movements, but its use as an integral part of the automated control process is yet to be fully exploited. Such (automated) use places stringent demands on the quality of the sensor data collected and the method used to interpret that data. In particular, this paper focuses on the issue of correctly identifying, tracking and dealing with aggregated objects in customised production with the use of RFID. In particular, this work presents approaches for making best use of RFID data in this context. The presented approach is evaluated in the context of a laboratory manufacturing system that produces customised gift boxes
